[Spatial and differential income pattern of households of adolescents and young adults who are victims of maxillofacial injuries resulting from firearm aggression]. / Padrão espacial e diferencial de renda dos domicílios de adolescentes e adultos jovens vítimas de traumatismo maxilofacial por agressão com arma de fogo.

The study investigated the spatial pattern of cases of maxillofacial injury resulting from firearm aggression among teenagers and young adults and analyzed the comparison of income differentials in these areas based on the residence of the victims. This is a cross-sectional study with data from victims attended in three hospitals in Belo Horizonte, State of Minas Gerais, from January 2008 to December 2010. The addresses of the victims were georeferenced by geocoding. Randomness and point density trends were analyzed using Ripley's K function and Kernel maps. The spatial interaction between the homes of adolescents and young adults was verified through the K12 function. Records of 218 cases of assault with a male predominance (89.9%) and young adults (70.6%) were found. Household clusters were distributed on an aggregate basis in the urban space with a confidence level of 99% and similar spatial aggregation levels. The hotspots converged on 7 shantytowns or neighboring regions with higher income population revealing spread of events. Hotspots focused on slums with a history of crimes linked to drug trafficking. The incorporation of space in the dynamics of events showed that the economic condition in isolation did not limit victimization.

Resumo O estudo investigou o padrão espacial dos casos de traumatismo maxilofacial decorrentes de agressão com arma de fogo em adolescentes e adultos jovens a partir do local de domicílio das vítimas e analisou comparativamente os diferenciais de renda dessas áreas. Estudo transversal com dados de vítimas atendidas em três hospitais de Belo Horizonte-MG, entre janeiro de 2008 e dezembro de 2010. Endereços foram georeferenciados por geocodificação. Tendências de aleatoriedade e densidade de pontos foram analisadas por Função K de Ripley e mapas de Kernel. A interação espacial entre os domicílios de adolescentes e adultos jovens foi verificada através da Função K12. Encontrouse registros de 218 casos de agressão com arma de fogo, com predomínio do sexo masculino (89,9%) e adultos jovens (70,6%). Os domicílios se distribuíram de forma agregada no espaço urbano com nível de confiança de 99% e níveis de agregação espacial semelhantes. Os clusters de domicílios convergiram para 7 favelas ou regiões vizinhas com população de maior renda revelando propagação de eventos. Os hotspots se concentraram em favelas com histórico de crimes ligados ao narcotráfico. A incorporação do espaço na dinâmica dos eventos mostrou que a condição econômica isoladamente não limitou a vitimização.

Diagnosis and esthetic functional rehabilitation of a patient with amelogenesis imperfecta.

Amelogenesis imperfecta is a hereditary disease that causes structural anomalies in dental enamel of both the primary and permanent dentition. The anomaly may present a variety of clinical forms and appearances, with its main characteristics being the loss of tooth structure, compromised esthetic appearance, and dental sensitivity. The aim of this study was to present the clinical report of a 16-year-old patient with severely compromised esthetics as a result of amelogenesis imperfecta of the hypocalcified type who was rehabilitated with composite resin and ceramic crowns.
