Q

CTSI

A

CT severity Index - acute pancreatitis

Grading of pancreatitis
A: normal pancreas = 0
B: enlarged pancreas = 1
C: inflammatory changes in pancreas and peripancreatic fat = 2
D: ill-defined single peripancreatic fluid collection = 3
E: two or more poorly defined peripancreatic fluid collections = 4

PLUS

Pancreatic necrosis score
None = 0
< 30% = 2
30-50% = 4

Interpretation
0-3 = mild acute pancreatitis
4-6 = moderate acute pancreatitis
7-10 = severe acute pancreatitis

NB - correlates well with other pancreatitis scores, so imaging not always necessary to assess severity of pancreatitis.

Q

HINTS

A

Head impulse

  • if PERIPHERAL, patient’s eyes keep moving with head, then saccade back (positive test)
  • if CENTRAL, patient’s eyes keep focussed on you (negative test)

Nystagmus

  • no/unidirectional suggests peripheral
  • phase changing to beat in direction of gaze suggests central

Test of Skew
patient looks at your nose, you cover one of their eyes
rapidly uncover the eye and look to see if it realigns
if the eye moves –> CENTRAL “vertical disconjugate gaze”
if the eye does not move (no skew deviation) - peripheral cause
