Medical Procedures: How “Gamma Knife” Surgery Treats Brain Tumors

It’s called gamma knife surgery, but there’s no cutting involved. It’s been used at Mayo Clinic for 30 years as an alternative to open brain surgery.

The patient’s head is held still during the procedure with a headframe, which also serves as a map for the radiation. Using 3D imaging — typically an MRI — as a guide, the gamma knife is targeted directly at the tumor. And with no hospital stay and minimal side effects, it’s a procedure that is efficient and can be lifesaving.

Top New Science Podcasts: Lack Of Clinical Trial Reporting, Gut Microbe Links To Chronic Disease

Science Magazine PodcastsThough a law requiring clinical trial results reporting has been on the books for decades, many researchers have been slow to comply. Now, 2 years after the law was sharpened with higher penalties for noncompliance, investigative correspondent Charles Piller took a look at the results. He talks with host Sarah Crespi about the investigation and a surprising lack of compliance and enforcement.

Also this week, Sarah talks with Brett Finlay, a microbiologist at the University Of British Columbia, Vancouver, about an Insight in this week’s issue that aims to connect the dots between noncommunicable diseases like heart disease, diabetes, and cancer and the microbes that live in our guts. Could these diseases actually spread through our microbiomes?

Medical: “Mohs Micrographic Surgery” For Skin Cancer Explained

Named after the late Frederic Mohs, M.D., Mohs micrographic surgery is a highly precise excision technique in which the cancer is removed in stages, one tissue layer at a time. After each removal step, the layer is examined under a microscope to determine whether cancer remains in the patient’s skin and, if present, where exactly it is located so that the surgeon can pinpoint where to remove the remaining skin cancer. This allows for the smallest scar and best cosmetic result.
