ABSTRACT
PURPOSE: Although allergic disease has been recognized as a common chronic disease related to the sleep disturbance of children, studies on sleep disturbance in children with allergic disease are scanty in Korea. The aim of this study was to evaluate the sleep disturbance of children with allergic disease. METHODS: Children aged 2 to 12 years were assessed using the sleep questionnaires. From July 2011 to June 2012, surveys were conducted on patients who were diagnosed with allergies in 3 general hospitals and in an elementary school in Seoul and the capital area. The analysis was done in 3 groups according to age. RESULTS: The sleep questionnaires of 1,174 children were evaluated. Children with allergic disease were 341 (209 males and 132 females) and those in the control group were 833 (428 males and 405 females). Parasomnia symptoms were common in young children (ages 2 to 5 years) than in the control group (P<0.05). Symptoms of sleep-disordered breathing were more common in early adolescent children (ages 11 to 12 years) than in the control group (P<0.05). The presence of allergic rhinitis, gender, and body mass index did not correlate with a sleep disturbance in children with allergic disease. CONCLUSION: To our knowledge, this study was the first report of sleep disturbance in children with allergic disease in Korea. This study suggests that children with allergic disease from early children may have poor sleep quality than those without. Therefore, proper treatment of and great interest in sleep disturbance are required for children with allergic disease.

PURPOSE: The goal of this study was to measure bilirubin levels over 6 hours using a transcutaneous bilirubinometer. The change in the bilirubin levels were recorded in a nomogram. The natural progress of jaundice in neonates was monitored using the nomogram and cases were identified that needed further follow-up observation and treatment. METHODS: The subjects of this study were 986 healthy term or near-term infants at the age of 35 weeks or older who were born at Sung-Ae General Hospital during the period from October 1, 2007 to April 30, 2009 and whose parents were both Koreans. Transcutaneous bilirubin measurements were obtained using a transcutaneous bilirubinometer (Minolta, JM-103) from 6 hours of life to discharge at intervals of 6 hours. A nomogram was derived from the obtained data and compared to the delivery method, gestational age, and feeding method. RESULTS: Percentile graphs were drawn according to time. Based on the graphs, phototherapy was necessary in more than 90 percent of the infants between 35 and 37.6 weeks of age and in 95 percent of the infants 38 weeks and older. The mean bilirubin level at 24, 48, 72 and 96 hours after birth were compared according to the delivery method, gestational age, and feeding method. The bilirubin level in 48 hours was significantly higher in neonates born via cesarean section delivery compared to the neonates born via vaginal delivery, however the levels were not statistically different at the other hours. CONCLUSION: The results of this study show the nomogram derived from hour-specific transcutaneous bilirubin levels. This information can be used to predict the risk for subsequent significant hyperbilirubinemia.

PURPOSE: The prevalence of atopic dermatitis (AD) has been increased in Korea. We aim to investigate the risk factors for development of AD in infants, especially those factors related to the family history. METHODS: The data from 542 infants in our prospective birth cohort study were analyzed. The data from their parent were collected by questionnaires and skin prick tests. They were regularly followed up at 1 year of age when the presence of AD and allergen sensitization was determined. Various factors such as sex, cesarean section delivery, duration of breast feeding, presence of siblings, vaccination, antibiotic use and pet keeping were also assessed. RESULTS: AD developed in 109 infants (20.4%). In univariate analysis, the presence of either maternal or paternal allergic diseases increased the risk for development of AD in their infants. Multivariate logistic analysis, however, showed that only the presence of maternal allergic diseases correlated with the development of AD (P=0.018). While AD developed in 14.7% in infants of parents with no allergic history, the incidences of AD in infants with a single parent allergy history and in those with 2 parent allergy history were 27.0% and 41.7%, respectively. Their adjusted relative risks (95% confidence intervals) were 1.85 (1.24-2.89) and 2.93 (1.68-4.96), respectively. CONCLUSION: Parental allergic diseases, especially maternal allergic diseases, are possible risk factors for development of AD in Korean infants.

