Recombinant Human rhPTH(1-34) VS Association Alfacalcidol/Hydrochlorothiazide in Severe Primary...
Autosomal Dominant Hypocalcemia OR Primary Hypoparathyroidism Related to Other Cause But Complicated by Hypercalciuria Under TreatmentHypoparathyroidism is a rare condition in which the parathyroid glands fail to produce sufficient amount of parathyroid hormone or the parathyroid hormone produced lacks biologic activity. The most common cause of hypoparathyroidism is damage to or removal of the parathyroid glands due to neck surgery for another condition. Occurrence of hypercalciuria under treatment is a frequent concern in primary hypoparathyroidism, limiting correction of hypocalcemia. Hypoparathyroidism can also be caused by an autoimmune process. In rare cases, hypoparathyroidism may occur as a genetic disorder inherited as an autosomal recessive, autosomal dominant or X-linked recessive trait. The autosomal dominant hypocalcemia (ADH) is mainly caused by heterozygous activating mutations in the CASR gene encoding CaSR). As other severe presentation of primary hypothyroidism, ADH is characterized by the increased risk to develop hypercalciuria and nephrolithiasis. The purpose of the study is to compare two therapeutic approaches in severe hypoparathyroidism in order to limit the risk of nephrocalcinosis and renal failure when attempting to correct hypocalcemia: rhPTH(1-34) vs association of active vitamin D and hydrochlorothiazide. The European Society of Endocrinology Clinical has indeed recently published guidelines for the treatment of chronic hypoparathyroidism in adults. These guidelines suggest considering treatment with a thiazide diuretic In a patient with hypercalciuria and replacement therapy with PTH in patients who do not stably and safely maintain their serum and urinary calcium in the target range.

Does Preoperative Calcium and Calcitriol Decrease Rates of Post Thyroidectomy Hypocalcemia?
HypocalcemiaThyroid DiseasesThe investigators are performing this study to determine if supplementation with calcium and calcitriol (vitamin D) before surgery decreases the rate of hypocalcemia (low calcium) after surgery. Postoperative hypocalcemia (low calcium) is the most common complication after thyroidectomy. Symptoms range from numbness/tingling around the mouth and fingers to severe problems such as low blood pressure, irregular heartbeat, muscle cramps and uncontrollable muscle spasms. The current standard of practice at Lahey for patients undergoing total thyroidectomy is to start Tums 1500mg three times daily and Calcitriol 0.25mcg twice daily immediately after surgery. Also current practice is for each patient to have their calcium and albumin levels checked at 8 hours and 24 hours after surgery. If the corrected calcium level drops below 8.5 or they exhibit symptoms of hypocalcemia the dose of the Tums and Calcitriol are increased per protocol. All patients must also follow up in 3-4 days to have their calcium and albumin levels rechecked. The investigators propose to change the above standard practice at Lahey by making only one change. The investigators wish to start Tums and Calcitriol 5 days before surgery, as opposed to after surgery. This will be the only change to the current standard of care at Lahey. The investigators hypothesize that initiating Tums and Calcitriol supplementation in the preoperative period will decrease the overall rate of postoperative hypocalcemia and its related symptoms. This will possibly decrease length of hospital stay, decrease cost, and prevent any serious complications associated with low calcium.
Use of Prophylactic Steroids in the Prevention of Post-thyroidectomy Hypocalcaemia and Voice Dysfunction...
Thyroid DiseasesHypocalcemia1 moreTotal thyroidectomy for benign surgical pathologies is associated with risks related to temporary hypocalcaemia and vocal quality dysfunction. Dexamethasone, as an anti-inflammatory steroid, has been proposed to have a physiological effect on hypocalcaemia and voice quality. Investigators conducted a double-blinded controlled trial to assess the effect of preoperative dexamethasone on the vocal dysfunction and hypocalcaemia following thyroidectomy

Hypocalcemiathe increased risk of hypocalcemia following total thyroidectomy plus central neck dissection can be minimized by routine administration of oral calcium and vitamin D supplements during the early postoperative period.
Routine Calcium for Preventing Hypocalcemia
Thyroid NeoplasmThe present study investigated the effect of routine calcium and vitamin D supplementation and tried to find the predictors for postoperative hypocalcemia in patients with thyroid cancer.
Phase II Pre-operative Vitamin D Supplementation to Prevent Post-thyroidectomy Hypocalcemia
Thyroid NodulesHypocalcemiaOne of the major side effects of surgery to remove the thyroid gland is transient (lasting for a short time) low calcium levels in the blood, or "hypocalcemia." Low calcium levels can cause symptoms such as numbness around the mouth, tingling or cramping in the hands and feet, severe muscle spasms, inability to breathe, or heart rhythm (heart beat) abnormalities. Severe symptoms are life threatening, so it is important to start the management of these symptoms in the hospital. Treating low calcium levels sometimes require patients to spend a few extra days in the hospital. The human body needs vitamin D to function and stay healthy. Vitamin D helps the body get the calcium needed to make strong bones and teeth. The purpose of this study is to determine if taking vitamin D before surgery to remove the thyroid gland affects whether or not you may have low calcium levels after your surgery and to test the hypothesis that those who are given the Vitamin D before surgery will have decreased hypocalcemia and a shortened hospital stay.
