OBJECTIVE To assess the value of preoperative sestamibi scanning and intraoperative parathyroid hormone (IOPTH) measurement in the treatment of patients with primary hyperparathyroidism due to multiple gland disease (MGD). DESIGN Retrospective medical record review. SETTING Tertiary care academic medical center. PATIENTS The study population comprised 383 consecutive patients who underwen...

Hypercalcemia of malignancy is a common finding typically found in patients with advanced stage cancers. We aimed to provide an updated review on the etiology, pathogenesis, clinical presentation, and management of malignancy-related hypercalcemia. We searched PubMed/Medline, Scopus, Embase, and Web of Science for original articles, case reports, and case series articles focused on hypercalcemi...

We have examined circulating concentrations of a parathyroid hormone-like peptide (PLP) in patients with malignancies and in patients with hyperparathyroidism. The radioimmunoassay employed reacts with synthetic amino-terminal fragments of PLP but not with parathyroid hormone. Elevated plasma PLP concentrations were observed in 50% of patients with malignancy and hypercalcemia and in 15% of nor...

Cancer-induced hypercalcemia (CIH) occurs in 5% to 30% of patients with cancer during the course of their disease, depending on the type of tumor. This review provides information on the pathophysiology and treatment of CIH. Enhanced bone resorption is the primary cause of CIH and the release of tumor-derived mediators induces this increase in osteoclast-mediated resorption. The interactions be...

abstract background: primary hyperparathyroidism is autonomous production of parathyroid hormone. after removal of adenoma, one of the surgeons concern is postoperative hypocalcaemia. there is no precise method to determine if patients have hypocalcaemia postoperatively. the purpose of this study was to determine the relation between parathyroid adenoma weights, postoperative serum calcium and ...

Parathyroid lipoadenomas are a rare and benign variant of parathyroid adenomas that are defined morphologically by an abundance of adipocytes. The clinical manifestations and the laboratory findings are indistinguishable from those of the usual forms of parathyroid adenomas. Unlike parathyroid adenomas, parathyroid lipoadenomas can be functional or nonfunctional. We present a case of a function...

OBJECTIVE It is widely recognized that the diagnosis of parathyroid carcinoma (PC) is often difficult because of the overlap of characteristics between malignant and benign parathyroid tumors, especially at an early stage. Based on the identification of tumor suppressor gene HRPT2/CDC73 and its association with hereditary and sporadic PC, screening of gene mutations and detection of parafibromi...

the coexistence of medullary thyroid carcinoma (mtc), papillary thyroid carcinoma (ptc) and parathyroid adenoma is an uncommon clinical entity. here, we report a case of mtc, ptc, and parathyroid adenoma diagnosed incidentally on a routine physical examination of the neck for the work-up of diabetes. the patient had neither symptoms of hypercalcemia nor those related to mtc and ptc.
