BACKGROUND The purpose of our study was to determine the functional role of microRNA (miR)-16 in chronic inflammatory pain and to disclose its underlying molecular mechanism. MATERIAL AND METHODS Inflammatory pain was induced by injection of complete Freund's adjuvant (CFA) to Wistar rats. The pWPXL-miR-16, PcDNA3.1- Ras-related protein (RAB23), and/or SB203580 were delivered intrathecally to the rats. Behavioral tests were detected at 0 h, 4 h, 1 d, 4 d, 7 d, and 14 d after CFA injection. After behavioral tests, L4-L6 dorsal spinal cord were obtained and the levels of miR-16, RAB23, and phosphorylation of p38 (p-p38) were evaluated by quantitative real-time PCR (qRT-PCR)...

P2X4 receptors (P2X4R) are a family of ATP-gated non-selective cation channels. We previously demonstrated that activation of P2X4R in spinal microglia is crucial for neuropathic pain, a highly debilitating chronic pain condition, suggesting that P2X4R is a potential therapeutic target for treating neuropathic pain. Thus, the identification of a compound that has a potent inhibitory effect on P2X4R is an important clinical challenge. In the present study, we screened a chemical library of clinically approved drugs and show for the first time that duloxetine, a serotonin and noradrenaline reuptake inhibitor, has an inhibitory effect on rodent and human P2X4R...

OBJECTIVE The aim of this study was to evaluate the utility of supplementing long thoracolumbar posterior instrumented fusion (posterior spinal fusion, PSF) with lateral interbody fusion (LIF) of the lumbar/thoracolumbar coronal curve apex in adult spinal deformity (ASD). METHODS Two multicenter databases were evaluated. Adults who had undergone multilevel LIF of the coronal curve apex in addition to PSF with L5-S1 interbody fusion (LS+Apex group) were matched by number of posterior levels fused with patients who had undergone PSF with L5-S1 interbody fusion without LIF (LS-Only group)...

BACKGROUND CONTEXT: Spine pain and the disability associated with it are epidemic in the United States. According to the National Center for Health Statistics, >650,000 spinal fusion surgeries are performed annually in the US and yet there is a failure rate of 15-40% when standard methods employing current commercial bone substitutes are utilized. Autologous bone graft is the gold standard in terms of fusion success, but the morbidity associated with the procedure and limitations in the availability of sufficient material has limited its use in the majority of cases...

OBJECTIVE: T-type channel (TCC) CaV3.2 plays a pivotal role in pain transmission. In this study, we examined the effects of intrathecal TCC blockers on CaV3.2 expression in a L5/6 spinal nerve ligation (SNL) pain model. The neurotoxicity of TCC blockers were also evaluated. METHODS: Male Sprague-Dawley rats (200-250 g) were used for right L5/6 SNL to induce neuropathic pain. Intrathecal infusion of saline or TCC blockers [mibefradil (0.7 μg/h) or ethosuximide (60 μg/h)] was started after surgery for 7 days...

STUDY DESIGN: This was a radiographic validity and reliability study. OBJECTIVE: We assessed the validity and reliability of measurements made on standing lateral lumbar radiographs, compared with lateral whole-spine radiographs, for evaluating spinopelvic parameters and lumbar lordosis (LL). SUMMARY OF BACKGROUND DATA: A lateral whole-spine radiograph is the gold standard image for measurement of spinopelvic parameters. However, little evidence is available on the reliability of measurements made on such radiograph...

Opioids and NSAIDs are commonly used to manage pain in the early phase of spinal cord injury (SCI). Despite its analgesic efficacy, however, our studies suggest that intrathecal (i.t.) morphine undermines locomotor recovery and increases lesion size in a rodent model of SCI. Similarly, intravenous (i.v.) morphine attenuates locomotor recovery. The current study explores whether i.v. morphine also increases lesion size after a spinal contusion (T12) injury, and quantifies the cell types that are affected by early opioid administration...

Extramammary Paget disease (EMPD) is an uncommon malignancy. It manifests either in the primary form in the skin as an intraepithelial neoplasm, or in secondary form as pagetoid (intraepithelial) spread of an underlying internal carcinoma to the skin. Although local invasion and recurrence of primary extramammary Paget disease are relatively frequent, widespread metastases are rare. As such, there are very few reports and little characterization of the radiologic features of widespread spinal metastases. To our knowledge, there are no prior reports of a metastatic extramammary Paget disease presenting as a painful pathologic vertebral body compression fracture...

Kilohertz-frequency spinal cord stimulation (KHF-SCS) is a potential paresthesia-free treatment for chronic pain. However, the effects of KHF-SCS on spinal dorsal column (DC) axons and its mechanisms of action remain unknown. The objectives of this study were to quantify activation and conduction block of DC axons by KHF-SCS across a range of kHz frequencies (1, 5, 10, or 20 kHz) and waveforms (biphasic pulses or sinusoids). Custom platinum electrodes delivered SCS to the T10/T11 DCs of anesthetized male Sprague-Dawley rats...

Toll-like receptor 4 (TLR4) is important for the pathogenesis of inflammatory reactions and the promotion of pain processing after ischemia/reperfusion (IR) in spinal cord. Recently, C-X-C chemokine ligand 12 (CXCL12) and its receptor, C-X-C chemokine receptor 4 (CXCR4), were demonstrated to be simultaneously critical for inflammatory reactions, thereby facilitating glial activation. However, whether CXCL12/CXCR4 expression can contribute to IR-induced inflammatory pain via spinal TLR4 remained unclear. A rat model was established by 8 min of aortic arch occlusion...

STUDY DESIGN: A prospective observational study. OBJECTIVE: The aim of this study was to identify the relationship between obesity, quantified by body mass index (BMI), and both back and leg pain in spinal patients. SUMMARY OF BACKGROUND DATA: Obesity and back pain are massive public health problems. Given the poor correlation between pain and a pathological change in the spine, further investigation is required into other, nonpathological predictors such as obesity...
