Adverse environmental exposures in pregnancy: teratology in adolescent medicine practice
1Greenwood Genetic Center, South Carolina 29646, USA.
Insights
Teratogens, agents causing birth defects, account for 10% of human disabilities. Educating physicians on teratology principles is crucial for preventing fetal defects from maternal exposures.
Area of Science:
- Teratology
- Developmental Toxicology
- Reproductive Health
Background:
- Teratogens are agents causing structural or functional disabilities in embryos or fetuses.
- Approximately 10% of all human birth defects are attributed to teratogens.
- Understanding teratogenic effects is vital for prenatal health.
Purpose of the Study:
- To emphasize the importance of physician education in teratology.
- To highlight the preventable nature of many fetal defects caused by teratogens.
- To underscore the need for recognizing anomalies associated with maternal exposures.
Main Methods:
- Review of teratology principles.
- Analysis of the spectrum of human teratogens.
- Discussion on recognition of associated anomalies.
Main Results:
- Teratogens encompass diverse agents including drugs, chemicals, infections, and maternal conditions.
- A significant percentage of birth defects stem from teratogenic exposures.
- Many adverse fetal outcomes are preventable through informed maternal care.
Conclusions:
- Comprehensive education for healthcare providers on teratology is essential.
- Early recognition and management of teratogenic exposures can prevent birth defects.
- Preventing teratogen exposure is key to reducing the incidence of congenital anomalies.
Abstract:
A teratogen is any drug, chemical, infectious or physical agent, or maternal disease or altered metabolic state that causes a structural or functional disability by acting on the embryo or fetus. Teratogens are responsible for approximately 10% of all human birth defects. Education of physicians caring for children and adolescents in the basic principles of teratology, the spectrum of human teratogens, and the recognition of associated anomalies is essential, because many maternal exposures and resultant fetal defects are completely preventable.
