Trauma raquimedular silente / Trauma raquimedular silente

El traumatismo raquimedular se define como el trauma que afecta cualquier nivel de las estructuras de la columna vertebral (osteoligamentosas, cartilaginosas, musculares, vasculares, meníngeas, radiculares y medulares). Los pacientes son en su mayoría jóvenes, víctimas de accidentes o violencia. Los costos de su tratamiento inmediato y a largo plazo son elevados. Se reporta un caso de trauma raquimedular en un adolescente, cuyo examen físico demostró normalidad neurológica; sin embargo, en los exámenes de imagen se evidenció triple fractura vertebral toráxica (T6, T7 y T8), que fue corregida mediante cirugía, seguida de rehabilitación física; la recuperación fue completa y no quedaron secuelas. La normalidad neurológica luego de injuria espinal no descarta un daño medular, por lo que el cuidado inmediato y la evaluación completa de estos pacientes son parte fundamental del protocolo de su atención.

Spinal cord trauma is defined as the trauma that affects all levels of the structures of the spine (osteo, ligament, cartilaginous, muscle, vascular, meningeal, root and spinal cord). The patients are mostly young people, victims of accidents or violence. Immediate treatment and long-term costs are high. We report a case of spinal cord trauma in a teenager, whose physical exam was neurologically normal. However, the image exams showed triple spinal thoracic fracture (T6, T7 and T8), which was corrected by surgery, followed by physical rehabilitation; the recovery was complete and the patient had not sequelae. Neurological normality after spinal injury does not rule out a spinal cord damage; that is why immediate care and complete evaluation of these patients are an essential part of the protocol of their health attention.

Factores fisiológicos y psicológicos que influyen en la rehabilitación de las personas con trauma raquimedular / Physiological and psychological factors in rehabilitation of persons with traumatic of spinal cord

Resumen La rehabilitación integral de las personas con trauma raquimedular requiere integrar lo físico, emocional y social, es necesario indagar como estos factores se interrelacionan y afectan su calidad de vida. El objetivo fue determinar la interrelación de los factores fisiológicos y psicológicos en la rehabilitación integral de las personas con trauma raquimedular a partir de la Teoría de los Síntomas Desagradables de Elizabeth Lenz. Estudio descriptivo transversal, con 51 personas. Las variables independientes fueron clasificación ASIA, nivel de la lesión y sexo; las variables dependientes los factores fisiológicos y psicológicos. Se aplico análisis univariado y la prueba t para identificar las diferencias estadísticamente significativas. La disrreflexia autonómica, las disfunciones vesicales e intestinales generan estados de depresión y expresión de ira especialmente en los hombres, es muy importante brindar soporte para el cuidado de estos factores durante la rehabilitación integral.

Abstract The comprehensive rehabilitation of people with spinal cord trauma takes into account the person as a whole being in the physical, emotional and social sense; therefore, it is necessary to investigate how these factors interact and affect their quality of life. The objective was determining the interrelation between the physiological and psychological factors on rehabilitation of people with spinal cord trauma from the theory of unpleasant symptoms Elizabeth Lenz. A transversal descriptive study, with 51 people. The independent variables were ASIA classification, the level of injury, and gender; the dependent variables were the physiological and psychological factors. A univariate analysis, the t- test was applied to identify statistically significant differences. The autonomic dysreflexia and both bladder as well as bowel dysfunction, are symptoms that generate states of depression and expression of anger, and are more evident in men. The support is required in the care of these factors during la integral rehabilitation.

Características clínicas y demográficas de pacientes con trauma raquimedular Experiencia de seis años / Clinical and demographic characteristics of patients with spinal cord injury Six years experience

Introducción: el trauma raquimedular (TRM) es una entidad potencialmente catastrófica y la información acerca de las características del TRM penetrante relacionadas con violencia, particularmente las heridas por arma de fuego es escasa. Diseño del estudio: estudio de cohorte retrospectiva. Objetivos: determinar las características clínicas y demográficas de la población con TRM atendidas en un hospital de tercer nivel de Medellín. Métodos: revisamos las historias clínicas de los pacientes admitidos con diagnóstico de TRM entre enero de 2005 y diciembre de 2010. Se recolectaron datos con respecto a estancia hospitalaria y en la unidad de cuidados intensivos (UCI), el estado vital y la recuperación neurológica al egreso. Resultados: tuvimos 68 casos de TRM con una frecuencia de 12 casos por 1000 pacientes admitidos a la UCI. La edad media fue de 28 años y 91% fueron del sexo masculino. La principal causa de TRM fue herida por arma de fuego (57%) seguido por accidentes de tránsito (32%). La estancia media de UCI fueron seis días, 56% de los pacientes requirió ventilación mecánica y 37% requirió traqueostomía. El nivel de lesión medular más frecuente fue cervical. La mortalidad hospitalaria fue de 21%, todos estaban con ventilación mecánica y entre más alto fue el nivel de lesión medular mayor era la mortalidad. Conclusiones: nuestra investigación muestra que la población principalmente afectada por el TRM en nuestro medio son los jóvenes y la mortalidad, así como la estancia, complicaciones infecciosas y discapacidad tienen relación directa con el nivel de lesión medular.

