“…Specifically in Uberaba city, Southeast of Brazil, in the same census of 2010, the rate of mixed amounted to 28.0% (21) , in other words a difference of 35.1% regarding the whole Brazilian population. Because of regional ethnic differences among populations in the same country, some authors have established reference charts for fetal biometrical parameters to specific regions (14, 22) .…”

ObjectiveTo establish reference charts for fetal biometric parameters in a non-selected risk population from Uberaba, Southeast of Brazil.MethodsA retrospective cross-sectional study was performed among 5656 non-selected risk singleton pregnant women between 14 and 41 weeks of gestation. The ultrasound exams were performed during routine visits of second and third trimesters. Biparietal diameter (BPD) was measured at the level of the thalami and cavum septi pellucidi. Head circumference (HC) was calculated by the following formula: HC = 1.62*(BPD + occipital frontal diameter, OFD). Abdominal circumference (AC) was measured using the following formula: AC = (anteroposterior diameter + transverse abdominal diameter) × 1.57. Femur diaphysis length (FDL) was obtained in the longest axis of femur without including the distal femoral epiphysis. The estimated fetal weight (EFW) was obtained by the Hadlock formula. Polynomial regressions were performed to obtain the best-fit model for each fetal biometric parameter as the function of gestational age (GA).ResultsThe mean, standard deviations (SD), minimum and maximum of BPD (cm), HC (cm), AC (cm), FDL (cm) and EFW (g) were 6.9 ± 1.9 (2.3 – 10.5), 24.51 ± 6.61 (9.1 – 36.4), 22.8 ± 7.3 (7.5 – 41.1), 4.9 ± 1.6 (1.2 – 8.1) and 1365 ± 1019 (103 – 4777), respectively. Second-degree polynomial regressions between the evaluated parameters and GA resulted in the following formulas: BPD = –4.044 + 0.540 × GA – 0.0049 × GA2 (R2 = 0.97); HC= –15.420 + 2.024 GA – 0.0199 × GA2 (R2 = 0.98); AC = –9.579 + 1.329 × GA – 0.0055 × GA2 (R2 = 0.97); FDL = –3.778 + 0.416 × GA – 0.0035 × GA2 (R2 = 0.98) and EFW = 916 – 123 × GA + 4.70 × GA2 (R2 = 0.96); respectively.ConclusionReference charts for the fetal biometric parameters in a non-selected risk population from Uberaba, Southeast of Brazil, were established.

Background Terminal duplication on chromosome 15q is a rare chromosomal variation. Affected individuals show similar features such as growth dysplasia or the development of frontal bossing, body deformities, facial abnormalities, and genitourinary or cardiovascular disorders. However, it is not yet clear whether such 15q repeats lead to identifiable patterns of clinical abnormalities. Therefore, the purpose of this study was to analyze the prenatal diagnostic results and clinical manifestations of a fetus with 15q duplication and to summarize the literature. Methods The case was a fetus at 28 weeks of gestation. The risk of Down syndrome from second‐trimester screening was 1/140. Prenatal ultrasound and amniocentesis were performed, and chromosomal microarray analysis (CMA) was used for genetic analysis. Results The fetus had abnormal clinical features, including intracardiac echogenic focus in the left ventricle, an aberrant right subclavian artery, and growth delay. The fetal chromosomal karyotype was 46,XX,15q?,12q?,21pstk+, and CMA revealed a 10.163 Mb duplication at 15q24.3‐q25.3. The couple chose to terminate the pregnancy after careful consideration. Conclusions The combination and rational application of cytogenetics technology and molecular genetics technology such as CMA will open up the field of clinical application and provide useful genetic counseling for parents of fetuses carrying such chromosomal duplications.
