Laparoscopic Surgery Performed at 4X HD
Saturday, November 14, 2009
Joshua Schwimmer, MD, FACP, FASN
The holy grail of resolution is not high definition video, but
telepresence — resolution so good it feels like you're looking through a window, not a TV set or a monitor. Resolution so detailed you feel like you are
there.
Dr. Steven Palter, an obstetrician/gynecologist and fertility specialist, recently performed the world's first laparoscopic surgery with the RED camera at a resolution equivalent to 4X HD. The procedure was presented on October 20 at the 65th Annual Meeting of the American Society for Reproductive Medicine (ASRM) in Atlanta. According to Dr. Palter,
"The images are the sharpest, most detail-rich and color-correct endoscopic images ever created anywhere. There is not a more accurate view inside the human body... By increasing resolution to this level we allow the surgeon to be actually immersed in images that surpass the live surgical experience. The resolution approaches that of the human eye but it is combined with 10 fold magnification through the telescope which operates just inches away from the disease. The progress from regular surgical film technology is like comparing sitting in an HD home theater to watching a video on a cell phone..."

Finding Doctors and Health Care Professionals on Twitter
Friday, November 13, 2009

A little over a year ago, before
Twitter was the tech/pop culture phenomenon it is today, doctors like myself had a problem: how do you identify other health professionals on Twitter? (At the time, there must have been at least dozens.
Dozens.)
This was
the first solution. In retrospect, it was hilariously cobbled-together:
This is a feed containing the conversations of all known doctors and medical students who use Twitter: http://feeds.feedburner.com/doctorsontwitter. (If that doesn't work, you can try the original feed from Yahoo Pipes instead.) Technical details, for those interested: I used this list of doctors/medical students on Kidney Notes, ran each person's Twitter feed through Yahoo Pipes, then burned a FeedBurner feed.
When
FriendFeed debuted, I created "
The Doctor's Room," which was populated by both Twitter feeds and RSS feeds of physicians. Unfortunately, the "room" feature was poorly designed by FriendFeed (which has since been acquired by Facebook). Like the Yahoo Pipes experiment, the FriendFeed room was an educational failure.
A month ago, Twitter finally debuted the "lists" feature, allowing each user to create subscribable lists of other users. Below is a sample. (For clarity, the second column is the number of users in the list, the third column is the number of users subscribed to the list. Got it?)

While not a perfect solution, lists are a simple way to discover health care practitioners on Twitter. (
Finally.) Services like
Listorious have also appeared which use the Twitter API to create searchable lists of lists.
For easy reference, here's a list of some of the more popular lists of doctors on Twitter:

Hilarious Journal Articles and NCBI ROFL
Saturday, September 12, 2009

Two years ago, I began collecting "hilarious journal articles" and posting them on
kidneynotes.com. Here's a sample:
At last count, I had collected 98 articles.
If you're interested, you can peruse the entire collection at delicious.com.
(Please note that sometimes these articles are about conditions that are deadly serious, and my intention is not to make fun of anyone, but to show appreciation for humor in scientific writing, which is often dry.)
Hilarious journal articles even have their own awards: the
Ig Nobel Prizes, which has been presented at Harvard since 1991. You'll find the complete collection of prize winners
here.
And since January of 2009, two Molecular and Cell Biology graduate students at UC Berkeley have written a blog devoted entirely to squirt-milk-out-your-nose grade scientific research. Their website is
NCBI ROFL, which stands for
National Center for Biotechnology Information — creators of
PubMed, where most of the abstracts are published — Rolling On The Floor Laughing.
It's outstanding.
Go have a look.

