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.

Clinical Study of Modified Shenqi Pill （肾气丸） Plus Tongdu Tiaoshen Acupuncture （通督调神针刺） for Neurogenic Bladder After Spinal Cord Injury of Kidney-Yang Deficiency Syndrome / 中医杂志

ObjectiveTo observe the clinical efficacy of modified Shenqi Pill （肾气丸） plus Tongdu Tiaoshen Acupuncture （通督调神针刺） in the treatment of neurogenic bladder after spinal cord injury of kidney-yang deficiency syndrome. MethodsForty-six patients were randomly divided into 23 cases each in the control group and the treatment group. Both groups were given conventional treatment， i.e. oral methylcobalamin tablets （0.5 mg each time， 3 times a day） and paraplegic conventional acupuncture （once a day， 6 consecutive days a week）. The control group was given simple bladder function rehabilitation training on the basis of the conventional treatment； and the treatment group was given modified Shenqi Pill orally （1 dose a day， 150 ml each time， taken warmly in morning and evening） and Tongdu Tiaoshen Acupuncture （once a day， 6 consecutive days per week） in addition to what were given to the control group. The treatment course lasted for 4 weeks. The 24 h urination frequency， 24 h urine leakage frequency， 24 h single urine volume， bladder residual urine volume， international lower urinary tract symptom （LUTS） score， traditional Chinese medicine （TCM） syndrome score were compared between the two groups， and clinical effectiveness and TCM syndrome effectiveness were compared between the two groups after treatment. ResultsTwenty patients in each group were finally analyzed in this study. The number of 24 h urination， the number of 24 h urine leakage， bladder residual urine volume， LUTS score， and the TCM syndrome scores decreased after treatment in both groups， and the 24 h single urine volume increased （P＜0.01）； and much more improvement was found of each index in the treatment group than in the control group （P＜0.05 or P＜0.01）. The total clinical effectiveness and TCM syndrome effectiveness in the treatment group was 85.00% （17/20） respectively， which were statistically significantly higher than 45.00% （the total clinical effectiveness， 9/20） and 60.00% （TCM syndrome effectiveness， 12/20） in the control group （P＜0.01）. ConclusionModified Shenqi Pill plus Tongdu Tiaoshen Acupuncture can signi-ficantly improve the clinical symptoms of neurogenic bladder patients after spinal cord injury of kidney-yang deficiency syndrome， having better effectiveness than simple bladder function rehabilitation training， and its mechanism may be related to the improvement of the injured nerve function innervating the bladder.

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.

Resumo Objetivo: Comparar as medidas do triângulo de segurança lombar (triângulo de Kambin) e invasão do gânglio da raiz dorsal no triângulo nas incidências coronal e coronal oblíqua. Materiais e Métodos: Estudo transversal, em que foram analisadas 210 imagens de ressonância magnética 3.0-T de L2-L5 nos planos coronal e coronal oblíquo. Foram excluídos exames com anomalias da coluna lombar. Variáveis demográficas (sexo e idade) e radiológicas foram registradas por um único avaliador. Resultados: A maioria da amostra era do sexo feminino (57,1%), com idade média de 45,5 ± 13,3 (18-98 anos). A média das medidas, assim como as áreas, aumentaram gradativamente de L2 a L5. O gânglio da raiz dorsal invadiu o triângulo em todas as imagens. A área média do triângulo de segurança foi menor na incidência coronal oblíqua do que na incidência coronal. Das sete dimensões do triângulo de segurança obtidas para cada nível da coluna lombar, seis foram significativamente menores no plano coronal oblíquo do que no plano coronal. Única dimensão que não apresentou diferença foi a menor dimensão do gânglio. Conclusão: As dimensões e áreas investigadas foram menores na incidência coronal oblíqua, especialmente a área (diferença > 1 mm). A análise da zona triangular nesta incidência torna-se importante na avaliação pré-operatória de procedimentos minimamente invasivos.

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.

