Project description:Arteriovenous fistula puncture pain is a serious problem for patients undergoing dialysis and a good indication for topical anesthetics. No previous study has compared lidocaine/prilocaine cream (EMLA) with lidocaine tape for pain relief during arteriovenous fistula puncture in patients undergoing maintenance hemodialysis. To this end, we conducted a multicenter randomized crossover study including 66 patients (mean age, 65.8 years; males, 57.6%) undergoing maintenance hemodialysis thrice/week. Subjects were assigned to Sequence EL (EMLA administration followed by lidocaine, with 1-week wash-out) or Sequence LE (reverse administration, first lidocaine then EMLA). All subjects completed the study. At each puncture site, 1 g EMLA (25 mg lidocaine + 25 mg prilocaine) or one sheet of lidocaine tape (18 mg lidocaine) was applied 1 h or 30 min prior to arteriovenous fistula puncture, respectively. The primary endpoint was puncture pain relief, which was measured using a 100-mm visual analog scale. The secondary endpoints included quality of life, which was measured by SF-36, and safety. EMLA produced a 10.1-mm greater visual analog scale improvement than lidocaine tape (P = 0.00001). However, there was no statistically significant difference in the quality of life between the two groups, and no significant carryover/period effect was observed in any analysis. Further, no drug-related adverse events were observed. Taken together, these results suggest that EMLA cream is superior to lidocaine tape for the relief of arteriovenous fistula puncture pain in patients undergoing maintenance hemodialysis.

Project description:ObjectivesAtraumatic needles are known to reduce complication rates of blind lumbar punctures (LP), however, their use in fluoroscopically guided LP is less studied. This study assessed the comparative difficulty of performing fluoroscopic lumbar puncture with atraumatic needles.MethodsSingle-centre retrospective case-control study comparing atraumatic and conventional or "cutting" needles using fluoroscopic time and radiation dose (Dose Area Product or DAP) as surrogate markers. Patients were assessed from two comparable eight-month periods before and after a policy change to primary use of atraumatic needles.Results105 procedures with a cutting needle were performed in the group prior to the policy change. Median fluoroscopy time was 48 sec and median DAP was 3.14. Of 102 procedures performed in the group after the policy change, 99 were performed with an atraumatic needle and three with a cutting needle after initial attempt with an atraumatic needle. Median fluoroscopy time was 41 sec and median DAP was 3.28. The mean number of attempts was 1.02 in the cutting needle group and 1.05 in the atraumatic needle group. There was no significant difference in median fluoroscopy time, median DAP, or mean number of attempts.ConclusionFluoroscopic screening time, DAP and mean number of attempts were not significantly increased with primary use of atraumatic needles for LP. Use of atraumatic needles should be considered in fluoroscopic LP given the lower complication rates.Advances in knowledgeThis study provides new data showing that the use of atraumatic needles does not increase the difficulty of fluoroscopically guided LP.

Project description:ObjectiveLumbar Puncture (LP) is a common invasive procedure where cerebrospinal fluid is obtained for the diagnosis of neurological anomalies. The purpose of this study was to evaluate the results of CSF analysis in patients admitted to pediatric wards.MethodsIn this retrospective descriptive study, records of the pediatric patients (aged <18 years) who were referred to our centers for lumbar puncture were evaluated. A checklist was prepared for all the patients where demographic data, findings of CSF and blood analysis and clinical presentations were recorded. The data obtained was analyzed using SPSSv22.ResultsIn this study a total number of 247 patients were included where 57.9% of the cases were of boys. 55.8% patients aged under 1 year and 62.3% of patients had a body temperature of 38 °C and above. 15.3% of the children were diagnosed with meningitis, 27.1% had febrile seizures, 9.3% had neonatal sepsis and for 48.2% cases other clinical diagnoses were made. There was a significant relationship between the diagnosis and the number of WBCs seen in CSF (P < 0.001). Also, there was a significant relationship between the diagnosis and amount of protein (P < 0.001) and glucose in CSF (P = 0.005). The age group and the type of fever and seizure were also significantly correlated, (P < 0.001).ConclusionLumbar puncture is an important procedure for the diagnosis of several neurological diseases. Further studies including neuroimaging and therapeutic measures are recommended in this regard.

