The fetus is greatly influenced by mother's health condition and her environment. So in our traditional society, the prenatal care is regarded as important for generations to birth of sound baby in mind and boy. Purpose : We aimed to reserch what kind of mother's conditions can be more influential to infant allergic disease among traditional prenatal care. Method : We investigated 91 patients who answered by a questionnaire at Dept. of Pediatrics, Oriental Hospital of Dae-jeon University. We divided patients into two groups, A(normal group;43) and B(allergic disease group;48) and analyzed those. Results : The pregnant women in the group B, generally have worse health conditions and are under the stress mentally and cannot get enough nutrition because of morning sickness and digestive trouble, but take more pungent and powdered food than the group A. Specially, the result is significant in anger and worry among other mental stresses and in digestive trouble and threatened abortion among other health conditions(according to order: p<0.001, p<0.05, p<0.01, p<0.001). We can see that pregnant woman's peaceful mentality and enough nutrition intake are most important to birth of sound baby in mind and also we can see that pregnant woman's regimen has influence on not only infant disease but also character and the infant allergic diseases are related to inheritable factor.

Atopic sensitization is a complex phenomenon that changes dynamically with age throughout childhood; its prevalence increases with age in young children. Additionally, with increasing age, the prevalence of sensitization to inhalant allergens and the prevalence of polysensitization to allergens increase. It is also well established that the development of atopic sensitization is the result of a complex interplay of genetic and environmental factors. However, there is considerable heterogeneity in the literature in terms of the effect of different environmental exposures in young children on the subsequent risk of atopic sensitization and allergic diseases. Previous studies on the relationship, in early life, between pet ownership, sex, exposure to secondhand smoke, exposure to traffic-related air pollution components, and atopic sensitization have yielded different results. Recent studies have highlighted the importance of gene-environment interactions, especially during early childhood, on the risk of subsequent atopic sensitization and allergic diseases. Therefore, pediatricians should consider the genetic and environmental determinants of atopic sensitization in infants and young children when diagnosing and treating patients with allergic diseases. Determining ways in which early exposure to these risk factors in young children may be reduced could be beneficial in preventing the likelihood of developing atopic sensitization.

Purpose: Previous studies suggest that the concentration of 25-hydroxyvitamin D [25(OH)D] in cord blood may show an inverse association with respiratory tract infections (RTI) during childhood. The aim of the present study was to examine the influence of 25(OH)D concentrations in cord blood on infant RTI in a Korean birth cohort. Methods: The levels of 25(OH)D in cord blood obtained from 525 Korean newborns in the prospective COhort for Childhood Origin of Asthma and allergic diseases were examined. The primary outcome variable of interest was the prevalence of RTI at 6-month follow-up, as diagnosed by pediatricians and pediatric allergy and pulmonology specialists. RTI included acute nasopharyngitis, rhinosinusitis, otitis media, croup, tracheobronchitis, bronchiolitis, and pneumonia. Results: The median concentration of 25(OH)D in cord blood was 32.0 nmol/L (interquartile range, 21.4 to 53.2). One hundred and eighty neonates (34.3%) showed 25(OH)D concentrations less than 25.0 nmol/L, 292 (55.6%) showed 25(OH)D concentrations of 25.0-74.9 nmol/L, and 53 (10.1%) showed concentrations of ${\geq}75.0$ nmol/L. Adjusting for the season of birth, multivitamin intake during pregnancy, and exposure to passive smoking during pregnancy, 25(OH)D concentrations showed an inverse association with the risk of acquiring acute nasopharyngitis by 6 months of age (P for trend=0.0004). Conclusion: The results show that 89.9% of healthy newborns in Korea are born with vitamin D insufficiency or deficiency (55.6% and 34.3%, respectively). Cord blood vitamin D insufficiency or deficiency in healthy neonates is associated with an increased risk of acute nasopharyngitis by 6 months of age. More time spent outdoors and more intensified vitamin D supplementation for pregnant women may be needed to prevent the onset of acute nasopharyngitis in infants.

We aimed to investigate associations of dietary diversity (DD) with gut microbial diversity and the development of hen's egg allergy (HEA) in infants. We enrolled 68 infants in a high-risk group and 32 infants in a control group based on a family history of allergic diseases. All infants were followed from birth until 12 months of age. We collected infant feeding data, and DD was defined using 3 measures: the World Health Organization definition of minimum DD, food group diversity, and food allergen diversity. Gut microbiome profiles and expression of cytokines were evaluated by bacterial 16S rRNA sequencing and real-time reverse transcriptase-polymerase chain reaction. High DD scores at 3 and 4 months were associated with a lower risk of developing HEA in the high-risk group, but not in the control group. In the high-risk group, high DD scores at 3, 4, and 5 months of age were associated with an increase in Chao1 index at 6 months. We found that the gene expression of IL-4, IL-5, IL-6, and IL-8 were higher among infants who had lower DD scores compared to those who had higher DD scores in high-risk infants. Additionally, high-risk infants with a higher FAD score at 5 months of age showed a reduced gene expression of IL-13. Increasing DD within 6 months of life may increase gut microbial diversity, and thus reduce the development of HEA in infants with a family history of allergic diseases.

