In a sample of 22,922 births in Copenhagen, the author found that this cord abnormality was no more common in the unfolded presentation than in the occipital presentation, namely, in the anterior-cranial in 19.6%, in the frontal in 22.2%, in the facial in 20.3%, while in the occipital in 22.1%.

The complex method of antenatal diagnostics of the cord entanglement round the body of the fetus is elaborated. It includes echography, color Doppler mapping, dopplerometry and actocardiography. On the basis of the data received the system of prognosing and estimating the severity of feta l hypoxia in the end of the third trimester pregnancy is suggested, that allows to choose the correct tactics of pregnancy and delivery management in different rates ofcord entanglement. The use o f this method made it possible to rise the effectiveness of antenatal diagnostics of this gestational complication from 23,5% to 79,4%, to decrease the frequency of postnatal asphyxia to 46,1% and, therefore, to avoid intra- and postnatal loss.

Monoamniotic twin pregnancy is a rare type of twin pregnancy which poses risk of cord entanglement and sudden death of either one or both fetuses. The role of antenatal surveillance by Ultrasound Doppler for umbilical cord and ultrasonic evidence of cord entanglement or knotting may predict the pregnancy outcome but yet unavoidable. The discussion will include antenatal surveillance in this rare type of pregnancy.

Abstract BackgroundThe outcome of in vitro fertilization-embryo transfer is often determined according to follicles and estradiol levels following gonadotropin stimulation. However, there is no accurate indicator to predict pregnancy outcome, and it has not been determined how to choose subsequent drugs and dosage based on the ovarian response. This study aimed to make timely adjustments to follow-up medication to improve clinical outcomes based on the potential value of estradiol growth rate. MethodsSerum estradiol levels were measured on the day of gonadotrophin treatment (Gn0), four days later (Gn4), seven days later (Gn7), and on the trigger day (HCG). The ratio was used to determine the increase in estradiol levels. According to the ratio of estradiol increase, the patients were divided into four groups: group A1 (Gn4/Gn0≤6.44), group A2 (6.44˂Gn4/Gn0≤10.62), group A3 (10.62˂Gn4/Gn0 ≤21.33), and group A4 (Gn4/Gn0>21.33); group B1 (Gn7/Gn4≤2.39), group B2 (2.39˂Gn7/Gn4≤3.03), group B3 (3.03˂Gn7/Gn4≤3.84), and group B4 (Gn7/Gn4>3.84). We analyzed and compared the relationship between data in each group and pregnancy outcome. ResultsIn the statistical analysis, the estradiol levels of Gn4 (P = 0.029, P = 0.042), Gn7 (P< 0.001, P = 0.001), and HCG (P< 0.001, P = 0.002), as well as the ratios of Gn4/Gn0 (P = 0.004, P = 0.006), Gn7/Gn4 (P = 0.001, P = 0.002), and HCG/Gn0 (P< 0.001, P< 0.001) both had clinical guiding significance, and the lower one significantly reduced the pregnancy rate. The outcomes were positively linked to groups A (P = 0.040, P = 0.041) and B (P = 0.015, P = 0.017). The logistical regression analysis revealed that group A1 (OR = 0.440 [0.223–0.865]; P = 0.017, OR = 0.368 [0.169–0.804]; P = 0.012) and B1 (OR = 0.261 [0.126–0.541]; P< 0.001, OR = 0.299 [0.142–0.629]; P = 0.001) had opposite influence on outcomes. ConclusionMaintaining a serum estradiol increase ratio at least above 2.39 on Gn7/Gn4 may result in a higher pregnancy rate. When estradiol growth is not ideal, gonadotrophin dosage should be adjusted appropriately to ensure the desired outcome.

ABSTRACT The use of three-dimensional (3D) ultrasonography since the first trimester of pregnancy allows the diagnosis and follow-up of cord entanglement throughout the entire pregnancy and delivery. This technology permits a more accurate diagnosis when compared with two-dimensional (2D) ultrasonography or Doppler The vast majority of cord entanglements observed at the end of the first-trimester will persist during the entire pregnancy; delivery outcome is usually not affected by this finding except for cases in which multiple cord entanglement is diagnosed.

SUMMARY OBJECTIVE: We measured the level of pH gases in premature infants at birth, and examined the relationship between brain ultrasonography on the third and seventh day after birth. A case-control study conducted at the Neonatal Intensive Care Unit (NICU) of Shahid Akbar Abadi Hospital, Iran, during the years 2016-2017. METHODS: All premature infants who were admitted to NICU were enrolled in the current study. At birth, a blood gas sample was taken from the umbilical cord of the infants. On the third and seventh day after birth, an ultrasound of the brain of each neonate was performed by a radiologist. The umbilical cord was evaluated for blood gases in 72 neonates (mostly boys). RESULTS: Sixty-six newborns had normal sonography, and 16.7% (12 cases) had anomalies. A total of 75% of the 8 infants with intravenous bleeding were girls, which were significantly different from those in the non-hemodynamic group (62.5% male) (P 0.049). However, the type of delivery, mean weight, height, head circumference, the circumference of the chest, and Apgar score did not differ between the two groups. Mean pH, HCO3– and PCO2 in umbilical cord blood gas samples were not significantly different between the two groups with or without intraventricular hemorrhage (IVH). Although it was not related to gender and type of delivery in newborns CONCLUSION: Blood gases do not help in determining the occurrence of IVH in infants. Nevertheless, it is associated with immaturity and fetal age.
