HY lecture notes:
A bit of a briefer segment here focusing on a few very high-yield points for the FM shelf + 2CK.
Colorectal cancer (CRC) screening
- Start colonoscopy at age 50, then do every 10 years.
- Sigmoidoscopy + barium enema combo can be done every 5 years as an alternative.
- Fecal occult blood (FOB) can be done annually as a second alternative.
If Hx of colon cancer in the family (first degree relative only – i.e., must be parent or sibling):
- Start colonscopy at age 40, or ten years before the age of Dx in the 1st-degree family member, then every 5 years.
- For instance:
- Dad was Dx with CRC at age 57; when to start colonoscopy? –> answer = age 40, then every 5 years.
- Dad was Dx with CRC at age 43; when to start colonoscopy? –> answer = age 38, then every 5 years.
When to start lipid screening for FM shelf
- Age 20 years, then every 3-5 years.
- There’s a Q on one of the FM forms where they give healthy 23M and ask for the appropriate screening; answer = check lipids.
How to make Dx of diabetes mellitus
- Two fasting glucoses 126 mg/dL or greater.
- Any one random glucose measurement of 200 mg/dL or greater.
- Any HbA1c measurement of 6.5 or greater.
- Normal fasting glucose is 72-99 mg/dL.
- Impaired fasting glucose is considered to be 100-125 mg/dL.
