Introduction. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) and of the pars interna of Globus Pallidus (GPi) is used to improve parkinsonian symptoms and attenuate levodopa-induced motor complications in Parkinson's disease (PD) (DBS for PD study group, 2001). It is still not clear what the best anatomic structures to stimulate are or what the physiologic effects of DBS are. ⋯ Most patients remained were chronically treated with bilateral stimulation of both targets. Conclusion. We conclude that DBS of STN and GPi was effective, with most patients treated chronically with both targets stimulated.

We present here a descriptive article on the development of a national quality system for neuromodulatory techniques in the Netherlands. In 1994, due to reimbursement difficulties in the Netherlands, a Neuromodulation Working Group (WGN) undertook an initiative to develop a national quality system for neuromodulation. It was believed that with official recognition of neuromodulation as a therapy by the health authorities in the Netherlands, a quality system for monitoring would then follow. ⋯ We therefore conclude that developed quality systems can provide a basis for medical specialists to cooperate around groups of patients or diseases. These quality systems can facilitate implementation and innovation within the health care system. The role of medical specialists and their will to cooperate is essential.

Intractable neuropathic facial pain resulting from injury to the peripheral branches of the trigeminal nerve presents a significant challenge for neurologists, pain specialists, and neurosurgeons. In this paper, we describe our technique of peripheral nerve stimulation of the infraorbital and supraorbital nerves to treat patients with medically intractable facial pain. Stimulation of the infraorbital and supraorbital nerves is performed using percutaneously inserted electrodes that are positioned in the epifascial plane, traversing the course of the infraorbital or supraorbital nerves. ⋯ In patients who underwent permanent electrode implantation, stimulation resulted in long lasting pain relief; complications were rare and minor. We conclude that trigeminal branch stimulation is a simple technique that can be used in selected patients with neuropathic pain in the distribution of the infraorbital or supraorbital nerves. This procedure may provide relief of medically intractable pain, without the need for destructive procedures or more central modulation approaches.
