    La plongĂ©e sous-marine est une activitĂ© de loisir en plein essor. La respiration de mĂ©langes gazeux sous pression expose cependant son pratiquant au risque d'accident de dĂ©compression. Ce risque, faible, est estimĂ© entre 1 et 5 pour 10,000 plongĂ©es mais les consĂ©quences potentiellement graves en font une pathologie redoutable. La recompression en urgence au caisson hyperbare est le seul traitement thĂ©rapeutique efficace contre ces accidents. Les protocoles de recompression utilisĂ©s en majoritĂ© sont issus des travaux de l'US Navy et prĂ©conisent l'utilisation de tables en oxygĂšne pur. D'autres tables associant un gaz inerte (azote ou hĂ©lium) peuvent ĂȘtre utilisĂ©es notamment lorsque les tables Ă  l'oxygĂšne ne permettent pas d'obtenir un rĂ©sultat satisfaisant. Le COHB de Lyon utilise des tables profondes hĂ©liox depuis 15 ans avec des rĂ©sultats intĂ©ressants. Le but de cette Ă©tude est d'Ă©valuer ces tables en reprenant tous les cas traitĂ©s depuis 5 ans. Les patients ont Ă©tĂ© recontactĂ©s afin de rĂ©cupĂ©rer le maximum de donnĂ©es et d'avoir une vision objective de ce traitement. Les rĂ©sultats montrent non seulement une efficacitĂ© sur le plan clinique remarquable, mais aussi une sĂ»retĂ© d'utilisation maximale pour les patients. Nous ne voyons donc pas de limitations Ă  l'utilisation de ce type de table dans le traitement des accidents de dĂ©compression de type II. Il serait intĂ©ressant de pouvoir Ă©largir leur usage Ă  d'autres centres hyperbares.Scuba diving is a ever growing leisure activity. However breathing gases under pressure exposes divers to the risk of decompression sickness (DCS). This risk is low and estimated between 1 to 5 for 10,000 dives but its consequences potentially harmful make the gravity of this disease. The emergency recompression in an hyperbaric chamber is the only therapeutic efficient mean against those accidents. The procedures of decompression used in majority are mainly based on US Navy works and recommend the use of 100 percent oxygen tables. Others tables associating an inert gas (nitrogen or helium) can be used in particular when the oxygen tables don't give a satisfactory result. The COHB of Lyon uses deep heliox tables for 15 years with interesting results. The goal of this study is to evaluate these tables. We have contacted all the patients treated with such tables during the last five years to gather a maximum of data. Results show a remarkable efficiency on the decompression disease but also a maximal security for patients. We don't see any limit to the extensive use of this kind of therapeutic tables in the treatment of DCS type II. It should be interesting to enlarge theirGRENOBLE1-BU MĂ©decine pharm.

    International audienceBACKGROUND:Prostate cancer is the leading type of cancer among men in more developed countries. Incidence trends and survival rates could differ by age groups considering potential differences in the frequency of PSA testing, types of cancers and medical management. Our objective was to compare incidence trends and survival rates of prostate cancer between men aged ≄75 and 60-74 years.METHOD:We analyzed data from a population-based cancer registry in IsĂšre, France. All men aged ≄60 years diagnosed with an incident prostate cancer during the 1991-2013 period were included. Incidence and mortality rates were computed as well as net survival rates.RESULTS:In 2013, observed incidence rates were 557.6 and 568.7 per 100,000 for men aged 60-74 and ≄75, respectively, with high grades cancers more frequent among elderly men. The incidence and mortality trends among men aged ≄75 included a period of stability followed by a decreasing trend from 2003, whereas a peak of incidence was observed in 2005 for men aged 60-74. For both age groups, net survival rates increased with period of diagnosis and 8-year net survival remained higher than 70% for cases diagnosed in the 2000-2004 period. Lower survival rate of 51% (95%CI: 42%; 60%) was observed for high grades cancers diagnosed among men aged 75-84 in 2000-2004.CONCLUSION:The epidemiology of prostate cancers among men aged ≄75 include a decrease of incidence and mortality rates from 2003, an important proportion of high grade cancers and a relatively good prognosis except for high grade cancers
