Observational Study
Validation of the QUEST for German-speaking countries.
To explore the clinimetric attributes of the German version of the quality of life in essential tremor (ET) questionnaire (QUEST) as a tremor-specific measure of quality of life. ⋯ The QUEST German version has, despite recognized data quality problems, satisfactory acceptability and internal consistency as a whole. The correlation analysis showed that tremor in the head, voice and right hand was moderately associated with quality of life.

Little is known about injury of the corticobulbar tract (CBT) in stroke patients. We attempted to investigate injury of the CBT in patients with dysarthria following cerebral infarct, using diffusion tensor tractography (DTT). ⋯ We demonstrated injury of the CBT in patients with dysarthria following cerebral infarct in the corona radiata using DTT. This result indicates the importance of CBT evaluation for dysarthria in patients with cerebral infarct. Therefore, we suggest that evaluations of the CBT using DTT would be useful for patients with dysarthria following cerebral infarct.

Review Case Reports
Paraneoplastic neuromyelitis optica spectrum disorders: three new cases and a review of the literature.
Neuromyelitis optica spectrum disorders (NMOSD) occasionally develop in patients with tumor in relation to aquaporin-4 IgG (AQP4-IgG), representing a new paraneoplastic phenomenon. We reported three patients with paraneoplastic NMOSD and provided a comprehensive review of the literature. A total of 34 cases with paraneoplastic NMOSD were identified from our own case database (n = 3) and the previous literature (n = 31). ⋯ Breast carcinoma is the most common tumor associated with paraneoplastic NMOSD, accounting for nearly a third of all types of tumors. Paraneoplastic NMOSD usually involves medulla oblongata and cervical spinal cord. We recommend adding AQP4-IgG as an onconeural antibody, but its clinical utility warrants further investigations.

To determine if the non-motor sections of the Movement Disorder Society's (MDS) version of the Unified Parkinson's Disease Rating Scale (UPDRS) could supplement the original UPDRS as a patient completed assessment of changes in non-motor symptoms in Parkinson's disease (PD) patients after bilateral subthalamic nucleus (STN) deep brain stimulation (DBS). ⋯ This study provides evidence that the MDS-UPDRS non-motor sections, when completed by the patients, can supplement the original version of the UPDRS as an effective method of measuring changes in non-motor symptoms after DBS. It also reinforces the benefits of bilateral STN DBS on non-motor symptoms of PD.

Not all patients with warfarin-related acute intracranial hemorrhage (ICH) achieve full reversal of international normalized ratio (INR) after the first dose of weight-based prothrombin complex concentrate (PCC). We sought to identify factors associated with anticoagulation reversal failure after the first dose of PCC. ⋯ Obesity and elevated initial INR are independently associated with anticoagulation reversal failure using the weight-based PCC protocol in patients with warfarin-related acute ICH. Further studies are needed to determine more effective dosing protocols and individualized strategies for anticoagulation reversal after acute ICH, especially among obese patients.
