 | | For example, in nonasthmatic individuals with seasonal AR, nasal allergen challenge caused an influx of eosinophils in both nasal and bronchial epithelium and lamina propria, demonstrating that nasal allergens produced a generalized airway inflammation that extended well beyond the nose.8 The reverse was also true. |
 | | Nasal endoscopy can be used when needed to find nasal and sinus pathology, which might be missed by routine speculum and nasopharyngeal examination.1 Other components of examination in AR are eyes, oropharynx, ears, skin, and chest. |
 | | Histamine is released within minutes of allergen exposure, mostly by mast cells, and mediates the early symptoms of AR: sneezing, itching, rhinorrhea, and to a lesser extent, congestion (see Table: "Mediators of the Early- and LatePhase Reactions in Allergic Rhinitis"). |
