Las crisis febriles (CFe) son el problema más común en la práctica neurológica pediátrica. Son episodios convulsivos en el curso de una enfermedad febril en ausencia de epilepsia, desequilibrio hidrometabólico severo o neuroinfección. Su diagnóstico es clínico y se clasifican en simples y complejas. El estado epiléptico febril ocurre en aproximadamente el 5% de los casos. Es conveniente enseñar a los padres la forma de actuar ante una crisis y aclarar que una CFe no es una forma de epilepsia, sino un proceso benigno que no suele dejar secuelas neurológicas y en el que la mortalidad es nula. En esta guía clínica se señalan los factores de riesgo de recurrencia, así como las instrucciones de manejo para la primera CFe, los criterios para admisión hospitalaria y el tratamiento para crisis prolongada.

Febrile seizures (FeS) are the most common problem in pediatric neurological practice. They are convulsive episodes during the course of febrile illness in the absence of epilepsy, severe hydroelectrolytic imbalance or neuroinfection. Its diagnosis is clinical and classified as simple and complex. Febrile status epilepticus occurs in approximately 5% of cases. It is convenient to teach parents how to act in a seizure and clarify that a FeS is not epilepsy, it is a benign process that usually does not leave neurological sequelae, and in which mortality is zero. In this clinical guide, we indicate risk factors for recurrence, management instructions for the first FeS, as well as criteria for hospital admission and treatment for prolonged seizures.

Focality in Febrile Seizures: A Retrospective Assessment Using Arterial Spin Labeling MRI

Purpose Defining focality of febrile seizures (FS) in clinical practice remains controversial. We investigated focality issues in FS with a postictal arterial spin labeling (ASL) sequence. Methods We retrospectively reviewed 77 children (median: 19.0 months, range: 15.0–33.0 months) who consecutively visited our emergency room for FS and underwent brain magnetic resonance imaging (MRI), including the ASL sequence, within 24 hours of seizure onset. ASL data were visually analyzed to assess perfusion changes. Factors related to the perfusion changes were investigated. Results The mean time to ASL acquisition was 7.0 (interquartile range: 4.0–11.0) hours. The most common seizure classification was unknown-onset seizures (n = 37, 48%), followed by focal-onset (n = 26, 34%) and generalized-onset seizures (n = 14, 18%). Perfusion changes were observed in 43 (57%) patients: most were hypoperfusion (n = 35, 83%). The temporal regions were the most common location of perfusion changes (n = 26, 60%); the majority of these were distributed in the unilateral hemisphere. Perfusion changes were independently associated with seizure classification (focal-onset seizures, adjusted odds ratio [aOR]: 9.6, p = 0.01; unknown-onset seizures aOR: 10.4, p < 0.01), and prolonged seizures (aOR: 3.1, p = 0.04), but not with other factors (age, sex, time to MRI acquisition, previous FS, repeated FS within 24 hour, family history of FS, structural abnormality on MRI, and developmental delay). The focality scale of seizure semiology positively correlated with perfusion changes (R = 0.334, p < 0.01). Conclusion Focality in FS may be common, and its primary origin might be the temporal regions. ASL can be useful for assessing focality in FS, particularly when seizure onset is unknown.
