Aortic involvement in relapsing polychondritis

Conclusions This study underlines that aortic involvement is severe in RP. Furthermore, we suggest that RP patients exhibiting poor prognostic factors, including panaortitis and higher values of ESR, may require more aggressive therapy.

We describe the case of a 50-year old woman presenting to the emergency department with right lower abdominal pain. CT-scan showed an obstruction without clear underlying cause. The hypothesis of obstruction due to intestinal adhesions without strangulation was assumed and non-operative management lead to recovery and dismissal of the patient. However, she presented 3 weeks later with identical complaints, this time showing a terminal ileitis on CT-scan. Surprisingly, a toothpick perforating the terminal ileum was found during endoscopy and could by removed. A clinician should think of foreign body ingestion when patients ...

Irradiation with swift heavy oxygen beam has been performed at four different fluences of 1×1011 ions/cm2, 3×1011 ions/cm2, 1×1012 ions/cm2 and 2×1012 ions/cm2. BPE films are made by solution cast method. Electrochemical properties of non-irradiated and ir...

In the work, novel Li:CuO/reduced graphene oxide flexible electrodes demonstrate enhanced electrical conductivity and specific capacitance obtained via the incorporation of Li into CuO particles. The degree of capacitance enhancement increases with scan rate, reaching a maximum value of 40% at a high scan rate of 50...

Abnormal oxidation behavior of Fe in the Ti(C,N)- 304ss cermet was observed for the first time, and it was investigated by field emission scanning electron microscope (FESEM) and 3D laser scanning confocal microscope (LSCM). A gap was generated in the TiO2/304ss interface due to t...
