Bilateral hemimelia of radio in canine case report / Hemimelia bilateral de rádio em canino relato de caso

Hemimelia or agenesis is a congenital morphological change that may affect the appendicular skeleton. This rare anomaly is the total or partial absence of one or more bones matched. It may present unilaterally or bilaterally, with the most frequent unilateral. In dogs, the most common form of the radial hemimelia is that causes deformity of the affected limb and severe functional limitations. Was Veterinary Hospital of the Federal University of Mato Grosso (HOVET/UFMT), a canine, female mongrel, with 30 days of age, presenting deformity in thoracic limbs since birth, observed signs of lameness and difficulty support. After complete bone development the animal returned for re-evaluation and establishment of appropriate treatment. On radiographic examination, there was bilateral agenesis of radios, angulation of the ulnar cranially, fusion of carpal bones proximal and distal to the ranks, bilateral scapulohumeral dislocation and the presence of a bone structure with well-defined boundaries and rectangular articulated with the scapula. Due to good quality of life of the animal and reserved prognosis of surgery, we opted for conservation of members. The owner was recommended to keep the animal in an environment with soft ground and castration.

Hemimelia ou agenesia é uma alteração morfológica congênita que pode acometer o esqueleto apendicular. Esta anomalia rara consiste na ausência total ou parcial de um ou mais ossos pareados. Pode se apresentar de forma uni ou bilateral, sendo a unilateral mais frequente. Em cães, a forma mais comum de hemimelia é a radial, que provoca deformidade do membro afetado e severas limitações funcionais. Foi atendido no Hospital Veterinário da Universidade Federal de Mato Grosso (HOVET/UFMT), um canino, fêmea, sem raça definida, com 30 dias de idade, apresentando deformidade nos membros torácicos desde o nascimento, claudicação e dificuldade de apoio. Após o completo desenvolvimento ósseo o animal retornou para uma reavaliação e estabelecimento do tratamento adequado. O exame radiográfico revelou agenesia bilateral dos rádios, angulação das ulnas no sentido cranial, fusão dos ossos cárpicos das fileiras proximal e distal, luxação escapuloumeral bilateral e presença de estrutura óssea com limites bem definidos e formato retangular articulada com as escápulas. Devido à boa qualidade de vida do animal e ao reservado prognóstico de uma intervenção cirúrgica, optou-se pelo tratamento conservativo, sendo recomendada a castração e ambiente de piso macio.

Radiographic evaluation of the cardiac silluet using the VHS method (Vertebral Heart Size) in young and adults coatis (Nasua nasua, Linneaus 1766) living in captivity / Avaliação radiográfica da silhueta cardíaca, pelo método VHS (Vertebral Heart Size), de quatis (Nasua nasua, Linnaeus 1766) jovens e adultos mantidos em cativeiro

Radiographic examination of the toracic cavity is an usefull noninvasive method for assessment, monitoring the progress of heart disease, suggesting prognosis and guiding the treatment. The aim of this study was to evaluate the cardiac silhouette of young and adults coatis and evaluate its relationship to the number of thoracic vertebrae (VHS), the method proposed by Buchanam and Buchele (1995) for small animals. We evaluated a group of 20 coatis, divided by age: I (GI) and 8 animals aged between 4 and 5 months and group II (GII) with 12 animals over 12 months old. Based in chest radiographs and VD laterolateral right projections for determining the major axis (L) and short axis (Y) being the sum of L and S is the value obtained by ESR, the relative depth/width (D / L) chest were obtained and the results determined the type of conformation of the thorax, which results greater than 1.25 cm denote chest type deep, 0.75 to 1.25 cm chest intermediate and inferior results will 0.75cm wide chest. It was observed that the heart is alocated between the fourth and seventh pair of ribs, VHS average coatis healthy adults was 9.36 ± 0.75 and 8.06 ± 0 youth, 595 units thoracic vertebrae and the predominant conformation found was of intermediate type when compared to dogs. The mean values in this study serve as a basis for interpretation of the VHS type, however, a larger number may be requi

O exame radiográfico do tórax é um método auxiliar de avaliação não invasiva, para acompanhamento da evolução de doenças cardíacas sugerindo prognósticos e orientando tratamentos. O objetivo desse trabalho foi avaliar a silhueta cardíaca de quatis adultos e jovens em relação ao número de vértebras torácicas (VHS), pelo método proposto por Buchanam e Buchele (1995) para pequenos animais. Avaliou-se 20 quatis, separados por faixa etária em grupo I (GI) sendo 8 animais de idade entre 4 e 5 meses e grupo II (GII) com 12 animais acima de 12 meses de idade. Realizou-se radiografias do tórax nas projeções ventrodorsal e laterolateral direita para determinação do eixo maior (L) e eixo menor (S), sendo a somatória de L e S o valor obtido de VHS, a relação profundidade/ largura (P/L) torácica foram obtidas e os resultados determinaram o tipo de conformação do tórax, onde resultados superiores a 1,25cm denotaram tórax tipo profundo, de 0,75 a 1,25cm tórax intermediário e resultados inferiores à 0,75cm tórax largo. Observou-se que o coração está inserido entre o quarto e o sétimo par de costelas, o VHS médio de quatis adultos saudáveis foi de 9,36±0,75 e o de jovens 8,06 ± 0, 595 unidades de vértebras e a conformação torácica predominante encontrada foi do tipo intermediária quando comparada aos cães. Os valores médios deste estudo servirão como base para interpretação do VHS na espécie, c

Radiographic aspects of nutritional hyperparathyroidism in a cougar (Puma concolor) / Aspectos radiográfi cos do hiperparatireoidismo nutricional em uma suçuarana (Puma concolor)

Background: Secondary nutritional hyperparathyroidism (SNH) is a metabolic disease related to calcium and phosphorus homeostasis and causes generalized bone dystrophy. It occurs especially when animals are fed diets which contain proportionally high levels of phosphorus. SNH has been diagnosed in various large feline species such as jaguars, tigers, lions and leopards by means of biochemical and radiographic exams. Even though the feeding habits of these animals are well known, mistakes regarding administration of diets to animals in captivity are common, the most frequent being feeding them exclusively meat. The aim of this study was to describe the clinical and radiographic fi ndings of SNH in a cougar kept in captivity. Case: An approximately 9-month-old cougar (Puma concolor) which had been fed an exclusive meat diet was referred to the UFMT Veterinary Hospital after a period of diet correction and oral supplementation with calcium. The animal exhibited hind limb ambulation problems, poor nutritional condition and constipation. Radiographic examination revealed a slight skeletal density reduction, severe angular deformities of the hind limb bones, thickening of the femoral diaphysis, abnormal curvatures of the tibiae and calcanei, lateral displacement of the patellae and narrowing of the pelvic canal. Additionally to the skeletal alterations, there was intense colonic impac
