A New Way To Fight Head Lice

A New Way To Fight Head Lice.
Insecticide-treated underwear won't wipe out lice infestations in dispossessed shelters, according to a additional study. The design initially showed some success, but the lice soon developed resistance to the chemical, the researchers said. Body lice can limits through direct contact and shared clothing and bedding, and the problem is worsened by overcrowded conditions.

The study, which was published online Dec 4? 2013 in the review JAMA Dermatology, examined the force of giving homeless people underwear treated with the insecticide permethrin. Forty participants were given green underwear treated with the insecticide and 33 others received untreated underwear. They were checked 14 and 45 days later. On hour 14, the researchers found that 11 of the 40 commonalty given treated underwear were free of body lice, compared with three of the 33 who received untreated underwear.

This difference, however, was no longer perceivable at day 45, and the body lice showed increasing defences to the insecticide. "This trial clearly demonstrates that the use of insecticide-treated underwear had the consequence of increasing the portion of permethrin-resistant body lice in sheltered homeless people," said study leader Samir Benkouiten, of Aix Marseille University, in France. "These findings bring on us to recommend avoiding the use of permethrin to boon body-lice infestations, although implementing new strategies is crucial" pro extender deluxe.
