Question: Abstract: It is clear that some synovial inflammation occurs in joints affected by osteoarthritis (OA) and it is well recognized that many patients with OA experience a decrease in pain and joint stiffness following administration of salicylates or other nonsteroidal antiinflammatory drugs (NSAIDs). However, neither the extent to which synovitis contributes to the cartilage breakdown in OA nor the effects of chronic administration of NSAIDs on the natural history of OA in humans is known. Recent studies indicate that several NSAIDs, including salicylates, suppress proteoglycan synthesis in articular cartilage in vitro. The effect on OA cartilage is more marked than that on normal cartilage. Other studies show that salicylate feeding may suppress proteoglycan metabolism in degenerating cartilage in vivo, aggravating the decrease in proteoglycan content caused by the disease itself. However, no effect of salicylates on normal articular cartilage has been observed in vivo. In damaged cartilage the magnitude of NSAID-induced suppression of proteoglycan metabolism appears to be related inversely to the proteoglycan content of the tissue. In addition, the NSAIDs used in treatment of arthritis today may differ with respect to their in vivo effects on articular cartilage metabolism due, in part, to differences between the molar concentrations of these drugs in synovial fluid.

Question: Abstract: Gastrointestinal motor function in patients with primary anorexia nervosa has rarely been investigated. We studied oesophageal motor activity in 30 consecutive patients meeting standard diagnostic criteria for primary anorexia nervosa (Feighner et al; DSM III). Seven were found to suffer from achalasia instead of primary anorexia nervosa, one from diffuse oesophageal spasm and one from severe gastro-oesophageal reflux and upper oesophageal sphincter hypertonicity, while partly non-propulsive and repetitive high amplitude, long duration contractions prevailed in the lower oesophagus of another six. In four patients with oesophageal dysmotility not responding to therapy and in 12 of 15 patients with normal oesophageal manometry, gastric emptying of a semisolid meal was studied. Emptying was normal in only three but markedly delayed in 13 cases (half emptying times 97-330 min, median: 147 min, as compared with 21-119 min, median: 47 min, in 24 healthy controls). In eight patients, the effects of domperidone 10 mg iv and placebo were compared under random double blind conditions. Half emptying times were shortened significantly (p less than 0.01) by domperidone. Conclusions: symptoms of disordered upper gastrointestinal motor activity may be mistaken as indicating primary anorexia nervosa; clinical evaluation of patients with presumed primary anorexia nervosa should rule out the possibility that disordered oesophageal motor activity underlies the symptoms; delayed gastric emptying is a frequent feature in primary anorexia nervosa and might be returned to normal with domperidone.

Answer: Yes


Question: Abstract: Twenty patients were examined by standard radiography and roentgen stereophotogrammetric analysis (RSA) during a two-year period after total hip arthroplasty. Eleven of the acetabular components migrated cranially and three femoral components migrated distally. This migration was most rapid during the first four months after operation. Our findings support the possibility that mechanical loosening is initiated by thermal injury during polymerisation of the cement; the less frequent migration of the metallic femoral component compared with the polyethylene acetabular component may be because the metal acts as a heat sink. Standard radiographs were inadequate for assessment of early mechanical loosening, whereas RSA could reveal migration within four months of the arthroplasty.
