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.

Purpose: The purpose of this study was to identify the causes, symptoms, and complications of hypoproteinemia to prevent hypoproteinemia and provide appropriate treatment to children with atopic dermatitis. Methods: Children diagnosed with atopic dermatitis with hypoproteinemia and/or hypoalbuminemia were retrospectively reviewed. The patients' medical records, including family history, weight, symptoms, treatment, complications, and laboratory test results for allergies and skin cultures, were examined. Results: Twenty-six patients (24 boys) were enrolled. Seven cases had growth retardation; 7, keratoconjunctivitis; 6, aural discharges; 5, eczema herpeticum; 4, gastrointestinal tract symptoms; and 2, developmental delays. In 21 cases, topical steroids were not used. According to the blood test results, the median values of each parameter were elevated: total IgE, 1,864 U/mL; egg white-specific IgE, $76.5kU_A/L$; milk IgE, $20.5kU_A/L$; peanut IgE, $30kU_A/L$; eosinophil count, $5,810/{\mu}L$; eosinophil cationic protein, $93.45{\mu}g/L$; and platelet count, $666.5{\times}10^3/{\mu}L$. Serum albumin and total protein levels decreased to 2.7 g/dL and 4.25 g/dL, respectively. Regarding electrolyte abnormality, 10 patients had hyponatremia, and 12, hyperkalemia. Systemic antibiotics were used to treat all cases, and an antiviral agent was used in 12 patients. Electrolyte correction was performed in 8 patients. Conclusion: Hypoproteinemia accompanying atopic dermatitis is common in infants younger than 1 year and may occur because of topical steroid treatment continuously being declined or because of eczema herpeticum. It may be accompanied by growth retardation, keratoconjunctivitis, aural discharge, and eczema herpeticum and can be managed through skin care and topical steroid application without intravenous albumin infusion.

In the past decade there has been increasing concern about the atopic dermatitis (AD) associated with environmental diseases. AD has been increased in the last decade and known as one of the multifactoral diseases, which has the genetic background and environmental factors at the same time. The purposes of this study were to investigate the prevalence rate and etiologic risk factors of atopic dermatitis in preschool children in Changwon, which is a one of the Korean cities and has a large industrial complex. We reviewed and analyzed the statistical data, obtained from Korea National Health Insurance Corporation, related to prevalence rate by age and administrative district. A cross-sectional questionnaire survey, based on ISAAC (International Study of Allergy and Asthma in Childhood), was conducted on random samples of preschool children (5 to 8 years old) of large sized kindergartens in Changwon. The lifetime and last one years prevalence of AD in preschool children in Changwon was increased from 1998 to 2008. The prevalence rate of AD in the preschool children in Changwon city was 9.6%. The prevalence rate in boys was 9.7% and that in girls was 9.4%. The one year prevalence of AD was ranked as middle among other provincial cities in Korea in 2008. This study showed that the prevalence rate of the atopic disease in Changwon was 9% in 2008, which was increased especially compare to 2000. More active governmental approaches for control and prevention of atopic dermatitis for children are recommended. Further studies are needed for more accurate estimation of the prevalence of AD in Korea including different regional and age population.

Atopic dermatitis is one of the most common skin disease in children and a characteristic chronically recurrent form of dermatitis with a hereditary tendency, affecting infants and may extend to the childhood or th the adult age. Environmental factors, stress, and foodstuffs such as milk, egg may cause atopic dermatitis. Nc/Nga mice were used as an animal model for human atopic dermatitis. The divided by 4group such as normal group, BMAC group, FK506 group, MR group for this study raised in conventional conditions. To investigate effect of Chamomile German on atopic dermatitis in NC/Nga mice, the serum IgE and IgG1 level were measured while the severity degree of the skin lesion was examined by the naked eyes of two volunteers who were unaware of the treatment status. The results were the followings. 1. The score on the severity degree of skin dermatitis in FK 506 and MR group was lower than that in control group. 2. The serum IgE level in control group was higher 25% than that in normal group. 3. The serum level of IgE in FK506 and MR group compares to control group was decreased. 4. The serum IgG1 level was decreased more than 3.5 times in FK506 compared to control group while MR group had significantly less the serum IgG1 than control group. From the above results, treatment of Chamomile German oil had the effect on atopic dermatitis in NC/Nga mice. If scientific researches on aroma oil are performed in various way, aroma oil will be used to cure skin dermatitis as a alternative therapy in the future.

