Abstract: Some patients with fibromyalgia also exhibit the neurological signs of cervical myelopathy. We sought to determine if treatment of cervical myelopathy in patients with fibromyalgia improves the symptoms of fibromyalgia and the patients' quality of life. A non-randomized, prospective, case control study comparing the outcome of surgical (n = 40) versus non-surgical (n = 31) treatment of cervical myelopathy in patients with fibromyalgia was conducted. Outcomes were compared using SF-36, screening test for somatization, HADS, MMPI-2 scale 1 (Hypochondriasis), and self reported severity of symptoms 1 year after treatment. There was no significant difference in initial clinical presentation or demographic characteristics between the patients treated by surgical decompression and those treated by non-surgical means. There was a striking and statistically significant improvement in all symptoms attributed to the fibromyalgia syndrome in the surgical patients but not in the non-surgical patients at 1 year following the treatment of cervical myelopathy (P <or= 0.018-0.001, Chi-square or Fisher's exact test). At the 1 year follow-up, there was a statistically significant improvement in both physical and mental quality of life as measured by the SF-36 score for the surgical group as compared to the non-surgical group (Repeated Measures ANOVA P < 0.01). There was a statistically significant improvement in the scores from Scale 1 of the MMPI-2 and the screening test for somatization disorder, and the anxiety and depression scores exclusively in the surgical patients (Wilcoxon signed rank, P < 0.001). The surgical treatment of cervical myelopathy due to spinal cord or caudal brainstem compression in patients carrying the diagnosis of fibromyalgia can result in a significant improvement in a wide array of symptoms usually attributed to fibromyalgia with attendant measurable improvements in the quality of life. We recommend detailed neurological and neuroradiological evaluation of patients with fibromyalgia in order to exclude compressive cervical myelopathy, a potentially treatable condition.

Abstract: BACKGROUND: Fibromyalgia syndrome (FMS) involves multiple sensory, somatic, and cognitive symptoms that are bound to affect or be affected by physical and mental health status and behavioral components of daily life. METHODS: From a telephone survey of 442 women with and 205 women without FMS as volunteers, data were compared on (1) general health status, (2) reproductive and sleep-related diagnoses, and (3) lifestyle health behaviors. RESULTS: All multiple or logistics regression analyses for group differences were controlled for age, body mass index (BMI), race, employment status, marital status, having a college degree, low household income, and having ever been diagnosed with depression, with a Bonferroni p value correction for multiple indicators. Accordingly, FMS negatively impacted both perceived physical and mental health status, although relatively more so for physical (p < 0.017). Women with FMS were more likely to have had reproductive health or sleep-related diagnoses, including premenstrual syndrome, dysmenorrhea, breast cysts, bladder cystitis, sleep apnea, restless leg syndrome, and abnormal leg movements (p < 0.0125). They were calculated to use less than half as many calories per week as control women (689 +/- 1293 vs. 1499 +/- 1584 kcal/week, p < 0.05) and had more sleep pattern difficulties (p < 0.0125), more negative changes in sexual function (greater odds for 5 of 10 indicators at p < 0.005), and lower alcohol use (odds ratio = 0.39, p < 0.05). CONCLUSIONS: Patients with FMS deserve careful assessment for reproductive conditions and sleep-related functional disorders. Besides more research into mechanisms underlying symptoms, intervention testing specifically to alleviate sleep problems, low physical activity levels, and sexual dysfunction should be paramount.

Abstract: This study was designed to determine the prevalence and positive predictive value of isolated antinucleolar antibody (ANA) in scleroderma patients. We identified 73 rheumatology clinic patients with isolated ANAs. ANA titers greater than 1:160 were considered positive. The overall prevalence of isolated ANAs was 2.9%. The prevalence of isolated ANAs in scleroderma, systemic lupus erythematosus (SLE), and rheumatoid arthritis were 20.3%, 2.68%, and 3.3%, respectively. Scleroderma and SLE were present in 12 patients (16.4%) each. Other rheumatologic disorders identified in these patients were RA (12.3%), undifferentiated connective tissue disease (8.2%), mixed connective tissue disease (4.1%), vasculitis (6.8%), fibromyalgia (8.2%), osteoarthritis (5.4%), crystal-related arthropathy (6.8%), seronegative arthritis (2.7%), sarcoidosis (4.1%), and others (8.2%). There were no statistically significant differences in the median ANA titers in scleroderma versus systemic lupus (P = 0.16) or undifferentiated connective tissue disease (P = 0.18). The median titers were higher in scleroderma in comparison with rheumatoid arthritis (P = 0.01), osteoarthritis (P = 0.007), fibromyalgia (P = 0.001), and crystal-related arthropathy (P = 0.009). Isolated ANAs have poor sensitivity (20.3%) and the positive predictive value for this test is only 16.4% for scleroderma.

