  • A large portion of the Korean population has been exposed to toxic humidifier disinfectants (HDs), and considering that the majority of the victims are infants, the magnitude of the damage is expected to be considerably larger than what has currently been revealed. The current victims are voicing problems caused by various diseases, including but not limited to lung, upper respiratory tract, cardiovascular, kidney, musculoskeletal, eye, and skin diseases, etc. However, there has been difficulty in gaining validation for these health problems and identifying causal relationships due to lack of evidence proving that toxic HD is the specific causes of extrapulmonary diseases such as allergic rhinitis. Furthermore, the victims and bereaved families of the HD case have not received any support for psychological distress such as post-traumatic stress disorder, depression, feelings of injustice, and anger caused by the trauma. In addition, because the underlying mechanisms of the toxic materials within the HDs such as polyhexamethylene guanidine phosphate, poly(oxyalkylene guanidine) hydrochloride, chloromethylisothiazolinone /methylisothiazolinone have yet to be determined, the demand for information regarding the HD issue is growing. The victims of the HD cases require support that goes beyond financial aid for medical costs and living expenses. There is a desperate need for government-led integrated support centers that provide individualized support through health screenings; in other words, we need an integrated facility that provides the appropriate social support to allow the victims to recover their physical and mental health, so as to well prepare them to return to a normal life. The implementation of such a plan requires not only the close cooperation between those departments already directly involved such as the Ministry of Environment and the Ministry of Health and Welfare, but also active support on a national scale from pan-governmental consultative bodies.

  • Purpose : 2009 Pandemic influenza A (H1N1) virus was identified in March 2009 and subsequently caused worldwide outbreaks. We described the clinical and epidemiological characteristics of H1N1 influenza infection. Methods : We used retrospective medical chart reviews to collect data on the visiting patients from a single institute. H1N1 infection was confirmed in specimens with the use of a RT-PCR (real time reverse transcriptase polymerase chain reaction assay). Result : 6,836 patients had H1N1 RT-PCR test, and 2,781 were confirmed with H1N1 virus infection. 158 patients (5.7%) had hospital treatment and inpatients were significantly younger (5.4${\pm}$3.3 years) than outpatients (7.5${\pm}$3.9 years) among H1N1 virus confirmed patients. Oxygen, steroid, immunoglobulin, ventilator treatment was provided in a substantial proportion among pneumonia patients accompanying wheezy respiration. In addition more intensive care was needed in patients accompanying segmental, lobar, interstitial, mixed pneumonia and lung effusion (27.2%) than patients with bronchopneumonia (7.3%) among H1N1 virus infection confirmed patients. Seventy-one infants had oseltamivir treatment out of 83 infants under 1 year, and no significant side effects and complications were identified. Conclusion : In 2009 pandemic influenza A (H1N1), hospital treatment was needed in younger patients. Early intensive care was needed in pneumonia patients accompanying wheezy respiration, and patients accompanying segmental, lobar, interstitial, mixed pneumonia and lung effusion.

  • Foreign bodies in food and air passage, especially the latter in infants and children requires emergency treatment. The frequent symptoms are coughing, wheezing, and dyspnea, So may be confused as asthma, pneumonia and acute Laryngitis. The species and incidence of the foregin bodies are variable according to the age, method of life, environment and economic condition. The authors experienced 35 cases of foreign body in air passage during the period of last 3yrs which were treated by ventilating Bronchoscopy, and thoractomy in this hospital. One of them was lead to death. The authors analysed above cases and report with it's literature consideration. Results: 1. The prevalent foreign bodies were peanut, metal, food particles in order of frequency. 2. In frequent symptoms were dyspnea, coughing and wheezing in the order. 3. In the age incidence, 48% of the foreign bodies were 1∼5yrs. 4. In sex distribution, male to female ratio was 2.1: 1 5. In duration of lodgment, 65% of the foreign body were removed within 24hrs. 6. Most prevalent site of the foreign body was Rt. main bronchus Rt. to Lt. ratis was 2 : 1 was 7. Treatment was done; 25 cases were by ventilating bronchoscopy.

