RESUMO
BACKGROUND: Chloroquine (CQ) and Sulfadoxine-Pyrimethamine (SP) are the predominantly used antimalarials in Zambia and other parts of East Africa, but increasing resistance of P. falciparum is a major concern. METHODS: Seventy consecutive patients with uncomplicated falciparum malaria were enrolled. In 43 patients, no prior CQ use could be demonstrated by history and urianalysis (qualitative test, Dill & Glazko) and these patients were given CQ; the other 27 had taken CQ before and received SP. RESULTS: Combined R-II and R-III CQ-resistance was 58% (60% in under-fives), which is the range previously reported from Zambia. By contrast, SP-resistance (R-II and R-III) was much higher (26%) than previously reported (3% - 17%). The history of prior CQ intake correlated well with the results of the Dill-Glazko test; there was no evidence for prior SP intake to explain these results. CONCLUSION: If our findings of SP resistance are confirmed, other drugs such as quinine, atovaquone/proguanil and artemisinin are required to treat malaria in Zambia.

Complete hydatidiform mole with coexisting live fetus is rare, causing specific difficulties in diagnosis and management. These aspects are illustrated in 2 cases that presented with antepartum haemorrhage. Fetal heart sounds and body parts or uncertainty over the duration of amenorrhoea may delay early diagnosis in the absence of ultrasonography.
