7. COMMON COLD (CORYZA)
a) Airborne droplet infection
b)Caused by several viruses
A. Adenovirus
B. Picorna virus such as
i. Rhinovirus
ii. Coxsachie
c) Incubation period : 3-4 days
Illness lasts 2-3 weeks.
8. SIGN AND SYMPTOMS
COMMON COLD
1. Nasal Itching
2. Nasal Blockage
3. Rhinorrhea
4. Chills and rigors
5. Low grade fever
Initially nasal discharge watery and profuse then
goes to form thick mucopurulent due to
secondary infection due to Strepto. Haemolyticus ,
H. Influenzae, Kleb. Pneumoniae
9. BACTERIAL RHINITIS
Non Specific Infection
1. Primary : Seen in Children and Causative Org. are
Pneumococcus, Streptococcus, and
Staphylococcus. May form a tenaceous
membrane over nasal mucosa which bleeds on
removal.
2. Secondary: Due to secondary bacterial infection
over the acute viral infection. Causative Org. are
Pneumococcus, Streptococcus, Staphylococcus
and H.Influenzae.
o Diphtheritic rhinitis:
10. IRRITATIVE RHINITIS
Due to exposure to dust, smoke, irritative gases
such as ammonia, formalin, acid fumes.
Due to trauma while handling nasal mucosa eg
While removing foreign body nose.
Leads to immediate catarrhal reaction as
Sneezing
Rhinorrhea
Nasal congestion
Symptoms pass of immediately after removing
offending agent
Recovery depends on extent of damage.
11. CHRONIC SIMPLE RHINITIS
Recurrent attacks of acute rhinitis in presence of
pre disposing factors lead to chronic rhinitis
Persistence Sinusitis, DNS, Vasomotor Rhinitis
Ch. Adeno tonsillitis,
Endocrinal: Hypothyroidism/ Metabolic Factors.
Constant exposure to dust, smoke, cigarette
smoking, snuff, exposure to industrial and chemical
smoke ,alcohol indulgence are the main
predisposing factors.
12. CHRONIC SIMPLE RHINITIS
PATHOLOGY
Hyperemia
Edema mucosal membrane
Increase no. of globet cells, hypertrophy of
seromucinus gland
Blood sinusoids over the turbinate are distended if
untreated leads to hypertrophy chronic rhinitis.
13. CLINICAL FEATURES
Nasal obstruction which increases in supine
position
Nasal discharge
Hypertrophy of turbinates
Post nasal drip
Treatment
Treatment of cause
Nasal douching, Decongestant and antibiotics
14. HYPERTROPHIC RHINTIS
Mucosal thickening, hypertrophy of submucosal
seromucinous glands, periosteum of bone
Changes marked over turbinate due to
• Recurrent nasal infection
• Ch. Sinusitis
• Ch. Irritation due to smoking, industrial irritants,
prolonged nasal drops usage, recurrent vasomotor
or allergic rhinitis
15. HYPERTROPHIC RHINITIS
SIGNS AND SYMPTOMS
Symptoms
• Nasal obstruction
• Headache
• Thick tenaceous nasal discharge
o Signs
• Hypertrophic nasal turbinates with minimal or no effect
of nasal decongestion drops due to underlying fibrosis
involvement of inferior turbinate is common
• There may be compensatory hypertrophy of inferior
turbinate of opposite site if there is gross DNS.
16. TREATMENT
Treat the cause
Avoid exposure to causative agents
May require cauterization / sub mucosal diathermy
Partial / Total turbinectomy
A. Middle
B. Inferior turbinate.
17. ATROPHIC RHINITIS ( OZAENA)
Chronic rhinitis characterized by
1. Atrophy of nasal mucosa and turbinate bones.
2. Nasal cavities are roomy with foul smelling crust.
Primary Atrophic Rhinitis
1. Idiopathic
2. Hereditary
3. Endocrinal disturbances
More common in females
starts at puberty
Crusting decreases after menopause suggestive
of possibility of endocrinal pathology
18. 4. Nutritional factors : Vit A, D,E and Iron deficiency.
5. Infective pathology : Kleb. Ozaenae
Diptheroids,
Ecoli,
Staphylococcal considered
as secondary invaders causing ozaenae.
6. Auto immune disease
7. Racial Factors Common in races with broad noses
19. PATHOLOGY
Nasal mucosa : ciliated columnar epithelium is lost
and replaced by stratified squamous type
Atrophy of seromucinus glands , venous blood
sinusoides, nerves.
Arteries,of mucosa / periosteum / bone show
obliterative end arteritis.
Bone of turbinates undergo resorption and widening
of nasal cavity.
20. CLINICAL FEATURES
Females> Males
Around puberty
Foul smelling – socially unaccepted
Pt will have anosmia due to degenerative changes.
Pt will have decrease sensations and will complain
of nasal obstruction.
Nasal crusting, bleeding on removal
O/E Nasal cavity will roomy, crusting++, mucosa
pale and dry.
21. TREATMENT
Disease may persist for years
Medical line of treatment.
Nasal irrigation/ manual removal of crusts.
Nasal douche with NAHCO3 + Sodium biborate + NaCl
(1+1+2), in 280 ml of water.
25 % glucose in glycerine nasal drops (inhibits growth of
proleolytic organisms ),
local antibiotics nasal drops– Kemicetine antiozaena
Solution (Chloromycetin ,Oestradiol, Vitamin D)
Hormonal therapy(Oestradiol) to increase vascularity of
mucosa and to decrease crusting and mucosal atrophy.
Placental extract injection to reduce mucosal atrophy
22. Systemic Use Of Streptomycin :1gm/day effective against
Klebsiella
Potassium iodide by mouth Promotes and liquefies the nasal
secretion
23. ATROPHIC RHINITIS
Surgical line of treatment
Young’s operation
Modified Young’s operation
Narrowing of the nasal cavity
1. Injection of Teflon paste submucosally
2. Insertion of fat , cartilage, bone / Teflon grafts
submucosally
24. SECONDARY ATROPHIC RHINITIS
Associated with chronic granulamatous condition
such as leprosy, Syphilis, rhinoscleroma, lupus.
Unilateral Atrophic Rhinitis
May occur in patient with marked DNS.
The concave side may lead to atrophic changes
due to drying of nasal secretions in grossly deviated
nasal septum
25. RHINITIS SICCA
Occupational disease
Crust formation ++
Common in people who work in dry atmosphere
such as bakeries / cooks/ Iron and Gold smiths.
Treatment : To avoid exposure to dry conditions and
routine treatment of atrophic rhinitis
26. RHINITIS CASEOSA
Unilateral
Affects male > female
Purulent, cheesy discharge from nose
O/E : Ch. Sinusitis with inspissated pus leading to
cheesy discharge which gets secondarily infected
giving rise to Ozaenae.
Bony walls may get disrupted
It has to be differentiated from malignancy
Treatment: Surgical removal of debris.
