Abdominal ultrasonography of the healthy howler monkey (Alouatta fusca).

Abdominal ultrasonography was performed in six healthy adult brown howler monkeys Alouatta fusca and the normal ultrasonographic anatomy of the liver, gallbladder, stomach and urinary tract described for the first time. Findings were compared with post-mortem studies. The renal cortex was isoechoic to the spleen and isoechoic or hyperechoic to the liver. Kidney length and renal arterial resistive index, systolic and diastolic velocity were calculated. The liver showed a homogeneous hypoechogenic echotexture. The aim of this study was to describe the normal abdominal viscera echoanatomy providing information of normal abdominal anatomical structures in the howler monkey.

Carcinoma mamário pouco diferenciado em macaco-prego, Cebus sp. (Cebidae) / Mammary high-grade carcinoma in a monkey, Cebus sp. (Cebidae)

As neoplasias mamárias são raras em primatas não humanos, enquanto que nas mulheres apresentam alta incidência. O objetivo deste trabalho foi relatar a ocorrência e os resultados do tratamento de um Cebus sp. (fam. Cebidae) fêmea, com carcinoma mamário pouco diferenciado encaminhado ao Serviço de Atendimento de Animais Selvagens da Universidade Estadual do Centro-Oeste. À inspeção o animal apresentava aumento de volume em região mamária direita e ao exame radiográfico foram observados três pontos de radiopacidade, característicos de projétil balístico de arma de pressão, com um deles alojado ao centro da massa de tecido mamário Após estabilização, a paciente foi submetida à exérese cirúrgica de aumento de volume e o material foi encaminhado para análise histopatológica. O diagnóstico obtido foi de carcinoma de alto grau, compatível com carcinoma adenoescamoso. Após a retirada dos pontos a paciente foi encaminhada ao convívio de outros animais. Mais de 20 meses após a terapia cirúrgica não há sinais de recidiva. A paciente alimenta-se bem, convive normalmente com o grupo, sugerindo que a terapia adotada foi eficiente até o momento em alcançar qualidade de vida e aumento de sobrevida do animal.

Mammary tumors in non-human primates are rare. The aim of this paper is to report the occurrence and treatment outcomes of a female Cebus sp. (fam. Cebidae) with high-grade mammary carcinoma received at the Serviço de Atendimento de Animais Selvagens (SAAS), Universidade Estadual do Centro-Oeste. A right mammary gland nodule was identified and at radiographic examination a point of radiopacity due to gun projectile entrapped within the mammary mass was seen. After the patient stabilization, the mass was excised and submitted to histopathological examination. The diagnosis was of high-grade carcinoma, compatible with adenosquamous carcinoma. The monkey was transported to Wild Animals Treat and Receiving Center (CETAS) and introduced into a colony. More than 20 months after surgery no evidence of relapse was seen and the patient is living with the group. That suggests that the adopted therapy was effective, achieving quality of life and increased survival.

B-mode ultrasonography biometry of the Amazon Parrot (Amazona aestiva) eye.

PURPOSE: Ultrasonographic evaluation of the eye is a relatively recent addition to routine ophthalmic diagnostics in small animal ophthalmology. Some parameters for ophthalmic biometry have been established. There are few studies in clinical avian ophthalmology that describe ultrasound images of eye in some nocturnal avian species and in other birds that do not belong to the Brazilian fauna, but the psittacine family is not represented. The purpose of this study was to describe the following measurements: the distances between cornea and anterior lens capsule (D1) between the anterior and posterior lens capsule (D2), between posterior lens capsule and optic papilla (D3) and the axial length. METHOD: Sixty four transpalpebral ocular ultrasound examinations were performed on 32 Blue fronted Amazon parrots (Amazona aestiva) with no history of previous ophthalmic disease. RESULT AND DISCUSSION: The measurements were taken in sagital planes using a 10 MHz linear probe without a standoff pad. The mean values for the left eye were; D1 0.17 ± 0.03 cm, D2 0.35 ± 0.02 cm, D3 0.73 ± 0.04 cm and the axial length 1.26 ± 0.06 cm. In the right eye D1 0.17 ± 0.02 cm, D2 0.34 ± 0.02 cm, D3 0.74 ± 0.03 cm and the axial length 1.25 ± 0.05 cm. No significant statistical difference was observed among the birds or between the left and right eye. The description of these parameters will allow the veterinary practitioner to evaluate the structural changes that specific diseases may cause in these animals.
