Tagged References Listing created 04-29-2006 1 PMID- 1999999999 AU - ZZZ TI - ZZZ: Coding Conventions and Summary of this database SO - ZZZ 2049 IN - ZZZ AB - MCM: Please do not delete this overview record, which sorts as the last record in all Sort By choices except RevYR or RevUI. Subject Matter of this Database: Primary scientific/medical articles and other selected source materials relating to CFS, FM, and (more in the past than recently) neurasthenia are included in this DB plus selected citations on directly or indirectly related medical subjects such as autoimmune manifestations, post-polio syndrome, Gulf War Syndrome, etc. I have generally omitted citations of published letters. In some cases, a relationship between the stated subjects of this database (CFS, FM, and NA) and the actual subject of some of the included citations may not be obvious (and may occassionally be lacking to anyone but myself). However, a broad multidisciplinary approach to the quest for understanding is needed for these wide-ranging, interrelated, and poorly understood disorders and some references are included to follow up observations made regarding CFS (e.g., the possible diagnostic role of 2',5'-oligoadenylate synthetase or the possible role of retroviruses). Books, pamphlets, advocacy materials, unpublished conference proceedings, and nonmedical articles dealing with the politics and economics of CFS etc. are generally not included. All but a few citations are in the English language, regrettably reflecting MCM's language limitations and not a presumption of language supremacy. I have attempted to include all articles that were at some time in the past influential or meritorious (i.e, published in peer-reviwed journals), whether or not they have subsequently been discredited or become outdated. This allows the interested observer to follow the historic twists and turns reflected in the medical literature, to identify where or by whom a particular concept might have first been published, or to simply marvel at the extraordinary difficulties and challenges that research in this field has encountered. Some older materials are included from non-peer-reviewed sources. I would be pleased to be advised of significant omissions, particularly in current peer-reviewed articles that appear in MEDLINE. If you are an author who feels the abstract summary I have included does not adequately represent your paper, please email to me (mcgoo@u.washington.edu) an abstract which I may add in the abstract section for your paper. Summary of Coding Conventions for CFSFMNA.MDB: (1) Articles for which the Medline PMID is not available (for example, those entered into the DB upon my reading a journal article) are given an arbitrary PMID greater than 1 billion based on the year and month of the publication. When the Medline citation becomes available with its final PMID, the two citations are merged when possible (some duplicates may have been inadvertently overlooked). In general, I currently prefer to wait until articles have been assigned PMIDs before incorporating them into this database. (2) MCM has added key-like abbreviations in each title to insure where possible that the subject of the article that justifies its inclusion in this database is included at least somewhere in the title as one of the following capitalized abbreviations: CFS, FM, NA, SLE, PPS, SS, ACLS, ME, etc. The categorization by these abbreviations is intended to be broadly inclusive for searching and filtering purposes and does not imply that an article with title = "Chronic Fatigue [CFS]" is in fact about strictly defined CFS rather than the more general Chronic Fatigue. MCM assumes that CFS and ME are equivalent and does not always include "ME" when "CFS" is included. To see articles about FM only, use Records | Edit Filter and after adding the field TI to the grid, set its criterion to ` Like "*FM*" ' where an asterix precedes and follows the abbreviation, all in quotes (see the Access manual for more information on filtering, including creating complex AND and OR filtering). Use Records | Apply Filter to view only these articles matching the criterion chosen. Use Records | Show All Records (or press any of the "SortBy" buttons) to remove the filtering restriction. (3) Summaries and editorializations in the abstracts that were entered by MCM are usually introduced by "MCM: " but may include verbatim quotes from the article, with or without quotes. (4) Unfamiliar abbreviations introduced into the citation during transfer into this DB can usually be found in the three tables of abbreviations included with Medrefs, namely "INAbbrev", "Journals", and "TIAbbrev". (5) MCM has in some cases rearranged the order of authors listed, shortened or truncated titles (usually indicated with "..."), omitted institutions and some coauthors, editorialized, etc. If you plan to use any of these citations in a paper for publication or for other formal purpose, please confirm exact wording of all fields listed as I cannot guarantee verbatim accuracy. (6) Citations are derived from multiple sources including the National Library of Medicine Gateway (http://gateway.nlm.nih.gov, formerly Internet Grateful Med), Ovid CD Plus, personal literature reviews, and CFS-NEWS.

AB - OBJECTIVES: To evaluate the possible relationship between the sexual and psychiatric status of premenopausal female patients with fibromyalgia compared with healthy controls. METHODS: A total of 48 female patients with fibromyalgia and 38 age-matched healthy controls were enrolled in the study. All the subjects were asked to complete the Female Sexual Function Index (FSFI) for sexual status and the State-Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI) for psychiatric assessment. Serum biochemical analysis was done, and the serum hormonal levels were analyzed. RESULTS: The mean BDI score for patients was significantly greater than the score for the controls (P = 0.017) and the mean FSFI score was significantly lower than the score for the controls (P = 0.001). According to the FSFI data, female sexual dysfunction was found in 26 patients (54.2%) with fibromyalgia and only 6 controls (15.8%), a significant difference (Pearson chi-square = 14.46, P = 0.000). When the subscores of each domain of FSFI were evaluated, the most common sexual problem was diminished desire in patients (n = 30, 62.5%) and controls (n = 11, 28.9%). In the correlation analysis, the FSFI score showed a significant negative correlation with the BDI (r = -0.337, P = 0.002) and STAI (r = -0.413, P = 0.004) scores. No significant correlation was revealed between the FSFI and BDI or FSFI and STAI scores in the controls. CONCLUSIONS: Depression is one of the emotional disorders commonly encountered in women with fibromyalgia, most possibly leading to sexual dysfunction. Thus, sexual dysfunction related to impaired psychiatric status should be considered a common problem in premenopausal women with fibromyalgia. 3 PMID- 16443425 AU - Blockmans D, Persoons P, Van Houdenhove B, Bobbaers H TI - Does methylphenidate reduce the Sx of CFS?

IN - D o Internal Med, U Hosp Gasthuisberg, Leuven, Belgium. daniel.blockmans@uz.kuleuven.ac.be AB - PURPOSE: Chronic fatigue syndrome is a clinical entity consisting of prolonged and debilitating fatigue in which concentration disturbances are very frequent. Until now, no medical treatment has shown any efficacy. The objectives of this study were to investigate the short-term effects of methylphenidate, an amphetamine derivative, on fatigue, concentration disturbances, and quality of life. SUBJECTS AND METHODS: A double-blind randomized placebo-controlled crossover study was conducted in 60 patients who fulfilled the 1994 Centers for Disease Control criteria for chronic fatigue syndrome and had concentration difficulties. Patients were enrolled between March 2003 and March 2004 at the outpatient department of a university hospital referral center for chronic fatigue syndrome patients. Random assignment to 4 weeks treatment with methylphenidate 2 x 10 mg/day, followed by 4 weeks of placebo treatment, or 4 weeks of placebo treatment, followed by methylphenidate treatment. Fatigue and concentration were measured with a Checklist Individual Strength (CIS) and a Visual Analogue Scale (VAS). RESULTS: Fatigue scores fell significantly during methylphenidate intake in comparison with baseline (mean difference: -0.7, P = .010 for VAS; mean difference: -11.8, P <.0001 for CIS) and in comparison with placebo (mean difference: -1.0, P = .001 for VAS; mean difference: -9.7, P <.0001 for CIS). Concentration disturbances, measured with a VAS improved significantly under methylphenidate treatment compared with baseline (mean difference: -1.3, P <.0001) and compared with placebo (mean difference: -1.1, P <.0001). A clinical significant effect (> or =33% improvement or CIS < or =76) on fatigue was achieved in 17% of patients, who were considered responders; on concentration in 22% of patients. CONCLUSIONS: Methylphenidate at a dose of 2 x 10 mg/day is significantly better than placebo in relieving fatigue and concentration disturbances in a minority of chronic fatigue syndrome patients. Further studies are needed to investigate the long-term effects of this treatment. 4 PMID- 16454725 AU - Burckhardt CS TI - Multidisciplinary approaches for management of FM. SO - Curr Pharm Des. 2006;12(1):59-66. IN - Oregon Health & Science U, Portland, OR 97239, USA. burckhac@ohsu.edu AB - Multidisciplinary approaches to fibromyalgia syndrome (FMS) treatment are advocated for treating the complex symptoms and problems confronting many patients. Exercise and cognitive-behavioral strategies together with patient education commonly comprise the multidisciplinary approach to treatment in clinical trials. A review of the research literature suggests that they are effective for decreasing pain and FMS impact and increasing self-efficacy and physical functioning. Limitations of the current evidence base include a lack of studies that include medication treatment as part of the multidisciplinary approach as well as lack of attention to the diversity of patient psychosocial issues that may interfere with treatment effectiveness. The review recommends that further randomized clinical trials be carried out with subgroups of patients using standardized outcome measurements, adequate treatment length and sufficient length of follow-up to be able to observe and document changes in patient symptoms and behaviors over time. 5 PMID- 16393878 AU - Cabyoglu MT, Ergene N, Tan U TI - The mechanism of acupuncture & clinical applications.

It has been determined that endomorphin-1, beta endorphin, encephalin, and serotonin levels increase in plasma and brain tissue through acupuncture application. It has been observed that the increases of endomorphin-1, beta endorphin, encephalin, serotonin, and dopamine cause analgesia, sedation, and recovery in motor functions. They also have immunomodulator effects on the immune system and lipolithic effects on metabolism. Because of these effects, acupuncture is used in the treatment of pain syndrome illnesses such as migraine, fibromyalgia, osteoarthritis, and trigeminal neuralgia; of gastrointestinal disorders such as disturbance at gastrointestinal motility and gastritis; of psychological illnesses such as depression, anxiety, and panic attack; and in rehabilitation from hemiplegia and obesity. 6 PMID- 16095585 AU - Chalmers RA, Jones MG, Goodwin CS, Amjad S TI - CFSUM1 & CFSUM2 in urine from pts w CFS are methodological artefacts.

IN - St George's Hosp MS, Cranmer Terrace, London SW17 0RE, UK. rachalmers@cimoa.org.uk AB - McGregor et al. reported increased levels of an unidentified urinary compound (CFSUM1) in patients with chronic fatigue syndrome (CFS), with reduced excretion of another unidentified compound (CFSUM2), and suggested the possibility of chemical or metabolic 'markers' for CFS. The identity of CFSUM1 as reported was erroneous and the identities of these compounds have remained unknown until now. Urine samples were obtained from 30 patients with ME/CFS, 30 age- and sex-matched healthy controls, 20 control patients with depression and 22 control patients with rheumatoid arthritis. Samples were prepared using the published methods of McGregor et al. to produce heptafluorobutyryl-isobutyl derivatives of urinary metabolites. Alternative preparations utilised isopropyl, n-butyl and trifluoroacetyl derivatives. These were separated and identified using gas chromatography-mass spectrometry. CFSUM2 was identified as being partially derivatised [isobutyl ester-mono-heptafluorobutyryl (HFB)] serine. CFSUM1 was identified as partially derivatised pyroglutamic acid, being the isobutyl ester without formation of a HFB derivative. Both CFSUM1 and CFSUM2 are artefacts of the sample preparation procedure and previously reported quantitative abnormalities of CFSUM1 and CFSUM2 in urine from patients with ME/CFS are also artefactual. Pyroglutamic acid may be of primarily dietary origin. The methods used cannot provide reliable qualitative or quantitative data on urinary metabolites. No clinical or biochemical significance can be drawn between these compounds in ME/CFS or any other clinical conditions. 7 PMID- 16454719 AU - Clayton AH, West SG TI - Combination therapy in FM.

Research indicates that the origin of the disease is most likely multifactorial. Treatment should therefore be tailored accordingly.

However, few studies have been done to identify predictors of disease severity. MATERIALS AND METHODS: A total of 174 men with CP/CPPS and 111 women with IC completed questionnaires to quantify symptom severity and identify demographic, medical and psychosocial characteristics. Symptom severity was assessed with the National Institutes of Health CPSI in men, and the O'Leary-Sant ICSI and problem index in women. Univariate and multivariate analyses were performed to identify characteristics predictive of worse symptoms. RESULTS: The mean National Institutes of Health CPSI score in men was 15.32, and the mean O'Leary-Sant ICSI and problem index in women was 19.17. The most commonly reported comorbidities were allergies, sinusitis, erectile dysfunction and irritable bowel syndrome in men, and allergies, urinary incontinence, sinusitis and irritable bowel syndrome in women. In the 2 sexes self-reported urinary frequency and urgency, worse depression scores and lower education level were independent predictors of worse symptom severity. In men additional independent predictors were self-reported pelvic pain, fibromyalgia and previous heart attack, and in women an additional independent predictor was postmenopausal status. CONCLUSIONS: There are several common medical conditions associated with urological pelvic pain syndromes in men and women. Few of them were predictive of symptoms severity in this analysis. Self-reported pelvic pain symptoms, education and depression severity were the factors most strongly predictive of symptom severity in patients with CP/CPPS and IC. 9 PMID- 16514330 AU - Dobkin PL, Sita A, Sewitch MJ TI - Predictors of adherence to Rx in women w FM.

METHODS: Participants were 142 women recruited from tertiary care hospitals or the community and 10 rheumatologists. Participants' demographic, clinical, and psychosocial characteristics, as well as patient-physician discordance, were assessed at the index visit. Adherence was assessed 6 months later. Multivariable generalized estimating equations were used to identify predictors of general adherence and adherence to medication. RESULTS: The average age of participants was 50.9 years (SD=10.2) and the median duration of FM was 32 months. Participants reported extensive use of health services and medications. The mean score for general adherence was 61.0 (SD=22.4; range 0-100) and 52.9% of the cohort reported at least one form of behavior reflecting nonadherence to medications. More general adherence was significantly predicted by lower patient-physician discordance on patient well-being and lower patient psychological distress. Medication adherence was significantly predicted by higher affective pain and lower patient psychological distress. CONCLUSIONS: Adherence is influenced by both clinical (patient-physician discordance and pain) and psychological (distress) factors in women with FM. Improvements in these domains may improve adherence in FM. 10 PMID- 16386400 AU - Finset A, Graugaard PK, Holgersen K TI - Salivary cortisol response after a medical interview: the impact of physician communication behaviour, depressed affect & alexithymia.

AB - OBJECTIVE: To explore if - and possibly how - a medical interview may affect adrenocortical activity in musculo-skeletal pain patients with and without alexithymia. METHODS: Female patients (N = 54) recruited from a patient organization for fibromyalgia completed the Toronto Alexithymia Scale (TAS-20) and subgroups with, respectively, low and high scores were selected for participation. Seven physicians conducted consultations attempting to vary their communication in accordance with given guidelines. All consultations were videotaped and analysed by The Roter Interaction Analysis System (RIAS) to evaluate the actual content of the consultations. RESULTS: An increase in depressed affect from pre- to post-interview was associated with relatively high cortisol levels 24 h after the consultation, but only in patients with alexithymia. Psychosocial questions from the physician were associated with increased depressed affect immediately following the interview, but not with cortisol responses at any time. CONCLUSION: In patients with deficient affect regulation, increase in depressed affect after a medical interview may be associated with delayed effects in adrenocortical activity, possibly mediated by rumination. PRACTICE IMPLICATIONS: Providers should be sensitive to potential deficits of affect regulation in their patients. 11 PMID- 16401454 AU - Gordon C, Emiliozzi C, Zartarian M TI - Use of a mechanical massage technique in the Rx of FM: a preliminary study. SO - Arch Phys Med Rehabil. 2006 Jan;87(1):145-7. IN - Memorial Hosp o Union County, Marysville, OH 43043, USA. AB - OBJECTIVE: To investigate how a mechanical massage technique (LPG technique) could contribute to the treatment of fibromyalgia. DESIGN: Feasibility study. SETTING: A single center. PARTICIPANTS: Ten women having a preexisting diagnosis of fibromyalgia based on American College of Rheumatology criteria were enrolled. INTERVENTION: Subjects received a total of 15 sessions of mechanical massage administered by a physical therapist once a week. MAIN OUTCOME MEASURES: The Fibromyalgia Impact Questionnaire and a physical examination scoring tender points (number, pain intensity). Evaluations were conducted at the screening visit, after 7 sessions (V7), and after completion of 15 sessions (V15). RESULTS: Most of the parameters (pain intensity, physical function, number of tender points) showed a significant improvement at V15 compared with screening. CONCLUSIONS: The findings suggest the possibility that the studied intervention might be associated with positive outcomes in women with fibromyalgia, and support the need for a controlled clinical trial to determine its efficacy. 12 PMID- 16382004 AU - Greenfield JR, Samaras K TI - Evaluation of pituitary function in the fatigued patient: a review of 59 cases.

AB - OBJECTIVE: The aim of this study was to review the results of dynamic pituitary testing in patients presenting with fatigue. METHODS: We reviewed clinical histories and insulin tolerance test (ITT) results of 59 patients who presented with fatigue and other symptoms of glucocorticoid insufficiency over a 4-year period. All patients referred for ITT had an early-morning cortisol level of <400 nM and a low or normal ACTH level. RESULTS: Peak cortisol and GH responses following insulin-induced hypoglycaemia were normal in only seven patients (12%). Median age of the remaining 52 patients was 47 years (range, 17-67 years); all but five were female. Common presenting symptoms were neuroglycopaenia (n = 47), depression (n = 37), arthralgia and myalgia (n = 28), weight gain (n = 25), weight loss (n = 9), postural dizziness (n = 15) and headaches (n = 13). Other medical history included autoimmune disease (n = 20; particularly Hashimoto's thyroiditis, Graves' disease and coeliac disease), postpartum (n = 8) and gastrointestinal (n = 2) haemorrhage and hyperprolactinaemia (n = 13). 31 subjects had peak cortisol levels of <500 nM (suggestive of ACTH deficiency; 18 of whom had levels < 400 nM) and a further six had indeterminate results (500-550 nM). The remaining 15 subjects had normal cortisol responses (median 654 nM; range, 553-1062 nM) but had low GH levels following hypoglycaemic stimulation (5.9 mU/l; 3-11.6 mU/l). CONCLUSION: Our results suggest that patients presenting with fatigue and symptoms suggestive of hypocortisolism should be considered for screening for secondary adrenal insufficiency, particularly in the presence of autoimmune disease or a history of postpartum or gastrointestinal haemorrhage. Whether physiological glucocorticoid replacement improves symptoms in this patient group is yet to be established. 13 PMID- 16454722 AU - Gur A TI - Physical therapy modalities in management of FM. SO - Curr Pharm Des. 2006;12(1):29-35. IN - D o Physical Med & Rehabilitation, Med Faculty, Dicle U, 21280 Diyarbakir, Turkey. alig@dicle.edu.tr AB - The etiology of fibromyalgia syndrome (FM) is uncertain and the prognosis for symptomatic recovery is generally poor. A wide variety of interventions are used in the management of FM. There is, however, no clear consensus on the treatment of choice and FM remains relatively refractory to treatment. Therefore, prevention, causal therapy and rehabilitation are not possible. FM patients frequently use alternative therapies, indicating dissatisfaction or ineffectiveness of traditional medical therapy. Alternative therapies are generally perceived to be more "natural" and as a result, to have fewer adverse effects. Despite the positive results found, the number of publications related to the application of physical therapy modalities such as acupuncture, transcutaneous electrical stimulation, laser, biofeedback, electrotherapy and magnetic field is still scant, especially concerning FM treatment. The demonstration of a long-term effective intervention for managing the symptoms associated with FM is needed. Multidisciplinary approaches to management include physical and medical therapeutic strategies. Treatment modalities should be individualised for patients based on target symptoms and impairment in functioning. Patience and positive attitude on part of the physician and active involvement of patients and their families in treatment are likely to enhance improvement. It can be concluded that there is a need for larger, more systematic and methodologically sound randomised controlled clinical trials to evaluate the effectiveness of physical therapy modalities of managing FM. We will review some of the existing studies of physical therapy relevant in the treatment of FM and give some practical advice for their use. 14 PMID- 16361589 AU - Heesen C, Nawrath L, Reich C, Bauer N, Schulz KH, Gold SM TI - Fatigue in multiple sclerosis: an example of cytokine mediated sickness behaviour?

IN - D o Neurology, U Hosp Eppendorf, Martinistrasse 52, D-20246 Hamburg, Germany. heesen@uke.uni-hamburg.de AB - BACKGROUND: Fatigue is a major complaint of multiple sclerosis (MS) patients. However, little is known about its pathophysiological mechanisms. Evidence from chronic fatigue syndrome and studies on sickness behaviour suggest that immune and neuroendocrine factors may play a causative role in the development of fatigue. METHODS: We compared whole blood stimulatory capacity for pro- (TNFalpha, IFNgamma) and anti-inflammatory cytokines (IL-10) as well as hypothalamo-pituitary-adrenal (HPA) axis function in 15 MS patients with marked fatigue and 15 patients without fatigue as determined by the Fatigue Severity Scale (FSS). RESULTS: Proinflammatory cytokines were significantly higher (TNFalpha: 478.9 v 228.2 pg/ml, p = 0.01; IFNgamma: 57.6 v 27.8 pg/ml; p = 0.01) in MS patients with fatigue. Furthermore, TNFalpha values significantly correlated with daytime sleepiness as measured by the Epworth Sleepiness Scale (r = 0.64, p = 0.001). Controlling for disease activity (as measured by the Cambridge Multiple Sclerosis Basic Score), disease duration, Expanded Disability Status Scale, and depression further increased the correlation of cytokine production and fatigue. HPA axis activity was not related to fatigue but was modestly correlated with cognitive impairment. CONCLUSION: Our data suggest that fatigue in MS is at least partially mediated through activation of proinflammatory cytokines. In line with earlier findings, HPA axis dysfunction seems not to be relevant in MS fatigue pathogenesis but appears to be linked to cognitive impairment. Our findings suggest that increased levels of inflammatory cytokines may be involved in MS fatigue. Investigation of cytokine profiles may increase the understanding of fatigue pathogenesis in MS. 15 PMID- 16385513 AU - Hughes G, Martinez C, Myon E, Taieb C, Wessely S TI - The impact of a Dx of FM on health care resource use by primary care pts in the UK: an observational study based on clinical practice. SO - Arthritis Rheum. 2006 Jan;54(1):177-83. IN - Medicines & Healthcare Products Regulatory Agency, Market Towers, 1 Nine Elms Lane, London SW8 5NQ, UK. AB - OBJECTIVE: To investigate the impact of a diagnosis of fibromyalgia (FM) in clinical practice on health care resource use in the UK. METHODS: Rates of visits, prescriptions, referral, and diagnostic testing were estimated in patients who had been diagnosed as having FM between 1998 and March 2003 in UK primary care and compared with those in matched controls. Rates were calculated in 6-month intervals from 10 years before until 4 years after the FM diagnosis. RESULTS: Patients (2260) were newly diagnosed as having FM; 81.3% were women. Their mean age was 49 years. FM patients had considerably higher rates of visits, prescriptions, and testing from at least 10 years prior to diagnosis compared with controls. By the time of diagnosis, FM patients had 25 visits and 11 prescriptions per year compared with 12 visits and 4.5 prescriptions per year in controls. Visit rates were highest for depression, followed by fatigue, chest pain, headache, and sleep disturbance. Following diagnosis, visits for most symptoms and health care use markers declined, but within 2-3 years, most visits rose to levels at or higher than those at diagnosis. CONCLUSION: Primary care patients who had been diagnosed as having FM reported higher rates of illness and health care resource use for at least 10 years prior to their diagnosis, which suggests that illness behavior may play a role. Being diagnosed as having FM may help patients cope with some symptoms, but the diagnosis has a limited impact on health care resource use in the longer term, possibly because there is little effective treatment. 16 PMID- 16291298 AU - Husser D, Bollmann A, Kuhne C, Molling J, Klein HU TI - Evaluation of noncardiac chest pain: diagnostic approach, coping strategies & quality of life. [FM] SO - Eur J Pain. 2006 Jan;10(1):51-5. IN - D o Cardiology, U Hosp Magdeburg, Leipziger Str. 44, 39120 Magdeburg, Germany. AB - BACKGROUND: Approximately 30% of coronary angiograms are negative for significant coronary artery disease and patients are classified as having noncardiac chest pain (NCCP). So far, no systematic diagnostic approach to patients with NCCP investigating for possible esophageal, psychiatric and musculoskeletal abnormalities exists. Furthermore, coping strategies and quality of life are poorly characterized in NCCP patients. METHODS AND RESULTS: A simple diagnostic approach was applied to 37 consecutive patients (21 female, age 61+/-12 years) with angina-like chest pain and normal coronary angiograms. Twenty-one patients were found to suffer from psychiatric disorders (combined anxiety (A) and depression (D): n = 10, D: n = 5, panic disorder (P): n = 3, somatization (S): n = 3) based on their Symptom Check List 90 scores and according to DSM IV-R criteria. Sixteen patients had an improvement of their chest pain after oral esomeprazole (40 mg for 7 days) and were therefore diagnosed with gastroesophageal reflux disease (GERD). Musculoskeletal abnormalities including chostochondritis (n = 4), thoracic spondylodynia (n = 1), and fibromyalgia (n = 1) were found in six patients. Multiple diagnoses were confirmed in six patients with GERD (additional D n = 3, additional musculoskeletal disorders n = 3). Patients with psychiatric disorders showed a diminished quality of life (MOS-SF 36), more frequent chest pain, less treatment satisfaction (Seattle Angina Questionnaire) and more rumination (Trier Coping Scales) compared to GERD patients. CONCLUSIONS: Immediate combined psychiatric and orthopedic evaluation as well as esomeprazole administration following exclusion of coronary artery disease may confirm the causes of noncardiac chest pain. Identification of psychiatric disorders seems especially warranted since these patients experience a reduced quality of life and exhibit pathologic coping strategies. 17 PMID- 16464229 AU - Iovino P, Tremolaterra F, Consalvo D, Sabbatini F, Mazzacca G, Ciacci C TI - Perception of electrocutaneous stimuli in irritable bowel syndrome.

AB - BACKGROUND AND AIM: Irritable bowel syndrome (IBS) and fibromyalgia syndrome (FMS) are common conditions with some similarities, but different perceptual responses to somatic and visceral stimuli. The purpose of this study was to assess in a large group of IBS patients the somatic perception by transcutaneous electrical nerve stimulation (TENS) and its relation to the level of severity and presence of FMS. METHODS: In 99 patients grouped by the validated functional bowel disorder severity index (FBDSI) in mild, moderate, and severe IBS and in 33 healthy controls (HC), we studied discomfort thresholds and perception of somatic stimuli at control (hands and elbows) and active (trapezius) sites by TENS and by using a specific questionnaire. RESULTS: The use of TENS showed that IBS showed significant higher thresholds and lower perception cumulative score compared to HC. The severity of IBS is significantly associated with age and mean control site values for discomfort and borderline associated with gender in the ordinal model constructed for the ascending series protocol. The severity of IBS is also significantly associated with the active cumulative perception score in the long stimulus protocol. Due to limited sample size of IBS men with FMS, analyses of discomfort thresholds and cumulative perception score by FMS were done only for women. IBS women without FMS had significantly higher mean control site values for discomfort and significantly lower active cumulative perception score than HC. IBS women with FMS had significantly lower mean active site values for discomfort thresholds than IBS women without FMS (Dunn's test p < 0.05). CONCLUSIONS: IBS patients showed somatic hypoalgesia to electrical stimuli. The severity of IBS and the presence of FMS influence the perception of somatic stimuli induced by TENS. 18 PMID- 16139959 AU - Kajantie E, Phillips DI TI - The effects of sex & hormonal status on the physiological response to acute psychosocial stress.

IN - D o Epidemiology & Health Promotion, The Nat Public Health Inst, Mannerheimintie 166, 00300 Helsinki, Finland. eero.kajantie@helsinki.fi AB - Whether one is male or female is one of the most important determinants of human health. While males are more susceptible to cardiovascular and infectious disease, they are outnumbered by women for many autoimmune disorders, fibromyalgia and chronic pain. Recently, individual differences in the physiological response to stress have emerged as a potentially important risk factor for these disorders. This raises the possibility that sex differences in prevalence of disease could at least in part be explained by sex differences in the nature of the physiological response to stress. In a psychophysiological laboratory, the autonomic nervous system response can be provoked by many different stressors including physical, mental and psychosocial tasks, while the hypothalamic-pituitary-adrenal axis (HPAA) response seems to be more specific to a psychosocial challenge incorporating ego involvement. The responses of both systems to different psychosocial challenges have been subject to extensive research, although in respect of sex differences the HPAA response has probably been more systematically studied. In this review, we focus on sex differences in HPAA and autonomic nervous system responses to acute psychosocial stress. Although some differences are dependent on the stressor used, the responses of both systems show marked and consistent differences according to sex, with the phase of the menstrual cycle, menopausal status and pregnancy having marked effects. Between puberty and menopause, adult women usually show lower HPAA and autonomic responses than men of same age. However, the HPAA response is higher in the luteal phase, when for example post stress free cortisol levels approach those of men. After menopause, there is an increase in sympathoadrenal responsiveness, which is attenuated during oral hormone replacement therapy, with most evidence suggesting that HPAA activity shows the same trends. Interestingly, pregnancy is associated with an attenuated response of the sympathoadrenal and HPAA systems at least as assessed by biochemical stimulation. It is likely that these sex differences in autonomic function are a result of estrogen exposure which attenuates sympathoadrenal responsiveness. The HPAA is however somewhat more complex and evidence now suggests the influence of other modifiers such as arginine vasopressin (AVP) and the regulation of circulating cortisol bioavailability by corticosteroid-binding globulin (CBG). The pronounced and multi-faceted sex differences in stress responsiveness suggest that they are a product of a strong evolutionary pressure. We hypothesise that this has to a great deal been driven by the need to protect the fetus from the adverse effects of maternal stress responses, in particular excess glucocorticoid exposure. Studying this hypothesis may have a fundamental impact on our understanding about how adult health is set during early life and how adult disease could be prevented in men and women. 19 PMID- 16423291 AU - Kassam A, Patten SB TI - Major depression, FM & labour force participation: a population-based cross-sectional study.

IN - Health Services Research D, Inst o Psychiatry, King's Coll, London, UK. aliya.kassam@iop.kcl.ac.uk AB - BACKGROUND: Previous studies have documented an elevated frequency of depressive symptoms and disorders in fibromyalgia, but have not examined the association between this comorbidity and occupational status. The purpose of this study was to describe these epidemiological associations using a national probability sample. METHODS: Data from iteration 1.1 of the Canadian Community Health Survey (CCHS) were used. The CCHS 1.1 was a large-scale national general health survey. The prevalence of major depression in subjects reporting that they had been diagnosed with fibromyalgia by a health professional was estimated, and then stratified by demographic variables. Logistic regression models predicting labour force participation were also examined. RESULTS: The annual prevalence of major depression was three times higher in subjects with fibromyalgia: 22.2% (95% CI 19.4 - 24.9), than in those without this condition: 7.2% (95% CI 7.0 - 7.4). The association persisted despite stratification for demographic variables. Logistic regression models predicting labour force participation indicated that both conditions had an independent (negative) effect on labour force participation. CONCLUSION: Fibromyalgia and major depression commonly co-occur and may be related to each other at a pathophysiological level. However, each syndrome is independently and negatively associated with labour force participation. A strength of this study is that it was conducted in a large probability sample from the general population. The main limitations are its cross-sectional nature, and its reliance on self-reported diagnoses of fibromyalgia. 20 PMID- 16385512 AU - Katz RS, Wolfe F, Michaud K TI - FM Dx: a comparison of clinical, survey, & American College of Rheumatology criteria. SO - Arthritis Rheum. 2006 Jan;54(1):169-76. IN - Rush U Med Ctr, Chicago, IL, USA. AB - OBJECTIVE: The American College of Rheumatology (ACR) criteria for fibromyalgia are the de facto criteria used for research. However, ACR criteria are not generally utilized by nonrheumatologists, and rheumatologists may diagnose fibromyalgia in patients who do not satisfy the ACR criteria. We undertook this study to determine concordance between ACR criteria and clinician diagnosis and between proposed survey criteria and clinician diagnosis. METHODS: Consecutive patients in a clinical practice setting were evaluated by tender point examination, survey criteria for fibromyalgia (Regional Pain Scale score > or =8 and fatigue score > or =6), and clinical diagnosis. RESULTS: Among the 206 patients, the clinician diagnosed fibromyalgia in 49.0%, while 29.1% satisfied ACR criteria and 40.3% satisfied survey criteria. Clinical and survey criteria were concordant in 74.8% of cases (kappa = 0.49 [95% confidence interval 0.36, 0.60]). Clinical criteria and ACR criteria were concordant in 75.2% of cases (kappa = 0.50 [95% confidence interval 0.35, 0.59]), and survey criteria and ACR criteria were concordant in 72.3% (kappa = 0.40 [95% confidence interval 0.25, 0.51]). The ACR tender point criterion (> or =11) was not a factor in clinical and survey criteria. However, the tender point count was useful in clinical diagnosis. CONCLUSION: Clinical diagnosis and ACR and survey criteria are moderately concordant (72-75%) and address a common pool of symptoms and physical findings. Because there is no gold standard for fibromyalgia diagnosis and because fibromyalgia is often viewed as a trait diagnosis, all methods of diagnosis have utility. The survey method has the advantage that it does not require physical examination. 21 PMID- 16454723 AU - Kurtais Y, Kutlay S, Ergin S TI - Exercise & cognitive-behavioural Rx in FM syndrome.

The pathophysiology is not well understood and treatment remains a challenge. Although pharmacological therapy is still the primary treatment choice, a long-term effective intervention has not been demonstrated yet. Thus, besides pharmacotherapy, other multimodal interventions are often used. Exercise and cognitive-behavioural treatments which exist in the multimodal approach and encompass largely self-managed strategy, are reviewed in this article. Although, there is a great number of exercise studies, the large diversity of outcome measures and measurement instruments that have been used in studies, varying intensity and types of exercises, small sample sizes, high attrition rates, large variability in baseline function, symptom severity and psychosocial status limit to come to a conclusion about the efficacy of exercise in the treatment of fibromyalgia syndrome. There are also inconclusive results about the efficacy of cognitive-behavioural treatment because of limited number of studies with small sample sizes of patients with fibromyalgia syndrome. However, the results of the trials overall demonstrate the beneficial effects of both different types of exercise and cognitive-behavioural treatment, on the other hand, there is still a need for larger, more systematic and randomised controlled trials to evaluate the effectiveness. 22 PMID- 16395760 AU - Leavitt F, Katz RS TI - Distraction as a key determinant of impaired memory in pts w FM.

Frank_Leavitt@rush.edu AB - OBJECTIVE: Patients with fibromyalgia (FM) frequently complain of poor memory, severe enough to affect job performance and to lead to disability. Yet common practices in neurocognitive examinations often fail to document cognitive abnormalities that match the severity of their memory complaints. Often, neuropsychologists gauge memory competence with measures free of distraction and produce high rates of normality on neurocognitive examination. We hypothesized that neurocognitive tests encoded with a source of stimulus competition that interferes with the processing and/or absorption of information would be better than others in gauging FM memory competence. METHODS: Thirty-five patients with FM and 35 controls, matched for age and sex, and presenting with complaints of memory loss, completed cognitive measures with and without stimulus competition. RESULTS: Eleven (31.4%) patients with FM showed impairment on at least one measure of memory encoded free of stimulus competition. By comparison, 30 (85.7%) showed impairment on at least one measure encoded with a source of stimulus competition. The Auditory Consonant Trigram detected impairment in 29 (82.6%) cases, and was by far the most sensitive measure. FM patients lost information at a 58% rate following a 9 second distraction. This loss was disproportionate to the loss shown by both age matched controls with memory problems (40%) and to normative values (20%) based on individuals free of memory problems. CONCLUSION: The findings validate the perception of failing memory in patients with FM and are the first psychometric based evidence to our knowledge of short-term memory problems in FM linked to interference from a source of distraction. Adding a source of distraction caused the majority of FM patients to retain new information poorly, and may be integral to an understanding of FM memory problems. Much needs to be learned about why new information is disproportionately lost by FM populations when a source of distraction enters the experiential field. 23 PMID- 16454718 AU - Littlejohn GO, Guymer EK TI - FM syndrome: which antidepressant drug should we choose.

IN - Departments Rheumatology & Med, Monash U at Monash Med Centre, Level 3 Block E, 246 Clayton Road, Clayton, Melbourne, Victoria 3168, Australia. geoff.littlejohn@med.monash.edu.au AB - Fibromyalgia syndrome [FM] has core clinical features of widespread pain and widespread abnormal tenderness. The specific cause of the altered neurophysiology that underpins these clinical manifestations remains unclear. However, increased sensitisation of neural networks that relates to pain, as well as interacting mechanoreceptors, appear important targets for modulation by pharmacological agents. Further, many FM patients have emotional distress and some are depressed. Antidepressant agents have therapeutic benefits in FM. If depression is present antidepressant drugs will provide typical benefits to mood but not always to other key outcome measures, such as pain or tenderness. Selective serotonin receptor reuptake blockers are not as effective for overall FM improvement as drugs that block both serotonin and norepinephrine in a relatively balanced way. Thus tricyclic antidepressants will improve many important FM outcomes but are effective in only about 40 percent of individuals. Newer agents of this class, such as duloxetine and milnacipran, show improvement in key FM outcomes in about 60 percent of patients. Longer term studies will indicate the durability of these responses and the overall tolerance of the drugs. Any drug therapy will need to be integrated with appropriate education, exercise and attention to psychological modulatory factors to achieve best results. 24 PMID- 16442982 AU - Mannerkorpi K, Svantesson U, Broberg C TI - Relationships between performance-based tests & pts' ratings of activity limitations, self-efficacy, & pain in FM.

Kaisa.mannerkorpi@rheuma.gu.se AB - OBJECTIVE: To investigate the relationship between performance-based tests, ratings of activity limitations, self-efficacy, and pain in fibromyalgia. DESIGN: Descriptive. SETTING: University hospital. PARTICIPANTS: Sixty-nine women with fibromyalgia (mean age, 45+/-7.8y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The patients completed 4 performance-based tests focusing on muscle power function and 3 unloaded arm movements. The patients rated their activity limitations by means of the subscales of physical function (PF) and pain on the Fibromyalgia Impact Questionnaire (FIQ), the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and the Arthritis Self-Efficacy Scale (ASES). Spearman correlation coefficient (rho) and multivariate regression analysis were conducted. RESULTS: The highest correlations were found between the 6-minute walk test (6MWT) (rho range, -.48 to .68) and the activity limitations and between hand grip strength (rho range, -.34 to .57) and the activity limitations. The regression analysis indicated that hand grip strength explained 25% of the variation in the SF-36 PF scale. The 6MWT plus endurance of the shoulder muscles explained 24% of the variation in the FIQ PF scale and the 6MWT plus active abduction of the shoulder explained 48% of the variation in the ASES function scale. Correlations between the performance-based tests and the activity limitations tended to be higher than those between performance and pain. CONCLUSIONS: The majority of the performance-based tests and the patients' subjective ratings of activity limitations showed significant relationships. The 6MWT and hand grip strength, reflecting activity limitations in the SF-36, FIQ, and ASES, are recommended for use in clinical research and in the clinical examination when planning treatment for patients with fibromyalgia. 25 PMID- 16376018 AU - McIver KL, Evans C, Kraus RM, Ispas L, Sciotti VM, Hickner RC TI - NO-mediated alterations in skeletal muscle nutritive blood flow & lactate metabolism in FM.

AB - The purpose of these investigations was to determine if differences exist in skeletal muscle nutritive blood flow and lactate metabolism in women with fibromyalgia (FM) compared to healthy women (HC); furthermore, to determine if differences in nitric oxide-mediated systems account for any detected alterations in blood flow and lactate metabolism and contribute to exertional fatigue in FM. FM (n = 8) and HC (n = 8) underwent a cycle ergometry test of aerobic capacity, a muscle biopsy for determination of nitric oxide synthase (eNOS, nNOS, iNOS) content, and microdialysis for investigation of muscle nutritive blood flow and lactate metabolism. During prolonged (3h) resting conditions, the ethanol outflow/inflow ratio (inversely related to blood flow) increased in FM over time compared to HC (P < 0.05). FM also exhibited a reduced nutritive blood flow response to aerobic exercise (P < 0.05). There was an increase in dialysate lactate in response to acetylcholine in FM, and to sodium nitroprusside in both groups, with a greater rise in dialysate lactate in FM (P < 0.05). The iNOS protein content was higher in FM and was negatively correlated with total exercise time (r(2) = 0.462, P < 0.05). In conclusion: (1) There is reduced nutritive flow response to aerobic exercise and reduced maximal exercise time in FM that might relate to higher iNOS protein content and contribute to exertional fatigue in FM; (2) The increased dialysate lactate in FM in response to stimulation of NOS or a nitric oxide donor suggest that FM may be more sensitive than HC to the suppressive effect of nitric oxide on oxidative phosphorylation. 26 PMID- 16150550 AU - Mommersteeg PM, Heijnen CJ, Verbraak MJ, van Doornen LJ TI - Clinical burnout is not reflected in the cortisol awakening response, the day-curve or the response to a low-dose dexamethasone suppression test.

To date, studies on HPA-axis functioning in burnout have showed inconsistent results. In the present study, a large sample (n=74) of clinically diagnosed burnout individuals, mostly on sick-leave, were included and compared with 35 healthy controls. Salivary cortisol was sampled on 2 days to determine the cortisol awakening response (CAR) and the day-curve. In addition, the dexamethasone suppression test (DST) was applied to assess the feedback efficacy of the HPA-axis. There were no differences observed in the CAR, day-curve or CAR after DST in the burnout group as compared to a healthy control group. Burnout shows overlap in symptoms with chronic fatigue syndrome (CFS) and depression. Therefore, differential changes in HPA-axis functioning that resemble the hypo-functioning of the HPA-axis in CFS, or rather the hyper-functioning of the HPA-axis in depression, might have obscured the findings. However, no effect of fatigue or depressive mood on HPA-axis functioning was found in the burnout group. We concluded that HPA-axis functioning in clinically diagnosed burnout participants as tested in the present study, seems to be normal. 27 PMID- 16454726 AU - Ozgocmen S TI - New strategies in evaluation of therapeutic efficacy in FM syndrome.

The use of multiple outcome variables reflecting the complexity of FM and co-morbid syndromes, makes it difficult to evaluate the efficacy or effectiveness of the treatment in clinical trials. Additionally researchers inevitably rely on patients' self-reported outcome data, which is prone to error and bias. In this paper, new researches in the field of FM and practical issues on methodology of pain assessment (visual analogue scales, paper or electronic diaries and compliance), core outcome domains in chronic pain assessment (IMMPACT recommendations), and advances in neuroimaging techniques like functional magnetic resonance imaging have been reviewed. Consequently, clinicians and researchers have various highly validated and adequate outcome domains to assess FM symptoms and new researches continue to add new valuable domains. Nevertheless the current problem is to conclude, which treatment works best for whom and which are the outcome domains suitable for FM patients or patients' subgroups with different prominent features. Standardised and appropriate core outcome domains for FM clinical trails will encourage more complete investigations, relevant outcome reporting and well-designed multicenter trials. 28 PMID- 16503466 AU - Parker NR, Barralet JH, Bell AM TI - Q fever.

Few illnesses have been discussed so extensively. The existence of the disorder has been questioned, its underlying pathophysiology debated, and an effective treatment opposed; patients' organisations have participated in scientific discussions. In this review, we look back on several controversies over CFS with respect to its definition, diagnosis, pathophysiology, and treatment. We review issues of epidemiology and clinical manifestations, focusing on the scientific status of CFS. Modern neuroscience and genetics research offer interesting findings for new hypotheses on the aetiology and pathogenesis of the illness. We also discuss promising future issues, such as psychopathophysiology and mechanisms of improvement, and suggest multidisciplinary prospective studies of CFS and fatigue in the general population. These studies should pay particular attention to similarities to and differences from functional somatic syndromes and other fatiguing conditions. 30 PMID- 16438814 AU - Saidi G, Haines L TI - The management of children w CFS-like illness in primary care: a cross-sectional study.

AB - BACKGROUND: Most studies on children with chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) have been undertaken in tertiary care and little is known about their management in primary care. AIM: To describe the characteristics of patients aged 5-19 years with CFS-like illness in primary care and to examine how GPs investigate and manage patients. DESIGN OF STUDY: Descriptive retrospective questionnaire study. SETTING: Sixty-two UK GP practices in the MRC General Practice Research Framework (GPRF). METHOD: One hundred and twenty-two practices were approached; 62 identified 116 patients consulting a GP with severe fatigue lasting over 3 months. Practice nurses and GPs completed questionnaires from medical notes and patients completed postal questionnaires. RESULTS: Ninety-four patients were considered by a clinical panel, blind to diagnosis, to meet the Oxford CFS criteria with a fatigue duration of 3 months. Seventy-three per cent were girls, 94% white, mean age was 12.9 years and median illness duration 3.3 years. GPs had principal responsibility for 62%. A diagnosis of CFS/ME was made in 55%, 30% of these within 6 months. Fifty per cent had a moderate illness severity. Paediatric referrals were made in 82% and psychiatric referrals in 46% (median time of 2 and 13 months respectively). Advice given included setting activity goals, pacing, rest and graded exercise. CONCLUSIONS: Patient characteristics are comparable to those reported in tertiary care, although fewer are severe cases. GPs have responsibility for the majority of patients, are diagnosing CFS/ME within a short time and applying a range of referral and advice strategies. 31 PMID- 16454724 AU - Sarac AJ, Gur A TI - Complementary & alternative medical therapies in FM.

