RESUMO
OBJECTIVE: To describe the characteristics and outcomes of prelabour uterine ruptures. DESIGN: Descriptive study based on population data from the Medical Birth Registry of Norway, the Patient Administration System and medical records. SAMPLE: Maternities with uterine rupture before start of labour in Norway during the period 1967-2008 (8 complete ruptures among 2 334 712 women with unscarred uteri, and 22 complete and 45 partial ruptures among 121 085 women with scarred uteri). METHOD: We measured the rate of perinatal deaths and peripartum hysterectomy following ruptures. In addition, we studied the characteristics of ruptures. RESULTS: The eight complete ruptures in women with unscarred uteri were associated with trauma from traffic accidents (n = 3; 37.5%), previous curettage (n = 3; 37.5%) and congenital uterine malformations (n = 2; 25%), resulting in seven perinatal deaths and two hysterectomies. The 22 complete ruptures in scarred uteri were mostly outside the lower uterine segment (n = 17; 72.7%). Abnormally invasive placenta (AIP) and previous rupture were present in four (18.2%) and three women (13.6%), respectively. They resulted in nine perinatal deaths (39.1%) and two hysterectomies (9.1%). The 45 partial ruptures involved mostly scars in the lower uterine segment (n = 39; 86.7%). None of them resulted in perinatal death or hysterectomy. Perinatal deaths have decreased dramatically in recent years, despite increasing prelabour rupture rates. CONCLUSION: Although complete uterine ruptures before labour start were rare, they often resulted in catastrophic outcomes, such as perinatal death. Scars outside the lower segment were associated with a higher percentage of catastrophic prelabour ruptures compared with scars in the lower segment (Video S1). TWEETABLE ABSTRACT: Complete prelabour uterine ruptures were rare, but resulted in high perinatal deaths, especially if they were in scars outside the lower segment.

INTRODUCTION: The objective was to evaluate the association between fetal sex and adverse pregnancy outcome, while correcting for fetal growth and gestational age at delivery. MATERIAL AND METHODS: Data from the Netherlands Perinatal Registry (1999-2010) were used. The study population comprised all white European women with a singleton delivery between 25+0 and 42+6 weeks of gestation. Fetuses with structural or chromosomal abnormalities were excluded. Outcomes were antepartum death, intrapartum/neonatal death (from onset of labor until 28 days after birth), perinatal death (antepartum death or intrapartum/neonatal death), a composite of neonatal morbidity (including infant respiratory distress syndrome, sepsis, necrotizing enterocolitis, meconium aspiration, persistent pulmonary hypertension of the newborn, periventricular leukomalacia, Apgar score <7 at 5 minutes, and intracranial hemorrhage) and a composite adverse neonatal outcome (perinatal death or neonatal morbidity). Outcomes were expressed stratified by birthweight percentile (

PURPOSE: To examine whether the presence of peritoneal adhesions at the second cesarean delivery (CD), attributable to the first CD, are associated with maternal intra-operative organ injury and adverse neonatal outcomes. METHODS: A retrospective cohort study was conducted, comparing severe maternal intra-operative organ injury and adverse neonatal outcomes, between women with and without peritoneal adhesions. All women with two CDs during the follow-up period were included. Women with adhesions diagnosed during the first CD, history of other abdominal or pelvic surgery, pelvic infection or pelvic inflammatory disease, endometriosis, uterine Mullerian anomalies and newborns with known chromosomal or structural abnormalities were excluded, resulting in 7925 women. Intra-operative peritoneal organ injury was defined as a composite of bladder injury, ureteral injury, small bowel injury or hysterectomy. The examined adverse neonatal outcomes were low 1 and 5 min Apgar scores, intrapartum death (IPD) and postpartum death (PPD). Multivariate logistic regression was performed. RESULTS: Peritoneal adhesions at the second CD, attributable to the first CD were diagnosed in 32.6% of patients (n = 2581). The presence of peritoneal adhesions was not found to be independently associated with intra-operative organ injury nor with 5 min Apgar scores, IPD and PPD. Second CDs complicated with adhesions were found to be associated with low (< 7) 1 min Apgar scores (adjusted OR 1.38, CI 1.20-1.58, p < 0.001). CONCLUSION: Adhesions attributable to a previous CD do not seem to increase the risk for intra-operative organ injury and adverse neonatal outcomes. These findings may assist in reassuring patients who are facing a second CD.

