Transplante multivisceral em suínos: modelo de pesquisa e treinamento

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.

Ataque de jacaré a pescador no Pantanal de Mato Grosso (Brasil): relato de caso

Contexto: O manuscrito descreve o ataque não provocado de um jacaré-do-Pantanal a um pescador. Ataques por jacarés são pouco relatados e a espécie do Pantanal raramente causa acidentes. Descrição do caso: A vítima foi mordida na mão direita quando limpava peixes nas margens do rio Paraguai, por um jacaré de cerca de 1,5 m que saiu debaixo da vegetação aquática. O paciente apresentou dor, secreção purulenta e febre e procurou auxílio médico, apresentando ferimentos perfurocontusos e perfurocortantes e fratura-arrancamento no segundo metacarpiano direito. Após cinco dias de internação, houve significativa regressão do processo inflamatório, quando obteve alta hospitalar para posterior acompanhamento ambulatorial. Discussão: Os acidentes por jacarés podem ser muito graves, devido à dentição e à potência das mandíbulas desses répteis. Embora algumas espécies amazônicas possam predar seres humanos, o jacaré-do-Pantanal não causa mortes, mas mesmo espécimes de pequeno tamanho podem causar lesões graves e infecção secundária importante, como observado no caso. Conclusões: Devido ao potencial traumático e capacidade de inoculação de micro-organismos, as mordidas de jacarés devem ser encaradas como ferimentos de alto risco pelas equipes de saúde.

Estudo retrospectivo (2007-2011) da casuística de cães com mastocitomas cutâneos atendidos em um hospital-escola

Neoplasms of mast cell origin are uncommon in most animal species. Although cases of cutaneous mastocitoma (CM) are rare in humans, it is the second most diagnosed cancer in dogs, accounting for approximately 20% of cutaneous tumors in this species. The age group most frequently affected is between eight and nine years, but it may occur in animals up to three weeks old. This study aimed to describe the epidemiological, hematological and histopathological characteristics of 73 dogs with cutaneous mast cell tumors attended between 2007 and 2011 by the Oncology Service of a teaching hospital in the state of São Paulo. Data collected included race, age, sex, weight, skin region affected, blood tests results at the first consultation and histopathological grading of dogs diagnosed with this neoplasia.

Avaliação da participação e confiabilidade da população em relação à campanha de vacinação anual contra a raiva de cães e gatos no município de Botucatu, São Paulo, Brasil

The annual vaccination campaign against rabies is the most effective prevention procedure for this disease in dogs and cats and hence for human protection also. However, in 2010 and 2011, this activity was interrupted in Brazil due to the occurrence of adverse events associated with vaccination. Even though cases of canine rabies have been decreasing in the last two decades, vigilance must be strengthened in order to maintain pet owners trust in the vaccines provided in public services. This study aimed to determine pet owners participation in the annual vaccination campaign carried out in Botucatu. During March and April 2012, the period before the 42nd campaign, 312 pet owners, dogs and cats, were interviewed. The homes were randomly drawn in blocks from different sectors of the city; all houses on the same block over the 120 km² of urban area participated in the sampling process. Statistical analysis was performed descriptively. The results showed that the owners main motivation to vaccinate their pets during the campaigns is rabies prevention (36%), followed by the proximity of the vaccination station to the house (20.7%), zero cost (10.9%), and the combination of all three factors (16.1%). When asked if they would take their animals back to be vaccinated in another campaign, 60.1% answered yes, 13.5% would go to a private clinic, 2.2% would not take because they do not trust the vaccine and 1.6% had not decided yet. We conclude that the respondents have realized how dangerous Rabies is, because even after the break period, they still utilized the vaccination campaign demonstrating confidence in its effectiveness, while knowing the campaign goals facilitates understanding and participation.

Prevalence and geographical distribution of Toxoplasma gondii in dogs in the urban area of Botucatu, SP, Brazil

Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii, and can infect a wide variety of animals including humans. Domestic animals can be an important sentinel population for infection in the community. Occurrence of T. gondii infection was assessed in dogs in the urban area of Botucatu city, SP, Brazil. In the sample, 10% rate for error estimate, 95% confidence interval, and 5% significance level were established. Serum samples were collected from dogs during a rabies vaccination campaign, and were processed using modified agglutination test (MAT). Blood samples were collected from 670 dogs, with homogeneous distribution in five regions in the urban area, representing 3.74% of 17,910 animals vaccinated. In this sample, 17.3% (116/670) dogs (68 – 58.6% female and 48 – 41.4% male) were positive for T. gondii infection (p<0.03). Regarding age of the infected dogs 4.6% (4/88) were younger and 95.4% (84/88) were older than one year (p<0.01); the age of 28 positive animals were undetermined. The serum titers of anti-T. gondii antibodies were: 16 (69.8%; 81/116), 64 (13.8%; 16/116), 256 (15.5%; 18/116), and 1024 (0.9%; 1/116). Prevalence was distributed among the North 14.2% (19/134), South 18.0% (31/172), East 15.7% (19/121), West 21.6% (27/125), and Central 16.9% (20/118) regions of the municipality (p=0.5). In all these regions, females and dogs aged more than one year showed a higher occurrence of T. gondii infection (p<0.05).

Alimentos tóxicos para cães e gatos

Pet animals are closer to their owners and for this reason erroneously share the same alimentation. Several substances can cause intoxication or poisoning in dogs and cats, being many of those also found in human food. Some foods that are edible for humans or even to other animal species can be risky for dogs and cats due to different metabolic pathways, and further damage can be caused depending on the amount or concentration consumed. Poisoning in animals occur intentionally or accidentally in the household of its owner, occurring acute onset of clinical signs. Thus, the objective of this review was to present the food products for humans that cannot be given to dogs and cats as well as clinical signs characteristic of a toxicosis, also demonstrating the therapy for the damage created by consumption of those substances. This review explores the mechanisms of action and clinical signs of toxicosis caused by chocolate, xylitol, macadamia nuts, onions, garlic, grapes and raisins, avocado, alcoholic beverages and milk.
