Cardiac dysfunction in a patient with familial 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...

Thyrotoxic periodic paralysis in a Turkish male; the recurrence of the attack after radioiodine treatment.

Thyrotoxic hypokalemic periodic paralysis (THPP) is a rare complication of hyperthyroidism and an uncommon form of hypokalemic periodic paralysis. Its differentiation of more common forms of periodic paralysis is important because aggressive treatment can place the patient at risk for rebound hyperkalemia. Treatment of the underlying thyroid dysfunction cures the muscle symptoms. Here we descri...

Thyrotoxic hypokalemic paralysis: a case report

Transient periodical muscle paralysis is an important neurological presentation. Thyrotoxic hypokalemic paralysis is an uncommon type of thyrotoxic paralysis. Except for the findings specifically caused by the subtle hyperthyroid state the clinical and biochemical features of thyrotoxic hypokalemic paralysis are identical to those of familial periodic paralysis. In this article, a case of a 26 ...

Sodium channelopathies in skeletal muscle and brain

Ion channel disorders are rare inherited diseases providing interesting models to study dysfunction of excitability in vivo and in vitro. The first socalled ‘channelopathies’ identified were skeletal muscle diseases, the myotonias and hyperkalemic periodic paralysis (HyperPP), which are sodium or chloride channel disorders. Within the last 5–10 years, complementary genetic and electrophysiologi...
