Burden and Experiences of Head Lice Infestation Among Children in Western Australia
Journal of Parasitology Research, Volume 2026, Issue 1, 2026.Background Head lice is an ectoparasitic skin infection commonly seen in primary school–aged children. In remote Australia, where rates of other skin infections and downstream sequelae are endemic, the rate of head lice infestation is unknown. Methods This multimethod observational study is aimed at describing the burden of head lice for remote ...

The metabolic fate of pyrethrin I, pyrethrin II, and allethrin.
Bulletin of the World Health Organization, 1971 By the administration of radioactively labelled compounds, the metabolic products of pyrethrin I, pyrethrin II, and allethrin in the rat have been identified. This paper describes the structures of the metabolites.

Pesticide Residues in Foods in Ghana: A Systematic Review
Health Science Reports, Volume 8, Issue 12, December 2025.ABSTRACT Background and Aim Pesticide use has surged globally to enhance agricultural productivity. However, this reliance, particularly in developing countries like Ghana, has raised concerns about pesticide residues in foods and their potential health impacts on the population. Exposure to pesticide residueshas been linked to acute poisoning, cancers,
