Chronic liver disease associated to copper accumulation in an american Pitbull Terrier / Hepatopatia crônica associada ao acúmulo de cobre em um cão da raça American Pitbull Terrier

Background: The liver plays a variety of essential biochemical functions such as the metabolism of carbohydrates, proteins, lipids and vitamins, the maintenance of blood glucose and bile acids synthesis. Hepatic insuffi ciency occurs when 70 to 80% of the functional liver mass is committed the liver is unable to metabolize substances on the circulation. In some cases, chronic liver disease may be associated with copper accumulation, which may occur by increased dietary intake, faults in hepatic copper metabolism or liver diseases that cause colestase. The purpose of this paper is to report a case of chronic liver disease associated with copper accumulation in a 8-month-old American Pit Bull Terrier.Case: An American Pitbull Terrier was referred to the Veterinary Teaching Hospital of the Federal University of Rio Grande do Sul with a history of abdominal distension, decreased appetite, vomiting, diarrhea, weight loss and exhaustion. On physical examination the animal presented ascites and dehydration and laboratory tests were suggestive of active liver disease. Supportive care was provided. The patient was prescribed ranitidine (2 mg/kg) VO BID for 7 days, metoclopramide (0.3 mg/kg) VO BID also for 7 days and furosemide (1 mg/kg) PO BID until further instructions while awaiting for test results. The next appointment was scheduled for ten days later but the owner came back for co

Stent placed by endoscopy for the treatment of tracheal obstruction caused by a tumor in a domestic cat / Stent placed by endoscopy for the treatment of tracheal obstruction caused by a tumor in a domestic cat

Background: Tracheal tumors are rare and may cause obstruction of the trachea. The neoplasms most commonly diagnosed in cats are lymphosarcoma, squamous cell carcinomas and adenocarcinomas. Surgical resection may provide a clinical cure for small, benign and localized tumors. For malignant neoplasia, surgery is usually palliative. Tracheal segment excision is an invasive procedure, particularly when the intrathoracic trachea is involved, and this increases the risk of stenosis, surgical suture dehiscence, necrosis and pneumothorax. Intraluminal tracheal stents have been used in dogs with tracheobronchomalacia, presenting a feasible alternative to surgery for the treatment of tracheal lumen obstruction.Case: A 11-year-old male mixed-breed cat was referred to the Veterinary Hospital of the Federal University of Rio Grande do Sul (HCV-UFRGS) with a history of appetite loss, wasting and progressive inspiratory dyspnea, for the last 30 days. The cat presenting with oral breathing. Radiography of the lateral thorax shown a radiopaque area, 1cm in diameter, superimposed in the tracheal region, close to the carina cartilage, at the fourth intercostal space.

Hemangioma and myelolipoma in the adrenal gland of a dog / Hemangioma e mielolipoma em glândula adrenal de cão

Background: Endocrine tumors are considered rare in veterinary medicine. Studies suggest that only one or two per cent of these are primary neoplasms of the adrenal glands. Concerning the histological classifi cation of these masses, the most frequently occurring malignant neoplasms in dogs are adenocarcinomas and pheochromocytomas and, among the benign tumors, adenomas are the most common. Although much rarer, hemangiomas, myelolipomas, among others, may also occur. Dogs with this kind of neoplasm could be asyntomatic or show gastrointestinal signs, pain and urinary tract infection. Adrenalectomy is the treatment of choice and could be curative in most cases. This paper reports a case of two concurrent benign, rare adrenal neoplasms in a dog, emphasizing the clinical signs, diagnosis and treatmentCase: An eight-year-old, male castrated Chow-chow, weighting twenty one kilograms, was admitted at the Veterinary Teaching Hospital of the Federal University of Rio Grande do Sul (UFRGS) with a history of intermittent vomiting and diarrhea since it was a puppy. Because of the chronicity and nonspecifi c signs, additional tests were requested. Abdominal ultrasonography showed a round mass, measuring approximately 3.7 cm x 3.2 cm, suggesting a neoplasm. Blood pressure was measured and the mean value was 152 mmHg. Laboratory tests included a complete blood count, albumin (31.62 g/L), ala

