Urinary tract infection (UTI) is most commonly diagnosed bacterial infection in febrile infants. Renal abscess is a very rare complication of UTI in children. Early diagnosis and treatment with appropriate antibiotics are important because renal scar correlates positively with the time of treatment. Renal ultrasonography and abdominal computerized tomography facilitates an earlier diagnosis and is also useful in establishing percutaneous drainage. Extended broad spectrum antibiotics therapy alone can be effective in most types of renal abscesses in infant, but some antibiotics-resistant cases need surgical drainage or nephrectomy. We report a case of a infant UTI, that progressed to renal abscess despite early antibiotic treatment and was treated with US guided percutaneous needle aspiration.

Purpose : To set up an appropriate treatment plan for neonatal sepsis by investigating changes in pathogens and antibiotic sensitivities. Methods : The medical records of very low birth weight infants (VLBWI) admitted to the neonatal intensive care unit (NICU) of the Eulji University Hospital between January 2000 and June 2006 were retrospectively reviewed. The culture reports were analyzed for causative microorganisms and antibiotic sensitivities. Results : Among 164 neonates, 19 neonates (11.6%) had 26 episodes of culture-proven sepsis. Very late onset sepsis was the most common type. The dominant pathogens of sepsis included Klebsiella pneumoniae, Streptococcus spp., coagulase negative Staphylococcus and Enterobacter spp., and were mostly multi-drug resistant. Conclusion : For the appropriate treatment of neonatal sepsis, proper use of antibiotics through the periodic review and understanding of changes of the microorganisms and antimicrobial sensitivities is necessary to prevent multi-drug resistant microorganisms and to avoid excessive use of broad-spectrum empiric antibiotics.

Purpose : Appropriate use of antimicrobials is an essential factor to treat infectious diseases and prevent acquisition of antimicrobial resistant pathogens. This study was undertaken to search that application of computerized management program for restriction of antimicrobials use in a hospital is helpful to decrease antimicrobial use density. Methods : Antibiotics utilization committee decided to restrict the use of 16 antimicrobials(14 expensive drugs having fear of drug resistance by pathogens and additional two drugs with inappropriate using tendency). Retrospective evaluation of antimicrobial user numbers between May and July of 2004 and 2005(study group) was conducted to compare with previous use density during same period of 2002 and 2003(control group). Results : Inpatients number of control group($823.5{\pm}37.1$ persons) was more than study group($809.2{\pm}39.3$ persons, P<0.001), but, outpatients number and hospitalized duration were equal in two groups. Antimicrobial user number/100 inpatients per day of glycopeptides and antifungal agents was equal in two groups, and study group was significantly higher density than control group in the use of carbapenems, piperacillin-tazobactam and quinolones(P<0.001). But study group was significantly lower density than control group in the use of drugs with inappropriately using tendency and expensive cephalosporins having broad antimicrobial spectrum(P<0.001). Conclusion : Application of computerized management program for restriction of antimicrobials use in a hospital is effective to decrease the use density of antimicrobials with inappropriately using tendency, but it is an insufficient measures for the restricted use of other antimicrobials on the whole.

Antibiotics are used for the prevention and treatment of infections. This study aimed to investigate the patterns of dental antibiotic prescription in children and adolescents. The Health Insurance Review and Assessment Service provided data on patients who visited medical institutions. It was categorized according to year, sex, age, insurance type, dental institution, and region. Chi-square tests, Fisher's exact tests, and one-way analyses of variance were performed. Statistical analyses were performed using SAS software (ver. 9.2; SAS Institute, Cary, NC, USA). Amoxicillin and cephalosporins, the most commonly used antibiotics, accounted for approximately 96% of the prescriptions. The younger the child, the more antibiotics were prescribed for trauma, pulpitis, and dental abscesses. However, closer to adolescence, the antibiotics were primarily prescribed to manage impacted teeth and periodontal problems. Antibiotics were prescribed for 3.13 days on average. There were significant differences in the prescription rates according to age, sex, type of insurance, type of medical institution, and region (p < 0.05). This study suggested that antibiotic prescriptions should be closely monitored to ensure appropriate usage of antibiotics.