Project description:IntroductionLumbar puncture is an important medical procedure for various diagnostics and therapies, but it can be hazardous due to individual variances in subcutaneous soft tissue, especially in the elderly and obese. Our research describes a novel robot-assisted puncture system that automatically controls and maintains the probe at the target tissue layer through a process of tissue recognition.MethodsThe system comprises a robotic system and a master computer. The robotic system is constructed based on a probe consisting of a pair of concentric electrodes. From the probe, impedance spectroscopy measures bio-impedance signals and transforms them into spectra that are communicated to the master computer. The master computer uses a Bayesian neural network to classify the bio-impedance spectra as corresponding to different soft tissues. By feeding the bio-impedance spectra of unknown tissues into the Bayesian neural network, we can determine their categories. Based on the recognition results, the master computer controls the motion of the robotic system.ResultsThe proposed system is demonstrated on a realistic phantom made of ex vivo tissues to simulate the spinal environment. The findings indicate that the technology has the potential to increase the precision and security of lumbar punctures and associated procedures.DiscussionIn addition to lumbar puncture, the robotic system is suitable for related puncture operations such as discography, radiofrequency ablation, facet joint injection, and epidural steroid injection, as long as the required tissue recognition features are available. These operations can only be carried out once the puncture needle and additional instruments reach the target tissue layer, despite their ensuing processes being distinct.

Project description:OBJECTIVE:To compare the ease of use of atraumatic needles with standard needles for diagnostic lumbar puncture and the incidence of headache after their use. DESIGN:Double blind, randomised controlled trial. SETTING:Investigation ward of a neurology unit in a university hospital. PARTICIPANTS:116 patients requiring elective diagnostic lumbar puncture. INTERVENTIONS:Standardised protocol for lumbar puncture with 20 gauge atraumatic or standard needles. OUTCOME MEASURES:The primary end point was intention to treat analysis of incidence of moderate to severe headache, assessed at one week by telephone interview. Secondary end points were incidence of headache at one week analysed by needle type, ease of use by operator according to a visual analogue scale, incidence of backache, and failure rate of puncture. RESULTS:Valid outcome data were available for 97 of 101 patients randomised. Baseline characteristics were matched except for higher body mass index in the standard needle group. By an intention to treat analysis the absolute risk of moderate to severe headache with atraumatic needles was reduced by 26% (95% confidence interval 6% to 45%) compared with standard needles, but there was a non-significantly greater absolute risk of multiple attempts at lumbar puncture (14%, -4% to 32%). Higher body mass index was associated with an increased failure rate with atraumatic needles, but the reduced incidence of headache was maintained. The need for medical interventions was reduced by 20% (1% to 40%). CONCLUSIONS:Atraumatic needles significantly reduced the incidence of moderate to severe headache and the need for medical interventions after diagnostic lumbar punctures, but they were associated with a higher failure rate than standard needles.

Project description:BackgroundAn experimental study was performed to improve the anterior approach model of intervertebral disc degeneration (IVDD).ObjectiveThe aims of this study were to investigate the anterior approach model of IVDD for the cause of death, phenotypes, and underlying mechanisms of low back pain in mice.MethodIn this study, we conducted an anterior puncture procedure on a cohort of 300 C57BL/6J mice that were 8 weeks old. Our investigation focused on exploring the causes of death in the study population (n = 300) and assessing the time-course changes in various parameters, including radiographical, histological, immunofluorescence, and immunohistochemistry analyses (n = 10). Additionally, we conducted behavioral assessments on a subset of the animals (n = 30).ResultsTransverse vertebral artery rupture is a major factor in surgical death. Radiographical analyses showed that the hydration of the nucleus pulposus began to decrease at 2 weeks after puncture and obviously disappeared over 4 weeks. 3D-CT showed that disc height was significantly decreased at 4 weeks. Osteophyte at the anterior vertebral rims was observed at 2 weeks after the puncture. As the time course increased, histological analyses showed progressive disruption of the destruction of the extracellular matrix and increased secretion of inflammatory cytokines and apoptosis. Behavioral signs of low back pain were increased between the puncture and sham groups at 4 weeks.ConclusionThe improvement of anterior intervertebral disc approach model in mice will be useful to investigate underlying mechanisms and potential therapeutic strategies for behavior and phenotypes. Furthermore, the application of vibrational pre-treatment can be used to increase the sensitivity of axial back pain in the model, thereby providing researchers with a reliable method for measuring this critical phenotype.