Complications associated with ovariohysterectomy using nylon tie-rap as an hemostatic method / Complicações associadas à ovariosalpingohisterectomia eletiva realizada com abraçadeira de náilon como método de hemostasia

Cases: 1- An eleven-month-old bitch was admitted at the HV-UPF nine days after OVH performed elsewhere, with omentum evisceration due to suture dehiscence. During emergency surgery both ovaries were found surrounded by nylon tie-raps and fi brous tissue adherence. Peritonitis signs were recognizable. Bilateral ovariectomy with nylon 2-0 was performed and the remaining uterus was removed. 2- A five-years-old bitch was referred to the HV-UPF ten days after OVH performed elsewhere, with apathy and suture dehiscence. Free liquid was identified around the bladder and kidneys using the ultrasound exam. Intense hemorrhage from uterine vessels was found during celiotomy. A nylon tie-rap was found loose on the abdominal cavity and another couple were found at both ovaries surrounded by fibrous tissue adherence. Bilateral ovariectomy with nylon 2-0 was performed and a blood transfusion was necessary. 3- A three-years-old bitch was admitted at the HCV-UFRGS six days after OVH performed at another institution, presenting suture dehiscence and evisceration. During emergency surgery, bladder, intestine and musculature necrosis due to the contact with sharp edged nylon tie-raps (prior placed as hemostatic devices), intense fibrous tissue adherence and peritonitis were identified. 4- A two-years-old bitch was referred to the HCV-UFRGS one year after OVH performed elsewhere, with a four-month p

Background: Routine neutering of bitches is typically carried out by ovariohysterectomy (OVH) in Veterinary Medicine, seen by many as a simple procedure. During the conventional approach the points of attachment of the uterus and ovaries are double ligated with absorbable or non-absorbable sutures or even with titanium clamps. It has been described the use of non-surgical polyamide tie-raps as a hemostatic closure method by some authors but there are few papers describing the consequenses of such use. The aim of this study is to report four cases of surgical complications associated with nylon tie-raps use on OVHs on bitches referred to the Veterinary Teaching Hospitals of the Federal University of Rio Grande do Sul (HCV-UFRGS) and Passo Fundo University (HV-UPF), both at the State of Rio Grande do Sul.Cases: 1- An eleven-month-old bitch was admitted at the HV-UPF nine days after OVH performed elsewhere, with omentum evisceration due to suture dehiscence.

Disgerminoma bilateral e hiperplasia endometrial cística com piometra em cadela

Background:  :  : Ovarian tumors are considered rare both in dogs and cats. Germ cell neoplasms correspond to approximately 15% of the cases and can be classified into dysgerminomas, teratomas and teratocarcinomas. Reports of bilateral dysgerminoma in dogs and cats are rare. The aim of this work was to describe a case of bilateral dysgerminoma and cystic endometrial hyperplasia with pyometra in a bitch by presenting the clinical, surgical, pathological and immunohistochemical findings. Case: A 10-year-old female crossbred dog was presented with a history of vomiting, apathy and purulent vulvar discharge. Physical examination revealed hyperthermia and pain was observed on abdominal palpation. Ultrasound examination revealed cystic formation and increased echogenicity inside the uterus. The animal underwent ovariohysterectomy (OHE). Macroscopically, the ovaries were multinodular, spherical to ovoid in shape, measuring 6 cm in diameter, and with a dark red color; they exhibited a firm consistency and a hemorrhagic cut surface with cystic areas and foci of necrotic tissue. At microscopic evaluation of both ovaries, the neoplasm consisted of large and polyhedral cells with amphophilic cytoplasm which were arranged in cords separated by connective tissue. The cells exhibited an anaplastic appearance, with central nuclei, large amounts of granular chromatin and one or more evident nuc

