Consensus from the Brazilian Academy of Neurology for the diagnosis, genetic counseling, and use of disease-modifying therapies in 5q spinal muscular atrophy / Consenso da Academia Brasileira de Neurologia para diagnóstico, aconselhamento genético e uso de terapias modificadoras na atrofia muscular espinhal 5q

Abstract Spinal muscular atrophy linked to chromosome 5 (SMA-5q) is an autosomal recessive genetic disease caused by mutations in the SMN1. SMA-5q is characterized by progressive degeneration of the spinal cord and bulbar motor neurons, causing severe motor and respiratory impairment with reduced survival, especially in its more severe clinical forms. In recent years, highly effective disease-modifying therapies have emerged, either acting by regulating the splicing of exon 7 of the SMN2 gene or adding a copy of the SMN1 gene through gene therapy, providing a drastic change in the natural history of the disease. In this way, developing therapeutic guides and expert consensus becomes essential to direct the use of these therapies in clinical practice. This consensus, prepared by Brazilian experts, aimed to review the main available disease-modifying therapies, critically analyze the results of clinical studies, and provide recommendations for their use in clinical practice for patients with SMA-5q. This consensus also addresses aspects related to diagnosis, genetic counseling, and follow-up of patients under drug treatment. Thus, this consensus provides valuable information regarding the current management of SMA-5q, helping therapeutic decisions in clinical practice and promoting additional gains in outcomes.

Resumo Atrofia muscular espinhal ligada ao cromossomo 5 (AME-5q) é uma doença genética de herança autossômica recessiva causada por mutações no gene SMN1. A AME-5q cursa com degeneração progressiva dos motoneurônios medulares e bulbares, acarretando grave comprometimento motor e respiratório com redução da sobrevida, especialmente nas suas formas clínicas mais graves. Nos últimos anos, terapias modificadoras da doença altamente eficazes, ou que atuam regulando o splicing do exon 7 do gene SMN2 ou adicionando uma cópia do gene SMN1 via terapia gênica, têm surgido, proporcionando uma mudança drástica na história natural da doença. Dessa forma, o desenvolvimento de guias terapêuticos e de consensos de especialistas torna-se importante no sentido de direcionar o uso dessas terapias na prática clínica. Este consenso, preparado por especialistas brasileiros, teve como objetivos revisar as principais terapias modificadoras de doença disponíveis, analisar criticamente os resultados dos estudos clínicos dessas terapias e prover recomendações para seu uso na prática clínica para pacientes com AME-5q. Aspectos relativos ao diagnóstico, aconselhamento genético e seguimento dos pacientes em uso das terapias também são abordados nesse consenso. Assim, esse consenso promove valiosas informações a respeito do manejo atual da AME-5q auxiliando decisões terapêuticas na prática clínica e promovendo ganhos adicionais nos desfechos finais.

Incidence and risk factors of post dural puncture headache after spinal anesthesia in Tripoli Hospitals

Post Dural Puncture Headache (PDPH) remains a prominent clinical concern to the present day and common complication seen in the field of anesthesiology and pain medicine. Identification of such risk factors is a crucial step in the rational modification of anesthetic practice and evaluation of therapeutic interventions. This study was conducted to demonstrate the incidence and risk factors of PDPH in patients after spinal Anesthesia during three days' post operations at general hospital in Tripoli, Libya. In this study certain factors related to patient history, baseline clinical state or anesthetic technique might be associated with an increased risk for this side effect, so it was collected historical, physiologic, and technical data to determine their association with PDPH. Out of total of 100 patients distributed over 5 different hospitals admitted over a period (from November 2020 to April 2021) 27% of them have a PDPH, while 92.5% of cases with PDPH are females, that 55.6% of PDPH cases are between 20 and 25 years old, and this percentage getting smaller as patients get older, most of the operations were caesarean section, at a rate of 58%, followed by lower abdominal surgeries with 19% of cases, and orthopedic surgeries with 17% of cases, while the lowest percentage was for the Urologic surgeries. 55% of cases with PDPH are classified as (case I), and 44% of them are classified as (case II), 81.5% of PDPH cases used noncutting needles. In this study the PDPH remains the most problem in hospitalized patients after spinal Anesthesia at Tripoli hospitals can be caused by variety of risk factors, associated with ASA physical states, nonprofessional technique, the females are more common than males and the percentage increasing in early age group

