“…Among the various existing stains, one of the most recommended because of its simplicity and low cost is Giemsa staining (52,115,169,175) . Histological diagnosis and the urease test may show up to 95% sensitivity depending on the quality of material and expertise of the examiner (137,197) . Antisecretory drugs (H 2 receptor antagonists of histamine and proton pump inhibitors) and/or previous use of bismuth or antibiotics, by reducing the bacterial load, affect the accuracy of the urease test, so, whenever possible, an interval of two and 4 weeks respectively between suspending the drugs and the test is recommended (83,132) .…”

Significant progress has been obtained since the Second Brazilian Consensus Conference on Helicobacter pylori Infection held in 2004, in São Paulo, SP, Brazil, and justify a third meeting to establish updated guidelines on the current management of H. pylori infection. The Third Brazilian Consensus Conference on H pylori Infection was organized by the Brazilian Nucleus for the Study of Helicobacter, a Department of the Brazilian Federation of Gastroenterology and took place on April 12-15, 2011, in Bento Gonçalves, RS, Brazil. Thirty-one delegates coming from the five Brazilian regions and one international guest, including gastroenterologists, pathologists, epidemiologists, and pediatricians undertook the meeting. The participants were allocated in one of the five main topics of the meeting: H pylori, functional dyspepsia and diagnosis; H pylori and gastric cancer; H pylori and other associated disorders; H pylori treatment and retreatment; and, epidemiology of H pylori infection in Brazil. The results of each subgroup were submitted to a final consensus voting to all participants. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. Seventy per cent and more votes were considered as acceptance for the final statement. This article presents the main recommendations and conclusions to guide Brazilian doctors involved in the management of H pylori infection.

“…The results showed that the sensitivity and specificity of the test were 84.6% and 100%, respectively (27). Tseng et al (28) compared three different RUTs and found that the sensitivity of the tests was 86.2-93%, while the specificity was 100%. In concordance with medical literature, in our study, the sensitivity of the RUT was 92.86%, while the specificity was 100%.…”

Background/Aims: In this study we aimed to investigate the sensitivity and specificity of Narrow Band Imaging (NBI) in H. pylori gastritis and compare them with those of rapid urease test and urea breath test. Materials and Methods: A hundred sixty-five children who admitted to Uludag University Pediatric Gastroenterology Unit between October 2009-March 2011 with upper gastrointestinal symptoms were consecutively enrolled. During the endoscopy procedure gastric corporeal, antral and fundal images were obtained, afterwards the same areas were visualized with narrow band imaging and images were recorded again. Results: The study included 68 (41.2%) boys and 97(58.8%) girls. The mean age of the patients were 11.88±4.55. Tissue culture positivity and/or histopathological staining for H. pylori was determined in 56 (33.9%) patients (Group 1) and the other patients (n:109, 43.6%) didn't have an evidence of H. pylori infection (Group 2). Narrow band images have supported H. pylori infection in 56.4%. The sensitivity of narrow band images for determining H. pylori infection was 92.86% (95% CI 82.7-98), specificity was 62.39% (95% CI 52.6-71.5). Conclusion: Our study is the first to show the role of NBI in diagnosing H. pylori infection in children, as well as determining the sensitivity and specificity of the technique. The specificity is low; however, we suggest that the specific mucosal view of H. pylori gastritis provided by NBI is useful for identifying the areas from which the biopsies should be taken. Moreover, by using this technique, treatment of H. pylori infection may be initiated immediately without performing rapid urease test and without waiting for histopathology report and tissue culture.

“…The urease activity of the dental biofilm was measured by the use of a modified rapid urease test [18,22,23] in interproximal plaque samples from 4 interproximal sites (mesial aspect of 11, 26, 36, and 41). The urea broth used consisted of urea (10%) in distilled water and 0.02 g/L of phenol red; the pH was adjusted to 6.8.…”

Objective: To investigate oral diseases and microbiological conditions, such as the presence of ureolytic bacteria in dental plaque, in relation to experience of stomach pain in a remote adult Asian population.Methods: Ninety-three adults, 40–60-years old, from the Karen Hill tribe in Northern Thailand with no regular access to dental care were examined. Clinical registrations were performed and interproximal gingival plaque samples were collected and analyzed with the checkerboard (CKB) method for the presence of 14 oral bacterial species.Results: A number of 61 subjects reported daily stomach pain while 32 subjects had no symptoms from the stomach. The subjects with stomach pain had fewer remaining teeth (p < 0.05), higher caries experience (p < 0.05) and less BoP (p < 0.01). Most of the bacterial species were clustered statistically in three factors in a factor analysis, which together explained 65% of the microbiological variance. Factor 1, explaining 43.0% of the variance, was statistically associated with stomach pain (p < 0.001).Conclusions: The interproximal plaque/biofilm in adults of the study population showed a common presence of two gastrointestinal pathogens H. pylori and C. ureolyticus. The study also indicates for the first time a potential association between C. ureolyticus and stomach pain.
