Study conducted in the city of São Paulo from January 2001 to July 2002 with the goal of analyzing the profiles of individuals involved in motorcycle accidents, evaluating the rider's profile, the circumstances of the accidents, injuries, and the use of protective gear. 387 patients needing only traumatic orthopedic treatment were found, between 16 and 44 years of age, of which 354 were males (91.0%). The most common mechanism of trauma involved a collision between the motorcycle and another vehicle (67.0%) at a speed between 12.5-37.5 mph (73.0%) involving less experienced riders (67.0%) between 21 and 24 years of age (45%), and in which 532 (53.9%) lower limb injuries occurred. Of the injuries, 393 (39.8%) were wounds, 314 (31.8%) were bruises and 212 (21.5%) were fractures [foot, 34 (16%); femur, 32 (15.1%); ankle, 27 (12.7%); tibia, 25 (11.8%)]. Recurring accidents were observed in 231 (60.0%) cases and only 6.0% of the riders were not using protective equipment. Increased speed showed a higher rate of fractures when the Mann-Whitney test was applied (p = 0.001). Research on mechanical and traffic engineering, in combination with supervision and awareness-raising of the population, should be considered the most effective methods of prevention.
INTRODUÇÃO: A realização deste trabalho foi motivada pela escassez de artigos encontrados na literatura que estudam o politrauma na infância e na adolescência.. O objetivo é descrever o perfil epidemiológico das lesões traumáticas na infância tratadas num centro de trauma, avaliar os aspectos econômicos relacionados com o gasto hospitalar e o tempo de internação de acordo com o tratamento realizado. MATERIAIS E MÉTODOS: analisamos todos os prontuários do hospital Geral de Pirajussara no período de dezembro de 2005 a dezembro de 2006. Obtivemos 182 pacientes, sendo 71% do sexo masculino e 29% do feminino; 48% brancos e 52% não brancos. RESULTADOS: houve predominância dos indivíduos do sexo masculino com 71% dos pacientes. O mecanismo de trauma mais freqüente foi a queda (36%). A média de dias de internação foi 4,1 dias, com gasto estimado de R$ 649,50 para cada paciente. A taxa de mortalidade foi de 2,74%, sendo o traumatismo crânio-encefálico responsável por 80% da mortalidade e os maus tratos presentes em 40% dos óbitos. CONCLUSÃO: a população pediátrica tem particularidades que a tornam distinta da população adulta em relação à epidemiologia e manejo das lesões.

There is a consensus among researchers that the treatment for Legg-Calvé-Perthes disease, whether conservative or surgical, is always based on the concept of "containment," that is, maintaining the femoral head inside the acetabulum socket throughout the entire evolution of the disease. Thus, the size and shape of the proximal femoral epiphysis should be monitored during the evolution of the disease. Although diagnosis is carried out by conventional radiographies in many medical institutions, this examination does not give us this information. Therefore, it becomes necessary to resort to other examination techniques, such as pneumoarthrography and magnetic resonance imaging. In our institution, we noticed the importance of hip arthrography in Legg-Calvé-Perthes disease from a study carried out by Laredo in 1985 that classified the disease into 5 groups based on the form and size of the femoral head and its position in the labrum. According to this researcher, group III, which he called "hip at premature arthrographic risk," requires action and yields the best results. The researchers have the opinion that dynamic pneumoarthrography is the best method for establishing an ideal position for the femoral head in relation to the acetabulum when surgical treatment is indicated.
ObjectiveThe AO classification for fractures of the long bones in the pediatric population was developed and validated in 2006. However, the complexity of this system has limited its use in clinical practice and few studies in the literature have evaluated its reproducibility and applicability. The present study had the objective of determining the intra and interobserver agreement using the pediatric AO system, among physicians with different levels of experience.MethodsAfter making the sample calculation, 108 consecutive radiographs on long-bone fractures in patients aged 0–16 years, coming from the digital files of the quaternary-level hospital, were selected. The radiographs were classified by five examiners with different levels of experience after prior explanations about the system. A chart containing images from the classification was made available for consultation. The evaluations were made at two different times by each observer. The Fleiss kappa index was used to ascertain the intra and interobserver agreement.ResultsIntraobserver agreement that was at least substantial was obtained for all the items of the classification and it reached excellent levels for all observers in relation to five of the seven items considered. The interobserver evaluation presented excellent levels of agreement in two items, substantial in two items, moderate to substantial in one item and poor to moderate in one item. No influence from the observer's experience was observed with regard to obtaining higher or lower levels of agreement, either in the intraobserver or in the interobserver evaluation.ConclusionsIn this study, the intra and interobserver agreement was considered to be good or excellent for the pediatric AO classification system, for the parameters of bone, segment, paired bone, subsegment, standard and deviation. However, the intra and interobserver agreement was statistically unsatisfactory for the parameter of severity/side of avulsion. The levels of agreement obtained did not depend on the observer's level of experience within pediatric orthopedics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
