BACKGROUND/AIMS: Foreign body (FB) removal is a common indication of therapeutic endoscopy in children. The trend is becoming wider and more rational in application. The spectrum of upper gastrointestinal FB's in children during a recent 2 year period was reviewed in Taegu, Kyungbook Province in order to obtain a the consensus of recent trend of indications and techniques of endoscopic FB removal in children. METHODS: Esophagogastroscopy was performed on 78 children who had been referred to 3 University Hospitals in Taegu for FB ingestion from Oct. 1996 to Sep. 1998. RESULTS: Age between 1~2 year was the peak age group; 22 cases (28%). Male to female ratio was 1.9:1. Thirty four cases (44%) were in the esophagus, 44 cases (56%) in the stomach. The majority (49%) of the FB's were coins, 26 of 34 esophageal FB's and 12 of 44 gastric FB's. Others were 14 sharp/pointed objects, 12 big/long objects, 7 toxic objects, etc. In 67 children (86%) the FB was successfully removed and spontaneous passage through the pylorus was observed in 9 children. CONCLUSIONS: Endoscopic FB removal can be performed safely and effectively in children with minimal or no complications by an experienced endoscopist. Proper arrangement should be conducted with consideration to the property of FB's, expected complication, and the possibility of an emergency situation.

Prostatic carcinoma is the most commonly diagnosed cancer in the United States in men. Prostatic carcinoma in Korean men is uncommon and accounts for less than 1% of total cancer: however, the incidence of prostatic carcinoma is continuously increasing. Several clinicopathologic parameters including stage, Gleason score, and serum PSA level have been widely accepted as well established prognostic factors. To study the clinicopathologic features of prostatic carcinoma in Korean men, 58 cases of prostatic carcinoma, which were diagnosed on radical prostatectony specimens at Asan Medical Center from Jan. 1993 to June 1998 (1993; 3 cases, 1994; 3, 1995; 6, 1996; 12, 1997; 24, 1998; 10), were evaluated. The prostatic carcinomas were divided into three groups according to Gleason score. Tumors with Gleason score 6 or lower, 7, and 8 to 10 were categorized as low-grade, intermediate-grade and high-grade tumor, respectively. The overall mean age of the patients was 62.6 years (range, 4 6~76 years); mean age was 65.4, 62.8 and 61.1 in low, intermediate and high-grade tumor, respectively (p>0.05). The overall mean serum PSA level was 38.6 ng/ml (range, 0.3~276.0 ng/ml); mean serum PSA level was 17.0, 29.0 and 60.9 ng/ml in low, intermediate and high-grade tumor, respectively (p=0.002). The mean T stage was 2.3, 2.4 and 3.1 in low, intermediate and high-grade tumor (p=0.001). The percentage of positive resection margin was 33.3, 50.0 and 91.0 % in low, intermediate and high-grade tumor (p=0.001). The overall presence of prostatic intraepithelial neoplasia (PIN) was 79.3 %; percentage of the presence of PIN was 100, 79.2 and 68.2 % in low, intermediate and high-grade tumor (p>0.05). As reported in the literature, our results indicated that Gleason score was a good predictor of stage and prognosis. The higher Gleason score, the more cases were with positive surgical margins, advanced pathologic stage, and high serum PSA level (p<0.05).

Thirteen patients with visceroatrial situs abnormalities were evaluated by magnetic resonance(MR) imaging. Eleven patients were confirmed surgically. Two patitnts were diagnosed by MRI and cardiac catheterization. Right isomerism was found in seven patients, left isomerism in two, and situs inversus in four. For the determination of situs, we evaluated the morphology of atrial appendages and main bronchi, the relationship between abdominal aorta and inferior vena cava(IVC), and the status of upper abdominal viscera. The bilateral atrial morphology was differentiated in 8 of 12 patients. The bronchial situs was determined in 11 of 12 patients. Juxtaposition of abdominal aorta and IVC was found in 6 of 7 with right isomerism. IVC interruption with azygos continuation was found in all two with left isomerism. Incidentally three cases of short pancreas were found. MR imaging showed all structures relevant for the assessment of situs, thus obvrating the need for performing additional diagnostic procedures. MR imaging, therefore, is a valuable tool in the clinical management of patients who are suspected of having a situs abnormality.

OBJECTIVE: The aim was to assess the value of resistance index(RI) and pulsatility index(PI) to differentiate between benign and malignant ovarian tumors by color and pulsed Doppler ultrasound. METHODS: 129 ovarian tumors identified with ultrasound were referred for color and pulsed Doppler ultrasound evaluation to calculate the lowest RI and PI, and the corresponding histopathologic diagnosis was recorded. RESULTS: The intratumor artery waveforms were obtained in 37.1%(36 of 97) of benign tumors and in 91.0%(29 of 32) of the malignant group. RI and PI were lower in malignant tumors than in benign tumors(p<0.01). Also, there was a significant incremental decrease in both indices value from the benign tumor toward borderline malignancy(p<0.05) and to invasive ovarian cancer(p<0.01). But, there was no significant difference in both indices value according to the FIGO stage of ovarian malignancy. For RI cut-off value of 0.6, sensitivity and specificity were 89.7% and 91.7%; for PI cut-off value of 1.1, 86.2% and 91.7%. Therefore, the most accurate cut-off values of RI and PI were 0.6 and 1.1, respectively. CONCLUSION: RI and PI calculated by color and pulsed Doppler ultrasound can help in the diagnosis and selection of treatment plan of ovarian tumors, especially when the morphological finding of ovarian tumor is equivocal. And during the follow up of benign tumors, both indicies can give us the clue of malignant potential of benign tumors.

Purpose: Several definitions for severe obesity have been used, primarily the 99th percentile of the body mass index (BMI) and 120% of the 95th BMI percentile. This study aimed to establish a standardized definition for severe obesity in children and adolescents in Korea. Methods: The 99th BMI percentile line and 120% of the 95th BMI percentile line were constructed using 2017 Korean National Growth Charts. To compare these 2 cutoff points for severe obesity, we included 9,984 individuals (5,289 males and 4,695 females) aged 10–18 years with anthropometric data available from the Korean National Health and Nutrition Examination Survey 2007–2018. Results: Although 120% of the 95th percentile of BMI is widely used as a definition of severe obesity, the 99th percentile is almost identical to 110% of the 95th percentile in Korea, according to the latest national BMI growth chart for children and adolescents. The prevalence rates of high blood pressure, high triglycerides, low high-density lipoprotein cholesterol, and high alanine aminotransferase in the participants whose BMI was ≥120% of the 95th percentile were higher than in those whose BMI was ≥99th percentile (P<0.001). Conclusion A cutoff value for severe obesity of ≥120% of the 95th percentile is appropriate in children and adolescents in Korea. To provide follow-up care for severely obese children and adolescents, it is necessary to add a new line at 120% of the 95th percentile to the national BMI growth chart.

Among 7,500 patients whom we have performed gastrofiberoscopy from July 1979 to June 1,982, 226 cases of stomach cancer were diagnosed. The frequency was 3. 0%. The ratio of male to female was 2: 1, the peak incidence, 69 cases(30.5%) was in 5th decade. 1) The frequency of stomach cancer among the age were 0. 5% in 1st decade, 0.4% in 2nd decade, 1.2% in 3rd decade, 2.5% in 4th decade, 5.9% in 5th decade, 12.6% in 6th decade 16.8% in 7th decade.
