OBJECTIVE: To compare perinatal and maternal outcome between induced and spontaneous small-for-gestational-age (SGA) neonates at term and preterm deliveries. STUDY DESIGN: A cross-sectional study was designed and two groups were identified at each gestational age: study group - SGA neonates born after induction of labor, comparison group - SGA neonates ...

OBJECTIVE: Fasting during pregnancy stimulates preterm delivery in animals and increases women's risk for preterm delivery. Fasting stimulates hypothalamic corticotropin-releasing hormone production in animals. Elevated maternal corticotropin-releasing hormone concentrations are associated with preterm birth. We hypothesized that prolonged periods without food during pregnancy increase maternal corticotropin-releasing hormone concentrations, which lead ...

Currently, preterm labour is treated with tocolytic agents and prenatal steroids until the 34th week of gestation only. Our objective in this study was to assess this practice. Seven-year records of all preterm infants born in our institution at 34--36 weeks of gestation, were evaluated retrospectively. All babies, born in ...

Preterm birth is the leading cause of infant mortality in industrialised societies. Its incidence is greatly increased among the socially disadvantaged, but the reasons for this excess are unclear and have been relatively unexplored. We hypothesise two distinct sets of causal pathways and mechanisms that may explain social disparities in ...

Preterm birth is currently the most important problem in maternal-child health in the United States. Epidemiological studies have suggested that two factors, maternal stress and maternal urogenital tract infection, are significantly and independently associated with an increased risk of spontaneous preterm birth. These factors are also more prevalent in the ...

Preterm premature rupture of membranes (PPROM) results initially from damage to collagen in the chorioamnion leading to a tear in the membrane. Tissue-damaging molecules called reactive oxygen species (ROS) are capable of damaging collagen in the chorioamnion that could lead to PPROM. This hypothesis is supported by epidemiological studies linking ...

Schierlitz L - - 2001
BACKGROUND: Spontaneous preterm premature rupture of the membranes occurring before 20 weeks' gestation carries a perinatal mortality of approximately 82% and potential for considerable morbidity for mother and fetus. This is in contrast to amniotic fluid leakage after second-trimester amniocentesis, when the prognosis is usually good. CASES: We report three ...

Up to 30% of mothers develop acute pyelonephritis if asymptomatic bacteriuria is untreated. Asymptomatic bacteriuria may have a role in preterm birth or it may be a marker for low socioeconomic status which is associated with low birth weight. The objective of this review was to assess the effect of ...

OBJECTIVES: The mechanisms by which microbial invasion of the amniotic cavity leads to membrane weakening and rupture are poorly understood. Recently, endogenous host enzymes have been implicated in this process. Matrix metalloproteinases are a family of potent enzymes that degrade components of the extracellular matrix. Collagen type I provides the ...

BACKGROUND: Reduction amniocentesis is used in cases of severe polyhydramnios to decrease maternal discomfort and the risk of preterm labor. In a MEDLINE search (1966 to present, English language, keywords: amniocentesis, chorioamnionitis), no report of Candida chorioamnionitis after serial reduction amniocentesis exists. CASE: A 29-year-old primigravida with a history of ...
