Background: White matter damage (WMD) is a prime risk factor for cerebral palsy, in part occurring unexplained. Though primarily a problem of preterm infants, there is growing evidence that in large newborns cephalopelvic disproportion and prolonged labor are involved. Objective: To explore both incidence of and morphometric risk factors for WMD in term-born infants. Study Design: We related growth variables and risk factors of term-born infants to WMD (61/4,725) using odds ratios of z -score bands...

Background: Cleidocranial dysplasia is a type of skeletal dysplasia, which is primarily characterized by delayed ossification of skeletal structures. It causes facial and oral abnormalities, resulting in difficult airway management and neuraxial anesthesia. Case presentation: The patient was a 24-year-old primipara (height 138 cm, weight 42 kg) with a hypoplastic right clavicle, patent fontanelles, dental malalignment, and a high palate. She was diagnosed with cleidocranial dysplasia at birth, although gene examination has not been performed...

BACKGROUND: Decision delivery interval (DDI) is the time line between a decision to conduct an emergency caesarean section and actual delivery of the baby. Prolong DDI constitute a third phase delay in provision of emergency obstetric care. Intervention designed to minimize DDI are vital, in attempt to prevent maternal morbidity and neonatal morbidity and mortality. The feasibility and practicability of the recommended DDI in recent studies have been questioned especially in limited resource setting and therefore the objective of our study was to determine the DDI and its associated fetalmaternal outcomes at a tertiary referral hospital in Tanzania...

Purpose: First, to describe a new method of assessing cephalopelvic disproportion by measuring the retropubic tissue thickness (RTT), and second, to determine whether RTT was associated with an eventual delivery by cesarean section. Methods: Three-dimensional transperineal ultrasound scans were performed on 129 laboring nulliparous women to obtain 3-dimensional volume datasets for assessing RTT. RTT was measured off-line by three operators (A, B, and C) as the shortest distance between the capsule of the pubic symphysis and the outer border of the fetal skull...

BACKGROUND: There is an alarming rise in caesarean section leading to increased adverse outcomes for both the mother and fetus when compared with vaginal delivery. Within this increasing caesarean section rate, there is a concerning increase in the rate of second stage caesarean section. This study highlight the feto-maternal outcome of caesarean section in second stage of labour. METHODS: This was a retrospective cohort review of all women with a singleton, cephalic fetus at term delivered by caesarean section in the second stage of labor between April 1, 2013 and March 30, 2017 at Patan Academy of Health Sciences...

OBJECTIVE: The most commonly used approved indications for mifepristone in obstetrics include: termination of early pregnancy, cervical dilatation prior to abortion, labour induction in case of fetal death in utero. Fewer studies have been conducted on the effect of mifepristone on cervical ripening and induction of labour in term pregnancy with a live fetus. The aim of our study was to evaluate efficacy and safety of mifepristone use for cervical ripening and induction of labour versus expectant management in full-term pregnancy...

BACKGROUND: The incidence of neonatal ear deformities varies widely in the literature, and the incidence of those that correct spontaneously is largely unknown. To address these questions, the authors analyzed the auricles of 1500 newborns from the Pearl River Delta within the first 7 days of life and again at 30 days of age. METHODS: Using a combination of direct measurement and digital image measurement, the authors measured physiognomic ear length, physiognomic ear breadth, morphologic ear length, vertical distance between head and ear, and auriculocephalic angle of the newborns...

It has long been noted that the human female birth canal is well adapted to giving birth to large-brained neonates. However, several species of nonhuman primates give birth to large-headed neonates compared to the maternal birth canal. The presence of such large cephalopelvic proportions in nonhuman primates presents the question of whether dimorphism in the birth canals of these other species is related to obstetric demand, as such dimorphism is presumed to be in humans. In this study, the hypothesis that either the presence or magnitude of dimorphism in the birth canal is related to large cephalopelvic proportions among anthropoid primates is directly tested...

Birth mechanics in early hominins are often reconstructed based on cephalopelvic proportions, with little attention paid to neonatal shoulders. Here, we find that neonatal biacromial breadth can be estimated from adult clavicular length (R2 = 0.80) in primates. Using this relationship and clavicular length from adult Australopithecus afarensis, we estimate biacromial breadth in neonatal australopiths. Combined with neonatal head dimensions, we reconstruct birth in A. afarensis (A.L. 288-1 or Lucy) and find that the most likely mechanism of birth in this early hominin was a semi-rotational oblique birth in which the head engaged and passed through the inlet transversely, but then rotated so that the head and shoulders remained perpendicular and progressed through the midplane and outlet oblique to the main axis of the female pelvis...

Pelvic sexual dimorphism in primates is typically seen as the result of female-specific adaptations to obstetric constraints, which arise from the tight fit between the neonate head and the maternal pelvis. However, it remains debated to which extent pelvic dimorphism is a correlate of obstetric constraints, of body size dimorphism, and/or of other factors. Also, little is known on how pelvic dimorphism develops. Here we use methods of biomedical imaging and geometric morphometrics to address these questions in two hylobatid species, Hylobates lar and Symphalangus syndactylus...

BACKGROUND: Women's self-reports of whether they had a cesarean delivery are nearly 100% accurate, but there is little extant research on how accurately women self-report reasons for cesarean delivery when asked to recall this information in the postpartum period. OBJECTIVE: We compared women's self-reported reasons for cesarean with their hospital discharge records and examined correlates of variability in agreement between sources. METHODS: Data are from the First Baby Study, a cohort of 3,006 women who gave birth to their first baby between 2009 and 2011...

BACKGROUND: Misdiagnosis may be a significant and under-recognized quality of care problem. In birthing facilities located in anurban Philippine setting, we investigated the diagnostic accuracy for three obstetric conditions: cephalopelvic disproportion (CPD), post-partum hemorrhage (PPH), and pre-eclampsia. DESIGN: Identical simulated cases were used to measure diagnostic accuracy for every provider (n=103). We linked misdiagnosis - identified by the simulated cases - to obstetrical complications of the patients at the participating facilities...

COMPARATIVE STUDY

Cephalopelvic disproportion is common among Africans and is a major cause of maternal and perinatal mortality and morbidity. As the dimensions of the pelvis may vary between populations and according to stature and age, they need to be considered during childbirth and also in the planning and performance of pelvic and perineal procedures. The aim of this study was to assess the possible variations in the dimensions of the intact pelvic canal in South Africans and their implications. Eighty intact cadaver pelves, belonging to 40 white South Africans (20 males and 20 females) and 40 black South Africans (20 males and 20 females) were used for both metric and geometric morphometric analyses...
