Les actualités sur les polyneuropathies axonales en 2010

During 2010, 15 articles were published which focused on chronic sensorimotor axonal neuropathy; some will be discussed in this review. Clinical diagnosis from signs and symptoms seems to be excessively variable, often overestimating the incidence of diabetic sensorimotor polyneuropathy. Long-term use of Metformin is associated with malabsorption of vitamin B12. Metformin exposure may be a iatrogenic cause for exacerbation of peripheral neuropathy in patients with type 2 diabetes. The neuroprotective role of vitamin E against cisplatinperipheral neurotoxicity has been suggested by a phase III study. Metallosis after hip arthroplasty with a cobalt-chromium alloy prosthesis can cause progressive sensory disturbance, hearing loss and hypothyroidism. The effects of electrical stimulation on neuromuscular recovery after nerve crush injury in rats do not support a benefit of the tested protocol using electrical stimulation during the period of motor nerve recovery following injury. The rate of motor vehicle accidents in patients with neuropathy, based on surveys from 260 subjects, demonstrated that 40.6% were involved in traffic accidents. Accident frequency and discomfort with driving are higher in neuropathy patients compared to age-matched national statistics. Peripheral neuropathy in primary (AL) amyloidosis may be the cause of stepwise progressive, multiple upper limb mononeuropathies.