  • The bronchoscopy is usually performed in the patients who present symptoms of wheezing, hemoptysis, signs of airway obstruction, unexplained long-term chronic cough with or without radiologic features of pneumonia, emphysema or atelectasis. The symptoms and signs of cases of suspected airway foreign body are of often cofused with those of asthma pneumonia and other respiratory tract disease. The ventilating bronchoscopy will be helpful for removal of certain foreign bodies as well as alleviating medically-unresponsive bronchopulmonary conditions via removing abnormal secretions or merely improving ventilation. The authors have performed clinical analysis of 59 patients who were suspected of airway foreign bodies and treated by ventilating bronchoscopy from September 1985 to February 1995. The results were as follows: 1) Among the 59 cases of bronchoscopy, 51 cases(97%) were under the age of 3. The ratio of male and female was 2.69:1 2) Most common presenting symptom was coughing(84.7%) followed by dyspnea, fever, wheezing and anterior chest pain. 3) Among 39 cases of identified foreign bodies, abnormal findings in the chest X-ray films were found in 33 cases(84.6%) and most common abnormal radiologic feature was pneumonia in 10 cases(25.6%) followed by combination of pneumonia and emphysema, or emphysema alone. All the 20 cases of absent foreign body presented abnormal radiologic features and common findings were pneumonia and atelectasis. 4) Vegetable foreign bodies were the most common form of removed airway foreign bodies(69.2%) followed by metallic foreign bodies(12.8%) and plastic foreign bodies(7.7%). 5) By distribution of the location of foreign bodies, 29 cases(74.4%) were located in the main bronchus( 16 cases of right side and 13 cases of left side), 8 cases were in the trachea and 2 cases were found at the cordal level. 6) By duration of foreign body lodgement in the airway, 9 cases(23.1%) were removed within 7 to 30 days, 10 cases(5.6%) within 3 days and 5 cases(12.8%) were enlodged over 30 days. 7) In the cases of absent foreign bodies, common bronchoscopic findings were mucopurulent or thick mucoid discharge in the main bronchi, erythema or edema of bronchial mucosa and all the cases were improved after ventilating bronchoscopy with concomitant medical management.

  • The Purpose of this study was to investigate the new effective oriential medicine tretments in pediatric disease and its clinical applicability The study was composed of 1245 new patients who had been treated at the all unit in the Dong-Seo oriential Medicine Hospitial for 1 year, from 1 April 1999 to 31 March 2000, and aged between 0 and 18 years. The chief complaint was mainly categorized by oral examination on patients and their care-givers. Result 1. The numbers of children who involved in this study is total 1245: Male children are 668 and female children are 577 children. The sex rate between male and female is 1.15 to 1. 2. Most of the above patients came to the hospital at first time from diseases such as musculoskelectal disease, weakness, asthma, cough, anorexia, common cold, rhiorrhea, sweating, dyspepsia, dematitis, night terror, obesity, stomach, short stature, Besides, they also came to the hospital at first time from various diseases such as epistasxis, pyrexia. Bell's palsy, nocturia, contipation, cerebral palsy, disorder, CVA. diarrhea. stress disease, Allergic disease, Tic disorder. Visual disorder, Kawasaki disease, Pierre Robin's syndrom, hematuria, edema and so on. 3. Looking at the frequent diseases, Respiratory dis. children including asthma, cough, rhiorrhea, sweating, common cold, pyrexia covers 36%, in 399 numbers. digestive dis. children including anorexia, dyspepsia, stomach, diarrhea, constipation, indigestion covers 19%, in 211 numbers. cadiovasculary disease children including arrthymia, terror in frequency, night crying, sediation, Tic disorder covers 8%, in 85 numbers. Hepatobiliary disease children including short stature, dizziness, visual difficulty, sprain, disorder of nail covers 21%, in 238 numbers. renal disease. children including nocturia, hematuria, hemation, disorder of hair, menorrhea, cerebral palsy, edema in 44 numbers. Fatigue children covers 13%. in 143 numbers. 4. In case of respatory disease children. total number is 399 children. dematitis children are 108 numbers and asthma children are 96 numbers. These show that children seem to the best have dematitis and asththma. The age from 0 to 6 is 290 numbers, covering 73 percentage. The others are covering 27 percentage. These data demonstrate that the age from 0 to 6 age could easily get these kinds - of diseases. The 29 percent of children had these kinds of diseases in spring. The 28 percent of children had these kinds of diseases in autumn. These show that children seem to frequently have these kinds of diseases in both spring and autumn season.(inter-season) 5. In case of digestive disease, anorexia covers 39%, in 83 numbers, dyspepsia covers 28%, in 59 numbers, anorexia and dyspepsia were the lagest group in digestive disease and the age from 0 to 6 covers 59%, in 125 numbers and the other age covers 39%. According to these data, infant seems to be vulnerable to these kinds of diseases. The 24 percent of children had these kinds of diseases in spring and summer. The 33 percent of children had these kinds of diseases in winter, which means that children mostly had winter. but decreased significant in autumn. 6. In case of cadiovasculary diseases, it can be divided into two categories: night covers 73% and nervous characteristics covers 27%. The age from 0 to 6 occupies 75%, and the other age occupies 25%. These data also show that infants can easily infected with these kinds of diseases. Analyzing by the season, summer could be the most frequent season that children have these kinds of diseases. but decreased in autumn. 7. In case of hepatobiliary children, sprains covers 166 numbers, fatigue covers 32 numbers, epistasxia covers 24 members, the reasion which sprain occupyied most of % were sprain covered ages. The age from 0 to 14 covers 59% and from 15 to 18 covers 41%. In the conclusion the adolescent seems to be vulnerable to sprains. In spring 29%, insummer 31%, in autumn 23%, and in winter 28% of children got these kinds of diseases, which show that children seems to have this kinds of disease in summer season. and decreased in autumn. 8. In case of renal disease. nocturia and hematuria covers 52%(occupied overhalf). The age from 0 to 6 covers 52%(occupied overhalf). Analyzing by season, in spring increased in summer(59%), decreased in autumn(45%) Conclusion 1. The chief complant in pediatric diseases that needed an oriental medical tretment was mainly the disease that tends to take iong time and the weakness. and appeared frequency in respiratory disease : 2. The oriential medical tretment was still preferred as a way to improve the weakness by patients, rather than a way to overcome their disease. In paticular, the study shows that the oriental medical tretment should be emphasized in terms of preventing the disease 3, The new disease, which were developed with the change of human life and envir oment(just like seual disorder, short stature, obesity, dynamic disorder, examinee disease), should be in vestigated as a new field of oriental medical tretment.

