Abstract
Purpose This study was meant to analyze immune infiltration and construct a ceRNA network to explore the new therapeutic targets for atopic dermatitis (AD) through bioinformatics way. Patients and Methods We downloaded the AD patients’ RNA expression profile datasets (GSE63741, GSE124700) from the Gene Expression Omnibus (GEO) database, which were analyzed through the GEO2R. We explored the hub genes by the enrichment analysis and the protein–protein interaction (PPI) analysis. Moreover, we estimated immune cell types and their proportions by ImmucellAI. GSE121212 dataset validation was performed to verify the robustness of the hub genes. Then, a ceRNA network was constructed by the miRWalk, miRNet, miRDB, DIANA, TargetScan, and starbase database. Finally, gene expression analysis was performed by using RT-qPCR. Results In total, we detected 22 differentially expressed genes (DEGs), which contained 8 downregulated genes and 14 upregulated genes. There were 5 hub genes confirmed as key genes through PPI network analysis and the ROC curves. KEGG pathway analysis revealed that they were significantly enriched in the IL-17 signaling pathway and GO analysis showed mainly in the immune cell chemotaxis. The immune infiltration profiles were different between normal controls and AD, and each of the key genes (S100A7, S100A8, S100A9, and LCE3D) was significantly correlated with the main infiltration cell of AD. A lncRNA–miRNA–mRNA ceRNA network containing the key genes was constructed, and NEAT1 and XIST, the core of ceRNA network, were significantly overexpressing verified by RT-qPCR in AD patients. Conclusion Altogether, the key genes and their ceRNA network provided a novel perspective to the immunomodulation of AD, which may be potential and new therapeutic targets for AD.

Abstract
BACKGROUND Atopic dermatitis (AD) is one of the most common allergic diseases in children. The aim of the study was to evaluate the ultrasound picture of lesional and non-lesional skin in children with AD. MATERIALS AND METHODS The study included a group of children with AD and a control group. Inclusion criteria were as follows: age 0-8 years and clinical diagnosis of AD. An ultrasound scanner with a 75 MHz transducer probe was used to produce B-mode skin images in lesions and non-lesional skin. The thickness and the echogenicity of epidermis, dermis, and subepidermal low-echogenic band (SLEB) were measured, and the ratio coefficient per body site was calculated. RESULTS Ultrasonography of non-lesional skin in children with AD showed uneven epidermis contour, a tendency to increased epidermis and decreased dermis thickness, and the SLEB was observed in 77% of cases. In lesions, there was an increased thickness and a decreased echogenicity of epidermis and dermis, and epidermis had irregular contours in most cases. The SLEB was in all lesions, showing greater thickness and lower echogenicity compared with non-lesional skin. CONCLUSION HF-USG of the skin allows visualizing the epidermal barrier disruption and inflammation in dermis in children with AD on the entire surface of the skin.

Abstract
Consistent evidence has been found on the relationship between food allergy (FA) and atopic dermatitis (AD) in some children. Food sensitization can be often found in these patients. Allergy should be confirmed, though, with a food challenge test (FC) before advising a restrictive diet which could be harmful for the patient. Younger children with AD frequently show sensitization to egg, milk or peanut, while older ones and adults are more often sensitized to environmental allergens such as house dust mites, moulds, animal dander or pollens. It is well known that a barrier disturbance plays a main role in the development of sensitization and allergy. Therefore, due to the early appearance of AD, preventive newborn skincare with emollients and early introduction of food appear to be very important to determine food tolerance.

Abstract
BACKGROUND Atopic eczema and food allergy most commonly occur in the early childhood. However, the relationships between eczema onset and their relevance to the occurrence of atopic diseases relating to allergen sensitization remain unclear. METHODS We investigated 186 children who were followed up regularly at the clinic for 4 years in a birth cohort study. The children were classified into three groups: early-onset eczema (<2 years old, n = 55), late-onset eczema (≥2 years old, n = 40), and never eczema groups (n = 91). The associations between the different onsets of eczema and total immunoglobulin E levels, absolute eosinophil count, sensitization to food and inhalant allergens, and allergic outcomes were assessed. RESULTS A significantly higher prevalence of sensitization to food, especially milk was observed in children with early-onset eczema compared with those without eczema at age 1, 1.5, 2, 3, and 4 years. Furthermore, a significantly higher number of eosinophils was detected in children with early or late-onset eczema at the age of 1.5 years. Both the early- and late-onset eczema were significantly associated with a higher prevalence of allergic rhinitis at age 2, 3, and 4 years, and asthma at age 2. Moreover, the early-onset eczema group showed a significantly increased risk of allergic rhinitis (P = 0.010) and asthma (P = 0.032) at age 4. CONCLUSION The children with early-onset eczema (<2 years old) appear to be associated with an increased prevalence of milk sensitization and risk of rhinitis and asthma in early childhood.

