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.

Over 1000 cases of illness have now been identified in a foodborne salmonellosis outbreak that began in mid-April 2008 in the United States.

As of July 8, the Centers for Disease Control and Prevention (CDC) has reported 1013 confirmed infections throughout the United States, along with four cases in Canada. 203 hospitalizations have been linked to the outbreak. It has caused at least one death, and it may have been a contributing factor in another. The pathogen responsible is the rare Saintpaul strain of Salmonella enterica.

Nearly half of the reported illnesses were in Texas and New Mexico. According to unnamed sources close to the investigation, most illness clusters in the outbreak involve Mexican restaurants. Illness clusters in the hard hit state of Illinois were publicly identified by local health departments as involving three Mexican restaurants.

The CDC is in the process of investigating the outbreak and trying to identify the contamination’s point of origin. The U.S. Food and Drug Administration (FDA) currently suspects that the contaminated food product is an ingredient in fresh salsa, such as fresh jalapeño pepper, fresh serrano pepper, fresh cilantro, or certain types of raw tomato.

Some produce industry insiders doubt that fresh produce is to blame for the outbreak. They point to the absence of Salmonella on all of the tested produce samples to date, as well as divergent results from produce tracebacks. They also say that the extended time frame of new sicknesses makes it unlikely that either raw tomatoes or fresh jalapeños, the government’s two main suspects, could be responsible. Will Steele, President and CEO of Frontera Produce, said that “the outbreak is probably related to processed goods and they’re looking in the wrong closets.”

Steele’s Texas based company has been forced to hold shipments of fresh jalapeño peppers after loads of produce were repeatedly flagged by the FDA for testing. Although independent testing of both loads showed no sign of Salmonella, the peppers are still on hold until the FDA finishes its own testing of the second load flagged on July 1st. “There are still no results,” Steele says. “The salability of that produce in two to three days is gone. We ceased harvesting. There is no sense in bringing in more product and having it rot.”

Steele, like others in the produce industry, believes that the FDA should be focusing on processed produce instead of fresh produce. “Methodology is backward,” he says. “FDA is reaching for answers. You can’t tie jalapeño pepper shipped on June 30 back to April 10.”

Still, the FDA and the CDC consider testing of fresh jalapeños and other fresh produce a high priority. The CDC writes that “the accumulated data from all investigations indicate that jalapeño peppers caused some illnesses.”

The FDA is cautioning that people who would be in the most danger if infected with Salmonella (infants, the elderly, and those with compromised immune systems) should avoid eating the suspected types of produce listed on their website.

The Swedish organization Antipiratbyrån (The Swedish Anti-Piracy Bureau) suffered a massive blow today when the Swedish government’s Data Inspection Board stated that the Bureau’s storage of Internet user’s IP addresses is illegal.

Antipiratbyrån is an organization representing the movie and software industry in Sweden, working to protect the intellectual property of its beneficiaries. This spring they started collecting IP-addresses of suspected copyright infringers. They used the collected information to press charges and to contact the suspect’s Internet service providers, demanding repercussions.

The Data Inspection Board’s press release established that the collection of IP-addresses is in fact a violation of the Swedish Personal Data Law, prohibiting electronic storage of information about individuals without their consent.

– If they don’t cease with the activities we might follow up with a penalty order, the supervising director Britt Marie Wester at the Data Inspection Board says to TT.

Both the Swedish organization Piratbyrån – celebrating the verdict as a great victory – and the CEO of Jens of Sweden – a Swedish manufacturer of MP3-players – have stated that they might file a class action suit against the Anti-Piracy Bureau, together with the individuals registered.
