Gastroesophageal reflux disease (GERD) is a global disease rapidly increasing among world population. The pathogenesis of reflux esophagitis which is considered as the early stage of GERD is complex, resulting from an imbalance between aggressive factors damaging the esophagus and a number of the
In an earlier study wherein we induced acute reflux by interrupting proton pump inhibitor (PPI) therapy in patients with reflux oesophagitis (RO) healed by PPIs, we refuted the traditional concept that RO develops as an acid burn. The present study explored our alternative hypothesis that RO results
The aim of this study was to evaluate the prevalence of hypoxia related to midazolam sedation during upper gastrointestinal endoscopy. This single blind randomized placebo control clinical trial, carried out on 180 patients who referred to endoscopy clinic at Imam Khomeini Hospital for selective
Traditionally, reflux esophagitis was assumed to develop as a caustic, chemical injury inflicted by refluxed acid. Recently, however, studies in rats and humans suggest that reflux esophagitis develops as a cytokine-mediated inflammatory injury, with hypoxia inducible factor (HIF)-2α playing a major
Tumor hypoxia causes resistance to radiation and chemotherapy. Evofosfamide (TH-302) has exhibited specific hypoxia-dependent cytotoxicity against primary acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) samples in vitro. Based on these findings, a Phase I study of evofosfamide
Reflux esophagitis damages the squamous epithelium that normally lines the esophagus, and promotes replacement of the damaged squamous lining by the intestinal metaplasia of Barrett's esophagus, the precursor of esophageal adenocarcinoma. Therefore, to prevent the development of Barrett's metaplasia
Epithelial barrier dysfunction is a significant factor in many allergic diseases, including eosinophilic esophagitis (EoE). Infiltrating leukocytes and tissue adaptations increase metabolic demands and decrease oxygen availability at barrier surfaces. Understanding of how these processes impact
Three infants with severe upper gastrointestinal hemorrhage with esophagogastroduodenoscopic (EGD) findings were reported. The underlying conditions of these infants included Down's syndrome, hypoplastic left heart, and diaphragmatic hernia. The precipitating factors were identified in all cases,
The results of a prospective assessment of cardiorespiratory changes related to anaesthesia and laparoscopic Nissen fundoplication are described in 25 children aged 1.2 to 14.3 years, weighing 9.0 to 64.0 kg. Respiratory disease or oesophagitis were present in 68% cases. During balanced inhalational
Gastroesophageal reflux (GER) is one of the most frequent symptomatic clinical disorders affecting the gastrointestinal tract of infants and children. During the past 2 decades, GER has been recognized more frequently because of an increased awareness of the condition and also because of the more
Acute leptospirosis in Europe (Weil's disease) is a rare and in more than 90% of the cases undiagnosed febrile, self-limited disease. We report the case of a 39-year-old sewerage worker, who was admitted to our hospital with fever, jaundice, pain in his calves and acute renal failure. Serology
Recent studies have demonstrated that angiogenesis and suppressed cell-mediated immunity (CMI) play a central role in the pathogenesis of malignant disease facilitating tumour growth, invasion and metastasis. In the majority of tumours, the malignant process is preceded by a pathological condition
OBJECTIVE
To analyze the risks versus benefits of esophagogastroduodenoscopy performed soon after myocardial infarction.
METHODS
We studied 200 patients who underwent endoscopy within 30 days after myocardial infarction with 200 controls matched for age, sex, and endoscopic indication who underwent
METHODS
A dog was referred for treatment after ingestion of quick-dissolve chlorine granules intended for use in a swimming pool.
RESULTS
At evaluation 18 hours after ingestion of the granules, the dog had tachypnea, signs of depression, approximately 5% dehydration, oral mucositis, and a productive
OBJECTIVE
It is important to identify optimal regimens of cisplatin-based, third-generation chemotherapy and thoracic radiotherapy for patients with unresectable, Stage III, non-small cell lung cancer.
METHODS
Patients with unresectable, Stage III non-small cell lung cancer were treated with the
