Isolated fourth ventricles as a consequence of shunted posthemorrhagic hydrocephalus can cause significant brainstem compression and subsequent clinical deficits in children. Several treatment options have been described. We report the clinical and radiological outcome after microsurgical fenestration of fourth ventricular outlet foramen via a suboccipital approach. ⋯ The clinical and radiological outcomes after microsurgical fenestration in children with an isolated fourth ventricle are very promising. This treatment modality is a safe and effective shunt-free option when electrophysiological monitoring and thorough preoperative neuroradiological work-up are applied.

Head injuries constitute one of the leading causes of pediatric morbidity and mortality. Most injuries result from accidents involving an acceleration/deceleration mechanism. However, a special type of head injury occurs when the children sustain a traumatism whose main component is a static load in relation to a crushing mechanism with the head relatively immobile. ⋯ The observed skull, brain, and cranial nerve lesions corresponded to a mechanism of bilateral compression of the children's heads mainly occasioned by a static load, although an associated component of dynamic forces was also involved. The skull and its covering and the cranial nerves were the most severely affected structures while the brain seemed to be relatively well preserved. Most crush injuries appear to be preventable by the appropriate supervision of the children.

Epilepsy and migraine frequently show a clinical overlap. An increase in number of electroencephalographic abnormalities, such as centro-temporal spikes (CTS), may be observed in patients suffering from migraine, epileptic abnormalities that are typically in benign epilepsy of childhood with CTS (BECTS). The aim of this study is to better define the role of CTS in children with migraine compared to children with BECTS, in relation with their neuropsychological profile. ⋯ A similar neuropsychological impairment was found in patients affected by BECTS and in those affected by BECTS and migraine; a significant deficit in short- and long-term verbal memory was evident in patients affected by migraine and CTS. CTS in patients with migraine can influence the neuropsychological tests, with a possible negative impact on language and learning development.

The efficacy and safety of povidone-iodine in wound dressing and irrigation of some operative cavities were established by many in vitro and in vivo experimental reports and clinical series. However, its use in defective tissue in neural structures has not been confirmed yet. The aim of the present study was to histopathologically investigate its effect on neural tissues when applied on the upper side of defective dura. ⋯ Based on the present study, 0.1 % povidone-iodine solution cannot be recommended for wound dressing for neural structures such as myelomeningocele cases because of possible damage to underlying neural tissues.