PURPOSE: Histologic classification plays a key role in the classification of idiopathic interstitial pneumonia (IIP) into clinically meaningful categories in terms of natural history, prognosis and treatment. The implications of histological diagnosis, clinical features and prognosis in children has not been described. This study aimed to analyze the clinical features of IIP in children. METHODS: A total of 15 patients with IIP were recruited, who had a surgical lung biopsy. The age, sex, symptoms, initial oxygen saturation, radiologic findings and clinical courses were retrospectively investigated. RESULTS: The median age at diagnosis was 3 years. Cough (93.3%), tachypnea (86.7%) and dyspnea (80%) were the most common symptoms, and laboratory findings were nonspecific. Acute interstitial pneumonia (n=6), chronic pneumonitis of infancy (n=4) nonspecific interstitial pneumonia (n=3) were relatively common. All patients received corticosteroid therapy and the mortality rate was 26.7% (n=4). CONCLUSION: IIP has diverse clinical features according to subtypes. Knowledge of the underlying histopathology will allow the prediction of more accurate prognosis, the decision of appropricate therapy, and the clinical investigation of novel therapeutic agents in patients with IIP.

PURPOSE: Mycoplasma pneumoniae pneumonia is one of the most common community- acquired pneumonias in childhood. Recently, it has tended to occur at a young age. We reviewed clinical manifestations of M. pneumoniae pneumonia in the young. METHODS: A total of 378 children who were admitted to the Bundang Jesaeng Hospital due to M. pneumoniae pneumonia from 2003 to 2006 were retrospectively analyzed. M. pneumoniae infection was confirmed by mycoplasma antibody titer >1:320 or four-fold increase of titer. The children were divided into an infant group (Group A, 0-4 years) and an older children group (Group B, 4-14 years). We analyzed the differences between the two groups according to incidence, clinical manifestations, laboratory and radiologic findings. RESULTS: The number of patients in Group A was 147 (38.9%) and in Group B, 231 (61.1%), respectively. Seasonal distribution showed the highest frequency in autumn and the lowest frequency in spring in both groups. The most common symptom was cough (98.6% and 96.5%, respectively) and fever (85.7% and 91.3%, respectively). The most common physical findings were crackle (72.8% and 73.3%, respectively). The common radiologic findings were lobar pneumonia in both groups (55% and 76.1%, respectively), followed by bronchopneumonia (29.2% and 11.6%, respectively). Group A had a lower incidence of high antimycoplasma antibody titer (>1:5,120) and severe pulmonary complication than Group B. CONCLUSION: Group A had the more incidence of sputum production, leukocytosis, bronchopneumonia and duration of fever less than 7days. Group B had the more incidence of weak breathing sound, lobar pneumonia and duration of fever more than 7days.

PURPOSE: Foreign body aspiration in the tracheobronchial tree is a common medical emergency in children and represents an important cause of morbidity and mortality. This study was aimed to analyze the clinical spectrum of tracheobronchial foreign bodies in children and to evaluate the causes of late diagnoses. METHODS: A total of 108 patients with foreign body aspiration were recruited in the last 10 years, who had a flexible or rigid bronchoscopic examination. The age, sex, symptoms, causes of aspiration, radiologic findings, and clinical courses were investigated retrospectively. Patients were divided into 2 groups according to the elapsed time from aspiration to a definite diagnosis as early (24 hours after aspiration). The two groups were compared for clinical courses, radiologic findings, and the duration of admission of early- and late-diagnosed foreign body aspiration. RESULTS: Approximately 80% of the patients were less than 24 months of age and the most common symptoms were the sudden onset of a cough. Hyperinflation or obstructive emphysema (52.8%) and normal chest radiographs (19.4%) were the most frequent radiologic findings. Plain chest radiographies revealed visible foreign bodies in 7.4% of all patients with foreign body aspiration. Nuts were the most common foreign bodies aspirated. Sudden onset of a persistent cough and fever were predominant in the late-diagnosed group.(P<0.05) CONCLUSION: Our results suggest that clinical suspicion upon interviewing is enough to indicate bronchoscopy. The best way to reduce the number of accidents and deaths associated with foreign body aspiration is to promote public prevention polices.

