The injury epidemiology of cyclists based on a road trauma registry

<p>Abstract</p> <p>Background</p> <p>Bicycle use has increased in some of France's major cities, mainly as a means of transport. Bicycle crashes need to be studied, preferably by type of cycling. Here we conduct a descriptive analysis.</p> <p>Method</p> <p>A road trauma registry has been in use in France since 1996, in a large county around Lyon (the Rhône, population 1.6 million). It covers outpatients, inpatients and fatalities. All injuries are coded using the Abbreviated Injury Scale (AIS). Proxies were used to identify three types of cycling: learning = children (0-10 years old); sports cycling = teenagers and adults injured outside towns; cycling as means of transport = teenagers and adults injured in towns. The study is based on 13,684 cyclist casualties (1996-2008).</p> <p>Results</p> <p>The percentage of cyclists injured in a collision with a motor vehicle was 8% among children, 17% among teenagers and adults injured outside towns, and 31% among those injured in towns. The percentage of serious casualties (MAIS 3+) was 4.5% among children, 10.9% among adults injured outside towns and 7.2% among those injured in towns. Collisions with motor-vehicles lead to more internal injuries than bicycle-only crashes.</p> <p>Conclusion</p> <p>The description indicates that cyclist type is associated with different crash and injury patterns. In particular, cyclists injured in towns (where cycling is increasing) are generally less severely injured than those injured outside towns for both types of crash (bicycle-only crashes and collisions with a motor vehicle). This is probably due to lower speeds in towns, for both cyclists and motor vehicles.</p

Traumatic dental injuries as reported during school hours in Bergen

Aims: To identify existing guidelines for managing traumatic dental injuries (TDIs) in the schools of Bergen, to ascertain the frequency of occurrence of such injuries, and to estimate the need for further information among teachers and school administrators. Material and methods: The study, undertaken among teachers and school administrators of elementary and lower secondary schools in Bergen municipality, was questionnaire-based and included a cross section of staff. The structured short questionnaire included items registering TDIs during 2009, existence of routines or guidelines for managing TDIs, previous relevant training, and request for TDI education or information. The statistical methods included frequency tables and logistic regression analysis. Results: The response rate was 73%. The incidence proportion of TDIs was measured to 0.74% of children at risk, varying according to children's classes (peak at third class: 1.68% of children in the population). No schools had adequate written guidelines for handling TDIs. Previous education on the subject was scarce. In 20 schools, there was no perceived need for TDI-related education or information. The schools’ routines for TDI reporting, who was in charge of the reporting, acquired TDI education and expressed need for TDI information or education, did not influence the number of reported TDI cases. Conclusion: This study has produced reliable information that schools in the municipality of Bergen could improve ways of reporting and managing TDIs. As teachers with skills in handling TDIs could help to improve the prognosis for injured teeth, some types of educational intervention in schools should be launched
