Vertigo

Revision as of 23:09, 28 March 2011 by Rossdonaldson1 (talk | contribs)

WORKUP

Basic

1) Glu check

2) Full neuro (including nystagmus, cerebellar, EOM)

3) TM exam

4) CT/MRI age >55 (some studies)

Central

4) CT/MRI

5) B pulses/BP (subclavian steal)

6) Bruits

DIAGNOSIS

Peripheral

-sudden onset

-severe intensity

-seconds-hours or intermittent for days

-unidirectional/bilateral horizontal/rotary nystagmus

(fatigable, suppressed by fixation)

-positional (often one specific)

-no focal neuro

-poss auditory findings (incld tinnitus)

Central

-gradual onset

-mild intensity

-weeks-months (continuous)

-horizontal or vertical nystagmus

(nonfatigable, not suppressed by fixation)

-not positional; or associated with mult positions

-usually focal neuro

-no auditory findings

DIAGNOSTIC ALGORITHM

I. Systemic*

1) DM

2) Hypothyroidism

II. Peripheral

1) Non-auditory

A) BPV

-pos Hallpike

B) Vestibular neuronitis

-neg Hallpike

-severe x hrs, then lessons dys

-mild may persist x wk-mos

-occ assoc w/ past infect/toxin

2) Auditory (hearing loss)

A) TMs Cl

i) Meniere's dz

-clusters

-sx-free intervals

ii) Acoustic neuroma^^

-progresses to central sx

iii) Toxic (drug) labyrinthitis*

-aminoglycosides

-anticonvulsants

-alcohols

-quinine/quinidine

-minocycline

iv) Serous labyrinthitis

-h/o antecedent ENT infection

-nontoxic/minimal fever

B) TM abnl

i) Foreign body in ear canal

ii) Acute suppurative labyrinthitis*

-acute OM

-febrile/toxic

iii) Perilymphatic fistula (chronic labyrinth)^^

-?abnl TM

-chronic hx

III. Central*

1) Cerebellar hemorrhage

-toxic appearing

-severe vertigo, HA, n/v, ataxia

-cerebellar findings

-poss ipsilateral 6th

2) Vertebrobasilar artery insufficiency (VBI)

-elderly

-h/o cardiac/vasc dz

-HA; poss dysarthria/numbness

-h/o neck hyperextension

3) PICA occlusion (Wallenberg)

-ipsilateral Horners

-ipsilateral face pain/temp dec

-contralateral paralysis pharynx

4) Subclavian steal sy

-unequal UE pulse/BP

-scyncopal attacks during exercise

-arm fatigue

5) Vertebrobasilar migraine

6) MS

-bilat internuclear opthalmo^

-20-40 year olds

7) Temporal lobe epilepsy

-memory impairment/trancelike state

8) Trauma

A) Head

i) Postconcussive sy

ii) Temporal bone fx

B) Neck trauma (c-spin/lig/whiplash)

9) Infection

A) Encephalitis

B) Meningitis

C) Brain abcess

*Must R/O

^Bilat internuclear opthalmo (MLF) = abduction of bilat eyes okay w/ acomidation but not medial gaze

^^ENT follow-up

Admit if unable to walk (all)

SYMPTOMATIC TREATMENT

1) Diazepam (PO/IV)

2) Meclizine

3) Benadryl

4) Promethazine

BPV TESTING*

Hallpike (test): quickly from sitting to supine, head to one side, brought 30deg off stretcher; + = nystag/reproduced symptoms

Eply (treatment): Head at 45deg rotation, 30deg hyperextension; 30 sec motions-->RUQ,LUQ,LLQ,sitting w/slight flexion (for pos Hallpike on right)

Brandt-Daroff (home treatment)

*caution if concern for VBI
