Mnemonic for Nutrient Absorption - Iron, Folate, B12

Image found on a random site, unknown source.

So, I came up with this mnemonic last year, and this seems like as good a time as any (now that we're on the Gastrointestinal Domain) to share it with the world:

That is to say, iron is absorbed in the duodenum, folate is absorbed in the jejunum, and Vitamin B12 (Cobalamin) is absorbed in the Ileum. I imagine a stereotypical "bro" commenting on his friend, who happens to be deficient in one of these metabolites.

Yeah, that's all this post is about.

MER = DONE. MSU CHM Monster Video. Today = Amazing Day.


Officially DONE with MER, and what better way to celebrate than with the above Med Folly, featuring the M1 class (with a little of me thrown in - can you find me?). Mad props to the mastermind of it all (you know who you are, but I don't know if you want me posting your real name on my personal blog, soo...). Bravo! Anyway, the exam this morning went swimmingly - at least, as well as can be expected for an exam where most of the material has seemingly nothing in common other than that it involves stuff that can happen in the human body...

Aside from that, today I also:

- Fixed Wife's laptop by installing a new battery for HALF the price the Apple store would have charged ($60 vs. $120)
- Fixed my iPhone 4s speakers by installing a new set that I bought online for $4.40 including shipping.
- Went to the Omelette Shoppe for some celebratory feasting.
- Took Hobbes to the park and threw the ball around a bit.
- Had some great conversation with Wife about what's really important in life.

Now I'm about to get a haircut and maybe clean my desk. Oh yeah, I haven't written about my new desk! It's pretty awesome. It's this:

Mayline Futur-Matic Electric Adjustable Drafting Table

(click to embiggen)

No more sore back and unworked legs for me. I can now choose between sitting while I study or standing up. I spend about 10 hours per day at my computer/desk, and until now it was 100% sitting. Now it's about 80% standing, which is incredible. Goodbye, increased risk for DVT!

UPDATE: For those who asked, I got the above table used on Craigslist for $350. That is to say, NO, I DID NOT pay the $2,995 retail price out of my bountiful loans. That would be silly. Also, it has an electric motor (operating the switch is super fun!) that lifts it the surface up to 48" tall at the highest setting and down to 30" at the lowest. The surface tilts to be horizontal, vertical, or anywhere in between. The surface measures I think 40" x 32". Something tells me I'm going to write a full review up here at some time about this table, as I had the hardest time finding information about it when I was looking at it...

Anyway, it might be the best purchase I've been able to make this year. I can't say I did this alone - Special thanks to you who helped me fund the purchase - you know who you are. Thank you!

MSU CHM - Fun Right Now Video

I'm about to enter radio silence until tomorrow's MER (Metabolism, Endocrine, Reproduction) domain exam is over. In the interim, I leave you with Fun Right Now by the MSU CHM Class of 2017.

Well done, M1s.

M3 Clinical Rotation Schedule

A blog post wherein stuff finally seems more real.

So, originally I wanted to write a post about the female pelvic exam experience. You might think this would be awkward (it was a bit - I think that's unavoidable) and nothing more, but I learned a TON. The preceptors were incredible, the patient "volunteers" were very helpful and gave great feedback, and I felt like I learned a ton. Probably more than with any other clinical experience in the second year of med school. That was on Wednesday for me, so two days ago.

Like I said, originally I wanted to write a detailed post on that. Right now though, I'm kind of on a shortage of time. The Metabolism, Endocrine, and Reproduction Domain exam is Monday morning. Time is a commodity. 

Thus, this is a quick announcement to say:

I got my track assignment today.
It's awesome.

What's a 'track assignment,' you say? It's the order in which second year medical students (M2s aka Block II students) rotate through their third year (M3 aka Block III) clinical rotations (aka Clerkships, though I don't like this term for some reason, and thus will be referring to them as rotations).

There are only so many slots in each clinical rotation, so students are split up into groups. We rotate through the clinical placements in 8-week chunks of time, every group going in the same order through the rotations but starting at a different starting point at the beginning of the year.

