Pseudomembranous aspergillus tracheobronchitis superimposed on post-tuberculosis tracheal stenosis has not been previously reported. In the patient described in this case report, the airway obstruction was worsened by aspergillus infection which responded to antifungal therapy and debridement of pseudomembranous tissues by rigid bronchoscopic procedures. A(More)
OBJECTIVES Severity of airway narrowing is relevant to management decision-making processes in patients with laryngotracheal stenosis. Airway lumen is frequently assessed subjectively based on still images obtained during airway examinations or objectively using image analysis software applied to radiological or bronchoscopic images. The purpose of this(More)
BACKGROUND Electromagnetic navigation bronchoscopy (ENB) procedures allow physicians to access peripheral lung lesions beyond the reach of conventional bronchoscopy. However, published research is primarily limited to small, single-center studies using previous-generation ENB software. The impact of user experience, patient factors, and lesion/procedural(More)
The purpose of this article is to provide an update on methods for palliating symptoms in patients with histologically benign and malignant central airway obstruction. We review the published literature within the past decade on postintubation, posttracheostomy, and TB- and transplant-related airway strictures; tracheobronchomalacia; and malignant airway(More)
BACKGROUND AND OBJECTIVE Patients with expiratory central airway collapse present with various symptoms, aetiologies, morphologies, extent and severity of airway collapse. The aim of this study was to delineate a multidimensional classification system and common language for evaluating patients with expiratory central airway collapse. METHODS The(More)
Differences in central airway wall structure in patients with various forms of expiratory central airway collapse can be identified by endobronchial ultrasound using a 20 MHz radial probe. In tracheobronchomalacia due to relapsing polychondritis, the cartilage is thick and irregular while the membranous portion is normal. In malacia due to chronic(More)
Tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC) are both dynamic forms of central airway obstruction characterized by a decrease of >/=50% in the cross-sectional area of the tracheobronchial lumen. The differences between these two entities, however, are not uniformly accepted in the medical community. While TBM is characterized by(More)
BACKGROUND Silicone stent insertion is an alternative treatment for expiratory central airway collapse. This study evaluates the complications (mucus plugging, migration, and granulation tissue) associated with stenting in patients who failed medical therapy and were not surgical candidates. METHODS Chart review from 15 consecutive patients treated by(More)
Fractals are mathematical constructs that show self-similarity over a range of scales and non-integer (fractal) dimensions. Owing to these properties, fractal geometry can be used to efficiently estimate the geometrical complexity, and the irregularity of shapes and patterns observed in lung tumour growth (over space or time), whereas the use of traditional(More)
BACKGROUND These guidelines are an update of the evidence-based recommendations for follow-up and surveillance of patients after curative-intent therapy for lung cancer. Particular updates pertain to whether imaging studies, health-related quality-of-life (HRQOL) measures, tumor markers, and bronchoscopy improve outcomes after curative-intent therapy. (More)
