Recurrent episodes of arthritis in thalassemia minor.

Recurrent episodes of seronegative asymmetrical arthritis usually lasting less than a week have been observed in 4 patients with beta thalassemia minor. In one case, irreversible joint damage of a wrist joint occurred 14 years after the onset of the rheumatism. Studies of the synovial fluid and synovial membrane performed in 2 cases revealed signs of moderate inflammation.

[Sacroiliac changes, HLA-B27 negative, in primary hyperparathyroidism and osteomalacia].

Radiological sacroiliac (SI) changes were found in 3 patients, 2 with primary hyperparathyroidism (1 also with associated chondrocalcinosis) and 1 with osteomalacia. Osteomalacia was due to celiac disease. None of the 3 patients, all females, had a history of psoriasis, urethritis, iritis or chronic colitis.
