Agreed-Confused b/c Meckel Diverticulum is legit the classic example of a choristoma (p. 221 FA 2019)
Maybe they're thinking gastric mucosa is a more specific answer?
Apparently. "Baroreceptor activity is reset during sustained increases in blood pressure so that in patients with essential hypertension, baroreceptor responsiveness is maintained."
"It is a universally accepted phenomenon that vascular baroreceptors reset to operate at higher pressure levels in hypertension."
Okay, so they can reset to normal levels, but wouldn't this patient already have undergone their reset? Why would the receptors further decrease?
I thought that eventually their LV would hypertrophy and fail, leading to decreased stroke work.
From Costanzo Physiology:
"The sensitivity of the baroreceptors can be altered by disease. For example, in chronic hypertension (elevated blood pressure), the baroreceptors do not “see” the elevated blood pressure as abnormal. In such cases, the hypertension will be maintained, rather than corrected, by the baroreceptor reflex. The mechanism of this defect is either decreased sensitivity of the baroreceptors to increases in arterial pressure or an increase in the blood pressure set point of the brain stem centers."
Hypertensive heart disease causes concentric LVH - impaired diastolic function, preserved ejection fraction
Could someone explain the significance of the skateboarding injuries? Is this some part of ADHD that I'm missing?
So mad I second-guessed myself on this. Its always PCP or huffing glue smh
Think I had UWorld question on this. Apparently in this age group (teens), inhalants like glue are the first drugs they try. Only ever seen this on It's Always Sunny but w/e
Dr. Ryan said, "rIght sided murmurs increase with Inspiration" and "lEft sided murmurs increase with Exhalation" --> always helps me!
Other bacteria that splenectomy patients are at risk for are Hemophilus influenza and Neisseria meningitidis
If you see HYPOtension in a CAH question, it's gotta be 21-hydroxylase!
My special friend just gave me a mnemonic for this that I did not know. If the 1 is the 1st digit (11, 17) = hypertension. If there is a 1 in the 2nd digit (11, 21) = virilization.
and FA2019 pg 662:
Vit.D usually activated in Kidney. but They can be also activated by Macrphage like this case.
How do you know the gracile fasciculus is damage?!?!
which parte of the image its damage?, the pink? or black?
the pink park yes
i still don't see where the damage is lol! FML
i finally figured it out lol that was a slow moment i hope im not this slow on step yikes!
@hyperfukus I had the same problem at first, marked it and then came back. If you remember, in the spinal cord the white matter and gray matter are "reversed" compared to the brain. That said, if the butterfly shaped region (ie, the gray matter) is colored (in this case) lilac and the rest (ie, white matter) is blackish, the only thing that is actually abnormal, is the region where the dorsal columns are, because it stains just like the normal gray matter. After that, you have to think about which fasciculus is damaged, the gracilis or the cuneatus. The gracilis is medial while the cuneatus is lateral (picture someone with glued legs and open arms). Hope this helped
Gracilus Fasciculus = Graceful legs
Check out FA2020 pg 508
myelin= black --> color of the normal white matter
no myelin= pink --> color of the normal gray matter and the damaged area
Dorsal columns= vibration, proprioception, pressure fine touch
F. graciLis= Lower body
F. cUtaneous= Upper body
the dorsal optic radiation is also known as "baum's loop"
APD--> swinging flashlight test, light in the AFFECTED eye will result in dilation of both pupils inappropriately
