Purpose: In this study, we aimed to investigate the prevalence of year-round respiratory viral infection in children with lower respiratory tract infection (LRTI) and the relationship between respiratory viral infection and allergen sensitization in exacerbating asthma. Methods: We investigated the sources for acute LRTIs in children admitted to our hospital from May 2010 to April 2011. The 6 most common respiratory viruses were isolated from nasopharyngeal aspirate using multiplex reverse transcription-polymerase chain reaction in 309 children; respiratory syncytial virus (RSV), adenovirus (AV), parainfluenza virus (PIV), influenza virus (IFV), human metapneumovirus (hMPV), rhinovirus (RV). Atopic sensitization was defined if more than 1 serum specific Immunoglobulin E level measured using UniCAP (Pharmacia) was over 0.35 IU/mL. Results: RSV was the most common pathogen of bronchiolitis in hospitalized children through the year. RV or IFV infection was more prevalent in asthma exacerbations compared to other LRTIs. AV and hMPV were more likely to cause pneumonia. RV and IFV were associated with asthma exacerbations in children with atopic sensitization, but not in nonatopic children. Conclusion: RV and IFV are associated with hospitalization for asthma exacerbation in children with atopic sensitization.

Allergic diseases, including atopic dermatitis, asthma, allergic rhinitis, and food allergies, could be caused by dysbiosis that results in an immune system imbalance. The incidence of allergic diseases has been increasing and they are now one of the most common diseases throughout the world. Recently, probiotics have been suggested as an alternative intervention for the prevention and treatment of allergic diseases. Probiotics are endogenous microflora with functional effects within hosts. They have various clinical and immunological capacities and have recently been considered as a supplement for the treatment and prevention of allergic diseases. Probiotic bacteria modulate immune cells such as Th1, Th2, and regulatory T cells that are correlated with protection against atopic dermatitis, however, safety concerns for the use of probiotics have been raised. Therefore, further research is needed to clarify the efficacy and safety of probiotics in the treatment of allergic diseases.

Objectives: We evaluated the effects of an allergy control program on children with atopic dermatitis (AD) in five schools located within Gyeonggi-do. Methods: Based on the results of the 12-month prevalence of AD symptoms from an International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire of all students (n=2109; 1040 boys, 1069 girls) at five randomly selected schools, 227 students with AD symptoms were screened. Finally, 188 students with greater than 1 on SCORAD (SCORing Atopic Dermatitis) determined by a physician were selected. The allergy control program includes education related to allergic diseases, skin prick tests, and SCORAD evaluation, as well as keeping a daily journal to check the usage of moisturizer at least once a day. To determine the effectiveness of the allergy control program, SCORAD evaluation was performed again six weeks later. Results: The most common symptom for 12-month prevalence was rhinorrhea (33.9%), followed by atopic skin lesions (14.8%) and wheezing (4.0%). The 12-month prevalences of the three allergic diseases were higher for boys than for girls, and a significant difference was found for allergic rhinitis (P<0.001). The mean SCORAD index decreased significantly from 26.1 to 17.5 after the completion of the six-week control program (P<0.01). In particular, these differences were more pronounced for the group which used the daily journal (P<0.001). Conclusions: Our findings indicate that the allergy control program including usage of a daily journal as well as regular monitoring could be a promising tool for preventing and alleviating the symptoms of allergic diseases.

The prevalence of allergic disorders has dramatically increased over the past decade, particularly in developed countries. Apart from gastrointestinal disorders, neoplasia, genital and dermatological diseases etc., dysregulation of gut microbiota (dysbiosis) has also been found to be associated with increased risk of allergies. Probiotics are increasingly being employed to correct dysbiosis and, in turn, to modulate allergic diseases. However, several factors like strain variations and effector metabolites or component of them in a bacterial species can affect the efficacy of those as probiotics. On the other hand, host variations like geographical locations, food habits etc. could also affect the expected results from probiotic usage. Thus, there is a glaring deficiency in our approach to establish probiotics as an irrefutable treatment avenue for suitable disorders. In this review, we explicate on the reported probiotics and their effects on certain allergic diseases like atopic dermatitis, food allergy and asthma to establish their utility. We propose possible measures like elucidation of effector molecules and functional mechanisms of probiotics towards establishing probiotics for therapeutic use. Certain probiotics studies have led to very alarming outcomes which could have been precluded, had effective guidelines been in place. Thus, we also propose ways to secure the safety of probiotics. Overall, our efforts tend to propose necessary discovery and quality assurance guidelines for developing probiotics as potential immunomodulatory 'Pharmabiotics.'

Objectives: We investigated the effects of air pollution on allergic diseases (allergic rhinitis, asthma, atopic dermatitis) in metropolitan cities in Korea, adjusting for meteorological factors. Methods: Data on daily hospital visits and hospital admissions for 2003-2010 was obtained from the National Health Insurance Cooperation. Meteorological data was obtained from the Korea Meteorological Administration. We then calculated daily mean temperature, daily mean humidity, daily mean air pressure at sea level, and diurnal temperature range. We used data on air pollution provided by the National Institute of Environmental Research. Maximum daily eight-hour average ozone concentrations and the daily mean $PM_{10}$ were used. We estimated excess risk and 95% confidence interval for the increasing interquatile range (IQR) of each air pollutant using Generalized Additive Models (GAM) that appropriate for time series analysis. Results: In this study, we observed an association between ozone and hospital visits for allergic rhinitis, asthma, and atopic dermatitis in all metropolitan cities, adjusting for temperature, humidity, air pressure at sea level, diurnal temperature range, and day of the week. Ozone was associated with hospital visits for allergic rhinitis, asthma, and atopic dermatitis across all metropolitan cities. However $PM_{10}$ was associated with allergic-related diseases in only select cities. Also, ozone and $PM_{10}$ were associated with hospital admission for asthma in all cities except Gwangju. Hospitalization for the other diseases failed to show consistent association with air pollutants. Conclusion: In the findings of this study, there was a significant association between air pollutants and allergic-related diseases. More detailed research subdivided age group or conducting meta-analyses combining data of all cities is required.
