The objective of this study is to review the available evidence for dorsal root ganglion (DRG) stimulation for the treatment of complex regional pain syndrome type II (CRPS II; peripheral causalgia) associated with chronic neuropathic postsurgical pain (NPP). ⋯ DRG stimulation is known to be an effective treatment for focal neuropathic pain. Currently, NPP of the foot, groin, and knee all appear to be the conditions with the most clinical experience, backed by a limited but growing body of evidence. However, prospective studies lag behind real-world clinical experience and are needed to confirm these findings.

The Feasibility and Efficacy of Ultrasound-Guided C2 Nerve Root Coblation for Cervicogenic Headache.
The cervicogenic headache is a syndrome caused by dysfunction of the upper cervical spine and its component bony, disc, and/or soft tissue elements. The C2 nerve root may play a pivotal role in cervicogenic headache. In this retrospective study, we evaluated the feasibility and efficacy of ultrasound-guided C2 nerve root coblation in managing 26 patients with cervicogenic headache. ⋯ C2 nerve coblation may provide the majority of patients with a pain relief period as long as 24 weeks. And ultrasound guidance is an efficient method with which to perform coblation.

Validity and Reliability of the Fibromyalgia Rapid Screening Tool Among Individuals with Chronic Daily Headache: A Clinic-Based Study.
Fibromyalgia is a common chronic pain disorder typically associated with headache disorders, particularly chronic daily headache. However, fibromyalgia is typically underdiagnosed and undertreated. The Fibromyalgia Rapid Screening Tool questionnaire is a brief, self-administered questionnaire composed of six "yes/no" questions for detecting fibromyalgia. The Fibromyalgia Rapid Screening Tool questionnaire has demonstrated high sensitivity and specificity among patients with chronic diffuse pain conditions. This study assessed the validity and reliability of the aforementioned questionnaire for detecting fibromyalgia among patients with chronic daily headache. ⋯ The Fibromyalgia Rapid Screening Tool is a valid and reliable instrument for identifying fibromyalgia among patients with chronic daily headache.

To elucidate perspectives on opioids and opioid use from hospitalized veterans with comorbid chronic pain using qualitative methods. ⋯ Although participants were not specifically questioned about opioid medications, discussion of opioids was prevalent in discussions of chronic pain. Findings suggest the potential utility of engaging hospitalized veterans in conversations about opioids and alternative pain management strategies.

The goal of this study was to conduct initial psychometric analyses of a seven-item pain intensity measure for persons with dementia (PIMD) that was developed using items from existing pain observational measures. ⋯ Initial evaluation of the PIMD supports its validity and reliability. Additional testing is needed to evaluate the tool's sensitivity to changes in pain intensity.
