RESUMO

Background: The chemodectoma is a rare neoplasm that originates from chemoreceptors located mainly in the aortic body,and carotid body and sinus, and responsible for detecting variations in blood pH, oxygen pressure and carbon dioxide. Dogsof brachiocephalic breeds and aged between 7 and 15 years have greater propensity. A neoplasm involves infiltrative growthin the vessels at the heart base, which leads to Congestive Heart Failure (CHF). The definitive diagnosis is performed byhistopathological and/or immunohistochemical examination. The aim was to report a case of chemiodectoma in a dog,showing the diseases clinical characteristics.Case: A 13-year-old male undefined breed dog was examinated in the medical clinic of small animal of Veterinary Hospital,Federal Rural University of Pernambuco (UFRPE) with respiratory effort, hyporexia, and edema in face, cervical, ventralthorax and thoracic limbs, with thirty days evoluted. About physical examination, we observed cachexia, orthopneic position, cyanosis and edema with a positive Godet sign, as well as 8% dehydration degree. Thoracic auscultation presentedmixed dyspnea and muffled heart sounds. Chest radiography detected an radiopacity increase in pulmonary section andmetastatic neoplastic process associated with pleural and pericardial effusion. Fluid therapy with lactated ringer and posteriorthoracentesis in the right hemithorax region was performed for greater respiratory comfort for the patient. Hematologicalcount and biochemical profiles stated normochromic normocytic anemia, relative and absolute lymphopenia, thrombocytopenia, as well as increased alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The patient diedafter 12 hours when was submitted to necroscopic examination and histopathological evaluation. An infiltrative tumor ofcardiac base was observed invading the light of the right atrium, obstructing the venous return, as well as a large thrombus...(AU)

RESUMO

A nutrição é extremamente importante em animais cardiopatas, pois pode tornar a progressão da doença mais lenta. Sua principal atuação é evitar que os animais apresentem caquexia. A insuficiência cardíaca causa uma incapacidade cardiovascular de manutenção da circulação sanguínea normal, onde o volume de sangue bombeado é insuficiente, causando alterações no débito cardíaco. A nutrição pode ser utilizada como adjuvante na terapia de animais cardiopatas, pois retardara progressão e minimiza os medicamentos necessários, melhorando a qualidade e expectativa de vida dos pacientes. O objetivo deste trabalho é abordar a insuficiência cardíaca congestiva (ICC) em cães e seus principais tratamentos nutricionais.

Nutrition is extremely important in heart disease animals as it can make disease progression slower. Its main action is to avoid that the animals present cachexia; Heart failure causes a cardiovascular inability to maintain normal blood circulation, in which the volume of blood pumped is insufficient, causing changes in cardiac output. Nutrition can be used as an adjuvant in the therapy of heart disease patients, because rather slows progression and minimizes the necessary medications, improving the quality and life expectancy of patients. The objective of this paper is to address congestive heart failure (CHF) in dogs and their main nutritional treatments.

RESUMO

The ingestion of detritus by sea turtles results in high mortality and morbidity. The objective of this study was to describe the characteristics of free-living sea turtles that ingested anthropogenic inorganic detritus in comparison to those that did not. A total of 186 necropsy files were analyzed in marine turtles from the beaches of the Microregion dos Lagos, Rio de Janeiro. Among the turtles that ingested detritus, the mean turtle was female and cachectic, with a carapace length of 36,6 cm, detritus accumulated in the large intestine, and fecal compaction. It seems most likely that's low food transit, combined with the multiplicity of ingestion, favored the accumulation of detritus. This ingestion resulted in cachexia associated with fecal compaction, since the greatest accumulation was in the large intestine. The intake of detritus by turtles was not punctual but continuous. These studies demonstrated the vulnerability of these animals to environmental pollution.

