BACKGROUND Volume regulation and hemodynamic functions change during pregnancy, leading to marked increases in blood volume and cardiac output, peripheral vasodilatation and reduced sensitivity to angiotensin. Atrial natriuretic peptide (ANP) is intimately involved in fluid and sodium homeostasis and exerts marked relaxant activity on vascular smooth muscle(More)
133Xe washout measurements were used to determine cutaneous and subcutaneous blood flow beneath a specially designed double-thermostat tc-PO2 electrode. The skin blood flow was determined using thermal methods based on reduced heat dissipation during blood flow cessation. A total of 20 measurements were performed on two healthy volunteers, using the volar(More)
The American Academy of Pediatrics recently released its new Technical Report and Policy Statement on male circumcision, concluding that current evidence indicates that the health benefits of newborn male circumcision outweigh the risks. The technical report is based on the scrutiny of a large number of complex scientific articles. Therefore, while striving(More)
BACKGROUND The reports on plasma concentrations and physiological function of atrial natriuretic peptide (ANP) during pregnancy are conflicting. In a recent prospective study, including 40 healthy primigravidae, we found a highly significant decrease in the plasma concentration of ANP (p-ANP) during the third trimester and the results indicated that ANP(More)
OBJECTIVES The aim of this study was to compare a new sequential estradiol-desogestrel (E2-DSG) hormone replacement regimen (Liseta) with one of the standard treatments i.e. estradiol valerate-medroxyprogesterone acetate (E2V-MPA) combination (Klimalet) regarding the alleviation of climacteric symptoms, vaginal bleeding pattern and the occurrence of adverse(More)
The iliac compression syndrome is caused by impaired venous drainage of the left leg, secondary to compression or stricture of the left iliac vein at, or just before, its junction with inferior vena cava. Serious potential complications are deep vein thrombosis, pulmonary embolism, venous congestion, and the resultant incapacity. Nine patients in whom the(More)
Urinary flow measurement and often retrograde urethrography are used in the postoperative control of urethral strictures treated with urethrotomy. In the present study we have evaluated the usefulness of retrograde urethrography and find that the postoperative control should consist of a history and uroflowmetry.

By use of a combined tc-pO2 skin blood flow sensor E5250 and measurement of cutaneous and subcutaneous blood flows with the 133Xenon washout method it was demonstrated that blood flow in both tissues increases with a factor of 3-4 when the electrode temperature increases from 37 to 45 degrees C. In order to examine the influence of the gas diffusion barrier(More)
A method for estimation of the cutaneous blood flow in transcutaneous PO2 measurements is presented. Recordings of electrode and skin temperature make it possible to compute the effect dissipated to the circulating blood. Eighteen measurements were performed on three healthy volunteers at electrode temperature settings from 37.0 degrees C to 45.0 degrees C.(More)
