The Effect of Intradiscal Platelet-Rich Plasma Injection for Management of Discogenic Lower Back Pain: A Meta-Analysis.
Although several researches of animal and human subjects have yielded promising results regarding intradiscal injection of platelet-rich plasma (PRP) for the management of intervertebral disc (IVD) pathologies, small sample sizes and unstandardized graft preparation procedures hampered these research efforts. Therefore, we conducted a meta-analysis to evaluate the effectiveness of intradiscal PRP injection for the treatment of discogenic lower back pain. ⋯ Intradiscal PRP injections are effective in relieving pain and improving disabilities caused by discogenic lower back pain. However, the pain-reducing effect significantly manifests two or six months after the injections, but not after one month.

Case Reports Clinical TrialUltrasound-Guided Thoracic Paravertebral Block Enhances the Quality of Recovery After Modified Radical Mastectomy: A Randomized Controlled Trial.
Ultrasound-guided thoracic paravertebral block (TPVB) has become increasingly popular for postoperative analgesia after breast surgery. We designed this prospective, randomized, double-blind, placebo-controlled trial to test the hypothesis that TPVB is superior to placebo in improving the patient quality of recovery following modified radical mastectomy. ⋯ A single preoperative injection of TPVB with ropivacaine enhances the quality of recovery and postoperative analgesia in patients following modified radical mastectomy.

Comparison of the Psychometric Properties of the FLACC Scale, the MBPS and the Observer Applied Visual Analogue Scale Used to Assess Procedural Pain.
The purpose of this study was to compare the psychometric data and feasibility and clinical utility of the Face Legs, Activity, Cry and Consolability scale (FLACC), the Modified Behavioral Pain Scale (MBPS) and the Visual Analogue Scale for observers (VASobs) used to assess procedural pain in infants and young children. ⋯ The reliability and sensitivity of the FLACC and MBPS were supported by study data but concerns about the capacity of these scales to distinguish between pain- and non-pain-related distress were raised. The VASobs cannot be recommended. Despite its limitations, the FLACC scale may be better suited than other scales for procedural pain measurement.

ReviewDevelopments in Minimally Invasive Surgical Options for Vertebral Pain: Basivertebral Nerve Ablation - A Narrative Review.
Historically, intervertebral disc degeneration has been the etiological target of chronic low back pain; however, disc degeneration is not necessarily directly associated with pain, and many other anatomical structures are potential etiologies. The vertebral endplates have been postulated to be a source of vertebral pain, where these endplates become particularly susceptible to increased expression of nociceptors and inflammatory proliferation carried by the basivertebral nerve (BVN), expressed on diagnostic imaging as Modic changes. This is useful diagnostic information that can help physicians to phenotype a subset of low back pain, which is known as vertebral pain, in order to directly target interventions, such as BVN ablation, to this significant pain generator. ⋯ Our review concluded that there is a highly clinical and statistically significant treatment effect of BVN ablation for vertebral pain with clinically meaningful benefits in pain reduction, functional improvements, opioid dose reduction, and improved quality of life. There were no reported device-related patient deaths or serious AEs based on the available literature. BVN ablation is a safe, well-tolerated and clinically beneficial intervention for vertebral pain, when proper patient selection and surgical/procedural techniques are applied.

Spreading of Pain in Patients with Chronic Pain is Related to Pain Duration and Clinical Presentation and Weakly Associated with Outcomes of Interdisciplinary Pain Rehabilitation: A Cohort Study from the Swedish Quality Registry for Pain Rehabilitation (SQRP).
The extent to which pain is distributed across the body (spreading of pain) differs largely among patients with chronic pain conditions and widespread pain has been linked to poor quality of life and work disability. A longer duration of pain is expected to be associated with more widespread pain, but studies are surprisingly scarce. Whether spreading of pain is associated with clinical presentation and treatment outcome in patients seen in interdisciplinary multimodal pain rehabilitation programs (IMMRPs) is unclear. The association between spreading of pain and (1) pain duration (2) clinical presentation (eg, pain intensity, pain-related cognitions, psychological distress, activity/participation aspects and quality of life) and (3) treatment outcome were examined. ⋯ Spreading of pain is an indicator of the duration and severity of chronic pain and to a limited extent to outcomes of IMMRP. Longer pain duration in those with more widespread pain supports the concept of early intervention as clinically important and implies a need to develop and improve rehabilitation for patients with chronic widespread pain.
