endocrine glands, parathyroid glands, parathyroid hyperplasia involves enlargement of all four parathyroid glands, in the neck, control calcium metabolism, condition produces high levels of calcium, in the blood, hypercalcemia, parathyroid hyperplasia causes, 15% of cases of hyperparathyroidism, leads to elevated levels of calcium, in the blood, hypercalcemia, parathyroid hyperplasia, occur sporadically, a family history, part of three familial, inherited, syndromes, multiple endocrine neoplasia 1, men 1, men 2a, isolated familial hyperparathyroidism, familial syndromes, a mutated gene is inherited in an autosomal dominant fashion, need to get the gene, one parent to develop the condition, in men 1, in the parathyroids, tumors, in the pituitary, pancreas, in men 2a, overactivity, the parathyroids is associated, tumors, in the adrenal gland, thyroid, genetic basis of isolated familial parathyroidism is not yet clear, symptoms of hyperparathyroidism associated, parathyroid hyperplasia, lethargy, nausea, constipation, myalgias, muscle pains, kidney stones, bone fractures, signs of hyperparathyroidism associated, parathyroid hyperplasia, fractures, renal colic, elevated serum calcium, low serum phosphorus, elevated intact pth, elevated serum chloride, low serum bicarbonate, elevated 24-hour urine calcium, low bone mineral density, surgery, preferred treatment, 3 1/2 glands, removed, remaining tissue implanted, in the forearm to regulate calcium levels but allow easy surgical access, hypercalcemia recurs, success rate, surgery, parathyroid hyperplasia is lower than, parathyroid adenoma, persistent, recurrent hypercalcemia occurs, 20%, the time, advanced complications of hyperparathyroidism associated, parathyroid hyperplasia include nephrocalcinosis, osteitis fibrosa cystica, patients, have complications, other endocrine tumors, the multiple endocrine neoplasia syndromes, men 1, includes pancreatic, pituitary tumors, adrenal adenomas, lipomas, men 2a, includes medullary carcinoma, the thyroid, pheochromocytoma, have any symptoms of hypercalcemia, family history of any, the men syndromes, patients, a family history, the men syndromes genetically screened, presence, the defective gene, screened regularly, standard diagnostic methods, endocrine problems, this test is positive.
