A new method and apparatus for non-disruptive blood pressure (BP) recording in the finger based on the vascular unloading technique is introduced. The instrument, in contrast to intermittent set point readjustments of the conventional vascular unloading technique, delivers BP without interruptions, thus refining the Penáz' principle. The method is based on… (More)

Medical scientists try to improve the accuracy of human body composition measurement by segmental Bioelectrical Impedance Analysis (BIA). Determination of body composition includes estimation of total body water, fat-free mass and extra-and intra-cellular water, which are of great importance in disease states like cancer, malnutrition, disturbances of… (More)
Orthostatic hypotension in patients with cobalamin (Cbl) deficiency has been reported previously in isolated cases but we are not aware of detailed systematic studies of hemodynamic and autonomic nervous system function in patients with cobalamin deficiency. We investigated hemodynamic and autonomic responses to 60 degrees passive head up tilt (HUT) in 21… (More)
20 normotensive subjects (10 with a family history of hypertension) were investigated as to whether moderate salt restriction and/or a high potassium intake had a beneficial effect on blood pressure regulation and prevention of hypertension. In all subjects a moderate reduction of salt intake from 200 to 50 mmol/day over 2 weeks reduced the rise in blood… (More)
Two cases of atypical pineal teratoma (APT) with massive ventricular dissemination are reported; the diagnosis was based on CT appearances and characteristic neurological and endocrinological abnormalities. Both patients responded well to radiotherapy. The CT features and the management of these patients are discussed.
Parallel fluctuations of potential difference (P.D.) across oral and rectal mucosa are probably related to the activity of autonomic nerves rather than adrenal steroids. Unlike rectal mucosa, oral mucosa does not respond to exogenous or endogenous aldosterone. Therefore subtraction of oral P.D. from rectal P.D. gives a closer indication of mineralocorticoid… (More)
