Threshold for surgical repair of thoracic aortic aneurysm in patients with Marfan syndrome mnemonic

What is the threshold for surgical repair of thoracic aortic aneurysm in patients with Marfan syndrome? 

5 cm

Marfan, MarFIVE

The threshold for surgical repair in patients with Marfan syndrome is an external diameter of 5 cm. Factors that will prompt repair at a diameter <5 cm include rapid growth of >0.5 cm in 1 year, family history of aortic dissection at a diameter <5 cm, or the presence of significant aortic regurgitation.

Transposition of the Great Arteries: D-TGA & L-TGA (congenitally corrected TGA) mnemonic

Here's a mnemonic I made:

D the arteries. 

And L flipped 45 degrees counter clock wise looks like a V for ventricles so ventricles are transpositioned. Ventricles also have C that reminds me it's congenitally corrected. 

That's all!

Twin pregnancy

: increased age and parity
Family history of twins
Treatment for infertility 

2 varieties:dizygotic and monozygotic

MZ twins are of the following variety depending on the time of twinning
1-within 72hrs of fertilization =dichorionic, diamniotic
2-between 4th and 8th day= monochorionic, diamniotic
3-between 8th and 12th day=monochorionic, monoamniotic
4-after 12days=siamese or conjoint twins

Signs for chorionicity on USG:
Dichorionicity:twin peak/lambda sign
Monochorionicity: T sign/inverted T sign


Maternal complications:
Anemia
Hyperemesis
Pre-eclampsia 
Preterm labor
PPH

Twin complications:
Conjoined twinning
Twin to twin transfusion syndrome
Acardiac twin
Discordant growth

USMLE STEP1 just changed! You need to too!

 

On 26 Jan 2022, the USMLE Step 1 changed its score reporting format to Pass/Fail only. This means, that those who give their exam after this date cannot see their 3 digit score, and neither can anybody else (yes, not even PDs)