BACKGROUND: Exposure to adverse perinatal events can impact on the way healthcare professionals (HCPs) provide patient care. The aim of this study was to document the experiences of HCPs following exposure to intrapartum death (IPD), to identify opinions surrounding education and suitable support strategies, and to ascertain if involvement with an IPD had any impact on clinical practice. METHODS: A questionnaire study, with open and closed questions, was developed and set in a tertiary maternity hospital. Consultant obstetricians, trainee obstetricians and midwives were invited to participate. Respondents were questioned about the impact that an intrapartum death had on them, the support they received in the immediate aftermath and their opinions regarding ongoing education and training in the areas of intrapartum death and self-care. RESULTS: Eighty percent of HCPs in our study had a direct involvement with an IPD. Most (82%) HCPs received no training in dealing with IPD while 94% had no education on self-care strategies. Despite it being desired by most (80%), debriefing was offered to just 11% of HCPs who were involved in an IPD. Three main qualitative themes emerged from the data; the personal impact of IPDs on HCPs, implications for professional practice and future patient care, and the importance on non-judgemental support. CONCLUSION: Maternity hospitals need to improve their support structures for HCPs following an IPD. It is hoped that this study will inform future educational practice and identify potential support strategies.

Left ventricular noncompaction (LVNC), involving mainly the right ventricle, is a rare form of congenital heart disorder characterized by a developmental arrest in myocardial compaction, resulting in a spongy appearance of the myocardium, mainly of the right ventricle, rarely detected in fetuses. We report the case of a female fetus with a gestational age of 41+4 weeks who came to our attention for intrapartum sudden unexpected death, resulting in stillbirth. The ventricular walls, particularly the right ventricular wall, appeared thick, hypertrabeculated and spongy, leading to the diagnosis of LVNC involving mainly the right ventricle. The atrioventricular node and His bundle presented areas of fetal dispersion and resorptive degeneration; islands of conduction tissue were detected in the central fibrous body. Arcuate nucleus of the brainstem showed bilateral severe hypoplasia. The right bundle branch was hypoplastic. The final cause of death was an electrical conduction disfunction in an LVNC involving mainly the right ventricle. To the best of our knowledge, the herein described case is the first reported observation of sudden intrapartum death from LVNC involving mainly the right ventricle well documented post-mortem with cardiac conduction and brainstem studies. Our findings confirm the need of an accurate post-mortem examination including the study of the cardiac conduction system on serial section in every case of sudden unexpected fetal death, although there are no universally recognized guidelines.

OBJECTIVE: To identify risk factors for antepartum fetal death (APD) in term pregnancies while considering maternal, pregnancy and fetal characteristics. MATERIALS AND METHODS: Our study took place between the years 1988-2013. A total of 272,527 singleton births at term were recorded during this time period, including 524 cases of APD (0.2%). Cases of known chromosomal or other fetal abnormalities and cases with poor prenatal care were excluded. In order to identify independent risk factors contributing to antepartum fetal death in term we conducted a multivariate analysis using logistic regression. RESULTS: The main risk factors found to be significantly associated with APD in term were suspected intrauterine growth restriction (OR = 2.70, p < .001), diabetes (OR = 1.37, p = .05), hypertensive disorders (OR = 1.59, p = .01), advanced maternal age (OR = 1.03, p < .001) and grand-multiparity (OR = 1.79, p < .001). Advanced gestational age was not significantly associated with APD (38.95 vs. 39.44, p < .001). CONCLUSIONS: Most of the risk factors for antepartum fetal death in term pregnancies found in this study coincide with known risk factors for APD as described in previous studies. We believe that in the presence of these risk factors, closer surveillance and careful medical management of the pregnancy are required, in order to reduce the incidence of APD, including induction of labor at advanced gestational age.

