          Abstract

          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.

          Resultados.

          Se 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.

          Translated abstract

          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.

          Epidemiology of headache in Europe.

          The present review of epidemiologic studies on migraine and headache in Europe is part of a larger initiative by the European Brain Council to estimate the costs incurred because of brain disorders. Summarizing the data on 1-year prevalence, the proportion of adults in Europe reporting headache was 51%, migraine 14%, and 'chronic headache' (i.e. > or =15 days/month or 'daily') 4%. Generally, migraine, and to a lesser degree headache, are most prevalent during the most productive years of adulthood, from age 20 to 50 years. Several European studies document the negative influence of headache disorders on the quality of life, and health-economic studies indicate that 15% of adults were absent from work during the last year because of headache. Very few studies have been performed in Eastern Europe, and there are also surprisingly little data on tension-type headache from any country. Although the methodology and the quality of the published studies vary considerably, making direct comparisons between different countries difficult, the present review clearly demonstrates that headache disorders are extremely prevalent and have a vast impact on public health. The data collected should be used as arguments to increase resources to headache research and care for headache patients all over the continent.

            Incidental findings in magnetic resonance imaging of the brains of healthy young men.

            To determine the frequency of serious intracranial abnormalities in a healthy young male population. Cranial MRI of 2,536 healthy young males, mean age 20.5 years, all applicants for military flying duties in the German Air Force. The authors report a variety of morphological abnormalities in the brains of a large population of healthy young males, providing data on disease prevalence. Arachnoid cysts were found in 1.7% (95% CI 1.2 to 2.3%), vascular abnormalities in 0.51% (95% CI 0.29 to 0.9%), and intracranial tumors in 0.47% (95% CI 0.26 to 0.85%) of the applicants. No cerebral aneurysms were found. The prevalence of primary brain tumors seems to be higher, whereas the prevalence of intracranial aneurysms is lower than expected. Only a small percentage of the detected abnormalities require urgent medical attention.
