A pain in the pocket: Prevalence of pocket pain in patients with implantation of neuromodulation systems: A retrospective study.

INTRODUCTION: Implantable pulse generator (IPG) is a neurostimulation therapy mediated by electrodes and surgically implanted in a subcutaneous "pocket" used for the control of numerous pathologies. This study examines both the prevalence of pain associated with IPG implantation ("pain pocket syndrome") and its associated characteristics. MATERIALS AND METHODS: 56 patients with an IPG were included in the study. A health questionnaire was conducted to determine the presence of pain associated with the pocket and its neuropathic characteristics, as well as associated aesthetic concerns, location, situations that accentuate or alleviate pain, medications used for baseline and pocket pain control and other factors associated. RESULTS: Pain in the area of implantation of the IPG had a prevalence of 52.6% of patients (n = 27), in our sample, with a mean score on the visual analogic scale (VAS) of 4.9 points [3.9 - 5.8 points], with neuropathic characteristics in 53.3% (n = 16) of the patients with pain, with differences between the mean VAS score of the female (5.5 [4.3 - 5.8 points]) and males (3.5 points [2.1 - 4.9 points]) (p = 0.04). CONCLUSION: Pocket pain is a condition with a higher prevalence than described in previous studies, being of a higher intensity in females, involving a moderate pain in the area of implantation of the neuromodulating therapy. This pain has neuropathic characteristics and could require a repositioning intervention. Hence, more studies in this field should be carried to detect and prevent this syndrome.

Consenso Baiona sobre Incontinencia Fecal: Asociación Española de Coloproctología / Baiona's Consensus Statement for Fecal Incontinence. Spanish Association of Coloproctology

La incontinencia fecal (IF) constituye un importante problema sanitario, tanto a nivel individual como para los diferentes sistemas de salud, lo que origina una preocupación generalizada para su resolución o, al menos, disminuir en lo posible los numerosos efectos indeseables que provoca, al margen del elevado gasto que ocasiona. Existen diferentes criterios relacionados con las pruebas diagnósticas a realizar, y lo mismo acontece con relación al tratamiento más adecuado, dentro de las numerosas opciones que han proliferado durante los últimos años, no siempre basadas en una rigurosa evidencia científica. Por dicho motivo, desde la Asociación Española de Coloproctología (AECP) nos propusimos elaborar un Consenso que sirviese de orientación a todos los profesionales sanitarios interesados en el problema, conscientes, no obstante, de que la decisión terapéutica debe tomarse de manera individualizada: características del paciente/experiencia del terapeuta. Para su elaboración optamos por la técnica de grupo nominal. Los niveles de evidencia y los grados de recomendación se establecieron de acuerdo a los criterios del Oxford Centre for Evidence-Based Medicine. Por otra parte, en cada uno de los ítems analizados se añadieron, de forma breve, recomendaciones de los expertos.(AU)

Faecal incontinence (FI) is a major health problem, both for individuals and for health systems. It is obvious that, for all these reasons, there is widespread concern for healing it or, at least, reducing as far as possible its numerous undesirable effects, in addition to the high costs it entails. There are different criteria for the diagnostic tests to be carried out and the same applies to the most appropriate treatment, among the numerous options that have proliferated in recent years, not always based on rigorous scientific evidence. For this reason, the Spanish Association of Coloproctology (AECP) proposed to draw up a Consensus to serve as a guide for all health professionals interested in the problem, aware, however, that the therapeutic decision must be taken on an individual basis: patient characteristics/experience of the care team. For its development it was adopted the Nominal Group Technique methodology. The Levels of Evidence and Grades of Recommendation were established according to the criteria of the Oxford Centre for Evidence-Based Medicine. In addition, expert recommendations were added briefly to each of the items analysed.(AU)

Estimulación cerebral profunda combinada del núcleo subtalámico y el globo pálido interno en la enfermedad de Parkinson / Combined subthalamic nucleus and globus pallidus internus deep brain stimulation in Parkinson’s disease

Introducción: La estimulación cerebral profunda (ECP) del núcleo subtalámico (NST) y el globo pálido interno (GPi) son los principales abordajes quirúrgicos en la enfermedad de Parkinson avanzada. La estimulación suele aplicarse de forma bilateral en la misma estructura cerebral. Sin embargo, cuando diferentes síntomas motores se presentan concomitantemente en el mismo paciente, la modulación simultánea de diferentes estructuras cerebrales puede ser una alternativa eficaz. Caso clínico: Presentamos un paciente con enfermedad de Parkinson avanzada en el que se realizó ECP combinada en NST y el GPi. La ECP del NST izquierdo controló de manera óptima la sintomatología del hemicuerpo derecho, mientras que las discinesias problemáticas que presentaba en el hemicuerpo izquierdo se redujeron con éxito mediante la estimulación del GPi derecho. Discusión. La estimulación combinada del NST/GPi puede considerarse un enfoque neuroquirúrgico adecuado cuando surge una sintomatología motora desafiante en pacientes con enfermedad de Parkinson avanzada.(AU)

