INTRODUCTION: High-flow nasal cannula (HFNC) can deliver heated and humidified gas (up to 100% oxygen) at a maximum flow of 60 L/min via nasal prongs or cannula. The aim of this study was to assess the short-term physiologic effects of HFNC. Inspiratory muscle effort, gas exchange, dyspnea score, and comfort were evaluated. METHODS: Twelve subjects admitted to the ICU for acute hypoxemic respiratory failure were prospectively included.

Plasmodium falciparum malaria is usually transmitted by mosquitoes. We report 2 cases in France transmitted by other modes: occupational blood exposure and blood transfusion. Even where malaria is not endemic, it should be considered as a cause of unexplained acute fever.

We propose a practical algorithm to avoid unnecessary PLT transfusion before CVC insertion for rapid PE in the initial management of TTP patients. We recommend no prophylactic PLT transfusion but CVC insertion in a compressible vein under ultrasound guidance by an experienced team or quick PE started on two peripheral veins if possible. PLTs should only be transfused in case of severe bleeding in association with plasma infusion and CVC insertion for immediate PE.
