PURPOSE: This study was aimed to investigate the psychiatric manifestations in children with epilepsy and the associations with seizure-related variables. METHODS: The Korean version of the Child Behavior Checklist (K-CBCL) and the ADHD Rating Scale (K-ARS) were used to assess the psychopathology of 78 children with epilepsy (39 boys, mean age: 9.8+/-3.26 years-old) and 78 healthy comparisons matched for age and sex. RESULTS: Compared with healthy comparisons, children with epilepsy showed differences in the social, school, total competence scale, withdrawn, somatic complaints, social problems, thought, attention problems, aggressive behavior, internalizing and externalizing problem, and total behavior problem scores in the K-CBCL. Significant differences in the social, school, total competence scale, withdrawn, social problems, attention, and total behavior problem scales were found between groups in clinical spectrum and nonclinical spectrum. The inattentive, hyperactive/impulsive, and total scores of the K-ARS between groups were significantly different. In addition, the total scores of the K-ARS between subjects in clinical spectrum and nonclinical spectrum were different. The more the number of antiepileptic drugs, the higher significance of the score for aggressive behavior, sex problem, somatic complaints in the K-CBCL, and the inattentive scales in the K-ARS. In addition, the withdrawn, anxious/depressed and somatic complaints in the K-CBCL were correlated with sex, onset age and seizure type, respectively. CONCLUSIONS: Children with epilepsy may experience more various and serious psychiatric problems than healthy children. Responsiveness to antiepileptic drugs and seizure itself can be risk factors of psychiatric manifestations in epileptic children.

PURPOSE: To study the effectiveness of chondrocyte and periosteum-derived cell transplantation in preventing bar formation in growth plate injuries. MATERIALS AND METHODS: Thirty immature rabbits were grouped according to site of growth plate damaged (distal femur or proximal tibia on the medial side) and type of cell and material inserted (chondrocytes plus agar, periosteum-derived cells plus agar, periosteum-derived cells plus Gelfoam, agar alone, or Gelfoam alone). Radiograms were taken for 16 weeks to measure the changes in varus angle of the distal femur and proximal tibia. Transformation of inserted cells was observed histologically. RESULTS: Rabbits inserted with agar alone showed more severe genu varum compared to those inserted with chondrocytes plus agar. Rabbits inserted with periosteum-derived cells plus agar or Gelfoam showed similar deformities compared to those inserted with agar or Gelfoam alone. Some inserted periosteum-derived cells began transformation into chondrocytes. All rabbits showed gradual bar formation and ultimate fusion of the growth plate. CONCLUSION: Cell-based therapy of growth plate injury still has obstacles to overcome. Further study will be required on how to maintain the inserted chondrocytes, or chondrocytes differentiated from the inserted periosteum-derived cells, and to prevent them from changing into osteoid formation cells.

OBJECTIVES: Delayed sleep phase syndrome (DSPS) is characterized by difficulties in falling asleep and waking up at a desired time. Dawn simulation is a technique using a light that gradually increases in intensity before awakening in the morning, to imitate a natural sunrise. It has been found to be effective in decreasing both morning drowsiness and difficulty in awakening as well as treating symptoms of seasonal affective disorder. The aim of this study was to determine whether dawn simulation is helpful in decreasing difficulty in morning awakening and daytime sleepiness in adolescents with DSPS. METHODS: Twelve adolescents with DSPS participated in a 2-week dawn simulation trial. Each subject self-assessed level of difficulty in awakening, morning drowsiness and daytime sleepiness during a 2-week baseline period and a following 2-week trial period with dawn simulator. Subjects used Stanford Sleepiness Scale (SSS) for measuring morning drowsiness and Epworth Sleepiness Scale (ESS) for measuring daytime sleepiness. Difficulty in awakening was assessed by a single-item questionnaire. RESULTS: Dawn simulation trial decreased morning drowsiness (p=0.016) and daytime sleepiness (p=0.013) significantly compared to baseline. It also seemed to improve difficulty in awakening, but the effect was not statistically significant (p=0.092). CONCLUSION: Dawn simulation may help waking up in the morning and may improve daytime functioning by deceasing both morning drowsiness and daytime sleepiness in adolescents with DSPS.

OBJECTIVE: To clarify the biological behavior and prognostic factors of brain stem gliomas, the authors reviewed 48 patients with brain stem gliomas treated between 1980 and 1996. PATIENTS AND METHOD: The clinical presentation, tumor location, pathology, and treatment modalities were correlated with the prognosis of these tumors. Male to female ratio was 1.1:1, with the median age of 12.5 years. Thirty patients(63%) were below 15 years old, and 18 patients(38%) were of adult ages. Mean follow up period was 21.8 months. RESULTS: Focal tumors were in 22 cases and diffuse tumors were in 26. All nine midbrain tumors were focal type. Twenty-two(92%) cases among 24 potine tumors were diffuse type and two cases were focal type as dorsally exophytic tumor. Eleven(73%) cases among 15 medullary and cervicomedullary tumors were focal type and four(27%) cases were diffuse type. Pathologically, there were 14 anaplastic astrocytomas, 11 low grade astrocytomas, 4 glioblastomas, 3 oligodendrogliomas, and 1 ganglioglioma. Fifteen tumors were diagnosed only radiologically without histologic verification. Surgery was done in 33 patients(gross total or subtotal removal in 8, biopsy or partial removal in 15, stereotactic biopsy in 10). Radiation therapy was given in 41 patients(conventional in 29, hyperfractionated in 12). Chemotherapy was done in four patients. CONCLUSION: Statistically significant prognostic factors were symptom duration prior to diagnosis(p=0.0004), cranial nerve palsy(p=0.0206), extent of tumor growth(p=0.0219), contrast enhancement(p=0.0226), intratumoral cyst(p=0.047), histopathological grading(p=0.0304), surgery in patients with focal tumors(p=0.0018), and radiation therapy(p=0.0149).