  • Purpose : The purpose of this study was to research whether measurement of cow's milk specific IgE on the newborn would be helpful in the diagnosis of cow's milk allergy. We tried to find out the relation between cow's milk specific IgE and other allergy diseases by following up cases. Methods : We reviewed clinical features of 87 episodes in infants less than 4 weeks old who were positive in cow's milk specific IgE test. For the study group, history taking, physical examinations, elimination and cow's milk specific IgE tests were carried out. We investigated the connection among cow' milk specific IgE, allergic disease and family history in 40 of 87 patients we could follow up on. Results : The mean age of the study group was $17.2{\pm}5.4days$. The subjects were classified in four groups according into allergens : 87 milk allergy positive patients, 24 casein positive, 38 ${\alpha}$-lactoalbumin positive, and 75 ${\beta}$-lactoglobulin positive. The number of patients who had follow-ups for more than 6 months to was 40(45.9 percent). The patients whose parents had allergic disease numberred 10(25 percent). Fiften patients had allergic diseases, 4 had asthma and 11 atopic dermatitis. According to the follow-up study, there is a significant relation between casein positive patients and allergic disease. But there is no statistical and significant relation between cow's milk specific IgE and a family history of allergic disease. Conclusion : For the newborn babies, elimination tests and cow's milk specific IgE tests can be useful in the diagnosis of IgE-mediated or mixed milk allergies.

