Objective : Shunt infection is a common complication while treating hydrocephalus. The antibiotic-impregnated shunt catheter (AISC) was designed to reduce shunt infection rate. A meta-analysis was conducted to study the effectiveness of AISCs in reduction of shunt infection in terms of age, follow-up time and high-risk patient population. Methods : This study reviewed literature from three databases including PubMed, EMBASE, and Cochrane Library (from 2000 to March 2019). Clinical studies from controlled trials for shunt operation were included in this analysis. A subgroup analysis was performed based on the patient's age, follow-up time and high-risk population. The fixed effect in RevMan 5.3 software (Cochrane Collaboration) was used for this meta-analysis. Results : This study included 19 controlled clinical trials including 10105 operations. The analysis demonstrated that AISC could reduce the infection rate in shunt surgery compared to standard shunt catheter (non-AISC) from 8.13% to 4.09% (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.40-0.58; p=0.01; I2=46%). Subgroup analysis of different age groups showed that AISC had significant antimicrobial effects in all three groups (adult, infant, and adolescent). Follow-up time analysis showed that AISC was effective in preventing early shunt infections (within 6 months after implant). AISC is more effective in high-risk population (OR, 0.24;95% CI, 0.14-0.40; p=0.60; I2=0%) than in general patient population. Conclusion : The results of meta-analysis indicated that AISC is an effective method for reducing shunt infection. We recommend that AISC should be considered for use in infants and high-risk groups. For adult patients, the choice for AISC could be determined based on the treatment cost.

Purpose: Febrile urinary tract infection (UTI) is one of the commonest bacterial infections in children. The purpose of this study is to investigate the clinical characteristics of the first episode of febrile UTI occurring in children over 5 years compared to those in infants younger than a year. Methods: We retrospectively reviewed the medical records of 10 patients over 5 years, having febrile UTI, and 25 controls under 1 year. Clinical characteristics including symptoms at admission, the time interval between symptom onset and hospital visit and/or diagnosis, duration of fever, urinalysis, and other laboratory and imaging test results were compared between the two groups. Results: Most patients in the control group showed only high fever at the time of presentation to the hospital. However, 60% of the case group had fever along with gastrointestinal (GI) symptoms such as abdominal and flank pain, vomiting, as well as relatively mild pyuria. The case group showed a longer duration between symptom onset and hospital visit and/or diagnosis. Conclusions: Delay in diagnosis and initiation of treatment of UTI increases the risk of permanent renal scarring and associated complications. Therefore, early diagnosis and treatment of febrile UTI is vital for very young infants, as well as children considering that febrile UTI could be an important cause of febrile illness in children over 5 years.

The purpose of this paper was to concisely review the practical changes in MeHg concentrations in fetus and offspring throughout gestation and suckling from our recent animal and human studies. In the animal study, adult female rats were given a diet containing 5ug/g Hg (as MeHg) for 8 weeks. Then they were mated and subsequently given the same diet throughout gestation and suckling. On embryonic days 18, 20, 22 and at parturition, the concentrations of Hg in the brains of fetus were approximately 1.5-2.0 times higher than those in the mothers. However, during the suckling period Hg concentrations in the brain rapidly declined to about 1/10 of that during late pregnancy. Hg concentrations in blood also decreased rapidly after birth. In human study, Hg concentrations in red blood cells (RBC-Hg) in 16 pairs of maternal and umbilical cord blood samples were compared at birth and 3 months of age after parturition. RBC-Hg in the umbilical cords was about 1.6 times higher than those in the mothers at parturition. However, all the infants showed declines in Hg concentrations throughout the breast-feeding period. RBC-Hg at 3 months of age was about half that at birth. Both the animal and human studies indicated that MeHg exposure to the fetus might be especially high but it dramatically decreases during the suckling period. Therefore, close attention should be paid to the gestation rather than the breast-feeding period to avoid the risk of MeHg to human infants.

Objectives: Postpartum depression(PPD) is a kind of serious problem which influences on the postpartum woman, her family and infant. It has been known to be caused by many factors and some depression scales have been used to assess the degree of PPD. Edinburgh Postpartum Depression Scale(EPDS) recently began to be used for screening for PPD.Methods: The subjects were 46 women who admitted for postpartum treatment in Oriental Hospital of Woosuk University from May 2000 to December 2000. In this study, we used EPDS and Beck Depression Inventory(BDI) to assess the degree of PPD, and we researched the related factors of PPD. Results: 13 women(28.3%) in the high risk group by EPDS and 7 women(15.2%) in depression - severe depression group by BDI were diagnosed as PPD among the 46 women. There was significant correlation between Epds score and BDI score. The mean score of EPDS was higher in normal delivery group than caesarean delivery group, higher in primiparae group than multiparae group, and higher in the group who delivered female infants than male infants. But there were not significant differences. And there was not significant correlation between EPDS score and age.Conclusions: These results suggest that PPD is quite frequent at postpartum period and it is necessary to treat for PPD. It is important for clinicians to pay attention to the related factors of PPD as well as to recognize and treat PPD.

