Background and Purpose-Numerous preclinical findings and a clinical pilot study suggest that recombinant human erythropoietin (EPO) provides neuroprotection that may be beneficial for the treatment of patients with ischemic stroke. Although EPO has been considered to be a safe and well-tolerated drug over 2 decades, recent studies have identified increased thromboembolic complications and/or mortality risks on EPO administration to patients with cancer or chronic kidney disease. Accordingly, the double-blind, placebo-controlled, randomized German Multicenter EPO Stroke Trial (Phase II/III; ClinicalTrials.gov Identifier: NCT00604630) was designed to evaluate efficacy and safety of EPO in stroke. Methods-This clinical trial enrolled 522 patients with acute ischemic stroke in the middle cerebral artery territory (intent-to-treat population) with 460 patients treated as planned (per-protocol population). Within 6 hours of symptom onset, at 24 and 48 hours, EPO was infused intravenously (40 000 IU each). Systemic thrombolysis with recombinant tissue plasminogen activator was allowed and stratified for. Results-Unexpectedly, a very high number of patients received recombinant tissue plasminogen activator (63.4%). On analysis of total intent-to-treat and per-protocol populations, neither primary outcome Barthel Index on Day 90 (Pϭ0.45) nor any of the other outcome parameters showed favorable effects of EPO. There was an overall death rate of 16.4% (nϭ42 of 256) in the EPO and 9.0% (nϭ24 of 266) in the placebo group (OR, 1.98; 95% CI, 1.16 to 3.38; Pϭ0.01) without any particular mechanism of death unexpected after stroke. Conclusions-Based on analysis of total intent-to-treat and per-protocol populations only, this is a negative trial that also raises safety concerns, particularly in patients receiving systemic thrombolysis.

Memory performance shows a correlation with relative ventricular size in RRMS patients, indicating the strategic location of the ventricle system along the structures of the limbic system and its vulnerability in MS. The PASAT and several other cognitive tests show moderate correlations with depression and fatigue, arguing for an inter relation between the cognitive functioning and the emotional state of patients. However, this relation is independent of measurable brain atrophy.

Our findings substantiate the impact of skin biopsies in defining the carrier status in CADASIL families.

Primary dystonia is a clinically and genetically heterogeneous movement disorder characterized by sustained involuntary muscle contractions causing repetitive movements and/or abnormal postures. Recently, the gene locus (DYT1) and mutation responsible for a substantial number of cases suffering from early-onset primary dystonia was described. Here we report 2 German families and 1 sporadic patient with early-onset dystonia due to the DYT1 mutation in order to illustrate the variability of clinical manifestation within this molecularly defined entity. We demonstrate that writer's cramp or focal cervical dystonia is a clinical presentation of DYT1 as well as generalized dystonia.
