hpkrazydesi Excess carotene in what way? sorry if thats a stupid question +

davidw this is directly from Goljan "Dietary β-carotenes and retinol esters are sources of retinol. β-carotenes are converted into retinol. (a) Increased β-carotenes in the diet cause the skin to turn yellow (hypercarotenemia). Sclera remains white, whereas in jaundice the sclera is yellow, which can be used to distinguish the two conditions. (c) Vitamin toxicity does not occur with an increase in serum carotene" +8

davidw β-Carotenes are present in dark-green and yellow vegetables. +

dashou19 When I was a little kid, I like to eat oranges, like I could eat 10 oranges at once, and after a few days, I could tell that I turned yellow... +8

cbreland I'm okay with missing this one +4

veryhungrycaterpillar That was fucking stupid. I've known this excess carotene fact since 8th grade due to a friend getting it, but I still wouldn't have thought of it. I went with anemia, figured it had to be folic acid since B6 would have shown up sooner than four years. UGH. +

an1 Vitamin C def would not occur in vegans and would cause scurvy symptoms. Folic Acid is HIGH in green leafy vegetables, We can assume vegans eat a lot of veggies. As this causes a megaloblastic anemia, the sclera would be expected to be pale. IFN a + ribavirin is used for hep, which is ruled out because of the normal urine and stool, and lack of scleral icterus. B1 def presents with wernickes/ Korsakoff often with excess alcohol intake and hypoglycemia uncorrected after dextrose. B6 presents with sideroblastic anemia + peripheral neuropathy (remember that INH caused B6 to be excreted resulting in neuropathy). I got this wrong. Because who has time to go through every option and think it through, and who thought carrots would make the cut for this test. +1

There's an episode in scrubs the person is orange i looked up "too much carrot" they look orange NBME language strikes again
