The purpose of this study was to investigate the value of the change in optic nerve sheath diameter (ONSD) as a radiological marker of endoscopic third ventriculostomy (ETV) outcome in children. ⋯ Change in ONSD is a useful radiological marker of ETV outcome and may be used in combination with conventional radiological parameters to aid decision-making in this difficult group of patients.

Spinal cord infarction is extremely rare in childhood and can result from a wide range of causes. Fibrocartilaginous embolism can give rise to spinal stroke and mimic non-vascular disease such as acute transverse myelitis. ⋯ We outline the key clinical and radiographic features that enable spinal cord infarction to be differentiated from transverse myelitis. Prognosis depends on many factors such as extent and type of injury, level of the cord affected, and age at the time of spinal cord infarction.

Intrathecal baclofen therapy (ITB) has been used in the treatment of spasticity and dystonia. In our pediatric movement disorder clinic, we noted a delay in referral of patients for consideration of ITB. Often, only after years of failed medical therapy, a baclofen pump is considered. This study attempts to investigate the prevalence, length and causes of the delay. ⋯ Despite the limitations of this subjective retrospective analysis of outcomes and delay in referral, the opinions of the parents and caregivers should be considered. Earlier referral for ITB therapy may better treat severe spasticity in pediatric patients.

Reactive gliosis has been implicated in the pathogenesis of communicating hydrocephalus. Because the activation of Wnt/β-catenin signaling pathway is considered as a significant factor to contribute to brain development, neurodegenerative process, and reactive gliosis, we target this pathway for intervention by using sFRP-l and investigated the expression of β-catenin, cyclin D-1, and glial fibrillary acidic protein (GFAP) in the brain of experimental hydrocephalic rats in terms of protein and gene expression. ⋯ These results suggest that regulating Wnt/β-catenin signaling pathway may provide new therapeutic methods for hydrocephalic patients.

Cerebrospinal fluid shunt failure is related to additional morbidity. Misplacement of ventricular catheters occurs in 40 % with freehand technique and is a risk factor for shunt failure. The goal of this study was to analyze the impact of intraoperative real-time ultrasound on catheter positioning and outcome in children. ⋯ This analysis demonstrated an improvement of catheter positioning with ultrasound guidance. In the absence of additional burden or risks, this method should be favored over freehand technique. It remains to be demonstrated in a randomized controlled fashion to what extent improved catheter position translates into improved outcome.
