Continuous glucose monitoring (CGM) is a method to examine glucose concentration in subcutaneous interstitial fluid sequentially. CGM can disclose glucose fluctuation (GF), which can be unrecognized in routine blood tests. A limited number of studies suggest advanced Parkinsonian syndromes (PS) is at risk of GF, however, the report of CGM in PS is scarce. We performed CGM for 72 h in 11 nondiabetic patients with advanced PS. The etiology was Parkinson's disease, multiple system atrophy, progressive supranuclear palsy, or dementia with Lewy bodies...

Heart failure and restrictive respiratory insufficiency are complications in muscular dystrophies. We aimed to assess the accuracy of the B-natriuretic peptide (BNP) for the diagnosis of decompensated heart failure in muscular dystrophy. We included patients with muscular dystrophy and chronic respiratory insufficiency admitted in the Intensive Care Unit of the Raymond Poincare hospital (Garches, France) for suspected decompensated heart failure. Thirtyseven patients were included, among them, 23 Duchenne muscular dystrophy (DMD) (62%), 10 myotonic dystrophy type 1(DM1) (27%)...

Drug-induced Parkinsonism is often reversible after withdrawal of the causative drug. Its clinical course, however, is not well understood, as the majority of cases are caused by drugs prescribed by departments outside of neurology. We reviewed 21 cases of drug-induced parkinsonism for several factors, including age, sex, causative drug and reason for prescription, department by which it was prescribed, and outcome. The age at onset ranged from 40 to 87 years, with an average Hoehn and Yahr Scale score of 4, indicating severe disability...

A 46-year-old woman developed slowly progressive tongue weakness with a pseudohypertrophic change on the right side of her tongue. She subsequently developed weakness in her proximal lower extremities, skin erythema and a sustained increase of muscle enzymes at 11 M after the onset. A biopsy of the quadriceps muscle showed necrotizing myopathy and a skin biopsy showed erythema nodosum. The present case showed characteristic clinical manifestations that may represent a rare variant of sarcoidosis.

In view of recent data on the linkage of Gas7 protein to schizophrenia, and in view of its role in neurite outgrowth, histochemical localization of the Gas7 protein was studied in normal human brain tissue using an online tissue atlas. Selective localization to neurons in the cerebral cortex was found with moderate levels in the hippocampus and caudate, but fairly low levels were noted within the human cerebellum and was limited to small granule cells as well as the neuropil of the cerebellar molecular layers...

The visual acuity loss enables the brain to access new pathways in the quest to overcome the visual limitation and this is wellknown as neuroplasticity which have mechanisms to cortical reorganization. In this review, we related the evidences about the neuroplasticity as well as cortical anatomical differences and functional repercussions in visual impairments. We performed a systematic review of PUBMED database, without date or status publication restrictions. The findings demonstrate that the visual impairment produce a compensatory sensorial effect, in which non-visual areas are related to both cross (visual congenital) and multimodal (late blind) neuroplasticity...

Dyskinesia refers to any involuntary movement, such as chorea, dystonia, ballism that affect any part of the body. Levodopa-induced dyskinesia is a neurological disorder that afflicts many patients with Parkinson disease usually 5 years after the onset of levodopa therapy and can cause severe disability. The pathophysiology of this dyskinesia is complex and not fully understood. However, the association between vitamin D and Parkinson disease is interesting. The present study was conducted to evaluate the effect of vitamin D on levodopa induced dyskinesia in patients with Parkinson's disease ...

In the current study, we report a missed diagnosis of combined chronic inflammatory demyelinating polyneuropathy (CIDP) in a patient with a cervical spinal cord lesion. At 3.5 months after the onset of symptoms, a 60-year-old female with mild motor weakness and significant weight loss underwent a surgical operation for decompression of the cervical spinal cord. However, her motor weakness was severely aggravated despite the surgical treatment, and she could not walk independently at 10 months after symptom onset...

Chorea is thought to be caused by deactivation of the indirect pathway in the basal ganglia circuit. However, few imaging studies have evaluated the basal ganglia circuit in actual patients with chorea. We investigated the lesions and mechanisms underlying chorea using brain magnetic resonance imaging (MRI) and 18 F-fluorodeoxyglucose positron emission tomography (FDG-PET). This retrospective case series included three patients with chorea caused by different diseases: hyperglycemic chorea, Huntington's disease, and subarachnoid hemorrhage...

Ten individuals suspected of having possible Alzheimer disease underwent PET imaging using 18F-Flubetapir. Only one of ten individuals had a pattern typical for normal elderly control subjects with 9 of the 10 showing a Alzheimer type pattern for the cerebral cortex yet all 10 subjects had uniformly low to absent tracer localization to the cerebellar cortex; significantly high tracer activity was noted within the subcortical white matter of the cerebellum in a symmetric manner in all cases. In consideration of studies that have shown amyloid deposits within the cerebellar cortex in 90% of pathologically proven cases of Alzheimer's disease, these findings raise questions about the actual clinical value of florbetapir PET imaging in evaluating cerebellar involvement and raises questions whether PET imaging of this tracer accurately portrays patterns of amyloid deposition, as there is rapid hepatic metabolism of the parent compound after intravenous injection...

In young adult, the most common etiology of acute ischemic brain infarction are arterial dissections and cardiogenic embolic stroke. Vertebral artery dissection without preceding trauma history is quite rare in young ischemic stroke patients. Postural headache is even more atypical presentation for vertebral artery dissection. It is often misdiagnosed as spontaneous intracranial hypotension. We described a 37-year-old male suffering from acute onset postural headache with stroke in evolution during hospitalization...
