Primary hypokalemic periodic paralysis.

Accidental intravenous bolus infusion of potassium chloride in a young man with hypokalemic periodic paralysis

Hypokalemic periodic paralysis is anautosomal dominantdisease characterized by muscle weakness or paralysis with a matching fall in blood potassium levels. Paralysis attacks often occur in adolescence and are induced by strenuous exercise followed by rest, high carbohydrateor high sodiummeal content, sudden changes in temperature, and even excitement, noise, flashing lights and cold temperature...

BILATERAL SUDDEN SENSORINEURAL HEARING LOSS (SSHL) WITH HYPOKALEMIC PERIODIC PARALYSIS (HPP)

Enhancement of K+ conductance improves in vitro the contraction force of skeletal muscle in hypokalemic periodic paralysis.

An abnormal ratio between Na+ and K+ conductances seems to be the cause for the depolarization and paralysis of skeletal muscle in primary hypokalemic periodic paralysis. Recently we have shown that the "K+ channel opener" cromakalim hyperpolarizes mammalian skeletal muscle fibers. Now we have studied the effects of this drug on the twitch force of muscle biopsies from normal and diseased human...

Rhabdomyolysis following severe hypokalemia caused by familial hypokalemic periodic paralysis

Rhabdomyolysis continues to appear with increasing frequency and represents a medical emergency requiring rapid appropriate treatment. One of the unusual causes of nontraumatic rhabdomyolysis is hypokalemic periodic paralysis without secondary causes. Primary hypokalemic periodic paralysis is a rare genetic disease characterized by episodic attacks of muscle weakness due to decreases in serum p...

[Hypokalemic periodic paralysis. A case report].

Periodic paralysis is a rare disorder that causes episodes of severe muscle weakness that can be confused with other diseases, including epilepsy or myasthenia gravis. Hyperkalemic and hypokalemic paralysis are included within these diseases, the latter being divided into periodic paralysis (familial, thyrotoxic or sporadic) and non-periodic paralysis. In this regard, we present a case of famil...
