Combined thalamic and pallidal deep brain stimulation in diabetic hemiballism/hemichorea.

Hemiballism/Hemichorea (HH) is a hyperkinetic movement disorder observed mostly after cerebrovascular diseases in elderly patients. Even though the improvement in symptoms would be maintained without treatment, in rare cases, lesioning or DBS (deep brain stimulation) surgery provide a chance on relieving the severe involuntary movements. HH is a more rarely reported entity as a diabetic complication and we encountered very few cases treated with surgical intervention for diabetic HH. A 75-year-old female patient with type-II diabetes mellitus was admitted for left-sided disabling involuntary movement despite being medically treated for six months. A GPi (globus pallidus internus) and thalamic Vim (ventral intermediate) nucleus targeted DBS surgery was performed. Complete resolution was achieved with combined stimulation at 1.7 mA of thalamic Vim nucleus and 2.4 mA of GPi. Combined stimulation of thalamic Vim nucleus and GPi resulted in an effective treatment method for HH secondary to diabetes in our case. Even if the rarity of the cases treated surgically withholds us to come to a certain conclusion, it provides a new option to treat HH to our experience.

Gasserian ganglion stimulation for refractory trigeminal neuropathic pain.

BACKGROUND AND OBJECTIVE: Painful trigeminal neuropathy is a complex clinical entity due to its severity and refractoriness to pharmacological and interventional management. We describe our experience in treating refractory painful trigeminal neuropathy (RPTN) with gasserian ganglion stimulation (GGS). MATERIALS AND METHODS: Six patients with RPTN were treated with GGS in our Unit between 2019 and 2022. The following data were collected: socio-demographic characteristics, triggering event, duration of the disease and treatment received prior to surgery, pre- and post-intervention visual analogue scale (VAS) score, follow-up time, and pre- and post-intervention functionality and quality of life. RESULTS: All patients were women who had received aggressive first-, second-, and third-line pharmacological, non-pharmacological, and interventional management before being referred for GGS. Patients reported a 50%-72% decrease in pain on VAS and improved functionality during follow-up. CONCLUSIONS: GGS is a promising therapeutic alternative for patients with RPTN. Although the initial outcomes and experience are encouraging, RPTN is recommended on the basis of safety, reproducibility, and trends observed in clinical practice.

Intracerebral hemorrhage after deep brain stimulation surgery guided with microelectrode recording: analysis of 297 procedures / Hemorragia intracerebral después de cirugía de estimulación cerebral profunda guiada por microrregistro: un análisis de 297 procedimientos

Objectives: Report the incidence of symptomatic and asymptomatic intracerebral hemorrhage (ICH) in patients submitted to deep brain stimulation (DBS) guided with microelectrode recording (MER) with further analysis of potential risk factors, both inherent to the patient and related to the pathology and surgical technique. Methods: We performed a retrospective observational study. 297 DBS procedures were concluded in 277 patients in a single hospital centre between January 2010 and December 2020. All surgeries were guided with MER. We analysed the incidence of symptomatic and asymptomatic ICH and its correlation to age, sex, diagnosis, hypertension and perioperative hypertension, diabetes, dyslipidaemia, antiplatelet drugs, anatomic target, and number of MER trajectories. Results: There were a total of 585 electrodes implanted in 277 patients. 16 ICH were observed, of which 6 were symptomatic and 10 asymptomatic, none of which incurred in permanent neurological deficit. The location of the hemorrhage varied between cortical and subcortical plans, always in relation with the trajectory or the final position of the electrode. The incidence of symptomatic ICH per lead-implantation was 1%, and the CT-scan demonstrated asymptomatic ICH in 1.7% more patients. Male patients or with hypertension are 2.7 and 2.2 times more likely to develop ICH, respectively. However, none of these characteristics has been shown to have a statistically significant association with the occurrence of ICH, as well as age, diagnosis, diabetes, dyslipidaemia, antiplatelet drugs, anatomic target, number of MER trajectories and perioperative hypertension. Conclusions: MER-guided DBS is a safe technique, with low incidence of ICH and no permanent deficits in our study. Hypertension and male sex seem to be risk factors for the development of ICH in this surgery. Nevertheless, no statistically significant factors were found for the occurrence of this complication.(AU)

