Influência da temperatura e do tempo de armazenamento sobre amostras de soro e plasma caninos na análise da enzima alanina aminotransferase (ALT) / Effect of temperature and storage time on canine serum and plasma samples in the analysis of enzyme alanine aminotransferase (ALT)

Este trabalho teve como objetivo avaliar a influência do tempo e da temperatura de armazenamento sobre os valores das dosagens bioquímicas de ALT em 60 amostras de soro e plasma de cães, divididas em dois grupos: GR (grupo refrigerado, a 5 °C) e GC (grupo congelado, a -20 °C), por até 96 horas analisadas em seis tempos e até 60 dias, analisadas em cinco tempos, respectivamente. O estudo mostrou que o congelamento e a refrigeração não provocaram variações entre as amostras (p< 0,005). Os dados obtidos nas dosagens bioquímicas revelaram que o soro e o plasma com EDTA mantiveram-se próximos dos valores basais, ou seja, não se alteraram significantemente ao longo do tempo de conservação e nas diferentes temperaturas estudadas.

This study aimed to evaluate the effect of time and storage temperature on the values of ALT biochemical measurements in 60 samples of serum and plasma of dogs divided into two groups: RG (refrigerated group, at 5 °C) and FG (frozen group, at -20 °C) for 96 hours analyzed at six moments and up to 60 days examined at five moments, respectively. The study showed that the effect of freezing and cooling caused no variation between the samples (p <0.005). The data showed that the biochemical serum and EDTA plasma remained near baseline, i.e ., they did not change significantly over time and at different storage temperatures.

Ovarian and uterine horn agenesis accompanied by ectopic fetal mummification in canine / Agenesia ovariana e de corno uterino acompanhada por mumificação fetal ectópica em canino

Background: The uterine horn agenesis or aplasia is a rare anomaly consisting of absence or incomplete development of the paramesonephric ducts that origin the uterine horns. This change occurs during fetal formation and may occur concomitantly to agenesis of the ovary and/or ipsilateral kidney. The extra-uterine pregnancy consists of fetal growth outside the uterine cavity and can occur as a tubal or abdominal pregnancy. We report here the case of a 7-years-old mix breed dog, attended at the Veterinary Hospital of the Federal University of Mato Grosso, with accidental diagnosis of agenesis of uterine horn and ovaries and ectopic fetal mummification. Case: A 7-years-old mix breed dog, not spayed, was attended at the Veterinary Hospital of the Federal University of Mato Grosso (HOVET-UFMT), complaining of mucous bloody vaginal discharge. The patient had regular estrus and was multiparous. There was no mating history in the last estrus neither trauma over the past months. In previous pregnancies the patient presented eutocic labors. On physical examination the dog showed apathy although it was alert, pale mucous membranes, presence of perivulvar blackish secretion and discreet abdominal enlargement. As preoperative exams, a complete blood count, liver and renal function (serum creatinine and alanine aminotransferase) were performed. It has also performed the abdominal ultrasound [...]

YU pyloroplasty for the correction of chronic hypertrophic pyloric gastropathy in canines / Piloroplastia em Y-U para a correção da gastropatia hipertrófica pilórica crônica em caninos

Background: One of the causes of delay gastric emptying is the chronic hypertrophic pyloric gastropathy, unusual disease that can occur in acquired or congenital form. It is characterized by hypertrophy of the antral mucosa, by thickening of the muscular layer, or by hyperplasia of the pylorus. The animals are presented with a history of chronic intermittent vomiting. Treatment is based on surgical correction through techniques such as pyloromyotomy or transverse or Y-U pyloroplasty. Thus, the aim was report three cases of pyloric stenosis by hypertrophy in dogs of the breeds, Fila Brasileiro, English Bull Terrier and American Pitbull Terrier, emphasizing the diagnosis and therapy instituted. Cases: All animals in this study reached the Veterinary Hospital of the Federal University of Mato Grosso with a history of chronic intermittent vomiting. The findings of physical and laboratory examinations in all animals were unspecific, with those important to rule out other causes of vomiting. Contrast radiographic evaluation revealed marked stomach distension and delayed gastric emptying, indicated gastric outflow obstruction. In one case, a video endoscopy was performed. The images reveal hyperemia of the gastric mucosa with small areas of bleeding around the stomach. It was observed intense production of gastric juice and the presence of the same reflux. In the pyloric antrum [...]

