The influence of paleoclimatic events on the functioning of an alpine thermal system (France): the contribution of hydrodynamic–thermal modeling

Numerical models of the Aix-les-Bains thermal aquifer (France) were used to investigate the influence of Quaternary paleoclimatic events on the current thermal state of the groundwater. Initial numerical tests were successful in that present-day fluid flows (heads and flow rates) and the resulting velocities were compatible with residence time data. Water flowing through an aquifer cools the rock mass; therefore, the rate of water flow governs the outlets temperature. For the Aix-les-Bains aquifer, applying present-day flow rates to the entire history of the aquifer leads to much more substantial cooling of the rock mass than is indicated by the outlets temperature (i.e. present-day flow rates are 10 times too high). This suggests that the aquifer may have gone through alternating functioning phases, during which the rock mass cooled, and blocked phases, during which the aquifer reheated. Other results indicate that the main parameters affecting thermal behavior during a functioning phase are the total inflow volume, rather than individual inflow rates, and the initial heat field. As phenomena linked to glaciation can lead to the blocking of infiltration zones and aquifer outlets, the findings suggest that the hypothesis of intermittent aquifer functioning related to glaciations is compatible with the current thermal field

Thermal varicose treatment under hypnosis

AbstractHypnosis has undergone great developments throughout the history of mankind. Medical hypnosis is a much more recent medical discipline that has been slow to be recognized as such. Today it has a well-defined place and there is no longer any doubt as to its effectiveness, as evidenced by its establishment in our services and the number of publications about it. The management of varicose veins of the lower limbs by thermal ablation is a very good indication for hypnosis, then called hypnoanalgesia. Practitioners who are well trained and experienced in hypnosis can use it during these procedures and bring undeniable comfort to their patients. A protocol is presented here adapted to the practice of this ablation procedure while meticulously following the principles of Ericksonian hypnosis.</jats:p

Optimisation du temps d'hospitalisation des patients présentant une thrombose veineuse profonde des membres inférieurs

Quels sont les paramètres intervenant dans l'optimisation de la prise en charge hospitalière des patients présentant une thrombose veineuse profonde des membres inférieurs ? Afin de répondre à cette question, une étude épidémiologique descriptive de cohorte a été réalisée durant une période de 7 mois au sein des services de Médecine et de Chirurgie du Centre Hospitalier Universitaire de Nantes. Deux axes ont été abordés : la prise en charge pré hospitalière et la prise en charge hospitalière. Une enquête a été réalisée auprès des médecins généralistes. L analyse des comptes rendus d hospitalisation est venue compléter l étude. Ce qui ressort est la place dominante de la prise en charge ambulatoire des thromboses veineuses profondes d une part et l importance des critères médico-sociaux dans la justification de leur prise en charge hospitalière d autre part. Cette étude montre qu environ un tiers des comptes rendus hospitaliers ne donnent pas au médecin traitant de conduite à tenir précise. L amélioration de la prise en charge des patients présentant une thrombose veineuse profonde permettra de favoriser les prises en charge ambulatoires chaque fois que cela est possible et de raccourcir la durée d hospitalisation tout en favorisant l interaction Ville-Hôpital.NANTES-BU Médecine pharmacie (441092101) / SudocPARIS-BIUM (751062103) / SudocSudocFranceF
