Tuberculosis remains an important cause of morbidity and mortality, especially in underdeveloped and developing nations. Manifestations could be nonspecific and may mimic many other conditions, including malignancies. Oesophageal involvement is surprisingly rare despite the high prevalence of pulmonary tuberculosis and the close proximity of these two structures. We report two cases of oesophageal tuberculosis; a 73-year-old man with simultaneous oesophageal, stomach and duodenal involvement, and a 45-year-old man with isolated oesophageal involvement. Underlying malignancies were initially suspected in both cases, but they were eventually diagnosed as tuberculosis.

Hepatosplenic candidiasis is also called chronic disseminated candidiasis and usually seen in patients with hematologic malignancies who have just recovered from an episode of neutropenia. Gastric candidiasis most commonly present as a mucosal lesion such as an ulcer or erosions, but other gastric lesion is very rare. We experienced a case of gastric candidiasis which presented as gastric subepithelial mass in a 60-year old woman who had undergone the 2nd consolidation chemotherapy due to acute myeloid leukemia. The pathologic diagnosis was confirmed by fine needle aspiration of the gastric subepithelial mass under the guidance of endoscopic ultrasonography.

INTRODUCTIONThe use of an additional biopsy from the gastric body may help improve the detection of Helicobacter pylori during endoscopy. This study aimed to determine whether such an additional biopsy is necessary in routine rapid urease test (RUT), and whether acid suppression and antibiotic therapy affect RUT results.

METHODSPatients recruited had two gastric mucosal biopsies taken - one from the gastric antrum and the other from the gastric body. Each biopsy was placed into separate RUT kits. Information on previous or current use of proton-pump inhibitors, H2 receptor antagonist, bismuth and antibiotics was obtained. Patients on any of those drugs one week prior to endoscopy were considered to have a positive drug history (PDH).

RESULTSOf the 400 patients recruited, 311 had negative RUTs and 89 had at least one positive RUT. Between the PDH and negative drug history (NDH) groups, there was a significant difference in the distribution of the location of the biopsies that yielded positive RUTs (p = 0.023). The NDH group had a higher proportion of patients who had positive RUTs for both locations, whereas the PDH group had a higher proportion of patients who had positive RUTs for only one location.

CONCLUSIONAs RUT results are significantly affected by the use of acid suppression and antibiotic therapies, biopsies for RUT should be taken from both the gastric antrum and body to minimise false negative results.

BACKGROUND/AIMS: Although previous reports suggested that pepsinogen (PG) I/II ratio was the index of gastric atrophy, PG I/II ratio was also related to other factors such as Helicobacter pylori (H. pylori) infection, various gastrointestinal diseases, and aging. The aim of this study was to evaluate the relationship between serum PG I/II ratio and age or upper gastro-intestinal diseases according to H. pylori infection status. METHODS: A total of 529 individuals (307 male; mean age, 57.2 years) were divided into 4 groups (94 gastric ulcers, 35 duodenal ulcers, 105 reflux esophagitis, and 295 atrophic gastritis) according to endoscopic diagnosis. H. pylori infection was determined by H. pylori IgG antibody (ELISA) and PG was measured by latex immunoassay. RESULTS: H. pylori infected patients showed markedly increased serum PG II levels (24.0+/-14.7 ng/mL vs. 13.8+/-16.6 ng/mL, p<0.001) and low PG I/II ratio (3.9+/-2.0 vs. 6.0+/-2.5, p<0.001) than non-infected subjects. In H. pylori infected patients, mean PG I/II ratios in the gastric ulcer and atrophic gastritis group were significantly lower than those of the duodenal ulcer and reflux esophagitis group (p<0.001, ANOVA, Turkey's multiples comparison test). The mean ratio of open type atrophic gastritis was lower than that of close type atrophic gastritis (3.0+/-1.4 vs. 3.8+/-1.7, p<0.005). PG I/II ratio gradually decreased with age in H. pylori-infected patients with atrophic gastritis (R(2)=0.9, p=0.005, linear regression analysis). CONCLUSION: Serum PG I/II ratio reflects H. pylori infection and gastric atrophy. In the presence of H. pylori infection, gastric atrophy progresses with age.

Spontaneous bacterial peritonitis (SBP) is the most common infection in liver cirrhosis patients, and is not a result of surgery or intra abdominal infection. Argon plasma coagulation (APC) is an endoscopic procedure used with a high-frequency electrical current for control of bleeding from gastrointestinal vascular ectasias including angiodysplasia and gastric antral vascular ectasia. This procedure is known to be safe because it uses a noncontact method. Therefore, tissue injury is minimal and up to two to three millimeters. However, we experienced a case of SBP occurring immediately after performance of APC for control of severe bleeding from angiodysplasia in the colon in a patient with liver cirrhosis and hepatocellular carcinoma.

OBJECTIVETo study the relationship of the types of Helicobacter pylori (H. pylori) strains with the classification and the severity of chronic gastro-duodenal diseases in children.

METHODSOne hundred and fifteen children with chronic upper gastrointestinal symptoms who were diagnosed as H. pylori infection by gastroscopy were enrolled in this study. H. pylori strains were serotyped by immunoblot technique. The gastric biopsy specimens of all patients were studied histologically.

RESULTSType I H. pylori strains were confirmed in 84 cases (73.0%), intermediate type strains in 21 cases (18.3%), and type II strains in 10 cases (8.7%). Type I H. pylori strains infection caused a moderate gastric mucosal inflammation in 83 cases and a severe inflammation in 1 case. Intermediate type H. pylori strains infection caused a moderate gastric mucosal inflammation in 21 cases. Type II H. pylori strains infection caused a mild gastric mucosal inflammation in 2 cases and a moderate inflammation in 8 cases. Different types of H. pylori strains resulted in different severity of gastric mucosal inflammation (x2=15.444, P < 0.01). The gastric mucosal inflammation due to type I H. pylori strains was the most severe, while the inflammation due to type II H. pylori strains was relatively mild. The incidence of nodulus lymphaticus of gastric mucosa due to type I, type II and intermediate type H. pylori strains infection was 76.2%, 47.6% and 40.0%, respectively (x2=10.171, P < 0.01). The classification of chronic gastro-duodenal diseases was not associated with the types of H. pylori strains.

CONCLUSIONSType I strains were the leading cause of H. pylori infection in children. All of types of H. pylori strains can cause pathohistologic changes of gastric mucosa. Type I H. pylori strains infection can result in the most severe gastric mucosal inflammation and the highest incidence of nodulus lymphaticus. The immunoblot serotyping of H.pylori strains may be useless for the classification of chronic upper gastrointestinal diseases but it is helpful for the evaluation of the severity of the diseases in children.