  • Objectives : The purpose of this study was to propose appropriate strategic directions and road maps for successful achievement of programs preventing winter disease in the summer. Methods : Details on programs preventing winter disease in the summer such as clear concept, theoretical basis, current status, intervention or available prescriptions and indication/contraindication/caution were prepared through the related journal review, upon which an observational study was devised and done for simulation to find out even a trivial problem and to guarantee the safety beforehand. The experimental group was divided into 5 groups by the size of pill and the way ginger is treated; 1cm pill with ginger group, 3cm pill group without ginger, 3cm pill group dipped into ginger, 3cm pill group applying ginger to acupoints and 3cm pill group with ginger Results 1. program preventing winter disease in the summer was defined as representative winter diseases such as common cold, influenza, chronic asthma, chronic bronchitis, allergic rhinitis, emphysema, chronic gastritis and rheumatoid arthritis, and preventive care in the summer, reinforcing deficient yang qi of five viscera by using exuberant yang qi from summer heat. 2. It was based upon historically established theories which is 'nourishing yang qi in the spring and summer', 'long summer, namely rainy spell in the summer overwhelms the winter, because of earth winning water according to the five phases theory' and 'To replenish yang qi is major principle to treat winter diseases, which can be most appropriately and timely applied to the patient with deficient yang qi of five viscera inherently, especially in the three dog days of the summer, because of exuberant exterior yang qi and deficient interior yang qi in the five viscera'. 3. In the adjacent China and Taiwan, acupoint applying method in the three dog days named 'San Fu Tie' have been stirring a boom throughout the nation, in which Xiaochuan Gao was used as a basic prescription and it mainly was applied at bilateral $BL_{13}$, $_{15}$ and $_{17}$ for about 4 hours. As far as domestic current status, the necessity of adopting the above method prior to Herbal formula was also recognised, because not a few koreans have apprehension for the safety of it including medicinal herbs and are reluctant to take it any more due to negative advertisement of narrow minded doctors' association. 4. Indication of acupoint applying method in the three dog days included most of winter diseases such as common cold, influenza, chronic asthma, chronic bronchitis, allergic rhinitis, emphysema, chronic gastritis. contraindication was pregnant woman and the weak such as infants and the old. More attention was paid to grasp firmly the normal reaction following the treatment for preventing side effect and teasing blister. recommendation was also given to abstain from food inducing phlegm and dampness such as meat, shrimp and crab as well as cold drinks and foods 5. In the simulation observational study based upon the above findings following review the related articles, no blister was shown on the acupoints icluding bilateral $BL_{13}$, $_{15}$ and $_{17}$ in every experimental group during 24hr observation following the acupoint applying treatment with pills made by modified and devised prescription. At 4 hr, the effectiveness of it reached a peak showing redness and mild tenderness and there is little difference between groups 3cm pills groups regardless of the way ginger was treated. abdominal distention and growling was found in all the volunteers during the treatment at CV 8. Strategic directions and road maps : Through successful fulfillment of the program preventing winter disease in the summer, Korean traditional medicine should be integrated into mainstream national health care services. Cultural access was thought to be as important as Scientific EBM approach. First of all, To evoke potential cultural homogeneity from campaigns and press advertisement was needed for promoting public awareness about preventing winter disease in the summer by enhancing immunity via acupoint applying treatment in the three dog days, and then indigenous name as Sambokcheop, protocol, Clinical Research Form for data collection of it should be developed and prepared. Once the first step was taken this summer, through a thorough data collection and scrutinized scientific evaluation, drawbacks should be compensted for and the efficacy and safety should be substantiated.

  • Background : Many clinicians are reluctant to prescribe systemic corticosteroids to manage an asthmatic attack because of many complications such as osteoporosis, cushing's syndrome, diabetes, hypertension and bleeding tendency. The use of nebulized budesonide may be of value in some infants, old men, and in particular adult asthmatic patients who complain of severe dyspnea. A clinical validation and steroid-sparing effect of nebulized budesonide in asthmatic adults and COPD were evaluated, and the short-term effects of budesonide use on the HPA axis were assessed. Materials and Methods : Study A was prospectively done with 41 patients diagnosed with pure asthma and 30 patients diagnosed with COPD (including asthmatic component) in Soonchunhyang Hospital, Chunan from June. 2000 to Sep. 2001. They were treated with nebulized budesonide including systemic steroids (Group 1), a budesonide tubuhaler including a systemic steroid (Group 2), or only the systemic steroid(Group 3). The peak flow rate, arterial blood gas in room air, pulmonary function test, symptom scoring, steroid amount and hospital stay were analyzed. Study B was conducted with 19 patients to evaluate the short-term effects on the HPA axis of treatment with nebulized budesonide 1mg twice daily and a budesonide turbuhaler 5 puffs twice daily. The adrenal function was assessed prior to budesonide inhalation and after 7 days of budesonide inhalation. Results : In the pure asthmatic patients, the mean value of the symptoms (dyspnea, wheezing, cough, night asthma) or the arterial BGAs, total amounts of steroid or hospital stay and the difference in the results of the pulmonary function tests or peak expiratory flow rate were similar in the three groups. In COPD with an asthmatic component, there were no significant differences among the three groups. Although nebulized budesonide suppressed HPA function,(p=0.006) the HPA responses from the nebulized budesonide and turbuhaler budesonide were similar (p=0.288) Conclusion : This result suggests that systemic steroid should only be made available for acute asthmatic patients irrespective of the inhaled budesonides. Nebulized budesonide at the therapeutic dose has similar effects on the HPA axis compared to that of turbuhaler budesonide.

