Abstract
OBJECTIVE Recent evidence suggests that a number of psychiatric and medical conditions may be members or candidate members of a larger family of conditions, which we have termed "affective spectrum disorder (ASD)." In order to facilitate further research into this concept, we drafted seven interview modules, using the format of the Structured Clinical Interview for DSM-III-R (SCID), designed to diagnose the following psychiatric and medical disorders: irritable bowel syndrome, narcolepsy, Tourette's disorder, migraine, fibromyalgia, chronic fatigue syndrome, and kleptomania. METHOD Published operational diagnostic criteria for these seven disorders were sought in the literature. Questions in SCID format were then drafted in accordance with these operational criteria. Draft modules were then sent to experts familiar with each of the disorders and suggestions and revisions from these experts incorporated into the final modules. RESULTS The complete supplemental interview is presented with this report. Preliminary experience with this interview in more than 100 patients tentatively suggests that it is reliable for diagnosing the disorders in question; however, a formal test-retest reliability assessment is still required. CONCLUSIONS It is hoped that this supplemental interview, used in conjunction with the SCID, will be helpful in further studies of the epidemiology, pathogenesis, and treatment of these possible forms of affective spectrum disorder.

Abstract
The symptom of chemical intolerance may occur in isolation, but often occurs in conjunction with other chronic symptoms such as pain, fatigue, memory disturbances, etc. This frequent clustering of symptoms in individuals has led to the definition of several chronic multisymptom syndromes, such as multiple chemical sensitivity, fibromyalgia, chronic fatigue syndrome, and Gulf War illnesses. The aggregate research into these syndromes has suggested some unifying mechanisms that contribute to symptomatology. Multiple lines of evidence suggest that there is aberrant function of numerous efferent neural pathways, such as the autonomic nervous system and hypothalamic-pituitary axes, in subsets of individuals with these conditions. There is perhaps the greatest evidence for abnormal sensory processing in these syndromes, with a low "unpleasantness threshold" for multiple types of sensory stimuli. Psychological and behavioral factors are known to play a significant role in initiating or perpetuating symptoms in some persons with these illnesses. In the field of pain research, the interrelationship between physiologic and psychologic factors in symptom expression has been well studied. Using both established and novel methodologies, studies have suggested that psychologic factors such as hypervigilance and expectancy are playing a relatively minor role in most individuals with fibromyalgia and that clear evidence exists of physiologic amplification of sensory stimuli. These studies need to be extended to more sensory tasks and to larger numbers of subjects with related conditions. It is of note, though, that existing data on this spectrum of illnesses would suggest that there may be greater psychologic contributions to symptomatology if an illness is defined in part by behavior (e.g., avoidance of chemical exposures) rather than on the basis of symptoms alone.

Abstract
BACKGROUND Primary fibromyalgia syndrome (PFS) is a chronic disorder commonly seen in rheumatological practice. The pathophysiological disturbances of this syndrome, which was defined by the American College of Rheumatology in 1990, are poorly understood. This study evaluated, in 30 patients, the hypothesis that PFS is a pain modulation disorder induced by deregulation of serotonin metabolism. OBJECTIVES To compare platelet [(3)H]imipramine binding sites and serotonin (5-HT) levels in plasma-rich platelets (PRP) of PFS patients with those of matched healthy controls and to compare the levels of biogenic amine metabolites in the cerebrospinal fluid (CSF) of PFS patients with those of matched controls. METHODS Platelet [(3)H]imipramine binding sites were defined by two criteria, B(max) for their density and K(d) for their affinity. PRP 5-HT and CSF metabolites of 5-HT (5-hydroxyindoleacetic acid, 5-HIAA), norepinephrine (3-methoxy, 4-hydroxy phenylglycol, MHPG) and dopamine (homovanillic acid, HVA) were assayed by reversed-phase high-performance liquid chromatography with coulometric detection. RESULTS [(3)H]Imipramine platelet binding was similar (P=0.43 for B(max) and P=0.30 for K(d)) in PFS patients (B(max)=901+/-83 fmol/mg protein, K(d)=0.682+/-0.046) and in matched controls (B(max)=1017+/-119 fmol/mg protein, K(d)=0.606+/-0.056). PRP 5-HT was significantly higher (P=0.0009) in PFS patients (955+/-101 ng/10(9) platelets) than in controls (633+/-50 ng/10(9) platelets). When adjusted for age, the levels of all CSF metabolites were lower in PFS patients. The CSF metabolite of norepinephrine (MHPG) was lower (P:=0.003) in PFS patients (8.33+/-0.33 ng/ml) than in matched controls (9.89+/-0.31 ng/ml) and 5-HIAA was lower (P=0.042) in PFS female patients (22.34+/-1.78 ng/ml) than in matched controls (25.75+/-1.75 ng/ml). For HVA in females, the difference between PFS patients (36.32+/-3.20 ng/ml) and matched controls (38.32+/-2.90 ng/ml) approached statistical significance (P=0.054). CONCLUSION Changes in metabolites of CSF biogenic amines appear to be partially correlated to age but remained diagnosis-dependent. High levels of PRP 5-HT in PFS patients were associated with low CSF 5-HIAA levels in female patients but were not accompanied by any change in serotonergic uptake as assessed by platelet [(3)H]imipramine binding sites. These findings do not allow us to confirm that serotonin metabolism is deregulated in PFS patients.

