ABSTRACT Purpose To evaluate hemostasis of the ovarian arteriovenous complex (OAVC) in relation to surgical time, practicality and feasibility in three ovariohysterectomy (OH) techniques for queens. Methods The experiment was performed on 21 female cats aged between six months and seven years, randomly arranged into three groups in a completely randomized design. Group one was spayed using the conventional three-clamp technique, group two using the OAVC knotting technique, and group three using the ovarian pedicle rotation technique. The student’s t-test and Tukey’s test were used to compare the mean surgical times. Results The conventional technique, which uses thread wires, was more laborious and required longer execution time compared to the other two techniques. The OAVC knotting technique was the fastest and had the least blood loss. Conclusions The use of techniques that do not use synthetic materials for OAVC hemostasis was proven to be appropriate in castration projects, provided that the surgical team has sufficient training.

RESUMO: O objetivo do presente artigo foi realizar uma pesquisa bibliométrica sobre publicações científicas brasileiras que descrevem cirurgias ortopédicas experimentais em cães. Foram analisadas 14 publicações, havendo grande variação no número de animais experimentais, demonstrando que não há consenso sobre o número adequado para um experimento científico ortopédico com cães. A maioria tinha sido analisada por um comitê de ética (13/14; 92,85%) e apenas dois artigos (2/14; 14,28%) não informaram o uso de protocolo analgésico. Entre os analgésicos, a morfina foi a mais utilizada, tendo sido observada em sete estudos (7/14; 42,85%). Em seis publicações (6/14; 42,85%) o destino final dos animais não foi informado, mas em quatro experimentos (4/14; 28,57%) os cães foram eutanasiados. Também em quatro estudos (4/14; 28,57%) os animais foram encaminhados para adoção. Em conclusão, a ética em pesquisa animal no Brasil avançou, mas há necessidade de planejamento adequado no número amostral.

ABSTRACT: The aim of this paper was to conduct a bibliometry search about Brazilian scientific publications that describe experimental orthopedic surgeries in dogs. It was analyzed 14 publications, and there was wide variation in the number of experimental animals, showing that there is no consensus on the appropriate number for science experiment with dogs. Most articles had been reviewed by an ethics committee (13/14, 92.85%) and only two articles (2/14; 14.28%) did not report the use of analgesic protocol. Among analgesics, morphine was the most widely used, noted in seven studies (7/14; 42.85%). In six of the articles (6/14; 42.85%), the final destination of animals was not informed, but in four experiments (4/14; 28.57%) the dogs were euthanized. In four studies (4/14; 28.57%) the animals were sent for adoption. In conclusion, the ethics in animal research in Brazil has advanced, but is necessary proper planning in sample size.

RESUMO: O presente trabalho teve por objetivo caracterizar as oftalmopatias em cães naturalmente afetados por leishmaniose visceral em Teresina, Piauí. O diagnóstico de leishmaniose foi realizado por exame parasitológico de medula óssea e linfonodos. As principais alterações oftálmicas foram uveíte, conjuntivite, blefarite, ceratite e ceratoconjuntivite seca. Anemia normocítica normocrômica foi a principal alteração hematológica, seguida de trombocitopenia. Em relação às proteínas plasmáticas observou-se hiperproteinemia, hiperglobulinemia e hipoalbuminemia. A histopatologia ocular revelou processo inflamatório moderado constituído por linfócitos, monócitos, neutrófilos e macrófagos. Os resultados da pesquisa apontam para a necessidade de se realizar diagnóstico diferencial para Leishmania sp. em cães que apresentem lesões oftálmicas em regiões endêmicas.

ABSTRACT: This study aimed to characterize ocular diseases in dogs naturally affected by visceral leishmaniasis in Teresina, Piauí State, Brazil. The diagnosis was made using parasitological exams of the bone-marrow and lymph-node samples. The main ophthalmological findings were uveitis, conjunctivitis, blepharitis, keratitis, and keratoconjunctivitis sicca. Normocytic normochromic anemia was the main hematological finding, followed by thrombocytopenia. Plasma proteins were also considered, and hyperproteinemia, hypergammaglobulinemia, and hypoalbuminemia were observed. Ocular histopathological examination revealed mild inflammation involving lymphocytes, monocytes, and macrophages. Results indicate the need to perform a differential diagnosis to rule out or establish the presence of Leishmania sp. in dogs presenting with ophthalmic lesions in endemic regions.

As ulcerações no sistema digestivo de cães são consideradas raras. São descritos dois casos de úlcera gastroduodenal em cães. O primeiro animal apresentou úlcera no duodeno próxima!. O segundo mostrou úlcera perfurada na região pilórica do estômago. Nenhum dos animais apresentou evidências de sangramento, mas as lesões eram profundas e arredondadas. Não houve evidência de patologias concorrentes.

Ulcerations in the dog's digestive system are considered rare. In this paper are described two cases of the gastroduodenal ulcer in dogs. The first animal showed ulcer in the proximal duodenum. In the second animal the ulcer was perfured and localized in the pyloric region of the stomach. The lesions were round and deep, but did not reveal evidence of bleeding. In these cases there were no other diseases.

É feita uma revisão de lesões cirúrgicas do esôfago em pequenos animais, incluindo anatomia e fisiologia, sintomas e diagnósticos de doenças esofágicas, patologias obstrutivas, patologias por extravasamento e anormalidades neuro-musculares.

A review was performed on surgical esophageal diseases in small animals, including anatomy and phisiology, signs and diagnostic of the esophageal diseases, obstructives diseases, disorders by extravasation, and neuro-muscular abnormalities.
