Tetany

Tetany is a clinical syndrome characterized by pathologically heightened neuromuscular excitability, primarily affecting the peripheral nervous system and skeletal musculature It is most frequently caused by severe hypocalcemia, although hypomagnesemia and acute alkalosis can also trigger the condition by lowering serum ionized calcium concentrations and reducing the threshold for neuronal depolarization Manifestations range from mild sensory disturbances, such as distal or perioral paresthesias...

Tetany is a clinical syndrome characterized by pathologically heightened neuromuscular excitability, primarily affecting the peripheral nervous system and skeletal musculature

It is most frequently caused by severe hypocalcemia, although hypomagnesemia and acute alkalosis can also trigger the condition by lowering serum ionized calcium concentrations and reducing the threshold for neuronal depolarization Manifestations range from mild sensory disturbances, such as distal or perioral paresthesias, to overt involuntary motor phenomena, including painful muscle cramps, carpopedal spasms, laryngospasm, and generalized seizures

Latent forms are clinically unmasked using provocative physical examination maneuvers, specifically Chvostek's sign and Trousseau's sign
