ABSTRACT
The prevalence of reflux esophagitis is increasing in Korea. To estimate the prevalence and clinical characteristics of reflux esophagitis in healthy subjects, we retrospectively examined the medical records of healthy subjects undergoing a routine check-up from October 2004 to September 2005. A total of 6,082 (3,590 men, mean age 44+/-10 yr) subjects were enrolled in this study. The prevalence of reflux esophagitis in healthy subjects was 10.5%. According to the univariate analysis, male sex (odds ratio [OR] 3.49, 95% confidence interval [CI] 2.84-4.30), smoking history (OR 1.91, 95% CI 1.60-2.28), body mass index (BMI) >30 kg/m2 (OR 2.13, 95% CI 1.37-3.33), total cholesterol >250 mg/dL (OR 1.50, 95% CI 1.05-2.14), low-density lipoprotein (LDL) cholesterol > or =160 mg/dL (OR 1.52, 95% CI 1.08-2.14), triglyceride > or =150 mg/dL (OR 1.92, 95% CI 1.61-2.30), high blood pressure (BP) (OR 1.46, 95% CI 1.20-1.76), and fasting glucose > or =110 mg/dL (OR 1.45, 95% CI 1.13-1.86) were significantly associated with reflux esophagitis (all p<0.05). However, age, alcohol drinking and Helicobacter pylori infection were not associated with reflux esophagitis. In conclusiosn, significant relationships of reflux esophagitis with obesity, low high-density lipoprotein (HDL) cholesterol, high triglyceride, high BP, and elevated fasting glucose suggested that reflux esophagitis might represent the disease spectrum of the metabolic syndrome.

BACKGROUND/AIMS: It is not clear whether the anti-secretory therapy should be continued for symptomatic relief and ulcer healing before or after the eradication of H. pylori in patients with peptic ulcer disease. The aim of this study was to evaluate the effectiveness of additional anti-secretory therapy before or after H. pylori eradication in peptic ulcer disease. METHODS: Thirty eight patients with H. pylori-positive active peptic ulcer were included. Patients were randomly allocated into 3 groups; standard 1-week triple therapy followed by omeprazole (20 mg, qd) for 3 weeks (group A), standard 1-week triple therapy only (group B), and omeprazole (20 mg, qd) for 3 weeks followed by 1-week triple therapy (group C). Endoscopy with the rapid urease test and histology for H. pylori was performed 4-8 weeks after the completion of treatment. The symptom was scored by a visual analog scale. RESULTS: Of the 38 patients, 10 were excluded from the per-protocol analysis of this study. The H. pylori eradication rates were 87.5% (group A), 80.0% (group B) and 90.0% (group C) respectively. The peptic ulcer healing rates were 100% in group A, 70.0% in group B, and 90.0% in group C. There was no difference in H. pylori eradication rates and ulcer healing rates among three groups (p>0.05). Symptom score differences between pre-treatment and post-treatment group were not significantly different (p>0.05). CONCLUSIONS: The standard one week triple therapy with or without 3-weeks anti-secretory treatment with omeprazole before or after the therapy does not affect H. pylori eradication rates, peptic ulcer healing rates, and symptom score improvement.

BACKGROUND/AIMS: Peristomal infection is the most common complication of percutaneous endoscopic gastrostomy (PEG) insertion. Methicillin-resistant Staphylococcus aureus (MRSA) is the most commonly implicated organism of peristomal infection. The aims of this study were to determine the contribution of nasal MRSA to wound infection in PEG and the predictors of wound infection. METHODS: A prospective study was conducted on patients undergoing PEG between September 2003 and July 2005. All patients received antibiotics prior to PEG insertion. Nasal swabs were taken from a consecutive series of patients prior to PEG insertion. Wound status of the peristomal site were prospectively evaluated at day 1, 3, and 7 following the insertion of PEG. RESULTS: Thirty-one patients underwent PEG insertion (mean age, 66+/-16 years). Ten patients (32.3%) had MRSA-positive nasal swabs. Peristomal infection did not have any relationship with nasal MRSA colonization (p>0.05). Peristomal infection occurred in 4 (12.9%) cases. The rate of peristomal infections was significantly higher in patients with diabetes mellitus (p<0.05). CONCLUSIONS: Nasal MRSA colonization is not associated with the risk of peristomal infections in patients receiving antibiotics prior to PEG insertion. Diabetes mellitus might be the risk factor for peristomal infection after PEG insertion.

