Abstract Aim Fluoropyrimidines, including 5‐fluorouracil (5‐FU) and capecitabine, are cornerstone antineoplastic agents for cancer. Case reports suggest that these drugs may be associated with an under‐recognised risk of ischaemic stroke or transient ischaemic attack (TIA).

Mechanisms of Cough Syncope as Evaluated by the Valsalva Maneuver
Transcranial Doppler is often employed for the assessment of cerebral hemodynamics. The study by Chao et al in the February 2007 issue of the journal raises some important issues regarding the understanding of the mechanisms involved in cough syncope. We

Heparin and air filters reduce embolic events caused by intra-arterial cerebral angiography - A prospective, randomized trial [PDF]
Background-Intra-arterial cerebral angiography is associated with a low risk for neurological complications, but clinically silent ischemic events after angiography have been seen in a substantial number of patients.Methods and Results-In a prospective ...

Transcranial Doppler in cerebrovascular disease.
Doppler analysis of flow in intracranial arteries is now possible using a 2 MHz probe allowing sufficient penetration of bone to obtain signals noninvasively.

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Research and Medical Transcranial Doppler System
A new ultrasound digital transcranial Doppler system (digiTDS) is introduced. The digiTDS enables diagnosis of intracranial vessels which are rather difficult to penetrate for standard systems.

Abstract Individuals with persisting post‐concussion symptoms with physiological subtype (PPCS‐P) demonstrate exercise intolerance due to exacerbation of concussion‐like symptoms during incremental exercise. We tested the hypothesis that individuals with PPCS‐P (n = 12) would have a blunted cardiac autonomic response to face cooling compared to healthy

Transcranial Doppler-guided deairing of a pediatric ventricular assist device: experience with twins
We report the intraoperative courses of 2 consecutive Berlin Heart Excor® Pediatric Ventricular Assist Device implantations, in which transcranial Doppler ultrasonography helped to detect macroscopically undetected residual air bubbles captured in the ...

Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...
