BACKGROUND Length of hospital stay after acute myocardial infarction decreased significantly in the 1980s and 1990s. Whether length of stay has continued to decrease during the 2000s, and the impact of decreasing length of stay on rehospitalization and mortality, is unclear. We describe decade-long (1995-2005) trends in length of stay after acute myocardial infarction, and examine whether decli...

The auricular length, auricular base length and auricular width were measured in 94 human fetuses with crown-rump (CR) lengths ranging from 49 mm (approximately 11 weeks of gestational age) to 250 mm (approximately 31 weeks of gestational age). The three measurement values showed linear increases as the CR length increased, suggesting that they are useful parameters to indicate intrauterine gro...