Purpose: We aim to assess the Bayley Scales of Infant and Toddler Development, third edition (Bayley-III), Adaptive Behavior (AB) and Social-Emotional (SE) scales at 18 to 24 months of corrected age (CA) to examine their associations with school-age cognitive and behavioral outcomes in children born preterm. Methods: Eighty-eight infants born with a very low birth weight (<1,500 g) or a gestational age of less than 32 weeks who were admitted to the neonatal intensive care unit from 2008 to 2009 were included. Of the 88 children who completed school-age tests at 6 to 8 years of age, 37 were assessed using the Bayley-III, including the AB and SE scales, at 18 to 24 months of CA. Correlation, cross-tabulation, and receiver operating characteristic analyses were performed to assess the longitudinal associations. Results: A significant association was observed between communication scores on the Bayley-III AB scale at 18 to 24 months of CA and the Korean version of the Wechsler Intelligence Scale for Children (K-WISC) full-scale intelligence quotient (FSIQ) at school age (r=0.531). The total behavior problem scores of the Korean version of the Child Behavior Checklist (K-CBCL) at school age were significantly negatively related to the Bayley-III SE and AB scales but not to the cognitive, language, or motor scales. Conclusion: Our findings encourage AB and SE assessments during the toddler stage and have important implications for the early identification of children in need of intervention and the establishment of guidelines for follow-up with high-risk infants.

Purpose: The aim of this study was to investigate the clinical characteristics of Respiratory syncytial virus (RSV) infection during the neonatal period to provide information that is useful in clinical practice and suggest extension of the palivizumab administration. Methods: Neonates admitted to the National Health Insurance Service Ilsan Hospital neonatal intensive care unit due to respiratory symptoms and for whom multiplex reverse transcription-polymerase chain reaction and multiplex real time-polymerase chain reaction tests were performed between October 2011 and May 2016 were included in this study. Medical records were retrospectively reviewed, and data was collected for 156 neonates. Results: Among the 156 neonates, RSV was detected in 114 (73.1%), non-RSV in 25 (16%), and no virus in 17 (10.9%). The majority were full term infants (92.4%) and peak incidence of RSV infection was in January. Post-natal care center infection was more common in the RSV group (46.6%) than that in the other virus groups (24%, P=0.0243). Clinical symptoms were severe in the RSV group in contrast to that in the non-RSV or others groups. The RSV group frequently needed oxygen therapy (P=0.0001) and the duration of hospital stays were longer (P=0.0001). Conclusion: RSV is a significant cause of respiratory infection in neonates and the severity is higher in contrast to that with other viral causes of infection. Infants in post-natal care centers have a high-risk of developing RSV infections; therefore, palivizumab administration may be considered in this group to prevent hospitalization and reduce the duration of hospital stay.

Purpose: Recent reports showed that plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) could be a useful biomarker of intravenous immunoglobulin (IVIG) unresponsiveness and coronary artery lesion (CAL) development in Kawasaki disease (KD). The levels of these peptides are critically influenced by age; hence, the normal range and upper limits for infants and children are different. We performed an age-adjusted analysis of plasma NT-proBNP level to validate its clinical use in the diagnosis of KD. Methods: The data of 131 patients with KD were retrospectively analyzed. The patients were divided into 2 groups-group I (high NT-proBNP group) and group II (normal NT-proBNP group)-comprising patients with NT-proBNP concentrations higher and lower than the 95th percentile of the reference value, respectively. We compared the laboratory data, responsiveness to IVIG, and the risk of CAL in both groups. Results: Group I showed significantly higher white blood cell count, absolute neutrophil count, C-reactive protein level, aspartate aminotransferase level, and troponin-I level than group II (P<0.05). The risk of CAL was also significantly higher in group I (odds ratio, 5.78; P=0.012). IVIG unresponsiveness in group I was three times that in group II (odds ratio, 3.35; P= 0.005). Conclusion: Age-adjusted analysis of plasma NT-proBNP level could be helpful in predicting IVIG unresponsiveness and risk of CAL development in patients with KD.

