It is also often indicated in case of known epilepsy.& para;& para;The main differential diagnosis of convulsive SE is psychogenic non-epileptic stotus.& para;& para;In non-convulsive status epilepticus, the use of anesthetic agents should be considered only rarely, as the risks of such on approach are often greater than the expected benefits
Church of Saint Stephen, Beauvais: Overall view
No full textLouis Graves, Beauvaisien archaeologist, proposed to the Committee on Historical Monuments to close the church because of structural decay. It is classified an historic monument April 25, 1846. In 1892 money is finally released for repairs.\u000a\u000aThe church of Saint-\u00C9tienne is a Romanesque-Gothic building (rebuilt after 1180-1220). It has a Romanesque nave of the twelfth and thirteenth centuries and a Gothic choir of the sixteenth century. The north transept has exterior sculpture around one of the rose windows that is a 'wheel of life' or 'fortune's wheel'. The church is noted for its stained glass by Engrand Le Prince and Nicolas Le Prince, whose masterpieces include the Tree of Jesse window (1524)

No full textLa célébration des anciens peintres verriers par Pierre Le Vieil, vitrier du Siècle des lumières
No full textL’art de la peinture sur verre et de la vitrerie de Pierre Le Vieil (1708-1772), traité à caractère historique et technique publié en 1774, est une des bases de l’historiographie du vitrail. L’auteur, un vitrier parisien fort érudit, consacre une part de son ouvrage aux peintres verriers du passé, hommage que nul n’avait jusque-là songé à leur rendre. Sa méthode, clairement énoncée, repose sur la compilation de documents inédits et de publications (Sauval, Félibien, etc.) plutôt que sur sa connaissance du terrain. Certains des artistes retenus, comme Engrand Le Prince ou Valentin Bousch, bénéficient d’informations fondatrices. Robert Pinaigrier, en revanche, est une personnalité fictive, qui résulte de l’amalgame de mentions concernant pour la plupart Nicolas Pinaigrier, un peintre verrier majeur de la fin du XVIe siècle. Cette protohistoire des peintres verriers mêle en outre aux professionnels de la peinture sur verre des peintres comme Jean Cousin, qui ont joué dans le domaine un rôle ponctuel en tant que cartonniers.Gatouillat Françoise.

Cometary Dust
No full textInternational audienceThis review presents our understanding of cometary dust at the end of 2017. For decades, insight about the dust ejected by nuclei of comets had stemmed from remote observations from Earth or Earth’s orbit, and from flybys, including the samples of dust returned to Earth for laboratory studies by the Stardust return capsule. The long-duration Rosetta mission has recently provided a huge and unique amount of data, obtained using numerous instruments, including innovative dust instruments, over a wide range of distances from the Sun and from the nucleus. The diverse approaches available to study dust in comets, together with the related theoretical and experimental studies, provide evidence of the composition and physical properties of dust particles, e.g., the presence of a large fraction of carbon in macromolecules, and of aggregates on a wide range of scales. The results have opened vivid discussions on the variety of dust-release processes and on the diversity of dust properties in comets, as well as on the formation of cometary dust, and on its presence in the near-Earth interplanetary medium. These discussions stress the significance of future explorations as a way to decipher the formation and evolution of our Solar System
Case report: Varicella-zoster virus encephalitis a new type of “ICU-acquired infection”?
No full textPurpose: Varicella-zoster virus (VZV) can cause a wide range of neurological complications, including meningoencephalitis, upon reactivation. The objective of this report is to alert physicians of the possibility of VZV recurrence with meningoencephalitis occurring during hospitalization in an intensive care unit (ICU) setting. Material and methods: Clinical observation of one patient. Case report: A 65 years old man was admitted to the ICU for subarachnoid hemorrhage. Although the initial treatment plan proved successful, the patient experienced numerous, mainly septic, complications. After stabilization, neurological impairment was observed with spontaneous eye opening without contact and no motor response, apart from sedation. Cerebrospinal fluid (CSF) PCR assay was positive for VZV. Intravenous acyclovir was administered for 14 days. Neurological status gradually improved with the patient showing eye and mouth opening on request as well as recovery of basic speech with one-word responses. Quantitative PCR assays showed significant decrease of VZV. EEG improved after treatment to show clear reactivity, but the abnormalities at baseline were non-specific of VZV meningoencephalitis. No new focal lesion was identified on MRI that could be linked to VZV meningoencephalitis. The patient recovered from VZV meningoencephalitis, but he finally died 44 days later, following cardiac arrest, with no reactivation of VZV infection. Conclusion: VZV meningoencephalitis may occur during hospitalization, especially during prolonged ICU stay which may be due to reactivation associated with sepsis-induced immunosuppression. It might be underestimated as MRI and EEG seem poorly contributive to the diagnosis, so CSF PCR analysis is the cornerstone exploration
