    INTRODUCTION The aim of this study was to investigate the effect of Saccharomyces boulardii treatment on preventing bacterial translocation in an obstructive jaundice animal model. MATERIALS AND METHODS Sixty adult rats were divided into five groups: group 1 - the sham-operated group; group 2 - the common bile duct ligation group; group 3 - the S. boulardii group; group 4 - the ampicillin-sulbaktam group; and group 5 the S. boulardii plus ampicillin-sulbaktam group. The saline, antibiotics and S. boulardii were given, respectively, for a 7-day period as a single dose per day via temporary orogastric intubation. Seven days following the obstructive jaundice, the animal had laparatomy under sterile conditions. Segments of ileum were removed for histopathological examination. Blood, liver, spleen and mesenteric lymph nodes were taken for microbiological culture. RESULTS Bacterial translocation rates were 0% in the sham-operated group, 83% in group 2, 42% in group 3, 42% in group 4 and 33% in group 5. Bacterial translocation significantly increased in group 2 compared to groups 3, 4 and 5 (P = 0.001). The bacterial counts (CFU/g) of group 2 were significantly higher than those of groups 3, 4 and 5 (P = 0.001). Histopathological examination of ileum specimens revealed a significant decrease in the heights of villi in groups 2-5 compared to the sham-operated group (P = 0.001). The mean villus height in groups 3 and 5 was significantly higher than that of group 4 (P = 0.001). CONCLUSIONS S. boulardii was found to be effective in the successful control of translocation and improvement of intestinal barrier function.

    A simple validated prediction rule to diagnose typhoid fever in Turkey
    (Royal Soc Tropical Medicine, 2006) Hosoglu, Salih; Geyik, Mehmet Faruk; Akalin, Serife; Ayaz, Celal; Kokoglu, Omer Faruk; Loeb, Mark
    The goal of this study was to develop a simple prediction rule for the diagnosis of typhoid fever. A model for the prediction of patients with typhoid fever at hospital admission was derived and validated by assigning weighted point values to independent predictive factors associated with a diagnosis of typhoid fever at hospital admission. Patient demographic, clinical and laboratory variables were used to compare patients with blood culture-confirmed typhoid fever with patients with fever of unknown origin. The model was derived and validated in two separate cohorts of patients from Dicle University Hospital in Diyarbakir, Turkey. A total of 371 patients were enrolled. A diagnostic index score was created using seven independent predictive factors associated with typhoid fever at hospital admission: age <30 years, abdominal. distention, confusion, leukopenia, relative bradycardia, positive Widal test and a typhoid tongue. A clinical prediction rule helped to differentiate patients with typhoid fever. (C) 2006 Royal Society of Tropical Medicine and Hygiene. Published by Elsevier Ltd. All rights reserved.
