Spinal cord stimulation for gait impairment in Parkinson Disease: scoping review and mechanistic considerations.

Objective: Advanced Parkinson's Disease (PD) is associated with Parkinson's Disease gait impairment (PDg), which increases the risk for falls and is often treatment-refractory. Subthalamic nucleus (STN) and globus pallidus pars interna (GPi) deep brain stimulation (DBS) often fails to improve axial symptoms like PDg. Spinal cord stimulation (SCS) has been suggested to improve PDg.

Health consequences of involuntary exposure to benzene following a flaring incident at British Petroleum refinery in Texas City.

Objective: Environmental exposure to benzene can lead to deleterious effects on many biological systems including blood-forming organs, liver, and kidneys. The authors sought to investigate the health consequences of benzene exposure following a flaring incident that occurred at the British Petroleum (BP) refinery in Texas City, TX.

Subjects And Participants: A cohort of subjects who were exposed to a daily sustained release of toxic chemicals including more than 7,711 kg (17,000 lb) of benzene for a total duration of 40 days due to BP's flaring incident.
