Background: Stroke is the most common neurologic disease and an important cause of morbidity and mortality. Headache is an initial presenting feature of ischemic stroke and sometimes preceedes the development of stroke and thus, provides an opportunity for offering preventive measures. The aim of the present study was to determine the association of new onset headache with stroke. Methods...

losses as well as nitroglycerin and digitalis glycosides were applied with favorable effect to cardiovascular risk patients during the perioperative period.1 3 Frequency of myocardial infarctions and of heart failure during the early postoperative period suggest that in coronary artery disease adrenergic overactivity induces myocardial necrosis and augments the surrounding or preceding "twiligh...

The thermohaline circulation is that part of the ocean circulation which is driven by fluxes of heat and freshwater across the sea surface and subsequent interior mixing of heat and salt. The term thus refers to a driving mechanism. Important features of the thermohaline circulation are deep water formation, spreading of deep waters partly through deep boundary currents, upwelling and near-surf...

Interest in prolonged perfusions has increased pari passu with the possibility of treating the more complicated cardiac deformities. Prolonged perfusions may be of interest also in functional disturbances arising during operations using the heart-lung machine, since it may be difficult to discontinue the perfusion before cardiac function is again satisfactory. Furthermore, the biological change...
