Epilepsia en el paciente oncológico: prevención primaria e importancia en la selección del paciente de alto riesgo / Epilepsy in cancer patients: primary prevention and the importance of high-risk patient screening

Introducción: La epilepsia en el paciente oncológico presenta una prevalencia del 13%, especialmente elevada en pacientes con tumores cerebrales, así como una mayor morbimortalidad respecto de la epilepsia no tumoral. Sus mecanismos fisiopatógenos son diferenciadores, e incluyen la distorsión de la arquitectura cortical y la alteración del microambiente molecular tumoral y peritumoral favorecedor de glutamato. A pesar de ello, existe evidencia científica escasa e inconsistente acerca de aspectos fundamentales, como la profilaxis primaria postoperatoria, el perfil farmacológico idóneo o el tiempo de retirada de fármacos anticrisis tras la libertad de éstas. Desarrollo: Características como el bajo grado tumoral, el número/tamaño de las lesiones corticales, la localización (frontal, cortical/subcortical o área elocuente), las crisis tempranas y las alteraciones moleculares, como mutación IDH1/2, son factores favorecedores para la aparición de crisis. Dentro del tratamiento, la cirugía aportará citorreducción y control de crisis por escisión del área epileptógena, con libertad de crisis incapacitantes del 75-90%. Aunque sigue siendo un tema controvertido, el uso postoperatorio de fármacos anticrisis está contraindicado por las principales sociedades científicas por la escasa evidencia y el amplio espectro de efectos secundarios. Sin embargo, se emplean frecuentemente en la práctica clínica diaria. Conclusiones: Todo ello nos obliga a establecer un grupo de pacientes de ‘alto riesgo’ de crisis postoperatorias, que precisará seleccionar el fármaco anticrisis idóneo en prevención primaria, con una vía de administración que facilite un rápido efecto de acción y una farmacocinética que evite el metabolismo hepático y la inducción de CYP450 para conseguir un menor número de interacciones con quimioterápicos, corticoides y radioterapia. A pesar de ello, se describen tasas de farmacorresistencia del 20-40% y recidiva del 25-29%.(AU)

Introduction: Epilepsy in cancer patients has a prevalence of 13%, and is especially high in patients with brain tumours, with a higher morbidity and mortality rate compared to non-tumour-related epilepsy. Its physiopathogenic mechanisms are distinct and include distortion of the cortical architecture and alteration of the glutamate-enhancing tumoural and peritumoural molecular microenvironment. Nevertheless, there is scarce and inconsistent scientific evidence on some fundamental aspects, such as primary post-operative prophylaxis, the ideal pharmacological profile or the withdrawal time of antiseizure drugs after their release. Development: Characteristics such as low tumour grade, number/size of cortical lesions, location (frontal, cortical/subcortical or eloquent area), early seizures and molecular alterations, such as IDH1/2 mutation, are factors that favour the occurrence of seizures. Within the treatment, surgery will provide cytoreduction and seizure control by excision of the epileptogenic area, with 75-90% freedom from disabling seizures. Although still a controversial issue, the post-operative use of antiseizure drugs is contraindicated by the main scientific societies due to the scarce evidence and the wide spectrum of side effects. However, they are frequently used in daily clinical practice. Conclusions: All this forces us to establish a group of patients at ‘high risk’ of postoperative seizures, who will need to select the ideal antiseizure drug for primary prevention, with a route of administration that facilitates a rapid action effect and pharmacokinetics that prevents hepatic metabolism and CYP450 induction to achieve a lower number of interactions with chemotherapy, corticosteroids and radiotherapy. Despite this, drug resistance rates of 20-40% and relapse rates of 25-29% have been reported.(AU)

Identificación de los factores que influyen en el retraso intrahospitalario del inicio de trombólisis intravenosa en el ictus agudo en un hospital terciario / Factors associated with in-hospital delays in treating acute stroke with intravenous thrombolysis in a tertiary centre

