Background: Gestational age is estimated by last menstrual period. Many women are unaware of their last menstrual period due to irregular menses, conception in lactation amenorrhea and due to illiteracy. The best possible ante partum care and successful labor outcome always revolve around the accurate knowledge of gestational age determination, and is an important component of antenatal care Methods: This was a prospective observational study conducted in department of obstetrics and gynecology on 200 pregnant women in second and third trimester with singleton live fetus at Mahila chikitsalay, S.M.S. medical college, Jaipur, from June 2018 to December 2019. All women were subjected to USG for estimation of gestational age by placental thickness (measured at the level of umbilical cord insertion). Results: Mean placental thickness show linear positive correlation with head circumference (HC). (r=0.960, p<0.0001).Mean placental thickness show linear positive correlation with abdominal circumference (AC). (r=0.948,p<0.0001). Mean placental thickness show positive correlation with FL both have linear correlation(r=0.946,<0.0001). Mean placental thickness show linear positive correlation with estimated fetal weight (EFW). (r=0.926,p<0.0001) Conclusion: All fetal parameter FL, HC, EFW, BPD, AC and gestational age showing positive correlation with placental thickness. All parameter have linear relationship with placental thickness. Correlation may be different with different type of parameter. Keywords: Ultrasonography (USG), Placental thickness, Gestation age.

Background: Gestational Age (GA) is one of the most imperative parameters required for proper management in pregnancy. Routinely GA is estimated by sonography utilising Biparietal Diameter (BPD), Femur Length (FL), Abdominal Circumference (AC) and Head Circumference (HC). In any case, these parameters have some limitations. Hence, there is need to find other parameters that may complement the established fetal biometric parameters in predicting GA. The objective of the present study was to assess placental thickness in second and third trimester pregnancies and its relationship with fetal gestational age and its role in detecting LBW and IUGRMethods: A cross sectional prospective study was carried out in three hundred pregnant women between 13 to 40 weeks of gestation, who came for routine antenatal sonography. Placental thickness was measured along with routine parameters. Placental thickness was measured at the level of umbilical cord insertion by two-dimensional ultrasonography.Results: Correlation between the GA by LMP and Placental thickness by ultrasound was done by using Karl Pearson's Correlation(r). The values were expressed as mean + standard deviation. Correlation between placental thickness and gestational age was statistically significant as p value is <0.01. Placental thickness measured in millimetres increases with gestational age in second and third trimester.Conclusions: The correlation between the placental thickness and gestational age was linear and direct. Therefore, Placental thickness is used as a predictor for estimation of gestational age of the fetus in cases where LMP is not known and in detecting developing IUGR and low birth weight.

This study aimed to establish reference values of fetal transverse cerebellar diameter (TCD) in a Nigerian population. A cross-sectional convenience study was carried out between June 2013 and May 2014 in Enugu, Nigeria. The sonographic examinations were performed on 697 pregnant women with gestational ages between 14 and 40 weeks. The TCD measurements were obtained from the proximal outer margin to the distal outer margin of cerebellum. The women’s last menstrual period, femur length, biparietal diameter, head circumference, and abdominal circumference were also recorded. The mean (standard deviation) TCD increased from 13.6 (2.2) mm to 27.3 (2.6) mm and 28.9 (2.0) mm to 42.9 (2.0) mm in the second and third trimesters, respectively. The relationship of TCD with gestational age obtained from last menstrual period, femur length, biparietal diameter, head circumference, and abdominal circumference was determined. The TCD had a strong correlation with gestational age ( r = .93; P < .05). Reference values for TCD were established for those patients who attended this clinic. This is a likely data set to use for future research that could focus on similar practices and in other regions of the country for possible generation of a nationwide nomogram.

Background: Gestational age is a critical factor in the management, decision making and follow up of new born infants. Identification of gestational age especially within 48 hours of life is crucial for new born. Since decades attempts have been made to find an alternative measurement for gestational age and birth weight estimation of the newborns. Last menstrual period is an inexpensive method and potentially efficient for calculating gestational age. Objective of this study was to the present study aims to compare the gestational age by New Ballards score with LMP, in pre term babies.Methods: A total 150 pre term babies who are born to mothers remembering LMP were enrolled for the study group. During the study period new Ballard scoring was done for babies within 48hrs and Gestational age was compared with LMP. The collected data was analyzed by using SAS-6.50 version. Study design a prospective observational study was conducted over a period of one year from January 2018 till December 2018 at Rajarajeswari Medical College and Hospital, Bengaluru, IndiaResults: The New Ballard score is found to be significantly correlated with GA above 29 weeks (p<0.01). The LMP mean was 35±2.0 weeks. Total 60.6 % of the childbirth is lead to normal vaginal delivery. The analysis shows LMP were found to be strongly correlated with GA (p<0.01).Conclusions: LMP alone can be reliably used in assessing the gestational age and can be assessed more accurately and be confirmed with new Ballard’s scoring for preterm babies of >29 weeks.

