Conditioned pain modulation (CPM) can discriminate between healthy and chronic pain patients. However, its relationship with neurophysiological pain mechanisms is poorly understood. Brain oscillations measured by electroencephalography (EEG) might help gain insight into this complex relationship.

Randomized Controlled Trial
Effect of transcranial direct current brain stimulation of the motor cortex on chemotherapy induced nausea and vomiting in female patients with breast cancer.
Chemotherapy-induced nausea and vomiting (CINV) is an adverse outcome associated with chemotherapy and is sometimes difficult to manage. This study aimed to examine the impact of a single session of transcranial direct current brain stimulation (tDCS; 2 mA) over the motor cortex for 20 minutes before chemotherapy in patients receiving a highly emetogenic chemotherapy. ⋯ A single session of M1 tDCS is suggested as an effective adjuvant therapy to control CINV in female patients suffering from breast cancer and receiving highly emetogenic chemotherapy. Corroboratory studies are needed.

Meta Analysis
Repetitive transcranial magnetic stimulation for fibromyalgia patients: A Systematic Review with Meta-Analysis.
Fibromyalgia is a poorly understood pain syndrome. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive brain stimulation therapy and is commonly applied for the management of fibromyalgia. However, controversy about its efficacy remains. Therefore, a meta-analysis was conducted to evaluate the effectiveness of rTMS for fibromyalgia syndrome. ⋯ This study demonstrated that rTMS relieved pain and enhanced the quality of life of patients with fibromyalgia; however, on the basis of current reports, it did not improve anxiety, depression, or other symptoms.

Randomized Controlled Trial
The effect of erector spinae block versus serratus plane block on pain scores and diaphragmatic excursion in multiple rib fractures. A prospective randomized trial.
We aimed to investigate whether ultrasound guided erector spinae plane block and serratus anterior plane block would provide effective and safe analgesia in patients with fracture ribs, and to detect their effects on diaphragmatic excursion in such cases. ⋯ Both erector spinae block and serratus plane block provided safe and effective pain relief in traumatic rib fractures. Although the erector spinae group displayed significantly reduced pain scores, decreased analgesic needs and improved diaphragmatic excursion as compared to serratus group, nevertheless, this was of no clinical significance.
