1 An appreciation of cultural diversity goes hand-in-hand with a just and equitable society. 2  For example, research has shown that when students' cultures are understood and appreciated by teachers, the students do better in school.
Ectopic pregnancy occurs at a rate of 19.7 cases per 1,000 pregnancies in North America and is a leading cause of maternal mortality in the first trimester. Greater awareness of risk factors and improved technology (biochemical markers and ultrasonography) allow ectopic pregnancy to be identified before the development of life-threatening events.
Ectopic pregnancy is generally diagnosed by serial measurements of the pregnancy hormone called beta hCG and a pelvic vaginal ultrasound. Beta hCG hormone levels double every 2-3 days in the first 6-8 weeks of a normal pregnancy. In 10% of normal pregnancies beta hCG levels may not double every 2-3 days, making the diagnosis of a normal pregnancy difficult. Conversely, in 10% of ectopic pregnancies beta hCG levels may double appropriately, mimicking a normal pregnancy.
