This survey was designed to examine features of a group of patients with acute painful joint effusions following hylan G-F 20 (Synvisc) knee injections. ⋯ The majority of the occasional dramatic episodes of inflammation after hylan G-F 20 injection do not seem to be related to crystals. No detrimental lasting results were noted. The absence of post-hylan flares following the first intraarticular injection in this small series suggests that sensitization to or accumulation of hylan G-F 20 or its breakdown products may play an etiologic role in these flares.

To describe therapies with disease modifying antirheumatic drugs (DMARD) and biological agents in patients with early rheumatoid arthritis (RA) who were receiving routine clinical care in 2001 in a private practice of 5 rheumatologists in Nashville, TN, USA. ⋯ After a median duration of 12.1 months of DMARD therapy, almost 90% of patients with recent onset RA took MTX as the anchor drug. More than 60% took MTX as a single DMARD or in combination with traditional DMARD, while 30% took leflunomide, etanercept, or infliximab, usually in combination with MTX.

To determine whether circulating concentrations of the counteradhesive proteins SPARC (secreted protein acidic and rich in cysteine) and thrombospondin-1 (TSP-1) are elevated in scleroderma (systemic sclerosis, SSc). The relationship of these counteradhesive proteins to measures of platelet and endothelial cell activation was examined. ⋯ That circulating SPARC and TSP-1 are elevated in patients with SSc raises the possibility that counteradhesive proteins, which regulate vascular organization and remodeling, might contribute to the pathogenesis of SSc vasculopathy.

To examine the independent effects of chronic regional and widespread pain syndromes on health and functional status after accounting for comorbid chronic fatigue using a co-twin control design. ⋯ Both chronic regional and widespread pain exact debilitating effects on perceived general health, physical functioning, and sleep quality independent of CFS. However, the psychological and psychiatric influence of chronic pain appears closely tied to CFS. Research should examine the additive role of CFS-like illnesses in patients with chronic pain, and its influence on treatment and outcome.
