Effects of an intensive asthma education program on asthmatic children and their caregivers / 소아과

PURPOSE: Asthma is one of the most common chronic childhood disease. Education of asthmatic children and their families about asthma and its management may improve disease control, reduce symptoms, and improve school performance. The aim of the study was to evaluate the effects of an intensive asthma education program in asthmatic children and their families on outcome measure of asthma management behavior scale, knowledge about asthma, self efficacy scale and quality of life. METHODS: Fifteen asthmatic children and their families were invited the intensive asthma education program which including allergen avoidance, management of asthma, correct use of the inhalation devices and control of exercise-induced asthma (study group). Fifteen asthmatic children and their families those who did not participate this program were served as control group. Participants were asked to complete a written questionnaire before and 3-month after the program. RESULTS: After completing the intensive education program, significant improvement of the childrens asthma management behavior scale (27.1 vs. 32.2, P=0.011), belief and knowledge about asthma (14.2 vs. 17.9, P<0.001), self efficacy (47.9 vs. 49.7, P=0.091) and quality of life (79.6 vs. 88.6, P<0.001) was noted in the study group by measuring questionnaires. There are increasing tendencies in parental asthma management behavior scale and knowledge about asthma. CONCLUSION: This intensive asthma education program is effective in improving asthma control, self efficacy and quality of life of asthmatic children. This should serve as a national model for family-based programs for asthmatic children and their families.

Changes in Bronchial Hyperresponsiveness in Children with Asthma / 소아알레르기및호흡기학회지

PURPOSE: The aim of this study was to investigate changes in bronchial hyperresponsiveness, total IgE, blood total eosinophil counts and serum eosinophil cationic protein (ECP), after treatment with inhaled corticosteroids or leukotriene modifiers in children with asthma. METHODS: Methacholine bronchoprovocation tests were repeated at 12 months of follow-up in 37 children with atopic asthma and eight children with non-atopic asthma, who regularly attended the Allergy Clinic of Korea University Anam Hospital and Seoul National University Hospital over one year from their initial visit. A serum total IgE, peripheral blood eosinophil counts, and serum ECP levels were measured on their initial visits and at 12 months of follow-up. RESULTS: Following six to 12 months of inhaled corticosteroids or leukotriene modifiers treatment, the geometric mean (range of 1 SD) of methacholine PC20 was significantly changed in the atopic asthma group [2.20 mg/mL (0.41-11.82) vs. 6.69 mg/mL (1.25-35.87), P=0.000] but not in non-atopic asthma group [2.41 mg/mL (0.90-6.42) vs. 2.46 mg/mL (0.62-9.78), P=0.065]. Blood total eosinophil counts and serum ECP levels decreased significantly over one year in atopic asthma, while these changes were not observed in non-atopic asthma. Significantly higher FEV1 %predicted values (98.3+/-6.6%) were noted at 12 month follow-up compareed to the initial values (92.9+/-11.4%, P=0.023) in the non-atopic asthma group. CONCLUSION: Inhaled corticosteroids or leukotriene modifiers treatment resulted in a significantly decreased bronchial hyperresponsiveness in children with atopic asthma. This effect was reflected primarily by reduced blood eosinophilic inflammation. The persistence of bronchial hyperresponsiveness in children with non-atopic asthma might be related with genetic factors or airway remodeling other than eosinophilic inflammation.

Bacterial Contaminations of Home Nebulizers in Asthmatic Children / 소아알레르기및호흡기학회지

PURPOSE: Nebulizers are commonly used to treat children with asthma. Some pulmonary infections associated with contaminated nebulizer units have been reported. The aims of this study were to determine whether home nebulizers are repositories of bacteria and to ascertain how asthmatic patients use and maintain their nebulizers at home. METHODS: Fifty-five children with asthma aged 2 to 6 years were enrolled in this study. The parents were asked to bring their child's nebulizer units to regular follow-up visits. Bacterial samples which were obtained from the masks(or mouthpieces), nebulizer chambers and throat swabs were inoculated to blood agar, chocolate agar, and McConkey agar. Cultures were incubated at 5 percent CO2 incubator and observed after 24 hours. Parents completed a questionnaire regarding nebulizer usage and care in their child. RESULTS: Bacterial contamination was found in samples from 27(49.1%) of the 55 masks(or mouthpieces) and 24(43.6%) of the 55 chambers. The predominant microorganisms isolated were Acinetobacter baumannii, Bacillus subtilis, Klebsiella pneumoniae, Staphylococcus aureus, and Candida albicans. The questionnaire revealed that 40 parents cleaned the nebulizer units with tap water(and soap) and dried then, as they had received cleaning and drying instructions from a medical staff member. Seven organisms from nebulizer units were indistinguishable from the patient's throat isolates. CONCLUSION: We have demonstrated that home nebulizers in these asthmatic children were frequently contaminated with aerobic bacteria. Aerosolization might transmit these bacteria to their upper respiratory tracts. The education and training of home caregivers should include the principles of cleaning and maintenance of their child's nebulizer units.

Reconstruction of Anterior Cruciate Ligament with Iliotibial Band Transfer / 대한정형외과학회잡지

Ligamentous injury of the knee which could be easily occur in sports or traffic accidents resulted in more and severe disability than that of other joints. Rupture of the anterior cruciate ligament which restrain hyperextension, excessive rotation and anterior motion of tibia on femur is the most frequent and significant injury of the knee. Its treatment and clinical significance is one of the most controversial issue and its incidence tends to increase. From 1983 to 1985, modified Scott operation were performed on 10 patients at the department of orthopedic surgery, Chung Ang university hospital. Following results are obtained. 1. No limitation of range of motion of the knee was developed. 2. Intra-articular fixation by use of pull-out wire was done and special consideration was done for the site of fixation on tibia plateau and method of dilatation of posterior capsule. 3. Of the ten patients, nine had negative anterior drawer test, postoperatively.
