We randomized the households of the study participants into an intervention and a control group and prospectively calculate...
BACKGROUND There are two components to the clinical efficacy of pediculicides: (i) efficacy against the crawling-stages (lousicidal efficacy); and (ii) efficacy against the eggs (ovicidal efficacy). Lousicidal efficacy and ovicidal efficacy are confounded in clinical trials. Here we report on a trial that was specially designed to rank the clinical ovicidal efficacy of pediculicides. Eggs were ...

The relationships between and within these groups of insects are difficult to resolve because only few informative molecular and morphological characters are available. Her...
