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)
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 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)
BACKGROUND/AIMS Our objective is to assess donor complications in all right hepatic lobe living-donor liver transplantation (LDLT) at our center. METHODS Of a total of 352 liver transplantations performed, 60 were right-lobe LDLT. Most donors (88.3%) were related to the recipients. RESULTS Mean hospital stay was 5.4+/-0.6 days. No complications occurred(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)
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 lymphoscintigraphy(More)
BACKGROUND The properties of proton pump inhibitors most investigated are related to peptic diseases and upper gastrointestinal bleeding, but their influence on the healing of sutured gastric incisions has not been assessed. In the present study we evaluated the effect of subcutaneously administered pantoprazole on the healing of sutured gastric incisions(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)
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)
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)
