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 cerv...

Open wound managment after perforated appendicitis has been a common practice but recently, primary closure has been advocated to reduce costs and morbidity. For comparing delayed closures against primary closure with vacuum drainage, a randomized experimental study was designed. in Kerman. Sixty patients with perforated appendicitis divided randomly in two groups and evaluated on day of discha...

Digital Elevation Models (DEMs) are used to estimate different morphologies, analysis of river profile, delineating drainage basin and drainage pattern associated with lithological and structural changes. The study area is Maroon River located in Khuzestan Province, Iran. In this study geomorphometric analysis based on DEM carried out to understand Maroon river uplift rate and tectonic- erosion...

One of the most important factors for appropriate performance of subsurface drainage systems is having adequate discharge for drains. For this purpose, knowledge about effect of drainage parameters change on drain discharge is essential in subsurface drainage systems. In this article, using change all of the drainage parameters by EnDrain software, changes of drains discharge has been investiga...

AIM The aim is to investigate, in relation to the volume of blood drained, which type drainage to use after thyroidectomy natural drainage or negative drainage. MATERIAL OF STUDY 141 patients who underwent total thyroidectomy for multinodular thyroid disease between 22 November 2012 and 7 November 2013 were included in the present study. For the 141 patients a randomized method was used with ...

the present study carried out to identify neo tectonic activity of the gorgan river basin in golestan province, in north of eastern alborz range is investigated by four geomorphic indices including the stream– gradient index (sl), drainage basin asymmetry (af), reveres symmetry of topography (t) and mountain front sinuosity (smf). result from the analysis is accumulated and expressed as an in...
