Molecular surveillance of putative drug resistance markers of antifolate and artemisinin among imported in Qatar.

Malaria remains a significant public health challenge and is of global importance. Imported malaria is a growing problem in non-endemic areas throughout the world and also in Qatar due to a massive influx of migrants from endemic countries. Antimalarial drug resistance is an important deterrent in our fight against malaria today.

Distribution of Mutations Associated with Antifolate and Chloroquine Resistance among Imported in the State of Qatar.

is the most prevalent parasite worldwide, escalating by spread of drug resistance. Currently, in Qatar, chloroquine (CQ) plus primaquine are recommended for the treatment of malaria. The present study examined the prevalence of mutations in dihydrofolate reductase (), dihydropteroate synthase () genes and CQ resistance transporter () genes, associated with sulphadoxine-pyrimethamine (SP) and chloroquine resistance, among imported cases in Qatar.

Computed tomography abnormalities and epidemiology of adult patients presenting with first seizure to the emergency department in Qatar.

Objectives: There is little information available from the Middle Eastern region on adult patients presenting with first seizure. The objectives of this study were to describe epidemiological characteristics of patients presenting to the emergency department (ED) in Doha, Qatar, with first seizure and to determine the incidence of computed tomographic (CT) scan abnormalities.

Methods: A retrospective cohort study was conducted on all adult patients with first seizure presenting to Hamad General Hospital ED over a 1-year period (June 2012 through May 2013).
