The excessive amounts of parathyroid hormone in secondary hyperparathyroidism (SHPTH) is suggested to interfere with normal erythropoiesis.  In SHPTH, during chronic renal failure, due to the impairment of erythropoietin synthesis, this effect is more pronounced.  In the present study the role of secondary hyperparathyroidism in the severity of anemia was evaluated in hemodialysis patients (n=3...

introduction: radio-guided parathyroid surgery along with other minimally invasive surgeries constitutes the main surgical treatment procedures for different kinds of hyperparathyroidism.  in this article we have reported our experience of radio-guided parathyroid surgery using tc-99m sestamibi. methods: ten patients with hyperparathyroidism included in our study. twenty mci of tc-99m sestamibi...

Hyperparathyroidism is a frequent endocrinopathy, often diagnosed at the stage of subclinical hypercalcemia by systematic calcium measurement and advent new parathyroid hormone techniques. Brown tumors represent late-onset, locally aggressive but potentially benign non-metastatic bone complication secondary to an abnormality metabolism within context hyperparathyroidism. It usually late complic...

Primary hyperparathyroidism, a common endocrine disorder, is traditionally defined by hypercalcemia and elevated levels of parathyroid hormone (PTH). A newer presentation of primary hyperparathyroidism has been described over the past decade, in which PTH is elevated but serum calcium is consistently normal, in the absence of secondary causes of hyperparathyroidism, such as renal disease or vit...

The four parathyroid glands, normally located behind the four poles of the thyroid gland, secrete parathyroid hormone (PTH), which regulates extracellular calcium levels. Hyperparathyroidism, which can be primary, secondary, tertiary or quaternary, results in excess production of PTH. Excessive PTH secretion may be due to hyper-function in the glands themselves, in which case it is referred to ...

Brown tumors are expansile osteolytic lesions of bone, occurring in hyperparathyroidism. They occur more commonly in primary hyperparathyroidism, and tend to regress after the removal of parathyroid adenomas [1]. They are much less common in secondary hyperparathyroidism but have been reported [1]. Brown tumors occur most commonly in ribs , mandible, clavicle, and pelvis, and are uncommon in th...

Brown tumors also called as osteoclastomas, are rare nonneoplastic lesions that arise in the setting of primary or secondary hyperparathyroidism. Parathyroid adenomas or hyperplasia constitute the major Brown tumor source in primary hyperparathyroidism while chronic renal failure is the leading cause in secondary hyperparathyroidism. Most of the patients with the diagnosis of primary hyperparat...

Fahrs syndrome is a rare anatomoclinical entity whose main etiology primary or postoperative hypoparathyroidism. It characterized by bilateral and symmetrical intracerebral calcifications, localized in the basal ganglia. Hypoparathyroidism, postoperative, most classic anomaly. Hyperparathyroidism exceptionally reported as cause of Fahr syndrome. We report case 30-year-old woman who presented wi...
