When is observation without antibiotics appropriate for a child with acute otitis media?

According to 2013 A A P/A A FP guidelines, you may refrain from antibiotics and simply observe if:

° Age 6 months to 2 years + unilateral AOM without otorrhea + mild illness + appropriate follow-up available + antibiotics can be started promptly if symptoms worsen

° Age > 2 years + unilateral or bilateral AOM without otorrhea + mild illness + appropriate follow-up available + antibiotics can be started promptly if symptoms worsen

° In either case, the decision to observe without antibiotics should be made jointly between provider and parent/caregiver(s)

° Antibiotics should be started if improvement is not noted in 48-72 hours

W hat are the classic signs and symptoms of bullous myringitis?

Bullous myringitis is a bullous/vesicular inflammation of the tympanic membrane that may occur in association with acute otitis media. It typically manifests as follows:

» More painful than; usual acute otitis media

° Otoscopy: large, reddish vesicles on the TM

W hat is the treatment for bullous myringitis?

° ____________________ is a common organism —> treat with oral___________________

° Topical analgesics

7. W hat are the diagnostic features of mastoiditis?

° Symptoms occur days-weeks after developing acute otitis media

° Erythema, edema, tenderness behind the ear

° External ear displaced

° Diagnosis made from C T scan of the mastoid process

8. W h at are the distinguishing characteristics of acute labyrinthitis?

° Acute onset of vertigo, nausea, vomiting and nystagmus - Auditory function preserved = vestibular neuritis

Hearing loss + above symptoms = labyrinthitis

° Single episode that lasts days to weeks (usually not longer than 2 weeks)

° Preceded by a viral URI

° Nystagmus: horizontal, suppressed with visual fixation and has a fast phase away from the affected side

0 Abnormal head thrust test: W hen examiner rapidly turns the patient’s head to the affected side, the patient is unable to maintain visual fixation

° Gait instability, but preserved ambulation

° Absence of focal neurologic defects

9. W h at is the treatm ent for acute labyrinthitis (vestibular neuritis)?

° Typically subsides spontaneously within weeks

° Corticosteroid taper shown to improve recovery

° Symptomatic treatment only indicated for the first 48 hours of illness E.g., scopolamine patch, meclizine, metodopramide or promethazine Long-term recovery is theoretically delayed if used long-term

° Vestibular rehabilitation exercises

° M R I if > 60 years of age, headache, focal neuro signs, vascular risk factors or sustained vertigo inconsistent with acute labyrinthitis (vestibular neuritis)

10. W h at is the m ost com m on cause of conductive hearing loss in adults? W hat is the m ost com m on cause of sensorineural hearing loss in adults?

° Conductive — otosclerosis

° Sensorineural — presbycusis

11. Cholesteatom a:

° Overgrowth of desquamated keratin debris within the middle ear space that may eventually erode the ossicular chain and external auditory canal

° Causes: negative middle ear pressure (chronic retraction pocket) from eustachian tube dysfunction or direct growth of epithelium through a T M perforation

° Commonly associated with chronic middle ear infection

° PE: grayish-white “pearly” lesion behind or involving the T M , conductive hearing loss, vertigo

° Treatment: surgical removal usually involving tympanomastoidectomy and reconstruction of the ossicular chain

AUDIOVESTIBULARDISORDERS 12. W hat is the treatment for Ramsay Hunt syndrome?

Ramsay H unt syndrome is herpes zoster oticus and is treated as follows:

° Narcotic analgesia for pain relief

° Oral steroids to decrease inflammation

° Antiviral therapy with valacyclovir (highest efficacy), famciclovir or acyclovir
