Donor kidney removed via vagina

US surgeons say they have successfully removed a healthy donor kidney through a small incision in the back of the donor's vagina.

Removing the kidney through "a natural orifice" speeds up recovery and gives a better cosmetic result - avoiding a six inch abdominal scar - they say.

The Johns Hopkins team say the 48-year-old woman who donated the organ to her niece on 29 January is "doing well".

Surgeons have also removed gallbladders and appendixes through the mouth.

Diseased gallbladders, kidneys and appendixes have been removed through the vagina before.

But this is believed to be the first time that doctors have managed to harvest a healthy donor kidney for transplantation in this way...

Oddball museums around the world

If "Night at the Museum" had been set somewhere other than New York’s Museum of Natural History, it would be a very different movie. This 2006 blockbuster starring Ben Stiller made hundreds of millions of dollars and, reportedly, boosted museum attendance. But it could have been a much stranger beast. Instead of Teddy Roosevelt and Pocahantas, one night in Philadelphia’s Mutter Museum could've led to a romance between Siamese twin skeletons and the corpse of an obese woman whose fat has turned to soap. At the Venthaven ventriloquist museum, the big laughs could've given way to the scariest "Twilight Zone" episode ever.

World-class museums aside, a lot of people find second-rank museums lacking. At best, they're hermetically sealed repositories of dusty culture; at worst, they're tourist traps teeming with children on field trips. Sometimes, you gotta take a walk on the weirder side.

Doug Kirby, publisher of the book series and Web site Roadside America, has catalogued bizarre museums and other attractions best avoided by elementary school field trips. By heading off the beaten path, he says, “you’ll see amazing things—but just duck your head and make sure your tetanus shot is up-to-date”...

Body's Own 'Cannabis' Is Good For The Skin, Scientists Find

Scientists from Hungary, Germany and the U.K. have discovered that our own body not only makes chemical compounds similar to the active ingredient in marijuana (THC), but these play an important part in maintaining healthy skin.

This finding on "endocannabinoids" just published online in, and scheduled for the October 2008 print issue of, The FASEB Journal could lead to new drugs that treat skin conditions ranging from acne to dry skin, and even skin-related tumors.

"Our preclinical data encourage one to explore whether endocannabinoid system-acting agents can be exploited in the management of common skin disorders," said Tamás Biró, MD, PhD, a senior scientist involved in the research. "It is also suggested that these agents can be efficiently applied locally to the skin in the form of a cream."

Biró and colleagues came to this conclusion by treating cell cultures from human sebaceous glands (the glands that make the oil on our skin) with various concentrations of endocannabinoids (substances produced by the body that are similar to the active ingredient in marijuana)...

Genetic Discrimination Ban Clears House; Senate OK Expected

If legislation passed Wednesday by the House of Representatives becomes law, it will be illegal to deny a job or health insurance on the basis of a person's genetic makeup.

With more links drawn between genetic profiles and disease predispositions every day, supporters of the Genetic Information Nondiscrimination Act say the bill will ease patients' worries of being singled out for faulty genes.

“GINA will do more than stamp out a new form of discrimination,” said Louise Slaughter (D-New York) who introduced the bill. “It will allow us to realize the tremendous potential of genetic research without jeopardizing one of the most fundamental privacies that can be imagined.”

Such discrimination is rare, but supporters of the bill worry that as genetic testing becomes common and scientists chart the complex links between genes and health, profiling might also increase...

Flagellation ritual exposes Filipinos to rabies

More than a hundred men in the Philippines may have contracted rabies after taking part in a self-flagellation ritual to mark Good Friday, doctors and local authorities said on Thursday.

A health alert was issued after a man who took part in the traditional ceremony – where participants slash their backs with knifes before flaying themselves with bamboo whips – died from the virus on 11 April.

Mario Morales, the mayor of Mabalacat in Pampanga province north of Manila, told local media that Eduardo Sese may have contaminated up to 100 people who shared knives to cut themselves. He was bitten by an infected dog in February 2007.

The government doctor in Pampanga, Maria Clara Aquino, said vaccines had been given to 103 people who could have been exposed...

Creepy-crawly robot to mend a broken heart

A device that sounds like a 21st-century version of a medicinal leech may soon be set loose inside the chests of heart patients. Resembling a robotic caterpillar, it will crawl across the surface of their beating heart, delivering treatment without the need for major surgery.

The device, called HeartLander, can be inserted using minimally invasive keyhole surgery. Once in place, it will attach itself to the heart and begin inching its way across the outside of the organ, injecting drugs or attaching medical devices. In tests on live pigs, the HeartLander has fitted pacemaker leads and injected dye into the heart. This video shows the latest prototype creeping over the surface of a beating model heart (2.1MB, mpg format).

The 20-millimetre-long robot has two suckers for feet, each pierced with 20 holes connected to a vacuum line, which hold it onto the outside of the heart. By moving its two body segments back and forth relative to one another it can crawl across the heart at up to 18 centimetres per minute. This back-and-forth movement is generated by pushing and pulling wires that run back to motors outside the patient's body. The robot is being developed by Cameron Riviere and colleagues at Carnegie Mellon University in Pittsburgh, Pennsylvania...
