[preliminary study of the prevalence of helicobacter pylori in tananarive, madagascar and the antibacterial activity in vitro of 13 malagasy medicinal plants on this germ].helicobacter pylori infection has been studied in 60 patients who were suffering from either a peptic ulcer disease or a gastritis complaint. helicobacter pylori was searched in antral biopsy specimens using standard bacteriological methods (gram-staining urea-test, culture) and histological staining techniques (hematoxylin-eosin-saffron, undifferentiated giemsa). the culture was successful in 40 cases. the antibacterial activity of 13 malagasy medicinal plants has been tested versus helicobacte ...19911669364
[prevalence of helicobacter pylori infection in tananarive, madagascar].during a 8-month period, helicobacter pylori infection has been studied in 140 patients who presented upper gastrointestinal symptoms. helicobacter pylori was searched in antral biopsy specimens using standard bacteriological methods (gram-staining, urea-test, culture) and histological staining techniques (hematoxylin-eosin-saffron, undifferentiated giemsa). the global prevalence of h. pylori infection was 59%. the prevalence rates did not seem to differ with age and sex but h. pylori infection ...19979264755

helicobacter pylori in school children from the western province of sri lanka.little is known about the prevalence of helicobacter pylori in sri lanka and nothing is known about its prevalence in children. therefore the prevalence of h. pylori in a group of school children in sri lanka was determined.200111422474
pilot study of a low-cost clo test. 200212001609
prevalence of helicobacter pylori in sri lanka as determined by pcr.fifty-seven sinhalese patients were investigated for the presence of helicobacter pylori by pcr. a prevalence of 70.1%, with 47.5% positive for caga, was demonstrated. the most common vaca allele was s1am1. there was no significant association between either the s1 allele or the caga allele and severe gastroduodenal disease. there was an association between the s1 allele and the caga locus.200212089306
[antibiotic resistance of helicobacter pylori in reunion island: therapeutic consequences].the aims of this paper were to assess resistance of helicobacter pylori to antibiotics included in the so-called french triple regimens and to identify the possible causes of therapeutic failure in reunion island. antibiotic resistance was determined for 109 strains. all the strains were sensitive to amoxicillin and tetracycline, 93.6% were sensitive to ciprofloxacin, 92.7% to erythromycin and 60.6% to metronidazole. fifty three patients who had previously tested positive for h. pylori received ...200212145959
a pilot study of a low cost clo test. 200314735814
comparison of one week and two weeks of triple therapy for the eradication of helicobacter pylori in a sri lankan population: a randomised, controlled study.resistance of helicobacter pylori to antibiotics may be particularly high in parts of the tropics. infection may prove difficult to eradicate in such situations, and there is some evidence of benefit in increasing the duration of treatment (triple therapy) from 1 week to 2 or 3 weeks.200415693450
[seroprevalence of helicobacter pylori infection in malagasy population].helicobacter pylori is a worldwide infection. however very few data are actually available on h. pylori seroprevalence in the malagasy population. we carried out a transversal study in a sample of persons who met the following criteria: older than 15 years old, presence in the medicine internal unit 2 (university hospital center of antananarivo) during the period of the study whatever the reason. h. pylori infection was identified serologically by using elisa (g.a.p igg h. pylori elisa, bio-rad, ...200717402699
aetiology of recurrent abdominal pain in a cohort of sri lankan children.recurrent abdominal pain (rap) has a multifactorial aetiology with many affected children having no evidence of organic pathology. this study assessed the functional and organic causes for rap in a cohort of sri lankan children.200818377368
recurrent abdominal pain in children.recurrent abdominal pain is one of the commonest gastrointestinal complaints in children, affecting approximately 10% of school aged children and adolescents. there is no consensus with regards to etiology, investigation and management of this common problem. this review addresses some of the issues related to epidemiology, etiology, management and prognosis of recurrent abdominal pain.200919478352
presence of helicobacter pylori in betel chewers and non betel chewers with and without oral cancers.betel chewing has been shown to predispose to periodontal disease and oral cancer. studies show that people with gum disease are more likely to test positive for helicobacter pylori (h. pylori). it is not known if the lesions produced by betel quid and the resulting, chemical changes predispose to colonization by h. pylori. further the role of this organism in oral cancer is not known. our objective was to determine the presence of h. pylori in oral lesions of thirty oral cancer patients and to ...200919772630