Abstract
A fibromialgia é uma patologia de alta prevalência na população geral, cujo tratamento é feito por meio de medicamentos como antiinflamatórios, antidepressivos e miorrelaxantes, que pode ser complementado por medidas físicas como relaxamento, alongamento e exercícios físicos. A observação de fibromialgia entre atletas constatada em exames de rotina, em especial naqueles que apresentavam lesões musculares de repetição, levou os autores a pesquisar, de maneira prospectiva, um grupo de atletas praticantes de ginástica olímpica e atletismo, nos quais puderam confirmar alta incidência desta síndrome. Como a fibromialgia predispõe ao aparecimento de lesões por contratura muscular, sugerem que ela possa atuar como um mecanismo de indução ao surgimento de lesões musculares de repetição. Ainda devido às semelhanças dos sintomas encontrados na síndrome do supertreinamento, síndrome da fadiga crônica e fibromialgia, propõem uma possível ligação entre estes quadros.

Abstract
The aims of the present study were to examine serotonergic markers, i.e. [3H]paroxetine binding characteristics and the availability of plasma tryptophan, the precursor of serotonin (5-HT), and the plasma concentrations of the branched chain amino acids (BCAAs), valine, leucine and isoleucine, in fibromyalgia. The [3H]paroxetine binding characteristics, B(max) and K(d) values, and tryptophan and the competing amino acids (CAA), known to compete for the same cerebral uptake mechanism (i.e. valine, leucine, isoleucine, phenylalanine and tyrosine), were determined in fibromyalgia patients and normal controls. There were no significant differences in the [3H]paroxetine binding characteristics (B(max) and K(d)) between fibromyalgia and control subjects. There were no significant differences in plasma tryptophan or the tryptophan/CAA ratio between fibromyalgia patients and normal controls. In the fibromyalgia patients, there were no significant correlations between [3H]paroxetine binding characteristics or the availability of tryptophan and myalgic or depressive symptoms. Patients with fibromyalgia had significantly lower plasma concentrations of the three BCAAs (valine, leucine and isoleucine) and phenylalanine than normal controls. It is hypothesized that the relative deficiency in the BCAAs may play a role in the pathophysiology of fibromyalgia, since the BCAAs supply energy to the muscle and regulate protein synthesis in the muscles. A supplemental trial with BCAAs in fibromyalgia appears to be justified.

Abstract
This study was done to review the literature concerning the influence of minor and major stress factors on onset and course of rheumatoid arthritis (RA), juvenile chronic arthritis (JCA), systemic lupus erythematosus (SLE), and fibromyalgia syndrome (FS). Major life events and chronic minor stress seem to be very important factors in JCA and are significantly associated with the onset of the disease. With respect to RA and FS, stress may be a provoking factor but the data in the literature are equivocal. However, during the course of the disease, minor stress aggravates SLE, FS, JCA, and RA. Patients with FS and RA may profit from psychological therapies. Optimistic and confronting coping strategies were found most frequently and perceived to be most effective. Very important for psychological function is the social background, especially the functioning of the family is of outstanding importance for clinical and psychological outcome.

Abstract
The effect of the selective serotonin reuptake inhibitor citalopram was studied in a randomized, double-blind, placebo-controlled, 4-month trial in patients with the fibromyalgia syndrome (FMS) who all fulfilled the American College of Rheumatology criteria. The citalopram doses varied between 20-40 mg daily. Forty female patients, 21 patients in the citalopram and 19 in the placebo group, participated. Assessment of pain, depressive symptoms and physical functioning were made using Visual Analogue Scales (VAS), the Montgomery Asberg Depression Rating Scale (MADRS) and the Fibrositis Impact Questionnaire (FIQ). In the global judgement of improvement, no significant changes were found between the citalopram and placebo groups as concerns pain or well-being, either in the Intention to Treat (ITT) analysis or in the completer analysis. However, among the completers, it was a tendency that more patients in the citalopram group (52.9%) were improved as compared to the placebo group (22.2%) concerning well-being. Furthermore, the results indicated that treatment with citalopram had a significant effect on pain on the VAS after 2 months of treatment compared to baseline. After 4 months, however, the effect had diminished. Measured with the FIQ, significant differences in the pain ratings were seen at the end of the trial. Significant effects on the depressive symptomatology measured by means of the MADRS were seen already after 1 month of treatment and were increasing further at the end of the trial, when a significant difference between the groups was also found.

