ABSTRACT
ABSTRACT PURPOSE: To investigate whether there is a difference between Marlex(r) and Dynamesh PP-light Marlex(r) meshes, in the abdominal wall defect correction, on rats in contaminated surgical site. METHODS: Twenty-eight Wistar rats were divided into two groups of 14, and four subgroups of seven animals. All subgroups underwent similar surgical procedure. One group received the mesh Marlex(r) and the other Dynamesh PP-light(r) for correction of the defect. Before implanting, the meshes went through a contamination process, on which was used standard solution containing 10 UFC of Escherichia coli. Fragments of the animal's abdominal wall received macroscopic, microscopic and microbiological analysis. RESULTS: There was no statistical significance in the analysis of macroscopic variables. Accentuated inflammatory process was shown in all subgroups. The foreign body type reaction was mild in all subgroups, except Dynamesh(r)-14, which was moderate with no statistical significance. The microbiological analysis of the meshes was also similar between the subgroups. CONCLUSION: There was no difference between the meshes of Marlex(r) and Dynamesh PP-light(r) in the ventral abdominal wall defect correction on rats in contaminated surgical site.

INTRODUÇÃO: O objetivo do presente estudo foi avaliar a influencia da atividade médica em pesquisa, com a exposição que o coloproctologista tem nos congressos da Sociedade Brasileira de Coloproctologia (SBCP). MÉTODOS: Comparamos o número de publicações em revistas indexadas ao Medline e Lilacs de cada palestrante dos últimos cinco congressos da SBCP, com o número de publicações de médicos sócios não palestrantes, selecionados aleatoriamente. A pesquisa incluiu o ano de 1965 até 2005, respeitando o mesmo tempo de formado e estado de atuação profissional. RESULTADOS: Foram selecionados um total de 13 conferencistas e 88 palestrantes dos últimos 5 congressos da SBCP, que foram comparados com 102 médicos sócios não palestrantes da SBCP. Os palestrantes publicaram mais trabalhos científicos que os não palestrantes (p<0,0009), e os conferencistas produziram estatisticamente mais publicações (p<0,0009). Maior visibilidade foi observada em São Paulo, Rio de Janeiro e Minas Gerais (71,8 por cento, 6,5 por cento e 6,5 por cento dos palestrantes respectivamente), e maior atividade científica foi observada entre 20 e 40 anos de atividade profissional. A grande maioria das publicações foi em revistas nacionais, especialmente na revista da SBCP (aproximadamente 45 por cento). CONCLUSÃO: A exposição do médico como convidado nos congressos da SBCP e o volume de produção científica estão correlacionados.
INTRODUCTION: The aim of the present study was to evaluate the influence of medical research with the exposition that the colorectal surgeon has in the Brazilian colorectal society national congress (SBCP). MEHTODS: We selected all the Brazilian presenters from conferences and round tables sessions of the last 5 national congresses. Presenter's number of publications in journals indexed in Medline and Lilacs were compared to non-presenters surgeons randomly selected. The research included years 1965 to 2005. Groups were selected respecting age and state. RESULTS: Thirteen congress participants and 88 presenters were selected and compared with 102 non-presenters from the SBCP. Presenters published significantly more scientific papers than non-presenters surgeons. More visibility were observed in São Paulo, Rio de Janeiro and Minas Gerais state (71,8 percent, 6,5 percent and 6,5 percent of the presenters respectively), and more research activity was observed in doctors graduated 20 to 40 years ago. The vast majority of publications were printed in national journals, especially in the SBCP journal (near 45 percent). CONCLUSION: The doctor exposition as a presenter in the Brazilian National SBCP Congress and publication volume is correlated.
