Background: Increasing in the prevalence of pediculosis among school students and upward trend of pesticide marketing with evidence of resistance to them, indicate the possibility of lice resistance. Objective: To compare 3 drug formulations including: Lindan shampoo 1%, permethrin shampoo 1% and Copex powder 0.5% in the treatment of head lice infestation. Patients and Methods: Ninety students with a confirmed diagnosis of pediculosis were selected from rural schools and randomly treated in 3 equal groups with the mentioned medications. The results were evaluated after 24 hours, 1, 2 and 6 weeks. Results: The rate of healing was 83.3%, 100%, 100% after 24 hours, 70%, 93.3%, 90% after 1 week, 63.3%, 90%, 76.7% after 2 weeks and 40%, 83.3%, 66.7% after 6 weeks in patients treated with Lindan, permethrin, and Copex powder, respectively (P<0.05, chi-square test). Conclusion: Considering the numerous side effects of current treatment options like Lindan, alternative treatments must be trailed especially in fall and winter because of high rate of infestation during these seasons to interfere with resistancy.

Background: Some researchers claim that permethrin-impregnated clothes are effective in the prevention of cutaneous leishmaniasis. Objectives: To determine the effectiveness of permethrin-impregnated clothes in the prevention of cutaneous leishmaniasis. Patients and Methods: 272 soldiers were randomized in two groups. In one group permethrin-impregnated clothes and in the other group, control clothes were used. In each group the clothes were worn during days and nights for three months and the soldiers were followed for additional 6 months. Results: 9 (6.5%) of 138 soldiers wearing control clothes and 6 (4.4%) of 134 soldiers wearing permethrin-impregnated clothes acquired cutaneous leishmaniasis. The difference between two groups was not statistically significant. Conclusion: Permethrin-impregnated clothes are not effective in the prevention of cutaneous leishmaniasis.
