Presentation Of The Case:
A 61-year-old man undergoes a sigmoid colectomy for a T3N1 (two of 18 nodes) adenocarcinoma of the sigmoid colon. He recovers well and receives 6 months of adjuvant FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin) uneventfully. At his first follow-up visit, the oncologist recommended every 3 month visits for a physical, liver function tests, and carcinoembryonic antigen (CEA) measurement; every 6 month chest, abdomen, and pelvic computed tomography (CT) scans for 3 years; and aspirin, vitamin D supplementation, and exercise. Is CT scanning appropriate in the follow-up of colon cancer patients? (This case was presented at Massachusetts General Hospital Cancer Center.).

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
