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...

background secondary hyperparathyroidism (shpt) is a prevalent disorder in patients with chronic kidney disease. it is proffered that there is a contradictory relation between serum level of vitamin c and parathyroid hormone (pth) in hemodialysis patients with secondary hyperparathyroidism. objectives the goal of this study was to assess the effects of the supplemental vitamin c on parathyroid ...

Objective- To determine the prevalence of nutritional secondary hyperparathyroidism (NSH) in companion and stray cats of Ahvaz.   Design- Clinical study. Animals- 80 cats (companion=40 and stray=40) Procedures- This survey was accomplished during a two-year period and based on clinical, radiographic and laboratory findings between 2005 and 2007. The studied cats were divided into two gener...

The four parathyroid glands, normally located behind the four poles of the thyroid gland, secrete parathyroid hormone (PTH), which regulates extracellular calcium levels. Hyperparathyroidism, which can be primary, secondary, tertiary or quaternary, results in excess production of PTH. Excessive PTH secretion may be due to hyper-function in the glands themselves, in which case it is referred to ...

the excessive amounts of parathyroid hormone in secondary hyperparathyroidism (shpth) is suggested to interfere with normal erythropoiesis.  in shpth, during chronic renal failure, due to the impairment of erythropoietin synthesis, this effect is more pronounced.  in the present study the role of secondary hyperparathyroidism in the severity of anemia was evaluated in hemodialysis patients (n=3...
