Middle cerebral artery ,Rh isoimmunisation ,reproductive and urinary physiology ,Foetal anaemia ,Foetal placenta doppler - Abstract
Objective: To describe the level of knowledge regarding the diagnosis, treatment and prognosis of maternal isoimmunisation among Gynaecology and Obstetrics specialists, members of ABP (Asociación Bogotana de Perinatología). Materials and methods: Cross-sectional descriptive study. A questionnaire prepared by specialists in Maternal and Foetal Medicine (MFM) was administered between November 2012 and March 2013. Professionals practicing outside the national territory, those who had not practiced over the past ten years, and those who did not provide all the information required were excluded. The tool consisted of 18 questions organized in three domains: socio-demographic characteristics, information about clinical practice, and knowledge of the subject. A descriptive statistical analysis was used. Results: Of the 220 practitioners who were given the questionnaire, 127 (57.7%) completed the survey and were included in the analysis. The cutoff point for the indirect Coombs was correctly identified by 32% of the obstetricians and by 45% of the specialists in MFM. The role of middle cerebral artery velocimetry for the diagnosis of foetal anaemia was recognized by 43% and 62% of obstetricians and specialists in MFM, and 82% and 76%, respectively, would use it for the follow-up of foetuses with anaemia. Only 76% of obstetricians and 66% of MFM specialists recognized the indications for delivering the baby in cases of foetal anaemia, whereas 90% and 97%, respectively, identified the timing for cordocentesis and in utero transfusion. Finally, 37% of obstetricians and 48% of MFM specialists did not recognize the Queenan- Liley curve as an option in cases where there is no access to foetal Doppler. Conclusion: There is an important variability in the level of knowledge among obstetricians and MFM specialists regarding the diagnosis, treatment and follow-up of pregnant women with isoimmunisation. Additional studies are required to characterize the variability in clinical practice regarding the diagnosis and treatment of maternal isoimmunisation in Colombia.

- Abstract
Introduction: Systemic lupus erythematosus (SLE) predominantly affects women, especially during their reproductive years, leading to increased risks during pregnancy. Latina women develop SLE at a younger age, which increases their susceptibility to pregnancy complications such as pre-eclampsia, preterm birth and fetal growth restriction., Objective: The purpose of this study is to systematically review maternal and fetal outcomes in pregnant Latina women with SLE and to perform a meta-analysis to assess specific risks associated with the disease., Materials and Methods: A systematic review according to PRISMA guidelines was performed (PubMed and SciELO), including studies on SLE and pregnancy in Latin America through December 2022. Eligible studies included case reports, cohort studies and clinical trials in pregnant women with SLE. The meta-analysis focused on key outcomes, including pre-eclampsia and lupus nephritis, with relative risk (RR) calculations., Results: Forty-four studies with 2190 pregnancies were included. High rates of pre-eclampsia (11-52 %), preterm delivery (18.6-70.8 %), and fetal loss were reported. A decades-long analysis of pregnancy outcomes in SLE in Latin America shows increased research and improved care, with fetal loss rates decreasing from 35 % (1980-1999) to lower intrauterine (28 %) and neonatal (10 %) death rates in 2020-2023. Meta-analysis showed that lupus nephritis almost doubled the risk of pre-eclampsia (RR = 1.89, 95 % CI:1.40-2.55) compared to women without nephritis., Conclusion: Latina women with SLE are at increased risk for adverse pregnancy outcomes, particularly pre-eclampsia and preterm delivery. Lupus nephritis and disease activity are major risk factors, highlighting the need for tailored care and early intervention to improve maternal and fetal outcomes in this population., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 Elsevier B.V.

- Abstract
The ductus arteriosus aneurysm (DAA) is considered a rare anatomical alteration that consists of a dilation of this vascular structure. It has been reported that the DAA can resolve in the immediate postnatal stage and do not generate any consequences for the neonate. However, have been described some cases in which the DAA is complicated due to thromboembolic events, rupture of the lesion, respiratory symptoms, and even death. We present a case report of aneurysm of the ductus arteriosus diagnosed at 24 weeks of gestation with detailed imaging study. Also, we highlight the importance of the use of fundamental tools in the diagnosis: 3D ultrasound, multiplanar reconstruction, spatio-temporal image correlation (STIC), and omniview., (© 2024 Wiley Periodicals LLC.)

