Diagnosis and management of musculoskeletal pain is a major clinical challenge. Fundamental knowledge of nociception from deep somatic structures and related mechanisms of sensitisation have been characterised in animals but the translation into clinical sciences is still lacking. Development and refinement of mechanism-based quantitative sensory testing in healthy volunteers and pain patients have provided new opportunities to assess pain and hyperalgesic reactions. ⋯ Such a mechanistic approach can be used for differentiated diagnosis and for target validating new and existing analgesics. Mechanistic pain assessment of new compounds under development provides opportunities for target validation in proof-of-concept studies, which generate information to be used for selecting the most optimal patients for later clinical trials. New safe and efficient compounds are highly needed in the area of musculoskeletal pain management.

ReviewNon-pharmacological treatment of chronic widespread musculoskeletal pain.
Individuals with chronic widespread pain, including those with fibromyalgia, pose a particular challenge to treatment, given the modest effectiveness of pharmacological agents for this condition. The growing consensus indicates that the best approach to treatment involves the combination of pharmacological and non-pharmacological interventions. ⋯ The evidence for decreasing pain, improving functioning and changing secondary symptoms is highlighted. Lastly, the methods by which exercise and CBT can be combined for a multi-component approach, which is consistent with the current evidence-based guidelines of several American and European medical societies, are addressed.

There have been substantial advances in the pharmacotherapy of fibromyalgia (FM), which have occurred in parallel with advances in our understanding of the pathophysiology of FM in the past several years. Consortia of researchers have established a core set of symptom domains, which constitute the condition of FM, including pain, fatigue, sleep and mood disturbance and cognitive dysfunction, which significantly impact a patient's overall well-being and ability to function. Outcome measures, which assess these domains, both singly and in composite format, are showing increasing reliability to discriminate between the treatment and placebo arms in clinical trials of emerging therapies, which are targeting the pathophysiologic mechanisms of FM. ⋯ Although combination trials have generally not yet been performed, the combined use of medicines with complementary mechanisms of action is rational, and, when done with appropriate caution, will likely be shown to be safe and well tolerated. Adjunctive therapy with medicines targeted at specific symptom domains, such as sleep, as well as treatments aimed at common co-morbid conditions, such as irritable bowel syndrome, or disease states, such as rheumatoid arthritis, should be considered for the purpose of reducing the patient's overall symptom burden. Current therapies neither completely treat FM symptoms nor benefit all patients; thus, further research on new therapies with different mechanisms and side-effect profiles is needed.

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.
