Normocalcemic primary hyperparathyroidism. [PDF]
J Clin Densitom, 2013 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 ...

Normocalcemic Primary Hyperparathyroidism is not innocent as it sounds
Ankara Medical Journal, 2022 INTRODUCTION: Primary hyperparathyroidism (PHPT) is the most common cause of hypercalcemia. A group of patients who were admitted with PHPT and had normal calcium levels with high parathyroid hormone (PTH) levels was defined as normocalcemic PHPT (NPHPT).

Renal Papillary Necrosis Associated With Normocalcemic Primary Hyperparathyroidism. [PDF]
AACE Clin Case Rep, 2021 Renal papillary necrosis (RPN) occurring in primary hyperparathyroidism (PHPT) has not been reported. We present a 50-year-old woman who manifested RPN associated with hypercalciuria and normocalcemic PHPT.The diagnosis of RPN was based on imaging studies (ultrasound and computed tomography [CT] scan).

Appropriate Cutoff for 25OHD Levels in the Diagnosis of Normocalcemic Primary Hyperparathyroidism (NPHPT): A Systematic Review [PDF]
J Endocr Soc, 2021 Introduction: The Fourth International Workshop in 2014 delineated guidelines for the diagnosis of NPHPT which include ruling out secondary causes of hyperparathyroidism, and recommended cutoffs for 25 vitamin D (25OHD) to be ≥20ng/mL.
