Helicobacter pylori can cause variety of upper gastrointestinal disorders such as peptic ulcer, mucosa associated lymphoid tissue (MALT)-lymphoma, and gastric cancer. The prevalence of H. pylori infection has significantly decreased in Korea since 1998 owing to active eradication of H. pylori. Along with its decrease, the prevalence of peptic ulcer has also decreased. However, the mean age of gastric ulcer increased and this is considered to be due to increase in NSAID prescription. Gastric cancer is one of the leading causes of cancer deaths in Korea and Japan, and IARC/WHO has classified H. pylori as class one carcinogen of gastric cancer. Despite the decreasing prevalence of H. pylori infection, the total number of gastric cancer in Korea has continuously increased from 2006 to 2011. Nevertheless, the 5 year survival rate of gastric cancer patients significantly increased from 42.8% in 1993 to 67% in 2010. This increase in survival rate seems to be mainly due to early detection of gastric cancer and endoscopic mucosal dissection treatment. Based on these findings, the prevalence of peptic ulcer is expected to decrease even more with H. pylori eradication therapy and NSAID will become the main cause of peptic ulcer. Although the prevalence of gastric cancer has not changed along with decreased the prevalence of H. pylori, gastric cancer is expected to decrease in the long run with the help of eradication therapy and endoscopic treatment of precancerous lesions.

To determine the approximate incidence and clinical features of pernicious anemia in a Korean population, we retrospectively analyzed clinical data for patients with pernicious anemia who were diagnosed between 1995 and 2010 at five hospitals in Chungnam province. Ninety-seven patients were enrolled, who accounted for 24% of patients with vitamin B12 deficiency anemia. The approximate annual incidence of pernicious anemia was 0.3 per 100,000. The median age was 66 (range, 32-98) yr, and the male/female ratio was 1.25. Anemia-associated discomfort was the most common symptom (79.4%), followed by gastrointestinal and neurological symptoms (78.4% and 38.1%, respectively). Pancytopenia was found in 36 patients (37.1%), and autoimmune disorders were found in 15 patients (15.5%). Antibody to intrinsic factor was detected in 62 (77.5%) of 80 patients examined, and antibody to parietal cells was detected in 35 (43.2%) of 81 patients examined. Of the 34 patients who underwent tests for Helicobacter pylori, 7 (12.5%) were positive. The anemia-associated and gastrointestinal symptoms resolved completely in all patients after intramuscular injection of cobalamin, whereas neurological symptoms remained in some. In conclusion, pernicious anemia is less frequent in Koreans than in Western populations; however, the clinical features of this disorder in Koreans do not differ from those of Western cases.

BACKGROUND/AIMS: Gastrointestinal (GI) symptoms are common among patients with non-insulin dependent diabetes mellitus (NIDDM). Our aim was to investigate the frequency of chronic GI symptoms in Korean patients with NIDDM. METHODS: A cross-sectional survey, using a reliable and valid questionnaire, was performed in diabetes clinics from seven hospitals of the Catholic University of Korea. RESULTS: A total of 608 patients (249 males and 359 females, mean age 53.7+/-10.9 years) were investigated. The frequencies of weekly heartburn and acid regurgitation (esophageal symptoms) were 7.1% (95% confidence interval [CI], 5.0 to 9.2) and 4.4% (95% CI, 2.8 to 6.1), respectively. The frequency of dyspepsia was 13.2% (95% CI, 10.5 to 15.8). The frequencies of constipation and diarrhea were 15.0% (95% CI, 12.2 to 18.0) and 5.3% (95% CI, 3.5 to 7.1), respectively. Nausea and the use of manual maneuvers to facilitate defecation were more prevalent in women than in men. Constipation and fecal incontinence were more common in diabetes patients with long duration (>10 years). Fecal incontinence and using laxatives were more frequent in the complicated diabetes group. Using laxatives was more frequent in the uncontrolled diabetes group. CONCLUSIONS: Two-thirds of diabetic patients experienced GI symptoms. The prevalence of GI symptoms was more common in patients who had diabetic complications and a long duration of diabetes.

