This study confirms the existence of the ‘bulla-point’, a sonographic sign echoing the lung-point associated with pneumothorax. Other signs of pneumothorax such as absent lung sliding or barcode sign are also prevalent in bullous emphysema, especially in patients with high pulmonary distension or in apical regions.

Three-dimensional imaging (3D-image) can quantitatively measure disease extent and volume loss in patients with systemic sclerosis–related interstitial lung disease (SSc-ILD). Volume loss and disease extent were associated with disease progression. The application of 3D-image analyses can help determine disease severity and mortality risk in patients with SSc-ILD.

Patients with progressive ILD often experience exertional desaturation without resting hypoxemia. Among 86 ILD patients, 58.1% responded to oxygen therapy, with these patients showing higher mPAP and differences in cardiovascular and gas exchange parameters. Logistic regression identified mPAP > 20 mmHg as a possible biomarker predicting the response to oxygen therapy.

Vaping is an epidemic worldwide with a new life-threatening diagnosis of EVALI affecting otherwise healthy adolescents and young adults. We report the comprehensive diagnostic evaluation and complications of over 100 adolescent and young adult patients with pulmonary symptoms who vape.
