Vanishing Twin Blog

We recently (and quite unexpectedly) found out that we are expecting for the third time. Almost immediately after the positive pregnancy test, I was inundated with first trimester symptoms. Only this time, it was different. The nausea and fatigue were unlike anything I experienced with my first two pregnancies. I was queasy or throwing up all the time . I could barely move off of the couch. I was completely exhausted despite sleeping 10+ hours every night. And my belly? Holy cow, that baby bump came out of nowhere. Friends and family insisted I must be further along than I thought, but I had a different suspicion… I couldn’t shake the feeling that I might be pregnant with twins. The bump at only 8 weeks! I anxiously awaited my first doctor’s appointment. When the day finally arrived, I could hardly wait to sneak a peek at the little bean (or beans!) I held my breath as the ultrasound technician prodded around for what felt like an eternity. She spoke slowly as she pressed harder on m

Hong Kong (CNN)  A team of Hong Kong doctors has described an extremely rare medical occurrence: what appeared to be a pair of fetuses inside the body of a newborn girl. They were both joined to a placenta-like mass by umbilical cords. Each one had four limbs, skin, a ribcage, intestines and primitive brain tissue, according to a study published this month in the Hong Kong Medical Journal . It was “one of those very rare things that make the world stand still,” said Dr. Nicholas Chao, one of the surgeons who operated on the baby. He said he’d never seen anything like it before during his career in pediatric medicine. The unusual condition, known as “fetus-in-fetu,” is estimated to happen once in every half-million births but has been reported fewer than 200 times worldwide, according to the study published by Chao and his colleagues. The baby, weighing about 9 pounds, was born in November 2010 to a woman from mainland China. The little girl recovered well from the operation to remove t

Doctors in California have removed a tumour they have described as an “embryologic twin” deep inside the brain of a young woman. Yamini Karanam, 26, a PhD student in Indiana, had been experiencing difficulties with drowsiness, reading and concentration. The discovery was made when doctors performed a newly-developed form of surgery to remove the tumour. The growth, known as a teratoma, had bone and hair. Ms Karanam, a student at Indiana University, jokingly described the tumour to KNBC, a California TV station , as her “evil twin sister who’s been torturing me for the past 26 years”. The tumour was found in Ms Karanam’s corpus callosum. “This tumour was smack in the middle of that, so extremely deep in the brain,” Dr Hrayr Shahinian told the BBC. It was not until after she awoke from surgery that she realised the details of her condition. Ms Karanam told the BBC that her reaction to the news was subdued at first, but later, when the anaesthetics wore off, she became more surprised. “I

Link To Video A Kansas family is given the news of twins , only to find out they’ll most likely go home with just one newborn. Ian and Brittani McIntire were heartbroken when doctors told them that one of their unborn twins probably will die before he is born. Baby Mason McIntire has a hole in his heart and an abnormal brain. But the family said they are clinging to the knowledge that Mason is not alone in the womb. His unborn twin sister, Madilyn, is there to comfort him. On Tuesday, the family shared with their local news station a heartbreaking ultrasound image of baby Mason’s tiny hand clinging onto his sister’s fingers. Brittani said the ultrasound tech told her that her twins’ interactions are unusually kind and gentle, as if they know that Mason may not live long. It could very well be true. Scientific studies have found that unborn babies feel emotions like joy, anger and sadness in the womb long before they are born. “Most twins, when she’s trying to take pictures and stuff,

An infant in the womb is extremely open and sensitive to the energies that encompass her. She may experience her environment as joyous or traumatic, depending on the quality of feeling she receives from her mother. She is ordinarily deeply affected by the mother’s emotional, mental and physical state. She does not have a sense of being a separate individual, of having a separate identity. As a result, she does not recognize the difference between her mother’s experiences and her own experiences. “When mother is unhappy, that is how I feel” is commonly reported during prenatal regressions. For instance an infant responds to the emotional energy of an unhappy mother. Her reactions are experienced at a fundamental level, as body responses, rather than thoughts. She then forms an adaptation to the unpleasant atmosphere that envelopes her. This adaptation provides a way of coping with her mother’s emotional energies. Depending on her predisposition, she may adapt in one of various ways: by

