There are usually four parathyroid glands, each is heavily vascular used. The chief cells synthesize and secrete parathyroid hormone(PTH), which is the major hormone in the control of calcium homeostasis. Hyperparathyroidism can be subdivided into primary, secondary and tertiary. In these conditions, clinical features are heavily dependent on Serum calcium levels. Primary hypothyroidism:- Primary hypothyroidism results from excessive secretion of PTH usually from an adenoma 80?
It is associated with renal stones, Bone pain, and cysts. The raised PTH causes raised plasma calcium and lowered plasma phospholipids. The raised calcium can impairment the function of the proximal tubule and also leads to nephrogenic diabetes insipidus Dehydration can be profound. Peptic ulceration and pancreatitis can occur. Very high levels of calcium can cause short QT interval and severe intractable Cardiac…
