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 th...

BACKGROUND AND OBJECTIVES Injuries of tracheal mucosa in contact with tracheal tube cuff is a function of cuff pressure and exposure time. This study aimed at analyzing injuries of tracheal mucosa in contact with tracheal tube cuff inflated to reach "seal" pressure or limit 25 cmH2O pressure, below critical 30 cmH2O, to prevent tracheal damage. METHODS This study involved 16 dogs submitted to...

â  background treatment of hemorrhoid disease is one of the most challenging fields in general surgery in which different methods are used to treat this condition. in this study, we compared the manometric and clinical results of three treatment methods for hemorrhoids. me t hod s a total of 150 patients with symptomatic grades ii or iii internal hemorrhoids were randomly assigned to three grou...

background: the present study was conducted in order to evaluate the effects of bilateral uterine artery ligation (bual) on the ovarian follicular fate, and alterations in carbohydrate, lipid, lipase and serum levels of f9sh, lh, prolactin, estrogen and progesterone. methods: twenty-four mature female rabbits divided into two test and control-sham groups. the animals underwent ovariohystrectomy...

objective(s): electrical inhomogeneity between ischemic and non ischemic myocardium is the basis of arrhythmia which occurs following coronary artery occlusion. the leakage of potassium from the ischemic region to the non ischemic region is very effective in the generation of these arrhythmias. the aim of this study is to research the effect of atp-dependent potassium (katp) channel blocker (gl...

BACKGROUND Tracheal necrosis is a severe complication of total pharyngolaryngectomy (TPL). The purpose of this retrospective study was to identify risk factors for tracheal necrosis after TPL. METHODS We performed a retrospective chart review of 177 patients who had undergone TPL. The preoperative, operative, and postoperative variables were examined, and possible risk factors for tracheal ne...

Difficulty of tracheal intubation is caused by many reasons and among them tracheal rupture is an infrequent factor. Tracheal rupture leads to higher mortality and poorer prognosis especial for closed tracheal rupture which is hard to early diagnose and is generally fatal. We described a case of a 34-year-old narcose man after a car accident that accepted twice unsuccessful tracheal intubation ...

materials and methods a number of 100 patients with imr, normal karyotypes and negative fragile-x and metabolic tests were screened for subtelomeric abnormalities using mlpa technique. results nine of 100 patients showed subtelomeric abnormalities with at least one of the two mlpa kits. deletion in a single region was found in 3 patients, and in two different subtelomeric regions in 1 patient. ...
