Cutaneous biopsy specimens obtained from bone marrow transplant (BMT) patients, most with graft-vs-host disease (GVHD), were analyzed for infiltration by helper, cytotoxic, and suppressor T lymphocytes and natural killer cells. Lesional skin from patients with early mild GVHD and drug reactions showed a CD4/CD8 ratio of 5.0 or more, but later biopsy specimens from patients with acute GVHD and the majority of sections from those with chronic GVHD showed a CD4/CD8 ratio of 0.8 to 3.0 due to increased numbers of presumably cytotoxic cells. Significant numbers of suppressor (CD11 +/- CD16b-) cells were found in only one patient with severe chronic GVHD. Natural killer cells were not found. Preliminary examination of lesional skin from seven autologous BMT patients showed a similar trend of decreased CD4/CD8 ratios in the three patients with a syndrome that resembled GVHD. Analysis of CD4/CD8 ratios in serial biopsy specimens from patients with GVHD may allow more accurate monitoring of the progression of cutaneous GVHD and may help to elucidate the mechanism of development of the GVHD-like reaction in autologous BMT patients.
Reorganization of the office-based emergency care system is currently on the political agenda in Germany. Analysing the present situation, the present study makes an empirical comparison between usage of the office-based emergency service and of the competing hospital outpatient departments in different localities, also examining the possible reasons for the differences.Family doctor density was found to have a negative influence on the number of cases in hospital outpatient departments and a positive influence on the number of cases dealt with by the emergency service of the office-based physicians. Further, the number of hospitals in a county correlates positively with the cases in hospital outpatient departments.
Cette journée d'étude, organisée dans le cadre du laboratoire Center for Research on the English-speaking World (CREW -EA 4399) par Annick Cizel, James Cohen et Jean-Baptiste Velut, a exploré des champs d'études très divers. De l'histoire diplomatique transatlantique aux dynamiques de pouvoir intérieures et extérieures à la politique environnementale, en passant par l'économie, la diplomatie commerciale ou encore la politique institutionnelle, ce colloque a offert un large panorama des actions du président américain Donald Trump en matière de politique étrangère et de ses conséquences nationales, internationales et transnationales. Nous ferons ici un compte rendu des différentes interventions en lien avec la politique étrangère du président américain, tous champs disciplinaires confondus. Cette journée a permis de rendre compte de différentes approches possibles dans la définition du leadership des États-Unis sous Donald Trump, du multilatéralisme et de la séparation des pouvoirs, mais aussi des relations internationales au vu des défis actuels du monde interconnecté dans lequel nous vivons. « Trump et le grand échiquier mondial » 2 Cette journée a permis d'organiser trois ateliers thématiques. Le premier de la matinée, durant lequel sont intervenus Alexandra de Hoop Scheffer, Martin Quencez et Annick Cizel s'articulait autour du concept « Trump et le grand échiquier mondial ». La communication d'Alexandra de Hoop Scheffer (GMFUS / Sciences Po Paris) visait à « Journée d'étude « Donald Trump et la politique étrangère des Etats-Unis: vers...
