  Objective: To establish fetal biometry nomogram using percentilemethod based on normal population.   Methods: A descriptive retrospective study in order to establishfetal biometry nomogram using percentile method basedon normal population. Four fetal biometry measurement (BPD,HC, AC and FL) was collected from ultrasonography examinationresult in Fetomaternal Division Ultrasound Unit - AnggrekClinic and from medical record unit Dr. Cipto MangunkusumoGeneral Hospital, from January 2015 until April 2016. Databeing documented using case report form and being tabulatedusing Microsoft Excell 2011 Version 14.7.0 (161029). All datawere analyzed using SPSS 20.0 dan Matlab R2016a.   Results: There were 6169 pregnant women underwent fetalbiometry ultrasound within January 2015 - April 2016. Basedon inclusion criteria, 2798 (45%) were eligible as researchsample distributed from 12 until 42 wga. Due to evenly distributiondata, 2205 (78%) were distributed from 20 until 40 wgato develop fetal biometry nomogram. Most pregnant womenwere 28.9 years old (SD  5.74) in range of 21-30 (55%) yearsold. The youngest was 13 years old and the oldest was 45years old. Four fetal biometry were collected and distributedevenly using percentile method to establish fetal biometrynomogram. As for estimated fetal weight curve was developedby Hadlock C formula. Each biometry was calculated the 10th,50th and 90th centile curves according to gestational age. Thus,representing the fetal biometry and modified Hadlock C estimatedfetal weight nomogram based on normal population inJakarta.   Conclusion: Each biometry and modified Hadlock C estimated fetalweight were calculated in 10th, 50th and 90th centile curves accordingto gestational age represent fetal biometry nomogram based onnormal population in Jakarta.

Objectives The objective was to assess the composite neonatal morbidity (CNM) among diabetic women with sonographic estimated fetal weight (SEFW) at 10 to 90th versus >90th percentile for gestational age (GA). Study Design The inclusion criteria for this retrospective study were singleton pregnancies at 34 to 41 weeks, complicated by diabetes, and that had SEFW within 4 weeks of delivery. Odds ratios (ORs) with 95% confidence intervals (CI) were calculated. Results Among the 140 cohorts that met the inclusion criteria, 72% had SEFW at 10th to 90th percentile for GA, and 28% at >90th percentile. Compared with women with diabetes with last SEFW at 10th to 90th percentile, those with estimate > 90th percentile for GA had a significantly higher rate of CNM (13 vs. 28%; OR, 2.65; 95% CI, 1.07–6.59). Among 109 diabetic women who labored, the rate of shoulder dystocia was significantly higher with SEFW at >90th percentile for GA than those at 10th to 90th percentile (25 vs. 2%; p = 0.002); the corresponding rate of CNM was 29 versus 10% (p = 0.02). Conclusion Among diabetic women with SEFW > 90th percentile for GA, CNM was significantly higher than in women with estimate at 10 to 90th percentile. Despite the increased risk of CNM, these newborns did not have long-term morbid sequela.

Objective We compared the sensitivity and specificity of abdominal circumference (AC) alone versus estimated fetal weight (EFW) to predict small for gestational age (SGA) or large for gestational age (LGA) at birth. Study Design We searched the literature for studies assessing an ultrasonographic AC or EFW after 24 weeks to predict SGA or LGA at birth. Case series or studies including anomalous fetuses or multiple gestations were excluded. We computed the sensitivity, specificity, and positive and negative predictive values of any AC or EFW cutoff analyzed by at least two studies. Results We identified 2,460 studies, of which 40 met inclusion criteria (n = 36,519). Four studies assessed AC alone to predict SGA (n = 5,119), and six assessed AC to predict LGA (n = 6,110). Sixteen assessed EFW to predict SGA (n = 13,825), and 22 evaluated EFW to predict LGA (n = 18,896). To predict SGA, AC and EFW < 10th percentile have similar ability to predict SGA. To predict LGA, AC cutoffs were comparable to all EFW cutoffs, except that AC > 35 cm had better sensitivity. Conclusion After 24 weeks, AC is comparable to EFW to predict both SGA and LGA. In settings where serial EFWs are inaccessible, a simpler screening method with AC alone may suffice.