Abstract
Twenty (20) people who had medically diagnosed fibromyalgia for two to 15+ years participated in and completed a 90-day evaluation to determine effects of collagen hydrolysat on symptoms of chronic fibromyalgia, with twelve reporting temporomandibular joint pain. Collagen hydrolysat is a food supplement that is available without prescription, with no known side effects. Participants were evaluated initially and then at 30-, 60-, and 90-day periods. Final results were obtained and comparisons made. The average pain complaint levels decreased significantly in an overall group average, and dramatically with some individuals. It was concluded that patients with fibromyalgia and concurrent temporomandibular joint problems may gain symptomatic improvement in their chronic symptoms by taking collagen hydrolysat.

Abstract
The aims of this study were: (1) to compare two groups of patients with chronic pain conditions (work-related muscular pain, mainly low back pain, and fibromyalgia) in general coping and pain-specific coping; (2) to examine the relationship between general and pain-specific coping and, (3) to examine the influence of state-trait anxiety on general and pain-specific coping. The sample included 80 individuals (range=19-70 years; mean=47; SD=9.9), who were patients at two pain management clinics for examination of their physical and psychosocial health conditions and consideration on disability pension. The patients were asked to respond to theStrategies to Handle Stress Questionnaire, theCoping Strategies Questionnaireand theState-Trait Anxiety Inventory. Patients with fibromyalgia scored significantly higher on T-anxiety and adopted <<problem-solving>> (p<0.01) and <<catharsis>> (p<0.05) less often and <<religion>> more often (p<0.01) than patients with work-related muscular pain in coping with stressful situations in general. No differences were revealed in pain-related coping between the groups. T-anxiety was positively correlated to pain-related <<catastrophizing>> (p<0.001) and negatively to abilities to control and reduce pain (p<0.05 andp<0.01, respectively). The correlation between general and pain-specific coping was weak to moderate. In conclusion, patients with fibromyalgia scored significantly higher on trait-anxiety and seem to interpret stressful situations as more threatening than patients with work-related muscular pain. Anxiety seems to be of central importance for coping with chronic pain. Anxiety-prone patients with fibromyalgia might benefit from psychological support in the process of coping with pain.

Abstract
Fibromyalgia is a common musculoskeletal pain disorder associated with mood disorders. Antidepressants, particularly tricyclics, are commonly recommended treatments. Randomized, controlled trials of antidepressants for treatment of fibromyalgia were reviewed by methodology, results, and potential predictors of response. Twenty-one controlled trials, 16 involving tricyclic agents, were identified; 9 of these 16 studies were suitable for meta-analysis. Effect sizes were calculated for measurements of physician and patient overall assessment, pain, stiffness, tenderness, fatigue, and sleep quality. Compared with placebo, tricyclic agents were associated with effect sizes that were substantially larger than zero for all measurements. The largest improvement was associated with measures of sleep quality; the most modest improvement was found in measures of stiffness and tenderness. Further studies are needed utilizing randomized, double-blind, placebo-controlled, parallel designs with antidepressants administered at therapeutic dose ranges, using standardized criteria for fibromyalgia and systematically assessed for co-occurring psychiatric illness.

Abstract
BACKGROUND Fibromyalgia is not an uncommon condition. Because its cause has yet to be identified. treatment of the condition has been empirical; frequently, outcomes are unsatisfactory. Some patients with fibromyalgia were observed to have high hair calcium and magnesium levels compared with healthy subjects. Because of this and because supplementing calcium with magnesium to fibromyalgia subjects reduced the number of tender points detected by digital palpation, it is worth investigating if patients with fibromyalgia have significantly higher hair calcium and magnesium levels than their healthy counterparts. OBJECTIVES To determine the degree of difference between the hair calcium and magnesium levels in patients with fibromyalgia and in healthy subjects. METHODS The study was retrospective and of paired design. Twelve patients who had hair analysis performed and met the criteria of fibromyalgia defined by American College of Rheumatology (1990) were selected consecutively from clinical files. These patients were then matched by age and sex to 12 healthy subjects selected consecutively from the same patient files who had hair analysis performed for checkup purposes. Nonparametric Wilcoxon rank sum tests were used to determine if the hair calcium and magnesium levels in patients with fibromyalgia were significantly higher than that of the control subjects. RESULTS Wilcoxon rank sum tests showed that patients with fibromyalgia had significantly higher calcium and magnesium levels than the control subjects at alpha = .025 and .05, respectively. CONCLUSION In the presence of high hair calcium and magnesium levels, calcium and magnesium supplements may be indicated as an adjunctive treatment of fibromyalgia.