Objetivo: Identificar los factores que influyen en el tiempo puerta-aguja (tiempo P-A) en la administración de trombólisis intravenosa (TIV) en un hospital terciario para diseñar futuras estrategias que acorten los tiempos. Métodos: Estudio retrospectivo de pacientes tratados con TIV entre 2009 y 2012. Analizamos la relación entre el tiempo P-A y los siguientes factores: edad, sexo, antecedentes personales, tiempo inicio-puerta, activación de código ictus extrahospitalario (CIE), glucemia y presión arterial basal, NIHSS basal, realización de angio-TC o estudio neurosonológico previo, hora de llegada al hospital, día de la semana y año del ictus. Resultados: Hubo un total de 239 pacientes tratados. Tiempos de actuación en min (mediana [rango intercuartílico]): tiempo inicio-puerta 84 (60-120); tiempo puerta-TC 17 (13-24,75) tiempo TC-aguja 34 (26-47); tiempo puerta-aguja 52 (43-70); tiempo inicio-aguja 145 (120-180). El tiempo P-A fue significativamente menor con la activación del CIE: 51 vs. 72 (p = 0,008), y mayor con la realización de angio-TC: 59 vs. 48,5 (p = 0,004) y con tiempo inicio-puerta < 90 min: 58 vs. 48 (p = 0,003). En el análisis de regresión lineal múltiple 2 factores redujeron significativamente el tiempo P-A: la activación de CIE (reducción=26,3%; p < 0,001) y el tiempo inicio-puerta (por cada 30 min de tiempo inicio-puerta, el tiempo P-A se acortó 4,7 min; p = 0,02). Por el contrario realizar una angio-TC aumentó un 13,4% el tiempo P-A (p = 0,03). Los demás factores no influyeron significativamente en el tiempo P-A. Conclusiones: La realización de angio-TC y el «efecto de las 3 h» son 2 factores que retrasan el inicio de la TIV en nuestro hospital. Por el contrario el CIE reduce claramente los tiempos P-A. Los resultados de este estudio nos han permitido identificar qué factores retrasan nuestra actuación y servirán en un futuro para intentar disminuir los tiempos P-A en nuestro hospital

Objective: This study aims to determine which factors are associated with delays in door-to needle (DTN) time in our hospital. This will help us design future strategies to shorten time to treatment with intravenous thrombolysis (IVT). Methods: Retrospective analysis of a prospective cohort of patients with ischaemic stroke treated with IVT in our hospital between 2009 and 2012. We analysed the relationship between DTN time and the following variables: age, sex, personal medical history, onset-to-door time, pre-hospital stroke code activation, blood pressure and blood glucose level, National Institutes of Health Stroke Scale (NIHSS), computed tomography angiography (CTA) and/or doppler/duplex ultrasound (DUS) performed before IVT, time to hospital arrival, and day of the week and year of stroke. Results: Our hospital treated 239 patients. Median time to treatment in minutes (IQR): onset-to-door, 84 (60-120); door-to-CT, 17 (13-24.75); CT-to needle, 34 (26-47); door-to-needle, 52 (43-70); onset-to-needle, 145 (120-180). Door-to-needle time was significantly shorter when code stroke was activated, at 51 vs. 72 min (P = 0.008), and longer when CTA was performed, at 59 vs. 48.5 min (P = 0.004); it was also longer with an onset-to-door time < 90 min, at 58 vs. 48 min (P = 0.003). The multivariate linear regression analysis detected 2 factors affecting DTN: code stroke activation (26.3% reduction; P < 0.001) and onset-to-door time (every 30 min of onset-to-door delay corresponded to a 4.7min increase in DTN time [P = 0.02]). On the other hand, CTA resulted in a 13.4% increase in DTN (P = 0.03). No other factors had a significant influence on door-to-needle time. Conclusions: This study enabled us to identify CTA and the «3-hour effect» as the 2 factors that delay IVT in our hospital. In contrast, activating code stroke clearly reduces DTN. This information will be useful in our future attempts to reduce door-to-needle times

