Rhinitis &Rhino-sinusitis

Rhinitis

Rhinosinusitis

Definition

As the lining of the nose and paranasalsinuses is continuous, inflammatoryprocesses tend to involve both areas.

Sinusitis

Defence- Mechanisms

1. Mucociliary system, √2. Epithelial integrity,3. Reflexes (cough, sneeze),4. Lysoszymes, opsonins &complement,5. Immnoglobulins (secetory IgA,

IgE)6. Macrophages & lymphocytes.

Mucociliary clearance:This depends upon

1.Amount of mucus.

2.Mucosal resorption

3.Patency of air current

4.Ciliary action.

Allergic Rhinitis

• Allergic rhinitis is an Ig.E mediatedhypersensitivity of nasal mucous membranecharacterized by:

• Sneezing, itching, watery rhinorrhea and asensation of nasal obstruction.

• It may also involve the lining of paranasalsinuses.

• It occurs in atopic individuals who are exposed tocommon aero-allergens

• It is genetically inherited either:Autosomal recessive.Autosomal dominant.

Complications

Otitis mediaSinusitis

Allergic rhinitis and bronchial asthmafrequently coexist.

• Aspiration of secretions.• Dryness of LRT.• Increase vagal stimulation.• Bacterial toxins.• Inflammatory cytokines.

Therefore, treatment of rhinitis with improvement in nasal airwaymay also improve symptoms of bronchial asthma.

Investigations

Skin allergy test

An allergen extract is placedinto skin by either scratching

or pricking with a sharpdevice or by intradermal

injection using a syringe &needle.

Investigations

Blood test:

• Total IgE.

• Specific IgE (RAST test)

About 50% of patients with allergic rhinitis have normal levels oftotal IgE and 20% of non-affected individuals can have elevated

total IgE levels.

Investigations

Eosinophils:

Blood sample

Nasal smear

Only supports the diagnosis of allergicneither sensitive orrhinitis but it is

specific.

Non-allergic eosinophilic rhinitis.

Parasitic infection.

Influenza

One of the most common infectious diseases in human.

It is caused by influenza virusthat is classified as type A, B & C.

InfluenzaIt may occur in epidemics.

Spanish flu epidemic 1918 killed 20 millions all over the world.

InfluenzaTwo types of influenza virus.

Human influenzaAvian influenza

InfluenzaTwo types of influenza virus.

Human influenzaA person infected with a particular flu virusstrain develops antibody against that virus.

As newer virus strains appear throughantigenic shift and drift , the antibodiesagainst the older strains no longer recognizethe "newer" virus, and infection with a newstrain can occur.

Chronic nasal disease characterized by progressive atrophy ofnasal mucosa and the underlying bone of the turbinates withformation of scanty viscid secretions that rapidly dries toform crusts that emit a characteristic foul odor (ozaena).There is associated abnormal patency of nasal passages.

3. Atrophic rhinitis

The exact cause is unknown1) Chronic bacterial infection; Klebsiela, Pertussis,

Diphtheria.

2) Nutritional Deficiency; Vit-A deficiency, Fedeficiency.

3) Endocrinal Factor; estrogenic deficiency.

4) Autoimmune.

Etiology (primary)

Incidence

• Endemic in subtropical & temperate climates.

• In Egypt, it affects 1% of the population.

• More in those living in unhygienic conditions.

• It occurs more commonly in females at the time of

puberty and this supports the hormonal theory of

the role of estrogen in the etiology of atrophic

rhinitis.

Etiology

Chronic bacterial infection: Coccobacillus. Bacillus pertussis or

mucosus. Klebsiella ozaenae. Diphtheroid bacilli.

Etiology

Nutritional Deficiency:

▫ Vitamin A deficiency.▫ Iron deficiency.

Etiology

Autoimmune Disease:Due to loss of tolerance

• Viral infection.• Malnutrition.• Immunodeficiency.

Etiology

Endocrinal factorMainly estrogen deficiency; the proof is:

Occurrence in girls around puberty. Aggravation of symptoms during menstruation. Improvement of some cases by estrogen therapy.

