Mnemonic Monday: Cyanotic Congenital Heart Defects

By Haley Masterson

This mnemonic has been passed around pediatric residency programs for decades but is rarely mentioned in the medical school setting (which is unfortunate, because it works so well).  You can, however, check it out in First Aid for the USMLE Step 1.

Negative Sense Mnemonic

By Tim Durso

Negative Sense MnemonicIn general, First Aid does a fantastic job of including great mnemonics to help cram a vast amount of medical knowledge into your brain. One concept that I always struggled with was remembering the characteristics of negative sense RNA viruses. Unfortunately, First Aid didn’t include a mnemonic for this, so I took it upon myself to make one for my own benefit.

Drum roll, please…

You give NEGATIVE reviews to a BAD PROF. (more…)

Your Medical School Study Habits Become Your Doctor Work Habits

By Luke Murray

Your Medical School Study Habits Become Your Doctor Work HabitsIt was Friday afternoon and the morning lectures had just finished. I surveyed the challenge ahead of me: 20 lectures that I had only been through once, another 6 that I haven’t been through at all, and the test was Monday morning…

Time to do the obvious: panic.

In the words of every 13-year-old that’s ever sent a text message: “JK…kinda.”

While I did not physiologically manifest a full blown panic attack, the ‘plans’ I put together were almost totally void of the two things that would make them useful: (more…)

The “O”bnoxious Problem with the TORCHS Mnemonic

By Joe Savarese

The Obnoxious Problem with the TORCHS MnemonicPerhaps my clever title gave away the topic of this post, but my augmented interest in the TORCHS infections (since I started my OB/GYN rotation earlier this week) has encouraged me to create a better mnemonic. First, let me review the classic one. There are multiple versions, but here is one of the most common.

TToxoplasma gondii
OOthers
RRubella
CCMV
HHerpes simplex virus-2 and HIV
SSyphilis

If you are a second year student, I understand this mnemonic has been drilled into your head by now. Professors probably refer to it simply as the “TORCHS infections.” My intent is not to alter the traditional mnemonic but to improve the unhelpful “Other” stem part. (more…)
