Premature rupture of the fetal membranes: Is the amnion the major determinant?

American Journal of Obstetrics and Gynecology, 2006
The objective of the study was to evaluate the relative contributions of amnion and chorion to the strength of fetal membranes and to correlate these findings with gestational age.Fetal membranes from 78 pregnancies were tested for biaxial puncture force using a blunt, instrumented probe with a low-force load cell connected through a load cell ...

Risk Factors for Preterm Premature Rupture of the Fetal Membranes

American Journal of Perinatology, 1990
Preterm premature rupture of the membranes (PPROM) is a significant cause of prematurity, accounting for approximately one third of preterm births in the United States. PPROM occurs in approximately 0.7-2% of all pregnancies nationally, and has a reported recurrence rate of 21%.

TESTS OF FETAL WELL-BEING IN PREMATURE RUPTURE OF MEMBRANES

Obstetrics and Gynecology Clinics of North America, 1992
In summarizing the published data on the use of amniocentesis and fetal biophysical assessment in managing patients with PROM the following conclusions may be drawn: 1. Both amniocentesis and fetal biophysical assessment are reasonably good methods to predict the fetus who is doing well and could therefore safely remain in utero, as well as the fetus ...

Apoptosis in the Chorion of Fetal Membranes in Preterm Premature Rupture of Membranes

American Journal of Perinatology, 2008
We sought to determine if apoptosis in the chorion of fetal membranes was increased in patients with preterm premature rupture of membranes (PPROM) with histological chorioamnionitis. Using the TUNEL (terminal uridine deoxynucleotidyl transferase dUTP nick-end labeling) method (ApopTag Plus kit; Oncor, Gaithersburg, MD), apoptosis was quantified.

Fetal Weight and Premature Rupture of the Membranes in Preterm Delivery

Asia-Oceania Journal of Obstetrics and Gynaecology, 1985
AbstractOne hundred and seven pregnant women who delivered babies before 38 weeks of gestation were studied. There were 44 patients (41.1%) with premature rupture of the membranes (PROM) while 63 patients (58.9%) not. The preterm delivery were responsible for 58.3% of the perinatal mortality.

Antibiotics and the management of preterm premature rupture of the fetal membranes

Clinics in Perinatology, 2001
Preterm premature rupture of membranes remains an important cause of preterm birth and neonatal morbidity and mortality. Although the underlying pathophysiology remains largely undefined, subclinical infection has been implicated both in the mechanism of membrane rupture and the resultant neonatal morbidity.

Fetal immune response following prematurely ruptured membranes

American Journal of Obstetrics and Gynecology, 1976
Concentrations of immunoglobulins (Ig)A1, and IgA2, IgD, IgE, IgG, and IgM have been determined in cord blood, amniotic fluid, and maternal serum in a group of patients with a history of prematurely ruptured membranes (PRM) prior to the onset of labor and in a control group of patients undergoing normal delivery and without a history of infection ...

Fetal Biophysical Profile and the Effect of Premature Rupture of the Membranes

Obstetrics & Gynecology, 1986
A retrospective study of 1151 fetal biophysical profiles and scores associated with good pregnancy outcome was conducted over a three-year period in the author's institution. Normal fetal biophysical activities and scores were determined throughout gestation from 25 to 44 weeks in patients with intact membranes, and compared with profiles and scores of

Premature Rupture of Fetal Membranes Changes in Collagen Type

Acta Obstetricia et Gynecologica Scandinavica, 1988
AbstractCollagen from the chorioamnion units from premature and term pregnancies was solubilized by limited pepsin digestion and subjected to SDS‐PAG electrophoresis. Collagen types were quantitated by densitometry. It was found that collagen type III decreases and collagen type V tends to increase as gestational age advances.

The role of proteomics in the assessment of premature rupture of fetal membranes

Clinica Chimica Acta, 2005
The presence and integrity of amniotic fluid is fundamental for the normal development of the human fetus during pregnancy. Its production rate changes throughout pregnancy and is mainly related to the functions of the different fetal, placental and amniotic compartments.