Purpose: Atopic dermatitis (AD) is a chronic inflammatory relapsing skin disorder. Vitamin D plays a pivotal role in the development of AD, and interleukin (IL) 31 is known to be related to pruritus in AD. The aim of our study was to determine whether 25-hydroxyvitamin D (25(OH)D) levels are related to IL-31 levels or to the severity of AD. Methods: We enrolled 91 children with AD and 32 control subjects without history or symptoms of allergic diseases. Blood was drawn to evaluate complete blood cell count, total eosinophil count (TEC), and total IgE, specific IgE to common allergens, 25(OH)D, and IL-31 levels. Serum 25(OH)D and IL-31 levels were measured using high-performance liquid chromatography and enzyme-linked immunosorbent assay, respectively. The scoring atopic dermatitis (SCORAD) index was used to evaluate the severity of AD. Results: The mean 25(OH)D level was significantly lower in the AD group than in the control group; 25(OH)D decreased greatly in the moderate and severe AD groups compared with the mild AD group. Children with atopic sensitization showed significantly lower 25(OH)D levels than nonatopic children. However, serum IL-31 levels were not related to AD group, SCORAD index, or 25(OH)D levels. The SCORAD index was inversely correlated with serum 25(OH)D level and positively correlated with TECs and total IgE levels. Children with moderate and severe AD had significantly higher TECs than children with mild AD. Conclusion: Vitamin D is related to the severity of AD independently of IL-31.

The prevalence of atopic dermatitis (AD) has increased recently all over the world. Several studies worldwide reported growth retardation associated with AD, but few studies were reported in Korea. Therefore, the objective of this study was to identity the differences in growth and nutrient intakes between Korean children with and without AD. The participants were 71 AD children and age, gender-matched 81 control children aged 10 to 36 months. Demographic information was gathered by questionnaires. Height and weight were measured at clinic and health centers. Height and weight for age, and weight for height were converted as deviation in Z scores using World Health Organization Standard. A 24 hour dietary recall method was performed to estimate nutrient intakes. A higher percentage of AD children had insufficient energy and intakes of calcium, phosphorus, iron, zinc and vitamin B2, defined as intakes lower than 75% of the Dietary Reference Intakes for Korean, compared to the control group (P < 0.001, P < 0.001, P = 0.003, P = 0.001, P = 0.014, P = 0.001, respectively). The percentages of children with height and weight for age Z score below than-1 (stunted) were significantly higher in the AD group (P < 0.001 and P < 0.001, respectively). Multiple food restriction, defined as ${\geq}$ 3 food elimination, was associated with insufficient energy and intakes of calcium, phosphorus, iron, zinc, vitamins A and B2. In conclusion, children with AD need regular nutrient assessment and education about alternative food choices to avoid r food elimination in order to prevent growth retardation or inadequate nutrient intakes. Further longitudinal studies for growth and nutrient intakes should be performed to understand the patterns of growth in children with AD.

Objectives : This study aimed to investigate the awareness improvement of atopic dermatitis(AD) for AD children's parents and to evaluate the mental health condition of AD children and QoL of their parents. Methods : We conducted elementary school visit education(the first education) and recruited children and parents who wanted to participate the hospital visit education(the Second education). In the first education, we lectured about AD, performed survey about QoL and awareness about AD and obtained 48 valid results. In the second education, we performed an education for AD again, skin condition evaluation, mental health analysis survey and obtained 29 valid results. We compared the AD and non-AD groups of each education in the first and second education. We assessed atopic awareness, FDLQI, DFI, CDI, BAI, and KISE scores by gender, age, duration of disease, onset, and severity of AD. Results : Despite children with AD, the survey showed their parents lacked knowledge about AD. However, they acquired the necessary knowledge in AD education. There was a significant difference in the total score of Atopic awareness between the AD group in the first education and the AD group in the second education. (p=0.042) In addition, the CDI and BAI scores of all patients were divided by the duration of disease, and it was estimated that depression and anxiety disorders may be aggravated by longer term illness. Conclusions and Discussions : This study confirmed duration of AD affects AD children's mental health, and verified positive changes in atopic awareness after AD education.

