Clinical aspects of rhinosinusitis
Increase nasal secretionNasal obstructionBleeding or hemorrhagic secretion Fetor Altered or absent sense of smellPaine in the head or in the face.Disease of neighboring organs such as teeth, lacrimal apparatus, eyes, mouth, throat, and lungs.

Allergic rhinitis
Allergy is an exaggerated harmful response of living tissue when exposed to an allergen. Allergic rhinitis is very common disease; it affects 15% of Americans and 10% of Europeans. The prevalence of disease is increasing due to pollution; about 13% of patient has hereditary factor. Allergic rhinitis is antigen antibody reaction, IgE is the main antibody.

POTENTIAL INVOLVEMENT OF MULTIPLE ORGANS WITH ALLERGIC RHNITIS Clinical Association47.1% are having pulmonary allergy12.8% are having eczema skin allergy2.1% are having both pulmonary & eczema. Sub clinical Association:20.3% are having sub clinical pulmonary allergy.75% are having sub clinical skin allergy.

RHINITIS IN ASTHMATIC CHILDREN Approximately 80% of children presenting with asthma also have rhinitis.
Children with a history of allergic rhinitis are more likely to suffer from exercise induced asthma.
Prof .Dr. Jehad K. Albaba
-
POSSIBLE REASONS FOR CO-EXISTENCE OF RHINITIS AND ASTHMACommon ciliated epithelium.
Both are associated with allergy.
Similar allergens are associated with both conditions.
Both have a familiar link with atopy.
Possible pathophysiological mechanism-sino-bronchial reflex.

Allergic RHINITIS : SYMPTOMS
SNEEZERS AND RUNNERS: Itchy nose, sneezing ,watery rhinorrhoea, nasal congestion (variable), diurnal rhythm ( worse during day), often associated conjunctivitis. BLOCKERS:Little or no sneezing, thick catarrh (with post nasal drip), No itch, constant symptoms-possibly worse at night.
Prof .Dr. Jehad K. Albaba
-
DIAGNOSIS OF RHINITIS
Detailed medical history
E.N.T examinationEndoscopyNasal airway assessment
Other tests as appropriate: Radiology, olfaction, blood tests.
Allergy tests: nasal smear, nasal swab, RAST, total immunoglobulins.
Prof .Dr. Jehad K. Albaba
-
TREATMENT : Allergic inflammation : Allergen : IgE antibody receptors on mucosal cells ( mast, basophiles, eosinophils) . Cell activation and accumulation: Release of inflammatory mediators clinical symptoms .
So, treatment is to break the process at any stage.
Prof .Dr. Jehad K. Albaba
-
AIMS OF MANAGEMENT OF RHINITIS
Relief of symptoms
Isolation and elimination of cause of symptoms
Awareness of associated problems
E.g. sinusitis, asthma

MANAGEMENT OF RHINITIS WITH CO-EXISTENT ASTHMA
INTRANASAL CORTICOSTEROIDS: (treating upper airway inflammation) indirectly improves asthma symptoms and decreases bronchial hyper-reactivity
ANTIHISTAMINES : improve rhinitis but are not shown to improve asthma.

INDICATIONS FOR SURGERY
Anatomical abnormalities
Excessive mucosal swelling
Presence of irreversibly diseased tissue.

Symptoms and signs of sinusitis
Pain, Headache, and Tenderness. Discharge Nasal obstruction Anosmia hyposmia or cacosmiaEczema of the nostrils and conjunctivitisGeneral symptoms as cough, generalized weakness and depression.
