+/- improved with defecation
inflammatory bowel disease
improves with defecation
emotional triggers

daytime only
irritable bowel syndrome
IBD is diagnosed clinically with
additional test necessary, 3
- colonoscopy
- radiography
- histology
[…] with biopsy should be performed in suspected Crohn’s and UC, and neoplastic pathology
ileocolonoscopy
useful for distinguising IBD from IBS

- lesions may occur anywhere from mouth to anus
- skip lesions

extraintestinal manifestations of Crohn’s
lots, but i only listed the 4 she focused on
- aphthous stomatitis
- anterior uveitis with hypopion
- erythema nodosum
- pyoderma gangrenosum
indurated, erythematous nodules in the pre-tibial region
eythema nodosum
- rapidly enlarging hemorrhagic non follicular pustule, surrounded by an erythematous halo
- very painful
- quickly ulcerates
pyoderma gangrenosum
complications of Crohn’s
4
- strictures
- fistula
- abscesses
- anal fissure
due to transmural inflammation
medication for symptom control in mild-moderate Crohn’s
5-ASA products
aim of treatment in Crohn’s
3
- get the inflammatory process into remission
- minimize negative health impacts of diagnosis and treatment
- nutrition
- medication used for symptom management/flairs of Crohn’s
- start a moderate-high dose and taper
corticosteroids
medications used as adjuct Crohn’s treatment with biologics like TNF-a
- thiopurine, azathiopurine
- methotrexate
anti TNF medications used in achieving remission in Crohn’s
adalimumab
infliximab
ant-integrin medications used in achieving Crohn’s remission
natalizumab
vedolizumab
anti-interleukin-12/23p40 mediation used in achieving Crohn’s remission
ustekinumab
second line agent after failed treatment
test for […] prior to starting the patient on anti-TNF therapy
TB
indications for surgery in Crohn’s disease
strictures or fistulas
if terminal ileum is resected, what cannot be reabsorbed?
bile acids
also issues with B12 absorption
causes steatorrhea and kiney stones
immunosuppressed Crohn’s patients should be screened for
2
cervical cancer
pneumococcal vaccines
Crohn’s patients on thiopurines should be screened for
skin/urinary tract cancer
Crohn’s patients on corticosteroids should be screened for
osteoporosis
