OBJECTIVE: To test the hypothesis that the risk of neonatal morbidity among late-preterm twins is similar to that of late-preterm singletons. METHODS: We conducted a retrospective cohort study of all women with twin or singleton pregnancy who gave birth during the late-preterm period in a single tertiary center between 2008 and 2015. Neonatal outcomes of low-risk, late-preterm twins were compared with those of low-risk, late-preterm singletons. The primary outcome was the same primary composite respiratory morbidity variable that was used in the randomized controlled trial of Gyamfi-Bannerman et al on the administration of antenatal corticosteroids during the late-preterm period...

OBJECTIVE: To report the outcome of dichorionic (DC) triplet pregnancies reduced to DC twins by laser ablation of the pelvic vessels of one of the monochorionic twins. METHODS: Intrafetal laser embryo reduction (ER) from DC triplet to DC twins was carried out in 61 pregnancies at 11(+0) - 14(+3) weeks' gestation. Pregnancy outcome was examined and compared to previous studies in DC triplets managed expectantly or by ER to twins or singleton with fetal intracardiac injection of potassium chloride (KCl)...

Intrauterine growth restriction in late pregnancy can contribute to adverse long-term metabolic health in the offspring. In the present study we used an animal (sheep) model of maternal dietary manipulation in late pregnancy, combined with exposure of the offspring to a low-activity, obesogenic environment after weaning, to characterise the effects on glucose homeostasis. Dizygotic twin-pregnant sheep were either fed to 60% of requirements (nutrient restriction (R)) or fed ad libitum (~140% of requirements (A)) from 110 days gestation until term (~147 days)...

BACKGROUND: Primary invasive cutaneous aspergillosis is a rare fungal infection that occurs mostly in immunocompromised patients. Newborns of very low birth weight present a high risk for this type of infection due to an immaturity of the cutaneous barrier and of the immune system. CASE PRESENTATION: We describe here a case of simultaneous invasive cutaneous aspergillosis in two preterm twins. Two male preterm bichorionic biamniotic twins (A & B) were born at a general hospital by spontaneous normal delivery at 24 weeks and 6 days of gestation...

BACKGROUND: Precipitate labour is related to the appearance of postpartum haemorrhage due to posterior uterine atony. However, preventive measures that may be effective in reducing blood loss in this type of delivery are still unknown. Therefore, the objective of this study was to determine the risk factors associated with blood loss produced in precipitate labour. METHODS: This was an observational, analytical retrospective cohort study based on a total sample of 742 women with vaginal delivery whose duration was less than 180 minutes, during the period 2010-2014...

BACKGROUND: Fetoscopic LASER coagulation of the placental anastomoses has changed the prognosis of twin-twin transfusion syndrome. However, the prematurity rate in this cohort remains very high. To date, strategies proposed to decrease the prematurity rate have shown inconclusive, if not unfavourable results. METHODS: This is a randomised controlled trial to investigate whether a prophylactic cervical pessary will lower the incidence of preterm delivery in cases of twin-twin transfusion syndrome requiring fetoscopic LASER coagulation...

Sex chromosome translocations are unique and must be considered separately from translocations between autosomes. Here, we describe the first prenatal case of one twin fetus with an unbalanced translocation between chromosome Y and chromosome 15, presenting a 46,XY,der(15)t(Y;15) karyotype. The other twin had a normal 46,XY karyotype. Cytogenetic analysis of the parental chromosomes revealed that the father had a normal 46,XY karyotype, whereas the mother exhibited a 46,XX,der(15) t(Y;15) karyotype. Thus, the proband inherited this translocation from the mother...

OBJECTIVE: To compare levels of β-hCG and estradiol collected during the first trimester in singleton and twin pregnancies following assisted reproduction technologies (ART). METHODS: We prospectively evaluated 50 singleton and 47 dichorionic twin pregnancies that eventually ended in live births. Patients were recruited from a single ART center with standard treatment protocols followed by fresh embryo transfers. Hormone measurements were performed within a narrow gestational age range and analyzed in a single laboratory thus minimizing inter- and intra-assay variability...