Raiva em equino no município de Porto Alegre - RS, Brasil

Background:  :  :  : rabies is a fatal zoonosis caused by a highly neurotropic RNA virus which causes neurological signs and that is distributed almost worldwide. Rabies affects domestic and wild animals and this is a disease transmitted by their bites, through which the virus present in the saliva is inoculated. In Brazil, Desmodus rotundus is the main hematophagous bat species that transmits rabies, especially to herbivores e equines. In equines, the clinical manifestation varies a lot, including both the paralytic and the furious form of the disease. The goal of this study is to describe a case of equine rabies in the city of Porto Alegre, Rio Grande do Sul, Brazil. Case: a six-year old male American Quarter Horse, which presented a clinical picture characterized by colic, depraved appetite and difficulty to move, was admitted to the Hospital de Clínicas Veterinárias of Universidade Federal do Rio Grande do Sul (HCV-UFRGS). The horse did not respond to treatment, therefore, it was submitted to exploratory laparotomy, when the moderate intestinal constipation and low intestinal motility was observed. A large colon enterotomy was performed and the intestinal contents were partially emptied. During recovery from anesthesia, the animal remained in lateral decubitus, not making any attempt to stand up. The animal did not show a favorable clinical evolution a few hours later, disp

Luxação lateral de patela em um Poodle toy

Background:  :  :  : Luxating patella is one of the most frequent conditions of the stifle joint in dogs and it can evolve into a degenerative joint disease. The occurrence of the condition can be medial or lateral, unilateral or bilateral. Its origin can be traumatic or congenital and, additionally, it may undergo genetic and environmental influence. Lateral luxation is more common in large breed dogs, and it can rarely affect medium and small breeds, whilst medial luxation is more common in small breed dogs. The classification of patellar luxation comprises four grades, according to the patellar position, clinical signs and seriousness of the bone deformities found. The diagnosis is made based on the clinical evaluation, associated with a radiographic evaluation. The present study aims at describing a case of bilateral grade 3 lateral luxating patella in a Toy Poodle dog. Case: A five-month-old female Toy Poodle dog was presented for difficulty standing and claudication of hind limbs. Orthopedic evaluation revealed internal rotation of the stifle, claudication of hind limbs during walking and jumps during trotting, in addition to a lateral grade 3 luxating patella and slight restriction of the joint motion upon extension of the right and left hind limbs. Radiographic evaluation of both stifles evidenced an ectopic (lateral) position of the right and left patellas. The anima

Esofagectomia torácica parcial no tratamento de leiomioma em esfíncter esofágico inferior de cão

Tumores esofágicos em cães são raros e dentre estes, o leiomioma é o mais relatado. Os sinais clínicos mais comuns são disfagia, regurgitação e emaciação. Foi atendido no Hospital de Clínicas Veterinárias (HCV) da Universidade Federal do Rio Grande do Sul (UFRGS) um cão da raça Dálmata, macho, oito anos, apresentando sialorreia, regurgitação, vômito, algia abdominal e emaciação. No exame endoscópico visibilizou-se massa tumoral próxima ao esfíncter esofágico inferior e fundo gástrico, e foram coletadas amostras para análise histopatológica, obtendo-se resultado compatível com leiomioma esofágico e hiperplasia gástrica. Realizou-se ressecção esofágica e anastomose esôfago-gástrica. Decorridos três dias de pós-operatório o animal foi a óbito. Na necropsia não foram observadas alterações macroscopicamente significativas e microscopicamente sugeriu-se insuficiência renal. Este relato tem o objetivo de apresentar um caso de leiomioma em esfíncter esofágico inferior em um cão, no qual a terapêutica adotada foi a exerese tumoral por toracotomia.

