Thalidomide remains one of the world's most notorious drugs due to the severe birth defects it induced in children between 1957 and 1962. (hindawi.com)
Surprisingly how thalidomide causes birth defects and how it acts in the treatment of clinical conditions are still far from clear. (hindawi.com)
The purpose of this review is to look at the recent work carried out into understanding how thalidomide causes birth defects, it's molecular targets and the challenges that remain to be elucidated. (hindawi.com)
However soon after the drug's release in Europe reports linked thalidomide to causing peripheral neuropathy in adult patients (which prevented its licensing and general release in the USA) as well as being behind the occurrence of a high and sudden increase of rare birth defects [ 3 , 5 - 8 ]. (hindawi.com)
The range and type of birth defects seen were unprecedented with the most striking and stereotypic feature being phocomelia, where the handplate remains but the proximal elements are missing or very short. (hindawi.com)
Dr. Kelsey undoubtedly prevented an epidemic of thalidomide-induced birth defects in the USA and for her efforts was subsequently given the President's Award for Distinguished Federal Civilian Service by President John F. Kennedy in 1962 [ 4 ]. (hindawi.com)

In an article published in 1985 warning about potential health dangers posed by the methanol from aspartame, 1 I stated that the scientific literature contained no studies addressing the critical question as to whether aspartame or methanol would cause birth defects. (wnho.net)
I was incorrect in saying that, but only because I was purposefully prevented from seeing a key FDA memo dated September 11, 1978 describing the details of birth defects and serious developmental brain damage found in the offspring of laboratory rabbits whose mothers had been fed aspartame during pregnancy. (wnho.net)
In both rabbit studies, aspartame appeared to cause birth defects. (wnho.net)
Like most of the scientific community, I had no idea that aspartame had tested positive for producing neural tube birth defects. (wnho.net)
Of the several million chemicals, pesticides and herbicides now in use, only an exceedingly small percentage have ever tested positive for causing birth defects. (wnho.net)
Barely 800 chemicals are known teratogens, producing birth defects in laboratory animals, and only about twenty of these are known to cause birth defects in the human. (wnho.net)
It was not until 20 years after the 1978 FDA memo that methanol was first tested again and found to cause neural tube birth defects in rats 626 and eventually in many other species of laboratory animal. (wnho.net)
Although it was many years before the details could be determined with any certainty, it did not take a great deal of time for exposure to aspartame to adversely affect the rate of birth defects in the United States and its trading partner, the United Kingdom. (wnho.net)

A multiple birth is the culmination of one multiple pregnancy, wherein the mother gives birth to two or more babies. (wikipedia.org)
A multiple pregnancy may be the result of the fertilization of a single egg that then splits to create identical fetuses, or it may be the result of the fertilization of multiple eggs that create fraternal ("non-identical") fetuses, or it may be a combination of these factors. (wikipedia.org)
A multiple pregnancy from a single zygote is called monozygotic, from two zygotes is called dizygotic, or from three or more zygotes is called polyzygotic. (wikipedia.org)
