No results posted yet for this study

Summary

In a previous study the investigators found that many bakery workers were sensitized to storage mites, and many had rhinitis symptoms. The role of storage mites as an occupational allergen with clinical relevance has been questioned, and the investigators wanted to investigate whether a nasal provocation with a storage mite extract would trigger symptoms and objective signs of rhinitis in bakery workers and a control group.
