Primary hyperparathyroidism, a common endocrine disorder, is traditionally defined by hypercalcemia and elevated levels of parathyroid hormone (PTH). A newer presentation of primary hyperparathyroidism has been described over the past decade, in which PTH is elevated but serum calcium is consistently normal, in the absence of secondary causes of hyperparathyroidism, such as renal disease or vit...

OBJECTIVE To describe the non-classical manifestations and quality of life in patients with primary hyperparathyroidism (PHPT). SUBJECTS AND METHODS We evaluated non-classical manifestations and quality of life of 22 patients with PHPT using the SF-36 questionnaire according to the time since diagnosis. RESULTS In the scores of quality of life, a significant difference was found comparing t...

OBJECTIVE Asymptomatic primary hyperparathyroidism (PHPT) is a common clinical problem. The purpose of this report is to guide the use of diagnostics and management for this condition in clinical practice. PARTICIPANTS Interested professional societies selected representatives for the consensus committee and provided funding for a one-day meeting. A subgroup of this committee set the program ...

 Background: Bilateral neck exploration is the gold standard for parathyroid adenoma localization in primary hyperparathyroidism. But surgeons do not have adequate experience for accurate surgical exploration and new methods are developed for surgery like unilateral exploration and minimally invasive surgery, thus, preoperative localization could reduces time and stress in surgical performance....

The plasma magnesium concentration has been determined in 73 patients with primary hyperparathyroidism. In most patients it lay within the normal range (1.7-2.3 mg./100 ml.), but in five it was less than 1.6 mg./100 ml. These patients had relatively high urinary magnesium outputs, and one of them, studied in greater detail, failed to retain parenterally administered magnesium. Hence hypomagnesa...
