Dutch scientists have said in a study that burning your food may lead to certain types of cancer, particularly in women. Scientists also say that more research is needed to make a definite determination and that there are other factors that could be to blame.

“This new study supports our current advice, which already assumes that acrylamide has the potential to be a human carcinogen. Since acrylamide forms naturally in a wide variety of cooked foods, it is not possible to have a healthy, balanced diet that avoids it,” said a Food Standards Agency spokesperson.

According to the study, acrylamides, a chemical produced when cooking foods high in carbohydrates over 120 degrees Celsius (248 degrees Fahrenheit) in the frying, toasting and grilling processes, is a likely cause of some womb and ovarian cancers. Although it was found in 2002 that the chemical may be a cause of some cancers, the new study shows, for the first time, a link between the chemical in a human diet being a cause. To date, there is no evidence to suggest the chemical may cause breast cancer.

Scientists followed and monitored 120,000 people over an 11-year-period, of whom 62,000 were women. Of the women, 300 ended up contracting ovarian cancer with 327 contracting womb cancer.

The study concluded that more than 40 micrograms of the chemical, or one bag of potato chips per day, is twice as likely to cause cancer in women.

“General advice, resulting from this project, is to avoid overcooking when baking, frying or toasting carbohydrate-rich foods,” said a spokesman for the European Union.

Japanese multinational company Fujitsu launched a website for a dog pedometer which allows customers to monitor their dog’s health online. The device measures data while attached to the dog’s collar. Customers are also able to add more data to the website manually, then it displays the complete set of data graphically. Fujitsu launched the website today (Tuesday) and plans to start the sales in Japan tomorrow (Wednesday).

The pedometer is called “Wandant”, from Japanese “Wan” equivalent to “woof”, and the “dant” of “pendant”. The latter refers to the pedometer, because it is attached to a dog collar. The users can transfer data to an Android phone using a touch-card to make it available online.

Fujitsu said Wandant would be the first cloud-based dog health-care service.

The data include walking, temperature, and shaking motion statistics. The users can manually enter additional data such as food quantities, weight, custom notes, and photos.

Fujitsu said, “The data are presented graphically on a custom website that makes trends in the dog’s activities easy to understand at a glance. This helps owners get a stronger sense of their dog’s health, while enabling communication with the dog.”

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.

Tuesday, March 29, 2005A team of Australian surgeons yesterday reattached both hands and one foot to 10-year-old Perth boy, Terry Vo, after a brick wall which collapsed during a game of basketball fell on him, severing the limbs. The wall gave way while Terry performed a slam-dunk, during a game at a friend’s birthday party.

The boy was today awake and smiling, still in some pain but in good spirits and expected to make a full recovery, according to plastic surgeon, Mr Robert Love.

“What we have is parts that are very much alive so the reattached limbs are certainly pink, well perfused and are indeed moving,” Mr Love told reporters today.

“The fact that he is moving his fingers, and of course when he wakes up he will move both fingers and toes, is not a surprise,” Mr Love had said yesterday.

“The question is more the sensory return that he will get in the hand itself and the fine movements he will have in the fingers and the toes, and that will come with time, hopefully. We will assess that over the next 18 months to two years.

“I’m sure that he’ll enjoy a game of basketball in the future.”

The weight and force of the collapse, and the sharp brick edges, resulted in the three limbs being cut through about 7cm above the wrists and ankle.

Terry’s father Tan said of his only child, the injuries were terrible, “I was scared to look at him, a horrible thing.”

The hands and foot were placed in an ice-filled Esky and rushed to hospital with the boy, where three teams of medical experts were assembled, and he was given a blood transfusion after experiencing massive blood loss. Eight hours of complex micro-surgery on Saturday night were followed by a further two hours of skin grafts yesterday.

“What he will lose because it was such a large zone of traumatised skin and muscle and so on, he will lose some of the skin so he’ll certainly require lots of further surgery regardless of whether the skin survives,” said Mr Love said today.

The boy was kept unconscious under anaesthetic between the two procedures. In an interview yesterday, Mr Love explained why:

“He could have actually been woken up the next day. Because we were intending to take him back to theatre for a second look, to look at the traumatised skin flaps, to close more of his wounds and to do split skin grafting, it was felt the best thing to do would be to keep him stable and to keep him anaesthetised.”

Professor Wayne Morrison, director of the respected Bernard O’Brien Institute of Microsurgery and head of plastic and hand surgery at Melbourne’s St Vincent’s Hospital, said he believed the operation to be a world first.
