Lyme neuroborreliosis in Japan: Borrelia burgdorferi sensu lato as a cause of meningitis of previously undetermined etiology in hospitalized patients outside of the island of Hokkaido, 2010-2021.

Background And Purpose: Clinical manifestations of Lyme borreliosis (LB), caused by Borrelia burgdorferi sensu lato (Bbsl), include erythema migrans, Lyme neuroborreliosis (LNB), carditis, and arthritis. LB is a notifiable disease in Japan with <30 surveillance-reported LB cases annually, predominately from Hokkaido Prefecture. However, LB, including LNB, may be under-diagnosed in Japan since diagnostic tests are not readily available.

Nasojejunal Tube Placement for Levodopa-carbidopa Intestinal Gel Treatment by Neurologists in Patients with Advanced Parkinson's Disease: A Retrospective Observational Study.

Objective Short-term levodopa-carbidopa intestinal gel (LCIG) treatment using nasojejunal (NJ) tubes (NJ-LCIG test) is recommended for patients with advanced Parkinson's disease to ensure compatibility with this treatment system prior to permanent percutaneous endoscopic gastrojejunostomy. However, there have been no studies on NJ tube insertion by neurologists or on possible differences in treatment efficacy based on the NJ tube insertion method or tube tip position. We therefore investigated the effects of LCIG with NJ tube placement performed by a neurologist.

Quality of life assessment when considering the introduction of device-assisted therapies in advanced Parkinson's disease: A retrospective observational cross-sectional study.

Introduction: Device-aided therapy (DAT) is an established treatment for improving the quality of life (QOL) in individuals with advanced Parkinson's disease (APD). Criteria for starting DAT, including motor and non-motor symptoms, have been proposed. However, it remains unclear whether QOL differences among patients with APD influence DAT introduction.

Colocalization of TDP-43 and stress granules at the early stage of TDP-43 aggregation in amyotrophic lateral sclerosis.

TDP-43 aggregates (skeins and round inclusions [RIs]) are frequent histopathological features of amyotrophic lateral sclerosis (ALS). We have shown that diffuse punctate cytoplasmic staining (DPCS) is the earliest pathologic manifestation of TDP-43 in ALS, corresponding to nonfibrillar TDP-43 located in the rough endoplasmic reticulum. Previous in vitro studies have suggested that TDP-43 inclusions may be derived from stress granules (SGs).

Case report: Adult-onset neuronal intranuclear inclusion disease with an amyotrophic lateral sclerosis phenotype.

Amyotrophic lateral sclerosis (ALS) is one of the differential diagnoses of diseases that occur in adulthood and lead to progressive generalized muscle weakness. Neuronal intranuclear inclusion disease (NIID) is a disease in which histopathologically eosinophilic nuclear inclusion bodies are found in various systems. Both familial and sporadic forms of the disease have been reported.

Slow vital capacity as a useful indicator of the prognosis after percutaneous endoscopic gastrostomy in patients with amyotrophic lateral sclerosis.

Objectives: Forced vital capacity (FVC) is recommended as a respiratory function test in patients with amyotrophic lateral sclerosis (ALS). However, in ALS associated with orofacial palsy, FVC may be an unreliable test. Slow vital capacity (SVC) is an easier and more reliable test even in cases with bulbar symptoms.

Campylobacter coli infection causes spinal epidural abscess with Guillain-Barré syndrome: a case report.

Background: Guillain-Barré syndrome (GBS) and spinal epidural abscess (SEA) are known as mimics of each other because they present with flaccid paralysis following an infection; however, they differ in the main causative bacteria. Nevertheless, the two diseases can occur simultaneously if there is a preceding Campylobacter infection. Here, we report the first case of SEA with GBS following Campylobacter coli infection.

Phytobezoar Associated with Levodopa-carbidopa Intestinal Gel Infusion in Patients with Parkinson's Disease: A Case Report and Literature Review.

Continuous intrajejunal infusion of levodopa-carbidopa intestinal gel (LCIG) is an established device-aided therapy for advanced Parkinson's disease (PD). Phytobezoar associated with LCIG is a rare device-related complication and presents with exacerbations of gastrointestinal and PD symptoms. We herein report the case of a phytobezoar that was formed at a knot on the pigtail-shaped J-tube and developed only in association with postprandial abdominal pain, similar to a feeling of a tube being pulled in without an exacerbation of PD symptoms.

Subarachnoid Hemorrhage Caused by Ruptured Aneurysm of the Artery of Adamkiewicz: a Case Report.