- Abstract
Objective: To train healthcare professionals involved in the care of Rh-D negative pregnant women, with the aim of standardizing the management of Rh isoimmunization prevention, timely antenatal diagnosis of Rh disease, fetal assessment, and treatment of fetuses with Rh disease, in order to prevent adverse perinatal outcomes., Materials and Methods: A group of 23 expert panelists participated in the development of the consensus through three rounds, answering a questionnaire consisting of 8 domains and 22 questions. A modified Delphi method was used until the consensus threshold among participants was reached, defined as 80% or greater agreement in responses. In the third round of the expert panel, a twenty-third question emerged, which was answered by one of the thematic leaders. The eight domains of antenatal management for Rh-D negative pregnant women were: 1) Rh-D determination, 2) initial prenatal care for Rh-D negative patients, 3) titration and periodicity of the indirect Coombs test, 4) sensitizing events, 5) administration of anti-D immunoglobulin (IgG), 6) Doppler velocimetry of the middle cerebral artery (MCA), 7) antenatal management of isoimmunized patients and anemic fetuses, and 8) timing for pregnancy termination based on different clinical scenarios. Based on these responses, and a review of international clinical practice guidelines, consensus statements were formulated, including recommendations, their justification, and adaptation to the local context., Results: The following recommendations were issued: It is suggested that Rh-D negative women of childbearing age attend a preconception consultation. It is recommended to determine maternal Rh-D status at the first contact with health services, either during the preconception consultation or at the first prenatal check-up. For Rh-D negative patients, it is recommended to determine the Rh-D status of the child's father during prenatal care as early as possible, preferably before the 28th week of gestation. For Rh-D negative primigravidas, where the father is Rh-D positive, it is suggested to: a) determine and quantify Rh-D antibodies (indirect Coombs test) during the first consultation and then quarterly, b) expand the obstetric history, with an emphasis on identifying sensitizing events, and c) provide parental counseling regarding potential risks, the need for additional tests, and the possibility of immunization during pregnancy. During prenatal care for Rh-D negative multiparous patients with previous Rh-D positive offspring, the initial approach should include: a) determining and titrating Rh-D antibodies (indirect Coombs test); b) expanding the obstetric history, focusing on sensitizing events; and c) providing parental counseling about potential risks and additional tests. After a sensitizing event, it is recommended to administer anti-D IgG within the first 72 hours at a dose of 1500 IU (300 μg). If not feasible, it can be administered up to 4 weeks after the event if it was not given initially. 7.1. For non-isoimmunized pregnant women (with a negative Coombs test and Rh-positive newborn), it is recommended to administer anti-D IgG between weeks 28 and 32, and within the first 72 hours postpartum if the newborn is Rh-positive. The dose is 300 μg IM or IV. 7.2. In the case of a cesarean section in an Rh-D negative patient with a Rh-D positive child, the consensus does not recommend doubling the dose of anti-D IgG. The dose remains the same as after a vaginal delivery: 300 μg IM or IV. 7.3. In a twin delivery involving an Rh-D negative patient with two or more Rh-D positive live-born infants, the consensus recommends not doubling the dose of anti-D IgG. The dose remains 300 μg IM or IV, the same as after a vaginal delivery. 7.4. For a non-isoimmunized Rh-D negative patient in the puerperium with immediate postpartum surgical tubal sterilization and an Rh-D positive neonate, anti-D IgG is recommended, assuming no prior sensitization, given the potential for reproductive decision changes or failure of the procedure. An Rh-D negative patient is considered isoimmunized if: a) the indirect Coombs test is positive at any titer, provided anti-D IgG was not received in the previous month, or b) there is a history of adverse perinatal outcomes associated with Rh disease in prior pregnancies, such as hydrops. 9.1. If Rh-D negative women are isoimmunized, it is necessary to determine the anti-D antibody titer, as this titer correlates with the severity of the disease and determines the need for fetal anemia studies with Doppler velocimetry of the MCA. 9.2. For isoimmunized Rh-D negative patients, it is recommended to follow up with monthly quantitative indirect Coombs tests until week 24, then bi-weekly, or until reaching a critical titer (≥ 1:16). 10.1. Doppler ultrasound of the MCA is suggested for Rh-D negative patients with a positive indirect Coombs test and titers ≥ 1:16. 10.2. In non-isoimmunized Rh-D negative patients, the consensus does not recommend MCA Doppler velocimetry. 10.3. Weekly MCA Doppler ultrasounds are recommended for isoimmunized patients with indirect Coombs titers ≥ 1:16. 10.4. The consensus suggests adopting a cut-off value of ≥ 1.5 multiples of the median (MoM) of the peak systolic velocity for gestational age on MCA Doppler, as this value best correlates with fetal anemia. The consensus suggests Cordocentesis when fetal anemia is suspected, and intrauterine fetal transfusion when cordocentesis shows severe fetal anemia. This procedure should be performed by trained personnel. It is recommended to prolong pregnancy until the fetus has achieved sufficient lung and tissue maturation to improve perinatal survival, according to the indirect Coombs test titer threshold., Conclusions: It is essential to address Rh-D negative pregnant women, isoimmunized women, and fetuses with Rh disease in an appropriate and standardized manner, according to the Colombian context, across all levels of prenatal care. The recommendations issued in this consensus are expected to improve clinical care, as well as enhance perinatal health and neonatal quality of life in cases of Rh disease.

