PURPOSE:The prevalence of childhood obesity has been increased rapidly, associated with high morbidity of dyslipidemia, cardiovascular risk factors and insulin resistance/hyperinsulinemia. Hyperinsulinemia in obese children may depend on either increased insulin secretion or decreased insulin clearance. We investigate whether insulin secretion and clearance are different between obese and normal weight children. METHODS:The body mass index(BMI), fasting serum glucose, insulin and C-peptide levels were measured in 101 children(52 obese children and 49 non-obese controls) in Ansan area, from 6 to 14 years old. Fasting serum C-peptide/insulin ratio, insulin/glucose ratio, homeostasis model assessment(HOMA) were calculated and compared between obese and control group. RESULTS:The fasting serum insulin and C-peptide levels were significantly higher in obese group than in controls. The C-peptide/insulin ratio was significantly lower and insulin/glucose ratio was significantly higher in obese group than in controls. There were positive correlations between BMI and fasting serum insulin level, fasting insulin/glucose ratio and HOMA. The prevalence of hyperinsulinemia is higher in obese adolescents than in controls. CONCLUSION: Our findings suggest that increased insulin secretion and decreased insulin clearance may contribute to hyperinsulinemia in obese children.

We present a rare case of abdominal compartment syndrome due to a bulimic attack in a 19-year-old female patient with bulimia nervosa. She was admitted to our emergency room with complaints of progressive abdominal pain following bulimia. Computed tomography showed dilated stomach with food and air pressed other visceral organs and major abdominal vessels. Decompression using nasogastric tube or gastric lavage tube failed. At laparotomy, we performed gastrotomy and decompression was performed. After decompression, she fell into hypovolemic shock due to bleeding in the intra-gastric and peritoneal cavity. Twelve hours after the operation, the patient died due to refractory hypovolemic shock from uncontrolled bleeding following decompression of abdominal compartment. It should keep in mind that binge-eating habits in patients with bulimic nervosa could cause abdominal compartment syndrome due to gastric distension and this may be a potentially fatal condition.

Carbon dioxide is a colorless, odorless, nonirritating gas with many practical uses. In particular, because it can displace oxygen from the environment, it is used as a fire extinguisher. We describe an incident that occurred as a result of malfunction of a carbon dioxide-based fire extinguishing system in our hospital. Twelve casualties reached our emergency department. Symptoms of exposure included nausea, dizziness, loss of consciousness, vomiting, chest discomfort, and seizure. Results of initial arterial blood gas analysis showed acidosis in five patients. A new pneumonic infiltration at the left. upper lung field was observed in one patient, while sinus tachycardia in electrocardiography (ECG) was observed in another patient. Oxygen was initially supplied to all casualties, until symptoms of intoxication had disappeared. Three patients were admitted to the hospital, but were discharged without complication. Despite occurrence of massive casualties, with significant symptoms due to unintentional exposure to high concentrations of carbon dioxide, patients' symptoms were relieved by supportive care.

Eosinophilic cystitis is an uncommon inflammatory process seen in children and adult which was recognized in 1960. The disease is similar to interstitial cystitis. tuberculosis and bladder neoplasms in the clinical manifestations and should be differentiated from them. We herein report a case of eosinophilic cystitis in a 60-year-old woman which was confused. with bladder carcinoma with brief review of the literatures.