Objetivos: Reportar la incidencia de hemorragia intracerebral (HIC) sintomática y asintomática en pacientes sometidos a estimulación cerebral profunda (ECP) guiada por microrregistro (MER), con el consecuente análisis de posibles factores de riesgo, tanto inherentes al paciente como relacionados con la patología y técnica quirúrgica. Métodos: Realizamos un estudio observacional retrospectivo. Se analizaron un total de 297 procedimientos de ECP realizados en 277 pacientes en un centro hospitalario entre enero de 2010 y diciembre de 2020. Todas las cirugías fueron guiadas con MER. Analizamos la incidencia de HIC, tanto sintomática como asintomática, y la correlación con edad, sexo, diagnóstico, hipertensión arterial e intraoperatoria, diabetes, dislipemia, medicación antiplaquetaria previa, diana anatómica y número de vías. Resultados: El número total de electrodos implantados fue de 585 en 277 pacientes. Se observaron 16 HIC, de las cuales 10 fueron asintomáticas y 6 sintomáticas y ninguna incurrió en déficit neurológico permanente. La localización de la hemorragia varió entre planos corticales y subcorticales, siempre en relación con el trayecto o posición final del electrodo. La incidencia de hemorragia sintomática fue de alrededor del 1 %, y la TC posoperatoria demostró hemorragia asintomática en un 1,7 % adicional de los pacientes. Los pacientes varones o los pacientes con hipertensión tienen 2,7 y 2,2 veces más probabilidades de desarrollar sangrado, respectivamente. Sin embargo, ninguna de estas características demostró una asociación estadísticamente significativa con la ocurrencia de hemorragia intracerebral, como la edad, el diagnóstico, la diabetes, la dislipidemia, la ingesta previa de medicamentos antiplaquetarios, el objetivo anatómico, el número de MER y las vías de HTA intraoperatorias. Conclusión: La ECP con MER es una técnica segura, con baja incidencia de HIC y sin déficits permanentes en nuestro estudio...(AU)

Covid-19 in Parkinson's Disease treated by drugs or brain stimulation / COVID-19 en la enfermedad de Parkinson tratada con fármacos o estimulación cerebral

Purpose: Covid-19 has affected all people, especially those with chronic diseases, including Parkinson's Disease (PD). Covid-19 may affect both motor and neuropsychiatric symptoms of PD patients. We intend to evaluate different aspects of Covid-19 impact on PD patients. Methods: 647 PD patients were evaluated in terms of PD-related and Covid-19-related clinical presentations in addition to past medical history during the pandemic through an online questioner. They were compared with an age-matched control group consist of 673 individuals and a sample of the normal population consist of 1215 individuals. Results: The prevalence of Covid-19 in PD patients was 11.28%. The mortality was 1.23% among PD patients. The prevalence of Covid-19 in PD patients who undergone Deep Brain Stimulation (DBS) was 18.18%. No significant association was found between the duration of disease and the prevalence of Covid-19. A statistically significant higher prevalence of Covid-19 in PD patients who had direct contact with SARS-CoV-19 infected individuals was found. No statistically significant association has been found between the worsening of motor symptoms and Covid-19. PD patients and the normal population may differ in the prevalence of some psychological disorders, including anxiety and sleeping disorders, and Covid-19 may affect the psychological status. Conclusion: PD patients possibly follow tighter preventive protocols, which lead to lower prevalence and severity of Covid-19 and its consequences in these patients. Although it seems Covid-19 does not affect motor and psychological aspects of PD as much as it was expected, more accurate evaluations are suggested in order to clarify such effects.(AU)

