BACKGROUND: The high risk of developing postherpetic neuralgia (PHN) is associated with severe immunosuppressive diseases. A malignancy itself, as well as surgery, radiotherapy, and other treatments, can lead to changes in the immune status of the body and predispose patients with a malignancy to PHN. OBJECTIVE: To investigate the risk factors of postherpetic neuralgia in herpes zoster (HZ) after a malignant tumor and to provide better preventive strategies for clinical practice...

BACKGROUND: Despite the advantages of ultrasound and previous anatomical data on neuromuscular junction locations, to the best of our knowledge, the feasibility and accuracy of precise ultrasound-guided injection techniques into the proposed injection site of botulinum neurotoxin for the levator scapulae muscle have not been assessed in any publication. OBJECTIVE: In the present cadaver-based study, the ultrasound-guided injection technique in the middle and distal portions of the levator scapulae muscle was evaluated to determine whether this method distributes injections properly to the target muscle in fresh cadavers...

BACKGROUND: Anesthetic spread of ultrasound-guided paraspinal blocks is still unknown. OBJECTIVES: To compare the drug diffusion qualities of intertransverse process block (ITPB) and erector spinae plane block (ESPB) in clinical practice. STUDY DESIGN: Prospective computed tomography (CT)-3-dimensional (3D) reconstruction image study. SETTING: Operation room in hospital. METHODS: Twenty patients undergoing thoracoscopic pulmonary wedge resection or segmentectomy were enrolled...

BACKGROUND: Whiplash trauma can result in a range of symptoms, including chronic neck pain, headache, facial pain, upper back pain, and tinnitus, which comprises whiplash-associated disorder (WAD). Intermediate cervical plexus block (iCPB) is a novel intervention that targets the upper cervical nerves and anecdotal reports suggest benefits in WAD. OBJECTIVES: We hypothesized that the cervical plexus may have a role in the pathogenesis of WAD and blocking the cervical plexus may provide analgesia...

BACKGROUND: Neuropathic mechanisms largely contribute to radicular Low Back Pain (LBP) and an increase in oxidative stress is recognized as one of the possible causes of nerve damage, inducing axonal degeneration and myelin degradation of nerve fibers. OBJECTIVES: We investigated whether a combination of nutraceutical supplements and oxygen-ozone (O2-O3) therapy might reduce disability and improve clinical effects of pharmacological therapy in patients with acute radicular LBP...

BACKGROUND: Chronic cervical facet joint pain is a leading cause of pain and disability. In patients nonresponsive to conservative treatment, cervical facet radiofrequency ablation (RFA) has shown to be efficacious. However, the conventional RFA technique can be cumbersome. A novel RFA technique with a multitined cannula allows for a lateral approach and represents an attractive alternative option for cervical facet RFA. It offers a potentially shorter, less cumbersome procedure, with consequently less x-ray exposure and patient discomfort than the conventional cervical RFA...

BACKGROUND: Computed tomography-guided percutaneous selective radiofrequency thermocoagulation (RFT) of the trigeminal nerve is a novel, minimally invasive technique for the treatment of trigeminal neuralgia, but the high recurrence rate after surgery might pose a serious problem. OBJECTIVES: The purpose of this study was to explore the risk factors affecting the recurrence rate after RFT and to predict the recurrence rate and provide evidence for the early prediction...

BACKGROUND: There continues to be significant reliance on pharmacological modalities for the management of chronic pain, with a particular focus on opioid analgesics as a singular option for pain management. Fibromyalgia is a prototypical central pain disorder, which is often used as a model to study chronic pain disorders. It has an estimated prevalence of approximately 1.1% to 5.4% in the general population. The widespread use of opioids in patients with fibromyalgia has been well demonstrated in several health claims database studies, with rates of use ranging from 11...

BACKGROUND: Upper lateral hip pain is a common complaint in adults and is referred to as greater trochanteric pain syndrome (GTPS) and is more prevalent among older women. This is a debilitating condition that could result in lower physical activity and quality of life, and higher unemployment rate. GTPS is a clinical diagnosis, and many cases improve with conservative medical management (CMM). However, there is still a gap between patients not responding to CMM and those who are not good surgical candidates...

BACKGROUND: Subdural hematoma (SDH) is a potentially life-threatening complication in patients with spontaneous intracranial hypotension (SIH). Though bed rest is the basis of conservative treatment, no clear evidence exists regarding the association between bed rest and the later complication of SDH in these patients. OBJECTIVES: This study aimed to evaluate the association between bed rest and SDH development in patients with SIH. STUDY DESIGN: A retrospective study was conducted from March 2013 through December 2019...

BACKGROUND: Intrathecal analgesia (ITA) is a valuable treatment option for refractory cancer-related pain. However, there is still no general consensus on the analgesic effect of movement-evoked breakthrough pain (MEBTP) in the ITA setting. OBJECTIVES: This study aimed to conduct a retrospective observational study to examine the effect of ITA via percutaneous port (ITAPP) with patient-controlled ITA (PCIA) on analgesic efficacy, emphasizing MEBTP in patients with refractory lower extremity cancer pain...

BACKGROUND: There is a global shortage of iohexol contrast media, commonly used in epidural injections, as a result of lockdown and decreased production due to COVID-19. Iohexol bottles are designated for single use, which, depending on the vials available, often leads to wasting up to 95% of this limited resource. However, avoiding multiple withdrawals may be unnecessary if withdrawing multiple times using sterile technique does not increase the risk for contamination. OBJECTIVES: The purpose of our study is to determine whether multiple withdrawals from iohexol injection bottles using a sterile technique poses a greater risk of introducing contaminants than a single withdrawal...

BACKGROUND: A diseased shoulder due to pain, stiffness, or weakness negatively affects patients' quality of life and their ability to carry out activities of daily living. Adhesive capsulitis is a disease characterized by shoulder pain and global limitation of movement in the shoulder joint. Many interventions have been proposed for the treatment of primary adhesive capsulitis. The current study compares the effect of ultrasound-guided intraarticular injection of ozone versus steroid versus intraarticular application of pulsed radiofrequency...

BACKGROUND: Postoperative pain after hip arthroscopy remains a major cause of patient dissatisfaction in the immediate postoperative period. Adequate postoperative analgesia is associated with increased patient satisfaction, earlier mobilization, and decreased opioid consumption. OBJECTIVES: Therefore, there is a need for safe, reliable, and opioid- and motor-sparing methods of achieving postoperative analgesia following hip arthroscopy. We evaluated the efficacy of pericapsular nerve group (PENG) block vs fascia iliaca block (FIB) in reducing postoperative pain and analgesic consumption in the first 24 hours following hip arthroscopy...
