Boesch RP, et al. - This trial scrutinized the prevalence of anatomic, infectious, and inflammatory disease in children undergoing flexible bronchoscopy for wheezing or poorly controlled asthma. The transnasal flexible bronchoscopy reported a high yield in children with recurrent, persistent, or atypical wheezing and those with poorly controlled asthma. Laryngeal cleft possibly presented with a considerably high prevalence which necessitated specific assessment in the study cohort.
