CEREBELLAR DISORDER

COMMON CAUSES OF CEREBELLAR SYNDROMES

Acute (hours to days)
Cerebellar infarcts (Wallenberg / PICA syndrome)
Cerebellar hemorrhage
Encephalitis
Phenytoin toxicity

Subacute (weeks to month)
Alcohol abuse
Metastases
Paraneoplastic syndromes
Multiple sclerosis

Chronic (months to years)
Hereditary cerebellar degenaration (spinocerebellar ataxia)

=================
SHORTCASE
=================

UPPER LIMB (4)
1. arms outstretched and eyes closed --> limb of affected side DRIFT AWAY
2. arms outstretched, same level, quick push downward --> affected side REBOUND
3. finger-nose test --> INTENTIONAL TREMOR + DYSMETRIA
4. rapid alternating movement --> DYSDIADOCHOKINESIA

HEAD (3)
1. Eye --> HORIZONTAL NYSTAGMUS (> when look toward affected side)
2. Speech --> SCANNING/STACCATO
3. Head --> TITUBATION

TRUNK (1)
1. Sit patient up without support --> TRUNCAL ATAXIA

LOWER LIMBS
(2)
1. Heel-shin test --> DYSMETRIA + INTENTIONAL TREMOR
2. Knee reflex --> PENDULAR KNEE JERK

GAIT
(2)
1. Walk --> BROAD BASE + REEL TOWARD AFFECTED SIDE
2. Rombergs test --> NEGATIVE (in cerebellar disorders)

--------
Notes
--------

Unsteadiness + broadbase gait
= ?cerebellar OR ?vestibular OR ?proprioceptive

Vestibular
nystagmus; no other definite cerebellar signs; romberg negative

Proprioceptive
cerebellar sign may present; typically worse when eyes closed; romberg positive

Cerebellar
cerebellar signs; romberg negative

Cincinnati Stroke Scale

if 1 findings abnormal : probability having stroke >72%
if 3 findings abnormal : probability having stroke >85%

this scale usually use in prehospital setting.

Once the diagnosis of stroke is suspected, time in the field must be minimized.

The presence of a patient with acute stroke is a “load and go”.

A more extensive examination or initiation of supportive therapies should be accomplished en route to the hospital.

another similar name :
FAST (facial, arm, speech test)

p/s : doctor in emergency department apply this scale during patient's arrival to ED during my oncall shift in Red Box. So i think we can also use this scale to quickly assess probability of having stroke so that we can decide our further management.

Suicide Risk Assessment (SAD PERSONS) - UPDATED

Score >7 = high suicide risk

--------------------
MANNED OSCE
--------------------

1. Have you attempted suicide?
# A : No --> low risk
# B : Yes --> higher risk

2. Have you thought about dead?

3. Have you thought about suicidal (suicidal ideation)?
# No : lower risk
# Yes : higher risk

4. If yes to questions (3) :
# what kind of thought?
# method? (> serious/dangerous method, > higher risk)
# how often you thought of it?
# any specific plan?
# have you told others about the plan?
# have you actually ever attempted? (to reconfirm back with patient)
# what stop you from attempt suicide? (protective factors)
# have you make any suicidal note?
# have you make the will?
# conditions
***if patient method is to drink paraquat, have he bought the paraquat?
***if patient want to jump from high places, ask him whether he live in terrace, condo, apartment

5. ask this to patient who had attempt suicide previously (additional)
# what is the method? evaluate how dangerous is the method
# what is the chance of dying? (lock door, nobody at home, alone, etc...)
# what is the chance of rescue? (anybody at home? has tell others? etc..)
# intention of attempt? (very high? not really want to attempt?)
# what is his/her feeling after being rescued? (relief? angry to the rescuer? etc..)

6. ask to all (other factors)
# psychotic illness?
# severe depression
# alcoholism / substance abuse
# physical illness
# severe stressor
# no support
# live alone
# others.......

So evaluate this patient suicide risk subjectively based on the answers you get prof the patients.
Use logical thinking. ^_^
