Bronchial or Laryngeal Obstruction Induced by Exercise?
A child suspected of exercise-induced laryngeal obstruction and asthma is examined by laryngoscopy and respiratory resistance (Rrs) after exercise challenge. Immediately at exercise cessation, the visualized adduction of the larynx in inspiration is reflected in a paroxystic increase in Rrs. While normal breathing has apparently resumed later on during recovery from exercise, the pattern of Rrs...
متن کاملHeredity of supraglottic exercise-induced laryngeal obstruction
Respiratory symptoms on exertion, such as shortness of breath and wheezing, are commonly associated with asthma, but might also arise from the larynx [1–3]. In recent years, the emergence of exercise laryngoscopy [4] has led to a better understanding of laryngeal movement during exercise, and inspiratory supraglottic collapse on exertion has been established as a common cause of exertional brea...
متن کاملPrevalence of exercise-induced bronchoconstriction and exercise-induced laryngeal obstruction in a general adolescent population.
BACKGROUND Exercise-induced respiratory symptoms are common among adolescents. Exercise is a known stimulus for transient narrowing of the airways, such as exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (EILO). Our aim was to investigate the prevalence of EIB and EILO in a general population of adolescents. METHODS In this cross-sectional study, a questi...
متن کاملThe Significance of BODE (BMI, Obstruction, Dyspnea, Exercise) Index in Patients with Mustard Lung
Introduction: Chronic Obstructive Pulmonary Disease (COPD) secondary to sulfur mustard exposure, known as mustard lung, is an important late pulmonary complication. The BODE (Body mass index, Obstruction, Dyspnea, and Exercise) index has been established as a valuable tool for determining the adverse consequences of COPD. The aim of this study was to evaluate the role of the BODE index in pat...