Mechanism of Shikonin on spinal cord injury in rats based on TNFR/RIPK1 pathway / 中国骨伤

OBJECTIVE@#To explore the effect of shikonin on the recovery of nerve function after acute spinal cord injury(SCI) in rats.@*METHODS@#96 male Sprague-Dawley(SD)rats were divided into 4 groups randomly:sham operation group (Group A), sham operation+shikonin group (Group B), SCI+ DMSO(Group C), SCI+shikonin group (Group D).The acute SCI model of rats was made by clamp method in groups C and D . After subdural catheterization, no drug was given in group A. rats in groups B and D were injected with 100 mg·kg-1 of shikonin through catheter 30 min after modeling, and rats in group C were given with the same amount of DMSO, once a day until the time point of collection tissue. Basso-Beattie-Bresnahan(BBB) scores were performed on 8 rats in each group at 6, 12, and 3 d after moneling, and oblique plate tests were performed on 1, 3, 7 and 14 d after modeling, and then spinal cord tissues were collected. Eight rats were intraperitoneally injected with propidine iodide(PI) 1 h before sacrificed to detection PI positive cells at 24 h in each group. Eight rats were sacrificed in each group at 24 h after modeling, the spinal cord injury was observed by HE staining.The Nissl staining was used to observe survivor number of nerve cells. Western-blot technique was used to detect the expression levels of Bcl-2 protein and apoptosis related protein RIPK1.@*RESULTS@#After modeling, BBB scores were normal in group A and B, but in group C and D were significantly higher than those in group A and B. And the scores in group D were higher than those in group C in each time point (P<0.05). At 12 h after modeling, the PI red stained cells in group D were significantly reduced compared with that in group C, and the disintegration of neurons was alleviated(P<0.05). HE and Nissl staining showed nerve cells with normal morphology in group A and B at 24h after operation. The degree of SCI and the number of neuronal survival in group D were better than those in group C, the difference was statistically significant at 24h (P<0.05). The expression of Bcl-2 and RIPK1 proteins was very low in group A and B;The expression of RIPK1 was significantly increased in Group C and decreased in Group D, with a statistically significant difference (P<0.05);The expression of Bcl-2 protein in group D was significantly higher than that in group C (P<0.05).@*CONCLUSION@#Shikonin can alleviate the pathological changes after acute SCI in rats, improve the behavioral score, and promote the recovery of spinal nerve function. The specific mechanism may be related to the inhibition of TNFR/RIPK1 signaling pathway mediated necrotic apoptosis.

Effect of high-frequency repetitive transcranial magnetic stimulation in M1 region combined with dorsolateral prefrontal cortex on electroencephalogram θ frequency band amplitude of patients with neuropathic pain after spinal cord injury / 中国康复理论与实践

ObjectiveTo explore the efficacy of high-frequency repetitive transcranial magnetic stimulation (rTMS) in M1 region combined with dorsolateral prefrontal cortex (DLPFC) on electroencephalogram (EEG) θ frequency band amplitude of patients with neuropathic pain (NP) after spinal cord injury. MethodsFrom June, 2022 to June, 2023, 50 NP patients after SCI in Qingdao University Affiliated Hospital were included and divided into M1 region stimulation group (n = 25) and M1 region combined with DLPFC stimulation group (the combined stimulation group, n = 25). M1 region stimulation group received 10 Hz rTMS in the left M1 region, while the combined stimulation group received same stimulation in left M1 region combined with DLPFC, for three weeks. Before and after intervention, the pain was assessed with Short Form of McGill Pain Questionnaire (SF-MPQ), the depression and anxiety status were evaluated using Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA), and the EEG θ frequency band amplitude was recorded to detect the changes of brain electrophysiological activity. ResultsFour cases in M1 region stimulation group, and two cases in the combined stimulation group were dropped. After intervention, the total score of SF-MPQ and the scores of the subscales, the scores of HMMD and HAMA decreased in both groups (|t| > 2.523, P < 0.05). The EEG θ frequency band amplitude significantly reduced in the prefrontal and frontal regions in M1 region stimulation group (|t| > 5.243, P < 0.001), and it also significantly reduced in the prefrontal, frontal regions, central and parietal regions in the combined stimulation group (|t| > 4.630, P < 0.001). All the scores were lower (|t| > 2.270, Z = -1.973, P < 0.05), and the EEG θ frequency band amplitude in the prefrontal, frontal regions, central and parietal regions were lower (P < 0.05) in the combined stimulation group than in M1 region stimulation group. ConclusionHigh frequency rTMS is an effective analgesic method on NP after SCI, which can improve their depression and anxiety symptoms and reduce the EEG θ frequency band amplitude. Compared with M1 region rTMS stimulation, the combination of M1 region and DLPFC rTMS is more effective.

