RESUMO

Introducción: Los estudios disponibles ofrecen una guía limitada acerca del uso de la neuroimagen en pacientes con cefalea en el ámbito ambulatorio. El objetivo de este estudio fue describir y analizar la frecuencia y el porcentaje de alteraciones en neuroimagen en pacientes valorados por cefalea en una consulta de neurología, así como determinar qué datos de alarma clínicos (red flags) se asocian con mayor frecuencia a estas alteraciones. Pacientes y métodos: Realizamos un estudio observacional, descriptivo y transversal de una serie de pacientes con cefalea de la consulta de neurología del Hospital Universitario de Móstoles a los que se les realizó una prueba de neuroimagen. ResultadosSe incluyó a 279 pacientes en el estudio (190 mujeres y 89 hombres). Ningún paciente sin datos de alarma clínicos presentó alteraciones graves en la neuroimagen y, de los que presentaban datos de alarma clínicos (219 pacientes), sólo el 2,3% (cinco pacientes) presentó alteraciones graves. Los dos datos de alarma clínicos que se asociaron de forma significativa a una mayor probabilidad de alteraciones graves en la neuroimagen fueron la cefalea que se desencadena o empeora significativamente con cambios posturales o maniobras de Valsalva y la cefalea crónica diaria desde su inicio. Conclusiones: La prevalencia de alteraciones significativas en neuroimagen en pacientes con cefalea en un ámbito ambulatorio fue baja, incluso en presencia de datos de alarma clínicos, por lo que la utilidad de estos datos de alarma parece ser menor en un contexto ambulatorio. Podría ser razonable intentar reducir el uso de la neuroimagen en pacientes con cefalea en el ámbito ambulatorio.(AU)


Introduction: Available studies provide limited guidance on the use of neuroimaging in patients with headache in the outpatient setting. The aim of this study was to describe and analyse the frequency and the percentage of neuroimaging abnormalities in patients evaluated for headache in a neurology clinic, as well as to determine which red flags are most commonly associated with these abnormalities. Patients and methods: We conducted an observational, descriptive and cross-sectional study of a series of patients with headache from the neurology department of the Hospital Universitario de Móstoles who underwent a neuroimaging test. Results: A total of 279 patients (190 women and 89 men) were included in the study. No patient without any red flags had severe abnormalities in the neuroimaging study and, of those with red flags (219 patients), only 2.3% (five patients) displayed severe abnormalities. The two red flags that were significantly associated with an increased likelihood of severe neuroimaging abnormalities were headache that is triggered or significantly worsened by postural changes or Valsalva manoeuvres and chronic daily headache since onset. Conclusions: The prevalence of significant neuroimaging abnormalities in headache patients in an outpatient setting was low, even in the presence of red flags, and so their utility appears to be lower in an outpatient setting. It may be reasonable to try to reduce the use of neuroimaging with headache patients in the outpatient setting.(AU)

RESUMO

OBJECTIVE: To determine the risk, if any, of carbamazepine and valproic acid use on the foetus with respect to neural tube defects. MATERIALS AND METHODS: Databases such as MEDLINE, EMBASE, SCISEARCH, The Cochrane Library and LILACS were consulted to have access to published literature from January 1966 to September 2004. All articles published in English and Spanish were considered. A manual review of the references presented in each produced article was done in order to identify the articles that the electronic search may have not found itself. However, articles which seemed ambiguous as to the title and/or abstract were completely analyzed to establish their relevance. Studies that examined the effects of systematic exposure to carbamazepine or valproic acid during pregnancy and that assessed neural tube defects in the infants were eligible. The data was extracted in the form of 2 x 2 tables. The odds ratio (OR), relative risk (RR) and 95% confidence interval (CI) was calculated for each of the studies. RESULTS: The pooled relative risk of neural tube defects among the exposed to valproic acid was 0.61 (95% CI: 0.06-6.72). The risk among the exposed to carbamazepine was 1.10 (95% CI: 0.16-7-75). CONCLUSIONS: Due to the methodologic limitations of most of the studies where the data was insufficient, only three studies could be included in the meta-analysis. There is not enough evidence to establish the risk raised in the objective of the study.

RESUMO

Objetivo. Establecer el riesgo de desarrollar defectos del tubo neural en los expuestos de forma prenatal a carbamacepina y ácido valproico. Materiales y métodos. MEDLINE, EMBASE, SCISEARCH, The Cochrane Library y LILACS se emplearon para acceder a la literatura publicada entre enero de 1966 y septiembre de 2004. Se tomaron todos los artículos publicados en inglés y español. Se hizo una revisión manual de las referencias presentadas con el fin de identificar artículos que la búsqueda electrónica no identificara. El título y el resumen de los potenciales artículos se analizaron primero antes de solicitar el artículo completo. Sin embargo, artículos que en principio eran ambiguos para determinar su pertinencia también se estudiaron en su totalidad. Se incluyeron los estudios observacionales analíticos que buscaran la presencia de defectos del tubo neural en los hijos de madres expuestas a ácido valproico y carbamacepina durante la correspondiente gestación. Se crearon las tablas de 2 × 2. Los riesgos relativos (RR), las razones de disparidad (OR) y los intervalos de confianza (IC) del 95% se calcularon para cada estudio. Resultados. Se encontró un RR = 0,61 (IC 95%: 0,06-6,72) de desarrollar defectos del tubo neural para quienes están expuestos a ácido valproico en monoterapia. En el caso de exposición a carbamacepina se obtuvo un RR = 1,1 (IC 95%: 0,16-7-75). Conclusiones. Debido a las limitaciones metodológicas de la mayoría de los estudios donde los datos son insuficientes, el metaanálisis sólo pudo incluir tres estudios. No hay evidencia suficiente que permita establecer el riesgo planteado en el objetivo del estudio (AU)
