A 5.5 year prospective study of self-reported musculoskeletal pain and of fibromyalgia in a female population: significance and natural history.

In order to investigate the significance and outcome of self-reported pain and fibromyalgia (FM) in a female population, 214 women with initially self-reported pain were interviewed and examined in 1990 and 1995. In 1990 the sample was categorised into four pain status groups: 46 individuals (21%) with nonchronic (recurrent) pain, 69 (32%) with chronic regional pain 42 (20%) with chronic multifocal pain and 57 with chronic widespread pain (CWP). The last group comprised 39 (18%) women with FM, fulfilling the American College of Rheumatology 1990 criteria. The frequency of tender points, associated symptoms called historical variables and individuals with low education increased statistically significantly with increasing pain status. In 1995, 48 women had non-chronic pain (23%), 46 (21%) chronic regional pain, 39 (18%) chronic multifocal pain and 81 (38%) CWP; of these, 71 (33%) had FM. Eleven of the 39 women initially with FM no longer fulfilled the criteria. The risk of developing CWP among the 157 individuals with initially a lower pain status was statistically higher in women with chronic multifocal pain than in women with less pain extension. Self-reported pain constitutes a continuum of pain severity and thus of clinical and social significance. The overall outcome was poor with an increase of individuals with CWP and FM. The prognosis of chronic multifocal pain, CWP and FM was especially poor. About half of the women with non-chronic pain or chronic regional pain did not deteriorate. However, because the process of developing FM started with localised pain in most cases, self-reported pain of any severity confers a risk for developing FM. Identifying possible risk factors for FM are at present under study and will be presented separately in another report.

Prognostic factors for the development of fibromyalgia in women with self-reported musculoskeletal pain. A prospective study.

OBJECTIVE: To estimate the risk of developing fibromyalgia (FM) in women with self-reported pain and to estimate the relative risk of a series of variables. METHODS: As part of a population study, 214 women with self-reported pain were interviewed and examined in 1990 and 1995. In 1990, 39 of these women fulfilled the American College of Rheumatology criteria for FM. The other 175 women represented a continuum of pain extent from nonchronic pain to chronic widespread pain, and were assessed as individuals at risk for developing FM. Potential risk factors for FM were registered in 1990 and analyzed by bivariate and multiple statistical methods in the total sample and also in a subgroup of 115 women with limited pain. RESULTS: Forty-three (25%) women developed FM. Having > or = 4 associated symptoms, pain of > or = 6 years' duration, back pain, alternately hard/loose stools, and self-assessed depression were found to be predictors. Pain in the lower arm and a feeling of swelling were more weakly associated. In women with limited pain, pain > or = 6 years' duration, > or = 4 associated symptoms, not feeling refreshed in the morning, and paresthesia were found to be predictors. A weaker association was found with self-assessed depression and a lack of formal education. CONCLUSION: A high cumulative incidence of FM was found and a diversity of predictors for FM were identified in the total sample and also in women with limited pain. Of the variables that were part of the FM syndrome, back pain predicted FM, while tender points and pain in the neck did not. Moreover, > or = 4 associated symptoms, self-assessed depression, and longlasting pain were shown to be important predictors.

A population study of the incidence of fibromyalgia among women aged 26-55 yr.

In a population survey, we assessed the incidence of fibromyalgia (FM) among females. A screening questionnaire about pain was distributed twice (in 1990 and 1995) to 2498 females aged 20-49 yr, living in South Norway. A positive answer classified the responder as positive, merely negative answers as negative. One hundred females converting from negative to positive responders and 100 females remaining negative responders (controls) underwent a structural interview and examination for tender points (TP). Of the 870 negative responders in 1990, 717 answered the questionnaire in 1995. Of these, 523 were still negative responders, while 194 were positive converters. Twelve of the converters developed FM and none of the controls. The calculated annual incidence of FM in females was 583/100,000. This rather high incidence is most likely explained by the design of the study, also detecting cases usually not seen in hospital settings.

Multidisciplinary approach to fibromyalgia. A pilot study.

The aim of the study was to instruct a group of fibromyalgia patients how to solve problems related to activities of daily life. Sixteen female fibromyalgia patients completed a ten week multidisciplinary program, consisting of a cognitive and an exercise part. After ten weeks a reduction in general pain intensity (p < 0.05) was found. At six months follow-up sensory (somatic) pain intensity was reduced compared to baseline recordings (p = 0.05). All patients had made adjustments to their everyday life after ten weeks. Eight patients reported that they regularly practised relaxation techniques, and seven patients had undertaken dietary changes. Thus, the study shows that adjustment of activities in daily living may reduce pain in patients with fibromyalgia. Controlled studies are needed in the future.

A bio-psychosocial evaluation of ten adolescents with fibromyalgia.

A comprehensive assessment of 10 adolescents (mean age 15.7 years) fulfilling the ACR criteria for fibromyalgia, disclosed that 3 patients also had juvenile chronic arthritis. Based on semi-structured psychiatric interviews, testing and family assessments, 6 of the patients had a psychiatric diagnosis (over anxious and/or depressive disorders). The pain scores for the group (mean 5.0, SD 1.5) were significantly higher than for a comparison group of patients with juvenile chronic arthritis (mean 2.5, SD 1.7), (p < 0.01). Average IQ was normal (mean 102.3, SD 13.9), but striving for achievement and high parental expectations were evident in 8 families. Seven of the mothers and 3 of the fathers had chronic diseases. The frequency of individual and family stress indicates a need for psychosocial assessment and counselling soon after onset of symptoms. This study also serves as a reminder that the diagnosis of juvenile chronic arthritis does not exclude fibromyalgia.

The occurrence of fibromyalgia-like syndromes in a general female population.

In an epidemiological survey of females aged 20-49 years in Arendal, Norway, 217 persons with musculoskeletal pain were examined for the presence of fibromyalgia as defined by the ACR criteria of 1990. Forty females with fibromyalgia were found whereas 129 females had chronic musculoskeletal pain of more than three months duration but failed to meet the criteria. Two females suffered from nonrheumatic disorders which could explain their musculoskeletal pain. Forty-six females had pain of less than three months duration. Somewhat surprising, the presence of tender points and symptoms regarded as typical of fibromyalgia were rather frequently observed among the females who failed to satisfy the ACR 1990 criteria. No other diseases were found which could explain their complaints or clinical findings. The presence of fibromyalgia-like syndromes is suggested, and the classification and nature of such syndromes are discussed.

The prevalence of fibromyalgia among women aged 20-49 years in Arendal, Norway.

In an epidemiological survey of females aged 20-49 years in Arendal, Norway, a prevalence of fibromyalgia according to the ACR criteria of 1990 of 10.5% was found. Thirty-four out of 40 women with fibromyalgia (85.0%) had, prior to the present population study, consulted a physician because of widespread pain and/or stiffness. Of these 34 women, 14 cases (41.2%) had been given a diagnosis of fibromyalgia. It is concluded that fibromyalgia represents one of the major causes of pain in the locomotor system, and unfortunately, the condition often remains undiagnosed for long periods.

[Reactive arthritis following Yersinia pseudotuberculosis infection].

A patient developed reactive arthritis due to Yersinia pseudotuberculosis. Five months after the primary infection, the patient still suffered from severe oligoarthritis. The administration of steroids and sulphasalazine had very little effect upon the development of the disease.