Purpose : Asymptomatic infections with positive throat culture for group A beta-hemolytic streptococci(GABHS) and high antistreptolysin O(ASO) concentration may lead to sequelae such as rheumatic fever or acute poststreptococcal glomerulonephritis. Children with asymptomatic infections were treated with oral penicillin V to evaluate the effectiveness of penicillin treatment on the asymptomatic infections. Methods : Throat culture and ASO concentration analysis were performed against healthy elementary school children. Thirty-six children with positive throat culture for GABHS and ASO concentrations of 400 IU/mL or more were divided into two groups. Twenty-two children were treated with oral penicillin V for 10 days, and the others were not treated. Eradication rate of GABHS and the change of ASO concentration between the two groups were compared after one month later. Results : Eradication rates of GABHS between treated and untreated children were 91%(20/22) and 50%(7/14) respectively(P<0.05). Children showing elevation of ASO levels more than 100IU/mL were 22%(4/18) in the treated group and 30%(3/10) in the untreated group, while children showing a decrease of more than 200IU/mL in the ASO level were 44%(8/18) and 40%(4/10) respectively. Conclusion : We confirmed the validity of penicillin treatment, because when we treated the asymptomatic children with penicillin V, the GABHS was eradicated effectively. But there was no significant difference of decrease in the ASO levels between the two groups due to long half-life of ASO or poor compliance. Treatment failure was 22% in terms of elevated ASO levels after penicillin treatment.

Purpose: The following study was performed to reveal the relationship between Clostridium difficile colitis in childhood and associated antibiotics. Methods: From January 2000 to June 2002 at Seoul National University Children's Hospital, 85 symptomatic pediatric patients who showed positive stool culture for Clostridium difficile were included. The implicated antibiotics within 2 months before stool culture were analyzed. Of the 85 patients, there were 50 males and 35 females, and their average age was 2.5 years. Results: There was a history of implicated antibiotics within 2 months in 55 cases (67%). Forty-three patients (78%) of them showed Clostridium difficile in stool culture during antibiotics treatment. The time interval between the initiation of antibiotics and stool culture ranged from one day to 7 weeks (mean 10 days) in these patients. In the remaining 12 patients, Clostridium difficile was detected after the discontinuation of antibiotics. The time interval between the discontinuation and stool culture ranged from one day to 7 weeks (mean 12 days). The associated antibiotics were cefotaxime (20 cases), amikacin(15 cases), ampicillin (13 cases), cefazolin (8 cases), vancomycin (8 cases), etc. In 31 cases, more than one antibiotics were prescribed. Conclusion: When diarrhea occurred in young children during antibiotic usage or with a past history of recent antibiotic usage, Clostridium difficile should be investigated as a cause of diarrhea for proper management.

Objectives: Antibiotics help treat Vaginitis, and prolonged usage of antibiotics can lead to resistance. Methods: This study investigates the antimicrobial activity of two types of lactic acid bacteria using essential oils. After cultivation by adding grapefruit seed extract (GSE), eucalyptus, tea tree, clove bud, cinnamon, lemongrass, thyme, and ginger oils in a specific ratio, pathogenic microorganisms, namely E. coli, C. albicans, and lactic acid bacteria were released. The number of bacteria was measured using a medium suitable for the strains. Results: The essential oils and GSE inhibited pathogenic microorganisms, and the inhibitory concentration of GSE against pathogenic bacteria (E. coli, C. albicans) was confirmed. The non-inhibitory mixing ratio was also confirmed (50 μl of eucalyptus globulus (EG) oil and 50 μl of melaleuca alternifolia oil (tea tree oil, TTO) at 200 ppm GSE (pH 5.0, 5.5, 6.0)). Conclusion: Essential oils can be considered as an alternative to antibiotics because of their antibacterial properties. They are useful as auxiliary antibacterial agents for patients under long-term antibiotic treatment.
