The aim of this study was to investigate corticobasal syndrome with respect to underlying pathologies, the ability of current clinical criteria to detect early stages of disease, and symptoms and signs predicting background pathologies. We retrospectively analyzed the clinicopathological findings from patients with corticobasal syndrome. We also analyzed whether those findings fulfilled the diagnostic criteria for corticobasal degeneration (CBD). Finally, we investigated characteristic clinical features that are specific to each background pathology. Of 10 consecutive autopsied patients who had corticobasal syndrome (mean age ± standard deviation, 67.9 ± 9.3 years; male:female ratio, 6:4), three had corticobasal degeneration pathology, three had progressive supranuclear palsy, three had Alzheimer's disease, and one had atypical four-repeat tauopathy. Nine patients fulfilled Mayo criteria, and all 10 patients fulfilled modified Cambridge criteria at the later stage, but only two patients fulfilled either clinical criteria within 2 years of disease onset. Five patients fulfilled the clinical criteria for possible CBD (p-CBD), and one patient fulfilled the clinical research criteria for probable sporadic CBD (cr-CBD) at the later stage. Only two patients fulfilled the criteria for either p-CBD or cr-CBD within 2 years of disease onset. Although we could not find any predictive characteristic clinical features that were specific to CBD pathology, only patients with progressive supranuclear palsy developed apraxia of eyelid opening and cerebellar ataxia. Myoclonus and memory impairment, especially if they appear at an early stage of the disease, may predict Alzheimer's disease pathology. Sensitivity of the available clinical criteria for corticobasal syndrome was poor within 2 years of disease onset.

We report the clinical and autopsy features of a 65-year-old Japanese man who clinically exhibited overlap of both neuro-Behçet's disease (NBD) and amyotrophic lateral sclerosis (ALS). The patient had a HLA-B51 serotype, a recent history of uveitis and had suffered paraparesis, sensory and autonomic disturbance, frontal signs and tremor. A brain and spine MRI study revealed a longitudinally extensive thoracic cord (Th) lesion, but no apparent intracranial abnormalities. The lesion extended ventrally from Th4 to Th9, exhibiting low intensity on T1-weighted images, high intensity on T2-weighted and fluid-attenuated inversion recovery images and gadolinium enhancement. The patient's upper and lower motor neuron signs and sensory disturbance worsened and he died 16 months after admission. At autopsy, the spinal cord and brain exhibited characteristic histopathological features of both NBD and ALS, including chronic destruction of the ventral thoracic white and gray matter, perivascular lymphocytic infiltration, binucleated neurons, lower and upper motor neuron degeneration, Bunina bodies and skein-like inclusions. Although incidental coexistence of these rare disorders could occur in an individual, this case raises the possibility of a pathomechanistic association between NBD and ALS.

This study includes an evaluation of friction on the fingers, palms, and forearms of 20 subjects using a sinusoidal motion friction evaluation system Fig. 1. The skin surfaces at points 1-6 were rubbed with a urethane contact probe. The effects of the changing water content in the stratum corneum at each position as well as the skin elastic Abstract: This study includes an evaluation of friction on the fingers, palms, and forearms of 20 subjects using a sinusoidal motion friction evaluation system. The effects of the changing water content in the stratum corneum at each position as well as the skin elastic modulus on the friction parameters were analyzed to show the factors governing friction dynamics. We observed a significant delay time (δ) and a stick-slip phenomenon during the sinusoidal motion friction processes. These dynamic phenomena are due to the softness and viscoelastic properties of human skin. The findings regarding the response of human skin to frictional stimulation under accelerated conditions facilitates a better understanding of the dynamic and mechanical properties of human skin.

A 49-year-old man presented with fever and pain, redness, swelling, and difficulty in walking. The serum C-reactive protein (CRP), creatin kinase (CK), and endotoxin levels were elevated. A blood culture revealed Edwardsiella tarda(E. tarda). Computed tomography (CT) showed subfascial and subcutaneous low-density areas in the lower legs, suggesting focal abscesses and edema. The patient was likely to have necrotizing fasciitis or cellulitis. He was successfully treated with several antibiotics and discharged after 43 days. Because E. tarda causes sepsis and fulminating necrotizing fasciitis with a high mortality rate in patients with an underlying illness, it should be considered a potentially important pathogen. The lack of an underlying illness may be a factor for a good outcome in this case.
