Slide 1-

1 Rhinitis Dr. Mohammad Aloulah
Slide 2-

2 Definition of Rhinitis Rhinitis is inflammation of the lining of the nasal cavity. As the lining of the nasal cavity and the para nasal sinuses is continuous, inflammatory process tend to involve both areas to a greater or lesser extent.
Slide 3-

3 Classification of Rhinitis Allergy -Seasonal ,Perennial, food related ,drug induced Infectious -Acute -Chronic
Slide 4-

4 Allergic rhinitis Its an IgE mediated hypersensitivity response to allergen lead to rhinitis ,associated allergic conjunctivitis and asthma may occur. The disease is common ,prevalence depend on age ,gender, geographical distribution
Slide 5-

Allergic rhinitis classification 1. Intermittent (Seasonal) 2. Persistent (Perennial) 3. Mild 4. Moderate - severe 5
Slide 6-

Seasonal rhinitis 1. Also known as intermittent rhinitis 2. It usually lasts less than 4 days a week 3. The whole disorder lasts for about a month 4. Usually caused due to exposure to seasonal Allergens like pollen 5. Common during spring when flowers bloom 6
Slide 7-

Perennial rhinitis 1. Also known as persistent rhinitis 2. Symptoms last for more than 4 days a week 3. Whole disorder lasts for more than a month 4. This is due to continuous exposure to allergen. eg. House dust mite 7
Slide 8-

Mild allergic rhinitis Allergic rhinitis is considered to be mild if the symptoms Does'nt cause: Sleep disturbance Impairment of daily activity Impairment of work Troublesome symptoms 8
Slide 9-

Moderate allergic rhinitis This includes one or more of the following: Sleep disturbance Impairment of daily activity Impairment of work Troublesome symptoms 9
Slide 10-

Allergic rhinitis pathophysiology The reaction occurs in 4 phases 1. Sensitization 2. Subsequent reaction to allergen – early phase 3. Late phase reaction 4. Systemic activation 10
Slide 11-

11 Pathological change Local mucosal change -edema -infiltration with eosinophils and plasma cells -watery discharge -vascular dilatation -polypi -Superadded infection Involvement of sinuses -generalized thickening -polypi in the sinuses( single or multiple) -fluid effusion in the sinuses
Slide 12-

12 Etiology of Allergic Rhinitis :
Slide 13-

13 Dust mite Fel d1
Slide 14-

14 Clinical features: - Sneezing , may be in paroxysm. Rhinorrhea nasal obstruction and loss of smell Itchiness of nose ,eye,palate Tearing ,itching ,redness of eyes Burning sensation in the throat. symptom related to asthma (cough,shortness of breath, wheeze)
Slide 15-

15 Occupational allergens Rhinitis may occur as a consequence of allergins inhaled in work place frequently associated with asthma Biological agent include flour (in baker ,grain worker), laboratory animal ,wood dust,biological washing powder,latex Chemical agent -paint manufacturer and painter (spray) -platinum salt in platinum refiner -drugs in pharmaceutical worker
Slide 16-

16 Food induced rhinitis It’s a rare cause of allergic rhinitis, symptom of rhinitis often associated with urticaria, angioedema and GIT symptom Food may occasionally provoke IgE induced rhinitis In children Milk, egg, cheese, In adult nuts ,fish, shellfish, citrus fruit
Slide 17-

17 Examinaton General Local ENT examination :allergic nasal mucosa appear pale or bluish, boggy with swelling and watery discharge. there may be polyp, structural (septal deviation ,prominent turbinate). Systemic
Slide 18-

18 Investigations 1- Skin Tests: it’s a primary tool in the investigation of allergy .its positive in seasonal rhinitis ,less than 50%in others it consist of pricking skin ,with special needle few drops of allergin . Appearance of wheal and flare in 15-20 min ,the size of wheal is usually equal or greater than 3mm and interpreted by positive and negative control Antihistamine should be discontinued 3-6 days before test Intradermal test is rarely used because of extensive tissue reaction or anaphylaxis
Slide 19-

19 Skin prick test
Slide 20-

20 Laboratory tests: Laboratory tests: -nasal cytology ,eosinophil count in nasal secretion,blood -IgE level measurement (total) Specific(RAST,ELISA, cap test)
Slide 21-

21 A raised IgE level usually confirm allergic constitution but it is neither sensitive nor specific Elevated level seen in smoker and parasitic infestation
Slide 22-

22 treatment Avoidance of allergins . Drugs . Immunotherapy (desensitization) . Surgery .
Slide 23-

23
Slide 24-

24 Desensitization : it consist of injection of allergin in increasing dose S.C to be tolerated by the subject. Sublingual allergin available ,its popular but less effective .
Slide 25-

25 surgery Polypectomy Reduction surgery of inferior turbinate
Slide 26-

26 Drug Induced Rhinitis NSAID Beta blockers ACEI Oral contraceptives
Slide 27-

27 Rhinitis Medicamentosa The condition is the result of over medication with local nasal decongestants casusing rebound phenomenon occurs resulting in turbinate hypertrophy. If the decongestant treatment is repeated the condition become rapidly self-perpetuating and a chronic nasal obstruction unresponsive to decongestant results. The treatment is immediate cessation of the decongestant with replacement by nasal or systemic steroid. If this is not successful then inferior turbinectomy may be required.

28 Hormonal induced rhinitis Menstruation ,pregnancy Untreated hypothyroidism Sexual excitement (Honeymoon rhinitis)
Slide 29-

29 Infective Rhinitis Non Specific: *infections of ext.nose *Coryza ( commone cold ) *Influenza Specific Erysipelas Glanders Anthrax candidiasis Gonorrhea Diphtheria Syphilis Acute rhinitis
Slide 30-

30 Chronic rhinitis Glanders Rhinoscleroma diphtheria Sarcoidosis Lupus Vulgaris T. B Gangosa Specific Syphillis Fungi Rhinitis sicca Atrophic Simple chronic non specific

31 Infections of external nose Furunculosis Infection of hair follicles Hard tender painful red Cavernous sinus thrombosis Local heat application Systemic A.B. Paranteral A.B. (if large or cellulitis)
