At First, as the training group, we performed US examinations on 186 healthy singleton fetuses within 3 days of delivery. Three input variables were used to construct the ANN model: abdominal circumference (AC), ab-dominal diameter (AD), biparietal diameter (BPD). Then, a total of 121 twin fetuses were assessed sub-sequently as the validation group. In validation group, the mean absolute error and the mean absolute per-cent error between estimated fetal weight and actual fetal weight was 261.77 g and 7.81%, respectively. Results show that, twin estimation of birth weight by ultrasound correlates fairly well with the actual weights of twin fetuses.展开更多

However, the growth of fetal membranes may be collective or singly. There is little data from sonographic view of assessment on the exact progression at different stages of gestation. More so, the realistic evidences from radiographic assessment of the compartmentalization of chorion membrane in the developing monochorionic and dichorionic twins are not sufficiently available, hence, the call to ascertain the exact progression of the chorion membrane through ultrasound scanning in gestational subjects. Aim: This present study examined the structural progression of embryonic growth pattern of chorionic membrane in monochorionic and dichorionic twins. Materials and Methods: The study utilized transabdominal ultrasound to periodically assess the progression of chorion membrane and advancement in compartmentalization of monochorionic and dichorionic twins as pregnancy proceeds. Results: The monochorionic membrane showed an enclosure that progresses to be more distinct and thickened around the two embryos with a unique T-shaped point of insertion in latter development. The partitioning of dichorionic membrane progresses to be less thickened and with a distinct lambda (λ) sign which is a wedge-shaped protrusion into the inter-twin space. Conclusion: Assessment showed that the growth pattern of chorion membrane varied with different parameters observed as early as in the first trimester. Hence during early gestational stage, a twin can be said to be monochorionic or dichorionic with key anatomical landmarks monitored. The growth progression could be used to project abnormality and on time treatment would be offered to improve perinatal outcome.展开更多

A 34-year-old pregnant woman with normal thyroid function was referred to our Department of Obstetrics and Gynecology at Microcitemico Pediatric Hospital, Cagliari, for suspected fetal goiter at 32 gestational weeks. The case was monitored regularly by ultrasound and treated successfully with intra-amniotic levothyroxine (L-T4) administration. Fetal goiter was observed to decrease after this treatment and the thyroid ultrasound findings were also normal both at birth and in subsequent follow-ups. Our case report confirms the feasibility of conservative treatment with L-T4, which can effectively prevent complications related to fetal goiter.展开更多

Despite the progress in obstetrical and pediatric care that has occurred in recent years, twin delivery is still associated with high maternal morbidity and perinatal mortality. Few recent studies have focused on the complications and risk factors associated with complications of twin birth in our environment. The objective of our study was to identify the complications of twin birth and the factors associated with them. Methodology: We carried out a cross-sectional analytical study. Data collection was prospective, over a period of 4 months (January 1, 2022 to April 30, 2022), at the maternity units of the Gyneco-Obstetric and Pediatric Hospital of Yaoundé and the Central Hospital of Yaoundé. The study population included all pregnant women who gave birth to twins during our study period at these hospitals. Data analysis was done using the SPSS software (Statistical Package for the Social Sciences) version 23.0. The Chi-square test was used to compare proportions and the student’s t test to compare means. A p-value of less than 0.05 was considered statistically significant. Results: In total, we recorded 37 complicated twin deliveries out of a total of 66 twin deliveries. This corresponded to a complication rate of 56%. Maternal complications occurred in 11.38% of cases, the majority being soft tissue lesions (4.54%), and postpartum hemorrhage (4.54%). Perinatal complications at the time of delivery were dominated by early neonatal infections (12.12%), non-reassuring fetal condition (10.6%) and intrauterine fetal death (6.06%). Factors associated with complications of twin births after univariate analysis were: maternal age ≤ 30 years (OR = 8.15;CI = 9.78 - 71.06;P = 0.03), being a student, (OR = 5.09;CI = 3.65 - 7.10;P = 0.00), primary level of education (OR = 1.48;CI = 3.30 - 6.63;P = 0.00), having less than four prenatal contacts (OR = 5.76;CI = 12.2 - 27, 24;P = 0.02), lack of ultrasound assessments (OR = 2.65;CI = 1.08 - 4.65, P = 0.04), diagnosis of twinning at labor (P = 0.03), admission for preeclampsia and eclampsia (OR = 2.01;CI = 1.24 - 5.9;P = 0.04), qualification of birth attendant as midwife (OR = 2.33;CI = 6, 38 - 8.50;P = 0.00), delivery time greater than 15 minutes for the second twin (OR = 2.45;CI = 1.14 - 5.26;P = 0.019). Conclusion: twin birth remains associated with high maternal and neonatal morbidity in our environment. The rate of maternal-fetal complications is 56% in our series. Post-partum hemorrhage, soft tissue injury and early neonatal infections are the main complications. These are closely linked to a number of factors whose control would improve the prognosis of twin birth.展开更多
