Clinical InformationClinical

  • Rhinitis

    inflammation of the nasal mucosa, the mucous membrane lining the nasal cavities.

  • Rhinitis, Allergic

    an inflammation of the nasal mucosa triggered by allergens.

  • Rhinitis, Allergic, Perennial

    inflammation of the mucous membrane of the nose similar to that found in hay fever except that symptoms persist throughout the year. the causes are usually air-borne allergens, particularly dusts, feathers, molds, animal fur, etc.

  • Rhinitis, Allergic, Seasonal

    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.

  • Rhinitis, Atrophic

    a chronic inflammation in which the nasal mucosa gradually changes from a functional to a non-functional lining without mucociliary clearance. it is often accompanied by degradation of the bony turbinates, and the foul-smelling mucus which forms a greenish crust (ozena).

  • Rhinitis, Vasomotor

    a form of non-allergic rhinitis that is characterized by nasal congestion and posterior pharyngeal drainage.

  • Allergic Fungal Sinusitis

    fungal infection in the paranasal sinuses characterized by common allergy respiratory symptoms, recurrent nasal polyps and/or asthma with buildup of allergic mucin.

  • Rhinosinusitis

    obstruction of sinus drainage into the nasal cavity and inflammation of the nasal mucosa in the paranasal sinuses.

  • Chronic Rhinitis

    chronic inflammation of the nasal cavity mucosa. it may lead to post-nasal drip resulting in chronic sore throat and chronic cough.

  • Chronic Laryngitis

    persistent laryngitis usually caused by smoking, heavy alcohol consumption, voice abuse, or gastroesophageal reflux disease. it results in hoarseness and other voice changes.

  • Allergic Rhinitis, CTCAE|Allergic Rhinitis|Allergic rhinitis

    a disorder characterized by an inflammation of the nasal mucous membranes caused by an ige-mediated response to external allergens. the inflammation may also involve the mucous membranes of the sinuses, eyes, middle ear, and pharynx. symptoms include sneezing, nasal congestion, rhinorrhea and itching.

  • Allergic Rhinitis|Allergic rhinitis

    inflammation of the nasal mucous membranes caused by an ige-mediated response to external allergens. the inflammation may also involve the mucous membranes of the sinuses, eyes, middle ear, and pharynx. symptoms include sneezing, nasal congestion, rhinorrhea, and itching. it may lead to fatigue, drowsiness, and malaise thus causing impairment of the quality of life.

  • Atopic Rhinitis

    allergic rhinitis with a positive skin prick test (spt equal or greater than 3 mm) to any allergen.

  • Grade 1 Allergic Rhinitis, CTCAE|Grade 1 Allergic rhinitis

    mild symptoms; intervention not indicated

  • Grade 2 Allergic Rhinitis, CTCAE|Grade 2 Allergic rhinitis

    moderate symptoms; medical intervention indicated

  • Grade 2 Rhinitis Infective, CTCAE|Grade 2 Rhinitis infective

    localized; local intervention indicated

  • IL13 wt Allele|ALRH|Allergic Rhinitis Gene|BHR1|Bronchial Hyperresponsiveness-1 (Bronchial Asthma) Gene|IL-13 Gene|Interleukin 13 Precursor Gene|Interleukin 13 wt Allele|MGC116786|MGC116788|MGC116789|NC30 Gene|P600

    human il13 wild-type allele is located in the vicinity of 5q31 and is approximately 3 kb in length. this allele, which encodes interleukin-13 protein, is involved in both the regulation of immune responses and the modulation of b-cell maturation and differentiation. the gene plays a role in the regulation of immunoglobulin e class switching.

  • Infectious Rhinitis|Non-Allergic Rhinitis|Rhinitis infective

    an inflammatory process affecting the nasal mucosa, usually caused by viruses (e.g., rhinovirus, adenovirus, parainfluenza virus, and coronavirus). it is characterized by chills, headaches, mucopurulent nasal discharge, coughing, and facial pain.

  • Perennial Allergic Rhinitis|Non-seasonal Allergic Rhinitis

    allergic rhinitis caused by indoor allergens and lasting year round.

  • Rhinitis

    an inflammation of the mucous membrane lining the nose, usually associated with nasal discharge.

  • Rhinitis Infective, CTCAE|Rhinitis Infective|Rhinitis infective

    a disorder characterized by an infectious process involving the nasal mucosal.

  • Seasonal Allergic Rhinitis|Hay Fever|Hay Fever

    allergic rhinitis caused by outdoor allergens.

  • Vasomotor Rhinitis

    inflammation in the nasal cavity mucosa that results from the abnormal regulation of the blood flow in the nose. it may be caused by temperature fluctuations, air pollution, strong odors, and tobacco smoke. it results in chronic nasal congestion, sneezing, and running nose.

  • Rhinosinusitis

    inflammation of the mucous membranes lining the nose and paranasal sinuses.

Patient EducationClinical

Nose Injuries and Disorders

Your nose is important to your health. It filters the air you breathe, removing dust, germs, and irritants. It warms and moistens the air to keep your lungs and tubes that lead to them from drying out. Your nose also contains the nerve cells that help your sense of smell.
