Benign rheumatoid nodules.

Nine cases in which subcutaneous rheumatoid nodules were observed in the absence of any evidence of rheumatoid arthritis are recorded. In four of these cases, the nodules appeared during adolescence or adult life, a very rare phenomenon. Synovitis occurred in only one patient, after an interval of 15 years, but it did not persist and other features of rheumatoid arthritis were not present. The siting of the nodules in the sub-cutaneous tissue, the absence of features suggestive of rheumatic fever, necrobiosis lipiodica or fungal infection, and lack of any history of trauma, together with the histological appearance, supported a diagnosis of rheumatoid nodules. In all cases, serological tests for rheumatoid factor were negative but in the only case investigated with immunofluorescent staining, IgG and IgM were demonstrated in the biopsy material. It is important to recognise the fact that these benign nodules do not necessarily indicate that the patient has rheumatoid arthritis, or will develop rheumatoid arthritis in the future. The possible relationship of such nodules to granuloma annulare is discussed.

Naproxen in the treatment of rheumatoid arthritis.

Naproxen, a new nonsteroidal anti-inflammatory analgesic drug was found to be better than placebo and as effective as indomethacin in the treatment of rheumatoid arthritis. The drug was well tolerated, and appears to be a useful alternative to more established medication such as aspirin.

Distribution of yttrium 90 ferric hydroxide colloid and gold 198 colloid after injection into knee.

Thirteen knees were injected with yttrium 90(90Y) ferric hydroxide colloid, and 12 with gold 198(198Au) colloid for treatment of persistent synovitis. Retention in the knee and uptake in lymph nodes and liver were measured by a quantitative scanning technique. There was no significant difference in the retention in the knee of the two different colloids. A tendency towards higher lymph node uptake was observed with 198Au compared with 90y. The inflammatory activity of the knee at the time of treatment may have influenced the subsequent lymph node uptake of 198Au, but not that of the 90Y, nor the overall leakage of either from the knee. 90Yferric hydroxide colloid was retained in the treated knee at least as well as other colloids which have been used for this purpose.

HL-A antigens in Europeans and Maoris with rheumatic fever and rheumatic heart disease.

Using a standard microtoxicity technique of tissue typing, the distribution of tissue antigens in 75 Maoris and 514 European disease-free blood donors was determined. Fifty Maori and 50 Europeans with rheumatic fever or rheumatic heart disease were compared with each control group. Normal Maoris had HL-A3 less frequently than Europeans (P less than .0005). HL-A28 was reduced (P less than .005) and HL-A17 increased in European patients (P less than .0005). In Maori patients there were minor differences in the frequency of HL-A3 and 8, which were increased, and HL-A10, which was diminished.
