wk 5 4 inlfammatory bowel disease clinical Flashcards
how does ulcerative and crohns differ in clinical presentation (usually)
crohns - ab pain, peri-anal disease
ulcerative - diarrhoea, bleeding
4 factors contributing to inflammatory bowel disease
pathogenic bacteria
abnormal microbial
defective containment of commensal bacteria
defective host immunoregulation
determine severe ulcerative colitis 5
> 6bloody stools/24hr
1 (or more) fever tachycardia anaemia (Hb <10.5g/dl) elevated ESR (inflam marker blood test)
ulcerative colitis would be further assessed by 4
bloods - CRP,albumin
plain axr
endoscopy
histology
t/f stool distrubtion is observed in an AXR of ulcerativ
false
absent in inflamed colon
other than no stool distributioin, what 2 things may be seen in IBD XR
thumb printing - mucosal odema
toxic megacolon - transvere> 5,5cm, caecum>9cm
3 things observed in endoscopy of IBD
loss of vessel pattern
granular mucosa
contact bleeding
extensive colitis is when the inflammation expands from rectum to
beyond splenic flexure
primary sclerosing cholangitis may arise from IBD, which disease is more likely, which is likely to be seen in an lft
UC > crohns
cholestasis (little/no bile)
define PSC
primary sclerosing cholangitis
chronic inflammation of biliary tree
peri-anal disease can develop in Crohns, define
recurrent abscess formation in peranal (ass cheeks)
pain, can lead to fistula with persistent leakage and damaged sphincters
crohns symptoms are determines by the site of disease. likely symptoms if in small intestine, colon, mouth or anus
small - ab cramps (peri-umbilical)
colon - ab cramps (lower), diarrhoea +blood, wt loss
mouth - painful ulcers, swollen lips angular chielitis (inflam at corners of mouth)
aus - peri-anal pain, abscess
what would be looked for in clinical exam to further assess a patient with crohns 3
evidence of wt loss
RIF mass
peri-anal signs
if terminal ileum affected, likely defiency to occur
vitb12
follate
t/f ulcerative colitis would cause a thickened wall surrounding affected area
false
crohns would
