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.

Impacto de la Pandemia de COVID-19 en la Práctica de la Neuromodulación en Argentina / Impact of the COVID-19 Pandemic on the Practice of Neuromodulation in Argentina

Introducción: El objetivo de este estudio fue evaluar el impacto de la pandemia de Covid-19 en la práctica de la Neuromodulación en Argentina. Material y Métodos: Se envió una encuesta a los profesionales que practican la Neuromodulación en Argentina entre el 19 de julio al 20 de agosto de 2020. Se determinó el impacto de Covid-19 a nivel profesional y personal. Todas las variables fueron comparadas y analizadas. Resultados: Veinticuatro profesionales respondieron a la encuesta completa. La mayoría de ellos eran varones (87,5%), en el grupo de edad de 45 a 59 años (37,5%), con 15 o más años de experiencia (45,83%). Los neurocirujanos fueron la mayoría (87,5%), siendo las técnicas ablativas la práctica predominante (26,47%). La gran mayoría informó una disminución de las prácticas quirúrgicas (83,33%), entre el 50 y el 74% de ellas (40%), siendo la decisión del financiador la razón única más citada (43,47%) y la Estimulación Cerebral Profunda, la técnica quirúrgica más afectada (41,6%). El 100% de los entrevistados declaró que los pacientes habían sido perjudicados por la suspensión de cirugías y que los ingresos económicos se redujeron de alguna manera, también en el 100% de los encuestados. A nivel personal, ninguno de los profesionales reportaron haber sido diagnosticados de la enfermedad. Sin embargo, el 37,5% sufrió algún otro tipo de daño a nivel físico y el 20,83% informó secuelas psicológicas, especialmente ansiedad. Conclusión: La actual pandemia de Covid-19 ha tenido un impacto muy significativo en la práctica de la Neuromodulación en Argentina, tanto a nivel profesional como personal. Este impacto debe ser tenido en cuenta en el futuro, en caso de una nueva pandemia, para prevenir los efectos nocivos que se registraron en este estudio

Background: The objective of this study was to evaluate the impact of the Covid-19 outbreak in the practice of Neuromodulation in Argentina. Methods: A survey was sent to Argentina neuromodulation practitioners from July 19 to August 20, 2020. The impact of Covid-19 on the professional and personal level were determined. All variables were compared and analyzed. Results: Twenty-four practitioners responded to the complete survey. Most of them were male (87.5%), in the 45-59 year age group (37.5%), with 15 or more years of experience (45.83%). Neurosurgeons were in the majority (87.5%), with ablative techniques being the predominant practice (26.47%). The great majority reported a decrease in surgical practices (83.33%), between 50 and 74% of them (40%), with the decision of the financer being the most cited reason (43.47%), and Deep Brain Stimulation the most affected surgical technique (41.6%). 100% of the interviewed declared that the patients had been harmed by the suspension of surgeries, and that the economic income was reduced in some way in 100% of the interviewed. On a personal level, none of the professionals reported having been diagnosed with the disease. However, 37.5% suffered physical manifestations, and 20.83% reported psychological sequelae, especially anxiety. Conclusion: The current Covid-19 pandemic yielded a significant impact on the daily work practice as well as on the personal level of practitioners in neuromodulation in Argentina. This impact must be taken into account in the long term to avoid further harmful effects and their sequels and to take appropriate preventive measures in the event of another pandemic

Successful Unilateral Surgical Approach to Internal Globus Pallidus and Ventral Intermediate Nucleus of the Thalamus in 3 Cases of Myoclonus-Dystonia Syndrome.

Surgical approaches of internal globus pallidus (GPi) and ventral intermediate thalamic nucleus (Vim) have been used to treat different movement disorders. Three subjects with myoclonus-dystonia syndrome were surgically treated, one of them with GPi and Vim stimulation, while radiofrequency ablation of these structures was performed in the other 2 subjects. Surgical approach of both targets was performed simultaneously on each subject. Mean follow-up was of 33.3 months (22-48 months), the Unified Myoclonus Rating Scale action myoclonus (AM), functional tests (FT), patient questionnaire (PQ) sub-scores, and the Unified Dystonia Rating Scale (UDRS) were used during assessments. Improvement in all scales were seen 6 months after surgery (AM: 74%, FT: 60%, PQ: 63%, UDRS: 65%), and this benefit persisted throughout follow-up (AM: 61%, FT:62%, PQ: 65%, UDRS: 86%). No adverse events were noticed. Simultaneous unilateral procedures of GPi and Vim by either stimulation or ablation techniques improve both motor and functional scores in myoclonus-dystonia syndrome.

Posterior spinal cord stimulation in a case of painful legs and moving toes.

A 59-year-old woman with a 5-year history of right lower limb pain is reported. Symptoms developed initially when walking and progressively became bilateral, appeared at rest and involuntary movements of the toes became evident. A diagnosis of painful legs and moving toes was made. As several drug therapies proved unsuccessful, a therapeutic test with a tetrapolar epidural lead to stimulate the spinal cord dorsal tracts was performed. Due to the marked improvement the device and generator were implanted and she has responded satisfactorily to this therapy for the past 13 months.
