PURPOSE: The role of plain, abdominal radiography in childhood constipation has not been fully evaluated. The aim of this study was to determine the accuracy and reliability of scoring systems assessing a fecal load on plain, abdominal radiographs in children with functional constipation. METHODS: Plain, abdominal radiographs from 38 constipated children and 39 control children were examined by four independent inspectors, pediatric residents. Four inspectors independently scored the radiographs according to three different scoring systems Barr, Blethyn, and Leech. No clinical information about the patients was available to the inspectors. Each abdominal radiograph was evaluated on two separate occasions, one week apart. Kappa coefficients were calculated as indicators of inter-and intra-inspector variability, coefficients < 0.20, 0.21~0.40, 0.40~0.60, 0.60, 0.61~0.80 and 0.81~1.00 were considered to indicate poor, fair, moderate, good, and very good agreement, respectively. RESULTS: The Leech score showed the highest reproducibility: the inter-inspector agreement was uniformly very good on two separate occasions (kappa values of 0.88, 0.91, 0.92, 0.86 in the first time and 0.81, 0.88, 0.89, 0.84 in the second time). Agreement using the Barr score was good (kappa values of 0.66, 0.67, 0.69, 0.66 in the first time and 0.68, 0.65, 0.71, 0.68 in the second time). However, agreement for the Blethyn score was the lowest of the three scoring systems. The Leech scoring system had the highest sensitivity and specificity compared to the Barr scoring system for the diagnosis of functional constipation by plain, abdominal radiographs. CONCLUSION: The Leech score appeared to be a more accurate and reliable method because of its high sensitivity and specificity for evaluating the fecal load on plain, abdominal radiographs in children with functional constipation. Therefore, the Leech scoring system was found to be the most useful for assessment for the degree of constipation on plain, abdominal radiographs in children.

Gilbert syndrome is the most common inherited disorder of bilirubin glucuronidation. It is characterized by intermittent episodes of jaundice in the absence of hepatocellular disease or hemolysis. Hereditary spherocytosis is the most common inherited hemolytic anemia and is characterized by spherical, osmotically fragile erythrocytes that are selectively trapped by the spleen. The patients have variable degrees of anemia, jaundice, and splenomegaly. Hereditary spherocytosis usually leads to mild-to-moderate elevation of serum bilirubin levels. Severe hyperbilirubinemia compared with the degree of hemolysis should be lead to suspicion of additional clinical conditions such as Gilbert syndrome or thalassemia. We present the case of a 12-year-old boy with extreme jaundice and nausea. The diagnosis of hereditary spherocytosis was confirmed by osmotic fragility test results and that of Gilbert syndrome by genetic analysis findings.

PURPOSE: The aim of this study was to determine how much acid exposure would occur in the proximal esophagus, both in normal and in patients with abnormal distal esophageal acid exposure. METHODS: Fourty-six patients with suspected GER were classified into two groups, 24 patients with pathological distal reflux (group II); 22 patients with normal distal reflux(group II). The ambulatory dual-probe esophageal pH monitoring was performed for 18-24hr. The abnormal reflux was defined when the percent of time that pH was below 4.0 exceeded the 95th percentile of normal value. RESULTS: The siginficant differences between distal and proximal esophageal pH recordings in group I persisted for all parameters except for the longest episode, but didn't persist in group II. At the distal esophageal site, the median percent time with pH<4.0 in group I was 19.3 and significantly higher than at proximal site. Half of patients with pathological distal reflux also had proximal acid reflux. Correlation coefficients between the distal and proximal esophageal sites in group I of the number of reflux episodes and time of the longest episode were 0.451 and 0.646 respectively. CONCLUSION: The 50 percent of patients with pathological distal acid reflux also had abnormal acid exposure in the proximal esophageal site. Therefore, we recommand simultaneous pH recordings from dual probe esophageal sites in children with gastroesophageal reflux.

