[Rehabilitation therapy for aquaporin-4 antibody positive neuromyelitis optica spectrum disorders].

Forty-five cases with aquaporin-4 antibody-positive neuromyelitis optica spectrum disorders (NMOSD) who underwent convalescent rehabilitation were studied. After excluding three cases with recurrence during rehabilitation treatment, the Expanded Disability Status Scale of Kurtzke improved a median of 1 point. Corticosteroids were the most used disease-modifying drugs (DMDs).

Clinical manifestations and outcomes associated with a high 2HELPS2B score in patients with acute impaired consciousness.

Purpose: The 2HELPS2B score is an invaluable tool for assessing seizure risk in critically ill patients with unconsciousness. However, this can be challenging for non-epileptologists to use owing to its reliance on electroencephalogram (EEG) analysis. Thus, identifying clinical manifestations associated with high 2HELPS2B scores is crucial.

Immediate and 6-month seizure outcomes following first and second SARS-CoV2 mRNA vaccinations: A multicenter study with a nationwide survey.

Objective: This study aimed to identify seizure outcomes in people with epilepsy (PWE) following severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) messenger RNA vaccination.

Methods: We examined PWE (n = 332, age ≥ 14 years) treated in four tertiary hospitals between 2021 and 2022 to assess the incidence of seizure worsening following vaccination using closed questions. We identified the clinical factors associated with worsening and 6-month vaccination outcomes.

Impact of anatomical variations on ultrasonographic reference values of lower extremity peripheral nerves.

Introduction/aims: Cross-sectional area (CSA) reference values using ultrasonography vary widely for lower extremity peripheral nerves. In addition, there is a lack of data on the muscular branches of the tibial nerve and the anatomical variations of the sural nerve. We aimed to evaluate the ultrasonographic reference values for lower extremity peripheral nerves considering different anatomical variations and physical factors.

HLA genotype-clinical phenotype correlations in multiple sclerosis and neuromyelitis optica spectrum disorders based on Japan MS/NMOSD Biobank data.

HLA genotype-clinical phenotype correlations are not established for multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSD). We studied HLA-DRB1/DPB1 genotype-phenotype correlations in 528 MS and 165 NMOSD cases using Japan MS/NMOSD Biobank materials. HLA-DRB1*04:05, DRB1*15:01 and DPB1*03:01 correlated with MS susceptibility and DRB1*01:01, DRB1*09:01, DRB1*13:02 and DPB1*04:01 were protective against MS.

Prospective Memory Deficits in Multiple Sclerosis: Voxel-based Morphometry and Double Inversion Recovery Analysis.

Objective Prospective memory (PM) is an important social cognitive function in everyday life. PM is one of the most affected cognitive domains in multiple sclerosis (MS) patients. Gray matter (GM) atrophy and plaques have been attracting attention for various cognitive impairments in MS patients.

Safety and efficacy of rituximab in neuromyelitis optica spectrum disorders (RIN-1 study): a multicentre, randomised, double-blind, placebo-controlled trial.

Background: Pharmacological prevention against relapses in patients with neuromyelitis optica spectrum disorder (NMOSD) is developing rapidly. We aimed to investigate the safety and efficacy of rituximab, an anti-CD20 monoclonal antibody, against relapses in patients with NMOSD.

Methods: We did a multicentre, randomised, double-blind, placebo-controlled clinical trial at eight hospitals in Japan.

Initial deterioration and intravenous methylprednisolone therapy in patients with myasthenia gravis.

Introduction: In myasthenia gravis (MG) patients on intravenous methylprednisolone (IVMP) therapy, initial deterioration should be carefully monitored because it may cause myasthenic crisis. The aim of this study was to investigate the onset, duration and related factors of initial deterioration from the first IVMP in MG patients.

Methods: A total dose of IVMP in the first cycle of 750 mg or less, over 750 to 1500 mg, and over 1500 to 3000 mg was used in the analysis.

Usefulness of Histogram-Profile Analysis in Ring-Enhancing Intracranial Lesions.

