New prostate surgery not necessarily better: study

Men who have less invasive prostate cancer surgery — often done robotically — are more likely to be incontinent and have erectile dysfunction than men who have conventional open surgery, U.S. researchers said on Tuesday.

Many men, especially those who are wealthy and highly educated, favor minimally invasive surgery because they assume the high-tech approach will yield better results, but the evidence on that is mixed, the team reported in the Journal of the American Medical Association.

“We found men undergoing minimally invasive versus open surgery were more likely to have a diagnosis of incontinence and erectile dysfunction,” Dr. Jim Hu of Brigham and Women’s Hospital in Boston said in a telephone briefing.

Hu said use of minimally invasive surgery has taken off since the introduction and heavy marketing of robot-assisted surgery, such as the da Vinci system made by Intuitive Surgical Inc.

The system consists of robotic arms, controlled from a console, that allow surgeons to perform less invasive surgeries. Hospitals advertise the systems as being able to reduce trauma, blood loss, risk of infection, scarring and often pain.

Hu said so far, there have been few studies that compare minimally invasive surgery with open surgery.

To do that, he and colleagues used billing data from the Medicare insurance program for the elderly on procedures done from 2003 to 2007. During that time, use of minimally invasive surgery for prostate cancer increased fivefold.

While both approaches fared equally well as a cancer treatment, they found that men who got the minimally invasive approach had shorter hospital stays, were less likely to need blood transfusions, and had fewer breathing problems after surgery than those who got conventional surgery.

Cell Phone Cancer

Myth: Cell phones cause brain cancer

Lawsuits and news headlines have fueled the myth that cell phones cause cancer, particularly brain cancer, and 30 percent of Americans still believe this myth, according to the Discovery Health/Prevention telephone survey. Consumers could easily have missed the reports showing no danger from cell phones because they didn’t receive alarming front-page coverage like the original reports. A few studies suggested a link with certain rare types of brain tumors, but the consensus among well-designed population studies is that there is no consistent association between cell phone use and brain cancer.

Interesting Fact:The very first patent for a cell phone like device (wireless telephone) was granted in 1908 to Nathan B. Stubblefield who some people claim invented the radio before Tesla and Marconi. Stubblefield died as a self-imposed hermit by starving to death.

Pesticides ‘linked to Parkinson’s’

Pesticides ‘linked to Parkinson’s’

A pesticide is a substance or mixture of substances used to kill a pest.[1] A pesticide is any substance or mixture of substance intended for: – preventing, destroying, repelling or mitigating any pest.[2] A pesticide may be a chemical substance, biological agent (such as a virus or bacteria), antimicrobial, disinfectant or device used against any pest. Pests include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), microbes and people that destroy property, spread or are a vector for disease or cause a nuisance. Although there are benefits to the use of pesticides, there are also drawbacks, such as potential toxicity to humans and other animals.

2,4-Dichlorophenoxyacetic acid – known as 2,4-D – used to kill a range of weeds

Permethrin – used in pest control, including ant powder and flea killer. Sprayed on tents and nets to repel mosquitoes

Paraquat – weedkiller used on a range of crops including potatoes. Banned for use in Europe since 2007

Dieldrin – pesticide, banned for use in Europe

Diquat – general weedkiller

Maneb – kills fungus, used to protect potatoes, tomatoes and other crops

Mancozeb – also kills fungus, used to protect potatoes among other crops

Rotenone – used to eradicate unwanted fish species as well as other pests
