Chorioamnionitis, also known as amnionitis and intra-amniotic infection (IAI), is inflammation of the fetal membranes (amnion and chorion), usually due to bacterial infection. [1] In 2015, a National Institute of Child Health and Human Development Workshop expert panel recommended use of the term "triple I" to address the heterogeneity of this ...
Constriction ring syndrome (CRS) is a congenital disorder with unknown cause. Because of the unknown cause there are many different, and sometimes incorrect, names. It is a malformation due to intrauterine bands or rings that produce deep grooves in (most commonly distal) extremities such as fingers and toes.
If there is too little amniotic fluid around the baby in the uterus, the baby can have trouble moving around in the uterus and its growth and temperature can be impacted. Low amniotic fluid can be caused by placental issues, high gestational blood pressure, some medications, as well as problems with the fetal kidney or urinary tract. [9]
Post-maturity syndrome is the condition of a baby born after a post-term pregnancy, first described by Stewart H. Clifford in 1954. [1] Post-maturity refers to any baby born after 42 weeks gestation, or 294 days past the first day of the mother's last menstrual period.
Often, testing of the amniotic fluid is normal, but a subclinical infection (too small to detect) or infection of maternal tissues adjacent to the amniotic fluid, may still be a contributing factor. In response to infection, the resultant infection and release of chemicals ( cytokines ) subsequently weakens the fetal membranes and put them at ...

Birth defects are divided into two main types: structural disorders in which problems are seen with the shape of a body part and functional disorders in which problems exist with how a body part works. [3] Functional disorders include metabolic and degenerative disorders. [3] Some birth defects include both structural and functional disorders. [3]
Amniotic fluid index (AFI) is a quantitative estimate of amniotic fluid [1] and an indicator of fetal well-being. It is a separate measurement from the biophysical profile. [1] AFI is the score (expressed in centimetres) given to the amount of amniotic fluid seen on ultrasonography of a pregnant uterus.
