BACKGROUND Some studies have identified and selected factors that were associated with prognosis in patients with gastrointestinal fistulas, but a multivariate analysis to determine their relative importance and independent predictive value has not been done. The aim of this study was to determine independent prognostic factors for fistula closure and death(More)
OBJECTIVE To determine whether tacrolimus administered to rats, in the presence of pancreatitis induced by L-Arginine, interferes with the serum levels of amylase and glucose and the histological pattern of the pancreatic parenchyma. METHODS Forty Wistar rats were divided into four groups with 10 rats each: control group (C), tacrolimus group (T),(More)
Living donor liver transplantation (LDLT) for children and adults has gained widespread acceptance due to the severe organ shortage. LDLT provides potential recipients with timely transplantation, but this procedure engenders a potentially significant risk to the donor. This study analyzed medical, functional, and psychological donor outcomes after LDLT.(More)
Most adult and pediatric liver transplantation candidates present several metabolic disturbances that lead to malnutrition. Because malnutrition may adversely affect morbidity and mortality of orthotopic liver transplantation, it is very important to carefully assess the nutritional status of the waiting list patients. Pretransplant nutritional therapy --(More)
BACKGROUND Insulinoma is a pancreatic neuroendocrine tumor originated from pancreatic islet beta cells. Although rare, is the most common pancreatic endocrine tumor, with about four cases per million people. The preferential treatment of insulinoma is surgical.

BACKGROUND Malnutrition influences healing of gastrointestinal anastomoses. The authors hypothesize that colonic anastomotic healing is decreased by malnutrition and might be improved by preoperative feeding. METHODS Eighty adult male Wistar rats were divided into 4 groups: (1) control rats 1 (C1), fed regular chow ad libitum for 21 days; (2) malnourished(More)
BACKGROUND Insulin-like growth factor I (IGF-I) is produced almost entirely by the liver and is the main promoter of anabolic growth hormone (GH) effects on protein, carbohydrate, and lipid metabolism. IGF-I is significantly decreased in patients with liver cirrhosis. Our objective was to determine the relationship between circulating IGF-I and MELD (Model(More)
OBJECTIVE To compare safety and efficacy of propofol with midazolam for deep sedation in the colonoscopy. METHODS In a prospective way, 66 patients underwent colonoscopy--50 patients received propofol in an average dose of 3,25 mgxkg-1 and 16 patients (control group) received midazolam with total average dose of 2,05 mgxkg-1. The dose of medication was(More)
BACKGROUND The transaxillary breast augmentation (TBA) technique has gained popularity because of several advantages. However, the impact of the procedure on breast lymphatic drainage and sentinel node (SN) detection remains controversial. The objective of this study was to evaluate the lymphatic patterns and SN detection rates after TBA by using(More)
OBJECTIVE To study the effects of repeated injections of betamethasone on proteoglycan concentration in the articular cartilage of normal knees of Californian rabbits of both sexes. METHODS Eighty animals were randomly divided into eight groups of ten animals each. Three control groups (saline solution injected or not) and five study groups -(More)
