purpose: to evaluate the outcomes of keratorefractive surgery for correction of postkeratoplasty astigmatism in keratoconus. methods: in this retrospective study, surgical records of 45 eyes of 45 patients that underwent relaxing incisions with or without compressive sutures were evaluated. the minimum interval between complete suture removal and operation was 1 month. location and extent of in...

OBJECTIVES To evaluate the histological changes of tracheal cartilage and epithelium caused by tracheal occlusion at different gestational ages in a fetal rat model. METHODS Rat fetuses were divided into two groups: a) External control, composed of non-operated rats, and b) Interventional group, composed of rats operated upon on gestational day 18.5 (term = 22 days), divided into triads: 1) T...

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.

Abstract Background Giant inguinal hernia (GIH), defined as a descending below the inner-thigh midpoint in upright position, is rare. Case reports describe techniques which abdominal cavity prepared and care taken to prevent compartment syndrome (ACS). Our aim was analyze review our experience with GIH repair. Methods Retrospective single-institution, case-control, study included adults who und...