There is no permanent cure for FM; therefore, adequate symptom control should be goal of treatment. Clinicians can choose from a variety of pharmacologic and nonpharmacologic modalities. Unfortunately, controlled studies of most current treatments have failed to demonstrate sustained, clinically significant responses. CAM has gained increasing popularity, particularly among individuals with FM for which traditional medicine has generally been ineffective. Some herbal and nutritional supplements (magnesium, S- adenosylmethionine) and massage therapy have the best evidence for effectiveness with FM. Other CAM therapies such as chlorella, biofeedback, relaxation have either been evaluated in only one randomised controlled trials (RCT) with positive results, in multiple RCTs with mixed results (magnet therapies) or have positive results from studies with methodological flaws (homeopathy, botanical oils, balneotherapy, anthocyanidins and dietary modifications). Another CAM therapy such as chiropractic care has neither well-designed studies nor positive results and is not currently recommended for FM treatment. Once CAM therapies have been better evaluated for safety and long-term efficacy in randomised, placebo-controlled trials, they may prove to be beneficial in treatments for FM. It would then be important to assess studies assessing cost-benefit analyses comparing conventional therapies and CAM. 32 PMID- 16541995 AU - Singh BB, Wu WS, Hwang SH, Khorsan R, Der-Martirosian C, Vinjamury SP, Wang CN, Lin SY TI - Effectiveness of acupuncture in the Rx of FM.

AB - CONTEXT: Fibromyalgia syndrome (FMS) is a prevalent musculoskeletal disorder associated with pain, mood state alteration, and disability. A structured and effective treatment plan for palliative care has not been established. The genesis of FMS is not clear. FMS occurs primarily in adult women. DESIGN: Using a quasi-experimental clinical design and following the criteria of the American College of Rheumatology (ACR), for FMS, 21 participants completed the study. The mean age was 53.6 years. The data were collected at baseline and at 1 and 2 months. Acupuncture treatments included 17 points for FMS symptoms, and 8 outcome measures were collected. RESULTS: The Fibromyalgia Impact Questionnaire (FIQ) showed significant differences at 1 and 2 months. For the SF-12, 3 subscales showed significant differences between baseline and 2 months. Four of 6 items were significantly changed. The mean number of general health symptoms was significantly decreased by 2 months. For the Catastrophe Index, significant differences were found for baseline vs 2 months. Pain threshold scores were significantly different at end of treatment for 5 bilateral tender points. There was significant improvement in Beck Depression items for both 1- and 2-month periods. In a multivariate regression model, 5 covariates were included--age, number of weeks in treatment, number of doctors treating, number of general symptoms, and baseline FIQ score. The results indicated significant age effect. This analysis showed that the higher the FIQ score, the more positive the change experienced by study participants. Number of weeks in treatment, number of doctors who treated, and total number of general health symptoms did not have a significant effect on outcomes. CONCLUSIONS: Significant improvement was experienced by participants at 8 weeks of treatment. Acupuncture treatment as delivered was effective at reducing FMS symptoms in this outcome study. 33 PMID- 16454721 AU - Staud R TI - Are tender point injections beneficial: the role of tonic nociception in FM.

FM patients show psychophysical evidence for mechanical, thermal, and electrical hyperalgesia. To fulfill FM criteria, the mechanical hyperalgesia needs to be widespread and present in at least 11 out of 18 well-defined body areas (tender points). Peripheral and central abnormalities of nociception have been described in FM and these changes may be relevant for the increased pain experienced by these patients. Important nociceptor systems in the skin and muscle seem to undergo profound changes in FM patients by yet unknown mechanisms. These changes may result from the release of algesic substances after muscle or other soft tissue injury. These pain mediators can sensitize important nociceptor systems, including the transient receptor potential channel, vanilloid subfamily member 1 (TRPV1), acid sensing ion channel (ASIC) receptors, and purino-receptors (P2X3). Subsequently, tissue mediators of inflammation and nerve growth factors can excite these receptors and cause substantial changes in pain sensitivity. FM pain is widespread and does not seem to be restricted to tender points (TP). It frequently comprises multiple areas of deep tissue pain (trigger points) with adjacent much larger areas of referred pain. Analgesia of areas of extensive nociceptive input has been found to provide often long lasting local as well as general pain relief. Thus interventions aimed at reducing local FM pain seem to be effective but need to focus less on tender points but more on trigger points (TrP) and other body areas of heightened pain and inflammation. 34 PMID- 16504053 AU - Tanaka M, Sadato N, Okada T, Mizuno K, Sasabe T, Tanabe HC, Saito DN, Onoe H, Kuratsune H, Watanabe Y TI - Reduced responsiveness is an essential feature of CFS: a fMRI study.

METHODS: Using functional magnetic resonance imaging, we studied brain responsiveness in 6 male chronic fatigue syndrome patients and in 7 age-matched male healthy volunteers. Responsiveness of auditory cortices to transient, short-lived, noise reduction was measured while subjects performed a fatigue-inducing continual visual search task. RESULTS: Responsiveness of the task-dependent brain regions was decreased after the fatigue-inducing task in the normal and chronic fatigue syndrome subjects and the decrement of the responsiveness was equivalent between the 2 groups. In contrast, during the fatigue-inducing period, although responsiveness of auditory cortices remained constant in the normal subjects, it was attenuated in the chronic fatigue syndrome patients. In addition, the rate of this attenuation was positively correlated with the subjective sensation of fatigue as measured using a fatigue visual analogue scale, immediately before the magnetic resonance imaging session. CONCLUSION: Chronic fatigue syndrome may be characterised by attenuation of the responsiveness to stimuli not directly related to the fatigue-inducing task. 35 PMID- 16444659 AU - Tharakan B, Manyam BV TI - Botanical therapies in chr fatigue.

AB - The effect of melatonin, a chronobiotic drug, was explored in 29 patients with chronic fatigue syndrome (CFS) and Dim Light Melatonin onset (DLMO) later than 21.30 hours, reflective of delayed circadian rhythmicity. The patients took 5 mg of melatonin orally, 5 h before DLMO during 3 months. Their responses to the checklist individual strength (CIS), a reliable questionnaire measuring the severity of personally experienced fatigue, were assessed twice with a 6-week interval immediately before the treatment and once after 3 months treatment. In the pre-treatment period the fatigue sub-score improved significantly. After treatment, the total CIS score and the sub-scores for fatigue, concentration, motivation and activity improved significantly. The sub-score fatigue normalized in two of the 29 patients in the pre-treatment period and in eight of 27 patients during treatment. This change was significant. In the patients with DLMO later than 22.00 hours (n=21) the total CIS score and the sub-scores for fatigue, concentration and activity improved significantly more than in the patients (n=8) with DLMO earlier than 22.00 hours.

Despite extensive literature describing the epidemiology and clinical aspects of CFS, it has been recalcitrant to diagnostic biomarker discovery and therapeutic intervention. This is due to the fact that CFS is a complex illness defined by self-reported symptoms and diagnosed by the exclusion of medical and psychiatric diseases that may explain the symptoms. Studies attempting to dissect the pathophysiology are challenging to design as CFS affects multiple body systems, making the choice of which system to study dependent on an investigators area of expertise. However, the peripheral blood appears to be facilitating the molecular profiling of several diseases, such as CFS, that involve bodywide perturbations that are mediated by the CNS. Successful molecular profiling of CFS will require the integration of genetic, genomic and proteomic data with environmental and behavioral data to define the heterogeneity in order to optimize intervention. 38 PMID- 16454720 AU - Wallace DJ TI - Is there a role for cytokine based therapies in FM.

They assist in the regulation of cell growth and repair and also have immune modulating properties. Cytokines play a role in diverse clinical processes and phenomena such as fatigue, fever, sleep, pain, stress and aching. A review of the fibromyalgia literature and related studies suggest that IL-1, IL-6 and IL-8 are dysregulated in the syndrome. Therapies directed against these cytokines may be of potential importance in the management of fibromyalgia. 39 PMID- 16420193 AU - Weiner DK, Sakamoto S, Perera S, Breuer P TI - Chronic low back pain in older adults: prevalence, reliability, & validity of physical examination findings.

IN - D o Med, Div o Geriatric Medicine, U o Pittsburgh, Pittsburgh, Penn, USA. dweiner@pitt.edu AB - OBJECTIVES: To develop a structured physical examination protocol that identifies common biomechanical and soft-tissue abnormalities for older adults with chronic low back pain (CLBP) that can be used as a triage tool for healthcare providers and to test the interobserver reliability and discriminant validity of this protocol. DESIGN: Cross-sectional survey and examination. SETTING: Older adult pain clinic. PARTICIPANTS: One hundred eleven community-dwelling adults aged 60 and older with CLBP and 20 who were pain-free. MEASUREMENTS: Clinical history for demographics, pain duration, previous lumbar surgery or advanced imaging, neurogenic claudication, and imaging clinically serious symptoms. Physical examination for scoliosis, functional leg length discrepancy, pain with lumbar movement, myofascial pain (paralumbar, piriformis, tensor fasciae latae (TFL)), regional bone pain (sacroiliac joint (SIJ), hip, vertebral body), and fibromyalgia. RESULTS: Scoliosis was prevalent in those with (77.5%) and without pain (60.0%), but prevalence of SIJ pain (84% vs 5%), fibromyalgia tender points (19% vs 0%), myofascial pain (96% vs 10%), and hip pain (48% vs 0%) was significantly different between groups (P < .001). Interrater reliability was excellent for SIJ pain (0.81), number of fibromyalgia tender points (0.84), and TFL pain (0.81); good for scoliosis (0.43), kyphosis (0.66), lumbar movement pain (0.75), piriformis pain (0.71), and hip disease by internal rotation (0.56); and marginal for leg length (0.00) and paravertebral pain (0.39). CONCLUSION: Biomechanical and soft tissue pathologies are common in older adults with CLBP, and many can be assessed reliably using a brief physical examination. Their recognition may save unnecessary healthcare expenditure and patient suffering. 40 PMID- 16318995 AU - Wik G, Fischer H, Finer B, Bragee B, Kristianson M, Fredrikson M TI - Retrospenial cortical deactivation during painful stimulation of fibromyalgic pts.

Gustav.Wik@psyk.uib.no AB - To study fibromyalgic pain this article contrasts positron emission tomographic measures of regional cerebral blood flow (rCBF) during externally induced acute pain and rest in eight fibromyalgia syndrome patients. An expected pattern of frontal and parietal cortical activation during acute pain as compared to rest was observed. However, reduced rCBF was additionally found in the retrosplenial cortex during acute pain as compared to rest. This may reflect that externally induced pain inhibits fibromyalgic pain and syndrome-related evaluative processes located in the retrosplenial cortex, and that fibromyalgic pain results from exaggerated attention to sub-noxious pain signaling, that is, secondary hyperalgesia. 41 PMID- 16357736 AU - Adak B, Tekeoglu I, Ediz L, Budancamanak M, Yazgan T, Karahocagil K, Demirel A TI - FM frequency in hepatitis B carriers.

AB - BACKGROUND: Fibromyalgia (FM) is characterized by diffuse musculoskeletal pain, fatigue, morning stiffness, and sleep disturbance. Chronic viral infections may trigger FM symptoms. OBJECTIVES: In this study, we aimed to evaluate whether there was an association between HBsAg seropositivity and fibromyalgia syndrome. METHODS: Fifty hepatitis B carriers (HBsAg positivity and anti-HBs negativity in sera for at least 6 months) and 50 age- and sex-matched HbsAg-negative control subjects were enrolled in this study. The hepatitis B carriers with normal or slightly elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were recruited from the infectious diseases outpatient clinic and the control group was recruited from the physical medicine and rehabilitation outpatient clinic. The relationship between groups was calculated by independent Student t test, chi-squared test, and Fisher exact test for comparing proportions. Alpha criterion for significance was set at P < 0.05. RESULTS: There was no statistically significant difference between the groups according to sex, mean age, body mass index, serum ALT, and AST levels (P > 0.05). FM syndrome and FM-associated symptoms were much more prevalent in the hepatitis B group (P < 0.001). CONCLUSION: The present study suggests that chronic hepatitis B carriage appears to increase the risk of FM and many of the typically associated symptoms. Whether this association is related to altered liver function, viral infection, concerns associated with chronic disease, or other factors, physicians should be aware of this apparent association. 42 PMID- 16012064 AU - Adams N, Sim J TI - Rehabilitation approaches in FM.

IN - Centre for Research in Health Care, Liverpool John Moores U, Great Crosshall Street, Liverpool, UK. j.sim@keele.ac.uk AB - PURPOSE: This paper provides an overview of the evidence for the principal approaches taken to the rehabilitation of patients with fibromyalgia (FM): exercise, psychologically-based approaches, multimodal approaches, self-management approaches, and complementary and alternative therapies. METHOD: A review of current published evidence. RESULTS: Owing to factors such as methodological shortcomings of existing studies, and the lack of evidence on individual modalities, it is difficult to draw definitive conclusions as to which is the most appropriate rehabilitation approach in FM. However, there is growing evidence for the role of exercise training, and clear indications that if appropriately prescribed, this can be undertaken without adverse effects. Similarly, psychologically-based interventions such as cognitive-behavioural therapy have received some support from the literature. Evidence for other interventions is more equivocal. CONCLUSIONS: It appears that a combination of interventions, in a multimodal approach (e.g., exercises combined with education and psychologically-based interventions) is the most promising means of managing patients with FM. 43 PMID- 15898360 AU - Adiels AM, Helkimo M, Magnusson T TI - Tactile stimulation as a complementary Rx of temporomandibular disorders in pts w FM syndrome.

IN - D o Stomatognathic Physiology, The Inst for Postgraduate Dental Education, Jonkoping, Sweden. anne-marie.adiels@vgregion.se AB - Pain of long duration is a common suffering in modern man. One such pain condition is fibromyalgia syndrome (FMS). Opinions about what treatment regimen that are to be used in these patients are diverging, and many of the treatments suggested are not, or only poorly, scientifically investigated. The aim of this pilot investigation was to evaluate if FMS patients with signs and symptoms of temporomandibular disorders (TMDs) refractory to conservative TMD treatment would respond positively to tactile stimulation in respect of local and/or general symptoms.Ten female patients fulfilling the inclusion criteria received such treatment once a week during a 10-week period. At the end of treatment, a positive effect on both clinical signs and subjective symptoms of TMD, as well as on general body pain, was registered. Eight out of 10 patients also perceived an improved quality of their sleep. At follow-ups after 3 and 6 months some relapse of both signs and symptoms could be seen, but there was still an improvement compared to the initial degree of local and general complaints. At the 6-months follow-up, half of the patients also reported a lasting improvement of their sleep quality. One hypothetical explanation to the positive treatment effect experienced by the tactile stimulation might be the resulting improvement of the patients' quality of sleep leading to increased serotonin levels. The results of the present pilot study are so encouraging that they warrant an extended, controlled study. 44 PMID- 15639063 AU - Adler GK, Geenen R TI - Hypothalamic-pituitary-adrenal & autonomic nervous system functioning in FM.

AB - OBJECTIVE: To ascertain the association between fibromyalgia (FM) tender points (TP) and health status in patients with systemic lupus erythematosus (SLE). METHODS: We performed a cross-sectional study of 173 SLE patients enrolled in the Hopkins Lupus Cohort. Patients were examined for FM TP and asked to complete the Health Assessment Questionnaire (HAQ) at the same visit. RESULTS: We found 38.2% of patients had no TP, 44.5% had 1-10 TP, and 17.3% had > or = 11 TP. No significant association was found between the number of FM TP and age, sex, race, or level of education. The mean score of the HAQ was 1.3 +/- 0.4. There were significant associations between FM TP and HAQ (no TP 1.1 +/- 0.3, 1-10 TP 1.4 +/- 0.4, > or = 11 TP 1.6 +/- 0.6; p = 0.0001). CONCLUSION: A strong association between the number of FM TP and health status was found in patients with SLE. The number of TP, and not just the presence/absence of FM, is associated with health status in SLE. 46 PMID- 14986061 AU - Alanoglu E, Ulas UH, Ozdag F, Odabasi Z, Cakci A, Vural O TI - Auditory event-related brain potentials in FM syndrome.

METHODS: The P300 component of ERP was studied in 36 female FMS patients and 22 control subjects. The short form 36 (SF-36) medical outcome study was used to determine quality of life. Number of tender points and disease duration were noted. Cognitive functions were evaluated with P300. RESULTS: The symptoms were discrepant in FMS (P<0.001). The scores of the eight SF-36 subgroups in FMS patients were significantly lower than in the control group (P<0.001). Fibromyalgia syndrome patients had prolonged latency and reduced amplitude of P300 (P<0.001). No correlation was found between the subgroups of SF-36, tender point count, disease duration, and P300. CONCLUSION: The results of our study reveal that FMS affects quality of life and dysfunction in cognitive abilities can be determined by brain event-related potentials. 47 PMID- 15820381 AU - Anthony KK, Schanberg LE TI - Pediatric pain syndromes & management of pain in children & adolescents w rheumatic disease.

Patients (90% Caucasian; mean age, 49.6 years; 26% with current major depressive disorder) received duloxetine 60 mg once daily (QD) (N=118), duloxetine 60 mg twice daily (BID) (N=116), or placebo (N=120). The primary outcome was the Brief Pain Inventory average pain severity score. Response to treatment was defined as >or=30% reduction in this score. Compared with placebo, both duloxetine-treated groups improved significantly more (P<0.001) on the Brief Pain Inventory average pain severity score. A significantly higher percentage of duloxetine-treated patients had a decrease of >or=30% in this score (duloxetine 60 mg QD (55%; P<0.001); duloxetine 60 mg BID (54%; P=0.002); placebo (33%)). The treatment effect of duloxetine on pain reduction was independent of the effect on mood and the presence of major depressive disorder. Compared with patients on placebo, patients treated with duloxetine 60 mg QD or duloxetine 60 mg BID had significantly greater improvement in remaining Brief Pain Inventory pain severity and interference scores, Fibromyalgia Impact Questionnaire, Clinical Global Impression of Severity, Patient Global Impression of Improvement, and several quality-of-life measures. Both doses of duloxetine were safely administered and well tolerated. In conclusion, both duloxetine 60 mg QD and duloxetine 60 mg BID were effective and safe in the treatment of fibromyalgia in female patients with or without major depressive disorder. 49 PMID- 16084464 AU - Asmundson GJ, Wright KD, Hadjistavropoulos HD TI - Hypervigilance & attentional fixedness in chr musculoskeletal pain: consistency of findings across modified stroop & dot-probe tasks.

IN - Faculty o Kinesiology & Health Studies, D o Psychology, U o Regina, Regina, Saskatchewan, Canada. gordon.asmundson@uregina.ca AB - Results from modified Stroop and dot-probe tasks have provided mixed evidence regarding attentional biases for sensory and affect pain stimuli in chronic pain patients. No studies have compared the same groups of chronic pain and healthy control participants on both tasks. We tested 36 patients with chronic musculoskeletal pain and 29 healthy control subjects on the modified Stroop and dot-probe tasks. Stimuli comprised affect pain, sensory pain, physical catastrophe, and neutral words. There was no evidence to suggest differential processing of threat cues by patients and control subjects on the modified Stroop task. All participants did, however, show differential processing of affect pain words. This was evident on both masked and unmasked presentation formats. There were no significant interactions between clinical status and threat word type observed for any of the indices of selective attention derived from the dot-probe task, but all participants had difficulty disengaging attention from affective pain and health catastrophe words. Findings were not influenced by individual differences in mood, anxiety, or fear of pain. Correlational analyses of the standard (unmasked) Stroop interference index and dot-probe indices of selective attention revealed a consistent lack of significant association, suggesting that the 2 tasks might be measuring different phenomena. Taken together, these findings provide evidence that chronic pain patients and healthy control participants do not differ in the way they attend to threatening linguistic stimuli. PERSPECTIVE: Some patients with chronic pain might have trouble paying attention to anything other than the affective components of pain and associated catastrophic health consequences. Interventions that specifically target this attentional fixedness might facilitate shifting attention to other targets and thereby reduce pain-specific anxiety and fear. 50 PMID- 15998750 AU - Assefi NP, Sherman KJ, Jacobsen C, Goldberg J, Smith WR, Buchwald D TI - A randomized clinical trial of acupuncture compared w sham acupuncture in FM. SO - Ann Intern Med. 2005 Jul 5;143(1):10-9. IN - The Group Health Cooperative Ctr for Health Studies, & U o Washington, Seattle, Washington, USA. AB - BACKGROUND: Fibromyalgia is a common chronic pain condition for which patients frequently use acupuncture. OBJECTIVE: To determine whether acupuncture relieves pain in fibromyalgia. DESIGN: Randomized, sham-controlled trial in which participants, data collection staff, and data analysts were blinded to treatment group. SETTING: Private acupuncture offices in the greater Seattle, Washington, metropolitan area. PATIENTS: 100 adults with fibromyalgia. INTERVENTION: Twice-weekly treatment for 12 weeks with an acupuncture program that was specifically designed to treat fibromyalgia, or 1 of 3 sham acupuncture treatments: acupuncture for an unrelated condition, needle insertion at nonacupoint locations, or noninsertive simulated acupuncture. MEASUREMENTS: The primary outcome was subjective pain as measured by a 10-cm visual analogue scale ranging from 0 (no pain) to 10 (worst pain ever). Measurements were obtained at baseline; 1, 4, 8, and 12 weeks of treatment; and 3 and 6 months after completion of treatment. Participant blinding and adverse effects were ascertained by self-report. The primary outcomes were evaluated by pooling the 3 sham-control groups and comparing them with the group that received acupuncture to treat fibromyalgia. RESULTS: The mean subjective pain rating among patients who received acupuncture for fibromyalgia did not differ from that in the pooled sham acupuncture group (mean between-group difference, 0.5 cm [95% CI, -0.3 cm to 1.2 cm]). Participant blinding was adequate throughout the trial, and no serious adverse effects were noted. LIMITATIONS: A prescription of acupuncture at fixed points may differ from acupuncture administered in clinical settings, in which therapy is individualized and often combined with herbal supplementation and other adjunctive measures. A usual-care comparison group was not studied. CONCLUSION: Acupuncture was no better than sham acupuncture at relieving pain in fibromyalgia. 51 PMID- 15982993 AU - Badawy AA, Morgan CJ, Llewelyn MB, Albuquerque SR, Farmer A TI - Heterogeneity of serum tryptophan concentration & availability to the brain in pts w the CFS.

Abdulla.Badawy@cardiffandvale.wales.n AB - We assessed the serotonin status of patients with the chronic fatigue syndrome (CFS). Tryptophan (Trp) availability to the brain, expressed as the ratio of concentration of serum Trp to the sum of those of its five competitors (CAA), and other parameters of Trp disposition were compared in 23 patients with the CFS and 42 healthy controls. The serum [free Trp]/[CAA] ratio was 43% higher in CFS patients, due to a 48% higher [free Trp]. [Total Trp] was also significantly higher (by 19%) in CFS patients, and, although the [total Trp]/[CAA] ratio did not differ significantly between the control and patient groups, the difference became significant when the results were co-varied with age and gender. [CAA] was not significantly different between groups, but was significantly lower in females, compared to males, of the CFS patient group. We have established normal ranges for Trp disposition parameters and propose criteria for defining the serotonin-biosynthetic status in humans. We have provisionally identified two subgroups of CFS patients, one with normal serotonin and the other with a high serotonin status. The relevance of our findings to, and their implications for, the pharmacological and other therapies of the chronic fatigue syndrome are discussed. 52 PMID- 16157056 AU - Baker K, Barkhuizen A TI - Pharmacologic Rx of FM.

Optimal treatment involves a multidisciplinary approach with a team of health care providers using pharmacologic and nonpharmacologic treatment. Because of the heterogeneity of the illness, management should be individualized for the patient. Pharmacologic treatment should address issues of pain control, sleep disturbance, fatigue, and any underlying coexisting mood disorder. Nonpharmacologic treatment should include patient education, a regular exercise and stretching program, and cognitive behavioral therapy. All of these are essential to improving functional capacity and quality of life. This review provides general guidelines in initiating a successful pharmacologic treatment program for patients with fibromyalgia. 53 PMID- 16321154 AU - Baraniuk JN, Casado B, Maibach H, Clauw DJ, Pannell LK, Hess S S TI - A CFS - related proteome in human cerebrospinal fluid.

Neurological dysfunction is common. We assessed cerebrospinal fluid to find proteins that were differentially expressed in this CFS-spectrum of illnesses compared to control subjects. METHODS: Cerebrospinal fluid specimens from 10 CFS, 10 PGI, and 10 control subjects (50 mul/subject) were pooled into one sample per group (cohort 1). Cohort 2 of 12 control and 9 CFS subjects had their fluids (200 mul/subject) assessed individually. After trypsin digestion, peptides were analyzed by capillary chromatography, quadrupole-time-of-flight mass spectrometry, peptide sequencing, bioinformatic protein identification, and statistical analysis. RESULTS: Pooled CFS and PGI samples shared 20 proteins that were not detectable in the pooled control sample (cohort 1 CFS-related proteome). Multilogistic regression analysis (GLM) of cohort 2 detected 10 proteins that were shared by CFS individuals and the cohort 1 CFS-related proteome, but were not detected in control samples. Detection of >or=1 of a select set of 5 CFS-related proteins predicted CFS status with 80% concordance (logistic model). The proteins were alpha-1-macroglobulin, amyloid precursor-like protein 1, keratin 16, orosomucoid 2 and pigment epithelium-derived factor. Overall, 62 of 115 proteins were newly described. CONCLUSION: This pilot study detected an identical set of central nervous system, innate immune and amyloidogenic proteins in cerebrospinal fluids from two independent cohorts of subjects with overlapping CFS, PGI and fibromyalgia. Although syndrome names and definitions were different, the proteome and presumed pathological mechanism(s) may be shared. 54 PMID- 15477496 AU - Baraniuk JN, Petrie KN, Le U, Tai CF, Park YJ, Yuta A, Ali M, Vandenbussche CJ, Nelson B TI - Neuropathology in rhinosinusitis.

Increasing strengths of HTS were sprayed into their nostrils at 5-minute intervals. Sensations of nasal pain, blockage, and drip increased with concentration and were significantly elevated above normal. These parallels suggested activation of similar subsets of afferent neurons. Urea and lysozyme secretion were dose dependent in all groups, suggesting that serous cell exocytosis was one source of urea after neural stimulation. Only AR and normal groups had mucin dose responses and correlations between symptoms and lysozyme secretion (R(2) = 0.12-0.23). The lysozyme dose responses may represent axon responses in these groups. The neurogenic stimulus did not alter albumin (vascular) exudation in any group. Albumin and mucin concentrations were correlated in sinusitis, suggesting that nonneurogenic factors predominated in sinusitis mucous hypersecretion. CFS had neural hypersensitivity (pain) but reduced serous cell secretion. HTS nasal provocations identified significant, unique patterns of neural and mucosal dysregulation in each rhinosinusitis syndrome. 55 PMID- 15947511 AU - Bazelmans E, Prins JB, Lulofs R, van der Meer JW, Bleijenberg G TI - Cognitive behaviour group therapy for CFS: a non-randomised waiting list controlled study.

E.Bazelmans@cukz.umcn.nl AB - BACKGROUND: It has been demonstrated that individual cognitive behaviour therapy is an effective treatment for chronic fatigue syndrome (CFS). The aim of the present study was to investigate the effectiveness of cognitive behaviour group therapy (CBGT) in an unselected group of CFS patients. Additionally, pretreatment characteristics of CFS patients who improve after CBGT were explored. METHODS: In a non-randomised waiting list controlled design, 31 patients were allocated to CBGT and 36 to the waiting list condition. CBGT consisted of 12 two-hour sessions during 6 months. Main outcome measures were fatigue (Checklist Individual Strength) and functional impairment (Sickness Impact Profile). RESULTS: A moderate effect on fatigue in favour of CBGT was found. For functional impairment, the effect was opposite to what was expected. Patients who improved after CBGT had less complaints at baseline compared to patients who did not improve. CONCLUSIONS: An explanation for the moderate effect might be that during CBGT, rest and relaxation were too much emphasised. Furthermore, an unselected group of CFS patients and therapists inexperienced in CB(G)T for CFS participated. Suggestions to improve CBGT for future research are given. 56 PMID- 16179967 AU - Beck CA, Patten SB, Williams JV, Wang JL, Currie SR, Maxwell CJ, El-Guebaly N TI - Antidepressant utilization in Canada.

IN - Dept. o Psychiatry, U o Calgary, Calgary, Alberta, Canada. cindy.beck@calgaryhealthregion.ca AB - OBJECTIVE: Antidepressant utilization can be used as an indicator of appropriate treatment for major depression. The objective of this study was to characterize antidepressant utilization in Canada, including the relationships of antidepressant use with sociodemographic variables, past-year and lifetime depression, number of past depressive episodes, and other possible indications for antidepressants. METHOD: We examined data from the Canadian Community Health Survey (CCHS) Cycle 1.2. The CCHS was a nationally representative mental health survey (N=36,984) conducted in 2002 that included a diagnostic instrument for past-year and lifetime major depressive episodes and other psychiatric disorders and a record of past-year antidepressant use. RESULTS: Overall, 5.8% of Canadians were taking antidepressants, higher than the annual prevalence of major depressive episode (4.8%) in the survey. Among persons with a past-year major depressive episode, the frequency of antidepressant use was 40.4%. After application of adjustments for probable successful outcomes of treatment, the estimated frequency of antidepressant use for major depression was more than 50%. Frequency of antidepressant treatment among those with a history of depression but without a past-year episode increased with the number of previous episodes. Among those taking antidepressants over the past year, only 33.1% had had a past-year episode of major depression. Migraine, fibromyalgia, anxiety disorder, or past depression was present in more than 60% of those taking antidepressants without a past-year episode of depression. CONCLUSIONS: The CCHS results suggest that antidepressant use has increased substantially since the early 1990s, and also that these medications are employed extensively for indications other than depression. 57 PMID- 16385767 AU - Bell IR, Brooks AJ, Baldwin CM, Fernandez M, Figueredo AJ, Witten ML TI - JP-8 jet fuel exposure & divided attention test performance in 1991 Gulf War veterans. [FM] SO - Aviat Space Environ Med. 2005 Dec;76(12):1136-44. IN - Research Service, Southern Arizona VA Health Care System, USA. ibell@u.arizona.edu AB - INTRODUCTION: Previous research indicates that a large cohort of veterans from the 1991 Gulf War report polysymptomatic conditions. These syndromes often involve neurocognitive complaints, fatigue, and musculoskeletal symptoms, thus overlapping with civilian illnesses from low levels of environmental chemicals, chronic fatigue syndrome, and fibromyalgia. METHODS: To test for time-dependent changes over repeated intermittent exposures, we evaluated objective performance on a computerized visual divided attention test in chronically unhealthy Gulf War veterans (n = 22 ill with low-level chemical intolerance (CI); n = 24 ill without CI), healthy Gulf War veterans (n = 23), and healthy Gulf War era veterans (n = 20). Testing was done before and after each of three weekly, double blind, low-level JP-8 jet fuel or clean air sham exposure laboratory sessions, including acoustic startle stimuli. RESULTS: Unhealthy veterans receiving jet fuel had faster mean peripheral reaction times over sessions compared with unhealthy veterans receiving sham clean air exposures. Unhealthy Gulf veterans with CI exhibited faster post- vs. pre-session mean central reaction times compared with unhealthy Gulf veterans without CI. Findings were controlled for psychological distress variables. DISCUSSION: These data on unhealthy Gulf veterans show an acceleration of divided attention task performance over the course of repeated low-level JP-8 exposures. The present faster reaction times are consistent with rat neurobehavioral studies on environmental toxicant cross-sensitization and nonlinear dose-response patterns with stimulant drugs, as well as some previous civilian studies using other exposure agents. Together with previous research findings, the data suggest involvement of central nervous system dopaminergic pathways in affected Gulf veterans. 58 PMID- 15813284 AU - Bellanti JA, Sabra A, Castro HJ, Chavez JR, Malka-Rais J, de Inocencio JM TI - Are attention deficit hyperactivity disorder & CFS allergy related? what is FM? SO - Allergy Asthma Proc. 2005 Jan-Feb;26(1):19-28. IN - Departments o Pediatrics , Georgetown U Med Ctr, Washington, D.C. 20057, USA. AB - Despite the progress made in the field of allergy-immunology in recent years, there are a group of diseases that the allergist-immunologist may be called on to manage in which their precise etiologies have not been identified but that appear to be initiated or exacerbated by allergic mechanisms. Attention deficit hyperactivity disorder (ADHD), chronic fatigue syndrome (CFS), and fibromyalgia (FM) fall into this category of disorders. Although the precise etiology of ADHD still remains unknown, the most prevalent theory is that it represents a neurobiologically based developmental disability leading to inadequate production of the neurotransmitter dopamine. In patients with CFS, there appears to be a fundamental dysfunction of the neuroendocrine-immunological system with deficiencies of immunological and neurological function, which, together with chronic viral infection, may lead to a sequence of events responsible for the symptoms of this disorder. FM appears to be a variant of CFS with a predominance of hypothalamic pituitary axis dysfunction. The disorder is characterized by chronic widespread pain and the finding of 11/18 tender points on examination. Now, there is emerging evidence to suggest that adverse reactions to foods or food components also may be associated with behavioral disturbances that may play a role in each of these disorders. An understanding of the interactive responses involved in the neuroendocrine-immunological network is essential for a comprehension of the pathophysiology of ADHD, CFS, and FM and the role of allergies appears to be an important triggering event in each of the disorders. 59 PMID- 15710315 AU - Benbadis SR TI - A spell in the epilepsy clinic & a history of "chronic pain" or "FM" independently predict a Dx of psychogenic seizures.

We reviewed the records of all patients evaluated over 5 years in a single epilepsy clinic for refractory seizures who eventually underwent EEG/video monitoring. We designated two groups: (1) patients with a diagnosis of "fibromyalgia" or "chronic pain" and (2) patients who had a seizure during the visit, either in the waiting area or in the examining room. Of 36 patients with "fibromyalgia" or "chronic pain," 27 (75%) were found to have PNES. Of 13 patients who had a "seizure" during their clinic visit, 10 (75%) were found to have PNES. We conclude that each of these findings has a predictive value of 75%. 60 PMID- 16174485 AU - Bennett R TI - FM: present to future. SO - Curr Rheumatol Rep. 2005 Oct;7(5):371-6. IN - D o Med, Oregon Health & Science U, Portland, OR 97201, USA. bennetrob1@comcast.net AB - There has been a dramatic increase in our understanding of fibromyalgia throughout the past 14 years since the publication of the 1990 American College of Rheumatology classification criteria. Before 1990, and for most of the 20th century, fibromyalgia was considered to be predominantly a muscle disorder; now the critical abnormality is described as "central sensitization." However, central sensitization has to have an initial genesis and nociceptive stimuli from painful foci in muscle are increasingly recognized as being relevant to the development of fibromyalgia. Clinicians also recognize an association between the initiation of fibromyalgia and chronic psychologic stressors and inflammatory disorders. It has been more difficult to understand how two such apparently diverse events could affect central pain physiology. However, some clues are emerging from the role of diverse stimuli in activating glial cells and the role of disordered cytokine networks. Some predictions about future developments in fibromyalgia are ventured based on the current state of knowledge. 61 PMID- 16157062 AU - Bennett R TI - Growth hormone in musculoskeletal pain states.

It also plays an important role in cartilage growth and the attainment of normal bone mass. There is only one rheumatic disorder, namely acromegaly, in which abnormalities of growth hormone production play a major etiologic role. However, there is increasing appreciation that suboptimal growth hormone secretion, leading to a state of adult growth hormone deficiency, may occur in the setting of chronic inflammatory disease, chronic corticosteroid use, and fibromyalgia. Therefore, the evaluation and effective management of growth hormone oversecretion and undersecretion is relevant to practicing rheumatologists. 62 PMID- 16082646 AU - Bennett RM, Schein J, Kosinski MR, Hewitt DJ, Jordan DM, Rosenthal NR TI - Impact of FM pain on health-related quality of life before & after Rx w tramadol/acetaminophen.

IN - Oregon Health & Science U, Portland, OR 97239, USA. bennetro@ohsu.edu AB - OBJECTIVE: To assess health-related quality of life (HRQOL) in patients with moderate-to-severe fibromyalgia pain compared with the general population, and to assess the relationship between pain severity and HRQOL before and after treatment with an analgesic. METHODS: Data were obtained from a randomized, double-blind study of patients with moderate-to-severe fibromyalgia pain. Patients received either tramadol/acetaminophen or placebo 4 times/day as needed for 91 days. HRQOL was measured with the Short Form 36 Health Survey (SF-36) and the Fibromyalgia Impact Questionnaire (FIQ). Baseline HRQOL scores were compared with a national sample of noninstitutionalized adults and a sample of patients with impaired HRQOL due to congestive heart failure. Patients with fibromyalgia were divided into tertiles by change in pain severity, and SF-36 scores were compared across the tertiles. Mean changes in SF-36 and FIQ scores were compared between treatment groups. RESULTS: Patients with fibromyalgia scored lower than the US norm on all SF-36 scales (P < 0.0001) and lower than patients with congestive heart failure on most scales. More severe pain was associated with greater impairment of HRQOL compared with less severe pain (P < 0.0001). Patients in the highest tertile for improved pain severity had greater improvement in HRQOL scores than patients in the lower tertiles. Compared with patients who received placebo (n = 157), patients treated with tramadol/acetaminophen (n = 156) showed greater improvement on SF-36 physical functioning, role physical, bodily pain, and physical summary scales, as well as FIQ scales for ability to do job, pain, and stiffness (P < 0.01). CONCLUSION: Moderate-to-severe fibromyalgia pain significantly impairs HRQOL, and effective pain relief in these patients significantly increases HRQOL. 63 PMID- 16273800 AU - Bennett R TI - The FM Impact Questionnaire (FIQ): a review of its development, current version, operating characteristics & uses.

IN - D o Med (OP09), Oregon Health & Science U, Portland, OR 97329, USA. bennetrob1@comcast.net AB - The Fibromyalgia Impact Questionnaire (FIQ) was developed in the late 1980s by clinicians at Oregon Health & Science University in an attempt to capture the total spectrum of problems related to fibromyalgia and the responses to therapy. It was first published in 1991 and since that time has been extensively used as an index of therapeutic efficacy. Overall, it has been shown to have a credible construct validity, reliable test-retest characteristics and a good sensitivity in demonstrating therapeutic change. The original questionnaire was modified in 1997 and 2002, to reflect ongoing experience with the instrument and to clarify the scoring system. The latest version of the FIQ can be found at the web site of the Oregon Fibromyalgia Foundation (www.myalgia.com/FIQ/FIQ). The FIQ has now been translated into eight languages, and the translated versions have shown operating characteristics similar to the English version. 64 PMID- 15889950 AU - Bentler SE, Hartz AJ, Kuhn EM TI - Prospective observational study of Rxs for unexplained chr fatigue.

AB - BACKGROUND: Unexplained chronic fatigue is a frequent complaint in primary care. A prospective observational study design was used to evaluate whether certain commonly used therapies for unexplained chronic fatigue may be effective. METHOD: Subjects with unexplained chronic fatigue of unknown etiology for at least 6 months were recruited from the Wisconsin Chronic Fatigue Syndrome Association, primary care clinics, and community chronic fatigue syndrome presentations. The primary outcome measure was change in a 5-question fatigue score from 6 months to 2 years. Self-reported interventions tested included prescribed medications, non-prescribed supplements and herbs, lifestyle changes, alternative therapies, and psychological support. Linear regression analysis was used to test the association of each therapy with the outcome measure after adjusting for statistically significant prognostic factors. RESULTS: 155 subjects provided information on fatigue and treatments at baseline and follow-up. Of these subjects, 87% were female and 79% were middle-aged. The median duration of fatigue was 6.7 years. The percentage of users who found a treatment helpful was greatest for coenzyme Q10 (69% of 13 subjects), dehydroepiandrosterone (DHEA) (65% of 17 subjects), and ginseng (56% of 18 subjects). Treatments at 6 months that predicted subsequent fatigue improvement were vitamins (p = .08), vigorous exercise (p = .09), and yoga (p = .002). Magnesium (p = .002) and support groups (p = .06) were strongly associated with fatigue worsening from 6 months to 2 years. Yoga appeared to be most effective for subjects who did not have unclear thinking associated with the fatigue. CONCLUSION: Certain alternative therapies for unexplained chronic fatigue, especially yoga, deserve testing in randomized controlled trials. 65 PMID- 16012060 AU - Bergman S TI - Psychosocial aspects of chr widespread pain & FM. SO - Disabil Rehabil. 2005 Jun 17;27(12):675-83. IN - Research & Development Centre, Spenshult, Oskarstrom, Sweden. stefan.bergman@spenshult.se AB - PURPOSE: To study the impact on health status as measured by SF-36 in groups of subjects having chronic musculoskeletal pain with different degree of generalization: No chronic pain (NCP), chronic regional pain (CRP), chronic widespread pain (CWP), CWP with a stricter 'Manchester' definition (CWP-M), and clinically defined fibromyalgia (FM). The study also examines the association between psychosocial and lifestyle background variables, and these pain-groups. METHOD: A cross-sectional study with a postal survey to 3928 subjects, constituting a representative sample of the adult general population, followed by clinical examination in a selected group of subjects with CWP. CWP and FM were diagnosed according to ACR 1990 fibromyalgia criteria. Health status was measured by SF-36 Health Survey. RESULTS: Patients with CWP, CWP-M, and FM were found to present with more severe impairment of health status than the other two population groups. Several psychosocial factors, such as belonging to a lower socio-economic group, being an immigrant, living in a compromised housing area, having lower educational level, experiencing lower social support and having a family history of chronic pain, were associated with the populations with CWP and FM. CONCLUSIONS: The spectrum of impact on health and association to background variables, with respect to a stricter definition of CWP, indicates that these factors are important to attend to in the understanding and management of CWP and FM. 66 PMID- 15729611 AU - Bernatsky S, Dobkin PL, De Civita M, Penrod JR TI - Co-morbidity & physician use in FM.

AB - OBJECTIVE: To describe comorbidity in women with FM, and to examine the effects of different types of comorbidity on physician use. METHODS: Women (n = 180) with primary FM were evaluated at baseline and 6 months later for self-reported health resource use and covariates. Reported comorbidity was classified into 4 categories: medical, psychiatric, "functional", and unknown. The category for "functional" conditions included disorders that have been classified by previous authors as medically unexplained symptoms such as the irritable bowel and chronic fatigue syndromes. Logistic regression models were developed to examine associations between types of comorbidity and physician use. RESULTS: Comorbid conditions were reported by over 90% of the sample. Total number of comorbid complaints was associated with high number of physician visits. In logistic regression models (controlling for age, ethnicity, education, disability, pain, and psychological vulnerability) medical comorbidity was a much stronger determinant of high number of physician visits than was "functional" comorbidity. CONCLUSIONS: Comorbidity with other disorders, both functional and medical, was high in this sample. Medical and psychiatric comorbidity were stronger determinants of high physician use than "functional" comorbidity. 67 PMID- 16262574 AU - Bingol U, Altan L, Yurtkuran M TI - Low-power laser Rx for shoulder pain.

BACKGROUND DATA: Low-energy laser therapy has recently been popularized in the treatment of various rheumatologic, neurologic, and musculoskeletal disorders such as osteoarthritis, rheumatoid arthritis, fibromyalgia, carpal tunnel syndrome, rotator cuff tendinitis, and chronic back pain syndromes. METHODS: A total of 40 patients who applied to our clinic with shoulder pain and complied with the selection criteria were included in the study. The patients were randomly assigned into Group I (n = 20, laser treatment) and Group II (n = 20, control). In Group I, patients were given laser treatment and an exercise protocol for 10 sessions during a period of 2 weeks. Laser was applied over tuberculum majus and minus, bicipital groove, and anterior and posterior faces of the capsule, regardless of the existence of sensitivity, for 1 min at each location at each session with a frequency of 2000 Hz using a GaAs diode laser instrument (Roland Serie Elettronica Pagani, wavelength 904 nm, frequency range of 5-7000 Hz, and maximum peak power of 27 W, 50 W, or 27 x 4 W). In Group II, placebo laser and the same exercise protocol was given for the same period. Patients were evaluated according to the parameters of pain, palpation sensitivity, algometric sensitivity, and shoulder joint range of motion before and after treatment. RESULTS: Analysis of measurement results within each group showed a significant posttreatment improvement for some active and passive movements in both groups, and also for algometric sensitivity in Group I (p < 0.05-0.01). Posttreatment palpation sensitivity values showed improvement in 17 patients (85%) for Group I and six patients (30%) for Group II. Comparison between two groups showed superior results (p < 0.01 and p < 0.001) in Group I for the parameters of passive extension and palpation sensitivity but no significant difference for other parameters. CONCLUSIONS: The results of our study have shown better results in palpation sensitivity and passive extension, but no significant improvement in pain, active range, and algometric sensitivity in laser treatment group compared to the control group in the patients with shoulder pain. 68 PMID- 15694694 AU - Blanco LE, de Serres FJ, Fernandez-Bustillo E, Kassam DA, Arbesu D, Rodriguez C, Torre JC TI - alpha1-Antitrypsin & FM: new data in favour of the inflammatory hypothesis of FM.

IN - D o Internal Med, Hosp Valle del Nalon, 33920 Riano-Langreo, Principado de Asturias, Spain. ignacio.blanco@sespa.princast.es AB - alpha1-Antitrypsin (AAT) circulates in high serum concentrations, and impregnates most body tissues. AAT has a broad anti-inflammatory spectrum, and modulates most inflammatory reactions occurring in human body. Recently, a possible relationship between AAT deficiency (AAT-D) and fibromyalgia (FM) has been raised, with the finding that intravenous infusions of purified human AAT efficiently controlled FM symptoms in two patients with severe hereditary AAT-D. On the other hand, functional magnetic resonance imaging has detected a significant greater activity in pain sensitive areas of the brain in patients with FM, in response to cutaneous stimuli, providing further evidence for a physiological explanation for FM pain. In recent studies abnormal profiles of inflammation markers in serum and biopsies have been found in FM patients. Since most of these inflammation mediators can be inhibited by AAT, these observations would suggest that at least a subset of the FM syndrome could be related to an inflammatory process, possibly due to an imbalance between inflammatory and anti-inflammatory substances, in the soft body tissues. Future directions of research would be: (1) to develop epidemiological studies to determine the gene frequency of AAT deficiency alleles in FM patients; (2) implementation of a double-blind placebo-controlled clinical trial to determine the specific role of AAT augmentation therapy in AAT-D patients with FM; (3) identification of specific laboratory markers for diagnostic and clinical evaluation purposes in FM; (4) application of the newest medical imaging techniques for diagnosis; and (5) identification of genetic, familial, and environmental risk factors suspected to participate in the FM syndrome development. 69 PMID- 16173250 AU - Blotman F, Thomas E, Myon E, Andre E, Caubere JP, Taieb C TI - Awareness & knowledge of FM among French rheumatologists & general practitioners.

