Intrauterine Foetal Death: A Hospital Based Study

Introduction: Foetal death at any stage of pregnancy is not just a tragic event but also a more traumatic for the mental well-being of a mother. It is one of the most wrenching events in the field of obstetrics. Aims: The study was done to determine the probable risk factors of intrauterine foetal death and role of antenatal care in its prevention. Methods: The study was conducted in Obstetrics and Gynecology department at Nepalgunj Medical college from July 2018 to July 2020 .Inclusion criteria were intrauterine fetal death of >28 weeks of gestation and baby weighing 1000 grams or more . An exclusion criterion was molar pregnancy. Results: There were 115(3.52%) intrauterine fetal death during the study period, making it 35 per 1000 cases. In 17(14.78%) the cause of intrauterine fetal death was not known. The other common associated risk factors were prematurity in 14(12.17%) and hypertension in 13(11.30%). Similarly anemia and antepartum hemorrhage were seen in 13(11.30%) each. 11(9.56%) patients had oligohydramnios. Mal presentation was found in 8(6.95%) patients while polyhydromnios in 6(5.21%).The commonest age range in whom intrauterine fetal death was seen was 20-30 (73.90%). 28 (24.34%) patients were at preterm pregnancy ranging between 28-30 weeks whereas 17(14.78) intrauterine fetal death occured at 32-34 weeks. 77 foetuses were preterm and their birth weight was between 1 - 1.5 kg with the mean wt of 1175.73 gms. Conclusion: Intrauterine fetal death is still common inspite of the improving awareness in importance of regular antenatal care. In majority, the cause of intrauterine fetal death is still unknown. However, where the cause was known prematurity was the commonest.

Effect of Aspirin Dose on Preeclampsia Prevention and Fetal-maternal Complications: A Randomized Clinical Trial

Background: Preeclampsia (PE) is a disease characterized by abnormalities in the placenta and endothelial cells. The pathogenesis is not fully understood; however, aspirin prescription can be effective to treat the disease and prevent fetal developmental disorders. Methods: This study was performed as a clinical trial in Shahid Akbrabadi Hospital in Tehran city. Eighty patients participated in two groups (n = 40). The first group of patients received the dose of 80 mg, and the second group received the dose of 160 mg aspirin. Then, the fetal-maternal and treatment process complications were examined in the patients. Results: The results showed that the incidence of fetal-maternal complications, including intrauterine growth restriction (IUGR) and intrauterine fetal death (IUFD) was lower in patients treated with 160 mg aspirin than in the other group, but this difference was not statistically significant (P-value > 0.05). Aspirin complications such as bleeding were more in the second group than in the first one (P-value < 0.05). Conclusions: Although the increasing dose of aspirin reduces fetal-maternal complications in PE patients, the problems such as aspirin-induced bleeding should be considered.

Sigmoid volvulus in pregnancy: a case report

Introduction Sigmoid volvulus in pregnancy is a rare cause of intestinal obstruction with high maternal and fetal morbidity and mortality if not diagnosed and managed early. Case presentation A 29-year-old female (Chagga by tribe) presented with clinical features of intestinal obstruction 24 weeks into her second pregnancy. She had symptoms for one week. An emergency laparotomy was performed whereby gangrenous sigmoid volvulus was found; thus, it was resected and Hartmann’s colostomy was raised. Unfortunately, she experienced intrauterine fetal death post-operatively. She was discharged clinically stable. Conclusion Early diagnosis and management can prevent adverse effects such as bowel ischemia and preterm labor. Because classic clinical and radiological features may not be evident, high degree of suspicion is warranted.

The Pathological Mechanisms of Estrogen-Induced Cholestasis: Current Perspectives

Estrogens are steroid hormones with a wide range of biological activities. The excess of estrogens can lead to decreased bile flow, toxic bile acid (BA) accumulation, subsequently causing intrahepatic cholestasis. Estrogen-induced cholestasis (EIC) may have increased incidence during pregnancy, and within women taking oral contraception and postmenopausal hormone replacement therapy, and result in liver injury, preterm birth, meconium-stained amniotic fluid, and intrauterine fetal death in pregnant women. The main pathogenic mechanisms of EIC may include deregulation of BA synthetic or metabolic enzymes, and BA transporters. In addition, impaired cell membrane fluidity, inflammatory responses and change of hepatocyte tight junctions are also involved in the pathogenesis of EIC. In this article, we review the role of estrogens in intrahepatic cholestasis, and outlined the mechanisms of EIC, providing a greater understanding of this disease.

Outcome of Preterm Labour in SSMC Mitford Hospital, Dhaka.

