Surgery of central sensory motor and dorsolateral frontal lobe seizures.
Ten patients who presented with dorsolateral or frontocentral seizures were studied with chronic subdural grid electrodes. Cortical mapping, sensory-evoked potentials and chronic electrocorticography were obtained for each patient. Seizures were classified as focal, regional or dipolar. ⋯ Two patients are seizure-free and 7 patients had a significant reduction in seizure frequency. One patient had no change in seizure pattern. Dorsolateral frontal lobe seizures have a focal functional anatomy and can be surgically treated by selective cortectomy.

Clinical and technical results from spinal stimulation for chronic pain of diverse pathophysiologies.
Spinal stimulation has been indicated for pain of peripheral deafferentation, but not for low-back pain. Technical and clinical records of 241 consecutive spinal stimulator recipients were reviewed, including: peripheral deafferentation pain (n = 44); predominant pain of low back, postlaminectomy (n = 96), and predominant pain of leg(s), postlaminectomy (n = 48). ⋯ For the postlaminectomy syndromes, only the technical results correlated significantly with outcome. Spinal stimulation actually yielded results as good for the 'failed back surgery syndrome' as for peripheral deafferentation pain, because newer technical methods were proven to stimulate the low back predictably.