Introduction: Subthalamic nucleus (STN) and globus pallidus internus (GPi) deep brain stimulation (DBS) are the main surgical approaches for advanced Parkinson’s disease. Stimulation is usually applied bilaterally in the same brain structure. However, when various motor symptoms concomitantly present in the same patient, simultaneous modulation of different brain structures may be a suitable alternative. Case report: We present a patient with advanced Parkinson’s disease with a combined DBS neurosurgery. Left STN DBS optimally controlled the off right hemibody symptomatology while left side troublesome dyskinesias were successfully relieved by right GPi stimulation. Discussion: Combined STN/GPi stimulation can be considered a suitable approach when challenging motor symptomatology arises in advanced Parkinson’s disease patients.(AU)

Rationality for the Use of Neuromodulation in Disorders of Gut-Brain Interaction (Functional Gastrointestinal Disorders)

Within the broad range of therapeutic options for managing functional gastrointestinal disorders, recently redefined as Disorders of Gut-Brain Interaction (DGBI) by the Rome Foundation in the Rome IV criteria, certain medications with antidepressant, anxiolytic, or antipsychotic effects are commonly employed. These drugs, now referred to as neuromodulators by the Rome Foundation, target the neurogastroenterological dysfunction associated with these disorders. Consequently, their clinical utility as psychiatric medications can now be leveraged to benefit patients with DGBI. This narrative review aims to provide an updated and specific overview of the indications for neuromodulators in the primary DGBI. The first section of this review focuses on the rationale and justification for their use.

En el amplio espectro de las opciones terapéuticas para el manejo de los trastornos funcionales digestivos, que se han redefinido por la Fundación Roma en los criterios Roma IV como trastornos de la interacción cerebro-intestino (TICI), algunos medicamentos con efectos antidepresivos, ansiolíticos o antipsicóticos se utilizan con mayor frecuencia. Estos medicamentos, que actúan en la disfunción neurogastroenterológica de estos trastornos, también han sido renombrados por la Fundación Roma como neuromoduladores, para que ahora puedan aprovecharse sus beneficios terapéuticos en este ámbito clínico, debido a su utilización como medicamentos psiquiátricos. Esta revisión narrativa tiene por objeto actualizar y precisar las indicaciones de los neuromoduladores en los principales TICI, y en esta primera sección se aborda la racionalidad y justificación para su utilización.

Symptoms and pathophysiology of cluster headache. Approach to combined occipital and supraorbital neurostimulation.

Cluster headache (CH) is included under section 3 - Trigeminal autonomic cephalalgias (TAC) of the International Headache Society (IHS) classification. It is one of the most frequent, painful and disabling primary headaches. Acute and preventive pharmacological treatments are often poorly tolerated and of limited effectiveness. Due to improved understanding of the pathophysiology of CH, neuromodulation devices are now considered safe and effective options for preventive and acute treatment of CH. In this paper, we review the information available to date, and present the case of a patient with disabling cluster headache highly resistant to medical treatment who underwent implantation of a peripheral nerve neurostimulation system to stimulate the supraorbital nerves (SON) and greater occipital nerve (GON) in our Pain Unit. We also review the diagnostic criteria for CH, the state of the knowledge on the pathophysiology of CH, and the role played by neuromodulation in treating this condition.

Clínica y fisiopatología de la cefalea en racimos. Acercamiento a la indicación de neuroestimulación combinada occipital y supraorbitaria / Symptoms and pathophysiology of cluster headache. Approach to combined occipital and supraorbital neurostimulation

