28
Q

Risk factors for necrotizing enterocolitis

A

29
Q

Detection and treatment for Prostate Cancer

30
Q

–Codman’s triangle and Sunray appearance

33
Q

34
Q

For organ transplant what is chronic rejection

A

–Occurs after years. Due to T-lymphocytes.

–Can’t treat it. Need re-transplantation.

35
Q

When and what is happening with acute organ transplant rejection

A

–Organ dysfunction (incr GGT or Cr depending on organ) w/in 5days –3mo. Due to T-lymphocytes.

36
Q

Two organ systems you look at closely with acute organ transplant rejection

A

–Technical problems common in Liver. 1stcheck for biliary obstruction w/ U/S then check for thrombosis by Doppler.
–In heart, sxs come late, so check ventricular bx periodically.

37
Q

Treatment for acute rejection

A

–Tx w/ steroid bolus and antilymphocyteagent (OKT3)

38
Q

What’s the deal with hyperacute rejection?

A

–Vascular thrombosis w/in minutes
