Cardiac rupture by blunt chest trauma is commonly seen after motor vehicle accidents and falls; however, it is rarely caused by a blow to the chest. We herein report an autopsy case of a high school boy who sustained severe right ventricular rupture by only one knee kick to the chest during a quarrel. He was hospitalized and developed cardiopulmonary arrest. Emergency surgery was performed, but the patient died. The autopsy revealed no external severe trauma or deformation, but the side wall of the right ventricle contained a large V‐shaped laceration. The other thoracic organs had no injuries. This case illustrates that severe cardiac rupture can occur by only one blow to the chest. Blunt cardiac injuries can occur even if no severe injuries are present on the body surface. We should consider the possibility of severe cardiac injuries regardless of the presence of external injuries. 相似文献

A survey of sex and birth control behavior of 51 male adolescents aged 15–17 was conducted utilizing a structured interview protocol. The purpose of the study was to describe male adolescent birth control behavior incorporating developmental issues, and to interpret the findings in light of what is known about female birth control behavior. Based on research with teenage females, three social influences were examined for their possible impact on male birth control behavior. A new operational definition ofmale effective birth control usage involving the effectiveness of the method and the consistency of its usage was developed. Findings similar to those obtained from research on females suggest that adolescent sexual partners may be the only direct social influence on adolescents' birth control usage. Results indicating differences from research with females suggest that in general: male birth control behavior is primarily self-oriented, males are more likely to be effective contraceptors with casual partners than with girl friends, males are more likely to communicate about sex and birth control with similar age peers than with family members and/or other adults, and that teen males view sex and birth control decisions as female decisions.He also conducts private psychotherapy, specializing in marital and family therapy.
