Randomized Controlled Trial Multicenter Study
Efficacy and safety of a T-type calcium channel blocker in patients with neuropathic pain: A proof-of-concept, randomized, double-blind and controlled trial.
T-type calcium channels have been shown to play an important role in the initiation and maintenance of neuropathic pain and represent a promising therapeutic target for new analgesic treatments. Ethosuximide (ETX), an anticonvulsant and a T-type channel blocker has shown analgesic effect in several chronic pain models but has not yet been evaluated in patients with neuropathic pain. ⋯ This article shows that ETX is not effective to treat neuropathic pain. Nevertheless, per-protocol analysis suggests a possible analgesic effect of ETX. Thus, our work adds significant knowledge to preclinical and clinical data on the benefits of T-type calcium channel inhibition for the treatment of neuropathic pain.

Randomized Controlled Trial
Transcranial direct current stimulation for upper limb neuropathic pain: A double-blind randomized controlled trial.
While promising, there are mixed findings for the efficacy of transcranial direct current stimulation (tDCS) for the management of chronic pain. The goal of this study was to evaluate the effect of anodal tDCS on pain and function in people with upper limb neuropathic pain. ⋯ At the group level, we found no evidence that 5 days of active 1 mA tDCS is effective for people with upper limb neuropathic pain. However, there were more individual responders in the active tDCS group compared to sham, and those who responded early after treatment experienced sustained pain relief.

Thermal Versus Super Voltage Pulsed Radiofrequency of Stellate Ganglion in Post-Mastectomy Neuropathic Pain Syndrome: A Prospective Randomized Trial.
Breast cancer is the second most common cancer world-wide following lung cancer. Post-mastectomy pain syndrome (PMPS) is one of the chronic post-surgical pain disorders (CPSP) of neuropathic character; nearly 20-50% of patients may develop PMPS. Stellate ganglion blockade has been performed as a diagnostic, prognostic, or therapeutic intervention for different pain syndromes. ⋯ Cancer breast, post mastectomy pain syndrome, stellate ganglion block, radiofrequency therapy.

Randomized Controlled TrialAnalgesic effect of intrathecal baclofen bolus on neuropathic pain in spinal cord injury patients.
GABA-ergic neurons are widely distributed throughout the central nervous system, including the spinal cord which is important for the transmission of pain impulses to the brain. Here we hypothesized that intrathecal baclofen (ITB) which is a GABA analogue might exert analgesic effects on neuropathic pain, which could be related to subtypes of pain in spinal cord injury (SCI). ⋯ ITB has analgesic effects on all subtypes of neuropathic pain and can improve interference of neuropathic pain with activities of daily living. ITB might be a promising analgesic treatment to control neuropathic pain.

Randomized Controlled TrialEfficacy and Safety of Lidocaine Infusion Treatment for Neuropathic Pain: A Randomized, Double-Blind, and Placebo-Controlled Study.
Lidocaine infusion therapy (LIT) is an effective treatment for relieving neuropathic pain (NeP). However, it remains unclear whether pain relief can be sustained through repeated lidocaine infusions. This study aimed to determine whether repeated intravenous administration of low-dose lidocaine could provide prolonged pain relief in patients with specific NeP conditions. ⋯ This study was registered at ClinicalTrials.gov, identifier NCT02597257.