Hematoma espinal epidural espontáneo: estudio retrospectivo de una serie de 13 casos / Spontaneous spinal epidural haematoma: A retrospective study of a series of 13 cases

Introducción: El hematoma espinal epidural espontáneo (HEEE) tiene una incidencia estimada de un caso por millón de habitantes al año. Se considera espontáneo cuando no se logra relacionar ninguna causa de forma directa con su aparición. Objetivo: Describir una muestra de pacientes con HEEE y analizar las variables relacionadas con el pronóstico funcional del mismo. Pacientes y métodos: Estudio retrospectivo de pacientes diagnosticados de HEEE en nuestro centro entre 2001 y 2013. Resultados: Trece pacientes, 7 varones, con edad media de 71 años. El 62% presentaba hipertensión arterial (HTA) y el 54% utilizaba anticoagulantes orales, teniendo una razón normalizada internacional > 3 el 57% de ellos. La presentación clínica más frecuente fue dolor en columna vertebral (85%). El 92% asoció déficit neurológico en forma de síndrome sensitivo-motor (70%), motor puro (15%) o sensitivo puro (7%). Cinco pacientes recibieron tratamiento quirúrgico y 8 fueron tratados de forma conservadora. Al año, 3 de los pacientes tratados de forma quirúrgica y 4 de los de manejo conservador tenían una puntuación igual o menor de 2 en la Escala Rankin Modificada. Se observó peor pronóstico en pacientes anticoagulados, en hematomas de mayor extensión, en hematomas localizados en región lumbar y cuando el compromiso motor inicial era mayor. Conclusiones: La edad avanzada, la HTA y la anticoagulación son los principales factores asociados con el HEEE. La presentación típica consiste en dolor en la columna vertebral seguido de déficit motor. En pacientes con déficits motores establecidos, el tratamiento quirúrgico dentro de las primeras 24 h parece ser la mejor opción terapéutica

Introduction: Spontaneous spinal epidural haematoma (SSEH) has an estimated incidence of one per million inhabitants. It is classified as spontaneous when no identifiable cause can be linked to its onset. Objective: To describe a sample of patients with SSEH and analyse variables related to its functional prognosis. Patients and methods: Retrospective study carried out in patients diagnosed with SSEH between 2001 and 2013 in our hospital. Results: We included 13 subjects (7 men) with a mean age of 71 years. Of the total, 62% had hypertension and 54% were treated with oral anticoagulants; of the latter, 57% had an International Normalised Ratio above 3. The most frequent manifestation was spinal column pain (85%). Nearly all subjects presented an associated neurological deficit, whether sensory-motor (70%), pure motor (15%), or pure sensory (7%). Five patients underwent surgical treatment and 8 had conservative treatment. After one year, 3 of the patients treated surgically and 4 of those on conservative treatment had a score of 2 or lower on the modified Rankin Scale. Poorer prognosis was observed in patients with anticoagulant therapy, large haematomas, location in the lumbar region, and more pronounced motor disability at onset. Conclusions: Old age, hypertension, and anticoagulant therapy are the main risk factors for SSEH. The typical presentation consists of back pain with subsequent motor deficit. In patients with established motor symptoms, surgical treatment within the first 24 hours seems to be the best option

Labor asistencial del equipo de guardia de neurología en un hospital terciario de Madrid: análisis prospectivo durante un año / Workload of on-call emergency room neurologists in a Spanish tertiary care centre. A one-year prospective study