Partial unilateral radial hemimelia in feline / Hemimelia parcial unilateral de rádio em felino

Background: Hemimelia is a rare anomaly in which one of paired bone is congenital or partially absent. The etiology may be related to genetic and/or environmental factors. Clinically is observed the angulation of the affected limb, resulting in functional limitations as angular deformity, lameness and decreased range of motion. The diagnosis is based on clinical findings and radiographic examination that detects the complete or partial absence of the affected bone and angular deviations. We aim to report a case of a partial unilateral radial hemimelia in a feline diagnosed at the Veterinary Hospital of the Federal University of Mato Grosso (HOVET-UFMT). Case: We attended at the HOVET-UFMT a two years old, feline, female, domestic short hair, presenting as a complaint the presence of a friable mass in the oral cavity for a year and a deformity in the left forelimb since birth, showing swallowing difficulties, lameness and difficulty support. On clinical examination, we obeserved the left forelimb flexed and deviation in the medial direction, shortening of the limb, no crepitation during handling and evident lameness. Radiographic examination in the craniocaudal and mediolateral projections of the thoracic limbs revealed the partial absence of the radius with just a trace of the proximal radial epiphysis, shortening and a marked ulnar curvature, producing a significant deviation [...]

Description of clinical and surgical aspects of four cases of lip commissure to eyelid transposition for repair of eyelid coloboma in cats / Descrição clínico-cirúrgica de quatro casos de transposição da comissura labial para correção de coloboma palpebral em gatos

Background: Eyelid coloboma or eyelid agenesis is the most common congenital disease in cats. It can affect both the upper and the lower lids and is commonly bilateral. This congenital defect has been reported in several breeds, such as Persian and Domestic Short-Haired Cat. Generally, this defect results in inversion of the colobomatous eyelid, which can cause trichiasis and inflammatory keratitis and corneal ulceration. The only effective treatment is blepharoplasty. This paper describes the clinical and surgical aspects of four patients treated by lip commissure to eyelid transposition for the repair of eyelid coloboma using the technique described in 2010. Results of this procedure have never been reported in Brazil.Cases: Seven eyes of four cats presenting eyelid coloboma affecting up to two thirds of the eyelid were evaluated in this study. Two of the four cats were males and two were females; their average age was 3 years. All patients were admitted at the same institution, and the main issues were purulent discharge and impaired vision. Diagnosis was based on physical and ophthalmic examination. Non-ulcerative keratitis was present in all cases. Corneal ulcer was diagnosed in three patients by the fluorescein dye test. In two cats, a corneo-conjunctival dermoid was found at the temporal-dorsal region of one eye, and measured approximately 0.3 mm; and the other two [...]

Schwannoma maligno cutâneo em canino / ienne

As neoplasias primárias de nervos periféricos apresentam-se com pouca frequência em pequenos animais, sendo de aproximadamente 0,5% a incidência de tumores neurais benignos e malignos em cães. O presente trabalho tem por objetivo relatar o caso de uma fêmea canina, sem raça definida, de grande porte e onze anos de idade, atendida no Hospital Veterinário da Universidade Federal de Mato Grosso (HOVET-UFMT), apresentando neoformação em região torácica com evolução de dez meses. O nódulo media aproximadamente cinco centímetros de diâmetro, apresentava-se aderido ao subcutâneo, de formato regular e consistência firme. Ao exame clínico, não foram observadas dor à palpação ou ulceração cutânea. Após a realização dos exames pré-cirúrgicos hematológicos e de imagem (radiografia torácica), sem alterações significativas; a paciente foi encaminhada para a exérese da neoformação. Perante avaliação histopatológica, foi observada massa circunscrita por cápsula de tecido conjuntivo e células dispostas em múltiplos padrões regulares, ocasionalmente, em redemoinhos. Proliferação de células neoplásicas com moderado pleomorfismo celular, núcleo eosinofílico redondo a ovalado, nucléolo fortemente basofílico e citoplasma abundante, por vezes alongado. Anisocariose eanisocitose evidentes, além de figuras bizarras. Observou-se também a presença de infiltrado inflamatório mononuclear multifocal. Sendo assim, o diagnóstico conclusivo foi o de tumor de bainha de nervo periférico maligno (Schwannoma maligno). O procedimento cirúrgico para a extirpação da neoplasia foi realizado respeitando amplas margens de segurança. Por este motivo, mostrou-se eficaz, pois o paciente não apresentou recidivas locais, tampouco metástases a distancia em um período de 26 meses

