Parathyroid hormone secretion after operation for primary hyperparathyroidism.

BACKGROUND Primary hyperparathyroidism (pHPT) is associated with a defective regulation of the secretion of parathyroid hormone (PTH). Thus in pHPT, higher than normal calcium concentrations are required to inhibit PTH release. However, it is not known if this defective regulation is normalized by removal of the parathyroid adenoma (i.e., whether the… (More)
