Diverticulopexia no tratamento do divertículo de Zenker Diverticulopexy for the treatment of Zenker's diverticulum
Renato Micelli Lupinacci,Antonio Carlos Pereira Lima,Renato Arioni Lupinacci
Revista do Colégio Brasileiro de Cirurgi?es , 2013,
Abstract: O divertículo de Zenker é um pseudodivertículo que se origina de um defeito muscular na parede posterior da faringe, na área de transi o entre o músculo constritor inferior da faringe e o músculo cricofaringeo. Apesar do avan o das técnicas endoscópicas, o tratamento cirúrgico persiste como o tratamento padr o. Duas técnicas s o possíveis: diverticulectomia (ressec o do divertículo) e a diverticulopexia. As vantagens da diverticulopexia est o ligadas à ausência de anastomose esofágica e suas possíveis complica es: fistulas cervicais, mediastinite, estenose esofágica e infec o de ferida. Em ambas as técnicas a sec o das fibras musculares do músculo cricofaringeo (ou, esfíncter superior do es fago) é fundamental. O objetivo do presente artigo é descrever em detalhes a técnica de diverticulopexia junto ao ligamento pré-vertebral associada à miotomia do músculo cricofaríngeo. Zenker′s diverticulum is a pseudodiverticulum through a muscular defect in the posterior pharyngeal wall at the area between the inferior pharyngeal constrictor muscles of the pharynx and the cricopharyngeus muscle. Although endoscopic techniques have made significant progress, the surgical treatment remains the gold standard. There are two main techniques: diverticulectomy (resection of the diverticulum) and diverticulopexy. The main advantages of diverticulopexy are mostly linked to the absence of an esophageal anatomosis and its possible complications: cervical fistulae, mediastinitis, esophageal stenosis and wound infection, which allows a rapid recover with satisfactory oral intake. The purpose of this article is to describe in details the technique for diverticulopexy to the prevertebral ligament in association with a miotomy of the cricopharyngeus muscle.

Abstract: Assays were done under greenhouse conditions in order to evaluate the effect of pyraclostrobin (0.0375, 0.0750 and 0.150 mL.L-1) and acibenzolar-S-methyl (ASM) (0.025 g.L-1) in common bacterial blight, using leaves of snap beans cultivar Bragan a. These chemicals were sprayed at three different times: five days before; five days before + five days after; and five days after leaf inoculation with an isolate of Xanthomonas axonopodis pv. phaseoli. They were determinate the levels of polyphenoloxidase, peroxidase and total soluble proteins on inoculated and non-inoculated leaves of snap beans sprayed with pyraclostrobin (0.075 g.L-1) and ASM (0.025 g.L-1). All concentration of pyraclostrobin and ASM reduced the area under the disease progress curve (AUDPC) on leaves of snap beans, and the least AUDPC value was observed when this products were sprayed five days before + five days after inoculation. Higher levels of polyphenoloxidase, peroxidase and the total soluble proteins were observed on leaves sprayed with pyraclostrobin or ASM. Ensaios foram conduzidos sob condi es de casa-de-vegeta o para avaliar o efeito de pyraclostrobin (0,0375; 0.0750 e 0,150 mL.L-1) e acibenzolar-S-methyl (ASM) (0.025 g.L-1) sobre o crestamento bacteriano comum, em folhas de feij o-vagem cultivar Bragan a. Os produtos foram pulverizados em três diferentes períodos: cinco dias antes, cinco dias antes + cinco dias após e cinco dias após a inocula o dos folíolos com um isolado de Xanthomonas axonopodis pv. phaseoli. Foram determinados os teores de polifenoloxidase, peroxidase e proteínas solúveis totais em folhas inoculadas e n o-inoculadas de feij o-vagem pulverizadas com pyraclostrobin (0,075 g.L-1) e ASM (0,025 g.L-1). Todas as concentra es de pyraclostrobin e ASM reduziram os valores da área abaixo da curva do progresso da doen a (AUPDC) e o menor valor da AUPDC foi observado para a aplica o dos produtos cinco dias antes + cinco dias após a inocula o. Altos teores de polifenoloxidase, peroxidase e proteínas solúveis totais foram observados nas folhas pulverizadas com pyraclostobin e ASM.

Abstract: Objectives: To discuss the role of bacillus Calmette-Guérin (BCG) immunotherapy in the treatment of superficial bladder cancer after 30 years of clinical experience. Methods: Research on LILACS and PubMed databases, including 31 clinical studies with scientific relevance and importance in the decision-making process. Results: The BCG therapy with induction and maintenance therapy seems to be the best practice in tumors classified as high risk when compared to intravesical chemotherapy. In management of carcinoma in situ, BCG is undoubtedly the therapy of choice, presenting 84.4% of efficacy. As an adjuvant treatment to transurethral resection, there was a 31% reduction in recurrence confirmed in four out of five meta-analyses assessed. The reduction in progression, despite preliminary favorable evidence, still needs further studies to be confirmed. Conclusions: Intravesical BCG is an excellent therapeutic option in cases of carcinoma in situ and it is recommended as an adjuvant treatment in tumors with a high risk of recurrence and progression.

Abstract: species of the genus psidium, like guava and brazilian guava trees, are economically important and have the area of primary genetic diversity in brazil. it was determined the genetic relationships based on aflp marker for accessions of psidium germplasm bank (pgb) of embrapa semiarid to guide improvements and management of genetic resources of the genus. eighty-eight accessions were analyzed, 64 of guava and 24 of brazilian guava, collected in ten brazilian states, adopting for the cluster dendrogram upgma, considering the similarity matrix of jaccard's coefficient of 149 polymorphic aflp bands from 16 combinations of primers ecori and msei. analysis of variance of molecular data was performed considering the variation between and within populations of guava from the ten states. the dendrogram showed good definition, with cophenetic coefficient of 0.94. two major groups were identified: one formed by accessions of guava and other with access to brazilian guava, including some accessions of guava. specific groups were observed in the dendrogram only for individuals guava collected in goias and roraima. these accessions showed similarity ranging from 28 to 98%, suggesting a high genetic variability of them. the variation among accessions was estimated at 0.16 (φst), indicating moderate genetic differentiation among guava populations from the ten states. to increase the genetic variability of the abg studied, it is suggested to collect more hits in the states of goiás and roraima, due to the high degree of similarity among accessions from these states, as well as extensive collections in other brazilian states. crosses among the few accessions of guava which are positioned in the group of brazilian guava were also suggested for the development of interspecific hybrids in the genus psidium.

Revista Portuguesa e Brasileira de Gest?o , 2012,
Abstract: O objetivo deste artigo é desenvolver um índice de disclosure das institui es de Ensino Superior filantrópicas do Brasil (IDIESFB), elaborado a partir da análise de uma amostra composta de 146 entidades cadastradas no Conselho Nacional de Assistência Social (CNAS). Este índice de disclosure das institui es filantrópicas de Ensino Superior foi mensurado a partir das características qualitativas de disclosure, de acordo com a proposi o do estudo de Coy, Dixon e Tower (1993). Os resultados mostram que o índice de disclosure para o caso Brasil, se comparado com os resultados apresentados no estudo de Nelson, Banks e Fischer (2003), está acima do índice de disclosure das universidades canadenses, e próximo ou igual ao das universidades da Inglaterra, País de Gales e Irlanda do Norte, mas bem abaixo do das universidades da Austrália e Nova Zelandia. A pesquisa também apontou que menos de 33% das IESFB realizam disclosure voluntário e que a maioria só apresenta disclosure obrigatório, indicando que s o poucas, ainda, as institui es que se preocupam com a accountability pública além das exigências legais.
