News, A Look Back: Happy New Year and Picks for Best Posts

First:  Best wishes for a Happy and Healthy New Year 2011 to everyone! 

Since I have been writing this blog (which began in July 2007), I have yet to assemble a list of  “favorite posts” from the backlist.  The first week of a brand New Year seems like a good time to offer up this collection.

Here’s a list of top picks from the EBM & Clinical Support Librarians@UCHC blog (in no particular order):

  • Digital Natives (Jun 12 2008) compares the learning environment of today’s graduate students with those from my generation (i.e., circa 1970’s).
  • A continuing series called Show Me The EvidencePart 1 is linked here. Part 2 – go here.  And Part 3 (which has received the most hits over time) link is here.

That’s a compilation to start out the New Year, folks – and thanks for reading this blog.

The Friday Post #28: Economics, Wordle, Cephalopods and an Emergency Room Rap

Here’s the Friday Post #28 for Feb 28 2009.  There’s enough doom-and-gloom, and down economic news from all around the world this week to make you want to cry.  Bah! So turn the TV off.

Wired reporter Felix Salmon published an article on Feb 23 2009 entitled “Recipe for Disaster: The Formula that Killed Wall Street“.

Here’s a Wordle tag cloud based on words taken from a recent news article from BBC:

Instruction, Evidence Based Medicine, Web 2.0: More Radiology Sites for A Long Weekend!

Anything about radiology seems to be a popular category for this blog, so I’m pleased this week to write about several outstanding teaching-and-learning sites for medical students everywhere, found recently through Delicious.

Physician Gillian Lieberman, faculty at Harvard Medical School and Beth Israel Deaconess Medical Center in Boston, has created several in-depth radiological collections based on her own work in that specialty (with many contributions by medical students or residents with whom she has worked) at Lieberman’s ERadiology.  These sites offer core-learning content for first and second-year medical and dental students, in various formats.

For your consideration, I have highlighted several examples from these free, online tutorials: .

  • Lieberman’s Learning Lab which is described on the main page as: “… 450 mini seminar presentations on Cardiac, Respiratory, GI, GU, Musculoskeletal, and CNS topics. These are prepared by Harvard medical students in collaboration with Dr. Gillian Lieberman. They are detailed and cover both radiologic and clinical aspects. The intended use is for medical students, residents and staff.

A 2nd year medical student who was in my PBL group last fall suggested that I write about LearningRadiology, a teaching/learning source she uses frequently. This is a comprehensive site with many areas of multimedia, interactive quizzes, links to podcasts (in iTunes).

You could spend all day on zooming around in this educational site! I liked the 22 Must See Diagnoses for Medical Students” (media player required).

There are radiology learning modules grouped for medical students, such as this one shown below (screenshot):

Finally… more of a post-medical education portal, The Doctors Channel could also be called “By Doctors, For Doctors”.  Created by physician David Best, the free site offers a variety of free educational content for physicians including educational or commentary videos, a section on “dueling doctors”, podcasts, CME opportunities and more.  To gain access to the full contents of the Doctors Channel, you’ll need to sign up and first log in (at no cost).  Two examples of content:


Education, Instruction, PBL: Thinking about Trauma, Brains and Textbooks

This post is about participating in problem-based learning. As a non-clinician, sometimes I’m at a loss informationally in PBL. There are eight medical students and one experienced physician in the room with me and – frankly speaking – a certain amount of the clinical material is over my head.

Much of what is covered in problem-based learning focuses on recognizing classic or emergency symptoms in a hypothetical patient, parsing etiology, past medical or family history, looking at evidence presented through physical exam, lab data, radiological images, occasional photographs. Each case unfolds over a two-week period; students are given several pages of the case and time to discuss the “patient’s chief complaint“, list data, formulate questions. During the following days, they do research using clinical sources, then create a narrative, concept map or bulleted problem-list to bring to the class the next week.

One standard schematic used to manage patient data is to organize it in the following way: What is the Nature of… , What is the Meaning of… , What is the Significance of… , What is the Relationship of… (or WIN-WIM-WIS-WIR)? A different script, created by a student several years ago is: Etiology, Findings, Pathogenesis, Treatments, Psychosocial considerations.

The utility of this information sorting/schema matters to graduate students in their first two years of medicine, when they are learning basic medical science, organ systems, human health over the lifespan in addition to spending one day per week assisting at the office of a community physician. Time spent in PBL is for learning to think like a clinician in a low-risk setting, and to create a foundation for recognizing illness patterns. (Thanks to Diedre B who created this page found on Medical Education Wiki).

