Postmenopausal osteoporosis is a disorder characterized by the progressive bone loss induced by estrogen deficiency in postmenopausal women. This imbalance affects calcium–phosphate metabolism and results in secondary hyperparathyroidism. Purariae Radix (PR), the root of P. lobata (Wild.) Ohwi, is one of the earliest medicinal herbs employed in ancient China. PR contains a high quantity of isof...

A 52-year-old woman, a hemodialysis patient, was admitted because of exertional dyspnea. Echocardiography showed left ventricular (LV) dilatation and reduced contraction. Coronary angiography showed no fixed stenosis. She had elevated levels of parathyroid hormone (PTH) as a result of secondary hyperparathyroidism with advanced renal failure. After parathyroidectomy, marked improvement of LV fu...

BACKGROUND Secondary hyperparathyroidism is a frequent complication of chronic renal failure. Patients resistant to pharmacotherapy are candidates for parathyroidectomy. Invasiveness of surgical treatment can be minimized by precise preoperative localization of parathyroid glands. Imaging modalities routinely used for this purpose are ultrasonography and MIBI-Tc99m scintigraphy. CASE REPORT O...

Recently published 'Guidelines for the management of secondary hyperparathyroidism in chronic dialysis patients' by the Japanese Society for Dialysis Therapy advocate that percutaneous ethanol injection into enlarged glands, which has been considered as the only alternative to parathyroidectomy (PTx), should be indicated in patients with a single enlarged parathyroid gland (estimated volume >50...

Cinacalcet hydrochloride (cinacalcet) is a calcimimetic approved for the treatment of secondary hyperparathyroidism in patients with chronic kidney disease (CKD) receiving dialysis and for the treatment of hypercalcaemia in patients with parathyroid carcinoma. Following oral administration, peak plasma concentrations of cinacalcet occur within 2-6 hours. The absolute bioavailability is 20-25%, ...

case presentation: this case illustrated the development of secondary and subsequently tertiary hyperparathyroidism in a 66-year-old man with a history of chronic renal failure. the patient was managed surgically by parathyroid autotransplantation and serial explantation. discussion: refractory hypercalcemia due to autonomous parathyroid tissue following parathyroidectomy can be managed with gr...
