Progression of joint damage in early active severe rheumatoid arthritis during 18 months of treatment: comparison of low-dose cyclosporin and parenteral gold

OBJECTIVE: This study compared the progression of joint damage in patients with early active severe rheumatoid arthritis (RA) treated with cyclosporin or parenteral gold. METHODS: In this open, randomized, multicentre study with a blinded radiological endpoint, 375 patients who had suffered from active severe RA for <3 yr were randomized to be treated for 18 months with low-dose cyclosporin or parenteral gold. The groups were stratified with regard to corticosteroid use. Primary efficacy variables were numbers of erosions, erosion score and the Larsen-Dale joint damage score. RESULTS: Joint damage progressed at similar rates in both treatment arms. In both groups, patients receiving corticosteroids had less X-ray progression. Rheumatoid factor positivity, high swollen joint count, high erythrocyte sedimentation rate and pre-existing X-ray abnormalities predicted progression of joint damage. Although numbers of serious adverse events were similar, more gold patients (n = 65) than cyclosporin patients (n = 45) withdrew from study medication because of adverse events. CONCLUSION: Cyclosporin was comparable to parenteral gold in retarding progression of joint damage and was better tolerated in terms of adherence to therapy. The open label design should be kept in mind when assessing this difference.      

Craniosynostosis: diagnostic value of three-dimensional CT reconstruction

Three-dimensional computed tomography (CT) has an important role in determining the presence and extent of congenital and acquired craniofacial deformities. The authors compared the sensitivity and specificity of three-dimensional CT in the detection and characterization of craniosynostosis with that of planar CT and skull radiography. Eighty-two patients with isolated and syndromal synostoses were imaged with CT and three-dimensional CT, and 42 with skull radiography. Three-dimensional CT scan processing was performed by shaded-surface reconstruction, volumetric, and depth-coded methods. Two trained observers read each scan series in a blinded fashion. Diagnostic utility of the images was determined with receiver operating characteristic analysis. The observers ranked three-dimensional shaded images higher than the other types, with three-dimensional volumetric images second and three-dimensional surface images ranked third. Results of this study demonstrate that three-dimensional shaded-surface reconstruction from CT scans is superior to conventional plain radiographs and CT scans in diagnosing craniosynostosis.
