CT SOMATOM Emotion 6 CT Suggests King Tutankhamen Died from an Infected Leg WoundSiemens AG reports:

Using images generated by a mobile computed tomography (CT) system from Siemens Medical Solutions, experts in Egypt have examined the cause of King Tutankhamen’s death some 3,000 years ago. The CT scan of the Pharaoh’s mummy did not find evidence that Tutankhamen was murdered.
The mummy of Tutankhamen was discovered in Egypt’s Valley of Kings in 1922. An initial X-ray analysis in 1968 revealed a bone splinter embedded in the Pharaoh’s skull. This fact – coupled with the body’s obviously hasty mummification and burial – led to speculation that Tutankhamen had died from head injuries, and possibly been murdered.
The now completed CT examination, based on images generated from a total of 1,700 slices, found no evidence for this theory. But the Pharaoh may have suffered from a broken thigh shortly before his death at the age of 19. Some members of the examination team say that the Pharaoh may have died from an infection of this wound. They refer to the fact that the CT images revealed embalming resin inside the wound, and that there was no sign of a healing process. Other scientists on the team doubt that the injury was the cause of the king’s death. They believe the wound could have been inflicted later by archaeologists examining the mummy, arguing that there was no evidence for hematoma, which should be there if the injury was inflicted during the Pharaoh’s lifetime.
This examination is part of a research project being conducted by Egypt’s Supreme Council of Antiquities. The project also includes meticulous CT scans of a large number of other Egyptian mummies.
The CT system donated for the project, the SOMATOM Emotion 6, provides important prerequisites for this study: It combines advanced imaging capabilities with minimal sitting requirements. Because of its wide opening, the mummies can be positioned without difficulty. Also, it is capable of displaying the finest details in three-dimensional imaging.

Der Mensch als Industriepalast
Stuttgart, 1926. Chromolithograph. National Library of Medicine.
Fritz Kahn (1888-1968)
A fascinating online exhibit, produced by the U.S. National Library of Medicine, is our feature for this week’s “the good old days…” column.

The interior of our bodies is hidden to us. What happens beneath the skin is mysterious, fearful, amazing. In antiquity, the body’s internal structure was the subject of speculation, fantasy, and some study, but there were few efforts to represent it in pictures. The invention of the printing press in the 15th century-and the cascade of print technologies that followed-helped to inspire a new spectacular science of anatomy, and new spectacular visions of the body. Anatomical imagery proliferated, detailed and informative but also whimsical, surreal, beautiful, and grotesque — a dream anatomy that reveals as much about the outer world as it does the inner self.
Over the centuries anatomy has become a visual vocabulary of realism. We regard the anatomical body as our inner reality, a medium through which we imagine society, culture and the human condition.
Drawn mainly from the collections of the National Library of Medicine, Dream Anatomy shows off the anatomical imagination in some of its most astonishing incarnations, from 1500 to the present.

TGIF: the weekend is (almost) here! Have a great time, and thanks for stopping by! Next week is particularly exciting for us, as Medgadget’s very own Dr.O and Dr. Choi are going to go to the 2005 Excellence in Medical Devices Awards Banquet by Frost & Sullivan on March 16 in San Francisco. As we have said before, if we don’t sell our soul on that day to high power executives from the medical manufacturing industry, we will be blogging the event live.
Please also note that the site will be intermittently down throughout the weekend as we make upgrades to it.

transducer AcuNav HP4 Acuson AcuNav 8F for Intracardiac Ultrasound ExamsSiemens AG has announced that it received 510(k) clearance from the US Food & Drug Administration to market its new Acuson AcuNav 8F catheter, designed for ultrasound examinations from inside the heart.
The company describes the product:

The ACUSON AcuNav™ Diagnostic Ultrasound Catheter brings the full force of ultrasound technology inside the heart. Physicians can now perform a complete ultrasound exam when it counts most – during interventional procedures and before the patient leaves the catheterization or electrophysiology lab. AcuNav is relied upon by electrophysiologists to provide critical visualization necessary to perform atrial fibrillation and other complex arrhythmia ablations. As interventional cardiologists replace open-heart surgical closure of septal defects with transcatheter techniques, the AcuNav catheter is their visualization tool of choice, even supplanting transesophageal imaging.
AcuNav is a sterile, single-use, 10 French ultrasound catheter designed for placement inside the venous system providing ultrasound images with unparalleled detail resolution and penetration, down to 15 cm in the heart. The user determines the desired tradeoff between resolution and penetration by choosing from up to four imaging frequencies, all at the touch of a button.
The catheter is compatible with the ACUSON Sequoia™, Aspen™ and Cypress™ echocardiography systems.