Objetivo: La COVID-19 ha afectado a toda la población, especialmente a aquellos con enfermedades crónicas, incluyendo a los pacientes con enfermedad de Parkinson (EP). La COVID-19 puede empeorar tanto los signos motores como los síntomas neuropsiquiátricos de los pacientes con EP. El objetivo de este estudio es evaluar diferentes aspectos del impacto de la COVID-19 en los pacientes con EP. Métodos: A través de un cuestionario virtual se evaluó a 647 pacientes con EP de acuerdo con sus presentaciones clínicas relacionadas con la EP y con la COVID-19, además de la historia médica previa durante la pandemia. Se compararon con un grupo de controles sanos de la misma edad que constaba de 673 individuos y una muestra de la población general de 1.215 individuos. Resultados: La prevalencia de la COVID-19 en pacientes con EP fue del 11,28%. La mortalidad fue del 1,23% entre los pacientes con EP. La prevalencia de COVID-19 en pacientes con EP con estimulación cerebral profunda fue del 18,18%. No se encontró una asociación significativa entre la duración de la enfermedad y la prevalencia de COVID-19. Se halló una prevalencia mayor de COVID-19 que fue estadísticamente significativa en pacientes con EP que tuvieron contacto directo con personas infectadas con SARS-CoV-2. No se encontró una asociación estadísticamente significativa entre el empeoramiento de los signos motores y la COVID-19. Los pacientes con EP y la población general podrían diferir en la prevalencia de algunos trastornos psicológicos, incluidos los trastornos de ansiedad y del sueño, y la COVID-19 podría afectar al estado psicológico. Conclusión: Los pacientes con EP posiblemente sigan protocolos preventivos más estrictos, lo que conduce a una menor prevalencia y gravedad de COVID-19 y de sus consecuencias en estos pacientes.(AU)

Essential Tremor: Update of Therapeutic Strategies. / Temblor esencial: actualización de las estrategias terapéuticas.

In the last decades there has been progress in the treatment of essential tremor (TE) especially in the surgical field and to a lesser extent in the pharmacological field. We carry out a review of the currently available treatments. The first intervention is the use of non-pharmacological and non-surgical strategies (general advice, occupational therapy, speech therapy, psychotherapy). With discrete advances, the pharmacological treatment is not very satisfactory. Only 30-60% of patients have a positive response, and in these the anti-tremor effectiveness is 40-60%. The first-line drugs are still propranolol and primidone. In cases with severe tremor we will consider a surgical option, the method of choice being thalamotomy using high-intensity focused ultrasound. In the future we must continue to study the pathophysiology of TE, develop drugs specifically designed for TE and improve the technology of available invasive techniques.

Although it seems Covid-19 does not affect motor and psychological aspects of PD as much as it was expected, more accurate evaluations are suggested in order to clarify such effects.

Management of pudendal neuralgia with electrical stimulation. A systematic review.

INTRODUCTION AND OBJECTIVE: Pudendal neuralgia is a severely intense, painful, neuropathic condition, involving the dermatome of the pudendal nerve (S2, S3, S4). The diagnosis is complex and usually takes many years to be made. Techniques that use electrical current have been shown to decrease pain and improve quality of life in patients with this condition. The aim of this review was to analyze the existing literature on the effects of electrical current in the treatment of patients with pudendal neuralgia. MATERIAL AND METHODS: A literature search was carried out in PubMed, Cinahl, Medline, Cochrane Library, ENFISPO, PEDro, Scopus and Web of Science databases, using the search terms "Electric Stimulation Therapy", "pudendal neuralgia" and "pudendal nerve entrapment". RESULTS: The most frequently repeated intervention is pulsed radiofrequency. Other techniques used are transcutaneous electrical nerve stimulation, pulsed electromagnetic field therapy and neuromodulation. All studies show significant improvement in pain, analgesic intake, depression-anxiety or quality of life. CONCLUSIONS: The application of electrical current seems to be effective in the management of pudendal neuralgia. The scientific evidence is scarce, of poor methodological quality, and its use is based on the efficacy demonstrated in other indications of chronic pain.

Caracterización y tratamiento de la enuresis en pacientes con vejiga hiperactiva / Characterization and treatment of enuresis in overactive bladder patients

