BACKGROUND New methods are needed to detect precancerous lesions in lung tissue. We conducted a study to determine the utility of LIFE (laser-induced fluorescence emission) autofluorescence bronchoscopy for the detection of squamous metaplasia and dysplasia in current and former smokers. METHODS In this prospective, single-center study, 53 participants underwent standard white-light bronchosc...

BACKGROUND Systematic flexible bronchoscopy is advocated in the initial management of childhood pulmonary tuberculosis. METHODS Our aim was to describe and to compare the systematic flexible bronchoscopy findings of 53 children (6.5 + or - 4.4 years; 52.8% boys) with active pulmonary tuberculosis to their initial clinical and radiological (chest x-ray, n=53; CT, n=45) features in an 11-year r...

Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...

Recent advances in bronchoscopy have led to changes in clinical diagnostics and therapeutics in pulmonary medicine. In diagnostic bronchoscopy, there have also been new developments in endobronchial ultrasound technology which may be incorporated into clinical practice in the near future. Functional bronchoscopy, which evaluates information such as airway pressure, airflow, or gas exchange, sug...

BACKGROUND Concerns remain about the safety of bronchoscopy in asthma and there are few data on the effect of this procedure on asthma control in the days or weeks following bronchoscopy. METHODS In an initial study of bronchoalveolar lavage and bronchial biopsies in asthmatic and control subjects, data on peak expiratory flow rates (PEFR) collected prospectively before and after the procedur...

Lung isolation for surgical facilitation by means of one lung ventilation (OLV) is seeing widespread use in all age groups due to increasing incidence thoracoscopy and video-assisted thoracoscopic surgery (VATS). most commonly achieved double-lumen endotracheal tubes with or without a bronchial blocker. Development intraoperative hypoxaemia (arterial oxygen saturation <90%) caused OLV known haz...

BACKGROUND Bronchoscopy is a technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. This study was performed to determine the complications of bronchoscopy in a tertiary health-care center. MATERIALS AND METHODS This study had as descriptive cross sectional design. Four hundred adult patients between 16 to 85 years, who underwent bronchoscopy with a same m...

INTRODUCTION Infantile hemangiomas of the airway are diagnosed at bronchoscopy as part of the investigation of stridor or other respiratory symptoms. Here, we present three-dimensional computed tomography (3D-CT)/bronchoscopy findings of submucosal subglottic hemangioma missed at bronchoscopy. CASE PRESENTATION We report on the clinical usefulness of 3D-CT/bronchoscopy as the primary diagnost...

Introduction: Demyelination is one of the main causes of neurological disability. It is the end product of numerous pathological processes, multiple sclerosis (MS) being the most common cause. More than 70% of the MS patients suffer from optic disturbances. This disease commonly affects the optic pathway, particularly the optic nerves and chiasm. Several attempts have been made to produce a ...

  Background :There is not any data available about the effect of high bar pressure condition on intracranial pressure. In this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated.   Methods : Twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. Only one perso...
