Syncope spectrum

-Normal
-Prodrome→ early autonomic sx
-Presyncope→ near-syncope
-Intermediary→ gray-out/ syncope threshold
-Syncope
-Recovery

Clinical history

What EXACTLY happened before, during, and after the event?

-open-ended quest at begining, than close
-LOC, incotinence
-Witness and recurrence
*avoid term fainting
-Triggers (sleep dep, drugs, stand) vs premonitory symptoms

Primary or Secondary?

1st question - onset

Hyperacute→ think vascular
Acute/subacute→ broader ddx
Chronic→ reassure if unchanged

Use SNOOP4 for screen secondary causes

Characterize

-Pain features - "SOCRATES"
> quality (throbbing, pressure, stabbing)
> duration & frequency
> associated sx (photo/phonophobia, N/V, auto sx)

Diagnosing Neuropathy
Clinical Pearls

"There are numbness, tingling, and burning pains in the feet, with weakness of the legs, so that the patient walks with difficulty and unsteadiness"

Sir William Osler (1849 – 1919), Canadian physician

1/ Image
Presentation
Referral "neuropathy," self-dx googling numbness/tingling
-hard≠numbness≠tingling≠weak

-true negative sx (loss) are more specific
>unable feel floor T°
>unable sense sand/cold surfaces

-positive sx (gain) are non-SP
>dd: CVI, MSK, compression, positional

Localizing

P.neuropathy patterns
-stocking-glove distribution
>1st stocking (knee) level → 2nd hands: likely DM
-dist → prox progression in limbs
-symmetric sensory loss