Abstract
Patients whose symptoms include widespread, diffuse musculoskeletal pain are commonly referred for rheumatological evaluation, even when the underlying cause may lie out with the remit of rheumatology. A diagnosis of fibromyalgia may seem highly probable even from the referral letter, or after a few leading questions during the consultation. However, the lack of specificity of the many symptoms associated with widespread pain means that other diagnoses have to be considered. The history and examination must bear in mind alternative and concomitant musculoskeletal disorders, such as mild systemic lupus erythematosus, polyarticular osteoarthritis, rheumatoid arthritis, polymyalgia rheumatica, hypermobility syndromes and even osteomalacia. Non-rheumatological diseases may also have symptomatic similarities to fibromyalgia, including neoplastic and neurological diseases, hypothyroidism and other endocrine disorders, chronic infections, as well as a variety of psychiatric conditions. A rational approach to investigation will usually allow other diagnostic possibilities to be excluded without reinforcing the abnormal illness behaviour so common in chronic pain states.

Abstract
One hundred and twelve fibromyalgia syndrome (FMS) patients were randomized into one of four demographically similar groups (n = 28/group). Sequential primary FMS patient volunteers were to receive daily sublingual placebo or interferon-alpha (IFN-alpha) at 15, 50, or 150 IU. After a screening evaluation, analgesic or sedative hypnotic medications were withdrawn. Two weeks later, daily IFN-alpha or placebo was initiated with follow-up evaluations at 2-week intervals ending with week 6. One primary, three secondary, and seven tertiary variables were assessed. Study outcome was based on improvement in the tender point index (TPI). The TPI did not improve with any IFN-alpha dose. However, significant improvement was seen in morning stiffness and in physical function with the 50 IU IFN-alpha (p < 0.01). None of the other outcome means changed significantly and no adverse events were attributable to IFN-alpha therapy.

Abstract
A clinical study was designed to utilize flow cytometric immunophenotyping and chromium release from cultured tumor target cells to characterize peripheral blood mononuclear leukocyte (PBML) subpopulations and natural killer activity in healthy normal controls (n = 18) and in patients with fibromyalgia syndrome (FMS) at baseline (n = 124) and again after 6 weeks of treatment with low-doses of orally administered human interferon-alpha (IFN-alpha). Volunteer subjects discontinued all analgesic and sedative hypnotic medications for 2 weeks prior to the baseline phlebotomy. Laboratory measures included a complete blood count; a phenotypic analysis of PBML by flow cytometry; and in vitro natural killer (NK) cell activity. After baseline blood sample collection, the FMS patients were randomized to one of four parallel treatment groups (n = 28/group) to receive sublingual IFN-alpha (15 IU, 50 IU, 150 IU), or placebo every morning for 6 weeks. The tests were repeated at week 6 to evaluate treatment effects. At baseline, FMS patients exhibited fewer lymphocytes and more CD25+ T lymphocytes than did normal controls. By week 6, the main significant and consistent change was a decrease in the HLA-DR+ CD4+ subpopulation in the 15 IU and 150 IU treatment groups. These data do not support an immunologically dysfunctional PBML phenotype among patients with FMS as has been observed in the chronic fatigue syndrome.

Abstract
Fibromyalgia is a chronic, painful musculoskeletal disorder characterized by widespread pain, pressure hyperalgesia, morning stiffness and by an increased incidence of depressive symptoms. The etiology, however, has remained elusive. The aim of the present study was to examine the inflammatory response system (IRS) in fibromyalgia. Serum interleukin-6 (IL-6), soluble IL-6 receptor (sIL-6R), sgp130, sIL-1R antagonist (IL-1RA) and sCD8 were determined in 33 healthy volunteers and in 21 fibromyalgia patients, classified according to the American College of Rheumatology criteria. Severity of illness was measured with several pain scales, dolorimetry and the Hamilton Depression Rating Scale (HDRS). Serum sgp130 was significantly higher and serum sCD8 significantly lower in fibromyalgia patients than in healthy volunteers. Serum sIL-6R and sIL-1RA were significantly higher in fibromyalgia patients with an increased HDRS score (> or = 16) than in normal volunteers and fibromyalgia patients with a HDRS score < 16. In fibromyalgia patients, an important part of the variance in sCD8 (50.3%) and IL-1RA (19.3%) could be explained by the HDRS score; 74.3% of the variance in sIL-6R was explained by the combined effects of pain symptoms and the HDRS score; and 25.9% of the variance in serum sgp130 was explained by stiffness. The results support the contention that pain and stiffness in fibromyalgia may be accompanied by a suppression of some aspects of the IRS and that the presence of clinically significant depressive symptoms in fibromyalgia is associated with some signs of IRS activation.

