Schwannoma is the most common benign tumor of peripheral nerve. Only 7% of schwannomas arise from the median nerve, and its localization in the motor branch is extremely rare. A 57-year old right-handed female presented with a carpal tunnel syndrome symptoms associated to a little painful thenar swelling in the left hand with no motor or sensory deficit. An electromyogram confirmed the clinical...

We studied eight healthy subjects with a whole-scalp 306-channel neuromagnetometer to explore the effect of motor activity from different body parts on somatosensory responses to left median nerve stimulation. The stimuli produced clear tactile sensation without any motor movement. In the rest condition, the subject had no task. During contraction conditions, the subject had to maintain submaxi...

Autonomic dysregulation is part of the complex degenerative process in amyotrophic lateral sclerosis (ALS). To investigate this, sweating was examined at rest in 39 patients with ALS in comparison with a control group. Sweat was collected over a 30 second period over the thenar and hypothenar eminences and on the sole of the foot, using a commercial device based on vapour pressure gradient. The...

INTRODUCTION To assess potential metabolic and microcirculatory alterations in critically ill patients, near-infrared spectroscopy (NIRS) has been used, in combination with a vascular occlusion test (VOT), for the non-invasive measurement of tissue oxygen saturation (StO2), oxygen consumption, and microvascular reperfusion and reactivity. The methodologies for assessing StO2 during a VOT, howev...

Methods Following a standardized physical exam using sterile gloves and a sterile stethoscope, bacterial contamination of the following regions were assessed using contact plates: stethoscope diaphragm, stethoscope tube, fingertips, thenar region, hypothenar region and back of physician’s dominant hand. Total aerobic colony count (ACC) were determined on digital photographs using a counting tool.

Because of its variable origin and course, the thenar branch median nerve is at risk during carpal tunnel release. Transection results in atrophy non-functioning opponens pollicis, abductor pollicis brevis flexor muscles. A late neurorrhaphy hypothenar fat pad flap were performed to restore conduction thus muscle function after accidental transection an open release 216 days earlier. During eig...
