Mau Funcionamento do Sistema de Circulação Extracorpórea: Relato de Caso

Background and objectives: The introduction of extracorporeal circulation in clinical practice was decisive for the development of modern cardiovascular surgery. Addition of new procedures and equipment, however, brings inherent risks and complications. The objective of this report is to describe a malfunction of the oxygenation system and emphasize the importance of the interaction among the medical team members to prevent errors and complications. Case Report: During valve replacement and IVC correction surgery, we observed a darker shade of red in the blood on the exit of the oxygenator. Laboratory tests demonstrated severe acidosis and hypoxemia. The entire system was evaluated, but the cause of the malfunction was not found. Measures to reduce damage were successfully instituted. After the surgery, the whole system underwent technical evaluation. Conclusions: Interaction among the medical team members, early diagnosis, and immediate intervention were fundamental for a favorable outcome. © 2011 Elsevier Editora Ltda.

Osteossarcoma mandibular em gato: Relato de Caso

The primary malignant bone tumors are uncommon in cats. Osteosarcoma is the most frequently observed in old animals. This tumors affects the appendicular skeleton, however the axial skeleton is also affected, but the bones of the head and pelvis frequent sites of injury. This paper reports a case of a cat with a history of progressive swelling in the left mandible, with follow-up period of four months. The presumptive diagnosis of osteopathy, signed by clinical and radiographic observations were confirmed by histopathology and there it is moderately productive osteoblastic osteosarcoma.

Hemangiossarcoma cardíaco em cão: Relato de caso

Cardiac tumors are relatively rare in dogs, being hemangiosarcoma (HAS) the most common neoplasia. It consists in a primary, endothelial-originated neoplasia, which frequently compromises the right atrium. The pericardial effusion, frequently identified in dogs with heart HSA is responsible for the clinical signs, such as lethargy, exercise intolerance, dyspnea, and syncope. The diagnosis is difficult and suggested mainly by the clinic, hematologic, radiographic and echocardiographic findings, and was confirmed by histopathological examination. The present study aimed to report the presence of a heart HSA in a seven year old, spayed dog presented with signs of a congestive heart failure, due to the presence of a pericardial effusion secondary to tumor, and also lung, liver and spleen metastases. Despite this uncommon association a cardiac tumor should be suspected when signs of a heart failure, with rapid decline in the clinical status abruptly occurs.

Intussuscepção ileocólica associada a torção mesentérica em um cão: Relato de caso

Mesenteric torsion is a rare disease in dogs whereas it is more common to affect large animals. The main clinical signs observed are acute, such as prostration and abdominal distension which evolve to a state of shock and death. This paper reports the mesenteric torsion in a dog that was presented to veterinary care with generalized acute abdominal pain of sudden onset. At the physical examination, signs of acute abdomen, rectal temperature of 35 oC, moderate dehydration, congested mucous membrane, and prostration were detected. Emergency therapy was instituted and radiographic and ultrasound examinations were requested. The radiography showed increase in the bowel diameter and an image suggestive of intussusception. The patient was referred to emergency exploratory laparotomy and obtained a definite diagnosis of ileocolic intussusception associated to mesenteric torsion. Due to the extent of intestinal dysfunction, the patient was euthanized on the operating table.

Evaluación de la calidad de hogares de ancianos: el caso del Servicio de Salud Metropolitano Oriente, Santiago, Chile

El trabajo es parte de un estudio para la evaluación integral de los hogares de ancianos en la jurisdicción geográfica de los servicios de salud de la Región Metropolitana, de la V y VI regiones de Chile. Presenta los resultados de la evaluación implementada en el Servicio de Salud Metropolitano Oriente,cuya población es una de las más envejecidas del país. La presentación y análisis se estructuran en torno a tres ejes centrales: a) la evaluación de la dependencia física y psíquica de los 2.454 personas residentes en los hogares de ancianos (p. 57), basada en el instrumento elaborado por F.
