title: [Clinical features, pathophysiology and treatment of fibromyalgia.].
abstract: In rheumatology, all of the more than 400 specified syndromes are associated with pain. In the conceptual discussion on the multidimensional influences postulated to explain the development of chronic pain, fibromyalgia has gained increasing interest. Fibromyalgia (fibrositis) is an unspecific soft-tissue disorder with chronic wide-spread musculoskeletal pain and palpable hypersensitivity at fibrositic tender points. Fibromyalgia is often associated with fatigue, nonrestorative sleep and other symptoms. The syndrome has a high prevalence in women, but in most cases it has a long course with unsatisfactory attempts at therapy before the diagnosis is made. Though diagnostic criteria have been defined to describe it as a distinct clinical syndrome, speculations on its aetiology and pathogenetic mechanisms are still controversial. Histochemical investigations on muscle biopsy and biochemical tests have revealed unspecific changes but no characteristic muscle abnormality. It is supposed that the clinical features may result from central neurohumoral dysfunction combining with peripheral mechanisms to result in hyperalgesia. An integrated therapeutic concept with a reassuring and positive doctor-patient relationship can be helpful in achieving satisfactory treatment results.
