On établit pour les centralisateurs dans une PD(3)-paire des résultats analogues à ceux connus pour les centralisateurs dans un groupe fondamental de variété de dimension 3. Comme dans le cas des groupes fondamentaux de variétés de dimension 3, la preuve de ces résultats repose sur une décomposition JSJ pour les PD(3)-paires obtenue à l'aide de la théorie des voisinages algébriques réguliers de Scott et Swarup.

A cluster of three measles cases occurred at the Gendarmerie of Rambouillet in March 2011. A survey conducted among 170 subjects highlighted the difficulty of gathering information about patients (previous infection or vaccination) and of planning the vaccination of non-immune contacts. The study also found that the proportion of immunized patients increased from 25% to 43% after one vaccination. The disappointing results highlight the public health role of family practitioners involving in informing and vaccinating patients before measles epidemics occur.

Nationale (GIGN) is a police special force unit from the military. Its main missions are counter-terrorism, fight organized crime, and also protection and security of vital keypoints of the nation and state, in France and overseas as well. The GIGN is trained to work under chemical, biological, radiological, or nuclear (CBRN) conditions. The aim of this study is to improve CBRN medical support. Methods: An in-depth literature analysis was conducted to the great expertise of the GIGN medical unit and of the French Service de Sante des Armees. Results: Before a mission, the physicians of the military are key actors to train soldiers to face CBRN conditions. They define medical countermeasures including personal protective equipment (PPE) and antidote kits including Ineurope® auto-injecting syringes that contain atropine, pralidoxim, and diazepam. During the mission, the medical units, including the GIGN, are able to move and work in contaminated areas. They can initiate the medical care of classic soldier wounds and CBRN contaminated wounds as well. The impact of the pharmaceutical and antidote kits and specific training are of great importance to accomplish the medical mission while wearing PPE. They can also strengthen CBRN decontamination modules of the Gendarmerie. Conclusions: The CBRN risk must be considered for Special Force medical unit: training, constantly adapting the protective equipment and specific therapeutics to the risk is a major challenge.
