Objective: To determine the relationship of Vitamin D levels with anthropometric measurements at time of peak bone mass. Design/Methods: This was a cross-sectional study involving 90 post-pubertal females between the ages of 16 and 22 years who had bone and fat measurements performed using DEXA scan and computerized tomography, as well as biochemical determinations of 25-hydroxyvitamin D2 and D...

1. A rapid increase in plasma renin activity occurred in dogs after intravenous administration of parathyroid extract. 2. This was not seen after injection of a purer parathormone preparation, or the solution used to dilute the parathyroid extract or calcitonin. 3. A vasoactive compound in parathyroid extract appears to provide the most likely explantation of this effect.

Results Transient, mild but significant decrease of serum calcium levels was observed after surgery in up to a fifth of patients, while severe hypocalcemia was shown in about 5% of patients. The reduction of calcemia was more evident in elderly patients, with a concomitant reduction of albuminemia. In severe hypocalcemia, in addition to these two findings, decrease of parathormone levels was sh...

Fahr's phenomenon is a rare neurological disorder characterized by calcifications of several structurers the human brain, including basal ganglia, dentate nuclei cerebellum, thalamus, and hippocampus. It may exist in an idiopathic form or it can be associated to calcium dysmetabolism due parathormone (PTH) defect signaling. Symptoms span from parkinsonism psychiatric syndromes, ataxia, convulsi...

A patient with multiple basal cell carcinoma syndrome, a symptom complex characteristized by nevoid basal cell carcinomas of the skin, jaw cysts, skeletal abnormalities, and hyporesponsiveness to parathormone is presented. In addition, the patient had a retroperitoneal lymphagiomyoma, a hamartomatous lesion, causing ureteral obstruction. The association of neuroectodermic syndromes and retroper...

The outcome of surgical treatment of primary hyperparathyreoidism (PHP) is largely dependent on the radicality of the operation. This is sometimes difficult due to abnormal location of the glands. The use of intraoperative parathormone assay (IOPTH) and a handheld gamma-ray detector (HGRD) might influence the outcome of treatment. The aim of the study was to assess the feasibility of intraopera...

Objectives: 1.To estimate serum intact parathormone(iPTH) and other biochemical parameters (calcium, inorganic phosphate, urea and creatinine) in chronic renal failure and healthy volunteers. 2. To compare and find out correlation between serum intact parathormone and biochemical parameters in the study group. Methods: For the study of 5 stages of chronic renal failure(CRF) totally 150 patients...
