[ 1 ] - Gender is a risk factor in patients with gastroesophageal reflux disease
Background: Prevalence of gastroesophageal reflux disease (GERD) has increased in the last decades, and it is now one of the most common chronic and recurrent diseases. The present study aimed at determining the frequency of gender (sex) and age in Iranian patients with GERD symptoms. Methods: In this study, 803 patients aged 11 to 84 years, with erosive and nonerosive gastroesoph...
[ 2 ] - Relationship between esophageal clinical symptoms and manometry findings in patients with esophageal motility disorders: a cross-sectional study
Background: Manometry is the gold-standard diagnostic test for motility disorders in the esophagus. The development of high-resolution manometry catheters and software displays of manometry recordings in color-coded pressure plots have changed the diagnostic assessment of esophageal disease. The diagnostic value of particular esophageal clinical symptoms among patients suspected of esophageal m...
[ 3 ] - CagA and VacAgenotypes in peptic ulcer disease and non-ulcer dyspepsia: acase-control study
Background :The cag pathogenicity island includes a number of genes, including cytotoxin-associated protein A (cagA) and vacuolatingcytotoxin (vacA) genotypes, which are associated with bacterial virulence. Although the role of cagA and vacA in the virulence of Helicobacter pylori (H. pylori) is well-established in epidemiological studies, the relationship between the cagA and vacA genotypes ...
[ 4 ] - مانومتری با قدرت تفکیک بالا در افتراق اختلالات حرکتی مری
Background: High-resolution manometer (HRM) of the esophagus has become the main diagnostic test in the evaluation of esophageal motility disorders. The development of high-resolution manometry catheters and software displays of manometry recordings in color-coded pressure plots have changed the diagnostic assessment of esophageal disease. The first step of the Chicago classification described ...
[ 5 ] - آنتیبادی ضد CagA، روش جدید تشخیص بیماری زخم پپتیک از دیسپپسی بدون زخم: مطالعه مورد شاهدی
Background: Helicobacter pylori is a gram negative microaerophilic spiral bacilli, which causes duodenal and gastric ulceration. Also this organism cause distal gastric adenocarcinoma and primary gastric lymphoma. The most important Helicobacter pylorus virulence factor is cytotoxin associated gene A (cagA) Pathogenicity Island that cause secretion of antibody by stimulation of immune system. M...
