Chest radiography (CXR) continues to be the most frequently performed imaging examination worldwide, yet it remains prone to frequent errors in interpretation. These pose potential adverse consequences to patients and are a leading motivation for medical malpractice lawsuits. ⋯ The medicolegal implications of such errors are explained. Awareness of commonly missed CXR findings, their causes, and their consequences are important in developing approaches to reduce and mitigate these errors.

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) considers blood eosinophil counts < 100 cells/μL (BEC≤100) in people with COPD to predict poor inhaled corticosteroid (ICS) responsiveness. However, the BEC≤100 phenotype is inadequately characterized, especially in advanced COPD. ⋯ gov.

Septic shock is defined by the need for vasopressor agents to correct hypotension and lactic acidosis resulting from infection, with 30%-40% case fatality rates. The care of patients with worsening septic shock involves multiple treatment decisions involving vasopressor choices and adjunctive treatments. In this edition of "How I Do It", we provide a case-based discussion of common clinical decisions regarding choice of first-line vasopressor, BP targets, route of vasopressor delivery, use of secondary vasopressors, and adjunctive medications. We also consider diagnostic approaches, treatment, and monitoring strategies for the patient with worsening shock, as well as approaches to difficult weaning of vasopressors.

Review Historical Article
The Science of Sleep in Medieval Arabic Medicine: Part 1: Ibn Sīnā's Pneumatic Paradigm.
Modern sleep specialists are taught that, before the twentieth century, sleep was universally classified as a passive phenomenon with minimal to no brain activity. However, these assertions are made on the basis of particular readings and reconstructions of the history of sleep, using Western European medical works and ignoring works composed in other parts of the world. ⋯ Avicenna, d. 1037) onward. Building on the earlier Greek medical tradition, Ibn Sīnā provided a new pneumatic understanding of sleep that allowed him to explain previously recorded phenomena associated with sleep, while providing a way to capture how certain parts of the brain (and body) can even increase their activities during sleep.

Multicenter Study
Diagnosing non-small cell lung cancer by exhaled-breath profiling using an electronic nose: a multicentre validation study.
Despite the potential of exhaled breath analysis of volatile organic compounds to diagnose lung cancer, clinical implementation has not been realized, partly due to the lack of validation studies. ⋯ The Netherlands Trial Register; No.: NL7025; URL: https://trialregister.nl/trial/7025.
