Thyrotoxic Periodic Paralysis: An Update

Thyrotoxic periodic paralysis.

Periodic flaccid paralysis of skeletal muscle occurring in a thyrotoxic patient, an unusual and dramatic event, is seen predominantly in Oriental men. It is important to remember the clinical association between periodic paralysis and thyrotoxicosis.

Thyrotoxic Periodic Paralysis: Clinical Challenges

Thyrotoxic periodic paralysis (TPP), a disorder most commonly seen in Asian men, is characterized by abrupt onset of hypokalemia and paralysis. The condition primarily affects the lower extremities and is secondary to thyrotoxicosis. The underlying hyperthyroidism is often subtle causing difficulty in early diagnosis. Factors like high-carbohydrate meal exercise, steroid, and stress can precipi...

[Thyrotoxic hypokalemic periodic paralysis. A case report].

Thyrotoxic hypokalemic periodic paralysis is an uncommon complication of thyrotoxicosis, characterized by attacks of generalized muscular weakness associated with hypokalemia in patients with hyperthyroidism, most frequently with Graves-Basedow disease. Treatment with antithyroid drugs and potassium supplements reversed the symptoms and the episodes of acute muscular weakness did not reappear.

Thyrotoxic periodic paralysis induced by pulse methylprednisolone.

We present a young Thai man who developed acute flaccid paralysis after receiving pulse methylprednisolone for chronic inflammatory demyelinating polyneuropathy. Hypokalemia from intracellular shift was confirmed by calculation of transtubular potassium gradient (TTKG). His muscle strength and serum potassium fully recovered with a small amount of potassium replacement. Graves' disease was subs...
