rhinitis

 [ri-ni´tis]
inflammation of the mucous membrane of the nose; it may be either mild and chronic or acute. Viruses, bacteria, and allergens are responsible for its varied manifestations. Often a viral rhinitis is complicated by a bacterial infection caused by streptococci, staphylococci, and pneumococci or other bacteria. hay fever, an acute type of allergic rhinitis, is also subject to bacterial complications. Many factors assist the invasion of the mucous membranes by bacteria, including allergens, excessive dryness, exposure to dampness and cold, excessive inhalation of dust, and injury to the nasal cilia due to viral infection.



It usually is not serious, but some forms may be contagious. The mucous membrane of the nose becomes swollen and there is a nasal discharge. Some types are accompanied by fever, muscle aches, and general discomfort with sneezing and running eyes. Breathing through the nose may become difficult or impossible. Often rhinitis is accompanied by inflammation of the throat and sinuses. If bacterial infection develops, the nasal discharge is thick and contains pus.

Acute rhinitis is the medical term for the common cold. Chronic rhinitis may result in permanent thickening of the nasal mucosa. Treatment of rhinitis is aimed at eliminating the primary cause and administration of decongestants to relieve nasal congestion.
acute rhinitis common cold.
allergic rhinitis any allergic reaction of the nasal mucosa, occurring perennially (nonseasonal allergic rhinitis) or seasonally (hay fever).
atrophic rhinitis a chronic form of nonallergic noninfectious rhinitis marked by wasting of the mucous membrane and the glands. It is sometimes the result of trauma, vascular damage by radiation therapy, and environmental irritants, and disease has also been implicated.
rhinitis caseo´sa that with a caseous, gelatinous, and fetid discharge.
fibrinous rhinitis membranous rhinitis.
hypertrophic rhinitis that with thickening and swelling of the mucous membrane.
membranous rhinitis chronic rhinitis with the formation of a false membrane, as in nasal diphtheria; called also fibrinous rhinitis.
nonseasonal allergic rhinitis allergic rhinitis occurring continuously or intermittently all year round, due to exposure to a more or less ever-present allergen, marked by sudden attacks of sneezing, swelling of the nasal mucosa with profuse watery discharge, itching of the eyes, and lacrimation. Called also nonseasonal or perennial hay fever.
seasonal allergic rhinitis hay fever.
vasomotor rhinitis
1. nonallergic rhinitis in which transient changes in vascular tone and permeability (with the same symptoms of allergic rhinitis) are brought on by such stimuli as mild chilling, fatigue, anger, and anxiety.
2. any condition of allergic or nonallergic rhinitis, as opposed to infectious rhinitis.
