ABSTRACT

INTRODUCTION: Degenerative lumbar disease (DLE) is a spectrum of pathological changes from disc degeneration, herniated disc, spondylolisthesis and lumbar canal stenosis. The pain associated with it is multifactorial. Muscle cramps are among the most frequent causes. The relationship between muscle degeneration and DLE has already been studied in the past in multiple studies, highlighting the one carried out by Kjaer & cols. OBJECTIVE: to determine the prevalence and severity of fatty degeneration in mutifidus spinae, and to study its relationship with clinical and radiographic factors. MATERIAL AND METHODS: observational and analytical study. Patients diagnosed with: herniated disc, lumbar canal stenosis or degenerative scoliosis were included. They were classified according to the Kjaer scale for paraspinal fatty infiltration in one of three groups. Clinical variables were analyzed: age, smoking, obesity, the presence of axial pain, temporality of pain, severity expressed with a visual analog scale (VAS); and radiographic: number of diseased segments, involved segments, diagnostic imaging and the presence of spondylolisthesis. RESULTS: 56 patients with an average age of 52.5 years (16 to 80) with a predominance of females with 62.5% were included. The diagnoses were nonspecific low back pain (1.8%), herniated disc (42.9%), narrow lumbar duct (46.4%) and lumbar duct with degenerative scoliosis deformity (8.9%). The distribution among the three groups described by Kjaer was as follows: 44.6% were classified with a fat infiltration score of 2. In groups 1 and 0, 39.3% and 16.1% were classified respectively. The variables significantly related to greater fat infiltration were: age > 60 years, diagnoses of lumbar canal stenosis and herniated disc; obesity, spondylolisthesis < 2 vertebral segments involved. Axial pain and VAS > 8 points were not related to greater muscle degeneration. CONCLUSIONS: fatty infiltration is present in all patients with some of the forms of DLE. Most patients > 60 years of age with advanced degenerative processes have a greater severity of infiltration. Other related variables are: obesity, spondylolisthesis and disease of < 2 vertebral segments. There is no relationship between a higher percentage of fatty infiltration and axial pain or higher VAS scores.


INTRODUCCIÓN: la enfermedad lumbar degenerativa (ELD) es un espectro de cambios patológicos desde la degeneración discal, la hernia discal, la espondilolistesis y el conducto lumbar estrecho. El dolor que se le asocia es multifactorial. Los espasmos musculares son de las causas más frecuentes. La relación que guarda la degeneración muscular y la ELD ya ha sido estudiada en múltiples trabajos, destacando el realizado por Kjaer y colaboradores. OBJETIVO: determinar la prevalencia y severidad de la degeneración grasa en el mutifidus spinae, y estudiar su relación con variables clínicas y radiográficas. MATERIAL Y MÉTODOS: estudio observacional y analítico. Se incluyeron pacientes diagnosticados con: hernia discal, conducto lumbar estrecho o escoliosis degenerativa. Se clasificaron de acuerdo con escala de Kjaer para infiltración grasa paraespinal en alguno de tres grupos. Se analizaron variables clínicas: edad, tabaquismo, obesidad, presencia de dolor tipo axial, temporalidad del dolor, severidad del dolor expresada con escala visual análoga (EVA); y radiográficas: número de segmento enfermos, segmentos involucrados, diagnóstico por imagen y presencia de espondilolistesis. RESULTADOS: se incluyeron 56 pacientes con edad promedio de 52.5 años (rango 16 a 80) con predominio del sexo femenino (62.5%). Los diagnósticos fueron lumbalgia inespecífica (1.8%), hernia discal (42.9%), conducto lumbar estrecho (46.4%) y conducto lumbar con deformidad en escoliosis degenerativa (8.9%). La distribución entre los tres grupos descritos por Kjaer fue la siguiente: 44.6% fueron clasificados con un puntaje de infiltración grasa de 2. En los grupos 1 y 0, se clasificaron 39.3 y 16.1%, respectivamente. Las variables relacionadas con mayor infiltración grasa fueron: edad > 60 años, diagnósticos de conducto lumbar estrecho y hernia discal; obesidad, espondilolistesis < 2 segmentos vertebrales involucrados. El dolor mecánico y EVA > 8 puntos no se relacionaron con mayor degeneración muscular. CONCLUSIONES: la infiltración grasa está presente en todos los pacientes con alguna de las formas de ELD. La mayoría de los pacientes > 60 años con procesos degenerativos avanzados tienen mayor severidad de infiltración. Otras variables relacionadas son: obesidad, espondilolistesis y enfermedad < 2 segmentos vertebrales. No hay relación entre mayor porcentaje de infiltración grasa y dolor axial o puntajes más altos de dolor.