PURPOSE: The aim of this study was to investigate the causes of stridor with respiratory distress and their clinical courses in children. METHODS: Children who were hospitalized in Samsung Medical Center due to stridor with respiratory distress without infectious causes were studied retrospectively. The causes of stridor, sex, age at onset, symptoms, combined diseases, treatment, and clinical courses were investigated. Fisher's exact test was used to assessing the association of risk factors with the severity of post-intubation subglottic stenosis. RESULTS: Of 75 cases, 15 (20 percent) were congenital and 60 (80 percent) were acquired. The prevalence in males was higher than in females. Common causes of congenital stridor were laryngomalacia, tracheomalacia, pulmonary artery sling and complete tracheal ring. Acquired stridor is usually due to subglottic stenosis secondary to endotracheal intubation. Risk factors such as frequency and duration of intubation, age at first intubation, birth weight and gestational age were not associated with the developement of post-intubation subglottic stenosis. (P> 0.05) More complicated surgical treatment was required according to the severity of subglottic stenosis. CONCLUSION: Congenital malformation of the airway requiring urgent surgical correction should be differentiated in children with stridor and respiratory distress. Post-intubation subglottic stenosis accounts for most cases of acquired stridor. Evaluation of it's severity, and careful airway care, is required in children with subglottic stenosis.

PURPOSE: This study aimed to compare the clinical outcome of acute poststreptocaccal glomerulonephritis (APSGN) between patients who had presented with gross hematuria and those with microscopic hematuria. METHODS: Thirty-nine patients with acute poststreptococcal glomerulonephritis, who were diagnosed from January 2000 to April 2003 were enrolled. RESULTS: The mean age was 8.85 years and the male to female ratio was 1.1:1. Seventeen patients presented with gross hematuria at diagnosis(group A) and twenty-two patients had microscopic hematuria only(group B). There were no significant differences between the two groups in the incidence of edema, fever or history of respiratory infection and oliguria. But hypertension was more frequent in group B. Laboratory data showed decreased C3 and C4 level in group B. Spot urine protein/creatinine ratio and 24hr urine protein showed higher levels in group A. CONCLUSION: Patients with gross hematuria at diagnosis had lower incidence of hypertension and a higher rate of nephrotic range of proteinuria than patients with microscopic hematuria. However, no difference in the duration of admission or complication rate was observed. All patients had clinical improvement during follow-up. We conclude that gross hematuria is not a significant prognostic factor for poststreptococcal glomerulonephritis.

PURPOSE: This study is to evaluate the effect of intrauterine growth retardation on the mortality and morbidity in extremely low birth weight infants (ELBWI). METHODS: As retrospectively reviewing 266 ELBWI who were admitted to the neonatal intensive care unit of Samsung Medical Center, the effects of intrauterine growth on mortality and morbidity in ELBWI was assessed by comparing appropriate for gestational age (AGA) ELBWI to small for gestational age (SGA) ELBWI. RESULTS: The number of SGA and AGA infants was 65(24%), 201(76%) respectively. The mean gestational age of the SGA infants (28(+6)+/-2(+3) week) was significantly higher than in the AGA infants (26(+2)+/-1(+3) week) (P<0.001). The mean birth weight of the SGA infants (755+/-173 g) was significantly less than in the AGA infants (830+/-118 g) (P< 0.001). The mortality of the SGA infants (29%) was less than in the AGA infants (33%). However, when adjusted for gestational age, there was no statistically significant difference. The incidence of respiratory distress syndrome of the SGA infants (66%) was significantly lower than in the AGA infants (87%). The incidence of bronchopulmonary dysplasia of the SGA infants (20%) was lower than in the AGA infants (23%). However, when adjusted for gestational age, there were no statistically significant differences. There was no statistically significant association of SGA with intraventricular hemorrhage, retinopathy of prematurity and necrotizing enterocolitis. CONCLUSION: There was no statistically significant association of intrauterine growth retardation with mortality and morbidity in ELBWI.
