Exposure to cigarette smoke can lead to a variety of parenchymal lung diseases, including diffuse cystic lung diseases (DCLDs). Lymphangioleiomyomatosis (LAM) is the prototypical DCLD and has a characteristic appearance on high-resolution CT (HRCT). ⋯ We submit that cigarette smoke-induced small airway injury can present as DCLD on HRCT in a pattern that can mimic LAM. A detailed history of cigarette smoke exposure should be obtained in patients presenting with DCLD, and imaging features should not be used in isolation to establish a firm diagnosis of LAM.

Single omic analyses have provided some insight into the basis of lung function in children with asthma, but the underlying biologic pathways are still poorly understood. ⋯ The results of this hypothesis-generating study suggest a mechanistic basis for multiple asthma genes, including ORMDL3, and a role for lipid metabolism. They demonstrate that integrating multiple omic technologies may provide a more informative picture of asthmatic lung function biology than single omic analyses.

Brain death is a difficult concept for the public to comprehend, resulting in a reliance on alternative resources for clarity. This study aims to understand the public's perception of brain death via analysis of information on the Internet, determine the accuracy of that information, and understand how its perception affects the physician-patient relationship. ⋯ The study revealed a significant amount of inaccurate information about brain death, affecting the public's understanding of the concept of brain death and resulting in negative emotions specifically toward physicians, and the link between brain death and organ donation. The medical community can improve understanding through consistent, simplified language, dissociating brain death from organ donation, and recognizing the emotions tied to discussions of brain death.

Rapid response teams (RRTs) respond to hospitalized patients with deterioration and help determine subsequent management, including ICU admission. In such patients with sepsis and septic shock, the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) clinical criteria have a potential role in detection, risk stratification, and prognostication; however, their accuracy in comparison with the systemic inflammatory response syndrome (SIRS)-based septic shock criteria is unknown. We sought to evaluate prognostic accuracy of the Sepsis-3 criteria for in-hospital mortality among infected hospitalized patients with acute deterioration. ⋯ Hospitalized patients with deterioration from suspected infection had higher risk of in-hospital mortality if they met the Sepsis-3 septic shock criteria than the SIRS-based septic shock criteria. Therefore, use of the Sepsis-3 criteria may be preferable in the prognostication and disposition of these patients who are critically ill.

A 31-year-old woman presented to the ED with a loss of taste and smell of 2 months' duration and a frontal headache, bilateral facial numbness, photophobia, and horizontal diplopia that was worse with far vision of 2 weeks' duration. A review of systems revealed mild nausea and decreased appetite without weight loss. She denied any cardiopulmonary symptoms, specifically no cough or shortness of breath. ⋯ The patient was diagnosed with ankylosing spondylitis, for which she had been taking etanercept for several months. She consumed minimal alcohol and had no history of tobacco or drug use or recent travel. Her family history was unremarkable.
