IntroductionTraffic events are one of the five leading causes of mortality in Mexico. Pedestrians are one of the main road users involved in such incidents and have the highest mortality rate, which is regularly analysed in relation to vehicles and pedestrians, but not the built environment. The purpose of this study was to analyse the elements of the road system organisation that influences the mortality rate of pedestrians hit by motor vehicles in the Guadalajara Metropolitan Area.MethodWe designed a case and control study in which the cases were sites where a pedestrian died during 2012. The controls were sites close to where the death occurred, as well as those with road infrastructure characteristics similar to those where the events took place. We obtained the pedestrian data from the death certificates and assessed some of the environmental elements of the road sites. A logistic regression analysis was used to estimate OR; 95% CI.ResultsRoad system factors related with pedestrian mortality in close locations were: the presence of bus stops on intersections in one street or both, and road system features, such as the presence of traffic islands, vehicle flow and pedestrian flow.ConclusionsAccording to the urban network theory and multiple theory, the final elements resulted as risk factors due to a fault in connectivity between the nodes. A temporal analysis of urban features will help urban planners make decisions regarding the safety of pedestrians and other road users.

IntroductionBurns are a problem in public health that occupies the third leading cause of injury in children worldwide.ObjectiveAnalyse the epidemiology of burns in children and adolescents in the Burns Unit of the Guadalajara Civil Hospital Dr Juan I Menchaca.MethodologyThis research is descriptive. Data were obtained through 118 patient clinical records and interviews with their family members from 1 November 2008 to 31 October 2009. The variables studied were: gender, age, injury mechanism, injury agent, degree of burn, place where it happened, place where first medical care was received and time to first medical care after injury.ResultsMale gender was three times as frequent as female gender in burns patients (70 vs 48), and also suffered the most severe injuries. The largest age group was the 0–2 years old (48.3% of cases). In the majority, the mechanism of injury was non-intentional. The most common agents were hot liquids (55.9%) and fire (28.0%). The most frequent locations were injury occurred was home, mainly in the kitchen. In 11.0% of patients receive their first medical care after 3:00.ConclusionsThe groups at highest risk were children under 3 years old and males; the most frequent burning agent were hot liquids; and the events occurred at home.
