Review Meta Analysis
The Impact of Positive Expiratory Pressure Therapy on Hyperinflation in Patients With COPD.
Lung hyperinflation is a typical clinical feature of patients with COPD. Given the association between breathing at elevated lung volumes and the manifestation of severe debilitating symptoms, therapeutic interventions such as positive expiratory pressure (PEP) therapy and its variations (temporary, oscillatory) have been devised to mitigate lung hyperinflation. However, the efficacy of these interventions remains to be conclusively demonstrated. ⋯ In patients with COPD, the effect of PEP therapy on lung hyperinflation is unclear owing to the non-consistent change in lung hyperinflation outcomes, insufficient data, and lack of high-quality trials. Dyspnea and physical capacity might improve with PEP therapy.

Review
Late Diagnosis of Foreign Body Aspiration in Adults: Case Series and Review of the Literature.
Tracheobronchial foreign body (FB) aspiration (FBA) is a life-threatening emergency mostly observed in childhood and advanced age. With early diagnosis, the FB can be removed using bronchoscopic methods without causing irreversible damage. ⋯ The findings of the present study demonstrate that subjects tended to forget the FBA, leading to insidious respiratory system symptoms, with recurrent infections. In cases with an endobronchial mass lesion image on thorax CT, clinicians should consider the possibility of FBA. Delayed diagnosis of both organic and inorganic FB may cause granulation tissue.
