Maintenance of physiological levels of intracellular and extracellular calcium is essential for life. Increased intracellular calcium levels are involved in cell death (apoptosis and necrosis) and are associated with positive responses in the Comet assay in vitro. In addition, high calcium and
This paper contains the first demonstration of quantitative changes in the levels of calcitonin-like immunoreactivity in the pituitary. The concentration of calcitonin-like material in lean Zucker rats (?/+) was 0.42 +/- 0.09 ng/mg wet weight of pituitary. The pituitaries of obese rats (fa/fa)
The presence of obesity may confound cholecalciferol dosing in vitamin D-deficient patients owing to potentially decreased bioavailability. The aim of this retrospective study was to evaluate cholecalciferol therapy in vitamin D-deficient, critically ill trauma patients with and Nutrition support in the critically ill patient is challenging but is even more difficult in a morbidly obese patient. This case report chronicles the care of a 6-foot-tall, 256-kg male (body mass index 76.5 kg/m(2)) who spent over a month in the intensive care unit for respiratory failure, sepsis,
In order to investigate mineral and vitamin D metabolism in obese rats with hyperinsulinemia, plasma calcium and vitamin D metabolites were measured in Zucker fa/fa rats. Body weight, plasma insulin, and calcium in fa/fa rats were significantly increased compared to their lean littermates (p less
The etiology of the alterations in calcitonin (CT) secretion and plasma calcium of genetically obese (fa/fa) rats is unknown. In this study, we tested the postulate that there is an early occurrence of abnormalities in CT biosynthesis by thyroid glands of these rodents. Male genetically obese Zucker
Comparison between lean (Fa/?) and obese (fa/fa) young adult male Zucker rat thyroids reveals that obese rats display larger clusters of parafollicular cells than the lean ones with a lesser blood supply. Fa/? thyroid typically shows single or "twin" C cells in follicles; fa/fa parafollicular cells
OBJECTIVE
To report a case of artifactual hypercalcemia in a patient with hyperlipidemia.
METHODS
We present clinical data and laboratory findings in a 33-year-old woman with generalized fatigue, a recent 5-kg weight loss, and a papular rash on the extremities as well as a history of diabetes and
Tiludronate is a new bisphosphonate whose efficacy has already been reported for the prevention of postmenopausal bone loss. We have evaluated its efficacy and tolerance by a dose-finding study in 19 hypercalcemic cancer patients after adequate intravenous (iv) rehydration. Treatment consisted of 3
BACKGROUND
Currently available phosphate binders are associated with either hypercalcemia or high costs, which limit their use in hemodialysis patients. Whether modifying dialysis prescription to intensify small-solute clearance also leads to better phosphate clearance is unknown.
METHODS
Randomized
Bisphosphonates (or diphosphonates) constitute a major advance in the treatment of tumor-associated hypercalcemia and also have the potential to prevent or reverse osteolysis in normocalcemic patients. Available information on adequate therapeutic doses and potential toxicity is, however, very
OBJECTIVE
Bisphosphonates (BPs) effectively treat metastatic bone disease, hypercalcemia, and osteoporosis. BP exposure, however, may be associated with osteonecrosis of the jaw (ONJ). The aim of the present study was to estimate the magnitude of the association between intravenous (IV) BP exposure
BACKGROUND
Guidelines have suggested that obese adults need 2 to 3 times more vitamin D than lean adults to treat vitamin D deficiency, but few studies have evaluated the vitamin D dose response in obese subjects.
OBJECTIVE
The purpose of this study was to characterize the pharmacokinetics of
BACKGROUND
Morbidly obese patients are known to have abnormal calcium metabolism compared with the non-obese, but the clinical significance of this is unknown. Since surgical treatment of obesity may itself cause hyperparathyroidism, it is important to understand the preoperative physiology of these
Obese children are vulnerable to vitamin D deficiency and impaired cardiovascular health; vitamin D replenishment might improve their cardiovascular health.The aims were to determine, in vitamin D-deficient overweight and obese children, whether
