Use of greyscale and Doppler ultrasound in initial evaluation and follow-up of neurovascular malformations in children.

Pediatric intracranial arteriovenous shunts are rare vascular malformations that can be diagnosed prenatally or postnatally, as an incidental finding or due to complications. We propose a review of cerebral vascular malformations in newborns and infants with special emphasis on neurosonography and Doppler ultrasound as the first diagnostic method. Sonography can thus contribute in the planning of further studies that are always necessary, and in post-therapy follow-up.

Exantema Mucocutáneo inducido por Mycoplasma Pneumoniae / Mucocutaneous exanthema induced by Mycoplasma pneumoniae

La infección por Mycoplasma pneumoniae (MP) puede presentar un exantema mucocutáneo grave. Esta entidad, denominada Exantema mucocutáneo inducido por Mycoplasma pneumoniae (EMIM), se caracteriza por presentar una epidemiología, fisiopatología, manifestaciones clínicas, y evolución que la diferencian del síndrome de Stevens Johnson, de la necrólisis epidérmica tóxica, y del exantema multiforme. Se presenta el caso de un niño de 5 años de edad con mucositis oral y genital graves asociadas a infección respiratoria aguda baja con rescate de MP en aspirado nasofaríngeo. Se diagnostica EMIM. Los autores del presente artículo realizan una revisión de la bilbiografía y exponen conceptos y definiciones actualizados que permiten catalogar este cuadro como una entidad independiente

Mycoplasma pneumoniae (MP) infection can present with a severe mucocutaneous exanthema. This entity, called mucocutaneous exanthema induced by Mycoplasma pneumoniae (EMIM), is characterized by an epidemiology, pathophysiology, clinical manifestations, and evolution that differentiate it from Stevens Johnson syndrome, toxic epidermal necrolysis, and exanthema multiforme. We present the case of a 5-year-old boy with severe oral and genital mucositis associated with low acute respiratory infection with MP rescue in nasopharyngeal aspirate. EMIM is diagnosed. The authors of this article conduct a review of the bibliography and present concepts and updated definitions that allow cataloging this disease as an independent entity
