Cystic lesions of the stomach are rare and usually detected incidentally during surgery or autopsy. Amongseven cases of cystic masses, duplication cysts accounted for four, retension cysts of ectopic pancreas for two,and cystic lymphangioma remaining one. In the upper gastrointestinal series, all were submucosally, whileendoscopic ultrasonography showed that the location of cystic masses was also submucosal. Except for two cases ofduplication cyst and cystic lymphangioma which were thin-walled, lesions were well-defined and showed lowattenuation. In addition, abdominal CT scanning showed two cases of retension cyst of ectopic pancreas.

BACKGROUND/AIMS: Noncardiac chest pain (NCCP) is a very common disorder world-wide and gastroesophageal reflux disease (GERD) is known to be the most common cause. The prevalence of NCCP may tend to decrease with increasing age. However, there is little report about young aged NCCP. The aim of this study was to examine the prevalence of GERD and to evaluate the efficacy of proton pump inhibitor (PPI) test in the young NCCP patients. METHODS: Thirty patients with at least weekly NCCP less than 40 years were enrolled. The baseline symptoms were assessed using a daily symptom diary for 14 days. Esophago-gastro-duodenoscopy (EGD) and 24 hr esophageal pH monitoring were performed for the diagnosis of GERD and esophageal manometry was done. Then, patients were tried with lansoprazole 30 mg twice daily for 14 days, considering positive if a symptom score improved > or = 50% compared to the baseline. RESULTS: Nine (30%) of the patients were diagnosed with GERD at EGD and/or 24 hr esophageal pH monitoring, also, 3 (10%) were diagnosed with GERD-associated esophageal motility disorder and 3 (10%) were non GERD-associated. Concerning PPI test, GERD-related NCCP had a higher positive PPI test (n = 8, 89%) than non GERD-related NCCP (n = 5, 24%) (p = 0.002). CONCLUSIONS: In young patients with NCCP, a prevalence of GERD diagnosed using EGD and/or 24 hr esophageal pH monitoring was 30%. PPI test was very predictable on diagnosis of GERD-related NCCP, thus, PPI test in young NCCP patients may assist to the physician's clinical judgment of NCCP.

Colonic lipomas represent mesenchymal origin tumors that are second most common benign colonic tumor after hyperplastic polyps and adenomatous polyps. The patho-genesis of them is not clear. Most patients are asymptomatic and the lesion is often detected incidentally at colonoscopy, operation, and autopsy. According to the size and the location of lipoma, it may cause intestinal obstruction, perforation, intussusception, and life-threatening bleeding. There have been many reports of small colonic lipomas removed by endoscopic resection. Giant lipoma which is greater than 2 cm in size has been associated with higher risk of perforation, thus it has been removed by surgery until now. We report a case of colonic giant lipoma inducing intussusception which could be removed by endoscopic resection.

OBJECTIVE: Helicobacter pylori(H. pylori) infection plays an importanat role in the pathophysiology of gastrointestinal diseases, and its diagnosis is crucial in clinical practice. Currently many diagnostic methods are introduced for its simple, and accurate diagnosis. 13C urea breath test(13C-UBT) is a convenient, non-invasive and reliable test for the diagnosis of H. pylori infection. To assess the clinical value of the 13C-UBT, we examined the sensitivity, specificity of 13C-UBT with regard to other tests. METHODS: A prospective multicenter study was done in 107 subjects(mean age 36 years, 55 males, 52 females) presenting for endoscopy from three university hospitals. We tested for H. pylori infection by 13C-UBT, serum IgG antibody level, and multiple biopsies for rapid urease testing and histology. Either a positive histology result or a combined positive CLO test and IgG ELISA in the presence of a negative histology results, was interpreted as a positive finding for H. pylori infection. 13C-UBT was performed after 4hrs fast. Breath samples were collected at 0 and 30 minutes after giving 75mg 13C-urea. RESULTS: Results were analysed by isotope ratio mass spectrometry and expressed as units of delta( 13C, 13CO2 /12CO2) and considered as positive for H. pylori if delta value was greater than 4.0. Sensitivity and specificity of 13C-UBT were 94.5%, and 100% respectively. No significant adverse events were noted. CONCLUSIONS: The 13C-UBT offers an easy, safe and accurate approach to the diagnosis of H. pylori infection in routine clinical practice

PURPOSE: Acute lymphoblastic leukemia (ALL) accounts for approximately 75% of all cases of childhood leukemia. We investigated epidemiology, clinical and laboratory features and treatment outcome of the children with ALL in Korea during recent 5 years. METHODS: One thousand forty nine patients were enrolled between January 1994 and December 1998 from 37 major hospitals in Korea. The data regarding the clinical and laboratory features including age, WBC counts at diagnosis, immunophenotype, morphology, cytogenetics and treatment outcome of patients were analyzed retrospectively by review of patient's medical records. Kaplan-Meier survival curves were constructed. The differences between groups analyzed by log-rank test. RESULTS: There were 597 males and 452 females. The distribution between the age 2 and 5 years is most common in 46.1%. The annual incidence rate per 100,000 population varied from 1.6 to 2.2. The 5 year event free survival (EFS) rates according to good prognostic factors were as follows: 67% bet ween 1-9 year of age at diagnosis, 69% in under 10,000/mm3of initial WBC count, 74% in early pre-B cell CALLA ( ) immunophenotype, 65% in L3 morphology, 68% in no CNS invasion. Most of patients were treated by CCG treatment protocol. The 5 year EFS was 63%. Main complications were sepsis (21.8%) and hemorrhage (12.5%). The relapse rate was 15.6%. The common causes of death were sepsis, DIC, pneumonia, relapse. CONCLUSION: Our results could provide the most recent and important information about acute lymphoblastic leukemia of children in Korea.
