BACKGROUND/AIMS: Age, sex, gene and life style are modulating risks for colon cancer. Although alcohol intake may impact on colorectal adenoma, clear association has not been established yet. We aimed to investigate effects of alcohol consumption on the characteristics of colorectal adenoma. METHODS: Patients who underwent colonoscopic polypectomy of colorectal adenoma in the department of gastroenterology of Eulji hospital through 2005 to 2012, having both blood tests and ultrasound or abdominal CT examination were enrolled. The alcohol drinking patients were subdivided into normal or abnormal laboratory group, and alcoholic liver diseases group. RESULTS: 212 patients with colorectal adenoma were analyzed; advanced adenoma and multiple adenoma were found in 68 (32.0%) and 79 (37.2%) patients. When compared to the nondrinker group (120/212 patients), the alcohol drinker group (92/212 patients) represented significantly high odds ratios (ORs) for advanced adenoma (OR, 2.697; P=0.002), and multiple adenoma (OR, 1.929; P=0.039). Among alcohol drinker (92 patients), the ORs of advanced adenoma were 6.407 (P=0.003) in alcoholic liver diseases group (17 patients), 3.711 (P=0.002) in the alcohol drinker with abnormal lab (24 patients), and 2.184 (P=0.034), in the alcohol drinker with normal lab (51 patients) compared to nondrinker group. CONCLUSIONS: This study showed that alcohol drinking may influence on the development of advanced colorectal adenoma and multiplicity. Especially in the group with alcoholic liver diseases and with abnormal lab presented significantly higher ORs of advanced adenoma.

BACKGROUND/AIMS: The relationship between Crohn's disease and gallstones is established. However, the prevalence and risk factors for gallstones in patients with ulcerative colitis (UC) are not yet well understood. The aim of this study was to evaluate the prevalence and risk factors of gallstones in patients with UC. METHODS: This study was a retrospective single center study. A total of 87 patients with UC and 261 healthy controls were enrolled. Age, sex, and body mass index were matched. To investigate risk factors, the extent of UC, duration of disease, number of hospital admissions, and number of steroid treatments in patients with UC were evaluated. RESULTS: The prevalence of gallstones in patients with UC was 13.8%, whereas that in healthy controls was only 3.1% (P or =50 years of age had a 3.6-times higher risk of gallstones compared to that in those <50 years of age, and the difference was statistically significant (odds ratio, 3.60; confidence interval, 1.03-12.61) in univariate analysis. There were no statistically significant disease-related risk factors for gallstones in UC patients. CONCLUSIONS: This is the first study of gallstone prevalence in Korean UC patients. In this study, patients with UC had a higher prevalence of gallstones compared to that in well-matched healthy controls. Age seemed to be a possible risk factor, and more studies are needed. Further prospective, large-scale studies will be required to confirm the risk factors for gallstones in UC patients.

Spontaneous arterial bleeding has been reported rarely. In a patient consuming heavy amounts of alcohol with alcoholic liver cirrhosis, spontaneous bleeding can be evoked by thrombocytopenia, altered platelet function, and shear stress on fully dilated arteries by portal hypertension. Alcohol consumption itself can also predispose a patient to bleeding by influencing the aggregation and activation of platelets, and altering the coagulation and fibrinolysis pathway. All of these mechanisms could cause patients with alcoholic liver cirrhosis to bleed spontaneously; however, conditions inducing peripheral arterial bleeding are very rare. Here, we report three cases of spontaneous arterial bleeding in patients with liver cirrhosis consuming heavy amounts of alcohol. All of the patients bled without any physical trauma, and the involved arteries were the intercostal arteries in two cases and a gastroduodenal artery in the other case. The patients were treated by angiographic embolization. One expired due to recurrence of arterial bleeding despite repeated angiographic embolization and massive transfusion.

Amyloidosis is a group of disorders characterized by the extracellular accumulation of insoluble, fibrillar proteins in various organs and tissues. It is classified, on the basis of the identity of the precursor protein, as primary, secondary, or familial amyloidosis. Gastrointestinal amyloidosis usually presents as bleeding, ulceration, malabsorption, protein loss, and diarrhea. However, gastric amyloidosis with gastric outlet obstruction mimicking linitis plastica is rare. We report a case of gastrointestinal amyloidosis with gastric outlet obstruction in a patient with ankylosing spondylitis. The patient was indicated for subtotal gastrectomy because of the aggravation of obstructive symptoms, but refused the operation and was transferred to another hospital. Three months later, the patient died of aspiration pneumonia during medical treatment.

Foreign bodies in the upper esophagus should be removed as soon as possible to avoid serious complications. These foreign bodies can penetrate the bowel wall and cause severe complications. The peristalsis of the esophagus is not strong enough to prevent it from retaining swallowed objects. Hence, perforation from a foreign body is more likely to occur in the esophagus than in the rest of the gastrointestinal tract. A razor blade is a rare foreign body of the esophagus. Its sharpness and large size make it difficult to remove. A razor blade was very firmly impacted in the esophageal wall in our case, and the razor blade had not moved from the upper esophagus. A standard overtube has limitations to remove a razor blade inside the overtube's lumen. We report here on a case of using a wedge resected overtube made it possible to successfully extract a razor blade and no serious complications occurred after extraction of the razor blade.