Introduction: spinal cord injury (SCI) is a potentially catastrophic entity and information about the characteristics of pervasive SCI related to violence, particularly gunshot wounds, is scarce. Study Design: Retrospective cohort study. Objectives: to determine the clinical and demographic characteristics of the population with SCI attended in a tertiary hospital in Medellin. Methods: The medical records of patients admitted with a diagnosis of SCI between January 2005 and December 2010 were reviewed. Data regarding stay in the hospital and intensive care unit (ICU), vital status and neurological recovery at hospital discharge were collected. Results: there were 68 cases of SCI at a rate of 12 cases per 1000 patients admitted to the ICU. The average age was 28 years and 91% were male. The main cause of SCI was gunshot wounds (57%) followed by traffic accidents (32%). The mean ICU stay was six days, 56% of patients required mechanical ventilation and 37% required tracheostomy. The most common level of spinal cord injury was cervical. Hospital mortality was 21%, all were mechanically ventilated and the higher the level of spinal cord injury, the greater was the mortality. Conclusions: our research shows that people mainly affected by the SCI in our environment are young and mortality, as well as stay, infectious complications and disability are directly related to the level of spinal cord injury.

Fatores de risco hereditários e adquiridos na coagulação: impacto no desenvolvimento de eventos tromboembólicos em pacientes com lesão medular causada por trauma raquimedular / Hereditary and acquired clinical risk factors in the coagulation: impact in the development of thromboembolic events in patients with spinal injury caused by spinal cord injury

Objetivo: Avaliar o impacto de fatores de risco no desenvolvimento de eventos tromboembólicos em pacientes com lesão medular. Métodos: Estudo observacional, prospectivo e cruzado. Pacientes elegíveis (n=100) tinham lesão medular por trauma raquimedular e mais de 18 anos. O grau de lesão sensorial e motora foi avaliado com base na escala ASIA (ASIA Impairment Scale - AIS). Amostras de sangue foram coletadas para exames de coagulação, hemogramas, análises bioquímicas e laboratoriais. Exames de ultrassonografia foram realizados nos sistemas venosos superficial e profundo dos membros inferiores. Experimentos de PCR em tempo real foram realizados com o intuito de investigar mutações nos genes da protrombina (G20210A) e do fator V de Leiden (G1691A). Resultados: O principal achado deste estudo foi a maior ocorrência de Trombose Venosa Profunda (TVP) em pacientes com fator V de Leiden e hiperhomocisteinemia. Não houve associação entre Lesão Medular por TVP, Tromboembolismo Venoso (TEV) e trombofilia. Não houve também relação com lúpus anticoagulante e anti-cardiolipina. Conclusões: Houve importante diferença na incidência de TVP em pacientes com Lesão Medular, tanto aguda quanto crônica (após um ano da lesão). A investigação de trombofilia deve ter como base os fatores clínicos, fatores de risco para TVP e história familiar de trombose

Objective: Evaluate the impact of risk factors in the development of thromboembolic events in patients with spinal cord injury. Design: Observational, prospective and cross study. Eligible patients (n=100) had spinal injury (SI) by spinal cord injury (SCI), older than 18 years of age. The degree of motor and sensory lesion was evaluated based on ASIA Impairment Scale (AIS). Blood samples were collected for coagulation exams, hemogram, laboratory and biochemical analyses. Ultrasonography analyzes were performed from deep and superficial venous systems of lower limbs. Quantitative real-time PCR experiments were performed in order to investigate mutations in the prothrombin (G20210A) and Leiden factor V (G1691A) genes. Results: The main finding of this study was the higher occurrence of Deep Venous Thromboembolism (DVT) in patients with Leiden factor V and hyper homocysteinemia. There was no association between SI for DVT, venous thromboembolism (VT) and thrombophilia. Also, there was no relation between lupus anticoagulant and anti-cardiolipin. Conclusions: There is an important difference in the incidence of DVT in patients with SI by acute SCI and after 1 year. The conduct of the investigation for thrombophilia should be based on clinical factors, risk factors for DVT and family history of thrombosis

Llegándose a concluir que el paciente con trauma raquimedular es un varón joven económicamente activo, con estancia hospitalaria prolongada, de evolución favorable pues responde al tratamiento conservador; con riesgo de incapacidad por paraplejia.