La cefalea en racimos (CR) se encuadra dentro del apartado 3 de la clasificación de la Sociedad Internacional de Cefaleas (IHS), que es el reservado para las llamadas cefaleas trigémino autonómicas (CTA). Se trata de uno de los procesos de cefalea primaria más frecuentes, dolorosos e incapacitantes. Los tratamientos farmacológicos agudos y preventivos son, en muchos casos, mal tolerados y de efectividad limitada. Debido a la mejora en la comprensión de su fisiopatología de la CR, los dispositivos de neuromodulación se han posicionado como opciones seguras y eficaces de tratamiento preventivo y el tratamiento agudo de la CR. Haremos un recorrido sobre la información disponible hasta el momento y además, exponemos el caso de un paciente con CR incapacitante, muy resistente al tratamiento médico, tratado en nuestra Unidad del Dolor con el implante de un sistema de neuroestimulación de nervio periférico de nervios supraorbitario (SON) y nervio occipital mayor (GON). A continuación revisaremos los criterios diagnósticos que la definen la CR, lo datos que conocemos, a día de hoy, sobre su fisiopatología y la posición que ocupa actualmente la neuromodulación en el abordaje terapéutico de la misma. Con la descripción del caso clínico de un paciente tratado en nuestra Unidad del Dolor con una cefalea especialmente severa y resistente al tratamiento farmacológico.(AU)

Estimulação Transcraniana para Transtornos do Sono: uma revisão sistemática / Transcranial Stimulation in Sleep Disorders: a systematic review / Estimulación Transcraneal para los Trastornos del Sueño: una revisión sistemática

Os transtornos do sono podem ter várias consequências para a cognição, comportamento e vida social das pessoas. No entanto, a terapia utilizada para avaliar e intervir nesses transtornos ainda não está consolidada. Nesse contexto, o objetivo deste estudo foi verificar a aplicabilidade e eficácia da estimulação transcraniana (ETCA / ETCC / EMTr) nos transtornos do sono. Foi realizada uma busca sistemática de acordo com as diretrizes do PRISMA nas bases de dados Web of Science, PubMed, LILACS e SciELO. Inicialmente, foram encontrados 448 artigos, de acordo com os critérios de elegibilidade. O banco de dados de evidências de fisioterapia (PEDro) foi utilizado para avaliar a qualidade metodológica dos 11 artigos finais. Em geral, os resultados indicam que há tanto relatos favoráveis quanto desfavoráveis à eficácia do uso terapêutico das técnicas de estimulação transcraniana nos transtornos do sono e, portanto, ainda se configura como uma questão em aberto, dependendo de múltiplos fatores metodológicos e conceituais.

Sleep disorders can have several consequences on people's cognition, behavior and social life. However, the therapy used to assess and intervene in these disorders is not yet consolidated. In this context, the aim of this study was to verify the applicability and effectiveness of transcranial stimulation (tACS / tDCS / rTMS) in sleep disorders. A systematic search was performed according to PRISMA guidelines in the Web of Science, PubMed, LILACS, and SciELO databases. Initially, 448 articles were found, according to the eligibility criteria. The physiotherapy evidence database (PEDro) was used to assess the methodological quality of the 11 final articles. In general, the results indicate that there are both favorable and unfavorable reports on the effectiveness of the therapeutic use of transcranial stimulation techniques in sleep disorders and, therefore, it is still an open question, depending on multiple methodological and conceptual factors.

Experiencia de la neuromodulación en un hospital de alta complejidad / High Complexity Hospital ́s experience in neuromodulation

La neuromodulación es una práctica médica implementada desde hace más de cuatro décadas. En lo que respecta a la Neurocirugía, cumple un papel en el tratamiento de diversas patologías (Parkinson, distonías, epilepsia, etc.) y con un gran potencial para aplicarlas en otras (trastorno obsesivo compulsivo [TOC], dolor pélvico). Es por ello que, en los últimos años, se cuadruplicaron las inversiones de empresas biotecnológicas en este campo por la demanda y aplicación de la terapia. La neuromodulación abarca también otras especialidades, como por ejemplo Otorrinolaringología (ORL) en implantes cocleares, Cardiología con diversos modelos de marcapasos cardíacos, Endocrinología con bombas de infusión de medicamentos, Uroginecología en incontinencia, etcétera. Nuestra institución aplica en su práctica clínica todas estas técnicas, y cumple una función jerárquica como centro de referencia en educación y políticas sanitarias. Por estos aspectos, sumados a su infraestructura, personal profesional y enfoque sanitario, puede ser considerada como un Centro de Neuromodulación referente en la región. (AU)

Neuromodulation is a medical practice established for more than forty years. In the neurosurgical field it plays a role in the treatment of different diseases (Parkinson, Dystonia, Epilepsy, etc) and has a great potential to apply in other pathologies (Obsessive Compulsive Disorder, Pelvic pain). In the last years the biotechnological industry has quadrupled the investment in this field because of the demand and therapy application. Neuromodulation encompasses other specialities, for example otorhinolaryngology in cochlear implants, in cardiology with different models of pacemakers, endocrinology with implanted infusion pumps, urological gynecology in incontinence treatments, etc. Our institution applies all these techniques in its clinical practice, having a hierarchical role as a reference center in education and health policies. Due to these aspects, added to its infrastructure, professional staff and health approach, it can be considered as a reference Neuromodulation Center in the region. (AU)