OBJECTIVE: The present study is intended to investigate the causes of stillbirth and its relationship with maternal conditions using the International Classification of Diseases-Perinatal Mortality (ICD-PM) system. MATERIAL AND METHODS: All early and late fetal deaths between 2015 and 2020 were analyzed. Time of death, fetal causes, and the maternal conditions involved were identified using the ICD-PM classification system. RESULTS: During the study period, out of 74,102 births a total of 475 stillbirths were recorded (6.4 per 1000 births), of which 83.6% of the cases were antepartum and 11.8% were intrapartum fetal deaths, and the time of death could not be determined in 4.6% of the cases. Fetal developmental disorder was the most common cause of antepartum fetal death (24.2%). Intrapartum deaths were mostly due to extremely low birth weight (44.6%). The most common maternal conditions involved were complications of placenta, cord, and membranes (19.8%). CONCLUSION: The applicability of the ICD-PM classification system for stillbirths is easy. It was observed that fetal deaths mostly occurred in the antepartum period and the cause of death could not be identified in over half of these antepartum fetal deaths. In over half of the stillbirths, there is at least one maternal condition involved. The most common maternal conditions involved are complications of placenta, cord, and membranes. The most common maternal medical problem is hypertensive diseases of pregnancy.

OBJECTIVE: To identify risk factors in first pregnancy for perinatal mortality in the subsequent pregnancy. METHODS: A retrospective population-based nested case-control study was conducted, including all women with two first singleton consecutive deliveries. Women with perinatal mortality in their first pregnancy were excluded, and cases with perinatal mortality in the second pregnancy were compared with controls who delivered a live birth. Characteristics and complications of the first pregnancy were compared between the groups using multivariable logistic models. RESULTS: A total of 43 043 women were included in the study, 385 (0.9%) were cases. Cases, as compared with controls (live births), were younger (22.62 ± 4.0 vs 23.22 ± 4.0 years), with shorter inter-pregnancy interval (1.38 ± 1.55 vs 1.56 ± 1.53 years), and were more likely to have the following complications in their first pregnancy: severe pre-eclampsia (3.4% vs 1.7%), small for gestational age (12.5% vs 8.0%), preterm delivery (17.7% vs 7.8%), and congenital or chromosomal malformations (9.6% vs 5.9%). In multivariable analysis the risk for perinatal mortality was greater with each additional complication (adjused odds ratio [aOR] 1.64, 95% confidence interval [CI] 1.30-2.07, P < 0.001; aOR 2.55, 95% CI 1.61-4.04, P < 0.001; aOR 7.88, 95% CI 3.81-16.29, P < 0.001 for one, two, and three or more complications, compared with no complications, respectively). CONCLUSION: Complications in first pregnancy ending with live birth are associated with increased risk for perinatal mortality in a subsequent pregnancy.

From a forensic pathologist's perspective, there are several aspects of the perinatal postmortem that are particularly important. If a fetus is found abandoned, the pathologist needs to ascertain the fetal age, the appropriateness of growth, if the baby was born alive or dead, and the possible causes of death. In cases of litigation for perinatal deaths occurring in hospitals, access to the obstetric and neonatal notes (if the baby is born alive and dies a few hours or days later) is fundamental to reach a correct interpretation and conclusion. The most important points to consider in cases of intrapartum death are the roles of asphyxia and trauma in the causation of the baby's death. Timing of the fetal death in relation to delivery may also be an important point in these cases. Finally, intrapartum lesions should always be considered in the differential diagnosis of possible child abuse in babies aged two months or less.