Obstacles and Facilitators in Daily Living Activities Among Persons with Spinal Cord Injury: A Systemic Review

@#Introduction: This systematic review aimed to investigate the level of participation, obstacles, and facilitator factors that influence activities of daily living among persons with spinal cord injury (SCI). Methods: A comprehensive search was conducted in four online databases, namely Google Scholar, PubMed, OT Seeker, and Cochrane Library covering the ten-years period from January 2012 to December 2022. Inclusion criteria encompassed original published studies in English focusing on daily activities, work, participation, obstacles, and facilitators in persons with SCI. Non-peer review sources (e.g., abstracts, grey literature, preprints), and studies unrelated to occupational therapy were excluded. The selected studies were assessed for quality using McMaster University Occupational Therapy Evidence-Based Practice critical review form. Results: Out of the 678 articles identified, ten studies were included after the screening, exploring participation in daily living activities, employment, return to work, leisure activities, family tasks, and community mobility among persons with SCI. Obstacles and facilitators influencing participation in activities of daily living were classified using the International Classification of Functioning, Disability, and Health (ICF) framework. This review highlighted that long-term participation is challenging for persons with SCI, affected by obstacles such as body functions, pain, low self-esteem, and environmental and social factors. Conclusion: The findings underscore the importance of adopting a multidisciplinary rehabilitation approach to enhance participation in daily activities for persons with SCI. Occupational therapy plays a significant role in improving participation levels among persons with SCI.

Situation-Specific Theory from Autonomic Dysreflexia Nursing Diagnosis Based on Roy's Adaptation Model

Introduction: Autonomic dysreflexia (AD) is a condition developed secondary to a spinal cord injury, which manifests with the loss of coordinated autonomic responses and cardiovascular control. For the care of the person, the nurse has the nursing diagnosis of AD, which allows the precise interpretation of the human responses of each individual. However, it is necessary to strengthen and update the diagnosis to the new disciplinary knowledge that evolved with nursing practice. For this, proposing a situation-specific theory is essential to explain the phenomenon of interest and guide practice. Objective: To construct a situation-specific theory for the nursing diagnosis of AD derived from the adaptation model of Sor Callista Roy. Materials and methods: Theoretical study developed in five stages: defining the approach to construct the theory, defining key concepts, developing a pictorial diagram, building propositions, and establishing causal relationships and evidence for practice. Results: The situation-specific theory included defining key concepts, developing a pictorial diagram, building propositions, and establishing causal relationships and evidence for practice. We described the concepts and their relationships through seven propositions and identified 19 ineffective behaviors and 43 environmental stimuli. Of them, 39 are focal, and four are contextual stimuli. Conclusions: This situation-specific theory offers a substantiated and comprehensive explanation of the human response to AD for supporting nursing care.

