conclusions it seems that severe pah aggravates the rv function more severely. results significant tricuspid regurgitation was more prevalent in the pah group than in the ps group (61% vs. 18.5%; p < 0.001). the abnormalities in the rv myocardial performance index, rv areas, and rv fractional area change were significantly more robust in the pah group (all ps < 0.05) despite the higher net rv s...

a 12 year old child with liodgkin's disease and having received 12 courses of chemotherapy, was referred to thin center with esophageal obstruction. after having performed the necessary investigations, a decision was made to undertake surgery. after surgery, the patient recovered completely and presently enjoys a heallhv life.

a case of an acute intestinal obstruction in a 64 -year - old man, due to cicatriceal stricture of tlie left colon with secondary enteroliths in colon, is presented. enteroliths in colon arc rare and it is suggested that stasis is the most important factor in their production as ihey arc. most commonly associated with an intestinal sricturc.

The aim of this study is to investigate the effects of non-Newtonian blood rheology models on the wall shear stress (WSS) distribution in a cohort of patients-specific coronary arteries. Twenty patients with diseased left anterior descending (LAD) coronary arteries (with varying degrees of stenosis severity from mild to severe) who underwent angiography and in-vivo pressure measurements were se...

  Abstract   Background: Recently, small dense low density lipoprotein (sdLDL) has been   highlighted as a new risk factor for the coronary artery disease (CAD).Small dense   LDLs are believed to be atherogenic since these particles are taken up more easily by   arterial wall. They are readily oxidized and have reduced affinity for low density   lipoprotein (LDL) receptor and increased affinity...

abstract   background: iatrogenic airway injury after endotracheal intubation and tracheotomy remains a serious clinical problem. in this study we reviewed post-intubation and traumatic tracheal stenosis in 47 patients with a special attention to the cause, hense surgical treatment of the stenosis was performed and the results compared with the literatures.   methods: since february 1995 throug...

purpose: to evaluate the effect of stenosis nature on success of silicone intubation for nasosolacrimal duct stenosis (nlds) in adults (patent nasolacrimal duct with resistance to positive-pressure irrigation) methods: an interventional case series of consecutive monocanalicular and bicanalicular silicone intubation for nasolacrimal duct stenosis in adults were reviewed. the severity of the ste...

introduction: tracheal stenosis is normally caused by trauma, infection, benign and malignant tumors, prolonged intubation or tracheostomy. the best treatment for tracheal stenosis is resection and anastomosis of trachea. yet the major surgical complication of tracheal surgery is postoperative stenosis. the goal of this paper is to study the result of tracheal stenting as a replacement therapy ...
