Manejo da deformidade flexural congênita em bezerro - aspectos cirúrgicos e patológicos / Management of a congenital flexural deformity in a calf - surgical and pathological aspects

Background: Flexural deformities are anatomical deviations, in varying degrees, of one or more joints, and may have a congenital or acquired origin. Congenital contracture of the deep digital flexor tendon (DDFT) affects newborn calves and results in hyperflexion of the metacarpal-phalangeal joint, which in severe cases means that the animal must support its own weight on its fetlock joints. The aim of this study is to report the rapid and successful result of applying bilateral total tenotomy technique on a newborn bovine that had been diagnosed with severe bilateral DDFT contracture in the thoracic limbs. Case: A 3-week-old male bovine with a history of difficulty in maintaining a quadrupedal position was attended at the Veterinary Hospital of the Federal University of Tocantins. The animal had severe bilateral locomotor alterations in the thoracic members to the point that he walked on his fetlock joints. The physical examination revealed clinical parameters within the normal range. However, the locomotor system examination showed severe flexor deformity in the bilateral metacarpal-phalangeal joints, and the limbs were being supported on the dorsal face of the fetlock joints, which presented ulcerations, and was suggestive of a shortening of the DDFT. Based on the patients history and clinical examination, as well as the severity of the tendon contractures, surgical treatment using the DDFT bilateral total tenotomy technique was decided upon. Postoperative treatment consisted of 2.5 mg/kg of enrofloxacin intramuscularly (IM), SID, for 5 days and 0.5 mg/kg meloxicam via IM, SID, for 3 days; as well as a dressing (cotton, medical bandage and a PVC mold) on the thoracic limbs to provide support and allow the animal to..(AU)

Urolitíase em novilho nelore não-castrado / Urolithiasis in steer nelore uncastrated

Neste trabalho relata-se um caso de urolitíase obstrutiva ocorrida em um bovino da raça nelore, de 1 ano e 3 meses de idade, do sexo masculino, não castrado, criado em sistema intensivo, em uma fazenda no município de São Gonçalo RJ, Brasil. O animal apresentou sintomas agudos, foi submetido ao exame clínico e ultrassonográfico. Através da necropsia foram observadas alte¬rações macroscópicas que mostravam a agressividade da patologia. O exame histopatológico foi utilizado para observar e relatar alterações microscópicas dos órgãos afetados. O referido caso trata-se de um animal não castrado, não havendo relatos como este na literatura, sendo necessários maior atenção e estudos, visto que a doença leva a sérios prejuízos econômicos(AU)

This article reports an obstructive urolithiasis in a bovine of 1 year and 3 months of age, male, Nelore, uncastrated, which was maintained in confinement in a farm in the city of São Gonçalo, RJ, Brazil. The animal presented acute symptoms and was submitted to clinical and ultrassonographic examinations. Necropsy showed macrocospic alterations that suggest the aggressiveness of the pathology. Histopathologic examination was done to report microscopic alterations of the affected organs. This case is about an uncastrated animal, with no reports like this described in the literature, requiring further attention and study, because the disease leads to serious economic losses(AU)