Lumbar safety triangle: comparative study of coronal and coronal oblique planes in 3.0-T magnetic resonance imaging / Triângulo de segurança lombar: estudo comparativo dos planos coronal e coronal oblíquo em ressonância magnética 3.0-T

Abstract Objective: To compare the measurements of the lumbar safety triangle (Kambin's triangle) and the invasion of the dorsal root ganglion in the triangle in coronal and coronal oblique planes. Materials and Methods: A cross-sectional study, in which 210 3.0-T magnetic resonance images of L2-L5 were analyzed in coronal and coronal oblique planes. Exams with lumbar spine anomalies were excluded. Demographic (sex and age) and radiological variables were recorded by a single evaluator. Results: Most sample was female (57.1%), mean age 45.5 ± 13.3 (18-98 years). The measurements average, as well as the areas, gradually increased from L2 to L5. The dorsal root ganglion invaded the triangle in all images. The safety triangle average area was smaller in the coronal oblique plane than in the coronal plane. Of the seven dimensions of safety triangle obtained for each level of the lumbar spine, six were significantly smaller in the coronal oblique plane than in the coronal plane. The only dimension that showed no difference was the smallest ganglion dimension. Conclusion: The dimensions and areas investigated were smaller in coronal oblique plane, especially the area (difference > 1 mm). The analysis of the triangular zone in this plane becomes important in the preoperative assessment of minimally invasive procedures.

The statistical analysis on the probabilities of dying showed that in a traumatic cervical event, patients with assisted mechanical ventilation, medical complications, injury severity level (ASIA A or B) who suffered a traffic accident had a higher risk of dying than those who were not in these groups. The level of social dependence of the group was between moderate and severe. Conclusions: population aging requires the development of specialized therapies, where the morphophysiological characteristics of this group are taken into account, which will allow better functional recovery and an adequate quality of life.

Estado actual de la cefalea postpunción meníngea en un hospital colombiano / Status of post-dural puncture headache in a Colombian hospital

Introducción: La cefalea postpunción meníngea (CPPM) posterior a la anestesia raquídea es una de las complicaciones más frecuentes asociadas a factores intrínsecos del paciente y de la técnica anestésica. Objetivo: Describir la frecuencia y los factores asociados con el desarrollo de la cefalea postpunción meníngea. Materiales y métodos: Serie retrospectiva de pacientes que ingresaron a un hospital de segundo nivel y se les confirmó el diagnóstico de cefalea secundaria a la anestesia raquídea. Resultados: Serie de 49 casos, 88 % de sexo femenino y 12 % de sexo masculino, con una edad media de 27,7 años. Los procedimientos quirúrgicos con desenlace de CPPM fueron: cirugías de ginecología y obstetricia (63 %), cirugías de urgencias de otras especialidades (28 %) y cirugías electivas (8 %). La técnica anestésica se realizó con agujas biseladas tipo Quincke calibre 25 gauge (G) en 14%, calibre 26 G 33 % y 27 G 53 %. El 51 % se realizó en posición de sedestación y el 49 % en decúbito lateral izquierdo. El 10% de los casos se manejó con parche hemático, en tanto que el antecedente de migraña se presentó en el 8 %. Discusión: En la actualidad, el uso de agujas con diseño de punta cónica es el estándar de oro, ya que permite obtener resultados confiables y disminuye complicaciones como la CPPM. Conclusión: La CPPM luego de una anestesia espinal se relacionó con factores como la edad (joven), el sexo (femenino) y el uso de agujas biseladas. Los otros factores de riesgo identificados fueron poco concluyentes, aunque no se pueden descartar, debido a la naturaleza de este estudio.

Introduction: Post dural puncture headache (PDPH) following spinal anesthesia is one of the most frequent complications associated with intrinsic patient and anesthetic technique factors. Objective: To describe the frequency and associated factors related to the development of PDPH. Materials and methods: Retrospective series of patients admitted to a second level hospital with a confirmed diagnosis of headache secondary to spinal anesthesia. Results: Series of 49 cases, 88 % female and 12 % male, mean age 27.7 years. The surgical procedures resulting in CPPM were gynecology and obstetrics surgeries 63 %, emergency surgeries of other specialties 28 % and elective surgeries 8 %. The anesthetic technique was performed with beveled needles Quincke type 25 gauge (G) in 14 %, 26 G gauge 33% and 27 G 53 %. In the seated position 51 % and in the left lateral decubitus position 49% were performed. A blood patch was used in 10 % of the cases and a history of migraine was present in 8 %. Discussion: The use of needles with conical tip design is currently the gold standard, they give reliable results and reduce complications such as PDPH. Conclusion: PDPH after spinal anesthesia was related to factors such as age (young), sex (female) and the use of traumatic needles. The other risk factors identified were inconclusive, although they cannot be ruled out due to the nature of this study.

