- Otitis Media (general info)
- One of the most common childhood illnesses Refers to infection or blockage of the middle ear Generally described as Acute OM (sudden onset with short duration) or OM with effusion (presence of fluid – effusion – behind the tympanic membrane Etiology: bacterial - Streptococcus pneumoniae, H-influenzae Viruses (RSV and influenza) and allergies often predispose them to infection Peak incidence 6-12 months (onset within first year increases risk of recurrent disease
- Otitis Media (risks)
- Day care Use of pacifier after 6 months Environmental smoke exposure Bottle-feeding (putting child to bed with bottle, also causes tooth decay Allergies/URI’s
- S/S Acute OM
- Bulging, opaque, red, non-mobile TM Drainage (usually yellowish green, purulent, and foul smelling, indicates perforation of TM) Fever, irritability, fussy, rub or hold affected ear, rolls head side to side, loss of appetite OM with effusion

Presents with pain and tenderness along involved nerve and surrounding skin for 2 weeks prior to rash
- Varicella (Chicken pox) Complications
- Secondary bacterial infection of lesions – staph & group A strep from scratching can result in impetigo CNS complications –encephalitis, convulsions, coma Reye’s syndrome Corneal involvement if lesions involved in the eye
