Combining low-dose radiation therapy and magnetic resonance guided focused ultrasound to reduce Amyloid-β deposition in Alzheimer's Disease
No full textAmyloid-β deposition is one of the neuropathological hallmarks of Alzheimer's disease (AD), but pharmacological strategies toward its reduction are poorly effective.Preclinical studies indicate that low-dose radiation therapy (LD-RT) may reduce brain amyloid-β. Animal models and proof-of-concept preliminary data in humans have shown that magnetic resonance guided focused ultrasound (MRgFUS) can reversibly open the blood-brain-barrier and facilitate the delivery of targeted therapeutics to the hippocampus, to reduce amyloid-β and promote neurogenesis in AD. Ongoing clinical trials on AD are exploring whole-brain LD-RT, which may damage radio-sensitive structures, i.e., hippocampus and white matter, thus contributing to reduced neurogenesis and radiation-induced cognitive decline. However, selective irradiation of cortical amyloid-β plaques through advanced LD-RT techniques might spare the hippocampus and white matter. We propose combined use of advanced LD-RT and targeted drug delivery through MRgFUS for future clinical trials to reduce amyloid-β deposition in AD since its preclinical stages

Abnormalities of sensory processing and sensorimotor interactions in secondary dystonia: A neurophysiological study in two patients
No full textExperimental data suggest that abnormalities of sensory processing and sensorimotor integration may play a role in the genesis of symptoms in primary dystonia. We studied 2 patients with dystonia secondary to lesions in the somatosensory pathways. We documented sensorimotor alterations in these patients that strongly resemble those found in primary dystonia. Our data are consistent with the hypothesis that abnormalities in sensorimotor processing may contribute to the pathogenesis of dystonic conditions.Experimental data suggest that abnormalities of sensory processing and sensorimotor integration may play a role in the genesis of symptoms in primary dystonia.

The diagnostic value of nerve ultrasound in an atypical palmar cutaneous nerve lesion
No full textDetailed knowledge of the fascicular anatomy of peripheral nerves is important for microsurgical repair and functional electrostimulation.We report a patient with a lesion on the left palmar cutaneous branch of the median nerve (PCBMN) and sensory signs expanding outside the PCBMN cutaneous innervation territory. Nerve conduction study showed the absence of left PCBMN sensory nerve action potential, but apparently, no median nerve (MN) involvement. Nerve ultrasound documented a neuroma of the left PCBMN and a coexistent lateral neuroma of the left MN in the carpal tunnel after the PCBMN left the main nerve trunk.Nerve ultrasound may offer important information in patients with peripheral nerve lesions and atypical clinical and/or nerve conduction study findings. The present case may shed some light on the somatotopy of MN fascicles at the wrist
