[Epidemiological research on primary hyperparathyroidism. A prospective multicenter study].

Serum calcium determination of 11,588 hospitalized patients during a twelve-month period revealed hypercalcaemia in 74 (0.64%). Further clinical and biochemical investigation established primary hyperparathyroidism in 20 of them (27%), and in 15 (20%) a malignant tumour (with bone metastases in six) as the cause of the hypercalcaemia.
