Objective: To present a model for research and training in multivisceral transplantation in pigs. Methods: Eight Large White pigs (four donors and four recipients) were operated. The multivisceral transplant with stomach, duodenum, pancreas, liver and intestine was performed similarly to transplantation in humans with a few differences, described below. Anastomoses were performed as follows: end-to-end from the supra-hepatic vena cava of the graft to the recipient juxta diaphragmatic vena cava; end-to-end from the infra-hepatic vena cava of the graft to the inferior (suprarenal) vena cava of the recipient; and endto-side patch of the aorta of the graft to the infrarenal aorta of the recipient plus digestive reconstruction. Results: The performance of the multivisceral transplantion was possible in all four animals. Reperfusions of the multivisceral graft led to a severe ischemia-reperfusion syndrome, despite flushing of the graft. The animals presented with hypotension and the need for high doses of vasoactive drugs, and all of them were sacrificed after discontinuing these drugs. Conclusion: Some alternatives to minimize the ischemia-reperfusion syndrome, such as the use of another vasoactive drug, use of a third pig merely for blood transfusion, presence of an anesthesia team in the operating room, and reduction of the graft, will be the next steps to enable experimental studies.

Acute renal failure (ARF) may be defined as a subtle loss of renal function, leading to accumulation of nitrogenated substances. Several causes may lead to the development of ARF in an animal, including severe shock, intense blood loss, hypotension, dehydration, hypovolemia, deep anesthesia and nephrotoxins. Fluid therapy remains the basis of ARF treatment in animals. Thee therapeutic objective is to normalize fluid balance, solve hemodynamic problems and promote urine production. The objective of the present study is to review the procedures to manage acute renal failure in dogs and cats.

The present study describes a technique to obtain consecutive luteal samples by colpotomy. The animals received an epidural anesthesia and local anesthesia (vaginal vault) and after ten minutes the vaginal vault was incised with a scalpel blade and tissue was dissected to provide access to the pelvic cavity and to retract the ovary into the vagina. Then, a luteal biopsy was performed with a Yomann biopsy nipper. Signs indicative of pain and stress during the vaginal vault incision, traction of ovary or luteal biopsy were observed only in two collections. However, these signs were observed in ten collections during dissection of the vaginal wall and peritoneum. The occurrence of ataxia was observed in 26 collections and it was usually related to a longer duration of the procedure. Ataxia could be divided in light (15/26), moderate (6/26) and severe (5/26). The occurrence of ovarian adhesions ipsilateral to the incision was evaluated only in the initial four collections. Adhesions were present in 16 collections. The protocol described above provided a safe and efficient method to acquire luteal samples. The low incidence of adhesions allows the consecutive use of females without any interference in subsequent ovulations and collections.

Contexto e objetivo: A hanseníase caracteriza-se por ter diagnóstico eminentemente clínico, principalmente através da constatação de hipo ou anestesia das lesões, ou seja, sem necessariamente o uso de exames adicionais, como baciloscopia e biópsia, utilizados para classificação clínica da doença. Buscou-se definir se há tendência à desvalorização da avaliação clínica em favor do excesso de exames complementares, investigar a adequação do registro nos atendimentos da atenção básica e compará-los com o obtido em serviço de média complexidade. Desenho e local: Estudo transversal, de base populacional, utilizando registros de prontuários, realizado em dois âmbitos de atendimentos de saúde da cidade de Campinas (SP): os Centros de Saúde e a assistência dermatológica especializada de hospital de ensino. Métodos: Os registros foram investigados por meio da aplicação de checklist, contendo itens indispensáveis ao atendimento a hansenianos. Associações foram testadas pela prova de Goodman e ao nível de 5% de significância. Resultados: Foram avaliados 33 prontuários oriundos dos centros de saúde e 36 do hospital, observou-se polarização entre registros adequados e ausentes, evidenciando a presença de efeito tudo ou nada nos atendimentos; de 26 variáveis, apenas em 5 (19,23%) obteve-se predomínio da avaliação do hospital sobre os centros de saúde; evidenciou-se dependência de exames complementares, solicitados em 67 dos 69 atendimentos (97,10%), para diagnóstico da doença. Conclusão: Confirmou-se, neste estudo, déficit da avaliação médica e indicação inadequada de exames adicionais. Por associar-se com excesso de solicitação de exames, a observação clínica mostrou-se incompleta, comprometendo a capacidade diagnóstica dos atendimentos a hansenianos.
