Humidifier Disinfectant-Associated Children's Interstitial Lung Disease.
Beginning in 2006, epidemics of a fatal lung injury of unknown cause in children were observed in Korea every spring. A recent study demonstrated that this type of children's interstitial lung disease (chILD) is associated with humidifier disinfectant use. ⋯ This study suggests that humidifier disinfectant inhalation causes an idiopathic type of chILD that is characterized by spontaneous air leak, rapid progression, lack of response to treatment, and high mortality. Further safety studies must be performed on common environmental compounds, particularly those that enter the human body by an unusual route.

Risk Factors and Comorbidities in the Pre-Clinical Stages of Chronic Obstructive Pulmonary Disease.
There is little information about comorbidities and their risk factors in the preclinical stages of chronic obstructive pulmonary disease (COPD). ⋯ Premorbid risk factors and comorbid diseases were more prevalent in the preclinical stages of COPD and smokers without COPD. Physical inactivity and smoking were more strongly associated with the presence of comorbidities compared with airflow obstruction. Clinical trial registered with www.clinicaltrials.gov (NCT 01314807).
