Pseudohypoparathyroidism: A Variation on the Theme of Hypoparathyroidism
نویسندگان
چکیده
Pseudohypoparathyroidism is characterized by an inability of the body to respond appropriately to parathyroid hormone (PTH), the principal hormone that regulates calcium and phosphorous levels in the body. PTH is made by the parathyroid glands in the neck. There are usually four parathyroid glands, but we probably only need one or two of the glands. PTH is missing, or too low, in patients with hypoparathyroidism. Therefore, the fundamental difference between hypoparathyroidism and pseudohypoparathyroidism is that PTH is absent in hypoparathyroidism, but the body will respond to it; and PTH is plentiful in pseudohypoparathyroidism, but the body cannot respond to it!

Effects of active vitamin D3 and parathyroid hormone on the serum osteocalcin in idiopathic hypoparathyroidism and pseudohypoparathyroidism.
Serum osteocalcin was measured in patients with idiopathic hypoparathyroidism or pseudohypoparathyroidism, before or during the treatment with active vitamin D3 (1,25(OH)2D3 or 1 alpha OHD3). Serum osteocalcin and plasma 1,25(OH)2D were decreased in 11 patients with idiopathic hypoparathyroidism before treatment (2.8 +/- 1.27 ng/ml, P less than 0.001 and 14.3 +/- 4.27 pg/ml, P less than 0.001, ...
متن کاملPseudohypoparathyroidism: defective excretion of 3',5'-AMP in response to parathyroid hormone.
Urinary excretion of cyclic adenosine 3',5'-monophosphate (3',5'-AMP) was tested in normal subjects and patients with pseudohypoparathyroidism, idiopathic hypoparathyroidism, surgical hypoparathyroidism, and pseudopseudohypoparathyroidism under basal conditions and after a 15 min infusion of purified parathyroid hormone. Basal excretion of the nucleotide was less than normal in the patients wit...
متن کاملPseudohypoparathyroidism as a rare cause of bilateral slipped capital femoral epiphysis
Pseudohypoparathyroidism (PHP) type 1b is a rare childhood disorder characterized by renal resistance to parathyroid hormone (PTH) resulting in biochemical hypoparathyroidism but with skeletal sensitivity to PTH. We describe a patient with PHP type 1b who we believe is one of the youngest reported patients with bilateral slipped capital femoral epiphyses (SCFE).

The Neurology and Medical Departments of the Detroit Receiving Hospital have recently made clinical and electroencephalographic (E.E.G.) studies of two patients in a family in which several members appear to have either pseudohypoparathyroidism or pseudo-pseudohypoparathyroidism. The findings were of sufficient interest to prompt us to review this subject and to present our findings since the n...
