BRasil: Polymelia and duplication of the descending colon in a Poodle dog -a case report. Vet. arhiv 88, 149-157, 2018. aBsTRaCT this study describes a six-month old female Poodle dog born with a third hind limb and duplication of the descending colon. the extra limb was projected dorsally toward the coccygeal vertebrae and was slightly displaced to the left of the median body axis next to the anus. Although the animal walked without difficulties, it showed signs of discomfort when defecating and sitting. a plain radiograph demonstrated that the extra limb articulated from the left ischium and a contrast radiograph showed that the descending colon was not only duplicated but it adjoined the segments in the rectum, ending with one anal opening. Surgery was performed to amputate the extra limb. the disarticulation of the extra limb from the left ischium was easy to perform and minimally invasive. Intestinal intervention was not performed since it was determined that the animal could live a healthy life with the duplicated colon. Fifteen days after surgery the animal showed no signs of discomfort and was able to sit and defecate normally.
Mast cell tumors represent the most common malignant skin tumor in the dog. This review outlines the incidence, etiology and clinical signs of mast cell tumors. Diagnostic tests, staging and treatments are also discussed.
Schwannoma refere-se à neoplasia que se origina das células de Schwann, localizadas no sistema nervoso periférico e são incomuns em cães. Um cão, macho, da raça Boxer, com dez anos de idade, foi encaminhado com queixa principal de um nódulo cutâneo em localização torácica lateral direita, próximo às primeiras costelas. Durante o exame clínico observou-se que o nódulo media aproximadamente 5 cm de diâmetro, possuindo formato arredondado, consistência firme e não ulcerado. Foram realizados exames pré-operatórios de rotina e optou-se pela retirada cirúrgica da massa. Na microscopia de luz observou-se uma massa de característica neoplásica apresentando formato ovalado bem delimitada e com crescimento expansivo. As células estavam distribuídas em ninhos com feixes celulares. Os núcleos eram fusiformes e de tamanhos variados. Não foram observadas figuras de mitoses. O diagnóstico foi baseado nas descrições morfológicas das células neoplásicas. Conclui-se que o Schwannoma foi uma neoplasia de características histológicas e comportamento benigno devido à localização distal a nervos da raiz da medula.
Frente ao avanço na utilização das biotécnicas reprodutivas e aos poucos dados referentes ao desenvolvimento gestacional em suínos, faz-se necessária a aplicação de método eficiente de diagnóstico de gestação e da estimativa de idade fetal. Assim, foram submetidas a exames ultrassonográficos, em modo-B, sete fêmeas suínas gestantes, da raça Landrace, em diferentes estádios gestacionais com objetivo de diagnosticar a gestação e estudar parâmetros sobre o desenvolvimento embrionário e/ou fetal dos leitões. Concluiu-se que a ultrassonografia mostrou ser um método bastante acurado e apropriado no diagnóstico gestacional e na avaliação da biometria e morfologia fetais, sendo que o diâmetro biparietal teve o maior número de mensurações quando comparado às demais variáveis, sendo as mesmas consideradas acuradas em virtude das datas de cobertura e de parto serem conhecidas. No entanto, novos estudos devem ser realizados na espécie suína, comparando-se a técnica de biometria fetal em diferentes raças e em diferentes estádios gestacionais.
RESUMO:O presente estudo teve como objetivo acompanhar a dinâmica folicular de dez éguas submetidas à inserção do dispositivo de liberação lenta de progesterona e, verificar se este procedimento antecipa o início da ciclicidade ovariana em éguas em anestro. Para isso, foram colhidos dados do uso de implante intravaginal de progesterona em éguas que se encontravam em anestro. Após dez dias da colocação do implante, o mesmo foi removido e administrado 0,25 mg de prostaglandina F2α por via intramuscular. As éguas foram diariamente acompanhadas, por meio de exame ultrassonográfico, até o folículo ovariano apresentar-se com 35 mm de diâmetro para se administrar hCG e GnRH e, no dia seguinte, realizar-se a inseminação artificial e aguardar a ovulação. Oito dias após a ovulação foi realizada a coleta dos embriões. Dentro das condições do presente experimento, concluímos que a utilização do implante intravaginal de progesterona sobre a ciclicidade das éguas em anestro demonstrou 80% de eficácia, conseguindo-se 75% de embriões viáveis. Podemos concluir, também, que a faixa etária das éguas não influenciou a eficácia do implante, já que éguas com idade entre três e 25 anos foram responsivas ao uso do implante intravaginal de progesterona.Palavras-chave: Éguas.

EFFECT OF INTRAVAGINAL PROGESTERONE IMPLANT CYCLICALITY ON OF MARES IN ANESTROUS QUARTER MILE RACE SUMMARY:The purpose of the present paper was following up the follicular dynamic of ten mares submitted to the insertion of the device for slow liberation of progesterone and, knowing whether or not it accelerated the beginning of the ovarian cyclicity in mares in anestrus. For that reason, were collected data about the use of progesterone intravaginal implantation were in anestrus. 10 days after the implantation placement, the same was removed and it was administered prostaglandin F2α. The mares were followed up through US till the follicles were 35 mm of diameter to administer human chorionic gonadotropin (hCG), in order to, on the following day, accomplishing the IA and waiting for ovulation. Then, after eight days it was accomplished the embryos collection. Within the conditions of the present experiment, we've concluded that using the progesterone intravaginal implantation on the cyclicity of mares in anestrus has demonstrated 80% of efficacy, making it possible obtaining 75% of viable embryos. We can conclude also that, the mares age group hasn't influenced the implantation efficacy, since the mares between 3 and 25 years old were responsive to the use of progesterone anestrus.
PURPOSE: To induce a total extra-hepatic obstructive jaundice in swines, by ligation of the common bile duct by laparoscopic surgery. METHODS: Eight swines of the Landrace race, 36-day-old, originated from the same matrix, distributed in two groups. Group A: was used titanium metal clip to the common bile duct ligation in three animals; group B: were ligated with 2-0 cotton thread in five animals. RESULTS: The ligation of the biliary ducts was performed successfully in all animals, with easy identification of the common bile duct by laparoscopy. There weren't difficulties in the procedures, mainly due to the increased surgical field provided by the excellent quality of light and image of the appliance. The clinical signs of jaundice were evident in the animals in seven days. In group A, two animals showed bile duct perforation near the clip, probably due to ischemic necrosis, progressing to peritonitis and death. In group B, five animals showed obstructive jaundice without any amendment. CONCLUSION: Under the conditions of this study, we therefore recommend the use of unabsorbed wires to experimental biliary obstruction, in order to avoid complications, such as ischemia and necrosis, followed by perforation of the wall of the bile ducts.
This study focuses on a case of a red-howler monkey (Alouatta guariba clamitans) which was found with a fetus in a transverse lie position with a prolapsed arm. The topic of this research is well justified as there are no data on this condition involving this type of non-human primate in literature. In this study, a red-howler monkey was observed by locals pulling at her pelvic region for 3 days near a farm. On the third day, the monkey was found lying on the ground at which point she offered no resistance when approached. The environmental police took the monkey to receive medical attention. During the physical examination, it was quickly observed that the monkey was pregnant; the right forelimb of the fetus was exposed from the vulva. An ultrasound revealed a non-viable fetus, and due to the severe weakness of the mother, we opted for euthanasia. During the necropsy, not only was the fetus found macerated but it was also in a transverse lie position with a prolapsed arm and presented no external or internal injuries consistent with trauma.
