Despite medical progresses, preterm birth retains its actuality in modern obstetrics and remains the leading cause of perinatal morbidity and mortality. The incidence of preterm birth is 10% in the entire deliveries. 1 It is stressed that severe mortality and morbidity occur in the deliveries before 34 th week of gestation. 2 When neonatal mortality rates are reviewed, we have observed that 83% of these rates correspond to the babies born before the completion of 37 th week of pregnancy. 3 Approximately 20-30% of the preterm births (i.e. 1-4% of all births) are caused by medical and obstetric reasons; while 70-80% of these births may be linked to spontaneous idiopathic reasons associated or not associated with premature rupture of membranes (PROM). 4 Preeclampsia, fetal distress, Fetal Growth Retardation (FGR), abruption placenta and fetal death may be referred to as the medical and obstetric causes. 5 The prediction and prevention of preterm births are among the major issues of obstetrics. Prediction and prevention of preterm births by determining the risk ABSTRACT Background: The objective of this study was to compare the Fetal Zone Depth (FZD) of fetal adrenal gland in term and preterm labor cases. Methods: Twenty nine preterm pregnant women at 29-36 weeks of gestation with single pregnancy admitted with the clinical diagnosis of preterm labor and the comparison group of 33 pregnant women at 37-40 weeks with term pregnancy were included in this study. FZD and Total Gland Depth (TGD) of fetal adrenal gland of the entire fetuses in sagittal plane were ultrasonographically measured and FZD/TGD ratios were calculated. Demographic and clinical features, laboratory findings and fetal adrenal gland FZD/TGD ratios were compared between the two groups. Results: No difference was found between the two groups in respect of age, number of pregnancies and delivery method (P >0.05); yet preterm birth history and duration of hospital stay were higher in preterm group (P <0.05). Fetal adrenal gland FZD/TGD ratio was statistically significantly higher in preterm group compared to the term group (55.4% ± 4.9 vs. 47.7% ± 5.6; P <0.001). Conclusion: The growth in FZ as a fetal adaptation mechanism in increased fetal stress in preterm labor cases was at a significant level. Once supported by more comprehensive studies, we think that this result would be beneficial in the prediction of preterm labor in clinical practice.
Hastalar normal, hafif kayg›, orta seviye kayg› ve fliddetli kayg› gruplar›na ayr›ld› ve 124 (%66.6) hastada kayg› saptand›. Kayg› hastalar›n›n oldu¤u grupta hastalar›n %95.9'unda hafif kay-g› bulundu. Hiçbir hasta fliddetli kayg›ya sahip de¤ildi. Özellikle Grup 1'in hasta oran›, %85 oran ile di¤er gruplardan daha fazlay-d›. Grup 3'teki hastalar›n ço¤u (%50), di¤er gruplara k›yasla normal olarak de¤erlendirildi. Sonuç: Gebelerin kayg› seviyeleri genellikle hafiftir ve daha önce do¤um yapm›fl ve a¤r› yaflamam›fl gebeler düflük kayg› seviyelerine sahiptir.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