Introducción: El envejecimiento poblacional, el aumento en la demanda asistencial y la instauración de tratamientos avanzados para el ictus agudo han originado que las urgencias neurológicas crezcan en número y complejidad. A pesar de esto, muchos centros hospitalarios de España carecen de guardias específicas de Neurología. Métodos: Estudio prospectivo durante un año (agosto 2010-julio 2011), que describe la labor asistencial del equipo de guardia de Neurología del Hospital terciario Gregorio Marañón de Madrid. Se recogieron las características sociodemográficas, las principales afecciones, las pruebas diagnósticas y el flujo de los pacientes atendidos, utilizando un registro diario mediante una base de datos informatizada. Los resultados fueron comparados con la asistencia médica general en urgencias. Resultados: Se atendió a 3.234 pacientes (3,48% del total de urgencias médicas), con una media de 11,15 pacientes/día. La edad media fue de 59 años. Las enfermedades más frecuentes fueron la cerebrovascular (34%), epilepsia (16%) y cefalea (8%). La estancia media en urgencias fue de 7,17 h. La tasa de ingreso hospitalario fue del 40% (7,38% del total de ingresos urgentes por afección médica). Los principales destinos de los pacientes hospitalizados fueron Unidad de Ictus (39,5%) y la planta de Neurología (33%). Se realizaron 76 procedimientos trombolíticos o intravasculares en ictus agudos. El 70% de los pacientes fue valorado fuera del horario laboral. Conclusiones: La atención neurológica es frecuente, variada y compleja, representando un alto porcentaje sobre el total de paciente atendidos o ingresados en urgencias. Nuestros resultados justifican la presencia física de un neurólogo de guardia 24 h en urgencias

Introduction: Population ageing, the rising demand for healthcare, and the establishment of acute stroke treatment programs have given rise to increases in the number and complexity of neurological emergency cases. Nevertheless, many centres in Spain still lack on-call emergency neurologists. Methods: We conducted a retrospective study to describe the role of on-call neurologists at Hospital General Universitario Gregorio Marañon, a tertiary care centre in Madrid, Spain. Sociodemographic characteristics, most common pathologies, diagnostic tests, and destination of the patients attended were recorded daily using a computer database. Results were compared with the general care data from the emergency department. Results: The team attended 3234 patients (3.48% of the emergency department total). The mean number of patients seen per day was 11.15. The most frequent pathologies were stroke (34%), epilepsy (16%) and headache (8%). The mean stay in the emergency department was 7.17 hours. Hospital admission rate was 40% (7.38% of emergency hospital admissions). The main destinations for admitted patients were the stroke unit (39.5%) and the neurology department (33%). Endovascular or thrombolytic therapies were performed on 76 occasions. Doctors attended 70% of the patients during on-call hours. Conclusions: Emergency neurological care is varied, complex, and frequently necessary. Neurological cases account for a sizeable percentage of both patient visits to the emergency room and the total number of emergency admissions. The current data confirm that on-call neurologists available on a 24-hour basis are needed in emergency departments

Aproximación antropológica al síndrome de dolor miofascial. Una propuesta de intervención / No disponible

Objetivos: - Estudiar el síndrome de dolor miofascial (SDM) desde una perspectiva distinta a la clínica. - Abordar mediante un enfoque interdisciplinar el SDM crónico. - Elaborar una propuesta de intervención sobre el paciente con SDM crónico considerando aspectos antropológicos del dolor. Métodos: Se ha dividido el trabajo en dos partes; una primera en la que se ha realizado una búsqueda de literatura científica relacionada con el objeto de estudio y una segunda en la que, a partir de los resultados obtenidos, se han elaborado las conclusiones a modo de propuesta de intervención. Resultados: Los aspectos antropológicos del SDM no han sido un objeto de estudio habitual por lo que ha sido necesario recurrir a los trabajos sobre el dolor en general: - El dolor va más allá de la experiencia personal y subjetiva del que lo padece, la expresión del mismo y la validación por parte del entorno social responde a factores socioculturales. - El dolor agudo y el dolor crónico tienen unas connotaciones socio-culturales distintas, la literatura científica señala la importancia de encontrar la causalidad para una vivencia más positiva del dolor. - La actitud del terapeuta y la información al paciente son elementos claves en el proceso recuperador. Conclusiones: - Entender el dolor no solo como un hecho natural y subjetivo sino también como una conducta socialmente aprehendida y culturalmente transmitida, influenciada por muchos factores externos. - Necesidad de integrar empatía y "extrañamiento" en el abordaje del paciente con SDM. - Informar al paciente de manera clara y concisa acerca de su proceso de recuperación para convertirle en parte activa del tratamiento. - Necesidad de diseñar líneas de investigación que imbriquen al estudio del SDM con las ciencias sociales en aras a una mayor interdisciplinariedad que redunde en una concepción holística del paciente (AU)

