Abstract:
A 32-year old man presented with a bilateral faciobrachial paresis, pyramidal signs in the upper limbs and dysarthria. Computer tomographic (CT-)scans showed bilateral cortical zones of contrast enhancement and strikingly symmetrical capsular hypodensities. Angiography revealed a stenosis of the left internal carotid artery and an occlusion of the right internal carotid artery. Essential thrombocythemia was diagnosed as the underlying disorder. Since there are no indications of pontine lesions, we assume that the signs and symptoms in this patient could mainly be attributed to the bilateral capsular lesions, that resemble lacunar infarcts.

Assessment of the Cardiovascular System III: Palpation
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
