Tracheal research covers two main areas of interest: tracheal reconstruction and tracheal fixation. Tracheal reconstructions are aimed at rearranging or replacing parts of the tracheal tissue using implantation and transplantation techniques. The indications for tracheal reconstruction are numerous: obstructing tracheal tumors, trauma, post-intubation tissue reactions, etc. Although in the past...

The elaborate branching pattern of the Drosophila tracheal system originates from ten tracheal placodes on both sides of the embryo, each consisting of about 80 cells. Simultaneous cell migration from each tracheal pit in six different directions gives rise to the stereotyped branching pattern. Each branch contains a fixed number of cells. Previous work has shown that in the dorsoventral axis, ...

Tracheal transplantation remains a challenge for General Thoracic Surgery. A large number of surgical techniques and implantable devices has been tested with poor results. In spite of that, some recent findings on tracheal revascularization and graft epithelial replacement have renewed the interest on tracheal transplantation, with special attention to graft bioengineering. However, in order to...

Abstract Background Caudal tracheal stent migration can be potentially life threatening by causing distal luminal obstruction. We present a rare double hitch stitch procedure (for prevention of stent), which is an external fixation technique in case tracheoesophageal fistula with and esophageal self-expandable metallic (SEMS). Case presentation A 50-year-old male patient who presented cough dys...

We report a case of tracheal rupture in an 84-yr-old patient after tracheal intubation. The aetiology and treatment are discussed and the recent literature is reviewed.

Background & aim: Health system responsiveness (HSR) addresses patient`s non-medical and logical expectations. Various working conditions lead to different levels of responsiveness. No research has been conducted on the responsiveness in the obstetrics and gynecology departments. Therefore, this study was carried out to measure health system responsiveness in obstetric...

Key points † Optimizing tracheal sealing is of clinical interest: fluid leakage past the tube cuff plays an important role in the pathogenesis of VAP. † Tapered shaped tube cuff offering a sealing zone with reduced folds and channels is a new strategy to minimize fluid leakage past the tracheal tube cuff. † Tracheal tube cuffs made from PVC show much more and faster fluid leakage than cuffs mad...

Tracheal diameter can be assessed from a thoracic radiograph, with assessment of tracheal diameter in dogs based on ratios between tracheal diameter and a skeletal measurement. Reference intervals are not, however, available for the cat. Tracheal narrowing may cause significant clinical problems, although tracheal hypoplasia in dogs may be clinically silent, and is rarely reported in cats (both...

  Background: Responsiveness is one of the three main goals of the health system introduced by World Health Organization. This study aimed at examining health system responsiveness after Health Sector Evolution Plan in Kermanshah, Western Iran.   Methods: A sample of 335 hospitalized patients was selected using proportionate allocation to population size method in the city of Kermanshah (Ira...
