Hematology and coagulation study guides




Since we’re talking about blood stuff this week and next week, I thought I’d let you know that I have a few books that students have found helpful in the past:

These are all for sale but I don’t want you guys to have to buy them. If you would like a copy, drop me an email and I’ll send you a link so you can download them for free. They are NOT required – so just use them to help you study (if you feel you need help).

Exam 1 scores are up!

The scores for exam 1 are posted on Canvas. You guys did really well, as usual. Here are the stats:

Total points: 37
Mean: 33.25
SD: 3.0
High: 37
Low: 23

You’re welcome to come look at your exam any time – just drop me an email and we’ll find a time that works.

I’m still working on uploading the scores for quizzes 1 and 2…there are some weird glitches. I’ll let you know when they’re up.

Substance use disorder questions

I hope you guys got a lot out of the lecture on substance use disorder. We talk about the opioid crisis from the standpoint of the prescriber quite a bit – but we don’t have a lot of places in our curriculum where we actually talk about addiction itself.

I ask Dustin to come give this lecture every year so you can understand a bit about what the disease is like from the patient’s point of view. We’ve had a lot of great feedback on this lecture, and some students have even found it profoundly useful in their own lives. If you weren’t in lecture that day, I’d encourage you to watch the Mediasite presentation when you get a chance.

Another reason I want to talk about addiction is to dispel some of the myths around this disease. If we had more time, I’d love to talk about how recent (as in last couple years) research disproves some of these myths.

Why willpower doesn’t work

For example, a common misperception about addiction is that the addict simply lacks willpower or isn’t trying hard enough. But that isn’t true – and recent functional MRI studies are beginning to explain why.

As an addiction develops, the brain links three things together: a precipitating factor/ trigger (anxiety, for example), a behavior (such as drinking), and the result/reward  (diminished anxiety). There’s an actual anatomic pathway in the brain called the reward pathway that lights up during this trigger/behavior/reward cycle.

The more times you go through the cycle, the stronger the neural connections in the reward pathway become. There’s a saying: “neurons that fire together wire together.” It’s kind of like a cross-country skiing trail:  the more you use it, the deeper it becomes.

It turns out that as this reward pathway is growing stronger, the part of the brain that mediates logical thought (the prefrontal cortex) actually goes offline (becomes disconnected from the rest of the brain). This makes it all the more difficult to break the trigger -> behavior -> reward pathway. You may really want to quit that behavior, and you may even be alarmed by all the consequences that are piling up as a result of that behavior, but it feels like all the willpower in the world is no match for the power of the reward circuit in the brain.

You may have experienced a mild version of this if you’ve overindulged in something sugary, then felt like crap and said “never again” (and meant it!) – only to find yourself staring at an empty pint of Ben and Jerry’s while stressed out studying for an exam. What happened?!

Short answer questions

We won’t have test questions on this lecture because the material doesn’t really lend itself to multiple choice questions. Instead, I’ve posted a few short-answer questions (link below) for you to work through.  I’ll read through them and add 10 points to your total course score for thoughtfully going through this exercise (if you miss something big I’ll let you know). The questions will be open until Sunday, October 13 (I’ll nag you if you haven’t finished the questions by then).

Your answers don’t need to be long or perfect – I’m just interested to hear what you think, and I want to give you the chance to ask any questions you may not have felt comfortable bringing up in lecture. I hope you came away from the lecture with a little deeper understanding about what substance use disorder is (and isn’t). I’d love to hear your thoughts and suggestions for this area of the course.

No class November 27

Hi all – just a quick heads up: we won’t be having class on November 27th. Our lecture on Diabetes that day didn’t work out this year – so all we would have had is the quiz. Since it’s the day before Thanksgiving, and many of you will be traveling, I’m just going to make that quiz an online, take-home quiz, and we won’t have class that day. Let me know if you have questions.

Substance use disorder resources

There are a lot of excellent resources available if you would like to learn more about what substance use disorder is, and how you can help your patients. Here are a few.


Alcoholics Anonymous.
Still the program with the highest recovery rate around. Take a look around the site, check out the Big Book (the AA “Bible” – read and reread by alcoholics everywhere), and note all the literature and resources available online for health care and other professionals. You can also find a meeting, or help someone else find a meeting – here are the lists for AA meetings in Minneapolis and St. Paul.

Minnesota Recovery Connection
These guys are not affiliated with any specific recovery program (AA or otherwise). They are just a great community group that provides peer-to-peer recovery support, public education, and advocacy.

If you’re worried about someone else’s drinking (or using), Al-Anon can help you maintain your own sanity and serenity. Here are the lists of Al-Anon meetings in the Twin Cities area.


High Achiever: The Incredible True Story of One Addict’s Double Life, by Tiffany Jenkins
Also: the audiobook is read by the author, and it’s REALLY good!

Drinking: A Love Story, by Caroline Knapp.

Lit: A Memoir, by Mary Karr.

Nice Girls Don’t Drink, by Sarah Haffner.

Broken, by Bill Moyers.

Tweak, by Nic Sheff.

Quiz 2 is available

A quick reminder: there is no class tomorrow (Monday, September 30)!

We’re still having quiz 2 – we’re just doing it online (below). Feel free to use your books and/or talk about the questions together. I’ll leave it up until Tuesday (October 1).

Let me know if you have any problems! 

Welcome back!

Hi everyone! Welcome back to pathology! I’m really excited to see you guys again 🙂

This pathology course will run pretty much the same way that the General Path course ran. All course materials (lecture schedule and PowerPoints, summary videos, Kahoots, crosswords) are all on this website, and I’ll use the home page to post stuff as it comes up (student questions, schedule changes, interesting stuff that pertains to our course, etc.). As before, you might want to follow this page (right sidebar, at the bottom) so you don’t have to keep checking back all the time.

If you have questions, or just want to talk, feel free to email me or stop by my office (16-206a Moos). Or catch me before/after class. See you soon!