Objetivos: Definir los tipos de enuresis de los pacientes con vejiga hiperactiva (VH) y estudiar su respuesta al tratamiento vesical diurno. Material y métodos. Estudio prospectivo y multicéntrico: pacientes con VH y enuresis, tratados con anticolinérgicos o neuromodulación durante 3 meses (2019-2021). Recogimos variables obtenidas del calendario miccional, cuestionario PLUTSS (Pediatric Lower Urinary Tract Score System), y relacionadas con la enuresis. Generamos 2 grupos de estudio: enuresis primaria (EP) y enuresis secundaria (ES). Consideramos respuesta parcial enurética (RPE) a la reducción del valor de enuresis inicial en más de un 50% y respuesta completa (RCE) el 100%. Finalmente realizamos un análisis multivariante para detectar factores predictivos independientes de RCE. Resultados. Incluimos 152 pacientes con VH, 109 de los cuales presentaban enuresis (71,7%): 29 ES (26,7%) y 80 EP (73,3%). El valor PLUTSS fue mayor en pacientes con EP que en ES (20,8 vs. 17,2, p= 0,001.) La RPE y la RCE fueron significativamente mayores en el grupo de ES (55,2% vs. 15%, p= 0,000 en RPE y 48,3% vs. 5%, p= 0,000 en RCE). En el análisis multivariante se identificó que los pacientes con ES tienen una probabilidad de responder al tratamiento vesical diurno 50 veces superior que los pacientes con EP (OR 49,79, IC95% 6,73-36,8). Conclusiones. La mayoría de niños con VH tienen una EP y no secundaria, por lo que generalmente la enuresis de estos pacientes no responde al tratamiento vesical diurno. Es importante caracterizar el tipo de enuresis de los niños con VH para plantear su tratamiento de forma adecuada.(AU)

Objective: To define the types of overactive bladder (OAB) patient enuresis and study daytime bladder treatment response. Materials and methods. A prospective, multi-center study of OAB patients with enuresis treated with anticholinergics or neuromodulation over 3 months from 2019 to 2021 was carried out. Variables achieved from the voiding calendar and PLUTSS (Pediatric Lower Urinary Tract Score System), as well as enuresis-related variables, were collected. Two study groups were created – primary enuresis (PE) and secondary enuresis (SE). Partial enuretic response (PER) was defined as a >50% reduction in baseline enuresis, and complete enuretic response (CER) as a 100% reduction. A multivariate analysis was eventually conducted to detect CER independent predictive factors. Results. 152 OAB patients were included. 109 of them (71.7%) had enuresis – 29 (26.7%) SE and 80 (73.3%) PE. PLUTSS score was higher in PE patients than in SE patients (20.8 vs. 17.2; p= 0.001). PER and CER were significantly higher in the SE group (55.2% vs. 15%; p= 0.000 in PER, and 48.3% vs. 5%; p= 0.000 in CER). In the multivariate analysis, SE patients demonstrated to have a 50-fold increased probability of responding to daytime bladder treatment than PE patients (OR: 49.79; 95%CI: 6.73-36.8). Conclusions. Most OAB children have PE and not SE, which explains why enuresis does not typically respond to daytime bladder treatment. Characterizing the type of enuresis in OAB children is important to adequately approach treatment.(AU)

Self-expanding TAVI using the cusp overlap technique versus the traditional technique: electrocardiogram changes and 1-year cardiovascular outcomes.

INTRODUCTION AND OBJECTIVES: Transcatheter aortic valve implantation (TAVI) using the cusp overlap technique (COT) has shown a lower pacemaker implantation rate at 30 days. The objective of this study was to compare electrocardiogram changes and clinical outcomes between COT and the traditional technique (TT) at 1 year of follow-up. METHODS: Observational, retrospective, nonrandomized study of consecutive patients undergoing TAVI between January 2015 and January 2021. Patients were matched using a propensity score and the TT was compared with COT. The primary endpoints were electrocardiogram changes and a combined endpoint including pacemaker implantation, hospitalization, or cardiovascular death at 1 year. RESULTS: We included 254 patients. After propensity score matching, 184 patients (92 per group) remained. There were no statistically significant differences in baseline characteristics. At 1 year, COT patients showed a significant reduction in new onset left bundle branch block (49% vs 27%, P=.002) and less P wave (13.1±21.0 msec vs 5.47±12.5 msec; P=.003) and QRS prolongation (29.77±27.0 msec vs 16.38±25.4 msec, P <.001). COT was associated with a significant reduction in the occurrence of the primary endpoint (SHR, 0.39 [IC95%, 0.21-0.76]; P=.005). CONCLUSIONS: At 1 year of follow-up, COT reduced the incidence of new onset left bundle branch block and diminished QRS and P wave widening compared with the TT. COT was also associated with a statistically significant reduction in the occurrence of the combined primary cardiovascular endpoint.

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)

Intracerebral hemorrhage after deep brain stimulation surgery guided with microelectrode recording: analysis of 297 procedures.

