title: An autopsy case of infant death due to heat stroke.
abstract: We report an autopsy case of infant death due to heat stroke. On a winter day, a 52-day-old female baby was placed under a Japanese electric foot warmer with a coverlet (kotatsu) on an electric carpet warmer in a heated room at home. After about 5 h, the mother noticed that the baby was unconscious and took her to a hospital. Spontaneous respiration, however, was already absent, and the pupils were dilated. The trunk was hot; body temperature was 41.3 degrees C. The skin of the whole body was dry. Autopsy revealed second-degree burn injuries on the left side of the face and the dorsum of the left hand. Numerous marked petechiae and ecchymoses were found in the thymus (capsule and parenchyma), pleurae (visceral and parietal), pericardial cavity (internal and external surfaces), epicardium, and beneath the serosa at the origin of the aorta. In addition, there was congestion in various organs, edema in the brain and lungs, and hemorrhage in the lungs. Histopathologically, macrophages without hemosiderin granules were present in the alveoli. When the heating conditions at the accident were reproduced experimentally, the temperature in the electric kotatsu warmer rose to 50-60 degrees C. Thus, we concluded that misuse of the electric kotatsu caused heat stroke in this infant.