ABSTRACT

INTRODUCTION: Chronic subdural haematoma (CSDH) represents a clinical challenge due to its high recurrence rate. Endovascular middle meningeal artery embolisation (eMMAE) has emerged as an alternative for those patients presenting health problems or multiple recurrences of CSDH. Despite several encouraging reports, the safety profile, indications, and limitations of the technique are not clearly established. DEVELOPMENT: This study aimed to evaluate the current evidence on eMMAE in patients with CSDH. We performed a systematic review of the literature, following the PRISMA guidelines. Our search yielded a total of 6 studies, in which a total of 164 patients with CSDH underwent eMMAE. The recurrence rate across all studies was 6.7%, and complications occurred in up to 6% of patients. CONCLUSIONS: eMMAE is a feasible technique for treating CSDH, with a relatively low recurrence rate and an acceptable rate of complications. Further prospective and randomised studies are needed to formally establish a clear profile of the safety and effectiveness of the technique.

ABSTRACT

Introducción: Dadas las altas tasas de recurrencia, el hematoma subdural crónico (HSDC) es una condición que supone un reto para el clínico. La embolización endovascular de la arteria meníngea media (EeAMM) ha surgido como una alternativa para aquellos pacientes con problemas de salud o con varias recurrencias de su HSDC. A pesar de la publicación de algunos artículos prometedores referentes a esta técnica, el perfil de seguridad, las indicaciones y las limitaciones no están claramente establecidas.DesarrolloNuestro objetivo es evaluar la evidencia actual sobre la EeAMM en el HSDC. Se realizó una revisión sistemática de la literatura según las guías PRISMA. Nuestra búsqueda arrojó un total de 6 estudios, en los que 164 pacientes con HSDC se sometieron a EeAMM. La tasa de recurrencia entre todos los estudios fue del 6,7% y se produjeron complicaciones en hasta el 6% de los pacientes.ConclusiónLa EeAMM es una técnica factible en el tratamiento del HSDC con una tasa de recurrencia relativamente baja y tasas aceptables de complicaciones. Se necesitan más estudios prospectivos y aleatorizados para establecer formalmente un perfil de seguridad claro y su efectividad. (AU)

ABSTRACT

INTRODUCTION: Extradural anterior clinoidectomy (eAC) is key to expose the paraclinoid region. Several authors have pointed limitations of performing an eAC through a supraorbital craniotomy. In this article, we aim to provide educational material and discuss the technical nuances to successfully perform an eAC throughout a modification of the supraorbital approach, the extradural extended eyebrow approach (xEBA+eAC). METHODS: Four embalmed heads were used for anatomic dissection and perform the xEBA+eAC. Additionally, one head was used for a video demonstration of the surgical approach. RESULTS: The anterior clinoid process was successfully removed, and the ophthalmic artery and paraclinoid region were exposed in all specimens. Drilling the sphenoid wing until exposing the meningo-orbital band and further interdural dissection are vital steps to expose the anterior clinoid process. Removal of the anterior clinoid process can be simplified in 3 osteotomies, including the optic canal unroofing, detachment from the lateral pillar, and drilling of the optic strut. Sectioning of the distal dural ring facilitates the mobilization of the internal carotid artery and the surgical exposure of the ophthalmic artery. CONCLUSIONS: xEBA+eAC is a technically feasible approach that provides exposure to the paraclinoid region, along with anterior and middle cranial fossa.

ABSTRACT

INTRODUCTION: Multiple myeloma represents 1% of all cancers and 10% of hematological cancers. Up to 80-90% of cases will have skeletal involvement and the spine is the most frequently involved site. Any intervention must be aimed to improve the patients functional prognosis and will impact their quality of life. OBJECTIVE: To describe the clinical presentation of vertebral destruction syndrome due to multiple myeloma and to present the management algorithm used for the study and decision-making in treatment. MATERIAL AND METHODS: Study design: Retrospective cross-sectional. A search was made in the hospitals clinical file in search of patients with a histological diagnosis of multiple myeloma attended by the Spinal Surgery Service. Clinical characteristics of the initial presentation were obtained such as: presence of pain, ASIA scale and it was categorized according to the Durie-Salmon classification at diagnosis; the levels involved and type of surgery were described. RESULTS: The study included ten patients with an average age of 61.4 years, 70% were male subjects. All patients were approach according to the modified protocol for vertebral destruction syndrome and fluoroscopy-guided percutaneous biopsy. Most had pain at diagnosis, after neurologic examination only 30% were classified as ASIA A. Most of the patients were staged III according to Durie Salomon. The most frequently vertebral segment involved was thoracic. In only one patient more than two vertebrae were involved. After diagnosis of multiple myeloma, nine patients were managed according to a NOMS framework. In the majority they were treated with fusion by posterior approach, six of them were augmented with vertebroplasty. Only one patient of the total, was treated with vertebroplasty alone. CONCLUSIONS: The use of systematized management algorithms will allow better decisions to be made in conjunction with a multidisciplinary group for the care of multiple myeloma with vertebral involvement.


