Dietary information was obtained by a questionnaire. Results: The prevalence of obesity was 9.9%. There was no significant difference between genders. The mean caloric intake was 1,781 kcal in boys and 1,640 kcal in girls. The prevalence of excessive calories was 33% in boys and 30% in girls. The prevalence of a total cholesterol ≥ 200 mg/dL was 8.4%, TG ≥ 130 mg/dL was 5.0%, LDL-cholesterol ≥ 130 mg/dL was 3.1%, and HDL-cholesterol <35 mg/dL was 4.4%.

The obesity group was compared to the control group: for triglycerides ≥ 130 mg/dL the odds ratio was 4.08; for LDL-cholesterol ≥ 130 mg the odds ratio was 2.85; for a TC/HDL-cholesterol ≥ 4.0 the odds ratio was 1.16.

However, additional treatment options are needed because more than 50% of hepatitis B patients are unresponsive to interferon. Although lamivudine is widely used to treat hepatitis B, there are few studies on the effect of lamivudine in hepatitis B patients unresponsive to interferon. Methods: Eight interferon unresponsive patients (6 males and 2 females) were treated with lamivudine (3 mg/kg/day, maximum 100 mg/day) from 6∼12 months after interferon treatment was discontinued among 33 children with chronic hepatitis B. They were treated with interferon (interferon α-2b, 10 MU/m or pegylated interferon 1.5μg/kg) for 6 months from January 2000 to December 2007 at the Pusan National University Hospital. The medical records were analyzed retrospectively. Results: The age at treatment with interferon and lamivudine was 4.9±3.1 and 6.1±3.2 years, respectively. The serum ALT level before treatment with interferon was 148.1±105.8 IU/L and the log HBV-DNA PCR mean value was 6.95±0.70 copies/mL. The serum ALT level after treatment with interferon was 143.1±90.4 IU/L and the log HBV-DNA mean PCR value was 6.46±2.08. HBeAg negativization occurred in 2 patients. For all patients, normalization of the serum ALT levels and HBeAg seroconversion (except 2 patients with HBeAg negativization) occurred at 7.4±2.1 and 7.9±2.1 months respectively after lamivudine treatment. The HBV-DNA PCR became negative in 7 patients (87.5%) at 2.4±2.8 months. Complete response was achieved in 7 patients and no recurrence was observed in 2 patients for 3 years after the completion of treatment. Five patients are still under treatment for a mean treatment duration of 24.4±9.1 months. In one patient, viral breakthrough occurred and the treatment was stopped.

Dysphagia and repeated aspiration are common findings despite normal sucking. We conducted this study to assess the clinical features of cricopharyngeal incoordination in newborns and infants. Methods: An analysis of the clinical data from 17 patients with cricopharyngeal incoordination who were admitted to the Department of Pediatrics, Pusan National University Hospital, between 2000 and 2006 was conducted retrospectively. The diagnosis of cricopharyngeal incoordination was established by the clinical characteristics and the videofluoroscopic swallowing studies. Results: The male to female ratio was 1:1.1 (males 8, females 9) the age range 1 to 60 days. The body weight of 11 patients (64.7%) was less than the 10 percentile at diagnosis. Six patients (35.3%) were born prematurely. The associated anomalies or diseases were chromosomal anomaly (2 cases), congenital heart disease (3 cases), and laryngomalacia, hypoxic brain damage or neonatal seizures (1 case each). The chief complaints of patients were recurrent aspiration pneumonia (10 cases), feeding difficulty (9 cases), dyspnea (4 cases), and chocking (4 cases). The severity of aspiration on the videoesophagogram or esophagogram was mild in 12 cases. The correlation between the severity of aspiration and the duration of tube feeding after the diagnosis was significant (p<0.05). Conclusion: Cricopharyngeal incoordination should be considered in the differential diagnosis of newborns and infants, without known risk factors associated with swallowing dysfunction, when they present with unexplained respiratory problems. Although the prognosis of cricopharyngeal incoordination is good, early diagnosis and tube feeding are recommended to prevent the complications associated with this disorder.

Although it is easily treated by non-operative reduction using barium, water or air, this treatment is very stressful for young patients and may cause bowel perforation, peritonitis and shock. In this study, we identified the risk factors associated with the failure of non-operative reduction, to identify a group of children that would benefit from the procedure and those who would not. Methods: We reviewed the medical records of patients with intussusception who were treated at the Korea University Medical Center Ansan hospital from March 1998 to July 2006. Three hundred fourteen children with intussusception were identified. Among them, non-operative reductions were performed in three hundred. Clinical and radiological variables were compared according to the failure or success of the non-operative reduction. Results: Non-operative reductions were successful in 243 (81%) and failed in 57 (19%). The group that had failed procedures had a younger age (12.3±17.2 months vs. 18.0±15.8 months, p=0.03), longer symptom duration before reduction (33.6±29.0 hr vs. 21.5±20.3 hr, p<0.01), more vomiting and lethargy (p<0.01), but less abdominal pain and irritability (p<0.01), compared with the group that had a successful procedure. Logistic regression analysis showed that the factors associated with the failure of non-operative reductions were a younger age, less than 6 months of age (odds ratio: 2.5, 95% confidence interval: 1.2∼ 5.2, p=0.01), duration of symptoms, longer than 24 hrs before reduction (odds ratio: 2.1, 95% confidence interval: 1.2∼4.2, p=0.03), bloody stool (odds ratio: 4.8, 95% confidence interval: 1.9∼12.2, p<0.01), lethargy (odds ratio: 3.4, 95% confidence interval: 1.1∼10.4, p=0.04), and abdominal pain or irritability (odds ratio: 0.2, 95% confidence interval: 0.1∼0.4, p<0.01).