In modern society, we are living indoor at 80 - 90 % or more of the day, therefore most people are exposed to unconscious indoor air pollutants by various causes. When mother and infant, whose level of immunity are weak, are exposed to polluted indoor air, respiratory diseases and atopy can occur by the growth of bacteria. Therefore, appropriate indoor air quality management is important especially at nursery, elementary school and postpartum clinic etc. In this study, we compared the characteristics of the indoor air qualities of primary school facilities and infant facilities. In this study, seasonal effects were investigated. Also the effects of individual activity area were studied for indoor air quality. During summer season(May-August), the air qualities of each 16 elementary school and nursery school were investigated. During winter season(October-december), the air qualities of each 10 elementary school and nursery school were investigated. As a result, during winter season in 10 of 16 nursery school, $CO_2$ concentration exceeded regulation level of 1000 ppm. This resulted from the operation of heating system and poor ventilation. Also the air quality of all parameters during winter season were worse than during summer, maybe due to poor ventilation. Except HCHO, the concentrations of other parameters were higher in nursery school. This seems to result from relatively low individual activity area of nursery school than elementary school. From this research, more strong regulation for ventilation and installation of air purifier should be implemented.

Previous infant feeding guidelines recommended a delayed introduction of solids to beyond 6 months of age to prevent atopic diseases. However, scientific evidence supporting a delayed introduction of solids for prevention of atopic diseases is scarce and inconsistent. Current evidence does not support a major role for maternal dietary restrictions during pregnancy or lactation in the prevention of atopic disease. In studies of infants at high risk of developing atopic disease, there is evidence that exclusive breastfeeding for at least 4 months compared with feeding intact cow milk protein decreases the incidence of atopic dermatitis, cow milk allergy, and wheezing in early childhood. For infants at high risk of developing atopic disease who are not breastfed exclusively for 4 to 6 months, there is modest evidence that atopic dermatitis may be delayed or prevented by the use of extensively or partially hydrolyzed formulas, compared with cow milk formula, in early childhood. There is no convincing evidence that a delayed introduction of solid foods beyond 4 to 6 months of age prevents the development of atopic disease. For infants after 4 to 6 months of age, there are insufficient data to support a protective effect of any dietary intervention for the development of atopic disease.

Some pediatric patients who can not eat orally depend on enteral tube feedings, and some patients require more nutrients and calories to achieve the catch-up growth. If a patient is counting on the parenteral nutrition, early initiation of enteral feeding, orally or enterally, is a very good for the intestinal mucosal maturity and motility. There are numerous kinds of formulas and supplements for the enteral feeding for neonates, infants, and children. Depending on the intestinal symptoms, allergic symptoms, requirement of special nutrients, we can choose regular infant formula (milk-based, soy-based), protein hydrolysate formula, amino acid hydrolysate formula, elemental formula. Proper use of these formulas would help for the pediatric patients to recover from their diseases, to facilitate the intestinal mucosal maturity and to achieve their goal of growth.

목 적 : 알레르기 질환의 증가가 Th1/Th2 세포 면역의 불균형에 의한다는 것은 널리 받아들여지고 있다. 이에 본 연구에서는 미숙아의 제대혈에서 Th2 세포의 다른 사이토카인 분비를 증가시키는 IL-4, Th1 세포 분화를 억제하는 IL-10 및 강한 Th2 세포 억제 작용을 하는 IL-12를 측정하여 그 상관관계를 알아보고자 하였다. 방 법 : 2003년 1월부터 2005년 7월까지 이화여자대학교 부속 목동병원에서 출생한 34주 미만의 미숙아 중 보호자 동의하에 제대혈 검사가 가능하였던 46명을 대상으로 하여 의무기록을 통해 대상아의 천명의 발현 여부, 천식의 발생 여부에 대한 자료를 얻었다. 제대혈은 출생 시 채취하여, 즉시 혈청을 원심 분리하여 $-70^{\circ}C$ 냉동고에 보관하였다가 ELISA법을 이용하여 IL-4, IL-10 및 IL-12를 측정하였다. 결 과 : 관찰 기간은 12개월에서 36개월로 평균 16.0개월${\pm}13.2$일 이었고, 연구 기간 중 천명군은 18명이었으며, 비천명군과 비교하였을 때 IL-12가 유의하게 낮았다($366.60{\pm}140.40pg/mL$ vs. $435.10{\pm}91.20pg/mL$, P=0.009). IL-10은 천명군이 비천명군에 비해 높은 수치를 보였으나($2.60{\pm}5.11pg/mL$ vs $0.40{\pm}0.39pg/mL$) 통계적 의의는 없었다. IL-4는 차이가 없었다. 천식군은 4명으로 이들의 IL-12은 $282.60{\pm}128.88pg/mL$, 비천식 천명군 $392.40{\pm}138.06pg/mL$, 비천명군 $435.10{\pm}91.20pg/mL$로 세 군 사이에 유의한 차이가 있었다(P=0.045). 결 론 : 천명 및 천식이 발생한 영아에서 제대혈 IL-12 수치가 낮아 출생 시부터 면역학적인 불균형이 있었음을 예상할 수 있으며, 제대혈의 IL-12 수치로 생후 알레르기 호흡기 질환 발생을 예측하여 출생 시부터 보다 적극적인 알레르기 질환의 예방에 기여할 수 있을 것으로 생각된다.
