Article Synopsis
  • - Mediastinal lymphadenopathy can indicate various conditions, including lymphoma, and the best biopsy method currently used is transbronchial needle aspiration, which has variable effectiveness and limitations in accurately distinguishing lymphoma types.
  • - More invasive procedures like mediastinoscopy yield better diagnostic results and maintain lymph node structure for accurate classification, but they also come with a higher risk of complications.
  • - Newer techniques like core biopsy needles and cryobiopsy show promise in improving diagnostic accuracy but need further research to establish standardized practices for diagnosing lymphoma, especially since pleural effusions related to lymphoma are common.

Background: The clinical features and outcomes of mechanically ventilated patients with COVID-19 infection who develop a pneumothorax has not been rigorously described or compared to those who do not develop a pneumothorax.

Purpose: To determine the incidence, clinical characteristics, and outcomes of critically ill patients with COVID-19 infection who developed pneumothorax. In addition, we compared the clinical characteristics and outcomes of mechanically ventilated patients who developed a pneumothorax with those who did not develop a pneumothorax.

Purpose: To evaluate the utility of the forced oscillation technique (FOT) among military veterans with preserved spirometry and chronic unexplained respiratory symptoms.

Methods: 178 veterans referred for evaluation of unexplained respiratory symptoms completed pulmonary function testing and FOT. Preserved spirometry was defined as FEV/FVC, FEV and FVC ≥ 5th percentile.
