Primary tracheal mucosa-associated lymphoid tissue (MALT) lymphoma is extremely rare. We report a 49-year-old female patient with the complaint of dyspnea. Fiberoptic bronchoscopy showed polypoid, variable-sized and irregular nodules causing narrowing of the tracheal lumen from the proximal trachea to the left main bronchus. Because of severe stenosis in the airway and the severity of symptoms,...

The apical extracellular matrix plays a central role in epithelial tube morphogenesis. In the Drosophila tracheal system, Serpentine (Serp), a secreted chitin deacetylase expressed by the tracheal cells plays a key role in regulating tube length. Here, we show that the fly fat body, which is functionally equivalent to the mammalian liver, also contributes to tracheal morphogenesis. Serp was exp...

OBJECTIVES/HYPOTHESIS Currently available silicone and metallic stents for tracheal stenosis are associated with problems of granulations, mucus trapping, and difficult removals. Our aim was to develop a novel bioabsorbable tracheal stent with mitomycin C (MMC) drug elution to circumvent such problems. STUDY DESIGN A randomized animal study. METHODS Twenty-five rabbits were randomly assigne...

Free full text available from www.ijccm.org A b st ra ct We present three cases of iatrogenic tracheal injury. Two patients suffered acute tracheal injuries during anesthesia/surgery, one was managed surgically and the other conservatively. The third case is a delayed tracheal injury presenting as a fistula. The reasons for surgical vs conservative management of tracheal injuries and preventive...

We present a case of problematic tracheal intubation in an adult patient with an unrecognized tracheal bronchus. Immediately after tracheal intubation and position change to prone, bilateral breath sounds were almost absent, and there was a diminished tidal volume. In order to resolve the ventilatory difficulty, the wire-reinforced tube was replaced with a conventional tube, and proper position...

The Drosophila tracheal system consists of a stereotyped network of epithelial tubes formed by several tracheal cell types. By the end of embryogenesis, when the general branching pattern is established, some specialised tracheal cells then mediate branch fusion while others extend fine terminal branches. Here evidence is presented that the Notch signalling pathway acts directly in the tracheal...

We report that the region-specific homeotic gene spalt affects the Drosophila tracheal system at two different stages of embryonic development. Both lack-of-function and gain-of-function experiments show that blastodermal spalt activity restricts tracheal development to 10 bilaterally positioned pairs of tracheal placodes in the trunk region by repressing placode formation in parasegments 2, 3 ...

Introduction: General anesthesia is the most common technique for performance of various surgical procedures. Thiopental is the most common anesthetic agent for intravenous induction. Since the introduction of propofol as an anesthetic agent, its use has increased progressively and has become the drug of choice for induction of anesthesia in several conditions. The aims of this study were com...

We report a case of tracheal adenoma presenting as hemoptysis and reversible airflow obstruction in an ex-smoker. A questionable defect in the tracheal air shadow on a posteroanterior chest radiograph was shown on CT to be a pedunculated, mid-tracheal tumor. Two-stage bronchoscopic laser resection resulted in an apparently normal tracheal mucosa. Results of postresection spirometry were normal.
