The increased experience in interpretation of fetal echocardiographic images may change the accuracy of fetal echocardiography in diagnosing fetal heart defects. We thus decided to evaluate the specificity and the sensitivity of our fetal echocardiographic examinations in diagnosing congenital heart disease, focusing especially on the outcome of complex cardiac pathologies. Between October 1999...
Certain drugs which affect fetal development are considered. Phenytoin taken during pregnancy may result in infants who remain mentally and physically retarded, with abnormal craniofacial appearance and limb defects. A boy with such a syndrome is reported. Trimethadione is another drug which has been said to be teratogenic, and to cause a typical phenotype which is described. The fetal alcohol ...
Most of our knowledge on the mechanisms of thyroid hormone (TH) dependent brain development is based on clinical observations and animal studies of maternal/fetal hypothyroidism. THs play an essential role in brain development and hormone deficiency during critical phases in fetal life may lead to severe and permanent brain damage. Maternal hypothyroidism is considered the most common cause of ...
OBJECTIVE The aim of this study is to describe the phenotype of fetuses affected by amniotic band sequence (ABS) that were diagnosed at the Instituto Nacional de Perinatología Isidro Espinosa de los Reyes and to propose a new classification based on morphologic findings. MATERIAL AND METHODS Cases with a final diagnosis of amniotic band sequence, diagnosed between January 1993 and July 2010 i...
The fascination with the mystery of new life in utero dates from very early times. For example, Hippocrates made many astute original observations about pregnancy. However, the beginning of real understanding of fetal physiology and development processes is a relatively recent accomplishment. The development of ultrasound and its application to medical diagnosis has been a milestone in fetal me...
In spina bifida the neural tube fails to close during the embryonic period and it is thought that prolonged exposure of the unprotected spinal cord to the amniotic fluid during pregnancy causes additional neural damage. Intra-uterine repair might protect the neural tissue from exposure to amniotic fluid and might reduce additional neural damage. Biodegradable collagen scaffolds may be useful in...
BACKGROUND This study determines the prevalence of Congenital Heart Defects (CHD), diagnosed prenatally or in infancy, and fetal and perinatal mortality associated with CHD in Europe. METHODS AND RESULTS Data were extracted from the European Surveillance of Congenital Anomalies central database for 29 population-based congenital anomaly registries in 16 European countries covering 3.3 million...
