Antibiotic Classification

Please use the buttons above to vote for whether this one works. Have been working on this for a while and it may only work in my head!
Each picture above is just a way of linking a random antibiotic name with an actual class. Such as Quinolones -> "Quick Sip" -> Ciprofloxacin.

For adverse reactions add:
  • The pepsi van is driven by a red man (vancomycin causes "red man" syndrome)
  • The gentleman has to shout "ALLO GUVNOR" since he is deaf (ototoxicity in gentamycin)

Also, on the penicillin side of things here's how I remember the Beta-Lactams:

ECG interpretation with one glance

Often I find someone hands you an ecg print out, points to one lead and says "...obviously the defect is antero-lateral to the septal portion of the apex" (or something similar). So here's a neat picture based way to remember which lead covers which area.

All ECG's are presented in this format:
and I like to superimpose the following picutres:
So Lead I, aVL, V5 and V6 are lateral (picture of Caffe Latte), Lead II, III and aVF are inferior (Info sign), chest leads V1 and V2 are septal (7 in french, sept), chest lead V3 + V4 are anterior (Ant). Don't worry about aVR - I don't think anyone ever does. So just like in the kids game, all you have to do is remember where each of the pictures are.

What is an EEG?

Ok, so people often get confused over what exactly an EEG is. Time to look at some EEG fish....
In our fish tank we have loads of fish swimming around randomly. There are also 3 cameras looking at different parts. The first sees only one fish (how sad), the next sees 3 fish swimming to the left and the next sees loads of fish swimming to the right. If we add in a bonus camera then we could probably figure out which way the fish were swimming at a certain depth.

Replace cameras with electrodes and fish with action potentials and you've got an EEG. Remember the crazy squigly line trace you get from an electrode is the result of groups of neurons (fish) firing (swimming).