The study of traumatic spinal cord injuries, is vitally important because it affects the economically active population, harming among others, the economic growth of the families involved, therefore, the study seeks to examine what are the epidemiological characteristics of spinal cord injuries, evaluating the prevalence according sex, age group, etiology, sequelae, hospital management, complications and morbidity and mortality among other variables, through a multicenter comparative descriptive retrospective, including neurosurgical centers for reference of Valparaiso-Chile and Bolivia-Cochabamba. We reviewed medical records of 372 patients with final diagnosis of spinal cord injury, of the period January to June 2002-2010, and the results were as follows: We obtained an average of 3.72 + 0.12 cases per month: the age group most affected was 20-29 years in Valparaiso and 30-39 years in Cochabamba (28.8 percent, SD + 2.2). The male is most affected (66.9 percent, SD + 3.7) being the most common cause from great heights in Cochabamba and the activity of the boobies in the sea in Valparaiso (36.9 percent, SD + 4.3), the average hospital stay was 20.29 + 19.4 days in Valparaiso and 22.16 +11.5 days in Cochabamba. The conservative treatment was the most used and only 12 + 2.16 percent underwent surgery, 97 + 3.3 percent had a favorable outcome, the most common sequel was the paraplegia in 6.7 + 3.2 percent of the cases, and mortality was 6.3 percent in Valparaiso and 3 percent in Cochabamba. The authors conclude that patients with spinal cord injury are most frequent in the young male economically active, with prolonged hospital stay, because of favorable response to conservative treatment, with risk of disability due to paraplegia.

Nuevas estrategias en el tratamiento del trauma raquimedular: actualización bibliográfica / New strategies in treatment of spinal cord injury: literature update

Better understanding of spinal cord injury pathophysiology has allowed the development of new areas of investigation, focused in reducing the injury and stimulating cord regeneration. The preliminary results of these investigations have generated great expectation in the scientific world, together with ambiguous information for patients with these injuries. In this article, we present a review of the available literature in this area, describing several non-pharmacological interventions, together with new drugs, immune therapies to block processes that inhibit cord regeneration and the renowned cell therapy. After evaluating the available articles included in this review, we observed a progress towards an increased efficacy of these treatments, but with limitations due to methodological flaws in the study protocols, which do not allow us to make applicability recommendations of them in humans.

Los recientes avances en el entendimiento de la fisiopatología del traumatismo raquimedular, han permitido el desarrollo de investigación enfocada en intervenciones orientadas a disminuir la lesión y estimular la regeneración medular. El entusiasmo por este nuevo conocimiento ha generado expectativa en el mundo científico co e información ambigua en los pacientes con este tipo de lesiones. En este trabajo revisamos la literatura reciente y la que se está llevando a cabo a este respecto, encontrando la descripción de algunas intervenciones no farmacológicas diferentes a la cirugía, nuevos medicamentos, terapias de bloqueo inmunológico de procesos que inhiben la regeneración medular y la reconocida terapia celular. Al evaluar los trabajos incluidos en esta revisión, observamos un avance hacia el aumento de la efectividad de los tratamientos pero con la limitación debida a las falencias metodológicas en la investigación que impiden hacer recomendaciones de aplicabilidad de los mismos en humanos.

Spinal cord injury: epidemiologycal study of 386 cases with emphasis on those patients admitted more than four hours after the trauma / Trauma raquimedular: estudo epidemiológico de 386 casos com ênfase para aqueles pacientes admitidos após quatro horas do trauma

We studied 386 cases of spinal cord injury to analyze the follow up of the patients admitted most of the time more than four hours, the majority of the injuries happening far from the attending health service and first specialized care received long after the accident. This is a clinical study based on data collected during hospitalization of the patients, operated or not, in a Brazilian public health service. The lesion mainly seen was fracture and dislocation, isolated or on multiple levels, and the most important clinical complications were due to respiratory failure and hypotension, especially because 73.8 percent were from outside and they were admitted more then four hours after the trauma. The mortality rate was 11.9 percent, but just 2.1 percent had undergone a surgery. The complications resulted in major risk of death when the trauma was at the cervical level and the patients were over 50 years old, especially when admitted more than four hours after the trauma. We emphasize the importance of the first health care concerning the clinical treatment, aiming to reduce the mortality rate.

Estudamos 386 casos de trauma raquimedular, observando a evolução dos pacientes admitidos na maioria das vezes após quatro horas do trauma, a maioria procedente de lugar distante do serviço de saúde. Trata-se de um estudo clínico baseado em dados coletados durante a hospitalização, de pacientes operados ou não, em serviço de saúde pública no Brasil. Na maioria das vezes a lesão principal foi fratura-luxação, isolada ou em múltiplos níveis, e as complicações clínicas mais importantes foram devido à insuficiência respiratória e hipotensão, especialmente porque 73.8 por cento dos casos eram de lugares distantes, tendo sido admitidos mais de quatro horas após o trauma. A taxa de mortalidade foi 11,9 por cento, sendo 2,1 por cento em pós-operatório. As complicações resultaram em maior risco de morte quando o trauma foi ao nível cervical, idade acima de 50 anos, especialmente aqueles admitidos com mais de quatro horas. Enfatizamos a importância do primeiro atendimento na admissão, sobretudo para as alterações respiratórias e hemodinâmicas, objetivando reduzir a mortalidade.