Abstract
BACKGROUND Although recent studies suggest that eczema in early childhood is important in the development of food allergy, the importance of the timing of eczema onset has not been fully clarified. OBJECTIVE This study aim to identify an association between the timing of eczema onset and development of food allergy in a prospective birth cohort study. METHODS Data were obtained from the Tokyo Children's Health, Illness and Development (T-CHILD) study, which is a hospital-based birth cohort study currently in progress in Japan. A total of 1550 children were born to the recruited women. Outcome data for children were collected from questionnaires completed at 6 months, 1 and 3 years of age. Association between the timing of eczema onset and development of food allergy was estimated by logistic regression analyses. All analysis were performed using SPSS software with a two-sided 5% significance level. RESULTS Eczema in the first year of life was a significant risk factor in multivariate analysis (aOR 3.90, 95% CI 2.34-6.52, p<0.001). In each age (by month) stratum, infants with onset of eczema within the first 1-2 months after birth had the highest risk of food allergy at 3 years of age (aOR 6.61, 95% CI 3.27-13.34, p<0.001). CONCLUSION Infants with early eczema onset (especially within the first 1-4 months after birth) were found to have an increased risk of developing food allergy at 3 years of age. Our findings may contribute to a better understanding of the timing of eczema onset as a potentially modifiable risk factor and to defining those who may need to be on guard for food allergy.

Abstract
Atopic dermatitis (AD) is a common, recurrent, chronic inflammatory skin disease that is a cause of considerable economic and social burden. Its prevalence varies substantially among different countries with an incidence rate proclaimed to reach up to 20% of children in developed countries and continues to escalate in developing nations. This increased rate of incidence has changed the focus of research on AD toward epidemiology, prevention, and treatment. The effects of probiotics in the prevention and treatment of AD remain elusive. However, evidence from different research groups show that probiotics could have positive effect on AD treatment, if any, that depend on multiple factors, such as specific probiotic strains, time of administration (onset time), duration of exposure, and dosage. However, till date we still lack strong evidence to advocate the use of probiotics in the treatment of AD, and questions remain to be answered considering its clinical use in future. Based on updated information, the processes that facilitate the development of AD and the topic of the administration of probiotics are addressed in this review.

Abstract
From April 2011 to April 2012, we conducted a cross-sectional study in Shanghai, China. A total of 13,335 modified ISAAC questionnaires (response rate: 85.3%) were returned by parents or guardians for 4-6 year-old children. Six dampness-related indicators (visible mold spots, visible damp stains, damp bed clothing, water damage, window pane condensation, and moldy odor) were used to evaluate home dampness-related exposures. In the present study, we applied logistic regression model to reveal associations, dose-response relationships, and statistical interaction effects of these dampness-related exposures, with childhood eczema, during lifetime since birth (ever) and in the last 12 months before the questionnaire. The dampness-related indicators were frequently reported in the perinatal and current residences. Prevalences of eczema ever and in the last 12 months were 22.9% and 13.2%, respectively. The dampness-related indicators were robustly associated and dose-response related with increased risk of eczema ever and in the last 12 months in the logistic regression analyses, with adjusted for potential confounders. Specifically, in the perinatal residence, visible mold spots or damp stains could increase 46% (OR, 95% CI: 1.46, 1.29-1.66) odds of childhood eczema (ever); in the current residence, visible mold spots and visible damp stains could increase 34% (1.34, 1.14-1.58) and 38% (1.38, 1.22-1.56) odds of childhood eczema (ever), respectively. Associations were not appreciably different between boys and girls, nor were they different between children with and without parental history of atopy. In conclusion, perinatal and current dampness-related exposures in the residence perhaps are risk factors for childhood eczema.

Abstract
The prevalence of allergic diseases including atopic dermatitis, asthma, allergic rhinitis (AR) and food allergy is increasing worldwide and they cause a big economic and social burden. Understanding of reasons that contribute to the etiology of allergic diseases as well as new treatment approaches are very important for the follow-up and prevention of these diseases. In recent years, probiotics seem to be promising for allergic diseases. The effect of probiotics in the prevention and treatment of eczema is more extensively studied, but little is known about the association of the microbial flora of the host and allergic airway diseases and the efficacy of probiotics in decreasing the symptoms of patients with asthma and rhinitis. Hitherto, there is no strong evidence for use of probiotics in the treatment of eczema; however, administration of probiotics in breastfeeding mothers in the prenatal period and infants in the postnatal period can be accepted as a safe and helpful option in the prevention of eczema. In contrast, there is not yet reliable evidence or recommendations on use of probiotics for the prevention or treatment of asthma, AR, food allergy, and anaphylaxis currently. More standardized studies should be performed with different strains of probiotics to evaluate the protective and therapeutic effects of probiotics on other allergic diseases as well as eczema. In this review, the relationship between allergy and probiotics is handled in the light of current literature.

