BACKGROUND The relationship between the number of parathyroid glands preserved and hypoparathyroidism is not well understood. We sought to determine the number of parathyroid glands that need to be preserved to prevent hypoparathyroidism. METHODS We analyzed 454 patients who underwent total thyroidectomy for papillary thyroid carcinoma. We analyzed the frequency of hypoparathyroidism accordin...
Parathyroid carcinoma (PC) is a very rare endocrine cancer with aggressive behavior, high metastatic potential, and poor prognosis. Surgical resection of affected gland(s) other involved structures the elective therapy. Pre-operative intra-operative differential diagnosis benign parathyroid adenoma remains challenge. The lack clear pre-operative does not allow one, in many cases, to choose corr...
Objective. The brown tumour of hyperparathyroidism is a result of a metabolic disorder caused by primary hyperparathyroidism. Report. We described a case of a 37-year-old female patient presenting bimaxillary intraoral lesions and swelling in the neck. Incisional biopsy of the oral lesion was performed and histopathological examination revealed a central giant cell lesion composed by intense ha...
UNLABELLED Parathyroid scintigraphy and high-resolution ultrasonography are frequently used as preoperative localization procedures in primary hyperparathyroidism. However, when thyroid disease coexists, their diagnostic accuracy is probably abated. DESIGN 56 patients with primary hyperparathyroidism were prospectively evaluated with parathyroid scintigraphy (with either thallium or technetiu...
The effect of magnesium chloride or magnesium sulfate infusion on circulating levels of immunoreactive calcitonin (iCT) was evaluated on nine occasions in three patients with metastatic medullary carcinoma of the thyroid. One patient was normocalcemic and had normal circulating levels of immunoreactive parathyroid hormone (iPTH), one patient was hypocalcemic and had surgical hypoparathyroidism,...
Acute pancreatitis is a severe condition with a high mortality rate and it is most commonly caused by Gallstone ́s Disease and excessive alcohol use [1,2]. Acute pancreatitis caused by hypercalcemia due to primary hyperparathyroidism (PHPT) is very rare [3]. The relationship between acute pancreatitis and hypercalcemia was first reported in 1947, but it was not fully appreciated until 10 years l...
A patient with carcinoma of the right breast and coincidental primary hyperparathyroidism is presented. The distinction between hypercalcemia of malignant and hyperparathyroid origins is based on biochemical analysis and localisation of parathyroid adenoma on a computer tomogram of the neck.
Inactivating mutations of the multiple endocrine neoplasia 1 (MEN1) gene cause MEN1 syndrome, characterized by primary hyperparathyroidism (pHPT), and parathyroid and gastro-entero-pancreatic pituitary tumors. At present, only 14 cases of malignant parathyroid tumor have been associated with the syndrome, with 6 cases carrying an inactivating mutation of the MEN1 gene. The present study present...
