The document summarizes acute otitis media (middle ear infection). It notes that it is caused by pyogenic (pus-forming) organisms and is more common in children, especially of lower socioeconomic status. It can spread to the middle ear through the eustachian tube, external ear, or bloodstream. Risk factors include recurrent colds and other respiratory infections. Common bacteria include Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. The infection progresses through stages of occlusion, presuppuration, suppuration, resolution, and potential complications if not treated. Symptoms include earache, fever, and deafness. Signs include a red, bulging e

6.  More common in infants and children f lower
socioeconomic group.
 Follows viral infection of upper respiratory
tract.

7.  Via eustachian tube
 Via external ear
 Blood borne

8.  Recurrent attacks of common cold.
 Upper respiratory tract infections.
 Extanthematous fever like measels ,
diaphtheria or wooping cough.
 Infections of tonsils and adenoids.
 Nasal allergy.
 Chronic rhinitis and sinusitis.
 Cleft palate
 Tumors of nasopharynx

9.  Streptococcus pneumoniae 30%
 Haemophilus influenza 20%
 Moraxella catarrhalis 12%
 Streptococcus pyrogenes
 Staphylococcus aureus
 Pseudomonas aeruginosa

10.  Stage of tubal occlusion
 Stage of presuppuration
 Stage of suppuration
 Stage of resolution
 Stage of complication

11.  Oedema and hyperaemia of nasopharyngeal
end of eustacian tube blocks the tube leading
to absorption of air and negative
intratumpanicpressure.
