title: Hypokalemic thyrotoxic periodic paralysis in a Caucasian male with Graves' disease.
abstract: The case of a 34-yr-old Caucasian male with Graves' disease presenting with a flaccid quadriplegia and severe hypokalemia is reported. The weakness was prevalent at the lower extremities and began during nocturnal sleep, after a strenuous physical exertion performed during the day. Correction of hypokalemia promptly reversed the quadriplegia. The occurrence of hypokalemic thyrotoxic periodic paralysis several months after the beginning of thyrotoxic symptoms, and the normal insulin serum levels on admission differentiate this patient from most of the previously reported cases.