- Abstract
Objectives: To identify factors associated with poor prognoses in newborns with a prenatal diagnosis of gastroschisis in eight hospitals in Bogota, Colombia, from 2011 to 2022., Methods: A multi-center retrospective case-control study was conducted on newborns with gastroschisis in eight hospitals in Bogota, Colombia. Poor prognosis was defined as the presence of sepsis, intestinal complications, or death., Results: The study included 101 patients. Preterm newborns under 32 weeks had a poor neonatal prognosis (OR 6.78 95 % CI 0.75-319). Oligohydramnios (OR 4.95 95 % CI 1.15-21.32) and staged closure with silo (OR 3.48; 95 % CI 1.10-10.96) were risk factors for neonatal death, and intra-abdominal bowel dilation of 20-25 mm was a factor for the development of intestinal complications (OR 3.22 95 % CI 1.26-8.23)., Conclusions: Intra-abdominal bowel dilation between 20 and 25 mm was associated with intestinal complications, while oligohydramnios was associated with the risk of perinatal death, requiring increased antenatal surveillance of fetal wellbeing. Management with primary reduction when technically feasible is recommended in these infants, considering that the use of silos was associated with higher mortality., (© 2024 the author(s), published by De Gruyter, Berlin/Boston.)

- Abstract
Objective: To establish nomograms for linear measurements of the frontal and occipital horns of the lateral ventricle and their relationship, in pregnant patients between 18 and 40 weeks of gestation and having attended 2 units of Maternal Fetal Medicine in Bogotá-Colombia., Methodology: A descriptive cross-sectional study with an analytical component was carried out on pregnant patients who utilized the ultrasound services at 2 Maternal-Fetal Medicine units in Bogotá, between 18 and 40 weeks of pregnancy who underwent measurement. From the anterior and posterior horns of the lateral ventricles, the fronto-occipital ratio was calculated at each gestational week, and nomograms were created for each of these variables., Results: Nine hundred and seventy-eight patients were included in the study. The distance of the frontal horns ranged between 6.9 and 51.6 mm with a mean of 19.1 ± 5.8 mm; that of the occipital horns had a measurement between 8.7 and 53 mm with a mean of 28, 1 ± 8.9 mm; on the other hand, the fronto-occipital ratio (FOR) yielded a mean of 0.365 ± 0.067 (0.136-0.616) without bearing any relation to gestational age. The trend of normal values for the studied population is displayed, plotted in percentile curves and nomograms for each gestational age., Conclusion: The measurement of the frontal and occipital horns, and the calculation of the fronto-occipital relationship is technically possible between 18 and 40 weeks, finding that the anterior and posterior horns have a positive linear relationship with gestational age. Contrarily, the FOR does not correlate with the gestational age, it was possible to establish a table of percentiles that allows determining the normal values for these measurements during pregnancy., (© 2023 Wiley Periodicals LLC.)

