Rates of neurocognitive risk range from 35-50% of school-aged children with isolated single suture craniosynostosis (SSC). It has been hypothesized that early surgical intervention to release suture fusion reduces risk for increased intracranial pressure (ICP) and the corresponding risk to neurodevelopment. However, studies assessing children with SSC have been inconsistent in finding an association between neurocognitive development, age of surgery, and ICP. ⋯ Available literature on neurocognitive development of children with SSC is suggestive of mild but persistent neuropsychological deficits, which become more significant as cognitive demands increase at school age. Anatomical studies of children without SSC are beginning to identify particular groups of brain structures that if disrupted or malformed, may be associated with specific cognitive deficits. Controlled research investigating the relationship between persistent anatomical changes and neurocognitive functioning of school-aged children with SSC is needed.

Adjustable vs set-pressure valves decrease the risk of proximal shunt obstruction in the treatment of pediatric hydrocephalus.
The use of programmable shunt valves has increased dramatically in the practice of pediatric hydrocephalus. Despite theoretical advantages, it remains unclear if the use of programmable vs set-pressure valves affects shunt outcome. ⋯ In our experience, the use of programmable vales was associated with a decreased risk of proximal shunt obstruction and shunt revision. Programmable valves may be preferred in patients frequently experiencing proximal shunt failure. A prospective, controlled study is warranted to evaluate the potential value of adjustable vs set-pressure valve systems.

Traumatic epidural hematoma (EDH) represents a rare head injury complication in infants. Its diagnosis can be quite challenging because its clinical presentation is usually subtle and nonspecific. In our current communication, we present our data regarding the presentation of infants with EDH, their management, and their long-term outcome. ⋯ EDH in infants represents a life-threatening complication of head injury, which requires early identification and prompt surgical or conservative management depending on the patient's clinical condition, size of EDH, and presence of midline structure shift on head CT scan. Mortality and long-term morbidity are low with early diagnosis and prompt treatment.

The purpose of this study was to determine the incidence of pseudomeningocele and cerebrospinal fluid (CSF) leak after posterior fossa tumor surgery and to analyze factors that may be associated with these conditions. In particular, we wished to determine if there was evidence to support the hypothesis that the use of tissue glue, dural grafts, or external ventricular drainage (EVD) prevented CSF from leaking outside the closed dura. ⋯ In this retrospective study, the use of tissue glue, dural grafts, and external ventricular drainage was not associated with a reduced rate of clinically or radiologically diagnosed pseudomeningocele formation or postoperative CSF leak. The results of this study provide a basis for planning a randomized controlled trial to determine the effectiveness of tissue glue and/or dural grafting in preventing these complications.

Cerebrospinal fluid (CSF) abdominal pseudocyst is an uncommon but important complication of ventriculoperitoneal shunts. From the collected series, several features about the etiology and management become apparent. Retrospective data were obtained from 12 children treated with cerebrospinal fluid abdominal pseudocyst defined an alternative approach for management of these patients. ⋯ Based on the success rate (75%) in our series submitted to this management, a ventriculoperitoneal shunt can be safely reinserted in the majority of the patients. Endoscopic third ventriculostomy could be performed in selected cases as an alternative approach. Although infection has been reported as responsible for pseudocyst formation, it was only exceptionally found in our series.
