Generalized systemic cryptococcosis in a dog after immunosuppressive corticotherapy

Um cão da raça Boxer, macho, com 2 anos e 11 meses de idade foi encaminhado ao hospital veterinário com histórico de distúrbio gastroentérico de dois meses de duração, apatia, hiporexia, emagrecimento progressivo e deficiência visual. Ataxia e vocalização foram observadas posteriormente. O animal estava sendo tratado em outra clínica veterinária com antibióticos e doses imunossupressoras de corticóides, direcionados ao controle de provável enterite alimentar. A morte ocorreu após cinco dias. As observações macro e microscópica revelaram tratar-se de criptococose sistêmica, atingindo trato digestório, olhos, SNC, rins, pâncreas e linfonodos. O presente relato enfatiza a infecção fúngica criptocócica quanto aos seus aspectos grastrointestinais iniciais a serem considerados no diagnóstico clínico, ressaltando a imunossupressão induzida pela corticoterapia.

Modified extracapsular extraction versus endocapsular phacoemulsification: intraoperative and immediate postoperative events

Compararam-se os eventos clínicos e as variações da pressão intra-ocular (PIO) das técnicas facoemulsificação endocapsular e extração extracapsular com modificações, no intra e no pós-operatório imediato. A facoemulsificação resultou em menor edema corneano, menor desconforto ocular e menos intercorrências no pós-operatório em relação à extração extracapsular modificada. É imperativo que se faça o monitoramento da PIO no pós-operatório, uma vez que ela ocorreu na facoemulsificação, e o uso de hipotensores oculares, quando os valores da PIO ultrapassarem os limites aceitáveis.

Considerations about electroretinography in dogs

A Eletroretinografia é técnica que acessa objetivamente a função da retina, sendo útil como meio diagnóstico auxiliar para várias oftalmopatias. Este artigo traz informações referentes às indicações, aos componentes e medidas do eletroretinograma (ERG) e à técnica do ERG flash ilustrada pelo protocolo Clássico/Standard, utilizada na Unidade de Oftalmologia do Hospital Veterinário “Governador Laudo Natel” da Faculdade de Ciências Agrárias e Veterinárias (FCAV) - Universidade Estadual Paulista (UNESP) - Campus de Jaboticabal.

Ophthalmic patterns of captive brown brocket deer (Mazama gouazoubira)

Captive brown brocket deer (Mazama gouazoubira) were manually restrained to assess tear production by the Schirmer tear test I to measure intraocular pressure by applanation tonometry, to examine ocular conjunctival epithelial cells via cytologic and histologic samples, and to survey ocular conjunctival microflora by microbiologic culture. The mean value for the Schirmer tear test I was 8.9 ± 1.8 mm/min, and the mean intraocular pressure was 15.3 ± 3.1 mm Hg. Conjunctival epithelium contained stratified pavimentous layers of cells, and the microflora consisted of predominantly gram-positive bacteria.

Utilização de implantes para o manejo de cavidades anoftálmicas

The implants are usually used after removal of the eye or its internal content, in order to maintain the orbital volume or, as in medicine, provide also the subsequent placement of ocular prosthesis. Considering prosthetic surgery procedures of high relevance in human and veterinary ophthalmology, this paper seek to review the main types of implants described in national and international literature, as well as describe the main complications when they are used in humans and veterinary patients.

Osteossarcoma mandibular em gato: Relato de Caso

The primary malignant bone tumors are uncommon in cats. Osteosarcoma is the most frequently observed in old animals. This tumors affects the appendicular skeleton, however the axial skeleton is also affected, but the bones of the head and pelvis frequent sites of injury. This paper reports a case of a cat with a history of progressive swelling in the left mandible, with follow-up period of four months. The presumptive diagnosis of osteopathy, signed by clinical and radiographic observations were confirmed by histopathology and there it is moderately productive osteoblastic osteosarcoma.

Hemangiossarcoma cardíaco em cão: Relato de caso

Cardiac tumors are relatively rare in dogs, being hemangiosarcoma (HAS) the most common neoplasia. It consists in a primary, endothelial-originated neoplasia, which frequently compromises the right atrium. The pericardial effusion, frequently identified in dogs with heart HSA is responsible for the clinical signs, such as lethargy, exercise intolerance, dyspnea, and syncope. The diagnosis is difficult and suggested mainly by the clinic, hematologic, radiographic and echocardiographic findings, and was confirmed by histopathological examination. The present study aimed to report the presence of a heart HSA in a seven year old, spayed dog presented with signs of a congestive heart failure, due to the presence of a pericardial effusion secondary to tumor, and also lung, liver and spleen metastases. Despite this uncommon association a cardiac tumor should be suspected when signs of a heart failure, with rapid decline in the clinical status abruptly occurs.

Use of a type IIB external skeletal fixator in experimental tarsocrural arthrodesis in dogs

The aim of the present study was to evaluate the usefulness of type IIb external skeletal fixators with a transarticular pin in experimental tarsocrural arthrodesis. Twelve adult mongrel dogs of both sexes, ranging in age from two to five years and weighing 12 to 25kg, were used. The configuration of the fixator consisted in the application of a transarticular Steinmann pin and of centrally threaded pins to the proximal portion of the tibia and calcaneus and to the distal portion of the metatarsal bones. In addition, Schanz pins were inserted into the medial and lateral side of the tibia and into the medial side of the metatarsal bones. Radiographs were taken 15; 30 and 45 days after surgery. Bone fusion of the treated joints were observed at 30 days in all animals, and the implants were removed after 45 days. Loosening of the centrally threaded pins was observed in all groups, especially for those applied to the calcaneus. The configuration of the external fixator proposed here was found to be satisfactory in terms of bone union for all joints during the same period, irrespective of the weight of the animal.

Síndromes oculares secundárias a infecção pelo Herpesvirus felino-1-Revisão

The feline infectious respiratory disease is the most common diagnosed infection in the veterinary clinic routine, being the Feline Herpesvirus1 the most important causal agent. Once infected, the cat will become a lifetime latent carrier, experiencing episodes of viral reactivation and spontaneous spread especially when there is a stress factor involved. This virus acts in the upper respiratory system and is also associated with eye diseases. The diagnosis is made by viral isolation and treatment protocol is based on a topic antiviral therapy, even though many of them are epiteliotoxic and may progress with intense discomfort in felines.The purpose of this paper is to describe the main ocular manifestations and syndromes seen in cats suffering from feline herpesvirus. Conjunctivitis, epithelial and stromal keratitis, corneal ulceration and indolent ulcers are the main ocular manifestations associated with viral infection, whereas symblepharon, keratoconjunctivitis sicca, proliferative keratitis and corneal sequestration are the main eye syndromes that can be observed in infected animals.
