First 12 seconds. I thought neonatal period stops at 28 days??? Even 3 months. Those are infants. Otherwise good lecture.

Done

Took the peds practice shelf which overlaps a bit here on Asthma and they were using the updated guidelines of beginning with corticosteroids first and then adding Albuterol as prn. Wondering if anyone studying for the IM shelf can confirm if that's the Asthma guidelines for the IM shelf?

Great job 🏆

Thank you!!

this is sooo good always rely for my shelfs. :)

extremely helpful

16.16 uw says first line for T.pedis is topical ,not oral

Great for PA students too!

Dude, great content, but the monotone for an hour is killer 😅

subluxation of the radial head is treated with hyperpronation OR supination-flexion, I believe. BTW..I'm a fan. Thanks for all your videos ❤

Do you have PDF notes?

Watched your videos two days before my Step 2 CK last december and ended up with a 269! Super high yield content and thoroughly enjoyed going through all your videos for rapid review. I have my step 3 in two days and I had to come back here knowing how much it would help me :) Thank you, you are amazing!

Great content, but pls note (timestamp 36 mins) Cystic Fibrosis is Obstructive, not restrictive type lung disease. Thanks

Might as well just burn it! lol 😂

Do ace inhibitor still have a mortality benefit or is it just made up blockers and aspirin? The last time that I studied this I only saw beta blockers and aspirin listed.

the cancerous HPV are 16 AND 18 not 16-18 and also 31 and 33 among others. not exclusive

Nitrates is contraindicated in Right sided MI not inferior MI, inferior MI effects the RCA which can lead to right sided MI if the proximal RCA is occluded but that does not always happen. The RV is supplied by the proximal RCA and its right marginal branch. ST elevation in V4R-V6R is a contraindication to nitrates because it implies an RV infarction

At 16 he mentioned AS,HTN in longrun becoming DCM, in Uw it says concentric hypertrophy; where as DCM causes eccentric

At 15.16 he is saying that kusumauls sign is seen in CT , but in Uw they mentioned it only for constrictive pericarditis

Excellent review

thank you father

Loved the review, thank you!

I have been using your videos for every shelf. Surgery is my last one, and this is the only time I've actually known everything in the video before watching it. You helped me not only to review, but your framework has helped me target high yield concepts and study with more efficiency and less stress over time. These are old videos and idk if you even read comments anymore, but thanks a ton!!

Crazy how students and attendings talk so bad about IMGs yet US MD and DO students preach about Dr. HY and he's an IMG. Just my 2% but thank you Dr. HY

0:40 Truelearn for Level 2 said the treatment for bacterial meningitis in a newborn was ampicillin + cefotaxime (or ceftazidime or cefepime). The video's answer is also correct but moreso for neonatal PNA/Sepsis. I hate how specific these questions try to be when there are multiple answers. thank you to Dr. HY nonetheless

Doc, I have a question, does the book of CK include family medicine and obstetrics and psychiatry? I am gonna to buy the book ?

Yo does anybody have a transcription of this video? I saw somebody transcribe the notes into bullet point format for his Neuro Shelf video and it was insanely helpful. Thanks!

New criteria for AAA repair is if its >/= 5.5 cm or growing at a rate faster than 0.5 cm every 6 months

Man the explanation of RTA’s! Just woww! Kudos to you man !

thank you very much!

Hi Dr, can you do a video on very easy approach on CT scan and MRI brains always have hard time learning them and even antibiotics please

Thank you !

Note so I dont get confused: Erb’s palsy is C5 +C6 :)

You are awesome...thank you brother

12:54 i think this is incorrect. Next best thing would be thrombectomy, not aspirin