Abstract
The authors conducted an investigation in four tertiary-care centers to determine if psychiatric comorbidity and psychological variables were predictive of functional impairment in patients with fibromyalgia syndrome (FMS). Seventy-three individuals were administered the Structured Clinical Interview for DSM-III-R, the Rand 36-item Health Survey (SF-36), and multiple self-report measures. The patients with FMS were found to have a high lifetime and current prevalence of major depression and panic disorder. The most common disorders were major depression (lifetime [L] = 68%, current [C] = 22%); dysthymia (10% [C only]); panic disorder (L = 16%, C = 7%); and simple phobia (L = 16%, C = 12%). The self-report scales revealed significant elevations in depression, anxiety, neuroticism, and hypochondriasis. Functional impairment on all measures of the SF-36 was severe (e.g., physical functioning = 45.5 and role limitations due to physical problems = 20.0). Stepwise multiple-regression analysis revealed that current anxiety was the only variable that predicted a significant proportion of the variance (29%) in SF-36 physical functioning. Thus, in this multicenter study, the persons with FMS exhibited marked functional impairment, high levels of some lifetime and current psychiatric disorders, and significant current psychological distress. Current anxiety level appears to be an important correlate of functional impairment in individuals with FMS.

Abstract
The higher prevalence of depression in women is coupled with a higher prevalence of pain complaints. Growing evidence suggests that the comorbidity of these conditions is also proportionately higher in women than men. This paper critically reviews the empirical findings relating to gender differences in comorbid pain and depression as well as findings in support of hypothesized etiologic factors that could explain why women may be more susceptible than men to comorbidity. The empirical evidence for biogenic, psychogenic, and sociogenic explanatory models is presented, and an integration of these models is proposed as a guideline to both research and clinical practice. In conclusion, it is argued that gender-differentiated treatment strategies are not clinically indicated at this time.

Abstract
OBJECTIVE To determine whether history of severe, long-term, premorbid, psychological stress is associated with increased incidence of chronic physical symptoms in presumed Lyme disease patients. METHODS Fifty-seven patients presenting at Lyme Disease Clinic of Long Island Jewish-Hillside Medical Center were studied for presenting symptoms, presence or absence of Lyme disease, and past history of psychological trauma. They were restudied 1 to 1.5 years later for presence or absence of physical symptoms. Statistical analyses compared symptom course for patients with and without Lyme disease, antibiotic and nonantibiotic treatments, and past history of psychological trauma. RESULTS There was correlation between history of past traumatic psychological events and chronicity of physical symptoms whether or not the patient had presumed Lyme disease or had received antibiotic treatment. CONCLUSION Traumatic psychological experiences predating onset of Lyme disease symptoms may play an important etiologic role in the chronicity of these symptoms.

Abstract
There is now firm evidence that major depression is accompanied by increased baseline activity of the hypothalamic-pituitary-adrenal (HPA) axis, as assessed by means of 24-h urinary cortisol (UC) excretion. Recently, there were some reports that fibromyalgia and post-traumatic stress disorder (PTSD), two disorders which show a significant amplitude of depressive symptoms, are associated with changes in the baseline activity of the HPA axis, such as low 24-h UC excretion. The aim of the present study was to examine 24-h UC excretion in fibromyalgia and PTSD patients compared to normal controls and patients with major depression. In the three patient groups, severity of depressive symptoms was measured by means of the Hamilton Depression Rating Scale (HDRS) score. Severity of fibromyalgia was measured using a dolorimetrically obtained myalgic score, and severity of PTSD was assessed by means of factor analytical scores computed on the items of the Composite International Diagnostic Interview (CIDI), PTSD Module. Patients with PTSD and major depression had significantly higher 24-h UC excretion than normal controls and fibromyalgia patients. At a threshold value of > or = 240 micrograms/24 h, 80% of PTSD patients and 80% of depressed patients had increased 24 h UC excretion with a specificity of 100%. There were no significant differences in 24-h UC excretion either between fibromyalgia patients and normal controls, or between patients with major depression and PTSD patients. In the three patient groups, no significant correlations were found between 24-h UC excretion and the HDRS score. In fibromyalgia, no significant correlations were found between 24-h UC excretion and the myalgic score. In PTSD, no significant correlations were found between 24-h UC excretion and severity of either depression-avoidance or anxiety-arousal symptoms. In conclusion, this study found increased 24-h UC excretion in patients with PTSD comparable to that in patients with major depression, whereas in fibromyalgia no significant changes in 24-h UC were found.

Abstract
There has been a resurgence of interest in recent years in both chronic fatigue syndrome and fibromyalgia. These perplexing and common clinical conditions are a source of significant patient morbidity and frame one of the more enduring dilemmas of contemporary Western medical thought, namely the ambiguous interface between mind and body. In this article, the current definitions are reviewed, and a framework for an emerging psychobiological model of these syndromes is presented. These issues are synthesized into a pragmatic approach to clinical management.

