Community-acquired pneumonia is the leading cause of pediatric morbidity and mortality. However, there is a lack of data on the epidemiology of pneumonia in Korean children. In this review, we aimed to summarize pneumonia studies in Korea and suggest diagnostic methods and treatment for Korean children who were referred based on the foreign guidelines for pediatric community-acquired pneumonia. A Korean guideline for pediatric pneumonia in tune with domestic circumstances is needed.

Atopic dermatitis is the most common chronic inflammatory skin disease in children. It usually develops in infancy and early childhood and is an entry point of ‘atopic march’, which may progress to other allergic diseases, including allergic rhinitis and asthma. Although there is no disagreement on the importance of early treatment of atopic dermatitis, it is difficult to treat children with moderate to severe atopic dermatitis due to concerns about treatment-related side effects and age restrictions for effective drugs in real world. As recent researches have extend our understanding of pathogenesis, new agents targeted key pathologic mechanisms have been developed. Therefore, it is time to establish a new paradigm of treatment for children with atopic dermatitis since new biologics have been demonstrated to be effective and safe in children. The objective of this article is to review the clinical characteristics, severity classification, pathogenesis, and treatment, in particular, biologics already approved/undergoing clinical trials for children with atopic dermatitis.

Food allergies can pose significant risks and profoundly impact the quality of life of children and their families, making them a major public health concern. Allergen avoidance has been the traditional mainstay of treatment; however, recent research has focused on various approaches to food allergen immunotherapy. This review summarizes the recent advancements in oral, sublingual, and epicutaneous immunotherapies, highlighting their respective advantages and disadvantages. The ultimate goal of food allergen immunotherapy is to maximize efficacy while minimizing risks, leading to the exploration of strategies such as low-dose immunotherapy and the use of biologics. When selecting candidates for immunotherapy among patients with food allergies, factors such as allergen characteristics, the likelihood of natural resolution, age, symptom severity, and impact on quality of life require consideration, and an individualized approach should be adopted to determine the most suitable treatment method.

PURPOSE: Infantile atopic dermatitis (AD) is one of the most important risk factors for development of childhood asthma. Those with persistent wheezing with atopy had a great risk of declining lung function. Our study was designed to find out the risk factors for wheezing in infants who has AD, therefore early detection of risk factors for developing wheezing. METHODS: Three hundreds forty seven infants with AD who visited on our Pediatric Allergy Respiratory Center in Soonchunhyang University Hospital from January 2002 to December 2005 were enrolled and they were followed up till July 2006. We obtained familial allergy history and laboratory data such as serum total IgE, specific IgE and blood eosinophil count. We analyzed the factors affecting recurrent wheezing and persistent wheezing after 3 years old in children who had AD during infancy. RESULTS: One-hundred ninety-four children (55.9%) developed wheezing. Male sex (adjusted odds ratio (aOR) 1.7, 95% CI 1.1-2.7) and asthma history of parents or siblings (aOR 4.7, 95% CI 1.7-12.5) were the significant risk factors for development of wheezing. Serum total IgE (aOR 5.1 95% CI 1.1-22.5) and house dust mite sensitization (aOR 9.0, 95% CI 0.9-89.4) were significant risk factors for persistent wheezing after first three years of life. CONCLUSION: We should be alert for asthma in cases of infantile AD especially in male sex or with familial asthma history. And we propose early identification and intervention for asthma in infantile AD with increased total IgE and with house dust mite sensitization.

OBJECTIVES: We aimed to evaluate discrepancies between self-awareness of memory functions and actual memory functions in the elderly community. METHODS: A total of 369 individuals aged over 65 years from four elderly community centers completed clinical evaluation, neuropsychological batteries of the Korean version of the Consortium to Establish a Registry for Alzheimer's disease (CERAD-K), the Geriatric Depression Scale (GDS), the Instrumental Activities of Daily Living (IADL), and the Hachinski Ischemic Score. RESULTS: Among the elderly particpants, 26.3% showed incorrect awareness regarding their memory function. Those with subjective memory complaints included 73.5% with no memory impairment, while those without memory complaints included 11.3% of those with amnestic mild cognitive impairment (aMCI) and 4.3% of those with Alzheimer's disease (AD). Subjective memory complaints were significantly associated with depression. Among the elderly with no memory complaints, incorrect awareness was associated with 'no previous education' (OR 3.6, 95% CI 1.3-9.8), 'age over 80' (OR 2.4, 95% CI 1.1-5.4), and 'male' (OR 2.3, 95% CI 1.0-5.2) ; however, it was not significantly associated with depression. CONCLUSION: Incorrect awareness of memory impairment is prevalent among the elderly. Further, elderly individuals of an advanced age with no education may have memory impairment without memory complaints.

PURPOSE: We aim to compare clinical severity of atopic and non-atopic eczema in children and examine the relationship between total-IgE, eosinophil counts, Eosinophil, Eosinophil cationic protein (ECP) and clinical severity of atopic dermatitis (AD). METHODS: A total of 271 children diagnosed with AD at the Pediatric Allergy Respiratory Center in Soonchunhyang University Hospital from October 2005 to March 2008 were enrolled for this study and divided into 2 groups: atopic and non-atopic eczema. Serum concentrations of total- and specific-IgE, eosinophil counts and ECP were measured. Allergy skin tests were also performed and the SCORAD index was used to evaluate clinical severity. Comparisons the SCORAD index and serum total-IgE, eosinophil count and ECP between the 2 groups were made. RESULTS: Of the 271 patients, 162 (59.8%) were included in the atopic eczema group, while 109 (40.2%) were included in the non-atopic group according to the laboratory results. Serum total- IgE, eosinophil counts, ECP, the SCORAD index and the frequency of a family history of eczema were relatively higher in the atopic group. In the atopic group, serum total-IgE, eosinophil counts and ECP each had a statistically significant correlation with the SCORAD index with eosinophil counts showing the highest correlation. However, only eosinophil counts had a statistically significant correlation with the SCORAD index in the non-atopic group. CONCLUSION: Serum total-IgE, eosinophil counts, and ECP can be used as markers for clinical severity in patients with atopic eczema, while eosinophil counts be used as marker for clinical severity in those with non-atopic eczema.

Gender differences in asthma have been observed with a preponderance of boys affected before puberty and girls during and after puberty. The known influences of the menstrual cycle on asthma support a role for female sex hormones on the changing expression of asthma during adolescence. The purpose of this study was to investigate obesity, the menstrual cycle and lung function in adolescent girls. One hundred and three female high school girls (mean age: 15.9+/-0.8 yr) were enrolled. The investigation was performed using a questionnaire that included history of asthma, the menstrual cycle, other combined allergic disease and obesity. The skin prick and pulmonary function test during menstruation period and non-menstruation period. Analyses of these factors were compared. The forced expiratory volume in one second (FEV(1))/forced vital capacity (FVC) was significantly lower in the obese group compared to the non-obese group (99.8+/-13.8 vs. 107.1+/-10.2, p=0.03). The FEV(1) was significantly lower in the girls during menstruation period than in the girls who were not on menstruation (77.5+/-10.2 vs. 80.4+/-8.6, p=0.03). Our results showed that changes of pulmonary function were related to menstrual cycle and obesity in Korean adolescent girls.
