RESUMO

Un ovino adulto, macho, de la raza Dorper con histórico de regurgitación y timpanismo crónico postprandial fue sometido a exámenes de imagen. En el examen radiográfico simple de la región cervical y torácica se observó desvio ventral de la tráquea y presencia de gas en el área de proyección del esófago torácico. El esofagograma con sulfato de bario reveló retención del medio de contraste y dilatación moderada de la porción del esófago situada entre la cuarta y la novena vértebras torácicas. En la evaluación endoscópica se confirmó el diagnóstico de megaesófago segmentario, a medida que se verificó la distorsión de la porción torácica del esófago, acúmulo de fluidos y alimento y la hipomodidad en el área afectada, sin alteración de las mucosas o señal de estenosis.(AU)

An adult, male, Dorper sheep with a history of regurgitation and postprandial chronic tympanism underwent imaging examinations. In the simple radiographic examination of the cervical and thoracic region were observed a ventral deviation of the trachea and presence of gas in the area of projection of the thoracic esophagus. The barium sulphate esophagogram revealed contrast retention and moderate dilatation of the portion of the esophagus between the fourth and ninth thoracic vertebrae. In the endoscopic evaluation, the diagnosis of segmental megaesophagus was confirmed, as the thoracic portion of the esophagus was distended, fluid and food accumulation and hypomotility were present in the affected area, without any alteration of the mucosa or sign of stenosis.(AU)

RESUMO

Este estudio tuvo como objetivo evaluar la frecuencia cardíaca y respiratoria de caballos Pantaneiros sometidos a cabalgada turística en el Pantanal del Mato Grosso. Fueron evaluados 15 caballos machos castrados de la raza Pantaneira utilizados en cabalgadas turísticas. Ellos fueron mantenidos en piquetes y suplementados con pienso comercial y sal mineral. Para la medición de la frecuencia respiratoria se utilizó un fonendoscopio en la base de la tráquea, y para el análisis de la frecuencia cardíaca se utilizó el fonendoscopio en la base del corazón. Ambas mediciones se hicieron en reposo e inmediatamente después de la llegada de la cabalgada turística. El promedio de los índices respiratorios y cardíacos fueron, respectivamente, antes y después del ejercicio, de 25,87 mpm ± 1,5 y 26,4 ± mpm 1,50 y de 41,07 ± 1,38 bpm y 41,60 bpm ± 1,34. Se observó una correlación positiva entre la frecuencia respiratoria (p < = 0,01) y la frecuencia cardíaca (p < = 0,05) antes y después de la cabalgada. El caballo Pantaneiro tiene la frecuencia respiratoria superior comparada a la de la especie equina en general. El ejercicio no causó, estadísticamente, diferencias en las tasas respiratoria y cardíaca antes y después de la cabalgada turística en la región del Pantanal, lo que indica la adaptación de caballos Pantaneiros al medio ambiente y al ejercicio.(AU)

The aim of this study was to evaluate the cardiac and respiratory frequencies of Pantaneiro horses undergoing tourist horseback riding at Mato Grosso´s Pantanal. There were used 15 Pantaneiro horses, geldings, used in tourist rides. They are kept in paddocks and supplemented with commercial concentrated and mineral salt. A stethoscope was used to measure the respiratory rate at the base of the trachea and at the heart base to evaluate the heart rate. The measurements were made prior immediately after the tourist ride. The average respiratory and heart rates before and after the tourist ride were, respectively, 25.87 mpm ± 1.5 and 26.4 mpm ± 1.50 and 41.07 bpm ± 1.38 and 41.60 bpm ± 1.34. A positive correlation between respiratory rate (p <= 0.01) and heart rate (p < = 0.05) before and after the ride was observed. The Pantaneiro horse has a higher respiratory rate compared to equine species. The exercise did not cause statistically differences in the respiratory and heart rates before and after tourist horseback riding at the Pantanal region. This fact indicates the adaption of these horses to the environment and to the exercise.(AU)

