Does the Karate Chop really cause unconsciousness or is it just acting?

A new study led by Mayo Clinic researchers has found that relief of pain from vertebral compression fractures, as well as improvement in pain-related dysfunction, were similar in patients treated with vertebroplasty and those treated with simulated vertebroplasty without cement injections. The article, “A Randomized Controlled Trial of Vertebroplasty for Osteoporotic Spine Fractures,” was released today in the New England Journal of Medicine. Vertebroplasty is a widely applied procedure in which medical cement is injected into the spine to relieve pain and improve function in patients who have osteoporotic fractures. This study, funded by the National Institutes of Health, was the first of its kind, using a double-blinded research model to examine the impact of vertebroplasty. “Though the medical community has been using vertebroplasty for many years, there were no research results to prove whether the efficacy of the treatment relates to the cement injections, patient expectations, or other factors,” says the study’s leader, David Kallmes, MD, a Mayo Clinic physician who specializes in radiology and neurosurgery. “The cement is a permanent medical implant, and there is some concern that it places patients at future risk for additional spinal fractures.”

Learn about Crouse Hospital’s innovative approach to caring for patients with Methicillin-resistant Staphylococcus aureus (MRSA), a common infection in hospitalized patients. It can be tougher to treat than most strains of staphylococcus aureus — or staph — because it’s resistant to some commonly used antibiotics. Crouse’s dedicated unit is devoted exclusively to the care of patients with MRSA. Here, patients and their families are treated with the utmost dignity and respect while getting the specialized care they need.

This 5 minute video produced by Dr. Coleman Martin at the Saint Luke’s Brain and Stroke Institute in Kansas City, Missouri demonstrates an angiogram (arteriogram) of brain. Catheter angiography is the basis of neurointerventional procedures. This video gives patients, students and the public a sense of how an angiogram is performed and the unique images provided by this minimally invasive medical test.

Internal Carotid Artery

EBM CORPORATION www.ebm.vc 脳血管（内頸動脈）に発症した動脈瘤をリアルに再現したレプリカ．患者のCT画像等から実寸法で３次元幾何形状を復元し，ラピッドプロトタイピング技術を駆使して薄膜シリコーンゴムでモデル成型．健常成人のもつ血管壁の柔軟性をもつ拍動機能性モデル．ここでは，FLUOSTAR蛍光粒子と３次元ステレオPIV技術を駆使して患者固有の血流パターンを時空間計測した事例を紹介する， A functional replica of cerebral artery aneurysm (internal carotid artery). The 3D patient-specific geometry was reproduced using medical imaging modalities such as CT and DSA. Then, rapid prototyping techniques were utilized to produce a silicone-rubber-made vascular model, whose mechanical properties matched those of healthy human adults. In other words, the model had a functionality for realistic pulsatile flows with physiological pressure and flow rate. Herein, we introduce the flow measurement using the replica in conjunction with FLUOSTAR fluorescent particles and3D stereo PIV techniques. Fluostar蛍光粒子（上段）と非蛍光粒子（下段）の比較．画像はオリジナルであり，画質の改善処理などは一切おこなっていない．使用した計測システムは標準ハイスピードカメラと高速パルスレーザー（Nd Movies showed FLUOSTAR particles (Top: left and right) and uncoated particles (Bottom: left and right) in PIV experiments. The images were original without any image enhancement. A standard CMOS high-speed camera and Nd:YLF laser (5 mJ/pulse) were utilized. As seen, FLUOSTAR ensured optical imaging in the near-wall region without …