Introduction: : Preterm birth as a consequence of preterm labour is the major clinical problem associated with perinatal mortality, serious neonatal morbidity and moderate to severe childhood disability and two-thirds of all perinatal deaths. Moreover, preterm labour comprises a large number of low birth weight babies. Global incidence of preterm labour is 5-10% of all births. The aim of this study was to determine the clinical profile and to find out pregnancy outcomes of preterm labour. Materials & Methods: This cross-sectional study was conducted in Sir Salimullah Medical College Mitford Hospital, Dhaka from January 2005 to December 2005. A total 103 gravid women who got admitted with established premature labour pain were included as study patients. Preterm labour associated with severe pre-eclampsia, eclampsia, antepartum haemorrhage and intrauterine fetal death were excluded. Data were collected in a pre-designed questionnaire and analyzed by SPSS software. Results: Incidence of preterm labour was found 6.3%. Among maternal morbidities, puerperal sepsis found to be highest (14.56%) followed by UTI (7.77%), PPH (6.80%), wound infection (5.83%) and retained placenta (3.88%). This study found perinatal mortality 32.0% and morbidity 49.5% of which RDS contributed highest (24.27%) followed by neonatal jaundice (11.65%), septicemia (8.73%), neonatal convulsion (2.91%) and umbilical sepsis (1.94%). Conclusion: Preterm labor followed by preterm birth significantly contributes to maternal morbidity and perinatal morbidity and mortality. Medicine Today 2021 Vol.33(2): 143-146

Complications of intravascular intrauterine transfusion for Rh alloimmunization

BACKGROUND: Intravascular intrauterine transfusion (IUT) is considered a safe procedure, but complications still occur, including fatalities. OBJECTIVE: Review the outcomes of Rh alloimmunization, including indications and possible complications. DESIGN: Retrospective cohort (medical record review). SETTING: Tertiary care center. PATIENTS AND METHODS: We retrieved the records for all mothers who had an IUT for Rh alloimmunization between January 2009 and August 2019. We collected data on complications, post-transfusion hemoglobin and antibody combinations. MAIN OUTCOME MEASURE: Complications of IUT. SAMPLE SIZE: 119 mothers with 154 fetuses (154 different pregnancies). RESULTS: The 154 fetuses had 560 intrauterine transfusions. The median pre-IUT hemoglobin was a median of 8.0 g/dL while the median post-IUT hemoglobin 16 g/dL. Immediate procedure-related complications included fetal bradycardia in 2.7%, significant bleeding from the cord puncture site (for more than 2 minutes in 0.9%), and contractions in 0.9%. Eight (5.2%) were delivered by cesarean delivery due to IUT-specific complications such as post-procedure fetal bradycardia. Intrauterine fetal death complicated 8.4% of the pregnancies (13 fetuses). Phototherapy was required in 76 (49.4%), postnatal blood transfusions in 17 (11%), and exchange transfusion in 11 (7.1%). Neonatal death occurred 8 (5.2%). Data were insufficient to assess associations of complications with antibody combinations. CONCLUSIONS: Intrauterine transfusion is an effective treatment with high survival rates (around 90% for cases of Rh alloimmunization). LIMITATIONS: Case series. CONFLICT OF INTEREST: None.

Maternal and neonatal outcomes in pregnancies complicated by eclampsia – analysis of cases from 2008–2018

