Littmann Electronic Stethoscope lets docs record, analyze heart rhythm
We didn't even know there was such a thing as an "auscultation workflow" until we first encountered the FreedomScope, a Bluetooth-packing untethered stethoscope. The 3M Littmann Electronic Stethoscope also relies on Bluetooth for wireless communications, but its purpose is somewhat different. While it looks (and for the most part acts) just like a normal stethoscope, it also has noise canceling / sound augmenting technology alongside the ability to record heart and lung sounds, which may then be analyzed using the bundled Zargis StethAssist software. It's a bit on the pricey side at $379, but should be welcomed with open arms by collaborating diagnosticians and avant-garde concert bootleggers. [Via MSN Money; Thanks, Will]
BrainPort lets you see with your tongue, might actually make it to market
We first saw the crazy BrainPort in 2006, but the intervening time hasn't been wasted by its developers, who've brought the quirky visual aid to the cusp of commercial viability. If you'll recall, the device translates signals from a head-mounted camera to electrical pulses that lightly zap your tongue in response to visual stimuli -- early results have shown people can regain a good bit of their spatial awareness and even read large writing. The next step is FDA approval, which is expected by year's end, meaning that the BrainPort could arrive as early as 2010. There is a steep entry fee though, with prices expected to begin at $10,000, but the very fact you'll be able to buy it is a milestone in our book. Edifying video after the break. [Thanks, Toy]
World's first 'wireless' pacemaker talks to your doctor daily, whether you like it or not (though you probably do)
In the past we've been clued in to both deadly pacemaker hackers and the development of a cloaking device to deal with that sticky situation. Now, according to Daily Tech, a woman in New York has become the first in the world to receive a pacemaker that communicates wirelessly with a monitoring service, which is in turn accessed daily by her doctor. "If there is anything abnormal," says Dr. Steven Greenberg from St. Francis Arrhythmia and Pacemaker Center, "it will literally call the physician" and notify him or her. In addition, most of the tests that were done in the doctor's office are now automated, saving everybody time and effort. There is no word yet on possible Twitter integration, but we're sure "Biz" Stone is already on it.[Via Switched]
DNA computer solves logical problems, inches closer to practical use
The world of biomolecular computing is hardly a lonely place: bacteria, enzymes, and all manner of chemicals have already been used to perform basic automated tasks. DNA computers are arguably the most advanced organic form of "autonomous programmable computing devices," with one already boasting a pretty tight game of Tic-Tac-Toe. The latest, put together by the Israeli Weizmann Institute, advances things with its ability to correctly respond to problems of logic. By feeding molecular rules and facts into the system, the researchers are able to program DNA strands to produce yes and no answers to basic questions. Programming is said to be technically identical to that used in electronic devices, with a robot compiler converting the programming language into molecular-level information. The ultimate aim of the project is to produce miniscule disease-fighting bots that can battle infections within the human body -- provided the DNA-programming drones don't go all Yul Brynner on us.[Thanks, Karl]
Microfluidic chip does 1,000 parallel chemical reactions, looks glorious
We'd never considered a career in biochemistry until we saw this wild beast of a chemical microprocessor. Microfluidic chips, used to test chemical reactions and properties, have been known to be smaller, but they've never before been quite this powerful. The result of a joint study between California State University, UCLA and China's Wuhan University, the "integrated microfluidic device" is capable of performing 1,024 in situ chemical reactions at a time, making the researcher's life, oh, about 1,024 times easier. Most importantly though, costly enzymes previously used for a single test can now be split up into hundreds and tested simultaneously, which should pave the way for exponentially faster and easier medical research. It's not clear when these will be widely available, but we're sure PhDs around the world are trying to order one as we speak.[Via medGadget]
PRIME hand injury diagnosis system takes hold of innovation prize
It may look like little more than a pegboard and a force meter at present, but the PRIME hand-strength measuring device has already won first place at the IShow innovation showcase. Its magic lies in the custom software loaded onto the appended PDA, which makes it possible to accurately and repeatably diagnose hand and wrist injuries that doctors currently test for by squeezing and prodding. The Rice University students responsible for the Peg Restrained Intrinsic Muscle Evaluator have applied for a patent and are planning to commercialize the device, so we'll be looking for it on the next episode of House.[Via Physorg]
New FpsBrain pills claim to make your eyes see games better
Listen, we're not doctors. Obviously. If we were doctors, we probably wouldn't be blogging. We'd be off doing highly lucrative doctor stuff. Still, even without years of fancy doctor schoolin', we can assure you that taking pills of any sort won't make you better at playing video games -- even when those pills are the new gamer-oriented FpsBrain Zoom "visual performance" enhancing capsules.These meds are set apart from FpsBrain's other offerings, which contain enough caffeine and guarana to allow most toddlers to tap into the Speed Force. Instead of filling you with raw energy, Zoom allows you to actually see better during your lengthy Halo 3 sessions, providing you with the ocular edge that ... aw, screw it. Taking good care of your eyes is important, but ordering dubious pills from European countries probably isn't the best way to do so. We prefer carrots! They're crunchy, delicious and American.
