Continuing this week’s spontaneous theme (we didn’t make the claims and write the stories) of runaway enthusiasm for various screening tests by some researchers and journalists, HealthDay news service has reported on a study published in the Oct. 28 issue of the journal Nature that they say “provides new insight into the genetics of pancreatic cancer.” In the story, they let one of the researchers get away with saying, almost unchallenged:
“What’s important about this study is that it’s objective data in support of why everyone should be screened for pancreatic cancer.”
Mind you, this was a study that looked at tissue from just seven patients. The story continued with its breathless enthusiasm for the pancreatic cancer screening idea:
“In the future, new imaging techniques and blood tests will offer hope for early detection, the study noted. And just as people have a colonoscopy when they turn 50, “perhaps they should have an endoscopy of their upper gastrointestinal organs that includes an ultrasound of the pancreas,” said (the researcher).”
The very end of the story included some skepticism from Dr. Len Lichtenfeld of the American Cancer Society. Read more »

Antioxidants are important substances that prevent free radicals from damaging cells, and potatoes contain substantial amounts of them.
However, researchers from Obihiro University in Japan thought that more would be better and have developed some innovative methods of boosting the potato’s antioxidant content. By immersing the potatoes in water or salt and subsequently applying ultrasound or electricity for 5 to 30 minutes, they increased the amounts of antioxidants by as much as 50 percent. Read more »

Finally men everywhere might have a birth control option that won’t rob them of the joys of living.
Scientists at the University of North Carolina at Chapel Hill may have discovered a cheap, convenient and noninvasive method of male birth control — ultrasound. The scientists believe that a single treatment can provide up to six months of infertility that is reversible.
The team has received a $100,000 Grand Challenges Explorations grant from the Bill and Melinda Gates Foundation for their work. If the project pans out, this could have an incredible impact on global health. Read more »

What Shari Welch Said.
Ultrasound is a neat toy, and I’m all about toys. I found two opportunities to play with enhance patient care with our ultrasound today on my shift. But it doesn’t have the bang for the buck that the enthusiasts think it does. It has very narrow, but real, utility, and does nothing to generate revenue. It does in some cases enhance patient turnaround, and it certainly enhances patient satisfaction (they love cool toys as much as we do — and extra face time with the doctor to boot!). But that’s a small return on a machine costing tens of thousands of dollars. Read more »

As we wrote yesterday, GE released a handheld ultrasound system unlike any other. Yesterday, at a GE press conference in New York, we saw the device first hand and we brought a video back of a company rep demonstrating its use. At 3 inches wide, 5.3 inches long, and about an inch high, the device already has FDA and European approval. GE plans to first conduct a real world study of how the Vscan will be used by clinicians before releasing it to the general market. Read more »