INTRODUCCIÓN: El mieloma múltiple representa 1% de todos los tipos de cáncer y 10% de los cánceres hematológicos. Hasta en 80-90% de los casos se involucrará el sistema esquelético, siendo la columna el sitio más frecuentemente afectado. Cualquier intervención planeada deberá ser dirigida a mejorar el pronóstico funcional del paciente e impactará en su calidad de vida. OBJETIVO: Describir la presentación clínica del síndrome de destrucción vertebral por mieloma múltiple y presentar el algoritmo de manejo empleado para el estudio y la toma de decisiones en el tratamiento. MATERIAL Y MÉTODOS: Diseño de estudio: Retrospectivo, transversal. Se realizó una búsqueda en el archivo clínico del hospital en búsqueda de pacientes con diagnóstico histológico de mieloma múltiple atendidos por el Servicio de Cirugía de Columna. Se obtuvieron características clínicas de la presentación inicial como: presencia de dolor, escala de ASIA y se categorizó de acuerdo con la clasificación de Durie-Salmon al diagnóstico; se describen los niveles involucrados y tipo de cirugía. RESULTADOS: El estudio incluyó 10 pacientes con una edad promedio de 61.4 años, 70% de los cuales fueron varones. Todos los pacientes se abordaron de acuerdo al protocolo de síndrome de destrucción vertebral y con biopsia percutánea guiada por fluoroscopía. La mayoría de los pacientes tenían dolor al diagnóstico, tras la exploración neurológica sólo el 30% fueron clasificados como ASIA A. La mayoría de los pacientes se estadificaron como III de acuerdo con Durie-Salmon. El segmento vertebral más comúnmente afectado fue el torácico. En sólo un paciente se involucraba más de dos vértebras. Tras el diagnóstico de mieloma múltiple, nueve pacientes fueron manejados de acuerdo con el marco de trabajo NOMS. La mayoría fueron tratados con fusión por un abordaje posterior, seis de ellos con aumentación con vertebroplastía. Sólo un paciente del total, fue tratado sólo con vertebroplastía. CONCLUSIONES: El empleo de algoritmos de tratamiento sistematizado permitirá la toma de mejores decisiones en conjunto con un grupo multidisciplinario para el tratamiento de mieloma múltiple con afección vertebral.

ABSTRACT

La encefalopatía crónica postraumática es una enfermedad neurodegenerativa fruto de la acumulación de numerosos traumatismos craneoencefálicos, para la cual no existe un diagnóstico premórtem definitivo ni un tratamiento específico. Entre los factores de riesgo asociados con la encefalopatía crónica postraumática se encuentran: la exposición a deportes de contacto, la presencia de la apolipoproteína E4 y la edad avanzada. Histopatológicamente, aunque comparte ciertas características con la enfermedad de Alzheimer, tiene una presentación más específica (depósito de proteína tau fosforilada en forma de ovillos neurofibrilares, asociados a acúmulo de elementos del neuropilo, acompañados en ocasiones de placas de beta-amiloide). Clínicamente se caracteriza por un curso lento que se inicia con síntomas cognitivos leves y emocionales, y progresa hacia la aparición de síntomas parkinsonianos y demencia. A pesar de que existen elementos diagnósticos prometedores, no son, actualmente, una realidad, y la clave en el manejo de esta enfermedad es la prevención y la detección precoz de sus primeros síntomas (AU)


Chronic traumatic encephalopathy is a neurodegenerative disease produced by accumulated minor traumatic brain injuries; no definitive premortem diagnosis and no treatments are available for chronic traumatic encephalopathy. Risk factors associated with chronic traumatic encephalopathy include playing contact sports, presence of the apolipoprotein E4, and old age. Although it shares certain histopathological findings with Alzheimer disease, chronic traumatic encephalopathy has a more specific presentation (hyperphosphorylated tau protein deposited as neurofibrillary tangles, associated with neuropil threads and sometimes with beta-amyloid plaques). Its clinical presentation is insidious; patients show mild cognitive and emotional symptoms before progressing to parkinsonian motor signs and finally dementia. Results from new experimental diagnostic tools are promising, but these tools are not yet available. The mainstay of managing this disease is prevention and early detection of its first symptoms (AU)
