Presença de Dioctophyma renale em dois furões na região central do Rio Grande do Sul / Presence of Dioctophyma renale in two lesser grisons in the central region of Rio Grande do Sul

O verme gigante do rim é o único parasito conhecido capaz de atingir o parênquima do órgão. Dioctophyma renale tem distribuição mundial e é frequentemente descrito parasitando canídeos, entre outros hospedeiros acidentais. O parasito adulto habita principalmente o parênquima renal direito, de onde elimina seus ovos juntamente com a urina. Os hospedeiros definitivos adquirem o parasito ao ingerir anelídeos ou hospedeiros paratênicos (peixes e rãs) infectados. O objetivo do presente trabalho foi relatar a infecção de dois Furões-pequenos (Galictis cuja) por D. renale. Ambos os furões foram encontrados mortos na região central do estado do Rio Grande do Sul, vítimas de atropelamento. Na necropsia, foram encontrados espécimes delgados e longos, nas cavidades abdominais dos furões. Os parasitos foram identificados no Laboratório de Parasitologia da Universidade Federal de Santa Maria, campus Palmeira das Missões-RS. O achado de dois furões infectados em habitats com fortes alterações antrópicas pode ser indicativo de desequilíbrio causado pela coexistência com animais domésticos, especialmente cães, uma vez que têm sido demonstrados que cães podem ser reservatórios importantes para esta parasitose. O estudo de endoparasitos de animais silvestres é importante, a fim de compreender a ecologia, o ciclo de vida e a relação entre parasitos e hospedeiros.

The giant kidney worm is the only known parasite capable of reaching the organ parenchyma. Dioctophyma renale has a worldwide distribution and is often parasitizing canids and other accidental hosts. The adult parasite mainly inhabits the right renal parenchyma, from where it eliminates its eggs along with urine. Hosts acquire the parasite by ingesting infected annelids or paratenic hosts (fish and frogs). The objective of the present work was to report the infection of two Ferrets (Galictis cuja) by D. renale. Both ferrets were found dead in the central region of the state of Rio Grande do Sul, victims of a run over. At necropsy, thin and long specimens were found in the abdominal cavities of ferrets. The parasites were identified at the Parasitology Laboratory of the Federal University of Santa Maria, campus Palmeira das Missões-RS. The finding of two infected ferrets in habitats with strong anthropic changes may be indicative of imbalance caused by coexistence with domestic animals, especially dogs. Since it has been shown that dogs can be important reservoirs for this parasitosis. The study of wild animal endoparasites is important in order to understand the ecology, the life cycle and the relationship between parasites and hosts.

Papiloma de plexo coroide em um cão / Choroid Plexus Papilloma in a Dog

Background: Choroid plexus tumors are uncommon neoplasms derived from the neuroepithelium that covers the ventricular cavity and the central canal of the spinal cord that are characterized by papillar aspect and intraventricular growth. It occurs more commonly in dogs, but it has been reported in horses, cows, ferrets and is rare in cats. After the meningiomas and gliomas, choroid plexus tumors are the third encephalic tumors in dogs. In veterinary medicine, there are not many actual reports of this type of neoplasia, therefore, the aim of this paper was to report a case of a choroid plexus papilloma in a poodle dog. Case: A six year old dog, female, poodle, was admitted at the Veterinary Hospital of the São Paulo State University Júlio de Mesquita Filho with a complaint of seizures for 15 days, blindness and head tilt to the right side. At the neurological examination, it had depression, head tilt to the right, circling and ataxia, postural reactions deficits, absent menace response, absent light pupillary reflex with mydriasis and augmented patellar reflex. The patient was submitted to blood harvest to perform CBC count and biochemical profile (renal and hepatic), which were normal. The cerebrospinal fluid analysis presented a discrete raise of proteins. The animal was treated with phenobarbital and prednisone, under suspicion of inflammatory disease or encephalic neoplasia. The patient developed a progressive paresis of the four limbs and the seizures remained unaltered. After approximately one month of the first consultation, the dog was admitted in status epileticus, without success of control. Necropsy revealed flattening of convolutions due to cerebral edema, dilatation of the lateral ventricles (hydrocephalus) and the presence of a greyish nodule, soft and measuring 0.6 x 0.8 cm in length coming out of the fourth ventricle and extending laterally between the cerebellum and brainstem and cranially to the thalamus. At the cut of the tissue, it presented a dark area at the region of the thalamus. Neoplastic tissue was composed of cuboidal to columnar epithelial cells with oval and regular nuclei, supported by richly vascular stroma, arranged in papillae. Discussion: Choroid plexus papillomas are tumors that originate in the choroid plexus epithelium. Affected dogs usually have six or more years, earlier than most brain tumors. However, cases have been observed in younger dogs, and dogs affected by carcinoma are generally older than those affected by the papilloma. In dogs, the tumor occurs most commonly in the fourth ventricle, as in the present report, but can also occur in the third ventricle and the lateral ventricles. The clinical signs in patients with choroid plexus tumors are varied depending on the location of the tumor in the central nervous system, but may include behavioral changes, ataxia, paresis, seizures, circling, cranial nerve and proprioceptive reflexes changes. Macroscopically, the choroid plexus papilloma is a well-defined mass, expansive, granular to papillary, grayishwhite to red color. Microscopically, this tumor resembles the choroid plexus and have arboriform and vascular stroma which is coated by a single layer of cuboidal to columnar epithelial cells. The findings were consistent with choroid plexus papilloma located in the fourth ventricle.

Sebaceous epithelioma in a ferret (Mustela putorius furo)

An eight years-old male ferret presented a ventral abdominal nodular mass near the inguinal region. On clinical examination, a warty nodular mass in the abdomen was detected and the ferret was submitted to excisional biopsy by surgical procedure. At histopathology, adenomatous structures with preponderance of basophilic reserve cells, some sebocytes and showing squamous differentiation were observed. The diagnosis of sebaceous epithelioma was established based on clinical presentation and histopathologic findings. The animal recovered and at the moment no complication was reported.

Doenças da glândula adrenal em furões-europeus (Mustela Putorius Furo) / Adrenal Gland Diseases in Ferrets (Mustela Putorius Furo)

As doenças da glândula adrenal são muito comuns em furões europeus, ocorrendo a partir da meia idade. Com o intuito de descrever os principais aspectos dessas doenças e a sua ocorrência, realizou-se um estudo retrospectivo dos atendimentos a esses furões na clínica Vida Livre Medicina de Animais Selvagens, em Curitiba PR, entre janeiro de 2000 e agosto de 2004, a fim de identificar animais afetados. De 96 furões atendidos no período, quatro eram suspeitos de apresentar doença da adrenal. Os aspectos clínicos, tratamento, evolução dos casos e a literatura relacionada estão descritos neste artigo(AU)

Adrenal Gland diseases are common in ferrets, occurring in middle-aged to elderly animals. To describe main aspects and occurrence of these diseases, there have been performed a retrospective study of the ferrets examined in the Vida Livre Wild Animal Medicine animal clinic (Curitiba, state of Paraná, Brazil), between January 2000, and August 2004, in order to identify animals with adrenal diseases. From 96 ferrets seen in this period, four were suspected to present adrenal disease. Clinical features, treatment, case evolution and available literature are described in this article(AU)
