Penectomy and scrotal urethrostomy in dogs: report of four cases / Penectomia com uretrostomia escrotal em cães: relato de quatro casos

Wide trauma and neoplasms constitute the main indications for penectomy and scrotal urethrostomy in the dog. Reconstruction of the prepuce is technically challenging, which may not be feasible in cases of extensive tissue loss, requiring penile amputation. The aim of the current study was to report four cases of penectomy associated to scrotal urethrostomy in dogs. The patients were subjected to hematological, histopathologic exams, thoracic radiographs and abdominal echographic evaluations for surgical triage. Malignant neoplasms were diagnosed in three patients and fibrosis with extensive penile exposition was found in one dog. The patients were submitted to penile amputation and scrotal urethrostomy postoperative complications included mild hemorrhage in one dog and wound infection and myiasis in another dog. In conclusion, surgical resection followed by penectomy with scrotal urethrostomy was the best option for the treatment of the preputial lesions and resolution was achieved.(AU)

Os traumatismos extensos de prepúcio e pênis, além de neoplasias, constituem as principais indicações cirúrgicas de penectomia associado à uretrostomia escrotal no cão. A reconstrução do prepúcio é desafiadora e torna-se inviável em casos de lesões amplas, requerendo a amputação peniana. O objetivo do presente estudo foi relatar quatro casos de indicação para penectomia associada à uretrostomia escrotal em cães. Os pacientes foram submetidos a exames complementares hematológicos, citologia das lesões, radiografia de tórax, ultrassonografia abdominal foram realizadas para triagem cirúrgica. Em três pacientes diagnosticou-se neoplasias malignas e em um paciente, fibrose com extensa exposição peniana. Os cães foram submetidos a penectomia, associado a uretrostomia escrotal. As complicações pós-operatórias incluíram hemorragia leve em um paciente e infecção e miiase em outro cão. Concluiu-se que a ressecção cirúrgica seguida de penectomia com uretrostomia escrotal foi a melhor opção para as lesões prepuciais, obtendo-se sucesso no tratamento realizado.(AU)

Bovine herpesviruses do not play a major role in the differential diagnosis of rabies in cattle in Southern Brazil / Bovine herpesviruses do not play a major role in the differential diagnosis of rabies in cattle in Southern Brazil

Background: Rabies has long been recognized as the major cause of encephalitis in cattle in Latin American countries. It has been estimated that nearly 50.000 cattle heads per year are lost due to encephalitis in that subcontinent, with a significant economic impact on cattle productive chains. In Brazil only, 2.500 to 3.000 cattle heads are estimated to be lost every year due to rabies. However, it is believed that rabies incidence in cattle is much larger, since usually only a few samples from affected animals in disease outbreaks are submitted to diagnostic laboratories. Rabies encephalitis is promptly and accurately diagnosed; however, particularly when rabies is excluded as causa mortis, the agent responsible for neurological disease of infectious origin often remains undetermined. Two bovine herpesviruses (BoHVs), bovine herpesvirus type 1 (BoHV-1) and bovine herpesvirus type 5 (BoHV-5) are major pathogens of cattle which are widely disseminated in Brazil. As usual in herpesvirus biology, these tend to infect a large number of hosts and establish lifelong latent infections which may occasionally be reactivated. Both viruses, particularly BoHV-5, are often recovered from cases of neurological disease in cattle. The participation of BoHVs in the differential diagnosis of rabies must be evaluated. Besides, there might be associations between the occurrence of rabies and BoH