OBJECTIVES: Report the incidence of symptomatic and asymptomatic intracerebral hemorrhage (ICH) in patients submitted to deep brain stimulation (DBS) guided with microelectrode recording (MER) with further analysis of potential risk factors, both inherent to the patient and related to the pathology and surgical technique. METHODS: We performed a retrospective observational study. 297 DBS procedures were concluded in 277 patients in a single hospital centre between January 2010 and December 2020. All surgeries were guided with MER. We analysed the incidence of symptomatic and asymptomatic ICH and its correlation to age, sex, diagnosis, hypertension and perioperative hypertension, diabetes, dyslipidaemia, antiplatelet drugs, anatomic target, and number of MER trajectories. RESULTS: There were a total of 585 electrodes implanted in 277 patients. 16 ICH were observed, of which 6 were symptomatic and 10 asymptomatic, none of which incurred in permanent neurological deficit. The location of the hemorrhage varied between cortical and subcortical plans, always in relation with the trajectory or the final position of the electrode. The incidence of symptomatic ICH per lead-implantation was 1%, and the CT-scan demonstrated asymptomatic ICH in 1.7% more patients. Male patients or with hypertension are 2.7 and 2.2 times more likely to develop ICH, respectively. However, none of these characteristics has been shown to have a statistically significant association with the occurrence of ICH, as well as age, diagnosis, diabetes, dyslipidaemia, antiplatelet drugs, anatomic target, number of MER trajectories and perioperative hypertension. CONCLUSIONS: MER-guided DBS is a safe technique, with low incidence of ICH and no permanent deficits in our study. Hypertension and male sex seem to be risk factors for the development of ICH in this surgery. Nevertheless, no statistically significant factors were found for the occurrence of this complication.

Comparison of intraoperative imaging guided versus microelectrode recording guided deep brain stimulation for Parkinson's disease: A meta-analysis / Comparativa entre la cirugía guiada por imágenes y la estimulación cerebral profunda guiada por microelectrodos en el tratamiento de la enfermedad de Parkinson: un metaanálisis

Background Traditionally, most centers would use microelectrode recording (MER) to refine targeting in deep brain stimulation (DBS) surgery. In recent years, intraoperative imaging (IMG) guided DBS has become an alternative way to verify lead placement. Currently, there is still controversy surrounding the necessity of MER or IMG for DBS. This meta-analysis aims to explore lead accuracy, clinical efficacy and safety between IMG and MER guided DBS for Parkinson's disease (PD). Methods PubMed, Embase, Web of Science, Cochrane Library were searched up to Mar, 2021 for studies reporting comparisons between IMG and MER guided DBS for PD. Subgroup analysis was conducted to assess effects of different IMG technology and DBS targeting site. Results Six studies, comprising of 478 patients were included in our analysis. The mean difference between the two implantation techniques in stereotactic accuracy, lead passes per trajectory, improvement% of Unified Parkinson's Disease Rating Scale part III and levodopa equivalent daily dose were −0.45 (95% confidence interval, CI=−1.11 to 0.20), −0.18 (95% CI=−0.41 to 0.06), 3.40 (95% CI=−5.36 to 12.16), and 5.00 (95% CI=−1.40 to 11.39), respectively. No significant differences were observed in each adverse event and operation/procedure time between the two implantation techniques. Conclusions Both IMG and MER guided DBS offered effective control of motor symptoms for PD. Besides, IMG guided is comparable to MER guided DBS, in terms of safety, accuracy and efficiency. It is recommended for each hospital to select DBS guidance technology based on available resources and equipment (AU)