- Abstract
Objective: To describe the texture characteristics in several anatomical structures within fetal ultrasound images by applying an image segmentation technique through an application developed in MATLAB mathematical processing software., Methods: Prospective descriptive observational study with an analytical component. 2D fetal ultrasound images were acquired in patients admitted to the Maternal Fetal Medicine Unit of the Hospital de San José, Bogotá-Colombia. These images were loaded into the developed application to carry out the segmentation and characterization stages by means of 23 numerical texture descriptors. The data were analyzed with central tendency measures and through an embedding process and Euclidean distance., Results: Forty ultrasound images were included, characterizing 54 structures of the fetal placenta, skull, thorax, and abdomen. By embedding the descriptors, the differentiation of biologically known structures as distinct was achieved, as well as the non-differentiation of similar structures, evidenced using 2D and 3D graphs and numerical data with statistical significance., Conclusion: The texture characterization of the labeled structures in fetal ultrasound images through the numerical descriptors allows the accurate discrimination of these structures., (© 2023 Wiley Periodicals LLC.)

- Abstract
Introduction: The optimal approach and therapy method for the acardiac twin with a reverse arterial perfusion sequence has not yet been established. The aim of this study was to determine the clinical practice patterns among international fetal therapy units in their management of these cases., Methods: A survey was sent to fetal centers across the world via email between December 2020 and December 2021., Results: Responses were obtained from 77% contacted centers. The most frequent ultrasound variables used in the evaluation of twin reverse arterial perfusion sequence include echocardiographic assessment of the pump twin and umbilical artery Doppler waveforms in the acardiac and pump twins, in 90% and 80% of the centers, respectively. Most centers in Europe and Latin America propose an in utero intervention in all cases. Most centers in Europe and Latin America prefer interstitial laser ablation, whereas radiofrequency ablation (RFA) is preferred in North America. The earliest gestational age for an intervention is on mean 13 weeks in Europe, which is earlier than the other geographic areas (p = 0.001)., Conclusions: Most centers agreed that antenatal evaluation should include echocardiography along with the UA Doppler waveform measurements, and the most frequently used interventions were interstitial laser ablation or RFA at a median between 14 and 26 weeks., (© 2023 S.

- Abstract
Objective: To evaluate survival outcomes of fetuses with right sided congenital diaphragmatic hernia (CDH) treated in Latin American centres and to assess the utility of left lung area to predict neonatal survival., Methods: A retrospective cohort including isolated right sided CDH cases managed expectantly during pregnancy in six tertiary centers from five Latin American countries. The utility of the observed/expected lung-to-head ratio (O/E-LHR) in predicting neonatal survival was assessed, and the best cut-off to predict prognosis was automatically selected by decision tree analysis., Results: A total of 99 right sided CDH cases were recruited, 58 isolated fetuses were selected at a median gestational age of 26.2 weeks, showing an overall survival rate of 26.2%. A linear trend was observed between survival and the O/E-LHR, showing that at higher O/E-LHR, the greater probability of survival (r = 0.56, p < 0.001). O/E-LHR discriminates two groups with different survival outcomes: fetuses with an O/E-LHR ≥65% showed a significantly higher survival rate than those with an O/E-LHR <65% (81.8% vs. 15.6%, p < 0.01)., Conclusions: Overall survival rate in right sided CDH is lower in Latin American countries. The severity category of pulmonary hypoplasia should be classified according to lung area and the survival rate in such population., (© 2021 John Wiley & Sons Ltd.)

- Abstract
Background/objectives: Prenatal myelomeningocele (MMC) repair has been shown to improve neurological outcomes. It has been suggested that decreases in the hysterotomy diameter during surgery can improve perinatal outcomes without altering neurologic outcomes. The objective of this study is to describe and compare the main maternal and fetal outcomes of fetuses undergoing open surgery for MMC repair, through the different modifications (standard-classical, mini-hysterotomy, and microneurosurgery)., Data Source: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Ovid, SciELO, LILACS, PROSPERO., Results: From a total of 112 studies, seven case series were selected including 399 fetuses with open fetal surgery, five studies using the classical technique (n = 181), one with mini-hysterotomy (n = 176), and one with the microneurosurgery technique (n = 42). The mini-hysterotomy and microneurosurgery techniques presented a lower risk of preterm delivery (21.4% and 30%, respectively) compared to the classic technique (47.3%), premature rupture of membranes (78%, 62%, and 72.5 %, respectively), oligohydramnios (0% and 72.5%, respectively), dehiscence of hysterotomy, maintaining the same frequency of Chiari reversion (78%, 62%, and 72.5%, respectively), postnatal correction requirement (0%, 4.8%, and 5.8%, respectively), and lower frequency of requirement for a ventriculoperitoneal shunt placement (13.0%, 7.5%, and 29.1%, respectively)., Conclusion: The least invasive techniques (minihysterotomy-microneurosurgery) are possible and reproduceable, as they are associated with better maternal and perinatal outcomes., (© 2021 John Wiley & Sons Ltd.)