Abstract: Memory decline and mental confusion frequently complicate the clinical presentation of fibromyalgia; however, formal cognitive examination often does not support deterioration. This paradox was examined in the context of dissociation, a condition with many cognitive similarities. Dissociation refers to the separation of parts of experience from the mainstream of consciousness. A common example is highway hypnosis. Eighty-nine fibromyalgia (FM) patients and 64 other rheumatic disease patients were screened for memory decline and mental confusion using a questionnaire format. Pain, dissociation, affective distress, fatigue, sleep difficulty, and mental confusion were also assessed. Cognitive complaints (76.4%-43.8%) and dissociative symptoms (37.1%-1.9%) were overrepresented in patients with FM. Among FM patients with high dissociation, cognitive difficulties were reported by 95%; 100% of these cases reported that both memory and mental clarity were affected, a condition referred to as fibrofog. Dissociation in combination with fibrofog was associated with higher levels of FM symptom intensity and decreased mental well being. These findings suggest that dissociation may play a role in FM symptom amplification and may aid in comprehending the regularity of cognitive symptoms. Separating cases of fibrofog from cognitive conditions with actual brain damage is important. It may be prudent to add a test of dissociation as an adjunct to the evaluation of FM patients in cases of suspected fibrofog. Otherwise, test results may prove normal even in patients with disabling cognitive symptoms.

Abstract: We aimed to determine how menopausal transition symptoms cluster across 216 midlife women with fibromyalgia, chronic fatigue syndromes (FMS/CFS), or both and subsequently to compare symptom factor severity scores by menopausal status among these women and compare symptom reporting with prior community-based samples of women without obvious illness. We designed a cross-sectional telephone survey of 216 women aged 35 to 55, diagnosed with FMS/CFS, symptomatic in the prior 6 months, and without hysterectomy. Thirty-six of 61 symptoms loaded on five factors: aroused/anxious mood, depressed mood/withdrawal, musculoskeletal, gastrointestinal (GI), and vasomotor. Peri- and postmenopausal women had higher symptom severity scores for musculoskeletal, GI, and vasomotor factors but not mood factors. Symptoms for the women we studied who had FMS/CFS clustered similar to those in previous community-based samples of midlife women without major illness; however, the number of women experiencing symptoms was much higher among our sample.

Abstract: Previous studies of the association between posttraumatic stress disorder (PTSD) and chronic widespread pain (CWP) or fibromyalgia have not examined the role of familial or genetic factors. The goals of this study were to determine if symptoms of PTSD are related to CWP in a genetically informative community-based sample of twin pairs, and if so, to ascertain if the association is due to familial or genetic factors. Data were obtained from the University of Washington Twin Registry, which contains 1042 monozygotic and 828 dizygotic twin pairs. To assess the symptoms of PTSD, we used questions from the Impact of Events Scale (IES). IES scores were partitioned into terciles. CWP was defined as pain located in 3 body regions lasting at least 1 week during the past 3 months. Random-effects regression models, adjusted for demographic features and depression, examined the relationship between IES and CWP. IES scores were strongly associated with CWP (P<0.0001). Compared to those in the lowest IES tercile, twins in the highest tercile were 3.5 times more likely to report CWP. Although IES scores were associated with CWP more strongly among dizygotic than among monozygotic twins, this difference was not significant. Our findings suggest that PTSD symptoms, as measured by IES, are strongly linked to CWP, but this association is not explained by a common familial or genetic vulnerability to both conditions. Future research is needed to understand the temporal association of PTSD and CWP, as well as the physiological underpinnings of this relationship.

Abstract: PURPOSE: Numerous studies have been performed to identify potential risk factors for CP/CPPS and IC. 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.

