<prompt> Causes of Hypercalcemia include all of the following exceptMultiple myelomaLytic skeletal metastasisTotal parentral nutritionAcute Pancreatitis  <response>: Answer is D Acute pancreatitis: Acute Pancreatitis is a miscellaneous cause for Hypocalcemia not hypercalcemia. Note that Hypercalcemia may cause Acute Pancreatitis but Acute Pancreatitis causes hypocalcemia Q. Multiple myeloma, Lytic skeletal metastasis and excessive calcium intake from Total Parentral Nutrition are all established causes of Hypercalcemia Causes of Hypercalcemia: Excessive PTH roduction Primary hyperparathyroidism adenoma, hyperplasia, rarely carcinoma Teiary hyperparathyroidism long-term stimulation of PTH secretion in renal insufficiency Ectopic PTH secretion very rare Inactivating mutations in the CaSR FHH Alterations in CaSR function lithium therapy Hypercalcemia of malignancy Overproduction of PTHrP many solid tumors Lytic skeletal metastases breast, myeloma Excessive 1,25OH2D production Granulomatous diseases sarcoidosis, tuberculosis, silicosis Lymphomas Vitamin D intoxication Primary increase in bone resorption Hypehyroidism Immobilization Excessive calcium intake Milk-alkali syndrome Total parenteral nutrition Other causes Endocrine disorders adrenal insufficiency, pheochromocytoma, VIPoma Medications thiazides, vitamin A, antiestrogens CaSR, calcium sensor receptor; FHH, familial hypocalciuric hypercalcemia; PTH, parathyroid hormone; PTHrP, PTH-related peptide.
