"BIRTH DEFECT" The idea in "birth defects" has evolved beyond the original emphasis on structural congenital malformations. Birth Defects are defined broadly by The March of Dimes Birth Defects Foundation, The World Alliance of Non-Governmental Organizations for the Prevention of Birth Defects and by most U.S. governmental and academic organizations. The current "operating" definition is: "ANY STRUCTURAL OR FUNCTIONAL ANOMALY MANIFESTING AT ANY AGE OF ENVIRONMENTAL OR GENETIC NATURE (inherited or not) DUE TO CAUSES ACTING BEFORE BIRTH" Such definition includes sug> MEAN MEANING mental retardation and sug> OLIGOPHRENIA other functional disorders such as sug> DYSFUNCTION chemical metabolic disorders as well as sug> DYSPLASIA many forms of childhood cancer sug> ONCOLOGY connective tissue sug> DYSGENESIS degenerative disorders sug> DYSPLASIA deformations if due to prenatal causes sug> DYSMORPHOLOGY History: The March of Dimes Birth Defects Foundation evolved from the The Poliomyelitis Foundation (Infantile Paralysis), organized by President F D ROOSEVELT [#] and his partner Basil O'CONNOR [#]. After the Foundation reached its goal - the development of Poliomyelitis vaccines - the organization shifted its attention toward arthritis. It was then that Dr. Josef Warkany called attention that congenital malformations could be caused by environmental (ecology) factors now called teratogens. For centuries it was believed that the womb (uterus or maternal matrix) safeguarded the unborn from environmental damage. Scientific facts shattered this dogma. No longer could birth "defects" be seen as solely due to "parental" "genetic" flaws, an idea exploited by enthusiasts advocating state imposed "eugenic" policies. The work of Josef Warkany and others gave rise to modern Teratology or the scientific discipline dedicated to the study of congenital malformations. Other profound social changes followed the thalidomide disaster, a medication that caused myriads of infants to be born with limb and other malformations. Soon, scientists also realized that most malformed embryos are unable to survive and are spontaneously aborted, a natural process called teratothanasia, to denote natural spontaneous prenatal thanasia or death. Moreover, those who are born with birth defects are likely to perish prematurely or lead a life burdened by chronic or serious disability. Birth Defects remain the leading cause of infant mortality in all developed societies without distinction of race, ethnicity, or wealth. Josef Warkany prevailed on the then National Arthritis Foundation to shift its attention toward children with "Birth Defects". From the onset, legal and other advisors favored the term "birth defect" rather than congenital "malformations" or "anomaly", perhaps because the term was considered to have a greater resonance. Since then, the March of Dimes Birth Defects Foundation has been dedicated to the prevention of "congenital" "anomalies" so broadly defined as to include premature births. Literature: Among common ancient myths or DELUSIONS persisting to our times, are concerns that maternal impressions, pleasant or not, may be capable of disrupting a developing baby. Such mythical ideas are upheld even by authors of widely read books. Art: A depictions by artists of various Malformations was published by Grosse Verlag Berlin 1986 under the tutelage of Drs. J. KUNZE and I. NIPPERT. Many artists, Velazquez in particular, painted portraits of individuals with bone disorders who gained political prominence. Note: Dysmorphism, Dysmorphology denotes altered proportions and shapes. Deformation conveys ideas of external mechanical forces altering morphogenesis. Dysplasia is used to describe abnormal "tissue" formation or growth. Neoplasia describes growth of "new" tissue. Plastic conveys the idea of an ability to take any shape. Elastic implies the above plus an ability to stretch or change volume. (part 4/4 which is preceded by birth, birthday and birth control) | Tags and Abbreviations Explained |
