Purpose : The purpose of this study is to investigate the material in middle school and high school textbooks covering child care and children's health for medically inaccurate content and to make sure that the correct information is given to students. Methods : We have examined 47 kinds of textbooks on the subjects 'Home economics' and 'Technology and home economics' published in 2007 to find out how much importance is placed on children's health and childcare and to search for incorrect definitions, inaccurate facts or insufficient explanations. We have also analyzed the credentials of the writers of these textbooks. Results : Textbooks of middle school cover psychological and physical changes during adolescence and nutrition, and those of high school cover marriage and childcare. These materials covering health made up 27.5%, 11.7% of middle & high school texts. Age definitions of neonate and infant were incorrect. Inaccurate facts were mostly about fontanelles, primitive reflexes, breastfeeding and weaning. There also were wrong informations on the umbilical cord care and developmental milestones during infancy. The childhood immunization schedules and the growth curves were not up to date. Most of the authors major in home economics and the others were school teachers. There was no evidence of any review by a medical society or an expert. Conclusions : When writing about children's health and childcare in textbooks, a board-certified pediatrician or The Korean Pediatric Society should be consulted to provide accurate medical information to middle and high school students.

Purpose : In February 2007, an outbreak of methicillin-resistant Staphylococcus aureus (MRSA) skin and soft tissue infections occurred in two newborns in the neonatal unit of Sahmyook Seoul Hospital. We performed this study to investigate the characteristics of MRSA nasal carriage among neonatal unit staffs and the effective infection control measures. Methods : Nasal swab specimens were obtained from the neonatal unit staff for the presence of MRSA. MRSA-colonized staffs were offered decolonization therapy with oral trimethoprim-sulfamethoxazole or 2% mupirocin ointment. Every 2-4months after decolonizaton, repeat nasal swab specimens were obtained. Also, samples from the neonatal unit environment and room air were collected. Results : Successful decolonization was achieved in 92% of the cases in 2 weeks after decolonization therapy, but most of the staffs were recolonized after several months. The nature of antibiotic susceptibility was changed from multi-drugsusceptible to multi-drug-resistant. The most frequently contaminated objects were dressing carts, computer keyboards, bassinets and washbowls. In environmental cultures using the settle microbe count method, the colony counts were decreased significantly at the last study period compared with the first study period in the neonatal room, breastfeeding room, service room, and dressing room (P <0.05). Conclusion : Effective control of sustained MRSA transmission within an institution may require prompt identification, treatment, and monitoring of colonized and/or infected staffs. However, nasal decolonization therapy may induce multi-drugresistant MRSA infection and had no effect on decreasing the MRSA nasal carriage rate in our study. Other factors might be more important, such as improving staff education, increasing hand hygiene practices, and environmental sterilization for controlling MRSA infections.

Purpose: Infantile constipation is one of the most common problems in pediatric gastrointestinal outpatient clinic. We planed to show the clinical feature of infantile constipation and explore the possible relationship between diets and symptoms of constipation. Methods: We analyzed the medical records and telephone questionnaire about infants under 2 years of age with constipation, who visited outpatient clinic of Department of Pediatrics, Ilsan Paik Hospital during the time from March 2002 to February 2005. Data including the symptoms and signs of constipation, diet history, and past-medical history were analyzed. Results: Total 96 infants, 40 male and 56 female, were enrolled in this study. The mean age was 9 months. Twenty-three infants were exclusively breast milk fed (BMF), 20 infants were cow's milk fed (CMF) and 53 infants had a history of mixed feeding with cow's milk and breast milk (MMF). Patients showed painful defecation (95.8%), abdominal distension (53.1%), palpable rectal stool (35.1%), hard stool (30.2%), blood-tinged stool (29.2%) and anal fissure (16.7%). Patients with exclusive cow milk feeding had prominent clinical features, such as anal fissure (p=0.03), hematochezia (p=0.04) and palpable rectal stool (p=0.025). Patients who had a history of larger intake of liquid food had a tendency to get anal skin tag (p<0.05). Conclusion: Exclusive breast milk feeding seemed important to avoid constipation with clinical significance. To educate caregivers in appropriate way of the weaning food may help the infants with constipation.

In this study, the hemolysis of Enterococcus faecalis BMSE-HMP strains, isolated from human breast milk, was investigated, and the anti-hemolytic and antimicrobial effects on multidrug-resistant (MDR) bacteria were investigated. The enzyme activity of E. faecalis BMSE-HMP 4 strains was measured, and it was found that the activities of esterase and esterase lipase were the highest. In addition, no hemolytic reaction was observed in any of the isolates. Subsequently, the anti-hemolytic activity against MDR strains causing hemolysis was evaluated. E. faecalis BMSE-HMP002 had the highest anti-hemolytic activity against Staphylococcus aureus CCARM 3855 at 75.71 ± 10.00%. The anti-hemolytic activity against Escherichia coli DC 2 CCARM 0238 and Pseudomonas aeruginosa CCARM 0223 showed that the activity of BMSE-HMP001 was highest at 76.92 ± 2.99% and 87.93 ± 1.93%, respectively. Examination of the antimicrobial effects against the MDR bacteria Staphylococcus spp., Escherichia spp., Pseudomonas spp., Salmonella spp., Klebsiella spp., Enterobacter spp., and E. faecalis BMSE-HMP strains showed antimicrobial effects against both gram-positive and gram-negative strains. Breastfeeding delivers enterococci into the intestinal tract of newborns by lactation, and its usefulness is attracting attention as it has been reported that enterococci have a potential effect on neonatal immune development. In this study, the hemolytic and antimicrobial effects of E. faecalis BMSE-HMP strains on MDR bacteria were investigated, to confirm their potential as useful lactic acid bacteria. Additional studies on the antibiotic resistance and toxicity of the E. faecalis BMSE-HMP strains, isolated in this study, are necessary to prove it safe for use.