Rider sitting position widens lumbar intervertebral distance: a prospective observational study

Abstract Background: Reduced lumbar lordosis may make the process of identifying the intervertebral distance easier. The primary aim of this study was to measure the L3-L4 intervertebral space in the same patients undergoing spinal anesthesia in three different sitting positions, including the classic sitting position (CSP), hamstring stretch position (HSP) and rider sitting position (RSP). The secondary aim was to compare ultrasonographic measurements of the depth of the ligamentum flavum and intrathecal space in these three defined positions. Methods: This study is a single-blinded, prospective, randomized study. Ninety patients were included in final analysis. the patients were positioned on the operating table in three different positions to perform ultrasonographic measurements of the spinal canal. The intervertebral distance (IVD), the distance between the skin and the ligamentum flavum (DBSLF) and the intrathecal space (IS) were measured in the L3 -L4 intervertebral space in three different positions. Results: The RSP produced the largest mean distance between the spinous processes. The RSP yielded a significantly larger IVD than did the CSP (p < 0.001) and HSP (p < 0.001). The DBSP was larger in the CSP than in the HSP (p = 0.001). The DBSLF was significantly larger in the RSP than in the HSP (p = 0.009). Conclusions: Positioning the patient in the RSP significantly increased the intervertebral distance between L3 -L4 vertebrae compared to the CSP and HSP, suggesting easier performance of lumbar neuraxial block.

Effectiveness and safety of ultra-low-dose spinal anesthesia versus perineal blocks in hemorroidectomy and anal fistula surgery: a randomized controlled trial

Abstract Background: Ultra-low-dose Spinal Anesthesia (SA) is the practice of employing minimal doses of intrathecal agents so that only the roots that supply a specific area are anesthetized. The aim of this study was to compare the effectiveness and safety of ultra-low-dose spinal anesthesia with that of Perineal Blocks (PB). Methods: A two-arm, parallel, double-blind randomized controlled trial comparing two anesthetic techniques (SA and PB) for hemorrhoidectomy and anal fistula surgery was performed. The primary outcomes were postoperative pain, complementation and/or conversion of anesthesia, and hemodynamic changes. Results: Fifty-nine patients were included in the final analysis. The mean pain values were similar in the first 48 h in both groups (p > 0.05). The individuals allocated to the SA group did not need anesthetic complementation; however, those in the PB group required it considerably (SA group, 0% vs. PB group, 25%; p = 0.005). Hemodynamic changes were more pronounced after PB: during all surgical times, the PB group showed lower MAP values and higher HR values (p < 0.05). Postoperative urinary retention rates were similar between both groups (SA group 0% vs. PB group 3.1%, p = 0.354). Conclusion: SA and PB are similarly effective in pain control during the first 48 h after hemorrhoidec-tomy and anal fistula surgery. Although surgical time was shorter among patients in the PB group, the SA technique may be preferable as it avoids the need for additional anesthesia. Furthermore, the group that received perineal blocks was under sedation with a considerable dose of propofol.

Accidente fatal debido al uso de ácido tranexámico vía intratecal. Presentación de caso

Los errores en la administración de medicamentos durante la anestesia continúan siendo una causa importante de morbimortalidad, incluso en países industrializados. El ácido tranexámico es un agente antifibrinolítico indicado para reducir el sangramiento perioperatorio en varios procederes quirúrgicos. Se presenta el caso de una gestante de 23 años con 37,2 semanas de gestación, en el Baringo Country Referral Hospital, de Kenia. Durante la administración de la anestesia raquídea en la cesárea, se le aplicó de forma accidental este medicamento por vía intratecal. La paciente comenzó con mioclonías de miembros inferiores, convulsiones tonicoclónicas, y llegó a la parada cardiorrespiratoria. Se ingresó en Cuidados Intensivos, donde se identificaron signos indirectos de muerte encefálica, y falleció al sexto día de su ingreso. La literatura reporta que la mortalidad por este accidente anestésico en embarazadas es muy elevada, debido a altas concentraciones del medicamento en el líquido cefalorraquídeo.

