Summary The presented work aims at a radiochemical analysis of the radionuclide inventory of a solid lead target irradiated with high energetic protons in the spallation neutron facility SINQ at Paul Scherrer Institute. Lead samples from the vicinity of the beam entry have been extracted. A detailed γ-analysis shows the radial distribution of selected radionuclides relative to the incoming beam. The concentrations of these nuclides are evaluated in dependence on the proton beam profile.

Introduction: This is a case report about a severe neurological manifestation of a tropical disease that resulted in an overlap syndrome mimicking brain death. We are showing a Chikungunya (CHIKV)-associated encephalitis triggering an overlapping autoimmunological disease [antibody negative Bickerstaff's brainstem encephalitis (BBE) with Miller Fisher syndrome (MFS) and Guillain-Barré syndrome (GBS)] and the resulting complications. Until recently, CHIKV was considered to cause a relatively harmless self-limiting disease with Dengue-like symptoms (DENV). This case supports the idea of likely neuroinvasiveness of CHIKV, suggesting a potential high severity of this infection. Chikungunya shows a global development and evolution from a rarely seen pathogen toward an epidemic causing disease within only a few decades. Case Report: A 74-year-old man fell sick during his holidays in French Polynesia. He initially presented with fever and a rash, which slowly progressed to hoarseness and back pain. Within one week, the patient developed numbness of the fingertips and difficulties breathing, finally resulting in a complete irresponsive neurological state. Local physicians assumed brain death caused by a cardiac