IN - Rheumatology D, Lapeyronie Hosp, Montpellier, France. francis.blotman@wanadoo.fr AB - OBJECTIVES: Fibromyalgia is a chronic disorder characterized by widespread musculoskeletal pain and fatigue. Its prevalence is estimated to be at 3.4% in women and 0.5% in men. It is a major cause of morbidity. Our objective was to evaluate, using a self-questionnaire sent by mail, the level of knowledge of French physicians, general practitioners, and rheumatologists on fibromyalgia and to analyse their therapeutic approach. METHODS: The demographic characteristics of a sample of general practitioners and rheumatologists were compared to those of the overall data available. This comparison demonstrated the good representativeness of our sample. RESULTS: Fibromyalgia was considered as a disease by 23% of rheumatologists and 33% of general practitioners. While on average, each rheumatologist followed 30 fibromyalgia patients, each general practitioner followed 6.1 patients (i.e., 2 to 5% of their practice's patient base). Among rheumatologists, 6.4% made no distinction between this disease and depression vs. 13.1% of general practitioners. The diagnosis of fibromyalgia was made based on tenderness that occurs in precise, localized areas of the body (trigger points) by 94% of rheumatologists and 79.1% of general practitioners. Of general practitioners and rheumatologists, 93.7% and 73.7% respectively, have not received any medical school training on fibromyalgia or chronic fatigue syndrome. CONCLUSION: Given the lack of medical school training and continuing professional education concerning fibromyalgia (rare use of pain rating scales, confusion in the classification of rheumatic diseases), there is an urgent need to initiate an explicit teaching effort on chronic pain, and on fibromyalgia in particular. 70 PMID- 15271773 AU - Boonen A, van den Heuvel R, van Tubergen A, Goossens M, Severens JL, van der Heijde D, van der Linden S TI - Large differences in cost of illness & wellbeing between pts w FM, chr low back pain, or AS.

METHODS: Patients with fibromyalgia, chronic low back pain (CLBP), and ankylosing spondylitis who were referred to a specialist and participated in three randomised trials completed a cost diary for the duration of the study, comprising direct medical and non-medical resource utilisation and inability to perform paid and unpaid work. Patients rated perceived wellbeing (0-100) at baseline. Univariate differences in costs between the groups were estimated by bootstrapping. Regression analyses assessed which variables, in addition to the condition, contributed to costs and wellbeing. RESULTS: 70 patients with fibromyalgia, 110 with chronic low back pain, and 111 with ankylosing spondylitis provided data for the cost analyses. Average annual disease related total societal costs per patient were 7813 euro for fibromyalgia, 8533 euro for CLBP, and 3205 euro for ankylosing spondylitis. Total costs were higher for fibromyalgia and CLBP than for ankylosing spondylitis, mainly because of cost of formal and informal care, aids and adaptations, and work days lost. Wellbeing was lower in fibromyalgia (mean, 48) and low back pain (mean, 42) than in ankylosing spondylitis (mean, 67). No variables other than diagnostic group contributed to differences in costs or wellbeing. CONCLUSIONS: In patients under the care of a specialist, there were marked differences in costs and wellbeing between those with fibromyalgia or CLBP and those with ankylosing spondylitis. In particular, direct non-medical costs and productivity costs were higher in fibromyalgia and CLBP. 71 PMID- 15805128 AU - Bowen J, Pheby D, Charlett A, McNulty C TI - CFS: a survey of GPs' attitudes & knowledge.

IN - Health Protection Agency Primary Care Unit, Gloucester, UK. jill.whiting@hpa.org.uk AB - BACKGROUND: GPs need evidence and guidance to help them diagnose and manage Chronic Fatigue Syndrome (CFS)/ME appropriately. OBJECTIVES: The aim of this survey was to obtain baseline data and identify the factors associated with GPs' attitudes to and knowledge of CFS/ME. The attitude of GPs to the condition is an important indicator of likely prognosis. METHODS: A postal questionnaire was sent to 1054 GPs served by Taunton, Bristol and Gloucester laboratories. GPs' attitudes to nine statements about CFS/ME were assessed and the factors associated with positive or negative responses were determined. Knowledge of the clinical features was also assessed. RESULTS: 811 GPs (77%) returned the questionnaire. 48% of GPs did not feel confident with making a diagnosis of CFS/ME and 41% did not feel confident in treatment. 72% of GPs accepted CFS/ME as a recognisable clinical entity and those GPs had significantly more positive attitudes. Three other key factors that were significantly, positively associated with GPs' attitudes were knowing someone socially with CFS/ME, being male and seeing more patients with the condition in the last year. CONCLUSION: Despite the publication of guidance for GPs on CFS/ME, confidence with making a diagnosis and management was found to be low. Educational initiatives and guidance for GPs should stress the importance of accepting CFS/ME as a recognisable clinical entity, as this is linked to having a positive attitude and could lead to improved confidence to make a diagnosis and treat CFS/ME patients. 72 PMID- 15788958 AU - Bracha HS, Ralston TC, Williams AE, Yamashita JM, Bracha AS TI - The clenching-grinding spectrum & fear circuitry disorders: clinical insights from the neuroscience/paleoanthropology interface.

Matsunaga Med Center, 1132 Bishop Street, Ste, 307, Honolulu, HI 96813, USA. H.Bracha@med.va.gov AB - This review discusses the clenching-grinding spectrum from the neuropsychiatric/neuroevolutionary perspective. In neuropsychiatry, signs of jaw clenching may be a useful objective marker for detecting or substantiating a self-report of current subjective emotional distress. Similarly, accelerated tooth wear may be an objective clinical sign for detecting, or substantiating, long-lasting anxiety. Clenching-grinding behaviors affect at least 8 percent of the population. We argue that during the early paleolithic environment of evolutionary adaptedness, jaw clenching was an adaptive trait because it rapidly strengthened the masseter and temporalis muscles, enabling a stronger, deeper and therefore more lethal bite in expectation of conflict (warfare) with conspecifics. Similarly, sharper incisors produced by teeth grinding may have served as weaponry during early human combat. We posit that alleles predisposing to fear-induced clenching-grinding were evolutionarily conserved in the human clade (lineage) since they remained adaptive for anatomically and mitochondrially modern humans (Homo sapiens) well into the mid-paleolithic. Clenching-grinding, sleep bruxism, myofacial pain, craniomaxillofacial musculoskeletal pain, temporomandibular disorders, oro-facial pain, and the fibromyalgia/chronic fatigue spectrum disorders are linked. A 2003 Cochrane meta-analysis concluded that dental procedures for the above spectrum disorders are not evidence based. There is a need for early detection of clenching-grinding in anxiety disorder clinics and for research into science-based interventions. Finally, research needs to examine the possible utility of incorporating physical signs into Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition posttraumatic stress disorder diagnostic criteria. One of the diagnostic criterion that may need to undergo a revision in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition is Criterion D (persistent fear-circuitry activation not present before the trauma). Grinding-induced incisor wear, and clenching-induced palpable masseter tenderness may be examples of such objective physical signs of persistent fear-circuitry activation (posttraumatic stress disorder Criterion D). 73 PMID- 15745615 AU - Bradley LA TI - Psychiatric comorbidity in FM.

The aim of this review is to enhance understanding of psychiatric disorders that, alone or in combination with other physiologic (eg, neuroendocrine dysfunction) and psychosocial factors (eg, poor coping skills), may contribute to abnormal pain sensitivity and other illness behaviors of individuals with fibromyalgia. The review first identifies the psychiatric comorbidities that are associated most often with fibromyalgia and tend to aggregate within families of individuals with this disorder. It then examines the literature regarding the extent to which psychiatric illness, environmental stressors, or other psychosocial factors may contribute to the development of fibromyalgia. The review also presents recent findings concerning the extent to which psychosocial factors may contribute to treatment-related outcomes in pain and other health status variables among patients with fibromyalgia. 74 PMID- 16173249 AU - Breuer GS, Orbach H, Elkayam O, Berkun Y, Paran D, Mates M, Nesher G TI - Perceived efficacy among pts of various methods of complementary alternative medicine for rheumatologic diseases.

AB - OBJECTIVE: The purpose of this cross-sectional survey was to obtain and analyze data on self-perceived efficacy of different types of complementary alternative medicine (CAM) by patients with various rheumatologic conditions. METHODS: Patients followed in rheumatology outpatient clinics were screened for the use of CAM. Patients reporting the use of CAM were asked to participate in face-to-face structured interviews, specifying the various CAM types they used, and grading their subjective impression of efficacy of each CAM type on a scale of 1-10. RESULTS: 350 consecutive patients were screened and 148 reported using CAM. In general, homeopathy and acupuncture were the most commonly used CAM types (44% and 41% of the CAM users, respectively). The mean number of different CAM methods used by a CAM user was 1.9 +/- 1.1. Patients with fibromyalgia used significantly more CAM methods (2.7 +/- 1.4, p = 0.005). On patients' self-perceived efficacy scale of 1-10, the mean score of the whole group was 5.3 +/- 3.2. Acupuncture and homeopathy achieved significantly higher self-perceived efficacy scores in CAM users with spondylo-arthropathies and osteoarthritis, respectively, when compared to some of the other disease groups. Satisfaction was lowest among CAM users with rheumatoid arthritis, vasculitis and connective tissue diseases. CONCLUSION: In general, CAM users were less than moderately satisfied with self-perceived-efficacy of CAM therapies. However efficacy of specific CAM methods differed significantly among patients in different disease groups. 75 PMID- 16012063 AU - Burckhardt CS TI - Educating pts: self-management approaches.

IN - Primary Care, School o Nursing, Oregon Health & Science U, Portland, Oregon, USA. burckhac@ohsu.edu AB - BACKGROUND: Most research and treatment of post-breast cancer chronic pain has focused on local or regional pain problems in the operated area. The purpose of this pilot study was to compare and contrast the pain characteristics, symptom impact, health status, and quality of life of post-breast cancer surgery women with regional chronic pain versus those with widespread chronic pain. METHODS: A cross-sectional, descriptive design compared two groups of women with chronic pain that began after surgery: regional pain (n = 11) and widespread pain (n = 12). Demographics, characteristics of the surgery, as well as standardized questionnaires that measured pain (Brief Pain Inventory (BPI), Short Form McGill Pain Questionnaire (MPQ-SF)), disease impact (Fibromyalgia Impact Questionnaire (FIQ), Functional Assessment of Cancer Therapy-Breast (FACT-B)), health status (Medical Outcomes Short Form (SF-36)) and quality of life (Quality of Life Scale (QOLS)) were gathered. RESULTS: There were no significant differences between the groups on any demographic or type of surgery variable. A majority of both groups described their pain as aching, tender, and sharp on the MPQ-SF. On the BPI, intensity of pain and pain interference were significantly higher in the widespread pain group. Differences between the two groups reached statistical significance on the FIQ total score as well as the FACT-B physical well-being, emotional well-being and breast concerns subscales. The SF-36 physical function, physical role, and body pain subscales were significantly lower in the widespread pain group. QOLS scores were lower in the widespread pain group, but did not reach statistical significance. CONCLUSION: This preliminary work suggests that the women in this study who experienced widespread pain after breast cancer surgery had significantly more severity of pain, pain impact and lower physical health status than those with regional pain. 77 PMID- 15943960 AU - Burwinkle T, Robinson JP, Turk DC TI - Fear of movement: factor structure of the tampa scale of kinesiophobia in pts w FM syndrome.

IN - D o Anesthesiology, U o Washington, Seattle, Washington 98195, USA. tburwinkle@aol.com AB - Chronic pain patients often report fears that movement will exacerbate their symptoms. The Tampa Scale of Kinesiophobia (TSK) was designed to assess fear of movement. Previous findings with the TSK showed inconsistent factor structures and varied measurement properties. The TSK was completed by a sample of 233 patients with fibromyalgia syndrome who were being evaluated for participation in a rehabilitation program. A principal components analysis initially derived a 5-factor solution. However, the factor structure accounted for less than 50% of the variance, and the internal consistency of the factors was below conventional standards (<0.70). A series of principal components analyses "forcing" different factor structures revealed that the best solution was a single factor solution that contained 4 of the original 17 TSK items, accounting for more than 50% of the variance with adequate internal consistency (alpha =0.71). Inspection of the content of these 4 items, however, suggests that this factor more likely represents catastrophic thinking, rather than fear of movement. Nevertheless, for patients with fibromyalgia syndrome, a 4-item TSK appears to retain the most acceptable factor solution while also maintaining adequate internal consistency. PERSPECTIVE: Although the TSK is one of the most commonly used measures of fear of movement, the present study using the TSK with a sample of patients with fibromyalgia syndrome suggests that the measurement properties of the TSK are problematic. Recommendations for use of the TSK are provided. 78 PMID- 15788956 AU - Buskila D, Neumann L, Press J TI - Genetic factors in neuromuscular pain. [FM] SO - CNS Spectr. 2005 Apr;10(4):281-4.

Recent evidence suggests that these syndromes may share heritable pathophysiologic features. Familial studies suggest that genetic and familial factors may play a role in the etiopathogenesis of these conditions. There is evidence that polymorphisms of genes in the serotoninergic and catecholaminergic systems are linked to the pathophysiology of FM and related conditions and are associated with personality traits. The precise role of genetic factors in the etiopathology of FM remains unknown, but it is likely that several genes are operating together to initiate this syndrome. Larger longitudinal studies are needed to better clarify the role of genetics in the development of FM. 80 PMID- 15699087 AU - Cairns R, Hotopf M TI - A systematic review describing the prognosis of CFS. SO - Occup Med (Lond). 2005 Jan;55(1):20-31. IN - D o Psychological Med, Inst o Psychiatry, London, UK. AB - AIM: To perform a systematic review of studies describing the prognosis of chronic fatigue (CF) and chronic fatigue syndrome (CFS) and to identify occupational outcomes from such studies. METHOD: A literature search was used to identify all studies describing the clinical follow-up of patients following a diagnosis of CF or CFS. The prognosis is described in terms of the proportion of individuals improved during the period of follow-up. Return to work, other medical illnesses and death as outcomes are also considered, as are variables which may influence prognosis. RESULTS: Twenty-eight articles met the inclusion criteria and, for the 14 studies of subjects meeting operational criteria for CFS, the median full recovery rate was 5% (range 0-31%) and the median proportion of patients who improved during follow-up was 39.5% (range 8-63%). Less fatigue severity at baseline, a sense of control over symptoms and not attributing illness to a physical cause were all associated with a good outcome. Return to work at follow-up ranged from 8 to 30% in the three studies that considered this outcome. CONCLUSIONS: Full recovery from untreated CFS is rare. The prognosis for an improvement in symptoms is less gloomy. This review looks at the course of CF/CFS without systematic intervention. However, there is increasing evidence for the effectiveness of cognitive behavioural and graded exercise therapies. Medical retirement should be postponed until a trial of such treatment has been given. 81 PMID- 15607706 AU - Casado B, Zanone C, Annovazzi L, Iadarola P, Whalen G, Baraniuk JN TI - Urinary electrophoretic profiles from CFS & CFS/FM pts: a pilot study for achieving their normalization.

Urine was collected from these subjects for two consecutive 24 h periods and aliquots were submitted to micellar electrokinetic chromatography (MEKC). To compensate for the differences in peak migration times, these were normalized from the 35 min duration of run to a 100-point scale, and each peak was assigned its normalized time measure. Peak heights were also normalized by dividing the mAU by that of the internal standard (creatinine) and multiplying by 100. MEKC with normalization for peak height and migration time generated comparable results within each of the patient groups. CFS/FM and CFS had significant differences in peaks compared to NC that may be of significance as biomarkers of illnesses. 82 PMID- 16357732 AU - Castro I, Barrantes F, Tuna M, Cabrera G, Garcia C, Recinos M, Espinoza LR, Garcia-Kutzbach A TI - Prevalence of abuse in FM & other rheumatic disorders at a specialized clinic in rheumatic diseases in Guatemala City. SO - J Clin Rheumatol. 2005 Jun;11(3):140-5. IN - Louisiana St U Health Sciences Ctr, New Orleans, Louisiana, USA. AB - BACKGROUND: The importance of past adverse experiences is increasingly recognized in patients with rheumatic disease. OBJECTIVE: The objective of this study was to study the association of physical, verbal, and sexual abuse in patients with rheumatic disorders as compared with healthy volunteers. METHODS: In this case-control study, 500 new patients attending an outpatient rheumatic clinic were interviewed from September 1, 1999, to August 31, 2001. A total of 187 patients with 3 diagnoses were selected: 58 had fibromyalgia (FM), 74 rheumatoid arthritis (RA), and 55 patients with soft tissue rheumatic disease (STRD). All selected patients were asked to complete a questionnaire designed to obtain information regarding demographics and history of verbal, physical, and sexual abuse. A group of 187 healthy control subjects were also included, matched for sex and age. RESULTS: The prevalence of abuse was significantly more common in the rheumatic disease group than in the control group (48.1% versus 15%, P < 0.001). The prevalence of abuse among the groups was as follows: 70.7% of patients with FM reported abuse (24.3% verbal, 60.9% physical, and 14.8% sexual), 35.1% of patients with RA had a history of abuse (42.3% verbal, 30.7% physical, and 0% sexual), whereas 41.8% of patients with STRD reported abuse (43.4% verbal, 43.4% physical, and 0% sexual). When comparing the 3 groups, patients with FM showed a higher prevalence of abuse (P < 0.05). The abuse was usually longstanding (range, 1-10 years), and most abusers were close family members. CONCLUSION: Abuse, both physical and psychologic, was significantly increased in our rheumatic disease population, especially in patients with FM. Further studies are needed to fully establish its role. Questions about abuse may provide important information relative to care of our patients. 83 PMID- 16254097 AU - Chia JK TI - The role of enterovirus in CFS. SO - J Clin Pathol. 2005 Nov;58(11):1126-32. IN - CEI Research Ctr, Torrance, CA 90505, USA. Chiiasann@pol.net AB - Two and a half decades after coining of the term chronic fatigue syndrome (CFS), the diagnosis of this illness is still symptom based and the aetiology remains elusive. Enteroviruses are well known causes of acute respiratory and gastrointestinal infections, with tropism for the central nervous system, muscles, and heart. Initial reports of chronic enteroviral infections causing debilitating symptoms in patients with CFS were met with skeptism, and had been largely forgotten for the past decade. Observations from in vitro experiments and from animal models clearly established a state of chronic persistence through the formation of double stranded RNA, similar to findings reported in muscle biopsies of patients with CFS. Recent evidence not only confirmed the earlier studies, but also clarified the pathogenic role of viral RNA through antiviral treatment. This review summarises the available experimental and clinical evidence that supports the role of enterovirus in chronic fatigue syndrome. 84 PMID- 16518973 AU - Chiowchanwisawakit P, Koolvisoot A, Ratanasuwan W, Suwanagool S TI - Prevalence of rheumatic disease in HIV infected Thai pts.

AB - OBJECTIVE: To determine the prevalence of rheumatic diseases in HIV-infected patients at Siriraj Hospital, Thailand. MATERIAL AND METHOD: 178 patients who attended the HIV-Clinic at Siriraj Hospital between November 2002 and February 2003 were examined for the presence of rheumatic diseases. Diagnosis of HIV infection was performed by ELISA and confirmed by partial agglutination testing. HIV-infected patients were classified according to the Centers for Disease Control (CDC) 1993 revised classification system. Standard criteria were used to classify the rheumatic diseases. RESULTS: 98 patients had rheumatic diseases. Seventy-seven patients were treated with antiretroviral drugs. Forty-nine patients had mechanical low back pain, twenty-four patients had arthralgia, nineteen patients had plantar fasciitis, eighteen patients had nonspecific myalgia, thirteen patients had fibromyalgia, and eleven patients had others. Arthralgia was associated significantly with Quadricept muscle wasting (p = 0.00001). Nonspecific myalgia was more likely to be associated with female (p = 0. 018) and less likely with use of antiretroviral therapy (p = 0.031). CONCLUSION: Rheumatic diseases were commonly found in HIV-infected patients. Arthralgia associated with wasting Quadricep muscle. Nonspecific myalgia was predominant in female and without antiretroviral drug treatment. 85 PMID- 16192099 AU - Christie D, Wilson C TI - CBT in paediatric & adolescent health settings: a review of practice-based evidence.

CBT has been extensively adapted for use with children and young people with session content and method of delivery modified to acknowledge developmental stage and ability. Current approaches emphasise the psychological management of the impact of symptoms of particular types of physical health difficulties and prevention of the development of psychological difficulties, as well as in the alleviation of procedurally related stress. The need for collaboration with families and other parts of a child's network is particularly relevant in the paediatric setting. This review describes what we have found helpful in our work and provides a road map of where to go to find out more about how to do more. General CBT approaches are described as well as examples of how CBT has been used specifically for procedural distress, diabetes, sickle cell disease, chronic pain and chronic fatigue. 86 PMID- 16093743 AU - Ciccone DS, Elliott DK, Chandler HK, Nayak S, Raphael KG TI - Sexual & physical abuse in women w FM syndrome: a test of the trauma hypothesis.

IN - D o Psychiatry, UMDNJ-New Jersey MS, Newark, NJ 07103, USA. cicconds@umdnj.edu AB - OBJECTIVES: According to the trauma hypothesis, women with fibromyalgia syndrome (FMS) are more likely to report a history of sexual and/or physical abuse than women without FMS. In this study, we rely on a community sample to test this hypothesis and the related prediction that women with FMS are more likely to have posttraumatic stress disorder than women without FMS. METHODS: Eligibility for the present study was limited to an existing community sample in which FMS and major depressive disorder were prevalent. The unique composition of the original sample allowed us to recruit women with and without FMS from the community. A total of 52 female participants were enrolled in the present FMS group and 53 in the control (no FMS) group. Sexual and physical abuse were assessed retrospectively using a standardized telephone interview. RESULTS: Except for rape, sexual and physical abuse were reported equally often by women in the FMS and control groups. Women who reported rape were 3.1 times more likely to have FMS than women who did not report rape (P<0.05). There was no evidence of increased childhood abuse in the FMS group. Women with FMS were more likely to have posttraumatic stress disorder symptoms (intrusive thoughts and arousal) as well as posttraumatic stress disorder diagnosis (P<0.01). DISCUSSION: With the exception of rape, no self-reported sexual or physical abuse event was associated with FMS in this community sample. In accord with the trauma hypothesis, however, posttraumatic stress disorder was more prevalent in the FMS group. Chronic stress in the form of posttraumatic stress disorder but not major depressive disorder may mediate the relationship between rape and FMS. 87 PMID- 16338194 AU - Cimbiz A, Bayazit V, Hallaceli H, Cavlak U TI - The effect of combined therapy (spa & physical therapy) on pain in various chr diseases.

IN - Dumlupinar U, Health Institution o Higher Education, D o Physical Therapy & Rehabilitation, Tanvanly Yolu, 43100 Kutahya, Turkey. alicimbizphd@hotmail.com AB - OBJECTIVE: Spa therapy is commonly used in the treatment of daily chronic diseases practice, but its benefits are still the subjects of discussion. This study investigates possible effects of a combined spa and physical therapy program on pain and hemodynamic responses in various chronic diseases. METHODS: The pain intensity and hemodynamic responses of 472 patients involved in a spa and physical therapy program were studied retrospectively. Assessment criteria were pain [Visual Analog Scale (VAS)] and hemodynamic responses (heart rate, blood pressure, respiratory rate). Assessments took place before, immediately after treatment, and after completion of the spa program (before discharge). RESULTS: The patients with ankle arthrosis, fibromyalgia and cervical disc herniation reported the highest VAS score before treatment program (P < 0.05). After the therapy program, VAS scores were seen to decrease compared to before treatment (P < 0.05). The patients with osteoarthritis of the hip (1.3+/-1.2) and soft tissue rheumatism (1.3+/-1.2) had the lowest VAS score before discharge compared to patients with other pathologies (P < 0.05). No statistically significant differences were detected between both sexes in terms of pain improvement (P > 0.05). On discharge, all hemodynamic responses decreased significantly compared to before and immediately after initiation of the therapy program (P < 0.01). CONCLUSION: To decrease pain and high blood pressure without hemodynamic risk, a combined of spa and physical therapy program may help to decrease pain and improve hemodynamic response in patients with irreversible pathologies. 88 PMID- 15755409 AU - Clark GT, Minakuchi H, Lotaif AC TI - Orofacial pain & sensory disorders in the elderly.

We assessed brain 5-HT1A receptor binding potential directly using the specific radioligand [11C]WAY-100635 and positron emission tomography (PET). METHODS: We selected 10 patients from a tertiary referral clinic who fulfilled the CDC consensus criteria for CFS. To assemble a homogenous group and avoid confounding effects, we enrolled only subjects who were completely medication-free and did not have current comorbid psychiatric illness. We also scanned 10 healthy control subjects. RESULTS: There was a widespread reduction in 5-HT1A receptor binding potential in CFS relative to control subjects. This was particularly marked in the hippocampus bilaterally, where a 23% reduction was observed. CONCLUSIONS: There is evidence of decreased 5-HT1A receptor number or affinity in CFS. This may be a primary feature of CFS, related to the underlying pathophysiology, or a finding secondary to other processes, such as previous depression, other biological changes or the behavioral consequences of CFS. 90 PMID- 16177595 AU - Cook DB, Nagelkirk PR, Peckerman A, Poluri A, Mores J, Natelson BH TI - Exercise & cognitive performance in CFS.

IN - U o Wisconsin-Madison, D o Kinesiology, USA. cookdb@njneuromed.org AB - PURPOSE: To determine the effect of submaximal steady-state exercise on cognitive performance in patients with chronic fatigue syndrome (CFS) alone, CFS with comorbid fibromyalgia FM (CFS + FM), and sedentary healthy controls (CON). METHODS: Twenty CFS-only patients, 19 CFS + FM, and 26 CON completed a battery of cognitive tests designed to assess speed of information processing, variability, and efficiency. Tests were performed at baseline, immediately before, and twice following 25 min of either cycle ergometry set at 40% of peak oxygen capacity or quiet rest. RESULTS: There were no group differences in average percentage of peak oxygen consumption during exercise (CFS = 45%; CFS + FM = 47%; Control = 43%: P = 0.2). There were no significant effects of acute exercise on cognitive performance for any group. At baseline, one-way ANOVA indicated that CFS patients displayed deficits in speed of processing, performance variability, and task efficiency during several cognitive tests compared with healthy controls. However, the CFS + FM patients were not different than controls. Repeated measures ANOVA indicated that across all tests (pre- and postexercise) CFS, but not CFS + FM, were significantly less consistent (F2,59 = 3.7, P = 0.03) and less efficient (F2,59 = 4.6, P = 0.01) than controls. CONCLUSION: CFS patients without comorbid FM exhibit subtle cognitive deficits in terms of speed, consistency, and efficiency that are not improved or exacerbated by light exercise. Importantly, our data suggest that CFS + FM patients do not exhibit cognitive deficits either pre- or postexercise. These results highlight the importance of disease heterogeneity in studies determining acute exercise and cognitive function in CFS. 91 PMID- 15818653 AU - Costa DD, Bernatsky S, Dritsa M, Clarke AE, Dasgupta K, Keshani A, Pineau C TI - Determinants of sleep quality in women w SLE. [FM] SO - Arthritis Rheum. 2005 Apr 15;53(2):272-8. IN - McGill U Health Centre, Montreal, Quebec, Canada. Deborah.DaCosta@mcgill.ca AB - OBJECTIVE: To characterize sleep complaints in women with systemic lupus erythematosus (SLE) and to identify correlates of sleep quality. METHODS: Sleep quality in 100 women with SLE was assessed using the Pittsburgh Sleep Quality Index (PSQI). Participants completed standardized questionnaires assessing depressed mood, leisure time physical activity, functional disability, and pain severity. A clinical examination determined disease activity, cumulative damage, and whether patients fulfilled the American College of Rheumatology criteria for fibromyalgia. A series of hierarchical multiple regressions were computed. RESULTS: The mean +/- SD global PSQI score was 6.98 +/- 4.03, with moderate to severe sleep impairment reported by 56% of the sample. The first model testing the importance of demographic factors was not statistically significant. In the disease-related model, the use of prednisone and functional disability both contributed to poor sleep quality (P < 0.001). The addition of level of exercise participation to the demographic set significantly added to the model (P = 0.001). Depression significantly added to the demographic set, explaining 29% of the variance (P < 0.0001). When these variables, along with disease related variables, were simultaneously regressed on the PSQI Global Score, only depressed mood appeared as a significant independent determinant of global sleep quality (P < 0.001). However, the point estimates for the Beta coefficients were consistent with effects for lack of exercise and prednisone use. CONCLUSION: A significant proportion of women with SLE suffer from poor sleep quality. The findings suggest that depressed mood, prednisone use, and lack of exercise contribute to decreased overall sleep quality. 92 PMID- 16029148 AU - Covelli V, Passeri ME, Leogrande D, Jirillo E, Amati L TI - Drug targets in stress-related disorders. [CGS] SO - Curr Med Chem. 2005;12(15):1801-9. IN - Division o Neurology, Polyclinic Hosp, Bari Italy. AB - Nervous and immune systems mutually cooperate via release of mediators of both neurological and immunological derivation. Adrenocorticotropin hormone (ACTH) is a product of the hypothalamus-pituitary adrenal axis (HPAA) which stimulates secretion of corticosteroids from adrenals. In turn, corticosteroids modulate the immune response in virtue of their anti-inflammatory activity. On the other hand, catecholamines, products of the sympathetic nervous system (SNS), regulate immune function by acting on specific beta-adrenergic receptors. Conversely, cytokines released by monocytes/macrophages and lymphocytes, upon antigenic stimulation, are able to cross the blood-brain-barrier, thus modulating nervous functions (e.g., thermoregulation, sleep, and appetite). However, cytokines are locally produced in the brain, especially in the hypothalamus, thus contributing to the development of anorexic, pyrogenic, somnogenic and behavioural effects. Besides pathogens and/or their products, the so-called stressors are able to activate both HPAA and SNS, thus influencing immune responses. In this respect, many studies conducted in medical students taking exams have evidenced an array of stress-induced immune alterations. Phobic disorders and migraine without aura (MWA) represent examples of stress-related disorders in which phagocytic immune deficits, endotoxemia and exaggerated levels of proinflammatory cytokines [Tumor Necrosis Factor-alpha (TNF- alpha), and interleukin- 1 beta] have been detected. Quite interestingly, administration of a thymic hormone could ameliorate clinical symptoms in phobic patients. In MWA patients, a beta-blocker, propranolol, could mitigate migraine, whose cessation coincided with a drop of TNF-alpha serum concentration. In phobic disorders and in MWA, benzodiazepines are very often administered and, in this respect, some of them, such as diazepam, inhibit immune functions, while others, e.g., alprazolam, enhance immune responses. Alprazolam could improve clinical symptoms in MWA patients. Chronic Fatigue Syndrome (CFS) is a disorder whose etiology and pathogenesis are still unknown. In this syndrome both abnormalities of nervous and immune systems have been reported. Despite many immune parameters evaluated in CFS no specific biomarkers of disease have been found. Our own data are in agreement with current literature in that we found decreased levels of serum (IFN)-gamma in these patients, thus indicating a predominance of T helper (h)1 response in CFS. Also leptin, a hormone which regulates food intake, fluctuates within normal ranges in CFS individuals. Quite interestingly, in depressed patients, used as controls, leptinaemia was more elevated than in CFS. Finally, in a series of recent therapeutic trials several immunomodulating agents have been used, such as staphypan Berna, lactic acid bacteria, kuibitang and intravenous immunoglobulin. In conclusion, it seems that major drug targets in stress-related disorders are immune cells in terms of inhibition of proinflammatory cytokines and modulation of Th responses. In particular, according to recent evidences, antidepressants seem to exert beneficial effects in experimental autoimmune neuritis in rats by decreasing IFN- beta release or augmenting NK activity in depressed patients. 93 PMID- 16078360 AU - Crofford LJ TI - The relationship of FM to neuropathic pain syndromes.

Deborah.DaCosta@mcgill.ca AB - OBJECTIVE: To determine the efficacy of a 12-week individualized home-based exercise programme on physical functioning, pain severity and psychological distress for women with fibromyalgia (FM). METHODS: Seventy-nine women with a primary diagnosis of FM were randomized to a 12-week individualized home-based moderate-intensity exercise programme or to a usual care control group. Outcomes were functional capacity (Fibromyalgia Impact Questionnaire), pain severity and psychological distress. Outcomes were measured at study entry, at the end of the 12-week intervention, and at 3 and 9 months following completion of the intervention. RESULTS: On the basis of intention-to-treat analyses, a significant improvement in functional capacity at 3 and 9 months following treatment for participants in the exercise group who were more functionally disabled at study entry was observed. At both 3 and 9 months post-treatment, the mean estimated benefit of the intervention was more than 10 points [-12.3 (95% CI, -21.9 to -2.8); -10.8 (95% CI, -21.5 to -0.2)]. Compared with the control group, statistically significant improvements in upper body pain were evident in the exercise group at post-treatment. These between-group differences in upper body pain were maintained at 3 and 9 months post-treatment. No statistically significant group differences on lower body pain and psychological distress were found. CONCLUSIONS: Home-based exercise, a relatively low-cost treatment modality, has the potential to improve important health outcomes in FM. 96 PMID- 16282040 AU - Dadabhoy D, Clauw DJ TI - FM: progress in Dx & Rx.

Diagnosis and treatment have been especially challenging due to limited knowledge of etiology and poor response to conventional treatment of pain. Appreciation for the interactions of neurobiologic, psychologic, and behavioral factors in the disease pathogenesis has led to improved treatment options that can be effective in individual patients. Current evidence advocates a multifaceted program emphasizing patient education, medications for improving symptoms, and aggressive use of exercise and cognitive-behavioral approaches to retain or restore function. 97 PMID- 15802694 AU - Darbishire L, Seed P, Ridsdale L TI - Predictors of outcome following Rx for chr fatigue.

In common with other chronic and contested conditions such as Chronic Fatigue Syndrome, phobias are stigmatised and subjected to widespread judgmental attitudes in both medical and lay populations. In contrast, however, phobic experience is rarely characterised by difficulty in describing symptoms and obtaining a diagnosis: core fearful reaction to and avoidance of particular objects is usually obvious and uncontested. The crucial difference is that phobias are constituted by emotions and behaviours considered irrational and inconsequential, and it is their (perceived absence of) significance that raises questions and eyebrows. In other words, what does it matter and who cares if you happen to be scared of snakes? Using phobics' own words as far as possible, the paper explores the processes through which phobic emotions are constructed as contested, and examines phobic means of managing experience and perception of these emotions. It reveals that many respondents are resourceful and resistant, continually renegotiating their positioning as irrational, incapable and emotionally weak. 99 PMID- 15955487 AU - de Lange FP, Kalkman JS, Bleijenberg G, Hagoort P, van der Meer JW, Toni I TI - Gray matter volume reduction in the CFS.

Donders Centre for Cognitive Neuroimaging, Radboud U Nijmegen, NL-6500 HB Nijmegen, The Netherlands. floris.delange@fcdonders.ru.nl AB - The chronic fatigue syndrome (CFS) is a disabling disorder of unknown etiology. The symptomatology of CFS (central fatigue, impaired concentration, attention and memory) suggests that this disorder could be related to alterations at the level of the central nervous system. In this study, we have used an automated and unbiased morphometric technique to test whether CFS patients display structural cerebral abnormalities. We mapped structural cerebral morphology and volume in two cohorts of CFS patients (in total 28 patients) and healthy controls (in total 28 controls) from high-resolution structural magnetic resonance images, using voxel-based morphometry. Additionally, we recorded physical activity levels to explore the relation between severity of CFS symptoms and cerebral abnormalities. We observed significant reductions in global gray matter volume in both cohorts of CFS patients, as compared to matched control participants. Moreover, the decline in gray matter volume was linked to the reduction in physical activity, a core aspect of CFS. These findings suggest that the central nervous system plays a key role in the pathophysiology of CFS and point to a new objective and quantitative tool for clinical diagnosis of this disabling disorder. 100 PMID- 16084221 AU - Denko CW, Malemud CJ TI - Role of the growth hormone/insulin-like growth factor-1 paracrine axis in rheumatic diseases. [FM] SO - Semin Arthritis Rheum. 2005 Aug;35(1):24-34. IN - Case Western Reserve U School o Med, Cleveland, Ohio 44106, USA. AB - OBJECTIVES: Hypothalamic-pituitary axis abnormalities have been associated with systemic disturbances in several rheumatic diseases. Longitudinal analysis of erythrocyte, serum, urinary and synovial fluid growth hormone (GH), insulin-like growth factor-1 (IGF-1), and somatostatin levels could provide important surrogate measures of disease activity in rheumatic diseases. METHODS: The authors reviewed the population and longitudinal studies literature on GH, IGF-1, and somatostatin levels in rheumatic disorders using the PubMed and Medlines databases from the National Library of Medicine. In addition to the literature search, primary data were analyzed for basal somatostatin levels in patients with hand, knee, and spine osteoarthritis (OA) as well as primary and secondary hip OA. RESULTS: A review of the literature supports the view that hypothalamic-pituitary axis dysfunction accompanies clinical symptoms in many rheumatic diseases. In studies from our laboratory, serum GH levels were elevated in patients with OA, rheumatoid arthritis (RA), fibromyalgia, and diffuse idiopathic skeletal hyperostosis but not in patients with gout, pseudogout, or systemic lupus erythematosus. In OA and RA, synovial fluid GH levels exceeded serum GH levels. However, the literature remains controversial regarding the significance of changes in IGF-1 levels in rheumatic disorders. Many studies support an inverse relationship between age and IGF-1. Elevated serum GH levels in various rheumatic diseases were not coupled to changes in serum IGF-1 in diffuse idiopathic skeletal hyperostosis, RA, and fibromyalgia. In particular, serum IGF-1 levels in OA were shown to be lower or no different compared with age-matched normal subjects. Further, in OA, impaired articular chondrocyte response to IGF-1 was attributed, in part, to low synovial fluid IGF-1 that further compromised IGF-1 chondrocyte responses as a result of increased levels of synovial fluid IGF-1 binding proteins. Of note, serum somatostatin levels and "specific" somatostatin receptor levels were often lower in RA and systemic lupus erythematosus, but basal serum somatostatin levels were generally not altered in OA. CONCLUSIONS: The results of these analyses support the view that some rheumatic diseases such as OA and diffuse idiopathic skeletal hyperostosis, heretofore considered to be purely focal and degenerative, could be reclassified as systemic metabolic disturbances. We propose that serum GH, IGF-1, and somatostatin levels be monitored on a longitudinal basis during the course of medical therapy of rheumatic diseases to determine the extent to which changes in clinical symptoms (exemplified by reduced pain and inflammation and improved range of joint motion) are accompanied by changes in the basal concentration of these hypothalamic/pituitary-related hormones. 101 PMID- 15759159 AU - Denko CW, Malemud CJ TI - Serum growth hormone & insulin but not insulin-like growth factor-1 levels are elevated in pts w FM syndrome.

AB - Standard radioimmunoassay (RIA) was employed to quantify basal serum growth hormone (GH), insulin-like growth factor-I (IGF-1), and insulin levels in 32 normoglycemic patients with clinically active fibromyalgia and in 29 normoglycemic control subjects. The GH concentration was significantly higher (P < 0.001) in female fibromyalgia patients than age-matched, normal female subjects. In contrast, basal serum IGF-1 concentrations did not differ between these groups. A scatter plot generated from two-stage, least-squares analysis showed that serum GH lacked correlation with the serum IGF-1 concentrations of normal female subjects (P = 0.73) and female fibromyalgia patients (P = 0.19). In addition to the results from serum GH and IGF-1 RIA, we also found significantly higher fasting serum insulin levels (P = 0.03) in male fibromyalgia patients and a trend toward elevated fasting serum insulin levels in the female fibromyalgia population ( P = 0.07), with the mean fasting level in the male fibromyalgia group (35.7 microU/ml(-1)) exceeding the upper limit of normal serum insulin levels (i.e., 27 microU/ml(-1)). Based on these results, basal serum GH and fasting serum insulin levels appear to be valuable surrogate markers in clinically active, normoglycemic fibromyalgia patients. 102 PMID- 16056170 AU - DiNucci EM TI - Energy healing: a complementary Rx for orthopaedic & other conditions. SO - Orthop Nurs. 2005 Jul-Aug;24(4):259-69. IN - Stanford U, Stanford, CA, USA. AB - Complementary and alternative therapies continue to grow in popularity among healthcare consumers. Among those modalities is energy healing (EH) (Eisenberg et al., 1998). EH is an adjunctive treatment that is noninvasive and poses little downside risk to patients. Well more than 50 major hospitals and clinics throughout the United States offer EH to patients (DiNucci, research table on healthcare facilities that offer Reiki, unpublished data, 2002). The National Institutes of Health is funding numerous EH studies that are examining its effects on a variety of conditions, including temporomandibular joint disorders, wrist fractures, cardiovascular health, cancer, wound healing, neonatal stress, pain, fibromyalgia, and AIDS (National Institutes of Health, 2004a). Several well-designed studies to date show significant outcomes for such conditions as wound healing (Grad, 1965) and advanced AIDS (Sicher, Targ, Moore, & Smith, 1998), and positive results for pain and anxiety (Aetna IntelliHealth, 2003a; Wardell, Weymouth, 2004), among others (Gallob, 2003). It is also suggested that EH may have positive effects on various orthopaedic conditions, including fracture healing, arthritis, and muscle and connective tissue (Prestwood, 2003). Because negative outcomes risk is at or near zero throughout the literature, EH is a candidate for use on many medical conditions. 103 PMID- 16208640 AU - Dobkin PL, Abrahamowicz M, Fitzcharles MA, Dritsa M, da Costa D TI - Maintenance of exercise in women w FM.

