Racional: Correção de hérnia inguinal é o procedimento mais comum em cirurgia geral, sendo que 80.000 operações são realizadas anualmente na Grã-Bretanha, 100.000 na França e 700.000 nos EUA. Dada à sua alta frequência tem grande impacto, tanto nos aspectos médicos como nos econômicos. Objetivo: Analisar as complicações pós-operatórias imediatas comparando hernioplastia com e sem tela. Método: Ensaio clínico randomizado, com a inclusão de 263 pacientes que foram submetidos à operação de hérnia inguinal, randomizados por tabela de randomização. Os tratamentos foram para o grupo com tela Lichtenstein e ao sem malha técnica de Bassini. Usaram-se envelopes sequencialmente numeradas opacos após terem sido cumpridos os critérios de inclusão. As variáveis analisadas foram: dor pós-operatória, seroma, hematoma, infecção, retorno às atividades normais e recorrência. Resultados: A idade média foi de 55,5 anos; 88% dos pacientes eram mulheres e 12% homens. A dor foi maior nos pacientes operados com tela. Conclusões: O grupo com tela teve menos complicações pós-operatórias imediatas e significativamente mais rápido retorno ao trabalho do que hernioplastia sem tela, sendo esta uma das conclusões mais importantes.

Background: Inguinal hernia repair is the most common procedure in general surgery and 80,000 operations are performed annually in Great Britain, 100,000 in France and 700,000 in the US. Given its high frequency has a major impact, both in the medical and economic aspects. Aim: Analyze the immediate postoperative complications comparing mesh versus non mesh hernioplasty. Method: Randomized control trial, with the enrollment of 263 patients underwent surgery for inguinal hernia randomized by randomization table. Treatment (mesh, Lichtenstein or without mesh, Bassini technique) was assigned using sequentially numbered opaque envelopes having fulfilled the inclusion criteria. The variables analyzed were: postoperative pain, seroma, hematoma, infection, return to normal activities and recurrence. Results: The mean age was 55.5 years, 88% patients were male and 12% female. The pain was higher in patients operated with mesh. Conclusions: The inguinal hernia repair mesh group had less immediate postoperative complications and significantly earlier return to work than hernioplasty without mesh, this being one of the most important conclusions.

The objective of this study was to evaluate the performance, the carcass and meat characteristics of ewes supplemented with magnesium oxide. Eighteen 6-year-old Santa Ines ewes were used in a completely randomized experimental design, where three levels of supplementation (0.0, 0.1 and 0.2% magnesium oxide in the concentrate) were tested, with six replicates. Final weight, weight gain, feed intake and feed conversion were not affected by levels of magnesium supplementation. Hot and cold carcass weights showed linear increasing and quadratic responses, respectively, according to supplementation with magnesium. Carcass measurements such as length, depth, and measures of arm and leg were not affected by supplementation. Depth and width of the longissimus muscle and rib-eye area were not affected; however, marbling and ether extract increased linearly with supplementation. Water loss and color were not affected. Lipid oxidation and shear force were not affected by supplementation, while the myofibrillar fragmentation index showed a quadratic regression. There was a linear decrease in pH with magnesium supplementation. Supplementation with magnesium can improve carcass and meat pH, but can act negatively by increasing the amount of marbling and ether extract of meat.

The 90 % of the bowel obstruction caused by intestinal malrotation occurred in children younger than 1 year, this type of obstruction is very uncommon in adults. This is a male of 31 years old, with history of abdominal pain, vomits and constipation since he was a child. These symptoms were sporadical, he didn't need any surgical treatment. Recently he was admitted in our institution presenting similar symptoms, without remission of them. After imaging and laboratory studies, was performed a surgery, and the intraoperatoty diagnosis was intestinal malrotation type I. The surgical treatment was the Ladd Operation. The postsurgery evolution was good. Discharged 4 days after the surgery. The aim of this article is to present a rare case of intestinal obstruction in adults caused for an intestinal malrotation.

El 90 % de los casos de obstrucción por malrotación intestinal ocurre en niños menores de 1 año de edad, siendo altamente infrecuente en adultos. Un paciente de sexo masculino, de 31 años de edad, con antecedente de episodios de dolor abdominal, vómitos y constipación que alternaban con períodos de normalidad desde la niñez es admitido en el hospital por sintomatología similar, la que no cede. Luego de estudios radiológicos y de laboratorio se decide su intervención quirúrgica con el diagnóstico de obstrucción intestinal. El diagnóstico intraoperatorio realizado fue de malrotación intestinal tipo I, practicándose la operación de Ladd. La evolución del paciente es favorable. La infrecuente presentación de esta patología en adultos es lo que motiva la presentación del caso.

