Pulmonary hypertension is defined as an abnormal elevation of pressure in pulmonary circulation, with a mean pulmonary arterial pressure higher than 25 mmHg, regardless of the underlying mechanism. The clinical classification system for pulmonary hypertension was updated at the fourth World Symposium on Pulmonary Hypertension in Dana Point, California, in(More)
Anxiety produces maladaptive cardiovascular changes and accelerates biological aging. We evaluated cardiovascular reactivity in young and middle-aged individuals with varying anxiety scores to test the hypothesis that anxiety mimics cardiovascular aging by influencing cardiovascular autonomic modulation. The State-Trait Anxiety Inventory was used to(More)
BACKGROUND The occurrence of hemifacial spasm (HFS) during an episode of migraine has been seldom reported. Here we describe three new cases presenting with HFS in association with migraine attacks. CASE RESULTS Three patients (one woman and two men, aged 31-36 years) developed HFS in close temporal relationship with migraine headaches. All of them(More)
Finger lesions are a frequent problem because of their functional significance and their small size. Because of this, the radiologist has an important role to play in the correct presurgical diagnosis. The aim of this article is to describe the anatomy and the characteristic US and MR findings of the most common tumor and tumor-like lesions of the fingers,(More)
This paper describes an intelligent system for the prediction of forest fire risk in Galicia, a region in northwest Spain. The system has been designed to calculate a risk fire index for each of the 360 squares of 10x10 kms into which the area map has been divided digitally. In our research, the problem was approached using a feedforward neural network. The(More)
Chronic hemodynamic disturbances are more profound in patients with obstructive sleep apnea when underlying lung disease with abnormal gas exchange (low arterial PO2) is present. Previous studies suggest that pulmonary gas exchange could influence the rate of fall of arterial oxygen saturation (dSaO2/dt) in obstructive sleep apnea. We postulated that(More)