Abstract
Fibromyalgia (FM) and related syndromes are poorly understood disorders that share symptoms such as pain, fatigue, sleep disturbances, and psychological distress. These syndromes are more common in women, and they are associated with psychological or physical stressors. The neuroendocrine axes are essential physiologic systems that allow for communication between the brain and the body. Interconnections among the neuroendocrine axes lead to coordinate regulation of these systems in both a positive and negative fashion. Several neuroendocrine axes have been shown to be dysfunctional in patients with FM. Although we do not yet understand the relationship between the reported disturbances of neuroendocrine function and the development or maintenance of FM and related syndromes, the authors have proposed that these abnormalities are important in symptomatic manifestations. This article reviews data showing disturbances of the neuroendocrine axes in FM and proposes a hypothesis of the development and maintenance of FM related to neuroendocrine disturbances.

Abstract
OBJECTIVE Recent studies of the relationship between fibromyalgia and psychiatric disorders have yielded conflicting findings, and many of these inconsistencies seem to result from methodological differences. METHOD We compared 36 patients with fibromyalgia and 33 patients with rheumatoid arthritis from a tertiary care clinic using physician-administered, structured psychiatric interviews and self-reported measures of illness appraisal, coping, and functional disability. RESULTS Patients with fibromyalgia had significantly higher lifetime prevalence rates of mood and anxiety disorders, as well as higher mean numbers of medically unexplained physical symptoms across several organ systems. Ninety percent of the patients with fibromyalgia had a prior psychiatric diagnosis compared with less than half of the patients with rheumatoid arthritis. CONCLUSIONS Despite the absence of organic pathology, the patients with fibromyalgia had equal or greater functional disability and were less well adapted to their illness. Although the pathophysiology of fibromyalgia remains unclear, co-morbid psychiatric disorders and functional disability remain an important focus of treatment in this population.

Abstract
Latent variable models of functional somatic symptoms were estimated for a sample of 686 family medicine patients. Symptom items from the NIMH Diagnostic Interview Schedule were selected to approximate diagnoses of fibromyalgia syndrome (FMS), chronic fatigue syndrome (CFS), and irritable bowel syndrome (IBS). Confirmatory factor analysis demonstrated that hypothesized latent variables of somatic depression, somatic anxiety, FM-like, CF-like, and IB-like syndromes fit the observed covariations better than models hypothesizing fewer latent variables. Results offer tentative confirmation of functional somatic syndromes as discrete entities and suggest that relaxing the diagnostic criteria for somatization may identify individuals with distress limited to a single functional system.

Contemporary medicine has the sophistication to identify the clinical settings in which the hunt for a diagnosis can be harmful to a patient's health. Which patients are best served by a prolonged search for a cause? Why has the disease-illness paradigm backfired for so many patients? Dr Hadler challenges readers to look at the difficult questions linked with diagnostic labels that might teach patients to stay sick.

Abstract
OBJECTIVES To study the association of musculoskeletal pain with emotional and behavioral problems, especially depressive symptoms in Finnish preadolescents. STUDY DESIGN A structured pain questionnaire was completed by 1756 third- and fifth-grade schoolchildren for identifying children with widespread pain (WSP), children with neck pain (NP), and pain-free controls for the comparative study. There were 124 children with WSP (mean age, 10.7 years), 108 children with NP (mean age, 11.1 years), and 131 controls (mean age, 10.7 years) who completed the Children's Depression Inventory (CDI) and a sleep questionnaire. A blinded clinical examination was done to detect fibromyalgia. For parental evaluation, the Child Behavior Checklist and a sociodemographic questionnaire were used. For teacher evaluation the Teacher Report Form was used. RESULTS Children with WSP had significantly higher total emotional and behavioral scores than controls, according to child and parent evaluation. A significant difference in the mean total CDI scores was also found between the WSP and NP groups. Children with fibromyalgia had significantly higher CDI scores than the other children with WSP. CONCLUSIONS Musculoskeletal pain, especially fibromyalgia, and depressive symptoms had high comorbidity. Pain and depressive symptoms should be recognized to prevent a chronic pain problem.

