Gastroesophageal reflux disease (GERD) is the main known etiological factor for Barrett's esophagus (BE), and BE is the precursor lesion of esophageal adenocarcinoma. The prevalence of BE is reported mostly from gastroenterology centers and there are only a few reported cases from outpatients with dyspepsia. A large number of patients with GERD have degrees of dyspepsia. This study primarily ai...

BACKGROUND Dyspepsia and headache frequently co-exist, but the clinical implication of this association is uncertain. We planned to examine the prevalence and impact of dyspepsia in adults with headache. METHODS A cross-sectional study was conducted in a secondary care setting. Clinical, psychological and health-related quality of life (HRQOL) data were compared between subjects with headache...

BACKGROUND Dyspepsia is a common health problem and most of the causes of dyspepsia are related to infection by Helicobacter pylori (H. pylori). Prevalence of H. pylori infection is different in different parts of the world. Purpose of our study was to determine the frequency of H. pylori infection in patients with dyspepsia in our setting where the prevalence of H. pylori was expected to be hi...

A validated postal questionnaire has been used to establish the prevalence of dyspeptic symptoms in five geographical locations from the south coast of England to the north of Scotland. The six month period prevalence of dyspepsia in the 7428 respondents to the questionnaire is 41% and equal between the sexes, with similar prevalence rates in the centres studied. There is considerable overlap b...

BACKGROUND Helicobacter pylori is the most common chronic bacterial infection, and a significant aetiological factor in acid peptic diseases and gastric cancer. Dyspepsia is a common gastrointestinal disorder, and the most common indication for gastroscopy. Detection of this organism during endoscopy has become standard clinical practice. We determine the prevalence of H. pylori infection among...

The clinical outcome of Helicobacter pylori infection has been particularly associated with virulence genotypes. These genotypes are useful as molecular markers in the identification of patients that are infected and at high risk for developing more severe gastric pathologies. Our main objective was to determine the prevalence of virulence genotypes cagA, vacA, iceA and babA2 of H. pylori, in p...

OBJECTIVE Dyspepsia usually presents first in primary care. There are many reasons for referral including urgent problems (for example, haematemesis and melaena), treatment failure, or to exclude serious pathology. Referral will change the population characteristics of primary and secondary care dyspeptics. Many of the guidelines for primary care dyspepsia, however, are based on secondary care ...

Functional dyspepsia (FD) is the most common cause of dyspeptic symptoms. It refers to a heterogeneous group of symptoms located in the upper abdomen. The prevalence of dyspepsia is variable in different populations and is related to the different definitions of dyspepsia as inclusion criterias, variation in survey population and environmental factors. Epidemiologically some risk factors have b...

Dyspepsia is common in the general population, and despite a paucity of data, smoking, alcohol, and analgesics are believed to be important risk factors. The role of these environmental factors in subjects with uninvestigated dyspepsia was evaluated in a representative population sample. An age and gender stratified random sample of residents of Olmsted County, Minnesota, aged 20 to 64 years wa...
