Abstract
Primary hyperparathyroidism was studied in a well-defined geriatric population of 1129 individuals during a three-month interval. Primary hyperparathyroidism was diagnosed in 1.5%. The diagnosis was based on a morphologic and biochemic basis. From clinical material consisting of 400 patients treated surgically for primary hyperparathyroidism during a ten-year period, 158 patients (38%) above the age of 64 were studied. At the preoperative evaluation, neuromuscular symptoms were present in 80%, renal insufficiency and kidney stones in each 16%, constipation and/or anorexia in 38%. Ten per cent were considered asymptomatic. In 80% the primary hyperparathyroidism was caused by a solitary adenoma. Ninety-four per cent became normocalcemic following the operation. Consistent hypocalcemia requiring vitamin-D treatment occurred in 3%, and 2% had a persisting hypercalcemia or later recurrence. The therapeutic effect on the neuromuscular symptoms, constipation, anorexia, and renal stone formation was considered good or fair in most of the cases. Primary hyperparathyroidism in the elderly occurs with a high prevalence. It can be treated successfully by surgical therapy with a low cost of morbidity, mortality, and medical care.
