DISTINCT SYNDROME of calcitriol (1,25-dihyA droxyvitamin D,)-mediated hypercalcemia is seen in patients with Hodgkin's disease and non-Hodgkin's lymphomas (NHL). In addition to hypercalcemia, this syndrome is characterized by intestinal hyperabsorption of calcium, normal serum phosphate levels, the absence of renal phosphate wasting, and increased renal excretion of calcium. Other characteristi...

BACKGROUND Chronic kidney disease (CKD) is a common comorbidity in cats with hypercalcemia, but whether CKD is a risk factor for hypercalcemia is unclear. Hypercalcemia often is diagnosed based on total calcium concentration (tCa), which tends to underestimate the ionized calcium concentration (iCa) in cats. OBJECTIVES Assessment of the performance of tCa for the diagnosis of ionized hypercal...

The authors report a case of hypercalcemia in a 79-year-old woman that led to multiple hospitalizations. The case was challenging because the hypercalcemia was ultimately found to have 2 distinct causes. The patient initially presented with an elevated parathyroid hormone (PTH) level, consistent with primary hyperparathyroidism. She underwent parathyroidectomy and her hypercalcemia resolved in ...

Malignancy-associated hypercalcemia is a common finding among adult malignancies. However, the incidence of malignancy-induced hypercalcemia associated with germ cell tumor among pediatric patients is very rare. We describe a 9-year-old girl with an ovarian dysgerminoma presenting with chronic constipation and hypercalcemia. We review some of the causes of malignancy-associated hypercalcemia de...

The use of statins may have unnatural effects. A 54-year-old woman was admitted to the hospital with an incidental finding of hypercalcemia (10.8 mg/dL). There was no disease other than hyperlipidemia, and the patient had been on a course of atorvastatin calcium 10 mg for 1.5 years. A workup investigation to diagnose the cause of hypercalcemia was completed. The investigation did not reveal any...

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...

Introduction: Hypercalcemia referred as serum calcium level over two standard deviations above the average mean values. Clinical manifestations may be due to hypercalcemia or causal disorder both. disorders can caused by group of illness/abnormalities. Cases Presentation: A-5 year-4 months old girl was taken hospital with chief complaint fatigue and shortness breath. Patient also complained dec...

The stimulation of parathyroid hormone (PTH) secretion by hypocalcemia is reduced when hypocalcemia is preceded by hypercalcemia. The present study investigates whether the duration and degree of hypercalcemia influence the reduced PTH response to hypocalcemia after hypercalcemia. In addition, the implication of the arachidonic acid (AA) signaling pathway in this effect is evaluated. The PTH re...

Severe hypercalcemia is a rare metabolic disorder in pediatric medicine. This report describes a rare case of severe hypercalcemia and its clinical manifestations in a 2-year-old toddler. The radiological findings caused by hypercalcemia and osteolysis were emblematic of the osteolytic lesions. Hypercalcemia led to massive pulmonary alveolar calcification. The hypercalcemia was successfully tre...

Hypercalcemia is defined as a serum calcium concentration that is greater than two standard deviations above the normal mean, which in children may vary with age and sex, reflecting changes in the normal physiology at each developmental stage. Hypercalcemic disorders in children may present with hypotonia, poor feeding, vomiting, constipation, abdominal pain, lethargy, polyuria, dehydration, fa...
