| recurrent tetany | A simple autosomal recessive trait in Scottish terrier dogs, characterised by arching of the back and a stiff-legged gait due to overflexed hindlimbs and abducted forelimbs. Synonym: Scotch cramp. (05 Mar 2000) |
|---|---|
| rheumatic tetany | An acute epidemic form of tetany, of several weeks' duration, occurring chiefly in winter. Synonym: epidemic tetany. (05 Mar 2000) |
| grass tetany | A highly fatal disease of cows and sheep occurring generally during the first two weeks in the spring after the animals have been out on lush pastures; it is characterised by convulsions, hypomagnesaemia, and usually hypocalcaemia. Synonym: wheat pasture poisoning. (05 Mar 2000) |
| phosphate tetany | Tetany due to the ingestion of an excess of alkaline phosphates (Na2HPO4 or K2HPO4); most commonly produced experimentally in animals by the injection of alkaline phosphate, which reduces the ionised calcium of the blood. (05 Mar 2000) |
| postoperative tetany | Parathyroid tetany caused by injury to or excision of the parathyroids during thyroid removal. (05 Mar 2000) |
| hyperventilation tetany | Tetany caused by forced overbreathing, due to a reduction in CO2in the blood. (05 Mar 2000) |
| hypoparathyroid tetany | Tetany due to lack of parathyroid function, spontaneous or following excision of the parathyroid glands. Synonym: hypoparathyroid tetany, parathyroprival tetany, tetania parathyreopriva. (05 Mar 2000) |
| neonatal tetany | Hypocalcaemic tetany occurring in neonates or young infants, due to transient functional hypoparathyroidism in consumption of cow's milk (high phosphorus content). Synonym: myotonia neonatorum, tetania neonatorum, tetanism. (05 Mar 2000) |
| symptomatic tetany | Tetany from any cause in which neuromuscular hyperexcitability are clearly evident, as opposed to latent tetany. Synonym: symptomatic tetany. (05 Mar 2000) |
| duration tetany | A tonic spasm occurring in degenerated muscles upon application of a strong galvanic current. (05 Mar 2000) |
| infantile tetany | Tetany of infants occurring usually in rickets, due to dietary deficiency of vitamin D. (05 Mar 2000) |
| tetany | 1. Hyperexcitability of nerves and muscles due to decrease in concentration of extracellular ionised calcium, which may be associated with such conditions as parathyroid hypofunction, vitamin D deficiency and alkalosis or result from ingestion of alkaline salts, it is characterised by carpopedal spasm, muscular twitching and cramps, laryngospasm with inspiratory stridor, hyperreflexia and choreiform movements. 2. Tetanus. (18 Nov 1997) |
| tetany cataract | A cataract that develops in hypocalcaemia. (05 Mar 2000) |
| tetany of alkalosis | Tetany due to a loss of acid from the body or an increase in alkali, resulting in a reduction of ionised calcium in plasma and body fluids, e.g., hyperventilation tetany (loss of CO2), gastric tetany (loss of HCl by vomiting), or injection or ingestion of excessive amounts of sodium bicarbonate. (05 Mar 2000) |
| transport tetany | An acute disease seen in cattle and sheep during and shortly after shipping; it appears most often in females in advanced pregnancy and is believed to be precipitated by stress, lack of food and water, and perhaps heat. Synonym: railroad disease, railroad sickness. (05 Mar 2000) |
