A well-trained male runner in his late 30s collapsed 10 m before the finish line, nearly completing the 42.1-km marathon course in 3 h, 15 min. He was responsive to pain, agitated, diaphoretic, and unable to walk. The race start temperature was 6 degrees C (43 degrees F) with relative humidity of 99% and the 3-h temperature was 9.5 degrees C (49 degrees F) with a 62% relative humidity. Approxim...

BACKGROUND Exertional heat stroke (EHS) is still a main cause of death in sport. Many of EHS complications could have been prevented if EHS had been recognized and treated early and properly. CASE PRESENTATION We report an unusual case of multiple organ failure caused by EHS due to intensive sportive activities in a hot environment with lack of primary care. A 35-year-old healthy sportive man...

BACKGROUND Exertional heat stroke (EHS) is a life-threatening illness and leads to multi-organ dysfunction including acute kidney injury (AKI). The clinical significance of abnormal electrolytes and renal outcomes in ESH patients has been poorly documented. We aim to exhibit the electrolyte abnormalities, renal outcomes and risk factors of patients with AKI receiving dialysis in EHS. METHODS ...

Rapid and efficient cooling is the most important therapeutic objective in patients with heat stroke (HS). This article reviews the mechanism of action and rationale for the use of dantrolene as a potential supportive cooling method in the treatment of HS. Relevant studies were included to support discussion of the role of dantrolene for the treatment of HS. In some studies dantrolene was shown...

Exercise-associated collapse (EAC) commonly occurs after the completion of endurance running events. EAC is a collapse in conscious athletes who are unable to stand or walk unaided as a result of light headedness, faintness and dizziness or syncope causing a collapse that occurs after completion of an exertional event. Although EAC is perhaps the most common aetiology confronted by the medical ...

HEAT AND HYDRATION MAY NOT BE THE FIRST CONSIDERATIONS OF TOURNAMENT DIRECTORS, COACHES, AND ATHLETES, WHEN PREPARING FOR TENNIS. HOWEVER, HEALTH RISKS AND PERFORMANCE DECREMENTS ARE ASSOCIATED WITH BOTH. THE DEMANDS OF TENNIS, PARTICULARLY DURING MULTIDAY TOURNAMENTS, PREDISPOSE PLAYERS TO INCREASED CORE BODY TEMPERATURE AND LARGE FLUID LOSSES. THIS COMBINATION OF FACTORS CAN LEAD TO DECREASED...
