The Neurostimulation Appropriateness Consensus Committee (NACC): Recommendations on Best Practices for Cervical Neurostimulation.

INTRODUCTION: The International Neuromodulation Society convened a multispecialty group of physicians based on expertise with international representation to establish evidence-based guidance on the use of neurostimulation in the cervical region to improve outcomes. This Neurostimulation Appropriateness Consensus Committee (NACC) project intends to provide evidence-based guidance for an often-overlooked area of neurostimulation practice. MATERIALS AND METHODS: Authors were chosen based upon their clinical expertise, familiarity with the peer-reviewed literature, research productivity, and contributions to the neuromodulation literature. Section leaders supervised literature searches of MEDLINE, BioMed Central, Current Contents Connect, Embase, International Pharmaceutical Abstracts, Web of Science, Google Scholar, and PubMed from 2017 (when NACC last published guidelines) to the present. Identified studies were graded using the US Preventive Services Task Force criteria for evidence and certainty of net benefit. Recommendations are based on the strength of evidence or consensus when evidence was scant. RESULTS: The NACC examined the published literature and established evidence- and consensus-based recommendations to guide best practices. Additional guidance will occur as new evidence is developed in future iterations of this process. CONCLUSIONS: The NACC recommends best practices regarding the use of cervical neuromodulation to improve safety and efficacy. The evidence- and consensus-based recommendations should be utilized as a guide to assist decision making when clinically appropriate.

Cannabis for Pain and Headaches: Primer.

PURPOSE OF REVIEW: Marijuana has been used both medicinally and recreationally since ancient times and interest in its compounds for pain relief has increased in recent years. The identification of our own intrinsic, endocannabinoid system has laid the foundation for further research. RECENT FINDINGS: Synthetic cannabinoids are being developed and synthesized from the marijuana plant such as dronabinol and nabilone. The US Food and Drug Administration approved the use of dronabinol and nabilone for chemotherapy-associated nausea and vomiting and HIV (Human Immunodeficiency Virus) wasting. Nabiximols is a cannabis extract that is approved for the treatment of spasticity and intractable pain in Canada and the UK. Further clinical trials are studying the effect of marijuana extracts for seizure disorders. Phytocannabinoids have been identified as key compounds involved in analgesia and anti-inflammatory effects. Other compounds found in cannabis such as flavonoids and terpenes are also being investigated as to their individual or synergistic effects. This article will review relevant literature regarding medical use of marijuana and cannabinoid pharmaceuticals with an emphasis on pain and headaches.

Interventional cancer pain therapies.

Interventional pain therapies play a critical role in palliation of severe cancer pain. Anesthesiologists specializing in cancer pain management have developed minimally invasive techniques to: (1) optimize pain control; (2) minimize side effects, adverse outcomes, and costs; (3) enhance functional abilities and physical and psychological well-being; and (4) enhance the quality of life for cancer patients. A thorough understanding of the pathophysiology of the cancer pain is needed to implement interventional therapies. It is also important to understand the prognosis of the patient, associated comorbidities, and expectations of the patient and family. Interventional pain therapies are minimally invasive techniques that can be divided into direct drug delivery, neuroablation and neural blockade, and neurostimulation.

Role of injection therapy: review of indications for trigger point injections, regional blocks, facet joint injections, and intra-articular injections.

Injection therapies play a major role in the management of various pain conditions. Some injections are relatively simple to perform whereas others are technically demanding with significant risk of mortality and morbidity. Traditional therapies such as intra-articular injections, regional blocks, and trigger-point injections continue to be redefined as we gain a better understanding into the pathophysiology of nociception, with a greater insight into regional anatomy using improved imaging capabilities. Injection therapies are becoming an integral part of the multidisciplinary therapies required to improve and rehabilitate pain patients. The necessity of clinical outcome assessments including functional-based outcomes and cost-effective analysis is becoming more important in the current medical reimbursement environment.
