[A severe form of heat stroke in a long-distance runner].

A case of a severe heat stroke is reported in a 30 yr old white man while running a long-distance race. At the time of admission, moderate hyperthermia (40 degrees C) and coma were two major symptoms found at physical examination. Within 24 h, the clinical picture evolved to multiple organ failure with marked rhabdomyolysis, acute renal failure with hyperkalaemia and lactic acidosis.