  • Purpose : Breast milk contains several components that provide specific immunity and affect the maturation of the infant's immune system. Allergic disease (AD), including atopic eczema, asthma, allergic rhinitis, and food allergy is characterized by an imbalance between cytokines produced by distinct T-helper cell subtypes. The aim of the study was to investigate the concentrations of cytokines and chemokines that were involved in allergic reactions in breast milk from allergic and nonallergic mothers and then analyse the effect of breastfeeding duration on the prevalence of allergic disease in the age of two. Methods : The breast milk samples were collected from mothers with AD (n=88) and without AD (n=47). Breast milk was collected at the second day (colostrum) and four weeks later (mature milk).The level of Interlukine (IL)-4, IL-5, IL-6, IL-8, IL-10, IL-13, $TGF-{\beta}1$, $TGF-{\beta}2$, RANTES in breast milk were determined by commercially available enzyme-linked immunosorbent assay (ELISA) kits according to the manufacturer's instructions. Results : Mothers with AD had a higher concentration of IL-8 in colostrum compared with those without AD (P=0.021). But, $TGF-{\beta}1$ and $TGF-{\beta}2$ were higher concentrated in colostrum of mother without AD (P=0.013, P=0.001). Whereas concentrations of other cytokines were not significantly different between the two groups. There was no association between levels of cytokines and chemokines in the breast milk and allergic development during the first 2 years of life in the infants. Conclusion : The higher concentration of $TGF-{\beta}1$ and $TGF-{\beta}2$ in colostrum from non-allergic mothers may explain the protective effect. But, the higher concentrations of IL-8 in colostrum from allergic mothers may in part explain the controversial results on the protective effect of breastfeeding against allergic diseases. We conclude that there is no convincing evidence form a relation between cytokines in breast milk and allergic diseases in infants. Longer follow-up are necessary to evaluate the effects of breast milk components on AD.

  • Objective: The objective of this study was to describe the characteristics of exposure to humidifier disinfectants (HDs) and their association with the presence of a person who experienced the adverse health effects in general households in Korea. Methods: During the month of December 2016, a nationwide online survey was conducted on adults over 20 years of age who had experience of using HDs. It provided information on exposure characteristics and the experience of health effects. The final survey respondents consisted of 1,555 people who provided information on themselves and their household members during the use of HD. Exposure characteristics at the household level included average days of HD use per week, average hours of HD use per day, the duration within which one bottle of HD was emptied, average input frequency of HD, amount of HD (cc) per one time used, and active ingredients of HD products (PHMG, CMIT/MIT, PGH, or others). The risk of the presence of a person who experienced adverse health effects in the household was evaluated by estimating odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for monthly income and region using a multiple logistic regression model. Subgroup analyses were conducted for households with a child (≤7 years) and households with a newborn infant during HD use. Results: The level of exposure to HD tended to be higher for households with a child or newborn infant for several variables including average days of HD use per week (P<0.0001) and average hours of HD use per day (P<0.0001). The proportion of households in which there was at least one person who experienced adverse health effects such as rhinitis, asthma, pneumonia, atopy/skin disease, etc. was 20.6% for all households, 25.3% for households with children, and 29.9% for households with newborn infants. The presence of a person who experienced adverse health effects in the household was significantly associated with average hours of HD use per day (Ptrend<0.001), duration within which one bottle of HD was emptied (Ptrend<0.001), average input frequency of HD (Ptrend<0.001), amount of HD per one use (Ptrend=0.01), and use of HDs containing PHMG (OR=2.23, 95% CI=1.45-3.43). Similar results were observed in subgroup analyses. Conclusion: Our results suggest that level of exposure to HD tended to be higher for households with a child or newborn infant and that exposure to HD is significantly associated with the presence of a person who experienced adverse health effects in the household.
