Chest wall tenderness is unhelpful in the diagnosis of recurrent chest pain.
(33/737)
We investigated whether the presence of chest wall tenderness or fibromyalgia helped to distinguish between ischaemic and non-ischaemic chest pain. Seventy-one patients with recurrent chest pain, 36 with normal (group A) and 35 with abnormal coronary angiograms (group B), were assessed by investigator-administered questionnaires, and were examined for chest wall tenderness and fibromyalgia by a single blinded observer. Chest wall tenderness was greater in group A. However, it was much greater in women, who predominated in group A, than in men, who predominated in group B, and this explained the intergroup difference. Seven patients (25%) (six female, one male) in the group A and one patient (3%) (male) in group B (chi(2) p=0.027) fulfilled criteria for fibromyalgia. Patients with recurrent chest pain are more likely to have a ischaemic cause if they are male. Although our study suggests that chest wall tenderness alone in patients with recurrent chest pain has no value in excluding myocardial ischaemia as a cause, the confounding factor of gender prevents our study design from answering this question conclusively. Fibromyalgia is commoner in patients with chest pain and normal coronary angiograms, but may be related to the excess of females in this group. Its presence does not preclude the co-existence of ischaemic heart disease. (+info)
Pain evaluation of patients with fibromyalgia, osteoarthritis, and low back pain.
(34/737)
The purpose of this study was to evaluate and compare pain as reported by outpatients with fibromyalgia, osteoarthritis, and low back pain, in view of designing more adequate physical therapy treatment. PATIENTS AND METHODS: A Portuguese version of the McGill Pain Questionnaire - where subjects are asked to choose, from lists of pre-categorized words, one or none that best describes what they feel - was used to assess pain intensity and quality of 64 patients, of which 24 had fibromyalgia, 22 had osteoarthritis, and 18 had low back pain. The pre-categorized words were organized into 4 major classes - sensory, affective, evaluative, and miscellaneous. RESULTS: Patients with fibromyalgia reported, comparatively, more intense pain through their choice of pain descriptors, both sensory and affective; they also chose a higher number of words from these classes than patients in the other groups and were the only ones to choose specific affective descriptors such as "vicious", "wretched", "exhausting", "blinding". CONCLUSION: Assuming that each disease presents unique qualities of pain experience, and that these can be pointed out by means of this questionnaire by patients' choice of specific groups of words, the findings suggest that fibromyalgia include not only a physical component, but also a psycho-emotional component, indicating that they require both emotional/affective and physical care.

A practical approach to fibromyalgia.
(35/737)
The term fibromyalgia refers to a collection of symptoms with no clear physiologic cause, but the symptoms together constitute a clearly recognizable and distinct pathologic entity. The diagnosis is made through the examiner's clinical observations. The differential diagnosis must include other somatic syndromes as well as disease entities, including hepatitis, hypothyroidism, diabetes mellitus, electrolyte imbalance, multiple sclerosis, and cancer. Diagnostic criteria serve as guidelines for diagnosis, not as absolute requirements. Treatment of fibromyalgia, which is an ongoing process, remains individualized, relying on a good physician-patient relationship. It is goal-oriented, directed at helping patients get restorative sleep, alleviating the somatic pains, keeping patients productive, and regulating schedules. It can be achieved through a goal-oriented agreement between patient and provider. Because fibromyalgia is chronic and may affect all areas of an individual's functioning, the physician needs to also evaluate the social support systems of patients with fibromyalgia. The approach to treatment should integrate patient education as well as non-pharmacologic and pharmacologic modalities. To keep patients well educated and involved in their healthcare, physicians should provide patients with adequate sources for reliable information. (+info)
Cytokines play an aetiopathogenetic role in fibromyalgia: a hypothesis and pilot study.
(36/737)
OBJECTIVE: To measure soluble factors having a possible role in fibromyalgia (FM) and compare the profiles of patients with recent onset of the syndrome with patients with chronic FM. METHODS: The production of cytokines, cytokine-related molecules, and a CXC chemokine, interleukin (IL)-8, was examined. Fifty-six patients with FM (23 with <2 yr and 33 with >2 yr of symptoms) were compared with age- and sex-matched healthy controls. Cytokines and cytokine-related molecules were measured in sera and in supernatants of peripheral blood mononuclear cells (PBMC) that were incubated with and without lectins and phorbol myristate acetate (PMA). RESULTS: No differences between FMS and controls were found by measuring IL-1beta, IL-2, IL-10, serum IL-2 receptor (sIL-2R), interferon gamma (IFN-gamma), and tumour necrosis factor alpha (TNF-alpha). Levels of IL-1R antibody (IL-1Ra) and IL-8 were significantly higher in sera, and IL-1Ra and IL-6 were significantly higher in stimulated and unstimulated FM PBMC compared with controls. Serum IL-6 levels were comparable to those in controls, but were elevated in supernatants of in vitro-activated PBMC derived from patients with >2 yr of symptoms. In the presence of PMA, there were additional increases in IL-1Ra, IL-8 and IL-6 over control values. CONCLUSIONS: In patients with FM we found increases over time in serum levels and/or PBMC-stimulated activity of soluble factors whose release is stimulated by substance P. Because IL-8 promotes sympathetic pain and IL-6 induces hyperalgesia, fatigue and depression, it is hypothesized that they may play a role in modulating FM symptoms. (+info)
Autoantibodies to a 68/48 kDa protein in chronic fatigue syndrome and primary fibromyalgia: a possible marker for hypersomnia and cognitive disorders.
(37/737)
OBJECTIVE: To identify antinuclear antibodies (ANA) specific for chronic fatigue syndrome (CFS), and in related conditions such as fibromyalgia (FM) or psychiatric disorders. METHODS: One hundred and fourteen CFS patients and 125 primary and secondary FM patients were selected based on criteria advocated by the Centers for Disease Control and Prevention and by the American College of Rheumatology, respectively. As controls, healthy subjects and patients with either various psychiatric disorders or diffuse connective tissue diseases were included. Autoantibodies were examined by immunoblot utilizing HeLa cell extracts as the antigen. RESULTS: Autoantibodies to a 68/48 kDa protein were present in 13.2 and 15.6% of patients with CFS and primary FM, respectively. In addition, autoantibodies to a 45 kDa protein were found in 37.1 and 21.6% of the patients with secondary FM and psychiatric disorders, respectively. Meanwhile, these two autoantibodies were not found at all in connective tissue disease patients without FM, nor in healthy subjects (P<0.05). As a group, the anti-68/48 kDa-positive CFS patients presented more frequently with hypersomnia (P<0.005), short-term amnesia (P<0.07) or difficulty in concentration (P<0.05) than those CFS patients without the antibodies. CONCLUSIONS: The presence of the anti-68/48 kDa protein antibodies in a portion of both CFS and primary FM patients suggests the existence of a common immunological background. These antibodies may find utility as possible markers for a clinicoserological subset of CFS/FM patients with hypersomnia and cognitive complaints. (+info)
Pain and pain relief in fibromyalgia patients followed for three years.
(38/737)
OBJECTIVE: To examine the natural clinical course of pain in fibromyalgia (FM) and patients' reports of the use of interventions for pain relief. METHODS: This prospective 3-year study examined pain, and the treatment thereof, in a cohort of 82 women with FM, of whom 59 (72%) were reassessed on 3 subsequent occasions. Pain was measured by the following parameters: visual analog scale (VASpain), tender point count (TP), and the occurrence of widespread pain (WP). Function was assessed by the Health Assessment Questionnaire and the Fibromyalgia Impact Questionnaire, and depression and anxiety by the Arthritis Impact Measurement Scales. All treatments for FM were recorded, and patients identified the treatment that they believed had helped their symptoms of FM. RESULTS: Pain reporting as measured by all parameters decreased significantly for the whole group over the duration of the study. The mean VASpain decreased from 66 to 55, the mean TP count decreased from 13.5 to 10.5, and the number of patients with WP decreased from 100% to 63%. VASpain correlated positively with TP and WP. One third of patients experienced a reduction in pain by at least 30% from baseline as well as a better outcome in overall status of FM. There was a decline in the use of prescribed medications, whereas the use of alternative products increased. Physical treatment modalities were more often perceived to be of benefit than prescribed medications. CONCLUSION: We have observed a spontaneous improvement in pain reporting and less medication use in FM patients, suggesting that the course of this condition may be more favorable than has previously been reported.