Abstract
Breast implants containing silicone have been used for approximately 30 years for breast augmentation or reconstruction. In general, the implants have been well tolerated and reports have indicated a high degree of patient satisfaction. Nonetheless, there have been anecdotal reports of patients with musculoskeletal complaints that have been attributed to silicone breast implants. To investigate this further, we prospectively examined 70 women with silicone breast implants who had complaints that they or their referring physicians thought were related to their implants. On clinical examination, the majority of the patients had fibromyalgia, osteoarthritis, or soft-tissue rheumatism. One patient had rheumatoid arthritis, which predated her implants, and one had Sjõgren's syndrome. Because many of our patients had myalgic symptoms, we further evaluated these patients by measuring circulating levels of soluble factors including interleukin-6, interleukin-8, tumor necrosis factor-alpha, soluble intercellular adhesion molecule-1, and soluble interleukin-2 receptor, which have been previously found to be elevated in patients with inflammatory diseases. We found that the levels of these molecules in women with silicone breast implants were not different from those seen in normal subjects and were significantly less than those seen when examining chronic inflammatory disorders such as rheumatoid arthritis or systemic lupus erythematosus. In summary, our clinical and laboratory evaluation of symptomatic breast implant patients argues against an association of silicone breast implants with a distinctive rheumatic disease or a systemic inflammatory disorder. Given these findings and the clinical picture, it is our impression that most symptomatic women with silicone breast implants have well-delineated noninflammatory musculoskeletal syndromes. Moreover, these data fail to support the concept that their symptoms are due to a systemic inflammatory response related to their implants.

Abstract
Memory functioning was assessed in 25 primary fibromyalgia (FM) patients by comparing them with 22 major depressed patients and 18 healthy controls. A broad range of short- and long-term memory tasks were included. Both major depressed and FM patients were significantly impaired on long-term memory tasks requiring effortful processing, compared to healthy controls. When the depressive status of the fibromyalgia patients was accounted for, only the subsample with a lifetime major depressive disorder showed memory impairment as compared with the healthy controls.

Abstract
Fibromyalgia is a form of nonarticular rheumatism characterized by musculoskeletal aching and tenderness on palpation. The role of psychological factors in fibromyalgia has been controversial. The aim of this study was to evaluate the relationship of fibromyalgia to the intensity of anxiety and depression and to determine the correlation between psychological disturbances with disease duration and pain severity. Thirty-nine patients with fibromyalgia and 36 healthy controls were included in this study. Beck depression inventory, State and trait anxiety inventory and Beck hopelessness scale were used to evaluate psychological disturbances. Visual analog scale was used to determine pain intensity. We found a significant difference in the psychological status between patients with fibromyalgia and control subjects as measured by Beck depression inventory and trait anxiety inventory; 35.9% of the patients scored higher than the cut-off score on the Beck depression rating scale. Pain severity was found to be correlated with trait anxiety inventory scores. These results suggest that somatic expression of depression is an important difference between fibromyalgia and control groups. The difference between state and trait anxiety inventory reflects that current anxiety is not secondary to pain but trait anxiety is possibly causally related to pain.

Abstract
Recognition of fibromyalgia is crucial to avoid extraneous, costly diagnostic testing and ineffective, potentially dangerous therapy. Furthermore, failure to recognize that symptomatic physiologic change does result in a patient's response to stress demeans the legitimate importance of psychiatric disease. The keys to successful therapy are (1) specific pharmacologic manipulation of important processes and prognostic factors, (2) participation in aerobic exercise, which increases time spent in stages 3 and 4 (non-rapid eye movement) sleep and reduces stress, and (3) education, which reduces worry and perceived stress.

Abstract
Looking at the results of the seven types of studies discussed previously, it appears that there is strong evidence for an association between fibromyalgia and major depressive disorder on the basis of (1) overlapping symptomatology, (2) similar pattern of comorbid disorders, and (3) high rates of major depressive disorder among relatives of patients with fibromyalgia. There is additional support for an association on the basis of responses to psychological tests and rating scales and the high lifetime rates of mood disorders in fibromyalgia. Two lines of evidence, (1) response to antidepressant medications and (2) response to biologic tests, offer little evidence either for or against an association. On balance, then the weight of the evidence favors an association between fibromyalgia and major depressive disorder. We therefore turn to an analysis of the nature of the association.

Abstract
CFS and FM are clinical conditions characterized by a variety of nonspecific symptoms including prominent fatigue, myalgia, and sleep disturbances. There are no diagnostic studies or widely accepted, pathogenic, explanatory models for either illness. Despite remarkably different diagnostic criteria, CFS and FM have many demographic and clinical similarities. More specifically, few differences exist in the domains of symptoms, examination findings, laboratory tests, functional status, psychosocial features, and psychiatric disorders. FM appears to represent an additional burden of suffering among those with CFS, however, underscoring the importance of recognizing concurrent CFS and FM. Further clarification of the similarities (and differences) between CFS and FM may be useful in studies of prognosis and help define subsets of patients who may benefit from specific therapeutic interventions.