IN - The McGill U Health Centre, McGill University, Montreal, Quebec, Canada. patricia.dobkin@mcgill.ca AB - OBJECTIVE: To identify predictors of maintenance of exercise for women with fibromyalgia (FM). METHODS: Women with FM who had been randomized to the exercise arm of a clinical trial were studied prospectively during and 3 months following treatment. Subjects completed exercise logs weekly and returned the data via postal mail. Outcome variables were duration of aerobic and stretching exercises. Two separate multivariate models for longitudinal data were built with adjustment for in-treatment adherence and time. Pretreatment characteristics (self efficacy, pain, disability, stress, exercise barriers and benefits, and age) and changes during treatment (pain, disability, stress, and exercise barriers and benefits) were considered potential predictors of exercise maintenance. RESULTS: Stretching significantly decreased in the 3 months following treatment. High stress at baseline and increases in stress during treatment were associated with poor maintenance of stretching. Disability at baseline (measured with the Fibromyalgia Impact Questionnaire), an increase in barriers to exercise during treatment, and increases in upper-body pain during treatment were associated with worse maintenance of aerobic exercise in the 3 months following treatment. CONCLUSION: The maintenance of an exercise program in women with FM appears to be contingent on being able to deal with stress, pain, barriers to exercise, and disability. 104 PMID- 16076658 AU - Doljansky JT, Kannety H, Dagan Y TI - Working under daylight intensity lamp: an occupational risk for developing circadian rhythm sleep disorder? [CFS] SO - Chronobiol Int. 2005;22(3):597-605. IN - The Inst for Sleep & Fatigue Med, Chaim Sheba Health Ctr, Tel-Hashomer, Israel. Julia.Tamir@Sheba.health.gov.il AB - A 47-yr-old male was admitted to the Institute for Fatigue and Sleep Medicine complaining of severe fatigue and daytime sleepiness. His medical history included diagnosis of depression and chronic fatigue syndrome. Antidepressant drugs failed to improve his condition. He described a gradual evolvement of an irregular sleep-wake pattern within the past 20 yrs, causing marked distress and severe impairment of daily functioning. He had to change to a part-time position 7 yrs ago, because he was unable to maintain a regular full-time job schedule. A 10-day actigraphic record revealed an irregular sleep-wake pattern with extensive day-to-day variability in sleep onset time and sleep duration, and a 36 h sampling of both melatonin level and oral temperature (12 samples, once every 3 h) showed abnormal patterns, with the melatonin peak around noon and oral temperature peak around dawn. Thus, the patient was diagnosed as suffering from irregular sleep-wake pattern. Treatment with melatonin (5 mg, 2 h before bedtime) did not improve his condition. A further investigation of the patient's daily habits and environmental conditions revealed two important facts. First, his occupation required work under a daylight intensity lamp (professional diamond-grading equipment of more than 8000 lux), and second, since the patient tended to work late, the exposure to bright light occurred mostly at night. To recover his circadian rhythmicity and stabilize his sleep-wake pattern, we recommended combined treatment consisting of evening melatonin ingestion combined with morning (09:00 h) bright light therapy (0800 lux for 1 h) plus the avoidance of bright light in the evening. Another 10-day actigraphic study done only 1 wk after initiating the combined treatment protocol revealed stabilization of the sleep-wake pattern with advancement of sleep phase. In addition, the patient reported profound improvement in maintaining wakefulness during the day. This case study shows that chronic exposure to bright light at the wrong biological time, during the nighttime, may have serious effects on the circadian sleep-wake patterns and circadian time structure. Therefore, night bright light exposure must be considered to be a risk factor of previously unrecognized occupational diseases of altered circadian time structure manifested as irregularity of the 24 h sleep-wake cycle and melancholy. 105 PMID- 15817039 AU - Driver C TI - An under-active or over-active internal world? An exploration of parallel dynamics within psyche & soma, & the difficulty of internal regulation, in pts w CFS & ME. SO - J Anal Psychol. 2005 Apr;50(2):155-73. AB - This paper explores the dynamics brought into analytic work when there is a symmetric fusion between psyche and soma within the patient. It will consider how such a fusion may emerge from reverberations between physical constitution and a lack of maternal attunement, containment and reflective function. I will describe the work with a patient, Jane, who was diagnosed with Myalgic Encephalomyelitis (ME) during the course of her analysis. The dynamic of her physical symptoms within the analytic work, and the impact of her internal affects and internal 'objects' within the transference and countertransference, indicated a difficulty in finding an homeostatic balance resulting in overactivity and underactivity at both somatic and psychological levels. Using the clinical work with Jane this paper will also examine the interrelationship between mother-infant attachment, an inadequate internalized maternal reflective function, affect dysregulation, unconscious fusion, the lack of psyche-soma differentiation and the impact of the latter in relation to internal regulation systems, or lack of, in patients with Chronic Fatigue Syndrome (CFS) and Myalgic Encephalomyelitis (ME). I will draw on similar work carried out by Holland (1997), Simpson (1997) and Simpson et al. (1997). The paper will also employ the concept of the reflective function (Fonagy 2001; Knox 2003), and consider Matte-Blanco's (1999) concepts of generalization and unconscious symmetry in relation to the patient's internal world. I go on to consider how analysis provides a point outside the 'fusion' that can enable the 'deadlock' to be broken. 106 PMID- 15945613 AU - Durlach J, Pages N, Bac P, Bara M, Guiet-Bara A TI - Magnesium depletion w hypo- or hyper- function of the biological clock may be involved in chronopathological forms of asthma. [FM] SO - Magnes Res. 2005 Mar;18(1):19-34. IN - SDRM, Universite Pierre et Marie Curie, 75252 Paris Cedex 05, France. jean.durlach@wanadoo.fr AB - Asthma is a chronic, inflammatory disorder of the airways leading to airflow limitation. Its worldwide rise, mainly in developed countries, is a matter of concern. Nocturnal asthma (NA) frequently occurs and concerns two thirds of asthmatics. But, it remains controversial whether NA is a distinct entity or is a manifestation of more severe asthma. Generally, it is considered as an exacerbation of the underlying pathology. The pathological mechanisms most likely involve endogenous circadian rhythms with pathological consequences on both respiratory inflammation and hyperresponsiveness. A decrease in blood and tissue magnesium levels is frequently reported in asthma and often testifies to a true magnesium depletion. The link with magnesium status and chronobiology are well established. The quality of magnesium status directly influences the Biological Clock (BC) function, represented by the suprachiasmatic nuclei and the pineal gland. Conversely, BC dysrythmias influence the magnesium status. Two types of magnesium deficits must be clearly distinguished: deficiency corresponding to an insufficient intake which can be corrected through mere nutritional Mg supplementation and depletion due to a dysregulation of the magnesium status which cannot be corrected through nutritional supplementation only, but requires the more or less specific correction of the dysregulation mechanisms. Both in clinical and in animal experiments, the dysregulation mechanisms of magnesium depletion associate a reduced magnesium intake with various types of stress including biological clock dysrhythmias. The differenciation between Mg depletion forms with hyperfunction of BC (HBC) and forms with hypofunction of BC (hBC) is seminal and the main biological marker is melatonin (MT) production alteration. We hypothesize that magnesium depletion with HBC or hBC may be involved in chronopathological forms of asthma. Nocturnal asthma would be linked to HBC, represented by an increase in MT levels. The corresponding clinical forms associate diverse expressions of nervous hypoexcitability such as depression, cluster headaches, dyssomnia, mainly advanced sleep phase syndrome, some clinical forms of chronic fatigue syndrome and of fibromyalgia. The main comorbidities are depression and/or asthenia. They take place during the night or the "bad" seasons (autumn and winter) when sunshine is at a minimum. The corresponding chronopathological therapy relies on bright light phototherapy sometimes with additional psychoanaleptics. Conversely, asthma forms linked to hBC are less frequently studied as a whole and present a decrease in MT levels. They associate various signs of nervous hyperexcitability such as anxiety, diurnal cephalalgia (mainly migraine), dyssomnia, mainly delayed sleep phase syndrome, and some clinical forms of chronic fatigue syndrome and of fibromyalgia. The treatment relies on diverse forms of "darkness therapy", possibly with the help of some psycholeptics. Finally, the treatment of asthma involves the maintenance of a standard dosing schedule of anti-asthma drugs, a balanced magnesium intake and the appropriate treatment of the chronopathological disorders. 107 PMID- 16314551 AU - Edinger JD, Wohlgemuth WK, Krystal AD, Rice JR TI - Behavioral insomnia therapy for FM pts: a randomized clinical trial.

IN - Psychology Service, Veterans Affairs Med Ctr, Durham, NC 27705, USA. jack.edinger@duke.edu AB - BACKGROUND: Insomnia is common and debilitating to fibromyalgia (FM) patients. Cognitive-behavioral therapy (CBT) is effective for many types of patients with insomnia, but has yet to be tested with FM patients. This study compared CBT with an alternate behavioral therapy and usual care for improving sleep and other FM symptoms. METHODS: This randomized clinical trial enrolled 47 FM patients with chronic insomnia complaints. The study compared CBT, sleep hygiene (SH) instructions, and usual FM care alone. Outcome measures were subjective (sleep logs) and objective (actigraphy) total sleep time, sleep efficiency, total wake time, sleep latency, wake time after sleep onset, and questionnaire measures of global insomnia symptoms, pain, mood, and quality of life. RESULTS: Forty-two patients completed baseline and continued into treatment. Sleep logs showed CBT-treated patients achieved nearly a 50% reduction in their nocturnal wake time by study completion, whereas SH therapy- and usual care-treated patients achieved only 20% and 3.5% reductions on this measure, respectively. In addition, 8 (57%) of 14 CBT recipients met strict subjective sleep improvement criteria by the end of treatment compared with 2 (17%) of 12 SH therapy recipients and 0% of the usual care group. Comparable findings were noted for similar actigraphic improvement criteria. The SH therapy patients showed favorable outcomes on measures of pain and mental well-being. This finding was most notable in an SH therapy subgroup that self-elected to implement selected CBT strategies. CONCLUSIONS: Cognitive-behavioral therapy represents a promising intervention for sleep disturbance in FM patients. Larger clinical trials of this intervention with FM patients seem warranted. 108 PMID- 16087910 AU - Edwards RR TI - Individual differences in endogenous pain modulation as a risk factor for chr pain.

IN - D o Psychiatry & Behavioral Sciences, Johns Hopkins U School o Med, Baltimore, MD 21287, USA. redwar10@jhmi.edu AB - This review summarizes evidence, primarily from recent human studies, indirectly supporting a novel hypothesis: that the assessment of healthy individuals' responses to standardized noxious stimuli in a controlled laboratory environment has important implications for the later risk of developing a broad spectrum of chronically painful conditions. Descriptions of many chronic pain syndromes note that the disorder (e.g., fibromyalgia, headache, complex regional pain syndrome) is associated with hypersensitivity to pain and with reduced endogenous inhibition of pain, implying that an individual's processing of pain-related information changes with the onset of the syndrome. However, pain sensitivity and pain-inhibitory capacity are normally distributed along a wide continuum in the general population, and recent evidence suggests that heightened baseline pain sensitivity and reduced basal pain-inhibitory processing place individuals at greater risk for experiencing severe, acute, clinical pain (e.g., postoperative pain). More controversial is the hypothesis that such individual-difference characteristics confer risk for, or protection against, chronic pain; although only a single prospective study has been published, substantial indirect evidence supports the contention that greater basal pain sensitivity and reduced pain-inhibitory capacity may act as a diathesis for chronic pain. Long-term cohort studies are necessary to test this hypothesis; such research could yield insight into the nature of chronic pain and permit greater precision in selecting high-risk individuals for chronic pain prevention research. 109 PMID- 15941694 AU - Eisen SA, Kang HK, Murphy FM, Blanchard MS, Reda DJ, Henderson WG, Toomey R, Jackson LW, Alpern R, Parks BJ, Klimas N, Hall C, Pak HS, Hunter J, Karlinsky J, Battistone MJ, Lyons MJ TI - Gulf War veterans' health: medical evaluation of a U.S. cohort.

However, the symptoms' long-term prevalence and association with deployment remain controversial. OBJECTIVE: To assess and compare the prevalence of selected medical conditions in a national cohort of deployed and nondeployed Gulf War veterans who were evaluated by direct medical and teledermatologic examinations. DESIGN: A cross-sectional prevalence study performed 10 years after the 1991 Gulf War. SETTING: Veterans were examined at 1 of 16 Veterans Affairs medical centers. PARTICIPANTS: Deployed (n = 1061) and nondeployed (n = 1128) veterans of the 1991 Gulf War. MEASUREMENTS: Primary outcome measures included fibromyalgia, the chronic fatigue syndrome, dermatologic conditions, dyspepsia, physical health-related quality of life (Short Form-36 [SF-36]), hypertension, obstructive lung disease, arthralgias, and peripheral neuropathy. RESULTS: Of 12 conditions, only 4 conditions were more prevalent among deployed than nondeployed veterans: fibromyalgia (deployed, 2.0%; nondeployed, 1.2%; odds ratio, 2.32 [95% CI, 1.02 to 5.27]); the chronic fatigue syndrome (deployed, 1.6%; nondeployed 0.1%; odds ratio, 40.6 [CI, 10.2 to 161]); dermatologic conditions (deployed, 34.6%; nondeployed, 26.8%; odds ratio, 1.38 [CI, 1.06 to 1.80]), and dyspepsia (deployed, 9.1%; nondeployed, 6.0%; odds ratio, 1.87 [CI, 1.16 to 2.99]). The mean physical component summary score of the SF-36 for deployed and nondeployed veterans was 49.3 and 50.8, respectively. LIMITATIONS: Relatively low participation rates introduce potential participation bias, and deployment-related illnesses that resolved before the research examination could not, by design, be detected. CONCLUSIONS: Ten years after the Gulf War, the physical health of deployed and nondeployed veterans is similar. However, Gulf War deployment is associated with an increased risk for fibromyalgia, the chronic fatigue syndrome, skin conditions, dyspepsia, and a clinically insignificant decrease in the SF-36 physical component score. 110 PMID- 16238661 AU - Elena Garralda M, Chalder T TI - Practitioner review: CFS in childhood. SO - J Child Psychol Psychiatry. 2005 Nov;46(11):1143-51. IN - Imperial Coll, London, UK. egarralda@imperial.ac.uk AB - BACKGROUND: Chronic fatigue syndrome (CFS) is being increasingly recognized in children and adolescents. Yet comparatively little attention has been given in the literature to management. METHODS: Description of the main features of the disorder, precipitating and maintaining factors and diagnostic assessment. Outline of different views on the nature and treatment of CFS in childhood. Description of a rehabilitation program based on cognitive behavior therapy and graded activity. RESULTS: Using adult research criteria, CFS can be diagnosed in children and adolescents. In its severe form it is often triggered by infectious illness episodes. It is commonly associated with mood disorders in the child and with mental distress and high levels of emotional involvement in parents. A number of patient support groups hold the view that CFS is a medical disorder, contest a psychiatric contribution and advocate 'pacing' as an approach to rehabilitation which includes avoiding activities. To date there is no empirical evidence for the efficacy of this approach. Research in adults, open and clinical reports in children support the use of graded activity and family cognitive behavior therapy. The main aim is to enable children, with the help of their family, to carry out their own rehabilitation with some support and guidance from a health professional. Engaging the child and family in treatment and forming a therapeutic alliance is a continual process and a crucial aspect of management, as many families view the condition as a medical disorder and are initially ambivalent towards this approach. CONCLUSIONS: There is controversy about the nature and management of CFS in childhood but a rehabilitation program based on family cognitive behavior therapy can be implemented and seems to hold most promise in the management of children with CFS. Family engagement is a crucial aspect of management. 111 PMID- 16168154 AU - Evengard B, Jacks A, Pedersen NL, Sullivan PF TI - The epidemiology of chr fatigue in the Swedish Twin Registry.

AB - BACKGROUND: Chronic fatigue syndrome (CFS) remains an idiopathic and controversial entity. METHOD: We screened 31405 individual members of the Swedish Twin Registry (aged 42-64 years) for the symptoms of fatiguing illness via a telephone questionnaire. We refined self-reported symptoms via data from several national registries and from physician review of all available medical records in order to approximate closely the dominant case definition of CFS. FINDINGS: The 6-month prevalence of CFS-like illness was 2.36% (95% CI 2.19-2.53) and was markedly higher in women than men, odds ratio 3.92 (95% CI 3.24-4.72) with no significant association with age or years of education. There was a highly significant association with occupation that disappeared after accounting for gender. INTERPRETATION: CFS-like illness may be more common that previously acknowledged. There is a marked increase in risk by gender. Previous reports that CFS is more prevalent in individuals in certain occupational categories were not confirmed and may have been due to confounding by gender. 112 PMID- 15996074 AU - Finckh A, Berner IC, Aubry-Rozier B, So AK TI - A randomized controlled trial of dehydroepiandrosterone in postmenopausal women w FM.

IN - Rheumatology D, U Hosp o Vaud (CHUV), Lausanne, Switzerland. afinckh@post.harvard.edu AB - OBJECTIVE: Patients with fibromyalgia (FM) consistently have adrenal hyporesponsiveness and low dehydroepiandrosterone (DHEA) levels. DHEA is promoted for and used by patients with FM. We tested the efficacy and safety of DHEA supplementation in ameliorating the symptoms of FM. METHODS: In a double-blind crossover study, postmenopausal women with FM were randomized to DHEA supplementation (50 mg/day) or placebo for 3 months, with a one-month washout period in between. Patients were assessed monthly for well-being and pain and by medical evaluations at the beginning and the end of each treatment period. The primary outcome was well being; secondary outcomes were pain, fatigue, cognition, sexuality, functional impairment, depression, and anxiety. RESULTS: A total of 52 patients were randomized, 47 patients completed the DHEA treatment period, and 45 the placebo treatment period. After 3 months of treatment with 50 mg of DHEA, median DHEA sulfate blood levels had tripled, but there was no improvement in well-being, pain, fatigue, cognitive dysfunction, functional impairment, depression, or anxiety, nor in objective measurements made by physicians. Androgenic side effects (greasy skin, acne, and increased growth of body hair) were more common during the DHEA treatment period (p = 0.02). CONCLUSION: DHEA does not improve quality of life, pain, fatigue, cognitive function, mood, or functional impairment in FM. 113 PMID- 16083460 AU - Fishbain DA, Lewis J, Cole B, Cutler B, Smets E, Rosomoff H, Rosomoff RS TI - Multidisciplinary pain facility Rx outcome for pain-associated fatigue.

IN - D o Psychiatry, U o Miami School o Med, Miami, FL 33136, USA. d.fishbain@miami.edu AB - OBJECTIVES: Fatigue is frequently found in chronic pain patients (CPPs) and may be etiologically related to the presence of pain. Fishbain et al. have recently demonstrated that chronic low back pain (LBP) and chronic neck pain patients are more fatigued than controls. The purpose of this study was to determine whether chronic LBP- and chronic neck pain-associated fatigue responded to multidisciplinary multimodal treatment not specifically targeted to the treatment of fatigue. DESIGN: A total of 85 chronic LBP and 33 chronic neck pain patients completed the Multidimensional Fatigue Inventory (MFI), Neuropathic Pain Scale (NPS), and Beck Depression Inventory on admission. In addition, an information tool was completed on each CPP by the senior author. This tool listed demographic information, primary and secondary pain diagnoses, Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) psychiatric diagnoses assigned, pain location, pain precipitating event, type of injury, years in pain, number of surgeries, type of surgery, type of pain pattern, opioids consumed per day in morphine equivalents, worker compensation status, and whether, according to the clinical examination, the CPP had a neuropathic pain component. At completion of the multidisciplinary multimodal treatment, each CPP again completed the MFI. Student's t-test was utilized to test for statistical changes on the MFI five scales from pre- to post-treatment. Pearson and point-biserial correlations were utilized to determine which variables significantly correlated with MFI change scores. Variables found significant at less than or equal to 0.01 were utilized in a stepwise aggression analysis to find variables predictive of change in MFI scores. SETTING: Multidisciplinary pain facility. PATIENTS: Chronic LBP and chronic neck pain patients. RESULTS: Multidisciplinary multimodal treatment significantly improved CPP fatigue as measured by the MFI. The available variables utilized to predict fatigue best explained only a small percentage (28.9%) of the variance. Improvement in fatigue was related to NPS-10 scale scores (neuropathic pain) and a previous diagnosis of fibromyalgia. CONCLUSIONS: Multidisciplinary multimodal pain facility treatment improves chronic LBP- and neck pain-associated fatigue. At the present time we cannot predict this improvement with significant accuracy. 114 PMID- 16139179 AU - Flodgren GM, Crenshaw AG, Alfredson H, Fahlstrom M, Hellstrom FB, Bronemo L, Djupsjobacka M TI - Glutamate & prostaglandin E2 in the trapezius muscle of female subjects w chr muscle pain & controls determined by microdialysis.

Box 7629, S-907 12 Umea, Sweden. gerd.flodgren@hig.se AB - Much is still unknown concerning the mechanisms underlying the development of chronic muscle pain. The presence and magnitude of inflammatory substances and neurotransmitters in chronic painful conditions is not clear. The aims of the present study were to determine, with the use of microdialysis, the interstitial concentrations and the equilibration times for PGE2 and glutamate in the trapezius muscles of nine female subjects with chronic muscle pain, and nine pain-free age-matched controls. A microdialysis probe was implanted in the upper part of the trapezius muscle and perfused with Ringer-acetate solution at a flow rate of 0.3 microL/min. Samples were obtained every 30 min, during a 4-h rest period. At equilibration, the mean concentrations (+/-SE) of PGE2 were 0.71 (+/-0.11) ng/mL for the pain-group and 0.97 (+/-0.35) ng/mL for the controls. For glutamate the mean concentrations for the pain-group were 66.3 (+/-13.3) micromol/L and 60.6 (+/-22.9) micromol/L for the controls. For the pain group and the control group, respectively, equilibration for PGE2 was reached at 180 and 150 min, and for glutamate at 150 and 120 min. The present study showed no differences between groups in the concentrations of PGE2 and glutamate in the trapezius muscle. Further, it revealed that when using the slow-flow method, a period of at least 2.0-2.5 h is needed, after probe insertion, to reach steady state for glutamate and PGE2. 115 PMID- 16091130 AU - Fowler T, Duthie P, Thapar A, Farmer A TI - The definition of disabling fatigue in children & adolescents.

IN - D o Psychological Med, Wales Coll o Medicine, Cardiff U, UK. fowlerta@cardiff.ac.uk AB - BACKGROUND: Disabling fatigue is the main illness related reason for prolonged absence from school. Although there are accepted criteria for diagnosing chronic fatigue in adults, it remains uncertain as to how best to define disabling fatigue and Chronic Fatigue Syndrome (CFS) in children and adolescents. In this population-based study, the aim was to identify children who had experienced an episode of disabling fatigue and examine the clinical and demographic differences between those individuals who fulfilled a narrow definition of disabling fatigue and those who fulfilled broader definitions of disabling fatigue. METHODS: Participants (aged 8-17 years) were identified from a population-based twin register. Parent report was used to identify children who had ever experienced a period of disabling fatigue. Standardised telephone interviews were then conducted with the parents of these affected children. Data on clinical and demographic characteristics, including age of onset, gender, days per week affected, hours per day spent resting, absence from school, comorbidity with depression and a global measure of impairment due to the fatigue, were examined. A narrow definition was defined as a minimum of 6 months disabling fatigue plus at least 4 associated symptoms, which is comparable to the operational criteria for CFS in adults. Broader definitions included those with at least 3 months of disabling fatigue and 4 or more of the associated symptoms and those with simply a minimum of 3 months of disabling fatigue. Groups were mutually exclusive. RESULTS: Questionnaires were returned by 1468 families (65% response rate) and telephone interviews were completed on 99 of the 129 participants (77%) who had experienced fatigue. There were no significant differences in demographic and clinical characteristics or levels of impairment between those who fulfilled the narrower definition and those who fulfilled the broader definitions. The only exception was the reported number of days per week that the child was affected by the fatigue. All groups demonstrated evidence of substantial impairment associated with the fatigue. CONCLUSION: Children and adolescents who do not fulfil the current narrow definition of CFS but do suffer from disabling fatigue show comparable and substantial impairment. In primary care settings, a broader definition of disabling fatigue would improve the identification of impaired children and adolescents who require support. 116 PMID- 16039337 AU - Fox RI TI - SS [Sjogren's syndrome, FM] SO - Lancet. 2005 Jul 23-29;366(9482):321-31. IN - Rheumatology Clinic, Scripps Memorial Hosp & Research Foundation, La Jolla, CA 92037, USA. bobfox@adnc.com AB - Sjogren's syndrome is a chronic autoimmune disorder of the exocrine glands with associated lymphocytic infiltrates of the affected glands. Dryness of the mouth and eyes results from involvement of the salivary and lacrimal glands. The accessibility of these glands to biopsy enables study of the molecular biology of a tissue-specific autoimmune process. The exocrinopathy can be encountered alone (primary Sjogren's syndrome) or in the presence of another autoimmune disorder such as rheumatoid arthritis, systemic lupus erythematosus, or progressive systemic sclerosis. A new international consensus for diagnosis requires objective signs and symptoms of dryness including a characteristic appearance of a biopsy sample from a minor salivary gland or autoantibody such as anti-SS-A. Exclusions to the diagnosis include infections with HIV, human T-lymphotropic virus type I, or hepatitis C virus. Therapy includes topical agents to improve moisture and decrease inflammation. Systemic therapy includes steroidal and non-steroidal anti-inflammatory agents, disease-modifying agents, and cytotoxic agents to address the extraglandular manifestations involving skin, lung, heart, kidneys, and nervous system (peripheral and central) and haematological and lymphoproliferative disorders. The most difficult challenge in diagnosis and therapy is patients with symptoms of fibromyalgia (arthralgia, myalgia, fatigue) and oral and ocular dryness in the presence of circulating antinuclear antibodies. 117 PMID- 15924878 AU - Fremont M, El Bakkouri K, Vaeyens F, Herst CV, De Meirleir K, Englebienne P TI - 2',5'-Oligoadenylate size is critical to protect RNase L against proteolytic cleavage in CFS. SO - Exp Mol Pathol. 2005 Jun;78(3):239-46. Epub 2005 Mar 2. IN - RED Laboratories, Pontbeek 61, B-1731 Zellik, Belgium. AB - A dysregulation in the 2',5'-oligoadenylate (2-5A)-dependent RNase L antiviral pathway has been detected in peripheral blood mononuclear cells (PBMC) of chronic fatigue syndrome (CFS) patients, which is characterized by upregulated 2-5A synthetase and RNase L activities, as well as by the presence of a low molecular weight (LMW) 2-5A-binding protein of 37-kDa related to RNase L. This truncated protein has been shown to originate from proteolytic cleavage of the native 83-kDa RNase L by m-calpain and human leukocyte elastase (HLE). We investigated the possible role of 2-5A oligomers in the proteolytic action toward the endonuclease and show that incubation of CFS PBMC extracts with 2-5A trimer and tetramer, but not with the dimer, results in a significant protection of the native 83-kDa RNase L against cleavage by endogenous and purified proteases. Similar results are obtained with a purified recombinant RNase L. An analysis of the size of 2-5A oligomers produced by the catalytic activity of the 2-5A synthetase present in PBMC extracts further shows that samples containing the 37-kDa RNase L preferentially produce 2-5A dimers instead of higher oligomers. Taken together, our results indicate that homodimerization of RNase L by 2-5A oligomers higher than the dimer prevents its cleavage by proteolytic enzymes. The presence of the truncated 37-kDa RNase L in PBMC extracts is therefore likely to result, not only from the abnormal activation of inflammatory proteases, but also from a dysregulation in 2-5A synthetase induction or activation towards the preferential production of 2-5A dimers. 118 PMID- 16331774 AU - Friedberg F, Leung DW, Quick J TI - Do support groups help people w CFS & FM?

METHODS: Active members (n = 32) and inactive members or dropouts (n = 135) of a regional support organization for people with CFS and FM completed a 26 item questionnaire by telephone interview or by self-completion and postal return. RESULTS: The most frequently endorsed benefits of membership were illness legitimization (67.8%), finding out helpful new information (66.4%), and feeling understood by others (62.2%). Lower frequency endorsements were given to: helped to find (35.0%) or deal with (38.5%) doctors, and helped to improve my illness (36.4%). The most frequently reported reasons for dropping out were inconvenient location (37.8%) or time (37.0%), too much negative talk or complaining (33.3%), too sick to attend (28.8%), and illness or coping improvement (29.6% each). The active-member group showed significantly higher (p < 0.04) symptom severity scores and less illness improvement (p < 0.01) in comparison to the inactive/dropout group. CONCLUSION: This cross-sectional study suggests that support groups for CFS are viewed as helpful by participants on a number of illness related issues. On the other hand, active members reported greater symptom severity and less illness improvement than inactive members or dropouts. 119 PMID- 15950390 AU - Fries E, Hesse J, Hellhammer J, Hellhammer DH TI - A new view on hypocortisolism.

AB - Low cortisol levels have been observed in patients with different stress-related disorders such as chronic fatigue syndrome, fibromyalgia, and post-traumatic stress disorder. Data suggest that these disorders are characterized by a symptom triad of enhanced stress sensitivity, pain, and fatigue. This overview will present data on the development, mechanisms and consequences of hypocortisolism on different bodily systems. We propose that the phenomenon of hypocortisolism may occur after a prolonged period of hyperactivity of the hypothalamic-pituitary-adrenal axis due to chronic stress as illustrated in an animal model. Further evidence suggests that despite symptoms such as pain, fatigue and high stress sensitivity, hypocortisolism may also have beneficial effects on the organism. This assumption will be underlined by some studies suggesting protective effects of hypocortisolism for the individual. 120 PMID- 16042909 AU - Frissora CL, Koch KL TI - Symptom overlap & comorbidity of irritable bowel syndrome w other conditions.

Symptom overlap and comorbidity between IBS and other gastrointestinal motility disorders (eg, chronic constipation, functional dyspepsia, gastroesophageal reflux disease), with gastrointestinal disorders that are not related to motility (eg, celiac disease, lactose intolerance), and with somatic conditions (eg, fibromyalgia, chronic fatigue syndrome), are frequent. The clinical associations and pathophysiologic links between IBS and these disorders continue to be explored. This review discusses overlapping symptoms and comorbidity of IBS with select gastrointestinal and non-gastrointestinal disorders and attempts to identify commonalities among these conditions. 121 PMID- 16253618 AU - Furberg H, Olarte M, Afari N, Goldberg J, Buchwald D, Sullivan PF TI - The prevalence of self-reported chr fatigue in a U.S. twin registry.

AB - OBJECTIVE: To investigate the prevalence and correlates of various definitions of self-reported lifetime fatiguing illness in a U.S. twin registry. METHODS: Data from 4591 female and male twins from the population-based Mid-Atlantic Twin Registry were available for this study. Variables representing different definitions of lifetime fatiguing illness and personal characteristics were obtained through questionnaires. Odds ratios and 95% confidence intervals were calculated as measures of association between fatigue and gender. Kaplan-Meier curves were produced to examine the age at onset for lifetime fatiguing illnesses. RESULTS: Prevalences for different definitions of self-reported lifetime fatigue ranged from 36.7% for any fatigue to 2.7% for chronic fatigue syndrome-like illness. Females were two to three times more likely to report fatigue than males. Gender differences increased as fatigue definitions grew more restrictive. Ages at onset of chronic fatiguing illness were significantly earlier and the number of ancillary symptoms was greater for females than males. People with lifetime fatigue had significantly more compromised functional status than people without lifetime fatigue. CONCLUSION: The prevalence of self-reported lifetime fatiguing illness varied widely depending upon how it was defined. Given the debilitating consequences of fatiguing illnesses, the reasons for the female predominance and the earlier onset in women should receive increased research priority. 122 PMID- 16142879 AU - Furlan R, Colombo S, Perego F, Atzeni F, Diana A, Barbic F, Porta A, Pace F, Malliani A, Sarzi-Puttini P TI - Abnormalities of cardiovascular neural control & reduced orthostatic tolerance in pts w primary FM.

Sacco, Universita degli Studi di Milano, Milano, Italy. raffaellof@fisiopat.sacco.unimi.it AB - OBJECTIVE: Fibromyalgia (FM) is a syndrome characterized by widespread musculoskeletal pain. Symptoms of orthostatic intolerance may also be present, suggesting underlying abnormalities of cardiovascular neural regulation. We tested the hypothesis that FM is characterized by sympathetic overactivity and alterations in cardiovascular autonomic response to gravitational stimulus. METHODS: Sixteen patients with primary FM and 16 healthy controls underwent electrocardiography examination, finger blood pressure, respiration, and muscle sympathetic nerve activity (MSNA) recordings at rest and during stepwise tilt test, up to 75 degrees . The autonomic profile was assessed by MSNA, plasma catecholamine, and spectral indices of cardiac sympathetic (LFRR in normalized units, NU) and vagal (HFRR both in absolute and NU) modulation and of sympathetic vasomotor control (LFSAP) computed by spectrum analysis of RR and systolic arterial pressure (SAP) variability. Arterial baroreflex function was evaluated by the SAP/RR spontaneous-sequences technique, the index a, and the gain of MSNA/diastolic pressure relationship during stepwise tilt test. RESULTS: At rest, patients showed higher values of heart rate, MSNA, LFRR NU, LF/HF, LFSAP, and reduced HFRR than controls. During tilt test, lack of increase of MSNA, less decrease of HFRR, and excessive rate (44%) of syncope were found in patients, suggesting reduced capability to enhance the sympathetic activity to vessels and withdraw the vagal modulation to sino-atrial node. Baroreflex function was similar in both groups. CONCLUSION: Patients with FM have an overall enhancement of cardiovascular sympathetic activity while recumbent. Lack of increased sympathetic discharge to vessels and decreased cardiac vagal activity characterize their autonomic profile during tilt test, and might account for the excessive rate of syncope. 123 PMID- 15471616 AU - Gaab J, Rohleder N, Heitz V, Engert V, Schad T, Schurmeyer TH, Ehlert U TI - Stress-induced changes in LPS-induced pro-inflammatory cytokine production in CFS.

IN - Center for Psychobiological & Psychosomatic Research, U o Trier, Trier, Germany. j.gaab@psychology.unizh.ch AB - OBJECTIVE: It has been suggested that a hypofunctional hypothalamic-pituitary-adrenal (HPA) axis in chronic fatigue syndrome could result in an exaggerated release of pro-inflammatory cytokines during stress. As pro-inflammatory cytokines are involved in the induction of sickness behavior and thus constitute a potential physiological correlate of stress-induced symptom exacerbation in chronic fatigue syndrome, we set out to evaluate the LPS-induced production of pro-inflammatory cytokines during psychosocial stress in CFS and healthy controls. METHOD: Twenty-one CFS patients and 20 healthy controls matched for age and gender underwent a standardized psychosocial stress test (Trier social stress test, TSST). Adrenocorticotropine hormone (ACTH), salivary cortisol and plasma cortisol levels were measured before and repeatedly following exposure to the stressor. Lipopolysaccharide-stimulated production of interleukin-6 and tumor necrosis factor-alpha were assessed at baseline as well as 10 and 60 min after the stress test. RESULTS: CFS patients showed an inverse stress-induced response pattern of LPS-stimulated cytokines responses in comparison to healthy controls, i.e. stimulated cytokine production decreased shortly after stress in CFS patients, while it increased in controls. Fatigue scores and basal LPS-induced cytokine levels were significantly associated for TNF-alpha in controls and for both cytokines in CFS patients. Stress-induced changes in stimulated cytokine production were not associated with general fatigue scores in the control group, whereas in the CFS group, fatigue scores were significantly correlated with integrated levels of LPS-induced cytokines. However, partial correlations revealed that these results were due to the high correlations with basal LPS-induced cytokine levels. CONCLUSION: CFS patients do not show an exaggerated secretion of LPS-induced cytokines. Although cortisol responses to stress were normal, pro-inflammatory cytokine levels in CFS patients were significantly attenuated. Possible intracellular mechanisms, such as for example an enhanced sensitivity to inhibitory effects of glucocorticoids, a diminished responsivity to catecholaminergic stimulation, and a disruption of intracellular activation are discussed. Basal levels of stimulated pro-inflammatory Il-6 levels are generally related to fatigue scores. However, in CFS patients this association is of greater magnitude and can also be observed for TNF-alpha. 124 PMID- 15992572 AU - Gallagher AM, Coldrick AR, Hedge B, Weir WR, White PD TI - Is the CFS an exercise phobia?

AB - OBJECTIVE: The aim of this study was to test whether patients with chronic fatigue syndrome (CFS) have an exercise phobia, by measuring anxiety-related physiological and psychological reactions to ordinary activity and exercise. METHODS: Patients and healthy but sedentary controls were assessed over 8 h of an ordinary day, and before, during and after an incremental exercise test on a motorised treadmill. To avoid confounding effects, those with a comorbid psychiatric disorder were excluded. Heart rate, galvanic skin resistance (GSR) and the amount of activity undertaken were measured, along with state and trait measures of anxiety. RESULTS: Patients with CFS were more fatigued and sleep disturbed than were the controls and noted greater effort during the exercise test. No statistically significant differences were found in either heart rate or GSR both during a normal day and before, during and after the exercise test. Patients with CFS were more symptomatically anxious at all times, but this did not increase with exercise. CONCLUSION: The data suggest that CFS patients without a comorbid psychiatric disorder do not have an exercise phobia. 125 PMID- 16012065 AU - Gard G TI - Body awareness therapy for pts w FM & chr pain.

In this article the aim and development of Basic BAT is described together with evaluations of treatments including Basic BAT.

However Basic BAT needs to be further studied in relation to patients with fibromyalgia (FM) and chronic pain. Studies so far indicate that Basic BAT has positive effects. 126 PMID- 16206355 AU - Gendreau RM, Thorn MD, Gendreau JF, Kranzler JD, Ribeiro S, Gracely RH, Williams DA, Mease PJ, McLean SA, Clauw DJ TI - Efficacy of milnacipran in pts w FM.

Current treatments are modestly effective. Arguably, the best studied and most effective compounds are tricyclic antidepressants (TCA). Milnacipran, a nontricyclic compound that inhibits the reuptake of both serotonin and norepinephrine, may provide many of the beneficial effects of TCA with a superior side effect profile. METHODS: One hundred twenty-five patients with FM were randomly assigned in a 3:3:2 ratio to receive milnacipran twice daily, milnacipran once daily, or placebo for 3 months in a double-blind dose-escalation trial; 92% of twice-daily and 81% of once-daily participants achieved dose escalation to the target milnacipran dose of 200 mg. RESULTS: The primary endpoint was reduction of pain. Both the once- and twice-daily groups showed statistically significant improvements in pain, as well as improvements in global well being, fatigue, and other domains. Response rates for patients receiving milnacipran were equal in patients with and without comorbid depression, but placebo response rates were considerably higher in depressed patients, leading to significantly greater overall efficacy in the nondepressed group. CONCLUSION: In this Phase II study, milnacipran led to statistically significant improvements in pain and other symptoms of FM. The effect sizes were equal to those previously found with TCA, and the drug was generally well tolerated. 127 PMID- 16259310 AU - Gerwin RD TI - A review of myofascial pain & FM--factors that promote their persistence. SO - Acupunct Med. 2005 Sep;23(3):121-34. IN - gerwin@painpoints.com AB - Chronic muscle pain (myalgia) is a common problem throughout the world. Seemingly simple, it is actually a difficult problem for the clinician interested in determining the aetiology of the pain, as well as in managing the pain. The two common muscle pain conditions are fibromyalgia and myofascial pain syndrome. Fibromyalgia is a chronic, widespread muscle tenderness syndrome, associated with central sensitisation. It is often accompanied by chronic sleep disturbance and fatigue, visceral pain syndromes like irritable bowel syndrome and interstitial cystitis. Myofascial pain syndrome is an overuse or muscle stress syndrome characterised by the presence of trigger points in muscle. The problem these syndromes pose lies not in making the diagnosis of muscle pain. Rather, it is the need to identify the underlying cause(s) of persistent or chronic muscle pain in order to develop a specific treatment plan. Chronic myalgia may not improve until the underlying precipitating or perpetuating factor(s) are themselves managed. Precipitating or perpetuating causes of chronic myalgia include structural or mechanical causes like scoliosis, localised joint hypomobility, or generalised or local joint laxity; and metabolic factors like depleted tissue iron stores, hypothyroidism or Vitamin D deficiency. Sometimes, correction of an underlying cause of myalgia is all that is needed to resolve the condition. 128 PMID- 15880832 AU - Giesecke T, Gracely RH, Williams DA, Geisser ME, Petzke FW, Clauw DJ TI - The relationship between depression, clinical pain, & experimental pain in a chr pain cohort. [FM] SO - Arthritis Rheum. 2005 May;52(5):1577-84. IN - U o Michigan, Ann Arbor, USA. AB - OBJECTIVE: Individuals with chronic pain frequently display comorbid depression, but the impact of symptoms of depression on pain processing is not completely understood. This study evaluated the effect of symptoms of depression and/or clinically diagnosed major depressive disorder (MDD) on pain processing in patients with fibromyalgia (FM). METHODS: Results of quantitative sensory testing and neural responses to equally painful pressure stimuli (measured by functional magnetic resonance imaging [fMRI]) were compared with the levels of symptoms of depression and comorbid MDD among patients with FM. RESULTS: Neither the level of symptoms of depression nor the presence of comorbid MDD was associated with the results of sensory testing or the magnitude of neuronal activation in brain areas associated with the sensory dimension of pain (primary and secondary somatosensory cortices). However, symptoms of depression and the presence of MDD were associated with the magnitude of pain-evoked neuronal activations in brain regions associated with affective pain processing (the amygdalae and contralateral anterior insula). Clinical pain intensity was associated with measures of both the sensory dimension of pain (results of sensory testing) and the affective dimension of pain (activations in the insula bilaterally, contralateral anterior cingulate cortex, and prefrontal cortex). CONCLUSION: In patients with FM, neither the extent of depression nor the presence of comorbid major depression modulates the sensory-discriminative aspects of pain processing (i.e., localizing pain and reporting its level of intensity), as measured by sensory testing or fMRI. However, depression is associated with the magnitude of neuronal activation in brain regions that process the affective-motivational dimension of pain. These data suggest that there are parallel, somewhat independent neural pain-processing networks for sensory and affective pain elements. The implication for treatment is that addressing an individual's depression (e.g., by prescribing an antidepressant medication that has no analgesic properties) will not necessarily have an impact on the sensory dimension of pain. 129 PMID- 15664781 AU - Glaser R, Padgett DA, Litsky ML, Baiocchi RA, Yang EV, Chen M, Yeh PE, Klimas NG, Marshall GD, Whiteside T, Herberman R, Kiecolt-Glaser J, Williams MV TI - Stress-associated changes in the steady-state expression of latent Epstein-Barr virus: implications for CFS & cancer.

The reason for these antibody patterns and the role these proteins might play in the pathophysiology of disease, separate from their role in virus replication, is unknown. In this series of studies, we found that purified EBV deoxyuridine triphosphate nucleotidohydrolase (dUTPase) can inhibit the replication of human peripheral blood mononuclear cells in vitro and upregulate the production of TNF-alpha, IL-1beta, IL-6, IL-8, and IL-10. It also enhanced the ability of natural killer cells to lyse target cells. The EBV dUTPase also significantly inhibited the replication of mitogen-stimulated lymphocytes and the synthesis of IFN-gamma by cells isolated from lymph nodes and spleens obtained from mice inoculated with the protein. It also produced sickness behaviors known to be induced by some of the cytokines that were studied in the in vitro experiments. These symptoms include an increase in body temperature, a decrease in body mass and in physical activity. The data provide a new perspective on how an early nonstructural EBV-encoded protein can cause immune dysregulation and produce clinical symptoms observed in patients with chronic fatigue syndrome (CFS) separate from its role in virus replication and may serve as a new approach to help identify one of the etiological agents for CFS. The data also provide additional insight into the pathophysiology of EBV infection, inflammation, and cancer. 130 PMID- 15865951 AU - Glass JM, Park DC, Minear M, Crofford LJ TI - Memory beliefs & function in FM pts.

METHODS: Twenty-three FM patients, 23 age- and education-matched controls, and 22 older controls completed the Metamemory in Adulthood (MIA) questionnaire, which assessed beliefs about seven aspects of memory function. Group differences on the seven scales were assessed, and scores on the capacity scale were correlated with objective memory performance. RESULTS: FM patients reported lower memory capacity and more memory deterioration than did either control group. Patients reported lower control or self-efficacy over memory, higher achievement motivation, higher strategy use, and higher anxiety about memory than age-matched controls did. Among the patients, perceived capacity, achievement motivation, and self-efficacy were significantly correlated with objective memory performance on a recall task. CONCLUSION: FM patients' complaints about memory function have some accuracy. 131 PMID- 15599128 AU - Goossens ME, Vlaeyen JW, Hidding A, Kole-Snijders A, Evers SM TI - Treatment expectancy affects the outcome of cognitive-behavioral interventions in chr pain.

IN - D o Med, Clinical, & Experimental Psychology, Maastricht U, Maastricht, The Netherlands. m.goossens@dep.unimaas.nl AB - Patients' initial beliefs about the success of a given pain treatment are shown to have an important influence on the final treatment outcome. The aims of the paper are to assess determinants of patients' treatment expectancy and to examine the extent to which treatment expectancy predicts the short-term and long-term outcome of cognitive-behavioral treatment of chronic pain. This study employs the data of 2 pooled randomized clinical trials evaluating the effectiveness of cognitive-behavioral interventions for 171 patients with fibromyalgia and chronic low back pain. Pretreatment and posttreatment expectancy were measured by a short questionnaire, which was based on the procedure by Borkovec and Nau. Four composite outcome variables (pain coping and control, motoric behavior, negative affect, and quality of life) were measured before and after the intervention and at 12 months follow-up. Furthermore, several patient characteristics were taken into account. Patients with higher treatment expectancies significantly received less disability compensation and were less fearful. A regression model of 3 factors (better pain coping and control, active and positive interpretation of pain, and less disability compensation) significantly explained 10% of the variance in pretreatment expectancy. Pretreatment expectancy significantly predicted each of the 4 outcome measures immediately after treatment and at 12 months follow-up. This study corroborates the importance of treatment expectation before entering a cognitive-behavioral intervention in patients with chronic musculoskeletal pain. 132 PMID- 15710856 AU - Gottschalk M, Kumpfel T, Flachenecker P, Uhr M, Trenkwalder C, Holsboer F, Weber F TI - Fatigue & regulation of the hypothalamo-pituitary-adrenal axis in multiple sclerosis. [CF] SO - Arch Neurol. 2005 Feb;62(2):277-80. IN - Max Planck Inst o Psychiatry, Munich, Germany. AB - BACKGROUND: Fatigue is a common and disabling symptom in patients with multiple sclerosis (MS). Underlying mechanisms postulated so far have involved localization of brain lesions and abnormalities of the neuroendocrine system and cytokine regulation. OBJECTIVE: To investigate the relationship between fatigue and the hypothalamo-pituitary-adrenal (HPA) axis in patients with MS. DESIGN: A prospective survey. SETTING: Outpatient and inpatient study at the Max Planck Institute of Psychiatry, Munich, Germany. PATIENTS: Thirty-one patients with clinically definite MS, a relapsing-remitting disease course, and without MS-specific treatment. INTERVENTIONS: Assessment of fatigue with 3 questionnaires: the Fatigue Severity Scale (FSS), the Modified Fatigue Impact Scale (MFIS), and the Visual Analog Scale. Assessment of HPA axis regulation with the combined dexamethasone-corticotropin releasing hormone (Dex-CRH) test. RESULTS: The FSS score was significantly correlated with the MFIS score. Patients with fatigue had significantly elevated adrenocorticotropin (ACTH) levels in the combined Dex-CRH test. CONCLUSIONS: In contrast to results for chronic fatigue syndrome, where a hyporeactivity of the HPA axis has been shown, MS patients with fatigue exhibited a higher activity of the HPA axis than those without fatigue, as evidenced by significantly increased ACTH concentrations. Proinflammatory cytokines, known to be elevated in patients with MS, may cause both HPA axis alterations and fatigue. 133 PMID- 16474286 AU - Guven AZ, Kul Panza E, Gunduz OH TI - Depression & psychosocial factors in Turkish women w FM syndrome.

METHODS: Fifty-three women with FS and 54 healthy women were included in the study. The visual analogue scale (VAS) was applied to evaluate the degree of pain and Beck depression inventory (BDI) for depression. RESULTS: Mean age of the FS and the healthy women groups was 42.6+/-9.6 (21-63) and 39.4+/-13.2 (24-60) years respectively; which were statistically similar (P>0.05). Of the patients, 69.8% were married, and the mean years of education was 8.7+/-4.8 years. Marriage among relatives was found in 18.4% of the patients. The mean VAS score of the patients was 7.2+/-1.7 cm with the mean duration of pain 5+/-4.6 years. Mean BDI scores of FS patients and the healthy group were 15.7+/-8.7 and 10.2+/-5.5 respectively; the difference between the 2 groups was statistically significant (P<0.05). According to the BDI scores, 90% of FS patients were classified as depressed; among them, 50% had minor, 38% moderate, and 2% severe depression. FS patients who were married to a relative had higher scores of BDI (r=0.414, P=0.013). There was negative correlation between BDI score and patients' total year of education (r=-0.295, P=0.037); and the husband's education level (r=-0.367, P=0.030). According to BDI, the c2 test revealed significant depression in patients with sleep-disorders (P=0.009). CONCLUSIONS: We found a significant degree of depression in Turkish female FS patients. This situation is found to be correlated with the education level of both patient and husband; marital status, and sleep-disorder; it is suggested that these factors should be taken into consideration in the diagnosis, treatment and follow-up of FS patients. 134 PMID- 15781924 AU - Haines LC, Saidi G, Cooke RW TI - Prevalence of severe fatigue in primary care.

