Race and ethnicity define disparate clinical outcomes in chronic rhinosinusitis.

Background: Chronic rhinosinusitis (CRS) is a common upper airways inflammatory disease requiring multidisciplinary care.

Objective: To evaluate if African Americans (AA), Latinxs, and nonLatinx White (White) patients have different chronic rhinosinusitis outcomes and to identify associated factors impacting these outcomes.

Methods: We conducted a large prospective cohort study of CRS patients who were evaluated and followed for several clinical variables at the initial encounter and after continuous management of CRS for a mean of 40 months.

House dust microbiota and atopic dermatitis; effect of urbanization.

Background: Previous studies have shown that a child's risk of developing atopic disease is impacted by both genetic and environmental factors. Because small children spend the majority of their time in their homes, exposure to microbial factors in their home environment may be protective or risk factors for development of atopic diseases, such as atopic dermatitis.

Methods: Dust samples from the homes of 86 Black South African children 12 to 36 months old were collected for analysis of the bacterial microbiome.
