Radiofrequency ablation of the hip: review.

Radiofrequency ablation (RFA) of the articular branches of the femoral and obturator nerves (the innervation of the anterior capsule of the hip) is an emerging treatment for chronic hip pain. Body mass index (BMI) greater than 30, older age, large acetabular/femoral head bone marrow lesions, chronic widespread pain, depression, and female sex increase the risk of developing hip pain. Chronic hip pain is a common condition with a wide range of etiologies, including hip osteoarthritis (OA), labral tears, osteonecrosis, post total hip arthroplasty (THA), post-operative dislocation/fracture, and cancer.

New-Onset Tinnitus After Dorsal Root Ganglion Stimulator Implantation: A Case Report.

Dorsal column (dcSCS) and dorsal root ganglion stimulation (DRG-S) complications are similar, typically related to placement and device failure. We present the first case of tinnitus after DRG-S implantation. The patient presented with complex regional pain syndrome (CRPS) type 2.

Caring for Our Patients With Opioid Use Disorder in the Perioperative Period: A Guide for the Anesthesiologist.

Opioid use disorder (OUD) is a rising public health crisis, impacting millions of individuals and families worldwide. Anesthesiologists can play a key role in improving morbidity and mortality around the time of surgery by informing perioperative teams and guiding evidence-based care and access to life-saving treatment for patients with active OUD or in recovery. This article serves as an educational resource for the anesthesiologist caring for patients with OUD and is the second in a series of articles published in Anesthesia & Analgesia on the anesthetic and analgesic management of patients with substance use disorders.

Needs-based novel digital curriculum for the neuromodulation training deficit: Pain Rounds.

This study reports the needs-based development, effectiveness and feasibility of a novel, comprehensive spinal cord stimulation (SCS) digital curriculum designed for pain medicine trainees. The curriculum aims to address the documented systematic variability in SCS education and empower physicians with SCS expertise, which has been linked to utilization patterns and patient outcomes. Following a needs assessment, the authors developed a three-part SCS e-learning video curriculum with baseline and postcourse knowledge tests.

A Survey on the Choice of Spinal Cord Stimulation Parameters and Implantable Pulse Generators and on Reasons for Explantation.

Objective: Spinal Cord Stimulation (SCS) is a vital treatment for chronic intractable pain. In the last few years, the field has undergone dramatic changes in new waveform and frequency introduction as well as device miniaturization. It is important to understand contemporary practice patterns regarding these parameters.

Telemedicine and current clinical practice trends in the COVID-19 pandemic.

Telemedicine is the medical practice of caring for and treating patients remotely. With the spread of the coronavirus disease-2019 (COVID-19) pandemic, telemedicine has become increasingly prevalent. Although telemedicine was already in practice before the 2020 pandemic, the internet, smartphones, computers, and video-conferencing tools have made telemedicine easily accessible and available to almost everyone.

Presence of opioid safety initiatives, prescribing patterns for opioid and naloxone, and perceived barriers to prescribing naloxone: Cross-sectional survey results based on practice type, scope, and location.

Background And Objectives: The opioid epidemic is a public health crisis in the United States (US) and is associated with devastating consequences, including opioid misuse and related overdose. In response to the opioid crisis, the US Department of Health and Human Services is advancing improved practices in pain management. Strategies to help mitigate opioid risks include physician safety programs, hospital- or practice-based initiatives, patient education, and harm reduction campaigns that include the use of naloxone.

Substantial Elevation of Liver Enzymes During Ketamine Infusion: A Case Report.

Intravenous infusion of a subanesthetic dose of ketamine has been shown to improve neuropathic pain. However, ketamine-induced liver injury can occur. Reported here are 2 cases with substantial liver enzyme elevations less than 2 days after initiation of repeat ketamine infusion at least 7 months after the last infusion.

Spinal Cord Stimulator Placement in Patient With von Willebrand Disease: A Case Report.

Complex regional pain syndrome (CRPS) is a regional neuropathic pain syndrome. Excruciating pain often interferes with patients' ability to function normally. Spinal cord stimulators (SCS) have been effective in treating pain along with signs of sympathetic overactivity in patients with CRPS.

Sphenopalatine Ganglion Blocks in the Management of Head and Neck Cancer-Related Pain: A Case Series.

Head and neck cancer can be painful, debilitating, and refractory to oral medications. Due to the association of the sphenopalatine ganglion (SPG) with maxillary nerve sensory fibers, SPG blocks may be used to treat the pain of the hard and soft palate, tonsils, nasal cavity, paranasal sinuses, oral gingiva, premaxillary soft tissue, maxilla, and orbital floor. We present the first case series of performing SPG blocks utilizing TX360 nasal atomizers or angiocatheters to treat head and neck cancer-related pain.

Low-Dose Intrathecal Ziconotide for Spasticity From Primary Lateral Sclerosis: A Case Report.

Spasticity can be very debilitating and painful. We present a case of severe spasticity from primary lateral sclerosis refractory to intrathecal baclofen in doses up to 1100 μg/d. Baclofen was weaned down and switched to intrathecal ziconotide at 0.

Sympathetic blocks for complex regional pain syndrome: a survey of pain physicians.

Background: Sympathetic blocks (SB) are commonly used to treat pain from complex regional pain syndrome (CRPS). However, there are currently no guidelines to assist pain physicians in determining the best practices when using and performing these procedures.

Methods: A 32-question survey was developed on how SBs are used and performed to treat CRPS.

Postoperative oxycodone toxicity in a patient with chronic pain and end-stage renal disease.

We present this case to review the metabolism of oxycodone and the effects of end-stage renal disease on the elimination of oxycodone and its metabolites. A 42-year-old female with end-stage renal disease who was dependent on hemodialysis presented for left hamstring posterior capsule release. She had been receiving methadone for 2 years for chronic leg pain.
