A patient with hypercalcemia due to primary hyperparathyroidism presented with diplopia that resolved with surgical removal of his parathyroid adenoma and normalization of his serum calcium values. No previous report of this feature of hyperparathyroidism has been reported.

BACKGROUND Using both estimated glomerular filtration rate (eGFR) and proteinuria to classify the severity of chronic kidney disease (CKD) has been proposed. The utility of a staging system incorporating both eGFR and proteinuria for guiding the evaluation of concurrent CKD complications is not known. STUDY DESIGN Cross-sectional analysis. SETTING & PARTICIPANTS 30,528 participants in the U...

Introduction: Brown tumor or lesions resembling giant cell tumor is a rare sequel of hyperparathyroidism and occasionally affect jaw bones. Brown tumor is three times more common in women as compared to men. Mandible is more frequently involved than maxilla. Parathyroidectomy to control HPT is the treatment of choice for brown tumor. Case report: This paper describes a rare case report of brown...

Primary hyperparathyroidism may occur as a part of an inherited syndrome in a combination with pancreatic endocrine tumours and/or pituitary adenoma, which is classified as Multiple Endocrine Neoplasia type 1 (MEN-1). This syndrome is caused by a germline mutation in MEN-1 gene encoding a tumour-suppressor protein, menin. Primary hyperparathyroidism is the most frequent clinical presentation of...

Incidence of primary hyperparathyroidism due to parathyroid carcinoma along with non-medullary thyroid carcinoma is extremely rare. The authors present the unique case of a patient with a 4.3 × 3.1 × 2.5 cm parathyroid carcinoma on the left side, and a 5 mm papillary thyroid microcarcinoma on the right side. The patient was operated thrice because of persistent hyperparathyroidism. The literatu...

THE diagnosis of primary hyperparathyroidism has been classically based upon the demonstration of high plasma calcium and low plasma phosphorus concentrations and an excessive urinary excretion of calcium. In recent years, however, it has become recognized that patients with primary hyperparathyroidism may present with plasma calcium concentrations that are within the normal range (George et al...

Ultrasound is one of the preferred modalities for evaluation of the parathyroid glands. This study was undertaken to determine the accuracy of high resolution ultrasound for secondary hyperparathyroidism in patients with chronic renal failure. From March 2008 to March 2009, ninety-one hemodialysis patients were examined by high resolution ultrasound (14 MHz) of the parathyroid glands in compari...
