dysmaturity

dysmaturity

 [dis″mah-choor´ĭ-te]
the condition in a fetus of being small or immature for gestational age with malnourishment and evidence of chronic stress in utero; usually seen in a postterm pregnancy.
pulmonary dysmaturity Wilson-Mikity syndrome.

dys·ma·tu·ri·ty

(dis'mă-chūr'i-tē),
Syndrome of an infant born with relative absence of subcutaneous fat, wrinkling of the skin, prominent finger and toe nails, and meconium staining of the infant's skin and of the placental membranes; often associated with postmaturity or placental insufficiency.

dysmaturity

A nonspecific term used for various conditions.
(1) Disordered development—e.g., of a foetus; maldevelopment appears preferable.
(2) Postmaturity; postmaturity syndrome.
(3) The condition of being small or immature for gestational age, said of foetuses that are the product of a pregnancy involving placental dysfunction; immature and small for gestational age are both terms that are better understood.
(4) Failure of an organism to develop or achieve structural or functional maturity; immaturity appears preferable.
(5) Placental dysfunction.

Given the confusing overlap of varying definitions, it is best unused in the working medical parlance.

dys·ma·tu·ri·ty

(dis'mă-chŭr'i-tē)
Syndrome of an infant born with relative absence of subcutaneous fat, wrinkling of the skin, prominent finger and toe nails, and meconium staining of skin and placental membranes; often associated with postmaturity or placental insufficiency.

Cysts may be large and identified grossly; there may be an increase in density of syncytial knots or in cytotrophoblast clustering within the villous stroma [2,16], as well as placental dysmaturity [17].
Currently, we need a good indication or a favorable cervix, often ignoring those who have an unfavorable cervix until they are very postdates with placental dysmaturity and a higher chance of fetal intolerance of labor and cesarean delivery.

Except a single case documented by Campbell in 2009 in which a GDM patient with preeclampsia on Metformin had intrauterine death and the placental morphology showed pronounced changes such as villous dysmaturity, chorioamniotis, villi fibrosis.20
It is recommended that the term delayed villous maturation be used instead of villous maturation defect, variable villous maturation, or villous dysmaturity. This lesion is seen usually after 36 weeks and rarely before 34 weeks of gestation and is characterized by a monotonous villous population with reduced numbers of vasculosyncytial membranes for the period of gestation, as well as a continuous cytotrophoblast layer and centrally placed capillaries.

Additional features that were noted on histology in the HIV-positive group included evidence of meconium exposure (n=10), focal infarct (n=1), focal decidual vasculopathy (n=1), dysmaturity (n=3), fetal thrombotic vasculopathy (n=1), chorangiosis (n=1), intervillous thrombus (n=2) and intervillous haemorrhage (n=3); and in the HIV-negative group, infarcts (n=2), decidual vasculopathy (n=1) and dysmaturity (n=2).

It is known that as pregnancy extends post-term, the incidence of placental insufficiency and foetal postmaturity (dysmaturity) increases rapidly as a consequence of reduced respiratory and nutritive placental function (27).
