Benign tumors of the esophagus occur rarely as compared with the incidence of carcinomas. Among the benign tumors of the esophagus such as leiomyoma, lipoma, hemangioma, papilioma. polyp, cystetc. leiomyoma is the most common, although less than 10 percents of leiomyomas of the gastrointestinal tract are found in the esophagus. Most of leiomyomas of the esophagus present as solitary lesions but multiple tumors occur in about 4 percents of cases. Leiomyomas of the esophagus are diagnosed by thorough clinical evaluation, esophagogram and upper gastrofiberscopic examination but histological confirmation requires surgical or necropsy specimens. Occasionally gastrofiberscopic polypectomized specimens are used. We report one case of multiple leiomyomas of the esophagus located in between 25 cm and 40 cm distance from the incisor in a 38-year-old man who complained of vague substernal discomfort for about 10 years. Gastrofiberscopic polypectomized specimen was used for preoperative histological confirmation. The pathologic examination of the specimen showed leiomyoma of the esophagus.

Chronic atrophic gastritis is a result of chronic inflammation characterized by the replacement of oxyntic and antral gastric glandular structures by connective tissue or by glandular structures inappropriate for location such as metaplastic atrophy. Chronic atrophic gastritis is considered as one of the major risk factors for noncardiac gastric cancer or mucosa associated lymphoid tissue lymphoma. Since chronic inflammation is generally considered to be triggered by Helicobacter pylori infection, many studies have evaluated whether H. pylori eradication therapy could make histologic improvement or reversal. However, it is controversial whether eradication of H. pylori improves atrophy or metaplasia. There has been a lot of conflict, but many previous studies including meta-analyses tend to demonstrate that it is possible that gastric atrophy could be improved after H. pylori eradication in the corpus but not in the antrum. Also, intestinal metaplasia seems to be irreversible even after H. pylori eradication.

The purpose of this study was to identify dietary patterns among children and adolescents in Korea and to examine their associations with obesity and some blood profiles. One day food consumption data measured by 24-hour recalls on 2704 subjects aged 1 to 19 were used from 2001 Korea National Health and Nutrition Survey. The data of blood profiles available in the ages of 10 or older was also used. After categorizing each food consumed into 29 food or food groups, five dietary patterns were derived through a factor analysis and subjects were classified into three major dietary patterns via a cluster analysis using the factor scores. Three dietary patterns were identified as 'traditional diet' (25.6%), 'westernized-fast food' (6.2%), and 'mixed diet' (68.2%). The 'traditional diet' pattern had a higher percentage in boys. Both the 'traditional diet' and the 'westernized-fast food' had higher proportions of adolescents (12-19 y) than younger children, while the 'mixed diet' had a higher percentage of preschool children (1-5 y). Obesity rate analyzed within each age group showed no differences among 3 dietary pattern clusters. Blood pressure and all plasma profiles were not different among dietary patterns when adjusted with age and gender. Conclusively, children and adolescents in Korea had three distinct dietary patterns, which were associated with gender and age. These patterns could be useful to plan nutrition interventions for teenager health promotion.

PURPOSE: Cancer is a genetic disease caused by alterations in key regulators of cell growth and cell turnover. We investigated apoptotic cell death and cell proliferation in gastric adenomas and adenocarcinomas. MATERIALS AND METHODS: The TdT-mediated dUTP-biotin nick end labelling (TUNEL) method and immunohistochemistry for Ki-67 were performed, using paraffin-embedded tissues of 41 gastric adenomas and 100 gastric adenocarcinomas. These results were compared with histopathologic parameters. RESULTS: The Ki-67 labelling index was higher in adenocarcinomas than in adenomas and the apoptotic index was higher in adenomas than in adenocarcinomas. There were no significant difference between the apoptotic index/Ki-67 labelling index and clinicopathological parameters. CONCLUSION: We propose that cell proliferation is more closely associated with gastric adenocarcinomas than apoptosis is, but that neither has any clinical significance as a prognostic factor in gastric adenocarcinomas.

BACKGROUND: The purpose of this retrospective study was to determine the prevalence of sarcopenia and sarcopenic obesity among patients who underwent orthopedic surgery (OS). METHODS: A total of 222 patients were reviewed immediately after or prior to OS. In the control group, 364 patients from outpatient departments (OPDs) who did not have any OS were enrolled. Whole-body dual-energy X-ray absorptiometry was used to analyze body composition. Skeletal muscle mass was adjusted for height squared, total body weight, and height and fat mass (residuals). Obesity was defined as body mass index (BMI) > 25.0 kg/m2. RESULTS: The prevalence of sarcopenia in the OS group was 25.7%, 44.1%, and 26.6%, respectively, according to the 3 different criteria. The prevalence was significantly lower in the OPD group (6.0%, 33.1%, and 14.8%, respectively). The highest rates of sarcopenia with height-adjusted definition were seen in patients with a femoral neck fracture. In the multivariate analysis, factors associated with sarcopenia were male gender, older age, and lower BMI (odds ratio [OR]: 28.38, 1.03, and 1.83, respectively) when muscle mass was adjusted for height, whereas male gender, older age, and higher BMI were associated with sarcopenia (OR: 1.04, 2.57, and 1.83, respectively) when adjusted for weight. When residuals were used as a cutoff, decreased BMI and total hip bone mineral density (0.1 g/cm2) were independent risk factors associated with sarcopenia (OR: 1.09 and 1.05). The prevalence of sarcopenic obesity ranged from 1.8% to 21.2%. CONCLUSIONS: Our study demonstrated a high prevalence of sarcopenia among OS patients.

OBJECTIVES: We aimed to evaluate the clinical effects of the recently developed laser surgery in patients who were diagnosed by polysomnography as simple snorers. MATERIALS AND METHODS: We operated on 35 patients with apena index of below 5, using CO 2 laser, from June, 1993 through May, 1994 at Yongdong Severance Hospital. For these patients, we carried out before and after assessments of three different kind: first, a follow-up assessment of subjective symptoms, such as snoring, daytime somnolence, nocturnal arousal, and headache; second, a psychodynamic analysis done by a psychiatrist on insomnia and depression: and third, an assessment of subjective atisfaction for 24 weeks following the surgery. RESULTS: Snoring improved in 74.2% of the patients, and daytime somnolence improved in 80.0% of the patients. Nocturnal arousal showed improvement in all the subjects whereas headache showed improvement in 66. 7% of the patients. In the psychodynamic analysis, insomnia as observed in 22.9% of the subjects, showing significant improvemnt. However, depression didn't improve significantly. Subjecive satisfaction of the surgery was noted to be the greatest at the fouth week of the operation but it gradually decreased thereafter. The most common postoperative complication was foreign body sensation (31.4%), which disappeared spontaneously within 3 to 6-months of the operation. CONCLUSION: Laser snoring surgery in simple snorers is found to be an effective method to lessen snoring. However, patients should be informed beforehand that this method of surgery may not fully meet their expectations.
