Hypoparathyroidism
MONDO:0001220Hypoparathyroidism is an endocrine disorder in which the parathyroid glands in the neck do not produce enough parathyroid hormone (PTH). Common signs and symptoms include abdominal pain, brittle nails, cataracts, dry hair and skin, muscle cramps, tetany, pain in the face, legs, and feet, seizures, tingling sensation, and weakened tooth enamel (in children). It may be caused by injury to the parathyroid glands (e.g., during surgery). Other causes, include low blood magnesium levels, a side effect of radioactive iodine treatment for hyperthyroidism, metabolic alkalosis, DiGeorge syndrome, and type I polyglandular autoimmune syndrome. The goal of treatment is to restore the calcium and mineral balance in the body.
Also known as: hypoparathyroidism, idiopathic (subtype), parathyroid, underactivity of

Pump delivery of hormone may steady calcium levels in rare disorder
Disease control CompletedThis study tested two ways of delivering synthetic parathyroid hormone (PTH) to people with chronic hypoparathyroidism, a condition where the body doesn't make enough PTH, causing low calcium. Researchers compared using an insulin pump to give steady, small doses versus twice-dai…

Quick hormone test may spot thyroid surgery complication risk
Knowledge-focused CompletedThis study looked at 300 patients who had their thyroid removed to see if a parathyroid hormone (PTH) test right after surgery could predict low calcium levels. The goal was to find a threshold that rules out hypoparathyroidism. Researchers reviewed past medical records to analyz…
