Observational Study
Cervical Interlaminar Epidural Injections at High Doses Do Not Increase Optic Nerve Sheath Diameter on a Long-Term Basis.
Cervical epidural injection (CEI) is widely performed on patients with pain originating from the cervical spine. Studies have shown a good relationship between the optic nerve sheath diameter (ONSD) and the intracranial pressure (ICP). ⋯ Registered in the Clinical Research Information Service of the Korea National Institute of Health, registration number: KCT0001487. Key words: Analgesic techniques, epidural block, intracranial pressure, optic nerve sheath diameter, ultrasonography Analgesic techniques, epidural block, intracranial pressure, optic nerve sheath diameter, ultrasonography.

Review Meta Analysis
Can Unilateral Kyphoplasty Replace Bilateral Kyphoplasty in Treatment of Osteoporotic Vertebral Compression Fractures? A Systematic Review and Meta-analysis.
Kyphoplasty has been proven to be an efficient method to relieve patient suffering from osteoporotic vertebral compression fractures (OVCFs). Because of its technological superiority, unilateral kyphoplasty consumes less operative time and bone cement than traditional bilateral kyphoplasty. However, there is controversy about which method is most efficient in the treatment of OVCFs. Thus, an overall analysis should be performed to shed light on the facts corroborating both procedures. ⋯ Both unilateral kyphoplasty and bilateral kyphoplasty are safe and effective treatments for OVCFs. However, when operative time, cement volume, cement leakage, short-term general health, radiation dose, and hospitalization costs are taken into consideration, unilateral kyphoplasty may be the better choice. Yet, more high-quality RCTs with long-term follow-up are still required to make the final conclusion.Key words: Kyphoplasty, unilateral approach, bilateral approach, osteoporotic vertebral compression fractures, meta-analysis.

Herniated lumbar discs can induce sciatica by mechanical compression and/or chemical irritation. It was recently reported that neuroglial cellular activity after pulsed radiofrequency (PRF) application to a single dorsal root ganglion (DRG) attenuated neuroglial activity at the corresponding spinal dorsal horn. Recently, caudal epidural PRF has been used to manage neuropathic pain, but evidence of molecular changes after the administration of caudal epidural PRF to attenuate neuropathic pain is lacking, and it has not been determined whether caudal epidural PRF affects neuroglial activity at different spinal levels. ⋯ Caudal epidural PRF reduced mechanical allodynia and downregulated microglia activity and CGRP expression at the lumbar disc herniated level and in adjacent lumbar spinal levels in a rat model of lumbar disc herniation.Key words: Caudal, pulsed radiofrequency, multisegmental, lumbar disc herniation, microglia, calcitonin gene-related peptide.

Lumbar facet joint syndrome is currently suggested to be a main source of axial low back pain, and a large portion of axial low back pain is caused by disorders in lumbar facet joints. Intra-articular injection is one of the most common treatment methods in the early clinical application. Therefore, we attempt to seek a new injectable material, autologous platelet rich plasma (PRP), to treat lumbar facet syndrome, as well as to assess its therapeutic effectiveness and safety. ⋯ In the short-term period of 3 months, the new technique of lumbar facet joint injection with autologous PRP is effective and safe for patients with lumbar facet joint syndrome. Key words: Low back pain, lumbar facet joint syndrome, autologous platelet rich plasma, intra-articular injection.

Review Meta Analysis
Polyunsaturated Fatty Acids and Chronic Pain: A Systematic Review and Meta-analysis.
Chronic pain is one of the most frequent disease symptoms and represents a global health problem with a considerable economic burden. The role of polyunsaturated fatty acids (PUFA) in chronic pain conditions was debated during the last decade with conflicting results. ⋯ Our results suggest that Ω-3 PUFA supplementation moderately improves chronic pain, mainly that due to dysmenorrhea. Further investigation on the preventive potential of PUFA supplementation is needed, as the amount of evidence is scarce. Key words: Meta-analysis, systematic review, chronic pain, PUFA, supplementation, Ω-3, dysmenorrhea.
