Mesenteric cysts are rare intra-abdominal tumors with an incidence around one case per 100,000 hospital admissions. The clinical presentation is variable; patients may be asymptomatic or present with either acute or chronic abdominal pain. Physical examination commonly demonstrates a smooth, round and mobile abdominal mass. Differential diagnosis includes(More)
A retrospective analysis on the clinical-surgical handling of patients with enterocutaneous fistula (ECF) was performed, where an alternative surgical technique was discussed: intestinal bypass. Fistula with draining over 500 ml/24 h, which were present in 13 patients, were classified as high debit. We defined as complex, the fistula with multiple orifices,(More)
To determine long-term survival of patients with thoracic oesophageal tumor who underwent resection, and to identify possible associated prognostic factors, 58 patients underwent oesophagectomy alone (group A) and 16 combined with neo-adjuvant chemoradiotherapy (group B). Univariate and multivariate analysis of prognostic factors were performed for age,(More)
BACKGROUND/AIMS Protein-calorie malnutrition that occurs in patients with squamous cell carcinoma of the esophagus presents defined implications in surgical results. The present study aims to establish a nutritional score for malnutrition to measure the prevalence of protein-calorie malnutrition and to determine parameters with higher discriminatory power(More)
Squamous cell carcinoma of the esophagus is endemic in Rio Grande do Sul, the most southern state of Brazil, where the incidence reaches 27 out of 100,000 inhabitants per year. Palliative treatments, surgical or nonsurgical, impose lower mortality and lower costs. The choice of the best treatment for each patient depends on the neoplasia staging, and the(More)
BACKGROUND The surgical approach for patients with advanced epidermoid esophageal carcinoma should provide an effective palliative effect with morbidity ratio as low as possible. Anastomotic leakage is a frequent complication and may be responsible for both early and late morbidity and, therefore, we assessed the role of delayed cervical esophagovisceral(More)
1. The Bartha K and NIA-4 strains of Aujeszky's disease virus (ADV) were non-pathogenic for rabbits vaccinated once or twice by nasal instillation or intramuscular injection. Neutralizing antibodies were detected in 68% of the rabbits two weeks after primary vaccination and in all rabbits at challenge. 2. Challenge doses of virulent ADV greater than 10(5.0)(More)
