INTRODUCTION: Inflammation might be an important underlying cause of preterm birth. Our aim is to explore whether vaginal administration α-lipoic acid reduces cervical inflammation and shortening after primary tocolysis. Matherials and Methods: Singleton pregnancies between 24-30 weeks remaining undelivered after hospitalization for preterm labor were randomly allocated to placebo (20 women, 15 analyzed) or vaginal ALA 400 mg daily (20 women, 17 analyzed) for 30 days. A cervical swab to quantify pro-inflammatory (IL1, IL2, IL6, IL8, TNFα) and anti-inflammatory (IL4, IL10) cytokines as well as transvaginal ultrasound cervical length measurement (CL) were performed before and after treatment...

BACKGROUND: Regional epidural analgesia is considered the gold standard for pain treatment in labour but the epidural catheter placement may be a difficult procedure because of the difficulty in anatomical landmarks palpation. These difficulties increase in pregnant women. Pre-procedure neuroaxial ultrasound may facilitate the procedure. METHODS: Prospectic randomized controlled study conducted in the Labour Ward. We randomized two groups of women undergoing epidural analgesia: Group A (28 patients), with loss of resistance technique and Group B (30 patients) with US assisted procedure...

Cortisol is a well-known glucocorticoid that can be used as a biomarker of hypothalamic-pituitary-adrenocortical activity. To explore basal cortisol physiology during pregnancy and infancy in Macaca nemestrina monkeys, hair was collected from a convenience sample of 22 healthy mother-infant dyads. Adult females were housed in pairs as part of a small breeding colony at the Washington National Primate Research Center and infants were reared in a specialized nursery. Maternal samples were collected from females during a pregnancy-detection ultrasound and immediately following labor and delivery...

We report 2 cases of true uterine artery aneurysms diagnosed during pregnancy. Both cases presented with nonspecific symptoms such as urethral obstruction, minimal vaginal bleeding and lower abdominal pain in the 2nd trimester. Both aneurysms were diagnosed by color Doppler ultrasound. In the first case labor was induced at 37 + 4 weeks of gestation. However, due to sudden fetal distress and maternal abdominal pain, an emergency Caesarean section was performed during labor, and 3 liters of intra-peritoneal blood were encountered upon laparotomy, secondary to a ruptured uterine artery aneurysm...

INTRODUCTION: Brain natriuretic peptide (BNP) is synthesized by human fetal membranes, both the amnion and chorion. This locally produced BNP inhibits the contraction of the human myometrium, contributing to the maintenance of myometrial quiescence during pregnancy. Reference values for NT-proBNP concentrations in amniotic fluid at different gestational ages have not been completely defined. We aimed to investigate the range of fetal NT-proBNP values in amniotic fluid in normal pregnancy between 17 and 41weeks of gestation...

BACKGROUND & PURPOSE: Paget-Schroetter Syndrome (PSS) is a rare condition of vein thrombosis that can manifest in upper extremity athletes and laborers. If diagnosed early, PSS can be managed and symptoms fully reversed. Venous Duplex Ultrasound (US) is the most commonly used modality to diagnose deep vein thrombosis (DVT). While US demonstrates high sensitivity and specificity for detecting DVT, This case describes the differential diagnosis process and management of a weightlifter with PSS...

OBJECTIVE: To evaluate the relationship between entanglement of umbilical cord around the fetal neck and adverse perinatal outcomes. METHODS: In this prospective cohort study, perinatal outcomes of 218 pregnancies complicated with nuchal cord (NC) (study group) were compared with 190 uncomplicated pregnancies (control group). Main outcome measures were umbilical cord pH values, APGAR scores and cesarean section (C/S) rates. Fetal distress was stated as an abnormal heart rate pattern on electronic fetal heart monitorization...

It was demonstrated that second- and third-trimester therapeutic termination of pregnancy (TOP) is feasible in cases with placenta previa. We report a 34-year-old woman with complex fetal malformations associated with placenta previa. An ultrasound examination at 21 weeks of gestation revealed fetal growth restriction (FGR) and complex fetal malformations associated with a placenta previa. After extensive information, the parents opted for careful observation. Thereafter, FGR gradually progressed and we observed arrest of end-diastolic velocity of the umbilical artery...

Preterm birth remains the most prevalent cause of neonatal morbidity. This study aimed to evaluate the diagnostic value of SDF-1α, resistin, secretory RAGE (sRAGE), and endogenous secretory RAGE (esRAGE) in preterm labor. A total of 211 pregnant women participated in the study. Group A contained 72 women between 22 and 36 weeks of gestation, with premature labor, who finally had preterm birth. Group B contained 66 women in labor between 37 and 41 weeks of gestation. Women in group A had lower SDF-1α and sRAGE levels than those in group B...

A 27-week fetus evaluated for bradycardia and hydrops was found to have anti-SSA-negative 2° atrioventricular block and ventricular tachycardia. A presumptive diagnosis of fetal long QT syndrome was made. Transplacental pharmacotherapy with intravenous magnesium and lidocaine restored sinus rhythm. At 30 6/7 weeks, the infant was delivered due to premature labor. Despite postnatal treatment with mexiletine and propranolol, she developed torsades de pointes. Ultimately, a de novo KCNH2 G628S mutation was diagnosed...

BACKGROUND: Five-to-eighteen percent of pregnancies worldwide end in preterm birth, which is the major cause of neonatal death and morbidity. Approximately 30% of the variation in gestational age at birth can be attributed to genetic factors. Genome-wide association studies (GWAS) have not shown robust evidence of association with genomic loci yet. METHODS: We separately investigated 1921 Norwegian mothers and 1199 children from pregnancies with spontaneous onset of delivery...

BACKGROUND: Choice of delivery route after previous cesarean delivery can be difficult because both trial of labor after cesarean delivery and elective repeat cesarean delivery are associated with risks. The major risk that is associated with trial of labor after cesarean delivery is uterine rupture that requires emergency laparotomy. OBJECTIVE: This study aimed to estimate the occurrence of uterine rupture during trial of labor after cesarean delivery when lower uterine segment thickness measurement is included in the decision-making process about the route of delivery...
