Chronic Cough Due to Stable Chronic Bronchitis: CHEST Expert Panel Report.
Chronic cough due to chronic bronchitis (CB) causes significant impairment in quality of life, and effective treatment strategies are needed. We conducted a systematic review on the management of chronic cough due to CB to update the recommendations and suggestions of the American College of Chest Physicians (CHEST) 2006 guideline on this topic. ⋯ The evidence supporting the management of chronic cough due to CB is limited overall and of low quality. This article provides guidance on treatment by presenting suggestions based on the best currently available evidence and identifies gaps in our knowledge and areas for future research.

OSA is a highly prevalent sleep disorder, and subjective excessive daytime sleepiness (EDS) is the cardinal symptom for which many individuals seek medical advice. Positive airway pressure (PAP) devices, first-line treatment for OSA, eliminates EDS in most patients. However, a subset of patients suffers from persistent EDS despite adherence to therapy. ⋯ Solriamfetol has undergone randomized controlled trials for treatment of EDS associated with both OSA and narcolepsy, exhibiting robust efficacy. Solriamfetol is renally excreted, with no known drug interactions. Pitolisant, which is nonscheduled, has undergone multiple RCTs in narcolepsy, showing improvement in subjective and objective EDS and one OSA trial showing improvement in subjective EDS.

A 23-year-old man arrives at the ED with a 3-week history of dyspnea, dry cough, fevers, and night sweats. Two weeks previously, he was evaluated in an outpatient clinic and given a course of azithromycin for presumed infectious pneumonia. His symptoms did not improve, and he was seen 1 week later in an urgent care center and given a prescription for doxycycline, which he has been taking without improvement. ⋯ Urine toxicology screen is positive for tetrahydrocannabinol (THC). Asked specifically about vaping and e-cigarette use, he reports that he recently began using THC "carts" that his friend gets from an unknown supplier. What is the diagnosis and what additional steps are necessary to confirm it? Is bronchoscopy indicated?