Vulnerabilidad del adulto mayor con lesión cervical traumática

Fundamento: los adultos mayores sufren caídas que producen complicaciones traumáticas, dentro de estas se encuentra el trauma raquimedular que produce una alta tasa de discapacidad y mortalidad. Objetivo: exponer factores pronósticos que repercuten en el adulto mayor con lesión espinal cervical traumática. Métodos: se realizó un estudio de corte transversal sobre 42 pacientes geriátricos diagnosticados con trauma raquimedular cervical atendidos en Camagüey, desde 2019 hasta el 2022. Se analizaron las variables siguientes: datos demográficos, tipo de accidente, nivel de la lesión, complicaciones médicas, terapia utilizada y como variable dependiente la mortalidad. Resultados: se observó un predominio de los pacientes entre 60 a 74 años. El análisis estadístico sobre las probabilidades de fallecer mostró que ante un evento cervical traumático los pacientes con ventilación mecánica asistida, complicaciones médicas, nivel de severidad de la lesión (ASIA A o B) que sufrieron un accidente de tránsito tuvieron mayor riesgo de morir que los que no se encontraban en estos grupos. El nivel de dependencia social del grupo estuvo entre moderado y severo. Conclusiones: el envejecimiento poblacional requiere del desarrollo de terapias especializadas, donde se tomen en cuenta las características morfofisiológicas de este grupo que permitirá mejor recuperación funcional y una calidad de vida adecuada.

Objective to set out the prognostic factors that affect the elderly with traumatic cervical spinal injury. Methods: a cross-sectional study was carried out with 42 geriatric patients diagnosed with spinal cord trauma treated in Camagüey, from 2019 to 2022. The research consisted of a stage for the collection of demographic data, the type of accident, the level of injury, medical complications, the therapy used and another where the statistical processing was carried out where the mortality variable was considered as dependent. Results: a predominance of patients between 60 and 74 years of age was observed. 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.

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.

Prognostic predictive model for PONV in cesarean delivery

Introduction: Apfel simplified risk score for postoperative nausea and vomiting (PONV) has shown to be useful in anesthesia; however, since it has not been calibrated in regional anesthesia or in pregnant patients, its use in cesarean section is limited. Objective: To develop a prognostic predictive model for postoperative nausea and vomiting in pregnant patients undergoing cesarean section under spinal anesthesia. Methods: In a cohort of 703 term pregnant patients scheduled of cesarean section, 15 variables were prospectively assessed, to design a prognostic predictive model for the development of postoperative nausea and vomiting. A logistic regression analysis was used to construct the model and its calibration and discrimination were based on the Hosmer-Lemeshow test, the calibration curves, and C statistic. Additionally, the internal calibration was performed with the Bootstrap resampling method. Results: Postoperative nausea and vomiting were experienced by 27% of the patients during the first six hours after surgery. The model included as prognostic variables the development of intraoperative nausea and vomiting, age under 28 years, a history of PONV, the mother's BMI and the weight of the newborn baby. The model showed an adequate calibration (x2: 4.65 p: 0.5888), though a low discrimination (Statistic C = 0.68). Conclusions: A prognostic predictive model was created for the development of PONV in cesarean section. This model was used to build a prognostic scale for the classification of patients into risk groups.

Introducción: La escala de riesgo simplificada de Apfel para náuseas y vómito posoperatorio (NVPO) ha mostrado utilidad en anestesia; sin embargo, al no haber sido calibrada en anestesia regional o en pacientes embarazadas, su utilidad en cesárea es limitado. Objetivo: Desarrollar un modelo de predicción pronóstica para náuseas y vómito posoperatorios en pacientes embarazadas, llevadas a cesárea bajo anestesia espinal. Métodos: En una cohorte de 703 pacientes con embarazo a término programadas para cesárea, se evaluaron 15 variables de forma prospectiva para construir un modelo de predicción pronóstica para el desarrollo de náuseas y vómito posoperatorio. Se utilizó el análisis de regresión logística para la construcción del modelo y se calculó su calibración y discriminación con la prueba de Hosmer-Lemeshow, las curvas de calibración y el estadístico C. Además, se realizó la calibración interna con el método de remuestreo Bootstrap. Resultados: Las náuseas y vómito posoperatorio se presentaron en el 27% de las pacientes durante las primeras seis horas después de la cirugía. El modelo incluyó como variables pro-nósticas el desarrollo de náuseas y vómito en el intraoperatorio, edad menor de 28 años, antecedentes de NVPO, índice de masa corporal (IMC) de la madre y el peso del recién nacido. El modelo mostró una adecuada calibración (x2: 4,65 p: 0,5888), aunque una baja discriminación (Estadístico C = 0,68). Conclusiones: Se construyó un modelo de predicción pronóstica para el desarrollo de NVPO en cirugía cesárea, y con este se construyó una escala pronóstica que permite clasificar a las pacientes por grupos de riesgo.