BACKGROUND/AIMS: To estimate the prevalence and evaluate the associated psychological factors of functional gastrointestinal disorders (FGIDs) in males in their twenties who are currently enrolled in military service. METHODS: A total of 1,073 men in the Korean army were asked to complete questionnaires based on the Rome III criteria and Symptom Checklist-90-revised (SCL-90R). The prevalence of FGIDs was estimated, and the associated psychological factors were evaluated. RESULTS: A total of 967 men participated. The total prevalence of FGIDs was 18.5% (age-adjusted prevalence, 18.1%; 95% confidence interval [CI], 15.3% to 20.8%). The total SCL-90R scores were higher in men with FGIDs than men without FGIDs (24 [interquartile range, 13 to 44] vs 13 [5 to 28], p<0.001) and higher in men with overlapping syndromes than in those with single FGIDs (31 [18 to 57] vs 14 [5.75 to 29], p<0.001). Somatization (odds ratio [OR], 1.141; 95% CI, 1.09 to 1.20; p<0.001), obsessive-compulsive behaviors (OR, 1.084; 95% CI, 1.03 to 1.14; p=0.002) and depression (OR, 0.943; 95% CI, 0.90 to 0.99; p=0.020) were identified as independent predictive factors for FGIDs. CONCLUSIONS: FGIDs are common among men in their twenties who are fulfilling their military duty. Somatization and obsessive-compulsive features from the tense atmosphere are associated with the development or progression of FGIDs. Patients who exhibit overlapping syndromes require greater attention given their more severe psychopathology.

INTRODUCTIONPeutz-Jeghers Syndrome (PJS) is an uncommon autosomal dominant hamartomatous polyposis syndrome. Morbidity arises from polyp-related complications and increased risks of malignancy. We report on PJS patients registered in the Singapore Polyposis Registry, identified principal causes of morbidity and appraised current management strategies. A followup protocol based on recent literature has been proposed.

MATERIALS AND METHODSA search of a prospectively collected database in the Singapore Polyposis Registry was made. Only patients who fulfilled the diagnostic criteria of PJS were included. The clinical records were retrieved for review. Information on affected family members was obtained from the Registry's pedigree records.

RESULTSSeven unrelated patients fulfilled the criteria of having PJS. Principal causes of morbidity include recurrent bouts of abdominal colic, episodes of intestinal obstruction, gastrointestinal bleeding and the need for repeated laparotomies. Six out of 7 patients had initial presentation with acute intestinal obstruction requiring emergency laparotomy. Management was mostly problem-oriented and marked inter-surgeon variation with regard to cancer screening and genetic counselling was observed.

CONCLUSIONPatients with PJS suffer gastrointestinal complications from polyposis and are at increased risks for developing cancers. A move towards surveillance and planned comprehensive care may reduce the morbidity of the condition. A protocol driven approach conducted in the setting of a Polyposis Registry is ideally suited to facilitate such care.

OBJECTIVES: To investigate the etiologies of urinary bladder involvement in patients with systemic lupus erythematosus (SLE), the clinicoradiologic features of gastrointestinal tract manifestations and clinical outcomes in patients with lupus cystitis accompanied by gastrointestinal manifestations. METHODS: We conducted a retrospective chart review on 413 patients with SLE. Patients were selected for review on the basis of lower urinary tract symptoms including urinary frequency, urgency and urinary incontinence. Radiologic studies were analyzed in patients with lupus cystitis. RESULTS: Ten consecutive patients, complicated with lower urinary tract symptoms, were identified. Underlying etiologies were as follows: lupus cystitis in five, neurogenic dysfunction secondary to transverse myelitis in three, cyclophosphamide-induced cystitis in one and tuberculous cystitis in one patient. All patients with lupus cystitis showed gastrointestinal manifestations, such as abdominal pain, nausea, vomiting and/or diarrhea during the periods of cystitis symptoms. In all patients with lupus cystitis, paralytic ileus was demonstrated on plain abdominal X-ray and ascites, bilateral hydroureteronephrosis and thickened bladder wall were identified on abdominal ultrasound or CT. Abdominal CT revealed bowel wall thickening in four of the five patients. The main sites of thickened bowel on abdominal CT were territory supplied by superior mesenteric artery. Two of five patients with lupus cystitis expired during the follow-up period. CONCLUSION: Diverse etiologies may cause lower urinary tract symptoms in patients with SLE. Lupus cystitis is strongly associated with gastrointestinal involvement and abdominal CT can be a useful radiologic tool to investigate the gastrointestinal tract involvement in patients with lupus cystitis.

OBJECTIVEChronic granulomatous disease (CGD) is a rare primary immunodeficiency of phagocytic oxidative bursts leading to recurrent severe bacterial and fungal infections as well as granuloma formation. There were few reports on the clinical characteristics of this disease in China. The purpose of this study was to evaluate the clinical features of 48 Chinese cases with CGD which were confirmed by clinical features, dihydrorhodamine (DHR) assay and gene mutation analysis.

METHODThe study cohort was the population of CGD patients diagnosed in Children's Hospital of Fudan University from January, 2004, to June, 2011. Cases included in our analysis were restricted to those who had complete data of the clinical symptoms and laboratory tests. The patients were followed up by outpatient visiting and telephone call regularly for 0.5 to 6 years. The history and data of physical examination and treatment of 48 cases were collected and reviewed.

