There remains to be no transparent knowing of what explanations the good majority of human congenital malformations. and because in so much types of human affliction and pathology that but succeed prevention frequently awaits realizing of reason, it truly is regularly idea that an identical is correct of developmental aberrations. yet is that this real? For the rather few congenital malformations whose motives are basically environmental, it really is undeniable that their discovery has enabled prevention, yet no longer nec essarily instantly. It took a iteration from the time of the invention that maternal rubella used to be teratogenic to benefit tips on how to immunize opposed to it. a lot debate happened ahead of it was once preferred that thalidomide was once a teratogen, and in simple terms its elimination from the pharmacist's shelf and the tip of the epidemic of limb defects attributed to the drug overcame the final doubts.

Prevention has now not been accomplished via the invention of such reasons, as dramatic and innovative as a few of them were, other than within the questionable experience of interference with replica via genetic coun seling or prenatal removal. yet this has no longer inhibited the romanticists.

The author currently uses a classification based on the morphology and pathology of the placenta (Rushton, 1978) rather than of the embryo or fetus, although abnormalities of the latter are recorded. Three major groups are recognized: I. 4 weeks. II. 1 weeks. III. 6 weeks. In an un selected population approximately two-thirds of cases will fall into groups I and II, the remainder into group III or an unclassifiable category. It is 23 24 D. I.