Objectives: - Study the myofascial pain syndrome (MPS) from a different perspective to the clinical one. - Approach chronic MPS by means of an interdisciplinary point of view. - Develop a proposal for intervention in patients with chronic MPS considering anthropological aspects of pain. Methods: Work has been divided into two parts: the first one in which you conduct a search of scientific literature related to the object of study and a second one in which, from the results obtained, conclusions are drawn up to propose intervention. Results: Anthropological aspects of MPS have not been a regular subject of study. Therefore it has been necessary to use studies on pain in general: - Pain goes beyond the personal and subjective experience of those who suffer, the expression, and validation by social environment respond to socio-cultural factors - Acute and chronic pain have a different socio-cultural connotations, scientific literature indicates the importance of finding causality for a more positive experience of pain. - The attitude of the therapist and patient information are key elements in the process of recovery. Conclusions: - Understand the pain not only as a natural and subjective fact but also as a socially learned and culturally transmitted behaviour, influenced by many external factors. - Need to integrate empathy and "estrangement" in addressing the patient with MPS. - Inform the patient clearly and concisely about his recovery process to become an active part of treatment. - Need to develop lines of research so that the study of MPS interacts with social sciences in order to obtain a greater interdisciplinarity which results in a holistic conception of the patient (AU)

[A robotic system for gait re-education in patients with an incomplete spinal cord injury]. / Sistema robotizado para la reeducación de la marcha en pacientes con lesión medular incompleta.

INTRODUCTION: A spinal cord injury involves the loss or alteration of motor patterns in walking, the recovery of which depends partly on the rearrangement of the preserved neural circuits. AIM. To evaluate the changes that take place in the gait of patients with incomplete spinal cord injuries who were treated with a robotic walking system in association with conventional therapy. PATIENTS AND METHODS: The study conducted was an open-label, prospective, descriptive trial with statistical inference in patients with C2-L3 spinal cord injuries that were classified as degrees C and D according to the American Spinal Injury Association (ASIA) scale. The variables that were analysed on the first and the last day of the study were: number of walkers, 10-m gait test, the Walking Index for Spinal Cord Injury scale revision, technical aids, muscle balance in the lower limbs, locomotor subscale of the measure of functional independence, modified Ashworth scale for spasticity and the visual analogue scale for pain. At the end, data were recorded from the impression of change scale. The analysis was conducted by means of Student's t, chi squared and Pearson's correlation; p < or = 0.05. RESULTS: Forty-five patients, with a mean age of 44 +/- 14.3 years, finished the study; 76% were males, injury was caused by trauma in 58% of cases, and the time of progression was 139 +/- 70 days. Statistically significant increases were observed in the number of subjects capable of walking, walking speed, less need for technical aids, strength in the lower limbs and independence in activities of daily living. CONCLUSIONS: Treatment using the robotic system in association with conventional therapy improves walking capacity in patients with incomplete spinal cord injuries.

Coreoatetosis tras encefalitis herpética / Choreoathetosis after Herpes Simplex encephalitis

Tras una encefalitis herpética (EH), una cuarta parte de los pacientes con EH tiene una recaída de la enfermedad que, excepcionalmente, se manifiesta como un síndrome extrapiramidal de tipo coreoatetósico. La base fisiopatológica de este tipo de recaída es desconocida, pero se hipotetiza que puede ser un cuadro inmunitario mediado. Se presenta el caso de un niño de 8 meses con EH por virus del herpes simple tipo 1 que en la tercera semana de evolución tuvo una recaída caracterizada por un síndrome extrapiramidal con coreoatetosis y balismo. El cuadro se interpretó como postinfeccioso, inmunitario mediado. Se trató al paciente con corticoides en altas dosis e inmunoglobulinas, además de un nuevo ciclo de aciclovir. La coreoatetosis fue tan grave y resistente a los fármacos que obligó a sedorrelajar al paciente inicialmente. Posteriormente, se ensayó tratamiento con tetrabenazina. Se estudió a escala molecular una mutación en el receptor tipo Toll 3, que se ha relacionado con la susceptibilidad de presentar la enfermedad, que resultó ser negativa (AU)