Project description:Lumbar puncture (LP) is an attractive route to deliver drugs to the nervous system because it is a safe bedside procedure. Its use for gene therapy has been complicated by poor vector performance and failure to target neurons. Here we report highly effective gene transfer to the primary sensory neurons of the dorsal root ganglia (DRGs) with self-complementary recombinant adeno-associated virus serotype 8 (sc-rAAV8) modeling an LP. Transgene expression was selective for these neurons outlining their cell bodies in the DRGs and their axons projecting into the spinal cord. Immunohistochemical studies demonstrated transduction of cells positive for the nociceptive neuron marker vanilloid receptor subtype 1, the small peptidergic neuron markers substance P and calcitonin gene-related peptide, and the nonpeptidergic neuron marker griffonia simplicifolia isolectin B4. We tested the efficacy of the approach in a rat model of chronic neuropathic pain. A single administration of sc-rAAV8 expressing the analgesic gene prepro-beta-endorphin (ppbetaEP) led to significant (P < 0.0001) reversal of mechanical allodynia for >/=3 months. The antiallodynic effect could be reversed by the mu-opioid antagonist naloxone 4 months after gene transfer (P < 0.001). Testing of an alternative nonopioid analgesic gene, IL-10, alone or in combination with ppbetaEP was equally effective (P < 0.0001). All aspects of the procedure, such as the use of an atraumatic injection technique, isotonic diluent, a low-infusion pressure, and a small injection volume, are consistent with clinical practice of intrathecal drug use. Therefore, gene transfer by LP may be suitable for developing gene therapy-based treatments for chronic pain.

Project description:UnlabelledIn this large, sham-controlled, randomized trial, we examined the efficacy of the combination of standard treatment and paraspinous lidocaine injection compared with standard therapy alone in subjects with chronic low back pain. There is little research-based evidence for the routine clinical use of paraspinous lidocaine injection for low back pain. A total of 378 subjects with nonspecific chronic low back pain were randomized to 3 groups: paraspinous lidocaine injection, analgesics, and exercises (group 1, LID-INJ); sham paraspinous lidocaine injection, analgesics, and exercises (group 2, SH-INJ); and analgesics and exercises (group 3, STD-TTR). A blinded rater assessed the study outcomes at 3 time points: baseline, after treatment, and after 3 months of follow-up. There were increased frequency of pain responses and better low back functional scores in the LID-INJ group compared with the SH-INJ and STD-TTR groups. These effects remained at the 3-month follow-up but differed between all 3 groups. There were significant changes in pain threshold immediately after treatment, supporting the effects of this intervention in reducing central sensitization. Paraspinous lidocaine injection therapy is not associated with a higher risk of adverse effects compared with conventional treatment and sham injection. Its effects on hyperalgesia might correlate with changes in central sensitization.Clinical trial registrationNCT02387567.PerspectiveThere are few data to support paraspinous lidocaine injection use in patients with nonspecific chronic low back pain. Our results show that this therapy when combined with standard therapy significantly increases the number of responders versus standard treatment alone. Its effects on hyperalgesia might correlate with a change in central sensitization.

Project description:BackgroundWe aimed to investigate the effect of transforaminal injection of Magnesium sulphate versus Ozone on pain intensity, functional disability and the oxidative stress biomarkers; superoxide dismutase (SOD) and Glutathione (GSH) in patients with lumbar disc prolapse.MethodsThis randomized controlled trial was conducted on 135 patients having symptomatic lumbar disc prolapse, received either transforaminal injection of Magnesium sulphate with steroids, Ozone with steroids, or steroids alone. Assessment of pain severity and functional disability were done before intervention, 2 weeks, 1, 3, and 6 months after intervention. Serum SOD and GSH were measured for all included patients before and 2 weeks after intervention.ResultsThere was a statistically significant improvement in pain intensity and functional disability 2 weeks after intervention in the three groups, but at 1-month and 3-months after intervention, the significant improvement was in Mg sulphate and Ozone groups only. At 6-months follow up, Mg sulphate group only showed a significant improvement. There was a statistically significant increase in SOD and GSH serum levels, 2-weeks after intervention in both Magnesium sulphate (P-value = 0.002, 0.005 respectively) and ozone groups (P-value < 0.001, < 0.001), but there was no statistically significant change in SOD and GSH serum levels in control group.ConclusionTransforaminal injection of Mg sulphate in patients with lumbar disc prolapse causes significant long-term improvement (up to 6 months) in pain intensity and functional disability. The serum levels of SOD and GSH were significantly increased at 2 weeks following both transforaminal injection of Mg sulphate and ozone.
