Chicken bone is one of the most frequent foreign bodies (FB) associated with upper esophageal perforation. Upper digestive tract penetrating FB may lead to life threatening complications and requires prompt management. We present the case of a 52-year-old man who sustained an upper esophageal perforation associated with cervical cellulitis and mediastinitis. Following CT-scan evidence of FB penetrating the esophagus, the impacted FB was successfully extracted under rigid esophagoscopy. Direct suture was required to close the esophageal perforation. Cervical and mediastinal drainage were made immediately. Naso- gastric tube decompression, broad-spectrum intravenous antibiotics, and parenteral hyperalimentation were administered for 10 d postoperatively. An esophagogram at d 10 revealed no leak at the repair site, and oral alimentation was successfully reinstituted. Conclusion: Rigid endoscope management of FB esophageal penetration is a simple, safe and effective procedure. Primary esophageal repair with drainage of all affected compartments are necessary to avoid life-threatening complications.

●AIM:To study if one of the two molecules could lead to a lower number of follow up visits and intra-vitreous injection(IVI)with the same efficacy.●METHODS:ELU(or"elected"in French)study is a retrospective study conducted in real life in patients presenting suboptimal response after ranibizumab IVI(phase 1)and secondary switched to aflibercept(phase 2).The number of follow up visits and IVI were compared in both *** acuity(VA)evolution and"switching"reasons were secondary analyzed.●RESULTS:We retrospectively included data of 33 patients(38 eyes)with age-related macular degeneration(AMD;mean age:77±7.7 y).The number of monthly follow up visits[median(Q1;Q3)]:was significantly lower with aflibercept(phase 2),respectively 1.0(0.81;1.49)visits in phase 1,versus 0.79(0.67;0.86)visits in phase *** median number of monthly IVI also significantly decreased in phase 2,respectively 0.67(0.55;0.90)IVI in phase 1,versus 0.55(0.45;0.67)IVI in phase *** mean VA evolution(VA final-VA initial)was similar in both phases,(P>0.05).Whatever the reason for"switching"(loss of efficacy,tachyphylaxis,tolerance problems),there was no incidence on VA evolution over the time.●CONCLUSION:Our results show that switching from ranibizumab to aflibercept in"suboptimal"patients significantly reduce the number of follow up visits and IVI,with a comparable *** decrease in visit number could improve patients’quality of life and reduce surgical risk by reducing the number of injections.

How rock samples can be representative of in situ condition:A case study of Callovo-Oxfordian claystones

Within the framework of feasibility studies for a reversible, deep geological repository of high-and intermediate-level long-lived radioactive waste(HLW, IL-LLW), the French National Radioactive Waste Management Agency(Andra) is investigating the Callovo-Oxfordian(COx) formation near Bure(northeast part of France) as a potential host rock for the repository. The hydro-mechanical(HM) behaviour is an important issue to design and optimise different components of the disposal such as shaft, ramp, drift,and waste package disposal facilities. Over the past 20 years, a large number of laboratory experiments have been carried out to characterise and understand the HM behaviours of COx claystones. At the beginning, samples came from deep boreholes drilled at the ground surface with oil base mud. From2000 onwards, with the launch of the construction of the Meuse/Haute-Marne Underground Research Laboratory(MHM URL), most samples have been extracted from a large number of air drilled boreholes in the URL. In parallel, various constitutive models have been developed for modelling. The thermohydro-mechanical(THM) behaviours of the COx claystones were investigated under different repository conditions. Core samples are subjected to a complex HM loading path before testing, due to drilling, conditioning and preparation. Various kinds of effects on the characteristics of the claystones are highlighted and discussed, and the procedures for core extraction and packaging as well as a systematic sample preparation protocol are proposed in order to minimise the uncertainties on test results. The representativeness of the test results is also addressed with regard to the in situ rock mass.

The chemical compositions of Ag-Er co-doped phosphate and silicate glasses were investigated with X-ray photoelectron spectroscopy with the purpose to identify the chemical state of silver. The analysis of the Ag 3d core lines show the presence of nanometer-sized silver particles in each of the annealed samples,even if these Ag 3d lines appear to be very different from each other. We explain these results as a different interaction of silver with the two glasses matrix,which leads to a different nucleation rate of the Ag clusters.
