The objectives of this study were to evaluate the efficacy of percutaneous cardiopulmonary support (CPS) for circulatory assistance during electrophysiological endocavitary procedures for ventricular tachycardia (VT) in high-risk patients. From January to June 1999, eight patients with VT not haemodynamically tolerated, underwent an electrophysiological(More)
OBJECTIVE To evaluate if relative changes in the amplitude of the arterial pulse wave of the cerebral microcirculation (APWCM) measured by near-infrared spectroscopy (NIRS) may provide information about relative changes of cerebral blood flow (CBF) in cerebral cortex. METHODS In 10 healthy human volunteers, through simultaneous recording of the APWCM(More)
Migraine has been associated with an increased risk for ischemic stroke. A recent study suggests that a generalized peripheral vasoconstriction may represent one possible mechanism underlying the increased risk for ischemic stroke. The aim is to verify the presence of cerebral arteriolar vasoconstriction during the interictal period of migraine with (MA+)(More)
The aim of this study is to identify the pathophysiology of migraine attack with prolonged aura (between 1 h and 7 days) not clearly understood. We studied cortical cerebral microcirculation by an innovative near infrared spectroscopy system (NIRS) and cerebral macrocirculation by transcranial Doppler (TCD) in eight subjects (3 M and 5 F, age range 21-41(More)
BACKGROUND AND AIMS A large body of evidence indicates that cerebral hypoperfusion is one of the earliest signs in the development of Alzheimer's disease (AD). The aim of our study was to evaluate whether the brain reperfusion rehabilitation therapy (BRRT) would improve verbal memory and learning and/or global cognitive impairment in mild AD. METHODS(More)
Due to the lack of markers for migraine, diagnosis relies entirely on symptomatology. The aim is to evaluate the utility of a new near-infrared spectroscopy parameter as potential marker for patients with episodic migraine with (MA+) and without aura (MA-) during the interictal period of migraine. We studied 10 patients with MA+ (age 39.5 ± 12.2 years) and(More)
Acoustic noise levels were measured in the Gulf of Catania (Ionian Sea) from July 2012 to May 2013 by a low frequency (<1000Hz) hydrophone, installed on board the NEMO-SN1 multidisciplinary observatory. NEMO-SN1 is a cabled node of EMSO-ERIC, which was deployed at a water depth of 2100m, 25km off Catania. The study area is characterized by the proximity of(More)
The aim was to evaluate whether patients with episodic migraine with (MA+) and without aura (MA-), during the interictal period of migraine would have an altered distensibility of the wall of cerebral arterial network and whether it would play a role in migraine headache. To evaluate the distensibility of the wall of cerebral arterial network, we measured(More)
OBJECTIVE To evaluate the utility of near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD) parameters as potential markers for amnestic mild cognitive impairment (aMCI). METHODS By means of NIRS and TCD, noninvasive and inexpensive technologies, we studied 21 patients with aMCI (10 M and 11 F, 70.2 ± 7.3 years) and 10 age matched healthy(More)
OBJECTIVE To evaluate the utility of a transcranial brain photoplethysmography parameter as a potential marker for patients with multiple sclerosis. METHODS We investigated 38 patients affected by multiple sclerosis, according to the revised McDonald criteria (12 males and 26 females, mean age 41.1 ± 8.5 years, Expanded Disability Status Scale mean value(More)