Antecedentes Tradicionalmente, la mayoría de los centros usaban los microelectrodos de registro (microelectrode recording [MER]) para mejorar la orientación en la cirugía mediante la estimulación cerebral profunda (deep brain stimulation [DBS]). En los últimos años, la DBS orientada mediante imágenes intraoperatorias (intraoperative imaging guided [IMG]) se ha convertido en una forma alternativa de verificar la colocación de los electrodos. Hoy en día, todavía existe controversia en torno al uso de MER o IMG para realizar una DBS. Este metaanálisis tiene como objetivo explorar la precisión de los electrodos, la eficacia clínica y la seguridad entre la DBS guiada mediante IMG y MER en el tratamiento de la enfermedad de Parkinson (EP). Métodos Se realizaron búsquedas en PubMed, Embase, Web of Science y Cochrane Library hasta marzo de 2021 para localizar estudios que informasen sobre comparaciones entre la DBS guiada mediante IMG y la guiada mediante MER en la EP. Se realizó un análisis de subgrupos para evaluar los efectos de una tecnología IMG y una ubicación DBS guiada diferentes. Resultados En nuestro análisis hemos incluido seis estudios con 478 pacientes. La diferencia media entre las dos técnicas de implantación en la precisión estereotáctica, los pasos del electrodo por trayectoria, el porcentaje de mejora de la escala unificada de clasificación de la enfermedad de Parkinson, parteIII, y la dosis diaria equivalente de levodopa fueron −0,45 (intervalo de confianza del 95% [IC 95%]: −1,11 a 0,20), −0,18 (IC 95%: −0,41 a 0,06), 3,40 (IC 95%: −5,36 a 12,16) y 5,00 (IC 95%: −1,40 a 11,39), respectivamente. No se observaron diferencias significativas en cada evento adverso y tiempo de operación/procedimiento entre las dos técnicas de implantación (AU)

Utilidad de la monitorización neurofisiológica intraoperatoria como valor pronóstico de la parálisis facial posquirúrgica en schwannomas vestibulares / Utility of the intraoperative neurophysiological monitoring as a prognostic value of postoperative facial paresis in vestibular schwannomas

Antecedentes y objetivo La monitorización neurofisiológica intraoperatoria permite predecir la situación funcional del nervio facial tras la cirugía de schwannoma vestibular. Dada la gran variabilidad de los protocolos neurofisiológicos utilizados para ello, el objetivo del presente estudio es determinar la capacidad pronóstica del protocolo neurofisiológico usado en nuestro servicio. Material y métodos Se realizó un análisis estadístico de los datos de monitorización neurofisiológica recogidos en los pacientes intervenidos entre marzo de 2009 y julio de 2021 en el Servicio de Neurocirugía de Salamanca según su situación funcional, tanto en el período posquirúrgico inmediato como al año de la cirugía. Resultados Se analizó a 51 pacientes de entre 46 y 63 años (mediana: 54). Al estudiar el valor umbral de la intensidad de estimulación del nervio facial y la variación de los potenciales motores evocados córtico-bulbares, se hallaron diferencias significativas (p=0,043 y p=0,011, respectivamente) entre los pacientes con buena y mala situación clínica tras la cirugía. El valor umbral de intensidad más discriminativo fue 0,35mA (sensibilidad: 85%; especificidad: 48%). No se halló relación estadística en el grupo de estudio al año de la cirugía. Conclusiones El protocolo de monitorización intraoperatoria utilizado nos permite predecir la situación clínica de los pacientes en el período posquirúrgico inmediato y mejorar la información al paciente y sus familiares tras la intervención. No podemos, en cambio, utilizar estos parámetros para la predicción de la situación funcional al año de la cirugía ni para la toma de decisiones clínicas al respecto (AU)

Background and objective Intraoperative neurophysiological monitoring allows us to predict the functional status of the facial nerve after vestibular schwannoma surgery. Due to the great variability of the neurophysiological protocols used for it, the goal of this study is to determine the prognostic ability of our neurophysiological protocol. Material and methods We have performed a statistical analysis of the neurophysiological monitoring data collected from patients operated between March 2009 and July 2021 at the Neurosurgery Service of Salamanca according to their functional status, both in the immediate post-surgical period and one year after surgery. Results A number of 51 patients between 46 and 63 years old (median: 54) were analyzed. We have found significant differences studying the threshold value of the stimulation intensity of the facial nerve and the variation of the Cortico-bulbar Evoked Motor Potentials (P=0.043 and P=0.011, respectively) between the patients with good and bad clinical situation after surgery. The most discriminating intensity threshold value was 0.35mA (Sensitivity: 85%; Specificity: 48%). No statistical relationship was found in the study group one year after surgery. Conclusions Our intraoperative monitoring protocol allows us to predict the clinical situation of patients in the immediate postoperative period and improve information for the patient and her relatives after surgery. We cannot, however, use these parameters to predict the functional situation one year after surgery and make clinical decisions in this regard (AU)

