Skateboarding: more dangerous than roller skating or in-line skating.

Objective: To describe the circumstances, severity, and outcomes of skating-related injuries among children admitted to trauma centers.

Design: A cross-sectional comparison of roller skaters (n = 154), in-line skaters (n = 190), and skateboarders (n = 254) aged 5 to 19 years who were hospitalized with injuries.

Setting: Seventy-nine hospitals and pediatric trauma centers participating in the National Pediatric Trauma Registry between October 1988 and April 1997.

Causes and outcomes of pediatric injuries occurring at school.

This study examines the causes and outcomes of injuries occurring at school and highlights the need for injury prevention strategies. Descriptive statistics were applied to data from a national pediatric trauma database on 1,558 K-12 graders injured at school severely enough to require hospitalization. Factors analyzed included age, gender, cause, place, time, injured body regions, use of hospital resources, in-hospital fatality rate, and functional limitations.

Violence: A preventable cause of head injury in children.

Violence is one of the most important and preventable causes of head injury in children. This review discusses the epidemiology of youth violence from previously published reports and from new information obtained from the National Pediatric Trauma Registry. Violence prevention is considered in two categories: primary prevention aimed at the general population, and secondary prevention strategies focused on injured children and adolescents.

Topography of visual and somatosensory projections to the superior colliculus of the golden hamster.

The topography of visual and somatosensory projections to the superior colliculus in the Syrian hamster was studied using electrophysiological techniques. The visual projection to the superficial layers of the colliculus is similar in general topography to that described for other rodents. The magnification of the visual field on the colliculus surface was greatest for nasal visual field.