Two bovine herpesviruses (BoHVs), bovine herpesvirus type 1 (BoHV-1) and bovine herpesvirus type 5 (BoHV-5) are major pathogens of cattle which are widely disseminated in Brazil. As usual in herpesvirus' biology, these tend to infect a large number of hosts and establish lifelong latent infections which may occasionally be reactivated. Both viruses, particularly BoHV-5, are often recovered from cases of neurological disease in cattle. The participation of BoHVs in the differential diagnosis of rabies must be evaluated. Besides, there might be associations between the occurrence of rabies and BoHV infections that deserve investigation. The aim of this study was to investigate whether bovine herpesvirus 1 and 5 would play a significant role in cases of neurological disease where rabies was the presumptive clinical diagnosis. In addition, associations between the occurrence of rabies and BoHV infections were searched for. The approach adopted for conducting such investigations was based on the search for viral nucleic acids as well as classical virus isolation on tissues of cattle submitted to rabies diagnosis over a two-year period, including rabies-positive and rabies-negative specimens. Materials, Methods & Results: Brain tissue samples of 101 cattle originally submitted to rabies diagnosis were collected over a two year period (2009-2010) from various municipalities within the state of Rio Grande do Sul, Brazil. Thirty nine of these samples had the diagnosis of rabies confirmed by standard laboratory diagnostic methods. Aliquots of tissues were submitted to DNA extraction and examined in search for genomes of bovine herpesviruses (BoHV) types 1 (BoHV-1) and 5 (BoHV-5) by as well as for infectious virus. Bovine herpesvirus genomes were detected in 78/101 (77.2%) samples, in which BoHV-1 genomes were detected in 26/78 (25.7%), BoHV-5 genomes in 22/78 (21.8%) and mixed BoHV infections (BoHV-1 and BoHV-5 genomes) were detected in 30/101 (29.7%) samples. In the 39 samples with confirmed rabies diagnosis, BoHV-1 DNA was detected in 9/39 (23%), BoHV-5 DNA in 6/39 (15.4%) and mixed infections with both BoHV types in 16/39 (41%) samples. However, no infectious herpesvirus was recovered from any of the specimens examined. Discussion: The high prevalence of BoHV1 and BoHV-5 infections was evidenced in the sampled population, but the absence of infectious BoHVs indicate that these were not associated to the occurrence of the cases of encephalitis where rabies was the primary suspicion. In addition, no association was detected between occurrence of rabies and detection of BoHVs, since the frequency of detection of herpesvirus genomes did not significantly differ between rabies-positive and rabies-negative samples. The detection of BoHV DNA in scattered areas of the brain with no infectious virus suggests that latency may take place in different regions of the brain.

Plasma haptoglobin values in cows with different somatic cell counting in milk samples

Subclinical mastitis is an important cause of economic losses in dairy cows in Rio Grande do Sul state (southern Brazil) because the deleterious effect on the health of the cow and on the quality of milk. The difficulty of early diagnosis of this problem had led to the study of early indicators of inflammatory conditions, as acute phase proteins, mainly haptoglobin and fibrinogen, in the case of bovines. The aim of this work was to study the relationship between plasma values of haptoglobin (Hp) and fibrinogen in dairy cows with somatic cell counting (SCC) in milk for testing the hypothesis that Hp or fibrinogen would be adequate early indicators of subclinical mastitis.[...]

Nefrectomia videolaparoscópica para tratamento da dioctofimose em um cão / Videolaparoscopic nephrectomy in the treatment of canine dioctophymosis

A dioctofimose é uma afecção pouco comum em cães, causada pelo Dioctophyma renale, que ocorre com maior frequência em animais errantes. Quando um único rim é parasitado, os pacientes podem não apresentar sinais clínicos devido à compensação pelo rim contralateral. Não havendo terapia clínica efetiva para a dioctofimose, o tratamento indicado é a nefrotomia ou nefrectomia, na dependência da gravidade da lesão. Foi atendido no Hospital Veterinário da Universidade de Passo Fundo (UPF) um canino, fêmea, castrado, sem raça definida, com aproximadamente um ano e pesando 12 kg, proveniente de um abrigo de animais de rua da cidade de Passo Fundo (RS), apresentando hematúria e emagrecimento progressivo há 30 dias. Através dos exames complementares realizados, foi constatado parasitismo do rim direito por D. renale. O presente relato descreve o emprego alternativo da nefrectomia videolaparoscópica como um método seguro e efetivo para o tratamento de dioctofimose em um cão e os meios utilizados para o diagnóstico.

Dioctophymosis is a less common disease in dogs caused by Dioctophyma renale, which occurs more frequently in stranded animals. When there’s only one kidney affected, there may not be detectable symptoms because there’s compensation by the other healthy kidney. Since there is no effective clinical therapy for dioctophymosis, nephrotomy or nephrectomy are the two proposed treatments, depending on the severity of the lesion. A one-year-old spayed female mongrel dog weighing 12 kg was referred to the Veterinary Hospital at the University of Passo Fundo (UPF), brought from an animal shelter at the City of Passo Fundo, RS, Brazil, presenting hematuria and progressive weight loss for about 30 days. Complementary examination showed evidences of parasitism of the right kidney by D. renale. This report describes the alternative use of videolaparoscopic nephrectomy as a safe and effective method in the treatment of dioctophymosis in a dog and the means utilized for diagnosis.
