Hypokalemic periodic paralysis(HypoPP) is characterized by an abrupt onset of flaccid paralysis with a clear mentality, but muscles of speech and swallowing are usually spared. We report on three patients who suffered attacks of acute paralysis. After exclusion of central nervous system involvement, the patients showing hypokalemia was diagnosed as hypokalemic periodic paralysis, which was completely reversible on parenteral potassium substitution.

A 5-year-old girl was admitted because of an acute onset of weakness in her extremities. She had experienced a similar episode before but had recovered spontaneously. She had previously been diagnosed with distal renal tubular acidosis(RTA) at the age of 2 months. During the period of acute paralysis, her serum potassium level was 1.8 mmol/L and the muscle enzymes were markedly raised suggesting massive rhabdomyolysis. Although hypokalemia is common in renal tubular acidosis, acute paralytic presentation is uncommon and is rarely described in children. We report a case of distal RTA complicated with hypokalemic paralysis with a brief review of related literatures.

Thyrotoxic periodic paralysis (PP) is the most common acquired form of PP in Asian populations, and its cardinal and biochemical abnormality is hypokalemia. We describe a 39-year-old man who had acute bilateral limb motor weakness and paresthesia, and showed normokalemia during attack. Thyroid studies showed subclinical thyrotoxic Goiter. Control of the hyperthyroidism nearly eliminated his PP. Regardless of normokalemia, our patient might be a case of hypokalemic PP because of improvement from anti-thyroid medication.
