RESUMO
Control and elimination of filarial pathogens is a central focus of major global health efforts directed at parasitic diseases of developing countries. Accomplishment of these goals would be markedly enhanced by the enhanced destruction of the adult stage of filariae. The identification of new, more quantitative biomarkers that correlate with mortality or chemotherapeutic damage to adult filariae, would greatly facilitate, for example, the development of new macrofilaricides.

A clinically significant endemic focus of onchocerciasis existing in Esmeraldas Province, coastal Ecuador has been under an ivermectin mass drug administration program since 1991. The main transmitting vector in this area is the voracious blackfly, Simulium exiguum. This paper describes the assessments made that support the decision to cease mass treatment.(AU)

A prospective study was carried out in an area of unstable malaria transmission in central Sudan to determine the efficacy and toxicity of quinine in pregnancy. Thirty-three pregnant women with severe Plasmodium falciparum malaria at mean 28.8 weeks gestational age were treated with quinine for 7 days. The mean body temperature on presentation for 3 patients who delivered prematurely was significantly higher than for those who delivered at term [39.2 +/- 0.7 degrees C versus 38.7 +/- 1.3 degrees C]. There were no significant difference between the 2 groups in other clinical or biochemical parameters. There were no clinically detectable congenital malformations and no auditory, visual or other neurological deficits in the babies at birth or 6 months later. Quinine may be safe in the treatment of severe falciparum malaria during pregnancy
