We describe 3 cases of tophaceous gout affecting premenopausal women. The only precipitating factor to be found was the chronic and unnecessary overuse of furosemide, apparently resulting from a psychological profile of anorexia nervosa. Our cases emphasize the need for physicians to look for hidden abuse of diuretics in the presence of gouty arthritis in menstruating women, especially if tophi are noted.

The risk of malignant B cell lymphoma is increased in Sjögren's syndrome (SS). Orbital localization seems infrequent. We report 4 cases of malignant lymphoma (ML) occurring in 4 women aged 47 to 77 years, with primary SS in 3 cases, located to the conjunctiva in 2 cases, the lacrymal gland in 1 case and the eyelid in 1 case. The interval between the diagnosis of SS and orbital ML varied from 6 months to 15 years. All 4 lymphomas were of the B cell type, low histopathologic grade, with monoclonal gammopathy in 1 case. Extraocular lymphoma was initially present in 1 case. ML remained localized in 2 cases with a follow-up of 4 and 6 years. Two patients treated by excisional biopsy alone are in complete remission 3 and 6 years later. The 2 other patients treated with orbital radiotherapy and chemotherapy died rapidly (transformation into a high grade malignancy in 1 case). We conclude that clinical, immunopathologic features, as well as prognosis and treatment of ocular adnexa ML in SS are similar to those of primary ML without SS.

A case of destructive arthropathy of the hip with onset two years after surgical removal of an intracapsular osteoid osteoma of the femoral neck is reported. Coincidental occurrence in the same joint of an osteoid osteoma and a destructive arthropathy of unknown etiology cannot be ruled out. However, another hypothesis which deserves discussion is that self-perpetuating synovitis was triggered by the release of mediators of inflammation due to presence of the osteoid osteoma.

Four patients who developed unilateral reflex sympathetic dystrophy of a lower limb associated with a bout of sciatica due to lumbar disc herniation are reported herein. In two cases, reflex sympathetic dystrophy developed after resolution of the sciatica, whereas the two conditions were concomitant in the two other patients. In all four patients, the diagnosis of reflex sympathetic dystrophy was missed. Surgery to release the root was considered in two cases. The reflex sympathetic dystrophy resolved within 1 to 3 months in every case. In view of the incidences of these two conditions, their concomitant occurrence seems rare. To avoid unwarranted therapeutic procedures, reflex sympathetic dystrophy should be considered in patients with chronic painful manifestations accompanying root involvement.

A young woman with Gaucher's disease experienced acute pain in her right sacroiliac (SI) joint. Although pelvic radiographs and computed tomographic scan showed no significant change in the right SI joint, magnetic resonance imaging demonstrated an area of high signal intensity in the iliac part of the right SI joint, and a periosseous collection of blood. This skeletal location is rarely reported in Gaucher's disease; the mechanism of bone crisis is still controversial and our case suggests the occurrence of a bone infarct.
A case of Calmette-Guérin bacillus (BCG) infection of a knee implant during intravesical BCG-therapy is reported. The course was favorable after replacement of the implant and administration of antituberculous agents. This case of septic osteoarthritis due to the BCG is different from cases of reactive polyarthritis reported after intravesical instillations of BCG. It probably resulted from diffusion of the BCG via the bloodstream.

Bilateral symmetrical polyarthritis occurred in three patients (2 males and 1 female), with no previous history of inflammatory rheumatologic disease, given alpha-interferon for 1 1/2, 7, and 10 months as treatment of chronic non A-non B hepatitis, myelofibrosis, and thrombocytopenia with myeloproliferative disorder, respectively. Joint manifestations developed 1 1/2, 3, and 10 months after initiation of alpha-interferon in a dosage of 3.10(6) U three times a week, 4.5.10(6) U per day, and 8.10(6) U three times a week. Polyarthritis persisted following withdrawal of alpha-interferon in the two last patients of whom one had rheumatoid nodules and positive rheumatoid serology and the other had scleritis, exanthema, and negative rheumatoid serology. Erosive rheumatoid arthritis was diagnosed after 28 months and 12 months, respectively, in two patients who required systemic corticosteroids with antimalarials (1 case) or azathioprine after failure of methotrexate (one case). Follow-up in the third case (12 months) is too short to allow differentiation of systemic lupus erythematosus (ANA: 1/1500 H with anti-DNA antibodies 58 U/ml) and chronic autoimmune hepatitis. Reports of chronic inflammatory rheumatologic disease during alpha interferon therapy are exceedingly few in number. In the cases reported herein, alpha-interferon may have either triggered or revealed the joint disease. To prevent occurrence of this complication, exclusion from alpha-interferon therapy of patients with autoantibodies or a positive history for clinical evidence of immune dysfunction may be considered.
