Osteopatia hipertrófica idiopática em um gatoˆipt / Hypertrophic osteopathy in a catˆien

Background: Hypertrophic osteopathy (OH) is a syndrome characterized by progressive bilateral periosteal bone neofor-mation that mainly affects the thoracic and pelvic limb bones’ metaphyses and diaphyses. In most cases, it is secondary to a chronic primary lesion located in the thoracic cavity but can be associated with an abdominal injury that has already been occurred. The occurrence of this condition without being associated with a primary lesion is considered infrequent in animals. The purpose of this report was to describe a case of idiopathic hypertrophic osteopathy in a cat with a description of clinical signs and radiographic and anatomopathological findings.Case: A male adult cat was brought to the veterinarian with an initial observation by the owner of four limbs’ volume in-crease, apathy, and reluctance to move. Upon clinical examination, the animal presented dehydration, mucosal hyperemia, hyperthermia, and bilateral edema of the thoracic and pelvic limbs. Based on the radiographic examination, a periosteal reaction with palisade-like appearance was found in the metacarpals, radios, ulna, humerus, scapulae, tibias, and fibulae. There were no significant changes in additional exams. Due to poor prognosis, the cat was euthanized and referred for necropsy and histopathological examination. All organs were examined both macroscopically and microscopically. Frag-ments were fixed in 10% formalin and routinely processed for histological slides with hematoxylin–eosin and Masson’s trichrome, and limb bones that were not fixed in formalin were macerated. Lesions were observed only in the thoracic and pelvic limbs. Macroscopically, there was a diffuse, regular, slightly firm volume increase, covered by abundant gelati-nous whitish tissue. The periosteal bone neoformations were characterized by numerous papillary projections distributed throughout the phalanges, radius, ulna, humerus, scapulae, tibia and fibulae. Histologically...

Characterization of the sheep industry in the medium northern region of Mato Grosso, Brazil / Caracterização da ovinocultura na região médio-norte de Mato Grosso, Brasil

In recent decades, the Brazilian market for sheep meat has increased substantially, and the State of Mato Grosso had thehighest growth rate in Brazil. However, information about ovine production systems in this region is lacking. This study aimed tocharacterize productive systems of sheep in the medium northern region of Mato Grosso, by application of qualitative and quantitativequestionnaires. Among 40 properties evaluated, herds there were predominately with fewer than 100 animals (82.5%, 33/40), withsemi-intensive exploration focused on meat production. Livestock sheep was a secondary economic activity in 92.5% (37/40) offarms, and sheep were kept only for family consumption in 60.0% (24/40). Poor health management resulted in the occurrenceof various diseases, and myiasis was the most frequently cited disease (65.0%, 26/40). Sheep farming has a great potential fordevelopment in Mato Grosso. However, the activity is neglected in many ways, including animal health.(AU)

Nas últimas décadas o mercado brasileiro de carne ovina aumentou substancialmente, e o estado de Mato Grosso apresentou amaior taxa de crescimento do Brasil, apesar da falta de informações sobre os sistemas de produção nesta região. Este estudo tevecomo objetivo caracterizar os sistemas de produção de ovinos da região meio-norte do Mato Grosso, utilizando um questionáriocom perguntas qualitativas e quantitativas. Dentre as 40 propriedades avaliadas foram predominantes (82,5%; 33/40) rebanhoscom menos de 100 animais, com exploração semi-intensiva, voltada para a produção de carne. A ovinocultura foi citada comoatividade econômica secundária em 92,5% (37/40) dos rebanhos e, em 60,0% (24/40) das propriedades, os animais eram mantidosapenas para consumo familiar. O manejo sanitário deficiente resultou na ocorrência de diversas doenças, sendo os casos demiíases os mais citados (65,0%; 26/40). A ovinocultura possui grande potencial para o desenvolvimento em Mato Grosso. Noentanto, a atividade ainda é negligenciada em muitos aspectos, incluindo a saúde animal.(AU)
