We report two patients with idiopathic hypoparathyroidism and celiac disease. Both had undergone surgery for cataract previously. The patients presented with tetany in the absence of gastrointestinal complaints. Investigations showed severe hypocalcemia, hypoparathyroidism, flattening of duodenal villi histologically, and diffuse cerebral and basal ganglia calcifications on CT scan. After a gluten-free diet with calcium supplementation, the clinical situation and biochemical values improved.

Calcium is the most abundant mineral in the human body. About 99% of calcium is deposited in the bones in the form of hydroxyapatite and only 1% is located in the intracellular and extracellular fluid. Ionized calcium, which makes up about 50% of the total amount of circulating calcium, is biologically active; the remaining percentage is bound to plasma proteins (40%, of which albumin accounts for 90%, and globulins for 10%), or is in complex with anions (10%) such as citrate, lactate, bicarbonate, phosphate.

Background: Parathyroid carcinoma is a rare and challenging malignancy, often confirmed by histopathological analysis. Due to its rarity, it can present in atypically. We present a case of parathyroid carcinoma with an unusual course of pulmonary metastasis emphasizing the complexities of its diagnosis and management.

Hypercalcemia is a frequently encountered laboratory finding in endocrinology, warranting accurate clinical and laboratory evaluation to identify its cause. While primary hyperparathyroidism and malignancies represent the most common causes, many other etiologies have been described, including some reports of hypercalcemia secondary to adrenal insufficiency. On the contrary, hypoparathyroidism is a relatively common cause of hypocalcemia, often arising as a complication of thyroid surgery.

Purpose: Post-surgical hypoparathyroidism (POSH) is a common complication after total thyroidectomy. This study aims to assess the accuracy of serum and ionized calcium and PTH levels on the first postoperative day (POD-1) to predict postoperative hypocalcemia (PoHC), transient hypoparathyroidism (THPT), and permanent hypoparathyroidism (PtHPT).
Methods: Biochemical parameters and clinical variables were retrospectively analyzed in 200 patients.
