Adventures in the Science of the Superorganism

By  David Wallace-Wells It is not only possible, it has in fact happened that a woman who vaginally conceived a child, then vaginally delivered her, had Protective Services threaten to take the child when a maternity test showed she was not, in fact, the mother. Nor was she the mother of her second child, genetically. Or her third, whom she was still carrying throughout the dispute with her estranged boyfriend — the man who, those same tests proved, was definitively the father. Only later did Lydia Fairchild discover that the true mother of all three of her children was her twin — if  twin  is really the word for one human embryo more or less swallowed by another before birth. The eggs that produced those babies had been with Fairchild her whole life, but genetically they belonged to an unborn sister, unknown to her and even her parents, living on in small parts inside her — a phenomenon that poetic scientists have called “parasitic” or “vanishing” twins. These days, they tend to prefe...

This Man Failed A Paternity Test Due To His Vanished Twin’s DNA

Image
By  Dan Vergano A 34-year-old U.S. man is the first-ever reported case of a paternity test fooled by a human “chimera” — someone with extra genes absorbed from a nascent twin lost in early pregnancy. About  1 in 8  single childbirths are thought to have started as multiple pregnancies. Cells from these miscarried siblings are sometimes absorbed in the womb by a surviving twin — but are only rarely discovered by surprises such as the paternity-test puzzle. “Even geneticists are blown away by this,” Barry Starr, a geneticist at Stanford University, told BuzzFeed News. Last year, a Washington couple came to Starr, who answers the “ Ask a Geneticist ” questions on the website of the Tech Museum of Innovation in San Jose, California, looking for help with what appeared to be a mistake at a fertility clinic. The answer to their mystery points to a possible genetic loophole in standard paternity testing, Starr said — “one where we have no idea how big the problem is.” In June 2014, the parent...

Fetal Transference Technique

By: R.D. Wayne Scott, D.C. and Brent H. Babcock, D.C. SUMMARY OF NET PROCEDURE: This technique is for patients who have experienced NET and desire a great breakthrough concerning their relationship with a Vanishing Twin (VT) or others. This procedure has helped those who are a twin, triplet or have a VT. During development, there are a great deal of materials that are transferred between the fetuses in the uterus. The goal is to become congruent with all that was transferred to the patient. ACTUAL CLINICAL CASE AND RESULTS USING THIS PROCEDURE: A NET patient of 8 years, who had been treated concerning his VT, came in for treatment concerning his relationship with his wife. He was very upset about the terrible war with his spouse. The Fetal Transference Technique was used. There was a major break through concerning the difficulties in all his relationships, with the root of the issues being with the VT. The patient reported he was feeling much better and stated that the new techniques w...

Taking a Deeper Look at the Vanishing Twin Syndrome

By Teshna Beaulieu, DC |  Certified NET Practitioner 7 Maple Ave. Philmont, NY 12565 | 518-672-4019 |  teshnab@taconic.net Subject Covered by the Article: So many people have been affected by the loss of a Vanishing Twin. I have identified several categories describing the modus operandi of VTS survivors which can help someone clear all the ramifications caused by the trauma of losing a loved one so early in the human experience. Many times I have found that people have had the VTS come up in NET sessions relating to one or more of the aspects described below. However, I found that many aspects have3 not come up yet even though they may be affecting the person’s life. This is a way of exploring these aspects on purpose and clearing them independently of any other topic. Summary of the NET Procedure: This is a procedure containing many steps found useful to help a person feel better about themselves, freer to be who they are and have their needs met without fear of terrible consequences...

Am I a Survivor of a Vanished Twin?

Questions to Discover if You May be a Vanishing twin Survivor Vanishing Twin is a word that’s been used since 2003 to describe the fetus or embryo that was a twin, triplet or other multiple but died early in the pregnancy, leaving no detectable trace at birth or before. The remaining child born is called a Vanishing Twin survivor. This is also known as the vanishing twin phenomenon. There are millions Vanishing Twin survivors in the world today that share some common characteristics. Instructions Step1 See if you feel different from other people. Maybe you have a strange sensation that somehow you don’t really exist, you’re not really here or shouldn’t be here. Step2 Look back to see if you have suffered from depression most of your life, you’ve had long-term problems with food and eating and perhaps you’ve always feared abandonment and rejection. These are common, similar feelings of Vanishing Twin survivors. Step3 Understand that feelings of wanting...

A Hypothesis for the Aetiology of Spastic Cerebral Palsy: The Vanishing Twin

Written by Administrator Pharoah, P. D. The aetiology of spastic cerebral palsy (CP), in the majority of cases, is not known but the general consensus is that cerebral impairment occurs prepartum. In monochorionic twin pregnancies, death of one twin late in gestation is recognised as being an important risk factor for the surviving cotwin to have CP. It has been suggested that a a significant proportion of singletons with spastic CP may be the result of death of a cotwin in the second half of gestation. In this paper it is hypothesised that spastic CP unknown aetiology is the result of the death of a monochorionic cotwin and that the death of the cotwin may impair the neurological development of the survivor throughout gestation. If so, vanishing-twin syndrome, which is now a recognised phenomenon revealed by ultrasound examination in early pregnancy, is important in the aetiology of spastic CP.

The "Vanishing Twin": Ultrasonographic Assessment of Fetal Disappearance in the First Trimester

Landy, M.D., H., Weiner, M.D., S., Corson, M.D., S. Review of the sonographic findings of 1000 pregnancies with viable gestations in the first trimester revealed a minimum incidence of twinning of 3.29%. Of these, 21.9% demonstrated the “vanishing twin” phenomenon, often with associated bleeding, but with a good prognosis for the remaining fetus. Ovulation induction did not appear to alter these data. The sonographic criteria for “vanishing twin” are discussed. The incidence of multiple gestation is 3.29% to 5.39%, higher than previously believed. (Am J Obset Gynecol 1986;155:14-9.)

Human Chorionic Gonadotropin Rise in the Normal and Vanishing Twins Pregnancies

Kelly, M.D., M. P. Results: A vanishing twin occurred in one third of the twin pregnancies. Forty-six percent of these losses occurred after fetal heart activity had been established. Conclusions: Vanishing twin phenomenon occurred in a large proportion of twin pregnancies in this infertility population. Fetal heart activity was not a reliable predictor of continuing fetal viability in early twin gestation. Vanishing twin conceptions were characterized by a slower rate of rise of hCG than normally progressing twin pregnancies. Fertil Steril 56:211, 1991 The twin resorption rate of 320.5% in this study is consistent with previous reports.

The Vanishing Twin: Morphologic and Cytogenetic Evaluation of an Ultrasonographic Phenomenon

Rudnicki, M., Vejerslev, L.O., Junge, Jette Abstract. Twin pregnancy was observed by ultrasonographic examination in the 6th week of gestation. After singleton term delivery a thickening of the membranes opposite to the main placenta showed degenerated chorionic villi embedded between one layer of amnion and chorion; no fetal parts were observed. Villus cells from both placentas were mainly deploid; 2 of 30 were tetraploid. Marker analysis was consistent with duplication of a normal conception diploid chromosome complement as the mechanism for tetraploidy. Postconceptional nondisjunction leading to tetraploidy in one twin conceptus may explain demise in early pregnancy. Tetraploidy observed by chorionic villus biopsy most be confirmed by amniocentesis before interruption of the pregnancy is considered. Gynecol Obstet Invest 1991;31:141-145 At birth the only remnants of a vanishing twin may be fibrous thickening of part of the membranes. The possible difference between chromosome consti...
