Objective To estimate the prevalence of enuresis in children of elementary school age, to evaluate the impact of enuresis on these children and their parents, and to identify the methods and effectiveness of managing enuresis. Subjects and methods A randomly selected crosssectional study was conducted in one elementary school in each urban ward (nine schools) in Pusan, Korea. The parents of these 12 570 children aged 7± 12 years were asked to complete questionnaires which included items about the presence and frequency of enuresis, its perceived impact and management. Enuresis was de®ned as an episode of wetting occurring at least once per month. Results The overall response rate to the questionnaire was 55.8% (girls 28.2%, boys 27.6%). The prevalence of nocturnal, diurnal and combined enuresis was 9.2%, 2.2% and 1.4%, respectively. The overall prevalence of enuresis declined with age from 20.4% at 7 years old to 5.6% at 12 years old; 342 (57.0%) parents and 318 (55.6%) children were concerned about enuresis. The common self-help strategies were waking the child at night to void (38.1%) and restriction of water intake (25.7%). Of the enuretic children, only 13.7% had consulted a health worker. Conclusion The prevalence rates for enuresis in Pusan are similar to those reported from European countries. Enuretic children and their parents were moderately concerned about enuresis and the parents primarily used self-management within the family.

PurposeThis study took a retrospective approach to investigate patients with catheter-associated urinary tract infection (CAUTI) over 2 years at a single hospital's intensive care unit (ICU) to identify meaningful risk factors and causative organisms.Materials and MethodsA retrograde analysis was performed on patients with indwelling catheters between January 2009 and December 2010 in Yeouido St. Mary Hospital medical and surgical ICU. CAUTI was defined as isolated bacterial growth of 100,000 colony-forming units or more either 48 hours after transfer to the ICU if a urinary catheter was placed before the transfer or 48 hours after insertion if the catheter was inserted in the ICU. Only the patients whose culture results were negative before ICU admission were included.ResultsThere were a total of 1,315 patients with indwelling urinary catheters in our hospital's medical and surgical ICU between January 2009 and December 2010. Of these patients, 241 had positive urine culture results, and 61 had CAUTI. Using multivariate logistic regression analysis, those with diabetes were 4.55 (p<0.001) times as likely to have occurrences of CAUTI than were those without and also had a 1.10-fold (p<0.01) longer duration of an indwelling catheter. Upon urine culture, among the 61 patients with CAUTI, Escherichia coli was the most common bacterium grown; it was identified in 24 patients (38.7%).ConclusionsThe factors and causative organisms contributing to the development of CAUTI in the management of ICU patients must be considered to prevent the occurrence of UTIs in this setting.