Errors in the drugs administration during anesthesia continue to be a major cause of morbidity and mortality, even in industrialized countries. Tranexamic acid is an antifibrinolytic agent indicated to reduce perioperative bleeding in several surgical procedures. The case of a 23-years-old pregnant woman with 32.7 weeks of pregnancy treated at the Baringo Referral Hospital, in Kenya, is presented. During the administration of spinal anesthesia in the cesarean section, this medication was accidentally applied intrathecally. The patient began with myoclonus of the lower limbs, tonic-clonic seizures, and reached cardio-respiratory arrest. She was admitted to Intensive Care, where indirect signs of brain death were identified, and she died on the six day after admission. The literature reports that mortality for this anesthetic accident is very high, due to high concentration of the drug in the cerebrospinal fluid.

Brazilian version of the CHOP INTEND scale: cross-cultural adaptation and validation / Versão brasileira da escala CHOP INTEND: adaptação transcultural e validação

Abstract Background Spinal muscular atrophy (SMA) is a rare genetic disease that causes progressive muscle weakness and impacts motor function. The type I is the most severe presentation and affects infants before 6 months old. In addition, the instruments available for assessing motor function have limitations when applied to infants with neuromuscular diseases and significant muscle weakness. Objective To translate, cross-culturally adapt, and validate the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) to Brazilian Portuguese. Methods The present study comprised the translation, synthesis of translations, backtranslation, consolidation by a committee of experts, and test of the final version of the CHOP INTEND in 13 patients with SMA type I. We also assessed the content validity and reliability of the translated version. Results The scale was translated considering semantic, structural, idiomatic, and cultural aspects. All agreement rates were > 0.8, the overall content validity index of the instrument was 0.98, and inter-rater reliability using the intraclass correlation coefficient was 0.998. Conclusion The Brazilian version of the CHOP INTEND met semantic and technical equivalence criteria with the original version and was valid and reliable for patients with SMA type I.

El síndrome de compresión medular es una urgencia neuroquirúrgica debido a que un diagnóstico precoz y un tratamiento temprano podría revertir las incapacitantes secuelas ocasionadas por esta enfermedad. Las causas de este síndrome pueden ser traumática, metastásica, infecciosa y vascular (hematomas). La etiología infecciosa no es frecuente y el principal germen involucrado suele ser Staphylococcus aureus. A continuación presentamos el caso de una paciente de 58 años con síndrome de compresión medular de etiología infecciosa quien fue ingresada en el Servicio de Clínica Médica del Centro Médico Nacional.

Spinal cord compression syndrome is a neurosurgical emergency because early diagnosis and early treatment could reverse the disabling consequences caused by this disease. The causes of this syndrome can be traumatic, metastatic, infectious, and vascular (hematomas). Infectious etiology is not frequent and the main germ involved is usually Staphylococcus aureus. Below we present the case of a 58-year-old patient with spinal cord compression syndrome of infectious etiology who was admitted to the Medical Clinic Service of the National Medical Center.

Surgical outcome of spinal schwannoma and neurofibroma

SUMMARY OBJECTIVE: The aim of this study was to evaluate the outcome and surgical complications in patients with spinal schwannoma or neurofibroma surgically treated at the Hospital das Clínicas of the State University of Campinas. METHODS: This was a retrospective cohort study, using medical records of patients operated between 2011 and 2021. The sample distribution was verified using the Kolmogorov-Smirnov test. The dynamics between qualitative variables were assessed using Fisher's exact test. We used means analysis to assess patient improvement based on Frankel scores. RESULTS: A total of 16 patients were evaluated, of whom 56.25% (9) were men and 43.75% (7) were women. There were 13 (81.25%) patients with schwannomas and 3 (18.75%) with neurofibromas. Patients with deficits had neurological improvement, such as walking or with at least Frankel D or E after surgery. Laminectomy, performed in 8 patients (50%), and laminoplasty, used in 9 patients (56.25%), were the main techniques. CONCLUSION: The surgical approach was proved to be an effective and safe alternative to the treatment of these tumors, with neurological improvement and minor surgical complications.
