A punched-card diagnostic system is described for use in rheumatological practice. The system is based on pattern recognition and provides a list of both common and rare possible diseases. The system is simple and can be manufactured cheaply, and may be of particular use to family doctors in remote areas of practice. The system has also potential as an educational tool for both undergraduate and postgraduate students of medicine.
A double-blind clinical trial was carried out on 2 parallel groups each of 20 in-and out-patients with classical or definite rheumatoid arthritis, to compare the efficacy and tolerance of proglumetacin, a new non-steroidal anti-inflammatory drug, with naproxen. Each patient received daily either 300 mg proglumetacin or 500 mg naproxen in two divided doses, at meals, over a period of 3 months. The whilst both drugs were effective in the long-term treatment of chronic rheumatoid arthritis, proglumetacin appeared to be somewhat more effective than naproxen in reducing the duration of morning stiffness, the articular inflammation score index, erythrocyte sedimentation rate and the dosage of concomitant basic medication. Few side-effects were reported but 1 of the 2 patients in the naproxen group who developed allergic reactions had to be withdrawn during the first few days of treatment.
The presence of IgE in immune complex-enriched fractions prepared by 3% polyethylene glycol (PEG) precipitation was studied. The dissolved PEG-insoluble fraction was incubated with [125I]anti-IgE antibodies an then precipitated again with 3% PEG. Radioactivity in the washed pellets was taken as indicating IgE present in immune complex form. A calibration curve was constructed using artificially prepared IgE-anti-IgE complexes. The method developed may be useful to detect other components present in immune complex fractions.

Twenty-five patients with juvenile chronic arthritis (JCA) were typed for HLA-A,-G,-C and -DR antigens to establish significant differences between normal controls and patients with adult rheumatoid arthritis (RA). HLA-DR antigens were correlated with subgroups of disease, and with several clinical features and immunological parameters of JCA. The frequency of DRW8 antigen was significantly higher in JCA than in normal adult controls or patients with RA. This significance was even higher in the persistent pauciarticular subgroup. Connections were found between DR antigens and clinical, immunological parameters, and some of them proved to be statistically significant. Results are presented and discussed in detail.