RESUMO

Background: Equine lymphoma is the most common haematopoietic neoplasm in horses which can present a variety of clinical signs and course. The incidence of this neoplasia is of 0.7-3.2/100,000 horses. The major clinical manifestations depend on the degree of the organ involvement, the specific organs involved in an individual patient and duration of the disease. In general, the most common signs are weight loss, cachexia, ventral and limb subcutaneous edema, regional lymphadenopathy, depression, lethargy and recurrent fever. The purpose of the current study is to report a single case of equine lymphoma, classify this case via morphology and immunophenotyping according to the veterinary adaptation of the WHO guidelines. Case: A 19-year-old, female quarter horse showed clinical sings characterized by anorexia, weight loss, dyspnea, noisy breathing at rest, swelling in the cervical and ventral region and subcutaneous nodules. The veterinarian suspected of neoplasia. Hematological and biochemical tests were requested by the owner. The animal was euthanized due to worsening of symptoms. Macroscopically, was observed an increase of the pre-scapular and pre-crural lymph nodes and nodules in the left scapular, on the inner thigh and perineum region. On the ventral surface of the spleen was increased size of lymph nodes which showed a reddish white color. In the kidney, was observed...(AU)

RESUMO

Background: Wry Nose (Campylorrhinus lateralis) is a congenital shortening and deviation of the maxillae, premaxillae, nasal bones, vomer, and nasal septum that affects mainly foals. Intrauterine positioning as an etiology of this deformity is highly unlikely. Clinically, varying degree of premaxillar deviation is noticeable upon inspection of the foal's head. The deviation usually results in malocclusion, with no contact between the incisors of the mandible and maxilla. Some foals experience breathing difficulties or have increased respiratory sounds. This condition will not self-correct, and a decision should be made to treat the foal using reconstructive techniques or to euthanize it to prevent it from suffering. The objective of this work was to describe a case of wry nose in an adult male equine. Case: A 4-year-old, 300 kg, male SRD equine was submitted for necropsy. There was no history of respiratory problems and trouble with mastication or prehension of food. Three days before death the horse showed clinical sings characterized by no ingestion of food and water, changing behavior and locomotion, weakness, and not respond to calls, seemingly oblivious to the environment evolving into permanent recumbency and death after about 24 h of the decline. The horse was treated by a veterinarian who suspected of leucoencephalomalacea. The animal died 24 h after her condition worsened. Macroscopically, the main lesion observed was in the nose. The nasal septum was deviated to the left with the sigmoid appearance and a dorsal hump on the right side of the nasal bone. The radiographs of dorsoventral view of the jaws showing premaxillae deviated approximately 90 degrees to the left. The left premaxillae was shorter than the right premaxilla, thus creating a lesser and greater curvature of the premaxilla. Macroscopic and Microscopic lesions in the brain were not observed discarding the possibility of leucoencephalomalacea and other neurological diseases of infectious origin. Discussion: Wry nose is a relatively rare disease and have being reported in foals. In our study, it was not possible to determine the cause of this abnormality, but a computed tomography study has been associated this deformity with an underdeveloped pregnant uterus during the second half of pregnancy witch the narrow tip of the uterine horns provides only limited space for the developing cranial half of the fetus. Although the disease have been reported in young animals in which the surgical procedure in moderate to severe cases it is recommended, in the present case, the equine was four years old indicating that there is a possibility of the animal to reach adulthood, but with their commitment to quality of life. Several diseases, such as cystic degeneration, malformation of normal tissue, abscesses, fractures and neoplasms may cause thickening, malformation or deviation of the nasal septum in horse producing similar clinical sings. In the present case, the macroscopic lesions and radiography exam were useful to determinate the exact site, extent and nature of the involvement of the lesion. Despite the owner to report a clinical picture indicative of neurological disease, histological analysis of the brain ruled out this possibility. These findings indicate that wry nose disease should be kept in mind when investigating causes of deviation of the nasal septum in equines.

RESUMO

Neste trabalho, é descrito um caso de estenose hipertrófica de piloro diagnosticado por gastroscopia em um eqüino Quarto de Milha, de quatro anos de idade, que apresentava inapetência, emagrecimento progressivo, cólica, bruxismo e sialorréia. A gastroduodenite ulcerativa crônica e os espasmos prolongados foram as supostas causas da hipertrofia da musculatura circular do piloro, causando a estenose. O tratamento com substâncias antiulcerativas é paliativo e o acesso cirúrgico ao piloro no animal adulto é complexo, sendo o prognóstico duvidoso.(AU)

A case of hypertrophic pyloric stenosis diagnosed by gastroscopy was reported in a 4-years-old Quarter Horse gelding, with signs of inappetence, chronic weight loss, colic, bruxism and sialorrhea. Gastroduodenal ulceration and spasms were supposed as causes of pyloric muscular hypertrophy and stenosis. Antiulcerative medications are merely palliative and the complex surgical approach to the site of stenosis makes the prognostic to be doubtful.(AU)