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.

Recentemente, a terapia por ondas de choque extracorpóreas (TOCE) mostraram-se ser uma promissora tecnologia não invasiva para neuromodulação e recuperação funcional devido a melhora em brotamento neuronal, neuroproteção, controle de neuroplasticidade e reorganização neuronal, além de atuar em fatores de neurogênese. Objetivo: Descrever um caso que usa TOCE como um adjuvante na reabilitação de trauma medular. Relato de caso: LPS, 25 anos, estudante de medicina, sofreu uma queda de altura indeterminada com fratura de C5 e lesão medular associada a trauma cranioencefálico. Na fase aguda, ele se recuperou adequadamente, tendo sido submetido a descompressão e fixação de coluna e hospitalizado por 5 meses devido a disautonomias e infecções urinárias. Após esse período, ele iniciou um programa de reabilitação intensiva para tetraplegia espástica com classificação inicial segundo o ASIA (American Spinal Injury Association) nível C5 motor e C6 sensório. O tratamento incluiu 10 sessões de TOCE, realizadas com Duolith SD1 (Storz Medical, Suíça) com uma densidade de energia de 0,25mJ/mm², 5 cm e 3 cm de profundidade de foco, 2000 pulsos aplicados na linha média de coluna níveis C5 a T1 e 2000 pulsos a 5 cm de profundidade aplicados em região plantar bilateral. Bloqueio com toxina botulínica e fenol foram realizados com resposta parcial apesar da dose otimizada de baclofeno.

Recently, extracorporeal shockwaves (ESWT) have shown as a promising non-invasive technology for neuromodulation and functional recovery, due to improving neuronal budding, neuroprotection, control of neuroplasticity and neuronal reorganization, in addition to acting on neurogenesis factors. Objective: To describe a case that uses ESWT as an adjuvant to the rehabilitation of spinal cord trauma. Case Report: LPS, 25 years old, medical student, suffered a fall from an undetermined height with C5 fracture and spinal cord injury, associated with a cranioencephalic trauma. In the acute phase, he was rescued properly, performed decompression and spinal cord fixation and remained hospitalized for 5 months due to dysautonomia and urinary infections. After this period, he started an intensive in-patient rehabilitation program for spastic tetraplegia with initial classification according to ASIA C5 (motor) and C6 (sensory). The treatment included 10 sessions of ESWT, made with Duolith SD1 (Storz Medical, Switzerland) with an Energy flux density 0,25 mJ/mm2, at 5cm and 3cm depth focus, 2000 pulses each over the spinal cord at the midline of levels from C5 to T1, and 2000 pulses at 5cm depth focus applied at plantar region bilaterally.

Condicionantes para la participación laboral de las personas con discapacidad por lesión medular atendidas en un instituto especializado de rehabilitación

Objetivo : Determinar los factores condicionantes para la participación laboral de las personas con discapacidad por lesión medular de un instituto especializado de rehabilitación. Material y métodos : Estudio observacional, retrospectivo y relacional; se incluyeron 224 pacientes con lesión medular del Departamento de Investigación, Docencia, y Atención en Ayuda al Tratamiento del Servicio de Rehabilitación Profesional que fueron atendidos en el periodo 2016 al 2019. Se recolectaron variables clínicas, sociodemográficas y contextuales; y la actividad económica antes y después de la lesión. Resultados : El 65 % de pacientes fueron del sexo masculino, de edad media de 38,61 ± 13,33; según el nivel de lesión medular el 85,3% de pacientes tenía paraplejia, el 62,5% con grado de lesión en la escala ASIA A; el tiempo de evolución fue de más de 1 año 30,4%, estado civil soltero 52,2%, de procedencia Lima y provincias el 51,3%, con grado de instrucción de secundaria 50,9%, nivel socioeconómico de pobreza extrema en 61%. Se encontró diferencia significativa entre la participación laboral antes de la LM y el sexo (p<0,01) y la condición laboral (p<0,0069). La participación laboral después de la LM tuvo una diferencia significativa con el nivel socioeconómico (p<0.005) y el grado de lesión en la escala ASIA (p<0,014). El análisis de regresión logística mostró que el único factor asociado con la participación laboral fue el tiempo transcurrido de la lesión medular (p=0,039; OR=19,9). Conclusiones : Los pacientes con LM con menores ingresos económicos ubicados en grupos de pobreza pobre extremo y no extremo tuvieron mayor participación laboral; así como los que tuvieron un mayor grado de lesión en la escala ASIA. Asimismo, el único factor predictor de la participación laboral fue el tiempo transcurrido desde la lesión.