Objective: Evaluation of perinatal results in a set of pregnancies complicated by eclampsia. Methods: Analysis of 67,304 births performed at the Department of Gynecology and Obstetrics, Masaryk University, Faculty of Medicine and University Hospital, Brno from 2008–2018. During the given period, eclampsia was dia gnosed in 16 mothers (0.2‰). The during the time of eclampsia (week of gestation, prepartum, intrapartum, postpartum) fetal and neonatal status (signs of intrauterine distress, pH of the umbilical artery, Apgar score, intrauterine fetal death, death in the early neonatal period) were evaluated. Symptoms and course of the eclamptic attack, maternal comorbidities, associated obstetric complications (placental abruption, surgical complications, blood loss, hysterectomy) and non-obstetric complications (coagulopathy, renal and hepatic impairment, neurological complications) were monitored. Results: Out of a total of 16 cases of eclampsia, 13 cases (81.3%) were confi rmed during pregnancy, one case (6.2%) during childbirth, and two cases (12.5%) within 24 hours after childbirth. The mean gestational week of eclampsia was 33 weeks and 3 days. The typical course of an eclamptic attack characterized by headache and visual disturbances followed by a rapid onset of convulsions was noted in fi ve cases (31%). Fetal hypoxia with a pH of the umbilical artery less than 7.10 occurred in four cases (25%). The dependence of the decrease in pH value on the time interval from the dia gnosis of eclampsia to the termination of pregnancy was demonstrated. The pH of the umbilical artery decreased on average by 0.054 every 30 minutes from the onset of the eclamptic attack until the end of pregnancy. There were 3 perinatal deaths in the group (19%). Intrauterine fetal death occurred in one case due to partial abruption of the placenta during an eclamptic attack; two newborns died in the early neonatal period. The cause of death was sepsis in one case and perforation of the intestine in necrotizing enterocolitis in the other. The death of the mother was not recorded in the fi le. The incidence of preeclampsia in subsequent pregnancies reached 18.8%. Non-obstetric and neurological complications (amaurosis, subarachnoid hemorrhage, amnesia) occurred in the group in three cases (18.8%), and renal failure occurred in two cases (12.5%). Conclusion: The incidence of eclampsia at the Department of Gynecology and Obstetrics, Masaryk University, Faculty of Medicine and University Hospital, Brno reached 0.2‰ and was stable for a long time. Associated serious maternal complications occurred in 37.5% of cases and neonatal complications in 31.3% of cases. Early dia gnosis of eclampsia and minimization of the time delay until the end of pregnancy is a prerequisite for reducing the risk of associated complications. An interdisciplinary approach is needed. Key words: eclampsia – convulsions – urgent conditions in obstetrics – perinatal outcomes – hypoxia

Obstetric Outcomes in the Surviving Fetus after Intrauterine Fetal Death in Bichorionic Twin Gestations

Twin pregnancies are high-risk gestations that increase the odds of obstetrical complications. They can also present specific and rare complications such as single intrauterine fetal death (IUFD). This complication has been extensively studied in monochorionic but not in bichorionic gestations. Today, the repercussions of IUFD may have on the surviving fetus, mother and bichorionic pregnancy are not known. Our objective was to study materno-obstetrical, fetal, and immediate delivery neonatal complications in bichorionic twin gestations with single IUFD compared to those with both fetuses alive. A retrospective and observational case-control study was performed in bichorionic biamniotic twin pregnancies, 22 complicated with single IUFD after 14 weeks (cases; IUFD group) and 51 with both fetuses alive (controls; non-IUFD group, from Obstetrics Service of La Paz Hospital (Madrid; Spain). The data were collected from obstetrical records. No significant differences were found in the rates of gestational diabetes, gestational hypertension, preeclampsia, neonatal complications, and prematurity between IUFD and non-IUFD groups. Statistical differences were found for the incidence of intrauterine growth restriction in the surviving fetus compared to first fetus of pregnancy with both fetuses alive (22.7% versus 2.0%, respectively; p-value = 0.012). There were no differences compared to second fetus (11.8%; p-value = 0.23). There was a high C-section rate in both groups (IUFD = 63.6%, non-IUFD = 64.7%; p-value = 0.19). In conclusion, single IUFD in bichorionic biamniotic twin gestations is a rare complication that should be closely monitored. It is essential that these gestations be attended by a clinical multidisciplinary team.

Maternal B Cell-Intrinsic MyD88 Signaling Mediates LPS-Driven Intrauterine Fetal Death

Immunological networks balance tolerance towards paternal alloantigens during pregnancy with normal immune response to pathogens. Subclinical infections can impact this balance and lead to preterm birth or even intrauterine fetal death (IUFD). We recently showed that loss of maternal B cells renders murine fetuses susceptible to IUFD after LPS exposure. Since the signaling pathway involved in this B-cell mediated response remains unclear, we aimed to understand the participation of MyD88 in this response using B-cell-specific MyD88-deficient (BMyD88-/-) mice. B cells isolated from wild-type (WT), BMyD88-/-, CD19-/- and MyD88-/- dams on gestational day (gd) 10 responded differently to LPS concerning cytokine secretion. In vivo LPS challenge on gd 10 provoked IUFD in CD19-/- mothers with functional MyD88, while fetuses from BMyD88-/- and MyD88-/- mice were protected. These outcomes were associated with altered cytokine levels in the maternal serum and changes in CD4+ T-cell responses. Overall, the loss of MyD88 signaling in maternal B cells prevents the activation of cytokine release that leads to IUFD. Thus, while MyD88 signaling in maternal B cells protects the mother from infection, it ultimately kills the fetus. Understanding the cellular mechanisms underlying infection-driven pregnancy complications is the first step to designing powerful therapeutic strategies in the future.