A 66-year-old man presented with a 6-day history of progressive posterior cervical pain that included lower back pain and fever. Neurological examinations revealed neck stiffness. Computed tomography demonstrated convexity subarachnoid hemorrhage.

Sensory Nerve Conduction Study with Inching Test in Palmar Digital Neuropathy.

Mild palmar digital neuropathy may be underestimated because selective nerve conduction studies (NCS) of the palmar digital nerve are challenging. We herein report two cases of palmar digital neuropathy. We performed sensory NCS in each finger using the standard approach.

GABA storage and release in the medial globus pallidus in L-DOPA-induced dyskinesia priming.

Levo-dihydroxyphenylalanine (L-DOPA) is the most effective treatment for Parkinson's disease; however, most patients develop uncontrollable abnormal involuntary movements known as L-DOPA-induced dyskinesia. L-DOPA-induced dyskinesia can be reduced by pallidotomy of the medial globus pallidus or pallidal deep brain stimulation, suggesting that the medial globus pallidus plays a significant role in the development of L-DOPA-induced dyskinesia. In the present study, the pathological changes of the medial globus pallidus in L-DOPA-induced dyskinesia were studied in rat models of Parkinson's disease (unilateral 6-hydroxydopamine lesioning) and L-DOPA-induced dyskinesia (L-DOPA injection in Parkinson's disease-model rats twice daily for 2 weeks, confirmed by display of dyskinesia-like abnormal involuntary movements).

Assessing the relationship between non-motor symptoms and health-related quality of life in Parkinson's disease: a retrospective observational cohort study.

Objectives: Non-motor symptoms (NMSs) negatively impact the health-related quality of life (HrQOL) of patients with Parkinson's disease (PD). The Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) is a comprehensive scale for evaluating PD. It remains unclear whether the NMSs evaluated with MDS-UPDRS are predictive of HrQOL.

Hypoglossal Nerve Palsy due to Compression by a Persistent Primitive Hypoglossal Artery: Case Report.

A 51-year-old Japanese woman was admitted to our hospital because of speech difficulty following severe headache. Neurological examination showed dysarthria and tongue weakness on the right side, indicating right hypoglossal nerve palsy. Needle electromyography of the right side of the tongue showed fibrillation potentials.

[Continuous hyperCKemia without calf muscle hypertrophy associated with S1 radiculopathy].

A 72-year-old man presented with continuous hyperCKemia and intermittent claudication. He exhibited no calf muscle hypertrophy at that time or afterward. Other than an increased creatine kinase (CK) level (1,525 U/l), none of the laboratory tests was abnormal, including that for myositis-related autoantibodies.

Helicopter Transport for Patients with Cerebral Infarction in Rural Japan.

Objectives: Physician-staffed helicopter transport is faster than ground transport and allows for prompt medical care of patients in rural areas. In this study, we evaluated the relationship between helicopter transport and the prognosis of patients with acute cerebral infarction in rural Japan.

Methods: This retrospective, observational study included 546 patients with acute cerebral infarction attending Aomori Prefectural Central Hospital, which serves a rural region of Japan.

Subacute Sensory Ataxic Neuronopathy With Thymoma Presenting Marked Improvement After Steroid Therapy.

Subacute sensory ataxic neuronopathy is a well-known form of paraneoplastic syndrome. Most sensory neuronopathies are associated with small cell lung cancer and anti-Hu antibodies, and usually show only slight improvement with immunotherapy. To date, there have been few reports of neuropathy associated with thymoma and no treatment strategy has been established for thymoma-related neuropathy.

Atypical globular glial tauopathy with a combination of types I and II pathology.

Globular glial tauopathy (GGT) is a group of 4-repeat tauopathies characterized by widespread globular glial inclusions (GGIs). GGT is now classified into three subtypes based on the distribution and morphology of the GGIs. We report an autopsy case of GGT in an 85-year-old woman who presented with semantic dementia, a rare phenotype in GGT.

Evaluation of cerebral blood flow in older patients with status epilepticus using arterial spin labeling.

Introduction: Although older patients with status epilepticus (SE) have a high mortality rate and poor outcome, it is difficult to perform emergent electroencephalography (EEG) to diagnose SE in community hospitals. Arterial spin labeling (ASL) is a non-invasive magnetic resonance imaging (MRI) technique that can rapidly assess cerebral blood flow (CBF). Further, ASL can detect increased CBF in the ictal period.
