ReviewElectronic cigarettes and e-cigarette/vaping product use associated lung injury (EVALI).
Electronic cigarettes (e-cigarettes) are noncombustible tobacco products that have been promoted as safer alternatives to conventional cigarettes and beneficial tools for smoking cessation. However, e-cigarettes have been shown to produce aerosols with high concentrations of propylene glycol, glycerol, volatile organic compounds, and free radicals, which can lead to lung damage. ⋯ This rise in popularity of noncombustible products led to an outbreak of e-cigarette or vaping product use-associated lung injury (EVALI) in the fall of 2019. In this article, we review the history of e-cigarettes and its prevalence among American youth, the EVALI outbreak and clinical presentation of EVALI patients, and recent legislative efforts to regulate e-cigarette use.

Lung ultrasound (LUS), a non-invasive non-ionizing radiation tool, has become essential at the bedside in both adults and children, particularly in the critically ill. This manuscript reviews normal LUS patterns and the most important pathologies that LUS allows to diagnose. Normal LUS is represented by the pleural line, the lung-sliding and the A-lines and B-lines. ⋯ The distribution of B-lines also appears to be useful to monitor the response to antibiotics in pneumonia. However, further studies are needed to further ascertain this evidence. LUS is also useful to guide thoracocentesis.

E-cigarettes are electronic nicotine delivery systems (ENDS) which mimic tobacco smoking without the combustion of tobacco. These devices have been misleadingly marketed as "less harmful" alternatives to conventional smoking tobacco products. The e-liquid in e-cigarettes include nicotine, a humectant and other additives including flavourings, colourants, or adulterants such as bacterial and fungal products. ⋯ The presentations are diverse and clinicians should consider vaping as a possible cause of any unusual respiratory illness in patients who have a history of vaping or other use of e-cigarette-related products. Second hand exposure to e-cigarettes is also harmful through respiration and transdermal absorption. E-cigarettes have a worse acute toxicity than tobacco and their long-term toxicity is unknown, and we advocate for the immediate, most vigorous anti-vaping legislation possible.
