Pre-Descemet's endothelial keratoplasty: a simple, Descemet's membrane scoring technique for successful graft preparation.

PURPOSE: Pre-Descemet's endothelial keratoplasty (PDEK) donor tissue preparation involves the intrastromal injection of air to create a type 1 big bubble (BB) and avoidance of the creation of a type 2 BB. The purpose of this study was to design and test a technique to consistently creates a type 1 BB without risk of creating a type 2 BB. METHODS: A prospective matched study with 64 human donor sclerocorneal discs, which were not suitable for corneal transplantation, was conducted. The corneas were divided into two groups, of which 32 were subjected to the standard technique of preparing the PDEK donor tissue (group 1, control) and 32 new technique, where in the donor Descemet's membrane was scored with a Sinskey hook. Frequency of occurrence of different types of BB was compared and statistically analysed. RESULTS: With the standard technique (group 1), type 1 BB occurred in 53.1%, type 2 BB in 34.4% and mixed BB in 12.5% of samples. With the scoring technique (group 2), a type 1 BB occurred in 100% of the samples. No type 2 or mixed BB occurred in any case in group 2. The difference in creation of a type 1BB between the two groups was statistically significant (p=0.00). CONCLUSION: The scoring technique is a simple, inexpensive and reproducible option to consistently achieve a type 1 BB to prepare PDEK graft tissue. The next step would be to study the clinical outcomes of PDEK performed with tissue obtained by the scoring technique.

[Is professional recognition in plastic surgery related to activity in research]. / O reconhecimento profissional na cirurgia plástica está correlacionado com atividade em pesquisa.

OBJECTIVE: To evaluate the relation of medical research, with the participation of prominent plastic surgeon in Congress. METHODS: We reviewed the scientific programs of the last 3 Brazilian Congress of Surgery, were selected 21 Brazilian plástic surgeons invited to serve as panelists or speakers in roundtable sessions in the last 3 congresses (Group 1). We randomly selected and paired by other members (associates) of the Brazilian Society of Plastic Surgery, with no participation in congress as speaker (Group 2). We conducted a search for articles published in journals indexed in Medline, Lilacs and SciELO for all doctors selected during the entire academic career and the last 5 years from March 2007 until March 2012. We assessed the research activity through the simple counting of the number of publications in indexed journals for each professional. The number of publications groups was compared. RESULTS: articles produced throughout career: Group 1- 639 articles (average of 30.42 items each). Group 2- 79 articles (mean 3.95 articles each). Difference between medias: p <0.001. CONCLUSION: The results demonstrate that the Brazilian Society of Plastic Surgery seeking professionals with a greater number of publications and journals of higher impact. This approach encourages new members to pursue a higher qualification, and give security to congressmen, they can rely on the existence of a technical criterion in the choice of speakers.

OBJETIVO: avaliar a relação da atividade médica em pesquisa com a participação de destaque, em congressos, do cirurgião plástico. MÉTODOS: analisamos os programas científicos dos três últimos congressos brasileiros de Cirurgia Plástica. Foram selecionados 21 palestrantes brasileiros convidados como conferencistas ou palestrantes nas sessões de mesa redonda (Grupo 1). Selecionamos aleatoriamente e por pareamento, outros membros (associados ou titulares) da sociedade, mas não palestrantes (Grupo 2). Foi realizada busca de artigos publicados em revistas indexadas ao Medline, Lilacs e SciELO por todos os médicos selecionados, durante toda a carreira acadêmica e de março de 2007 até março de 2012. Avaliamos a atividade em pesquisa através da contagem simples do número de publicações nas revistas indexadas para cada profissional. O número de publicações dos grupos foi comparado. RESULTADOS: artigos produzidos durante toda carreira: Grupo 1 - 639 trabalhos (média de 30,42); Grupo 2 - 79 trabalhos (média de 3,95). Diferença entre as médias: p<0,001. . CONCLUSÃO: os resultados demonstram que a Sociedade Brasileira de Cirurgia Plástica colocou os especialistas com maior numero de publicações e, em revistas de maior impacto como palestrantes em seus congressos. Essa conduta estimula os novos membros a buscar uma maior qualificação e dá segurança aos congressistas, que podem confiar na existência de um critério técnico na escolha dos palestrantes. .

Fraturas nasoetmoideorbitais: experiências de 37 anos do serviço de cirurgia craniofacial do hospital de Cajuru e hospital do trabalhador / Naso-orbitoethmoid fractures: 37-year experience of the craniofacial surgery service of the hospital de Cajuru and hospital do trabalhador

Fractures of the naso-orbitoethmoid complex (NOE) remain one of the most challenging tasks in facial reconstruction and account for 2.1% of facial trauma cases. Clinical analyses of NOE fractures showed that they usually affect the telecanthus and cause deformities that would then require retropositioning of the nasal pyramid. Therefore, computed tomographyis an essential technique for further assessment and to identify bone dislocations and fistulas. Treatment involves reconstruction of the intercanthal distance, nasal projection, and internal orbital structures.

A fratura do complexo nasoetmoideorbital (NEO) permanece como uma das tarefas mais desafiadoras no trauma facial. Corresponde a 2,1% dos casos de trauma de face. Achados clínicos clássicos das fraturas NEOs são telecanto e deformidade com retroposicionamento da pirâmide nasal. O estudo com tomografia computadorizada é imprescindível para determinar detalhes e procurar localizar deslocamentos ósseos e fístulas. O tratamento é direcionado à reconstrução da relação intercantal, da projeção nasal e das estruturas internas da órbita.
