Last week, the FDA revoked its 2008 approval of the drug Avastin to treat breast cancer, concluding that the drug does little to help women with breast cancer while putting them at risk for potentially life-threatening side effects. Avastin will remain on the market (and so be potentially available to women with breast cancer) because it has also been approved to treat other types of cancer.
In a statement, FDA Commissioner Margaret A. Hamburg said this:
FDA recognizes how hard it is for patients and their families to cope with metastatic breast cancer and how great a need there is for more effective treatments. But patients must have confidence that the drugs they take are both safe and effective for their intended use. After reviewing the available studies it is clear that women who take Avastin for metastatic breast cancer risk potentially life-threatening side effects without proof that the use of Avastin will provide a benefit, in terms of delay in tumor growth, that would justify those risks. Nor is there evidence that use of Avastin will either help them live longer or improve their quality of life.

A recent announcement is likely to generate a lot of controversy. The Advisory Committee on Immunization Practices of the CDC has recommended that boys and young men be vaccinated against human papillomavirus (HPV). Previously the guidelines said boys “could” be given the HPV vaccine. Now they have recommended that boys age 11 to 12 “should” be vaccinated, as well as boys age 13 to 21 who have not already had the full series of 3 shots. The vaccine can also be given to boys as young as 9 and to young men age 22 to 26.
The vaccine was originally promoted as a way to prevent cervical cancer. Boys don’t have a cervix, so why should they be subjected to a “girl’s” vaccine? There are some good science-based reasons:
- Boys can transmit the virus to female sex partners later in life, leading to cervical cancer in women.
- More importantly, boys themselves can also be directly harmed by the virus. It can cause genital warts, cancer of the head and neck (tongue, tonsils and throat), anal and penile cancer, respiratory papillomatosis, and giant condyloma of Buschke and Lowenstein. In rare cases, immunocompromised patients can develop epidermodysplasia verruciformis.
- HPV has even been Read more »

Sheril Kirshenbaum, research associate at the University of Texas Austin’s Center for International Energy & Environmental Policy, blogged this week under the headline, “Battle Hymn of the Science Journalist.” Excerpt:
There are many excellent science journalists who inhabit the blogosphere and those mainstream news outlets that still feature science sections. These talented individuals want to share your story, your research, and they appreciate and value what you do.
However, there are also a lot of horrible journalists making the rest of us look bad.. Writers who care less about getting it right, and more about trumping up controversy. Journalists whose headlines are notoriously misleading or false. Some Read more »

We’re another step closer to integrating real time information into our vision. Researchers from the University of Washington and Aalto University Finland have engineered the first prototype of a computerized contact lens on which you can see information updates. They presented their findings today in IOP Publishing’s Journal of Micromechanics and Microengineering.
The lens only contained one pixel, but by proving that the concept works without any adverse side effects, they can develop it into lenses with more pixels. This could eventually lead to contact lenses on which you can read your email and catch up on the news. A device like this could also Read more »

For the last 4 years, I’ve been teaching medical and public health students about the use of social media and generally digital technologies in medicine and healthcare and I got a good picture of what kind of medical professionals they would become soon. They represent the new generation of physicians.
Here are my points and observations:
- They are technophile. I remember the time when there was no internet, I remember the first website I first saw online. They were born into the technology and internet-based world. For them, websites, Facebook, Twitter and blogs represent the basics. They love gadgets and devices.
- They are fast. They use smartphones, read news online, follow blogs and know what RSS is, they are familiar with multi-tasking. They are much faster than the previous generations, therefore they need different tools and solutions in their work.
- But they use the technology for Read more »
