title: Profiling pediatric patients involved in automobile crashes in Japan.
abstract: BACKGROUND
  There is little data concerning the injuries induced by being run over in children.
  
  
  OBJECTIVE
  Characteristics of injuries suffered in children by being run over were investigated.
  
  
  METHODS
  Between January 1998 and December 2007, the medical charts were retrospectively reviewed to investigate characteristics of the injuries in pediatric patients run over by a car. Patients meeting the following criteria were included: (1) age ≤ 12 years old; (2) the patient was struck by an automobile. The subjects were divided into three groups by the mechanisms of injury: (1) run over; (2) carried away; (3) contact.
  
  
  RESULTS
  Twelve patients had been run over, 44 patients were carried away and 44 patients had been hit by a car (contact). The average age in the run over group was the lowest, followed by that in the carried away group and that in the contact group was the highest. The children's coma score and injury severity score were not significantly different among the three groups; however, the average chest abbreviated injury score was the highest in the run over group, followed by that in the carried away group and that in the contact group was the lowest. The average duration of admission and survival rate among three groups, were not significantly different.
  
  
  CONCLUSIONS
  The patients who were injured due to being run over by a car, tended to be younger and to have severe chest injury.
