RESUMO
The agar plate method is a new and highly sensitive technique for diagnosis strongyloidiasis. We detected strongyloidiasis from 331 villagers in Khon Kaen province by using this technique. There were 82 cases (24.77%) positive for Strongyloides stercoralis. They were administered albendazole 400 mg orally once a day for 3 consecutive days. Only 51 cases submitted stools for re - examination two weeks after treatment. There were 38 cases cured (74.51%) This study showed that strongyloidiasis is still a high cause of infection in Khon Kaen and the dosage of 400 mg orally once a day for 3 consecutive days of albendazole showed effective treatment.
RESUMO
This study was conducted to estimate the prevalence of head lice in primary school children and to compare the efficacy of 25% benzyl benzoate versus 1% gamma benzene hexachloride (1% lindane). The prevalence rate was 31.58% (66 out of 209). Eighteen out of 24 (75%) were cured when they were treated by 25% benzyl benzoate. Twenty-six out of thirty (86.67%) were cured when they were treated by 1% lindane. There was no statistical significant difference between the two pesticides for treatment head lice (P\>0.05, Chi-square test). The doctors can choose one of the two pesticides for treatment head lice.
RESUMO
This study was conducted to estimate the prevalence of head lice in primary school children in Chiangyuen district and to compare the efficacy of a 3 hour versus a 12 hour application of 1% gamma benzene hexachloride (1% lindane). Two schools were selected at random. Children who were infested with head lice received a 12 hour application of 1% lindane in the first school, while those in the second group received a 3 hour application. While none of the boys examined were infested, there were 39 (41.1%) and 41 (44.1%) female children with pediculosis capitis in two schools, respectively. Thirty-seven out of 38 and 23 out of 41 infections were cured when the drug was applied for 12 and 3 hours, respectively. This study showed that there is still a high prevalence of pediculosis in female school children and that 3 hour applications of lindane are less effective (P \< 0.05) in curing head lice infestations than 12 hour applications.
