Guillain-Barré syndrome in the course of EBV infection after kidney transplantation--a case report.

Background: Neurological complications are quite frequent in patients after solid organ transplantation, mostly affecting the central nervous system, and less frequently the peripheral nerves. Guillain-Barré syndrome (GBS), a reactive autoimmune disease of the nervous tissue, is the most common cause of acute polyneuropathy in adults following a viral or bacterial infection. GBS has been also linked to neurotoxic adverse effects of calcineurin inhibitors.

Impact of CT based attenuation correction on quantitative assessment of DaTSCAN ((123)I-Ioflupane) imaging in diagnosis of extrapyramidal diseases.

The quality of visually and semi-quantitatively assessed DaTSCAN images is crucial for differential diagnostics of extrapyramidal diseases. Neuroimaging with the use of presynaptic tracers of the dopaminergic system provides evidence of nigrostriatal degeneration and may support the clinical diagnosis of Parkinsonism. During the last two years (2007-2008) we tried to elaborate the optimal methodology of SPECT/CT examination with the use of DaTSCAN ((123)I-Ioflupane), and we sought to evaluate the effect of the reconstruction and attenuation correction method on semi-quantitative measures of relative uptake in the striatum.