BACKGROUND/AIMS: Adefovir dipivoxil (adefovir) effectively inhibits both wild-type and lamivudine-resistant hepatitis B virus (HBV) replication. The development of adefovir resistance is both delayed and infrequent compared with lamivudine resistance. The aim of this study was to characterize the serologic, biochemical, and virologic response to adefovir, and to explore the factors affecting initial virologic response (IVR, defined as a decrease in serum HBV below 4 log10copies/mL after 6 month of treatment) and adefovir resistance in lamivudine resistant HBV-infected patients. METHODS: This study population comprised 76 patients with lamivudine-resistance who had received adefovir for more than 12 months between March 2004 and December 2006. The adefovir-resistant mutant was assayed at 6 months and 12 months during adefovir administration. Restriction-fragment mass polymorphism analysis was used for detecting YMDD and adefovir mutants. RESULTS: After adefovir administration, an IVR was observed in 31% of the patients with lamivudine resistance. Factors associated with an IVR were HBeAg negativity (P=0.04) and the presence of liver cirrhosis (P=0.04). Age, sex, pretreatment levels of alanine aminotransferase and aspartate aminotransferase, pretreatment HBV DNA levels, presence of precore mutation, and type of YMDD mutants were not related to an IVR during adefovir treatment. The prevalence of adefovir resistance was 5% and 13% at 6 months and 12 months after therapy, respectively. Mixed infection of the precore mutant was a risk factors for the emergence of adefovir resistance (P=0.01). CONCLUSIONS: Lamivudine-resistant HBV patients exhibiting HBeAg negativity and liver cirrhosis were more likely to achieve an IVR after adefovir therapy. Adefovir resistance was associated with mixed infection of the precore mutant.

PURPOSE: Children under 3 years old with medulloblastoma (MB) or supratentorial primitive neuroectodermal tumor (SPNET) have a poor prognosis. They are more susceptible to the deleterious effects of craniospinal radiation (CSR). This study was undertaken to determine the survival rates and prognostic factors of currently used treatment. METHPDS: Retrospective review of 19 children (MB 16, SPNET 3) who were newly diagnosed as MB or SPNET at Seoul National University Children's Hospital from April 1996 to August 2000 was done. Eligible Patients were treated with postoperative induction chemotherapy using Children's Cancer Group (CCG) 9921A or 9931. Patients over 3 year of age received CSR as well. RESULTS: Three Patients with SPNET are all alive without disease. However, 6 patients under 3 years old at diagnosis with MB were all dead whereas only one patient had an event among 10 patients over 3 years old at diagnosis. Among patients with MB, age under 3 years at diagnosis or residual tumors after induction chemotherapy correlated with poor outcome. Metastasis at diagnosis, postoperative residual disease or extent of excision did not have a significant effect on survival statistically. Three-year event-free survival (EFS) of patients with MB was 53%. Three-year EFS of patients over 3 years old at diagnosis with MB was 85.7% and 1-year EFS of under 3 years old at diagnosis with MB was 16.7%. CONCLUSION: The combined use of chemotherapy and CSR in the treatment of MB and SPNET improved survival in children over 3 years old, whereas any treatment failed to improve survival in children under 3 years old. So, there's a need for a new treatment modality to improve survival of children under 3 year of age.

BACKGROUND AND OBJECTIVES: A correlation between the BNP reduction ratio and prognosis could be expected to be found by evaluating the BNP reduction depending on the volume status during the early period. SUBJECTS AND METHODS: Between October 2002 and June 2004, 120 patients with acute heart failure (AHF)(<1 month) were included. The patients were divided into three groups according to their volume status, as follows. Group I: patients with clinical & radiological wet status, Group II: clinical dry & radiological wet status and Group III: clinical & radiological dry status. The blood BNP (Triage(r)) level and clinical parameters were analyzed. The bad prognostic parameters were defined as readmission due to heart failure, a major adverse cardiac event or cardiovascular death. RESULTS: The mean patient age was 68.0+/-12.7 years, and 50.0% of the subjects were male. The most frequent etiology of AHF was ischemic heart disease (35.8%). There were 61.7, 24.1 and 14.2% in Groups I, III and III, respectively. The baseline BNP level was higher in group I and II than in group III patients (I: 1540.4+/-1202.8, II: 1482.8+/-1281.6, III: 666.4+/-827.9 pg/mL, p=0.036) as was the early BNP reduction ratio (I: 69.8+/-27.1, II: 67.4+/-32.8, III: 1.3+/-144.9%, p=0.007). Sixteen (13.3%) patients had a poor prognosis. From a logistical analysis, the early BNP reduction ratio (p=0.004) and creatinine level (p=0.029) were significant predictors of the clinical outcomes. CONCLUSION: The early change in the BNP level varied depending on the degree of congestive status, and was also correlated with the level of clinical outcomes. Therefore, in our opinion, the early monitoring of the BNP level will provide significant clinical information in AHF patients.
