RESUMOObjetivando analisar a prevalência de TVT em relação ao sexo, raça, idade, localização da lesão e resposta ao tratamento quimioterapêutico foi realizado um estudo retrospectivo de 144 cães atendidos no Hospital Veterinário da Universidade de Uberaba (HVU) durante os anos de 2007 à 2012, diagnosticados com TVT através da realização de exames de cito ou histopatologia. Destes, 59% eram cães sem raça definida (SRD). Apesar de 16,7% dos cães avaliados não terem suas idades determinadas, os resultados desta pesquisa revelaram que os pacientes apresentaram idade variando entre 1 e 15 anos sendo a faixa etária entre 2 e 8 anos (40,2%) a mais afetada. Em relação ao sexo, este trabalho demonstrou que as fêmeas foram mais acometidas que os machos (66,7 e 33,3% respetivamente). Observou-se que a principal localização da neoplasia foi a vulva (65,3%), seguida pelo pênis (30,6%), cavidades nasal (3,5%) e oral (0,7%). Dentre os 54 cães que foram submetidos ao tratamento no hospital veterinário, 39 concluíram o protocolo, sendo que 33 apresentaram citorredução completa utilizando vincristina como agente único; 3 animais se encontravam em tratamento ao final do estudo e nos 3 casos em que houve quimiorresistência, os pacientes se beneficiaram de doxorrubicina. PALAVRAS-CHAVE: cão, doxorrubicina, vincistina. SUMMARYTo analyze the prevalence of TVT in relation to sex, breed, age, lesion location, and response to chemotherapeutic treatment, a retrospective study from 2007 to 2012 was conducted with dogs from the Veterinary Hospital of the University of Uberaba (HVU) diagnosed with TVT by cytology or histopathology. Which, 59% were mongrel dogs (59%). Although 16.7% of these dogs had their ages undetermined, the data of this study showed that patients were aged between 1 and 15 years being the range between 2 and 8 years (40.2%) the most affected. Regarding sexual predisposition, this study shows that females were more affected than males (66.7, 33.3% respectively). The primary site of the tumor occurrence was the vulva (65.3%), followed by the penis (30.6%), nasal (3.5%) and oral cavities (0.7%). Among 54 dogs that were treated at the hospital 39 dogs completed therapeutic protocol, of these 33 dogs had complete cytoreduction using the single-agent vincristine, 3 animals were still receiving treatment at the end of the study and in the 3 chemoresistance cases, these patients were benefited from doxorubicin treatment.

Pleuroperitoneal hernias are the most uncommon type of diaphragmatic hernias in dogs and cats. The treatment of choice is surgery and may involve the use of prosthetic implant through celiotomy. In the current report, laparoscopic repair of a congenital pleuroperitoneal hernia using polypropylene mesh in a dog is described. The surgery was feasible. Appropriate reduction of the hernia was carried out and no complications were noted.

RESUMO A ovariohisterectomia (OH) eletiva em cadelas é o procedimento mais realizado na cirurgia de pequenos animais. No presente trabalho, foram utilizados três grupos de sete animais (GI, GII e GIII), submetidos a três técnicas de ABSTRACT The elective ovariohysterectomy (OH) is the most frequent procedures performed in dogs. In this study was used three groups of seven animals each (GI, GII, and GIII) that was undergone to three elective OH techniques: (i) mini-celiotomy ("Snook-hook technique"), (ii) hybrid Natural Orifi ce Translumenal Endoscopic Surgery (NOTES), and (iii) celiotomy ("conventional surgery"

