Purpose: Human parechovirus (HPeV) is an increasingly recognized pathogenic cause of central nervous system (CNS) infection in neonates. However, HPeV infections have not been studied in older children. This study determined the prevalence and clinical features of HPeV CNS infection in children in Korea. Methods: Reverse transcription polymerase chain reaction assays were performed using HPeV-specific, 5' untranslated, region-targeted primers to detect HPeV in cerebrospinal fluid (CSF) samples from children presenting with fever or neurologic symptoms from January 1, 2013, to July 31, 2014. HPeV genotyping was performed by sequencing the viral protein 3/1 region. Clinical and laboratory data were retrospectively abstracted from medical records and compared with those of enterovirus (EV)-positive patients from the same period. Results: Of 102 CSF samples, six (5.9%) were positive for HPeV; two of 21 EV-positive samples were co-infected with HPeV. All samples were genotype HPeV3. Two HPeV-positive patients were <3 months of age and four others were over 1 year old. While HPeV-positive infants under 1 year of age presented with sepsis-like illness without definite neurologic abnormalities, HPeV-positive children over 1 year of age presented with fever and neurologic symptoms such as seizures, loss of consciousness, and gait disturbance. The CSF findings of HPeV-positive patients were mostly within the normal range, whereas most (73.7%) EV-positive patients had pleocytosis. Conclusions: Although HPeV is typically associated with disease in young infants, the results of this study suggest that HPeV is an emerging pathogen of CNS infection with neurologic symptoms in older childhood.

The purpose of this study is to develop music psychotherapy program applying the Inner Family System(IFS) to reduce adult depression and improve self-esteem and to verify its effectiveness. For this, literature search and theoretical basis were prepared, and validity was secured through a demand survey and evaluation by experts. After going through the preliminary program, the final program consisting of 10 sessions was developed after revision and supplementation. To verify the effectiveness of the program, 25 people who met the selection criteria with a score of 20 or higher on the Depression Scale(CES-D) were selected. Of the 25 subjects, 10 subjects in the experimental group, 10 subjects in the control group, and 5 subjects in the preliminary group were randomly assigned and analyzed as final study subjects. The experimental group performed 10 sessions of music psychotherapy applying IFS twice a week for 90 minutes, and the control group did not receive any treatment. As a result of data analysis, first, it was confirmed that there was a difference between the experimental group and the control group in the change patterns according to the measurement period of overall depression and the sub-factors, depressive emotion, interpersonal emotion, and physical depression score. Second, the effects were statistically significant on overall self-esteem and sub-factors such as self-deprecation, relationship with others, leadership and popularity, assertion and anxiety. Third, it was confirmed that the pattern of change according to the measurement period of the IFS score differed between the experimental and control groups.

Purpose : Hepatitis A viral infections have been continued after re-emerging since mid 1990s in Korea. The incidence of this disease has been increased in young adults younger than 30 years of age since 2000. This study was performed to evaluate the prevalence of antibody to hepatitis A in Korea(two regions; Incheon and Changwon) in 2005, and was compared with the results of similar studies in mid 1990s. Methods : The study was conducted from January 2005 to June 2005, and consisted of 1,301 enrolled subjects, neonates to 50 years old, living in Incheon and Changwon in Korea. All sera were frozen and stored at $-70^{\circ}C$ until assayed. Anti-HAV IgG antibodies were measured by microparticle enzyme immunoassay(HAVAB, Abbott Lab., IL, USA). Results : The prevalence of anti-HAV IgG was 61.1% in infants younger than 1 year old, 30.5% in 1~5 years, 14.6% in 6~10 years, 1.7% in 11~15 years, 6.5% in 16~20 years, 36.6%in 21~30 years, 77.5% in 31~40 years, and 99.8% in 41~50 years. Statistical differences were not found between male and female, but there was statistical difference in 6~10 years old age group between the two areas. Conclusion : Our study indicate that the prevalence of antihepatitis A virus antibody has shifted from children to old adolescents and young adults. This result suggests that the risk of sudden outbreaks or increasing incidence of hepatitis A viral infections in young adults may be expected in our society. The preventive strategies of hepatitis A including vaccination should be prepared.