RESUMO

PURPOSE: To assess antioxidant effects of açaí seed extract on anorexia-cachexia induced by Walker-256 tumor. METHODS: A population of 20 lab rats were distributed into four groups (n=5): Control Group (CG), which only received tumor inoculation. Experimental Group-100 (EG-100), with animals submitted to tumor inoculation and treated with seed extract in a 100 mg / ml concentration through gavage. Experimental Group-200 (EG-200), with animals submitted to tumor inoculation and treated with seed extract in a 200 mg / ml concentration. Placebo Group (GP), which received tumor inoculation and ethanol-water solution. We analyzed proteolysis, lipid peroxidation, tumor diameter and weight. RESULTS: Lipid peroxidation was representative only in the cerebral cortex, where there was more oxidative stress in rats treated with the extract (p = 0.0276). For proteolysis, there was less muscle damage in untreated rats (p = 0.0312). Only tumor diameter in treated rats was significantly lower (p = 0.0200) compared to untreated ones. CONCLUSIONS: The açaí seed extract showed no beneficial effect on the general framework of the cachectic syndrome in lab rats. However, some anticarcinogenic effects were observed in the tumor diameter and weight.(AU)

RESUMO

There are very few reports of lymphoma in sheep in the literature. Therefore, the aim of the present study was to report the prevalence of this disease among sheep cared for in the Clinic of Cattle in the Campus Garanhuns of the Federal Rural University of Pernambuco (UFRPE). The results were obtained from a four year old sheep (weight 40 kg) that had been reared in a semi-intensive system. The owner reported that he had acquired this animal three months earlier from another herd and that, one month later; he had noticed that the animal was apathetic, no appetite and distanced itself from the herd. The animal was treated unsuccessfully on the farm. The animal exhibited clinical signs of apathy, tachycardia, cachexia and anorexia, as well as ruminal and intestinal hypomotility. The hemogram showed evidence of leukocytosis by neutrophilia, with the presence of deteriorated leukocytes in the blood smear. The serology (IDGA) for the enzootic bovine leukosis virus was negative. The ultrasound confirmed severe lung disease. The animal died after seven days. In the necropsy there was a mass in the subcutaneous tissue adhered to chest sternal there was a notable increase in the volume adhered in the external caudal subcutaneous region, with nodular characteristics and a whitish coloration. Identical, although smaller, nodulations were visualized in the serous membrane of the reticulum and the abomasum, with metastases in the kidneys, omentum, mesenteric lymph nodes, diaphragm, heart and lungs. The histopathology revealed atypical mantle structures,with multiple vacuoles and interspersed fibrous stroma. The tumoral cells were small, round, basophilic, with scarce cytoplasm and a large, round nucleus, with hyperchromatic qualities, dense chromatin and rare mitosis. The results of the present study confirm that this was a case of atypical lymphosarcoma in the sheep in question.

Os relatos na literatura de linfoma em ovinos são escassos, logo o objetivo deste trabalho é relatar a ocorrência dessa doença em uma ovelha atendida na Clínica de Bovinos, Campus-Garanhuns/ UFRPE. Os achados foram obtidos de uma ovelha mestiça de quatro anos, pesando 40 kg, criada em sistema semi-intensivo. O proprietário relatou que adquiriu esse animal há três meses de outro rebanho e que há dois observou que o animal ficou apático, com perda do apetite e separado do rebanho, foi medicado na propriedade sem sucesso. Clinicamente apresentou um quadro de apatia, taquicardia, caquexia, anorexia, bem como hipomotilidade ruminal e intestinal. No hemograma evidenciou-se leucocitose por neutrofilia, com presença de leucócitos degenerados no esfregaço sanguíneo. A sorologia (IDGA) para vírus da Leucose Enzoótica Bovina foi negativa. Além desses achados, a ultrassonografia revelou um comprometimento pulmonar grave. O animal veio a óbito após sete dias. Na necropsia observou-se uma massa no tecido subcutâneo, aderida à região torácica caudal esternal, firme com características nodular e de coloração esbranquiçada. Nodulações idênticas e de tamanhos menores foram visualizadas na serosa do retículo e abomaso, com metástases nos rins, omento, linfonodos mesentéricos, diafragma, coração e pulmão. A histopatologia revelou estruturas atípicas disposta na forma de manto, com múltiplos vacúolos, com estroma fibroso entremeado. As células tumorais caracterizam-se por serem pequenas e arredondadas, basofílicas, com citoplasma escasso, núcleo grande e redondo, hipercromático, com cromatina densa e com raras mitoses. Estes achados indicam uma forma de linfoma espontâneo em ovelha.
