Disseminated Transmissible Venereal Tumour Associated With Leishmaniasis in a Dog

This report addresses an atypical transmissible venereal tumour in an 8-year-old bitch that was pluriparous and seropositive for leishmaniasis. There were ascites and a serosanguineous discharge from the vulva, but no lesions on the external genital mucosa. An aspirate of the peritoneal fluid showed mononuclear round cells characteristic of transmissible venereal tumour (TVT). Exploratory laparotomy revealed light red, granulomatous structures in the peritoneum, omentum, spleen, liver and uterine horns. Cytological and histopathological tests confirmed the diagnosis of intra-abdominal TVT. Dissemination of the TVT to several organs inside the abdominal cavity probably resulted from immunosuppression caused by leishmaniasis, which favoured the presence and aggressiveness of TVT.

Angioarquitetura venosa do órgão genital da fêmea bovina

Investigou-se a angioarquitetura venosa da genitália de fêmeas bovinas não prenhes, para avaliar a presença de possíveis anastomoses dos vasos provenientes da região da vulva e da vagina com a veia útero-ovariana, usando-se cinco peças obtidas em abatedouros. No laboratório, um ramo da veia vaginal caudal, infundido com contraste radiográfico intravascular, foi submetido à radiografia. Observou-se que a veia vaginal forma intensa rede de anastomoses na superfície ventral do útero, entre os antímeros direito e esquerdo. As genitálias apresentaram anastomoses dos vasos vulvares e vaginais com vasos da cérvice, corpo e cornos uterinos, sugerindo que parte de um agente luteolítico administrado via intravulvosubmucosa pode ser transportado diretamente aos ovários por uma rota local, sem atingir a circulação sistêmica.

Avaliação do comportamento sexual em touros Nelore: comparação entre os testes da libido em curral e do comportamento sexual a campo

Objetivou-se determinar a eficiência do teste da libido realizado em curral em comparação ao teste realizado a campo e relacioná-los à taxa de gestação em estação de monta de 120 dias. Treze touros aptos à reprodução foram submetidos ao teste da libido em curral por 3 horas. Desses touros, nove foram submetidos à avaliação a campo na proporção touro:vaca de 1:33. A cada 21 dias, foi diagnosticada a gestação por meio de avaliações ultra-sonográficas. No teste em curral, observou-se que, quanto maior o tempo, maiores foram os escores de classificação e que nenhum touro efetuou serviço completo nos 10 minutos iniciais do teste. Com um touro classificado como muito bom obteve-se 84,80% de prenhez, porém touros questionáveis proporcionaram taxas de prenhez de 86,67 e 96,55% ao final da estação. As correlações entre características físicas e morfológicas do sêmen mantiveram-se próximas de zero ou foram nulas. Os principais sinais fisiológicos do comportamento sexual foram o ato de cheirar ou lamber o corpo da fêmea, cheirar ou lamber a vulva, seguidos ou não por reflexo de Flehmen. em animais da raça Nelore, o tempo de 30 minutos de observação mostrou-se mais eficiente para a realização do teste da libido em curral. O teste da libido realizado a campo no período diurno não foi eficaz em predizer a libido de todos os animais estudados, em decorrência, provavelmente, do comportamento sexual noturno de alguns reprodutores.

Quadro citológico vaginal, concentração plasmática de progesterona durante a gestação e medidas fetais em paca (Cuniculus paca Linnaeus, 1766)

Em 27 pacas (Cuniculus paca Linnaeus, 1766) objetivou-se descrever aos 30, 60 e 90 dias (D) de prenhez diagnosticada por ultrassonografia (US), os tipos celulares do epitélio vaginal em esfregaços vaginais, relatar as condições de abertura da vulva e as características do muco vaginal, determinar a concentração plasmática de progesterona (P4) por radioimunoensaio, e ainda, mensurar por ultrassonografia (US) o diâmetro biparietal (DBP) fetal aos 60 e 90 dias de prenhez. No D30, 40% das amostras exibiram células (com características estrogênicas) superficiais e presença de núcleos nus. Nos D60 e D90, células parabasais, intermediárias, superficiais e naviculares estavam presentes nas mesmas proporções, mas células endocervicais foram descritas em apenas 73,9% e 69% das amostras daqueles dias, respectivamente. No D30 a maior proporção de células naviculares e superficiais diferiu (p < 0,05) em relação aos outros tipos celulares presentes. O muco vaginal apresentou-se cristalino e fluido em 100% e em 70% das fêmeas nos D30 e D60, respectivamente. Observou-se o vestíbulo vaginal aberto em torno de 50% das fêmeas em todos os dias de exames. Valores mínimos detectáveis de P4 foram obtidos em 72% e em 83% das fêmeas, enquanto que as médias das medidas dos DBP foram 1,25 cm (± 0,16) e 2,34 cm (± 0,25) nos D60 e D90, respectivamente. O quadro citológico vaginal nos D30, D60 e D90 e o DBP fornecem elementos que contribuem para diagnóstico de gestação em pacas. A concentração de P4 demonstra a necessidade de maiores estudos da endocrinologia da gestação em pacas.

