The absence of an intra-uterine gestational sac obviously was the most constant sonographic finding among patients with ectopic pregnancy(More)
Abdominal aortic aneurysm (AAA) is present in 5-10% of men aged 65-79 years and is often asymptomatic. The major complication is rupture, which requires emergency surgery. The mortality rate after rupture is high: about 80% of those who reach the hospital and 50% of those undergoing emergency surgery will die. Elective surgical repair of AAA aims to prevent(More)

During the past decade the use of modern intrauterine devices (IUDs) has made(More)
A recent Cochrane systematic review assessed the effects of wearing compression stockings during long-distance flights on the risk of deep-vein thrombosis (DVT). Ten randomised trials were included, 9 of which compared wearing compression stockings on both legs during the whole flight (at least 7 hours) with not wearing compression stockings. In these 9(More)
Tietze and Dixon have studied the average chance of getting pregnant after a single act of unprotected coitus. Tietze concluded that the chance lay between 2% and 4%. Dixon calculated that if the coitus occurred 1 day before ovulation the chance was 17.3%, gradually decreasing to zero toward the 9th day before and 6th day after ovulation. The commonly(More)
The effects of chemotherapy with either Chap-5 (a drug regimen consisting of adriamycin, cis-dichlorodiammine platinum (II), hexamethylmelamine and cyclophosphamide) or Hexa CAF (a drug regimen consisting of methotrexate, 5-fluorouracil, hexamethylmelamine and cyclophosphamide) on the immunocompetence of 22 patients with advanced ovarian carcinoma were(More)