Researcher plans to use GPS to study asthma triggers
You wouldn't expect GPS tech to have an impact on asthma research, but the University of Wisconsin-Madison's David Van Sickle says it will -- he's planning on tagging sufferers so he can learn when and where they reach for their inhalers. The data will hopefully make sorting out environmental triggers of the disease much easier -- it took scientists eight years to prove that soybean dust near the Barcelona harbor caused a massive asthma outbreak in the 80s, a timeline that might have been dramatically shorter if location information had been available from the start. The plan's still in the early stages, but would-be participants can sign up already -- let's just hope the tracker is slightly more attractive than Kogan's enormous watch unit.[Via CNET]
SimMan 3G patient simulator will undoubtedly creep you out
Look, we want the next generation of robot doctors to be as competent as possible; after all, it's them that'll likely be taking care of us when our fingers lock up and our cranium-housed SSDs finally fail. That said, we can't help but be freaked completely out by Laerdal's latest and greatest patient simulator, the SimMan 3G. This almost-human can be programmed with various practice scenarios for to-be doctors to hone their skills on, and as any sophisticated mannequin should, this one is also wireless, self-contained and able to withstand four hours of surgery before conking out. We have no clue how many thousands this thing will set HOSA clubs around the nation back, but anything that bleeds, winks, and secretes shouldn't be something you "buy," anyway.
European Parkinson's patients receive first Libra DBS implants to help alleviate symptoms
St. Jude Medical's announced that patients from Austria, Germany, and Greece are among the first to be implanted with Libra Deep Brain Stimulation (DBS) devices to alleviate the symptoms of advanced Parkinson's Disease. Specifically, it's able to reduce akinesia, rigidity, tremor, and motor complications associated with taking levodopa.The company's touting Libra and LibraXP as having the longest-lasting battery of any DBS in their class, meaning potentially less surgical procedures needed for for when they gotta be replaced. No word on when they'll be expanding use of the device, but we're sure it's coming.[Via Medgadget]
Videogame training may improve eyesight, no word on the health benefits of Mind Flex
You know, the benefits of videogames just keep adding up. According to a study published in Nature Neuroscience, video game training may help people improve contrast sensitivity, or the ability to differentiate between shades of gray. Among the two groups studied, the most improvement was noted among folks who played games which required precise, visually guided aiming actions, such as Call of Duty 2 and Unreal Tournament 2004. "When people play action games," said Daphne Bavelier, a professor of brain and cognitive sciences at the University of Rochester, "they're changing the brain's pathway responsible for visual processing. These games push the human visual system to the limits and the brain adapts to it, and we've seen the positive effect remains even two years after the training was over." Now that we've established that the Xbox can be part of a healthy lifestyle, it would be irresponsible of us not to play it more often.[Via CNet]
Sony responds to 'PlayStation Palm' diagnosis
MCV asked Sony about this PlayStation palmar hidradenitis thing and a spokesperson responded, stating, "We would not wish to belittle this research and we will study the findings with interest, but this is the first time we have ever heard of a complaint of this nature." Hey, that makes two of us!The Sony spoksperson went on to say that "with any leisure pursuit there are possible consequences of not following common sense, health advice and guidelines, as can be found within our instruction manuals." We agree, but we also feel the need to play devil's advocate: Sony, it's not like you have anything in your instruction manual telling gamers they shouldn't lick their hands and then rub them non-stop on a PlayStation controller for an hour. Maybe if you included that, we wouldn't hear about people developing rashes on their hands from your game consoles. Regardless, we're pretty sure we found the cure anyway.
Study finds unique gaming disease 'PlayStation palmar hidradenitis'
Based on a report from BBC, it would appear researchers have discovered a disease that has hitherto gone undiagnosed by modern medicine: PlayStation palmar hidradenitis. As one might imagine, it has something to do with "PlayStation" and the "palms of your hands." See, using that controller is not only killing your (virtual) enemies, it's also killing you.According to the report, researchers emphasized the case of one 12-year-old girl who arrived at Geneva University Hospital in Switzerland with sores on her palms. She had recently struck up a fascination with a PlayStation game (sorry, the exact title isn't mentioned) and despite developing these sores, continued to play. That's when her folks brought her to the hospital. After 10 days of abstaining from the deadly activity, however, she was sore free! We're sorry, but we wouldn't call that "PlayStation palmar hidradenitis." We'd probably call it: Stop squeezing the controller like you want to break it!Our favorite line in the entire piece has to be this: "For the disorder to only affect the hands is very unusual." So, wait, you're telling us it's unusual for this so-called disease, the one that comes from using a game controller, to only affect the hands? What other body parts are interacting with your controller?[Thanks, RazorD!]
