Health 2.0 News: Doctors using Google, Hospital Blogs being Blocked

It’s not just patients who turn to Google or other search engines to research medical information. According to Google, 86 percent of doctors say they now use  Internet on the job. Of that group, the majority start at Google, which they use as a source to look for general information about diseases and drugs, writes pediatrician Dr. Rahul K. Parikh in a special piece for the Los Angeles Times.

  • MAD MMX – Opening Title Sequence

You may want to think twice before your next visit to the doctor’s office. According to Dr. Barbara Starfield’s now-famous study, iatrogenic deaths (those resulting from treatment by physicians or surgeons) are the third leading cause of mortality in the United States, resulting in the loss of 225,000 lives per year. Of that total, nosocomial (hospital-acquired) infections kill 80,000, physician errors claim 27,000, and unnecessary surgery results in 12,000 deaths.

Opera under the MRI

Speech Production and Articulation kNowledge Group from the University of Southern California works on very interesting projects. If you have ever wondered what vocal performance migh look like under the MRI real time, here is a video:

This video illustrates real-time MRI of vocal performance. It includes examples from a soprano and an emcee/beatboxer. This video was featured at the Sounds and Visions Session, of the International Society for Magnetic Resonance in Medicine (ISMRM) Scientific Sessions, May 2006, Seattle.

Radiopaedia: Quizzes in Radiology

A few days ago, I described how I use Quiz.MD for keeping myself up-to-date and just came across a new feature on Radiopaedia, a radiology wiki site I frequently write about. They now offer quizzes which are actually detailed, illustrated case presentations. Really useful and can also help you boost your radiology knowledge.

One example:

Colonoscopy through iPhone

Medgadget has recently featured a great application, Gyromaniac, that helps students and gastroenterologists about performing colonoscopies and what they exactly see on the monitor.

An excerpt from iMedicalApps:

A gastroenterologist fellow once jokingly told me how thankful he was for playing too many video games as a child, because it helped him learn how to perform procedures faster. I wouldn’t be surprised if there is actual truth to the statement. An app called Gyromaniac is an example of how the iPhone 4′s new gyroscope feature could actually help physicians practice spatial orientation.

Here is how Steve Jobs described this technique:

Teaching Radiology on iPhone

I’ve been writing about Radiopaedia.org, the best radiology wiki managed by Dr Frank Gaillard, for years. And now new teaching files are also available on iPhone. An excerpt from the press release:

Radiopaedia.org is proud to announce the arrival of its iPhone application, ‘Radiology Teaching Files
Version 2.0’.

Radiopeadia.org is the most comprehensive on-line knowledge-sharing tool and learning resource for
the global radiology community.

As an extension of this mission, Radiopaedia’s Radiology Teaching File now available as an iPhone
application, provides access to this global knowledge bank anytime, anyplace, from the convenience of
their iPhone. The app, like the Radiopaedia.org website, includes comprehensive discussion and sample
reports and links to additional online content.

Here are some screenshots that give you a glimpse about how it actually works.

Scan Your Sample Under an Electron Microscope

I’ve recently received an e-mail from ASPEX that offers Scienceroll.com readers the opportunity to scan a sample of their choice with an electron microscope (Desktop SEM) for free. Here are a few examples.

What you have to do:

  • Fill out the form and mail it along with the sample you want scanned to:
ASPEX Corporation

Free Sample Submissions
175 Sheffield Dr.
Delmont, PA 15626
  • Once ASPEX has completed the scan, the images and report will be posted on ASPEX’s website here.
  • It should take about 2 weeks for the results to post to the ASPEX website, and submitters will be notified via email. Samples scanned for free will not be returned.

MRI Puzzle

What happens if you combine magnetic resonance imaging with games and creativity? See the idea of Neil Fraser:

Human Body as a Machine: Video

Fritz Kahn, a German gynaecologist born in 1888, was a real genius of medical illustrations.  More than a hundred years later Henning Lederer, audiovisual artist, paid tribute to this genius by creating the video below based on Kahn’s work. Enjoy:

From 2D MRI to 3D XBOX

Magnetic resonance imaging opened a new chapter in the history of medical diagnostics, but it still cannot answer all the questions. Researchers at the Iowa State University came up with a wonderful solution. They developed a software, BodyViz, that can convert common 2D MRI and CAT scans into 3D visualizations, enabling physicians to navigate inside the body using an Xbox controller.

Two-dimensional imaging technologies have been used in medicine for a long time, said  (BodyViz co-founder) Eliot Winer, an Iowa State associate professor of mechanical engineering and an associate director of Iowa State’s  Virtual Reality Applications Center. But those flat images aren’t easily read and understood by anybody but specialists.

“If I’m a surgeon or an oncologist or a primary care physician, I deal with patients in 3-D,” Winer said.

(The creators) like to quote a doctor who told a reporter that when preparing for complex procedures, “2-D is guessing and 3-D is knowing.”
