Hope it was helpful. STEP 1 is a test of concepts. Learn it as though you are going to teach the next guy in line.

The licensure exam for physicians in my country comes in 15 days. We were given 4months of review. But with 16 hrs of binge-watching your videos, I got more stuff retained and understood than I ever did in the past three months. Thank you Dr. Neil, no matter how my exam goes, I can't thank you enough. God bless you!

My USMLE step 1 is on Monday and I’m here just binge watching all your videos. Simple and helpful. Thank you so much!!!

I think I got it for the first time! Amazing!!!!! Please do more videos..

To learn medicine with you Dr. Neil is so much fun! Thank you so much!

Excellent videos, I’m totally a fan of yours. Just for my mental sake, in the last case, I though the most reduced (deficiency) would’ve been the 17 hydro, and not the 11, because of the high BP and the ambiguous genitalia. Thank you for provide us with your knowledge !

I cannot tell you how many times I have tried to memorize that table on first aid. And dummy that i am i could never get it. But in the first 5 minutes of this video I was like ......whattttt .....no wayy.... i finally got it. Thank you so much so much.

I have skipped this table and its related questions every single time. Now, that I finally get it, I feel so stupid as to why didn't I look for your video earlier?! Best video out there, hands down. Keep up the good work.

Thanks a lot for all of your videos, I've reviewed Kaplan videos, Rx videos, boards and beyond videos. Honestly, a lot of these biostats vids you uploaded (which is what lead me to your channel) is exactly what I needed because my foreign school didn't teach biostats/epidemio well enough. The other companies' videos I mentioned honestly can't compare, 1 hour video of theirs is the equivalent to 10 minutes in your videos. Thank you so much for these, this channel is a gem and I'll recommend it to anyone who asks about step resources!

I can’t thank you enough doctor Randy! You always save my day

You are the best,Dr.Neil!!!

A reminder that you are amazing as always! Thank you :)

This is handsdown the best explanation on this topic!!! Thank you for keeping it so simple Dr Neil!!

Thanks! You're so gifted and made so easy to understand basic concepts needed for step 1, 2 and 3! I'm so grateful finding your channel while studying for Step 3. God bless you and don't stop posting videos!

Really love that the pathway connecting with the three parts of Adrenal Cortex, and that really making it easy to answer different questions. Super!

One of my friends recommended your channel, and I'm loving it. I'm a medical student. I've been struggling with this concept for...I don't know how long. Your approach is exactly right. Know the concept and then any question is doable. Thank you so much for your work!

Dr. Ryan you are simply the BEST teacher. Thank you so much for taking the time to prepare us as students for the USMLE exam. I wish you had a review program.

amazing video! Thank you so much for making it this easy to understand.

I scoured the internet to find a great and easy explanation for this beast of a theme ( congenital adrenal hyperplasia) and by far your explanation is the best . Hands down , awesome 👏!!

Thank you so much! You made it so easy to understand and memorize. You are the best 👍

lol where have you been my entire life. Love of my life queen thank you soooo much. omg

You made this 100% easier! Thank you

you are amazing ! please keep making videos like these!!!

The perfect playlist for the last Week of the long journey... Thank you very Much for everything Dr.

Thank you very much for this wonderful and concise video!

Wonderful work. Greatly appreciate it.

Thank you so much Dr. Neil

Amazing explanation!!! Thank you

such an amazign way this you've found teaching medicine with common sense. thanks dr.

Thank you for all your videos. You're a life saver Regarding the last question, can the cause be elevated ACTH (which leads to high aldosterone & sex hormones)?

the most difficult topic of step 1 for me, and u explained it so well, appreciated doc

You are a blessing to humanity

Wow I have been Trying to understand this concept for years!

dr. randy is a great teacher and a savior for all medical students preparing for usmle or any other medical entrance exams around the world. thanks a ton sir.

I've been having trouble with this for a while now ...... thanks ..... a lot

You are a truly gifted teacher. I wanna be like you.

what a great explanation !!! 😍

you are a Godsend..thankyou for making it so easy

Thank you for this video!

Thank you so much Dr.Randy my exam in 4 weeks each time I feel overwhelmed I watch your videos. Would you please make a video about visual field defects.

For the last question, since it stated "ambiguous genitalia" I would have chosen that there was a 17-hydroxylase deficiency since that would lead to underdeveloped genitalia and still can cause HTN using the aldosterone pathway. Can you explain to me why you chose 11-hydroxylase deficiency? Thank you so much!

Wooohooo dat flowchart is cooolll🤩.i used to take tym in answering question on this topic to make sure it doesn't go wrong......following ur chart reduced my answering tym to half.....thanx doc for making things easy peasy🤗...

Thanks very much sir!! This is very helpful.

You are the best, thanks

tq so much sir for making the concept easy🙏

DR Neil: COULD YOU PLEASE DO ONE WITH THE ACID BASE DISTURBANCES, AND IF ITS COMPENSATED, I FOUND SEVERAL VIDEOS BUT ALL VERY CONFUSING! GREATLY APPRECIATED.

Thanks Dr Neil.Your videos are always simple and easy to understand Can you make a video on 5-alpha reductase deficiency ,mullerian agenesis as well as androgen insensitivity.These kinda confusing in relation with the CAH’s,especially when the vignette describes the sexual characteristics

I was trying to memorize this and couldn't. Best explanation ever!!!!

Thank you Mr doctor

Holy moly 🙀 it’s so easy now .

Outstanding teacher

Thanks Doc 🤝

Love it!!

Studying for my clinical final so binge watching all your new content now 😅

Love it!

my ifom exam is tomorrow whether I will pass or no , I just want to thank you for everything , you are an amazing person.

underrated .. great

Thanks sir!

Thanks❤

Thank you don’t it’s help a lot

waiting for more endocrinology videos .especially a video on reproductive section tumors thanks

Dr. Neil,in 3:58 you say we have salt wasting due to lack of cortisol. Is it due to lack of Cortisol or Aldosterone? I think hypoglycemia may be a better choice . If I am wrong, please correct me. Thank you Sir

thanks doc, but i just gotta question.. why does 11 hydroxylase deficiency cause HTN considering that its needed for cortisol and aldosterone production

Third case very tricky

Tq sir,,lot

Plz upload video on bias questions, just thumb 👍 up for your skills.

Can anyone help me understand as to why the last question wasn't 17-hydroxlase def??

Am i missing out something? Ambiguous genitalia means incomplete external sexual features, then how can Increase 17-hydroxylase cause ambiguous genitalia instead it has to be clitoromegaly in this pt

Hello, can anyone tell me why in the 2nd question it is glomerulosa and not fasciculata? Because renin increases and BP decreases in glomerulosa aka 21 alpha deficiency

I think in last question it should be 17-hydroxylase def…isn’t ?

Oh wow! How does it feel to study step 1 with us all over again as an attending physician/psychiatrist 😂😂

Im unclear with last case as high BP and unclear genitals could have been 17 hydroxy also as explained earlier so why chose 11?

Nicely taught.. Sir

I think last question answer is 17 hydroxylase deficiency not 11 hydroxylase ?

High yield

Are these questions are from uw?

She is gonna look like a guy 😂😂😂😂