The primary neoplasms of peripheral nerves present with low frequency in small animals, and from about 0.5 % to neural incidence of benign and malignant tumors in dogs. Herein we report one case of a large female mongrel dog, it was eleven years old, attended at the Veterinary Hospital of the Federal University of Mato Grosso (HOVET-UFMT), with formation in the thoracic region with 10 months evolution. The nodule measuring approximately five centimeters in diameter, it was attached to the subcutaneous, regular format and firm consistency. On clinical examination, there were no pain on palpation and cutaneous ulceration. After completion of hematological pre-surgical and imaging tests (thoracic radiography), with no significant change;the patient was referred to the removal of the neoformation. Before histopathological evaluation, mass was observed circumscribed by connective tissue capsule and cells arranged in multiple regular patterns occasionally in swirls. Proliferation of neoplastic cells with moderate cellular pleomorphism, eosinophilic core round to oval,strongly basophilic nucleoli and abundant cytoplasm, sometimes elongated. It presents anisocariose and obvious anisocytosis with bizarre figures. Also noted it is the presence of multifocal mononuclear inflammatory infiltrate.Thus, the conclusive diagnosis was that of a malignant peripheral nerve sheath tumor (malignant schwannoma).The surgical procedure for removal of the tumor was carried out respecting ample safety margins. For this reason, it was effective because the patient did not present local recurrence, metastases either the distance over a period of 26 months

Displasia folicular do pelo preto em canino / Black hair follicular dysplasia in canine

A displasia folicular do pelo preto (DFPP) é um distúrbio genético e raro onde os cães compelagens bi ou tricolor perdem seus pelos apenas nas áreas de pelos pretos, em idade precoce, sem predileçãoracial e sexual. É um distúrbio familiar sem tratamento atualmente, onde são caracterizadas por aglomerados demelanina nos pelos, acúmulo de melanossomas nos melanócitos (macromelanossomas) e insuficientetransferência de melanina para os queratinócitos adjacentes. Este trabalho tem como objetivo relatar um casoatendido no Hospital Veterinário da Universidade Federal do Mato Grosso (HOVET-UFMT), em uma cadela daraça Basset Hound, apresentando queda de pelo nas regiões de pelos pretos, descamação, vesículas, pápulas eprurido leve. Através do histórico, achados clínicos, associados ao tricograma e histopatologia, foi estabelecido odiagnóstico de DFPP. Não existe tratamento específico para esta dermatopatia, entretanto, a melhora do quadroclínico pode ser observada com o tratamento paliativo

The black hair follicular dysplasia in canine (BHFD) is a genetic and rare disorder where dogswith coats bi or tri lose their hair only in the areas of the black-hair at an early age, without racial and sexualpredilection. It is a family disorder with no current treatment, which are characterized by clusters of melanin inthe hair, melanosomes accumulation in the melanocyte (macromelanosomas) and insufficient melanin transfer tothe adjacent keratinocytes. This study aims to report a case treated at the Veterinary Hospital of the FederalUniversity of Mato Grosso (HOVET-UFMT), a bitch of the race Basset Hound, showing a drop of at the regionsof the black-hair, peeling, blistering, papules and mild itching. Through history, clinical findings, associated withtrichografy and histopathology, was established the diagnosis of BHFD. There is no specific treatment for thisskin disease, however, the clinical picture of the improvement can be observed with the palliative treatment

Clinical, surgical, histological and urinary aspects in six dogs with total penectomy / Aspectos clínicos, cirúrgicos, histológicos e urinários de seis cães submetidos à penectomia total

Background: In dogs, penectomy followed by uretrostomy has been little reported in the veterinary literature. These surgical procedures are indicated in cases of penile trauma and/or neoplasms as well in scrotal and preputial neoplasms. After uretrostomias is commonly observed bleeding site by approximately 4.2 days. However, studies reporting the incidence of UTI in the postoperative period of dogs submitted to penectomy, followed by scrotal urethrostomy have never been evaluated. Thus, the aim was report the evolution of dogs operated by this technique, theirs complications and the histological results, urinalysis and uroculture in patients with 60 days post-operative. Case: In the study period of 17 months (March 2013 to July 2014), nine dogs showed various neoplastic diseases involving the penis, prepuce, scrotum and testicles. In nine selected dogs to the study, only six were considered due to patient death before the minimum period used for postoperative evaluation. After surgery, the genital tract along the resected neoformation were conditioned to 10% formalin and sent to the Veterinary Pathology Laboratory for tissue analysis in light microscopy. All patients remained in hospital in the postoperative period about a week, receiving medications intravenously, execution of dressing every 12 h and evaluation of possible postoperative complications such as dehiscence suture...(AU)