Abstract: OBJECTIVE: To present the case of a collegiate tennis player with celiac disease symptoms. BACKGROUND: Celiac disease is a common intestinal disorder that is often confused with other conditions. It causes severe intestinal damage manifested by several uncomfortable signs and symptoms. Failure by the sports medicine staff to recognize symptoms consistent with celiac disease and treat them appropriately can have deleterious consequences for the athlete. DIFFERENTIAL DIAGNOSIS: Irritable bowel syndrome, Crohn disease, Addison disease, lupus erythematosus, juvenile rheumatoid arthritis, lactose intolerance, herpes zoster, psychogenic disorder (depression), fibromyalgia, complex regional pain syndrome, hyperthyroidism, anemia, type I diabetes. TREATMENT: The athlete underwent a series of blood and allergen tests to confirm or refute a diagnosis of celiac disease. When celiac disease was suspected, dietary modifications were made to eliminate all wheat-based and gluten-based products from the athlete's diet. UNIQUENESS: The athlete was able to fully compete in a competitive National Collegiate Athletic Association Division I tennis program while experiencing the debilitating effects associated with celiac disease. The immediacy of symptom onset was notable because the athlete had no history of similar complaints. CONCLUSIONS: Celiac disease is a potentially life-threatening condition that affects more people than reported. A properly educated sports medicine staff can help to identify symptoms consistent with celiac disease early, so damage to the intestine is minimized. Prompt recognition and appropriate management allow the athlete to adjust the diet accordingly, compete at a high-caliber level, and enjoy a healthier quality of life.

Abstract: 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.

Abstract: 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.

Abstract: OBJECTIVE: While patients with fibromyalgia report symptoms consistent with cervical myelopathy, a detailed neurological evaluation is not routine. We sought to determine if patients with fibromyalgia manifest objective neurological signs of cervical myelopathy. METHODS: Two hundred and seventy patients, 18 years and older, who carried the diagnosis of fibromyalgia but who had no previously recognized neurological disease underwent detailed clinical neurological and neuroradiological evaluation for the prevalence of objective evidence of cervical myelopathy and radiological evidence of cerebellar tonsillar herniation (Chiari 1 malformation) or cervical spinal canal stenosis. RESULTS: Patients were primarily women (87%), of mean age 44 years, who had been symptomatic for 8 years (standard deviation, 6.3 years). The predominant complaints were neck/back pain (95%), fatigue (95%), exertional fatigue (96%), cognitive impairment (92%), instability of gait (85%), grip weakness (83%), paresthesiae (80%), dizziness (71%) and numbness (69%). Eighty-eight percent of patients reported worsening symptoms with neck extension. The neurological examination was consistent with cervical myelopathy: upper thoracic spinothalamic sensory level (83%), hyperreflexia (64%), inversion of the radial periosteal reflex (57%), positive Romberg sign (28%), ankle clonus (25%), positive Hoffman sign (26%), impaired tandem walk (23%), dysmetria (15%) and dysdiadochokinesia (13%). MRI and contrast-enhanced CT imaging of the cervical spine revealed stenosis. The mean antero-posterior (AP) spinal canal diameter at C2/3, C3/4, C4/5, C5/6, C6/7 and C7/T1 was 13.5 mm, 11.8 mm, 11.5 mm, 10.4 mm, 11.3 mm and 14.5 mm respectively, (CT images). In 46% of patients, the AP spinal diameter at C5/6 measured 10 mm, or less, with the neck positioned in mild extension, i.e., clinically significant spinal canal stenosis. MRI of the brain revealed tonsillar ectopia >5 mm in 20% of patients (mean=7.1+/-1.8 mm), i.e., Chiari 1 malformation. CONCLUSION. Our findings indicate that some patients who carry the diagnosis of fibromyalgia have both signs and symptoms consistent with cervical myelopathy, most likely resulting from spinal cord compression. We recommend detailed neurological evaluation of patients with fibromyalgia in order to exclude cervical myelopathy, a potentially treatable condition.

