OBJECTIVE Patients with shunts often interact with providers distant from their primary hospital, making it important that the parent(s)/guardian(s) is well versed in the type of shunt implanted and symptoms of malfunction/infection. This is particularly important with magnetic-sensitive programmable valves, as the use of MRI becomes more prevalent. METHODS Over a 6-month period, primary caregivers of 148 consecutive patients who received shunts were prospectively administered questionnaires at clinic visits...

INTRODUCTION: There are very few reports in the literature associating in hydrocephalus in osteopetrosis. As a complication of shunt procedure, there are two reports on shunt malfunction due to osseous overgrowth at the burr hole in patients with osteopetrosis. We herein report a case of osteopetrosis with hydrocephalus that was successfully treated with endoscopic third ventriculostomy (ETV). CASE REPORT: At 5 months of age, a male patient presented with developmental delay...

OBJECTIVE: The role of ventriculomegaly and its interplay between various dementia entities and their pathogenesis, as well as its correlation to the levels of CSF protein markers, remains to be elucidated. Evans index (EI) is a well-established radiological marker in the diagnosis of idiopathic Normal Pressure Hydrocephalus (iNPH), assessing ventricular enlargement. However, there are no previous studies investigating the correlation between EI, age, beta amyloid (Aβ), tau and phosphorylated-tau (p-tau) proteins in the CSF...

BACKGROUND: For intraventricular chemotherapy (IVC) as part of many oncological treatment protocols, Ommaya reservoir is enabling repeated access to the cerebro-spinal fluid (CSF). The correct placement of the catheter in the ventricle is essential for correct application of drugs, which is enabled by sophisticated techniques such as neuronavigation. OBJECTIVE: In a bi-center retrospective study, we reviewed our experience using a smartphone-assisted ventricle catheter guide as simple solution for correct Ommaya reservoir placement...

INTRODUCTION: Recognizing patients with ventriculomegaly who are at risk of developing acute hydrocephalus presents a challenge for the clinician. The association between disturbed cerebrospinal fluid flow (CSF) and impaired brain compliance may play a role in the pathogenesis of hydrocephalus. Phase contrast MRI is a noninvasive technique which can be used to assess CSF parameters. The aim of the work is to evaluate the effectiveness of phase contrast MRI in recognizing patients at risk of acute hydrocephalus, based on measuring the pulsatile CSF flow parameters in the Sylvian aqueduct and prepontine cistern in children with ventriculomegaly...

Pediatric hydrocephalus is characterized by an abnormal accumulation of cerebrospinal fluid (CSF) and is one of the most common congenital brain abnormalities. However, little is known about the molecular and cellular mechanisms regulating CSF flow in the developing brain. Through whole-genome sequencing analysis, we report that a homozygous splice site mutation in coiled-coil domain containing 39 (Ccdc39) is responsible for early postnatal hydrocephalus in the progressive hydrocephalus (prh) mouse mutant. Ccdc39 is selectively expressed in embryonic choroid plexus and ependymal cells on the medial wall of the forebrain ventricle, and the protein is localized to the axoneme of motile cilia...

Fibromyalgia (FM) is a debilitating, widespread pain disorder that is assumed to originate from inappropriate pain processing in the central nervous system. Psychological and behavioral factors are both believed to underlie the pathogenesis and complicate the treatment. This hypothesis, however, has not yet been sufficiently supported by scientific evidence and accumulating evidence supports a peripheral neurological origin of the symptoms. We postulate that FM and several unexplained widespread pain syndromes are caused by chronic postural idiopathic cerebrospinal hypertension...

INTRODUCTION: Myelomeningocele (MMC) is an open neural tube defect routinely surgically closed within 48 h of birth to prevent secondary infection. Up to 18% of patients experience wound complications, and 85% require shunting for hydrocephalus. We hypothesized that wound complications could be reduced by cerebrospinal fluid (CSF) diversion at the time of closure. METHODS: Institutional review board approval was obtained to review records of the 88 patients who underwent MMC closure between January 2005 and June 2016 at the Children's Hospital of Pittsburgh...

The mechanism that maintains a stable blood flow in the brain despite changes in cerebral perfusion pressure (CPP), and therefore guaranties a constant supply of oxygen and nutrients to the neurons, is known as cerebral autoregulation (CA). In a certain range of CPP, blood flow is mediated by a vasomotor adjustment in vascular resistance through dilation of blood vessels. CA is known to be impaired in diseases like traumatic brain injury, Parkinson's disease, stroke, hydrocephalus and others. If CA is impaired, blood flow and pressure changes are coupled and the oxygen supply might be unstable...

Background: Stroke patients requiring decompressive craniectomy are at high risk of prolonged mechanical ventilation and ventilator-associated pneumonia (VAP). Tracheostomy placement may reduce the duration of mechanical ventilation. Predicting which patients will require tracheostomy and the optimal timing of tracheostomy remains a clinical challenge. In this study, the authors compare key outcomes after early versus late tracheostomy and develop a useful pre-operative decision-making tool to predict post-operative tracheostomy dependence...

BACKGROUND: Patients with posterior fossa lesions causing obstructive hydrocephalus present a unique clinical challenge, as relief of hydrocephalus can improve symptoms, but the perceived risk of upward herniation must also be weighed against the risk of worsening or continued hydrocephalus and its consequences. The aim of our study was to evaluate for clinically relevant upward herniation following external ventricular drainage (EVD) in patients with obstructive hydrocephalus due to posterior fossa lesions...
