On The Dark Side by John Cafferty & the Beaver Brown Band. This was written for Eddie and the Cruisers, a 1983 movie about a New Jersey bar band. In the film, the song becomes the band's big hit and leads to a second album and a conflict with their record company. Kenny Vance was the music supervisor on Eddie and the Cruisers.
The gestational age of 20â29 days was chosen because the fetal size with a crownârump length of 4â6 cm correlates well with the size of a human embryo at about 10â12 weeks, when selective reduction is often performed2.
In the first trimester, gestational sac mean diameter and crown-rump length measurements have become the primary means of evaluating gestational age. 15, 16, 17, 18, 19 In the second and third trimesters, fetal head, body, and extremity measurements have been commonly used to assess gestational age. Physical examination also tends to be inaccurate, especially with advancing gestational age. 10 Bimanual examination in the first trimester may be accurate within Â±2 weeks; however, fundal height measurement, which is more commonly used to assess gestational age, is only accurate within Â±4 to 6 weeks.
