Tricoblastoma trabecular em gato doméstico (Felis catus domesticus, Linnaeus 1758): relato de caso

Trichoblastoma is characterized as a benign cutaneous neoplasm that originates in the trichoblastic epithelium of the hair bulb. The present report describes the case of a 4-year-old cross breed neutered male cat that had a history of a slow, freely movable, ulcerated, slow growing, solitary cutaneous nodule located on the left scapular region. Histopathological evaluation showed neoplastic cells arranged in cohesive nests or palisades with eosinophilic and scant cytoplasm. Based on the microscopic findings, a diagnosis of trabecular trichoblastoma was made. The treatment of choice consisted of total surgical excision of the mass with safe surgical margins. Tumor recurrence was not observed.O Tricoblastoma se caracteriza como uma neoplasia benigna cutânea que tem origem no epitélio tricoblástico do bulbo piloso. O presente relato descreve o caso de felino macho, sem raça definida (SRD), com histórico de nódulo solitário de crescimento lento, não aderido e ulcerado, localizado na região escapular esquerda. A histopatologia evidenciou células neoplásicas organizadas em ninhos coesos, em paliçadas com citoplasma eosinofílico e escasso, os achados foram compatíveis com a descrição de tricoblastoma trabecular. O tratamento de eleição consistiu na exérese cirúrgica total da massa com ampla margem de segurança e recidivas não foram observadas

Bubble plastic use in rats hernioplasty: Uso do plástico bolha em hernioplastias de ratos

Purpose: Despite the high frequency of hernioplasties worldwide, their complications and recurrences are still a challenge to be overcome. The search for prostheses that aim to promote the correction of hernia defects has been a challenge. For this purpose, the materials used in hernioplasties must be biocompatible, promote the formation of little or no peritoneal adhesion, possess compatible texture and flexibility, providing the necessary resistance to protect the viscera and allow the movement of the abdomen. Methods: The aim of the present study was to evaluate the effectiveness of bubble plastic (low density polyethylene, LDPE) as a material for the correction of hernia in the abdominal wall. For this, twenty male rats (Rattus norvegicus, Wistar variety) were used and divided into four groups of five animals. The animals were evaluated at 7, 15, 30 and 90 days after surgery according to clinical, thermographic and morphological parameters (macroscopic and microscopic). Results: The results showed that the bubble plastic induced inflammatory reaction in the initial period (7 day), followed by a reduction (30 day) to increase considerably at 90 days after the operation. Conclusion: So, bubble plastic can be used for temporary implants (up to 30 days)

Electrocardiographic evaluation in dogs of the Military Police of Rio de Janeiro

[Electrocardiographic evaluation in dogs of the Military Police of Rio de Janeiro.] Avaliação eletrocardiográfica em cães da Polícia Militar do Estado do Rio de Janeiro. Revista Brasileira de Medicina Veterinária, 38(Supl.2):61-66, 2016. Universidade Federal Rural do Rio de Janeiro, BR 465, Km 7, Seropédica, RJ 23897-970, Brasil. E-mail: [email protected] In Rio de Janeiro, the Army, the Military Police and the Municipal Guard use dogs for routine patrol and detection of drugs, weapons, explosives and people. The most used breeds are German Shepherd, Labrador Retriever, Malinois Belgian Shepherd, Dutch Shepherd, and Doberman. Although these animals follow a protocol of physical activity, the kennel does not include a routine cardiovascular assessment and preventive hematologic exams. Forty four adult dogs were used, 13 Labrador Retrievers, 12 Malinois Belgian Shepherds, 10 German Shepherds, eight Dobermans and five Dutch Shepherds, all clinically healthy and from the Military Police Battalion of Action with Dogs of the Rio de Janeiro state. The animals underwent computed electrocardiographic and hematological evaluations. All electrocardiographic variables were correlated with body weight. Among the five breeds evaluated in the present study, only the Labrador breed showed a positive correlation between the duration of the QT interval and weight. The other electrocardiographic variables did not show any correlation with body weight. There were differences in the electrical shaft angle in Dobermann breed dogs. Labrador breed dogs showed the highest values for P wave amplitude and the breed Dobermann the lowest values. Breed dogs Labrador and German Shepherd showed the highest values for R wave amplitude and the breed Dobermann the lowest values. The QT segment as Labrador breed dogs is directly proportional to body weight
