Active clinical trials for "Hydrocephalus"

Title of clinical study:Clinical application, validation, and functionality evaluation of the Mobile Head Circumference Application in neonates and children Sponsor: University Hospitals NHS Foundation Trust Purpose of study:Evaluate and validate the utility of the mobile Head Circumference application for use in the clinical and outpatient setting for evaluation of head circumference of neonates and infants Primary objectives:Evaluate usefulness of and feasibility of the application in the clinical setting comparing it to normal practice. Secondary objectives:Evaluate parent/guardian reliability and satisfaction of the use of the mobile head circumference app. Study Design:Prospective Sample Size:Treating clinicians employed by Cambridge University Hospitals NHS Foundation Trust will identify patients eligible for this study (infants <18 months of age) and notify research team members with the patient's/guardian's consent. Once identified, research team members will approach patients' parents/guardians to seek informed consent before their clinic appointment or at the bedside on the ward. An information sheet will be used. If they choose to participate, we will measure the HC during the clinic appointment or on the ward. (Please refer to Flowchart 1). Sample size estimation was calculated with 90% statistical power to detect a change of means by 1 and a standard deviation of 1. This, along with 10% iteration, equals 33 participants. Summary of eligibility criteria:Neonatal patients and infants with need of continuous measurement of Head Circumference up to the age of 18months. Investigational techniques:Mobile application for Automatic measurement of head circumference.

PROLIPHYC is a collaborative prospective study that aims at discovering deep cerebrospinal fluid (CSF) proteome with a new clinically-compatible proteomics strategy, in a cohort of 100 patients suspected of neurodegenerative diseases and/or normal pressure hydrocephalus.

In normal patients, blood and cerebrospinal fluid (CSF) contain circulating cells and other molecules such as proteins and nucleic acids. In patients with central nervous system (CNS) and other conditions, the levels of these molecules may be altered. In several other studies at our institution, the investigators are investigating such molecules in tumor specimens as well as the blood and cerebrospinal fluid of pediatric patients with CNS tumors. However, these levels are difficult to interpret without comparing them to levels in patients without CNS tumors. The investigators propose a study to collect small amounts of blood and cerebrospinal fluid from pediatric patients without CNS tumors who are undergoing a diagnostic or therapeutic neurosurgical procedure aimed at addressing altered CSF dynamics.

The purpose of the study is to determine the predictive values and prognostic accuracies of CSF dynamic measures, the TAP -TEST (high-volume cerebrospinal fluid withdrawal), resistance to CSF outflow and compliance in the prediction of shunt-treatment outcome in patients with idiopathic normal pressure hydrocephalus.

Shunt failure remains a significant problem in pediatric patients with hydrocephalus. If reliable techniques for the accurate placement of ventricular catheters can be developed, shunt survival may improve. The purpose of this study is to assess the efficacy and safety of the ultrasound guided shunt insertion technique in the hands of experienced surgeons. The primary outcome measure is ventricular catheter location determined from post-operative brain images. The study is being conducted by the Hydrocephalus Clinical Research Network (HCRN), a network established to conduct multi-institutional clinical trials on pediatric hydrocephalus. Pediatric neurosurgeons at HCRN centers enrolled in this study will perform either ultrasound guided shunt surgery or a conventional shunt surgery. Patients who undergo conventional shunt surgery will serve as a contemporary control group.

It is known that 33-50% of Classic and Hypermobile Ehlers-Danlos Syndrome patients eventually develop dysautonomia, otherwise known as "POTS" (Postural Orthostatic Tachycardia Syndrome). Some of these patients develop dysautonomia as a result of a retroflexed odontoid, Chiari 1 Malformation or cranial settling and the resulting basilar impression. Many Ehlers-Danlos patients suffer with the same symptomology with no evidence of a cause according to MRI imaging. It is the author's hypothesis that low-level External Communicating Hydrocephalus appears to be responsible for the constellation of autonomic and cranial nerve symptoms, and if present in the very young, an analysis of head circumference growth in the first 15 months of life should reflect abnormally rapid head growth, supporting this hypothesis.

This multicenter, prospective pilot study will compare the effectiveness of two established procedures used in the treatment of post-hemorrhagic hydrocephalus in very low birth weight infants, specifically ventricular reservoirs and subgaleal shunts. The study is being conducted by the Hydrocephalus Clinical Research Network (HCRN), a network established to conduct multi-institutional clinical trials on pediatric hydrocephalus.

The overall aim of the registry is to develop a longitudinal, observational database that is focused on adult patients with Normal Pressure Hydrocephalus (NPH) that can be used as a source of clinical information for individual surgeons, as well as a national data repository for scientific inquiry and publications.

Lower urinary tract dysfunction in normal pressure hydrocephalus has received little attention from the scientific community. Urinary symptoms in normal pressure hydrocephalus are mainly represented by overactive bladder, which is a significant burden for the concerned patients. A harmonization of neuro-urological practices in the pre-therapeutic evaluation of patients suffering from normal pressure hydrocephalus is necessary. The investigators conducted a bicentric prospective study aiming to evaluate the effect of depletive lumbar puncture on urinary symptoms in iNPH. The secondary objective was to evaluate, in the same participants previously diagnosed, the effect of cerebrospinal fluid shunt surgery on urinary symptoms.

HS-1000 device, a proprietary new non-invasive brain monitor, is expected to safely and accurately monitor physiological signs of the brain with minimal discomfort to patients, providing information about normal or abnormal brain-related conditions and providing decision-making support for physicians. Investigators hypothesis that the HS-1000 is capable of detecting and monitoring various neuropathologies, using the acoustic raw data derived from the noninvasive procedure.
