[Followup of pregnant women in the context of malaria: two case reports]. / Suivi de la grossesse dans le cadre du Paludisme: à propos de deux observations.

Whether or not a pregnant women should travel to regions where malaria is highly endemic will always be open to question as no prophlaxis can guarantee complete protection in every case. No chemoprophylaxis is 100% effective or entirely without side-effects, particularly for pregnant women whose immune status provides a favourable environment for the emergence of this parasitosis. The advice given will depend on the country and the region, a possible resistance of the parasite to treatment, the season, the length and circumstances of the stay and individual factors. The choice of treatment is very limited as many therapies are contra-indicated in pregnancy; in addition it is extremely important to give a sufficiently clear explanation concerning precautions and prophylaxis as well as of how a possible bout of malaria should be treated, particularly in case of extended stay.

Experimental verification of semiclassical and RPA calculations of the static conductivity in moderately nonideal plasmas.

We present an experimental verification of the semiclassical theory for static conductivity calculations in the case of moderately nonideal plasmas. Such plasmas are produced in linear flashlamps filled with pure helium and are characterized by on axis electron densities in the range 2x10(17)-1.7x10(18) cm(-3) and temperatures (2-3)x10(4) K. Precise measurements of the discharge electrical parameters have been carried out and in each case the impedance of the plasma was compared with the calculated value using the semiclassical theory, which is a simpler approximation than the quantum-mechanical theory based on the random-phase approximation.
