Recently, we reported a number of key, common medications that affect the air passages in a variety of fashions. The purpose of this article is to provide a comprehensive review of the literature on the subject, including supportive articles published in languages other than English. ⋯ We identified several additional medications causing either direct or systemic effects on the air passages. In this review, we update the clinical presentation, mechanism of injury, diagnosis, and management of the airway complications related to these medications.

Case Reports
Avoiding vessel laceration in thoracentesis: a role of vascular ultrasound with color Doppler.
Thoracentesis is considered a relatively safe and well-established procedure commonly done at the bedside with minimal risk of complication. Thoracentesis-related hemothorax is uncommon; however, it may be life-threatening. ⋯ It is important for proceduralists to understand not only the tortuosity of the intercostal artery covering 25% to 50% of the intercostal space, but also the presence of traversing collateral arteries. Herein, we discuss the potential benefit of vascular ultrasonography with color Doppler during thoracentesis, with the goal of avoiding vessel injury and hemorrhage.

The outcomes of patients with idiopathic pulmonary fibrosis (IPF) who undergo hospitalization have not been well characterized. We sought to determine the frequency of all-cause and respiratory-related hospitalizations and to evaluate their impact on the subsequent course and survival of patients with IPF. ⋯ Hospitalizations are common events in patients with IPF. Most hospitalizations are respiratory-related and are associated with high in-hospital mortality and limited survival beyond discharge. Both all-cause and respiratory hospitalizations are associated with mortality, and therefore, either could be used as an end point in IPF clinical trials.

Relationships between airway inflammation and respiratory potentially pathogenic microorganisms (PPMs) quantified using quantitative polymerase chain reaction (qPCR) in subjects with COPD are unclear. Our aim was to evaluate mediators of airway inflammation and their association with PPMs in subjects with COPD at stable state and during exacerbations. ⋯ At stable state, H influenzae is associated with increased airway inflammation in COPD. The relationship between bacterial load changes of specific pathogens and airway inflammation at exacerbation and recovery warrants further investigation.

Multicenter Study Comparative Study
Risk factors for cardiovascular disease in people with idiopathic pulmonary fibrosis: a population based study.
People with idiopathic pulmonary fibrosis (IPF) have been shown to be at an increased risk for cardiovascular (CV) disease, but reasons for this are unknown. The aim of this study was to compare the prevalence of common CV risk factors in people with IPF and the general population and establish the incidence of ischemic heart disease (IHD) and stroke after the diagnosis of IPF, controlling for these risk factors. ⋯ Several CV risk factors were more prevalent in people with IPF; however, this did not account for the increased rate of IHD in this group of patients.
