[Major hypercalcemia disclosing sarcoidosis].

Sarcoidosis is exceptionally revealed by major isolated hypercalcemia. To the 4 cases already published, we are adding this one. A review of the literature is presented, focussed on the frequency and characteristic features of the hypercalcemia associated with sarcoidosis, as well as its physiopathology: an overproduction by granulomatous cells of 1-25 dihydroxyvitamin D3 evading the usual regulatory mechanisms.

Corticosteroid injection of the sacroiliac joint in patients with seronegative spondylarthropathy.

Objective: We report our experience with the use of corticosteroid injections into the sacroiliac joint in the treatment of patients with seronegative spondylarthropathy.

Methods: We performed 42 injections, constituting 24 procedures in 22 patients (2 patients had the procedure performed twice).

Results: The response was considered very good or good in 19 of 24 procedures (79.

[Parosteal sarcoma of the radius in the course of etretinate therapy].

A parosteal osteosarcoma of the right radius has developed in a patient treated for a long time by etretinate (total dose: 73 g). If brachial ossifications have been reported to etretinate in 2 cases, they were benign tumours; so coincidence is possible in our case. Nevertheless, a relation between the tumour and the treatment cannot be excluded and justify the report of this observation.

[Study of bone repercussion in 33 cases with anorexia nervosa which 8 with fracture osteoporosis].

A national survey has regrouped 33 cases of anorexia nervosa (AN) with osseous investigations, in particular an absorptiometry of the lumbar spine. 2 groups have been defined: 25 patients without fracture (F-) and 8 patients with osteoporotic fractures (F+), including 5 cases with 12 vertebral fractures and 5 with non vertebral fractures: 31/33 have a low lumbar bone mineral content (BMC). The lumbar BMC of the F+ is significantly lower than the F-: -4.
