Occipital artery vasculitis not identified as a mechanism of occipital neuralgia-related chronic migraine headaches.
Recent evidence has shown that some cases of occipital neuralgia are attributable to musculofascial compression of the greater occipital nerve and improve with neurolysis. A mechanical interaction at the intersection of the nerve and the occipital artery may also be capable of producing neuralgia, although that mechanism remains one theoretical possibility among several. The authors evaluated the possibility of unrecognized vasculitis of the occipital artery as a potential mechanism of occipital neuralgia arising from the occipital artery/greater occipital nerve junction. ⋯ Therapeutic, IV.

Comparative StudyMicroscale electrode implantation during nerve repair: effects on nerve morphology, electromyography, and recovery of muscle contractile function.
The authors' goal is to develop a peripheral nerve electrode with long-term stability and fidelity for use in nerve/machine interfaces. Microelectromechanical systems use silicon probes that contain multichannel actuators, sensors, and electronics. The authors tested the null hypothesis that implantation of microelectromechanical systems probes does not have a detrimental effect on peripheral nerve function or regeneration. ⋯ The absence of a significant difference between the repair and the repair plus probe groups regarding histology, compound muscle action potential, walking tracks, and muscle force suggests that microelectromechanical systems electrodes are compatible with regenerating axons and show promise for establishing chemical and electrical interfaces with peripheral nerves.