Abstract
BACKGROUND Thymic stromal lymphopoietin (TSLP) polymorphisms influence atopy risk. TSLP might constitute a key interface between the environment and the allergic immune response. However, whether the effects of TSLP polymorphisms on atopic dermatitis (AD) are modified by allergic sensitization is not clear. OBJECTIVE To evaluate the joint effect of allergic sensitization and TSLP polymorphisms on AD and to test whether TSLP polymorphisms increase the risk of asthma in children with AD. METHODS A total of 1,520 kindergarten children (375 with AD and 1,145 controls) selected from the Childhood Environment and Allergic Diseases Study cohort in 2010 were enrolled. Information about allergic diseases and environmental exposures was collected by questionnaire. Skin prick tests were performed to measure allergic sensitization. TSLP polymorphisms were genotyped by TaqMan assay. Logistic regressions were conducted to estimate the association among TSLP polymorphisms, allergic sensitization, and AD. For replication, a subsample of the British Isle of Wight birth cohort was used. RESULTS The TSLP rs2289278 CC genotype increased the risk of AD (odds ratio 1.90, 95% confidence interval 1.12-3.22). In children sensitized to certain allergens, a genetic predisposition (rs2289278 genotype CC) significantly increased the risk of AD. These findings were replicated in the British subsample using rs2289276 genotypes TT and TC, which are in linkage disequilibrium with rs2289278. In subjects with AD, the rs2289278 C allele also significantly increased the risk of developing asthma (odds ratio 8.31, 95% confidence interval 1.08-64.13). CONCLUSION The association of rs2289278 with AD was stronger in children with allergic sensitization than in children without atopy. TSLP polymorphisms also increased the risk of asthma in children with AD.

Abstract
Pediatric eczema is a common disease which causes economic and social burden. Its incidence differs among the societies, with an incidence reported to reach up to 20% in developed countries. Eczema is the first allergic disease seen in the childhood, and it is recognized as a precursor for the development of atopic diseases such as asthma, allergic rhinitis, and food allergy in the forthcoming years of children. Increased incidence of eczema in recent years has led to new research in epidemiology, prevention, and intervention of this disease. It is no doubt important to treat itching, rash, and excoriation of the skin; however, treatment of pediatric eczema should not be considered only as a treatment of skin lesions. Considering skin treatment as the tip of the iceberg, proper management of the allergic processes can be accepted as the rest of the iceberg. The role of probiotics in the prevention of atopic eczema is yet to be clarified. Evidence presented by existing studies suggesting that probiotics may prevent pediatric eczema is not strong enough. A positive effect, if any, may be related with onset time, dose, duration, and use of specific probiotics. To date, there is no strong evidence for use of probiotics in the treatment of eczema; however, administration of probiotics in breast-feeding mothers in the prenatal period and in infants in the postnatal period can be accepted as a safe and helpful option in the prevention of eczema. Nevertheless, there are still questions to be answered in the future about probiotic administration for eczema. Clinical use of probiotics will gradually become more widespread when these questions are answered. Based on current information, the administration of probiotics for pediatric eczema topic is addressed in this review.

Abstract
BACKGROUND Cow's milk allergy (CMA) is the most common food allergy in infancy. Food allergy is generally triggered through ingestion, but can also be triggered through skin contact. We investigated the incidence and the clinical significance of cow's milk protein (CMP)-induced contact urticaria in individuals with CMA with and without atopic dermatitis (AD). METHODS A total of 157 children of whom 133 were diagnosed with CMA were participated. The study was based on observational data gathered in the course of patient care, including a skin prick test and a 'finger test', in which cow's milk is applied on the cheek by a physician's finger to detect contact urticaria. RESULTS Eighty nine of 133 patients (66.9%) had IgE-mediated CMA. Forty of these 89 (44.9%) tested positive in the finger test. Family atopy was higher in those with positive contact urticaria [21/40 (52.5%) vs. 14/49 (28.5%), p = 0.029]. Patients with positive vs. negative CMP contact urticaria had higher incidence of multiple food allergies [20 of 40 (50%) vs. 7/49 (14.3%), p < 0.004]. IgE-mediated CMA patients with AD had statistically higher CMP allergic contact urticaria compared to patients without AD [71% (15/21) vs. 37% (25/68), p = 0.0064]. Children with non-IgE milk allergy and healthy control group did not have contact urticaria to CMP. CONCLUSION CMP contact urticaria exists only in patients with IgE-mediated CMA. A 'finger test' to CMP should be part of the evaluation of CMA patients, and positivity suggests the potential for multiple food allergies, especially to sesame and egg.
