What would be the standard guidelines and subsequent recommendations to begin weaning TPN and increasing enteral feeds?
 
  What will be an ideal response?

Question 2

Mr. Page was initially diagnosed with ulcerative colitis and then diagnosed with Crohn's. How could this happen? What are the similarities and differences between Crohn's disease and ulcerative colitis?
 
  What will be an ideal response?

Answer to Question 1

The standard guidelines and subsequent recommendations for weaning TPN depend on when enteral feedings or PO intake has been advanced to >60 of estimated energy needs. Once this occurs and the patient is tolerating the alternate route of feeding well, the PN formula can be discontinued. Attention to glycemic control post-PN is important to monitor for hypoglycemia. If the patient has a history of hypoglycemia, however, it is reasonable to taper PN over 1-2 hours to avoid this problem. Overall, it is important to meet calorie needs through the transition of PN to EN for this patient in order to avoid complications with glycemic control or underfeeding.

Answer to Question 2

 UC and CD are very similar, but can be distinguished from one another by the following:

 Fever
 Wt loss
 Possibly constipation & rectal spasm
 Arthritis
 Dermatological changes
 Ocular manifestations
Complications  Malabsorption

 Toxic colitis
 Toxic megacolon
 Strictures
 Perforation
