A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.
If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.
There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”
There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

Blow out sales prices likely on mattresses as new U.S. fire-resistant standards take effect
Wednesday, June 20, 2007
If you are in the market for new bedding, and not too concerned with the new United States guidelines for mattress fire resistance, now might be a good time to buy. Mattresses sold in the U.S. must meet new federal guidelines for flammability starting on July 1.

The flammability of mattress sets sold in the U.S. is subject to a new mandatory federal regulation requirement passed by the Consumer Product Safety Commission (CPSC) on February 16 last year. The requirement, costing mattress manufacturers an estimated $100 million to meet, is scheduled to take effect on July 1. The commission anticipates that the new standards will save 270 lives and 1,330 injuries per year from mattress fires.
“We’ve passed a new open flame regulation and the whole idea behind the regulation is to make sure that if a mattress catches on fire that the fire burns slowly enough that people have enough time to get out of the house and get away,” said Hal Stratton, chairman of the CPSC
Radio and TV advertising spots are reacting to the new regulation by discounting prices on mattresses that fail to meet the new guidelines. Sales made in the mattress industry, like the automobile industry, are highly negotiable on price. The new regulation does not appear to have much “teeth” for mattresses already in the distribution pipeline, but it is a new law that is a bargaining position for potential buyers.
