OBJECTIVE To review the presentation and natural history of children with vascular rings and present management guidelines. METHODS Retrospective study of tertiary care pediatric medical center charts from 1991 to 2002. RESULTS There were 37 males and 27 females with a diagnosis of vascular rings. At presentation, 91% of patients had airway symptoms and 47% had esophageal symptoms. Airway s...

Aorta eddy is one of the most important parameters of aorta. The incidence of arteriosclerosis can affect the characteristics of eddy current. In this study, we applied trans-esophageal echocardiography to compare aortic vortex parameters between cerebral apoplexy patients (n=102) and normal controls (n=20). Cardiac ultrasound (time resolution=15.4 ± 3.7 milliseconds, 60-80 frames/cardiac cycle...

The literature review focuses on the current understanding of visceral hypersensitivity mechanisms in esophagus. Mechanisms peripheral and central sensitization their relation to heartburn symptoms are covered detail. Diagnostic criteria algorithms for non-erosive reflux disease, functional heartburn, esophagus based pH-impedance testing high-resolution esophageal manometry data presented.

Hypercontractile esophagus (nicknamed jackhammer esophagus) is a recently defined disease within the esophageal motility disorders classification. Responses to treatments for jackhammer esophagus have been inconsistent in previous trials, possibly due to its heterogeneous manifestation. Thus, we reviewed 10 patients diagnosed with jackhammer esophagus and compared their clinical and manometric ...

Gastroesophageal reflux disease is a widespread chronic in which stomach or duodenal contents rise up into the esophagus. Esophageal spasm and achalasia cardia are poorly studied disorders associated with impaired neuromuscular impulse transmission motor discoordination of esophagus, manifested by chest pain dysphagia. The article presents clinical case young patient gastroesophageal history at...

background : numerous epidemiologic studies have shown that esophagus cancer is more common in areas with grains containing mycotoxin such as fumonisin b1 (fb1). the aim of this research is to study the effect of long- and short-term of esophagus tissue to fb1 orally administered in animal model. materials and methods : forty-four female mice have been divided in two short- and long-term groups...

cell free dna (cfdna) is a genetic biomarker that is present in serum or plasma in high concentration in many types of cancer. identification of circu-lating cancer related dna molecules in serum or plasma is a non-invasive tool for early diagnosis and prognosis in many cancer patients. for this review, study selection and data extraction were performed by the authors. detection of point mutati...

background: esophageal cancer is the sixth cause of death in the world, there was a lack of population‑based information on the trend and incidence rate of esophagus cancer, so this study aimed to determine the incidence and pathological changes of esophagus cancer in iran. methods: in this study, data were extracted from annual cancer registry reports of iranian ministry of health between 2003...
