In 1985, Taiwan started a prenatal DS screening program by means of amniocentesis for pregnant women more than 35 years old. Tests of maternal serum alpha-fetoprotein and human chorionic gonadotropin during the second trimester were begun in 1994.During the past 10 years, the rate of babies with DS born alive has decreased from 76% to 32.2%, and the rate of those stillborn by therapeutic abortion has increased from 23.1% to 73%. Most pregnant women in Taiwan select therapeutic abortion when DS is diagnosed prenatally. The mother of our patient was a 36-year-old woman, gravida 3 previa 3, who gave birth at full term with no known perinatal insult. The woman had received maternal serum screening at 18 weeks gestational age, and the risk was 1:87. The woman was also found to have a thick nuchal fold on prenatal fetal ultrasonography, and refused amniocentesis for religious reasons. The mother was looking forward to the birth and the parents said that the baby was one of nature’s gifts and they respected and were willing to follow the diversity of life. The peripheral blood chromosome count was 47, XX, þ21; a female infant with DS was thus confirmed. (Fig. 1). Our patient is now 3 years 6 months old. The patient’s parents have become active lifelong learners and public educators. They learned the techniques of an early infant stimulation program, and are very familiar with health care systems from different
