Case Study

IndianJRadiolImaging_2013_23_1_81_113621_u3A 25 yo man presents at the ER with abrupt, intense pain in the right flank and ipsilateral lower abdomen. In addition to abdominal pains, he also feels  pain in the right testicle and has had to urinate frequently and always with pain. Imaging was done to aid in assessment.

Given this information, what diagnosis might you suggest? Explain the symptoms and what is revealed by the imaging. What treatment do you suggest?

Invitation to Submit Questions for Microbiology (Mini) Exam II

infectious_diseaseMy microbiology class is having a special mini-exam on the Tuesday after we come back from Spring Break. This exam will cover chapters 11 and 12 of the Cowen Microbiology text, which is basically ‘how do we kill microbes outside of the body’ and ‘how do we kill microbes inside the body?’ This exam will also have elements taken directly from Exam I presented as an opportunity to retain that material and be sure that we keep these core ideas in mind.

That said, I will be happy to entertain any questions proposed by students (or non-students) on these topics.

Pathophysiology Exam Coming up

Riddle_Me_This...My Pathophysiology class is having its first exam coming up soon (February 19th) and it’s time to solicit questions for the exam. Really, this is for my students, however, if non-students want to contribute questions, I’ll entertain those too.

Qualifications to be accepted:

1. Be a well-phrased question with a clear answer (this is helped somewhat by #2)

2. Provide four or five answers (for multiple choice) to the question and indicate which one is correct.

3. Be on topic (i.e. regarding the basic anatomy and physiology of the cardiovascular system, peripheral vascular disease, defects of the heart (congenital), valvular disease, hypertension, or myocardial infarction – other topical questions will be considered, but may appear as extra credit if they were not covered in class)

4. Post here as a reply to this blog entry so that it is visible to others.

A really challenging puzzle – even with hints

Unknown-2I’ve been watching cryptography videos again on Khan Academy. In doing so, I created this puzzle. But don’t worry about it. It’s really hard, even with the hints I provide.

Anagram Collection

Below are anagrams which all relate to one another in some way.

Image

not a hint

Unscramble the anagrams and tell me what they all have in common.

  1. Overseas John
  2. Barman Notes
  3. Druid Reefer Keg
  4. Horse Movers
  5. Simmer Key

 

Anyone can answer (send your answers to jtreml.fscc AT gmail  DOT  com) , but these anagrams are also hints for my microbiology class’ quiz on chapter 11. I don’t have any prizes I can offer, but if there is sufficient interest, I may offer future games with prizes in the future either here or at 100filmsin100days.wordpress.com, that’s my other blog on film (mostly bad ones).

First Day: In the Can

Image

I’m referring to the 2nd definition in this link

I was worried, but I think things went well for my first day of classes this semester. This Spring I am teaching my standard Microbiology course as well as a new Ecology course that I am using to teach all the things that I have never managed to squeeze into my normal General-  and Micro- biology classes.

So far I’m still trying to figure out a way that I can move my Micro class as quickly as possible into Immunology – which is my true love in biology. 

In Ecology, we jumped right into the idea of science as a tool for understanding the universe and working on some of the basic mathematics that help us feel comfortable in the conclusions at which we arrive.  

To describe this, we invented ‘VitaMax!’- a name so absurd that I thought I was inventing it, but it turns out that it’s a real thing – actually a couple of them. Who knew? Vitamax, the dietary supplement,  a multi-vitamin for Cystic Fibrosis patients, a green coffee extract for weight loss, and “A single capsule [that] guarantees firm and lasting erections 45 minutes after being taken.”

(by the way,  is it that a single capsule that gets you multiple erections?)

Well, our VitaMax! extends life … or at least that’s what we’re hoping. The data is in and we just need to evaluate whether it meets our strict requirements before getting it on the market.

Here’s the skinny:

VitaMax!® – Live life to the Max!

Without VitaMax, patients have a normal life span.

  1. Look this up and cite your source. If you are male, use the male life expectancy; if you’re female, use the female life expectancy. Assume the following data matches your ‘control’ group.
    1. Life Expectancy__________________

With VitaMax, patients lived:

     
 

life expectancy with Vita-Max:

 
 

85

 
 

92

 
 

90

 
 

74

 
 

102

 
 

90

 
 

83

 
 

77

 
 

76

 
 

83

 

 

  1. Determine the mean age patients lived to with VitaMax:_________________

 

  1. Determine the standard deviation of these patients:______________________

 

 

  1. Graph your data as either a bar graph or scatter plot.
  2. Look up a formula for computing Z-Score:

 

  1. What does Z-Score tell us?

 

 

  1. Assuming you can use the SD of your patients as representative for that in both the control and experimental group,  compute the Z-score for the average age without VitaMax __________________

 

  1. How likely is it that this average age without the drug falls within the area of the bell curve described by your experimental group’s data?

 

  1. Thinking as a scientist, how would you present this data to your company? Try to make a one-sentence statement about its efficacy.

 

10. Thinking as a marketing person, how would you pitch VitaMax to the public (without lying)? Try to make this also a one-sentence statement .

reviewing TEAS test questions

In preparing for a new semester, I’ve been downloading a few free question compilations for the TEAS test. TEAS is the ‘Test of Essential Academic Skills’ that students wishing to enter into nursing programs must take. Since many of my students in both my Biology and Microbiology classes wish to enter nursing programs and are taking required classes for that purpose, I find these questions to be very useful in directing my syllabus creation.

However, today, I found this question amongst the free samples offered at the practicequiz.com website:

Category – Science

Q – What is a term used to describe the subtle energy running through the body?
A. The Tao
B. The Force
C. Chi
D. ATP
Your answer: –
Answer: C – Chi is a term used for the subtle energy that runs through the body.
Chi is specific to Traditional Chinese Medicine. Other terms used are ki, prana and life force.

What am I to think?

I’m not sure that I am comfortable with ‘Chi’ being a legitimate concept being taught in science classes.

Am I wrong to think that the science and medicine taught to students of these disciplines should be objectively verifiable? Is ‘Chi’ a documented phenomenon? Or is this just a word / description that describes some metaphysical concept?

Wikipedia uses the following to define Chi:

Qi is the central underlying principle in traditional Chinese medicine and martial arts…Elements of the qi concept can also be found in Western popular culture, for example “The Force” in Star Wars.”

Given this loose definition for an equally loose concept, I think “The Force” is an equally reasonable answer to the question as it is posed. And no answer to this question should be acceptable or expected in a serious exam. I certainly hope that this question is an example made up by practicequiz.com, and not one that my students are ever likely to see on a real examination.

See this link for a review of chi, also known as qi or qidong, in medicine.
