Immunology CD's

When trying to remember what CD's go with which MHC classes, just remember this:

Wickham's Striae

Here's a way to remember the eponymous-ly named Wickham's Striae:

Bone-oma's

I find it difficult to remember the differences between osteoblastoma, osteoid osteoma, chondrosarcoma, and osteosarcoma. So here's how I remember:

• If it begins OSTEO and ends OMA then it happens at a young age (generally <40 years)
• If it begins CHONDRO then it's over 40's (so I think of John-drosarcoma and John Lennon being shot aged 40)

 And here are the amusing ways to remember which one is which:

HIV Antiretroviral Drugs

These drugs have ridiculous names. So this memory system may only work for me.

• NRTI's - just remember the four pictures: A lamb, a dove, ABBA and Dido.
• NNRTI's - think the first 2 N's look like mountains. Everest and (Ben) Nevis.
• PI's - all end in VIR except ABBAcavir
• FI's - there's only one and it has the letters FU (FUsion) in it. Enfuvirtide.

Carpal Tunnel

It's been a while since the last Really Easy Way to Remember something - so here's a nice simple one to get back into it:

Carpal Tunnel tests:

• Tinel's sign = Tinel's Tapping sign. Tap on the dorsal aspect of wrist.
• Phalen's test = Phalen's ph-lexion test. Wrist in maximal flexion.

Remember they're only positive if the pins and needles sensation is elicited distally (e.g. not +ve if there is pain when you tap on the wrist).
