hypoparathyroidism/phosphatase

Recently, a gain of function variant C1858T of the lymphoid-specific protein tyrosine phosphatase non-receptor (LYP, PTPN22) gene has been reported to be associated with several autoimmune disorders including Graves' disease, type 1 diabetes, rheumatoid arthritis and vitiligo. The present study was

Nonsurgical hypoparathyroidism (Ns-HypoPT) and pseudohypoparathyroidism (PHP) are both rare diseases, characterized by hypocalcemia. In Ns-HypoPT, PTH levels are low, whereas patients with PHP often have very high levels due to receptor-insensitivity to PTH (PTH-resistance). Accordingly, we

BACKGROUND Hypercalcemia of immobilization, while rare, may occur in adolescent boys after fracture. Although not fully understood, the mechanism appears to be related to bone turnover uncoupling, in part mediated by upregulation of RANKL. Animal studies suggest that parathyroidectomy suppresses

The combination of poor growth and parathyroid and mineral disorders complicates the diagnosis of renal bone disease in children with chronic renal insufficiency (CRI), and the role of dual X-ray absorptiometry (DXA) is unclear. We aimed to examine the role of DXA in assessing variation in

A case is reported of a patient, aged 20, with idiopathic hypoparathyroidism, manifested with the picture of epilepsy with a long treatment with antiepileptic remedies. Two years after the initiation of the antiepilertic treatment, severe skeleton disturbances occurred with manifested osteoporosis

OBJECTIVE This study aimed to evaluate whether a pre-operative elevated serum alkaline phosphatase level is a potential predictor of post-operative hypocalcaemia after total thyroidectomy. METHODS Data was retrospectively collected from the case notes of patients who had undergone total

In addition to the well-documented hyporesponsiveness of the kidney, resistance to parathyroid hormone (PTH) has been postulated for bone in pseudohypoparathyroidism type I (PHP). In some of these patients reduced bone density and even frank osteitis fibrosa suggest osteoclastic overactivity. To

Bisphosphonate treatment for severe Paget's disease leads to hypocalcemia followed by a secondary hyperparathyroid response to restore normocalcemia. A case is presented of a 60-year-old woman with polyostotic Paget's disease and postsurgical hypoparathyroidism. In 1993 her Paget's disease--alkaline

For assessing the risk of adverse complications of surgery the group of 130 patients with post-operational hypoparathyroidism was analysed. Surgical hypoparathyroidism has been diagnosed in 51% of operated on thyroid gland patients. Laryngeal nerves have been damaged in 46.6% of patients. The injury

Five patients with chronic post-operative hypoparathyroidism were treated with 450 microgram/day 5,6-trans-25-hydroxyvitamin D3 (5,6-trans-25OHD3) for 14 days, and the treatment was continued with 150 microgram/day for one year. At the end of this period the patients received 450 microgram/day

A 17 year old man with longstanding hypocalcemia and hyperphosphatemia presented with incapacitating bone pain and progressive weakness nad bowing of the legs. The serum abnormalities were due to idiopathic hypoparathyroidism as evidenced by a decreased serum concentration of parathyroid hormone and

Vitamin D3 administered to patients with postoperative hypoparathyroidism increases calcium absorption from the gut and calcium blood levels but leads to hypercalciuria and may produce renal lithiasis. Thiazides decrease calcium excretion with the urine. Therefore, an effect of combined therapy with

Hypoparathyroidism is genetically heterogeneous and characterized by low plasma calcium and parathyroid hormone (PTH) concentrations. X-linked hypoparathyroidism (XLHPT) in two American families, is associated with interstitial deletion-insertions involving deletions of chromosome Xq27.1 downstream

BACKGROUND Hutchinson-Gilford progeria syndrome is a rare genetic disorder. It is reported to be present in one in eight million and is characterized by severe growth failure, early loss of hair, lipodystrophy, scleroderma, decreased joint mobility, osteolysis, early atherosclerosis and facial