Pratylenchus jaehni sp n. from citrus in Brazil and its relationship with P-coffeae and P-loosi (Nematoda : Pratylenchidae)

A lesion nematode population infecting citrus in the state of São Paulo, Brazil is described and named Pratylenchus jaehni sp. n. Biological, molecular and morphological characteristics of this new species are compared with those of the morphologically similar P. coffeae and P. loosi. Results of mating experiments showed that R jaehni is reproductively isolated from P coffeae. Molecular (D2/D3 DNA sequences) dissimilarities among P. jaehni sp, n., P. coffeae and P. loosi were documented in a previous study. The morphology of seven R coffeae populations from tropical America and eastern Java and a P loosi population from Sri Lanka is used for comparison with the morphology of P. jaehni sp. n. Pratylenchus jaehni differs from R coffeae and P. loosi by only a few morphological ;characters of the females. The mean values of stylet length, stylet knob height, and vulva position are smaller (less than or equal to15 vs greater than or equal to15 mum, less than or equal to2.7 vs greater than or equal to2.7 mum, less than or equal to79 vs greater than or equal to79%) than those in P coffeae and P loosi. The tail terminus is usually subhemispherical and smooth in P jaehni sp. n.. whereas it is commonly truncate and indented in most P. coffeae populations and bluntly or finely pointed in P. loosi. Because of the morphological similarities among P. jaehni sp. n., P. coffeae and P. loosi, examination of at least ten specimens is required to obtain a reliable diagnosis based on morphology. Nineteen morphometric parameters for P. jaehni sp. n. and P. coffeae ranged from 0-13% smaller in fixed than in live specimens.

Epidemiology of sheep myiases in São Paulo State, Brazil

A survey of Diptera species causing cutaneous myiases on sheep in Botucatu, São Paulo, Brazil was made to determine seasonal incidence, predilection sites and the factors predisposing to infestation. Sheep were checked daily for myiases for one year. At two week intervals larvae from wounds were collected for identification. Only larvae of Dermatobia hominis and Cochliomyia hominivorax were found. Myiases due to C. hominivorax were observed during the whole year with high incidence from January to April. The feet, vulva, tail and scrotum were most frequently infested. Wounds were the commonest predisposing factor. © 1992 Centre for Tropical Veterinary Medicine, University of Edinburgh.

Rectovaginal fistula with anal atresia in 5 dogs

Five dogs with rectovaginal fistula and atresia ani that had been treated by surgical correction of the malformations were studied retrospectively. Ages at presentation varied from 1 to 3 months and weight from 350 g to 7.5 kg. The histories included voiding of feces through the vulva, with or without tenesmus, usually observed after weaning. Artesia ani, presence of feces in the vaginal canal, abdominal distention, and discomfort on abdominal palpation were observed during clinical examination. Also, 3 dogs had partial tail agenesis. In all dogs, the rectovaginal fistula was isolated and transected, the vulvar and rectal defects were closed separately, and the atresia ani was repaired. Normal defecation was restored, but 1 dog had fecal incontinence that subsequently resolved. One dog died 2.5 months postoperatively, and follow-up was done on the others for periods ranging from 1.6 year to 7.7 years. Surgical correction in dogs with rectovaginal fistula and atresia ani may result in a favorable outcome, if it is done early.

Anovulvar cleft and vaginal prolapse-hyperplasia in a bitch

This report presents the case of a nine-month-old bitch with incomplete occlusion of the skin and mucosa between the anus and dorsal commissure of the vulva. This anomaly, known as anovulvar cleft, was associated with a vaginal prolapse-hyperplasia. Anovulvar cleft is a rare condition in bitches and is caused by incomplete closure of the dorsal urogenital folds. Anovulvar cleft can lead to clitoritis, abrasion, dryness and devitalisation of the smooth exposed mucosa. Surgery can correct the condition. In the present study, surgical resection of the hyperplasic vaginal tissue associated with perineoplasty using an inverted V-shaped incision showed excellent results. An ovariohysterectomy was also performed to prevent recurrence of the vaginal prolapse-hyperplasia. © 2007 British Small Animal Veterinary Association.

Equine Perineal and Vulvar Conformation Correction Using a Modification of Pouret's Technique

An incompetent vulvar seal leads to reproductive failure, and a surgical intervention might be required. The present paper describes modifications to Pouret's surgery. We suggest the use of a simple interrupted vertical mattress suture, which avoids seroma. Eighteen Brazilian Jumping Horse mares, older than 20 years and barren for 3-5 consecutive years, underwent modified Pouret's surgery. A horizontal skin incision of 3-4 cm was made half way between the anus and upper commissure of the vulva. The submucosal and connective tissue were dissected, and the rectovaginal shelf was split horizontally by sectioning the muscular and ligamentous connections between the anus, vulva, caudal portion of the rectum, and vagina until the vulva was oriented vertically. The wound was changed from a horizontal plane to a vertical plane by placing the suture vertically using approximately eight interrupted U sutures distributed in two layers with polyamide thread. The modified Pouret's surgical technique provided a perfect coaptation of the vulvar lips and a correct perineal position. Those mares that presented with horizontally tipped vulvar lips due to advanced age and stretching of the pelvic tissues by multiple foaling had their vulvas replaced. Also, the surgical procedure was easy to perform. As to fertility, of the 18 initial mares, 14 were inseminated, and all became pregnant. Thus, it was possible to conclude that the anatomical changes performed throughout the surgical procedure predisposed to a better vulvar coaptation, correcting the pneumovagina. © 2013 Elsevier Inc.
