Feasibility Study of New MRI Protocol in Assessing Early Blood Brain Barrier Disruption (BBBD)in...

Intra Cerebral Hemorrhage

MRI research Group in the Advanced Technology Center of the Sheba Medical Center has developed an innovative methodology based on leakage (extravasation) contrast agent that allows to map the entire brain with high resolution and high sensitivity to check and describe disorders BBB (blood brain barrier). The aim of the current study is to evaluate the feasibility of the BBB disruption detection method to predict delayed peri - hemorrhage edema.

A Pharmacovigilance Study of Brain Oedema

Brain EdemaBrain Edema Caused by Drugs

Literature reports the development of brain oedema following the use of certain drugs. Therefore, this study aims to present a comprehensive disproportionality analysis of brain oedema cases reported to the Food and Drug Administration Adverse Event Reporting System (FAERS).

The Accuracy of Brain Biological Electrical Impedance Tomography Screen for Supratentorial Tumors...

Brain TumorBrain Edema

Compared with MRI or CT, brain biological electrical impedance tomography were performed on patients with supratentorial tumors and healthy people . The AUC (area under the curve) of ROC, which is associated with the increased maximum and the difference between left and right equilibrium of impedance value, is calculated. The specificity of brain biological electrical impedance tomography in screening supratentorial tumors are evaluated. To compare the changes of parameters detected by brain biological electrical impedance tomography, the enrolled brain tumor patients with cerebral edema were paired with themselves and intravenous infusion of mannitol so that the sensitivity of this device in monitoring cerebral edema can be evaluated.

Correlation of Trans Cranial Doppler Ultrasound and CT Scan in Monitoring of Posttraumatic Brain...

Brain Edema

The most common tool for diagnosis and follow up of cerebral edema in ICU is brain CT scan that necessitate patient transportation with risk of hemodynamic instability, and exposure to radiation. Transcranial Doppler (TCD) sonography allows true and rapid imaging of blood flow velocities of intracranial vessels. Transcranial Doppler sonography provides noninvasive evaluation of intracranial pressure by its characteristic wave patterns

Multi-parameters'Change Process During Dehydration Therapy on Brain Edema Patients.

Hemodynamic InstabilityWater on the Brain1 more

This study aims to investigate the inner mechanism during different dehydration therapies such as mannitol injection and hypertonic saline. The investigators used a self-made near infrared spectroscopy (NIRS) instrument to monitor the physiological changes noninvasively including oxyhemoglobin ([HbO2]), deoxy-hemoglobin ([Hb]), the derived change in blood volume ([tHb]) and water concentration on the forehead of brain edema patients.

Molecular Mechanisms of Malignant Cerebral Edema After LHI

Cerebral Edema

The study is to explore the molecular mechanisms underlying the occurrence of malignant cerebral edema (cerebral hernia) after large hemispheric infarction. Acute LHI (<=48h) patients that develop cerebral hernia or not within 5 days post-stroke onset, as well as the healthy controls will be studied. The participants will be followed for up to 6 months post stroke-onset, and their modified Rankin Scale (mRS) will be recorded. A mRS score of 0-4 is considered as a favorable outcome while a score of 5-6 as an unfavorable one.

Sleep and Cerebral Responses to High Altitude

Acute Mountain SicknessHigh Altitude Pulmonary Edema1 more

Mechanisms underlying high-altitude intolerance as well as exercise performance limitation in hypoxia still remain to be fully understood. Recent data suggest that sleep disturbances on one hand and cerebral perturbations on teh other hand may be key mechanisms. The investigators evaluated 12 healthy subjects at sea level and at 4400 m of altitude for 7 days in order to better describe sleep and cerebral responses. The investigators hypothesized that sleep and cerebral disturbances play a critical role for the developement of acute mountain sickness and for exercise performance limitation during acute high-altitude exposure.
