The aim of this study was to determine whether the technique of ultrasound or radiographic image diagnosis, better supports a probable diagnosis of gastrointestinal foreign body. Thirteen dogs with presumptive diagnosis of gastrointestinal obstruction were subjected to radiological tests and ultrasound evaluation. Ultrasonography showed the presence of foreign bodies in all 13 cases, while through radiology, three foreign bodies were identified and seven were suspected of foreign body obstruction due to the intestinal distension. The foreign bodies were sonographically identified by the distal acoustic shadow and various degrees of reflection produced on the surface. In addition, the thickening of the stomach and intestinal wall in some animals, and free peritoneal fluid in a patient could be observed through ultrasound images. The findings in this study suggest that ultrasound can be us...

The aim of the present study was to describe potential risk factors for canine leptospirosis infections in patients of the Small Animal Clinic at the Veterinary School, San Marcos University, Lima, through a case-control study. Data from clinical records and serological test results from 2002 to 2007 were reviewed. Forty four cases and 394 controls were enrolled into the study. Collected data included sex, size, age, season of the year, and origin, and were analyzed by multivariable logistic regression. Risk factors related to the disease were: sex (male has double risk), size (bigger dogs have two times more risk) and age (risk increased with age).

El objetivo de este trabajo fue realizar un estudio de caso-control para evaluar factores de riesgo en la presentación de leptospirosis canina en pacientes de la Clínica de Animales Menores de la Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos, Lima. Se analizaron datos de las historias clínicas y resultados de análisis serológicos de los años 2002 al 2007. Se trabajó con un grupo caso (n=54) y un grupo control (n=394). Los datos se agruparon en las variables sexo, tamaño, edad, temporada del año y residencia, y se analizaron mediante la prueba de regresión logística. Los factores de riesgo asociados a la enfermedad fueron el sexo (el macho presenta el doble de riesgo que la hembra), el tamaño (los perros grandes presentan el doble de riesgo de presentar la enfermedad versus perros pequeños) y la edad (el riesgo es mayor con la edad).

The aim of this study was to compare the cardiac parameters of chest X-rays with aligned dorsoventral view with those of the rotated dorsoventral view of the same patient to determine the acceptable degree of rotation for these views. Fifty-three rotated dorsoventral plates from 32 canine patients were used and the parameters compared of those plates with their respective control samples or aligned dorsoventral plates. To do this, the clockface analogy test and the cardio-thoracic ratio were used and complemented with their respective right side-lateral view, allowing obtaining the angle of rotation. The results of the rotated samples were assigned to a group of 0.1º to 6º of rotation and to another group of 6º to 12º of rotation. Each cardiac chamber was evaluated with its respective control plate by the McNemar test. The group from 0.1º to 6º rotation presented a probability valu...

Canid filariasis, known as Heartworm disease, is caused by a nematode named Dirofilaria immitis, which is located in the canid´s heart producing a cardiopulmonary disease and affecting others organs like liver and kidneys. Culex, Aedes and Anopheles female flies are the intermediary hosts. The objective of this study was to determine the prevalence of D. immitis in the San Juan de Lurigancho district, close to the Rímac river. Blood samples were taken from 107 dogs in apparently good health condition from May to June 2002. Animals were randomly chosen without regard of breed and sex, and were older than 6 months old. An enzimatic commercial ELISA test (Dirochek, Synbiotic®) was used. Six positive dogs were detected, representing a frequency of 5.5±4.7% with a 95% confidence interval. No differences due to sex and environment exposition were found. In conclusion, the frequency of diro...

The objectives of the study were to describe the radiologic findings of plain radiography in animals with suspected herniated disc and to establish coincidences with the computed tomography (CT) examination. Sixteen dogs were studied, whose neurological evaluation revealed a neurological dysfunction compatible with thoracolumbar spinal cord compression and a magnitude of injury of grade III or higher. Two patients failed to show signs of disc herniation in both tests and were withdrawn from the study. Plain radiographies identified 14 animals with radiographic abnormalities consistent with a herniated disc. In 71.4% (10/14) of these cases, the results between radiographic and CT examinations coincided in the diagnosis of the presence of the disease and location of the affected intervertebral space. The radiographic findings most common in animals suspected to herniated disc type 1 were n...

El presente trabajo es una adaptación de la técnica quirúrgica de trabeculectomía para el tratamiento del glaucoma canino. Para tal fin se utilizaron 5 caninos de distintos sexos, razas y edades, y con una historia clínica de glaucoma. Se empleó la técnica quirúrgica de trabeculectomía, la cual consiste en crear una nueva vía de drenaje del humor acuoso. Los hallazgos mostraron en todos los casos una importante disminución de la presión infraocular (P<0.01). Se demostró que la trabeculectomía es una alternativa, rápida y confiable para el tratamiento resolutivo de la presión intraocular en caninos.

