Abstract:

Little is known about longitudinal changes of the first twin presentation in twin gestations. This is a retrospective cohort study including 411 women who were admitted consecutively and delivered live-born twins at 36 weeks of gestation or more. Longitudinal assessment of the first twin presentation was conducted during gestation and at birth in all cases. Gestational age at antenatal assessment was divided into two intervals: early-third trimester (28–31 weeks) and mid-third trimester (32–35 weeks). Fetal presentation was categorized as vertex or non-vertex. We analyzed change of fetal prese

Abstract:

AbstractIn order to evaluate the influence of birth order and fetal presentation on antenatal growth of twins we conducted a comparison of prospective measurements of five fetal biometric indices in 50 vertex-vertex and 47 vertex-breech twins. We compared (a) twin A to twin B in both groups; (b) the second and (c) the first twins of both groups. Both groups had similar maternal and neonatal characteristics. The growth curves of the twins were also very similar except for three significant (p<0.05) deviations: (a) Twin A of the vertex-vertex group, had larger femur length (FL) at 18-19 weeks

AbstractIn vaginally delivered births (including a few cases where the mothers were under epidural anesthesia), differences between first and second born twins were compared according to presentation at delivery. Of twins with vertex/vertex presentation in 15 primipara cases and in 14 multipara cases, pO2 levels for the second born were significantly lower (both being p < 0.05) than for the first born. Of twins vertex/non-vertex presentation, the second born in 9 primipara cases showed significantly lower pH, pO2 and HCO3 levels (p<0.05). Also for multipara twins, the second born had sig

Doppler examination of the umbilical artery and the fetal middle cerebral artery is evaluated predominantly in pregnancies with fetuses in cephalic presentation and never has been elucidated in breech presentation. Evidence on the accuracy of fetal weight estimation in dependence of the fetal presentation is controversial. Nevertheless, clinical decisions including recommendations for a cesarean section or labor induction based on these examinations are applied to pregnancies with fetuses in breech presentation.

A Multinomial Processing Tree (MPT) is a directed tree with a probability associated with each arc and partitioned terminal vertices. We consider an additional parameter for each arc, a measure such as time. Each vertex represents a process. An arc descending from a vertex represents selection of a process outcome. A source vertex represents processing beginning with stimulus presentation and a terminal vertex represents a response. An experimental factor selectively influences a vertex if changing the factor level changes parameter values on arcs descending from that vertex and no others. Ear

A directed graph is constructed for each such presentation, where vertices correspond to generators and edges represent the relations. In previous research, Cihan identified 35 families of digraphs that satisfy |V(Γ)|=|A(Γ)|-1, of which 11 of them do not contain leaves. This paper demonstrates that, with two exc

Abstract:

Background: Multiple pregnancy constitutes an important portion of high risk pregnancies and is a matter of grave concern to obstetricians and paediatricians owing to maternal and perinatal morbidity and mortality associated to it. Objective of present study was to evaluate maternal and perinatal outcome of twin pregnancy.Methods: This observational study included 50 women with twin pregnancy with gestational age of 26 weeks or more. Maternal and perinatal outcomes were studied.Results: The incidence of twin pregnancy was 2.8 % with maximum incidence in age group of 20 -29 years and in multigr

Abstract:

Background: Multifetal pregnancy constitutes a significant portion of high-risk pregnancies. This is due to the increasing obstetric and perinatal morbidity and mortality rates associated with it. Maternal and perinatal outcome of twin pregnancies has been evaluated in this study.Methods: Total 30 patients with twin pregnancy and having gestational age more than 28 weeks were included in this observational study.Results: Incidence of twins in the study was found to be 2%. Twin pregnancies were more common in multiparous women aged between 20 and 30 years. Most common foetal presentation was ve

Abstract:

Aim. Breech presentation complicates 3-4% of all term deliveries. This trial aimed to study the effect of combining spontaneous cephalic version (SCV) techniques with acoustic stimulation on the position of breech fetuses and their subsequent impact on maternal and neonatal outcomes. Materials and Methods. A randomized controlled trial was conducted involving 60 pregnant women at 32-34 weeks of gestation, all expecting a singleton fetus in complete breech presentation. They were assigned to two equal groups: Group (A) consisted of intervention participants who performed SCV techniques in conju

Abstract:

Background: Any presentation apart from the vertex is called a malpresentation. This includes brow, face, breech, shoulder and compound presentations. Malpresentation typically cause in increased caesarean sections, which has adverse outcomes for both mother and baby. Early analysis and management can save the obstetricians from complications. Objective: To recognize the causative factors and effect of malpresentation on maternal outcome amongst pregnant women delivering in tertiary care centers Methods: This became a retrospective observe carried out in the Department of Obstetrics and Gynaec

Abstract:

Objective: To examine the effect of twin-to-twin delivery time (TTDT) on neonatal outcome. Methods: We evaluated twin deliveries >34 weeks of gestation. Twin pregnancies with both twins delivered by cesarean section and pregnancies with antenatal complications were excluded. We analyzed TTDT and neonatal outcomes of the second twin (umbilical arterial pH value (pHart), Apgar scores at 1, 5 and 10 minutes, need for intensive care). The study population was divided into two homogenous groups based on the mode of delivery: (A) vertex presentation and vaginal delivery of both twins, (B) vertex

Abstract:

We consider Shimura varieties for orthogonal or spin groups acting on hermitian symmetric domains of type IV. We give regular $p$ -adic integral models for these varieties over odd primes $p$ at which the level subgroup is the connected stabilizer of a vertex lattice in the orthogonal space. Our construction is obtained by combining results of Kisin and the first author with an explicit presentation and resolution of a corresponding local model.

Abstract:

Background: Breech presentation is the commonest of all mal presentations. Vaginal delivery of breech presentation at term is associated with a much higher perinatal mortality and morbidity than that of vertex presentation.Methods: This prospective study was carried out in the department of obstetrics and gynaecology, S. S. G. Hospital, Baroda for a period of six months from 1st May 2019 to 31st October 2019. Out of a total number of 4476 deliveries, 159 were breech pregnancy.
