Doctor invents female condoms with 'teeth' to fight rape



From CNN:

The woman inserts the latex condom like a tampon. Jagged rows of teeth-like hooks line its inside and attach on a man's penis during penetration. Once it lodges, only a doctor can remove it. The doctor inventor says: "It hurts, he cannot pee and walk when it's on. If he tries to remove it, it will clasp even tighter. Yes, my device may be a medieval, but it's for a medieval deed that has been around for decades."

Critics say the female condom is not a long-term solution and makes women vulnerable to more violence from men trapped by the device.

@Skepticscalpel: Great idea. The rapist would likely kill the victim.

@medical__news: I don't know, but old times chastity belts sound more promosing than this invention.

@DrJerath: Wow - interesting.

People who brush their teeth less than twice a day have a 70% increased risk of heart disease

A Scottish national population based survey examined if self reported toothbrushing behaviour is associated with cardiovascular disease and markers of inflammation (C reactive protein) and coagulation (fibrinogen).

Participants were 12,000 men and women, mean age 50. Oral hygiene was assessed from self reported frequency of toothbrushing. There were a total of 555 cardiovascular disease events over an average of 8 years of follow-up, of which 170 were fatal.

Participants who reported poor oral hygiene (never/rarely brushed their teeth) had an increased risk of a cardiovascular disease event (hazard ratio 1.7).

They also had increased concentrations of both C reactive protein and fibrinogen.

Poor oral hygiene is associated with higher levels of risk of cardiovascular disease and low grade inflammation, though the causal nature of the association is yet to be determined.
