Ok fellow medfags, it's time for a HIPAA approved, totally anonymous case. Today, we have a 82 year old lady with a past medical history of ovarian cancer that is presenting with passing out once and shortness of breath. What's your differential diagnosis?

I have a question for you medfags
last night I got an awful sharp pain in my upper stomach, I drank 400 mL milk, lukewarm and an orange about 2 hrs before I got the pain, I eat healthy and exercise and other than asthma I'm a healthy fuck. Pain disappeared 2-3 hrs later when I was in bed and I was trying to sleep on my stomach
I've had ulcers and appendicitis before, this was different, now stomach is alright, just a bit sensitive
what gives?
my nonmd diagnosis is heartburn / ibs / extreme gas
>>
>>8524764
Not an MD, but I would say I have enough knowledge about medicine. It is probably heartburn but you should consult your doctor if it continues to happen also explain the pain a bit more is like stabbing, does it radiate ? etc.
>>
>>8524631
I'd need more info.
What's her past surgical? Did she have a resection, chemo, etc? Is she on any meds?
Does she have a hx of lung/cardiac issues, or are these new symptoms?
But I'd want to rule out mets big time. Check for pneumonia, do cardiac workup, CBC, get some scans. My bet would be mets somewhere though, especially the brain and lungs.

do you think, that due to the subjectivity and implicit arbitrariness of defining/(incl. self-)diagnosing mental illness, people sometimes medicalize relatively normal personal problems?
If someone has a personal anecdote of the benefit of an antidepressant, is it always reliable, given the criticisms and stringencies people put on clinical trials for having confounding factors?

>people sometimes medicalize relatively normal personal problems?
Allen Francis, lead Ed. of DSM-IV, has said that psychiatry has inappropriately medicalized 'normal life'.
>personal anecdote of the benefit of an antidepressant
The clinical trial data on antidepressants is misrepresented routinely.
https://www.amazon.com/Emperors-New-Drugs-Exploding-Antidepressant/dp/0465022006
Who cares what some dipshit in their living-room believes about some anecdote when there is widespread mis-characterization and misrepresentation among the supposedly objective, responsible professions.

>>8524445
can you give a quick summary of why it is misrepresented?

Mental illness is real you know! it's not just made up by people!

Some older people used to say that things like depression are modern inventions.
For them, people are depressed because they are lazy, and if it's not the case, they are just stupid.
So the cure for depression is to do something, work. And for the second case, just stop being stupid.
Also, there are a lot of people, including academics, students and people on this board that claims that Psychology itself is just a pseudoscience for Psychiatry like Astrology is for Astronomy.
What /sci/ thinks about it?

OP here.
I don't know if I was clear, but this is a serious board, I know that probably it can be viewed by some people like a bait because of the title but no. I could pick some better title anyway...
>>8524317
I would like if you elaborate.
I'm asking these things because I have some bad thoughts you know what I mean and I'm apathetic as fuck but don't talk about it with my family because of commentaries I heard about this issue so I'm always pretenting to be smiling and happy...

I don't see why anyone would deny it with all the evidence. In the end, even if it turns out to be false, we still get a lot of benefits from trying to solve it.
Plus, it's a good opportunity to convince the nutty hippy types to stop being afraid of nuclear energy. Just tell them the IPCC reccommends quadrupling nuclear energy and that it's safe.

What kind of grading scheme do you like better and think is more effective for STEM? Only a minimal amount of grades (like, where only midterm and final count) or lots of graded quizzes/ homework assignments/ specific tests that make major exams worth less, or something in between?
I got to a big state uni and it's basically like high school with how much homework and tests we have, and from what I've gathered it seems more prestigious uni's just have a midterm and a final with maybe a lower weight quiz halfway between each, especially in upper level courses.

I had a math professor from Ukraine. He said he thought the way American uni's did things was weird and in Ukraine his classes literally had just a final, and that was your grade for the course.

>it seems more prestigious uni's just have a midterm and a final with maybe a lower weight quiz halfway between each, especially in upper level courses.
those are europe schools. american universities focus heavily on application and grinding the material into you. its literally why our schools are the best in the world, because we cram the material down your throat and make autistic test babbies do group projects to get them used to working with real live human beings.
other countries call this hand-holding or spoon feeding. we call it making better engineers and scientists.

My book shows a proof of this but I don't understand it, also I think there's a typo at domain (f) I'm pretty sure because A is a subset of B that A U (B\A) = B not A, but the proof itself just confuses me, I'll show what I have in the next post, please help a brainlet out.

Probably one of the biggest problems of this century is and it's gonna be fact-denying people. They are very vocal, usually very well-financed, and well covered by the media.
In an ideal world, they shouldn't matter, but nowadays people like this get elected for president, or have political leadership that have full on impact on very important issues, climate change being the most important one.
Again, in an ideal world this people would just not be important in the debate of climate change and we would just look at scientist that agree or disagree with climate change, not at "believers" and "non-believers" in climate change.
How do you deal with this people? You think it's gonna be a long lasting problem?

If you gave people in 1840 the blueprints to make a WW2 aircraft, including how to make every part, how to get the materials to build each part, how to get the correct fuel, how the engine works, how long would it take for them to produce a working product?

They would never make it since that would require a very significant amount of resources and manufacturing, and they wouldn't understand many of the principles behind the technology used, so they wouldn't trust you.

Many of the materials are synthetic, even steel is. Would you give them that or would they have to learn a bunch of materials science? Would you teach them how to shape it?

How many of you blindly follow what your professors say?
By this, I mean how many of you actually prove the proofs yourself? And actually look at the axioms involved in those proofs? How many have actually questioned what they've been told?
I really hope you're not just learning more math and science because "xDDD its super kewl and makes me fucking smart. math is fucking beautiful!!"
Can you actually refute the arguments of Wildberger or pic related? Did you even question what you were told as these 2 did?
Or is hearing things from someone with the title "professor" enough for you turn your brain off? But people from the middle ages were like fucking stupid and shit because they didn't question priests, huh?
