| periodic system | The arrangement of the chemical elements in a definite order as indicated by their respective atomic numbers in such a way that groups of elements with similar chemical properties (similar valence shell electron number) are grouped together. See: Mendeleeff's law. (05 Mar 2000) |
| hyperkalaemic periodic paralysis | A form of periodic paralysis in which the serum potassium level is elevated during attacks; onset occurs in infancy, attacks are frequent but relatively mild, and myotonia is often present; autosomal dominant inheritance. (05 Mar 2000) |
| hypokalaemic periodic paralysis | <biochemistry> A rare inherited disorder, affecting men more often than women, characterised by intermittent episodes of muscle weakness or paralysis. One form, known as hypokalaemic periodic paralysis, is an autosomal recessive disorder that is characterised by bouts of muscle weakness (or paralysis) accompanied by low serum potassium levels. Inheritance: autosomal recessive. Incidence: 1 in 100,000. (11 Jan 1998) |
| sodium-responsive periodic paralysis | A form of periodic paralysis in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance. Synonym: sodium-responsive periodic paralysis. (05 Mar 2000) |
| normokalaemic periodic paralysis | A form of periodic paralysis in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance. Synonym: sodium-responsive periodic paralysis. (05 Mar 2000) |
| familial periodic paralysis | <neurology> A rare inherited disorder, affecting men more often than women, characterised by intermittent episodes of muscle weakness or paralysis. One form, known as hypokalaemic periodic paralysis, is an autosomal recessive disorder that is characterised by bouts of muscle weakness (or paralysis) accompanied by low serum potassium levels. Inheritance: autosomal recessive. Incidence: 1 in 100,000. (27 Sep 1997) |
