Randomized Controlled Trial Clinical Trial
Readers' evaluation of effect of peer review and editing on quality of articles in the Nederlands Tijdschrift voor Geneeskunde.
Academic biomedical journals use peer review and editing to help to select and improve the quality of articles. We have investigated whether articles accepted by the Nederlands Tijdschrift voor Geneeskunde, the Dutch Journal of Medicine, were improved after peer review and editing (post-acceptance scientific and copy editing). ⋯ Evaluations by readers of the Ned Tijdschr Geneeskd indicated significant improvement of published articles after both peer review and editing. We think that peer review and editing are worthwhile tasks. We also think that possible biases would have had a negligible effect on our results (including the fact that we selected the first 25 evaluators who responded, that some evaluators may have read the published version, and that one questionnaire may have looked more scientific than the other, more editorial one).

Randomized Controlled Trial Clinical Trial
Randomised trial of efficacy of benznidazole in treatment of early Trypanosoma cruzi infection.
Benznidazole, a nitroimidazole derivative, has been recommended for the treatment of acute and congenital Trypanosoma cruzi infection (Chagas' disease). We have examined the safety and efficacy of this drug in the treatment of the early chronic phase of T cruzi infection. ⋯ The trial showed that a 60-day course of benznidazole treatment of early chronic T cruzi infection was safe and 55.8% effective in producing negative seroconversion of specific antibodies. The results are very encouraging and justify the recommendation of treatment for seropositive children as public health policy.