Estimulación cerebral profunda subtalámica en un caso de enfermedad de Parkinson idiopática y esquizofrenia / Subthalamic deep brain stimulation in a case of idiopathic Parkinson’s disease and schizophrenia

Introducción La enfermedad de Parkinson (EP) y la esquizofrenia pueden coexistir. Los antipsicóticos bloquean los receptores D2 estriados, lo que inevitablemente agrava las manifestaciones de la EP. Caso clínico Presentamos el caso de un paciente con enfermedad de Parkinson idiopática y esquizofrenia, con pobre tolerancia a dosis mínimas de levodopa, que presentó una gran mejoría tras la estimulación cerebral profunda subtalámica bilateral (ECP-NST). La ECP-NST se consideró aquí, debido a la gravedad de este caso particular, como la única posibilidad de lograr una mejoría motora. Conclusiones El diagnóstico de EP idiopática se confirmó pese al tratamiento antidopaminérgico. La ECP-NST puede considerarse como una opción de tratamiento para las manifestaciones de la EP invalidantes, siempre y cuando la selección del paciente sea cuidadosa. (AU)

Introduction. Parkinson’s disease (PD) and schizophrenia can coexist. Antipsychotics block striatal D2 receptors, which inevitably aggravates the manifestations of PD.Case report. We report the case of a male patient with idiopathic Parkinson’s disease and schizophrenia, with poor tolerance to minimal doses of levodopa, who underwent a dramatic improvement after bilateral subthalamic deep brain stimulation (DBS-STN). DBS-STN was taken into consideration here, due to the severity of this particular case, as the only possible way to achieve motor improvement.Conclusions. The diagnosis of idiopathic PD was confirmed despite antidopaminergic treatment. DBS-STN can be considered a treatment option for disabling manifestations of PD, provided that a careful selection of patients is carried out. (AU)

Auditory cortex hyperconnectivity before rTMS is correlated with tinnitus improvement.

INTRODUCTION: Repetitive transcranial magnetic stimulation (rTMS) has been used as a potential treatment for tinnitus; however, its effectiveness is variable and unpredictable. We hypothesized that resting-state functional connectivity before rTMS may be correlated with rTMS treatment effectiveness. METHODS: We applied 1-Hz rTMS to the left primary auditory (A1) and dorsolateral prefrontal cortices (DLPFC) of 10 individuals with tinnitus and 10 age-matched controls. Resting-state functional magnetic resonance imaging (fMRI) studies were performed approximately one week before rTMS. Seed-based connectivity analyses were conducted for each individual, with seed regions as rTMS target areas. RESULTS: Compared to controls, the left superior temporal areas showed significantly increased positive connectivity with the left A1 and negative connectivity with the left DLPFC in the tinnitus group. The left frontoparietal and right cerebellar areas showed significantly increased negative connectivity with the left A1 and positive connectivity with the left DLPFC. Seed-based hyperconnectivity was correlated with tinnitus improvement (pre-rTMS vs. 2-week post-rTMS Tinnitus Handicap Inventory scores). Tinnitus improvement was significantly correlated with left A1 hyperconnectivity; however, no correlation was observed with left DLPFC connectivity. Positive rTMS outcomes were associated with significantly increased positive connectivity in bilateral superior temporal areas and significantly increased negative connectivity in bilateral frontal areas. CONCLUSIONS: Our results suggest that oversynchronisation of left A1 connectivity before rTMS of the left A1 and DLPFC is associated with treatment effectiveness.