Dentro de las técnicas de tratamiento, la neuromodulación periférica del nervio tibial posterior (NMTP) está reconocida internacionalmente como una de las vías de abordaje, aunque no se ha probado un protocolo óptimo. El objetivo de esta revisión es conocer la evidencia disponible sobre cuál es el protocolo de la técnica de NMTP más empleado en la obtención de buenos resultados en el tratamiento de VH en mujeres.Adquisición de la evidenciaSe llevó a cabo una revisión sistemática de la literatura científica en las bases de datos Pubmed, Embase, WOS y Scopus. Se obtuvieron 222 resultados, con 58 duplicados, de los cuales 8 estudios cumplieron los criterios de inclusión establecidos, todos ellos ensayos clínicos aleatorizados.Síntesis de la evidenciaLa técnica de NMTP más utilizada en los trabajos incluidos que muestran estos resultados beneficiosos en mujeres con VH es la percutánea con una aguja colocada 5-6cm en posición proximal al maléolo tibial, por detrás del borde de la tibia y con los parámetros de 200μs de duración de impulso, 20Hz de frecuencia, 30 minutos de tiempo por sesión y con una frecuencia que podría ser de una sesión por semana durante 12 semanas.ConclusiónLa NMTP puede tener efectos beneficiosos y seguros a corto plazo en la VH en mujeres. A pesar de mostrar mejorías estadísticamente significativas en los síntomas clínicos, son necesarias más investigaciones para poder obtener evidencias científicas claras sobre el tipo de protocolo óptimo para el tratamiento de la VH en mujeres.

Introduction: Overactive bladder syndrome (OBS) is a urological disorder characterized by urinary urgency, increased frequency, nocturia, and may be associated with urge urinary incontinence. Posterior tibial nerve peripheral neuromodulation (PTNS) is globally recognized within the treatment options available, although an optimal protocol has not been tested. The objective of this review is to collect the evidence available on the most widely used protocol of the PTNS technique in obtaining good results in the treatment for women with OBS.Evidence acquisitionA systematic review of the scientific literature was carried out in PubMed, Embase, WoS and Scopus databases. A total of 222 results were obtained, with 58 duplicates, of which 8 studies met the established inclusion criteria, all of them randomized clinical trials.Evidence synthesisThe included works show that the most widely used PTNS technique with beneficial results in women with OBS is the percutaneous route with a needle placed 5-6cm proximal to the tibial malleolus, posterior to the edge of the tibia, with the following parameters: 1 weekly session of 30minutes duration for 12 weeks, the use of pulse widths of 200μs with frequency of 20Hz.ConclusionPTNS may have beneficial and safe short-term effects in women with OBS. Despite showing statistically significant improvements in clinical symptoms, further research is needed to obtain clear scientific evidence on the optimal protocol for treating women with OBS. (AU)

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

Neuromodulation in headache and craniofacial neuralgia: guidelines from the Spanish Society of Neurology and the Spanish Society of Neurosurgery. / Neuromodulación en cefaleas y neuralgias craneofaciales: Guía de la Sociedad Española de Neurología y de la Sociedad Española de Neurocirugía.

INTRODUCTION: Numerous invasive and non-invasive neuromodulation devices have been developed and applied to patients with headache and neuralgia in recent years. However, no updated review addresses their safety and efficacy, and no healthcare institution has issued specific recommendations on their use for these 2 conditions. METHODS: Neurologists from the Spanish Society of Neurology's (SEN) Headache Study Group and neurosurgeons specialising in functional neurosurgery, selected by the Spanish Society of Neurosurgery (SENEC), performed a comprehensive review of articles on the MEDLINE database addressing the use of the technique in patients with headache and neuralgia. RESULTS: We present an updated review and establish the first set of consensus recommendations of the SEN and SENC on the use of neuromodulation to treat headache and neuralgia, analysing the current levels of evidence on its effectiveness for each specific condition. CONCLUSIONS: Current evidence supports the indication of neuromodulation techniques for patients with refractory headache and neuralgia (especially migraine, cluster headache, and trigeminal neuralgia) selected by neurologists and headache specialists, after pharmacological treatment options are exhausted. Furthermore, we recommend that invasive neuromodulation be debated by multidisciplinary committees, and that the procedure be performed by teams of neurosurgeons specialising in functional neurosurgery, with acceptable rates of morbidity and mortality.
