Hypoplasia of the right ventricle is uncommon as an isolated entity. It may result from tricuspid atresia, but is most commonly secondary to pulmonary atresia with intact ventricular septum.

Sacrococcygeal teratoma ( SCT ) is the most common congenital neoplasm of the fetus. This tumor contains derivatives of more than one of the three embryonic germ cell layers and usually arises as a mass in the sacrococcygeal region.

Trisomy 18 is a serious chromosomal anomaly which has a very poor (usually lethal) prognosis. T18 is usually associated with a variety of sonographically detectable abnormalities.

The embryonic heart rate (EHR) has been found to correlate with gestational age by crown-rump length (CRL) in normal pregnancies. This research compares the EHR and CRL for a population (n=173) in an assisted fertility program, and a population (n=173) of normal pregnancies which were paired by CRLs.

The introduction of the Pill in the 1960’s was probably one of the most liberating events in the history of women. Providing a safe and effective method of contraception, which women could easily control themselves, it enabled women to impact society like never before. Since its introduction, it has probably become one of the most widely studied medications ever.

Contraceptive behavior is related to changing age structure, and change in upper age limits for OCs use. However, there are unpredictable factors affecting contraceptive use such as the publicity regarding OCs and breast cancer and concern about sexually transmitted diseases (STDs) including human immunodeficiency virus infection as well as abortion legislation.

Each year there are millions of unplanned, and often unwanted, pregnancies due to lack of contraception or contraception failure. We have all read about the epidemic of teen pregnancies in the United States and other countries.

The product is an adhesive patch, similar to a large Band Aid®, that a woman places onto her skin to prevent pregnancy. The patch contains hormones that are released through the skin and into the bloodstream.