Atopic dermatitis (AD) has become a serious epidemic in Korean children. We aimed to investigate the association between vitamin C, E and other nutrients, and serum total IgE/specific IgE levels in children with AD. A total of 119 children (0-24 mo) diagnosed with AD were recruited for this cross-sectional study from a medical center in Seoul. A 24 h recall was used to assess dietary intakes. Serum total and six food-allergen specific IgE levels were measured by CAP-FEIA. Serum vitamin E was also measured but only in 25 out of the total 119 participants. Multiple linear regression analysis was performed to estimate the coefficients between serum IgE levels and dietary intake as well as serum vitamin E. Serum vitamin E levels showed a significantly inverse association with serum total IgE and all specific IgE levels (P < 0.05). Fat intake was inversely related with specific-IgEs for egg whites, milk, buck wheat, soy, and peanuts (P < 0.05). Positive associations were found between carbohydrate (CHO) intake and total IgE and specific IgEs to egg whites, milk, soy, and peanuts (P < 0.05). Vitamin C, E and n-3/n-6 fatty acids were not related with serum total IgE and specific IgE levels except for the association between buck wheat and vitamin E. In addition, there were no significant differences between males and females in dietary intake and serum IgE levels by student's t-test. Although dietary vitamin E showed no association with serum IgE levels, serum vitamin E drew a significant inverse relationship with serum IgE levels. The evidence seems to suggest that vitamin E may possibly lower total and specific-IgEs in children with AD, and that it is important to maintain a relatively high serum vitamin E level in children with AD.

Background: Allergic inflammation was induced by activated Th2 lymphocytes, leading to IgE production and eosinophil activation. A Th2 disproportion was shown in atopic children soon after birth. During specific allergen stimulation, an increase of Th2 cells was observed in most cases. In this study, we prepared new screening "whole blood" system for searching the anti-atopic materials. Cytokine production and IgE secretion from whole blood system were assessed and we confirmed the results by using animal system. Methods: Pathological features in NC/Nga mice are similar to those observed in human atopic dermatitis. Whole blood from NC/Nga mouse was stimulated by using TNCB (Th2 activator) or candidate materials of anti-atopic dermatitis, and the production of cytokines (IL-4, IL-12, and IFN-${\gamma}$) were measured by ELISA. In order to confirm the results of whole blood system, in vivo test was done by using NC/Nga mice. Results: In whole blood system, LPS and extracts of green tea, hardy orange and onion induced the production of IL-12 and IFN-${\gamma}$ while they reduced the production of IL-4. Also, LPS and extracts of onion reduced IgE production. Though atopic dermatitis was observed from a mouse stimulated with TNCB, it was not when a mouse was co-stimulated in LPS or extracts of onion. The results are same as those observed in whole blood system. Conclusion: Whole blood system was simple and speedy methods for searching a materials compared with the conventional high-cost animal system. And the results using whole blood system was proved to be reliable in our experiments for screening anti-atopic material. We expect that the system can be applied to other experiments for searching similar materials.

Purpose: The purpose of this study was to investigate factors affecting childhood asthma and atopic dermatitis. Methods: For this study, data for 1,170 children (1-11 years) from the Fifth Korean National Health and Nutrition Examination Survey (KNHANES V-2, 2011) were analyzed. First correlation matrices were computed to test the normality of every data set and then to be in accordance with the real demographic composition, data were added weight before being analyzed. Results: The child with asthma of a three generation family (OR=3.91, 95% CI [1.33, 11.45], p=.013) compared with a two generation family showed higher asthma development, and maternal asthma (OR=9.71, 95% CI [2.66, 35.40], p=.001) showed higher asthma development in child. The only factor affecting atopic dermatitis was parental perceptions of child health: poor (OR=3.40, 95% CI [1.29, 8.98], p=.014). Conclusion: These results suggest that childhood asthma and atopic dermatitis are both affected by parental perceptions of child health. Accordingly, management and support programs for children who have asthma and/or atopic dermatitis and their families should be comprehensive and also give attention to any other health problems because health perception represents quality of life.
