Nasal Irritation Study: Individual Factors in Nasal Irritant Sensitivity
Not Applicable
Completed
- Conditions
- Rhinitis, Allergic, Nonseasonal
- Registration Number
- NCT00041821
- Lead Sponsor
- National Institute of Environmental Health Sciences (NIEHS)
- Brief Summary
This study seeks to document differences in nasal irritant sensitivity within the population. The investigators are interested in knowing whether age, gender, and allergy status (nasal allergies) predict nasal irritant sensitivity. This is important in understanding symptom reporting patterns in air pollution situations (particularly in so-called "problem buildings"), as well as in understanding the reflex mechanism of a response of the nose to irritants (e.g., nasal congestion).