Purpose : Some patients develop side effects from theophylline even at low serum concentrations. We designed a prospective study to evaluate the side effects of theophylline. Methods : A Prospective, controlled trial study was conducted. The low-dose group received an intravenous continuous aminophylline dose of 5 mg/kg/day on the first day and subsequently 10 mg/kg/day on the following two days. The usual-dose group received 10 mg/kg/day for three days and the control group received normal saline for three days. Heart rate, respiratory rate, serum concentration of theophylline, and four adverse events (irritability, sleep disturbance, jitter, and vomiting) were checked at the time of admission and at 2, 12, 24, 48, and 72 h after the start of aminophylline infusions. Results : Nine patients out of 37 in the low-dose group and six of 21 in the usual-dose group dropped out because of uncontrolled irritability. The serum concentrations of theophylline in dropouts ($3.68{\pm}1.93$ ig/mL) and participants ($4.47{\pm}2.45$ ig/mL) were not significantly different. Irritability was a more frequent side effect in the usual-dose group at 12 h, but there was no difference between the low-dose and usual-dose groups in terms of vomiting, sleep disturbance, and jitter. Most of the severe adverse effects were observed in children below two years of age. Conclusion : Some patients dropped out regardless of the initiating aminophylline dose, especially patients under the age of two years.

Traumatic dental injuries in childhood and adolescent occurred more frequently than in adult. The time between the accident and the treatment is one of the most critical factors to prognosis, and because of the limited time available to examine and treat patients with traumatic dental injuries, if not treat appropriately, the result would be critical for the patient. In the previous studies, the prevalence and incidence of traumatic injuries were the most frequent at the age of 8 to 10 years, the majority of dental injuries involve the anterior teeth, especially the maxillary incisors, and males were more prevalent than females in an approximated proportion of 2:1. As the mean age of complete root formation is 10 years old, the maxillary permanent incisor involved in the most affected age group is usually immature, and the possibility of pulpal healing through excellent revascularization exists, more positive prognosis for pulp vitality would be expected. These are treatment cases of the immature maxillary permanent central incisor involved in the traumatic injury, and reports for progress and results of preserving the pulp vitality through the conservative treatment instead of the conventional endodontic root therapy.

The survival rate of children with cancer has increased significantly from less than 30% in 1960s to 75% during the recent years with the development of modern medical technologies. As a result, the cancer of children today is no longer classified as incurable diseases. Rather, it is recognized as a chronic illness. However, children with cancer are still suffering from physical and psychosocial ailments caused by long-term hospitalization. In particular, teenagers are more likely to be affected by these problems because of interests on one's appearance and peer relationships This study investigated the relationship of the level of body distortion and disease adjustment of children with cancer, and how demographic factors, disease factors, and the level of body distortion affect disease adjustment. Data were collected between October 22, 2007 and November 16, 2007 and the total respondents consisted of 82 children, ages 10 to 18. SPSS 12.0 with descriptive statistics, t-test, correlation and multiple regression were used for data analysis. The results showed that the factors which influence the disease adjustment of children with cancer were age, school enrollment, and the level of body distortion. The result of this study has major implications for the government to provide support for children with cancer to stay in school. Additionally, programs that assist children to build positive body images need to be developed in accordance with their ages and psychosocial characteristics.

Purpose : To evaluate the clinical features and characteristics of childhood periodic syndromes (CPS) in Korea using the new criteria of the International Classification of Headache Disorders (ICHD)-II. Methods : The study was conducted at pediatric neurology clinics of five urban tertiary-care medical centers in Korea from January 2006 to December 2007. Patients (44 consecutive children and adolescents) were divided into three groups (cyclic vomiting syndrome [CVS], abdominal migraine [AM], and benign paroxysmal vertigo of childhood [BPVC]) by recurrent paroxysmal episodes of vomiting, abdominal pain, dizziness, and/or vertigo using the ICHD-II criteria and their characteristics were compared. Results : Totally, 16 boys (36.4%) and 28 girls (63.6%) were examined (aged 4-18 yr), with 20 CVS (45.5%), 8 AM (18.2%), and 16 BPVC (36.4%) patients. The mean age at symptom onset was $6.3{\pm}3.6$ yr, $8.5{\pm}2.7$ yr, and $8.5{\pm}2.9$ yr in the CVS, AM, and BPVC groups, respectively, showing that symptoms appeared earliest in the CVS group. The mean age at diagnosis was $8.0{\pm}3.4$ yr, $10.5{\pm}2.6$ yr, and $10.1{\pm}3.2$ yr the CVS, AM, and BPVC groups, respectively. Of the 44 patients, 17 (38.6%) had a history of recurrent headaches and 11 (25.0%) showed typical symptoms of migraine headache, with 5 CVS (25.0%), 2 AM (25.0%), and 4 BPVC (25.0%) patients. Family history of migraine was found in 9 patients (20.4%): 4 in the CVS group (20.0%), 2 in the AM group (25.0%), and 3 in the BPVC group (18.8%). Conclusion : The significant time lag between the age at symptom onset and final diagnosis possibly indicates poor knowledge of CPS among pediatric practitioners, especially in Korea. A high index of suspicion may be the first step toward caring for these patients. Furthermore, a population-based longitudinal study is necessary to determine the incidence and natural course of these syndromes.