De acordo com o Agrianual (2005), a produção citrícola brasileira é de 17,7 milhões de toneladas ano-1,ocupando aproximadamente 1 milhão de hectares no território brasileiro e, deste total, 810 mil hectares localizam-se no Estado de São Paulo. A maioria dos solos brasileiros, inclusive aqueles onde foram instalados os pomares cítricos, apresenta reação ácida. Esta é, sem dúvida, a principal condição desfavorável dos solos e um dos fatores limitantes da produção em solos tropicais. O presente trabalho teve por objetivo estudar o efeito de diferentes modos de aplicação de calcário e de micronutrientes e analisar, de forma comparativa, os custos destes tratamentos em um pomar de laranjeira. O experimento foi desenvolvido na Fazenda Morumbi, município de Estrela D'Oeste-SP, num Argissolo Vermelho-Amarelo. A variedade de laranjeira utilizada foi a 'Natal', enxertada em limão Cravo, com 6 anos de idade e espaçamento 5 x 8 m. O delineamento experimental foi em parcelas subdivididas, com 3 repetições, com 5 tratamentos principais (sem calcário; a necessidade total de calcário (NC) incorporado; NC sem incorporação; ¹/2 NC no primeiro ano + ¹/2 NC no segundo ano e ¹/3 NC no primeiro ano, + ¹/3 NC no segundo ano, + ¹/3 NC no terceiro ano) e dois tratamentos secundários [micronutrientes via solo (FTE-BR 12: 11,5 % de ZnO e B2O3; 1% CuO; 5,4% de Fe2O3; 5,5% de MnO2; 0,2% de MoO3) e micronutrientes via foliar (sulfato de zinco a 0,5% e ácido bórico a 0,08%)], distribuídos em blocos casualizados. Não houve efeito significativo dos modos de aplicação da calagem e de micronutrientes sobre as variáveis avaliadas (produção, sólidos solúveis totais, acidez total titulável). Para massa média do fruto, o efeito significativo aconteceu apenas no primeiro ano, com a calagem em dose única e sem incorporação, e micronutrientes via solo. Concluiu-se que não houve efeito significativo dos modos de aplicação do calcário e dos micronutrientes para produção e massa média dos frutos da laranjeira 'Natal', e a receita líquida foi positiva em todos os tratamentos, sendo que o tratamento 5 [¹/3 da necessidade total de calcário (NC) no 1º ano + ¹/3 da NC no 2º ano, + ¹/3 da NC no 3º ano] apresentou o melhor valor acumulado (U$ 3.721,85 ha-1).

In agreement with the Institute Fnp (2005), the production Brazilian of citrus is of 17,7 million tons year-1 occupying 1 million of ha approximately in the Brazilian territory and of this total one, 810 thousand ha are located in the State of São Paulo. Most of the Brazilian soils, besides those where the citric orchards were installed, it presents acid reaction. This is, without a doubt, the main unfavorable condition of the soils and one of the factors that harm the production in tropical soils. The present work had the objective to study the effect of different ways of lime application, micronutrients and make a comparative analysis of treatments costs in a orange. The experiment was develop at Morumbi Farm, town country of Estrela D'Oeste, in a Ultisol. The variety of orange used was the 'Natal' incorporated at lemon, with six years old and spaced at 5 x 8 m. The outline was in a subdivided plot, with 3 repetitions, with 5 main treatments [without lime application, lime total need (LT) incorporated; LT without incorporation; ¹/2 LT in the first year + ¹/2 LT in the second year; ¹/3 LT in the first year + ¹/3 LT in the second year + ¹/3 LT in the third year] and 2 secondary treatments [micronutrients in the soil (FTE-BR 12: 11,5% de ZnO e B2O3; 1% CuO; 5,4% de Fe2O3; 5,5% de MnO2; 0,2% de MoO3); micronutrients in the leaves (sulfate of zinc to 0,5% and boric acid a 0,08%)], distributed in randomblocks. There is no significant effect in the ways of application of lime and micronutrients in the evaluated parameters (production, total solid soluble (TSS), total acidy, chemical analysis of the soil); to medium mass of the fruit had a significative effect only in the first year, with the liming in a single dose and without incorporation, and micronutrients in the soil. There was not significant effect of the manners of application of the lime and of the micronutrients for production and medium mass of the fruits of the orange and the liquid income was positive in all of the treatments and the treatment 5 [¹/3 of lime total need (LT) in 1º year + ¹/3 of the LT in 2º year + ¹/3 of the LT in 3º year] presented the best accumulated value (U$ 3721,85 ha-1).