ResumoA uretrostomia é técnica cirúrgica utilizada em casos de obstrução parcial ou total da uretra, e na abordagem laparoscópica pode ser uma opção de tratamento. Devido à escassez de estudos envolvendo essa técnica, este trabalho relata o caso de uretrostomia pré-púbica videoassistida (laparoscópica híbrida) em um felino com estenose uretral. O paciente de cinco anos de idade apresentando histórico de doença do trato urinário inferior dos felinos (DTUIF) recorrente, havia sido submetido a uretrostomia perineal há dois anos e nove meses. Depois desse procedimento, o paciente passou por mais quatro cirurgias corretivas sem sucesso. Após realização de exames laboratoriais (hemograma e bioquímicos) e de imagem, o animal foi submetido a uretrostomia pré-púbica laparoscópica híbrida, obtendo-se sucesso terapêutico e possibilitando ao paciente adequada qualidade de vida. Conclui-se que esta técnica é viável e segura em gatos, tornando-a uma possível escolha de tratamento cirúrgico para estenose uretral. Palavras-chave: Estenose da uretra, videocirurgia, gatos, cirurgia urológica AbstractUrethrostomy is a surgical technique used in cases of partial or total obstruction of the urethra, and the laparoscopic approach may be a treatment option. Due to the scarcity of studies involving the technique, this paper reports the case of laparoscopic-assisted pre-pubic urethrostomy (hybrid laparoscopic) in a cat with urethral stricture. A five-years-old cat presenting recurrent feline lower urinary tract disease (FLUTD) had undergone to perineal urethrostomy two years and nine months ago. After this procedure, the patient underwent another four corrective surgeries without success. Laboratory tests (blood count and biochemical) and image diagnosis were realized. The patient was subjected to laparoscopic-assisted pre-pubic urethrostomy and it was achieved therapeutic success and adequate patient quality of life. It is concluded that this technique is feasible and safe in cats, making it a possible choice of surgical treatment for urethral stricture.

Objectives The aim of this study was to evaluate the effectiveness of ovariohysterectomy (OVH) on feline mammary fibroepithelial hyperplasia (FMFH) treatment, as well as the influence of previous injectable progestin on clinical signs and treatment of FMFH. Methods Seventy-nine female cats diagnosed with FMFH between 2014 and 2018 were included. The animals were distributed as follows: (1) treated only with OVH (TA) or OVH plus antiprogestin (TB); and (2) no administration (G1) or previous administration (G2) of injectable progestin before FMFH diagnosis. Data regarding clinical signs of FMFH, occurrence of persistent mammary growth after OVH, and time until complete remission of FMFH post-surgery were recorded and evaluated. Results Mastectomy was not performed in any cat during the study. TA was adopted in 71/79 (89.9%) cases, with 42/71 (59.2%) from G2 and 29/71 (40.8%) from G1. TB was adopted in 8/79 (10.1%) cats, all from G2. Total remission of FMFH was observed in 73/79 (92.4%) cats, with six animals from G2 having died (n = 6/79 [7.6%]). The time until complete remission of FMFH was higher ( P <0.0001) in cats from G2 than from G1. Moreover, animals from G2 had a higher percentage of persistent mammary growth after OVH ( P <0.001) and a tendency to higher mortality ( P = 0.052) compared with G1. Conclusions and relevance Previous treatment with injectable progestin may result in a more complex clinical presentation of FMFH. Ovariohysterectomy is a good treatment option for FMFH when there is no interest in breeding the queen. Treatment with antiprogestin is recommended, especially if persistent mammary growth is detected after OVH.

De 2006 a 2013 foram diagnosticados 81 casos de doença vestibular canina no serviço de rotina em neurologia de um hospital veterinário universitário do sul do Brasil. Desses, aproximadamente dois terços foram diagnosticados com doença vestibular central (DVC) e cerca de um terço como doença vestibular periférica (DVP). Cães com raça definida foram mais acometidos que aqueles sem raça definida, principalmente Dachshund (DVP) e Boxer (DVC). Os principais sinais clínicos observados, tanto na DVP quanto na DVC, incluíram: inclinação de cabeça, ataxia vestibular e estrabismo ventral ou ventrolateral. Deficiência proprioceptiva, disfunção dos nervos cranianos V-XII e alteração de nível de consciência foram vistos apenas em casos de DVC, já a ausência de reflexo palpebral ocorreu apenas em casos de DVP. Doenças inflamatórias/infecciosas, principalmente cinomose e otite bacteriana, foram as condições mais comumente associadas à DVC e à DVP, respectivamente. Esse artigo estabelece os aspectos epidemiológicos (sexo, idade e raça) e a prevalência dos sinais clínicos observados em cães com doença vestibular na Região Central do Rio Grande do Sul, discute a utilização dos achados clínicos no diagnóstico correto e na diferenciação entre DVC e DVP, e define quais as principais doenças responsáveis pela ocorrência dessas duas síndromes clínicas.