After Herpes simplex encephalitis, 25% of cases may have a relapse, rarely as a choreoathetosic movement disorder. The anatomic basis for herpes simplex virus encephalitis-associated movement disorders remains poorly understood, but the hypothesis is that it may be due to a post-infectious immune-mediated process. We report an 8-month-old boy, with herpes simplex encephalitis type 1, who started with an extrapyramidal Syndrome, presenting with choreoathetosis and ballistic movements, three weeks after onset. These new symptoms were attributed to a post-infectious immune-mediated process. We treated our patient with corticosteroids at high dose and gamma-globulins, in addition to a new course of Acyclovir. Sedation was required to control the intense choreoathetosic movements. Tetrabenazine was also tried, unsuccessfully. We studied a mutation on the toll like receptors (TLR3), which has been related to susceptibility for the disease, which was negative (AU)

[Temporal lobe epilepsy. Aetiological classification in 61 paediatric patients]. / Epilepsia del lóbulo temporal. Clasificación etiológica en 61 pacientes en edad pediátrica.

INTRODUCTION: There are very few studies on the aetiology of temporal lobe epilepsy (TLE) in childhood. The purpose of the present study is to analyse the data of 61 children diagnosed with TLE, in order to describe the aetiology of TLE in children seen in a neuropaedriatic clinic. We also discuss the currently proposed classification. PATIENTS AND METHODS: A retrospective analysis was carried out on patients diagnosed with TLE. Patients consisted of 61 children less than 15 years old. RESULTS: Patients were classified into three groups: Group 1 (symptomatic temporal lobe epilepsy) consisted of 25 patients (40.98 %) with any temporal lesion on neuroimaging (tumours, malformations or infections) or significant history; Group 2 (Mesial temporal sclerosis) consisted of 17 patients (27.86 %), a history of simple and complex febrile seizure were common in this group; and Group 3 (Cryptogenic epilepsy) consisted of 19 patients (31.15 %) with no abnormalities on neuroimaging or significant history. CONCLUSION: To our knowledge, this is the largest paediatric series of childhood new-onset TLE assessed only by MRI in the literature. We have modified the previous aetiological classification in order to make the groups more realistic.

Epilepsia del lóbulo temporal. Clasificación etiológica en 61 pacientes en edad pediátrica / Temporal lobe epilepsy. Aetiological classification in 61 paediatric patients

Introducción. La etiología de la epilepsia del lóbulo temporal (ELT) en la edad pediátrica se ha descrito en escasas ocasiones. El propósito de este estudio es analizar el diagnóstico etiológico de 61 pacientes con ELT atendidos en una consulta de neurología infantil. Analizamos y comentamos la clasificación actual. Pacientes y métodos. Se trata de un estudio de carácter retrospectivo, en el que se incluyó a 61 pacientes con ELT. Resultados. Los pacientes fueron clasificados en tres grupos en función del diagnóstico etiológico: grupo 1 (ELT sintomática), incluye a 25 pacientes (40,98 %) con lesiones en el lóbulo temporal (malformación, tumor o infección) o antecedentes significativos para presentar epilepsia; grupo 2 (esclerosis mesial temporal [EMT]), incluye a 17 pacientes (27,86 %), el antecedente de crisis febriles (tanto simples como complejas) se encontraba presente en un porcentaje elevado de pacientes con EMT; grupo 3 (ELT criptogénica), incluye a 19 pacientes (31,15 %), sin hallazgos patológicos en la resonancia magnética (RM) craneal o antecedentes significativos. Conclusión. Hasta la fecha, es la mayor serie que analiza, mediante RM, la etiología de la ELT de comienzo en la edad pediátrica. Hemos pretendido matizar la clasificación etiológica más aceptada, con el propósito de hacer grupos más flexibles y realistas