IN - The Grange, Bristol BS8 1AU, UK. w.hamilton@bristol.ac.uk AB - BACKGROUND: Several different diagnostic labels exist for the fatigue syndromes, including chronic fatigue syndrome (CFS), myalgic encephalomyelitis (ME) and postviral fatigue syndrome (PVFS). An allied condition is fibromyalgia. No study has examined prognostic differences across these different labels. OBJECTIVE: To compare the prognoses of patients labelled with different fatigue syndromes in primary care. METHODS: We performed a longitudinal survey, using electronic records from the General Practice Research Database. All 18,122 patients diagnosed by their GP with a fatigue syndrome from 1988-2001 with a minimum of one year of records after diagnosis were collated into four groups: CFS, ME, PVFS and fibromyalgia. CFS and ME were combined for the main analysis as no code for CFS was available until 1995. The length of illness was calculated as the interval between the diagnosis and the last recorded fatigue symptom, expressed as days per year, to account for differing lengths of record after diagnosis. RESULTS: Patients with CFS/ME combined had a worse prognosis (median length of illness 80 days per year; interquartile range 0-242) than fibromyalgia (51; 0-244) or PVFS 0 (0-108), a significant difference, P < 0.001. In a subgroup analysis, ME had a worse prognosis (median length of illness in days per year 106; interquartile range 0-259) than CFS (33; 0-170), P < 0.001, in spite of a better course before diagnosis. Secondary outcome measures were consistent with these results. CONCLUSION: There were important differences in outcome between the various fatigue labels, with ME having the worst prognosis and PVFS the best. This could be an adverse effect of the label ME itself. Alternatively, patients who are destined to have a worse prognosis may preferentially attract the ME label. Our data support the first interpretation. 136 PMID- 15693098 AU - Haq SA, Darmawan J, Islam MN, Uddin MZ, Das BB, Rahman F, Chowdhury MA, Alam MN, Mahmud TA, Chowdhury MR, Tahir M TI - Prevalence of rheumatic diseases & associated outcomes in rural & urban communities in Bangladesh: a COPCORD study.

IN - Rheumatology Wing, D o Med, Bangabandhu Sheikh Mujib Med U Shahbagh, Dhaka, Indonesia. sahaq@citech.net AB - OBJECTIVE: To estimate the burden of rheumatic disorders in adults (age >/= 15 yrs) in Bangladeshi rural and urban communities. METHODS: The survey was carried out in a rural community, an urban slum, and an affluent urban community with samples of 2635, 1317, and 1259 adults, respectively. Through door-to-door surveys, trained interviewers identified subjects with musculoskeletal pain. A socio-culturally adapted and validated Bengali version of the COPCORD (Community Oriented Program for Control of Rheumatic Disorders) questionnaire was used. Trained internists and rheumatologists examined the positive respondents using an English COPCORD examination sheet to identify respondents with definite rheumatic disorders and to reach a diagnosis. RESULTS: The overall point prevalence of musculoskeleletal pain was 26.3%. The point prevalence estimates of musculoskeletal pain in rural, urban slum, and affluent urban communities were 26.2% (women 31.3%, men 21.1%), 24.9% (women 27.5%, men 22.6%), and 27.9% (women 35.5%, men 18.6%), respectively. Most commonly affected sites were low back, knees, hips, and shoulders in all 3 communities. The point prevalence of definite rheumatic disorders was 24.0%. The commonest rheumatic disorders were osteoarthritis of the knees, nonspecific low back pain, lumbar spondylosis, fibromyalgia, and soft tissue rheumatism. Their prevalence estimates were 7.5%, 6.6%, 5.0%, 4.4%, and 2.7%, respectively, in the rural, 9.2%, 9.9%, 2.0%, 3.2%, and 2.5%, respectively, in the urban slum, and 10.6%, 9.2%, 2.3%, 3.3%, and 3.3% in the urban affluent community. The point prevalence of functional disability was 25.5%, 23.3%, and 24.8%, respectively, in the rural, urban slum, and urban affluent communities. Among the positive respondents, 22%, 52%, and 22% reported loss of work for durations of 49.3 +/- 47.5, 50.90 +/- 103.3, and 29.25 +/- 56.5 days, respectively, within the previous year. CONCLUSION: Rheumatic disorders are common causes of morbidity, disability, and work loss in rural and urban communities of Bangladesh. Women are affected more frequently than men. Mechanical disorders are more common than inflammatory arthropathies. 137 PMID- 16258905 AU - Harris RE, Williams DA, McLean SA, Sen A, Hufford M, Gendreau RM, Gracely RH, Clauw DJ TI - Characterization & consequences of pain variability in individuals w FM.

IN - Chronic Pain & Fatigue Research Ctr, U o Michigan Med Center, 24 Frank Lloyd Wright Drive, PO Box 385, Ann Arbor, MI 48106, USA. reharris@med.umich.edu AB - OBJECTIVE: A growing body of evidence suggests that real-time electronic assessments of pain are preferable to traditional paper-and-pencil measures. We used electronic assessment data derived from a study of patients with fibromyalgia (FM) to examine variability of pain over time and to investigate the implications of pain fluctuation in the context of a clinical trial. METHODS: The study group comprised 125 patients with FM who were enrolled in a randomized, placebo-controlled trial of milnacipran. Pain intensity levels were captured in real time by participants using electronic diaries. Variability in pain was assessed as the standard deviation of pain entries over time (pain variability index [PVI]). RESULTS: Substantial between-subject differences in pain variability were observed (mean +/- SD PVI 1.61 +/- 0.656 [range 0.27-4.05]). The fluctuation in pain report was constant over time within individuals (r = 0.664, P < 0.001). Individuals with greater variability were more likely to be classified as responders in a drug trial (odds ratio 6.14, P = 0.006); however, this association was primarily attributable to a greater change in pain scores in individuals receiving placebo (r = 0.460, P = 0.02) rather than active drug (r = 0.09, P > 0.10). CONCLUSION: Among individuals with FM, there were large between-subject differences in real-time pain reports. Pain variability was relatively constant over time within individuals. Perhaps the most important finding is that individuals with larger pain fluctuations were more likely to respond to placebo. It is not clear whether these findings are applicable only to patients with FM or whether they may also be seen in patients with other chronic pain conditions. 138 PMID- 16131290 AU - Harris RE, Tian X, Williams DA, Tian TX, Cupps TR, Petzke F, Groner KH, Biswas P, Gracely RH, Clauw DJ TI - Treatment of FM w formula acupuncture: investigation of needle placement, needle stimulation, & Rx frequency.

DESIGN/SETTINGS/SUBJECTS: A single-site, single-blind, randomized trial of 114 participants diagnosed with fibromyalgia for at least 1 year was performed. INTERVENTION: Participants were randomized to one of four treatment groups: (1) T/S needles placed in traditional sites with manual needle stimulation (n = 29): (2) T/0 traditional needle location without stimulation (n = 30); (3) N/S needles inserted in nontraditional locations that were not thought to be acupuncture sites, with stimulation (n = 28); and (4) N/0 nontraditional needle location without stimulation (n = 2 7). All groups received treatment once weekly, followed by twice weekly, and finally three times weekly, for a total of 18 treatments. Each increase in frequency was separated by a 2-week washout period. OUTCOME MEASURES: Pain was assessed by a numerical rating scale, fatigue by the Multi-dimensional Fatigue Inventory, and physical function by the Short Form-36. RESULTS: Overall pain improvement was noted with 25%-35% of subjects having a clinically significant decrease in pain; however this was not dependent upon "correct" needle stimulation (t = 1.03; p = 0.307) or location (t = 0.76; p = 0.450). An overall dose effect of treatment was observed, with three sessions weekly providing more analgesia than sessions once weekly (t = 2.10; p = 0.039). Among treatment responders, improvements in pain, fatigue, and physical function were highly codependent (all p < or = 0.002). CONCLUSIONS: Although needle insertion led to analgesia and improvement in other somatic symptoms, correct needle location and stimulation were not crucial. 139 PMID- 16198192 AU - Henderson M, Tannock C TI - Use of depression rating scales in CFS.

AB - OBJECTIVE: The aim of this study was to examine the performance of three commonly used depression rating scales in a hospital sample of patients with chronic fatigue syndrome (CFS). METHODS: Sixty-one patients with CDC criteria for CFS completed the General Health Questionnaire (GHQ), the Hamilton Depression Scale (HAM-D) and the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D). Current psychiatric status was assessed using the Structured Clinical Interview for DSM-III-R. DISORDERS: Patient version (SCID-P). Receiver operating curves were drawn for each of the depression rating scales. RESULTS: Thirty-one percent of the patients were depressed according to the SCID-P. Using the standard cut-offs, both GHQ and HAM-D overestimated the number of depressed patients, whilst the HADS-D underestimated the number. The receiver operating curves suggest that the optimum cut-offs for GHQ, HAM-D and HADS-D in this population are 7/8, 13/14 and 8/9, respectively. CONCLUSIONS: Standard cutoffs may not be appropriate when using depression rating scales in CFS patients in a tertiary care setting. 140 PMID- 16012061 AU - Henriksson CM, Liedberg GM, Gerdle B TI - Women w FM: work & rehabilitation. SO - Disabil Rehabil. 2005 Jun 17;27(12):685-94. IN - Section o Occupational Therapy, Linkoping U, Linkoping, Sweden. AB - PURPOSE: To explore disability in women with fibromyalgia with a focus on their work situation. METHOD: Review of literature on work status of women with fibromyalgia. RESULTS: Major differences exist between studies in reported disability and in the percentages of women working. Limitations caused by pain, fatigue, decreased muscle strength, and endurance influence work capacity. However, 34 - 77% of the women work. Individual adjustments in the work situation are reported. When the women find a level that matches their ability, they continue to work and find satisfaction in their work role. Many factors besides degree of impairment or disability influence whether clients with longstanding pain can remain in their work role or return to work after sickness leave. CONCLUSION: The total life situation, other commitments, type of work tasks, the ability to influence the work situation, and the physical and psychosocial work environment are important factors in determining whether a person can remain in a work role. More knowledge is needed about how to adjust work conditions for people with partial work ability to the benefit of society and the individual. 141 PMID- 15861265 AU - Hershfield NB TI - Nongastrointestinal Sx of irritable bowel syndrome: an office-based clinical survey.

IN - Division o Gastroenterology, D o Med, U o Calgary, Calgary, Alberta. gutdoc1@shaw.ca AB - Irritable bowel syndrome (IBS) is the most prevalent gastrointestinal problem faced by practicing gastroenterologists. For many years, nongastrointestinal symptoms have been documented in IBS patients, but the medical literature does not emphasize them. The present study explored how IBS and inflammatory bowel disease patients differ in their reporting of nongastrointestinal symptoms. Information from 200 consecutive patients with IBS and a similar number of patients with Crohn's disease (in a single gastroenterology practice) was obtained at the initial visit using a simple questionnaire. Comparison of the data revealed that IBS patients describe certain nongastrointestinal symptoms far more frequently than do those with inflammatory bowel disease. It is recommended that these symptoms be considered along with the generally accepted criteria for making a positive diagnosis of IBS. 142 PMID- 16171242 AU - Hindmarch I, Dawson J, Stanley N TI - A double-blind study in healthy volunteers to assess the effects on sleep of pregabalin compared w alprazolam & placebo.

AB - STUDY OBJECTIVES: To assess the effects of pregabalin compared with alprazolam and placebo on aspects of sleep in healthy volunteers. DESIGN: Randomized, double-blind, placebo- and active-controlled, 3-way crossover. SETTING: Single research center. PARTICIPANTS AND INTERVENTIONS: Healthy adult (12 men) volunteers (N=24) received oral pregabalin 150 mg t.i.d., alprazolam 1 mg t.i.d., and placebo t.i.d. for 3 days. MEASUREMENTS AND RESULTS: Objective sleep was measured by an 8-channel polysomnograph; subjective sleep was measured using the Leeds Sleep Evaluation Questionnaire. Compared with placebo, pregabalin significantly increased slow-wave sleep both as a proportion of the total sleep period and the duration of stage 4 sleep. Alprazolam significantly reduced slow-wave sleep. Pregabalin and alprazolam produced modest, but significant, reductions in sleep-onset latency compared with placebo. Rapid eye movement sleep latency after pregabalin was no different than placebo but was significantly shorter than that found with alprazolam. Although there were no differences between the active treatments, both pregabalin and alprazolam reduced rapid eye movement sleep as a proportion of the total sleep period compared with placebo. Pregabalin also significantly reduced the number of awakenings of more than 1 minute in duration. Leeds Sleep Evaluation Questionnaire ratings of the ease of getting to sleep and the perceived quality of sleep were significantly improved following both active treatments, and ratings of behavior following awakening were significantly impaired by both drug treatments. CONCLUSIONS: Pregabalin appears to have an effect on sleep and sleep architecture that distinguishes it from benzodiazepines. Enhancement of slow-wave sleep is intriguing, since reductions in slow-wave sleep have frequently been reported in fibromyalgia and general anxiety disorder. 143 PMID- 16170166 AU - Hjermstad MJ, Fossa SD, Oldervoll L, Holte H, Jacobsen AB, Loge JH TI - Fatigue in long-term Hodgkin's Disease survivors: a follow-up study.

IN - D o Oncology, Ulleval U Hosp HF, KSLB, 0407 Oslo, Norway. m.j.hjermstad@basalmed.uio.no AB - PURPOSE: To describe total fatigue (TF) and chronic fatigue (CF) in 476 long-term Hodgkin's disease survivors (HDSs). The development in CF over time was explored in 280 of the patients who had also been assessed 8 years earlier. PATIENTS AND METHODS: In 2003, the Fatigue Questionnaire was mailed to 610 successfully treated HDSs at the Norwegian Radium Hospital from 1971 to 1997. Mean TF scores and occurrence of CF were compared with general population (GP) values. RESULTS: Four hundred seventy-six complete forms (81%) were received (median age, 46 years; 56% males, median follow-up time, 195 months). There was a positive association between age and TF (P < .05), whereas presence of B symptoms at diagnosis and treatment before 1980 were associated with CF. Mean TF scores were elevated in HDSs compared with the GP (mean TF score, 14.6; 95% CI, 14.1 to 15.7 v 12.1; 95% CI, 11.9 to 12.3, respectively; P < .001), as was the proportion of persons with CF (30% v 11%, respectively; odds ratio = 3.6; P < .001). The 70 patients with CF 8 years earlier still reported higher TF at follow-up than the 210 patients without CF at the previous assessment (mean TF score, 17.0; 95% CI, 15.6 to 18.3 v 13.1; 95% CI, 12.9 to 14.1, respectively; P < .001). Significantly more patients with persisting CF had B symptoms at diagnosis compared with patients who had recovered (P = .05). No significant association with treatment modality and intensity was found. CONCLUSION: Fatigue remains a major complaint in HDSs several years after treatment, but the association between treatment and fatigue still remains unclear. Many HDSs may recover from CF, particularly patients without B symptoms at diagnosis. 144 PMID- 16052595 AU - Holman AJ, Myers RR TI - A randomized, double-blind, placebo-controlled trial of pramipexole, a dopamine agonist, in pts w FM receiving concomitant medications. SO - Arthritis Rheum. 2005 Aug;52(8):2495-505. IN - Pacific Rheumatology Associates, Renton, Washington 98055, USA. ajhseattle@aol.com AB - OBJECTIVE: To assess the efficacy and safety of pramipexole, a dopamine 3 receptor agonist, in patients with fibromyalgia. METHODS: In this 14-week, single-center, double-blind, placebo-controlled, parallel-group, escalating-dose trial, 60 patients with fibromyalgia were randomized 2:1 (pramipexole:placebo) to receive 4.5 mg of pramipexole or placebo orally every evening. The primary outcome was improvement in the pain score (10-cm visual analog scale [VAS]) at 14 weeks. Secondary outcome measures were the Fibromyalgia Impact Questionnaire (FIQ), the Multidimensional Health Assessment Questionnaire (MDHAQ), the pain improvement scale, the tender point score, the 17-question Hamilton Depression Inventory (HAM-d), and the Beck Anxiety Index (BAI). Patients with comorbidities and disability were not excluded. Stable dosages of concomitant medications, including analgesics, were allowed. RESULTS: Compared with the placebo group, patients receiving pramipexole experienced gradual and more significant improvement in measures of pain, fatigue, function, and global status. At 14 weeks, the VAS pain score decreased 36% in the pramipexole arm and 9% in the placebo arm (treatment difference -1.77 cm). Forty-two percent of patients receiving pramipexole and 14% of those receiving placebo achieved > or =50% decrease in pain. Secondary outcomes favoring pramipexole over placebo included the total FIQ score (treatment difference -9.57) and the percentages of improvement in function (22% versus 0%), fatigue (29% versus 7%), and global (38% versus 3%) scores on the MDHAQ. Compared with baseline, some outcomes showed a better trend for pramipexole treatment than for placebo, but failed to reach statistical significance, including improvement in the tender point score (51% versus 36%) and decreases in the MDHAQ psychiatric score (37% versus 28%), the BAI score (39% versus 27%), and the HAM-d score (29% versus 9%). No end points showed a better trend for the placebo arm. The most common adverse events associated with pramipexole were transient anxiety and weight loss. No patient withdrew from the study because of inefficacy or an adverse event related to pramipexole. CONCLUSION: In a subset of patients with fibromyalgia, approximately 50% of whom required narcotic analgesia and/or were disabled, treatment with pramipexole improved scores on assessments of pain, fatigue, function, and global status, and was safe and well-tolerated. 145 PMID- 16076786 AU - Hutchings A, Raine R, Sanderson C, Black N TI - An experimental study of determinants of the extent of disagreement within clinical guideline development groups.

IN - Health Services Research Unit, London School o Hygiene & Tropical Med, London WC1E 7HT, UK. andrew.hutchings@lshtm.ac.uk AB - OBJECTIVE: To assess the effect of design features and clinical and social cues on the extent of disagreement among participants in a formal consensus development process. METHODS: Factorial design involving 16 groups consisting of 135 general practitioners (GPs) and 42 mental health professionals from England. The groups rated the appropriateness of four mental health interventions for three conditions (chronic back pain, irritable bowel syndrome, and chronic fatigue syndrome) in the context of various clinical and social cues. The groups differed in three design features: provision of a systematic literature review (versus not provided), group composition (mixed versus GP only), and assumptions about the healthcare resources available (realistic versus idealistic). Disagreement was measured using the mean absolute deviation from a group's median rating for a scenario. RESULTS: None of the design features significantly affected the extent of disagreement within groups (all p>0.3). Disagreement did differ between treatments (closer consensus for cognitive behavioural therapy and behavioural therapy than for brief psychodynamic intervention therapy and antidepressants) and cues (closer consensus for depressed patients and patients willing to try any treatment). CONCLUSION: In terms of the extent of disagreement in the groups in this study, formal consensus development was a robust technique in that the results were not dependent on the way it was conducted. 146 PMID- 15730417 AU - Inder WJ, Prickett TC, Mulder RT TI - Normal opioid tone & hypothalamic-pituitary-adrenal axis function in CFS despite marked functional impairment.

DESIGN: Single-blinded case-control study measuring functional and psychological status, basal hormonal parameters and ACTH/cortisol response to naloxone and ovine corticotrophin-releasing hormone (oCRH) vs. placebo in people with CFS and healthy controls. PATIENTS: Twelve people with CFS and 11 age-matched controls. MEASUREMENTS: Hormonal parameters: basal levels of 09:00 h plasma cortisol, dehydroepiandrosterone sulfate (DHEAS) and IGF-1. 24-h urinary free cortisol. Plasma ACTH and cortisol response to naloxone 125 microg/kg, oCRH 1 microg/kg and placebo (normal saline). Psychological parameters: SF-36, Hamilton Depression Score, Hospital Anxiety and Depression Scale and Fatigue Scale. RESULTS: There were highly significant differences between the CFS subjects and the controls with respect to the measures of fatigue and physical functioning. However, there were no differences in basal levels of 09:00 h cortisol (367 +/- 37 vs. 331 +/- 39 nmol/l, P = 0.51), DHEAS (4.2 +/- 0.6 vs. 4.0 +/- 0.5 micromol/l, P = 0.81), 24-h urinary free cortisol (182 +/- 27 vs. 178 +/- 21 nmol/24 h, P = 0.91) or IGF-1 (145 +/- 19 vs. 130 +/- 11 microg/l, P = 0.52) between the CFS group and controls, respectively. There was also no difference between the groups with respect to the ACTH and cortisol response to either oCRH or naloxone. CONCLUSIONS: Our data do not support an aetiological role for deficiency in central opioids or the HPA axis in the symptoms of CFS. 147 PMID- 16415546 AU - Iwakami E, Arashima Y, Kato K, Komiya T, Matsukawa Y, Ikeda T, Arakawa Y, Oshida S TI - Treatment of CFS w antibiotics: pilot study assessing the involvement of Coxiella burnetii infection. SO - Intern Med. 2005 Dec;44(12):1258-63. IN - D o Legal Med, Nihon U School o Medicine, Tokyo, Japan. AB - OBJECTIVE: To examine whether Coxiella burnetii (C. burnetii) is involved in chronic fatigue syndrome (CFS), we administered tetracycline antibiotics to subjects with CFS, and followed changes in clinical symptoms, PCR findings, and C. burnetii antibody titers. PATIENTS AND METHODS: The subjects were 8 patients with CFS and 213 with nonspecific complaints such as chronic fatigue and low-grade fever for several months or longer but not meeting the diagnostic criteria for CFS. All were examined for C. burnetii infection by nested PCR and the indirect immunofluorescence test (IF). RESULTS: Four CFS patients (the CFS group) and 54 controls [the post-Q fever fatigue syndrome (QFS) group] positive for C. burnetii were treated mainly with minocycline or doxycycline (100 mg/day) for 3 months. After treatment, all 58 patients tested negative for C. burnetii infection. In the CFS group, no significant difference was noted between the mean pre- and post-treatment temperatures or headache scores. Similarly, there was no significant improvement in performance status (PS) scores. In the QFS group, however, mean temperatures and headache scores were significantly decreased after treatment (p<0.001). PS scores were also improved. CONCLUSION: These results suggest the possibility of direct involvement of C. burnetii in the pathological state of CFS to be low, despite the C. burnetii infection rate being high in CFS patients. This is a pilot study and further larger investigations are necessary to confirm our preliminary results. 148 PMID- 15715687 AU - Jammes Y, Steinberg JG, Mambrini O, Bregeon F, Delliaux S TI - CFS: assessment of increased oxidative stress & altered muscle excitability in response to incremental exercise.

IN - Laboratoire de Physiopathologie Respiratoire (UPRES EA 2201), Faculte de Medecine, Institut Federatif de Recherche Jean Roche, Marseille, France. jammes.y@jean-roche.univ-mrs.fr AB - OBJECTIVES: Because the muscle response to incremental exercise is not well documented in patients suffering from chronic fatigue syndrome (CFS), we combined electrophysiological (compound-evoked muscle action potential, M wave), and biochemical (lactic acid production, oxidative stress) measurements to assess any muscle dysfunction in response to a routine cycling exercise. DESIGN: This case-control study compared 15 CFS patients to a gender-, age- and weight-matched control group (n=11) of healthy subjects. INTERVENTIONS: All subjects performed an incremental cycling exercise continued until exhaustion. MAIN OUTCOME MEASURES: We measured the oxygen uptake (VO2), heart rate (HR), systemic blood pressure, percutaneous O2 saturation (SpO2), M-wave recording from vastus lateralis, and venous blood sampling allowing measurements of pH (pHv), PO2 (PvO2), lactic acid (LA), and three markers of the oxidative stress (thiobarbituric acid-reactive substances, TBARS, reduced glutathione, GSH, and ascorbic acid, RAA). RESULTS: Compared with control, in CFS patients (i) the slope of VO2 versus work load relationship did not differ from control subjects and there was a tendency for an accentuated PvO2 fall at the same exercise intensity, indicating an increased oxygen uptake by the exercising muscles; (ii) the HR and blood pressure responses to exercise did not vary; (iii) the anaerobic pathways were not accentuated; (iv) the exercise-induced oxidative stress was enhanced with early changes in TBARS and RAA and enhanced maximal RAA consumption; and (v) the M-wave duration markedly increased during the recovery period. CONCLUSIONS: The response of CFS patients to incremental exercise associates a lengthened and accentuated oxidative stress together with marked alterations of the muscle membrane excitability. These two objective signs of muscle dysfunction are sufficient to explain muscle pain and postexertional malaise reported by our patients. 149 PMID- 15929497 AU - Jason LA, Corradi K, Torres-Harding S, Taylor RR, King C TI - CFS: the need for subtypes. SO - Neuropsychol Rev. 2005 Mar;15(1):29-58. IN - DePaul U, Chicago, Illinois 60614, USA. ljason@depaul.edu AB - Chronic fatigue syndrome (CFS) is an important condition confronting patients, clinicians, and researchers. This article provides information concerning the need for appropriate diagnosis of CFS subtypes. We first review findings suggesting that CFS is best conceptualized as a separate diagnostic entity rather than as part of a unitary model of functional somatic distress. Next, research involving the case definitions of CFS is reviewed. Findings suggest that whether a broad or more conservative case definition is employed, and whether clinic or community samples are recruited, these decisions will have a major influence in the types of patients selected. Review of further findings suggests that subtyping individuals with CFS on sociodemographic, functional disability, viral, immune, neuroendocrine, neurology, autonomic, and genetic biomarkers can provide clarification for researchers and clinicians who encounter CFS' characteristically confusing heterogeneous symptom profiles. Treatment studies that incorporate subtypes might be particularly helpful in better understanding the pathophysiology of CFS. This review suggests that there is a need for greater diagnostic clarity, and this might be accomplished by subgroups that integrate multiple variables including those in cognitive, emotional, and biological domains. 150 PMID- 15922454 AU - Jerjes WK, Cleare AJ, Wessely S, Wood PJ, Taylor NF TI - Diurnal patterns of salivary cortisol & cortisone output in CFS.

METHOD: Cortisol and cortisone levels were measured in saliva samples collected from 0600 h to 2100 h at 3-h intervals in CFS patients and healthy controls. RESULTS: Mean cortisol and cortisone concentrations were significantly lower in patients than controls across the whole day, as were levels at each individual time point except 2100 h. Cosinor analysis showed a significant diurnal rhythm of cortisol and cortisone that was not phase-shifted in CFS compared to controls. However, there was a lower rhythm-adjusted mean and a lower amplitude in CFS patients. The cortisol/cortisone ratio showed no diurnal rhythm and did not differ between CFS subjects and controls. LIMITATIONS: The sample size was relatively small, and drawn from specialist referral patients who had been ill for some time; generalisation of these results to other populations is therefore unwarranted. CONCLUSION: The main findings of this study are to provide further evidence for reduced basal HPA axis function in at least some patients with CFS and to show for the first time that salivary cortisone is also reduced in CFS and has a diurnal rhythm similar to that of cortisol. We have also demonstrated that the cortisol/cortisone ratio remains unchanged in CFS, suggesting that increased conversion of cortisol to cortisone cannot account for the observed lowering of salivary cortisol. 151 PMID- 16378795 AU - Jones JF, Nicholson A, Nisenbaum R, Papanicolaou DA, Solomon L, Boneva R, Heim C, Reeves WC TI - Orthostatic instability in a population-based study of CFS.

IN - Division o Viral & Rickettsial Diseases, Nat Ctr for Infectious Diseases, Centers for Disease Control & Prevention, Atlanta, Ga 30333, USA. jaj9@cdc.gov AB - PURPOSE: Autonomic nervous system dysfunction has been suggested as involved in the pathophysiology of chronic fatigue syndrome. This population-based case control study addressed the potential association between orthostatic instability (one sign of dysautonomia) and chronic fatigue syndrome. SUBJECTS AND METHODS: Fifty-eight subjects who fulfilled criteria of the 1994 chronic fatigue syndrome research case definition and 55 healthy controls participated in a 2-day inpatient evaluation. Subjects had been identified during a 4-year population-based chronic fatigue syndrome surveillance study in Wichita, Kan. The present study evaluated subjects' current medical and psychiatric status, reviewed past medical/psychiatric history and medication use, used a stand-up test to screen for orthostatic instability, and conducted a head-up tilt table test to diagnose orthostatic instability. RESULTS: No one manifested orthostatic instability in the stand-up test. The head-up tilt test elicited orthostatic instability in 30% of eligible chronic fatigue syndrome subjects (all with postural orthostatic tachycardia) and 48% of controls (50% with neurally mediated hypotension); intolerance was present in only nonfatigued (n=7) subjects. Neither fatigue nor illness severity were associated with outcome. CONCLUSIONS: Orthostatic instability was similar in persons with chronic fatigue syndrome and nonfatigued controls subjects recruited from the general Wichita population. Delayed responses to head-up tilt tests were common and may reflect hydration status. These findings suggest reappraisal of primary dysautonomia as a factor in the pathogenesis of chronic fatigue syndrome. 152 PMID- 15967423 AU - Jones MG, Goodwin CS, Amjad S, Chalmers RA TI - Plasma & urinary carnitine & acylcarnitines in CFS. SO - Clin Chim Acta. 2005 Oct;360(1-2):173-7. IN - St. George's Hosp MS, Cranmer Terrace, London, SW17 0RE, UK. AB - Contradictory reports have suggested that serum free carnitine and acylcarnitine concentrations are decreased in patients with chronic fatigue syndrome (CFS) and that this is a cause of the muscle fatigue observed in these patients. Others have shown normal serum free carnitine and acylcarnitines in similar patients. We report here studies on free, total and esterified (acyl) carnitines in urine and blood plasma from UK patients with CFS and three control groups. Plasma and timed urine samples were obtained from 31 patients with CFS, 31 healthy controls, 15 patients with depression and 22 patients with rheumatoid arthritis. Samples were analysed using an established radioenzymatic procedure for total, free and esterified (acyl) carnitine. There were no significant differences in plasma or urinary total, free or esterified (acyl) carnitine between UK patients with CFS and the control groups or in renal excretion rates of these compounds. The data presented here show that, in the CFS patients studied, there are no significant abnormalities of free or esterified (acyl) carnitine. It is thus unlikely that abnormalities in carnitine homeostasis have any significant role in the aetiology of their chronic fatigue. 153 PMID- 15992788 AU - Jones MG, Cooper E, Amjad S, Goodwin CS, Barron JL, Chalmers RA TI - Urinary & plasma organic acids & amino acids in CFS. SO - Clin Chim Acta. 2005 Nov;361(1-2):150-8. IN - St George's Hosp MS, Cranmer Terrace, London, SW17 0RE, UK. AB - Previous work by others have suggested the occurrence of one or more chemical or metabolic 'markers' for ME/CFS including specific amino acids and organic acids and a number of unidentified compounds (CFSUM1, CFSUM2). We have shown elsewhere that CFSUM1 is partially derivatised pyroglutamic acid and CFSUM2 partially derivatised serine and have suggested and demonstrated that the analytical methods used were unsuitable to identify or to accurately quantify urinary metabolites. We have now made a detailed analysis of plasma and urinary amino acids and of urinary organic acids from patients with ME/CFS and from three control groups. Fasting blood plasma and timed urine samples were obtained from 31 patients with CFS, 31 age and sex-matched healthy controls, 15 patients with depression and 22 patients with rheumatoid arthritis. Plasma and urinary amino acids and urinary organic acids were determined using established and validated methods and data compared by statistical analysis. None of the previously reported abnormalities in urinary amino acids or of organic acids could be confirmed. Results however provide some evidence in patients with ME/CFS for underlying inflammatory disease and for reduced intramuscular collagen with a lowered threshold for muscle micro-injury. These factors in combination may provide a basis for the fatigue and muscle pain that are the major symptoms in these patients. 154 PMID- 16119758 AU - Jowi JO, Gathua SN TI - Lyme disease: report of 2 cases.

It was first described in Lyme, Connecticut, USA in 1975. Cases have been reported in Canada, Switzerland, Austria, Australia and Great Britain. It is an inflammatory disease that has varied clinical manifestations ranging from skin rash (erythema migrans), arthritis, fibromyalgia, and regional lymphadenopathy, cardiac conduction defects to neurological manifestations of meningoencephalitis, Bell's palsy, peripheral neuropathy, and painful radiculoneuropathy. There has been no case record of Lyme disease in Kenya and indeed literature on Lyme disease in Africa is very scanty. We present two cases of Lyme disease with predominant neurological manifestations; outline their clinical presentation and management. 155 PMID- 15733656 AU - Julien N, Goffaux P, Arsenault P, Marchand S TI - Widespread pain in FM is related to a deficit of endogenous pain inhibition. SO - Pain. 2005 Mar;114(1-2):295-302. IN - Departement des Sciences de la Sante, Universite du Quebec en Abitibi-Temiscamingue, Rouyn-Noranda, Que., Canada. AB - A deficit of endogenous pain inhibitory systems has been suggested to contribute to some chronic pain conditions, one of them being fibromyalgia. The aim of the investigation was to test whether endogenous pain inhibitory systems were activated by a spatial summation procedure in 30 fibromyalgia, 30 chronic low back pain, and 30 healthy volunteers who participated in a cross-over trial (two sessions). Each session consisted of visual analog scale ratings of pain during the immersion of different surfaces of the arm in circulating noxious cold (12 degrees C) water. The arm was arbitrarily divided into eight segments from the fingertips to the shoulder. One session was ascending (from the fingertips to the shoulder) and the other was descending (from the shoulder to the fingertips); they included eight consecutive 2-min immersions separated by 5-min resting periods. For healthy and low back pain subjects, pain was perceived differently during the ascending and descending sessions (P=0.0001). The descending session resulted in lower pain intensity and unpleasantness. This lowering of the perception curve seems to be due to a full recruitment of inhibitory systems at the beginning of the descending session as opposed to a gradual recruitment during the ascending session. For fibromyalgia subjects, no significant differences were found between the increasing and decreasing sessions (P>0.05). These data support a deficit of endogenous pain inhibitory systems in fibromyalgia but not in chronic low back pain. The treatments proposed to fibromyalgia patients should aim at stimulating the activity of those endogenous systems. 156 PMID- 16009053 AU - Karmisholt K, Gotzsche PC TI - Physical activity for secondary prevention of disease. Systematic reviews of randomised clinical trials. [CFS] SO - Dan Med Bull. 2005 May;52(2):90-4. IN - Nordic Cochrane Centre, H:S Rigshospitalet, DK-2100 Kobenhavn O, Denmark. AB - BACKGROUND: Physical activity is recommended for secondary prevention of several diseases but it is not always clear how reliable the evidence is. METHODS: We searched MEDLINE and The Cochrane Library for systematic reviews of randomised clinical trials published 1998-2004. RESULTS: We identified 30 eligible systematic reviews and excluded 13 that contained trials covered in larger reviews or were older than other reviews on the same subject. Physical activity decreased all-cause mortality in patients with coronary heart disease, odds ratio 0.73 (95% confidence interval 0.54 to 0.98), increased maximum walking time in patients with intermittent claudication by 6.5 min (4.4 to 8.7), and decreased pain in patients with osteoarthritis of the knee, standardised mean difference 0.34 (0.24 to 0.44). There were positive effects also in heart failure, chronic obstructive lung disease, type 2 diabetes and fibromyalgia, but they need confirmation in high-quality trials. Exercise improved quality of life in several conditions and generally led to improved physical performance. An effect was not shown in stroke, asthma, rheumatoid arthritis, acute or chronic low back pain, chronic fatigue syndrome, depression, cystic fibrosis or HIV/AIDS. The occurrence of harms was generally not reported. CONCLUSION: Physical activity can have important, and even life-saving, effects as secondary prevention of disease, but more and better trials are needed to fully assess its benefits and harms, in particular trials that compare exercise with drugs. 157 PMID- 16078340 AU - Kashikar-Zuck S, Swain NF, Jones BA, Graham TB TI - Efficacy of cognitive-behavioral intervention for juvenile primary FM syndrome.

Susmita.Kashikar-Zuck@cchmc.org AB - OBJECTIVE: There are currently no controlled studies of behavioral interventions for juvenile primary fibromyalgia syndrome (JPFM). In this small-sample randomized study, we tested the efficacy of a behavioral intervention, i.e., coping skills training (CST), for the treatment of adolescents with JPFM. Outcomes tested in this study were functional disability, pain intensity, pain-coping efficacy, and depressive symptoms. METHODS: Thirty patients with JPFM were randomly assigned to 8 weeks of either CST or self-monitoring. Adolescents in the CST condition received training in active pain-coping techniques, while those in the self-monitoring condition monitored daily pain intensity and sleep quality with no instructions about behavior change. After posttreatment assessment, subjects were crossed over into the opposite treatment arm for 8 weeks (so that all adolescents eventually received both CST and self-monitoring) and were reassessed at Week 16. RESULTS: At Week 8, adolescents in both conditions showed significant decrease in depressive symptoms and functional disability. Those who received CST showed significantly greater ability to cope with pain than those in the self-monitoring condition and a trend toward decreased pain intensity. At Week 16, adolescents had significantly lower levels of disability and depressive symptoms compared to baseline, but those who received self-monitoring followed by CST seemed to receive the most benefit. CONCLUSION: CST can lead to improved functioning among JPFM patients. Although some of the improvement may be due to increased monitoring and attention, CST provides the specific benefit of improving adolescents' ability to cope with pain. 158 PMID- 16049284 AU - Kaushik N, Fear D, Richards SC, McDermott CR, Nuwaysir EF, Kellam P, Harrison TJ, Wilkinson RJ, Tyrrell DA, Holgate ST, Kerr JR TI - Gene expression in peripheral blood mononuclear cells from pts w CFS. SO - J Clin Pathol. 2005 Aug;58(8):826-32. IN - D o Paediatric Infectious Diseases, St Marys Campus, Imperial Coll, Norfolk Place, London W2 1PG, UK. AB - BACKGROUND: Chronic fatigue syndrome (CFS) is a multisystem disease, the pathogenesis of which remains undetermined. AIMS: To test the hypothesis that there are reproducible abnormalities of gene expression in patients with CFS compared with normal healthy persons. METHODS: To gain further insight into the pathogenesis of this disease, gene expression was analysed in peripheral blood mononuclear cells from 25 patients with CFS diagnosed according to the Centers for Disease Control criteria and 25 normal blood donors matched for age, sex, and geographical location, using a single colour microarray representing 9522 human genes. After normalisation, average difference values for each gene were compared between test and control groups using a cutoff fold difference of expression > or = 1.5 and a p value of 0.001. Genes showing differential expression were further analysed using Taqman real time polymerase chain reaction (PCR) in fresh samples. RESULTS: Analysis of microarray data revealed differential expression of 35 genes. Real time PCR confirmed differential expression in the same direction as array results for 16 of these genes, 15 of which were upregulated (ABCD4, PRKCL1, MRPL23, CD2BP2, GSN, NTE, POLR2G, PEX16, EIF2B4, EIF4G1, ANAPC11, PDCD2, KHSRP, BRMS1, and GABARAPL1) and one of which was downregulated (IL-10RA). This profile suggests T cell activation and perturbation of neuronal and mitochondrial function. Upregulation of neuropathy target esterase and eukaryotic translation initiation factor 4G1 may suggest links with organophosphate exposure and virus infection, respectively. CONCLUSION: These results suggest that patients with CFS have reproducible alterations in gene regulation. 159 PMID- 16085177 AU - Kennedy G, Spence VA, McLaren M, Hill A, Underwood C, Belch JJ TI - Oxidative stress levels are raised in CFS & are associated w clinical Sx.

IN - Vascular Diseases Research Unit, The Inst o Cardiovascular Research, Ninewells Hosp & MS, Dundee, Scotland DD1 9SY, UK. g.y.kennedy@dundee.ac.uk AB - The aetiology of chronic fatigue syndrome (CFS) is unknown; however, recent evidence suggests excessive free radical (FR) generation may be involved. This study investigated for the first time levels of 8-iso-prostaglandin-F(2 alpha)-isoprostanes alongside other plasma markers of oxidative stress in CFS patients and control subjects. Forty-seven patients (18 males, 29 females, mean age 48 [19--63] years) who fulfilled the Centres for Disease Control classification for CFS and 34 healthy volunteers (13 males, 21 females, 46 [19--63] years) were enrolled in the study. The CFS patients were divided into two groups; one group had previously defined cardiovascular (CV) risk factors of obesity and hypertension (group 1) and the second were normotensive and nonobese (group 2). Patients had significantly increased levels of isoprostanes (group 1, P=0.007; group 2, P=0.03, unpaired t test compared to controls) and oxidised low-density lipoproteins (group 2, P=0.02) indicative of a FR attack on lipids. CFS patients also had significantly lower high-density lipoproteins (group 1, P=0.011; group 2, P=0.005). CFS symptoms correlated with isoprostane levels, but only in group 2 low CV risk CFS patients (isoprostanes correlated with; total symptom score P=0.005; joint pain P=0.002; postexertional malaise P=0.027, Pearson). This is the first time that raised levels of the gold standard measure of in vivo oxidative stress (isoprostanes) and their association with CFS symptoms have been reported. 160 PMID- 16316396 AU - Kerr JR TI - Pathogenesis of parvovirus B19 infection: host gene variability, & possible means & effects of virus persistence. [CFS] SO - J Vet Med B Infect Dis Vet Public Health. 2005 Sep-Oct;52(7-8):335-9. IN - D o Cellular & Molecular Med, St George's U o London, Cranmer Terrace, London SW17 0RE, UK. jkerr@sgul.ac.uk AB - Since conducting follow-up studies of patients with acute symptomatic parvovirus B19 infection which showed that a significant proportion of patients develop prolonged arthritis and chronic fatigue syndrome (CFS), we have become interested in the mechanisms of this phenomenon. We showed that these cases have high levels of pro-inflammatory cytokines in their circulation and that this correlates with the symptoms. However, the underlying mechanisms were not apparent, and we have used various approaches to begin studying this phenomenon. DNA polymorphisms were looked for and several were shown to be more common in these subjects compared with controls; these occur within genes of both the immune response [human leucocyte antigen (HLA)-DRB1, HLA-B, transforming growth factor (TGF)-beta1] and those involved in several other cellular functions (predominantly the cytoskeleton and cell adhesion). Interestingly, one particular single-nucleotide polymorphism (SNP) which is associated with symptomatic B19 infection occurs in the Ku80 gene which has recently been shown to be a B19 co-receptor. B19 persistence is probably the key to this phenomenon, and some new data are presented on short regions of sequence homology (17-26 bp) between human, mouse and rat parvoviruses and their respective hosts which occur in many host genes. This homology may provide a foothold for virus persistence and may also play a role in the genesis of disease through gene disruption. Finally, we used microarrays and TaqMan real-time polymerase chain reaction in 108 normal persons to study human gene expression in persons who are B19-seropositive versus B19-seronegative (age- and sex-matched) to examine the hypothesis that gene regulation may be altered in subjects harbouring the B19 virus DNA. Six genes were found to be differentially expressed with roles in the cytoskeleton (SKIP, MACF1, SPAG7, FLOT1), integrin signalling (FLOT1, RASSF5), HLA class III (c6orf48), and tumour suppression (RASSF5). These results have implications not only for B19 but also for other persistent viruses as well and confirmation is required. In conclusion, these disparate findings contribute to our understanding of the pathogenesis of B19 disease. We are using these studies as a starting point to study the phenomenon of chronic immune activation following B19 infection. 161 PMID- 16100439 AU - Kim CH, Shin HC, Won CW TI - Prevalence of chr fatigue & CFS in Korea: community-based primary care study. SO - J Korean Med Sci. 2005 Aug;20(4):529-34. IN - D o Family Med, Sungkyunkwan U School o Medicine, Korea. kchjp@hanafos.com AB - There have been many epidemiological and clinical researches on chronic fatigue (CF) and chronic fatigue syndrome (CFS) since the 1990s, but such studies have been quite limited in Korea. The aim of this study was to investigate the point prevalence of CF and CFS in patients who visited community-based eight primary care clinics in Korea. The study subjects were 1,648 patients aged 18 yr and over who visited one of eight primary care clinics in Korea between the 7th and 17th of May 2001. The physicians determined the status of the subjects through fatigue-related questionnaires, medical history, physical examination, and laboratory tests. The subjects were categorized into no fatigue, prolonged fatigue, CF and then CF were further classified to medically explained CF (Physical CF and Psychological CF) and medically unexplained CF (CFS and idiopathic chronic fatigue). The point prevalence of CF and CFS were 8.4% (95% CI 7.1-9.7%) and 0.6% (95% CI 0.2-1.0%). Medically explained CF was 80.5% of CF, of which 57.1% had psychological causes. The clinical characteristics of CFS were distinguished from explained CF. CF was common but CFS was rare in community-based primary care settings in Korea. 162 PMID- 15450690 AU - King C, Jason LA TI - Improving the diagnostic criteria & procedures for CFS.

Box 5000, Hines, IL 60141-5128, USA. cpking@rcn.com AB - Since the publication of the case definition for chronic fatigue syndrome (CFS) in 1988 the diagnostic criteria have been revised twice in the U.S. None of the case definitions were derived empirically. As a result, there is concern regarding the sensitivity, specificity, and reliability of the criteria. The goal of the present study was to identify methods for improving the diagnostic criteria for CFS. Three groups of 15 participants each were recruited: participants with (1) CFS, (2) major depressive disorder (MDD), and (3) healthy controls. Using statistical procedures, three methods for improving the diagnostic criteria were explored: identification of new diagnostic symptoms, the use of severity ratings for symptomatology, and the identification of standardized measures that differentiate cases of CFS from other conditions. Results of the present study suggest that these three methods hold promise for improving the sensitivity, specificity, and reliability of the diagnostic criteria for CFS. 163 PMID- 16181932 AU - Kingsley JD, Panton LB, Toole T, Sirithienthad P, Mathis R, McMillan V TI - The effects of a 12-week strength-training program on strength & functionality in women w FM.

