No Mouse Is Safe: Cat Gets World’s First Bionic Paws

Oscar the cat may have lost one of his nine lives, but his new prosthetic paws make him the world’s first bionic cat.

After losing his two rear paws in a nasty encounter with a combine harvester last October, the black cat with green eyes was outfitted with metallic pegs that link the ankle to the foot and mimic the way deer antlers grow through skin. Oscar is now back on his feet and hopping over hurdles like tissue paper rolls.

After Oscar’s farming accident, which happened when the 2 1/2-year-old-cat was lazing in the sun in the British Channel Isles, his owners, Kate and Mike Nolan, took him to their local veterinarian. In turn, the vet referred Oscar to Dr. Noel Fitzpatrick, a neuro-orthopedic surgeon in Eashing, 35 miles southwest of London.

Together with biomedical engineering experts, Fitzpatrick gave Oscar two metal prosthetic implants that are a bit wobbly, to imitate a cat’s natural walk. But first, he covered the brown implants with black tape to match Oscar’s fur.

Fitzpatrick said he and biomedical engineers designed the artificial paws so that they would be fused to the bone and skin. “That allows this implant to work as a seesaw on the bottom of the animal’s limbs to give him [an] effectively normal gait,” he said. “Oscar can now run and jump about as cats should do.”

Pesticide Exposure Cause of ADHD?

This morning on AOL Health News:

By Mary Beth Sammons
In the United States alone, an estimated 4.5 million children ages 5 to 17 have been diagnosed with attention deficit hyperactivity disorder, according to the Centers for Disease Control and Prevention, and rates of diagnosis have risen 3 percent a year between 1997 and 2006. Yet it is unclear what is causing this increase. New research is investigating many avenues. One of them is environmental factors such as pesticides and allergens.

In a study published in the journal Pediatrics, researchers studied 1,139 children ages 8 to 15. All of the children studied had measurable residue of pesticides commonly used on fruits and vegetables. Diet is a major source of pesticide exposure in children, according to the National Academy of Sciences, and much of this exposure comes from the common kid-friendly fruits and vegetables, such as blueberries, strawberries and celery. In a 2008 government report, detectable concentrations of malathion (a pesticide commonly used in agriculture, residential landscaping and mosquito abatement) were found in 28 percent of frozen blueberry samples, 25 percent of fresh strawberry samples and 19 percent of celery samples.

In the Pediatrics study, researchers found that for every tenfold increase in the urinary concentration of pesticide residue, there was a 35 percent increase in the chance that the child would develop ADHD. The effect was seen even in kids who had a very low level of detectable, above-average pesticide residue.

Unlike other studies of pesticidal impact, this one looked at the average exposure to pesticides in the general population of children and not at a specialized group such as children who live on farms, according to lead author Maryse Bouchard of the University of Montreal.

Because certain pesticides leave the body after three to six days, the presence of residue shows that exposure is likely constant, Bouchard said. The study found that children with the kind of metabolites left in the body after malathion exposure were 55 percent more likely to be diagnosed with ADHD. Almost universally, the study found detectable levels: The compounds turned up in the urine of 94 percent of the children. Children may be especially prone to the health risks of pesticides because they’re still growing and may consume more pesticide residue than adults, relative to their body weight.

More research is needed to confirm the findings, says Bouchard. But the take-home message for parents, she says, is to give kids organic produce as much as you can and to wash fresh fruits and vegetables — organic or not — thoroughly.

An unpublished 2008 study out of Emory University found that in children who switched to organically grown fruits and vegetables, urine levels of pesticide compounds dropped to undetectable or close to undetectable levels.

Denver immunologist Dr. Isaac Melamed is studying another effect that may contribute to ADHD: the inflammation caused by all allergies including food, pollen and dust. In his unpublished study, he found that the inflammation caused by an allergic reaction may contribute to ADHD. Therefore, he says, by controlling a child’s exposure to allergens, parents may be able to better control ADHD. Melamed says that although much more study needs to be done on this, in his private practice, he has controlled his patients’ ADHD by limiting allergic triggers.

Remember that all of this research is in the very early stages and needs to be studied more thoroughly before it can be confirmed.

So the parents who conscientiously feed their children fruits and veggies are at most risk for exposing their children to pesticides which may lead to ADHD? And the recommendation is for eating organic vegetables? Or growing your own?
