  1. 1. Cerebrospinal fluid infusion methods : development and validation on patients with idiopathic normal pressure hydrocephalus

    Författare :Nina Andersson; Anders Eklund; Karin Wårdell; Umeå universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Infusion test; idiopathic normal pressure hydrocephalus; outflow conductance; outflow resistance; intracranial pressure; cerebrospinal fluid dynamics; medical informatics; medicinsk informatik;

    Sammanfattning : Cerebrospinal fluid (CSF) infusion tests can be used to estimate the dynamic properties of the CSF system. Idiopathic normal pressure hydrocephalus (INPH) is a syndrome signified by a disturbance to the CSF system, where the cause is unknown and the diagnosis is difficult to determine. LÄS MER

  2. 2. Cerebrospinal Fluid Shunts in Children : Technical Considerations and Treatment of Certain Complications

    Författare :Kai Arnell; Tomas Wester; Jan Sjölin; Per Enblad; Hans C-son Silander; Uppsala universitet; []
    Nyckelord :Surgery; Hydrocephalus; papilloedema; abdominal cyst; cerebrospinal fluid shunt; shunt infection; intraventricular antibiotic instillation; intraventricular antibiotic concentrations; in-vitro testing; antisiphon device; Kirurgi;

    Sammanfattning : Ventriculo-peritoneal shunting is the most commonly used method for the treatment of paediatric hydrocephalus. Despite improved shunts and surgical techniques there are still complications. This retrospective study focuses on diagnoses and treatment of shunt malfunction and infections. Cost/benefit of using an adjustable shunt was assessed. LÄS MER

  3. 3. Search for Biomarkers in ALS and Parkinson's Disease : Positron Emission Tomography and Cerebrospinal Fluid Studies

    Författare :Anders Johansson; Håkan Askmark; Lennart Persson; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyotrophic lateral sclerosis; ALS; Parkinson’s disease; cerebrospinal fluid; positron emission tomography; vascular endothelial growth factor; fibroblast growth factor 2; proteomics; Fourier transform ion cyclotron resonance mass spectrometry; deprenyl-D2; PIB; FDG; L-[β11C]-DOPA; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : New biomarkers are needed to improve knowledge about pathophysiology, in order to provide earlier correct diagnosis and to follow disease progression of the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD). The aim of this thesis was to find new biomarkers for these diseases. LÄS MER

  4. 4. On cerebrospinal fluid markers of HIV-1 infection

    Författare :Lars-Magnus Andersson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; cerebrospinal fluid; AIDS dementia complex; ganglioside GD3; Tau proteins; neopterin; HIV-1 RNA; blood-brain barrier; albumin ratio; cultivation;

    Sammanfattning : HIV-1 infects the central nervous system early in the course of infection and neurological complications are common in HIV-1-infected individuals. Approximately 20% of individuals with acquired immunodeficiency syndrome (AIDS) not treated with antiretroviral therapy develop a subcortical dementia, AIDS dementia complex (ADC). LÄS MER

  5. 5. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus

    Författare :Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

    Sammanfattning : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. LÄS MER
