The present article is the result of a working group conference held in Moss, Norway, in June 1993, financed by the Royal Norwegian Ministry of Health and Social Affairs. Its purpose was to review and focus upon problems and needs related to the medico-legal aspects of fibromyalgia and chronic widespread musculoskeletal complaints: thus to define directions for future work on issues which have generally not been addressed within the medical community. Our report describes specific problems in this area in regard to definition, evaluation and recommendation, and in currently available work and disability statistics. We have recommended international efforts to establish research programs through organizations such as the International Social Security Association and the World Health Organization. While our recommendations call for research into medico-legal interactions, causes and pathogenic mechanisms, prevention and treatment are also key and relevant concerns in the medico-legal setting.
The association between chronic widespread musculoskeletal pain complaints and thyroid antibodies in women may reflect a subgroup of patients in which thyroid autoimmunity, rather than thyroid function, is important. A possible relationship to fibromyalgia is discussed as well as a hypothetical role for thyrotropin releasing hormone.
In a previous article from a cross-sectional study of 737 men and 771 women (40-42 years old) in Norway, we found a higher mean serum uric acid in persons with than without chronic musculoskeletal complaints. Furthermore, the odds ratio for chronic complaints increased by increasing uric acid level. Persons with chronic complaints are heterogenous. The scope of the present study was to inquire whether a further breakdown of the material would shed more light upon our previous findings, and thereby contribute to the understanding of the pathogenesis of chronic complaints. Among persons with such complaints, we wished to characterize the ones with the highest serum uric acid. As possible explanatory factors we used the former fibromyalgia minor criteria and modulating factors, and the presence or absence of widespread complaints judged from the Nordic form body map. Persons with chronic widespread weather-dependent complaints had the highest values. The odds ratios for this subgroup increased by increasing uric acid level to a greater extent than reported in our previous article. Some hypotheses about possible action mecanism are put forward, and the relation to fibromyalgia are briefly discussed. Uric acid needs attention in future studies on chronic widespread musculoskeletal complaints.
The relation between chronic musculoskeletal complaints and serum uric acid was examined in 737 men and 771 women (40-42 years old). The study is cross-sectional and part of the National Health Screening Service county studies in Norway. Both men and women with chronic musculoskeletal complaints had significantly higher s-urate means than persons without such complaints. Moreover, the prevalence of chronic musculoskeletal complaints (gout excluded) changed significantly across increasing s-urate levels also within the normal distribution of s-urate. Multivariate logistic regression analysis showed that the s-urate odds ratio for chronic complaints rose in a linear manner across these s-urate levels (adjusted for 12 other independent variables that may interfere with uric acid). Such a relation has not to our knowledge been previously described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