Introduction. There are very few studies on the aetiology of temporal lobe epilepsy (TLE) in childhood. The purpose of the present study is to analyse the data of 61 children diagnosed with TLE, in order to describe the aetiology of TLE in children seen in a neuropaedriatic clinic. We also discuss the currently proposed classification. Patients and methods. A retrospective analysis was carried out on patients diagnosed with TLE. Patients consisted of 61 children less than 15 years old. Results. Patients were classified into three groups: Group 1 (symptomatic temporal lobe epilepsy) consisted of 25 patients (40.98 %) with any temporal lesion on neuroimaging (tumours, malformations or infections) or significant history; Group 2 (Mesial temporal sclerosis) consisted of 17 patients (27.86 %), a history of simple and complex febrile seizure were common in this group; and Group 3 (Cryptogenic epilepsy) consisted of 19 patients (31.15 %) with no abnormalities on neuroimaging or significant history. Conclusion. To our knowledge, this is the largest paediatric series of childhood new-onset TLE assessed only by MRI in the literature. We have modified the previous aetiological classification in order to make the groups more realistic

[Intracranial venous thrombosis: reports on 11 paediatric cases]. / Trombosis venosa intracraneal:a propósito de 11 casos pediátricos.

INTRODUCTION: Intracranial venous thrombosis (IVT) is a rare condition at the paediatric age, with a wide variety of clinical features and causations. AIM: To describe the etiopathogenic factors, the presenting symptoms, diagnosis, treatment and progress of the cases of IVT diagnosed at the Hospital 12 de Octubre. PATIENTS AND METHODS: The descriptive retrospective study involved reviewing the records of patients who were admitted to hospital between 1989 and 2005, with ages ranging between 1 month and 16 years. Those who had been diagnosed as having IVT, confirmed by neuroimaging, were selected for the study. A review of their patient records was then carried out and associated etiopathogenic factors, clinical features and neuroimaging findings, treatment and progress were analysed. RESULTS: Eleven patients fulfilled clinical and radiological eligibility criteria. Most of them presented precipitating factors of an infectious origin (45%). The most frequent presenting symptoms were headache and diminished level of consciousness (45% for each case). The superior longitudinal was the most commonly affected venous sinus (72% of cases). Thrombophilic alterations were found in 27% of the patients. Magnetic resonance imaging of the brain was the most cost-effective diagnostic test. No haemorrhagic complications were recorded in patients receiving anti-clotting therapy. In most cases progress was favourable. CONCLUSIONS: Improved diagnostic methods allow IVT to be detected increasingly more often at the paediatric age. Anti-clotting therapy in the acute phase proved to be safe and effective in this series, although further studies are needed with patients at this age to confirm this finding.

Trombosis venosa intracraneal: a propósito de 11 casos pediátricos / Trombosis venosa intracraneal: a propósito de 11 casos pediátricos

La trombosis venosa intracraneal (TVI) constituye una patología rara en la edad pediátrica, congran variabilidad clínica y etiológica. Objetivo. Describir los factores etiopatogénicos, la presentación clínica, el diagnóstico, el tratamiento y la evolución de los casos diagnosticados de TVI en el Hospital 12 de Octubre. Pacientes y métodos. Estudiodescriptivo retrospectivo en el que se revisaron los informes de pacientes ingresados entre los años 1989 y 2005, con edades comprendidas entre 1 mes y 16 años. Se seleccionaron aquéllos diagnosticados de TVI confirmada con neuroimagen. Se procedió a una revisión de su historia clínica, analizando factores etiopatogénicos asociados, clínica y hallazgos en neuroimagen,tratamiento y evolución. Resultados. Once pacientes reunieron los criterios clínicos y radiológicos de inclusión. Lamayoría presentó factores desencadenantes de etiología infecciosa (45%). Los síntomas de presentación más frecuentes fueronla cefalea y la disminución del nivel de conciencia (un 45% cada una). El seno venoso más frecuentemente afectado fue el longitudinal superior en un 72% de los casos. Se hallaron alteraciones trombofílicas en el 27% de los pacientes. La resonanciamagnética cerebral fue la prueba de mayor rentabilidad diagnóstica. No se registraron complicaciones hemorrágicas en los pacientes anticoagulados. La evolución mayoritaria fue favorable. Conclusión. Se reconoce cada vez más la TVI en la edad pediátrica gracias a las mejoras en los métodos diagnósticos. La anticoagulación en la fase aguda ha resultado segura y eficaz en esta serie, aunque se precisan más estudios en esta edad para confirmarlo

