define acoustic neuroma
benign tumours of Schwann cells surrounding vestibulocochlear nerve,
acoustic neuroma, aka (x2)
vestibular schwannoma
*cerebellopontine angle tumours
acoustic neuroma presentation
- bi or unilateral?
- age group
- may be associated with what palsy?
- 4main symptoms
Typically unilateral. (Bilateral =ass. w/ neurofibromatosis type II).
Aged 40-60 years
facial nerve (CNVII) palsy
BPPV
Dx manouvre
Mx manaouvre
Dx- Dix-hallpike
Mx - Epsley
BPPV
give 2
- Sx associated with the vertigo
- Sx NOT associated with the vertigo
not ass/ w/
- hearing loss
- tinnitus
comonly associated cause of epiglottitis
Haemophilus influenzae b (Hib) - reduced since vaccines
Other causes are: Infectious (Streptococcus spp, Staph aureus, Pseudomonas, Herpes simplex) or Non-infectious (Thermal, foreign bodies, radiotherapy)
key differential Sx of epiglotitis (x4)
high temperature, inspiratory stridor, difficulty breathing, drooling, and irritability.
differentials :
croup: barking cough & coryzal w/inspiratory stridor in moderate/severe cases. Sx worse at night.
Bacterial Tracheitis: Sx intermediary between croup and epiglottitis, (difficulty breathing, SOB, High temp)
2 steps in managing epiglottitis
1 Nebulised adrenaline and IV dexamethasone ) reduce mucosal oedema)
2 If medical mx unsuccessful – intubate to get definitive airway
acute unilateral vertigo lasting 15 hours. With ipsilateral dulling of hearing.
It began suddenly, no obvious trigger, while sat on the sofa.
Can hear a faint buzzing in the ear and feels nauseous.
Hx: mild viral illness one week earlier.
Exam: CN intact. Otoscopy:translucent tympanic membrane with normal ossicles and no effusion. What is the most likely diagnosis?
Acute labrynthitis
In BPPV, what type of nystagmus is seen in Dix-hallpike manouevre
rotatory nystagmus
what is the most likely location of bleeding in epistaxis>
Littles area ( comtains Kiesselbachs plexus, where belled comes form
Give 10 causes of epistaxis
4 reasions to admit patient with epstaxis
o bleeding >10 – 15 minutes,
o sesvere bleed
o bilateral bleed
o haemodynamically unstable
Mx eistaxis ( acute x 2, post-event )
acute:
nasal packing
nasal cautery
Naseptin nasal cream QDS 10/7 (reduces crusting, inflammation and infection)
Give 3 other names for glandular fever
kissing disease
infectious monocnucleosis
mono
typical infectious monocnucleosis Sx in :
- childhood
- teen/adulthood
childhood - minimal Sx
teen/adult: fever, sore throat, fatigue
other: * Lymphadenopathy (swollen lymph nodes)
* Tonsillar enlargement
* Splenomegaly & splenic rupture (rare)

what shoud patiets with EBV avoid ( x3)
Alcohol
Contact sports
Ammoxicillin/cephalosporin
x6 complications of EBV
menieres triad
typical menieres presentation
40-50 years old,
unilateral UNILATERAl vertigo (20mins-hrs, not triggered by mvtm), hearing loss (fluctuating, ass.w/ vertigo, then permanent), and tinnitus (gradually becomes permmanent
also
* A sensation of fullness in the ear
* Unexplained falls (“drop attacks”) without loss of consciousness.
* Imbalance (can persist after episodes of vertigo resolve
Dx Ix for menieres

For acute attacks
short-term:
* Prochlorperazine
* Antihistamines (e.g., cyclizine, cinnarizine and promethazine)
Prophylaxis:
* Betahistine
