Reye's syndrome.

Reye's syndrome (encephalopathy with fatty infiltration of the viscera) is an acute illness of childhood that produces hepatic dysfunction and metabolic encephalopathy. The disease is fatal in as many as 40% of cases. The cause is unknown. Several environmental agents, particularly salicylates and aflatoxin, have been implicated as possible toxins in this disorder. Treatment is directed at controlling intracranial pressure, reversing metabolic abnormalities and providing intensive supportive care. Normal neurologic function returns in most survivors.
