[Comparison of Doppler flowmetry in brachial artery in Mexican postmenopausal women with and without symptoms].

Background: Brachial artery doppler fluxometry permits to evaluate the endothelial function in a non-invasive way.

Objective: To know the effect of vasomotor symptoms in brachial artery flux ultrasonographic parameters in Mexican postmenopausal women.

Material And Methods: A prospective study was done including postmenopausal women divided into two groups: I) without hot-flushes and II) with hot-flushes.

Effect of severity disease on the pharmacokinetics of cefuroxime in children with multiple organ system failure.

The aim of the present study was to investigate if the severity of illness affected the pharmacokinetics of cefuroxime in 11 children diagnosed with multiple organ system failure. The patients were assigned to a severely ill group (group 1), a very severely ill group (group 2), or a control group (group 0). Blood samples were taken and cefuroxime concentrations were measured in plasma by HPLC after the first intravenous infusion of 100 mg of cefuroxime per kg of body weight.
