BACKGROUND/AIMS: The meaning of specialized intestinal metaplasia (SIM) in the diagnosis of Barrett's esophagus (BE) is not clear. This study was designed to determine the clinical significance of SIM in the diagnosis of Barrett's esophagus. MATERIALS AND METHODS: Biopsies were taken from 601 subjects with endoscopically suspected columnar-lined esophagus. Under light microscopy with Alcian-blue stain, SIM was identified. Demographic characteristics, gastroesophageal (GE) reflux symptoms and endoscopic findings were compared between the SIM-present group and the SIM-absent group. RESULTS: Among 601 subjects, 184 (30.6%) were confirmed by pathology to have SIM. Age over 40 years (P<0.001) and a medication history of proton pump inhibitor or H2 blocker were found more frequently in the SIM-present group (P=0.01) than in the SIM-absent group. Any of 7 GE reflux symptoms (heartburn, acid regurgitation, chest pain, hoarseness, globus sensation, cough and epigastric soreness) were more frequent in the SIM-present group than SIM-absent group (P<0.001). Specifically, heartburn, chest pain and cough were significantly more common in the SIM-present group. There was no clinically significant difference associated with endoscopic findings or other clinical characteristics. CONCLUSIONS: When subjects with endoscopically suspected BE are analyzed based on the presence or absence of SIM, the SIM-present group was significantly associated with GE reflux symptoms suggestive of frequent GE reflux. However, the presence of SIM did not correlate with endoscopic findings.

BACKGROUND/AIMS: Chronic gastritis is a common finding during endoscopy and it is very important to describe it correctly. This study was designed to evaluate the distribution of endoscopic gastritis and the differences according to age, sex or area. MATERIALS AND METHODS: A clinical analysis was conducted on 25,536 subjects who had undergone an upper endoscopy for routine health check-up. Endoscopic gastritis was classified into four types, superficial gastritis, erosive gastritis, atrophic gastritis and intestinal metaplasia. The distribution of the four types of gastritis was evaluated according to sex, age and area. RESULTS: 51.6% of the patients had experienced at least one of the symptoms (epigastric pain or discomfort, soarness, dyspepsia, abdominal pain) on at least a few occasions during the previous year. The incidence of normal gastric finding was 3,593 (14.1%). 21,943 (85.9%) subjects have at least more than one of endoscopic gastritis. The number of cases with superficial gastritis was 7,983 (31.3%), erosive gastritis 6,054 (23.7%), atrophic gastritis 6,918 (27.1%), and intestinal metaplasia 1,181 (7.1%). Erosive gastritis, atrophic gastritis and intestinal metaplasia were more frequent in men than women (P<0.001) and in the older age group (> or =60 years) than younger age group (P<0.001). CONCLUSIONS: The prevalence of endoscopic gastritis was very common, 85.9%. In addition, erosive gastritis, atrophic gastritis and intestinal metaplasia were more frequent in men and in the older age group, which is similar to gastric cancer or peptic ulcer. Cautious regular endoscopic follow-up might be necessary regardless of gastrointestinal symptoms in Korea.

BACKGROUND: The aim of the present study was to determine the population-based prevalence of diabetes mellitus (DM) and prediabetes in a rural district of Daegu City, Korea. METHODS: Between August and November 2003, a community-based health survey of adults aged 20 years and older was performed in the rural district of Dalseong-gun in Daegu City. A total of 1,806 of all eligible individuals agreed to participate. Fasting plasma glucose was measured in all participants. Two hour oral glucose tolerance was measured in the 1,773 participants for whom there was neither an established diagnosis of DM nor evidence of DM according to fasting glucose levels. The prevalence of DM and prediabetes was determined according to the 2003 criteria of the American Diabetes Association. Subjects with prediabetes were classified into one of three categories of glucose intolerance: isolated impaired fasting glucose (IFG); isolated impaired glucose tolerance (IGT); or combined IFG and IGT. RESULTS: The prevalence of DM was 12.2%. The highest prevalence rates were observed in subjects in their seventies. A total of 34.7% of all subjects who were assigned a diagnosis of DM in the present study had not been diagnosed previously. The prevalence of prediabetes was 22.7%. The highest prevalence rates were observed in subjects in their fifties. CONCLUSION: The present study identified prevalence rates of 12.2% for DM (age-standardized prevalence rate [ASR], 6.8%), and 22.7% for prediabetes (ASR 18.5%). These results emphasize the need for community health promotion strategies to prevent or delay the onset of DM in individuals with prediabetes.

Turner syndrome is a chromosomal disorder in which of all or part one of the X chromosomes is absent, and this syndrome affects females. The syndrome leads to a constellation of physical findings that often includes congenital lymphedema, a short stature and gonadal dysgenesis. The prevalence of inflammatory bowel diseases in the general population is estimated to be 150~250 per 100,000 population. A 2-fold increase in the risk of developing inflammatory bowel diseases has been reported in women with Turner syndrome. We describe here a case of Turner syndrome with Crohn's disease.

The recently developed multislice computed tomography (MSCT) is capable of rapid imaging of cardiac structures, including coronary arteries, during a single breath-hold. We evaluated coronary artery bypass graft (CABG) patency by comparing MSCT results to those of contrast angiography. MSCT and contrast angiography were performed in 39 patients (10 women, 29 men and mean age 60.0 +/- 7.8 years) with a total of 115 bypass grafts including 36 left internal mammary arteries, 4 right internal mammary arteries, 19 radial arteries, 2 gastroepiploic arteries and 54 vein grafts. Patients were investigated for an average of 14 +/- 27 months (range 1 - 108 months) after CABG surgery. Contrast angiography showed a patency rate of 87.0% (100/115). Ninety-nine of these 100 patent grafts by contrast angiography and 14 of the remaining 15 occluded grafts were correctly classified by MSCT (93.3% sensitivity and 99.0% specificity for bypass graft occlusion). The positive and negative predictive values for bypass graft occlusion were 93.3% and 99%, respectively, with an overall diagnostic accuracy of 98.3% (97.2% for left internal mammary artery, 100% for radial artery, 98.1% for vein graft and 100% for other grafts). In conclusion, MSCT is a useful and accurate diagnostic tool for the evaluation of bypass graft patency.

BACKGROUND AND OBJECTIVES: Retension of inflammatory cells and cytokines in the middle ear cleft can result in ongoing chronic otitis media with effusion. This study aims to investigate the role of these inflammatory cells and cytokines in the middle ear effusion (MEE) of children with otitis media with effusion. MATERIALS AND METHOD: We analyzed 46 pediatric middle ear effusion samples for IL-6, IL-10, TNF-alpha and inflammatory cells and tried to elucidate the relationship between the concentration of these cytokines, inflammatory cells and clinical features. RESULTS: 1) The concentration of TNF-alphain MEE from children younger than 2 years was significantly higher than the levels of children older than 2 years (p<0.05). 2) The concentration of TNF-alpha in MEE of preoperative medication group was significantly lower than the levels of non-medication group (p<0.05). 3) The concentration of IL-6 in MEE of the ears with hearing threshold poorer than 35 dB was significantly higher than the levels of the ears with hearing threshold better than 35 dB (p<0.05). CONCLUSION: The results showed that TNF-alpha and IL-6 are intimately involved in the inflammatory cascade of the middle ear and suggest regulation of these cytokines as possible sites of future therapeutic intervention in otitis media with effusion.
