PURPOSE: We diagnosed pediatric functional gastrointestinal disorders in Korean children and adolescents using Rome III criteria and investigated the clinical validity of QPGS-Rome III. METHODS: Diagnosis based on QPGS was compared with the physician's diagnosis based on Rome III criteria. One hundred and thirty eight children and their parents completed the QPGS. Agreement rates were measured using Kappa method. RESULTS: In physician's diagnoses, the most prevalent disorders were functional dyspepsia (39.1%), irritable bowel syndrome (38.4%), and functional abdominal pain (18.8%). Among QPGS based diagnoses, the most prevalent disorders were irritable bowel syndrome (39.1%), functional dyspepsia (29.7%), and functional abdominal pain (21.7%). The agreement rate was substantial (kappa=0.72, p=0.00). Diagnostic disagreements probably resulted from different patient responses to bowel movement form and bowel frequency. CONCLUSION: Functional dyspepsia, irritable bowel syndrome, and functional abdominal pain were the most common disorders by Rome III criteria in the Korean pediatric and adolescent patients. The agreement rate between physician's diagnoses and QPGS based diagnoses supported the validity of the QPGS-Rome III in Korean pediatric and adolescent patients. QPGS seems to be useful in diagnosis of patients with functional gastrointestinal disorders by Rome III criteria.

We report clinical, cytogenetic, and fluorescence in situ hybridization (FISH) studies of a patient with ring chromosome 9. She presented with failure to thrive, facial dysmorphysm and mild psychomotor development delay in the absence of major malformations. Peripheral blood karyotype of the patient was 46,XX,r(9)(p24q34). G-band analysis suggested no loss of material in the ring chromosomes. FISH analysis using the subtelomere-specific sequences on chromosome 9p and 9q, revealed 46,XX,r(9)(p24q34),ish r(9)(D9S913-,D9S325+). Failure to detect any hybridization of a probe for the subtelomeric sequences in the ring 9p terminal suggested that this ring arose from breakage in the distal short arm. The cytogenetic and FISH data in our case provided further evidence for the existence of a "complete ring" phenotype with incomplete subtelomeric sequences.

PURPOSE: Childhood obesity can be complicated by hypertension, hyperlipidemia, non-alcoholic fatty liver disease, and diabetes mellitus. The aim of this study was to evaluate the prevalence of obesity and metabolic complications of children and adolescents based on the degree of obesity. METHODS: We analyzed the records of 8,880 students who received student health examinations between May 2006 and October 2008 at the Eulji General Hospital. The prevalence of obesity was evaluated by the body mass index and obesity index. A total of 1,076 obese students had blood tests. We analyzed aspartate aminotransferase (AST), alanine aminotransferase (ALT), fasting glucose, total cholesterol, and blood pressure according to the degree of obesity. RESULTS: According to the body mass index, the overall prevalence of obesity was 7.2% (7.8% of male and 6.5% of female students). Based on the obesity index, 12.3% of students (mild: 6.3%, moderate: 5.0%, and severe: 1.0%) were obese. The prevalence of hypercholesterolemia, ALT elevation, and hypertension were increased as a function of the degree of obesity (p<0.05), but hyperglycemia showed no significant differences (p=0.298). The overall prevalence of ALT elevation was 17.7% (mild obese group, 10.4%; moderate obese group, 20.5%; and severe obese group, 46.8%). The prevalence of hypercholesterolemia, hypertension, and hyperglycemia were significantly higher in the elevated ALT group (24.7%, 42.6%, and 5.2%, respectively) compared to the normal ALT group (11.1%, 29.8%, and 2.0%, respectively; p<0.05). CONCLUSION: Hypercholesterolemia, liver function test abnormalities, and hypertension were associated with the degree of obesity. We should focus our attention on managing obese children and adolescents to prevent metabolic complications.