SUMMARY Objective : To determine the conditioning factors for labor participation in persons with disability due to spine lesions attended at a specialized rehabilitation center. Methods : A retrospective observational study was carried out at the Departamento de Investigación, Docencia, y Atención en Ayuda al Tratamiento del Servicio de Rehabilitación Profesional from 2016 to 2019, 224 patients were evaluated. Clinical, sociodemographic and contextual variables were collected as well as economic activity before and after the trauma. Results : 65% of patients were males; mean age was 38.61 ± 13.33; 85.3% had paraplegia and 63.5% had a lesion grade A on the ASIA scale; duration of illness was higher than one year in 30.4%; 52.2% were single; 51.3% come from provinces of Peru; 50.9% had secondary school level and 61% lived in extreme poverty. A significative difference for labor participation was found between sex (p<0.01) and labor condition (p<0.014) before the spinal lesion. Labor participation after the spinal lesion correlated with socioeconomic level (p<0.005) and the degree of the lesion based on the ASIA scale (p<0.014). The logistic regression analysis found that only duration of illness correlated with labor participation (p=0.039; OR=19.9). Conclusions : Patients with spinal lesions who lived in extreme poverty had higher labor participation as well as those with higher scores in the ASIA scale. The only predicting factor for labor participation was duration of illness.

Comparison of two different doses of hyperbaric bupivacaine for intracavitary radiotherapy in patients with carcinoma cervix ? A randomized control trial

Background: Subarachnoid block has been used for intracavitary radiotherapy (ICRT) for carcinoma cervix, but the literature on the appropriate dose of local anesthetic required to achieve the desired effect is lacking. We compared two different intrathecal doses of 0.5% hyperbaric bupivacaine (1.2 and 1.5 mL) for providing optimal surgical conditions and readiness to discharge in patients undergoing ICRT for carcinoma cervix. Materials and Methods: This prospective double?blind study was done in 80 patients undergoing ICRT. The patients were randomized into two groups (Groups I and II) to receive 1.2 and 1.5 mL of intrathecal hyperbaric bupivacaine, respectively, for ICRT. The level of sensory achieved, the patient satisfaction score, radiation oncologist score, time to L5 regression, and time to motor recovery (walking unaided) were assessed. Statistical Analysis Used: The data were analyzed using SPSS 20 for Windows (IBM, Chicago, IL, USA). Results: The time taken for the block to regress to L5 (Group I: 134.6 � 32.4 minutes vs. Group II: 143.2 � 43.0 minutes, P = 0.31) were comparable. However, the mean time for walking unaided (Group I: 220.87 � 47.12 minutes versus Group II: 247.00 � 49.83 minutes, P = 0.032) after the subarachnoid block was significantly less in Group I. The patient satisfaction with the procedure and overall satisfaction of the radiation oncologists regarding the operating condition were comparable in both the groups. Conclusions: Hence, a 1.2 mL dose of intrathecal hyperbaric bupivacaine for ICRT provides optimal surgical conditions with hemodynamic stability and ensures the early discharge of the patient.