Vaccination against hepatitis A virus (HAV) is recommended for patients with chronic liver disease (CLD), but this has been deemed unnecessary in Korea since the immunity against HAV was almost universal in adults. However, this practice has never been reevaluated with respect to the changing incidence of adult acute hepatitis A. We retrospectively reviewed the medical records of 278 patients with acute hepatitis A diagnosed from January 1995 to November 2005 and prospectively tested 419 consecutive CLD patients from July to December 2005 for the presence of IgG anti-HAV. The number of patients with acute hepatitis A has markedly increased recently, and the proportion of adult patients older than 30 yr has been growing from 15.2% during 1995-1999, to 28.4% during 2000-2005 (p=0.019). Among 419 CLD patients, the seroprevalences of IgG anti-HAV were 23.1% for those between 26 and 30 yr, 64% between 31 and 35 yr, and 85.0% between 36 and 40 yr. These data demonstrate that immunity against HAV is no more universal in adult and substantial proportion of adult CLD patients are now at risk of HAV infection in Korea. Therefore, further study on seeking proper strategy of active immunization against HAV is warranted in these populations.

Giant duodenal ulcer can be defined as a variant of peptic ulceration that exceeds 2 cm at the greatest diameter. The high mortality and morbidity of giant duodenal ulcer are directly related to the resultant perforation, obstruction and massive hemorrhage. The patient usually has a long history of an inadequately treated or neglected peptic ulcer, but this malady is rarely induced by nonsteroidal anti-inflammatory drugs (NSAIDs). A 60-year-old man was referred to us due to epigastric pain. He underwent appendectomy 1 week ago, and he was administered ketorolac (tarasyn(R)) for 5 days to control the postoperative pain. Esophagogastroduodenos copy (EGD) revealed a giant duodenal ulcer encircling the lumen from the pylorus to the postbulbar portion of the duodenum, and he was then treated with proton pump inhibitor. Two weeks later, the follow-up EGD showed complete duodenal obstruction at the bulb. He was treated by laparoscopic gastrojejunostomy. We report here on this case of duodenal obstruction that was induced by the short-term use of NSAIDs.

A NK/T cell lymphoma is highly aggressive lymphoma of a putative NK-cell origin with a predominant extranodal presentation and a rapidly fatal course. CD56 has been reported to be the most reliable marker for a NK/T cell lymphoma. A NK/T cell lymphoma is strongly associated with the Epstein-Barr virus. We report a case of an aggressive NK/T cell lymphoma presenting as a gastric ulcer. A 52-year-old female patient presented with hematochezia and fever. The endoscopic finding showed a gastric ulcer with a recent bleeding stigma. Histologically, the gastric biopsy showed a diffuse infiltration of small or medium sized lymphoma cells with an angiocentric growth pattern and necrosis. The lymphoma cells were CD56+, CD3+, CD20-, which are consistent with a NK/T cell lymphoma. Unfortunately, the patient was discharged without treatment. We report this case with a review of the relevant literature.

BACKGROUND/AIMS: The aim of this study was to investigate the relationships between the clinical manifestations and the colonoscopic findings of ischemic colitis. METHODS: From March 2000 to June 2005, the data of 69 patients diagnosed with ischemic colitis were analyzed retrospectively. Statistical analysis was done by dividing the patients into two groups according to involved segments and also by again dividing the patients into two groups according to the mucosal findings that were gangrenous or not. RESULTS: The most common involved segment was the sigmoid colon (82.6%). The levels of total protein and albumin were significantly lower in the multisegmented group than in the non-multisegmented group (p=0.012, p=0.030, respectively), but there was no significant difference in the operation rate between the two groups. The WBC count and the level of serum glucose were significantly higher in the gangrenous group than in the non-gangrenous group (p=0.007, p=0.048, respectively). The operation rate was also higher in the gangrenous group (33.3%) than in the non-gangrenous group (3.5%) (p=0.011). CONCLUSIONS: Evaluating the severity of mucosal damage by colonoscopy may be helpful in predicting the clinical status and prognosis of the patients with ischemic colitis.

Cap polyposis is a rare intestinal disease that is characterized by the presence of inflammatory polyps consisting of elongated, tortuous and distended crypts that are covered by a 'cap' of granulation tissue. The pathogenesis and proper treatment of cap polyposis are still unclear. We experienced a case of cap polyposis, that was treated successfully by conservative management without the need for a pharmacotherapy or resection.

