Rhinitis is a common condition associated with significant effects on quality of life. Rhinitis may be divided into two groups, those with concurrent allergy (allergic rhinitis, AR) and those without allergy but who still suffer from nasal symptoms (nonallergic rhinitis, NAR).
Evidence indicated that adult with NAR can have de novo sensitization to aeroallergen (24%), suggesting that patients with NAR might evolve to AR. Thus the purpose of this study is to evaluate development of allergic rhinitis in children with nonallergic rhinitis.

Application of allergens to the nasal mucosa. Interpretation includes observation of nasal symptoms, rhinoscopy, and rhinomanometry. Nasal provocation tests are used in the diagnosis of nasal hypersensitivity, including RHINITIS, ALLERGIC, SEASONAL.
A form of non-allergic rhinitis that is characterized by nasal congestion and posterior pharyngeal drainage.
A group of symptoms that are two- to three-fold more common in those who work in large, energy-efficient buildings, associated with an increased frequency of headaches, lethargy, and dry skin. Clinical manifestations include hypersensitivity pneumonitis (ALVEOLITIS, EXTRINSIC ALLERGIC); allergic rhinitis (RHINITIS, ALLERGIC, PERENNIAL); ASTHMA; infections, skin eruptions, and mucous membrane irritation syndromes. Current usage tends to be less restrictive with regard to the type of building and delineation of complaints. (From Segen, Dictionary of Modern Medicine, 1992)
Allergic rhinitis that occurs at the same time every year. It is characterized by acute CONJUNCTIVITIS with lacrimation and ITCHING, and regarded as an allergic condition triggered by specific ALLERGENS.