This week I picked up a new textbook from the New Book Shelf, titled Trauma Anesthesia, edited by Charles E. Smith (Cambridge University Press, 2008 ) and began reading through the chapters. This 606-page text is a gold-mine of technical information, evidence-based flowcharts, tables, dozens of photos and patient radiographs, and the strong point of the book is discussing typical presentations in trauma. I wasn’t aware that unintentional injury is the leading cause of death in U.S. for those under the age 45, that in 2002, 162,000 deaths were recorded due to traumatic injuries and the cost of medical treatments for treating these injuries total $200,000,000,000 each year (Source: MMWR, 2004:53:1-4). Trauma can be sustained in many ways… mechanical, chemical, thermal, radioactive or biological insults to the human body.

But a comatose patient can’t answer the question: “What brought you in today? Maybe that is one of the attractions about choosing emergency medicine: the adrenaline of in-coming, when the physician has to make the call in limited time and with information that is only partially forthcoming. This textbook, and books like it, provide the technical framework for making that call.

For example, the chapter on Head Trauma refers to the Brain Trauma Foundation where the following statistics about traumatic brain injuries were found:

Education, Instruction, News: An Online Radiology Community… Aunt Minnie.com

Since I seem to be on a Radiology kick these days (two previous postings about radiology in the last 10 days on this blog), I might was well continue it with a site that Radiology faculty and residents have told me about: AuntMinnie.com.

Following is an excerpt from their “About AuntMinnie” page:

  • “AuntMinnie.com provides the first comprehensive community Internet site for radiologists and related professionals in the medical imaging industry.
  • AuntMinnie.com provides a forum for radiologists, business managers, technologists, members of organized medicine, and industry to meet, transact, research, and collaborate on topics within the field of radiology with the ease and speed that only the Internet can provide.
  • AuntMinnie.com features the latest news and information about medical imaging.
  • The staff responsible for content on AuntMinnie includes executives, editors, and software engineers with years of experience in the radiology industry.”

While access to the site is free, registration is required before any in-depth content from the site will be shown… and content is what this site is, to be sure, excellent at delivering.

Following are a few selected screenshots from the site:

Educational Sites: Radiology, Open Access Journals and GoldMiner

Here is something new!

The American Association for the Advancement of Science (AAAS) provides an invaluable (and free) news/alert service called EurekAlert which I’ve mentioned before on this blog.

A press release from EurekAlert is how I learned of a specialized search engine named Goldminer, produced by the American Roentgen Ray Society (ARRS), which on Jan 29 2008, announced a joint collaboration with BioMedCentral (BMC) to make BMC peer-reviewed, open access journals linked within a search on Goldminer™.

Below are a few excerpts from the Jan 29 2008 press release explaining the nature and the purpose of these unique biomedical resources:

GoldMiner, the ARRS radiology search engine, is designed by and for radiologists. It understands medical vocabulary, and uses sophisticated tools from the National Library of Medicine to recognize synonyms and abbreviations of radiological terms

BioMedCentral, the open access publisher of peer-reviewed biomedical research, has partnered with the American Roentgen Ray Society to add journals and images to GoldMiner™. BMC has contributed over 170,000 images and 225 journals to GoldMiner.

You can use this specialized search engine in several ways. For example, I did a search on “pancreatic neoplasms” (shown below):

The pull-down menus allow you to narrow your retrievals by Modality (i.e., CT, MRI, PET, Photo, Ultra Sound, X-ray, Nucl Med, Photo, Graphic) and also by Age or Gender. Click the link for Medical Subject Headings (MeSH) from National Library of Medicine to learn which clinical terms are the best to use for pertinent retrievals from GoldMiner™.

Now – how cool is that! 🙂

EBM, Educational Sites, Videos: Bullets, Velocity, Radiology and the Coen Brothers

As Joel and Ethan Coen illustrate so aptly for us in their 2007 film, No Country for Old Men, high-velocity projectiles do a great deal of damage to the human body.

So this post is about… damage.

1. Educational, Illustrative Damage: Here is a video which graphically illustrates the lethal power of projectiles fired at high speed… pity the poor vegetables:

2. Fictional Damage:

Javier Bardem (who played a wonderful romantic lead in the film The Dancer Upstairs) plays the role of a soft-spoken, murdering monster who seeks the return of his suitcase full of money. He kills practically everyone he lays eyes on in this movie.

3. Actual, Evidence Based Damage:

I was introduced to the radiological work of Surfactant via a recent post on one of my favorite blogs, Scienceroll, having to do with trauma, radiology and the weird things that humans do to themselves and (unfortunately) to others (thanks for the link, Berci!).

Surfactant has posted a variety of photo work on Flickr which is very compelling… See what trauma surgeons and emergency physicians see by clicking on his Radiology Photoset here including the images entitled “The Evil that Men Do” and “Homicide”:

No Hollywood glamour there, just real-life human suffering.

Flickr provides other links to clinical radiology/CT/PET image sets… as an example, here is the link to RadsWiki.

See also Real Radiology Group, The XRay Pics Pool and The Medical Imaging Gallery links on Flickr.

These collective works are definitely evidence-based medicine in the most literal sense.
