    Announcement: Will Host Medicine 2.0 Blog Carnival about Web 2.0 and Medicine

    Friday 21st of November 2008 10:33:24 AM

    Medicine 2.0 is a bi-weekly blog carnival which collects some of the most interesting posts about Web 2.0 and Medicine. The archive is available here.

    A blog carnival is a blog event similar to a magazine dedicated to a particular topic. Each edition of a blog carnival is in the form of a blog article that contains links to other blog articles on the particular topic. According to Wikipedia, "Web 2.0 is a trend in World Wide Web technology, and web design, a second generation of web-based communities and hosted services such as social-networking sites, wikis, blogs, and folksonomies, which aim to facilitate creativity, collaboration, and sharing among users. "

    I will be hosting the next edition of Medicine 2.0 at Clinical Cases and Images - Blog. Please submit your links to clinicalcases@gmail.com.

    My last hosting is here: Medicine 2.0, Blog Carnival About Web 2.0 and Medicine, Year 1, Issue 9

    Last time, I used Google Presentations to show the links (see below) and I will add a word cloud to plug in all blog submissions this time.



    An example of word cloud:


    The word cloud of food allergen avoidance shows the frequency of term use in that article.

    I added a #Medicine2.0 hash tag on Twitter and you can find all related post there as well.

    Google SearchWiki: make search your own

    Friday 21st of November 2008 06:47:17 AM

    According to Google, "SearchWiki is a way for you to customize search by re-ranking, deleting, adding, and commenting on search results. With just a single click you can move the results you like to the top or add a new site. You can also write notes attached to a particular site and remove results that you don't feel belong. These modifications will be shown to you every time you do the same search in the future. SearchWiki is available to signed-in Google users. We store your changes in your Google Account."



    SearchWiki sounds like a good idea and I am planning to use it. I run 2 browsers most of the time:

    1. Firefox with Gmail, Blogger, Reader, and other Google services, and Twitter. I am logged in a Google account in Firefox which means that I will see the SearchWiki results.

    2. Opera for general browsing such as CNN, YouTube, etc. I am not logged in a Google account in Opera which means I will be able to see the "generic" Google results that are available to most users.

    Thursday 20th of November 2008 03:21:00 AM


    Screenshot of Renal Fellow Network

    Renal Fellow Network (http://renalfellow.blogspot.com) is "a website written for renal fellows by renal fellows with one new "Nephrology Teaching Point" posted on a daily basis.

    It is a forum with the intention of making Nephrology fellowship everywhere a more educational experience."

    The blog was started in April 2008 and most articles are signed by Dr. Nathan Hellman who also has a personal blog.

    Nathan links to the Nephrolog y Cases section at Clinical Cases and Images.

    I wish more fellows had the time, energy, and skills to maintain a specialty blog. Good luck to the founders in this new endeavor.

    LIFE photo archive hosted by Google includes millions of images, many historical medical photographs

    Wednesday 19th of November 2008 03:32:00 AM



    The LIFE photo archive is hosted by Google which allows you to search millions of photographs stretching from the 1750s to today.

    According to Google, "only a very small percentage of these images have ever been published. The rest have been sitting in dusty archives in the form of negatives, slides, glass plates, etchings, and prints. We're digitizing them so that everyone can easily experience these fascinating moments in time. Today about 20 percent of the collection is online; during the next few months, we will be adding the entire LIFE archive ? about 10 million photos."

    According to Google Blogoscoped, "as many photos are quite old, this also means many should have passed into the public domain zone, meaning you may be allowed to copy, edit, and republish that portion of the photos any way you like, including for commercial uses. Wikipedia says that ?the copyright in a published work expires in all countries ... when ... The work was created and first published before January 1, 1923, or at least 95 years before January 1 of the current year, whichever is later.?

    A few examples of image searches for medical terms are linked below - click to see the photos:

    - heart attack, for example, Vice President Richard M. Nixon visiting Senator Lyndon B. Johnson at Bethesda Naval Hospital after Johnson's heart attack.

    - cough

    - bronchitis

    - allergy

    - diabetes

    - headache

    Tips for Medical Bloggers on Blogger.com: Topic sections on the blog front page rather than random posts in reverse chronological order

    Tuesday 18th of November 2008 03:09:00 AM

    A physician blogger asks: "I would like to put a book review section in by itself. I would really like it to look more like sections on the front page of a newspaper that I could add to separately than one big long blog of such disparate topics."

    There are several ways to do this:

    1. "Future date" posts always show on the front page.

    Fix the number of posts on the front page, for example, to seven (7). Only those posts will show on the front page and they will be your topic sections. Publish the "topic section" posts. Then go back to edit them and change the date to a year in the future, for example, 2011. Then you can keep posting to your blog as usual. The RSS feed will update but only the 7 fixed "future date" posts will show on the front page.

    See an example here: http://allergycases.org/

    More on the topic:

    "I use Google Blogger to publish not only blogs (with posts in reverse chronological order) but also "regular" websites in which the article at the top of the page is not always the newest one. To do this, I often choose a date in the future (for example, 2010) which makes the desired post to stay on top. The "scheduled post" Blogger update eliminated this option but fortunately, there is a workaround:

    "We know that some bloggers currently use future post dates in order to keep one post at the top of their blog for a while. Though we recommend that you use a Text page element for this, you can still get this old behavior with just one additional step. First, publish your post with the current date and time. This will publish it to your blog. Then, once it?s published, edit the post to change the date to the future and publish it again. We don?t re-schedule posts that are already published, so the post will stay on your blog but sort to the very top."

    How to Use (and Stop Using) Scheduled Posts in Google Blogger

    2. Add "text element" to your Blogger sidebar. The text will always show in the sidebar:

    Layout Guide. Blogger Help.

    3. Use a 3-column template.

    To make your blog look more like a newspaper front page, you can use a 3-column template, in addition to the 2 tips explained above.

    In any case, the use of a wider (stretch) template is recommended, for example, Minima Stretch.

    Pericallosal Lipoma-MRI

    Monday 17th of November 2008 04:30:00 AM

    This is a rare congenital lesion characterized by the presence of fatty deposits in inappropriate places in the central nervous system The embryological derangement that leads to the formation of lipomas is still debated; lipomas are variously considered to be the result of mesodermal inclusion due to dysraphism, hyperplasia of normal leptomeningeal fat cells, heterotopia of displaced dermal anlage or derivatives from the embryological meninx primitiva(most accepted theory). Common locations are pericallosal, quadrigeminal cistern, hypothalamic suprasellar and cerebellopontine regions usually asymptomatic but can present with seizures, headache and behavioural disturbances. can be associated with callosal abnormalities. Pericallosal lipoma is usually located within the interhemispheric fissure along the corpus callosum , and on the basis of MR imaging findings in adults and children, these lesions are classified as one of two types . The tubulonodular form is round, more than 2 cm in size, and is usually located at the genu area of the corpus callosum. The second form, on the other hand, is curvilinear; thin and elongated, it is less than 1 cm in diameter and is usually found more posterior to the corpus callosum. The former has ben more associated with callosal anomalies association with pericallosal lipomas include midline defects (cleft lip or palate, median cleft nose, hypertelorism, cerebellar vermis defects, frontal lipomas) and dysraphism (myelomeningocele, encephalocele, anomalies of the cervical spine, cranium bifidium, or other calvarial defects).
