Mirror syndrome, triple edema or Ballantyne syndrome is a rare disorder affecting pregnant women. It describes the unusual association of fetal and placental hydrops with maternal preeclampsia. [1] The name "mirror syndrome" refers to the similarity between maternal edema and fetal hydrops. It was first described in 1892 by John William ...
Fetal abnormalities are conditions that affect a fetus or embryo, are able to be diagnosed prenatally, and may be fatal or cause disease after birth. They may include aneuploidies, structural abnormalities, or neoplasms. Acardiac twin; Achondrogenesis; Achondroplasia
Twin-to-twin transfusion syndrome (TTTS), also known as feto-fetal transfusion syndrome (FFTS), twin oligohydramnios-polyhydramnios sequence (TOPS) and stuck twin syndrome, is a complication of monochorionic multiple pregnancies (the most common form of identical twin pregnancy) in which there is disproportionate blood supply between the fetuses.
Vanishing twins occur in up to one of every eight multifetus pregnancies and may not even be known in most cases. [4] "High resorption rates, which cannot be explained on the basis of the expected abortion rate, suggest intense fetal competition for space, nutrition, or other factors during early gestation, with frequent loss or resorption of ...
Illustration of TRAPS pregnancy. On the left, the acardiac twin. The pump twin is on the right. Selective termination of the acardiac twin can reduce the risk of death of the pump twin. Twin reversed arterial perfusion sequence, also called TRAP sequence, TRAPS, or acardiac twinning, is a rare complication of monochorionic twin pregnancies. [1]
The twin reversed arterial perfusion, or T.R.A.P. sequence, results in an 'acardiac twin', a parasitic twin that fails to develop a head, arms and a heart.The parasitic twin, little more than a torso with or without legs, receives its blood supply from the host twin by means of an umbilical cord-like structure, much like a fetus in fetu, except the acardiac twin is outside the autosite's body.
Bovine spongiform encephalopathy (BSE), commonly known as mad cow disease, is an incurable and invariably fatal neurodegenerative disease of cattle. [2] Symptoms include abnormal behavior, trouble walking, and weight loss. [ 1 ]