I received Track D, starting on July 7th after orientation:

That's right. Starting in July, I'll be putting to good use the pelvic exam and many more skills I have yet to learn. My understanding is that I'll even have a quota of delivered babies that I'll need to fill. I ranked this track as a tie for 1st place. I mostly wanted to be able to get as much experience before the Psych/Elective rotation, where we get 4 weeks for Psych and 4 weeks for a rotation of our choice. I'm hoping to do an Emergency Medicine elective, and I want to have as much experience as possible going into that. We won't find out about our electives until later in the summer. Anyway... Yeah.

Med school is definitely getting real.

Wish me luck on Monday's domain exam.

How Many Whopper Sandwiches Does It Take to Grow a Baby?

I needed a ten-minute study break, so with the help enablement of Google, a calculator, my love of Whoppers, and the inspiration of a cartoon owl from my childhood, I pondered the question:

How Many Whopper Sandwiches Does It Take to Grow A Baby?

  • Additional metabolic needs, averaged over pregnancy = 275 extra Calories/day
  • Average pregnancy duration, conception to birth = 283.4 days
  • Total Calories To Grow A Baby = 275 Calories/day * 283.4 days = 77,935 Calories
  • Calories in a Whopper Sandwich = 630 Calories

77,935 Calories to grow a baby / 630 Calories per Whopper = 123.7 Whoppers

What does this mean?

It takes 123.7 Whopper sandwiches to grow a baby.

For the classic McDonald's lovers out there, we can see that the unit conversion between Whoppers (630 Calories) and Big Macs (550 Calories) to be 550 / 630 = 0.873 Whoppers per Big Mac. Thus:

It takes 141.7 Big Macs to grow a baby.

If you prefer to eat chicken, and you cook it as healthily as possible, there's 306 Calories per pound of chicken.

This means it would take 77,935 / 306 = 254.7 pounds of chicken meat to grow a baby. According to the interwebs, chickens are about 60% non-organ meat by weight on average, and the average chicken weighs approx. 4lbs. Thus, if a mom-to-be killed all her own chickens and supplemented her diet with only their roasted muscle meats, she'd have to slaughter and chow down (254.7 * 0.60) / 4 = 38.2 chickens to grow a baby.

Finally, my original inspiration leads me to the question:

How many Tootsie Pops does it take to grow a baby?

Tootsie Pops have 60 Calories each. 77,935 Calories / 60 Calories tells us that:

It takes 1,298.9 Tootsie Pops to Grow a Baby Q.E.D.

Disclaimer: Please do not actually try to grow a baby using any of the above dietary plans. You and your baby will probably not be in that great shape at the end of the pregnancy. You might both be dead, so please don't do it. None of this should be in any way misconstrued as pregnancy planning advice for the real world. This is just the result of a random tangent I took thanks to Google's enablement and the power that comes from having the collective knowledge of humanity at my fingertips. To reiterate, please do not attempt to grow a baby by eating a diet consisting primarily of Whoppers, Big Macs, roasted chicken meats, or Tootsie Pops. 


Learning Phlebotomy - MSU CHM M2 Spring Semester


Yesterday, I drew blood from a human for the first time. No, that's not me in the above picture, but that is my arm that you can't see, from which my friend is drawing blood. That's right - after practicing on manikin arms that have fake blood in them, we got to practice on each other.

The preceptors for the experience were great, explaining everything (which I'm sure was as easy as counting 1-2-3 for them, since this is probably the most basic thing they do in their careers) in as much detail as we could possibly want. Since I have pretty good veins (and am accustomed to getting needle sticks due to donating plasma), I ended up being a pretty good practice subject for my classmates.

What surprised me was what ended up being difficult about learning to draw blood. I always thought that getting the needle into the vein would be the hardest part, but it wasn't - at least not for me. It was much more difficult for me to find the vein in the first place, at least on people with no obvious veins. On top of that, holding the needle without moving it once it's inside the vein can also be a bit tricky. Connecting and disconnecting the vacuum tube without jiggling the needle and causing discomfort pain isn't easy, since you have to do all that with your non-dominant hand. Since I'm right-handed, I have to insert and hold the needle with my right hand, doing all the other operations with my left hand. Doable, but not the easiest thing in the world. So make sure to be nice the next time you have to get blood drawn, especially if the person doing it is new to the task.