Twins not only have a bestie from birth — they also live longer than singletons. And those two factors may be related, according to new University of Washington research. While twins have been subjects in countless studies that try to separate the effects of nature from nurture, a recent study in PLOS ONE is the first to actually look at what being a twin means for life expectancy. Analysis shows that twins have lower mortality rates for both sexes throughout their lifetimes. “We find that at nearly every age, identical twins survive at higher proportions than fraternal twins, and fraternal twins are a little higher than the general population,” said lead author David Sharrow, a UW postdoctoral researcher in aquatic and fishery sciences. The results suggest a significant health benefit for close social connections. The data comes from the Danish Twin Registry, one of the oldest repositories of information about twins. The authors looked at 2,932 pairs of same-sex twins who survived pa

You may think your body and mind are your own. In fact, you are a fusion of many organisms – including, potentially, another person. Words by David Robson, photography by Ariko Inaoka.

Your dad met your mum, they had some fun, and from a tiny fertilised egg you emerged kicking and screaming into the world. You are half your mum, half your dad – and 100% yourself. Except, that simple tale has now become a lot more complicated. Besides your genes from parents, you are a mosaic of viruses, bacteria – and potentially, other humans. Indeed, if you are a twin, you are particularly likely to be carrying bits of your sibling within your body and brain. Stranger still, they may be influencing how you act. “Humans are not unitary individuals but superorganisms,” says Peter Kramer at the University of



Thanks to a rare medical condition, a Washington state woman found out that pregnancy was not enough to prove motherhood; DNA testing indicated that she was, in fact, not the mother of her own children – so who was? During the course of a desperate battle to retain custody of her three children, it was discovered that her twin was the real biological parent. The twist? She, 26-year-old Lydia Fairchild, was her own twin. By the time Fairchild was 23 years old, she had given birth to two children and was pregnant with a third. Her relationship with the father had been rocky. They separated – not for the first time – and she found herself, at 26, a struggling, single mother; out of work and unable to support her kids. When she applied for government assistance, however, her world was shattered by an incredible revelation – one that led to criminal accusations and the impending prospect of losing her children to the state. In order to qualify for financial assistance in supporting her you

Examples of Chimeras           Dan Lipsker, MD, PhD ; Elisabeth Flory, MD ; Marie-Louise Wiesel, MD ; et al Background   Chimerism, especially in the absence of sexual ambiguity, is extremely rare in humans. We report the case of a 6-year-old boy whose skin pigmentary abnormalities revealed chimerism. Observations   The boy had no remarkable previous medical history, and he had normal intelligence and development. On examination, we found a disorder of the skin pigmentation that was difficult to categorize; there was a lighter-appearing skin patch in the median frontal area and also on one-half of the abdominal area, with a sharp midline demarcation. He also had 2 lighter Blaschko-linear bands on the lower extremities and an indefinable mixture of lighter and darker skin on the back and the lateral part of the trunk. It was not possible to ascertain by means of clinical examination of the patient, his parents, and his brother which of the 2 shades was his normal skin color. Because thi

  By GINA KOLATAMAY 12, 2005   Last month, when the champion American cyclist Tyler Hamilton was accused of blood doping, or transfusing himself with another person’s blood to increase his oxygen-carrying red cells, he offered a surprising defense: The small amount of different blood found mixed in with his own must have come from a “vanishing twin.” In other words, his scientific expert argued, Hamilton had a twin that died in utero but, before dying, contributed some blood cells to him during fetal life. And those cells remained in his body, producing blood that matched the dead twin and not Hamilton. Or perhaps it was his mother’s blood that got mixed in during fetal life. An arbitration panel did not believe those hypotheses and said there was a “negligible probability” that Hamilton was anything but guilty. The test, they concluded in a 2-1 decision, shows a blood transfusion and that meant that Hamilton was suspended from racing for two years; he is the first and only person in c
