3-6 months
Infection rate increases
Older than 5 years old
increase in Mycoplasma pneumonia and β-strep infections
Immunity increases with?
Diameter of airways plays significant role in respiratory illnesses airways smaller, more edema in mucus membranes, increased secretion production.
Distance between structures is shorter, allowing organisms to rapidly move down.
Short eustachian tubes also straighter, allows easier success to inner ear, more horizontal.

fever control, comfort, hydration, rest
Pharmacology for Influenza in Children
Antivirals for children:
Oseltamivir (Tamiflu, greater than 2 weeks age),
Zanamivir (RELENZA).

AVOID aspirin—possible link with Reye syndrome.
Every 5-6 years
antigentic shift
Prevention of Influenza
Now recommended for children > 6mo.
New vaccine annually.
Injected and inhaled vaccines.

follows viral illness. linked with aspirin use. Cerebral edema and fatty changes in liver. Vomiting and neurological impairment.
Mitrochondrial insult. Lethargy progresses to coma.
Otitis Media (OM)
result of dysfuntioning eustachian tube: protects middle ear from np secretions, drains secretions into np, equalizes air pressure.
More common in winter. Impact of passive smoke inhalation/crowded living conditions.
Precursor to OM

Otitis Media
infection of middle ear
Acute OM
rapid onset with fever and pain
OM with Effusion
fluid in ear but no symptoms
Prolonged OM
funtional hearing loss, speech, language and congition problems
Structural Damage of OM
contacton and scarring of ear drum (tympanic membrane)
OM and Infant Feeding Methods
Breast-fed infants have less OM than bottle-fed infants due to Immunoglobulin A. Position in breast-feeding may decrease reflex in eustachian tubes.
> 6 months, OM antibiotic therapy
"watchful waiting" up to 72 hours for spontaneous resolution
<2 years old, OM antibiotic therapy
Antibiotics with persistent acute symptoms of fever and severe ear pain.
< 6 months, OM antibiotic therapy
always give antibiotics

Cephalosporins IM (If highly resistant organism or noncompliant with oral doses.
IM is painful.
Reconstitute with 1% lidocaine (without epinephrine) to decrease pain of injection).
Analgesic-antipyretic drugs for OM
Ibuprofen (only if >6 months of age).
Tx of OM
NO steroids, antihistamines, decongestants, antibiotic ear drops.
Surgical Intervention for OM -Myringotomy