Para la realización de este trabajo se utilizaron 21 caninos hembras de distintas razas y edades, con una historia clínica presuntiva de piometra, cada caso fue evaluado individualmente, demostrándose la utilidad de la ecografía como método nuevo, rápido,no lesivo y altamente confiable para el diagnóstico de esta patología, adicionalmente se tomaron muestras de sangre para hematología, y se procedió a obtener los cuernos uterinos para su evaluación macroscópica e histopatológica. También se evaluó un caso aparentemente normal, tanto clínica, hematológica, ecográfica, macroscópica y microscópicamente. Los hallazgos mostraron en todos los casos crecimiento de ambos cuernos uterinos con la presencia de contenido anecógeno y/o hipoecógeno, una pared uterina engrosada e hiperecógena en la mayoría de los casos, y superficie endometrial rugosa e hipoecógena. El caso apa...

A case of a 13 year old Siamese cat whit feline aortic thromboembolism is presented. This is a devastating complication associated to hypertrophic cardiomyopathy (HCM), one of the most common heart disease in cats characterized by a significant left concentric ventricular hypertrophy.

This report shows the clinical case of a female canine patient of 1.5 molth-old diagnosed with severe patellar luxation, severe deformity of the hind limbs and inability to walk, who underwent surgical correction with satisfactory results.

This paper presents the results of two cases of prostatic omentalization conducted in two canine patients who were diagnosed with prostatic abscess. The patients were 9 and 13 years old. They presented fever, frequent urination, decay, anorexia, and abdominal pain. The ultrasound showed presence of cysts/abscesses in the prostate gland. The surgical technique was developed in a simple manner without the need of using complex equipment outside the basic surgical material. Patients recovered quickly from the surgical procedure without having post-surgery complications. It is concluded that the technique of prostatic omentalization allows the effective treatment of intra-prostatic abscesses in dogs.

It is described the clinical case of a canine patient attended 30 minutes after a car accident, with a luxofracture of the thoracic vertebra 12 and its surgical treatment by a technique of segmental fixation of the thoracic vertebrae 11, 12 13 and lumbar 1, using a Steinmann nail and surgical wires. The patient presented with paraplegia and little response to the deep pain stimulus, which, in less than 24 hours after the first evaluation was null. This demonstrated the rapid deterioration of the medullary functions detectable in the clinical examination; however, the rapid action and the diagnostic images allowed the execution of the surgical technique before 24 hours after the injury. The patient recovered his posture and the march three days after surgery, managing to walk seven days after the intervention. These results confirm the need for a timely neurological evaluation with diagno...

The persistent of the aortic right arch is a congenital anomaly that is considered difficult to treat in Peru, and therefore is presented the case of a three-month-old Cocker Spaniel canine with a history of chronic regurgitation of solid foods and poor development. At clinical examination he was alert and active but with low body condition; the esophagus on palpation at the cervical level was apparently flaccid and noticeable, and at abdominal compression it seemed to increase its volume. The contrasted radiographic image revealed a marked esophageal distension located in front of the cardiac image, which gave the diagnosis of a pre-cardiac megaesophagus. The presumptive diagnosis was the presence of the fourth persistent right aortic arch, so the surgery was suggested to the owners. Exploratory thoracic surgery was performed confirming the diagnosis and corrective surgery was performed...

La dirofilariosis canina, conocida también como “gusano del corazón”, es una parasitosis ocasionada por el nemátode Dirofilaria immitis. Se localiza en el corazón de los caninos ocasionando una enfermedad cardiopulmonar que repercute en el hígado y riñones. Los hospederos intermediarios son los mosquitos hembras del género Culex, Aedes y Anopheles. El objetivo del estudio fue evaluar la prevalencia de este parásito en los caninos del distrito de San Juan de Lurigancho (ribereño al río Rímac). Se tomaron al azar muestras de sangre de 107 perros, aparentemente sanos, mayores de 6 meses, sin distinción de raza o sexo, entre mayo a junio del 2002. Se utilizó para su diagnóstico la prueba enzimática de ELISA (Dirochek. Synbiotic®). Se hallaron 6 animales positivos, los cuales representan una frecuencia de 5.5±4.7%. No se encontraron diferencias debidas a sexo o tiempo de ...

Los objetivos del estudio fueron describir los hallazgos radiológicos de la radiografía simple en animales con sospecha de hernia discal y establecer su coincidencia con aquellos del examen tomográfico. Se estudiaron 16 pacientes caninos cuya evaluación neurológica reveló una disfunción neurológica compatible a una compresión medular toracolumbar y una magnitud de lesión de grado III o superior. Dos pacientes no presentaron sospecha de diagnóstico de hernia discal en las dos pruebas y fueron retirados. La radiografía simple identificó 14 animales con signos radiográficos compatibles a una hernia discal. De estos, el 71.4% (10/14) de los resultados de los exámenes radiográficos y tomográficos fueron coincidentes en el diagnóstico de la enfermedad y la localización del espacio intervertebral afectado. Los signos radiográficos más frecuentes en los animales sospechosos ...
