Difference in the Care of Patients with Amyotrophic Lateral Sclerosis With and Without Intervention from the Palliative Care Team: Observations from a Center in Japan.

Despite the significant palliative care needs for people living with amyotrophic lateral sclerosis (ALS), palliative medicine in Japan is mainly focused on oncologic disease. To compare the care provided to patients with ALS with and without intervention from the palliative care team (PCT and non-PCT groups, respectively). This is a retrospective case-control study.

Cybernic treatment with wearable cyborg Hybrid Assistive Limb (HAL) improves ambulatory function in patients with slowly progressive rare neuromuscular diseases: a multicentre, randomised, controlled crossover trial for efficacy and safety (NCY-3001).

Background: Rare neuromuscular diseases such as spinal muscular atrophy, spinal bulbar muscular atrophy, muscular dystrophy, Charcot-Marie-Tooth disease, distal myopathy, sporadic inclusion body myositis, congenital myopathy, and amyotrophic lateral sclerosis lead to incurable amyotrophy and consequent loss of ambulation. Thus far, no therapeutic approaches have been successful in recovering the ambulatory ability. Thus, the aim of this trial was to evaluate the efficacy and safety of cybernic treatment with a wearable cyborg Hybrid Assistive Limb (HAL, Lower Limb Type) in improving the ambulatory function in those patients.

An autopsy case of corticobasal degeneration with inferior olivary hypertrophy.

We report autopsy results of a female patient who was confirmed pathologically as having corticobasal degeneration (CBD). This patient presented with progressive gait disturbance at the age of 66 years, and subsequently showed parkinsonism with a right-sided predominance and dementia. She was clinically diagnosed as having possible corticobasal syndrome without palatal myoclonus throughout the disease course.

Effectiveness of Levodopa in Patients with Multiple System Atrophy and Associated Clinicopathological Features.

Objective To determine the clinicopathological features of levodopa or dopamine agonist (DA) responders with multiple system atrophy (MSA), an autopsy-confirmed diagnosis is vital due to concomitant cases of MSA and Parkinson's disease (PD). We therefore aimed to investigate the effectiveness of levodopa and DA in autopsy cases of MSA without PD and thereby clarify the clinical course, magnetic resonance imaging (MRI) findings, and pathological features of levodopa-responsive MSA cases. Methods The medical records (clinical data, MRI findings, and pathological findings) of 12 patients with MSA were obtained, and the patients were pathologically confirmed to not have PD.

Accumulation of phosphorylated TDP-43 in the cytoplasm of Schwann cells in a case of sporadic amyotrophic lateral sclerosis.

We report for the first time the presence of phosphorylated transactivation response DNA-binding protein of 43 kDa (p-TDP-43)-immunoreactive cytoplasmic inclusions in Schwann cells in an autopsy case of sporadic amyotrophic lateral sclerosis (ALS). An 81-year-old woman with no family history of neuromuscular disorders noticed difficulty in handling chopsticks due to weakness of the hands. She then developed weakness of the lower and upper limbs and dyspnea.

Delusions and visual hallucinations in a patient with Parkinson's disease with dementia showing pronounced Lewy body pathology in the nucleus basalis of Meynert.

We describe an autopsy-proven case of Parkinson's disease with dementia showing early-onset delusions and hallucinations with limbic-type Lewy body pathology. A Japanese man 72 years old at time of death, developed hand tremor at the age of 45. On neurological examination at 47 years of age, parkinsonian symptoms and signs were present.

Contiguous and symmetrical disease expansion and massive necrosis of the cerebral white matter in a patient with neuromyelitis optica.

The present report discusses the case of a woman with neuromyelitis optica (NMO) who exhibited bilateral optic neuritis, longitudinally extensive myelitis, serum anti-aquaporin-4 antibodies, and a unique pattern of white matter involvement. The disease duration was 26 years, and the patient died at the age of 65 years. Sequential magnetic resonance images obtained during the last 6 years of life revealed leukoencephalopathy-like lesions extending symmetrically and contiguously from the periventricular regions, which had begun to transform into multiple cavities with semi-annular partitions.

Somatic sprouts of the Purkinje cells in a patient with multiple system atrophy.

We describe the post mortem case of a 71-year-old Japanese woman diagnosed as having multiple system atrophy (MSA), showing somatic sprouting formation of Purkinje cells. The patient had suffered from frequent falling episodes and clumsiness of the left hand since the age of 67 years. Orthostatic hypotension and parkinsonism subsequently emerged.

Time-series analysis: variation of anti-acetylcholine receptor antibody titer in myasthenia gravis is related to incidence of Mycoplasma pneumoniae and influenza virus infections.

Objectives The exacerbating factors of myasthenia gravis (MG) are unknown. However, it has been speculated that infections may play a role in disease progression. Methods We calculated the adjusted anti-acetylcholine receptor antibody (Adj-AChR-Ab) titers (range, 0-1) in 58 MG patients between 2006 and 2012.

[Screening of autoantibodies associated with necrotizing myopathy among undiagnosed chronic myopathy].

We screened anti-signal recognition particle (SRP) and anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) antibodies among 42 patients who had undiagnosed chronic myopathy from six national hospitals. Anti-SRP and anti-HMGCR antibodies were determined by RNA immuneprecipitation and enzyme-linked immune-sorbent assay (ELISA), respectively. We identified two patients with anti-SRP antibodies (4.

Effectiveness of electric toothbrushing in patients with neuromuscular disability: A randomized observer-blind crossover trial.

Objective: To evaluate the effectiveness of an electric toothbrush for oral care in patients with neuromuscular disability.

Methods: In this randomized observer-blind crossover trial, 30 patients with neuromuscular disease performed either electric or manual toothbrushing each for 4 weeks. Plaque status (plaque control record), periodontal pocket depth, oral status (oral assessment guide), salivary bacterial count, and toothbrushing time were assessed after each period and compared between the two groups by Wilcoxon signed-rank test.

Inclusion body myositis with granuloma formation in muscle tissue.

Inclusion body myositis is a form of inflammatory myopathy. We identified 4 cases of inclusion body myositis showing granuloma formation in muscle tissue and aimed to assess the features of this atypical form of inclusion body myositis. We retrospectively reviewed consecutive patients who satisfied European Neuromuscular Centre IBM Research Diagnostic Criteria 2011.

Case Study: Somatic Sprouts and Halo-Like Amorphous Materials of the Purkinje Cells in Huntington's Disease.

We described a 63-year-old Japanese female with genetically confirmed Huntington's disease who showed unusual pathological findings in the cerebellum. This case exhibited typical neuropathological features as Huntington's disease, including severe degeneration of the neostriatum and widespread occurrence of ubiquitin and expanded polyglutamine-positive neuronal intranuclear and intracytoplasmic inclusions. The cerebellum was macroscopically unremarkable; however, somatic sprouts and halo-like amorphous materials of Purkinje cell with a large amount of torpedoes were noteworthy.