Several phenomena in contemporary perinatology create challenges for analyzing pregnancy outcomes. These include recent increases in iatrogenic delivery at late preterm and early term gestation which are incongruent with the belief that stillbirth and neonatal death risk decrease exponentially with advancing gestational age. Perinatal epidemiologists have also puzzled over the paradox of intersecting birth weight- and gestational age-specific perinatal mortality curves for decades. For example, neonatal mortality rates among preterm infants of women who smoke are substantially lower than neonatal mortality rates among preterm infants of non-smoking women, whereas the reverse pattern occurs at term gestation...

Two cases of devastating fetal malformations associated with vanished monochorionic twins were identified upon review of pathology files. A 35-year-old G1P0 woman and 36-year-old G3P1 woman were both diagnosed with an intrauterine twin gestation via transvaginal ultrasound at 10 weeks. The spectrum of fetal anomalies ranged from omphalocele, bilateral upper extremity, and unilateral lower extremity hypoplasia, to craniofacial malformation with diaphragmatic hernia. On histopathologic examination, the placentas demonstrated vascular anastomoses between the surviving co-twin and the "vanished" fetal sac...

Monozygotic twins with discordant karyotypes for trisomy 13 are rare. We report a case of a spontaneously conceived pregnancy who presented with first-trimester ultrasound finding of umbilical cord cyst and increased nuchal translucency in Twin A and no abnormalities in Twin B. Amniocentesis revealed 47,XY,+13 karyotype in Twin A and 46,XY karyotype in Twin B. Selective fetal reduction was performed for Twin A. Twin B was delivered at 32 weeks gestation with normal phenotype. Peripheral blood karyotype revealed 15% mosaicism for trisomy 13 and skin fibroblast revealed 46,XY karyotype...

OBJECTIVES: Women from the Philippines form one of the largest immigrant groups to North America. Their newborns experience higher rates of preterm birth (PTB), and separately, small-for-gestational age (SGA) birth weight, compared with other East Asians. It is not known if Filipino women are at elevated risk of concomitant PTB and severe SGA (PTB-SGA), a pathological state likely reflective of placental dysfunction and neonatal morbidity. METHODS: We conducted a population-based study of all singleton or twin live births in Ontario, from 2002 to 2011, among immigrant mothers from the Philippines (n=27 946), Vietnam (n=15 297), Hong Kong (n=5618), South Korea (n=5148) and China (n=42 517)...

Dietary supplementation of n-3 PUFA decreases the luteolytic PGF2α and improves the pregnancy rate in the dairy cow. However, its effect in the goat is not known. Accordingly, we studied the effect of supplementation of n-3 PUFA rich Fish oil (FO) on different reproductive events in the goat. Cycling goats (n = 30) were divided into two equal groups and fed an isocaloric and isonitrogenous diet supplemented with either FO (TRT; n = 15) or palm oil (PO) (CON; n = 15) @ 0.6 mL/kg body weight for 72 days during the breeding season...

Craniopagus is a very rare congenital anomaly that tends to affect females more often than males. It is classified as partial or total. Most affected twins are either stillborn or die during the perinatal period. Those who survive birth should undergo detailed radiological evaluations soon after their condition becomes stable so that the precise anatomy of the conjoined part can be defined and surgery can be planned in detail by a multidisciplinary team. Recommendations for decreasing the risk of unsuccessful surgery include performing surgery on an elective basis after extensive preoperative radiological evaluations as well as when the twins are at an acceptable age and weight for a complex surgical separation, generally as staged procedures...

Massive perivillous fibrinoid deposition (MFD) and maternal floor infarction (MFI) are lesions of unknown etiology associated with poor perinatal outcomes, including fetal intrauterine growth restriction and neurodevelopmental injury, high risks of pregnancy loss, and recurrence in subsequent gestations. MFI comprises massive intervillous fibrinoid deposition concentrated at the maternal floor. MFD is a similar lesion but is diffuse within the parenchyma. MFD/MFI lesions represent a spectrum of severity of cloak-like perivillous fibrinoid deposition, and there is mounting evidence that, often, they represent sequelae of immune-mediated phenomena and/or an imbalance in factors that normally maintain the fluidity of blood in the maternal space...
