Treatment of neuropathic pain with the capsaicin 8% patch: Quantitative sensory testing (QST) in a prospective observational study identifies potential predictors of response to capsaicin 8% patch treatment.

Background and aims Peripheral neuropathic pain (PNeP) is a chronic and disabling condition for which no predictors of response to treatment have yet been identified. Clinical studies show that while many patients with PNeP respond positively to treatment with the capsaicin 8% patch, others do not. This study used quantitative sensory testing (QST) to determine whether any patient characteristics can predict response to treatment with the capsaicin 8% patch.

A brief, high-dose remifentanil infusion partially reverses neuropathic pain in a subgroup of post herpetic neuralgia patients.

Mechanism-based therapy for chronic pain is desperately needed. Recent basic science research demonstrated that remifentanil can reverse long-term potentiation at C-fiber synapses in the dorsal horn of rats. In this exploratory, single group study, patients with chronic post-herpetic pain were treated with a single, one-hour, high-dose remifentanil infusion.

Peripheral nerve field stimulation (PNFS) in chronic low back pain: a prospective multicenter study.

Objectives: The goal of this study was to evaluate the long-term efficacy and safety of peripheral nerve field stimulation (PNFS) for chronic low back pain (cLBP).

Materials And Methods: In this prospective, multicenter observational study, 118 patients were admitted to 11 centers throughout Austria and Switzerland. After a screening visit, all patients underwent a trial stimulation period of at least seven days before implantation of the permanent system.

Subcutaneous target stimulation (STS) in chronic noncancer pain: a nationwide retrospective study.

Stimulation of primary afferent neurons offers a new approach for the control of localized chronic pain. We describe the results with a new neurostimulation technique, subcutaneous target stimulation (STS), for the treatment of chronic focal noncancer pain. STS applies permanent electrical stimulation directly at the painful area via a percutaneous-placed subcutaneous lead.
