Primary hyperparathyroidism in the seventies. A decade of change?
In an effort to identify new trends in the presentation and treatment of primary hyperparathyroidism, 66 patients treated since 1975 were compared with 100 patients diagnosed and treated from 1948 to 1970. Despite widespread use of multichannel analyzers, the late patients had an insignificant increase in diagnosis while asymptomatic (18 percent versus 9 percent in the early group). Hypertension was the most common presenting complaint in patients seen since 1975, compared with renal disease in patients seen before 1970. Findings of diffuse hyperplasia were more common in the late patients (17 percent versus 3 percent in the early patients). There were no differences in rates of operative complications or persistent postoperative hypercalcemia. In the late series of patients persistent hypercalcemia after surgery for hyperplasia was due to inadequate resection of parathyroid tissue. In the adenoma patients, failure to locate the abnormal parathyroid gland was the cause of operative failure.
