INTRODUCTION Lung cancer patients receiving radiotherapy present with acute esophagitis and chronic fibrosis, as a result of radiation injury to esophageal tissues. We have shown that soy isoflavones alleviate pneumonitis and fibrosis caused by radiation toxicity to normal lung. The effect of soy isoflavones on esophagitis histopathological changes induced by radiation was investigated. METHO...

Introduction: Esophagitis is one of the main causes of swallowing dysfunction after radiation therapy (RT) for head and neck cancer (HNC).It significantly affects patients’ quality of life as well as having a potentially negative impact on their long term survival. However, little has been investigated on the dose-response and normal tissue complication probability (NTCP) of es...

Esophagitis dissecans superficialis and eosinophilic esophagitis are distinct esophageal pathologies with characteristic clinical and histologic findings. Esophagitis dissecans superficialis is a rare finding on endoscopy consisting of the peeling of large fragments of esophageal mucosa. Histology shows sloughing of the epithelium and parakeratosis. Eosinophilic esophagitis is an allergic disea...

Objective The risk factors associated with severe erosive esophagitis are not well defined in Japan. We aimed to evaluate the risk factors associated with the endoscopic severity of esophageal mucosal injury. Methods Eighty consecutive Japanese patients with severe erosive esophagitis [Los Angeles (LA) classification grade C or D] who had undergone upper endoscopies in the Gastroenterology Divi...

BACKGROUND It is well known that cytomegalovirus esophagitis occurs in immunosuppressed patients. However, few reports have described cytomegalovirus esophagitis occurring during chemoradiotherapy for esophageal cancer. CASE PRESENTATION We report two cases of patients with cytomegalovirus esophagitis that developed during chemoradiotherapy for esophageal cancer. Cytomegalovirus esophagitis w...

BACKGROUND/AIMS Although several studies have suggested overlaps between gastroesophageal reflux symptom and irritable bowel syndrome (IBS), the studies for the association between erosive esophagitis and IBS are rare. The aim of this study was to evaluate the association among IBS, non-erosive reflux disease (NERD), and erosive esophagitis. METHODS A total of 2,769 participants completed que...

BACKGROUND/AIMS Researches on the potential risk factors for the development of erosive esophagitis have been conducted extensively, however, the results are conflicting. The aim of this multicenter study was to identify the prevalence rate and risk factors of erosive esophagitis and their interactions with residency status. METHODS A total of 4,023 eligible subjects at 8 tertiary health care...

OBJECTIVE To describe the clinical picture, test results, and clinical evolution of patients with cerebral palsy associated with diagnosis of eosinophilic esophagitis, monitored at tertiary centre. METHODS Cross-sectional, retrospective and descriptive study that evaluated the medical records data of pediatric patients with diagnosis of cerebral palsy and eosinophilic esophagitis in a tertiar...

BACKGROUND/AIMS The role of Helicobacter pylori in gastroesophageal reflux disease remains still controversial and the effect of the organism on severity of reflux esophagitis have been rarely issued. The aim of this study was to investigate the relationship between H. pylori infection and reflux esophagitis, and especially the severity of reflux esophagitis. METHODS We performed a cross-sect...

An epidemiologic survey among 538 young persons between 15 and 26 years of age in a high-risk area for esophageal cancer in the People's Republic of China revealed a high prevalence of esophagitis. Histologically confirmed very mild, mild, and moderate esophagitis was observed in 31.6%, 10.7%, and 1.1% of 354 male and 30.4%, 4.3%, and 1.1% of 184 female subjects. The prevalence of micronuclei i...