Abstract: Identifying the cause of polyarticular joint pain can be difficult because of the extensive differential diagnosis. A thorough history and a complete physical examination are essential. Six clinical factors are helpful in narrowing the possible causes: disease chronology, inflammation, distribution, extra-articular manifestations, disease course, and patient demographics. Patients with an inflammatory arthritis are more likely to have palpable synovitis and morning stiffness; if the condition is severe, they may have fever, weight loss, and fatigue. Viral infections, crystal-induced arthritis, and serum sickness reactions are common causes of acute, self-limited polyarthritis. Because chronic arthritides may present abruptly, they need to be considered in patients who present with acute polyarticular joint pain. Joint palpation can help to distinguish inflammatory synovitis from the bony hypertrophy and crepitus that typically occur with osteoarthritis. Extra-articular manifestations of rheumatologic disease may be helpful in arriving at a more specific diagnosis. Many classic rheumatologic laboratory tests are nonspecific. A complete blood count, urinalysis, and a metabolic panel may provide more useful diagnostic clues. Plain-film radiographs may demonstrate classic findings of specific rheumatologic diseases; however, radiographs can be normal or only show nonspecific changes early in the disease process.

Abstract: OBJECTIVE: The objective of this study was to examine a possible relationship between smoking and fibromyalgia features among 233 female patients with fibromyalgia syndrome. METHODS: Data on clinical and psychological features were collected by a protocol. Smoking status was evaluated by a question inquiring about the packs of cigarettes smoked per day. Differences between the smokers and non-smokers were tested by Mann Whitney U test. To adjust data for age and education, a partial correlation test was used. A p value of < or = 0.01 was accepted as the level of significance. RESULTS: Fifty-one patients (21.9%) smoked. After adjustment for age and education, significantly positive relationship was found between smoking and pain, patient global severity, functional disability, and numbness. There was no difference between smokers and non-smokers for fatigue, morning fatigue, sleep difficulties, tender points (TP), depression, anxiety and stress. CONCLUSIONS: Smokers reported significantly more pain, numbness, patient global severity, and functional difficulties than non-smokers. There was no significant difference between smokers and non-smokers for fatigue and TP.

Abstract: OBJECTIVE: to evaluate the relationship between body mass index (BMI) and features of the fibromyalgia syndrome (FMS). METHODS: 211 female patients with FMS seen consecutively in our rheumatology clinic were analyzed. Spearman correlation was used. Further, FMS features were compared at different levels of BMI (kg/m2), e.g., < 25.00 vs > or = 25.00 (normal vs overweight). P value of < or = 0.01 was accepted as significant. RESULTS: A significant positive correlation was found between BMI and age (p<0.001) and a negative correlation between BMI and education (p<0.009). Health Assessment Questionnaire (HAQ) score was significantly correlated with BMI (p<0.001), whereas fatigue and number of tender points (TP) showed a trend (p=0.035 and 0.037, respectively). CONCLUSION: The HAQ score is significantly associated with BMI in FMS with a trend towards significance for fatigue and TP. Weight loss may improve physical functioning in this disorder.

Abstract: OBJECTIVE: The aim of this study was to determine illness comorbidity rates for individuals with chronic fatigue syndrome (CFS), fibromyalgia (FM), and multiple chemical sensitivities (MCS). An additional objective was to identify characteristics related to the severity of fatigue, disability, and psychiatric comorbidity in each of these illness groups. METHODS: A random sample of 18,675 residents in Chicago, Illinois, was first interviewed by telephone. A control group and a group of individuals with chronic fatigue accompanied by at least four minor symptoms associated with CFS received medical and psychiatric examinations. RESULTS: Of the 32 individuals with CFS, 40.6% met criteria for MCS and 15.6% met criteria for FM. Individuals with MCS or more than one diagnosis reported more physical fatigue than those with no diagnosis. Individuals with more than one diagnosis also reported greater mental fatigue and were less likely to be working than those with no diagnosis. Individuals with CFS, MCS, FM, or more than one diagnosis reported greater disability than those with no diagnosis. CONCLUSIONS: Rates of coexisting disorders were lower than those reported in prior studies. Discrepancies may be in part attributable to differences in sampling procedures. People with CFS, MCS, or FM endure significant disability in terms of physical, occupational, and social functioning, and those with more than one of these diagnoses also report greater severity of physical and mental fatigue. The findings illustrate differences among the illness groups in the range of functional impairment experienced.