Psychosocial and health status variables independently predict health care seeking in fibromyalgia.
(39/737)
OBJECTIVE: To determine whether variables derived from the self-regulatory model of health and illness behavior accurately predict status as a patient or nonpatient with fibromyalgia (FM). METHODS: Subjects were 79 patients who met American College of Rheumatology (ACR) criteria for FM and 39 community residents who met ACR criteria for FM but had not sought medical care for their symptoms (nonpatients). Subjects were administered 14 measures that produced 6 domains of variables: background demographics and pain duration; psychiatric morbidity; and personality, environmental, cognitive, and health status factors. These domains were entered in 4 different hierarchical logistic regression analyses to predict status as patient or nonpatient. RESULTS: The full regression model was statistically significant (P < 0.0001) and correctly identified 90.7% of the subjects with a sensitivity of 92.4% and a specificity of 87.2%. The best individual predictors of group status were self-reports of self-efficacy, negative affect, recent stressful events, and perceived pain. Relative to nonpatients, patients reported higher levels of negative affect and perceived pain and a greater number of recent stressful experiences, as well as lower levels of self-efficacy. CONCLUSION: Consistent with the self-regulatory model of health and illness behavior, psychosocial and health status variables predict health care-seeking behavior in persons with FM independently of background demographics and psychiatric morbidity. These variables may influence the severity of symptoms experienced by persons with this disorder as well as their health care-seeking behavior, but they are not necessary to produce abnormal pain sensitivity in FM.

Widespread body pain and mortality: prospective population based study.
(40/737)
OBJECTIVE: To determine whether there is excess mortality in groups of people who report widespread body pain, and if so to establish the nature and extent of any excess. DESIGN: Prospective follow up study over eight years. Mortality rate ratios were adjusted for age group, sex, and study location. SETTING: North west England. PARTICIPANTS: 6569 people who took part in two pain surveys during 1991-2. MAIN OUTCOME MEASURES: Pain status at baseline and subsequent mortality. RESULTS: 1005 (15%) participants had widespread pain, 3176 (48%) had regional pain, and 2388 (36%) had no pain. During follow up mortality was higher in people with regional pain (mortality rate ratio 1.21, 95% confidence interval 1.01 to 1.44) and widespread pain (1.31, 1.05 to 1.65) than in those who reported no pain. The excess mortality among people with regional and widespread pain was almost entirely related to deaths from cancer (1.55 (1.09 to 2.19) for regional pain and 2.07 (1.37 to 3.13) for widespread pain). The excess cancer mortality remained after exclusion of people in whom cancer had been diagnosed before the original survey and after adjustment for potential confounding factors. There were also more deaths from causes other than disease (for example, accidents, suicide, violence) among people with widespread pain (5.21, 0.94 to 28.78). CONCLUSION: There is an intriguing association between the report of widespread pain and subsequent death from cancer in the medium and long term. This may have implications for the long term follow up of patients with "unexplained" widespread pain symptoms, such as those with fibromyalgia. (+info)
