Infecção verdadeira por Capillaria hepatica em cão / True infection by Capillaria hepatica in a dog

Background: Capillaria hepatica is a nematode, zoonotic, with worldwide distribution. The main hosts are rodents, nevertheless other mammals can be affected. Although the parasite has high affinity for the liver, it rarely causes a hepaticdisease in domestic animals and humans. The diagnosis is difficult and usually a biopsy is required. The treatment is difficult and is based in anti-helminthic and corticoid, but prevention is the best strategy against the disease. The aim of thepresent report is to describe a case of hepatic capillariosis in a dog approaching the clinical signs, diagnosis and therapeutic.Case: A 12-year-old Brazilian Terrier bitch, with a history of visit to the farm and regular hunting of rats, frogs, birds andother wild animals, was attended with hyporexia and apathy. At the physical exam the dog presented elevation of rectaltemperature, intense jaundice and abdominal pain. In the biochemical exams was noticed a slight increase in globulins anda sharp increase in alkaline phosphatase (AP), total, direct and indirect bilirubin, suggesting a liver injury. In the ultrasonographic exam, hepatomegaly with dispersed hyperechoic areas were observed, suggesting hepatic steatosis. The patientwas treated with ursodesoxicolic acid and S-adenosil metionin for 30 consecutive days, showing a clinic improvement.Two months after the end of the treatment the animal worsened, showing jaundice, ascites, motor incoordination, weakness, difficulty in food and water ingestion and changes in the mental state. In the complete blood count was observed amacrocytic hypochromic regenerative anemia, leukocytosis with neutrophilia and monocytosis and thrombocytopenia.In biochemical exams was detected decrease in creatinine and albumin and increase in alanine aminotransferase and AP,suggesting hepatopathy by biliary obstruction. There were performed exams for leishmania and ehrlichiosis that testednegative. In the ultrasonographic exam it...

Post-traumatic calcaneal tenorrhaphy associated to plaque and external skeletal fixative in dog: case report / Tenorrafia calcânea pós-trauma associada ao uso de placa e fixador esquelético externo em cão: relato de caso

The common calcaneal tendon is one of the most injured tendons in dogs. Regardless the cause, if untreated, the injury may increase permanently compromising the injured limb function. This is a case reported in a seven years old, male, 31.5 Kg, very hectic behavior, Labrador dog. The dog had been suffered a cut by walking on a wasteland. At the clinical examination, he presented claudication, knee hyperextension and tarsal hyperflexion. At the common calcaneal tendon palpation, a loss of continuity was realized characterizing a rupture. The injury was surgically treated by approximating the tendon´s stumps. Aiming to reduce the tension over the tendon, a plaque was sutured in the tendon caudal surface and the tarsocrural joint was temporarily immobilized. The calcaneal tenorrhaphy with modified Kessler suture associated to an orthopedical plaque and external skeletal fixative showed to be efficient to promote a dog´s common calcaneal tendon early repairing. The healing occurred by first intention and the injured limb had a deambulatory restoration even in the first postoperative week. Such conducts have also to be considered in calcaneal tenorrhaphies in active, heavy and/or uncooperative patients.

O tendão calcâneo comum é um dos tendões mais lesionados em cães. Independente da causa, se não tratada, a lesão pode evoluir comprometendo permanentemente a função do membro acometido. Este relato é de um caso ocorrido em um cão, macho, labrador de 31,5 kg, sete anos de idade, com temperamento muito agitado. O cão tinha histórico de ter se cortado ao andar em um terreno baldio. No exame clínico foi observada claudicação, hiperextensão do joelho e hiperflexão do tarso. À palpação do tendão calcâneo comum foi percebida a perda de continuidade caracterizando ruptura. A lesão foi tratada cirurgicamente aproximando-se os cotos do tendão. Para reduzir a tensão sobre o tendão foi suturada uma placa na superfície caudal do tendão e a articulação tarsocrural foi temporariamente imobilizada. A tenorrafia calcânea com sutura de Kessler modificada em associação ao uso de placa ortopédica e fixador esquelético externo, mostraram-se eficientes em proporcionar reparação precoce do tendão calcâneo comum de cão. A cicatrização ocorreu por primeira intenção e houve restabelecimento deambulatório do membro acometido já na primeira semana pós-operatória. Estas condutas também devem ser consideradas em tenorrafias calcâneas de pacientes ativos, pesados e ou pouco colaborativos.