Background: Ultrasonographic assessment of gestational age by using different foetal parameter such as BPD, FL, AC are highly reliable in first and second trimester in pregnancy. In third trimester reliability of any single parameter has limitations. Methods: This was a hospital based comparative cross-sectional study done in the Department of Obstetrics and Gynaecology, S.M.S. Medical College and attached hospitals, Jaipur, Rajasthan. The period of study was from June 2018 to October 2019. Results: The mean TCD at 15 weeks and 40 weeks was 15.00 ± 0.00mm and 53.33±1.155mm respectively. The mean BPD at 16 weeks and 40 weeks was 33.50±0.70mm and 93±1.528mm respectively. The mean HC at 15 weeks and 40 weeks was 111.00±1,41mm and 340±2.00mm respectively. The mean FL at 15 weeks and 40 weeks was 18.50±0.70mm and 77.67±1.528mm respectively. The mean AC at 15 weeks and 40 weeks was 99.00±1.41mm and 365.33±8.32mm respectively. Conclusion:  We conclude that foetal transcerebellar diameter can thus be used as an alternative foetal parameter to assess gestational age and can be used in cases of wrong dates or when other routine parameters are not conclusive or did not accurately predict gestational age for e.g. in cases of hydrocephalus, brachycephaly, dolicocephaly, intrauterine growth restriction, achondroplasia or short limb dwarfism.

Placental Thickness

Introduction: Placenta grows in size with the advancement of gestational age (GA) and plays an important role for delivery of nutrients from mother to fetus. Ultrasonography (USG) is implicated for the estimation of GA by using fetal growth parameters like Femur Length (FL), Bi-parietal Diameter (BPD), Head Circumference (HC), and Abdominal Circumference (AC). This study intends to observe the correlation between Placental Thickness (PT) and GA. Methods: It was an observational, cross-sectional, and analytical study conducted over a period of six months from November 2017 to April 2018. Fetal growth parameters i.e. FL, BPD, HC, and AC were measured to estimate GA. PT was also measured at the same time. Results: There was a positive correlation between PT and GA (r = 0.89, n=249, p < 0.001). Pearson correlation coefficient between the two variables at second and third trimesters were 0.81 and 0.49 respectively. Fisher r-to-z transformation was used to analyze the difference between those two coefficients and was found to be statistically significant (z = 4.6, p < 0.001). This indicates that there was a significant overall relationship between PT and GA. As GA increases, PT also increases. Conclusion: Our study observed a positive correlation between the PT and GA in second and third trimesters. Thickness of placenta can thus be used as a reliable parameter for the estimation of GA during the second and third trimesters, and can be used as a supplementary USG parameter along with FL, BPD, HC and AC.

Background: Gestational age of the newborn can be assessed by various methods. Aim of this study was to estimate the gestational age using foot length of the neonate and to find the correlation between foot length and gestational age assessed by last menstrual period and first trimester ultrasound.Methods: It was a hospital based prospective cross-sectional study done at Newborn ward, Department of Pediatrics, MGM Govt. hospital attached to KAP Viswanatham Govt. Medical College, Tiruchirappalli, involving 170 newborns with 10 babies in each gestational age ranging from 26 weeks to 42 weeks. Gestational age of all babies were assessed using last menstrual period, first trimester ultrasound and New Ballard Score soon after birth. Right foot length of each baby was measured from heel to tip of great toe or second toe whichever was longer, within 12-24 hours of life. Measurements were taken using a plastic ruler, measuring tape and by measuring the length of foot print ink impression.  Gestational age obtained by various methods were assessed for their correlation with foot length.Results: Positive correlation was obtained between foot length and gestational age determined by LMP (r= 0.965) and ultrasound (r= 0.964). Hence foot length could be reliably used to predict gestational age of newborn.Conclusions: Foot length measurements can be used as a non-invasive alternative method to assess gestational age of newborn, especially by community health workers and thus can facilitate the early identification of preterm babies.

Background: Different scoring systems based on neurological and physical examination are used in the neonatal units for assessment of gestational age. Assessment of gestational age is very much helpful in labelling the newborn to be preterm, term or post – term and to assess the further outcome of the newborn infants. Present study was performed to test the accuracy and reliability of the Ballard scoring system as compared to Dubowitz scoring system on 250 newborn infants and their correlation with the gestational age as calculated from first day of mother’s last menstrual period. In infants of 38 weeks onwards correlation of gestational age was done with the extension of plantar creases over sole.Methods: Infants studied were selected from infants born in Muzaffarnagar Medical College and Hospital Muzaffarnagar and those infants admitted to the neonatal intensive care unit. First of all methods of eliciting different criteria were experienced by examining several newborn infants and then Dubowitz and Ballard scoring system were performed separately and gestational age assessed. crease was measured, using metallic scale from base of great toe after stretching the sole.Results: Gestational ages estimated by Ballard scoring system and Dubowitz system strongly correlated with the gestational ages computed from the date of mother’s last menstrual period. The coefficient of correlation calculated between Ballard and Dubowitz scoring system showed perfect positive correlation on the regression line.  Association of gestational age with the length of sole crease was also very significant.Conclusions: The clinical test of maturation described by Ballard et al and which is evaluated in the present study, takes a balanced look at physical and neurological maturation and included those items found to be most useful regardless of the presence or absence of diseased state.
