The eosinophilic fasciitis (EF) is a rare connective tissue disease characterized by symmetrical and painful swelling with a progressive induration and thickening of the skin and soft tissues. The diagnosis of EF is often based on the association of characteristic skin or subcutaneous abnormalities and a thickened fascia with an inflammatory infiltration, mostly composed of lymphocytes and eosinophils. A peripheral eosinophilia is frequently present, but is not mandatory for the EF diagnosis. ⋯ Differential diagnoses should be ruled out, including eosinophilia-myalgia syndrome (EMS) after L-tryprophane ingestion, hypereosinophilic syndromes (HES), systemic sclerosis, Churg-Strauss syndrome, and/or peripheral T cell lymphomas with cutaneous involvement. Due to the scarcity of the EF disease, there is no consensual therapeutic strategy. However, oral corticosteroids remain the mainstay treatment and may be associated to an immunosuppressive drug such as methotrexate in patients with morphea-like lesions or an unsatisfactory response to corticosteroids alone.

ReviewTai Chi and yoga as complementary therapies in rheumatologic conditions.
Tai Chi and yoga are complementary therapies which have, during the last few decades, emerged as popular treatments for rheumatologic and musculoskeletal diseases. This review covers the evidence of Tai Chi and yoga in the management of rheumatologic diseases, especially osteoarthritis of the knee, hip and hand, and rheumatoid arthritis. ⋯ Recommendations for Tai Chi in knee osteoarthritis have recently been issued by the American College of Rheumatology. To allow broader recommendations for the use of Tai Chi and yoga in rheumatic diseases, there is a need to collect more evidence researched with larger randomised controlled trials.

ReviewCentral pain mechanisms in chronic pain states--maybe it is all in their head.
Mechanisms underlying chronic pain differ from those underlying acute pain. In chronic pain states, central nervous system (CNS) factors appear to play particularly prominent roles. ⋯ The characteristic symptoms of these central pain conditions include multifocal pain, fatigue, insomnia, memory difficulties and a higher rate of co-morbid mood disorders. In contrast to acute and peripheral pain states that are responsive to non-steroidal anti-inflammatory drugs (NSAIDs) and opioids, central pain conditions respond best to CNS neuromodulating agents, such as serotonin-norepinephrine reuptake inhibitors (SNRIs) and anticonvulsants.

ReviewPeripheral pain mechanisms in chronic widespread pain.
Clinical symptoms of chronic widespread pain (CWP) conditions like fibromyalgia (FM), include pain, stiffness, subjective weakness, and muscle fatigue. Muscle pain in CWP is usually described as fluctuating and often associated with local or generalised tenderness (hyperalgesia and/or allodynia). This tenderness related to muscle pain depends on increased peripheral and/or central nervous system responsiveness to peripheral stimuli, which can be either noxious (hyperalgesia) or non-noxious (allodynia). For example, patients with muscle hyperalgesia will rate painful muscle stimuli higher than normal controls, whereas patients with allodynia may perceive light touch as painful, something that a 'normal' individual will never describe as painful. The pathogenesis of such peripheral and/or central nervous system changes in CWP is unclear, but peripheral soft tissue changes have been implicated. Indirect evidence from interventions that attenuate tonic peripheral nociceptive impulses in patients with CWP syndromes like FM suggest that overall FM pain is dependent on peripheral input. More importantly, allodynia and hyperalgesia can be improved or abolished by removal of peripheral impulse input. Another potential mechanism for CWP pain is central disinhibition. However, this pain mechanism also depends on tonic impulse input, even if only inadequately inhibited. Thus, a promising approach to understanding CWP is to determine whether abnormal activity of receptors in deep tissues is fundamental to the development and maintenance of this chronic pain disorder. ⋯ Most CWP patients present with focal tissue abnormalities including myofascial trigger points, ligamentous trigger points or osteoarthritis of the joints and spine. While not predictive for the development of CWP, these changes nevertheless represent important pain generators that may initiate or perpetuate chronic pain. Local chemical mediators, including lactic acid, adenosine triphosphate (ATP) and cytokines, seem to play an important role in sensitising deep tissue nociceptors of CWP patients. Thus, the combination of peripheral impulse input and increased central pain sensitivity may be responsible for widespread chronic pain disorders including FM.

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.
