Letter Case Reports
Ultrasound-Guided L5/S1 Intradiscal Needle Placement using Biplanar Approach with the Patient in the Lateral Decubitus Position - A Report of Three Cases.
The use of ultrasound (US)-guided intradiscal injection has been described in the literature with the patient lying in the prone position; however, many patients are unable to lie in the prone position. Therefore, we describe an innovative technique of US-guided platelet-rich plasma (PRP) administration in the lumbar intervertebral disc (IVD) of 3 patients with chronic lower back pain who failed to improve with conservative management. ⋯ This report described a novel technique demonstrating that US-guided lumbar intradiscal needle placement for PRP administration in patients lying in the lateral decubitus position is feasible.

Postoperative analgesia is widely used for patients undergoing major surgeries. Individual differences in genetic polymorphisms may be obstructive factors for accurately anesthetics using. However, the equation for predicting sufentanil dosage postoperatively based on genetic design has been established yet. Our aim was to establish sufentanil dosage postoperatively prediction equation based on patients' genetic polymorphisms. ⋯ We established the prediction equation for individual sufentanil dosage postoperatively based on gene polymorphisms. The results showed this prediction equation was valid, which might be used for different types of surgeries. We established an equation for individual dosage of sufentanil for postoperative analgesia based on gene polymorphisms. The results show that the prediction equation is valid, the information might be used for different types of postoperative analgesia, and the painful patients will have great potential safe and personalized pain control after analgesic therapy. It might also have potential as a clinical tool.

Neuropathic pain (NP) is a complex condition that impairs the patients' quality of life. Registries are useful tools, increasingly used as they provide high-quality data. This article aims to describe the Greek Neuropathic Pain Registry (Gr.NP.R.) design, the patients' baseline data, and real-world treatment outcomes. ⋯ The Gr.NP.R. provides information on the demographics, clinical progress, treatment history, treatment responses, and the drugs of choice for patients with cancer and non-cancer NP. The collected data may help physicians plan the management of their patients.

Proinflammatory mechanisms are implicated in pain states. Recent research indicates that patients with osteoarthritis (OA) with signs of central sensitization exhibit elevated cerebrospinal fluid (CSF) levels of interferon gamma-induced protein 10 (IP-10), Fms-related tyrosine kinase 1 (Flt-1), and monocyte chemoattractant protein 1 (MCP-1). ⋯ THA leads to long-term decreases in pain sensitivity, indicative of resolution of sensitization processes. Changes in CSF and plasma levels of IP-10, and plasma IL-8, may be associated with altered pain phenotype.

Complex regional pain syndrome is a painful and debilitating syndrome in which the patient presents with disabling pain, edema, and/or vasomotor or sudomotor abnormalities. The mechanism is complex and not well understood. There is no definitive treatment for the condition yet. ⋯ Conventional medications, epidural block, and sympathetic nerve block provided temporary relief. We performed pulsed radiofrequency of the saphenous nerve for the management of lower limb pain, and the symptoms remained under control at 3 months. To the best of our knowledge, this is the first application of ultrasound-guided pulsed radiofrequency of the saphenous nerve for the management of complex regional pain syndrome.
