Esophageal atresia is a congenital medical condition (birth defect) that affects the alimentary tract. It causes the esophagus to end in a blind-ended pouch rather than connecting normally to the stomach. It comprises a variety of congenital anatomic defects that are caused by an abnormal embryological development of the esophagus.
During pregnancy, duodenal atresia is associated with increased amniotic fluid in the uterus, which is called polyhydramnios. [1] This increase in amniotic fluid is caused by the inability of the fetus to swallow the amniotic fluid and absorb it in their digestive tract. [citation needed]
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.
Polyhydramnios is a medical condition describing an excess of amniotic fluid in the amniotic sac.It is seen in about 1% of pregnancies. [1] [2] [3] It is typically diagnosed when the amniotic fluid index (AFI) is greater than 24 cm. [4] [5] There are two clinical varieties of polyhydramnios: chronic polyhydramnios where excess amniotic fluid accumulates gradually, and acute polyhydramnios ...
In fact, nearly all reported cases of sirenomelia also present with BRA.It is associated with childhood polycystic kidney disease which is autosomal recessive in origin [4] Other anomalies of the classic Potter sequence infant include a parrot beak nose, redundant skin, and the most common characteristic of infants with BRA which is a skin fold ...
The VACTERL association (also VATER association, and less accurately VACTERL syndrome) refers to a recognized group of birth defects which tend to co-occur (see below).This pattern is a recognized association, as opposed to a syndrome, because there is no known pathogenetic cause to explain the grouped incidence.
The infant may be seriously affected and have a variety of birth defects. Complications in the mother and fetus can include pre-eclampsia, anemia, miscarriage, low birth weight, still birth, congestive heart failure, impaired neurointellectual development, and if severe, congenital iodine deficiency syndrome.
Of the 660,000 congenital syphilis cases reported in 2016, 143,000 resulted in deaths of unborn babies, 61,000 deaths of newborn babies, 41,000 low birth weights or preterm births, and 109,000 young children diagnosed with congenital syphilis. [15] Around 75% were from the WHO's African and Eastern Mediterranean regions. [2]
