Randomized Controlled Trial
Ultrasound-Guided Genicular Nerve Block for Knee Osteoarthritis: A Double-Blind, Randomized Controlled Trial of Local Anesthetic Alone or in Combination with Corticosteroid.
Recently, several studies suggested that radiofrequency (RF) ablation of the genicular nerves is a safe and effective therapeutic procedure for intractable pain associated with chronic knee osteoarthritis (OA). Diagnostic genicular nerve block (GNB) with local anesthetic has been generally conducted before making decisions regarding RF ablation. Although GNB has been recently performed together with corticosteroid, the analgesic effects of corticosteroids for treating chronic pain remain controversial. ⋯ Chronic pain, knee osteoarthritis, genicular nerve block, ultrasound, corticosteroid, local anesthetic, visual analog scale, Oxford Knee Score.

Meta Analysis
Characteristics of the Middle Cervical Sympathetic Ganglion: A Systematic Review and Meta-Analysis.
Understanding the characteristics of the middle cervical sympathetic ganglion (MCSG) may minimize procedure-related complications and maximize efficacy during surgery or ultrasound (US)-guided procedures. The location and detection rate of the MCSG were variable in small population studies. Therefore, a large population study or meta-analysis could give more information about the MCSG. ⋯ Middle cervical sympathetic ganglion, cervical sympathetic trunk, cervical sympathetic chain, ultrasound, nerve block, ethanol ablation, radiofrequency ablation, thyroid, Horner syndrome, meta-analysis.

Randomized Controlled Trial
Cerebral Blood Flow and Heart Rate Variability in Chronic Fatigue Syndrome: A Randomized Cross-Over Study.
Pain, fatigue, and concentration difficulties are typical features of chronic fatigue syndrome (CFS). The exact underlying mechanisms of these symptoms are still unknown, but available evidence suggests an important role for impaired pain modulation. As evidence also suggests that pain modulation is related to cardiovascular mechanisms, it seems logical to investigate whether cerebral blood flow (CBF) and heart rate variability (HRV) are altered in these patients. ⋯ Chronic pain, physical exercise, emotional stress, pain modulation, cardiovascular systems, temporal summation, pain pressure thresholds, transcranial Doppler, plethysmography.

Clinical Trial
The Effect of Caudal Epidural Pulsed Radiofrequency Stimulation in Patients with Refractory Chronic Idiopathic Axonal Polyneuropathy.
Many patients with chronic idiopathic axonal polyneuropathy (CIAP) suffer from neuropathic pain, which is managed using several oral medications and modalities. However, despite these treatments, pain persists in some patients. ⋯ Pulsed radiofrequency, chronic idiopathic axonal neuropathy, caudal epidural stimulation, neuropathic pain chronic pain, refractory pain.

Insufficient cement distribution (ICD) in the fractured area has been advocated to be responsible for unsatisfied pain relief after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCFs). However, little is known about risk factors for the occurrence of ICD. ⋯ Percutaneous vertebroplasty, insufficient cement distribution, fractured area, risk factor, osteoporosis, vertebral compression fracture, spine, unsatisfied pain relief, cement augmentation.
