history of medicine is a treasure of interesting experiences of humankind to treat diseases. traditional medicine is a major part of this long history. world health organization (who) encourages all countries to extend their complementary and traditional medicines and support trained practitioners in this field. this strategy can lead to finding new treatments and opening new horizons to the he...

In eosinophilic esophagitis (EoE), diagnostic tests aid in the identification of pathophysiologic consequences and accurate detection of the disease. The EoE Endoscopic Reference Score (EREFS) classifies and grades the severity of the five major endoscopically identified esophageal features of EoE (edema, rings, exudates, furrows and strictures). The EREFS may be useful in the evaluation of dis...

The relationship between Helicobacter pylori (Hp) gastritis and gastroesophageal reflux disease (GERD) remains controversial. The aim was to investigate the association between Hp infection and gastroesophageal reflux (GER) and the impact of Hp eradication on esophageal acid exposure and motility in adolescents and young adults with Hp gastritis and GERD. Sixty-four patients with symptoms sugge...

BACKGROUND Barrett's mucosa is the precursor of esophageal adenocarcinoma. The molecular mechanisms behind Barrett's carcinogenesis are largely unknown. Experimental models of longstanding esophageal reflux of duodenal-gastric contents may provide important information on the biological sequence of the Barrett's oncogenesis. METHODS The expression of CDX2 hox-gene product was assessed in a ra...

OBJECTIVE The purpose of this study was to evaluate the changes in esophageal physiology that are produced after laparoscopic surgery in patients with gastroesophageal reflux disease (GERD). METHODS From May 1996 until January 2000, 13 patients with GERD underwent antireflux laparoscopic surgery. In 8 patients, preoperative manometric studies showed motility disorders characterized by a decre...

VV Gastroesophageal reflux disease (GERD) results from the failure of the lower esophageal sphincter to keep acid and other fluids in the stomach. This incompetency is commonly caused by the presence of a hiatal hernia, although a person can have pathologic reflux without a hiatal hernia and, conversely, can have no pathologic reflux even in the presence of a hiatal hernia. Most reflux is actua...

An increase in intraesophageal pressure during transient lower esophageal sphincter (LES) relaxation [referred to as common cavity (CC) pressure] is thought to be a marker of gastroesophageal reflux (GER). Multiluminal impedance (MII) measurement is a sensitive marker of reflux entry into the esophagus during GER. We recorded GER using esophageal pressure, pH, impedance, and intraluminal ultras...

BACKGROUND Esophago-gastroduodenal anastomosis with rats mimics the development of human Barrett's esophagus and esophageal adenocarcinoma by introducing mixed reflux of gastric and duodenal contents into the esophagus. However, use of this rat model for mechanistic and chemopreventive studies is limited due to lack of genetically modified rat strains. Therefore, a mouse model of esophageal ade...

Transient receptor potential vanilloid-1 (TRPV1) receptor and proteinase-activated receptor 2 (PAR2) have been implicated in the mechanism of acid-induced inflammation in gastroesophageal reflux disease (GERD). We aimed to evaluate TRPV1 and PAR2 mRNA expression levels in the GERD patients and their relationship with endoscopic findings and reflux symptoms.Sixteen healthy controls, 45 patients ...
