"Shake and Shoot" Coca-Cola douches, and Other weird science.

There are several strange items in this article about funny little scientific studies -- actually makes me want to read an issue of the British Medical Journal.

Highlights:
  • "Studies showed that children who consume large amounts of sugar are no more hyperactive than those who don't. But parents who think their kids have eaten sugar, even when they haven't, tend to rate them as being hyperactive.

    The ill-mannered behavior, the authors wrote, was 'all in the parents' minds.'"
  • "Coca-Cola douches for pregnancy prevention were a part of folklore in the 1950s and 1960s, before the contraceptive pill. People thought that the acidity of the soda would kill sperm and that the classic Coke bottle provided a convenient 'shake and shoot' applicator.

    Dr. Deborah Anderson of Boston University School of Medicine had previously reported that Coke can impede the mobility of sperm in a test tube. But further study, she said, shows that sperm get to the cervical canal so quickly that postcoital spritzing is ineffective.

    For it to work, she wrote, the soda would have to be put in the vagina before sex, 'but that would undoubtedly be messy.'"
  • "Drs. Christopher J. Boos and Howard Marshall, cardiologists at University Hospital Birmingham, treated a 25-year-old woman who suffered repeated fainting episodes, particularly when eating a sandwich or drinking a fizzy drink.

    A full medical work-up showed her to be healthy overall, but the team ultimately diagnosed a condition called swallow syncope, which caused her heart to stop beating for as long as three seconds after some types of swallowing -- especially sandwiches, for no clear reason.

    The woman was fitted with a pacemaker and has had no fainting episodes since, Boos and Marshall reported in the Lancet. They suspect that many other patients suffer the problem without being diagnosed."
Ok. So sandwich-fainting is weird. But these doctors think there are many other people who faint when they swallow, and don't notice? Really?