Background: Several intracranial pathologies present as a ring-enhancing lesion on conventional magnetic resonance imaging (MRI), creating diagnostic difficulty. We studied the characteristics of the anatomical border of gadolinium enhancement on T1-weighted imaging (WI) and hypointensity on T2WI to employ a simple technique of histogram-profile analysis of MRI for differentiation of various ring-enhancing intracranial lesions.

Methods: After approval from the institutional review board, preoperative MRI (T2WI, postcontrast T1WI) scans were analyzed retrospectively in 18 patients with histologically confirmed brain abscess, 66 glioblastomas, 46 brain-metastases, and 16 tumefactive multiple sclerosis (MS).

Controlling nutritional status score for predicting 3-mo functional outcome in acute ischemic stroke.

Background: Malnutrition is an independent risk factor for poor outcomes in patients with acute ischemic stroke. However, the indicator of malnutrition has not yet been established. We investigated the relationship between the Controlling Nutritional Status score, a useful prognostic measure of malnutrition in patients with cardiovascular diseases and malignant tumors, and functional outcomes in patients with acute ischemic stroke.

Antithrombotic Therapy Strategy for Cancer-Associated Ischemic Stroke: A Case Series of 26 Patients.

Background: The risk of complications from thromboembolism is increased for patients with malignancy. Cancer-associated stroke is also a serious issue with regard to the management of patients with cancer because stroke incidence often causes disabilities that affect daily life and cancer treatment strategy.

Methods: Between March 2011 and September 2017, 328 patients with acute ischemic stroke were registered to our hospital.

Intravenous immunoglobulin for maintenance treatment of multifocal motor neuropathy: A multi-center, open-label, 52-week phase 3 trial.

Case Report: A 66-year-old man with acute ischemic stroke in the setting of lung adenocarcinoma developed acute-onset deep vein thrombosis (DVT) of the lower limbs after changing to warfarin from a heparin combination. The diagnosis of warfarin-resistant DVT was established based on the laboratory data and clinical evaluation. Heparin administration resulted in good control of thrombin regulation.

The Multidisciplinary Swallowing Team Approach Decreases Pneumonia Onset in Acute Stroke Patients.

Dysphagia occurs in acute stroke patients at high rates, and many of them develop aspiration pneumonia. Team approaches with the cooperation of various professionals have the power to improve the quality of medical care, utilizing the specialized knowledge and skills of each professional. In our hospital, a multidisciplinary participatory swallowing team was organized.

Insights from the ganglionic acetylcholine receptor autoantibodies in patients with Sjögren's syndrome.

Objective: It is not known whether autonomic neuropathy is a feature of Sjögren's syndrome (SS) or whether it is related to circulating antiganglionic acetylcholine receptor (gAChR) antibodies. The goal of the present study was to investigate the autonomic dysfunction in patients with SS and the associations between autonomic dysfunction, anti-gAChR antibodies, and clinical features of SS.

Methods: (1) The first observational study tested for the presence of gAChR antibodies in the serum samples from 39 patients with SS (absent information regarding autonomic symptoms) and healthy volunteers.

A Case of Recurrent Ischemic Stroke Involving Subacute, Progressive Intracranial Cerebral Arterial Sclerosis Prior to Diagnosis with JAK2-mutated Polycythemia Vera.

Case Report: A 58-year-old man presenting with no vascular risk factors visited our hospital with right hemiparesis and total aphasia. Diffusion-weighted magnetic resonance imaging of the brain showed multiple hyperintensities in watershed distributions in the left hemisphere. Magnetic resonance angiography (MRA) revealed stenosis of the middle cerebral artery, despite normal MRA findings 2 months prior.

Tongue thickness evaluation using ultrasonography can predict swallowing function in amyotrophic lateral sclerosis patients.

Objective: Dysphagia is a critical issue in amyotrophic lateral sclerosis (ALS) patients. An evaluation of swallowing function is important for assessing the risk of aspiration. We investigated the validity of tongue sonography compared with videofluoroscopic examination for ALS patients.