The Low Birth Weight infant birth rate in this country is a little more than 15 percent and is being increased. The survival rate of Low Birth Weight infant is over 90 percent and recently the rate runs is getting. However, because of the high risk of Low Birth Weight infant for handicap in growth, a preventive nursing intervention program for Low Birth Weight infant and their mother is considered to be necessary. Touch and massage, thus sensory stimulation has been considered to be important ensuring a normal growth of Low Birth Weight infant During the past decades sensory stimulation program has been used for premature and Low Birth Weight infants. Recently a study on the sensory stimulation for Low Birth Weight infants has bee n done in this country. Mother and infant relationship has a great influence on child's development. Especially, mother and infant interaction during one year after birth plays important role in child's social. affective and cognitive developments. But in the study of Low Birth Weight infants, the mother and infant interaction has been rare yet. However, there was no study effectiveness of the sensory stimulation on mother and infant interaction. In this respect, this study based on the importance of the nursing intervention, is intended to measure the effectiveness of the massage therapy in the aspects of weight, daily feeding amount, cortisolurine stress hormone and mother and infant interactions. This study has been conducted on the nonequivalent control group pretestposttest design in quasi experimental basis and Low Birth Weight infants from NICU of two Medical University Hospitals located in Taegu Metropolitan were selected in experimental group of 21 infants and control group of 20 infants. Data has been collected from May 1, 1999 to September 5, 2000. For the experimental group Field's sensory stimulation(tactile and kinesthetic stimulation) was applied 2 times a day for 10 days(10:00 - 11:00 hours in the morning and 19:00 - 20:00 in the afternoon) by nurse and mother. The electronic indicator scale (Cas Co. Korea) was used to measure infant's body weight. To determine urine cortisol concentration level under stress, rad immuno assay method was used. And to determine mother and infant interactions during feeding, tools developed by Kim Mi-Ye (1999) were used. Collected data were analyzed with SAS program using x-test, t-test, paired t-test and repeated measures ANOVA. Findings were as follows : 1. For the daily mean weight gain, the experimental group showed little higher than the control group, even though, there was no Statistically significant differences between two groups. 2. For the amount of daily mean feeding, the experimental group showed little higher than the control group, while there was no Statistically significant differences between two groups. 3. The level of wine cortisol concentration was increased in both groups, while no Statistical significance was shown between the two groups. 4. Mothers in experimental group were more likely to have higher mean scores in mother and infant interaction during feeding than mothers in the control group. Statistical significance was shown between the two groups(t= 5.78, P=.001). In conclusion, the massage therapy in this study showed with regard to even though through there was no statistically significance in the weight gain and urine stress hormone concentration. there was Statistical significantly higher in the mother and infant interaction during feeding. Based on the result of this study, it is considered that the massage therapy should be applied clinical practice and home to help a developmental growth and interaction of Low Birth Weight infants and mothers during the period of recovery.

목 적 : 본 연구에서는 48시간 이상의 기계 환기요법이 필요한 중증 태변흡입증후군(meconium aspiration syndrome, MAS)의 임상적 특성과 시간의 경과에 따른, 또한 폐표면 활성제 투여 전후의 호흡 부전 정도와 방사선 영상 소견의 변화를 분석해보고자 하였다. 방 법 : 2004년 1월부터 2007년 7월까지 분당서울대학교병원 신생아중환자실에 중증 MAS로 입원하였던 12명의 환아를 대상으로 후향적인 분석을 하였다. 결 과 : PPHN의 발생은 긴 입원기간과 긴 총 기계 환기요법 적용기간에 독립적으로 영향을 미치는 인자였다. 폐표면 활성제는 RDS의 방사선 영상 소견이 있었던 경우에만 투여되었다. RDS의 방사선 영상 소견이 있었던 8명(75%)의 환아들에서는 그렇지 않았던 경우에 비해 고빈도진동환기기 적용기간이 유의하게 길었다. PPHN은 8명(75%)의 환아들에서 발생하였고 이들은 PPHN이 발생하지 않았던 환아들에 비해 기계 환기요법 기간이 유의하게 길었다. 폐표면 활성제를 투여 받은 환아들은 투여 후 12시간 이내에 모두 방사선 영상 소견의 호전을 보였으나 같은 기간 동안 호흡 부전 정도의 유의한 변화는 관찰되지 않았다. PPHN이 발생하지 않은 환아들에서는 폐표면 활성제를 투여한 후 12시간 이내에 유의한 호흡 부전 정도의 감소가 관찰되었으나 PPHN이 발생한 환아들에서는 그렇지 않았다. 결 론 : 중증 MAS의 임상경과는 PPHN의 발생여부에 따라 유의한 차이를 보였다. RDS에 합당한 방사선 영상 소견이 동반되었던 환아들에서의 폐표면 활성제의 투여는 방사선 영상 소견의 호전을 가져왔지만 이들의 임상경과에는 유의한 영향을 주지 못하였다.