Purpose : To investigate the feature of the range of measles in 2000, we studied epidemics of the measles in western Kyungnam District. Methods : Among 489 patients under 15 years of age who visited or were admitted to in our hospital from January to December in 2000, we selected 344 patients whose measles IgM antibody was positive. We investigated age, monthly incidence, clinical features, vaccination history, and measles IgG antibody. Results : Patients under 12 months of age occupied the largest proportion(36.9%). Patients firstly occurred in May and geometrically increased from October. Fever, cough and rashes were observed in all patients but conjunctivitis in 54.9%, Koplik spot in 23.8%. The first vaccination ratio was 41.8%. Compared with the number of patients and the first vaccination ratio, the first vaccination ratio was the lowest under 12 months of age. After that age group, the number of patients was decreased as the first vaccination ratio was increased. Among 152 patients sampled for measles IgG antibody, 35 patients had received the first vaccination and 6 patients had received the second vaccination. Among 35 patients who received the first vaccination, 22(62.9%) patients were negative of measles IgG antibody. Among 6 patients who received the second vaccination, 3(50%) patients were negative. Conclusions : Measles patients under 12 months still dominated. Therefore, routine vaccination of single measles vaccine, is currently done at 6 month when measles are prevalent, should be considered. High first vaccination failure suggests problems of vaccines itself, transport and storage rather than vaccination methods. Therefore a thorough investigation should be made.

Purpose : We aimed to examine the effect of rooming-in care on newborn infants emotional stability by comparing them with those cared for in a nursery. Methods : Forty-eight full-term newborn infants born at Cheil General Hospital between July 1 and October 31, 2007, were enrolled. Twenty-four newborn infants were roomed-in in their mothers rooms (rooming-in group), and 24 newborns were cared for in the hospital nursery (the nursery group) for the first 3 days of their lives. Those with perinatal problems that required medical treatment were excluded. By using Brazeltons neonatal behavior assessment scale, we measured irritability and self-quieting as well as the duration of crying after heel-stick puncture for the newborn metabolic screening test. Results : The rooming-in group had a higher irritability score than the nursery group ($6.8{\pm}1.7$ vs. $4.2{\pm}2.1$, P<0.001), thereby suggesting stable behavior against external irritation; the former also had a higher self-quieting activity score ($5.9{\pm}0.3$ vs. $4.5{\pm}1.8$, P=0.001), thereby suggesting that stability was reached quickly from the irritated state. Time taken to stop crying after the heel-stick puncture was significantly shorter in the rooming-in group than in the nursery group ($17{\pm}15.1$ seconds vs. $115.3{\pm}98.5$ seconds, P<0.001). Conclusion : These results show that newborn infants in the rooming-in group exhibit more stable behavior against external irritation and can be stabilized from an irritated state more quickly than infants cared for in the nursery, even after a few days of rooming-in care.

Authors surveyed intrafamilial child sexual abuse in the children under 15years old in clinical. We sent the semi-structured child sexual abuse questionnaires to 7055 board certified pediatrics, obstetrics and gynecology, family medicine and emergency medicine. Total respondents were 1205. The results from these respondents were as follows. 1) The numbers of respondents who have had the experience of treating victims of intrafamilial child sexual abuses were 157(13.0% of total respondents). 2) Among the perpetrators, 58(36.9%) were siblings and 32(20.4%) 26(16.6%) were step-fathers, and respectively. The most common age bracket was 10s(39.5%), and the next was 40s and 50s (33.7%) Almost all(98.7%) of the perpetrators were male. 3) The mean age of victims was $12.1{\pm}3.3$ years old, and all of the victims were female, and the number of victims who had previous mental or physical handicaps and behavior problems were 5(3.2%) and 8(5.1%) respectively. 4) The ways by which intrafamilial child sexual abuses were found were abnormal behaviors 45(28.7%), victim's own report 40(25.5%), pregnancy 18(11.5%), pain complaint 13(8.3%), other person's report 13(8.3%), and detection during examination 12(7.6%). 5) Time lags between intrafamilial child sexual abuses and hospital visits were after 1 month 97(61.8%), from 1 day to 1 week 29(18.5%), within 1 day 21(13.4%), and from 1 week to 1 month 10(6.4%). 6) Physical complications were perineal wound 93(59.2%), hymen rupture 90(57.3%), pregnancy 68(43.3%), wound of other part of body 11(7.0%), and sexually transmitted disease 4(4.5%). 7) Treatment for victims were discharge 92(58.6%), admission, operation or transfer to a bigger hospital 25(15.9%), psychiatry consult 19(12.1%), report to police(10.9%) and social work consult 3(1.9%). These results suggest that considerable numbers of physicians have had the experience of treating victims of intrafamilial child sexual abuses, and intrafamilial child sexual abuses are the major medical as well as social issue in children in Korea.
