I can't find this!?
Isn't is just motor symptoms, thats why its Partial? Maybe Im conflating things here.
But complex partial decoded would be: Complex (lose consciousness) and partial (just 1 area of the brain, just motor).
simple seizure wont have altered cociousness....alt. concious = complex or generaliised
What's the difference between a complex partial and an absence seizure?
Absence - they just gaze off as if they're daydreaming.
but isnt stenosis gonna cause m.infarction? we have not been told any percentage of stenosis
At the end of the fourth week, the yolk sac presents the appearance of a small pear-shaped opening (traditionally called the umbilical vesicle), into the digestive tube by a long narrow tube, the vitelline duct. (Wiki)
But why does it look completely detached from the fetus? I eliminated yolk sac first because of this
If you look reeeeeeeally closely, you'll see some signal between the yolk sac and the baby. Although you can't see the entire connection, they are connected.
Pt is roughly 8 weeks pregnant so and typically by 9th week, Amniotic cavity has expended to fill entire volume of Gestational sac. So the entire black part around the fetus is GS/AC.
and also by 7 week vitelline duct obliterates between umbillicus and yolk sac
This really helped me, at least the pictures did. Here's my interpretation of the pictures in not super scientific terms: capacitance is like the "capaciy" to keep ions close to the membrane. Myelin puts a barrier between the ions in the conductive environment (ECF or ICF) and the nerve membrane. The higher the capacitance, the closer the ions are to the membrane, so it's like the charge effect is "more potent" so harder to change the membrane potentia, whereas if the ions are farther from the membrane, the charge effect is "less potent" so easier to change the membrane potential and thus easier to depolarize. Thus, with myelin, there is decreased capacity of the ions to be close to the membrane, so in demyelinating conditions, the ions can be really close to the membrane, i.e. higher capacitance.
this helped a lot!
Possibly Multiple Myeloma. That is classic for an older person with back pain and lytic lesions in the back.
osteolytic- multiple myeloma, Osteoblastic- Prostate; dont think beyond this for this exam, i have never seen a question in NBME or uworld they tried to fool us off on this concept so far.
I'd like to reiterate what's stated above... dx NOT MM in this question because MM is PRIMARY not METASTATIC @ bone (answer reads: metastatic carcinoma)
how can i trust you, you aint even a doctor
UW 1249 was perfect. #loveyourname euchromatin ha
This patient does not undergo a water deprivation test
Compulsive water drinking or psychogenic polydipsia is now increasingly seen in psychiatric populations. Effects of increased water intake can lead to hyponatremia causing symptoms of nausea, vomiting, seizures, delirium and can even be life threatening if not recognized and managed early.
Just wondering why it in not resistance to ADH action of vasopressin
because he would be hypernatremic with no ADH. can't resorb any water
low osm/urine, low os/plasma => psychogenic polydipsia
In this question the pt had a normal urine osm (80) a low urine osm would be <50mosmol/kg.