Introducción: La estimulación magnética transcraneal repetitiva (EMTr) se ha utilizado como posible tratamiento para los acúfenos, aunque su efectividad es variable e impredecible. Planteamos la hipótesis de que existe una correlación entre la conectividad funcional en estado de reposo antes de aplicar EMTr y la efectividad de dicho tratamiento. Métodos: Aplicamos EMTr a 1 Hz sobre la corteza auditiva primaria (A1) y la corteza prefrontal dorsolateral (CPFDL) izquierdas de 10 pacientes con acúfenos y 10 controles del mismo rango de edad. Se realizaron estudios de resonancia magnética funcional (RMF) en estado de reposo de todos los pacientes aproximadamente una semana antes de la EMTr. En cada caso, se construyó un mapa de conectividad basado en las ROIs, en el que las ROIs eran las áreas que se tratarían con la EMTr. Resultados: La región temporal superior izquierda mostró una conectividad positiva significativamente mayor con el área A1 izquierda y mayor conectividad negativa con la CPFDL izquierda en los pacientes con acúfenos que en los controles. Además, las áreas frontoparietal izquierda y cerebelar derecha mostraron una conectividad negativa significativamente superior con el área A1 izquierda y mayor conectividad positiva con la CPFDL izquierda. La hiperconectividad de las ROIs se correlacionó con mejoría de los acúfenos según las puntuaciones pre-EMTr y 2 semanas post-EMTr en la escala Tinnitus Handicap Inventory. La mejoría de los acúfenos se correlacionó de manera significativa con la hiperconectividad del área A1 izquierda; sin embargo, no se encontró correlación con la conectividad de la CPFDL izquierda. El resultado favorable del tratamiento con EMTr se asocia con una mayor conectividad positiva en áreas temporales superiores de ambos hemisferios y con mayor conectividad negativa en áreas frontales bilaterales...(AU)

Neuroestimulación del nervio vago, hipocampal y de núcleos anteriores y centromedianos del tálamo en epilepsia temporal: revisión de la literatura / Neurostimulation of the vagus nerve, hippocampal and anterior and centromedian nuclei of the thalamus in temporal epilepsy: literature review

Introducción: En pacientes con epilepsia del lóbulo temporal refractarios que no son candidatos a cirugía, se debe considerar la estimulación eléctrica cerebral como una opción. Contenido: La estimulación eléctrica cerebral es la administración directa de pulsos eléctricos al tejido nervioso que permite modular un sustrato patológico, interrumpir la manifestación clínica de las crisis y reducir la gravedad de estas. Así, dada la importancia de estos tratamientos para los pacientes con epilepsia del lóbulo temporal refractaria, se hace una revisión de cuatro tipos de estimulación eléctrica. La primera, la del nervio vago, es una buena opción en crisis focales y crisis generalizadas o multifocales. La segunda, la del hipocampo, es más útil en pacientes no candidatos a lobectomía por riesgo de pérdida de memoria, con resonancia magnética normal o sin esclerosis mesial temporal. La tercera, la del núcleo anterior, es pertinente principalmente en pacientes con crisis focales, pero debe realizarse con precaución en pacientes con alto riesgo de cambios cognitivos, como los ancianos, o en los que presentan alteración del estado de ánimo basal, y, por último, la del núcleo centromediano se recomienda para el tratamiento crisis focales en el síndrome de Rasmussen y crisis tónico-clónicas en el síndrome de Lennox-Gastaut. Conclusiones: El interés por la estimulación eléctrica cerebral ha venido aumentando, al igual que las estructuras diana en las cuales se puede aplicar, debido a que es un tratamiento seguro y eficaz en pacientes con epilepsia del lóbulo temporal para controlar las crisis, pues disminuye la morbimortalidad y aumenta la calidad de vida.

Introduction: In patients with refractory temporal lobe epilepsy who are not candidates for surgery, electrical brain stimulation should be considered as another option. Contents: Electrical brain stimulation is the direct administration of electrical pulses to nerve tissue that modulates a pathological substrate, interrupts the clinical manifestation of seizures, and reduces their severity. Thus, given the importance of these treatments for patients with refractory temporal lobe epilepsy, four types of electrical stimulation are reviewed. The first, vagus nerve stimulation, is a good option in focal seizures and generalized or multifocal seizures. The second, hippocampal stimulation, is more useful in patients who are not candidates for lobectomy due to the risk of memory loss, with normal MRI or without mesial temporal sclerosis. The third, the anterior nucleus, is mainly in patients with focal seizures, but with caution in patients at high risk of cognitive changes such as the elderly, or in those with baseline mood disturbance and, finally, the centromedian nucleus is recommended for the treatment of focal seizures in Rasmussen's syndrome and tonic-clonic seizures in Lennox-Gastaut syndrome. Conclusions: the interest in brain electrical stimulation has been increasing as well as the target structures in which it can be applied because it is a safe and effective treatment in patients with temporal lobe epilepsy to control seizures, decreasing morbidity and mortality and increasing quality of life
