Ulcerative Colitis versus Crohn's Disease

[DocSikorski]

This is a good question from USMLERx

18 y.o. woman complaints of 3 months of recurrent abdominal pain, bloody diarrhea, and weight loss.
Biopsy from a colonoscopy: mucosal involvement only, with crypt abscesses.

Which of the following is true about this disease?

a. bleeding from rectum during b.m. is common
b. smoking is associated with worsening of the disease
c. disease is often accompanied by fistulas and strictures
d. small bowel is often involved
e. perianal region is involved

[theundead]

if b.m. means bowel motion, a) is correct, although i think b) is correct too
rest of the options r for crohn's

[XpaezX]

I would say A

Smoking, small bowel, fistulas and strictures and perianal region involvement are associated with CROHN's disease.

[DocSikorski]

good job!
This is truly UC


I chose E blindly (perianal is Crohn's of course...), wordings got me here...

Smoking is a protective factor against ALzheimers and UC...

[Ayman Qasrawi]

A.

All the other options are features of Crohn's

[billy]

A is right.

[Novobiocin]

a. bleeding from rectum during b.m. is common

I think smoking protects against ulcerative colitis.
