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



This difference, however, was no longer recognizable at day 45, and the body lice showed increasing recalcitrance to the insecticide. "This trial clearly demonstrates that the use of insecticide-treated underwear had the consequence of increasing the share of permethrin-resistant body lice in sheltered homeless people," said study leader Samir Benkouiten, of Aix Marseille University, in France. "These findings hint us to recommend avoiding the use of permethrin to upon body-lice infestations, although implementing new strategies is crucial" continue reading.
