Electroencephalography During Nociceptive Stimulation in Chronic Pain Patients: A Systematic Review.
With its high temporal resolution, electroencephalography (EEG), a technique that records electrical activity of cortical neuronal cells, is a potentially suitable technique to investigate human somatosensory processing. By using EEG, the processing of (nociceptive) stimuli can be investigated, along with the functionality of the nociceptive pathway. Therefore, it can be applied in chronic pain patients to objectify whether changes have occurred in nociceptive processing. Typically, so-called event-related potential (ERP) recordings are used, where EEG signals are recorded in response to specific stimuli and characterized by latency and amplitude. ⋯ Differences in ERPs with healthy controls can mostly be found in chronic pain populations that suffer from neuropathic pain or where fiber dysfunction is present. In chronic pain populations with other etiological mechanisms, limited differences were found or agreed upon across studies.

Randomized Controlled Trial
Intravenous Paracetamol vs Intranasal Desmopressin for Renal Colic in the Emergency Department: A Randomized Clinical Trial.
To evaluate the analgesic efficacy of intranasal desmopressin alone vs intravenous paracetamol in patients referred to the emergency department with renal colic. ⋯ Our study showed that intranasal desmopressin is as effective as intravenous paracetamol for renal colic pain management; however, significant clinical reduction in pain score occurred faster with intranasal desmopressin.

To investigate the relationship of emotion regulation strategies (i.e., emotional suppression and reappraisal) with pain catastrophizing, fear of pain, pain intensity, worry, and depression as function of age in samples of older and younger adults. ⋯ Our results indicate that reappraisal strategies are important for older and younger adults with chronic pain, pointing to the necessity of considering these strategies when working clinically with such populations. However, given our findings as well as those in the literature, gender should also be considered.

Meta Analysis
Effectiveness of Invasive Techniques in Patients with Fibromyalgia: Systematic Review and Meta-Analysis.
To attain a synthesis of the evidence on the effectiveness of invasive techniques in patients with fibromyalgia, through systematic review and meta-analysis and by assessing the methodological quality of the studies considered. ⋯ Invasive techniques are considered effective for pain relief, as well as for producing a short-term increase in the pain pressure threshold, an improvement in quality of life, and a decrease in the impact of fibromyalgia.
