Little is known regarding the epidemiology of chronic rhinosinusitis (CRS) in racial and ethnic minorities in the United States. This study was designed to comprehensively evaluate the current prevalence of CRS across various treatment settings to identify possible disparities in health care access and use between racial and ethnic populations. ⋯ CRS is an important health condition for all major race/ethnic groups in the United States. Significant differences may exist across racial and ethnic categories with regard to CRS health status and health care use. Given current demographic shifts in the United States, specific attention should be given to understanding CRS within the context of racial and ethnic populations. Public clinical trial registration (www.clinicaltrials.gov) I.D. No. NCT00799097.

Comparative StudyComparison of orally exhaled nitric oxide in allergic versus nonallergic rhinitis.
Fractional exhaled nitric oxide (FeNO), a well-known marker of airway inflammation, is rarely evaluated in rhinitis of different etiology. We aimed to compare the eNO levels in allergic rhinitis (AR) and nonallergic rhinitis (NAR) with/without asthma, as well as the contributing factors that interfere with elevated FeNO. ⋯ Rhinitis and comorbid asthma are responsible for increased FeNO, irrespective of atopy. However, NAR without asthma may not be considered as a strong risk factor for airway inflammation.
