Purpose:The aim of this study was to determine the prevalence of asymptomatic nasopharyngeal carriages in children using a multiplex reverse transcriptase-polymerase chain reaction (mRT-PCR) assay kit. Methods:We obtained nasopharyngeal swabs from 33 children without any underlying disease from July 25 to July 28, 2008. The children were free from the signs of respiratory tract infections at the time of sampling. DNA was extracted from the swabs and subjected to multiplex RT-PCR using a primer set for the detection of pneumococci ($Seeplex^{(R)}$ PneumoBacter ACE Detection Seegene, Seoul, Korea). The amplified PCR products were separated on 2% agarose gels and stained with either ethidium bromide or screen tape system (Lab901 Scotland, UK). Results:A total of 33 children (male, 15 female, 18) aged between 3.2 and 16.3 (median, 8.2) years were included in this study. The mRT-PCR detected colonized bacteria (Streptococcus pneumoniae, Hemophilus influenzae, Chlamydia pneumoniae, and Bordetella pertussis) in 30 children (90.9%). Of these, 13 children (39.4%) showed more than 2 bacteria: 12 children were positive for 2 bacteria (S. pneumoniae and H. influenzae) and 1 child was positive for 3 bacteria (S. pneumoniae, H. influenzae, and C. pneumoniae). Conclusion:mRT-PCR was found to be a sensitive tool for the detection of asymptomatic nasopharyngeal carriages. Clinical significances of the bacteria detected by mRT-PCR will have to be evaluated in the future.

Objectives & Methods : In order to evaluate the in vitro synergic effects or Eunkyo-san which is a traditional poly-herbal formula that has been used in the treatment of respiratory diseases in oriental medicine, and quinolone antibiotics, rufloxacin (RUFX) and iprofloxacin(CPFX), experimentation was designed to determine minimal inhibitory concentration(MIC), $MIC_{50}\;and\;MIC_{90}$ of single use of quinolones and concomitant treatment with Eunkyo-san against 5 strains of aerobic gram negative bacteria, Escherichia coli, Klebsiella peumoniae, Hemophilus influenzae, Citrobacter freundii and Pseudomonas aeruginosae. Result : In the case of aerobic gram negative bacteria, the MIC, $MIC_{50}\;and\;MIC_{90}$ against Klebsiella peumoniae and Citrobacter freundii significantly decreased in concomitant-treated groups with Eunkyo-san compared to those of single-treated groups of RUFX and CPFX, respectively. However, no significant changes were demonstrated against Echerichia coli, Hemophilus influenzae and Pseudomonas aeruginosae. Conclusion : According to these results, concomitant use of Eunkyo-san against some strains of aerobic gram-negative bacteria dramatically increases in vitro antibacterial activity of RUFX and CPFX, and the increase and selectivity of antibacterial activities against these strains is attributable to Eunkyo-san, and not RUFX or CPFX activity.

In order to evaluate the in vitro synergic effect of Mahwangyounpae-tang which was a traditional poly-herbal formula has been used in the treatment of respiratory diseases in oriental medicine, and quinolone antibiotics, ciprofloxacin (CPFX), the minimal inhibitory concentration (MIC), $MIC_{50}$ and MIC90 of single use of quinolones and concomitant treatment with Mahwangyounpae-tang against 5 strains of aerobic gram negative bacteria, Escherichia coli, Klebsiella peumoniae, Hemophilus influenzae, Citrobacter freundii and Pseudomonas aeruginosae. The obtained results were as follows : In the case of aerobic gram negative bacteria, the MIC, $MIC_{50}$ and $MIC_{90}$ against Klebsiella peumoniae and Pseudomonas aeruginosae was significantly decreased in concomitant treated groups with Mahwangyounpae-tang compared to those of single treated groups of CPFX, respectively. However, no significant changes were demonstrated against Echerichia coli, Hemophilus influenzae and Citrobacter freundii. According to these results, it is considered as the in vitro antibacterial activity of CPFX was dramatically increased by concomitant use of Mahwangyounpae-tang against some strains of aerobic gram negative bacteria and the increase and selectivity of antibacterial activities against strains were chosen by the selectivity of Mahwangyounpae-tang not CPFX activity.

Acute epiglottitis is one of the common conditions of upper airway obstructions in children. The clinical course is not only fulminant but possibly fatal, resulting from massive swelling of supraglottic structures especially epiglottis caused by Hemophilus influenzae. This is so because early recognition and careful airway management is always desired. Numerous reports in the literature reveals that a majority of cases occurs mainly in young children under six years of age, however, recent reports of acute epiglottitis in adult is increasing. We present a series of acute epiglottitis in adult and a review of the literature. We also discuss the differences between acute epiglottitis in adult and in children in terms of clinical course, causative organism, management and the results of treatment.

Purpose : There is no scientific basis for an immunization policy for children with renal disease who have increased risk of infection in Korea. As an initial step in approaching this problem, this survey of pediatric nephrologists was undertaken to determine the current recommendations of practicing pediatric nephrologists Methods : Questionnaires were sent to the members of Korean Society of Pediatric Nephrology via mail and E-mail. The questionnaire was designed to obtain information about the immunization practice of basic vaccination schedule for nephrotic syndrome, the side effects after vaccination and the immunization practice about recommended vaccines for children with renal disease. Results : Questionnaires were sent to 56 pediatric nephrologists. 35 replies were received (response rate: 62.5%). Almost of the respondents (82.8%) reported practicing at university hospital. All respondents reported modified vaccination schedule. 65.7% of the respondents immunized nephrotic children with live vaccines some time later after discontinuation of corticosteroids treatment and 57.1% of respondents immunized them with killed vaccines during medication of low doses of corticosteroids. Respondents experienced relapse of nephrotic syndrome after vaccination are nine, lack of vaccine efficacy are three and infection by organisms of live vaccines are two. 71.4% of respondents reported vaccinating children with renal disease for hepatitis B, pneumococcus and influenza during medication of low doses of corticosteroids. But There is few difference of the rates of respondents vaccinating them for Hemophilus influenzae type b between during medication of low doses of corticosteroids and after discontinuation of corticosteroids treatment (45.7% us 42.9%). Almost of respondents reported vaccinating renal failure children without immunosuppression for hepatitis B, pneumococcus, influenza and H. influenzae type b ($54.3{\sim}77.1%$). Conclusion : Pediatric nephrologists practiced modifying vaccination schedules for children with renal disease in Korea and there was variation according to the progression of disease and the doses of corticosteroids. It is necessary to establish the immunization guideline for children with renal disease through the prospective studies.
