Jak2 mutation expands the thrombophilic panel in children.

Cerebral sinus venous thrombosis (CSVT) is an important cause of vascular accidents in children. The diagnosis of the underlying disease allows appropriate and timely management of the risk factors and guide therapy, but the etiology remains unknown in 20% to 25% of the cases. We present the first case of a child presenting with CSVT caused by the Janus Kinase 2 (JAK2) V617F mutation, occurring without the hematological abnormalities diagnostic for myeloproliferative neoplasms.

[Encephalitis by type B influenza: a pediatric clinical case and literature review.].

We report the case of a 6-year-old girl who presented with encephalitis during type B influenza. The clinical picture was characterized by an alteration of the state of consciousness associated with focal neurological signs with electroencephalographic changes and brain MRI. Clinical improvement was rapid and without neurological outcomes.

Hand function assessment in the first years of life in unilateral cerebral palsy: Correlation with neuroimaging and cortico-spinal reorganization.

Aim: The purpose of the present study was to correlate early hand function assessment during the first years of life with neuroimaging findings and the different patterns of cortico-motor reorganization in children with unilateral cerebral palsy (UCP).

Methods: We conducted a long prospective observational study, in which 17 children with UCP (8 left-sided hemiplegia; Manual Ability Classification System level 1-3) were first assessed at a mean age of 24 months (range 18-28), and followed up by means of the Besta Scale, a new standardized protocol assessing both unimanual and bimanual hand function. They also underwent Melbourne Assessment of Unilateral Upper Limb Function (MUUL) and single-pulse Transcranial Magnetic Stimulation (TMS) at a mean age of 10 years 5 months (range 9 y 1 m-12 y 8 m).