Ischemic colitis is generally considered a disease of the elderly. The causes of ischemic colitis include low-flow states due to cardiac dysfunction or hypovolemia and certain medications including estrogen. Here we report a case of ischemic colitis in a 26-year-old woman. She had no specific medical history except taking oral-contraceptives for a long time. The mechanism of estrogen-induced ischemic colitis is not clearly understood. But we recommend that oral-contraceptives should be considered as a cause of ischemic colitis in young women.

BACKGROUND: Patients with type 2 diabetes have an increased risk of cardiovascular disease. Few studies have evaluated the cardiovascular disease (CVD) risk simultaneously using the United Kingdom Prospective Diabetes Study (UKPDS) risk engine and non-invasive vascular tests in patients with newly diagnosed type 2 diabetes. METHODS: Participants (n=380; aged 20 to 81 years) with newly diagnosed type 2 diabetes were free of clinical evidence of CVD. The 10-year coronary heart disease (CHD) and stroke risks were calculated for each patient using the UKPDS risk engine. Carotid intima media thickness (CIMT), flow mediated dilation (FMD), pulse wave velocity (PWV) and augmentation index (AI) were measured. The correlations between the UKPDS risk engine and the non-invasive vascular tests were assessed using partial correlation analysis, after adjusting for age, and multiple regression analysis. RESULTS: The mean 10-year CHD and 10-year stroke risks were 14.92+/-11.53% and 4.03+/-3.95%, respectively. The 10-year CHD risk correlated with CIMT (P<0.001), FMD (P=0.017), and PWV (P=0.35) after adjusting for age. The 10-year stroke risk correlated only with the mean CIMT (P<0.001) after adjusting for age. FMD correlated with age (P<0.01) and systolic blood pressure (P=0.09). CIMT correlated with age (P<0.01), HbA1c (P=0.05), and gender (P<0.01). CONCLUSION: The CVD risk is increased at the onset of type 2 diabetes. CIMT, FMD, and PWV along with the UKPDS risk engine should be considered to evaluate cardiovascular disease risk in patients with newly diagnosed type 2 diabetes.

BACKGROUND: When patients with chronic respiratory symptoms have a normal spirometry result, it is not always easy to consider bronchial asthma as the preferential diagnosis. Forced expiratory flow between 25% and 75% of vital capacity (FEF(25~75%)) is known as a useful diagnostic value of small airway diseases. However, it is not commonly used, because of its high individual variability. We evaluated the pattern of bronchodilator responsiveness (BDR) and the correlation between FEF25~75% and BDR in patients with suspicious asthma and normal spirometry. METHODS: Among patients with suspicious bronchial asthma, 440 adult patients with a normal spirometry result (forced expiratory volume in one second [FEV1]/forced vital capacity [FVC] > or =70% & FEV1% predicted > or =80%) were enrolled. We divided this group into a positive BDR group (n=43) and negative BDR group (n=397), based on the result of BDR. A comparison was carried out of spirometric parameters with % change of FEV1 after bronchodilator (DeltaFEV1%). RESULTS: Among the 440 patients with normal spirometry, FEF(25~75%)% predicted were negatively correlated with DeltaFEV1% (r=-0.22, p<0.01), and BDR was positive in 43 patients (9.78%). The means of FEF(25~75%)% predicted were 64.0+/-14.5% in the BDR (+) group and 72.9+/-20.8% in the BDR (-) group (p<0.01). The negative correlation between FEF(25~75%)% predicted and DeltaFEV1% was stronger in the BDR (+) group (r=-0.38, p=0.01) than in the BDR (-) group (r=-0.17, p<0.01). In the ROC curve analysis, FEF(25~75%) at 75% of predicted value had 88.3% sensitivity and 40.3% specificity for detecting a positive BDR. CONCLUSION: BDR (+) was not rare in patients with suspicious asthma and normal spirometry. In these patients, FEF(25~75%)% predicted was well correlated with BDR.

Delftia acidovarans is aerobic, nonfermentative Gram-negative rod commonly found in soil and water. Generally it is nonpathogenic but it unusually can cause bacteremia in immunocompromised patients. We present a case of peritonitis due to D. acidovorans in a patient on continuous ambulatory peritoneal dialysis. A 75-year-old woman was admitted with abdominal pain and cloudy peritoneal effluent. She was empirically treated with intraperitoneal (IP) cefazolin and ceftazidime, and then IP ceftazidime and oral ciprofloxacin, but peritonitis did not improve. Seven days after admission, D. acidovorans was identified from the peritoneal effluent, which was sensitive to amikacin, ceftazidime, ciprofloxacin and imipenem. Catheter removal was considered with regard to poor response to adequate antibiotics; however, 4 days after changing to IP imipenem/cilastatin, abdominal pain, the leukocyte count of peritoneal effluent and C-reactive protein decreased. She was treated with imipenem/cilastatin for two weeks and discharged with the dialysis catheter intact.