AB - OBJECTIVE: To determine whether women with fibromyalgia benefit from strength training. DESIGN: Randomized controlled trial. SETTING: Testing was completed at the university and training was completed at a local community wellness facility. PARTICIPANTS: Twenty-nine women (age range, 18-54 y) with fibromyalgia participated. Subjects were randomly assigned to a control (n=14; wait-listed for exercise) or strength (n=15) group. After the first 4 weeks, 7 (47%) women dropped from the strength group. INTERVENTION: Subjects underwent 12 weeks of training on 11 exercises, 2 times a week, performing 1 set of 8 to 12 repetitions at 40% to 60% of their maximal lifts and were progressed to 60% to 80%. MAIN OUTCOME MEASURES: Subjects were measured for strength, functionality, tender point sensitivity, and fibromyalgia impact. RESULTS: The strength group significantly (P< or =.05) improved upper- (strength, 39+/-11 to 42+/-12 kg; control, 38+/-13 to 38+/-12 kg) and lower- (strength, 68+/-28 to 82+/-25 kg; control, 61+/-25 to 61+/-26 kg) body strength. Upper-body functionality measured by the Continuous-Scale Physical Functional Performance test improved significantly (strength, 44+/-11 to 50+/-16U; control, 51+/-11 to 49+/-13U) after training. Tender point sensitivity and fibromyalgia impact did not change. CONCLUSIONS: Strength training improved strength and some functionality in women with fibromyalgia. Interventions with resistance have important implications on independence and quality of life issues for women with fibromyalgia. 164 PMID- 15583836 AU - Kodama M, Kodama T TI - The clinical course of interstitial pneumonia alias CFS under the control of megadose vitamin C infusion system w dehydroepiandrosterone-cortisol annex.

AB - The year 1995 marked the onset of interstitial pneumonia spread in Nagoya, Japan. For the last 9 years, we have been accumulating clinical experience with the disease control using the combination of prophylactic use of anti-biotics and regular practice of megadose vitamin C infusion with either dehydroepiandrosterone-annex or dehydroepiandrosterone-cortisol annex. The purpose of this study is to assess the usefulness of our new treatment system for the control of interstitial pneumonia alias chronic fatigue syndrome. The results obtained are given as follows: i) The long-term maintenance of the above treatment system was effective not only for decreasing the risk for recurrence of active form pneumonia, but also for prevention of malignancy emergence in aged patients with interstitial pneumonia. ii) Evidence is presented to indicate that interstitial pneumonia was associated with increased risk for depression of which the emergence is a candidate subject causally related to the long-term use of glucocorticoid. iii) A patient with both interstitial pneumonia and depression was found to be less responsive to our treatment system. It is suggested that the use of more dehydroepiandrosterone at the sacrifice of cortisol in the infusion annex may be a choice for the control of both interstitial pneumonia and depression. iv) The description of chronic fatigue syndrome as regards the endocrinological, epidemiological and psychiatric characteristics are in good agreement with our experience on patients having interstitial pneumonia, evidence in support of our proposal that there is no convincing reasoning to separate chronic fatigue syndrome from interstitial pneumonia. v) The long-term practice of our treatment system for the control of interstitial pneumonia (an autoimmune disease) was found to suppress the inflammatory process but not the fibrotic process in the long run. vi) A few innovations were made in our treatment system to reduce the risk of bleeding or thrombosis--vascular complications of pneumonia. vii) The merit of our treatment system is to create a new hormonal environment to improve the state of immunodeficiency by use of a non-steroid substance--vitamin C which encounters little resistance from the feedback mechanism of steroid metabolism in the in vivo system. 165 PMID- 15641057 AU - Kop WJ, Lyden A, Berlin AA, Ambrose K, Olsen C, Gracely RH, Williams DA, Clauw DJ TI - Ambulatory monitoring of physical activity & Sx in FM & CFS.

Determinants of self-reported physical disability are poorly understood. This investigation uses objective ambulatory activity monitoring to compare patients with FM and/or CFS with controls, and examines associations of ambulatory activity levels with both physical function and symptoms during activities of daily life. METHODS: Patients with FM and/or CFS (n = 38, mean +/- SD age 41.5 +/- 8.2 years, 74% women) completed a 5-day program of ambulatory monitoring of physical activity and symptoms (pain, fatigue, and distress) and results were compared with those in age-matched controls (n = 27, mean +/- SD age 38.0 +/- 8.6 years, 44% women). Activity levels were assessed continuously, ambulatory symptoms were determined using electronically time-stamped recordings at 5 time points during each day, and physical function was measured with the 36-item Short Form health survey at the end of the 5-day monitoring period. RESULTS: Patients had significantly lower peak activity levels than controls (mean +/- SEM 8,654 +/- 527 versus 12,913 +/- 1,462 units; P = 0.003) and spent less time in high-level activities when compared with controls (P = 0.001). In contrast, patients had similar average activity levels as those of controls (mean +/- SEM 1,525 +/- 63 versus 1,602 +/- 89; P = 0.47). Among patients, low activity levels were associated with worse self-reported physical function over the preceding month. Activity levels were inversely related to concurrent ambulatory pain (P = 0.031) and fatigue (P < 0.001). Pain and fatigue were associated with reduced subsequent ambulatory activity levels, whereas activity levels were not predictive of subsequent symptoms. CONCLUSION: Patients with FM and/or CFS engaged in less high-intensity physical activities than that recorded for sedentary control subjects. This reduced peak activity was correlated with measures of poor physical function. The observed associations may be relevant to the design of behavioral activation programs, because activity levels appear to be contingent on, rather than predictive of, symptoms. 166 PMID- 16145181 AU - Krell HV, Leuchter AF, Cook IA, Abrams M TI - Evaluation of reboxetine, a noradrenergic antidepressant, for the Rx of FM & chr low back pain.

Although this use of antidepressants is common in clinical practice, the literature supporting this off-label use has some limitations. In this report, the authors review the body of clinical data on the use of antidepressants in treating pain and present a case series of depressed patients with these syndromes who experienced relief of pain symptoms while being treated with the noradrenergic antidepressant reboxetine. These subjects experienced significant relief of pain before any significant improvement in actual mood symptoms. Our experience with reboxetine suggests that this noradrenergic antidepressant may have efficacy in the treatment of chronic pain in patients with depression. 167 PMID- 16247056 AU - Kwan CL, Diamant NE, Pope G, Mikula K, Mikulis DJ, Davis KD TI - Abnormal forebrain activity in functional bowel disorder pts w chr pain. [FM] SO - Neurology. 2005 Oct 25;65(8):1268-77. IN - Institute o Med Science, U o Toronto, Ontario, Canada. AB - BACKGROUND: Abnormal cortical pain responses in patients with fibromyalgia and conversion disorder raise the possibility of a neurobiologic basis underlying so-called "functional" chronic pain. OBJECTIVE: To use percept-related fMRI to test the hypothesis that patients with a painful functional bowel disorder do not process visceral input or sensations normally or effectively at the cortical level. METHODS: Eleven healthy subjects and nine patients with irritable bowel syndrome (IBS) underwent fMRI during rectal distensions that elicited either a moderate level of urge to defecate or pain. Subjects continuously rated their rectal stimulus-evoked urge or pain sensations during fMRI acquisition. fMRI data were interrogated for activity related to stimulus presence and to specific sensations. RESULTS: In IBS, abnormal responses associated with rectal-evoked sensations were identified in five brain regions. In primary sensory cortex, there were urge-related responses in the IBS but not control group. In the medial thalamus and hippocampus, there were pain-related responses in the IBS but not control group. However, pronounced urge- and pain-related activations were present in the right anterior insula and the right anterior cingulate cortex in the control group but not the IBS group. CONCLUSIONS: Percept-related fMRI revealed abnormal urge- and pain-related forebrain activity during rectal distension in patients with irritable bowel syndrome (IBS). As visceral stimulation evokes pain and triggers unconscious processes related to homeostasis and reflexes, abnormal brain responses in IBS may reflect the sensory symptoms of rectal pain and hypersensitivity, visceromotor dysfunction, and abnormal interoceptive processing. 168 PMID- 16175250 AU - Lam DK, Sessle BJ, Cairns BE, Hu JW TI - Neural mechanisms of temporomandibular joint & masticatory muscle pain: a possible role for peripheral glutamate receptor mechanisms.

Chronic pain is common, and many people suffer from chronic pain conditions involving deep craniofacial tissues such as temporomandibular disorders or fibromyalgia. Animal and human studies have indicated that the activation of peripheral ionotropic glutamate receptors in deep craniofacial tissues may contribute to muscle and temporomandibular joint pain and that sex differences in the activation of glutamate receptors may be involved in the female predominance in temporomandibular disorders and fibromyalgia. A peripheral mechanism involving autocrine and/or paracrine regulation of nociceptive neuronal excitability via injury or inflammation-induced release of glutamate into peripheral tissues that may contribute to the development of craniofacial pain is proposed. 169 PMID- 15907308 AU - Lange G, Steffener J, Cook DB, Bly BM, Christodoulou C, Liu WC, Deluca J, Natelson BH TI - Objective evidence of cognitive complaints in CFS: a BOLD fMRI study of verbal working memory.

IN - D o Radiology, U o Med & Dentistry o New Jersey-New Jersey MS, Newark, 07103, USA. lange@njneuromed.org AB - Individuals with Chronic Fatigue Syndrome (CFS) often have difficulties with complex auditory information processing. In a series of two Blood Oxygen Level Dependent (BOLD) functional Magnetic Resonance Imaging (fMRI) studies, we compared BOLD signal changes between Controls and individuals with CFS who had documented difficulties in complex auditory information processing (Study 1) and those who did not (Study 2) in response to performance on a simple auditory monitoring and a complex auditory information processing task (mPASAT). We hypothesized that under conditions of cognitive challenge: (1) individuals with CFS who have auditory information processing difficulties will utilize frontal and parietal brain regions to a greater extent than Controls and (2) these differences will be maintained even when objective difficulties in this domain are controlled for. Using blocked design fMRI paradigms in both studies, we first presented the auditory monitoring task followed by the mPASAT. Within and between regions of interest (ROI), group analyses were performed for both studies with statistical parametric mapping (SPM99). Findings showed that individuals with CFS are able to process challenging auditory information as accurately as Controls but utilize more extensive regions of the network associated with the verbal WM system. Individuals with CFS appear to have to exert greater effort to process auditory information as effectively as demographically similar healthy adults. Our findings provide objective evidence for the subjective experience of cognitive difficulties in individuals with CFS. 170 PMID- 15862476 AU - Laursen BS, Bajaj P, Olesen AS, Delmar C, Arendt-Nielsen L TI - Health related quality of life & quantitative pain measurement in females w chr non-malignant pain. [FM] SO - Eur J Pain. 2005 Jun;9(3):267-75. IN - Clinical Nursing Research Unit, Aalborg Hosp Stengade 10, Denmark. AB - The aim of the present study was to assess, compare, and correlate the pain response to an experimental pain stimulus (hyperalgesia to pressure pain threshold (PPT) measured from different body sites), the pain intensity (VAS) of the habitual pain, and quality of life parameters (SF-36) in groups of females with chronic non-malignant pain syndromes. Forty female pain patients with fibromyalgia/whiplash (n = 10), endometriosis (n = 10), low back pain (n = 10), or rheumatoid arthritis (n = 10), as well as 41 age-matched healthy female controls participated in the study. The fibromyalgia/whiplash patients scored significantly higher (p < 0.04) VAS ratings (median rating = 7.0) than the endometriosis (6.0), low back pain (6.0), and rheumatoid arthritis (3.5) patients. All fours patient groups had significantly lower PPTs at all sites as compared with controls. The fibromyalgia/whiplash patients experienced the highest influence of pain on their overall health status, particularly vitality, social function, emotional problems, and mental health. A significant negative correlation was found between VAS rating and quality of life (p < 0.04). Significant correlation (p < 0.05) was found between pressure hyperalgesia measured at lowest PPT sites and the impairment of SF-36 physical function as well as mental health parameters. This study demonstrates significant generalised pressure hyperalgesia in four groups of chronic pain patients, correlations between degree of pressure hyperalgesia and impairment of some quality of life parameters, and increased pain intensity of the ongoing pain is associated with decreased quality of life. 171 PMID- 15779535 AU - Lavigne G, Woda A, Truelove E, Ship JA, Dao T, Goulet JP TI - Mechanisms associated w unusual orofacial pain.

It includes recent evidence concerning neurobiological changes that occur in the periphery at tissue and nerve sites, or within the central nervous system, and that may involve chemical and inflammatory responses, sensitization, or alterations of cellular function. Moreover, the contribution of the autonomic nervous system, changes in emotional reactivity and vigilance, the roles of high brain centers such as the basal ganglia (nigro-striatal) system, and the influence of aging and gender, are briefly described. 172 PMID- 16273759 AU - Lee SS, Yoon HJ, Chang HK, Park KS TI - FM in Behcet's disease is associated w anxiety & depression, & not w disease activity.

METHODS: Seventy patients with BD were examined for FM tender points and asked to complete a Korean version of the Fibromyalgia Impact Questionnaire (FIQ). Disease activity was measured using the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and a clinical activity score, which was calculated by summing the clinical manifestations. The State-Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI) were used for psychometric scoring. RESULTS: Twenty-six BD patients (37.1%) met the American College of Rheumatology criteria for FM. The patients who met the criteria for FM were more frequently female, less frequently employed, and less well educated. Age, disease duration, clinical manifestations, medication, and measures of disease activity did not differ between BD patients with and without FM. Nevertheless, BD patients with FM had higher STAI and BDI scores than did patients without FM (all p < 0.05). FM tender points were significantly correlated with the STAI and BDI, and not with disease activity variables. The FIQ scores were also strongly correlated with the STAI and BDI scores, and not with disease activity. CONCLUSION: FM was very common among BD patients and was associated with the presence of anxiety and depression, and not with disease activity. 173 PMID- 15722810 AU - Lemstra M, Olszynski WP TI - The effectiveness of multidisciplinary rehabilitation in the Rx of FM: a randomized controlled trial.

AB - OBJECTIVES: To assess the effectiveness of multidisciplinary rehabilitation in the treatment of fibromyalgia in comparison to standard medical care. METHODS: Seventy-nine men and women were randomly assigned to one of two groups. The intervention group consisted of a rheumatologist and physical therapist intake and discharge, 18 group supervised exercise therapy sessions, 2 group pain and stress management lectures, 1 group education lecture, 1 group dietary lecture, and 2 massage therapy sessions. The control group consisted of standard medical care with the patients' family physician. Outcome measures included self-perceived health status, pain-related disability, average pain intensity, depressed mood, days in pain, hours in pain, prescription and nonprescription medication usage, and work status. Outcomes were measured at the end of the 6-week intervention and at 15-month follow-up. RESULTS: Thirty-five out of 43 patients from the intervention group and 36 out of 36 patients from the control group completed the study. There were no statistically significant differences between the 2 groups prior to intervention. Intention-to-treat analysis revealed that the intervention group, in comparison to the control group, experienced statistically significant changes at intervention completion in self-perceived health status, average pain intensity, pain related disability, depressed mood, days in pain, and hours in pain, but no significant differences in nonprescription drug use, prescription drug use, or work status. At 15 months, all health outcomes retained their significance except health status. Nonprescription and prescription drug use demonstrated significant reductions at 15 months. Binary logistic regression indicated that long-term changes in Pain Disability Index were influenced by long-term exercise adherence and income status. CONCLUSIONS: Positive health-related outcomes in this mostly unresponsive condition can be obtained with a low-cost, group multidisciplinary intervention in a community-based, nonclinical setting. 174 PMID- 16078358 AU - Levine JD, Reichling DB TI - FM: the nerve of that disease.

Levine@itsa.ucsf.edu AB - Fibromyalgia syndrome (FM) is a common, often debilitating and intractable, chronic, generalized pain condition. The development of effective therapies to treat FM has been hindered by a lack of understanding of fundamental mechanisms in the etiology of FM. In view of prominent characteristics that FM shares with other generalized pain conditions, we suggest that a key mechanism in such disorders may be that of altered activity in the subdiaphragmatic vagus nerve. Specifically, we propose that activity in vagal afferents, arising from the gastrointestinal tract, and sympathoadrenal function mediate a contribution of stress to FM and its strong association with irritable bowel syndrome. An important prediction of the proposed mechanism is that interventions that selectively modulate activity in specific populations of subdiaphragmatic afferents might be used to treat the symptoms of FM and other generalized pain syndromes. 175 PMID- 15737168 AU - Liedberg GM, Burckhardt CS, Henriksson CM TI - Validity & reliability testing of the Quality of Life Scale, Swedish version in women w FM -- statistical analyses.

The purpose of the study was to examine whether the Quality of Life Scale, Swedish version (QOLS-S), regarded as a generic quality-of-life instrument, is a reliable and valid instrument for use in women with fibromyalgia (FM). Women with FM (n = 113) contributed data on the QOLS-S and other standardized instrument at three points in time. Internal consistency reliability estimates ranged from 0.89 to 0.92. Convergent construct validity was indicated by moderate agreement with a global life satisfaction question. Discriminant construct validity was denoted by low correlations with the physical functioning subscale of the SF-36. In a factor analysis three factors emerged: 'personal and social well-being', 'relations with others' and 'active participation'. A few of the items have high cross-loadings, and the instrument could be improved by rewording those items to more closely reflect one specific factor. Overall, these results provide evidence that the QOLS-S has acceptable validity and reliability for use in women with FM. 176 PMID- 15970921 AU - Luedtke CA, Thompson JM, Postier JA, Neubauer BL, Drach S, Newell L TI - A description of a brief multidisciplinary Rx program for FM. SO - Pain Manag Nurs. 2005 Jun;6(2):76-80. IN - Fibromyalgia Treatment Program, Mayo Clinic, Rochester, Minnesota, USA. Luedtke.connie@Mayo.edu AB - The majority of fibromyalgia treatment programs are weeks or months in duration. This tertiary care center draws people worldwide for diagnostic purposes; however, most patients are unable to stay for extended treatment. It was deemed important to offer a brief multidisciplinary fibromyalgia treatment program that provided fundamental education and established a foundation for self-management strategies. This article describes the components of a brief multidisciplinary program for fibromyalgia. Initial results indicate improvement in patient outcomes and in patient and physician satisfaction. Patients who complete any fibromyalgia program need to maintain a relationship with their primary care providers for ongoing care. Some patients may need a more comprehensive program because of their level of functional impairment. 177 PMID- 16261517 AU - Lukaczer D, Darland G, Tripp M, Liska D, Lerman RH, Schiltz B, Bland JS TI - A pilot trial evaluating Meta050, a proprietary combination of reduced iso-alpha acids, rosemary extract & oleanolic acid in pts w arthritis & FM.

DanLukaczer@metagenics.com AB - The aim of this open-label, 8-week observational trial was to investigate the efficacy of Meta050 (a proprietary, standardized combination of reduced iso-alpha-acids from hops, rosemary extract and oleanolic acid) on pain in patients with rheumatic disease. Osteoarthritis, rheumatoid arthritis and fibromyalgia patients were given 440 mg Meta050 three times a day for 4 weeks, which was changed to 880 mg twice a day for the subsequent 4 weeks in the majority of patients. Pain and condition-specific symptoms were assessed using a standard visual analog scale (VAS), an abridged arthritis impact measurement scale (AIMS2) and the fibromyalgia impact questionnaire. Fifty-four subjects with rheumatic disease completed the trial. Following treatment, a statistically significant decrease in pain of 50% and 40% was observed in arthritis subjects using the VAS (p < 0.0001; Wilcoxon-ranked sums) and AIMS2 (p < 0.0001), respectively. Fibromyalgia subject scores did not significantly improve. A decreasing trend of C-reactive protein, a marker for inflammation, was also observed in those subjects who presented with elevated C-reactive protein. No serious side effects were observed. These observations suggest that Meta050 at a dosage of 440 mg three times a day has a beneficial effect on pain in arthritis subjects. 178 PMID- 16174480 AU - Macfarlane GJ TI - Chronic widespread pain & FM: Should reports of increased mortality influence management?

Among the studies conducted there is little consistency in results. If there is an increased mortality risk, it is of the order of a 30% excess and it may be related to the lifestyle of patients with these symptoms, including lack of exercise. Skilled judgment is required in determining whether reports of new symptoms are likely to indicate underlying new pathology. Studies are currently underway which will determine whether initial observations of an increased mortality risk can be replicated. 179 PMID- 16264414 AU - Maes M, Mihaylova I, De Ruyter M TI - Decreased dehydroepiandrosterone sulfate but normal insulin-like growth factor in CFS (CFS): relevance for the inflammatory response in CFS.

AB - There are a few reports that chronic fatigue syndrome (CFS) may be accompanied by changes in hormones, such as dehydroepiandrosterone (DHEA) and insulin-like growth factor (IGF1). This study examines the serum concentrations of DHEA-sulfate (DHEAS), IGF1 and IGF1 binding protein-3 (IGFBP3) in 20 patients with CFS and in 12 normal controls. The IGFBP3/IGF1 ratio was computed as an index for IGF1 availability. We found significantly lower serum DHEAS concentrations in CFS, but no significant differences either in IGF1 or the IGFBP3/IGF1 ratio between CFS patients and normal controls. The decrease in serum DHEAS was highly sensitive and specific for CFS. There were significant and positive correlations between serum DHEAS and serum zinc and the mitogen-induced expression of the CD69 molecule on CD3+CD8+ T cells (an indicator of early T cell activation). There was a significant and negative correlation between serum DHEAS and the increase in the serum alpha-2 protein fraction (an inflammatory marker). Serum IGF1, but not DHEAS, was significantly and inversely correlated to age. The results show that CFS is accompanied by lowered levels of DHEAS and that the latter may play a role in the immune (defect in the early activation of T cells) and the inflammatory pathophysiology of CFS. 180 PMID- 16297163 AU - Maher KJ, Klimas NG, Fletcher MA TI - CFS is associated w diminished intracellular perforin. SO - Clin Exp Immunol. 2005 Dec;142(3):505-11. IN - D o Med, U o Miami Miller School o Medicine, Miami, FL 33176, USA. AB - Chronic fatigue syndrome (CFS) is an illness characterized by unexplained and prolonged fatigue that is often accompanied by abnormalities of immune, endocrine and cognitive functions. Diminished natural killer cell cytotoxicity (NKCC) is a frequently reported finding. However, the molecular basis of this defect of in vitro cytotoxicy has not been described. Perforin is a protein found within intracellular granules of NK and cytotoxic T cells and is a key factor in the lytic processes mediated by these cells. Quantitative fluorescence flow cytometry was used to the intracellular perforin content in CFS subjects and healthy controls. A significant reduction in the NK cell associated perforin levels in samples from CFS patients, compared to healthy controls, was observed. There was also an indication of a reduced perforin level within the cytotoxic T cells of CFS subjects, providing the first evidence, to our knowledge, to suggest a T cell associated cytotoxic deficit in CFS. Because perforin is important in immune surveillance and homeostasis of the immune system, its deficiency may prove to be an important factor in the pathogenesis of CFS and its analysis may prove useful as a biomarker in the study of CFS. 181 PMID- 15712623 AU - Maizels M, McCarberg B TI - Antidepressants & antiepileptic drugs for chr non-cancer pain.

IN - D o Family Practice, Kaiser Permanente, Woodland Hills, California 91365, USA. morris.maizels@kp.org AB - The development of newer classes of antidepressants and second-generation antiepileptic drugs has created unprecedented opportunities for the treatment of chronic pain. These drugs modulate pain transmission by interacting with specific neurotransmitters and ion channels. The actions of antidepressants and antiepileptic drugs differ in neuropathic and non-neuropathic pain, and agents within each medication class have varying degrees of efficacy. Tricyclic antidepressants (e.g., amitriptyline, nortriptyline, desipramine) and certain novel antidepressants (i.e., bupropion, venlafaxine, duloxetine) are effective in the treatment of neuropathic pain. The analgesic effect of these drugs is independent of their antidepressant effect and appears strongest in agents with mixed-receptor or predominantly noradrenergic activity, rather than serotoninergic activity. First-generation antiepileptic drugs (i.e., carbamazepine, phenytoin) and second-generation antiepileptic drugs (e.g., gabapentin, pregabalin) are effective in the treatment of neuropathic pain. The efficacy of antidepressants and antiepileptic drugs in the treatment of neuropathic pain is comparable; tolerability also is comparable, but safety and side effect profiles differ. Tricyclic antidepressants are the most cost-effective agents, but second-generation antiepileptic drugs are associated with fewer safety concerns in elderly patients. Tricyclic antidepressants have documented (although limited) efficacy in the treatment of fibromyalgia and chronic low back pain. Recent evidence suggests that duloxetine and pregabalin have modest efficacy in patients with fibromyalgia. 182 PMID- 15711234 AU - Mannerkorpi K TI - Exercise in FM.

IN - D o Rheumatology & Inflammation Research, Sahlgrenska Academy, Goteborg U, Goteborg, Sweden. kaisa.mannerkorpi@rheuma.gu.se AB - PURPOSE OF REVIEW: Several studies have indicated that physical exercise is beneficial for patients with fibromyalgia. The aim of this article is to review the recent literature relating to exercise in fibromyalgia, specifically articles published between September 2003 and September 2004, to highlight developments in the field. RECENT FINDINGS: Previous studies indicate that aerobic exercise performed at adequate intensity for an individual can improve function, symptoms, and well-being. A recent study of aerobic exercise showed that training in sedentary women with fibromyalgia using short bouts of exercise produces improvements in health outcomes. A study of aerobic walking resulted in improvements in physical function, symptoms, and distress. Two studies of low-intensity pool exercise reported a positive impact on fibromyalgia symptoms and distress. Two studies of qigong movement therapy were reported, one indicating improvements in symptoms and the other in movement harmony, indicating that this mode of exercise needs to be evaluated further. SUMMARY: The recent studies support existing literature on the benefits of exercise for patients with fibromyalgia. The outcomes appear to be related to the program design and the characteristics of the populations studied. As the patients with fibromyalgia form a heterogeneous population, more research is required to identify the characteristics of patients who benefit from specific modes of exercise. Moreover, long-term planning is needed to motivate the patients to continue regular exercise. Informing patients about the benefits of exercise and adjusting the exercise intensity to individual limitations enhances adherence. The social support gained by exercising in groups also enhances adherence to exercise. 183 PMID- 16012062 AU - Mannerkorpi K, Hernelid C TI - Leisure Time Physical Activity Instrument & Physical Activity at Home & Work Instrument.

IN - D o Rheumatology & Inflammation Research, Sahlgrenska Academy, Goteborg U, Goteborg. AB - PURPOSE: A new instrument measuring leisure time physical activity (LTPAI) in populations predominately engaging in low intensity activities and a new instrument measuring the Physical Activity at Home and Work (PAHWI) were designed. METHODS: Patients with long-lasting pain and expert physiotherapists participated in the development of the two instruments. Test-retest reliability was evaluated for the LTPAI and the PAHWI. Construct validity was evaluated for the LTPAI by comparing it with an instrument measuring physical activities for older people, six-minute walk test and aerobic capacity. POPULATION: 37 women with FM, with the mean age of 46 years (SD 8.4) and mean symptom duration of 11 years (SD 5.9) were recruited to the study. RESULTS: The mean time that the study population spent in physical activities during leisure time was 5.2 hours (SD 4.0) a week. Satisfactory test-retest reliability was found for the total score of LTPAI (ICC 0.86, CI 0.79 - 0.93) and for the PAHWI (ICC 0.91, CI 0.82 - 9.96). A significant association between the LTPAI and the six-minute walk test (rs 0.40, p = 0.02) and another physical activity instrument (rs 0.39, p = 0.02) was found. As expected, LTPAI did not have any association with aerobic capacity. CONCLUSIONS: Face validity of the instruments was ensured during the development process. Satisfactory test-retest reliability was found for the LTPAI and the PAHWI. Significant but low associations were found between the LTPAI and the six-minute walk test and an instrument designed for older people, respectively, while no association was found between the LTPAI and aerobic capacity. 184 PMID- 15902517 AU - Marcus DA, Bernstein C, Rudy TE TI - FM & headache: an epidemiological study supporting migraine as part of the FM syndrome. SO - Clin Rheumatol. 2005 Nov;24(6):595-601. Epub 2005 May 18. IN - D o Anesthesiology, U o Pittsburgh Med Ctr, PA, USA. AB - Fibromyalgia is defined by widespread body pain, tenderness to palpation of tender point areas, and constitutional symptoms. The literature reports headache in about half of fibromyalgia patients. The current epidemiological study was designed to determine the prevalence and characteristics of headache in fibromyalgia patients. Treatment-seeking fibromyalgia patients were evaluated with measures for fibromyalgia, chronic headache, quality of life, and psychological distress. Multivariate analysis of variance (MANOVA) and t-tests were used to identify significant differences, as appropriate. A total of 100 fibromyalgia patients were screened (24 fibromyalgia without headache and 76 fibromyalgia with headache). International Headache Society diagnoses included: migraine alone (n = 15 with aura, n = 17 without aura), tension-type alone (n = 18), combined migraine and tension-type (n = 16), post-traumatic (n = 4), and probable analgesic overuse headache (n = 6). Fibromyalgia tender point scores and counts and most measures of pain severity, sleep disruption, or psychological distress were not significantly different between fibromyalgia patients with and without headache. As expected, the fibromyalgia patients with headache scored higher on the Headache Impact Test (HIT-6) (62.1 +/- 0.9 vs 48.3 +/- 1.6, p < 0.001). HIT-6 scores were >60 in 80% of fibromyalgia plus headache patients, representing severe impact from headache, and 56-58 in 4%, representing substantial impact. In summary, chronic headache was endorsed by 76% of treatment-seeking fibromyalgia patients, with 84% reporting substantial or severe impact from their headaches. Migraine was diagnosed in 63% of fibromyalgia plus headache patients, with probable analgesic overuse headache in only 8%. General measures of pain, pain-related disability, sleep quality, and psychological distress were similar in fibromyalgia patients with and without headache. Therefore, fibromyalgia patients with headache do not appear to represent a significantly different subgroup compared to fibromyalgia patients without headache. The high prevalence and significant impact associated with chronic headache in fibromyalgia patients, however, warrants inclusion of a headache assessment as part of the routine evaluation of fibromyalgia patients. 185 PMID- 15616761 AU - Marques AP, Ferreira EA, Matsutani LA, Pereira CA, Assumpcao A TI - Quantifying pain threshold & quality of life of FM pts.

IN - D o Physical, Speech, & Occupational Therapy, School o Med, U o Sao Paulo, Rua Cipotania 51, Cidade Universitaria, Sao Paulo, 05360-160, Brazil, pasqual@usp.br AB - The most typical symptom of fibromyalgia (FM) is diffuse pain, and pain at specific points-tender points-is crucial for its diagnosis. By comparing healthy individuals and FM patients, this study was aimed at assessing pain and quality of life of Brazilian females with FM, while seeking for a correlation between pain threshold and quality of life. A total of 178 women were evaluated: 124 were FM patients and 54 were healthy women. Pain threshold at tender points was quantified by dolorimetry, and diffuse pain by means of the visual analogue scale (VAS); the Fibromyalgia Impact Questionnaire (FIQ) was used to evaluate quality of life. Statistical treatment of the data allowed for proposing two indexes: a pain threshold index (PT) and a quality of life one (QOL). PT is the lowest value among all pain thresholds measured at the 18 tender points; QOL is the mean of responses to the FIQ and VAS. Both indexes were tested and showed significant differences between the test and control groups. By pairing pain threshold values of each tender point in the test and control groups, it was found that the most sensitive points matched between the two groups, that is, the most sensitive anatomic spots in a healthy individual are also likely to be the most sensitive points in a person with FM. This suggests that a stimulus that provokes slight discomfort to a healthy person may produce more pain in FM patients--which may bear implications for FM clinical treatment. In this sample of Brazilian women, FM patients had both lower pain threshold and worse quality of life than healthy women. 186 PMID- 15992574 AU - Masuda A, Kihara T, Fukudome T, Shinsato T, Minagoe S, Tei C TI - The effects of repeated thermal therapy for 2 pts w CFS.

METHODS: Two patients with CFS underwent treatment with prednisolone (PSL), with no satisfactory effect. They were subjected to thermal therapy that consisted of a far-infrared ray dry sauna at 60 degrees C and postsauna warming. The therapy was performed once a day, for a total of 35 sessions. After discharge, these subjects continued the therapy once or twice a week on an outpatient basis for 1 year. RESULTS: Symptoms such as fatigue, pain, sleep disturbance, and low-grade fever were dramatically improved after 15 to 25 sessions of thermal therapy. Although PSL administration was discontinued, the subjects showed no relapse or exacerbation of symptoms during the first year after discharge. The patients became socially rehabilitated 6 months after discharge. CONCLUSIONS: These results suggest that repeated thermal therapy might be a promising method for the treatment of CFS. 187 PMID- 16207340 AU - McBeth J, Chiu YH, Silman AJ, Ray D, Morriss R, Dickens C, Gupta A, Macfarlane GJ TI - Hypothalamic-pituitary-adrenal stress axis function & the relationship w chr widespread pain & its antecedents. [FM] SO - Arthritis Res Ther. 2005;7(5):R992-R1000. Epub 2005 Jun 17. IN - Arthritis Research Campaign (ARC) Epidemiology Unit, School o Epidemiology & Health Sciences, U o Manchester, Manchester, United Kingdom. john.mcbeth@manchester.ac.uk AB - In clinic studies, altered hypothalamic-pituitary-adrenal (HPA) axis function has been associated with fibromyalgia, a syndrome characterised by chronic widespread body pain. These results may be explained by the associated high rates of psychological distress and somatisation. We address the hypothesis that the latter, rather than the pain, might explain the HPA results. A population study ascertained pain and psychological status in subjects aged 25 to 65 years. Random samples were selected from the following three groups: satisfying criteria for chronic widespread pain; free of chronic widespread pain but with strong evidence of somatisation ('at risk'); and a reference group. HPA axis function was assessed from measuring early morning and evening salivary cortisol levels, and serum cortisol after physical (pain pressure threshold exam) and chemical (overnight 0.25 mg dexamethasone suppression test) stressors. The relationship between HPA function with pain and the various psychosocial scales assessed was modelled using appropriate regression analyses, adjusted for age and gender. In all 131 persons with chronic widespread pain (participation rate 74%), 267 'at risk' (58%) and 56 controls (70%) were studied. Those in the chronic widespread pain and 'at risk' groups were, respectively, 3.1 (95% CI (1.3, 7.3)) and 1.8 (0.8, 4.0) times more likely to have a saliva cortisol score in the lowest third. None of the psychosocial factors measured were, however, associated with saliva cortisol scores. Further, those in the chronic widespread pain (1.9 (0.8, 4.7)) and 'at risk' (1.6 (0.7, 3.6)) groups were also more likely to have the highest serum cortisol scores. High post-stress serum cortisol was related to high levels of psychological distress (p = 0.05, 95% CI (0.02, 0.08)). After adjusting for levels of psychological distress, the association between chronic widespread pain and post-stress cortisol scores remained, albeit slightly attenuated. This is the first population study to demonstrate that those with established, and those psychologically at risk of, chronic widespread pain demonstrate abnormalities of HPA axis function, which are more marked in the former group. Although some aspects of the altered function are related to the psychosocial factors measured, we conclude that the occurrence of HPA abnormality in persons with chronic widespread pain is not fully explained by the accompanying psychological stress. 188 PMID- 16268331 AU - McCabe C, Lewis J, Shenker N, Hall J, Cohen H, Blake D TI - Don't look now! Pain & attention. [FM] SO - Clin Med. 2005 Sep-Oct;5(5):482-6. IN - Royal Nat Hosp for Rheumatic Diseases, Bath. candy.mccabe@rnhrd-tr.swest.nhs.uk AB - Attention and pain are linked inexorably. The manipulation of attention, via either distraction or focused attention, has been used as a therapeutic initiative for generations. Imaging evidence and clinical observations demonstrate that attention can be altered with associated changes at the cortical level and this may have positive or negative effects on the individual. New theories suggest that cortical remapping and visual attention may play key roles in a cortical model of pain specifically involving the motor control system. Within this system, the relationship between allocentric (external) and egocentric (internal) stimuli are managed; where conflict occurs, somaesthetic disturbances may be generated. If an individual pays too much attention to such sensory disturbances, then they may report the disturbances as abnormal symptoms, which may explain the diverse symptomatology of fibromyalgia. The use of a therapeutic optokinetic device to correct existing imbalances in the motor control system is also discussed. 189 PMID- 15750469 AU - McGhee SA, Kaska B, Liebhaber M, Stiehm ER TI - Persistent parvovirus-associated chr fatigue treated w high dose intravenous immunoglobulin.

A large body of data indicates a neurobiological basis for these disorders, but this information has not been effectively transmitted to many medical professionals. METHODS: Contemporary data on the epidemiologic characteristics of FM and CWP are reviewed, and evidence for a neurobiological basis for these disorders is presented. In addition, possible predisposing, triggering, and maintaining factors for the development of these disorders are discussed. RESULTS: Approximately 10% of the population have CWP, and approximately 4% have FM. The tender point criteria for FM have resulted in the common misconception among health care professionals that this spectrum of disorders is limited to women with high degrees of psychological distress. A hallmark of FM is the presence of non-nociceptive, central pain. There is evidence of centrally augmented pain processing, which can be detected both with sensory testing and by more objective measures (e.g., evoked potentials, functional neuroimaging). DISCUSSION: An appreciation of the neurobiological basis for these disorders, and an understanding of some of the abnormalities of pain processing present in patients with FM, will hopefully provide greater understanding of these patients. It may also serve to decrease the level of frustration and improve the care experience of both chronic pain patients and physicians. 191 PMID- 16019393 AU - McLean SA, Williams DA, Clauw DJ TI - FM after motor vehicle collision: evidence & implications.

IN - D o Emergency Med & The Chronic Pain & Fatigue Research Ctr, U o Michigan Med Center, Ann Arbor, Michigan, USA. samclean@umich.edu AB - OBJECTIVE: Assess currently available evidence regarding the ability of a motor vehicle collision (MVC) to trigger the development of fibromyalgia (FM). METHODS: Consensus standards developed by the American College of Rheumatology Environmental Disease Study Group were used to assess the ability of an MVC to trigger FM. RESULTS: Increasing evidence suggests that FM and related disorders are characterized by abnormalities in central nervous system function related to sensory processing, autonomic regulation, and neuroendocrine function. MVC trauma appears capable of triggering FM, but generally not through direct biomechanical injury. Instead, the evidence suggests that MVC trauma can act as a "stressor," which in concert with other factors, such as an individual's biologic vulnerability, psychosocial factors, cultural factors, and so on, may result in the development of chronic widespread pain and other somatic symptoms. MVC trauma is only one of many stressors which can trigger such disorders, and the environment within which the stressor is experienced (biological and psychosocial) may largely determine whether there is an adverse physiologic result or not. CONCLUSIONS: The evidence that MVC trauma may trigger FM meets established criteria for determining causality, and has a number of important implications, both for patient care, and for research into the pathophysiology and treatment of these disorders. 192 PMID- 16258904 AU - McLean SA, Williams DA, Harris RE, Kop WJ, Groner KH, Ambrose K, Lyden AK, Gracely RH, Crofford LJ, Geisser ME, Sen A, Biswas P, Clauw DJ TI - Momentary relationship between cortisol secretion & Sx in pts w FM.

IN - Chronic Pain & Fatigue Research Ctr, U o Michigan Med Center, 24 Frank Lloyd Wright Drive, PO Box 385, Ann Arbor, MI 48106, USA. samclean@umich.edu AB - OBJECTIVE: To compare the momentary association between salivary cortisol levels and pain, fatigue, and stress symptoms in patients with fibromyalgia (FM), and to compare diurnal cycles of cortisol secretion in patients with FM and healthy control subjects in a naturalistic environment. METHODS: Twenty-eight patients with FM and 27 healthy control subjects completed assessments on salivary cortisol levels and pain, fatigue, and stress symptoms, 5 times a day for 2 consecutive days, while engaging in usual daily activities. Only those participants who adhered to the protocol (assessed via activity monitor) were included in the final analyses. RESULTS: Twenty FM patients and 16 healthy control subjects adhered to the protocol. There were no significant differences in cortisol levels or diurnal cortisol variation between FM patients and healthy controls. Among women with FM, a strong relationship between cortisol level and current pain symptoms was observed at the waking time point (t = 3.35, P = 0.008) and 1 hour after waking (t = 2.97, P = 0.011), but not at the later 3 time points. This association was not due to differences in age, number of symptoms of depression, or self-reported history of physical or sexual abuse. Cortisol levels alone explained 38% and 14% of the variation in pain at the waking and 1 hour time points, respectively. No relationship was observed between cortisol level and fatigue or stress symptoms at any of the 5 time points. CONCLUSION: Among women with FM, pain symptoms early in the day are associated with variations in function of the hypothalamic-pituitary-adrenal axis. 193 PMID- 16259313 AU - Mears T TI - Acupuncture in the Rx of post viral fatigue syndrome--a case report.

IN - Swedish Med Ctr, the U o Washington School o Med, Seattle, WA, USA. pmease@nwlink.com AB - The objectives of the first OMERACT Fibromyalgia Syndrome (FM) Workshop were to identify and prioritize symptom domains that should be consistently evaluated in FM clinical trials, and to identify aspects of domains and outcome measures that should be part of a concerted research agenda of FM researchers. Such an effort will help standardize and improve the quality of outcomes research in FM. A principal assumption in this workshop has been that there exists a clinical syndrome, generally known as FM, characterized by chronic widespread pain typically associated with fatigue, sleep disturbance, mood disturbance, and other symptoms and signs, and considered to be related to central neuromodulatory dysregulation. FM can be diagnosed using 1990 American College of Rheumatology criteria. In preparation for the workshop a Delphi exercise involving 23 FM researchers was conducted to establish a preliminary prioritization of domains of inquiry. At the OMERACT meeting, the workshop included presentation of the Delphi results; a review of placebo-controlled trials of FM treatment, with a focus on the outcome measures used and their performance; a panel discussion of the key issues in FM trials, from both an investigator and regulatory agency perspective; and a voting process by the workshop attendees. The results of the workshop were presented in the plenary session on the final day of the meeting. A prioritized list of domains of FM to be investigated was thus developed, key issues and controversies in the field were debated, and consensus on a research agenda on outcome measure development was reached. 195 PMID- 16078356 AU - Mease P TI - FM syndrome: review of clinical presentation, pathogenesis, outcome measures, & Rx. SO - J Rheumatol Suppl. 2005 Aug;75:6-21. IN - Seattle Rheumatology Associates, Washington 98104, USA. pmease@nwlink.com AB - Fibromyalgia syndrome (FM) is a common chronic pain condition that affects at least 2% of the adult population in the USA and other regions in the world where FM is studied. Prevalence rates in some regions have not been ascertained and may be influenced by differences in cultural norms regarding the definition and attribution of chronic pain states. Chronic, widespread pain is the defining feature of FM, but patients may also exhibit a range of other symptoms, including sleep disturbance, fatigue, irritable bowel syndrome, headache, and mood disorders. Although the etiology of FM is not completely understood, the syndrome is thought to arise from influencing factors such as stress, medical illness, and a variety of pain conditions in some, but not all patients, in conjunction with a variety of neurotransmitter and neuroendocrine disturbances. These include reduced levels of biogenic amines, increased concentrations of excitatory neurotransmitters, including substance P, and dysregulation of the hypothalamic-pituitary-adrenal axis. A unifying hypothesis is that FM results from sensitization of the central nervous system. Establishing diagnosis and evaluating effects of therapy in patients with FM may be difficult because of the multifaceted nature of the syndrome and overlap with other chronically painful conditions. Diagnostic criteria, originally developed for research purposes, have aided our understanding of this patient population in both research and clinical settings, but need further refinement as our knowledge about chronic widespread pain evolves. Outcome measures, borrowed from clinical research in pain, rheumatology, neurology, and psychiatry, are able to distinguish treatment response in specific symptom domains. Further work is necessary to validate these measures in FM. In addition, work is under way to develop composite response criteria, intended to address the multidimensional nature of this syndrome. A range of medical treatments, including antidepressants, opioids, nonsteroidal antiinflammatory drugs, sedatives, muscle relaxants, and antiepileptics, have been used to treat FM. Nonpharmaceutical treatment modalities, including exercise, physical therapy, massage, acupuncture, and cognitive behavioral therapy, can be helpful. Few of these approaches have been demonstrated to have clear-cut benefits in randomized controlled trials. However, there is now increased interest as more effective treatments are developed and our ability to accurately measure effect of treatment has improved. The multifaceted nature of FM suggests that multimodal individualized treatment programs may be necessary to achieve optimal outcomes in patients with this syndrome. 196 PMID- 16100965 AU - Mercante JP, Peres MF, Guendler V, Zukerman E, Bernik MA TI - Depression in chr migraine: severity & clinical features.

IN - Psicologa, pesquisadora do Instituto de Ensino e Pesquisa do Hosp Israelita Albert Einstein, Sao Paulo SP, Brasil. julianeperes@terra.com.br AB - INTRODUCTION: Chronic migraine (CM) is a common medical condition affecting 2.4% of the general population. Depression is one of the most frequent comorbid disorders in CM. METHOD: Seventy patients diagnosed with chronic migraine were studied. All patients evaluated filled out the Beck Depression Inventory (BDI). Depression severity was divided into none or minimal depression, mild, moderate, and severe. RESULTS: BDI ranged from 4 to 55, mean 21 +/- 10.7. Moderate or severe depression, were present in 58.7% of the patients. Some degree of depression appeared in 85.8% of patients. The BDI scores correlated with pain intensity (p = 0.02). Severe depression was more frequent in patients with comorbid fibromyalgia and in patients reporting fatigue. CONCLUSION: The BDI is an easy tool to access depression in CM patients. Suicide risk assessment is needed in CM patients. Patients with fibromyalgia and fatigue are at even higher risk for severe depression. 197 PMID- 16372904 AU - Michalsen A, Riegert M, Ludtke R, Backer M, Langhorst J, Schwickert M, Dobos GJ TI - Mediterranean diet or extended fasting's influence on changing the intestinal microflora, immunoglobulin A secretion & clinical outcome in pts w RA & FM: an observational study.

