Spinal cord stimulation is an important therapy option for the treatment of chronic neuropathic pain of spinal or peripheral etiology. As with any implantable device, complications may arise. These must be promptly identified and managed to maintain patients in successful therapy. ⋯ Lead migration is one of the most common complications of spinal cord stimulation, and left untreated can lead to loss of therapy and possible device explant. A strategy for correcting this issue is needed, and we present an unusual case to consider when faced with a loss of therapy from lead migration.

It has been proposed that the expression of pain-related suffering may lead to an enhanced focus on oneself and reduced attention toward the external world. This study aimed at investigating whether experimentally induced painrelated suffering may lead persons to withdraw into themselves, causing a reduced focus on external stimuli as reflected by impaired performance in a facial recognition task and heightened perception of internal stimuli measured by interoceptive awareness. ⋯ Our results suggest that long-lasting and intense painful stimuli, which induce suffering, lead to attentional shifts leading to withdrawal from others. These findings contribute to a better understanding of the social dynamics of pain and pain-related suffering.

Randomized Controlled Trial Multicenter Study
Efficacy of recurrent transcutaneous magnetic stimulation in the treatment of diabetic peripheral neuropathy: Multicenter randomized trial.
Transcutaneous magnetic stimulation (TCMS) is successful in decreasing pain in several neurologic conditions. This multicenter parallel double-blind phase II clinical trial is a follow-up to a pilot study that demonstrated pain relief in patients with diabetic peripheral neuropathy (DPN) treated with TCMS. ⋯ In this two-arm trial, TCMS failed to demonstrate a significant benefit over sham in patient reported pain suggesting a substantial placebo effect in our previous pilot study.

The potential benefits of electroconvulsive therapy (ECT) in chronic pain and several theories for its mechanism have been reported in the past, but mixed findings have also been reported. In the current systematic review and case series, our primary aim was to assess whether pain and functional outcomes are improved after ECT in patients with chronic pain. Secondary objectives included examining whether psychiatric improvement, specific pain diagnoses, and demographic or medical characteristics were associated with differences in pain treatment response. ⋯ ECT may be offered to patients with certain pain conditions who have not responded sufficiently to conventional therapies, particularly when comorbid mood symptoms are present. Improved documentation practices on the outcomes in chronic pain patients receiving ECT will help generate more studies that are needed on this topic.

Spinal cord stimulation (SCS) is conventionally placed at either cervical or thoracic spinal regions to treat chronic pain. However, for patients with multiarea pain, concomitant cervical and thoracic SCS (ctSCS) may be necessary to provide sufficient coverage. It remains unknown whether ctSCS is effective and safe. Thus, we aimed to survey the existing literature and assess the efficacy and safety of ctSCS. ⋯ Despite the limited evidence available, ctSCS seems to be effective and generally well tolerated. The dearth of relevant primary literature illustrates a knowledge gap, and future studies are needed to better clarify the efficacy and safety profile of this SCS variant.