BACKGROUND AND OBJECTIVES: The purpose of the present study was to investigate the diagnostic accuracy of coronary stenoses in patients with ischemic heart disease using multidetector CT coronary angiography (MDCT) in the assessment of coronary artery disease. SUBJECTS AND METHODS: Forty-three patients (49-72yrs) undergoing conventional coronary angiography (CCA) were included in this study. All patients were premedicated with oral propranolol, 40-80 mg, to achieve an acceptable heart rate of less than 65 bpm, 1hr before the MDCT. All coronary arteries, including the distal segments and side branches, were assessed with respect to assessability and the presence of significant stenosis (>50%) and the results compared with those of CCA. RESULTS: Of the 645 coronary artery segments scanned, 540 were assessable (84%). A total 44 significant stenoses were detected by CCA and 49 lesions by MDCT. The overall sensitivity and specificity were 77 and 97%, respectively. The overall accuracy for the LAD, RCA and LCX was 94, 98 and 95%, respectively, and there were no differences in the accuracies in each vessel. The sensitivity in the proximal segments was much higher than in the distal segments. A total 15 segments were overestimated by the MDCT due to calcification and the small vessel size. CONCLUSION: MDCT, with improved spatial and temporal resolutions, and pre-treated with oral beta-blocker, permits the detection of coronary artery stenoses with a high degree of accuracy.

Hypertrophic cardiomyopathy (HCM) has been associated with sudden death in young athletes. On long-term follow up, syncope, chest pain and dyspnea are well known frequent symptoms due to the dynamic left ventricular outflow tract (LVOT) obstruction, mitral regurgitation and diastolic dysfunction. To reduce the LVOT pressure gradient, septal myectomy and alcohol injection have recently been utilized. However, some complications have been reported with alcohol ablation of the septal branches, such as complete atrioventricular block and alcohol spill over to ablate the entire left anterior descending coronary artery. Herein, a case of coil embolization of the septal branches, with successful reduction of the LVOT pressure gradient, is reported in a patient with HOCM.

Acetaminophen is a world-wide used analgesic and anti-pyretic drug with less anti-in-flammatory effect, available without prescription in most countries. Allergic-like reactions to this drug, including urticaria, angioedema, and anaphylactic reactions have only rarely been reported. This report describes a systemic reaction to acetaminophen documented by oral provocation test in a 30-year-old female patient with a history of anaphylaxis associated with acetaminophen use, in a subject who tolerated aspirin. After an oral challenge with 108.3 mg of acetaminophen, the subject had itching sensation of tongue. With a dose of 162.5 mg (cumulative dose 270.8 mg) acetaminophen, systemic urticaria and rash developed. Also, hand and facial angioedema and chest tightness were noted. Significant change of FEV1 was not noted. But, this patient has bronchial hyperresponsiveness. A rare acute hypersensitivity reaction to acetaminophen without aspirin sensitivity is described in this study. The results of study suggest an other mechanism rather than inhibition of cyclooxygenase as responsible.

BACKGROUND: PVD is a risk marker for coronary disease, cerebrovascular disease and many other conditions. One of the simplest, noninvasive and most useful parameters to objectively assess PVD is the ankle-brachial index (ABI). The aim of our study was to explore the frequency, severity and the risk factors of peripheral vascular disease in dialysis patients, especially according to dialysis modality. METHODS: We studied 85 maintenance dialysis patients (HD 50 patients, PD 35 patients) and control (n=73) who has normal serum creatinine without DM, hypertension. ABI was tested during about 2 hrs into the hemodialysis by doppler ultrasono (Smartdop 30, HADECO, Japan). The severity of PVD was stratified into 3 groups based upon ABI [normal (0.9 or =55 yrs), duration of dialysis and HD were negatively correlated with ABI: r= -0.309; p<0.01 for HD modality. Multiple regression analysis demonstrated that HD modality (than PD) predicted ABI with an adjusted R2=0.206 and p<0.01. CONCLUSION: We conclude that ABI was significantly decreased in HD pts than PD pts. The frequency of severe PVD was significantly higher in HD pts than PD pts. These findings suggest that dialysis modality may be related to the severity of PVD in the maintenance dialysis patients. Further studies are needed to understand the association between PVD and nutrition factors, inflammation markers and dialysis- or uremia-related factors in maintenance dialysis patients.

