Publications reporting experiences with misoprostol alone for pregnancy termination within the first 12 weeks of pregnancy were included in the analysis. Vaginal administration of 800 microg repeated up to three times(More)
OBJECTIVE To compare 400 and 800 microg sublingual or vaginal misoprostol 24 hours after 200 mg mifepristone for noninferiority regarding efficacy in achieving complete abortion for pregnancy termination up to 63 days of gestation.

BACKGROUND Radial access is the preferred route for cardiac catheterization; however, small radial arterial diameters can make complex procedures difficult. The assessment of radial artery diameters prior to intervention may be beneficial for the interventional cardiologist. Our aim was to measure the diameter of radial arteries in a study sample from our(More)