We practiced with 22 gauge needles. The size of the needle actually decreases with increasing gauge number. The preceptor introducing us to the equipment mentioned that, as a point of reference, the needles used in donating plasma are 16 gauge, while the needles used in insulin injections are 23 gauge. To help clarify this, below left is a shot from when I donated plasma last semester after going through the Heme/Neo domain and getting curious about where "fresh frozen plasma" comes from, and on the right is the needle from yesterday's Phlebotomy session. Click to embiggen:

Above Left: The preceptor compared plasma donation needles to drinking straws. I always thought it was more similar to a bike pump, myself...

Above Right: The needles we used yesterday were pretty thin, which was resulted in very little bruising today. The blurriness of this photo makes the needle seem a little thicker than it was.

Anyway, yesterday was one more step in the direction of actually feeling like a healthcare worker. I understand that as a doctor, I will most likely not be doing many blood draws. Granted, this depends on what specialty I go into and most of all where in the world I end up practicing, but still - I understand I'm not likely to use this skill a whole ton. Phlebotomist technicians exist for a reason. STILL, it was cool to learn another skill so that I COULD do this if I needed to. Some day, I'll know enough information and will have gained enough skills to actually take care of people.

Some day, I'll be a doctor.

Nervous About Going to the Doctor - A Patient's Story

image credit: cnn.com

About a month ago, a reader contacted me after he found a post I had written about a sensitive physical exam. I will be telling his story over the course of two or three posts, with all identifying information and writing style changed, in the hopes that it might help others out there who are dealing with the same worries that he had. Here is his first email:

Hello Sir, 

Sorry, but I really don't know how to address you. I happened upon your blog while on the internet and I think I can tell you my medical problem because, well, you seem to be frank and... genuine. I guess I feel more comfortable communicating this way due to the fact that you are on your way to being a doctor... I don't know. I'm just really embarrassed.

Here's my issue: I have never had a physical exam by a medical doctor. I am 56 years old and I know this is not a good thing. My father and uncle had prostate cancer and I have been told repeatedly that I need to get a medical check-up, but it's just that I am very nervous and maybe afraid about the whole thing. I really don't know what to expect...

I am embarrassed to be unclothed in front of another person, even a doctor. I don't know what will happen, like what he will say or do - just a lot of stuff like that. I don't even really know what to ask you... I guess - have you learned anything about how to help a patient like me? I know I've got to do it, but I am really stressed out...


I wrote this in response to Thomas, but it could really go out to anyone who is dealing with similar thoughts, emotions, and feelings of fear and nervousness about going to the doctor. So, if you're reading this because you're nervous about going to the doctor, pretend it's addressed to you:

Hi Thomas,

Thank you for telling me about your situation. I think that your feelings of nervousness and even fear are quite natural, given the circumstances. I can see how someone with a family history of prostate cancer could be nervous about the idea of getting checked out, especially as you have never had a physical exam before. I think it's okay - even natural - to be nervous about this kind of thing. I also think that it might be easy to let that nervousness grow simply by imagining things to be worse than they are likely to be.

And you're right - I'm not a doctor yet. As such, I cannot give specific medical advice. However, you're also right that it will be good to get checked out in the near future. Even though I am not a doctor, I can offer my opinion on what might be the best "first step," given your feelings about going to the doctor. Before I do though, it might help to have things explained from the doctor's standpoint.

Doctors are trained to understand that getting unclothed for an examination can be very scary for patients. Most of us understand that this is not something that is easy for a patient to do. Sensitive examinations like this require a certain level of trust between the doctor and the patient. Most doctors establish this trust with their patients over years of visits, and so when sensitive examinations come up, it's not quite so scary. The patient trusts the doctor.

So, I think what might be a good idea for you would be to find a doctor and ask to meet with him or her (whichever you think you might feel most comfortable with) for a preliminary examination. You can request to not have a prostate exam done during the first visit. This way, you can have a chance to establish a relationship with the doctor, and he or she can get to know you a little better before moving on to the more sensitive examination at a later date. If you meet with the doctor and don't feel that you would be able to come to trust him or her, you could always look elsewhere for another doctor that you like better. Also, if you would prefer to speak with the physician over the phone as a first meeting, you could explain this to the nurse when you call the office for the first time. A good idea for where to get started might be to ask around among your friends for which doctor they see, and if they like their doctor. No need to tell your friends anything other than that you're looking to find a new doctor. Who knows - maybe one of your friends or relatives sees a great doctor with whom you'd get along really well!