Actinomycosis is a chronic suppurative and granulomatous-disease caused by Actinomycosis israelli. Clinical presentation of the abdominal form of actinomycosis is nonspecific-pain, fever, leukocytosis, increased erythrocyte sedimentation rate, a sensation of abdominal mass and a formation of fistula. In addition, abdominal actinomycosis may mimic a carcinoma, diverticular abscess, inflammatory bowel disease, and tuberculosis. Most of abdominal actinomycosis develops after trauma, appendicitis, diverticulitis or gastrointestinal perforation. We report a case of abdominal actinomycosis preoperatively mimicking as colon carcinoma, which had no predisposing factors.

BACKGROUND: The mechanisms through which cellular activation results in intracellular mycobacterial killing is only partially understood. However, in vitro studies of human immunity to Mycobacterium tuberculosis have been largely modeled on the work reported by Crowle, which is complicated by several factors. The whole blood culture is simple and allows the simultaneous analysis of the relationship between bacterial killing and the effect of effector cells and humoral factors. In this study, we attempted to determine the extent to which M. tuberculosis is killed in a human whole blood culture and to explore the role of the host and microbial factor in this process. METHOD: The PPD positive subjects were compared to the umbilical cord blood and patients with tuberculosis, diabetes and lung cancer. The culture is performed using heparinized whole blood diluted with a culture medium and infected with a low number of M. avium or M. tuberculosis H37Ra for 4 days by rotating the culture in a 37degrees C, 5% CO2 incubator. In some experiments, methylprednisolone- or pentoxifylline were used to inhibit the immune response. To assess the role of the T-cell subsets, CD4+, CD8+ T-cells or both were removed from the blood using magnetic beads. The delta log killing ratio was defined using a CFU assay as the difference in the log number of viable organisms in the completed culture compared to the inoculum. RESULTS: 1. A trend was noted toward the improved killing of mycobacteria in PPD+subjects comparing to the umbilical cord blood but there was no specific difference in the patients with tuberculosis, diabetes and lung cancer. 2. Methylprednisolone and pentoxifylline adversely affected the killing in the PPD+subjects, umbilical cord blood and patients with tuberculosis. 3. The deletion of CD4+ or CD8+ T-lymphocytes adversely affected the killing of M. avium and M. tuberculosis H37Ra by PPD+ subjects. Deletion of both cell types had an additive effect, particularly in M. tuberculosis H37Ra. 4. A significantly improved mycobacterial killing was noted after chemotherapy in patients with tuberculosis and the delta logKR continuously decreased in a 3 and 4 days of whole blood culture. CONCLUSION: The in vitro bactericidal assay by human whole blood culture model was settled using a CFU assay. However, the host immunity to M. tuberculosis was not apparent in the human whole blood culture bactericidal assay, and patients with tuberculosis showed markedly improved bacterial killing after anti-tuberculous chemotherapy compared to before. The simplicity of a whole blood culture facilitates its inclusion in a clinical trial and it may have a potential role as a surrogate marker in a TB vaccine trial.

BACKGROUND/AIMS: The aim of this study was to investigate the value of colonoscopy for Salmonella-Shigella culture of biopsy specimen and intraluminal fluid during colonoscopy in patients with acute diarrhea. METHODS: From March 2001 to August 2001, sixty-six patients with watery or bloody diarrhea lasting less than 15 days were participated after exclusion of the patients with previous history or presumption of inflammatory bowel disease, radiation colitis, ischemic colitis, or pseudomembranous colitis. The biopsy specimen was taken and colonic luminal fluid was aspirated during colonoscopy for Salmonella-Shigella cultures. RESULTS: Male and female ratio was 1:1.3 and mean age was 45 17 years. The normal colonoscopic finding was showed in twelve cases (18.2%). The severity of acute colitis was mild in 25 cases (25/54, 46.3%), moderate in 9 cases (9/54, 16.7%), and severe in 20 cases (20/54, 37.0%). The extent of acute colitis was as followed: involvement of one segment in 9 cases (16.7%), involvement of two or more segments in 26 cases (48.1%), pancolitis in 7 cases (13.0%), and pancolitis with involved terminal ileum in 12 cases (22.2%). In culture study, identification of Salmonella species was in 11 cases (16.7%). Salmonella species were identified in 6.0% (3/50) with stool specimen, 18.0% (9/50) with biopsy specimen, and 4.0% (2/50) with intraluminal fluid, but without statistical significance. CONCLUSION: The culture using biopsy specimens and intraluminal fluid obtained during colonoscopy may be helpful in diagnosis of cases of suggesting Salmonella-Shigella infection.
