Management of a traumatic oronasal fistula with a prosthetic device in an 8-year-old male neutered domestic shorthair cat is described. The animal had fallen from a height of three stories at the age of 1 year. The fall had resulted in a fracture of the hard palate and a split in the palatal mucosa. Two surgical attempts to close the defect had been unsuccessful and an autopolymerizable acrylic resin prosthesis had produced unsatisfactory results. The management of the chronic traumatic fistula with a conical prosthetic device was fast, easy and efficient. The device was removed and a second one was put in place after 2 years. This method would appear particularly useful for obturation of large palatal defects that have failed to heal after attempts at surgical closure and is an alternative treatment for debilitated cats which may not be candidates for longer surgical procedures.

The vast majority of mammary tumors in cats are malignant with high metastatic and mortality rates. This study evaluated clinical, cytological and histopathological aspects of 20 cases of cat mammary masses deriving from the city of Rio de Janeiro. Data on history, macroscopic description, evidence of regional lymph node and distant metastases, clinical examination and treatment were collected. The cats were treated with unilateral mastectomy, unilateral mastectomy plus chemotherapy or chemotherapy alone. Tissues were submitted for cytological and histological evaluation. Histopathological analysis described one case of mammary hyperplasia and 19 cases of adenocarcinoma. Inadequate surgical margins were obtained in two cats while six showed evidence of microscopic invasion in other mammary glands. Multiple mammary involvement and greater tumor size (diameter over 7.05 cm) were correlated with increased chance of local metastases. Ulceration of tumors and metastases were common. These facts support the highly malignant nature of this neoplasia and emphasize the risks associated with delay in diagnosis and treatment of feline patients. In conclusion, mammary palpation should be performed routinely in the clinical practice.

The present article aims to apply two conservation techniques (convective drying and lyophilization) to the jabuticaba peels and to characterize the powders obtained regarding the physicochemical parameters and bioactive compounds, thus evaluating their effect on their composition. Convective drying of the shells was performed in an air circulation oven at 50 °C and 1.0 m.s-1 air velocity for 24h, and lyophilization was performed at -50 °C for 48 h. In natura peels and powders obtained were characterized by the following physicochemical parameters: moisture, ash, lipids, protein, crude fiber, carbohydrates, water activity, pH, acidity, reducing sugars, total soluble solids; and bioactive compounds: anthocyanins, flavonoids, total phenolic compounds and antioxidant activity by ABTS. The use of jabuticaba bark in natura and after drying in flour form are viable for the development of new products, as a way to minimize the disposal of residues produced by the agrifood industry. Through the results obtained the jabuticaba bark flour was considered to be a source of phenolic compounds with antioxidant activity and fiber and could be considered a functional food. Comparing the drying techniques used, the lyophilization stood out because it presented a better preservation of the physicochemical parameters and the bioactive compounds.

O timoma é uma neoplasia incomum em gatos domésticos que se localiza no mediastino anterior. Tumores de células da granulosa são extremamente raros em gatas e origina-se do estroma gonadal do ovário, que pode ser resultante do cordão sexual da superfície do epitélio celomático ou dos tubos mesonéfricos. Uma gata, sem raça definida, esterilizada, com dez anos de idade foi encaminhada para Clínica Veterinária particular (Gatos & Gatos Vet), Rio de Janeiro. apresentando dispnéia e efusão pleural. Foram drenados trezentos mililitros de fluido hemorrágico através da toracocentese. As avaliações radiográficas do tórax demonstraram uma massa no mediastino anterior. A biopsia incisional foi realizada através da toracotomia. O lobo pulmonar cranial esquerdo se encontrava envolto pelo tecido tumoral. A avaliação histopatológica revelou timoma epitelial de células claras com epitélio primordial associado. Foi realizado o tratamento quimioterápico utilizando o protocolo COP durante seis semanas, o qual foi curativo. Transcorridos vinte e quatro meses, a gata apresentou cios constantes, além de uma massa abdominal. Realizou-se uma biopsia excisional através da laparotomia exploratória sendo identificado um tumor de células da granulosa através de análise histopatológica. Após um ano e meio da ressecção deste tumor, a gata se apresenta em ótimo estado geral. Não foi observada nenhuma correlação entre o timoma e o tumor de células da granulosa na gata. No timoma, classificado na categoria II, tem-se como opção terapêutica à quimioterapia como tratamento único, empregando-se a ciclofosfamida, a vincristina e a prednisona. A existência do tumor de célula da granulosa deve ser considerada no diagnóstico diferencial de distúrbios comportamentais em gata, mesmo naquelas, que foram submetidas à esterilização.Descritores: timoma, tumor de células da granulosa, gato.

The present article aims to produce and evaluate the differential particle size profile of jabuticaba bark flour. The flour of the jabuticaba bark was obtained through the convective drying process, performed in an air circulation oven at a temperature of 50 °C and a speed of 1.0 m/s for 24 h. The particle size analysis was performed by sieving 50 g of jabuticaba bark flour, using a series of standardized sieves in the range of 9 to 200 mesh. The mathematical models adjusted to the experimental data were Gates-Gaudin-Schuhmann (GGS) and Rosin-Rammler-Bennet Model (RRB). From the experimental data obtained it was verified that the flour of the jabuticaba bark analyzed is in accordance with the criteria of the legislation for granulometric classification. Among the applied mathematical models, the Rosin-Rammler-Bennet (RRB) model was the best fit to the experimental data with coefficient of determination (R2) greater than 0.99, and also presenting the highest inclination angle of the line. It is noteworthy that the average diameter of the particles obtained for fine flour did not differ from the value found experimentally. And that 27.62% for a total of 50 grams of flour had a fine grain size, less than 60 mesh, which is expected and satisfactory for flour characteristics, presenting potential for use in the development of new food products.

RESUMO O Nordeste do Brasil em determinadas épocas sofre com a escassez hídrica, e a procura por água comercializada aumenta consideravelmente. Para realizar o tratamento de água, antes da comercialização, alguns proprietários adicionam o composto químico sulfato de alumínio