The most important thing in all this is your health - both physically and emotionally. Any good doctor will want you to be healthy in both respects, and will not sacrifice one aspect for the other. I think it would be good for you to speak openly with whichever doctor you choose about your history and your reservations about having the rectal examination done. Any good doctor will be compassionate and understanding about what you're going through, and they should work with you about establishing trust.

Once that trust is established, I think you will find it much easier to contemplate going forward with the exam. Trusting your physician enough to form a partnership with him or her in the preservation of your health will go a long way toward helping you with your nervousness. I respect you very much for taking the time to write to me about how you're feeling, and your doctor will respect you as well. I think it's very admirable that you are considering the necessary steps for the sake of your health, even though you might be feeling scared and nervous. When you do end up choosing a doctor that you trust, I think you may eventually come to find him or her to be a source of support, rather than a source of nervousness. He or she will help you come up with a good plan so that you and your doctor - together - can deal effectively with any health issues you may have. And who knows - maybe you'll get a clean bill of health and totally set your mind at ease!

Above all, remember that all doctors start out like me - someone who wants to do everything they can to help people like you be healthy. We want to support you, and we want you to feel safe as we do so.

Please don't hesitate to write back if you have anything else you'd like to say, if you have any more questions, or if there's anything else that I can do to help. Even though we don't know each other, I will always take the time out to do what I can.



Thomas replied a few days later with a thankful and succinct response. I thought this would probably be the last I'd hear from him:

Mr. Justin,

I want to thank you sincerely for taking the time to answer my inquiry. Your explanations and insights really did help me. I am going to follow your advice and move in the direction of seeking a physician I can trust. You will be a very good doctor... Keep to your studies. You have a way of connecting with respect and understanding. Best regards - fortunate are those who will one day call you their doctor.


A month went by, during which time I thought about Thomas several times, but like I said, I never really expected to hear back from him. I just hoped everything went well. Earlier this evening, I was surprised to have the following letter pop up in my inbox:

Hello Mr. Justin,

This is Thomas here. A while back I emailed you about my concerns over having my first physical exam. You gave me a very informative and what I think was a genuine response. I am so glad I confided in you because your words gave me the confidence to find a doctor and have my first physical exam. 

I will readily admit that I was very anxious, and I am sure it was evident to my physician. However, he was exactly as you said a doctor should be when examining a nervous patient. He reassured me, and was courteous and understanding. You are wise beyond your years. You had told me that patients often imagine the physical exam to be worse than it is... That was me to a T, but now I am much more at ease now and I have been back twice to complete the physical exam. 

My doctor is going to take good care of me - certain tests for the prostate because of family history and lab work which he will analyze for various things... Well, anyway, I am sure you know all of this as you are a medical student, but I just want to say that you must keep the compassion and sensitivity that you have for people like me. 

Honestly, you really helped me tremendously, and you will be a fine doctor. I know this... You have compassion. Thank you, and do good in your studies.



I must admit, in the midst of the stress and occasional discouragement of studying for Step 1 and the next domain exam, it felt incredible to hear about Thomas' experience. It's great to have played a small part in helping someone. It feels pretty rare that we med students get to take a break from learning and actually do something. Helping people is one of the biggest reasons we started down this road in the first place, and it can be easy to lose sight of that behind the thousands and thousands of practice questions and textbook pages...

To any potential patients out there who are struggling with nervousness about going to see a doctor, I would recommend that you take heart from Thomas' experience and try to find a doctor with whom you're comfortable. After all, nearly every doctor was once a lowly med student just yearning to help people, so who knows - it might not be as bad as you think.

M3 Grand Rapids 1st Clinical Campus Meeting

MSU CHM Dean - Dr. Marsha Rappley
Med school is a very different experience from most experiences, but in its own way it's just like every other part of life. It feels like it's simultaneously flying past and d-r-a-g-g-i-n-g its slow feet across the gymnasium of time. It feels like both yesterday AND forever ago that I started M1 and had my White Coat Ceremony. I've had many PBL preceptors mention how much they'd love to be back in med school and "only have to learn." We always stare at them like they're insane, but I can understand how it will probably feel that way again. They always follow it up with some variation of, "I don't miss the tests, but I do miss the learning and lack of responsibility." I can see how, a few decades down the road, I might somehow eventually come to feel something similar. I like many aspects of med school, but I think I'm really going to enjoy being a practicing physician.

