Suite à un accident exposant à du sang (piqûre; coupure), provenant d'un patient infecté, le risque d'infection par VIH est d'environ 0,3% et par le virus de l'hépatite C (VHC) d'environ 0,5%. Chez les personnes vaccinées avec une réponse immunitaire adéquate (titre d'anticorps HBs >100 mUI/ml), aucune infection professionnelle par hépatite B n'a été reconnue en Suisse. La plupart des infections par VIH et VHB peuvent être prévenues par un traitement d'urgence et une prophylaxie postexpositionnelle (PEP). Il n'y a actuellement aucune prophylaxie postexpositionnelle pour le VHC. En cas de transmission de VHC, un traitement rapide par peginterféron et ribavirine est à envisager. Chaque hôpital et cabinet médical doivent mettre sur pied un système pour assurer une prise en charge optimale et en urgence des blessures par piqûres ou coupures. Lors de blessures accidentelles avec du sang de patients séropositifs pour le VIH et dans des situations complexes, il est recommandé de consulter un médecin du personnel ou un infectiologue expérimenté. The risk of infection after an occupational needle stick injury with blood from an infected source patient is approximately 0.3% for HIV and 0.5% for hepatitis C virus (HCV). In Switzerland no cases of occupational HBV infection have been recorded in fully vaccinated persons with a documented adequate vaccine response (HBsantibody titer >100 mIU/mL). Most occupational HIV und HBV infections can be prevented by appropriate emergency measures and post-exposure prophylaxis (PEP). No HCV-PEP is currently available. Early therapy with peginterferon and ribavirin should be considered in cases of occupational HCV seroconversion. Every hospital and office practice should establish a system for 24 h/24 h emergency management of occupational needle stick injuries. In the setting of an HIV-seropositive source patient and in complex situations, early consultation with a specialist in occupational medicine or infectious diseases should be considered.

Le présent rapport se propose d'identifier la manière dont la prévention des pathologies professionnelles retenues dans le cadre de l'étude (pathologies dues à des substances chimiques ou facteurs physiques: amiante, bruit, ciment, huiles de coupe, isocyanates, poussières de bois, résines époxy) ainsi que des cancers professionnels est abordée dans les pays sélectionnés et de décrire des campagnes ayant fait la preuve de leur efficacité et perçues comme susceptibles d'être reprises en Suisse.

Gaysurvey est une enquête menée périodiquement en Suisse parmi les hommes qui ont des relations sexuelles avec des hommes (HSH). Elle s'inscrit dans le dispositif de surveillance du VIH, établi par l'Office fédéral de la santé publique, en tant qu'instrument de suivi des comportements face au VIH/sida dans ce groupe-cible. Elle a déjà été réalisée à huit reprises. [Auteurs, p. 5] [Table des matières] 1. Résumé. 2. Zusammenfassung. 3. Introduction. 4. Méthodologie. 5.

The Guelb Moghrein Fe oxide-Cu-Au-Co deposit is located at the western boundary of the West African craton in NW Mauritania. The wall rocks to the mineralization represent a meta-volcanosedimentary succession typical of Archaean greenstone belts. Two types of meta-volcanic rocks are distinguished: (1) volcanoclastic rocks of rhyodacite-dacite composition (Sainte Barbe volcanic unit), which form the stratigraphic base; (2) tholeiitic andesites-basalts (Akjoujt meta-basalt unit). The trace element signature of both types is characteristic of a volcanic arc setting. A small meta-pelitic division belongs to the Sainte Barbe volcanic unit. A meta-carbonate body, which contains the mineralization, forms a tectonic lens in the Akjoujt meta-basalt unit. It can be defined by the high X(mg) (=36) of Fe-Mg carbonate, the REE pattern and the delta(13)C values of -18 to -17 parts per thousand as a marine precipitate similar to Archaean banded iron formation (BIF). Additionally, small slices of Fe-Mg clinoamphibole-chlorite schist in the meta-carbonate show characteristics of marine shale. This assemblage, therefore, does not represent an alteration product, but represents an iron formation unit deposited on a continental shelf, which probably belongs to the Lembeitih Formation. The hydrothermal mineralization at 2492 Ma was contemporaneous with regional D(2) thrusting of the Sainte Barbe volcanic unit and imbrications of the meta-carbonate in the upper greenschist facies. This resulted in the formation of an ore breccia in the meta-carbonate, which is enriched in Fe, Ni, Co, Cu, Bi, Mo, As and Au. Massive sulphide ore breccia contains up to 20 wt% Cu. The ore fluid was aqueous-carbonic in nature and either changed its composition from a Mg-rich oxidizing to an Fe-rich reducing fluid or the two fluid types mixed at the trap site. All lithologies at Guelb Moghrein were deformed by D(3) thrusting to the east in the lower greenschist facies. The mobility of REE in the retrogressed rocks explains the formation of a second generation of hydrothermal monazite, which was dated at c. 1742 Ma. Archaean rocks of the West African craton extend to the west to Guelb Moghrein. The active continental margin was deformed and mineralized in the Late Archaean-Early Proterozoic and again reactivated in the Mid-Proterozoic and Westphalian, showing that the western boundary of the craton was reactivated several times.

BACKGROUND: In the United States, the Agency for Healthcare Research and Quality (AHRQ) has developed 20 Patient Safety Indicators (PSIs) to measure the occurrence of hospital adverse events from medico-administrative data coded according to the ninth revision of the international classification of disease (ICD-9-CM). The adaptation of these PSIs to the WHO version of ICD-10 was carried out by an international consortium. METHODS: Two independent teams transcoded ICD-9-CM diagnosis codes proposed by the AHRQ into ICD-10-WHO. Using a Delphi process, experts from six countries evaluated each code independently, stating whether it was "included", "excluded" or "uncertain". During a two-day meeting, the experts then discussed the codes that had not obtained a consensus, and the additional codes proposed. RESULTS: Fifteen PSIs were adapted. Among the 2569 proposed diagnosis codes, 1775 were unanimously adopted straightaway. The 794 remaining codes and 2541 additional codes were discussed. Three documents were prepared: (1) a list of ICD-10-WHO codes for the 15 adapted PSIs; (2) recommendations to the AHRQ for the improvement of the nosological frame and the coding of PSI with ICD-9-CM; (3) recommendations to the WHO to improve ICD-10. CONCLUSIONS: This work allows international comparisons of PSIs among the countries using ICD-10. Nevertheless, these PSIs must still be evaluated further before being broadly used.
