Robotic Bronchoscopy for Peripheral Pulmonary Lesion Biopsy: Evidence-Based Review of the Two Platforms.

Despite many advancements in recent years for the sampling of peripheral pulmonary lesions, the diagnostic yield remains low. Initial excitement about the current electromagnetic navigation platforms has subsided as the real-world data shows a significantly lower diagnostic sensitivity of ~70%. "CT-to-body divergence" has been identified as a major limitation of this modality. In-tandem use of the ultrathin bronchoscope and radial endobronchial ultrasound probe has yielded only comparable results, attributable to the limited peripheral reach, device maneuverability, stability, and distractors like atelectasis. As such, experts have identified three key steps in peripheral nodule sampling-navigation (to the lesion), confirmation (of the correct location), and acquisition (tissue sampling by tools). Robotic bronchoscopy (RB) is a novel innovation that aspires to improve upon these aspects and consequently, achieve a better diagnostic yield. Through this publication, we aim to review the technical aspects, safety, feasibility, and early efficacy data for this new diagnostic modality.

A 41-Year-Old Man Presenting With Shortness of Breath, Nausea, Vomiting, and Diarrhea.

CASE PRESENTATION: A 41-year-old man presented to our institution with shortness of breath for 1 day, and nausea, vomiting, and diarrhea for 10 days. He has a medical history of gastroesophageal reflux disease, migraines, and anxiety. He is a 10 pack-year former cigarette smoker and an active vaper. He quit smoking cigarettes in 2013 but reports vaping flavored nicotine from 2013 to 2018. Since 2018, he has been vaping tetrahydrocannabinol products of different flavors and brands. A few weeks prior to admission, the subject had changed the brand of his vaping product to "Cookies High Flyers" with a "Biscotti" flavor. The new product contains 1,000 mg (883 mg tetrahydrocannabinol and 117 mg cannabidiol) in a 0.04 oz cartridge. He vapes five times a day, taking two to three puffs every time. He had recently traveled to Texas and had a sick contact with his 18-month-old daughter. She recently recovered from a diarrheal illness of presumed viral origin. Prior to admission, the subject tested negative for influenza and completed outpatient antibiotic treatment, with no improvement.

Vaping epidemic in US teens: problem and solutions.

PURPOSE OF REVIEW: Over the last decade, vaping has emerged into an epidemic of alarming proportions among US teens. This review evaluates the factors leading to the rise of vaping, reasons for its striking popularity among US teens, health consequences of vaping, and measures to mitigate the vaping epidemic. RECENT FINDINGS: Contemporary research highlights the continued rise of vaping amongst US teens and explains the reasons for its popularity, such as the variety of devices, a wide range of available flavors, youth-targeted advertisements, and lack of awareness of adverse consequences from vaping. This publication highlights current research findings of health consequences of vaping, including a discussion of EVALI (e-cigarette or vaping product use-associated lung injury) and provides an update on strategies to curtail the vaping epidemic. SUMMARY: Vaping has risen to epidemic proportions amongst US teens. This poses a clear and present danger to teens' health with adverse effects ranging from acute lung injury to long-term addiction. This article summarizes key research findings that explain the reasons for the epidemic, health consequences of vaping, and provides an overview of efforts to mitigate the vaping threat to US teens.
