introduction: laryngotracheal stenosis can be caused after traumatic injuries to the neck from the subglottic larynx to the trachea. patients with laryngotracheal stenosis often need a tracheotomy and occasionally may become tracheotomy dependent. different procedures have been described for the management of these lesions. management options include techniques of endoscopic dilation, laser res...

a twenty-year-old girl was referred with tracheal stenosis (ts) which was a consequence of prolonged intubation after head injury because of previous car accident. the patient was aphasic and had normal respiration. fiberoptic bronchoscopy showed complete tracheal obstruction at second tracheal ring level. distal trachea was normal through tracheostomy tube. removal of the tracheostomy tube and...

introduction:tapia’s syndrome is a rare complication of recurrent laryngeal and hypoglossal nerve paralysis due to anesthetic airway mismanagement or malpositioning of the patient’s head during surgery. case report:here we present a case of tapia's syndrome in a 22-year-old male after corrective jaw surgery under general anesthesia, with a long period of recovery, related to airway managem...

micrornas participate in the regulation of asthma, the goal of this study is to summarize recent researches on the roles of micrornas in the pathogenesis of asthma. a review of the english medical literatures was conducted by searching pubmed for studies concerning asthma and micrornas. the results of the present study indicate that micrornas play important roles in regulating asthma immune res...

conclusions although some studies showed association between anemia and extubation failure, the current study could not confirm it. the study showed that males, regardless of the hct level, had a better extubation success rate than those of females. results there was no significant association between the level of hct concentration and extubation failure (8.9% vs. 9.2%, p = 0.507). gender and a...

Background The impact of airway obstruction of nonsmoking women caused by their husband's smoking is unclear, despite the association between environmental tobacco smoke (ETS) exposure at home and obstructive pulmonary diseases among nonsmoking women. The aim of this study was to provide evidence that ETS exposure from the husband at home has a more significant influence on the airway obstructi...

This study aimed to investigate the role of M3 acetylcholine receptor (M3-AChR) expression in airway remodeling. Additionally, we aimed to evaluate the effects of ipratropium bromide solution inhaled in an early phase of asthma on airway remodeling in ovalbumin (OVA)-sensitized and challenged mice. Thirty BALB/c mice were divided into three groups, namely, control group (saline sensitized/chall...

STATEMENT OF THE PROBLEM Individuals with cleft lip and cleft palate mostly have airway problems. Introduction of cone beam computed tomography (CBCT) and imaging software has provided the opportunity for a more precisely evaluating 3D volume of the airway. PURPOSE The purpose of this study was to analyze and compare 3D the pharyngeal airway volumes of cleft palate patients with normal indivi...

Background: Asthma is the chronic inflammation of airways characterized by eosinophilic infiltration, mucus overproduction, airway hyper-responsiveness and airway remodeling. These changes are induced mostly by cytokines which are produced by T helper (Th) 2 cells. Recently, the role of interleukin-23 (IL-23) in the pathogenesis of adultallergic asthma has been studied. Objective: To explore IL...
