Diagnosis of Dioctophyma renale using ultrasonography and microscopy: a case report / Diagnóstico de Dioctophyma renale utilizando a ultrassonografia emicroscopia em um cão em Belém do Pará, Brasil: relato de caso

Dioctophyma renale is classified as a cosmopolitan zoonotic helminth, belonging to Nematoda class and Dioctophymoidea superfamily. Dogs are considered definitive hosts, suffering with large kidney damage, and the disease diagnosis can be done through ultrasound, x-ray and light microscopy. The aim in this paper was to report the sonographic and microscopic aspects of a canine affected by Dioctophyma renale. Dark colored urine evolving to hematuria and abdominal pain was the main symptoms observed in the animal. Performing urinalysis it was verified D. renale eggs. Ultrasonography could observe total destruction of the right renal parenchyma, hyperechoic structures of cylindrical and rounded shape bounded by the renal capsule, suggesting the presence of the parasite, while the left kidney had normal size. The animal was submitted to nephrectomy, confirming the worm presence, measuring 31.8 cm long. It can be stated that ultrasound and light microscopy are highly effective to establish a definitive diagnosis of Dioctophyma renale.

O dioctophyma renale é classificado como um helminto zoonótico cosmopolita, pertencenteà classe de Nematoda e superfamília de Dioctophymoidea. Os cães são considerados hospedeirosdefinitivos, e sofrem grande dano renal. O diagnóstico pode ser feito através de ultrassom, raiosx e microscopia de luz. O objetivo deste trabalho foi relatar os aspectos ultrassonográficose microscópicos de um canino afetado por Dioctophyma renale. A urina de cor escura comevolução para hematúria e dor abdominal foram os principais sintomas observados no animal.Foi realizada a urinálise, onde foi evidenciado os ovos de D. renale. Na ultrassonografia pôde-seobservar destruição total do parênquima renal direito, estruturas hiperecoicas de forma cilíndricae arredondada delimitadas pela cápsula renal, sugerindo a presença do parasita, enquanto o rimesquerdo estava com seu tamanho normal. O animal foi submetido à nefrectomia, confirmandoa presença do verme, medindo 31,8 cm de comprimento. Pode-se afirmar que o ultrassome a microscopia de luz são altamente eficazes para estabelecer um diagnóstico definitivo de Dioctophym arenale.

Gravidez ectópica em gata associada à mumificação fetal / Ectopic pregnancy in cat associated with a fetal mummification

The objective of this study was to report a case of ectopic pregnancy in a domestic feline. It conducted aphysical examination and blood count, biochemistry, x-ray, abdominal ultrasound and electrocardiogram. Bloodcount and serum biochemistry was not observed any changes. In radiographic examination, there was increasedradiopacity in the cranial region to the heart, heart silhouette presented is positioned horizontally to thethoracic floor. In cranial abdomen was noticed accidentally, a radiopaque structure, well-defined, out of thetopography of uterus, suggesting fetus macerated ectopic. In ultrasound examination was not observed anystructure within the uterus. The animal was referred to surgery, to carry out the exploratory laparotomy andovariosalpingohisterectomy. the mummified fetus was adhered to the omentum, located in the cranial region left abdomen was removed.(AU)

Casuística das afecções do sistema reprodutor de cães diagnosticados pela ultrassonografia no Hospital Veterinário da UFRA (Belém/PA) em 2015 / Ultrasonographic survey related to reproductive system of dogs treated at the Veterinary Hospital of UFRA (Belém/PA) in 2015

Ultrasonography is a powerful ally of the medical clinic, assisting in the definition of gynecologicaldiagnoses and andrological pathologies. The aim of this study was to present the ultrasonographic survey of themain reproductive disorders of dogs at the Diagnostic Imaging Sector of the Veterinary Hospital at FederalRural University of Amazon from January to December 2015. Abdominal ultrasound examinations of 200canines of both sexes and different age groups were performed, and the data referring to the diagnoses ofreproductive alterations were recorded and tabulated in spreadsheet and organized in percentages according tothe prevalence. 887 ultrasound examinations were performed where 200 dogs presented diseases related to thereproductive organs, representing 22.5% of the casuistry. From the aid of this diagnostic method, it wasevidenced that the main ilnesses that affect reproductive system of dogs attended by this institution werepyometra and benign prostatic hyperplasia.(AU)