PURPOSE: The purpose of this study was to find an objective criteria to determine the position of normal anus in Korean children and to evaluate the clinical significance of anterior displacement of anus in children with constipation. METHODS: Three hundred and thirty-nine normal children and 24 children with idiopathic constipation represented the basis of this study. The position of the normal anus was defined by the anogenital index, which is the distance from the anus to the vagina or scrotum divided by the distance between the vagina or scrotum and coccyx. RESULTS: The mean anogenital index were 0.54 +/- 0.08 in normal male children, and 0.52 +/- 0.04 in male with constipation (P>0.05). The mean anogenital index were 0.43 +/- 0.08 in normal female children, and 0.42 +/- 0.07 in female with constipation (P>0.05). The anogenital index was very constant by age except for late male childhood. The anogenital index in female was significantly lower than in the male (P<0.001). There was no significant difference of the anogenital index between the normal and constipated groups. In both male and female groups with constipation, the anogenital index did not deviate from the mean, but one female patient had an anogenital index of 0.29. The ratio of the anterior displacement of the anus was 21 out of 339 (6.2%) in the normal group (SD<0.05), and 2 out of 24 (9%) in the constipated group (SD<0.05), and there was no difference (P>0.05). CONCLUSION: The anogenital index is an objective criteria to define the position of normal anus or anterior displacement of anus. There is no correlation between anterior displacement of the anus and idiopathic constipation.

Prevalence of obesity in Korean children and adolescents has dramatically increased since the last 10-20 years. It is important to initiate prevention efforts early in childhood because prevalence of obesity in adolescence is the strongest predictor of its prevalence in adulthood. Intrauterine life, infancy, and preschool years may comprise the critical periods that are essential for the long-term regulation of energy balance therefore, obesity-prevention strategies should be initiated in utero and continued throughout childhood and adolescence. Families with high-risk children should be provided early education about maintaining normal weight. Encouraging physical activity and, especially, avoiding inactivity, are key challenges in the prevention of future obesity. Schools should be primarily involved in educating parents to discourage their children from excessively watching TV or playing computer games and eating unhealthy snacks and food. The involvement of medical practitioners is also important, especially, in the case of obese parents, obesity prevention strategies should be promoted from the first visit of pregnant women to the physicians. Health professionals can also be involved in obesity prevention because they are ideally equipped to identify young children at risk of obesity. Community and nation-wide efforts to increase awareness and promote environments that encourage physical activity and healthy nutrition are required.

PURPOSE: The aim of this study was to determine clinical significance of dual-probe esophageal pH monitoring and to compare four pH monitoring parameters between proximal and distal esophagus in pathological gastroesophageal reflux disease with recurrent respiratory symptoms. METHODS: Among the thirty-four patients who were performed 24 hr pH monitoring, seventeen patients with pathological distal reflux were classified into two groups: Group I (n:12) had recurrent respiratory symptoms and Group II (n:5) hadn't recurrent respiratory symptoms. The ambulatory dual-probe esophageal pH monitoring was performed for 18~24 hr. A pathologic GER was defined when reflux index (percent of the investigation time a pH<4) exceeded the 95th percentile of normal value. RESULTS: Among the sixteen patients with recurrent respiratory symptoms, twelve patients (75%) have pathological distal reflux. Whereas among the eighteen patients without recurrent respiratory symptom, five patients (28%) have pathological distal reflux. In the Group I, the significant differences between proximal and distal esophageal pH recordings persisted for all parameters, but didn't persist in group II except for longest episode. Comparing esophageal pH four parameters between group I and group II at the proximal esophageal site, all parameters didn't show statistically significant differences. CONCLUSION: Regardless of respiratory symptoms, patients with pathological distal reflux didn't show statistically significant differences in the all parameters at the proximal esophageal site. Therefore we may reconsider usefulness of dual probe pH meter in patients with recurrent respiratory symptoms.