Information Overload, the Index Medicus, and PubMed
Friday, July 31, 2009
Joshua Schwimmer, MD, FACP, FASN

The growth of medical knowledge is difficult to visualize. One classic representation is the
Index Medicus — a comprehensive index of medical journal articles — whose bound copies filled the shelves of medical libraries for 125 years. In 2004, however, the National Library of Medicine decided to stop publishing the
Index. The first reason was practical: the
Index Medicus had grown from 82 pounds in 1985 to an estimated 152 pounds in 2004. The second and more important reason was the widespread availability of the search engine
PubMed — an electronic database of medical literature available for free via the Internet — which made the printed index obsolete. Compared to the
Index Medicus, PubMed was more convenient, could be searched more easily, could be updated more quickly, and certainly weighed less. Copies of the
Index Medicus are now a historical curiosity; many physicians now search the medical literature exclusively through PubMed.
The story of the
Index Medicus and its successor, PubMed, illustrates three ideas.
First, the quantity of new medical information is more than any single physician can absorb, and keeping up to date with this expanding body of knowledge is challenging. As of April 2009, for example, PubMed contained information on 18,782,970 citations in the medical literature and was adding over 670,000 new entries per year. Doctors must not only absorb this flood of new ideas about treating, diagnosing, preventing, and understanding disease — deciding which information is relevant and which is not — but also learn how to apply and explain this knowledge to the patient sitting with them in the exam room or laying ill in a hospital bed.
Second, in parallel with this unprecedented expansion in medical knowledge, new media and technologies have emerged — of which PubMed is one example — which has made the task of searching, organizing, and retrieving relevant information easier. Potential sources of information for physicians include not only printed journal articles like those indexed in PubMed, but lectures, case conferences, and newer Internet resources such as reference tools (e.g.,
UpToDate), discussion groups, online
expert systems, clinical resource tools, and podcasts.
Third, the expansion of medical information and proliferation of new technologies has required physicians to develop new skills and strategies to keep their knowledge current. Often, the availability of new knowledge overwhelms physicians’ ability to process it, a condition known as information overload. In physician’s offices, one symptom of information overload is the common spectacle of unread piles of medical journals stacked up on every available horizontal space.
While many medical schools now require classes on searching the medical literature and evidence-based medicine, few resources have been available designed to teach physicians how to learn and practice medicine more efficiently. (That's why, over two years ago, I started writing
The Efficient MD blog.)
Since then, I'm glad to report that online resources for physicians have proliferated. Ways of improving efficiency and reducing information overload are now common topics on medical blogs. For example, see recents posts in
Life in the Fast Lane,
Clinical Cases and Images, and
Musings of a Distractible Mind.
Thanks for reading!

Jacque-Lynne Schulman, Stephen Greenberg, Margaret Vugrin, and Dean Giustini for helping me with an updated estimate of the weight of the
Index Medicus. Any inaccuracies in this post are, of course, my own.)

Case Study of a Physician's Use of the iPhone 3GS (Part 1)
Sunday, July 05, 2009
Joshua Schwimmer, MD, FACP, FASN
I recently upgraded my original iPhone, which I purchased
two years ago, to the iPhone 3GS. Truthfully, I wasn't expecting much of a change. Sure, I read the marketing hype — faster processor! 3G speed! GPS! voice control! better camera! — but I didn't expect the new model to make much of a difference in my daily clinical practice as a
nephrologist.
Boy, was I wrong. I've been using the 3GS so much that by the end of the day, I've not only burned through the iPhone's battery, but I often burn through the external battery in my
Mophie Juice Pack Air case as well. (I highly recommend the Mophie, by the way, which removes a subtle disincentive to using the device because you're worried you may run out of battery life.)

The following is a multi-part description of my own use of the iPhone 3GS. In my experience, the best way to learn to use a new gadget is to look over the shoulders of others, watch how they use it, ask lots of questions, and experiment constantly. (Most iPhone owners are familiar with the phenomenon of having someone grab their phone, scroll through the applications they have installed
and ask, "What's that one do?")
So if you have an iPhone, and are a health care professional or patient, this will hopefully be helpful. Even if you don't have an iPhone, some of the applications I describe are available for other PDAs — or they soon will be, since the iPhone has significantly raised the bar for what a mobile device can accomplish.
(Original drafts of these posts were written on the iPhone app
BlogPress.)
