To determine the effect of ultrasound guided injection in recalcitrant idiopathic plantar fasciitis. ⋯ Ultrasound allows for confirmation of the clinical diagnosis and ultrasound guided injection produces a good clinical response when unguided injection is unsuccessful. The technique is quick, inexpensive, and entails no radiation exposure.

To determine whether induced mast cell activation/degranulation in rheumatoid synovial explants modulates the production of prostaglandin E (PGE2), and the matrix metalloproteinases (MMPs) collagenase 1, gelatinase A, and stromelysin 1. ⋯ MC degranulation induced artificially in rheumatoid synovial explant cultures consistently resulted in an increased production of PGE2 but had variable effects on the quantification of released collagenase 1, gelatinase A, and stromelysin 1. Such observations support the concept that activated synovial MCs within their native environment stimulate the production of non-MC derived PGE2 and may contribute to the regulation and processing of specific MMPs; both aspects represent important components of the inflammatory and degradative processes of the rheumatoid lesion.

Reactive joint complications triggered by salmonella gastroenteritis are increasingly reported, but the outcome and long term prognosis of the patients is incompletely known. This study looked at the prognosis of salmonella arthritis in patients hospitalised in 1970-1986. ⋯ Joint symptoms are common after reactive salmonella arthritis. HLA-B27 contributes to the severity of acute disease and to the late prognosis.

To determine concentrations of chondroitin sulphate (CS) and keratan sulphate (KS) epitopes, glycosaminoglycans (GAGs) and hyaluronan (HA) in knee synovial fluid (SF) from normal subjects and patients with osteoarthritis (OA) or rheumatoid arthritis (RA), to test whether these variables may be used as markers of the OA process. ⋯ Changed concentrations of SF CS and KS can be detected in OA with a profile that differs from that seen in RA. Clinical subgrouping and local joint inflammation may influence these measures, supporting different pathogenesis within OA subgroups and requirement for careful patient characterisation in SF studies.

To assess the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) for low back pain. ⋯ There are flaws in the design of most studies. The pooled odds ratio must be interpreted with caution because the trials at issue, including the high quality trials, did not use identical outcome measures. The results of the 26 randomised trials that have been carried out to date, suggest that NSAIDs might be effective for short-term symptomatic relief in patients with uncomplicated low back pain, but are less effective or ineffective in patients with low back pain with sciatica and patients with sciatica with nerve root symptoms.
