Anyone in the USA can purchase a gun in the USA unless they are a felon. When you buy a gun do you automatically know how to use it responsibly? NO. You must take a gun safety course to learn to use it for hunting or self defense. The same is true for an ultrasound machine. You get a day of apps from the manufacturer, then you are on your own. Apps specialists do not train you how to do a sonogram, they show you how to operate the equipment. To learn how to use an ultrasound machine requires rigorous education and training accompanied by many patient encounters. Too many physicians and imaging facilities think the ultrasound machine is like an EKG machine: put the electrodes on the chest and let the machine do the work. I want you all to embrace ultrasound as a valid and useful tool in diagnostic medicine, but get some training on how to use the equipment! Just my thoughts. Have a great holiday weekend.

CINCINNATI—A new study from the University of Cincinnati (UC) College of Medicine has found that, when delivered via ultrasound, the natural enzyme plasmin is more effective at dissolving stroke-causing clots than the standard of care, recombinant tissue plasminogen activator (rt-PA).
The novel delivery method involved trapping plasmin into bubble-like liposomes, delivering them to the clot intravenously and bursting it via ultrasound. That method is necessary, says UC associate professor of emergency medicine George "Chip” Shaw III, MD, PhD, because plasmin cannot be delivered through traditional methods. Intravenous delivery of rt-PA is designed to solve that problem by catalyzing the conversion of existing plasminogen inside the body to plasmin, which in turn degrades blood clots.
"Plasmin is the enzyme that actually chews up the fibrin in clots,” says Shaw. "The problem is you can only give plasmin inter-arterially, which has safety risks and takes longer to deliver. IV therapy is always easier and quicker, but if you give plasmin intravenously, the body inhibits it immediately. If you can encapsulate it, it doesn’t get inhibited and you can target it to the clot.”

Under this project an advanced software system will be developed to improve detection of life-threatening internal bleeding after blunt abdominal trauma.
Clifton Park, NY (PRWEB) May 09, 2013
Kitware, a leading-edge medical imaging software provider, today announces new Phase I SBIR funding from the National Institutes of Health for the development of hardware and image analysis algorithms that will allow novice ultrasound operators to perform life-saving Focused Assessment with Sonography for Trauma (FAST) procedures.
FAST procedures are rapid ultrasound examinations for identifying abdominal hemorrhaging, which is often associated with blunt abdominal trauma (BAT). Detection of this free fluid is done via ultrasound images of four specific abdominal areas. Patients with positive FAST results are in urgent need of treatment, whereas negative results indicate more stable patients.

Pregnant women who are morbidly obese may need more time during theirultrasound appointments and more frequent visits because their babies may be difficult to image, researchers report.
"There's a real prevalence of obesity in women of reproductive age; nearly one third of women are obese." In addition, nearly 8% of these women are morbidly obese, with a body mass index of more than 40 kg/m², said Robert Ehsanipoor, MD, from the Johns Hopkins University School of Medicine in Baltimore, Maryland.

I have a brief article regarding a test that is non-invasive and which can predict a persons cardiovascular health. the Endopat test uses a pressure cuff and expensive finger sensors to evaluate a persons vascular resistance. Vascular resistance refers to the force needed to perfuse the arteries in the body by the heart. It concludes that the higher the resistance, the stiffer the blood vessels, thus the more disease prone they are. I have learned to perform this test, and will soon be testing patients in the clinic. I think it has merit in that it is FDA approved and backed by some solid research. I am not sure that I want to be told I may have a heart attack within 7 years though. I took the test myself, and scored very well. I guess that is good news.
