Peripheral nerve field stimulation for pruritus relief in a patient with notalgia paraesthetica.

This case study is presented to exemplify the application of peripheral nerve field stimulation in the treatment of recalcitrant notalgia paraesthetica. The patient was a 60-year-old woman with severe and disabling notalgia paraesthetica. The itch persisted despite the use of several medications - topical and oral. Following a successful trial of peripheral nerve field stimulation with a temporary electrode, two subcutaneous electrodes were inserted into the affected area with a battery implanted subcutaneously in her right buttock. The patient was reviewed at 5 months post implantation. She reported a greater than 85% improvement in her itch. She also reported a major improvement in her quality of life, with particular improvement in her ability to sleep through the night. This case illustrates the possible utilization of peripheral nerve field stimulation in the treatment of notalgia paraesthetica, which is a common yet poorly understood and treated condition. Replication and controlled studies are required to determine the general applicability of this approach.