IN - Kliniken Essen-Mitte, D o Internal & Integrative Med, U Duisburg-Essen, am Deimelsberg 34a, 45276 Essen, Germany. andreas.michalsen@uni-essen.de AB - BACKGROUND: Alterations in the intestinal bacterial flora are believed to be contributing factors to many chronic inflammatory and degenerative diseases including rheumatic diseases. While microbiological fecal culture analysis is now increasingly used, little is known about the relationship of changes in intestinal flora, dietary patterns and clinical outcome in specific diseases. To clarify the role of microbiological culture analysis we aimed to evaluate whether in patients with rheumatoid arthritis (RA) or fibromyalgia (FM) a Mediterranean diet or an 8-day fasting period are associated with changes in fecal flora and whether changes in fecal flora are associated with clinical outcome. METHODS: During a two-months-period 51 consecutive patients from an Integrative Medicine hospital department with an established diagnosis of RA (n = 16) or FM (n = 35) were included in the study. According to predefined clinical criteria and the subjects' choice the patients received a mostly vegetarian Mediterranean diet (n = 21; mean age 50.9 +/-13.3 y) or participated in an intermittent modified 8-day fasting therapy (n = 30; mean age 53.7 +/- 9.4 y). Quantitative aerob and anaerob bacterial flora, stool pH and concentrations of secretory immunoglobulin A (sIgA) were analysed from stool samples at the beginning, at the end of the 2-week hospital stay and at a 3-months follow-up. Clinical outcome was assessed with the DAS 28 for RA patients and with a disease severity rating scale in FM patients. RESULTS: We found no significant changes in the fecal bacterial counts following the two dietary interventions within and between groups, nor were significant differences found in the analysis of sIgA and stool ph. Clinical improvement at the end of the hospital stay tended to be greater in fasting vs. non-fasting patients with RA (p = 0.09). Clinical outcome was not related to alterations in the intestinal flora. CONCLUSION: Neither Mediterranean diet nor fasting treatments affect the microbiologically assessed intestinal flora and sIgA levels in patients with RA and FM. The impact of dietary interventions on the human intestinal flora and the role of the fecal flora in rheumatic diseases have to be clarified with newer molecular analysis techniques. The potential benefit of fasting treatment in RA and FM should be further tested in randomised trials. 198 PMID- 16372029 AU - Mihrshahi R, Beirman R TI - Aetiology & pathogenesis of CFS: a review.

This paper reviews the scientific literature related to current theories about the aetiology and pathogenesis of CFS by focussing on what appear to be the four most significant aspects in the development and perpetuation of this disease: the role of infectious agents as well as immunological, neuroendocrine, and psychiatric factors. A multifactorial model for the aetiology of CFS, which includes and draws together these four aspects, is proposed; and suggestions are offered regarding approaches to the diagnosis and treatment of this disease. 199 PMID- 16314601 AU - Montoya P, Sitges C, Garcia-Herrera M, Izquierdo R, Truyols M, Blay N, Collado D TI - Abnormal affective modulation of somatosensory brain processing among pts w FM.

Nevertheless, very little is known about the effects of negative mood induction on brain processing of somatosensory information in fibromyalgia. The objective of the present study was to examine the influence of two emotional states (pleasant and unpleasant) on brain activity of patients with fibromyalgia (FM; n = 27) and with musculoskeletal (MSK) pain resulting from identifiable somatic lesions (n = 16). METHODS: For this purpose, somatosensory-evoked potentials (SEPs) elicited by nonpainful pneumatic stimuli, delivered to the right and left hand following an oddball paradigm, were recorded when patients were viewing affective slides. RESULTS: As compared with patients with MSK pain, patients with FM displayed overall larger P50 amplitude to tactile stimuli. In addition, significantly larger P50 and smaller N80 amplitudes were found within patients with FM when they were viewing the unpleasant rather than the pleasant slides. CONCLUSION: Our data suggest an abnormal processing of nonpainful somatosensory information in FM, especially when somatic signals are arising from the body within an aversive stimulus context. These findings provide further support for the use of biopsychosocial models for understanding FM and other chronic pain states. 200 PMID- 15862479 AU - Montoya P, Pauli P, Batra A, Wiedemann G TI - Altered processing of pain-related information in pts w FM.

IN - D o Psychology & Research Inst on Health Sciences, U o the Balearic Islands, Palma, Spain. pedro.montoya@uib.es AB - Pressure pain thresholds (PPTs) and event-related potentials (ERPs) elicited by emotional words were analyzed in 12 patients with fibromyalgia (FM) and 12 matched healthy subjects. PPTs were assessed at the middle finger of both hands, before and after the experiment. Overall, FM patients and healthy subjects did not differ in PPT. Nevertheless, FM patients as compared with healthy controls were characterized by a significant enhancement of pain sensitivity from the beginning to the end of the experiment indicating a long lasting sensitization due to repeated stimulation. ERPs were recorded during a language decision task where subjects had to react to unpleasant pain-related and emotionally neutral words depending on syntactic or orthographic cues. An emotional category effect was observed on N400 and P300 components of the ERP, indicating that unpleasant words elicited more positive amplitudes than neutral words. A significant group effect was observed on P200 amplitudes, showing reduced amplitudes in FM patients as compared to healthy controls. Furthermore, unpleasant pain-related compared to neutral words triggered significantly enhanced late positive slow waves in healthy controls, while a comparable effect was not found in FM patients. The ERP and PPT data suggest that FM patients are characterized by an altered cognitive processing of pain-related information and by an abnormal adaptation to mechanical pain stimuli, respectively. 201 PMID- 15743467 AU - Morf S, Amann-Vesti B, Forster A, Franzeck UK, Koppensteiner R, Uebelhart D, Sprott H TI - Microcirculation abnormalities in pts w FM - measured by capillary microscopy & laser fluxmetry.

All 40 subjects were tested within a 5-week period by the same investigators, using two noninvasive methods, laser fluxmetry and capillary microscopy. The FM patients were compared with the healthy controls (negative controls) and with rheumatoid arthritis patients and SSc patients (positive controls). FM patients had fewer capillaries in the nail fold (P < 0.001) and significantly more capillary dilatations (P < 0.05) and irregular formations (P < 0.01) than the healthy controls. Interestingly, the peripheral blood flow in FM patients was much less (P < 0.001) than in healthy controls but did not differ from that of SSc patients (P = 0.73). The data suggest that functional disturbances of microcirculation are present in FM patients and that morphological abnormalities may also influence their microcirculation. 202 PMID- 15759948 AU - Morris CR, Bowen L, Morris AJ TI - Integrative therapy for FM: possible strategies for an individualized Rx program.

While physicians focus primarily on pharmacologic treatment, a number of nonpharmacologic modalities have been shown to benefit patients as well. No one therapy is uniformly effective in every patient; treatment programs consisting of a combination of pharmacologic and nonpharmacologic therapies must be individualized to the patient, and the clinician may have to try several different modalities before reaching an optimal improvement in the patient's symptoms. 203 PMID- 15684437 AU - Moss J TI - Development of a functional ability scale for children & young people w myalgic encephalopathy (ME)/CFS (CFS).

A new scale was developed from the Moss Ability Scale using the critique of 251 children and young people from the Association of Young People with ME (AYME). Responding to the shift in emphasis towards patients taking an active role in their own care, it was felt these young people would know whether the scale measured what it had set out to measure, and were asked questions on the face and content validity of the scale. There was a 99 percent agreement between the young people that the final scale was 'workable' or better. 204 PMID- 15723894 AU - Moss-Morris R, Sharon C, Tobin R, Baldi JC TI - A randomized controlled graded exercise trial for CFS: outcomes & mechanisms of change.

Forty-nine CFS patients were randomized to a 12-week graded exercise programme or to standard medical care. At the end of treatment the exercise group rated themselves as significantly more improved and less fatigued than the control group. A decrease in symptom focusing rather than an increase in fitness mediated the treatment effect. Graded exercise appears to be an effective treatment for CFS and it operates in part by reducing the degree to which patients focus on their symptoms. 205 PMID- 15940777 AU - Narvaez J, Nolla JM, Valverde-Garcia J TI - Lack of association of FM w hepatitis C virus infection.

IN - D o Rheumatology, Hosp Universitario de Bellvitge-IDIBELL, Barcelona, Spain. 31577edd@comb.es AB - OBJECTIVE: An association between chronic hepatitis C virus (HCV) infection and fibromyalgia (FM) remains controversial, mainly because previous studies were based on prevalent case series or comparisons with less than optimal control groups. We investigated whether there might be an association between chronic HCV infection and FM. METHODS: We prospectively investigated the prevalence of HCV infection in a series of 115 patients with FM and compared it with the prevalence in the general population of our community reported in the same period. Anti-HCV antibodies were determined by ELISA. In positive cases, infection was confirmed by recombinant immunoblot assay and HCV-RNA was detected by PCR using sera samples. Differences between prevalence rates were assessed by chi-square test. RESULTS: HCV infection was confirmed in 3 of 115 patients with FM (2.6%). Two of these patients (1.74%) had active HCV infection shown by the presence of viral RNA in serum, whereas HCV RNA was undetectable in the third patient. In these cases, liver disease had previously been undiagnosed and HCV infection manifested itself by extrahepatic symptoms. Although the prevalence of HCV infection was slightly higher in patients with FM than in the general population in the age groups 25-44 and 45-64 years, when we compared prevalence rates in the total group and the different age groups, no statistically significant differences were found. CONCLUSION: From our results, it seems unlikely that HCV infection plays a pathogenic role in FM. 206 PMID- 15693096 AU - Naschitz JE, Rozenbaum M, Fields MC, Enis S, Manor H, Dreyfuss D, Peck S, Peck ER, Babich JP, Mintz EP, Sabo E, Slobodin G, Rosner I TI - Cardiovascular reactivity in FM: evidence for pathogenic heterogeneity.

Naschitz@tx.technion.ac.il AB - OBJECTIVE: To evaluate disease-specific cardiovascular reactivity patterns in patients with fibromyalgia (FM) using a recently described method called fractal and recurrence analysis score (FRAS). METHODS: The study group included 30 women with FM, average age 46.7 years (SD 7.03). An age matched group of 30 women with other rheumatic disorders or having a dysautonomic background [chronic fatigue syndrome (CFS), non-CFS fatigue, neurally mediated syncope, and psoriatic arthritis (PsA)] served as controls. Subjects were evaluated with a head-up tilt test with beat-to-beat recording of the heart rate (HR) and pulse transit time. A 10-minute supine phase was followed by 600 cardiac cycles recorded on tilt. Data were processed by recurrence plot and fractal analysis. Variables acting as independent predictors of the cardiovascular reactivity were identified in FM patients versus controls. RESULTS: No statistically significant differences were found between the groups by univariate analysis comparing 92 variables of cardiovascular reactivity in FM patients compared to controls. CONCLUSION: Study of cardiovascular reactivity utilizing a head-up tilt test and processing the data using the FRAS method did not reveal a specific FM-associated abnormality. Our data confirm studies that utilized other methodologies and reached similar conclusions. Patients with FM represent a heterogenous group with respect to their pattern of cardiovascular reactivity. 207 PMID- 15838538 AU - Naschitz JE, Mussafia-Priselac R, Peck ER, Peck S, Naftali N, Storch S, Slobodin G, Elias N, Rosner I TI - Hyperventilation & amplified blood pressure response: is there a link?

Naschitz@tx.technion.ac.il AB - Based on prior studies, the hypothesis that hyperventilation (HV) may have a pressor effect and play a causal role in hypertension has been suggested. The objective of this study was to correlate HV with blood pressure (BP)-change during a postural challenge. Consecutive subjects referred for evaluation of syncope, dizziness, chronic fatigue syndrome (CFS), fibromyalgia, or non-CFS fatigue were assessed with a 10-min supine 30-min head-up tilt test combined with capnography. We selected for analysis the records of patients aged 17-70 years, not taking vasoactive medications, having sitting systolic BP (SBP) < 140 mmHg, sitting diastolic BP (DBP) < 90 mmHg, and who completed 30 min of tilt. HV was diagnosed when end-tidal pressure of CO2 < 30 mmHg was recorded consecutively for > or = 10 min. Postural hypertension (PHT) was diagnosed when DBP on tilt > or = 90 mmHg was recorded consecutively for > or = 10 min. DBP-change was computed as (median DBP on tilt) -(median DBP supine). PHT and DBP-change were correlated with HV. A total of 320 patient charts were reviewed. PHT was present in 30 cases. The mean DBP-change in patients with PHT was +9.9 mmHg (s.d. 5.8), with three patients manifesting HV. Of the remaining 290 patients, 56 had HV, their mean DBP-change was -0.3 mmHg (s.d. 7.2). The other 234 patients without HV had a mean DBP-change +0.95 mmHg (s.d. 5.7), comparable to the DBP-change in patients with HV. In, conclusion, posturally induced HV was not associated with an increase in BP, nor was PHT associated with HV, except in a small minority of cases. 208 PMID- 15330754 AU - Naschitz JE, Rozenbaum M, Fields M, Isseroff H, Enis S, Babich JP, Peck S, Peck ER, Gaitini L, Naschitz S, Sabo E, Rosner I TI - Search for disease-specific cardiovascular reactivity patterns: developing the methodology.

Naschitz@tx.technion.ac.il AB - Aberrations of CVR (cardiovascular reactivity), an expression of autonomic function, lack specificity for a particular disorder. Recently, a CVR pattern particular to chronic fatigue syndrome has been observed. In the present study, we aimed to develop methodologies for assessing disease-specific CVR patterns. As a prototype, a population of 50 consecutive patients with FMF (familial Mediterranean fever) was studied and compared with control populations. A 10 min supine/30 min head-up tilt test with recording of the heart rate and blood pressure or the pulse transit time was performed. Five studies were conducted applying different methods. In each study, statistical analysis identified independent predictors of CVR in FMF. Based on regression coefficients of these predictors, a linear DS (discriminant score) was computed for every subject. Each study established an equation to assess CVR, calculate DS for FMF and determine the sensitivity and specificity of the DS cut-off. In each of the five studies, abnormal CVR was observed in FMF patients. The best accuracy (88% sensitivity and 90.1% specificity for FMF) was obtained by a method based on beat-to-beat heart rate and pulse transit time recordings. Data was processed by fractal and recurrence quantitative analysis with recordings in FMF patients compared with a mixed control population. Identification of disease-specific CVR patterns was possible with the methodologies described in the present study. In FMF, disease-specific CVR may be explained by the interplay between neuroendocrine loops specific to FMF with cardiovascular homoeostatic mechanisms. Recognition of disease-specific CVR patterns may advance the understanding of homoeostatic mechanisms and have implications in clinical practice. 209 PMID- 15642984 AU - Natelson BH, Weaver SA, Tseng CL, Ottenweller JE TI - Spinal fluid abnormalities in pts w CFS.

IN - CFS Cooperative Research Ctr & D o Neurosciences, U o Med & Dentistry o New Jersey-New Jersey MS, Newark, New Jersey, USA. bhn@njneuromed.org AB - Arguments exist as to the cause of chronic fatigue syndrome (CFS). Some think that it is an example of symptom amplification indicative of functional or psychogenic illness, while our group thinks that some CFS patients may have brain dysfunction. To further pursue our encephalopathy hypothesis, we did spinal taps on 31 women and 13 men fulfilling the 1994 case definition for CFS and on 8 women and 5 men serving as healthy controls. Our outcome measures were white blood cell count, protein concentration in spinal fluid, and cytokines detectable in spinal fluid. We found that significantly more CFS patients had elevations in either protein levels or number of cells than healthy controls (30 versus 0%), and 13 CFS patients had protein levels and cell numbers that were higher than laboratory norms; patients with abnormal fluid had a lower rate of having comorbid depression than those with normal fluid. In addition, of the 11 cytokines detectable in spinal fluid, (i) levels of granulocyte-macrophage colony-stimulating factor were lower in patients than controls, (ii) levels of interleukin-8 (IL-8) were higher in patients with sudden, influenza-like onset than in patients with gradual onset or in controls, and (iii) IL-10 levels were higher in the patients with abnormal spinal fluids than in those with normal fluid or controls. The results support two hypotheses: that some CFS patients have a neurological abnormality that may contribute to the clinical picture of the illness and that immune dysregulation within the central nervous system may be involved in this process. 210 PMID- 16260962 AU - Nijs J, Meeus M, McGregor NR, Meeusen R, de Schutter G, van Hoof E, de Meirleir K TI - CFS: exercise performance related to immune dysfunction. SO - Med Sci Sports Exerc. 2005 Oct;37(10):1647-54. IN - D o Human Physiology, Faculty o Physical Education & Physiotherapy, Vrije Universiteit Brussel, Brussels, Belgium. AB - PURPOSE: To date, the exact cause of abnormal exercise response in chronic fatigue syndrome (CFS) remains to be revealed, but evidence addressing intracellular immune deregulation in CFS is growing. Therefore, the aim of this cross-sectional study was to examine the interactions between several intracellular immune variables and exercise performance in CFS patients. METHODS: After venous blood sampling, subjects (16 CFS patients) performed a maximal exercise stress test on a bicycle ergometer with continuous monitoring of cardiorespiratory variables. The following immune variables were assessed: the ratio of 37 kDa Ribonuclease (RNase) L to the 83 kDa native RNase L (using a radiolabeled ligand/receptor assay), RNase L enzymatic activity (enzymatic assay), protein kinase R activity assay (comparison Western blot), elastase activity (enzymatic-colorimetric assay), the percent of monocytes, and nitric oxide determination (for monocytes and lymphocytes; flow cytometry, live cell assay). RESULTS: Forward stepwise multiple regression analysis revealed 1) that elastase activity was the only factor related to the reduction in oxygen uptake at a respiratory exchange ratio (RER) of 1.0 (regression model: R = 0.53, F (1,14) = 15.5, P < 0.002; elastase activity P < 0.002); 2) that the protein kinase R activity was the principle factor related to the reduction in workload at RER = 1.0; and 3) that elastase activity was the principle factor related to the reduction in percent of target heart rate achieved. CONCLUSION: These data provide evidence for an association between intracellular immune deregulation and exercise performance in patients with CFS. To establish a causal relationship, further study of these interactions using a prospective longitudinal design is required. 211 PMID- 16323389 AU - Nijs J, Van de Putte K, Louckx F, De Meirleir K TI - Employment status in CFS.

DESIGN: Cross-sectional observational study. SETTING: A university-based chronic fatigue clinic. SUBJECTS: Fifty-four consecutive, Flemish, employed (not self-employed) chronic fatigue syndrome patients (49/54 female). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants were questioned about their current and premorbid employment status, filled in the Chronic Fatigue Syndrome Activities and Participation Questionnaire (CFS-APQ), the Medical Outcomes Short Form 36 Health Status Survey (SF-36), and performed a maximal exercise test on a bicycle ergometer with continuous monitoring of cardiorespiratory variables. RESULTS: A significant association was observed between the current employment rate and two SF-36 subscales (i.e., role limitations due to physical functioning and social functioning; rho = 0.39 and 0.35 respectively) (n = 54). Analysing only the female chronic fatigue syndrome patients (n = 49), the current employment rate correlated significantly with the peak workload (rho = 0.38). CONCLUSIONS: The associations between either exercise testing or self-reported disability and employment status are too weak to predict employment status. 212 PMID- 16277015 AU - Nijs J, De Meirleir K TI - Impairments of the 2-5A synthetase/RNase L pathway in CFS.

Jo.Nijs@vub.ac.be AB - This paper provides an overview of the evidence addressing the impairments of the 2'-5' oligoadenylate (2-5 A) synthetase/RNase L pathway in Chronic Fatigue Syndrome (CFS) patients. The 2-5A synthetase/RNase L pathway in CFS patients appears to be both up-regulated (i.e. increased levels of bioactive 2-5A synthetase and increased activity of the RNase L enzyme) and deregulated (elastase and calpain initiate 83 kDa RNase L proteolysis, generating two major fragments with molecular masses of 37 and 30 kDa, respectively). The deregulation of the 2-5A synthetase/RNase L pathway in CFS accompanies decreased NK-function and deregulation of apoptotic pathways. Since various components of the pathway appear to be related to performance during a graded exercise stress test, some evidence supportive of the clinical importance of the impaired pathway in CFS patients has been provided. Studies addressing the treatment of the deregulation of the 2-5A synthetase/RNase L pathway in CFS are warranted. 213 PMID- 15617866 AU - Nijs J, Van de Velde B, De Meirleir K TI - Pain in pts w CFS: does nitric oxide trigger central sensitisation?

IN - D o Human Physiology, Faculty o Physical Education & Physical Therapy, Vrije Universiteit Brussel (VUB), Belgium. jo.nijs@vub.ac.be AB - Previous studies have provided evidence supportive of the clinical importance of widespread pain in patients with chronic fatigue syndrome (CFS): pain severity may account for 26-34% of the variability in the CFS patient's activity limitations and participation restrictions. The etiology of widespread pain in CFS remains to be elucidated, but sensitisation of the central nervous system has been suggested to take part of CFS pathophysiology. It is hypothesised that a nitric oxide (NO)-dependent reduction in inhibitory activity of the central nervous system and consequent central sensitisation accounts for chronic widespread pain in CFS patients. In CFS patients, deregulation of the 2',5'-oligoadenylate synthetase/RNase L pathway is accompanied by activation of the protein kinase R enzyme. Activation of the protein kinase R and subsequent nuclear factor-kappaB activation might account for the increased production of NO, while infectious agents frequently associated with CFS (Coxsackie B virus, Epstein-Barr Virus, Mycoplasma) might initiate or accelerate this process. In addition, the evidence addressing behavioural changes in CFS patients fits the central sensitisation-hypothesis: catastrophizing, avoidance behaviour, and somatization may result in, or are initiated by sensitisation of the central nervous system. 214 PMID- 16136868 AU - Nijs J, Vaes P, De Meirleir K TI - The CFS Activities & Participation Questionnaire (CFS-APQ): an overview.

Jo.Nijs@vub.ac.be AB - Chronic fatigue syndrome (CFS) is characterized by severe fatigue and a reduction in activity levels. The purpose of this study was to provide an overview of design, reliability, and validity of the CFS Activities and Participation Questionnaire (CFS-APQ). The CFS-APQ was constructed based on a retrospective analysis of the Karnofsky Performance Status Questionnaire and the Activities of Daily Living Questionnaire (n = 141). In a reliability study of 34 participants the test-retest reliability coefficient of the CFS-APQ was 0.95. In two different studies, the Cronbach alpha coefficient for internal consistency varied between 0.87 (n = 88) and 0.94 (n = 47). The CFS-APQ was administered to 47 patients who listed 183 activities that had become difficult due to their chronic symptoms, and 157 (85.8%) answers matched the content of the CFS-APQ. The outcome of a cross-sectional study (n = 88) studying the correlations between the Medical Outcomes Short Form 36 Health Status Survey subscale scores and the CFS-APQ supported the validity of the CFS-APQ. The CFS-APQ scores correlated with a behavioural assessment of the patients' performance of activities encompassed by the questionnaire (r = 0.29-0.55; n = 63), and correlated with exercise capacity parameters (r = 0.26-0.39; n = 77) obtained during a maximal exercise capacity stress test. Finally, the CFS-APQ correlated with visual analogue scales for pain (r = 0.51) and fatigue (r = 0.50; n = 47). It is concluded that the CFS-APQ generates reliable and valid data, and can be used as a clinical measure of disease severity in patients with CFS. Future studies should aim at examining the sensitivity of the CFS-APQ. 215 PMID- 16191727 AU - Njoku MG, Jason LA, Torres-Harding SR TI - The relationships among coping styles & fatigue in an ethnically diverse sample.

IN - Center for Community Research, Chronic Fatigue Research Study, Chicago, IL 60614, USA. nmgloria@depaul.edu AB - The present study focused on coping strategies among African Americans, Latinos, and European Americans with chronic fatigue syndrome (CFS) and idiopathic chronic fatigue (ICF). The coping strategies examined were measured by using the COPE Scales, which assess Seeking Emotional Social Support, Positive Reinterpretation and Growth, Acceptance, Denial, Turning to Religion, Behavioral Disengagement, and Focusing on and Venting Emotions. In addition, the four coping strategies specifically designed for people with CFS, including maintaining activity, accommodating to the illness, focusing on symptoms, and information-seeking, were used in this study. It was hypothesized that African Americans and Latinos in comparison to European Americans would be more likely to use religious coping, behavioral disengagement, and denial. As predicted, African Americans were significantly more likely to turn to religion than European Americans, and Latinos and African Americans used denial significantly more often than European Americans. An additional finding was that focusing on symptoms was associated with greater fatigue and more physical disability among African Americans. Within the Latino sample, acceptance was related to greater fatigue and less physical disability, and greater optimism predicted less mental disability. Among European American participants, maintaining activity was related to less mental disability, whereas accommodating to the illness predicted more physical disability. These results indicate that coping varies among various ethnic groups with CFS and ICF; however, denial is consistently related to less adaptive outcomes. Therefore, healthcare professionals should find ways to reduce patient use of denial and promote alternative strategies for managing life events. 216 PMID- 15902759 AU - Offenbaecher M, Ackenheil M TI - Current trends in neuropathic pain Rxs w special reference to FM.

Martin.Offenbaecher@med.uni-muenchen.de AB - Neuropathic pain and fibromyalgia are prevalent diseases which have major consequences on healthcare resources and the individual. From the clinical point of view neuropathic pains represent a heterogeneous group of aetiologically different diseases ranging from cancer to diabetes. Patients with fibromyalgia also display clinical features common in neuropathic pain suggesting that there might be some overlap. The mechanisms responsible for symptoms and signs in both diseases are still unknown. Recently, there have been numerous reports of various pharmacological treatments of neuropathic pain and fibromyalgia with often disappointing results. Most of the studies were of short duration, had high attrition rates, and displayed other methodological problems. Some compounds had high rates of adverse effects which makes it often difficult for the patients to tolerate the treatment, especially in the long-term. At present, the best options for medication treatment are tricyclic antidepressants in lower dosage than usual in psychiatric disorders and a wide range of anticonvulsants. Opioids are sometimes recommended but have been found to have minor efficacy. Recently, there have been more controlled trials, which are reported here if they had been published between 2002 and 2004. Various compounds have been tested in different studies. Treatment of fibromyalgia, which has many features in common with depressive symptoms, became the focus of interest. New promising studies with dual serotonin-norepinephrine reuptake inhibitors (duloxetine and milnacipram) and a newer antiepileptic drug (pregabalin) are in progress. Future research will have to apply new approaches (e.g., using a mechanism-based classification of neuropathic pain and carrying out studies in populations with the same symptom but not necessarily the same disease) in order to find effective treatments for these common and often debilitating diseases. 217 PMID- 15856367 AU - Ofluoglu D, Berker N, Guven Z, Canbulat N, Yilmaz IT, Kayhan O TI - Quality of life in pts w FM syndrome & RA.

This prospective study included 62 female FS patients and 60 female RA patients diagnosed by the American College of Rheumatology criteria. The Turkish translations of the Arthritis Impact Measurement Scale II (AIMS II) and Beck Depression Index (BDI) were given to all of the patients and they were asked to complete the two questionnaires. The scores of AIMS II, pain, and QOL were evaluated in the FS and RA groups. There were no statistically significant differences between the FS and RA groups (p>0.05) in terms of QOL. The affect subgroup scores of the AIMS II and BDI were highly correlated in the FS and RA groups (p<0.002, r=0.85 and p<0.05, r=0.80, respectively). The results show that the QOL is negatively but similarly affected in FS and RA groups. 218 PMID- 15642872 AU - Ohayon MM TI - Prevalence & correlates of nonrestorative sleep complaints.

IN - Stanford Sleep Epidemiology Research Ctr, Stanford U School o Med, Stanford, Calif., USA. mohayon@stanford.edu AB - BACKGROUND: Nonrestorative sleep (NRS) has been little studied in the general population, even though this symptom has an important role in several medical conditions such as heart disease, fibromyalgia, and chronic fatigue syndrome, as well as various sleep disorders. METHODS: A total of 25,580 individuals (age range, 15-100 years) from the noninstitutionalized general population representative of 7 European countries (France, the United Kingdom, Germany, Italy, Portugal, Spain, and Finland) were interviewed by telephone using the Sleep-EVAL system. Nonrestorative sleep was analyzed in relationship to sociodemographic determinants, environmental factors, life habits, health, sleep-wake schedule, and psychological factors. RESULTS: The prevalence of NRS was 10.8% (95% confidence interval, 10.4%-11.2%) in the sample, was higher in women than in men (12.5% vs 9.0%; P<.001), and decreased with age. The United Kingdom (16.1%) and Germany (15.5%) had the highest prevalence of NRS and Spain (2.4%), the lowest. In multivariate analyses, several factors were positively associated with NRS. The most important were younger age, dissatisfaction with sleep, difficulty getting started in the morning, stressful life, presence of anxiety, bipolar or a depressive disorder, and having a physical disease. When compared with subjects who have difficulty initiating or maintaining sleep (without NRS), subjects with NRS reported more frequently a variety of daytime impairment (irritability, physical, and mental fatigue) and consulted a physician twice as frequently for their sleeping difficulties than did other subjects with insomnia. CONCLUSIONS: Nonrestorative sleep is a frequent symptom in the general population, but its prevalence largely varies between countries. It is often associated with mental disorders and characteristics of sleep deprivation (such as extra sleep time on weekends). Nonrestorative sleep affected more frequently the active classes of the population and caused greater daytime impairment than difficulty initiating or maintaining sleep. 219 PMID- 15677300 AU - Oliver K, Cronan TA TI - Correlates of physical activity among women w FM syndrome.

AB - BACKGROUND: Fibromyalgia (FMS) is a chronic pain syndrome of unknown origin that lacks standardized treatment. However, participation in physical activity (PA) benefits people with FMS. Despite the psychosocial and health benefits that can be gained through PA, the correlates of PA among people with FMS remain poorly understood. PURPOSE: The purpose of this study was to identify and compare the effects of cross-sectional and longitudinal correlates of PA among women with FMS. METHODS: Participants were 187 female members of a HMO with a confirmed diagnosis of FMS. They were administered a battery of questionnaires assessing potential correlates of PA. These correlates were suggested by social cognitive theory and the transtheoretical model, and have been repeatedly associated with PA among the general population. RESULTS: Multivariate analyses indicated that self-efficacy for PA and the behavioral processes of change were the strongest discriminators among PA adopters, maintainers, quitters, and those who were sedentary. Enjoyment of PA, barriers to PA, the impact of FMS, and the environment also significantly discriminated among these groups. Longitudinally, changes in self-efficacy were significantly associated with changes in PA. CONCLUSIONS: These findings suggest that self-efficacy may play a critical role in both the present and long-term PA of women with FMS. They also lend additional support to the role of social cognitive and transtheoretical variables in discriminating among levels of PA. 220 PMID- 12961098 AU - Otero M, Nogueiras R, Lago F, Meijide J, Amarelo J, Mera A, Gomez-Reino J, Gualillo O TI - Ghrelin plasmatic levels in pts w FM.

AB - Ghrelin is a recently discovered 28 amino acid peptide that regulates GH secretion and energy homeostasis. In fibromyalgia (FM) there are alterations in the pituitary-hypothalamic axis, particularly in the growth hormone (GH) secretion pattern. Whether this anomalous secretion of GH pertains to abnormal levels of ghrelin is still unknown. The purpose of this study was to investigate plasma ghrelin levels in patients with fibromyalgia (FM) compared with healthy controls. Plasmatic ghrelin concentrations were determined by a double antibody radioimmunoassay in 19 patients with FM and 14 healthy controls. Compared with controls, patients with FM did not show any significant differences of ghrelin plasmatic levels. In conclusion, FM is not associated with deviation in ghrelin concentrations. Existing alterations in FM with respect to GH are unlikely due to circulating ghrelin. 221 PMID- 16396694 AU - Pamuk ON, Cakir N TI - The variation in chr widespread pain & other Sx in FM pts.

In addition, we compared the clinical features of FM patients diagnosed pre-and postmenopausally. METHODS: We included 80 premenopausal, and 72 postmenopausal patients with FM. All patients were questioned about the severity of their pain and symptoms of FM by using a visual analog scale (VAS). In addition, the patients were asked questions about symptoms of somatization, depression and anxiety. Postmenopausal subjects were asked about the change in their FM symptoms with the onset of menopause; and premenopausal subjects were asked whether their FM symptoms changed during the menses. In addition, 40 premenopausal patients were requested to fill in a diary about their FM symptoms using VAS throughout one menstrual cycle. RESULTS: Postmenopausal patients had more severe pain on VAS (p = 0.048). Of all the postmenopausal females, 25% said that their FM symptoms started with the onset of menopause and 26.4% said that the severity of their previous symptoms increased after menopause. Of all the premenopausal females, 45% admitted to higher pain severity and 57.5% to a higher fatigue severity during the menses. The patients who defined an increase in their symptoms during the menses were the ones with higher sleep disturbance scores, more somatization symptoms and more tender points (p values < 0.05). The results of the diaries revealed that the mean pain and fatigue scores in the menstrual and luteal phases were higher than the scores in the follicular and premenstrual phases (p values < 0.05). CONCLUSIONS: The menstrual cycle and the onset of menopause affect pain and the severity of other FM-related symptoms in approximately one half of the subjects. 222 PMID- 15790342 AU - Pasoto SG, Abrao MS, Viana VS, Bueno C, Leon EP, Bonfa E TI - Endometriosis & SLE: a comparative evaluation of clinical manifestations & serological autoimmune phenomena.

METHOD OF STUDY: Forty-five women (18-40 years) with histologically confirmed pelvic EM, 21 healthy-women and 15 female SLE-patients (18-40 years) without surgically confirmed EM were prospectively evaluated. Immunologic investigations were performed by blinded researchers. RESULTS: None of the EM-patients fulfilled criteria for SLE. However, EM-patients presented higher frequencies of arthralgia (62%) and generalized myalgia (18%) superior than normal-controls (24%, P = 0.004/0%, P = 0.048) but comparable with SLE-patients (33%, P = 0.052/27%, P = 0.5). Similarly to SLE (7%), 9% of EM-patients presented fibromyalgia. Antinuclear antibodies (ANA) were detected in 18% of EM-sera, as compared with healthy-women (0%, P = 0.014) and SLE-patients (93%, P = 0.0005). In contrast with SLE, antibodies to dsDNA, Sm and U1RNP were negative in EM-sera. Anti-Ro and anticardiolipin antibodies were more often in SLE (40%, 33%) than in EM-patients (2%, P < 0.001/9%, P = 0.04). Elevated immune-complexes and low total complement were more frequent in SLE (40%, 13%) compared with EM-sera (7%, P = 0.005/0%, P = 0.01). CONCLUSIONS: Our data indicate differences of ANA antigenic specificity and complement consumption between EM and SLE. The high prevalence of generalized musculoskeletal complaints in EM justifies a multidisciplinary approach. 223 PMID- 15898458 AU - Patten SB, Beck CA, Kassam A, Williams JV, Barbui C, Metz LM TI - Long-term medical conditions & major depression: strength of association for specific conditions in the general population.

IN - D o Community Health Sciences, U o Calgary, Alberta. patten@ucalgary.ca AB - BACKGROUND: The prevalence of major depression (MD) in persons with nonpsychiatric medical conditions is an indicator of clinical need in those groups, an indicator of the feasibility of screening and case-finding efforts, and a source of etiologic hypotheses. This analysis explores the prevalence of MD in the general population in relation to various long-term medical conditions. METHODS: We used a dataset from a large-scale Canadian national health survey, the Canadian Community Health Survey (CCHS). The sample consisted of 115 071 subjects aged 18 years and over, randomly sampled from the Canadian population. The survey interview recorded self-reported diagnoses of various long-term medical conditions and employed a brief predictive interview for MD, the Composite International Diagnostic Interview Short Form for Major Depression. Logistic regression was used to adjust estimates of association for age and sex. RESULTS: The conditions most strongly associated with MD were chronic fatigue syndrome (adjusted odds ratio [AOR] 7.2) and fibromyalgia (AOR 3.4). The conditions least strongly associated were hypertension (AOR 1.2), diabetes, heart disease, and thyroid disease (AOR 1.4 in each case). We found associations with various gastrointestinal, neurologic, and respiratory conditions. CONCLUSIONS: A diverse set of long-term medical conditions are associated with MD, although previous studies might have lacked power to detect some of these associations. The strength of association in prevalence data, however, varies across specific conditions. 224 PMID- 16155813 AU - Perez-Pareja J, Borras C, Sese A, Palmer A TI - Pain perception & FM.

AB - INTRODUCTION: Although psychological factors and self-regulation processes rarely cause pain they have enough importance to exacerbate pain and contribute to its maintenance. Nevertheless, pain perception and associated beliefs can influence its confrontation and the sensation of intensity. Pain perception in fibromyalgia acquires special relevance due to an abnormal sensitivity to digital pressure on the so-called "tender points". This constitutes the main factor for its differential diagnosis. METHOD: The aim of the present study is to determine differences in pain perception and associated beliefs that appear between a group of patients with fibromyalgia (n = 36), a control group with chronic pain with objectified non-inflammatory locomotion apparatus pathology (n = 44) and a control group with healthy subjects (n = 31). Pain perception and beliefs concerning pain were assessed using Spanish versions of the following self-reports: West Haven Yale Multidimensional Questionnaire (WHYWP) and Pain Perceptions and Beliefs Inventory (PBAPI). RESULTS: Results show that the difference between patients with chronic pain is not related to pain global perception, but rather to greater perception of pain as more incapacitating when carrying out every day activities in fibromyalgic patients. In this sense, these people use escape-avoidance strategies in their every day lives believing that pain incapacitates them and therefore that physical activity should be avoided. CONCLUSIONS: Measurement of pain perceptions and beliefs could be considered relevant for assessment and for intervention programs on pathologies associated with chronic pain. 225 PMID- 15862482 AU - Petzke F, Harris RE, Williams DA, Clauw DJ, Gracely RH TI - Differences in unpleasantness induced by experimental pressure pain between pts w FM & healthy controls. SO - Eur J Pain. 2005 Jun;9(3):325-35. IN - D o Anesthesiology o the U o Cologne, Germany. AB - Pain possesses both sensory and affective dimensions, which are highly correlated yet distinct. Comparison of these dimensions within experimental pain settings has resulted in the construct of relative unpleasantness. Relative unpleasantness is defined as the amount of affective unpleasantness elicited for a given sensory magnitude. The aim of this study was to determine the relationship between affective and sensory components of evoked pain in subjects with fibromyalgia (FM) and healthy controls. Here we show that patients with FM unexpectedly display less relative unpleasantness than healthy controls in response to random noxious pressure stimuli. Relative unpleasantness was not correlated with distress, anxiety, or depression, which were pronounced in the FM group. Clinical pain in patients with FM was perceived to be more unpleasant than the evoked pain stimuli. These results are consistent with the concept that chronic pain may reduce the relative unpleasantness of evoked pain sensations. 226 PMID- 16009690 AU - Piche T, Vanbiervliet G, Cherikh F, Antoun Z, Huet PM, Gelsi E, Demarquay JF, Caroli-Bosc FX, Benzaken S, Rigault MC, Renou C, Rampal P, Tran A TI - Effect of ondansetron, a 5-HT3 receptor antagonist, on fatigue in chr hepatitis C: a randomised, double blind, placebo controlled study.

IN - D o Hepatogastroenterology, Chu de Nice, France. tpiche@fc.horus-medical.fr AB - BACKGROUND AND AIMS: There are no available effective therapies for fatigue associated with chronic hepatitis C (CHC). The serotonin antagonist ondansetron has been shown to be effective in the chronic fatigue syndrome. In this randomised, placebo controlled, double blind trial, we investigated the effect of orally administered ondansetron on fatigue in CHC. METHODS: Thirty six patients with CHC were included if fatigue was their predominant symptom and they scored more than 4 on a visual analogue scale (0-10). During the study, fatigue and depression were measured on days 0, 15, 30, and 60 using a validated self report questionnaire (fatigue impact scale and Beck depression inventory). Patients were randomised to receive ondansetron tablets 4 mg twice daily or placebo for one month followed by an additional four weeks of observation. RESULTS: Fatigue score was 85.4 (28.2) and 98.2 (26.9) in the ondansetron and placebo groups, respectively (NS). Ondansetron significantly reduced the fatigue score with more than 30% improvement on day 15 (57.1 (38.9); p<0.01), day 30 (54.5 (37.6); p<0.01), and day 60 (60.8 (37.3); p<0.01) whereas placebo did not. Overall, the reduction in fatigue was significantly higher with ondansetron compared with placebo (ANOVA for repeated measurements) for the whole follow up period (p = 0.03) or for the treatment period only (p = 0.04). Ondansetron also significantly reduced depression scores. CONCLUSIONS: The 5-hydroxytryptamine receptor type 3 antagonist ondansetron had a significant positive effect on fatigue in CHC. These observations support the concept that fatigue involves serotoninergic pathways and may encourage further evaluations of the efficacy of ondansetron on fatigue in chronic liver diseases. 227 PMID- 16214660 AU - Pierrynowski MR, Tiidus PM, Galea V TI - Women w FM walk w an altered muscle synergy.

IN - Human Movement Laboratory, School o Rehabilitation Science, McMaster U, Hamilton, Ontario, Canada. pierryn@mcmaster.ca AB - Most individuals can use different movement and muscle recruitment patterns to perform a stated task but often only one pattern is selected which optimizes an unknown global objective given the individual's neuromusculoskeletal characteristics. Patients with fibromyalgia syndrome (FS), characterized by their chronic pain, reduced physical work capacity and muscular fatigue, could exhibit a different control signature compared to asymptomatic control volunteers (CV). To test this proposal, 22 women with FS, and 11 CV, were assessed in a gait analysis laboratory. Each subject walked repeatedly at self-selected slow, comfortable, and fast walking speeds. The gait analysis provided, for each walk, each subject's stride time, length, and velocity, and ground reaction force, and lower extremity joint kinematics, moments and powers. The data were then anthropometrically scaled and velocity normalized to reduce the influence of subject mass, leg length, and walking speed on the measured gait outcomes. Similarities and differences in the two groups' scaled and normalized gait patterns were then determined. Results show that FS and CV walk with externally similar stride lengths, times, and velocities, and joint angles and ground reaction forces but they use internally different muscle recruitment patterns. Specifically, FS preferentially power gait using their hip flexors instead of their ankle plantarflexors. Interestingly, CV use a similar muscle fatiguing recruitment pattern to walk fast which parallels the common complaint of fatigue reported by FS walking at comfortable speed. 228 PMID- 16078357 AU - Price DD, Staud R TI - Neurobiology of FM syndrome. SO - J Rheumatol Suppl. 2005 Aug;75:22-8. IN - D o Neuroscience, U o Florida, Gainesville, Florida, USA. Dprice@dental.ufl.edu AB - Accumulating evidence suggests that fibromyalgia syndrome (FM) pain is maintained by tonic impulse input from deep tissues, such as muscle and joints, in combination with central sensitization mechanisms. This nociceptive input may originate in peripheral tissues (trauma and infection) resulting in hyperalgesia/allodynia and/or central sensitization. Evidence for abnormal sensitization mechanisms in FM includes enhanced temporal summation of delayed pain in response to repeated heat taps and repeated muscle taps, as well as prolonged and enhanced painful after-sensations in FM patients but not control subjects. Moreover, magnitudes of enhanced after-sensations are predictive of FM patients' ongoing clinical pain. Such alterations of relevant pain mechanisms may lead to longterm neuroplastic changes that exceed the antinociceptive capabilities of affected individuals, resulting in ever-increasing pain sensitivity and dysfunction. Future research needs to address the important role of abnormal nociception and/or antinociception for chronic pain in FM. 229 PMID- 16055833 AU - Prins J, Bleijenberg G, Rouweler EK, van der Meer J TI - Effect of psychiatric disorders on outcome of cognitive-behavioural therapy for CFS.

No significant differences in fatigue severity and functional impairment following treatment were found between participants with and without psychiatric diagnoses. 230 PMID- 15836975 AU - Pukall CF, Strigo IA, Binik YM, Amsel R, Khalife S, Bushnell MC TI - Neural correlates of painful genital touch in women w vulvar vestibulitis syndrome.

