New experimental model for training in videosurgery Novo modelo experimental para treinamento em videocirurgia

PURPOSE: To develop a new experimental model of lower cost for training in videosurgery. METHODS: This project was performed at the Nucleus of Experimental Surgery of the Bahiana School of Medicine and Public Health, based on previous models described in the literature and under the supervision of the full professor of Operative Technique and Experimental Surgery II. It was made a model cube-shaped, made of wood, with holes distributed in various locations, rubber stoppers for the holes and lined externally with carpet, and internally with laminate. RESULTS: The new experimental model is of low cost and reproduces quite faithfully several videosurgical procedures. CONCLUSION: Medical schools interested in the subject may adopt the new model for training in videosurgery without the need of high costs for making and using these models.<br>OBJETIVO: Desenvolver um novo modelo experimental de baixo custo para treinamento em videocirurgia MÉTODOS: Este projeto foi conduzido no Núcleo de Cirurgia Experimental da Escola Bahiana de Medicina e Saúde Pública, baseado em modelos prévios descritos na literatura e sob a supervisão do professor titular de Técnica Operatória e Cirurgia Experimental II.

RESULTADOS: O novo modelo experimental desenvolvido é de baixo custo e reproduz de forma bastante fiel diversos procedimentos videocirúrgicos. CONCLUSÃO: Faculdades médicas interessadas no tema poderão adotar o novo modelo para o treinamento em videocirurgia sem que sejam necessários gastos elevados para a confecção e o uso desses modelos

Surgical treatment of ruptured intracranial aneurysms: Timing of treatment and outcome

Background: Patients with ruptured intracranial aneurysm should be treated as early as possible, ideally in the first three days post-hemorrhage. However, in countries like Brazil, these patients are usually not admitted to hospital during this period, creating controversies about ideal timing for surgery. Objective: This study evaluated associations between the timing of treatment and the outcomes of patients submitted to clipping of ruptured intracranial aneurysms. Methods: A retrospective investigation about 218 patients, with 251 ruptured aneurysms, submitted to surgery for clipping was conducted. All patients were treated on the day of admission. Regarding the timing of treatment post-hemorrhage, patients were divided into early surgery, treatment on days 1 or 2; intermediate surgery, on days 3–10; and late surgery, >10 days. The grade of subarachnoid hemorrhage on admission was assessed by Hunt and Hess scale. Outcomes on discharge were investigated using the modified Rankin scale and mortality rate. Results: In 102 patients admitted with good clinical grade, 19 showed poor outcomes (mortality rate: 6.8%), while, in 86 patients admitted with poor clinical grade, 50 showed poor outcomes (mortality rate: 27.9%). No statistically significant relationships were verified between the timing of surgery and a poor outcome and mortality, even classifying patients according to aneurysm location and Hunt Hess scale. Conclusion: No statistically significant associations among mortality or poor outcome and timing for surgery were demonstrated. Considering the risks of re-bleeding and hospital stay, the surgical clipping should be considerate as soon as possible in patients with ruptured aneurysms.

Cottonseed Oil in Diets for Broilers in the Pre-Starter and Starter Phases.

The objective of this study was to evaluate the effect of different levels of crude cottonseed oil in isoenergetic diets, with or without supplementation of ferrous sulfate, on performance variables, relative weight of organs, and blood parameters of broilers, and on the economic viability of diets in the periods from 1 to 7 and 1 to 21 days of age. A total of 600 male birds of the Ross line were distributed in a completely randomized design in a (4×2) factorial arrangement with eight treatments (0, 2, 4, and 6% cottonseed oil with and without ferrous sulfate), and five replicates. The following variables were studied: feed intake, weight gain, feed conversion, weight of organs, blood parameters, and yield of carcass and cuts at 21 days. No effects of the levels of cottonseed oil were found on the performance of animals aged 1 to 7 days, or on the relative weights of the organs. In this same period, the weight gain, and the relative weights of heart, liver, and intestine of the animals that received ferrous sulfate were decreased, and feed conversion was worsened. In the period from 1 to 21 days, weight gain increased linearly with the increase in the levels of cottonseed oil. Blood parameters were not influenced by the diets. Crude cottonseed oil can be utilized in diets for broilers in the periods from 1 to 7 and 1 to 21 days of age at up to 6% of inclusion, and supplementation with ferrous sulfate is unnecessary if the differences in metabolization of the cottonseed oil are considered, with and without, it during the diet formulation process
