So, this says sympathetic also spared and hypothalamus also spared. Then what was wrong with this clinical case??
i think the sympathetic system is actually impaired b/c it's cut before it can "outflow"...at least it's the only way this makes sense
I agree. I think the question stem is saying the sympathetics were lesioned. Not that they were spared.
yeah, i’ve never heard of antiphospholipids increasing PT time ...
Not sure if that little detail was to throw us off. I think the point of the question was to ID antiphospholipid syndrome based on the clinical criteria (spontaneous abortion + thrombosis)
I actually went down a rabbit hole with this one recently - essentially in vitro findings =/= in vivo findings, clot-wise with anti-phospholipid antibodies.
No mention of lupus anticoagulant, anticardiolipin, or anti Beta 2 antibodies. FA mentios prolonged PTT but nothing on PT. What a piece of shit question. But thanks to the dudes above who explained it
UWorld mentioned "prolong aPTT (and sometimes PT)" in APS
@yb_26 Can u please tell the QID because the one I have seen it says, "Although patients often have prolonged ptt (because the antiphospholipid interferes with ptt test), pt is normal."
