Text comprehension processes were investigated in children with hydrocephalus, a neurodevelopmental disorder associated with good word decoding, but deficient reading comprehension. In Experiment 1, hydrocephalus and control groups were similar in processes related to activating word meanings and using context to enhance meaning. The hydrocephalus group was poorer at suppressing contextually ir...

From 1981 to 1985 a prospective study on normal pressure hydrocephalus was performed. One of the aims of this study was to determine the site of CSF obstruction. Among 17 consecutive patients with a tentative diagnosis of normal pressure hydrocephalus, nine appeared to have non-communicating hydrocephalus most probably due to primary non-tumoural aqueduct stenosis. This unexpected finding provi...

Seventy-five years after Leo Davidhoff made this statement, treatment failure remains the rule, not the exception, in the management of hydrocephalus. Hydrocephalus is the one condition we deal with in neurosurgery where we have made little progress since the development of the shunt valve. We are still using the same basic shunt designs and mechanisms that we have used through all of these yea...

Hydrocephalus is a disorder in which excess cerebrospinal fluid (CSF) collects in the brain. Possible managements for hydrocephalus contain CSF deviation through ventriculoperitoneal shunt assignment and endoscopic third ventriculostomy. An endoscopic third ventriculostomy has been in trend for the past two decades, as a tool in the field of the neurosurgery, for the management of hydrocephalus...

Although hydrocephalus associated with NF-1 is not rare, up to now the MR imaging findings in these patients and the role of ETV in the treatment of hydrocephalus associated with NF-1 have not been investigated thoroughly. We present the MR imaging findings of hydrocephalus associated with NF-1 in 7 of 54 patients with NF-1. Although the types of obstruction were various, including aqueductal w...

Aims To investigate the frequency of ophthalmological abnormalities, the need and timing of eye-care interventions as well as incidence, aetiology and neurological/ neuropsychological outcomes in children with hydrocephalus needing surgical treatment during the first year of life. Patients and Methods Papers I & II: Seventy-five school-aged children (34 girls and 41 boys) with surgically treate...

OBJECT Postresection hydrocephalus is observed in approximately 30% of pediatric patients with posterior fossa tumors. However, which patients will develop postresection hydrocephalus is not known. The Canadian Preoperative Prediction Rule for Hydrocephalus (CPPRH) was developed in an attempt to identify this subset of patients, allowing for the optimization of their care. The authors sought to...

Hydrocephalus formation is a frequent complication of neuropathological insults associated with neuroinflammation. However, the mechanistic role of neuroinflammation in hydrocephalus development is unclear. We have investigated the function of the proinflammatory acting inhibitor of κB kinase (IKK)/nuclear factor κB (NF-κB) signaling system in neuroinflammatory processes and generated a novel m...

BACKGROUND AND PURPOSE Midsagittal morphologic changes often aid in the diagnosis of hydrocephalus. Stretching and upward displacement of the corpus callosum, widening of third ventricular recesses, and decreased mammillopontine distance have been described as indicating the possibility of hydrocephalus. Quantitative studies are scarce. We performed retrospective, quantitative analysis to verif...

BACKGROUND Chronic shunt-dependent hydrocephalus is a complication of aneurysmal subarachnoid hemorrhage (aSAH). Its incidence and risk factors have been described while the hydrocephalus onset in terms of days after treatment (microsurgical or endovascular) has not been yet analyzed. MATERIALS AND METHODS 45 patients, treated for aSAH in 4 Italian Neurosurgical Departments, were retrospectiv...
