title: Increasing pesticide-resistant ectoparasitic infections may increase pesticide poisoning risks in children.
abstract: Head louse and scabies mite infestations are common among pre-school and school-age children, and topical pesticides are frequently prescribed to treat such conditions. Ectoparasite resistance to the safest and most commonly prescribed pyrethrin/pyrethroid pesticides for ectoparasitic infections has, however, been increasing since the 1980s. The increasing resistance of these arthropods to the safest pesticides may lead to greater use of more toxic, alternative pesticides to control infestations and to prevent institutional outbreaks. MEDLINE and Cochrane searches, 1966-2008, were conducted to assess the impact of increasing pesticide resistance on prescribing practices for ectoparasitic infections and to describe the evolving global epidemiology of pediatric poisonings by more toxic pediculicides and miticides, including carbamates, organochlorines, and organophosphates. Pharmacists, physicians, and poison control personnel should be fully informed about increasing pesticide resistance among the most commonly encountered ectoparasites of children and the institutionalized and be prepared to prevent and to treat accidental home and institutional pesticide poisonings with more toxic pesticides.