Etiology (secondary)

1. Excessive surgicaldestruction of nasal mucosa.

2. Chronic exposure to irritant,cocaine or toxic agents

3. Healed stage ofgranulomatous disease.T.B., Scleroma.

4. Radiotherapy.

• Biopsy is diagnostic and treatmentsimilar to lung condition

3. Scleroma• Chronic specific infection of the respiratory tract

esp. the nose (rhinoscleroma)• Klebsiella rhinoscleromatis• Mode of infection (unknown)• Not uncommon in Egypt• Teenagers especially in females (poor classes)• Granulomatous tissue infiltrates the submucosa

oropharynx) with soft palate fibrosis,subglottic stenosis and rarely trachealand bronchial, maxillary sinus andmiddle ear or ET or lacrimal sacinvolvement

Scleroma- pathological features

• Hypertrophic: overgrowth ofdense fibrous tissue

• Atrophic : process ofreabsorption and breakdownof tissues

• Cicatricial: scar left by theformation of new connectivetissue over a healing sore orwound.

Scleroma- management• The organism can nevertheless be extremely difficult to

be eradicated by antimicrobials.• Once the diagnosis has been confirmed by biopsy,

treatment must be intense and prolonged.• Bactericidal antibiotics in large doses are given in large

doses for a minimum of four to six weeks and arecontinued until two consecutive cultures from biopsymaterial are proven negative.

• Initial surgical debridement prior to chemotherapy is reportedto be useful in granulomatous stage.

• The traditional antibiotics used are streptomycin andtetracycline, but the lenghthly nature o the treatment can leadto problems with adverse effects and compliance.

• Recent reports have emphasized the good results achieved withoral therapy with rifampicin, sulphamethoxazole- trimethoprimcombination, and ciprofloxacin.

• Local application of 2 percent acriflavin for a period of eightweeks has been noted to be both efficacious and non-toxic.

• Locally applied rifampicin has been used with success.

Scleroma- management

• Radiation to total dose of 3000 - 3500 Gy over three weeksdestroys scleroma but, the currently available antimicrobials, isunlikely to be required.

• In late cases where disease has been eradicated, further plasticreconstructive surgery may be required.

• This may be carried out by nasal endoscopy and laser, ifappropriate.

Fungal Sinusitis• Invasive

▫ Presence of fungal hyphae within the mucosa,submucosa, bone, or blood vessels of theparanasal sinuses

• Non-invasive▫ Absence of fungal hyphae within the mucosa and

other structures of the paranasal sinuses

Fungal Sinusitis - Classification• Invasive

1. Acute Invasive Fungal Sinusitis2. Chronic Invasive Fungal Sinusitis3. Chronic Granulomatous Invasive Fungal Sinusitis

• Non-invasive1. Allergic Fungal Sinusitis2. Fungus Ball (fungus mycetoma)

1. Acute Invasive Fungal Sinusitis• Most lethal form of fungal sinusitis – mortality

50-80%• Rare in immunocompetent patients• Two clinical populations

▫ Poorly controlled Diabetics – ususally caused byfungi of order Zymocycetes (Rhizopus, Rhizomucor,Absidia, and Mucor)

▫ Immunocompromised with severeneutropenia (chemotheraphy patients, BMT, organtransplants, AIDS) – Aspergillus accounts for 80% ofinfection in this group

2. Chronic Invasive FungalSinusitis

• Usually immunocompetent• History of chronic rhinosinusitis• Usually persistent and recurrent disease• Maxillofacial soft tissue swelling, orbital

invasion with proptosis, cranial neuropathies,decreased vision, can invade cribiform platecausing headaches, seizures, decreased mentalstatus

3. Chronic GranulomatousInvasive Fungal Sinusitis

• Primary paranasal granuloma and indolentfungal sinusitis

• Primarily found in Africa (Sudan) and SoutheastAsia, only few case reports in US

• Immunocompetent• Caused by Aspergillus flavus• Characterized by non-caseating

granulomas in the tissues

4. Allergic Fungal Sinusitis

• Most common form of fungal sinusitis• Common in warm, humid climates of

Southern US• Hypersensitivity reaction to inhaled

fungal organisms resulting in chronicnoninfectious inflammatory reaction - IgEtype I immediate hypersensitivity and type IIIhypersensitivity are involved

• Common organisms implicated – Bipolaris,Curvularia, Alternaria, Aspergillus, andFusarium

Allergic Fungal Sinusitis – Clinical-cont.• “Allergic mucin” within affected sinus

which is inspissated mucous theconsistency of peanut butter witheosinophils on histology

• Younger individuals, third decade,immunocompetent

• Often associated history of atopy withallergic rhinitis or asthma

• Chronic headaches, nasal congestion, andchronic sinusitis for years

5. Fungus Ball

• Older individuals, female>male• Immunocompetent• Asymptomatic or minimal symptoms with

chronic pressure or nasal discharge• Cacosmia (perception of foul odor when no

such odor exists)
