Acute rumenitis due to lipid overload in a bovine

ABSTRACT: The objective of this paper is to report the epidemiological, clinical, and pathological aspects of a case of rumenitis due to the ingestion of soybean oil in a bovine. The ox had access to barrels that stored soybean oil and ingested an indeterminate amount of the product. After consuming it, the animal presented hiporexia; liquid, brownish, and greasy feces; severe dehydration (12%); apathy; sternal recumbency; and death with a clinical evolution of 4 days. At necropsy, the rumen was filled with voluminous food and moderate amount of white-gray liquid with a greasy appearance. Upon microscopic examination, hydropic degeneration of the epithelium and areas of mucosal necrosis were observed in the rumen and reticulum. From these findings, we concluded that the bovine developed a state of acidosis and acute rumenitis due to excessive intake of lipids.

RESUMO: O objetivo deste trabalho é relatar os aspectos epidemiológicos, clínicos e patológicos de um caso de ruminite por ingestão de óleo de soja em um bovino. O animal teve acesso acidental a tonéis que armazenavam óleo de soja e ingeriu uma quantidade indeterminada do produto. Após o consumo, o bovino apresentou hiporexia, fezes líquidas, acastanhadas e de aspecto gorduroso, desidratação severa (12%), apatia, decúbito esternal e morte, com evolução clínica de quatro dias. Na necropsia o rúmen estava repleto por alimentos volumosos e moderada quantidade de líquido branco-acinzentado e de aspecto gorduroso. Microscopicamente, no rúmen e retículo havia degeneração hidrópica do epitélio e áreas de necrose da mucosa. A partir destes achados, concluímos que o bovino desenvolveu um quadro de acidose e ruminite aguda por consumo excessivo de lipídeos.

Testicular neoplasms in dogs in Rio Grande do Sul, Brazil / Neoplasmas testiculares em cães no Rio Grande do Sul, Brasil

Background: Testicular neoplasms are common in dogs, and their incidence is higher in older animals, and in cases of cryptorchidism. In general, they are benign and rarely metastasize. The aim of this study is to determine the frequency of testicular neoplasms in dogs in the Departament of Veterinary Pathology of the Universidade Federal do Rio Grande do Sul (SPV-UFGRS) in the period of January 2005 to December 2015. Materials, Methods & Results: Histopathological examination records of dogs conducted from January 2005 to December 2015 on SPV-UFRGS were reviewed searching for cases of testicular neoplasms in dogs. The general data of the dogs were analyzed, such as age, clinical history and clinical signs, when reported according to the requester. The classification of neoplasms in this study followed the histological criteria established by the World Health Organization. In the period studied, 4,764 biopsies were processed from male dogs, 305 (6.4%) of them were diagnosed with testicular neoplasms. The mean age range was 11.1 year-old. In 260 dogs, the neoplasms have affected a single testicle, and in 45, they were bilateral. From 305 dogs, 247 had a single neoplasm, while 58 dogs have developed more than one type of neoplasm, at once, totaling 415 diagnosis of testicular neoplasms. The most prevalent testicular neoplasms were Leydig cell tumor, followed by seminoma, and [...](AU)
