HypoparathyroidismHypomagnesemia with secondary hypocalcemia: Hypomagnesemia with secondary hypocalcemia (HSH) is an autosomal recessive genetic disorder affecting intestinal magnesium absorption. Decreased intestinal magnesium reabsorption and the resulting decrease in serum magnesium levels is believed to cause lowered parathyroid hormone (PTH) output by the parathyroid gland.Parathyroid hormone family: The parathyroid hormone family is a family of structurally and functionally related proteins. Parathyroid hormone (PTH) is a polypeptidic hormone primarily involved in calcium metabolism.Sestamibi parathyroid scintigraphyParathyroiditis: Parathyroiditis is a condition involving inflammation of the parathyroid gland.ThyroidectomyThymus transplantationTeriparatideMethyclothiazideAutoimmune polyendocrine syndrome type 2Phosphorus deficiency: Phosphorus deficiency is a plant disorder associated with insufficient supply of phosphorus. Phosphorus refers here to salts of phosphates (PO43−), monohydrogen phosphate (HPO42−), and dihydrogen phosphate (H2PO4−).Paroxysmal kinesigenic choreoathetosis: Paroxysmal kinesigenic choreathetosis (PKC) also called Paroxysmal Kinesigenic Dyskinesia (PKD) is a hyperkinetic movement disorder characterized by attacks of involuntary movements, which are triggered by sudden voluntary movements. The number of attacks can increase during puberty and decrease in a person’s 20s to 30s.HyperparathyroidismVitamin DFamilial hypocalciuric hypercalcemiaCalcium signaling: Calcium ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.DihydrotachysterolVocal cord paresisHormone replacement therapy (menopause)Paroxysmal dyskinesia: The paroxysmal dyskinesias (PD) are a group of movement disorders characterized by attacks of hyperkinesia with intact consciousness.Blueprints Neurolgy, 2nd ed.Amorphous calcium carbonate: Amorphous calcium carbonate (ACC) is the amorphous and least stable polymorph of calcium carbonate. ACC is monohydrate and is so unstable under normal conditions that aside from several specialized organisms it is not found naturally.Hyperkalemia