Background: Throughout the fourth week of embryonic development the umbilical cord (UC) is formed, which corresponds to the fifth to the twelfth weeks of gestation. Fetuses with intrauterine growth restriction (IUGR) have leaner UCs than fetuses of appropriate gestational age do, and the caliber of the umbilical vein decreases significantly, resulting in a worsening of the Doppler parameters of the umbilical artery in the mother. The goal of this study was to evaluate the significance of sonographic UC diameter in determining gestational age in third trimester in pregnant women. Methods: We conducted a comparative cross-sectional research on 300 pregnant women aged range between (20-35) years, singleton gestation, gestational age (3rd) trimester estimated from antenatal mothers last menstrual period (LMP), viable fetus, presenting to obstetrics and gynecology department at Tanta university hospital. Results: Highly statistically significant positive correlation between UC diameter and gestational age, BPD, FL, AC, AFI, and estimated fetal weight was found. The increase in UC diameter was positively and significantly correlated with the increase in gestational age and estimated fetal weight, indicating that those who have prolonged gestational age and estimated fetal weight are more likely to have wider UC diameter. Conclusions: The UC diameter (UCD) has the potential to be a valuable indicator of fetal growth, well-being, and perinatal outcome. Sonographic measurement of UC diameter could be an efficient method of measuring fetal growth and predicting gestational age (GA), particularly between 28-40 weeks GA. It is possible that abnormal UC diameter can be a strong indicator to identify antenatal mothers at risk for IUFD and poor fetal outcomes.

Цель исследования - оценка возможностей прогнозирования рождения маловесного для гестационного возраста доношенного ребенка по результатам ультразвукового исследования в третьем триместре беременности. Осуществлен ретроспективный анализ результатов обследования 1 151 одноплодной беременности с анатомически здоровым плодом, проведенного в 2015-2017 гг. в сроки 11+1-13+6 нед, 30+0-33+6 нед и 35+0-36+6 нед беременности. Срок беременности устанавливался по копчико-теменному размеру плода в сроки 11+1-13+6 нед беременности. При ультразвуковом исследовании в третьем триместре беременности расчет предполагаемой массы плода проводился по формуле Hadlock с учетом бипариетального размера, окружности головы и живота, длины бедра плода. Основным изучаемым исходом была масса доношенного новорожденного 10-го процентиля. 1 087 (94,44%) беременностей закончились рождением ребен ка массой ≥10-го процентиля: данные случаи были отнесены к группе сравнения. 64 (5,56%) случая с массой доношенного новорожденного 10-го процентиля составили группу исследования (маловесные для гестационного возраста). ROC-анализ установил хорошее качество модели прогнозирования рождения доношенного маловесного для гестационного возраста ребенка на основании показателей предполагаемой массы плода как при исследовании в сроки 30+0-33+6 нед беременности (AUC - 0,830, 95%-й доверительный интервал - 0,760-0,902), так и в сроки 35+0-36+6 нед беременности (AUC - 0,888, 95%-й доверительный интервал - 0,818-0,958). При проведении ультразвукового исследования в 30-34 нед беременности для достижения эффективного прогнозирования рождения доношенного маловесного для гестационного возраста ребенка с выбранной чувствительностью 80% пациенткам с предполагаемой массой плода менее 42-го процентиля может быть предложено повторное исследование в 35+0-36+6 нед беременности. В случае выявления предполагаемой массы плода менее 23-го процентиля при повторном исследовании беременная может быть отнесена к группе высокого риска рождения доношенного маловесного для гестационного возраста ребенка с повышенной вероятностью перинатальных осложнений. Повышение дородового выявления беременных с высоким риском рождения доношенного маловесного для гестационного возраста ребенка может быть достигнуто за счет проведения ультразвукового исследования в более поздние сроки беременности. Ключевые слова: ультразвуковое исследование, предполагаемая масса плода, маловесный для гестационного возраста, доношенный новорожденный, ultrasound, estimated fetal weight, small-for-gestational age, full-term newborn
