Chronically ill patients with neurodegenerative, neurobehavioral and psychiatric diseases commonly have systemic and central nervous system bacterial and viral infections. In addition, other chronic illnesses where neurological manifestations are routinely found, such as fatiguing and autoimmune diseases, Lyme disease and Gulf War illnesses, also show systemic bacterial and viral infections tha...

BACKGROUND AND PURPOSE Endothelin is a potent vasoconstrictor in several tissues, including the choroid plexus. The goal of this study was to determine whether endothelin affects the production of cerebrospinal fluid. METHODS Ventriculocisternal perfusion was used to measure the production of cerebrospinal fluid in anesthetized rabbits. Changes in production of cerebrospinal fluid were examin...

Introduction:Infections are one of the main causes of death during childhood. According to epidemiological studies in Iran, the incidence of neonatal sepsis was 1.8% in year 1995. Moreover, the incidence of neonatal meningitis was 0.2 to 0.4 in 1000 live births. The aim of this study was to determine the necessity of lumbar puncture (LP) for early neonatal sepsis.           Methods:In a retros...

objective(s): the aim of this study wasto investigate the effects of mild hypothermia therapy on oxidative stress injury of rabbit brain tissue after cardiopulmonary resuscitation (cpr). materials and methods: rabbit models of cardiac arrest were established. after the restoration of spontaneous circulation, 50 rabbits were randomly divided into normothermia and hypothermia groups. the followin...

introduction: in some intoxicated patients, cerebrospinal fluid (csf) is examined due to the prolonged loss of consciousness, focal neurologic findings, and fever of unknown origin. we aimed to evaluate the probable relationship between the different toxicity causes and the csf indices in poisoned patients and determine if they could predict the patients’ outcome. methods: all patients who had ...

background: volume estimation of brain is important for many neurological applications. it is necessary in measuring brain growth and changes in brain in normal/abnormal patients. thus, accurate brain volume measurement is very important. magnetic resonance imaging (mri) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. st...

OBJECTIVE To discuss the application of ARMS method to detect EGFR gene mutation in cerebrospinal fluid of lung adenocarcinoma patients with meningeal metastasis. METHODS 5 cases of lung adenocarcinoma were identified with meningeal metastasis that were cleared EGFR gene mutation by gene sequencing method. From each patient 5ml cerebrospinal fluid was obtained by lumbar puncture. ARMS method ...

Background: Infections are one of the most important causes of death in infants, especially in developing countries. Inappropriate use and administration of antibiotics can contribute to the resistance and spread of infection. In this study, we determined the antibiotic resistance pattern of the bacteria isolated from clinical samples of blood, cerebrospinal fluid, and urine in the neonatal int...

We describe a method, correlation force spectrometry (CFS), which characterizes fluids through measurement of the correlations between the thermally stimulated vibrations of two closely spaced micrometer-scale cantilevers in fluid. We discuss a major application: measurement of the rheological properties of fluids at high frequency and high spatial resolution. Use of CFS as a rheometer is valid...

BACKGROUND Cerebrospinal fluid shunt infection can be recalcitrant. Recurrence is common despite appropriate therapy for the pathogens identified by culture. Improved diagnostic and therapeutic approaches are required, and culture-independent molecular approaches to cerebrospinal fluid shunt infections have not been described. OBJECTIVES To identify the bacteria and fungi present in cerebrosp...
