Eosinophilic esophagitis (EoE) is an emerging chronic esophageal disease. Despite the increasing diagnosis of EoE globally, the causes of EoE and other esophageal eosinophilic disorders are not clearly understood. EoE pathology includes accumulation of inflammatory cells (e.g., eosinophils, mast cells), characteristic endoscopic features (e.g., furrows, the formation of fine concentric mucosal ...

Esophageal carcinoma is the eighth most common cancer, and the sixth most common cause of cancer-related deaths worldwide [1]. Esophageal carcinomas in developing nations account for more than 80% of the total cases and deaths [1]. Esophageal cancer can arise as esophageal squamous cell carcinoma (ESCC) or esophageal adenocarcinoma (EAC), which have distinct etiological and pathological charact...

......................................... Received: 03-07-14 Accepted: 02-02-15 Abstract The introduction of high-resolution esophageal manometry allowed physicians to identify both previously unidentified normal esophageal functions and patterns and various abnormalities. The creation of new charts of pressure patterns and the topography of esophageal pressure has led to the development of new...

OBJECTIVES Data on management of esophageal narrowing related to eosinophilic esophagitis (EoE) in children are scanty. The aim of the present study is to assess the safety and effectiveness of esophageal dilation in pediatric EoE from the largest case series to date. METHODS Children diagnosed with EoE during 2004 to 2015 were reviewed for the presence of esophageal narrowing. Esophageal nar...

Chagas' disease causes degeneration and reduction of the number of intrinsic neurons of the esophageal myenteric plexus, with consequent absent or partial lower esophageal sphincter relaxation and loss of peristalsis in the esophageal body. The impairment of esophageal motility is seen mainly in the distal smooth muscle region. There is no study about esophageal striated muscle contractions in ...

Objective: Atrio-esophageal fistula is an infrequent but devastating complication of catheter-based ablation of atrial fibrillation (AF). Thermal esophageal injury may be the precursor of atrio-esophageal fistula. Here, we evaluated the role of esophageal temperature monitoring in preventing thermal esophageal injury during pulmonary vein isolation for AF with radiofrequency energy. Methods: In...

esophageal perforation continues to be a difficult diagnostic and management problem. recommendations regarding treatment remain controversial. 17 patients with perforation of the esophagus were retrospectively reviewed at the thoracic surgery unit of imam khomeini hospital between 1981 and 1992. the majority of the injuries involved the thoracic esophagus (10 or 59%), followed by the cervical ...

Human Dachshund homologue 1 (DACH1) is a major component of the Retinal Determination Gene Network. Loss of DACH1 expression was found in breast, prostate, lung, endometrial, colorectal and hepatocellular carcinoma. To explore the expression, regulation and function of DACH1 in human esophageal cancer, 11 esophageal cancer cell lines, 10 cases of normal esophageal mucosa, 51 cases of different ...

Esophageal pain that manifests as heartburn or chest pain, is a prevalent problem. Esophageal chest pain is most often caused by gastroesophageal reflux disease (GERD), but can also result from inflammatory processes, infections involving the esophagus, and contractions of the esophageal muscle. The mechanisms and pathways of esophageal chest pain are poorly understood. Vagal and spinal afferen...

It has recently been demonstrated that acid-induced esophageal mucosal injury leads to esophageal shortening, raising the possibility that reflux esophagitis per se may contribute to the development of hiatal hernia. The aim of the present study was to determine whether mast cell-derived mediators are involved in this acid-induced esophageal shortening. Changes in esophageal length were continu...
