In recent years, many extrapedicular puncture methods have been applied to percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fractures (OVCFs). However, these techniques were generally complex and had the risk of some puncture-related complications, which greatly limited the wide applications in PKP. Finding a safer and more feasible extrapedicular puncture method was rather important. ⋯ Modified unilateral extrapedicular PKP, in which the puncture trajectory was advanced through the bottom of Kambin's triangle to or across the midline of VB for proper bilateral cement distribution, greatly alleviated back pain and restored the morphology of fractured vertebrae. It seemed to be a safe and effective alternative applied to treat lumbar OVCFs with appropriate patient selection.

Although several studies have examined the epidemiological features of vertebral compression fractures (VCF) among elderly patients, few studies have reported the epidemiology of VCF among younger individuals. ⋯ The mortality rate ratio and hazard ratio were significantly higher among younger patients with VCF, indicating the need for further research on VCF in younger age groups.

Trigeminal neuralgia (TN) is the most common excruciating cranial neuralgia in the elderly population. Radiofrequency thermocoagulation (RFT) of the trigeminal ganglion is an alternative treatment for medically intractable patients with TN. RFT cannula tip position is an important issue since it is related to treatment outcome and patient safety. ⋯ Nearly 70% of patients in V2 TN and all patients in V3 TN, the cannula tip was positioned below the clival line. RFT of the trigeminal ganglion showed a successful treatment outcome with BNI I or II in 83% of patients.

The erector spinae plane block (ESPB) is a less invasive, safer, and technically easier procedure compared to the conventional neuraxial technique. Although the ESPB is a favored and easy technique compared to neuraxial block, there is no study with a large number of patients describing the exact spread level of injected local anesthetics. ⋯ The ESPB 20 mL group showed a more extensive distribution of contrast medium than that of the ESPB 10 mL group. Inadvertent injections into the epidural space, psoas muscle, and intravascular system were observed. Among them, intravascular system injections were found to be the most common (12.9%).

Clinically, neuropathic pain is a severe side effect of oxaliplatin chemotherapy, which usually leads to dose reduction or cessation of treatment. Due to the unawareness of detailed mechanisms of oxaliplatin-induced neuropathic pain, it is difficult to develop an effective therapy and limits its clinical use. ⋯ These findings suggest that reduction of SIRT1-mediated epigenetic upregulation of Nav1.7 in the DRG contributes to the development of oxaliplatin-induced neuropathic pain in rats. The intrathecal drug delivery treatment of activating SIRT1 might be a novel therapeutic option for oxaliplatin-induced neuropathic pain.