RESULTAll the patients were diagnosed by DHR analysis. The age of onset of all the 48 patients were less than 6 months, including 43 male and 5 female. The mean age at diagnosis was 2.42 years; 12 patients were infants under six months, 10 were between 6 and 12 months, 9 were between 1 and 2 years, 5 patients were between 2 and 3 years, 4 were between 4 and 5 years, and 8 were between 6 and 10 years. Recurrent respiratory infection (44/48) and chronic diarrhea (31/48) were the common symptoms in all the patients, and then skin lesion (22/48), including marked reaction at BCG infected site, pustular eruption and infected skin ulcer and urinary tract infection (3/48) were also general symptoms in our study. In addition, lymphadenectasis occurred in 31 cases and 23 of them were considered to be associated with BCG vaccination. The pathogens caused the infection were mycobacteria (52.08%), fungi (43.75%) and pyogenic bacteria. Thirty-seven patients had mutations in CYBB/CYBA/NCF1/NCF2 genes. Recombinant human interferon-gamma (rhIFN-γ) plus sulfamethoxazole were used for the prevention and treatment of infection, the frequency and severity of the disease could be reduced.

CONCLUSIONThe age at onset and diagnosis of the present group of CGD was younger. Clinical symptoms were associated with recurrent mycobacterial, fungal and pyogenic bacterial infection, which involved respiratory tract, alimentary tract, skin and lymph node. rhIFN-γ partially improved the prognosis of CGD.

: Anaphylaxis is a predominantly childhood disease. Most of the literature on anaphylaxis has emerged from Western countries. This study aimed to describe the incidence, triggers and clinical presentation of anaphylaxis among children in Singapore, look for predictors for anaphylaxis with severe outcomes, and study the incidence of biphasic reactions.: We retrospectively reviewed records of children presenting with anaphylaxis to our paediatric emergency department from 1 January 2007 to 31 December 2014.: We identified 485 cases of anaphylaxis in 445 patients. Cutaneous symptoms (urticarial/angio-oedema) were the most common across all age groups (481 cases, 99%), followed by respiratory (412, 85%), gastrointestinal (118, 24%) and cardiovascular (35, 7.2%) symptoms. Central nervous system symptoms (drowsiness/ irritability) were rare across all age groups (11, 2.2%). Food was identified as the most common trigger across all age groups (45% to 63%). Seafood was the most common food trigger (57, 25%). A total of 420 (86.6%) children were treated with adrenaline, 451 (93%) received steroids and 411 (85%) received antihistamines. Sixty-three (13%) children fulfilled the criteria of severe anaphylaxis. There was no statistically significant association between severe anaphylaxis and the type of trigger (= 0.851), nor an overall past history of atopy (= 0.428). The only independent predictor for severe anaphylaxis was a previous drug allergy (= 0.016). A very low prevalence of biphasic reactions (0.6% of study population) was noted in our study.: We described the presentation and management of anaphylaxis in the Singapore population. A history of drug allergy is associated with severe presentation. Biphasic reactions are rare in our population.

BACKGROUND/AIMS: The increasing incidence of cardiovascular disease has led to an increase in the frequency of upper gastrointestinal (GI) hemorrhage due to the use of antiplatelet agents. This study examined the clinical characteristics of patients with upper GI hemorrhage who were administered aspirin alone or a combination treatment of antiplatelet agents. METHODS: A 656 patients who underwent drug-eluting coronary stenting at Ewha Mokdong Hospital in 2008 were divided into three groups according to the antiplatetlet agents used after the intervention; groups of aspirin alone, aspirin plus clopidogrel, and aspirin, and clopidogrel plus another antiplatelet agent, respectively. Patients admitted with GI hemorrhage in the same period without a medication history of antiplatelet or nonsteroidal anti-inflammatory drugs were used as the control hemorrhage group. The medical records were reviewed. RESULTS: Significant GI symptoms were observed in 21.1% of total patients, of whom 48.2% had ulcers. The upper GI hemorrhage rate was 3.8%. There was no significant difference in the hemorrhage rate between three groups. Compared to the control hemorrhage group, the endoscopic variables of the antiplatelet-related hemorrhage group were not significantly different. However, the Helicobacter pylori infection rate was lower, the admission period was longer, and the mortality rate was higher in the antiplatelet-related hemorrhage group (p<0.05, respectively). There was no direct association between restarting or discontinuance of antiplatelets after the hemorrhage event and mortality. CONCLUSIONS: Adding other antiplatelet agents to aspirin did not increase the hemorrhage rate. However, active diagnostic and therapeutic efforts are recommended in patients with GI symptoms during antiplatelet therapy.
