[Treatment of pediculosis capitis in children with permethrin 1% shampoo or lotion].
A clinical and entomological trial was carried out in 88 head louse (Pediculus humanus capitis) infested children treated with a single dose of 1% permethrin shampoo or lotion. The sex distribution was 47 males an 41 females with ages ranging between 5 and 14 year olds. In order to assess the efficiency of treatments, search for adult forms, nymphs and eggs (nits) of the parasite was performed in each of the children, before and after treatment (30 minutes, 7 days and 21 days). The entomological evaluations consisted in stereoscopic and microscopic examinations of a mean of 12 hair samples taken from the retroauricular and occipital regions of each of the children, the biological condition of eggs, viable (immature, mature), dead and empty, was recorded. The cure rates--both clinical and entomological--obtained were 91.5% for shampoo and 95.2% for lotion. No adverse reactions with the two formulations used were reported. In conclusion, 1% permethrin shampoo or lotion in an effective and safe treatment for pediculosis capitis.