Anyway, yesterday things started "feeling real" in a new way. We had the first meeting for our clinical campus. At MSU CHM, you spend your first two years in either East Lansing or Grand Rapids. Half of the students are in each city. Then, we split up into one of six cities for 3rd and 4th years: Grand Rapids, East Lansing, Flint, Midland, Traverse City, or Marquette.

I'm staying in the Grand Rapids campus for 3rd-4th years, and like I said, yesterday we had our first meeting. We were oriented to how the next two years will work, focusing on 3rd year. Starting in July, we will be moving through different clinical rotations, called Clerkships. There are six core Clerkships, and an optional slot for an elective* (not in this order):

1. Family Medicine (8 weeks)
2. Internal Medicine (8 weeks)
3. Pediatrics (8 weeks)
4. Obstetrics/Gynecology (8 weeks)
5. Junior Surgery (8 weeks)
6. Psychiatry (4 weeks)
7. Elective Clerkship / Break (4 weeks)

*Starting last year (.: my class will be the second ever) they also allow us to take an elective clerkship. We have to take 4 elective Clerkships between 3rd and 4th years, so if you take one in 3rd year, it essentially opens up a month of free time in your fourth year. I plan on taking one during 3rd year, making 4th year that much more awesome. I have some specific interests that I plan to use this as an opportunity to pursue, so I'm pretty excited about the idea.

Everyone is split into smaller groups, and we rotate through the clerkships in a specific order, everyone in their groups. Because Michigan State College of Human Medicine is a community-focused med school, we also rotate through many different hospitals. I might be assigned to a hospital in downtown Grand Rapids for one Clerkship, then transfer to a hospital in a more rural town 45 minutes away for another clerkship. I'm looking forward to the variety of experiences that we'll get when we're exposed to different settings of practice. I'm still not sure if I want to practice in a big hospital in a city or a smaller hospital serving a more rural community, so this will be pretty eye-opening for me.

Before then though, I have to do well in all my classes as well as Step 1. Gotta keep my eyes focused on what's in front of me... Hard at times, but necessary.

As always, hope you've enjoyed reading.

Cardiology Domain = DONE

photo from wellingtonregional.com
Yesterday, we took the Cardiology Domain exam. It was a 3-hour exam (116 questions) covering 4 weeks of information spread out over 5 weeks (thank you, Spring Break Blitz!). It was a beast. I now feel pretty confident in my basic knowledge of how the heart functions, and most of the basics on what can go wrong and the (very basic) functionality of the drugs used to treat those conditions. Hopefully this knowledge will stick with me at least until June (when I take Step 1). Opinions in my class were fairly 'unified' regarding the quality of the exam itself and how good of a job it did representing the high-yield topics that we learned over the past few weeks. Since this is a public blog, I think I'll leave it at that...

Regardless, Cardio is over now, and we're on to MER - Metabolism, Endocrine, and Reproductive systems. We only have two domains left until the end of M2, and then it's on to the ISP to get ready for Step 1. I can't believe it's almost here. MER, Gastrointestinal, and then Step 1. Awesome.

To celebrate the end of one more Domain, Wife (who has apparently forsaken the blog world) and I went out to a movie last night, then came home and relaxed with some quality time together. I slept in this morning - a luxury which I haven't experienced since Cardio began - but now it's time to buckle down, muscle through, gear up, hit the books, get back in the saddle, put my ear to the grindstone, kick it, and think up more cliches.

Anyway, thanks for reading, and wish me luck!

Seeking Michigan = Awesome Video .: Nostalgia.

Video credit to Eric Hines Photography

Special thanks to my younger brother for clueing me in to this video. He shared it in nostalgia, as he lives across the country and occasionally misses Michigan (despite all the awesome mountains and snowboarding he experiences). I live here, but studying so much sometimes makes it seem like the wonders of Michigan are worlds away.

Nostalgia Abounds.