Abstract
The diagnosis of teh myalgic patient can prove to be challenging for even the most experienced of clinicians. The differential diagnosis includes many diseases that often present with weakness as well as pain. The diagnosis of fibromyalgia may now be made using the positive features of the patient's illness and classified according to well-defined criteria. The process is facilitated by the demonstration of FTPs that are quite specific for the condition. The elicitation of tenderness over these points is highly reliable and valid owing to high intrarater and interrater agreements observed in multiple studies. An algorithmic approach to differential diagnosis is presented. In addition, a stepwise approach to treatment based on published studies and geared to functional outcome measures in put forward in an attempt to encourage a cost-effective approach to care of these difficult patients.

Abstract
Syndromes characterized by chronic pain and fatigue have been described in the medical literature for centuries. Fibromyalgia is the term currently used to describe this symptom complex, and considerable research has been performed in the last decade to delineate the epidemiology, pathophysiology, and genesis of this entity. Although fibromyalgia is defined by its musculoskeletal features, it is clear that there are a large number of non-musculoskeletal symptoms, such that we now understand that there is considerable overlap with allied conditions such as the chronic fatigue syndrome, migraine and tension headaches, irritable bowel syndrome, and affective disorders. This article will review our current state of knowledge regarding fibromyalgia and these allied conditions, and present a unifying hypothesis that describes both the pathophysiology of symptoms and the genesis of these disorders.

Abstract
In order to determine the occurrence of psychological disturbances the authors studied 47 women who fulfilled the American College of Rheumatology Criteria for the classification of fibromyalgia and 25 random selected control patients without chronic muscle pain, all of whom live in Sorocaba, SP, Brazil. Personality disturbances were observable in 63.8% of the patients and 8.0% of the control group (p < 0.05); depression in 80.0% of the fibromyalgia group and 12.0% of the controls (p < 0.05) and anxiety in 63.8% of the patients and 16.0% of the controls (p < 0.05). The Hamilton test mean scores showed higher values for depression and anxiety among the fibromyalgia patients when compared to the control group. A significant association between fibromyalgia and depression, anxiety and personality disturbances was studied and recorded.

Abstract
The nocturnal myoclonus syndrome (NMS) consists of stereotyped, repetitive jerks of the lower limbs that occur during sleep or wakefulness. NMS is often related with restless-legs syndrome (RLS) and can cause severe sleep disturbances and daytime sleepiness. The efficacy of dopamine agonists in the treatment points to a dopaminergic dysfunction in NMS. We investigated the central dopamine D2-receptor occupancy with [123I] labeled (S)-2-hydroxy-3-iodo-6-methoxy-([1-ethyl-2-pyrrolidinyl]methyl) benzamide (IBZM) (a highly selective CNS D2 dopamine receptor ligand) ([123I]IBZM) and single photon emission tomography (SPET) in 20 patients with NMS and in 10 healthy controls. In most of the patients with NMS there was a lower [123I]IBZM binding in the striatal structures compared to controls. The results indicate that NMS is related to a decrease of central D2-receptor occupancy.

Abstract
Given the lack of objective physical measures for assessing fibromyalgia syndrome (FS), the role of pain assessment is particularly important. The role of psychological factors is controversial among FS patients. This study was designed to better understand the relationship between pain behaviors and psychological variables. Specifically, this study (1) refined a pain behavior observation (PBO) methodology for use with FS patients, (2) determined whether stretching is a valid pain behavior, and (3) assessed whether psychological variables including self-efficacy and/or depression can predict pain behaviors after controlling for disease severity and age. The 73 FS subjects meeting the American College of Rheumatology classification system completed questionnaires measuring self-efficacy, depression, and pain. Trained physicians conducted tender-point examinations. Subjects were video-taped using a standardized procedure. Two trained raters independently coded all pain behaviors. Kappa coefficients and correlations among pain behaviors and self-reported pain indicated that the PBO method was both reliable and valid. However, the newly defined pain behavior 'stretching' was found to be negatively associated with self-reported pain. Hierarchical multiple regression (MR) analyses revealed that depression did not predict pain behavior over and above myalgic scores and age; however, in 3 separate MR analyses, self-efficacy for function, pain, and other symptoms each predicted pain behavior over and above myalgic scores and age. This study indicated that the original pain behavior scoring methodology is appropriate for use with the FS population and should not be modified to include the pain behavior 'stretching'. Self-efficacy was related to pain behavior while depression was not among this FS sample.

Abstract
A review of the evidence from diurnal physiological, seasonal environmental and prospective studies of social-behavioural functions suggest that a chronobiological theoretical model provides a comprehensive basis for the dynamics of central nervous system mechanisms, the assessment and the management of patients with fibromyalgia. The chronobiological model stresses the importance of temporal variation and the factors that influence and govern recurrent patterns of biological functions and behaviour that determine health and illness. Finally, the theory allows for an integrated study of brain, behaviour and somatic functions over time and emphasizes that such a comprehensive approach is core to any therapeutic intervention.