The technology is becoming very cool! Not just cool, but better and better for patients as well.

rexbottlePC Rex The Talking BottleRex-The Talking Bottle, the product of MedivoxRx Technologies, Inc., is designed to improve patient compliance with their drug regiments:

People with significant health problems are often taking four or more prescription drugs at the same time, each with a different prescribed dosage, quantity or frequency. When a person cannot read or understand the label on a medication bottle, usage mistakes occur. The results of such errors can range from adverse reactions that are simply uncomfortable to untimely death.
There are two ways to record Rex:
The first is that a pharmacist types in the label information, including name of the medication, prescribed dosage, how to take it, potential side effects, etc, and Rex is simultaneously loaded with the information while the label is being printed.
The second way is that people can purchase a Rex Starter Kit for personal use, which includes a special recorder, so patients can verbally record the information themselves. Rex is then ready to communicate its contents – at home, in the car, at a restaurant, in an airplane, anywhere at all!
When it’s time to take one or more pills, the consumer simply presses a built-in button at the bottom of each “talking” container to hear the message and locate the desired medication and instructions for use. The voice labeling system in “Rex” accepts all spoken languages making this a multilingual product as well.

robotdoctor la RP 6: Now in ICUNBC 4 News from Los Angeles reports:

A robot is doing rounds at a UCLA Medical Center intensive care unit in a test of new technology.
The 5-foot, 6-inch tall RP-6 robot’s visits to the hospital’s neurology intensive care unit function as a videoconference with the live doctor, who is able to work the controls from miles away from the hospital. A screen on the robot’s head shows live images of the doctor.
Officials at the hospital say the robot will increase patients’ access to their physicians, and allow the doctors to monitor patients at anytime, even from home or offices.
Hospital officials also say the device will extend the reach of critical-care specialists, who are in high demand. Nationwide, there are fewer than 6,000 doctors who specialize in treating critically ill patients, and more than 5 million patients are admitted to ICUs each year.
A study by Johns Hopkins Hospital found that half the patients who received a virtual visit by their own doctor preferred it to a live visit from another doctor. About 80 percent said the robot made their doctor more accessible.
According to UCLA, its medical center is the first hospital to test the robot in an ICU…

Flashback: ‘Patient rounds with robodoc’

The latest research out of the University of Pennsylvania School of Medicine dispells some myths about the computerized physician order entry systems:

Health-care policymakers and administrators have championed specialty-designed software systems – including the highly-touted Computerized Physician Order Entry (CPOE) systems – as the cornerstone of improved patient safety. CPOE systems are claimed to significantly reduce medication-prescribing errors. “Our data indicate that that is often a false hope,” says sociologist Ross Koppel, PhD, of the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania School of Medicine. “Good computerized physician order entry systems are, indeed, very helpful and hold great promise; but, as currently configured, there are at least two dozen ways in which CPOE systems significantly, frequently, and commonly facilitate errors – and some of those errors can be deadly.”
As reported in today’s Journal of the American Medical Association, Koppel and colleagues studied the day-to-day medication-ordering patterns and interactions of housestaff working in a tertiary-care teaching hospital, which, at that time, ran a popular CPOE system. In addition to a comprehensive survey of almost 90% of the housestaff who use CPOE, the researchers also shadowed the doctors and pharmacists, as well as performed interviews with the hospital’s attending physicians, nurses, IT and pharmacy leaders, and administrators. As a result, they identified 22 discreet ways in which medication-errors were facilitated by the CPOE system they studied.
The significance of their findings, notes Koppel, is to serve as a wake-up call to those who would believe that hospital IT systems — such as computerized physician order entry systems — represent a simple turn-key solution to patient safety; and, in particular, the reduction of medication errors.

TracDS2 Vasotrac Non Invasive Blood Pressure MonitorMedwave, Inc. reports that its latest study, published in the American Journal of Emergency Medicine, has compared readings taken with Medwave’s Vasotrac non-invasive blood pressure monitor against the “gold standard” intra-arterial catheter and a traditional blood pressure cuff, and “… showed that Medwave’s Vasotrac monitor provided advantages over both.”
The company explains:

– Using a patented method of measuring radial artery waveforms, the Vasotrac system calculates accurate systolic, diastolic and mean pressures. Accurate, continual, and non-invasive, the Vasotrac is the most advanced clinical solution to blood pressure monitoring.
– After positioning the wrist sensor, just one keystroke is required to begin measuring arterial blood pressure. There are no complicated set-up or calibration requirements. The initial measurement and waveform are displayed in approximately 15 seconds, with continual updates four to six times a minute.
– Patients experience minimal sensation while wearing the wrist sensor. Operation is very smooth and quiet. The wrist sensor fits patients with wrist size from 11 – 22 cm, can be worn on either wrist, and is completely latex-free.

Everything is honky-dorry, of course, except that there is competition out there, as we have reported earlier. Yet another catfight to follow!
