Background: Many young children suffer from wheezing illness during viral respiratory infection, and some of them experience wheezing many years later and ultimately develop bronchial asthma. It is not clear whether atopy or bronchial hyperresponsiveness in the family is a significant risk factor for asthma in this clinical setting. Objective : To examine the genetic basis for the development of asthma after early childhood wheezing. Materials and methods : A measurement of serum total IgE concentration, skin prick test to common inhalant allergens, and methacholine bronchial provocation test were performed in 29 asthmatic children and their parents, and 22 non-asthmatic children with the past history of wheezing illness during the first three years of age and their parents. A questionnaire was performed to assess the presence of asthma and allergic rhinitis in the parents. Results : Positive skin test response to common inhalant allergens was more prevalent in asthmatics than in non-asthmatics(67.8% vs. 27.2%). Serum total IgE concentration was significantly higher in asthmatics than in non-asthmatics(geometric mean: 173 vs. 83 IU/ ml). Positive skin test response to comman inhalant allergens was more prevalent in parents of asthmatics than in thoae of non-asthmatics(51.7% vs. 25.0%), but serum total IgE level was not different between the two groups(geometric mean: 132 vs. 120 IU/ml). Positive rate of methacholine bronchial provocation test, geometric mean of PC20-methacholine, and BR index were not different between the parents of asthmatics and non-asthmatics (18.1% vs. 13.9%; 164 vs. 180 mg/ml; 1.154+-0.077 vs. 1.055+-0.068, respectively). Conclusion : It is suggested that personal atopy is important in the development of asthma after early childhood wheezing, and parental atopy rather than bronchial hyperresponsiveness is a risk factor for the development of childhood asthma in this clinical setting.

Background: Chronic cough is commonly defined as a persistent or recurrent cough exceeding 3 weeks duration and the prevalence of chronic cough is reported to range from 14-23% among non-smoking adults. Irwin et al previously reported that common causes of chronic cough are postnasal drip syndrome asthma, and gastroesophageal reflux using the anatomic and diagnostic protocol. Objective: To determine the spectrum and frequency of chronic cough and to aid establishing algorithmic approach for chronic cough. Materials and metkod: We prospectively evaluated 105 consecutive and unselected immunocompetent patients complaining of chronic cough utilizing modified anatomic and diagnostic protocol proposed by Irwin et al. Initial diagnosis was made by history, physical examination and laboratory test including spirometry, methacholine provocation test, and 24 hour pH monitoring. Specific treatment was done based upon initial diagnosis and cough score was compared before and after treatment. Reassessment was done in case of treatment failure. Resalt: The causes of cough were determined in 100 of 105 patients(95% ). Cough was due to one condition in 94.8% and two in 15.2%. 121 causes of cough were identified and their spectrum and frequency were found to be postnasal drip syndrome (39.3% ), asthma (32.2% ), gasteroesophageal reflux (14.1%), chronic bronchitis (5.0%), others (4.1%: drug-induced, bronchiolitis, endobronchial tuberculosis, and lung cancer). History about nasal symptoms was useful, but history about gastroesophageal reflux were not useful for the diagnosis. Conclusion: The results suggest that anatomic and diagnostic approach for evaluating chronic cough is also useful in Korea and the most common causes of chronic cough are postnasal drip syndrome, asthma and gastroesophageal reflux.

Background: We have demonstrated recently that citrus red mite(Panonychus citri) is the most important allergen in citrus-cultivating farmers with asthma and/or rhinitis. Objective : A cross-sectional survey was performed to evaluate the sensitizat,ion to the citrus red mite and the effect of environmental exposure on the specific sensitization among primary school children living in rural areas of Cheju Island. Material and methods : A total of 4,490 children (from ages 7 to 12 years) living in rural are- as were enrolled in this study. Each subject was evaluated by a questionnaire developed by In- ternational Study of Allergy and Asthma in Childhood (ISAAC), and a skin prick test with 11 common inhalant allergens including citrus red mite. Results : On skin prick tests, the most common sensitizing allergen was Dermatophagoides pte- ronyssinus(7-9 years : 22.7%, 10-12 years : 25.5%), followed by D. farinae(20.4%, 21.8%), cockroach(9.6%, 12.8%), and citrus red mite(8.8%, 12.6%). The sensitization rate to citrus