Abstract: OBJECTIVE: The goal of this study was to assess clinical consensus regarding whether myofascial pain syndrome (MPS) is a legitimate and distinct diagnosis as well as the signs and symptoms characterizing MPS. DESIGN: A standardized mailed survey with return postage provided. SUBJECTS: A total of 1,663 American Pain Society members in medically related disciplines listed in the 1996/1997 directory. OUTCOME MEASURES: A standardized survey assessing clinical opinion regarding whether MPS is a legitimate diagnosis, whether MPS is a clinical entity distinct from fibromyalgia, and the signs and symptoms believed to be "essential to," "associated with," or "irrelevant to" to the diagnosis of MPS. RESULTS: Of the 403 surveys returned, 88.5% respondents reported that MPS was a legitimate diagnosis, with 81% describing MPS as distinct from fibromyalgia. The only signs and symptoms described as essential to the diagnosis of MPS by greater than 50% of the sample were regional location, presence of trigger points, and a normal neurologic examination. Regarding the signs and symptoms considered to be essential or associated with MPS, more than 80% of respondents agreed on regional location, trigger points, normal neurologic examination, reduced pain with local anesthetic or "spray and stretch," taut bands, tender points, palpable nodules, muscle ropiness, decreased range of motion, pain exacerbated by stress, and regional pain described as "dull," "achy," or "deep." Sensory or reflex abnormalities, scar tissue, and most test results were considered to be irrelevant to the diagnosis of MPS by a large proportion of the respondents. CONCLUSIONS: There was general agreement across specialties that MPS is a legitimate diagnosis distinct from fibromyalgia. There was a high level of agreement regarding the signs and symptoms essential or associated with a diagnosis of MPS. Differences across specialties are discussed. This survey provides a first step toward the development of consensus-based diagnostic criteria for MPS, which can then be validated empirically.

Abstract: OBJECTIVE: To describe possible differences between male and female patients with fibromyalgia syndrome (FM) in their clinical manifestations. METHODS: Five hundred thirty-six consecutive patients with FM (469 women, 67 men) seen in a university rheumatology clinic and 36 healthy men without significant pain seen in the same clinic were included in the study. Data on demographic and clinical features were gathered by a standard protocol. Tender point examination was performed by the same physician. Level of significance was set at p < or = 0.01. RESULTS: Several features were significantly (p < or = 0.01) milder or less common among men than women, including number of tender points (TP), TP score, "hurt all over," fatigue, morning fatigue, and irritable bowel syndrome (IBS). The total number of symptoms was also fewer among men and approached significance (p = 0.02) by parametric test, but reached significance (p = 0.001) by nonparametric analysis. All clinical and psychological symptoms as well as TP were significantly (p < 0.01) more common or greater in male patients with FM than healthy male controls, with the exception of IBS (p = 0.03). Patient assessed global severity of illness, Health Assessment Questionnaire disability score, and pain severity were similar in both sexes. CONCLUSION: Male patients with FM had fever symptoms and fewer TP, and less common "hurt all over," fatigue, morning fatigue, and IBS, compared with female patients. Stepwise logistic regression showed significant differences between men and women in number of TP (p < 0.001).

Abstract: OBJECTIVE: Based on the reports of familial aggregation of fibromyalgia (FM) syndrome, we investigated its possible genetic linkage to HLA by studying multicase families. METHODS: Forty Caucasian multicase families with a diagnosis of FM (American College of Rheumatology criteria) in 2 or more first degree relatives were investigated. Eighty-five affected and 21 unaffected members of 41 sibships were studied. Depression symptomology was assessed by Zung Self-rating Depression Scale (SDS). HLA typing was performed for A, B, and DRB 1 alleles, and haplotypes were determined with no knowledge of the subject's diagnosis. We investigated genetic linkage to the HLA region by evaluating sibships in multicase families. RESULTS: Sibship analysis showed significant genetic linkage of FM to the HLA region (p = 0.028). Subgroup analysis was also performed for 17 families where the proband was also noted to have depression (with an SDS index value > or =60). We found that the presence of depression did not influence the observed results (p = 0.22). CONCLUSION:. Our study of 40 multicase families confirms existence of a possible gene for FM that is linked with the HLA region. Our results should be regarded as preliminary and their independent confirmation by other studies is warranted.
