Acoustic rhinometry is a method to analyse nasal airway geometry. Almost every antigen-
induced allergic reaction in the nasal cavity leads to morphologic changes known as nasal …

METHODS: 19 ragweed-allergic subjects underwent nasal allergen challenge using 10-fold
increases in Amb-a1 delivered by nasal spray. The minimal nasal cavity cross-sectional …

Local allergic rhinitis (LAR) is a recently identified phenotype of chronic rhinitis. The disease
is characterized by the negativity of skin prick test and serum specific (s) IgE for all relevant …

Nasal provocation tests have been used frequently in the study of nasal pathophysiology,
and for the pharmacologic and clinical investigations. Apart from their relevance to clinical …

Background: A reproducible standard for a graded allergen response in allergic rhinitis is
lacking. The aim was to evaluate basophil allergen threshold sensitivity, CD-sens, as a …

Due to its high sensitivity and specificity, nasal allergen challenge has a special place
among differential diagnostic tests for allergic rhinitis. Such assessment of early and late …

Background: Acoustic rhinometry (AR) uses sonar principles to map the anatomy of the
nasal cavity and has been used in other studies to assess acute airway responses to …

BACKGROUND: Many drugs for treatment of allergies, migraine headaches, inflammation,
and other indications are administered into the nasal cavity providing access to the immune …

Background Several studies have demonstrated the time course of inflammatory mediators
in nasal fluids following nasal allergen challenge (NAC), whereas the effects of NAC on cells …