[Doubts and confusions in the diagnosis and treatment of positional plagiocephaly. Management protocol]. / Enigmas y confusiones en el diagnóstico y tratamiento de la plagiocefalia posicional. Protocolo asistencial.

INTRODUCTION: Positional plagiocephaly is currently the most frequent cause of consultation at pediatric neurosurgical departments in Spain and other western countries. There is considerable confusion in the literature on the terminology and physiopathology of this deformity, as well as its differential diagnosis with true synostosis and treatment recommendations. OBJECTIVES: To clarify these concepts and present a protocol for the management of positional plagiocephaly, which was recently requested by the Health Administration of the Community of Madrid. PROTOCOL: The protocol aims to achieve coordination among pediatricians and neurosurgeons, as well as to provide precise information on this deformity for parents, pediatricians and neurosurgeons. MATERIAL AND METHODS: Previous consensus was reached on a series of data. Infants were classified into three categories of deformity (mild, moderate, severe) according to measurements on digital photographs. Diagnosis and treatment follows two phases: a pediatric phase (up to 5 months of age) and a neurosurgical phase (from 5 months onwards). Infants are referred to neurosurgical consultation only after being treated with postural changes and physiotherapy and only after reaching the age of 5 months. The reasons for this approach are explained in the protocol, which also defines the functions and responsibilities of each specialty. CONCLUSION: The treatment proposed in the protocol is staged, starting with postural changes and physiotherapy, followed by orthotic cranial devices and finally surgical treatment.

Enigmas y confusiones en el diagnóstico y tratamiento de la plagiocefalia posicional. Protocolo asistencial / Doubts and confusions in the diagnosis and treatment of positional plagiocephaly. Management protocol

Introducción La plagiocefalia posicional es actualmente la causa más frecuente de asistencia en una consulta de neurocirugía pediátrica, tanto en España como en todos los países occidentales. A ello se suma la considerable confusión existente en la literatura especializada en relación a aspectos como la terminología, conceptos fisiopatológicos, diagnóstico diferencial con la craneosinostosis y por supuesto en el tratamiento más adecuado que hay que seguir. Objetivos Intentar clarificar estos conceptos y además presentar un protocolo de asistencia que nos ha solicitado recientemente la Administración Sanitaria de la Comunidad de Madrid. Protocolo Pretende lograr la coordinación entre pediatras y neurocirujanos, así como conseguir una información precisa de los principales datos de esta patología para los familiares, pediatras y neurocirujanos. Material y métodos Se establecen una serie de datos de consenso. Los niños son clasificados en 3 grados de deformación (leve, moderada y grave) según los índices medidos en fotografías digitales. Además el proceso del diagnóstico y tratamiento tiene dos fases: fase pediátrica (hasta los 5 meses de edad) y fase neuroquirúrgica (desde los 5 meses de edad). Los niños serán enviados a neurocirugía después de haber sido tratados con tratamiento posicional y rehabilitación y solamente a partir de los 5 meses de edad. Las razones de todo ello son explicadas en el protocolo que define también las funciones y responsabilidades de cada especialista. Conclusiones El tratamiento que se propone es escalonado, comenzando por las medidas posicionales y de rehabilitación, seguidas de ortesis craneal y en último lugar del tratamiento quirúrgico