PURPOSE: Ghrelin, being secreted from the stomach, stimulates growth hormone secretion and controls energy homeostasis by increasing appetite. Leptin, being secreted from the adipocytes, controls weight and energy homeostasis by decreasing appetite. Leptin concentration is reported to increase after childhood cancer therapy. This study was aimed to compare ghrelin and leptin concentrations in normal children and children who received cancer therapy. METHODS: We enrolled forty-three patients who were diagnosed with cancer and received radiotherapy or chemotherapy during Dec. 2004 through Dec. 2005 in St. Marys hospital and Kangnam St. Marys hospital. Forty-five healthy children were selected as a control group whose age, gender, weight and height were similar to those of cancer group. The serum leptin and ghrelin concentrations were also measured by radioimmunoassay. RESULTS: The cancer group showed higher BMI and leptin concentrations. The control group showed higher concentrations of ghrelin. Both control and cancer groups revealed positive correlations between leptin concentrations and BMI. Ghrelin concentrations in the control group showed negative correlations with age, height, weight and BMI but no significant correlation was found in the cancer group. All the parameters in the group treated with chemotherapy only were not different from those in the group treated with chemotherapy and irradiation. But the level of ghrelin in the acute myeloid leukemia group was much higher than those in the acute lymphoblastic leukemia group. CONCLUSION: Patients with pediatric cancer treatment have presented higher BMI and leptin concentrations but lower ghrelin concentrations than those in healthy children. Because of the relatively short duration and cross sectional method of the study, however, further long term and prospective study will be required in the future.

PURPOSE: Ghrelin stimulates the secretion of growth hormone and other pituitary hormones, and has orexigenic effects. It may have a physiologic role in fetal and neonatal growth. Leptin secreted by the adipocytes reflects fat mass in infants as well as adults. The aim of this study was to evaluate the relation of cord blood ghrelin and leptin levels to body weight(BW), body mass index(BMI), insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding protein-3(IGFBP-3) levels in appropriate for gestational age(AGA) newborns. METHODS: Sixty healthy AGA newborns(31 males and 29 females, gestational age[GA] 34-42 weeks) were included in this study, whose BW and BMI were measured at delivery. Umbilical cord venous blood samples were withdrawn, and ghrelin and leptin were measured by radioimmunoassay. Cord blood IGF-I and IGFBP-3 were determined by immunoradiometric assay. RESULTS: The mean levels of ghrelin were inversely correlated with BW(r=-0.29, P<0.05) and GA (r=-0.28, P<0.05), but were not affected by gender. The mean levels of leptin levels showed positive correlation with BW(r=0.44, P<0.01), GA(r=0.36, P<0.01), and BMI(r=0.28, P<0.05). The leptin levels of females were higher than those of males. There was no gender difference in leptin levels in neonates under GA 37 weeks. However, the leptin levels of females were higher than those of males (P<0.01) in newborns with GA 37 weeks or over. There was no correlation between ghrelin and leptin levels. Ghrelin and leptin levels showed no relations to cord blood IGF-I and IGFBP-3 levels. CONCLUSION: These data suggest that cord blood ghrelin may have an inverse correlation with BW in AGA newborns, and leptin levels are positively correlated with BW and fat mass. Further study of ghrelin concentrations in cord blood is necessary to elucidate the physiological and pathological roles of ghrelin during the fetal and neonatal periods.

Neospora caninum is an important cause of abortion in cattle, and dogs are its only known definitive host. Its seroprevalence among domestic urban and rural dogs and feral raccoon dogs (Nyctereutes procyonoides koreensis) in Korea was studied by indirect fluorescent antibody test (IFAT) and by the neospora agglutination test (NAT), respectively. Antibodies to N. caninum were found in 8.3% of urban dogs and in 21.6% of dogs at dairy farms. Antibody titers ranged from 1: 50 to 1: 400. Antibodies to N. caninum were found in six (23%) of 26 raccoon dogs. However, the potential role of raccoon dogs as a source of horizontal transmission of bovine neosporosis needs further investigation. The results of this study suggest that there is a close relationship between N. caninum infection among dairy farm dogs and cattle in Korea. This study reports for the first time upon the seroprevalence of N. caninum infection in raccoon dogs in Korea.

A 38-year-old woman was admitted to our hospital due to agitation, nausea, chest discomfort, tachycardia and hypertension 6h after ingesting approximately 60 capsules of sibutramine. The woman developed the clinical features of acute psychosis, including auditory hallucination, agitation and paranoid ideation, on day 2. No relevant changes were detected on the laboratory examinations or on the electrocardiogram throughout the period of hospitalization. She was treated with risperidone and benzodiazepine. The symptoms subsequently resolved completely with cessation of the provoking agent. The patient was discharged on day 7 and the follow-up revealed no sequelae for 5 months.