Scientists develop piezoelectric motor for medical microbots
Researchers at Monash University in Australia have developed a piezoelectric motor that's 0.25 mm wide, which they claim is 70% smaller than the smallest design out there. The Proteus motor, named after Fantastic Voyage's microscopic vessel, uses an E. coli-like flagellum to swim through the bloodstream. The goal is to one day have it power microbots that'll enter the body by injection to take photos, deliver medicine and eventually do surgery. According to lead scientist James Friend, escape would come from it returning to the point of entry or, should something break down, via a micro-catheter -- no tear ducts necessary this time.[Via Yahoo!

Wii Fit helping UK amputees lead a balanced life
Say what you will about the efficacy of Wii Fit as a fitness tool, but at least one UK hospital has found a perfect use for its balance-centric design: helping amputees adapt to walking on their new prosthetic limbs. Nintendo World Report has a piece on Seacroft Hospital in Leeds, which is using Wii Fit's mini-games in addition to traditional physical therapy.According to Seacroft senior physiotherapist, Lynn Hirst, the key usefulness of the Balance Board and games is enabling patients to tell "where they are taking their weight" in real time. Hirst credits the mini-games with helping "[patients improve] their core stability and their balance." Hey -- that sounds like a great use for a Balance Board.
Baby incubators made from Toyota 4Runner, Aunty Entity would be proud
Developing nations are often the recipients of used, donated baby incubators, as new ones cost about $40,000 each. Often lacking either the technicians or the parts to fix them, however, most of the incubators don't actually work. Enter Jonathan Rosen of Boston University's School of Management, who's ingeniously devised an incubator out of the very abundant Toyota 4Runner. The device is cobbled together using headlights as the heating source, the filters for air purification and the door alarm for emergency notification. The resulting incubator costs about $1,000 to make and can be repaired by auto mechanics, which is obviously good news for hospitals in need. The bad news? Dr. McDreamy's in the garage, "fixing" your car.
Keiko the robot patient helps train a new generation of robot doctors
Gifu University's Graduate School of Medicine, long fed up with subjecting the general public to the horrors of teaching hospitals (you've seen Scrubs, right?) has teamed up with the Mizuno Technical Institute in Japan to develop Keiko -- an interactive humanoid robot that mimics a number of neurological disorders, responding to the doctor's touch and even holding rudimentary conversations. The robot gives students the opportunity to observe and diagnose rare brain and nervous system illnesses in a classroom setting, where no one can get hurt -- not a bad idea, so long as this doesn't result in a generation of doctors who confuse "veins" with "wires."[Warning: Read link requires registration]
Cellphones containing nickel could cause rashes, loss of "game"
According to the UK's Telegraph, mobile phones are responsible for yet another one of the great terrors of the 21st century: dermatitis. Apparently, "skin specialists" have discovered that certain metals used in cellphones are causing some users to suffer inflamed, reddened, dry, blistered, and cracked skin. Sounds awesome, right? It seems that about a third of heavy talkers are sensitive to nickel -- a substance commonly found in gadgets -- which can become irritating after repeated exposure. Says Brown University's Dr. Lionel Bercovitch, "Given the widespread use of cellphones, the presence of metal in the exterior casing of these phones and the high prevalence of nickel sensitization in the population, it is not surprising that cellphones can cause allergic contact dermatitis." There's probably little you can do to out-and-out escape the problem, so we suggest full face mask whenever a call needs to be made -- also, for dinner parties.
French doctors use laser to destroy brain tumor in conscious patient
Neurosurgery with robotic assistance is getting pretty old hat nowadays, so it looks like scientists are trying to up the difficulty factor by keeping their patients awake -- a team of French doctors just completed the first successful removal of malignant brain tumor from a still-conscious patient, using a computerized laser and an MRI scanner to guide the probe. The fiber-optic laser was fed into the brain through a 3mm (.12 inch) hole in the patient's skull and guided via MRI to the tumor, where it fired for two minutes and completely destroyed the cancerous tissue. Once the tumor cells were dead, the cable was removed and the patient was allowed to return home -- all within a single day. That's pretty impressive, and it comes on the heels of 15 similar trials where five out six patients who underwent the total removal procedure were cancer-free nine months after surgery. The team says further research will cost an additional two million euros to progress, but if this technique works as well as they claim after peer review, we'd guess that money won't be hard to come by.[Via Fark]
PEAK PlasmaBlade electrosurgery scalpel gets FDA approval
We're still a bit gun shy when it comes to surfing over to PEAK Surgical's website after watching that PlasmaBlade demonstration video, but a new release from the outfit affirms that said electrosurgery scalpel has just been approved for use by the US Food and Drug Administration. The "tissue dissection system," as it's so gruesomely called, has been given 501(k) clearance, meaning that PEAK can now market its tool for use in general surgery. So, anxious to camp out and be the first in the country to get sliced and diced by one of these? Bombard your local hospitals with phone calls starting next month.[Via MedGadget]