IN - D o Psychology, Queen's U, Humphrey Hall, 62 Arch Street, Kingston, Ont., Canada K7L 3N6. pukallc@post.queensu.ca AB - Vulvar vestibulitis syndrome (VVS) is a common cause of dyspareunia in pre-menopausal women. Recent evidence points to the importance of the sensory component in VVS, particularly the heightened processing of tactile and pain sensation in the vulvar vestibule. The goal of the present study was to examine the neural basis of heightened sensitivity to touch (i.e. allodynia) in women with VVS. Using functional magnetic resonance imaging, we compared regions of neural activity in 14 women with VVS and 14 age- and contraceptive-matched control women in response to the application of mild and moderate pressure to the posterior portion of the vulvar vestibule. Intensity and unpleasantness ratings were recorded after each scan; these ratings were significantly higher for women with VVS than controls. All women with VVS described moderate pressure as painful and unpleasant, and 6 of the 14 women with VVS described mild pressure as painful and unpleasant. In contrast, none of the stimuli was painful for control women. Correspondingly, women with VVS showed more significant activations during pressure levels that they found to be either painful or non-painful than did controls during comparable pressure levels. During pressure described as painful by women with VVS, they had significantly higher activation levels in the insular and frontal cortical regions than did control women. These results suggest that women with VVS exhibit an augmentation of genital sensory processing, which is similar to that observed for a variety of syndromes causing hypersensitivity, including fibromyalgia, idiopathic back pain, irritable bowel syndrome, and neuropathic pain. 231 PMID- 15789937 AU - Rakib A, White PD, Pinching AJ, Hedge B, Newbery N, Fakhoury WK, Priebe S TI - Subjective quality of life in pts w CFS. SO - Qual Life Res. 2005 Feb;14(1):11-9. IN - Queen Mary's School o Med & Dentistry, Newham Centre for Mental Health, London, UK. AB - The aim of this study was to (1) assess Subjective Quality of Life (SQOL) of patients with Chronic Fatigue Syndrome (CFS) using a generic concept and to compare the findings with those in groups with mental disorders and healthy subjects, and (2) investigate whether and, if so, to what extent socio-demographic and clinical variables predict SQOL in CFS patients. Seventy-three patients diagnosed with CFS were randomly selected and interviewed from two specialised clinics. CFS was diagnosed using the Oxford Criteria. SQOL was assessed on the Manchester Short Assessment of Quality of Life (MANSA) and Health-Related Quality of Life (HRQOL) on the Medical Outcome Study Short-Form 36 (MOS) SF-36. A battery of mood and symptom questionnaires, including the Symptom Checklist Questionnaire (SCL-90-R), was administered to assess various aspects of symptomatology as potential predictor variables. Multiple regression analyses were conducted to identify predictors of SQOL. Overall, SQOL was low in CFS patients and less favourable than in groups with mental disorders and healthy subjects. Satisfaction was particularly low with life as a whole, leisure activities and financial situation. Whilst SQOL was only moderately correlated with HRQOL, the SCL-90-R score, especially SCL-90-R Depression scale score, was the best predictor of SQOL explaining 35% of the variance. HRQOL and generic SQOL appear distinct despite some overlap. The findings underline that SQOL is significantly disrupted in CFS patients. Depressive symptoms are statistically the strongest 'predictor' of SQOL, although the direction of the relationship is not established. These data suggest that treatment of depression associated with CFS, regardless of causation, could help to improve SQOL in CFS patients. 232 PMID- 16272188 AU - Randall DC, Cafferty FH, Shneerson JM, Smith IE, Llewelyn MB, File SE TI - Chronic Rx w modafinil may not be beneficial in pts w CFS. SO - J Psychopharmacol. 2005 Nov;19(6):647-60. IN - Psychopharmacology Research Unit, Centre for Neuroscience Research, King's Coll London, London, UK. AB - Fourteen patients (7 male, 7 female, 22-63 years), classified as having chronic fatigue syndrome (CFS), but without concurrent major depression, significant sleepiness or use of psychoactive medication, completed a double-blind, placebo-controlled, crossover study of the effects of the selective wakefulness-promoting agent, modafinil (200 and 400mg/day). The treatment periods were each 20 days, with washout periods of 2 weeks. The primary aim was to determine effects on cognition and the secondary aim was to determine effects on self-ratings of fatigue, quality of life and mood. Modafinil had mixed effects in two cognitive tasks. In a test of sustained attention, treatment with 200mg reduced the latency to correctly detect sequences, but 400mg increased the number of missed targets. In a test of spatial planning, the 200mg dose resulted in a slower initial thinking time for the easiest part of the task, whereas 400mg reduced the initial thinking time for the hardest part of the test. Lastly, in a test of mental flexibility and one of motor speed, patients performed worse whilst on modafinil (400mg), compared with the placebo period. No effects were observed on the performance of other psychometric tests or on self-ratings of fatigue, quality of life or mood, but this may have been due to insufficient statistical power. It is discussed whether the limited and mixed cognitive effects that we observed could have occurred by chance, or whether a subgroup of CFS patients with daytime sleepiness would have shown greater benefits. 233 PMID- 15689728 AU - Rangel L, Garralda ME, Jeffs J, Rose G TI - Family health & characteristics in CFS, juvenile RA, & emotional disorders of childhood.

AB - OBJECTIVE: To compare family health and characteristics in children with chronic fatigue syndrome (CFS), in juvenile rheumatoid arthritis (JRA), and emotional disorders. METHOD: Parents of 28 children and adolescents aged 11 to 18 years with CFS, 30 with JRA, and 27 with emotional disorders (i.e., anxiety and/or depressive disorders) were recruited from specialty clinical settings and completed interviews and questionnaires assessing family health problems, parental mental distress, illness attitudes, and family burden of illness. RESULTS: Parents of children with CFS were significantly more likely than those of children with JRA to report a history of CFS-like illness, high levels of mental distress, and a tendency to experience functional impairment in response to physical symptoms. Families of children with CFS were characterized by significantly greater emotional involvement and reported greater family burden related to the child's illness in comparison with families of children with JRA. CONCLUSIONS: CFS in childhood and adolescence is associated with higher levels of parental CFS-like illness, mental distress, emotional involvement, and family illness burden than those observed in association with JRA, a chronic pediatric physical illness. 234 PMID- 15699086 AU - Ranjith G TI - Epidemiology of CFS.

IN - D o Psychological Med, King's Coll Hosp, London, UK. g.ranjith@iop.kcl.ac.uk AB - BACKGROUND: Chronic fatigue syndrome (CFS) is a controversial disorder with different case definitions, aetiological models and proposed treatments. An epidemiological approach is likely to bring some clarity to the field. AIM: The aim of this article is to review the literature on the epidemiology of fatigue, chronic fatigue and CFS. METHOD: A literature search was conducted using the databases Medline and Pubmed as well as the reference lists of recent reviews to identify the relevant studies. The aim was not to do a systematic review but to review the key studies in the area to highlight the methodological issues. RESULTS: The review is organized according to the following areas: the prevalence of fatigue and chronic fatigue, the prevalence and incidence of CFS, epidemiological associations such as gender, social class and psychiatric co-morbidity and CFS in special groups such as those recovering from a viral infection, specific occupational groups and Gulf War veterans. CONCLUSION: While fatigue as a symptom is very common, CFS is relatively rare. Many of the epidemiological associations seen in specialist clinics are not found in community samples. It is unlikely that one specific causal factor can explain CFS. Future studies should go beyond estimating the prevalence to testing more complex aetiological models. 235 PMID- 16356178 AU - Reeves WC, Wagner D, Nisenbaum R, Jones JF, Gurbaxani B, Solomon L, Papanicolaou DA, Unger ER, Vernon SD, Heim C TI - CFS--a clinically empirical approach to its definition & study.

IN - Division o Viral & Rickettsial Diseases, Centers for Disease Control & Prevention, Atlanta, GA, USA. wcr1@cdc.gov AB - BACKGROUND: The lack of standardized criteria for defining chronic fatigue syndrome (CFS) has constrained research. The objective of this study was to apply the 1994 CFS criteria by standardized reproducible criteria. METHODS: This population-based case control study enrolled 227 adults identified from the population of Wichita with: (1) CFS (n = 58); (2) non-fatigued controls matched to CFS on sex, race, age and body mass index (n = 55); (3) persons with medically unexplained fatigue not CFS, which we term ISF (n = 59); (4) CFS accompanied by melancholic depression (n = 27); and (5) ISF plus melancholic depression (n = 28). Participants were admitted to a hospital for two days and underwent medical history and physical examination, the Diagnostic Interview Schedule, and laboratory testing to identify medical and psychiatric conditions exclusionary for CFS. Illness classification at the time of the clinical study utilized two algorithms: (1) the same criteria as in the surveillance study; (2) a standardized clinically empirical algorithm based on quantitative assessment of the major domains of CFS (impairment, fatigue, and accompanying symptoms). RESULTS: One hundred and sixty-four participants had no exclusionary conditions at the time of this study. Clinically empirical classification identified 43 subjects as CFS, 57 as ISF, and 64 as not ill. There was minimal association between the empirical classification and classification by the surveillance criteria. Subjects empirically classified as CFS had significantly worse impairment (evaluated by the SF-36), more severe fatigue (documented by the multidimensional fatigue inventory), more frequent and severe accompanying symptoms than those with ISF, who in turn had significantly worse scores than the not ill; this was not true for classification by the surveillance algorithm. CONCLUSION: The empirical definition includes all aspects of CFS specified in the 1994 case definition and identifies persons with CFS in a precise manner that can be readily reproduced by both investigators and clinicians. 236 PMID- 15621381 AU - Reid GJ, McGrath PJ, Lang BA TI - Parent-child interactions among children w juvenile FM, arthritis, & healthy controls. SO - Pain. 2005 Jan;113(1-2):201-10. IN - Psychology, IWK Health Centre & Dalhousie U, Halifax, NS, Canada. greid@uwo.ca AB - Parent-child interactions during pain-inducing exercise tasks among children (11-17 years old) with fibromyalgia, juvenile rheumatoid arthritis, and pain-free controls were examined and the contribution of parent-child interactions to disability was tested. Fifteen children in each of the three diagnostic groups and their parents completed 5-min exercise tasks and completed questionnaire measures of disability (Functional Disability Inventory) and coping (Pain Coping Questionnaire). There were few group differences in parent-child interactions. After controlling for children's ratings of pain evoked by the exercise, group differences in interactions during exercise tasks were no longer significant. Sequential analyses, controlling for group and exercise task, revealed that when parents made statements discouraging coping following children's negative verbalizations about the task or pain, children were less likely to be on task, compared to when parents made statements encouraging coping or when parents made any other statements. Children's general pain coping strategies were not related to parent-child interactions. Parent-child interactions were generally not related to disability. Across the groups, more pain and less time on task during the exercises were related to Functional Disability Inventory scores and more school absences. Parent-child interaction patterns influence children's adaptation to pain during experimental tasks. Parents' discouragement of coping in response to their children's negative statements related to the pain or the pain-evoking task are counter productive to children's ability to maintain activity in a mildly painful situation. 237 PMID- 16372472 AU - Ribel-Madsen S, Gronemann ST, Bartels EM, Danneskiold-Samsoe B, Bliddal H TI - Collagen structure in skin from FM pts.

Skin biopsies were obtained from the front of the thigh of 27 females who fulfilled the American College of Rheumatology criteria of fibromyalgia and from eight control subjects who were matched for gender, age and physical activity. Amino acids were determined by high-performance liquid chromatography. Electron and light microscopic investigations were carried out to examine tissue structure. Among the collagen-related amino acids, the mean number of hydroxyproline residues per 1,000 residues was 52.5 and 63.4 in fibromyalgia patients and control subjects, respectively (p = 0.050); proline residues were 81.7 and 110.0 (p = 0.006); and hydroxylysine residues were 14.7 and 10.1 (p = 0.002). The total amount of skin protein in proportion to dry tissue weight was 83.4% and 72.6% in fibromyalgia and controls, respectively (p = 0.037). The overall microscopic picture was normal. The lamellar structure of the perineurium and a deficiency in collagen packing in the endoneurium was observed more frequently and to a larger extent in fibromyalgia patients than in controls. In conclusion, there are some differences between the amino acid composition of skin proteins in fibromyalgia patients compared with controls. The amount of collagen may be lower in skin from fibromyalgia patients, and collagen packing in the endoneurium may be less dense. 238 PMID- 16220215 AU - Richards J, Turk J, White S TI - Children & adolescents w CFS in non-specialist settings: beliefs, functional impairment & psychiatric disturbance.

AB - BACKGROUND: Adolescents with Chronic Fatigue Syndrome (CFS) seen in specialist centres have substantial psychological and functional impairment. Beliefs about activity levels may be important in the development of CFS. METHOD: The aim was to investigate psychological and functional impairment, and beliefs in children and adolescents with CFS recruited from non-specialist services. A total of 30 such individuals participated, and 30 young people with Inflammatory Bowel Disease (IBD) formed the comparison group. RESULTS: Emotional symptoms and disorder were high in both groups. In all, 50% of those with CFS and 30% with IBD reached the threshold for emotional disorder according to the Strengths and Difficulties Questionnaire (SDQ) parent report, although this difference did not reach statistical significance. Participants with CFS scored statistically significantly higher on measures of functional impairment, including school non-attendance, compared to those with IBD. According to questionnaire responses, those with CFS were statistically significantly more likely to favour rest rather than exercise compared to those with IBD. Comparison of parental beliefs did not show such a difference. CONCLUSIONS: These young people with CFS were at high risk of psychiatric disorder. They were substantially disabled when compared to individuals with a known chronic illness. Also, as a group, they were characterised by a preference for rest rather than exercise. 239 PMID- 15610961 AU - Rico-Villademoros F, Hidalgo J, Dominguez I, Garcia-Leiva JM, Calandre EP TI - Atypical antipsychotics in the Rx of FM: a case series w olanzapine. SO - Prog Neuropsychopharmacol Biol Psychiatry. 2005 Jan;29(1):161-4. IN - Biometrica, Departamento Medico, Eloy Gonzalo 27, 28010 Madrid, Spain. AB - Fibromyalgia is a common and disabling chronic pain syndrome. Although a wide array of symptomatic pharmacological treatments has been used to treat this condition, only modest results have been obtained. Olanzapine has been proven effective in some chronic pain conditions. The authors present a case series of patients suffering from fibromyalgia who received olanzapine as add-on therapy during a 3-month period. Olanzapine (2.5-20.0 mg/day) was administered to 25 consecutive patients (24 females, 1 male) meeting the American College of Rheumatology diagnostic criteria for fibromyalgia, and who were receiving nonsteroidal anti-inflammatory drugs (NSAIDs; 68%), benzodiazepines/zolpidem (48%), antidepressants (32%), and cyclobenzaprine (4%), either alone or in combination. Overall, 6 of the 14 patients (43%) who completed the 12-week trial reported to be much or very much improved ('responders'), according to the Clinical Global Impression (CGI) scale and 7 of them (50%) reported a good or very good sense of well-being. Olanzapine's modal dose among responders was 10.0 mg/day. It was discontinued in 11 patients (44%) due to adverse reactions, most commonly weight gain (n=5, 20%). Our preliminary findings suggest a possible role for olanzapine in treating fibromyalgia. Unfortunately, the beneficial outcome of olanzapine was largely obscured by its poor tolerability, which could be explained by the greater propensity of patients with fibromyalgia to adverse drug reactions, and the greater risk of antipsychotic-induced weight gain among women. Whether other atypical antipsychotics will provide similar symptomatic relief, while showing a better tolerability profile than olanzapine in patients with fibromyalgia, should be further investigated. 240 PMID- 15699088 AU - Rimes KA, Chalder T TI - Treatments for CFS.

METHODS: A literature search was carried out using Medline and PsychInfo. RESULTS: Studies evaluating cognitive behaviour therapy, graded exercise therapy, pharmacological interventions (e.g. antidepressants and corticosteroids), immunological interventions and nutritional supplements were reviewed. The most promising results have been found with cognitive behaviour therapy and graded exercise therapy, and some predictors of outcome have been identified. Most of the other interventions were evaluated in just one or two studies and therefore evidence is insufficient to draw firm conclusions. CONCLUSIONS: By applying the models of fatigue that form the bases for cognitive behaviour therapy and graded exercise therapy, occupational health physicians may play an important role in helping the patients with chronic fatigue syndrome to reduce their symptoms, improve their functioning and return to work. 241 PMID- 15996197 AU - Robertson MJ, Schacterle RS, Mackin GA, Wilson SN, Bloomingdale KL, Ritz J, Komaroff AL TI - Lymphocyte subset differences in pts w CFS, multiple sclerosis & major depression.

Many studies demonstrate probable involvement of the central and autonomic nervous system, as well as a state of generalized immune activation and selective immune dysfunction in patients with CFS. The aim of this study was to compare the lymphocyte subsets of patients with chronic fatigue syndrome to those of patients with major depression and multiple sclerosis as well as those of healthy control subjects. No differences were found in total numbers of T cells, B cells or natural killer (NK) cells. However, differences were found in T, B and NK cell subsets. Patients with major depression had significantly fewer resting T (CD3(+)/CD25(-)) cells than the other groups. Patients with major depression also had significantly more CD20(+)/CD5(+) B cells, a subset associated with the production of autoantibodies. Compared to patients with multiple sclerosis, patients with CFS had greater numbers of CD16(+)/CD3(-) NK cells. Further study will be required to determine whether these alterations in lymphocyte subsets are directly involved in the pathophysiology of these disorders, or are secondary effects of the causal agent(s). 242 PMID- 16078359 AU - Rowbotham MC TI - Is FM a neuropathic pain syndrome? SO - J Rheumatol Suppl. 2005 Aug;75:38-40. IN - U o California San Francisco Pain Clinical Research Ctr, San Francisco, California 94115, USA. mcrwind@itsa.ucsf.edu AB - The fibromyalgia syndrome (FM) seems an unlikely candidate for classification as a neuropathic pain. The disorder is diagnosed based on a compatible history and the presence of multiple areas of musculoskeletal tenderness. A consistent pathology in either the peripheral or central nervous system (CNS) has not been demonstrated in patients with FM, and they are not at higher risk for diseases of the CNS such as multiple sclerosis or of the peripheral nervous system such as peripheral neuropathy. A large proportion of FM sufferers have accompanying symptoms and signs of uncertain etiology, such as chronic fatigue, sleep disturbance, and bowel/bladder irritability. With the exception of migraine headaches and possibly irritable bowel syndrome, the accompanying disorders are clearly not neurological in origin. The impetus to classify the FM as a neuropathic pain comes from multiple lines of research suggesting widespread pain and tenderness are associated with chronic sensitization of the CNS. An examination of how the term neuropathic pain is defined reveals a conceptual split into 2 partially overlapping groups of disorders: those with demonstrable pathology in the nervous system and those characterized primarily by enduring dysfunction in the nervous system. Requiring demonstrable pathology in the nervous system in the definition of neuropathic pain is the traditional approach. The expansion of the definition to require only enduring nervous system dysfunction is less palatable because it opens the classification to many disorders of uncertain etiology, including complex regional pain syndrome. As it is uncertain which of the many different chronic pain syndromes include an enduring component of central sensitization, restricting the term "neuropathic pain" to those disorders with a primary etiology clearly related to the peripheral or CNS is prudent and consistent with clinical practice. 243 PMID- 16351031 AU - Rubin JJ TI - Psychosomatic pain: new insights & management strategies.

Jrubin352@aol.com AB - At least 40 to 60 percent of women and at least 20 percent of men with chronic pain disorders report a history of being abused during childhood and/or adulthood. This incidence of abuse is two to four times higher than in the general population. Patients with more severe or frequent abuse, usually during childhood and worse if sexual in nature. often develop specific syndromes or combinations of syndromes. These syndromes include posttraumatic stress disorder, fibromyalgia, and other conditions characterized by repression, somatization, and increased utilization of medical care. Psychosomatic symptoms and dysfunctional behaviors may emerge as these patients seek attention and validation of their suffering, while paradoxically repressing painful memories of trauma. Behavioral observations and key features of the physical examination may greatly help the clinician identify both the presence and severity of psychosomatic disease. In addition, it is very interesting that various studies document physiologic changes in the brains of patients with a history of abuse and in patients with a diagnosis of fibromyalgia. These studies suggest that abuse may physiologically and developmentally increase a person's susceptibility to pain and that some organic changes may be associated with psychogenic disease. Diagnosis and treatment of even the most challenging patients with chronic pain is much more effective if it includes (a) careful inquiry about any history of past or present abuse or other severe trauma, (b) empathy and constructive validation of disease and suffering, (c) recognition of dysfunctional pain behaviors and personality traits, (d) documentation of nonanatomic as well as anatomic features on examination, (e) multidisciplinary treatments including psychotherapy whenever indicated, and (f) noninvasive procedures and alternatives to potentially habit-forming medications whenever possible and appropriate. Furthermore, it has been shown that helping patients gain insight about the relationship between abuse and their current symptoms leads to decreased health care utilization. Practical guidelines are provided for identifying psychopathology, communicating effectively, and achieving better treatment outcomes for these unfortunate patients. 244 PMID- 15889304 AU - Russell AS, Hui BK TI - The use of PRIME-MD questionnaire in a rheumatology clinic.

IN - 562 Heritage Med Research Centre, U o Alberta Hosp, Edmonton, Alberta, Canada T6G 2S2. asr@ualberta.ca AB - OBJECTIVE: To determine whether the Primary Care Evaluation of Mental Disorders 1-page Brief Patient Health Questionnaire (PRIME-MD 1-page PHQ) can serve as: (1) a diagnostic test for fibromyalgia syndrome (FM), or (2) a questionnaire through which internists can be alerted to otherwise hidden mental disorders in patients attending internal medicine clinics. METHOD: Two hundred and thirteen consecutive patients attending a rheumatology clinic were given the PRIME-MD 1-page PHQ and seen by a rheumatologist who was blind to the PRIME-MD diagnosis. RESULTS: The PRIME-MD 1-page PHQ pointed to Major Depressive Disorder in 33.3% of FM patients, Other Depressive Disorder in 33.3% of FM patients, and Panic Disorder in 22.2% of FM patients (all of whom also had Major Depressive Disorder), as compared to 13.1, 13.1, and 3.0% respectively in patients with other rheumatic disorders. However, when used as a diagnostic test for FM, the PRIME-MD 1-page PHQ did not have adequate diagnostic value. When all the PRIME-MD 1-page PHQ diagnoses were compiled, however, a trend was observed. Compared to the rates of mental disorders in both the normal population and in primary care practices, the rates found in this rheumatology clinic were higher. CONCLUSIONS: The PRIME-MD 1-page PHQ is not an adequate diagnostic test for FM. Because FM is primarily a somatization disorder that draws its symptoms from other current diseases, it may in fact be impossible to diagnose FM based on specific symptoms alone. However, the PRIME-MD 1-page PHQ proved to be a useful diagnostic tool in a rheumatology clinic. It helped to alert the physician to the possibility of an elevated frequency of mental disorders that would otherwise have gone unnoticed and untreated. 245 PMID- 16393769 AU - Ruster M, Franke S, Spath M, Pongratz DE, Stein G, Hein GE TI - Detection of elevated N epsilon-carboxymethyllysine levels in muscular tissue & in serum of pts w FM.

Michael.Ruester@med.uni-jena.de AB - OBJECTIVES: To compare levels of the advanced glycation end product (AGE) N(epsilon)-carboxymethyllysine (CML) present in the muscle tissue and in the serum of patients with fibromyalgia (FM) vs. healthy controls. METHODS: The serum levels of CML were measured in 41 patients with FM and 81 healthy controls. The presence of CML, nuclear factor kappa B (NF-kappaB), the AGE receptor (RAGE), collagen types I, II, VI, and CD68-positive monocytes/macrophages in muscle tissue of 14 patients with FM was investigated by immunohistochemistry. RESULTS: Patients with FM showed significantly increased serum levels of CML in comparison to healthy controls. The immunohistochemical investigation revealed a stronger staining for CML and NF-kappaB and more CD68-positive monocytes/macrophages in the muscle of FM patients. The collagens and CML were co-localized, suggesting that the AGE modifications were related to collagen. RAGE was absent in controls but a faint and patchy staining was seen in FM. CONCLUSIONS: In the interstitial connective tissue of fibromyalgic muscles we found a more intensive staining of the AGE CML, activated NF-kappaB, and also higher CML levels in the serum of these patients compared to the controls. RAGE was only present in FM muscle. AGE modification of proteins causes reduced solubility and high resistance to proteolytic digestion of the altered proteins (e.g. AGE-modified collagens). AGEs can stimulate different types of cells by activation of the transcription factor NF-kappaB, mediated by specific receptors of AGEs (e.g. RAGE) on the cell surface. Both mechanisms may contribute to the development, perpetuation, and spreading of pain characteristic in FM patients. 246 PMID- 16215337 AU - Rustoen T, Wahl AK, Hanestad BR, Lerdal A, Paul S, Miaskowski C TI - Age & the experience of chr pain: differences in health & quality of life among younger, middle-aged, & older adults.

IN - Faculty o Nursing, Oslo U Coll, Oslo, Norway. tone.rustoen@su.hio.no AB - OBJECTIVES: To describe age differences in chronic pain and to evaluate for differences in demographic and health-related variables among younger (18-39 years), middle-aged (40-59 years), and older adults (60-81 years) who reported chronic pain. METHODS: A total of 4000 Norwegian citizens were mailed a questionnaire that measured pain, quality of life, mood, and demographic and health-related variables. RESULTS: Of the total sample (n = 1912), 19.2% of the younger age group, 27.5% of the middle-aged group, and 31.2% of the older group reported chronic pain (ie, >3 months duration). A total of 58.9% of the participants in chronic pain reported having a chronic disease, with the most common being musculoskeletal problems, chronic pain disorder, and osteoarthritis. Participants in the older age group reported pain of longer duration and more comorbidities and received pain treatment more often. They had higher total quality of life scores, were more satisfied with their material comforts and social life, and reported better mood. The middle-aged group reported the largest number of pain locations, reported having fibromyalgia more frequently, and reported that the cause of their pain was not known. They were less satisfied with their social life than the older age group. The younger age group reported the highest rates of injury and accidents as the cause of their pain, and almost 43% of this age group was not receiving any treatment of their chronic pain. CONCLUSION: This study found that the prevalence rates for chronic pain do vary with age and that the middle-aged group may be a high-risk group of patients with chronic pain. 247 PMID- 16396700 AU - Salaffi F, De Angelis R, Grassi W TI - Prevalence of musculoskeletal conditions in an Italian population sample: results of a regional community-based study.

IN - Dipartimento di Patologia Molecolare e Terapie Innovative, Cattedra di Reumatologia, Universita Politecnica delle Marche, Italy. fsalaff@tin.it AB - OBJECTIVE: The objective of the MAPPING study was to estimate the prevalence of musculoskeletal conditions in an Italian population sample. METHODS: Questionnaires were sent to a random sample of 3664 individuals aged 18 years and over, stratified for age and gender, selected from the practice lists of 16 general practices. Trained rheumatologists carried out structured visits in which subjects were asked about musculoskeletal symptoms and socio-demographic characteristics, and underwent a standardized physical examination. Cases were defined by previously validated criteria. RESULTS: A total of 2155 subjects participated in the study (response rate 58.8%). The overall prevalence of musculoskeletal conditions in the general adult population was 26.7% (95% CI 25.4-28.5), being significantly higher among women than men (p < 0.0001). Disease prevalence increased significantly with age (p < 0.0001). The most common disease group was symptomatic peripheral osteoarthritis (SPOA), with a prevalence of 8.95% (95% CI 6.81-10.7), followed by soft tissue disorders--STD (8.81%; 95% CI 7.16-10.29), low back pain--LBP (5.91%; 95% CI 4.89-6.89), and inflammatory rheumatic disease--IRD (3.06%; 95% CI 2.38-3.93). The estimated rates of disease prevalence were as follows: rheumatoid arthritis: 0.46% (95% CI 0.33-0.59); psoriatic arthritis: 0.42% (95% CI 0.31-0.61); ankylosing spondylitis: 0.37% (95% CI 0.23-0.49); polymyalgia rheumatica: 0.37% (95% CI 0.29-0.44); undifferentiated connective tissue disease: 0.14% (95% CI 0.09-0.21); crystal arthropathies, including gout 0.46% (95% CI 0.34-0.57) and chondrocalcinosis: 0.42% (95% CI 0.33-0.58); symptomatic knee osteoarthritis (OA): 5.39% (95% CI 3.41-7.99); hip-OA: 1.61% (95% CI 1.39-1.87); hand-OA: 1.95 (95% CI 1.22-2.48); fibromyalgia: 2.22% (95% CI 1.36-3.19); shoulder tendinitis/adhesive capsulitis: 3.06% (95% CI 2.11-4.09); carpal tunnel syndrome: 1.90% (95% CI 1.06-2.29), localized regional pain syndromes of the neck: 0.88% (95% CI 0.561.29), and lateral epicondylitis 0.74% (95% CI 0.47-1.33). CONCLUSIONS: The MAPPING study indicates that musculoskeletal conditions are common in the general adult population of Italy. These data are useful in planning the provision of healthcare. 248 PMID- 16056199 AU - Salek AK, Khan MM, Ahmed SM, Rashid MI, Emran MA, Mamun MA TI - Effect of aerobic exercise on pts w primary FM syndrome. SO - Mymensingh Med J. 2005 Jul;14(2):141-4. IN - D o Physical Med & Rehabilitation, Bangabandhu Sheikh Mujib Med U. akmsalek@bdonline.com AB - Sixty eight adult patients of fibromyalgia were included in this prospective study from the Outpatient Department of Physical Medicine and Rehabilitation of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka during the period of January 2003 to June 2003. Study samples were assigned into two treatment groups: Group A (n = 38) with exercise by static bicycle and aerobic walking in addition to tricyclic antidepressant and analgesic and Group B (n = 30) was non exercise group, treated with tricyclic antidepressant and analgesic only. The total duration of treatment was 16 weeks. Pre-treatment (week 0) and post treatment (week 16) evaluation was performed in both groups. Evaluation parameters included pain grade, number of trigger points, occurrence of arousal at night, frequency of micturition and global evaluation by the physician. After 16 weeks, mean improvement of exercise group and non exercise group was 48% and 39% respectively but this difference was not statistically significant. Therefore, from this study it was observed that aerobic exercise showed no significant benefit to fibromyalgia patients. 249 PMID- 16139178 AU - Sandberg M, Larsson B, Lindberg LG, Gerdle B TI - Different patterns of blood flow response in the trapezius muscle following needle stimulation (acupuncture) between healthy subjects & pts w FM & work-related trapezius myalgia.

IN - D o Rehabilitation Med, INR, Faculty o Health Sciences, SE-581 85 Linkoping, Sweden. margareta.sandberg@lio.se AB - Needle stimulation (acupuncture) has recently been shown to increase blood flow in the tibialis anterior muscle and overlying skin in healthy subjects (HS) and patients with fibromyalgia (FM). The aim of the present study was to examine the effect of needle stimulation on local blood flow in the trapezius muscle and overlying skin in HS and two groups of patients suffering from chronic pain in the trapezius muscle, i.e., FM and work-related trapezius myalgia (TM) patients. Two modes of needling, deep muscle stimulation (Deep) and subcutaneous needle insertion (SC), were performed at the upper part of the shoulder and blood flow was monitored for 60 min post-stimulation. Blood flow changes were measured non-invasively by using a new application of photoplethysmography. Increased blood flow in the trapezius muscle and overlying skin was found in all three groups following both Deep and SC. In HS, Deep was superior to SC in increasing skin and muscle blood flow, whereas in FM, SC was as effective as, or even more effective, than Deep. In the severely affected TM patients, no differences were found between the stimuli, and generally, a lesser blood flow response to the stimuli was found. At Deep, the muscle blood flow increase was significantly larger in HS, compared to the two patient groups. Positive correlations were found between muscle blood flow at Deep and pressure pain threshold in the trapezius muscle, neck movement and pain experienced at the stimulation, and negative correlations were found with spontaneous pain-related variables, symptom duration and age, pointing to less favorable results with worsening of symptoms, and to the importance of nociceptor activation in blood flow increase. It was hypothesized that the different patterns of muscle blood flow response to the needling may mirror a state of increased sympathetic activity and a generalized hypersensitivity in the patients. The intensity of stimulation should be taken into consideration when applying local needle stimulation (acupuncture) in order to increase the trapezius muscle blood flow in chronic pain conditions. 250 PMID- 16000677 AU - Sayar K, Barsky AJ, Gulec H TI - Does somatosensory amplification decrease w antidepressant Rx? SO - Psychosomatics. 2005 Jul-Aug;46(4):340-4. IN - Bakirkoy Mental Health Training & Research Hosp, Istanbul, Turkey. kemalsayar@hotmail.com AB - Somatosensory amplification refers to a tendency to experience somatic and visceral sensations as unusually intense, noxious, and disturbing. The authors wanted to determine whether somatosensory amplification is a stable construct or whether it might change with antidepressant therapy. Fifteen patients with fibromyalgia and 17 patients with major depressive disorder received antidepressant treatment and were assessed after 6 and 12 weeks of treatment. Amplification scores responded to antidepressant treatment in patients with major depression but not in patients with fibromyalgia, despite a decrease in the levels of depression in both groups. When change in depression and anxiety scores was partialled out from change in somatosensory amplification scores, the amplification scores did not change significantly in either the depressed or the fibromyalgia groups. Given the small numbers and the marginal significance of the results, the authors are unable to say definitely just how independent of depression somatosensory amplification is. Whether somatosensory amplification is a measure of depression per se should be tested in a more definitive and larger future study. 251 PMID- 15736726 AU - Schaefer KM TI - The lived experience of FM in African American women.

Two agreed to second interviews, for a total of 12 interviews for data analysis. Data analysis revealed the following themes: (a) managing the symptoms, (b) becoming a self-advocate, (c) medications camouflage the pain, (d) coming to grips with the illness means making changes, (e) being accused of "taking a free ride" angers them, (f) support comes from self and spiritual connections, and (g) a certain amount of secrecy makes it easier to live with the illness. Recommendations focus on using a holistic approach to help African American women achieve or maintain their integrity. 252 PMID- 15947513 AU - Schleicher H, Alonso C, Shirtcliff EA, Muller D, Loevinger BL, Coe CL TI - In the face of pain: the relationship between psychological well-being & disability in women w FM.

IN - D o Psychology, U o Wisconsin-Madison, Madison, Wisc. 59812-1584, USA. hollys@uwalumni.com AB - BACKGROUND: Few studies have examined the potentially beneficial role of positive psychological functioning in individuals with chronic pain. This study examined the relationship of psychological well-being (PWB) to pain and disability in women with fibromyalgia (FM) as compared to women with rheumatoid arthritis (RA) and healthy controls (HC). We targeted several domains of PWB that have been associated with health, and also tested whether PWB was related to the women's social network. METHODS: PWB, pain, and disability were assessed in 125 women (57 with FM, 20 with RA, and 48 HC) on two occasions. RESULTS: Women with FM reported lower overall PWB than did RA and HC women. Further, greater PWB was associated with less disability and fatigue, but not pain in women with FM. Self-acceptance, environmental mastery, purpose in life, and positive relations with others emerged as four important constructs in the association between PWB and disability. In addition, PWB mediated the relationship between social network size and disability. CONCLUSIONS: This assessment of PWB provides insight into those psychological domains that should be emphasized in treatments aimed at reducing the disabling aspects of FM. 253 PMID- 15992573 AU - Schmaling KB, Fiedelak JI, Bader J, Buchwald D TI - A longitudinal study of physical activity & body mass index among persons w unexplained chr fatigue.

IN - College o Health & Human Services, U o North Carolina, Charlotte, NC 28223, USA. kbschmal@email.uncc.edu AB - OBJECTIVE AND METHODS: A cohort of 100 patients with unexplained chronic fatigue (CF) was assessed longitudinally for 1.5 years to determine if physical activity (kcal expended), exercise capacity (VO(2)max), perceived exertion, and body mass index (BMI) changed over time and were associated with changes in CF-related clinical status. RESULTS: BMI increased significantly over time but did not predict changes in clinical status. Increasing energy expenditure was associated with increasing vitality and decreasing CF symptom severity over time, and decreasing perceived exertion was associated with increasing physical functioning. However, increasing perceived exertion was also associated with increasing CF symptoms. CONCLUSIONS: These data do not support models that posit associations between CF and deconditioning. 254 PMID- 15813608 AU - Segal TY, Hindmarsh PC, Viner RM TI - Disturbed adrenal function in adolescents w CFS. SO - J Pediatr Endocrinol Metab. 2005 Mar;18(3):295-301. IN - U Coll London Hospitals, UK. AB - OBJECTIVE: To investigate adrenal function in children and adolescents with chronic fatigue syndrome (CFS) compared with age-matched controls. METHODS: Case-control study of low dose (500 ng/m2) synacthen tests (LDST) in 23 adolescents with CFS and 17 age-matched controls. Serum cortisol concentrations were measured at 5-min intervals from 10 to 45 minutes. Peak serum cortisol concentration, time to peak, rise in cortisol and area under the curve (AUC) were derived. RESULTS: Patients with CFS had significantly lower mean cortisol levels during the LDST (p <0.001), lower peak cortisol (p <0.025), reduced cortisol AUC (p <0.005) and longer time to peak cortisol (p <0.05). Abnormalities were seen in both sexes but were more pronounced in females. Unstimulated adrenal androgen and 17-hydroxyprogesterone concentrations were normal. CONCLUSIONS: Adolescents with CFS have subtle alterations in adrenal function suggesting a reduction in central stimulation of the adrenal glands. The more pronounced effects in females may reflect differential central effects of stress on hypothalamic-pituitary-adrenal axis regulation between the sexes. 255 PMID- 16322133 AU - Seng JS, Graham-Bermann SA, Clark MK, McCarthy AM, Ronis DL TI - Posttraumatic stress disorder & physical comorbidity among female children & adolescents: results from service-use data.

IN - Institute for Research on Women & Gender, U o Michigan, Ann Arbor, MI 48109-1290, USA. jseng@umich.edu AB - OBJECTIVE: In adults, posttraumatic stress disorder (PTSD) is associated with adverse health outcomes and high medical utilization and cost. PTSD is twice as common in women and is associated with increased risk for a range of diseases, chronic conditions, and reproductive-health problems. Little is known about the health effects of PTSD in children. The purpose of this study was to explore patterns of physical comorbidity in female children and adolescents with PTSD by using population data. METHODS: This study was a cross-sectional, descriptive epidemiologic case-control analysis of a Midwestern state's Medicaid eligibility and paid-claims data for girls (0-8 years old) and teens (9-17 years old). Data were from 1994-1997. All those with the PTSD diagnostic code were compared with randomly selected controls in relation to 3 sets of outcomes: (1) International Classification of Diseases, Ninth Revision (ICD-9) categories of disease; (2) chronic conditions previously associated with sexual trauma and PTSD in women; and (3) reproductive-health problems. Analyses included bivariate odds ratios (OR) and logistic-regression models that control for the extent of insurance coverage and the independent associations of victimization and psychiatric comorbidity with the 3 sets of outcomes. The mental health covariate was categorical to allow consideration of a range of severity. There were 4 categories for the young girls: neither PTSD nor depression, PTSD without depression, depression without PTSD, and PTSD + depression. For the adolescent analysis, a fifth category reflecting a "complex PTSD" was added, defined as having PTSD complicated by a dissociative disorder or borderline personality disorder diagnosis. RESULTS: There were 647 girls and 1025 adolescents with the PTSD diagnosis. Overall, PTSD was associated with adverse health outcomes in both age strata. Victimization was sometimes independently associated with adverse health outcomes, but PTSD often was a mediator, especially in the adolescent age stratum. The importance of PTSD diagnosis as a predictor of the ICD-9 categories of disease or chronic conditions seemed to increase with age. In the younger age stratum, the increased bivariate ORs of significant associations with PTSD ranged from 1.4 for digestive disorders to 3.4 for circulatory disorders. Among younger girls, PTSD diagnosis was associated with significantly greater bivariate odds for 9 of the 12 ICD-9 categories of disease but not for neoplasms, blood disorders, or respiratory disorders and with threefold increased odds for chronic fatigue. They also had 1.8 times greater odds for sexually transmitted infections, some of which could be from congenital transmission in this age group, which includes infants. In the multivariate models for the young girls, the mental health variable seemed to mediate the relationship between victimization and increased odds of infectious and parasitic diseases, endocrine/metabolic/immune disorders, circulatory diseases, skin and cutaneous tissue disorders, and having any 1 of the 5 chronic conditions. The mental health categories that were significantly associated with health outcomes varied across the conditions. There were no health outcomes in which the depression-without-PTSD category was the only one significantly associated with the outcome condition. Circulatory and musculoskeletal disorders were significantly associated with all 3 of the mental health categories. Having any 1 of the 5 chronic conditions was significantly associated only with simple PTSD (PTSD without depression). Genitourinary disorders and signs/symptoms/ill-defined conditions were significantly associated with both simple and comorbid PTSD. PTSD with comorbid depression, the most severe of the mental health categories in this younger age group, was the only category associated with the endocrine/metabolic/immune disorders and skin disorders outcomes. In the adolescent age stratum, the bivariate ORs significantly associated with PTSD ranged from 2.1 for blood disorders to 5.2 for irritable bowel syndrome. Adolescents with PTSD were nearly twice as likely to have a sexually transmitted infection and 60% more likely to have cervical dysplasia. However, their rate of pregnancy was lower (23% vs 31%), a one-fourth decreased odds. In the adolescent group, only 4 outcomes (nervous system/sense organ, digestive, and genitourinary disorders and signs/symptoms/ill-defined conditions) remained statistically significantly associated with victimization after the mental health variable was added, suggesting an additive model of risk for these outcomes but a mediating role for PTSD in relation to the majority of the health outcomes. Among the adolescent girls, the range of ORs for the ICD-9 and chronic-condition diagnoses generally increased across the categories of the mental health variable in a dose-response pattern. Compared with adolescents with neither PTSD nor depression, those with PTSD without depression had statistically significant ORs from 1.5 to 3.6. Those with depression without PTSD had statistically significant ORs from 1.9 to 4.4. The significant ORs for those with PTSD comorbid with depression were from 2.3 to 6.6, and those in the complex-PTSD category had significant ORs of between 2.5 and 14.9. Only blood disorders seemed to be more strongly associated with depression alone than with the comorbid and complex forms of PTSD. The simple-PTSD category was not significantly associated with blood disorders, chronic pelvic pain, fibromyalgia, or dysmenorrhea. Depression without PTSD was not significantly associated with chronic pelvic pain or fibromyalgia. Fibromyalgia was only significantly associated with complex PTSD. CONCLUSIONS: In young girls who receive Medicaid benefits, PTSD was associated with increased odds of a range of adverse health conditions. The pattern and odds of physical comorbidity among adolescent recipients with PTSD was nearly as extensive as that seen in adult women. Overall, the pattern observed suggests that objective disease states (eg, circulatory problems, infections) may be associated with PTSD to an extent nearly as great as that of PTSD with more subjective somatic experience of loss of wellness. Using the concepts of allostatic load and allostatic support, professionals who work with children and adolescents may be able to decrease the toll that traumatic stress takes on health even if available interventions can only be thought of as supportive and fall short of completely preventing trauma exposure or completely healing posttraumatic stress. Clinical research to extend these exploratory findings is warranted. 256 PMID- 16253617 AU - Shapiro JR, Anderson DA, Danoff-Burg S TI - A pilot study of the effects of behavioral weight loss Rx on FM Sx.

AB - OBJECTIVE: Previous studies have found a relation between weight loss and pain severity in various chronic pain populations. However, there has been little research examining the relation between body mass index (BMI) and fibromyalgia syndrome (FMS). The purpose of this pilot study was to investigate the relationship between BMI and FMS symptoms and to determine if FMS symptoms would decrease following weight loss. METHODS: Overweight and obese women participated in a 20-week behavioral weight loss treatment. RESULTS: Participants, on average, lost 9.2 lbs (4.4% of their initial weight), and there were significant pre-postimprovements on several outcome measures. Although weight was not significantly related to pain at baseline, weight loss significantly predicted a reduction in FMS, pain interference, body satisfaction, and quality of life (QOL). CONCLUSION: Findings suggest that behavioral weight loss treatment could be included in the treatment for overweight/obese women with FMS. 257 PMID- 16230991 AU - Shephard RJ TI - CFS.

A review of etiology and mechanisms underlying functional disturbances is undertaken to provide a valid basis for therapeutic options. The review focuses on CFS as characterized by standard diagnostic criteria, building on previous reviews through use of articles identified by Medline search. Overtraining, a negative energy balance, excessive physical or environmental stress, disorders of personality and affect, dysfunction of the hypophyseal-pituitary adrenal axis, hormonal imbalance, nutritional deficits, immune suppression or activation and chronic infection have all been proposed as factors precipitating CFS, but none of these precipitants are observed consistently. Impairments of peak aerobic power and muscle strength, together with many functional disturbances, seem related to patient- or physician-imposed inactivity. Once CFS is established, treatment should aim at breaking the vicious cycle of effort avoidance, deterioration in physical condition and increasing fatigue through a combination of psychotherapy, general encouragement and a progressive exercise regimen. 258 PMID- 15844841 AU - Shin YI, Lee MS TI - Qi therapy (external qigong) for CFS: case studies.

AB - BACKGROUND: Fatigue is reported by many adults at the moment of diagnosis of coeliac disease and during follow-up. AIM: To evaluate the prevalence, characteristics and associations of fatigue in adult coeliac disease patients. METHODS: The investigated sample comprised adults from Campania, Italy. A total of 130 coeliac disease patients were consecutively recruited in both treated (59 on gluten-free diet) and untreated conditions (71 on normal diet). The control group was made up of 80 healthy controls. Coeliac disease patients and healthy controls underwent laboratory tests, a set of questionnaires for studying fatigue: visual analogue scale for fatigue, chronic fatigue syndrome questionnaire, fatigue severity scale and a modified version of the Zung self-rating depression scale. RESULTS: Coeliac disease patients showed a significantly lower body mass index than controls (P = 0.0001), lower serum iron (P = 0.04). The entire cohort of coeliac disease patients reported greater modified version of the Zung self-rating depression scale score (P = 0.001), greater visual analogue scale for fatigue score (P = 0.0001) and greater chronic fatigue syndrome questionnaire score (P = 0.0001) compared with healthy controls. Coeliac disease patients on a gluten-free diet had a significantly higher modified version of the Zung self-rating depression scale score than coeliacs on a normal diet (P = 0.001). The prevalence of pathological modified version of the Zung self-rating depression scale score was 17% in all coeliac disease patients and 0% in healthy controls. A significant correlation was found between modified version of the Zung self-rating depression scale score and fatigue scale scores in coeliacs on a normal diet. Presence/absence of gastrointestinal symptoms did not show any significant correlation with modified version of the Zung self-rating depression scale score and fatigue scale scores. In coeliacs on a gluten-free diet, modified version of the Zung self-rating depression scale and fatigue scales scores did not significantly differ from coeliacs on a normal diet and were not related to dietetic compliance. CONCLUSION: In coeliacs, fatigue is a common finding, which ameliorates with the gluten-free diet and is strictly correlated to depression although coeliacs on a gluten-free diet showed more frequent and more severe depression symptoms than coeliacs on a normal diet. 260 PMID- 15895835 AU - Sipila K, Zitting P, Siira P, Niinimaa A, Raustia AM TI - Generalized pain & pain sensitivity in community subjects w facial pain: a case-control study.
