PURPOSE: This study attempted to investigate the frequency, duration, and risk factors of antibiotic-associated diarrhea (AAD) in infants hospitalized due to febrile urinary tract infection (UTI). This is a basic research on the probiotics used in the prevention and treatment of AAD in infants. METHODS: Medical records of the infants aged 3-6 months hospitalized in Gachon University Gil Hospital from January 2008 to September 2010 due to the febrile UTI were retrospectively reviewed. The episodes of loose or watery stool were investigated for frequency, onset, and duration. Those who had AAD and those who did not (non-AAD) were compared. The antibiotic regimens and the episodes of diarrhea were investigated in AAD group. RESULTS: Total 147 infants were included. Fifty-four (36.7%) showed AAD. Intravenous third-generation cephalosporin (3rd CS) single therapy was used for 102 patients (69.4%), the 3rd CS and non-3rd CS combination therapy for 24 (16.3%), and non-3rd CS combination therapy for 21 (14.3%). There was no significant difference in the dose of cefotaxime between AAD and non-AAD group (P=0.601). According to the antibiotic therapies above, in AAD group, there was no significant difference in the onset and duration of diarrhea respectively (P=0.717, P=0.830). Although the frequency of diarrhea was higher for the 3rd CS and non-3rd CS combination therapy subgroup with 9.25+/-5.30 times/day than the other two subgroups (7.58+/-2.97 times/day in 3rd CS single therapy subgroup, 6.75+/-4.40 times/day in non-3rd CS combination therapy subgroup), there was no statistical significance (P=0.078). CONCLUSION: AAD seems common to the infants aged 3-6 months with febrile UTI, regardless of regimen and amount of antibiotics in usual dosage. Further research on the effects of probiotics used in the prevention and treatment of AAD in infants is warranted.

PURPOSE: In spite of many reports about Helicobacter pylori infection in children with functional gastrointestinal disorders, there are few reports about the influence of H. pylori infection to functional dyspepsia and gastric motility. Therefore, we studied the influence of H. pylori infection on gastric myoelectrical activity in children with functional dyspepsia. METHODS: Between August 2006 and December 2008 upper gastrointestinal endoscopies with biopsies, the rapid urease test and/or 13C urea breath test, and electrogastrography (EGG) were performed on 63 patients with histologic chronic gastritis; patients with chronic disorders were excluded. Comparisons about gastric myoelectrical activities were made between H. pylori-positive children (n=25) and H. pylori- negative children (n=38). RESULTS: The percentage of pre- and post-prandial normogastria was relatively lower in H. pylori-positive children than H. pylori-negative children (80% vs. 65%, and 80% vs. 68%, respectively). Compared to H. pylori-negative children, H. pylori-positive children had lower postprandial predominant power (8.18+/-22.36 dB and 32.20+/-24.18 dB, respectively; p<0.01) and a lower power ratio (deltaP; delta1.28+/-6.18 vs. +.62+/-5.93, respectively; p<0.01). CONCLUSION: It was suggested that the gastric myoelectrical activity in children with chronic gastritis can be influenced by H. pylori infection. Thus, this study indicates that H. pylori infection may be predictable in children with functional dyspepsia through analyzing the EGG parameters, and treatment may be considered in H. pylori-positive children with impaired gastric activity, especially in the lower prevalence area.
