Abstract
THE clinical manifestations of tetany are striking and include paresthesias, numbness, pain in the distal extremities or periorally, and sensations of tension in the muscles of the hands, feet, face and neck. Sometimes, spasm of the small muscles of the hand impedes fine movements and produces a feeling of weakness or clumsiness. In severe cases twitching, tremors and spasms may involve the carpal, pedal, facial, laryngeal, diaphragmatic and even the neck and trunk muscles. Subclinical or latent tetany may be unrecognized unless signs and symptoms are provoked by maneuvers such as tapping on the facial nerve (Chvostek's sign), ischemia caused . . .
