Une mauvaise hygiène des mains peut représenter une perte économique importante pour les industries alimentaires ou les industries pharmaceutiques et constitue un gros problème de santé publique dans les établissements de soins. En effet, le risque de transmission manuportée de pathogènes d'un patient à l'autre via le personnel soignant est un problème récurrent dans tous les hôpitaux. C'est pourquoi, une hygiène irréprochable des mains du personnel soignant est une composante fondamentale de lutte contre les infections nosocomiales. En comparaison avec les autres techniques de séchage des mains, l'utilisation d'une serviette en papier à usage unique semble être la méthode la plus efficace pour éliminer les bactéries. En effet, les autres méthodes de séchage, utilisant des appareils à air chaud ou froid, peuvent générer un air contaminé ou remettre en suspension les germes restés sur la peau, facilitant ainsi leur dispersion et leur inhalation. C'est pourquoi, l'OMS a émis des recommandations déconseillant les sèche-mains électriques en milieu hospitalier au profit des serviettes en papiers. Cependant, ces serviettes à usage unique ne sont pas stériles et peuvent elles-mêmes déposer des germes, généralement non pathogènes, sur les mains lors du séchage. Le but du premier article analysé est d'évaluer le niveau de contamination de ces serviettes, ainsi que la possibilité de dépôt de ces bactéries présentes sur les serviettes, sur les mains. À côté du risque de propagation de pathogènes par contact direct, la contamination microbiologique par voie aérienne via les aérosols existe aussi. Pour éviter d'être contaminé par des personnes excrétrices de micro-organismes transmissibles par aérosols (tuberculose, grippe, grippe aviaire SRAS...), il faut porter des protections respiratoires de type FFP2 (1) (norme européenne équivalente à la norme anglosaxonne N95). Ces protections respiratoires ou masques filtrants (en formes de bec de canard) peuvent être portées théoriquement pendant 4 heures. Le but de l'étude du second article est d'évaluer le risque de remise en suspension dans l'air de particules virales présentes sur la face extérieure d'un masque de protection respiratoire lors de simulation d'épisodes de toux provenant du porteur de cette protection.

BACKGROUND/AIMS: The present report examines a new pig model for progressive induction of high-grade stenosis, for the study of chronic myocardial ischemia and the dynamics of collateral vessel growth. METHODS: Thirty-nine Landrace pigs were instrumented with a novel experimental stent (GVD stent) in the left anterior descending coronary artery. Eight animals underwent transthoracic echocardiography at rest and under low-dose dobutamine. Seven animals were examined by nuclear PET and SPECT analysis. Epi-, mid- and endocardial fibrosis and the numbers of arterial vessels were examined by histology. RESULTS: Functional analysis showed a significant decrease in global left ventricular ejection fraction (24.5 +/- 1.6%) 3 weeks after implantation. There was a trend to increased left ventricular ejection fraction after low-dose dobutamine stress (36.0 +/- 6.6%) and a significant improvement of the impaired regional anterior wall motion. PET and SPECT imaging documented chronic hibernation. Myocardial fibrosis increased significantly in the ischemic area with a gradient from epi- to endocardial. The number of arterial vessels in the ischemic area increased and coronary angiography showed abundant collateral vessels of Rentrop class 1. CONCLUSION: The presented experimental model mimics the clinical situation of chronic myocardial ischemia secondary to 1-vessel coronary disease.