Tenotomia do tendão flexor profundo no tratamento da deformidade flexural adquirida na articulação interfalangeana distal em um equino

As deformidades flexurais são frequentemente vistas em animais recém-nascidos ou desenvolvem-se entre os dois primeiros anos de vida, porém, nos cavalos podem ser adquiridas em qualquer idade. Podem ser uni ou bilaterais, e geralmente se produzem como deformações flexoras das articulações interfalangeanas distais e metacarpofalangeanas. As causas relacionadas são as nutricionais, dolorosas, traumáticas, bem como a predisposição para o rápido crescimento. Foi atendido um equino, macho, castrado, sem raça definida, com oito anos de idade, 260 kg, utilizado para tração, que apresentava uma deformação flexora da articulação interfalangeana distal de grau II do membro torácico esquerdo. Pressupondo que as principais causas tenham sido a traumática e a dolorosa, foi estipulado como tratamento a tenotomia do tendão flexor digital profundo. O pós-cirúrgico constou do uso de anti-inflamatório não esteroidal, casqueamento corretivo e sessões de fisioterapia diárias. Este trabalho mostra com êxito a utilização da tenotomia do tendão flexor digital profundo para correção da deformação flexural adquirida na articulação interfalangeana distal unilateral em um equino adulto. Com o tratamento estipulado, o membro locomotor do animal retornou à sua conformação normal e após seis meses não houve sinal de recidiva, o que garantiu uma melhora significativa na sua qualidade de vida.

A efusão pericárdica em cães frequentemente é idiopática ou secundária à neoplasia. O acúmulo de líquido causa aumento da pressão intrapericárdica e alterações hemodinâmicas. Este trabalho relata o tratamento cirúrgico através de pericardiectomia parcial toracoscópica em um cão com efusão pericárdica recidivante. Acredita-se que esta seja a primeira descrição da utilização desta técnica, em caso clínico, no Brasil. Foi atendido, no Hospital de Clínicas Veterinárias da UFRGS, um cão Akita, macho, de 11 anos, com sinais clínicos compatíveis com efusão pericárdica, confirmada através de exames complementares (radiografia torácica, eletrocardiografia e ecografia). Após duas pericardiocenteses com recidiva do acúmulo de líquido, o paciente foi submetido à videotoracoscopia intercostal para realização de pericardiectomia parcial. Após 76 dias da cirurgia, o animal veio a óbito, contudo não decorrente de efusão pericárdica. No presente caso, a técnica minimamente invasiva se mostrou efetiva, sendo considerada rápida, de fácil realização e sem complicações pós-operatórias significativas.

Tenotomia do tendão flexor profundo no tratamento da deformidade flexural adquirida na articulação interfalangeana distal em um equino

As deformidades flexurais são frequentemente vistas em animais recém-nascidos ou desenvolvem-se entre os dois primeiros anos de vida, porém, nos cavalos podem ser adquiridas em qualquer idade. Podem ser uni ou bilaterais, e geralmente se produzem como deformações flexoras das articulações interfalangeanas distais e metacarpofalangeanas. As causas relacionadas são as nutricionais, dolorosas, traumáticas, bem como a predisposição para o rápido crescimento. Foi atendido um equino, macho, castrado, sem raça definida, com oito anos de idade, 260 kg, utilizado para tração, que apresentava uma deformação flexora da articulação interfalangeana distal de grau II do membro torácico esquerdo. Pressupondo que as principais causas tenham sido a traumática e a dolorosa, foi estipulado como tratamento a tenotomia do tendão flexor digital profundo. O pós-cirúrgico constou do uso de anti-inflamatório não esteroidal, casqueamento corretivo e sessões de fisioterapia diárias. Este trabalho mostra com êxito a utilização da tenotomia do tendão flexor digital profundo para correção da deformação flexural adquirida na articulação interfalangeana distal unilateral em um equino adulto. Com o tratamento estipulado, o membro locomotor do animal retornou à sua conformação normal e após seis meses não houve sinal de recidiva, o que garantiu uma melhora significativa na sua qualidade de vida.
