ReviewChronic widespread pain in the spectrum of rheumatological diseases.
Fibromyalgia (FM) is a rheumatic disease characterised by musculoskeletal pain, chronic diffuse tension and/or stiffness in joints and muscles, fatigue, sleep and emotional disturbances and pressure pain sensitivity in at least 11 of 18 tender points. There are currently no instrumental tests or specific diagnostic markers, and the characteristic symptoms of the disease overlap those of many other conditions classified in a different manner. FM is often associated with other diseases that act as confounding and aggravating factors, including primary Sjögren's syndrome (pSS), systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). ⋯ The presence of diffuse pain in autoimmune rheumatic diseases compromises the quality of life of the patients, although overall mortality is not increased. A misdiagnosis harms the patients and the community. Rheumatologists should be able to recognise and distinguish primary and secondary FM, and need new guidelines and instruments to avoid making mistakes.

ReviewTrauma and work-related pain syndromes: risk factors, clinical picture, insurance and law interventions.
In the past decade, major progress has been made in our understanding of fibromyalgia syndrome (FMS). Various triggers have been implicated as contributing to symptom development in FMS when genetically susceptible individuals are challenged. A substantial amount of data points towards the association between trauma and chronic widespread pain/fibromyalgia syndrome (CWP/FMS). ⋯ Furthermore, several persistent local pain conditions may progress to CWP/FMS. These conditions may share a common pathogenic mechanism namely, central sensitisation. Physical trauma and emotional trauma co-exist in many traumatic events and may interact in the pathogenesis of CWP/FMS.

Chronic widespread pain (CWP) due to musculoskeletal conditions is a major social burden. The case definition of CWP relies on pain, chronicity (more than 3 months' duration) and widespread distribution (both sides of the body including the axial skeleton). Health Interview Survey (HIS) and Health Examination Survey (HES) have been used to assess the frequency of CWP in the general population. ⋯ Issues to be addressed include: (1) loss of daily life functions due to pain; (2) pain duration and rhythm; (3) affected sites; and (4) type of pain. We know that musculoskeletal pain affects between 13.5% and 47% of the general population, with CWP prevalence varying between 11.4% and 24%. Risk factors for musculoskeletal pain include age, gender, smoking, low education, low physical activity, poor social interaction, low family income, depression, anxiety and sleep disorders, as well as performing manual work, being a recent immigrant, non-Caucasian and widowed, separated or divorced.

Future perspectives in generalised musculoskeletal pain syndromes.
This article describes contemporary controversies regarding two categories of soft-tissue pain (STP)--chronic widespread pain and fibromyalgia syndrome. The tone is more editorial than review didactic. It draws upon history to explain current trends that project possible future implications. ⋯ The populations identified by the two criteria are similar but not identical. Misuse of the new criteria could expand fibromyalgia from 2 to 10% of the general population. Avoidance of the term 'fibromyalgia' could return it to the obscurity from whence it came, leaving a much larger problem in its stead.

This article reviews the available published knowledge about the diagnosis, pathophysiology and treatment of myofascial pain syndromes from trigger points. Furthermore, epidemiologic data and clinical characteristics of these syndromes are described, including a detailed account of sensory changes that occur at both painful and nonpainful sites and their utility for diagnosis and differential diagnosis; the identification/diagnostic criteria available so far are critically reviewed. ⋯ Current hypotheses on the pathophysiology of myofascial pain syndromes are presented, including mechanisms of formation and persistence of primary and secondary trigger points as well as mechanisms beyond referred pain and hyperalgesia from trigger points. Conventional and most recent therapeutic options for these syndromes are described, and their validity is discussed on the basis of results from clinical controlled studies.
