Usefulness of simulated cases for assessing pandemic influenza preparedness plans.

To evaluate compliance with preparedness plans, actors simulating avian influenza attended various hospital emergency departments and public health centres during the last quarter of 2007. Most centres (89%) did not respond correctly. The useful information obtained was sent to the medical and administrative staff who were responsible for the preparedness plans.

[Dendritic cells in sepsis: an approach to post-infectious immunosuppression].

Dendritic cells (DCs) play a decisive role in the immune system, especially in the initial events that determine coordination between the innate and adaptive response. Moreover, they are antigen-presenting cells which, through contact with T cells, determine the type of immune responses towards inflammatory or anti-inflammatory. Currently, the hypothesis that attributes importance to the development of a post-infectious immunosuppression in the prognosis of the septic patient is growing stronger.