The Effects Between Spinal and General Anesthesia for Pre-Eclamptic Mothers Underwent Caesarean Delivery in a Tertiary Care Hospital- A Comparative Study

Background: Preeclampsia is a multisystem disorder characterized by new onset of hypertension systolic blood pressure ?140 mmHg and/or diastolic blood pressure ?90 mmHg and proteinuria >300 mg/24 h arising after 20 weeks of gestation in a previously normotensive woman and associated with significant maternal and neonatal morbidity and mortality worldwide. Women with preeclampsia have an increased rate of cesarean section consequent upon the high incidence of intrauterine growth restriction, fetal distress, and prematurity. The aim of this study was to determine and compare maternal & neonatal outcome among pre-eclamptic women following caesarian delivery under general and spinal anesthesia. Material & Methods: This was a comparative observational study and was conducted in the Department of Anesthesiology of Holy Family red crescent Medical College Hospital, Dhaka, Bangladesh during the period from February,2020 to February,2023. In this study we included 250 preeclamptic women undergoing cesarean delivery. The patients were randomly divided into two groups – GA group (Patients who were given general anesthesia) & SA group (Patients who were given spinal anesthesia). Results: In total 250 patients from both the groups completed the study. In our study we found majority (44.8%) of our patients were aged 28-32 years. The mean age was 27.13 ± 3.76 years. Majority (62.8% ) of our patients were cases of emergency caesarean delivery & 37.2% were elective caesarean delivery classes. Most of the students (41.2%) used magnesium sulfate. Intraoperative systolic BP, diastolic BP was significantly lower in SA group than GA group. We found headache, vomiting, fever and wound gaping, postpartum hemorrhage & lower respiratory tract infection was significantly higher in GA group. On contrary, hypotension & pulmonary edema was higher in SA group. Apgar score at 1st, 5th & 10th minutes was significantly higher in GA group than SA group. In GA group, neonatal mortality at 48 h was 10.4% whereas it was 4.8% in SA group. Conclusion: In our study, we found intra-operative blood pressure and pulse rate was observed significantly higher in GA group than SA. Severe preeclamptic mothers receiving general anesthesia and their babies required more critical care support. Maternal as well as neonatal mortality was significantly higher with general anesthesia. Therefore, spinal anesthesia is a safer alternative to general anesthesia among women with severe preeclampsia following caesarean delivery with less postoperative morbidity and mortality.

A Comparative Analysis Between Spinal and General Anesthesia for Orthopedic Surgery

Background: Many surgeries can be performed with spinal anesthesia (SA) or general anesthesia (GA). However, there are only limited and confounding data available regarding costs and anesthesia-related times. Hip or knee replacement are common orthopedic surgeries that can be performed using SA or GA without differences regarding mortality or morbidity. Observational studies have suggested that spinal anesthesia may be associated with lower risks of death, delirium and major medical complications and with shorter lengths of stay in the hospital than general anesthesia. The aim of this study was to assess and compare the effects of spinal versus general anesthesia on postoperative outcomes in patients undergoing orthopedic surgery. Material & Methods: This was a comparative observational study and was conducted in the Department of Anesthesiology of Holy Family red crescent Medical College Hospital, Dhaka, Bangladesh during the period from March,2021 to March,2023. In this study we included 200 patients undergoing orthopedic surgery. The patients were randomly divided into two groups – Group A (Patients who were given general anesthesia) & Group B (Patients who were given spinal anesthesia). Results: In total 200 patients from both the groups completed the study. In our study we found majority (44.5%) of our patients were aged 60-69 years and most of our patients were female (56%) compared to male (44%).The mean age of our patients was 61.73 ± 7.92 years. The mean BMI was 31.67±3.24 kg/m.2Among all patients ,48% had mild systemic disease and followed by 31.5% had severe systemic disease. Majority (43.5%) of our patients had hypertension, 31% had diabetes. Vomiting was found 47% in group A on contrary only 23% had vomiting in spinal group. We found the mean anesthesia induction time was significantly higher in spinal group. Anesthesia time was lower in spinal group while PACU time was higher in group B. Time duration of surgery was significantly lower in spinal group. After 24 hours, spinal group showed less pain score than general anesthesia group. Conclusion: In our study, we found that SA is associated with less fixed and variable costs and lower postoperative pain scores during the stay in the PACU. Therefore, SA is a more reasonable alternative to GA in the immediate postoperative period for patients undergoing hip or knee replacement. When compared to general anaesthesia, spinal anaesthesia provides better operating circumstances, better postoperative pain control, and faster postoperative recovery.
