A novel, hands-free ultrasound patch for continuous monitoring of quantitative Doppler in the carotid artery.

Quantitative Doppler ultrasound of the carotid artery has been proposed as an instantaneous surrogate for monitoring rapid changes in left ventricular output. Tracking immediate changes in the arterial Doppler spectrogram has value in acute care settings such as the emergency department, operating room and critical care units. We report a novel, hands-free, continuous-wave Doppler ultrasound patch that adheres to the neck and tracks Doppler blood flow metrics in the common carotid artery using an automated algorithm.

[Oral leukoplakia. A retrospective study of clinical and histological data].

In this retrospective study, the charts of 91 patients who presented with oral leukoplakia at the Department of Oral Surgery and Stomatology at the University of Berne from August 1995 to December 2001 were analyzed. Critical points in the evaluation included the distribution of age and gender of the patients, type and localisation of the oral leukoplakias, grade of dysplasia, presence and type of potential noxious agents, type of surgical/nonsurgical therapy, and follow-up. The 91 patients included in this study had a total of 145 leukoplakias.

The effect of ginkgo biloba extract on free radical production in hypoxic rats.

In the present study, we assayed the antioxidant properties of Ginkgo biloba (Gb) extract on rats submitted to 21 d of chronic hypoxia. Doses of 25 and 50 mg/kg were examined. Oxygenated free radical production measured by the chemiluminescence technique was significantly decreased in treated rats compared to control rats placed in similar experimental conditions, and this effect was more significant at the 50 mg/kg dose.
