delayed onset hearing loss that is unilateral or bilateral hearing loss caused by neisseria, homophilus, pneumococcus? treatment?
meningitis
treatment = antibiotics
delayed onset hearing loss - fluctuating unilateral or bilateral hearing loss; Interstitial, keratitis, FTA positive
syphilis
delayed onset hearing loss in syphilis is caused by? What is the treatment?
treponema pallidum; treatment = corticosteriods/penicillin
delayed onset hearing loss characterized by variable damage to cochlea and vestibular apparatus with hearing loss and/or vesicular dysfunction ? What is this caused by??
Ototoxic drugs - etiology = aminoglycosides
delayed onset hearing loss characterized by enzyme interference; reversible bilateral sensorineural hearing loss and tinnitis
Ototoxic drugs - Salicylates
what is the treatment of salicylate toxicity causing delayed onset hearing loss?
stop med
delayed onset hearing loss caused by diuretics (Ethacynic acid, furosemide) is what?
transient or permanent hearing loss ; stop the drug for treatment
delayed onset hearing loss due to sensory hair cell degeneration int he cochlea due to prolonged noise
noise induced ; Initial maximum hearing loss at 4KHz - temporary after single exposure (as in rock concert) but permeant after repeated exposures
describe functional delayed onset hearing loss
consider when secondary gain, bizarre medical history, psychosomatic disorders, inconsistent audiometry
delayed onset hearing loss caused by nerve sheath tumor of vestibular division of 8 cranial nerve
Vestibular Schwannoma
Describe Vestibular Schwannoma delayed onset hearing loss features
tinnitus, unsteadiness, unilateral hearing loss with poor word recognition
what is the treatment for vestibular schwannomaa
surgery vs sterotactic radiotherapy vs observe
