Nodding Syndrome in Uganda: Field Observations, Challenges and Research Agenda

This article summarizes observations made in Northern Uganda and a lecture given at the Nodding Syndrome Workshop in Nagasaki September 2013. The objective of the manuscript is to summarize the current knowledge on nodding syndrome and to provide an agenda for investigations into the epidemiology, pathophysiology, diagnosis and care management of nodding syndrome in Uganda.

Treatment of Parasitic Skin Diseases with DimeticonesA New Family of Compounds with a Purely Physical Mode of Action

Epidermal parasitic skin diseases (EPSD) are common in the tropics and sub-tropics. They are caused by mites, lice and other blood-sucking insects. In resource-poor countries they are associated with considerable morbidity. Hitherto, EPSD are treated with insecticides with a neurotoxic mode of action. The efficacy of this treatment is variable, and the development and spread of resistant mites and lice is alarming.A new concept for treating EPSD is presented which is based on the topical application of dimeticones, silicone oils of low viscosity which rapidly kill insects and mites by a physical mode of action. They creep into the respiratory system and block oxygen supply. The physical mode of action makes the development of resistant parasite strains very unlikely. Due to their safety and efficacy, dimeticones are promising candidates for population-based intervention programmes targeted against EPSD in resource-poor settings.
