Hypercalcemia is ideally detected by the measurement of serum ionised calcium. Because this is not widely available, in common clinical practice "albumin-corrected" calcium values are often utilized. Our study investigated whether the method used to measure serum albumin concentration may
OBJECTIVE
To present a case and to review the relationship between tumor production of parathyroid hormone-related protein (PTHrP) and hypercalcemia in oral squamous cell carcinoma (SCC), with emphasis on tongue cancer.
METHODS
We describe a patient with advanced, locally invasive SCC of the tongue
BACKGROUND
Familial hypocalciuric hypercalcemia (FHH) is a lifelong, benign, inherited condition caused by inactivating mutations in the calcium-sensing receptor (CASR) gene. Both FHH and primary hyperparathyroidism (PHPT) are characterized by elevated P-calcium, normal or elevated
A 34-year-old woman with liver insufficiency due to glycogen storage disease III underwent a living spousal liver transplantation. Soon after the successful operation, moderate hypercalcemia along with hyperbilirubinemia emerged without clarified reasons. The hypercalcemia persisted for over a month
BACKGROUND
Medullary thyroid cancer (MTC) is a calcitonin (Ct)-secreting tumor of the parafollicular or C cells of the thyroid gland. Higher serum Ct levels are associated with larger tumor size, distant metastases, and prognosis. We report herein a case of prostate and multiple bone metastases of
BACKGROUND
Hypercalcemia of malignancy is a serious complication of cancer. The objective of this study was to investigate the efficacy and safety of zoledronic acid, a new-generation bisphosphonate and the most potent inhibitor of bone resorption identified to date, for hypercalcemia of malignancy
Loss-of-function mutations of GNA11, which encodes G-protein subunit α11 (Gα11), a signaling partner for the calcium-sensing receptor (CaSR), result in familial hypocalciuric hypercalcemia type 2 (FHH2). FHH2 is characterized by hypercalcemia, inappropriately normal or raised parathyroid hormone
BACKGROUND
Of the 13 reported cases of hypercalcemia associated with fungal infection, 1 was caused by Cryptococcus neoformans and probably mediated by increased levels of 1,25-dihydroxyvitamin D [1,25(OH)2D]. Eight others were associated with Coccidioides immitis, of which only 2 had measured
Humoral hypercalcemia of malignancy (HHM) is one of the most common metabolic complications associated with cancer. A retrospective study of hypercalcemia in patients with squamous cell carcinoma of the oral cavity was undertaken. All patients were periodically monitored for their serum level of
Purpose: To evaluate the serum level of zonulin, which is an intestinal permeability (IP) biomarker, in primary hyperparathyroidism (PHPT) and to investigate the relationship between zonulin, calcium, and parathormone (PTH)
The differentiation between primary or tertiary (both hypercalcemic) and secondary (normocalcemic) hyperparathyroidism requires the identification of hypercalcemia. Calcium in the blood exists as bound, complexed and ionized fractions. Calcium sensors on parathyroid cells interact only with the
Hypercalcemia is a rare complication of hypervitaminosis A. We report a pediatric patient with cystic fibrosis (CF) and pancreatic insufficiency who was found to have hypervitaminosis A causing hypercalcemia, complicated by nephrocalcinosis and renal impairment. The patient is a 4-year-old girl with
To report a case of severe hypercalcemia, exacerbated by vitamin A supplementation and hydrochlorothiazide, in a patient with primary hyperparathyroidism.Clinical and laboratory findings are presented along with response to Hypercalcemia and leukocytosis are two of the most common paraneoplastic syndromes associated with various malignancies. Of note, concomitant manifestation of hypercalcemia and leukocytosis are occasionally observed in the same cancer patients. However, the relationship between these two
In this paper we describe a patient with polycythemia vera (PV), who presented with hypercalcemia due to a parathyroid adenoma. In November 1999, the patient was admitted to our hospital with meteorism and constipation. Her physical examination revealed plethora and hepatosplenomegaly. Laboratory
