TL;DR: Evaluation and treatment of swallowing disorders, and how best to identify and treat these disorders and their symptoms is investigated.
Abstract: The effects of laryngotracheoesophageal cleft, rheumatoid arthritis, gastroesophageal reflux disease, supracricoid partial laryngectomy with cricohyoidopexy, and postsurgical unilateral recurrent nerve paralysis on swallowing function are examined. Procedures for screening patients for symptoms of s

TL;DR: Using a radiologic technique, the position and pattern of movement of the diaphragm have been evaluated in three adult volunteers, both awake and anesthetized, during spontaneous ventilation and with muscle paralysis and mechanical ventilation.

TL;DR: Several clinical variants of this demyelinating polyneuropathy have been described, the electrophysiologic aspects better understood, and the immunologic basis clarified, but the diagnosis is still made by clinical acumen and experience.
Abstract: WITH the virtual elimination of poliomyelitis, Guillain—Barre syndrome has become the most common cause of acute generalized paralysis, with an annual incidence of 0.75 to 2 cases per 100,000 population. Several clinical variants of this demyelinating polyneuropathy have been described, the electrophysiologic aspects better understood, and the immunologic basis clarified, but the diagnosis is still made by clinical acumen and experience. The eponym derives from the description in 1916 by G. Guillain and J.A. Barre, then French army neurologists, and A. Strohl, who performed the electrophysiologic recordings1; it remains useful because of uncertainty about the cause and pathogenesis of . . .

TL;DR: It is reported that a single injection of a VEGF-expressing lentiviral vector into various muscles delayed onset and slowed progression of ALS in mice engineered to overexpress the gene coding for the mutated G93A form of the superoxide dismutase-1 (SOD1G93A).
Abstract: Amyotrophic lateral sclerosis (ALS) causes adult-onset, progressive motor neuron degeneration in the brain and spinal cord, resulting in paralysis and death three to five years after onset in most patients. ALS is still incurable, in part because its complex aetiology remains insufficiently understood. Recent reports have indicated that reduced levels of vascular endothelial growth factor (VEGF), which is essential in angiogenesis and has also been implicated in neuroprotection, predispose mice and humans to ALS. However, the therapeutic potential of VEGF for the treatment of ALS has not previously been assessed. Here we report that a single injection of a VEGF-expressing lentiviral vector into various muscles delayed onset and slowed progression of ALS in mice engineered to overexpress the gene coding for the mutated G93A form of the superoxide dismutase-1 (SOD1(G93A)) (refs 7-10), even when treatment was only initiated at the onset of paralysis. VEGF treatment increased the life expectancy of ALS mice by 30 per cent without causing toxic side effects, thereby achieving one of the most effective therapies reported in the field so far.

TL;DR: It is shown that neuromodulation of the sub-threshold motor state of excitability of the lumbosacral spinal networks was the key to recovery of intentional movement in four of four individuals diagnosed as having complete paralysis of the legs.
Abstract: Previously, we reported that one individual who had a motor complete, but sensory incomplete spinal cord injury regained voluntary movement after 7 months of epidural stimulation and stand training. We presumed that the residual sensory pathways were critical in this recovery. However, we now report in three more individuals voluntary movement occurred with epidural stimulation immediately after implant even in two who were diagnosed with a motor and sensory complete lesion. We demonstrate that neuromodulating the spinal circuitry with epidural stimulation, enables completely paralysed individuals to process conceptual, auditory and visual input to regain relatively fine voluntary control of paralysed muscles. We show that neuromodulation of the sub-threshold motor state of excitability of the lumbosacral spinal networks was the key to recovery of intentional movement in four of four individuals diagnosed as having complete paralysis of the legs. We have uncovered a fundamentally new intervention strategy that can dramatically affect recovery of voluntary movement in individuals with complete paralysis even years after injury.