- Abstract
Objective: To assess clinical impact, psychological effects, and knowledge of pregnant women during the COVID-19 outbreak in seven cities in Colombia. Currently, there are uncertainty and concerns about the maternal and fetal consequences of SARS-CoV-2 infection during pregnancy., Methods: A cross-sectional web survey was carried out including pregnant women in seven cities in Colombia. Women were evaluated during the mitigation phase of the SARS-CoV-2 pandemic between April 13 and May 18, 2020. The questions evaluated demographic, knowledge, psychological symptoms, and attitudes data regarding the COVID-19 pandemic., Results: A total of 1021 patients were invited to participate, obtaining 946 valid surveys for analysis. The rate of psychological consequences of the pandemic was much larger than the number of patients clinically affected by the virus, with 50.4% of the entire cohort reporting symptoms of anxiety, 49.1% insomnia, and 25% reporting depressive symptoms. Poorly informed women were more likely to be younger, affiliated to the subsidized regime, and with lower levels of education., Conclusion: The knowledge of pregnant women about SARS-CoV-2 infection is far from reality and this seems to be associated with an indirect effect on the concern and psychological stress of pregnant women in Colombia., (© 2020 International Federation of Gynecology and Obstetrics.)

- Abstract
Hemimelia is a rare anomaly affecting the distal long bones of extremities, with an occurrence of 1-20 cases per million of live births depending on the affected bone. Hemimelia can be an isolated defect or be part of complex syndromes that affect extra skeletal structures. Prenatal detection by routine ultrasound imaging is difficult and yields low detection rates. The prenatal diagnosis of hemimelia should prompt a complete and detailed study of the fetal anatomy, since it can be associated with defects in other structures and systems, as the reported in this case. The prognosis depends upon the associated anomalies., (© 2021 The Authors. Published by the British Institute of Radiology.)

- Abstract
Objective: To evaluate natural history of fetuses congenital diaphragmatic hernia (CDH) prenatally diagnosed in countries where termination of pregnancy is not legally allowed and to predict neonatal survival according to lung area and liver herniation., Methods: Prospective study including antenatally diagnosed CDH cases managed expectantly during pregnancy in six tertiary Latin American centres. The contribution of the observed/expected lung-to-head ratio (O/E-LHR) and liver herniation in predicting neonatal survival was assessed., Results: From the total population of 380 CDH cases, 144 isolated fetuses were selected showing an overall survival rate of 31.9% (46/144). Survivors showed significantly higher O/E-LHR (56.5% vs 34.9%; P < .001), lower proportion of liver herniation (34.8% vs 80.6%, P < .001), and higher gestational age at birth (37.8 vs 36.2 weeks, P < 0.01) than nonsurvivors. Fetuses with an O/E-LHR less than 35% showed a 3.4% of survival; those with an O/E-LHR between 35% and 45% showed 28% of survival with liver up and 50% with liver down; those with an O/E-LHR greater than 45% showed 50% of survival rate with liver up and 76.9% with liver down., Conclusions: Neonatal mortality in CDH is higher in Latin American countries. The category of lung hypoplasia should be classified according to the survival rates in our Latin American CDH registry., (© 2019 John Wiley & Sons, Ltd.)

- Abstract
Objective: To demonstrate changes in hepatic volume and vascular indices in fetuses with intrauterine growth restriction (IUGR) compared with normal-growth fetuses, using a noninvasive method (three-dimensional power Doppler ultrasound)., Methods: The present cross-sectional study was conducted between September 1 and November 30, 2014, at a maternal-fetal medicine unit in Bogotá, Colombia; it included consecutive women at 24-34 weeks of pregnancy. The fetal liver volume and indices of hepatic vascularization were determined with three-dimensional power Doppler ultrasonography and compared between fetuses with and without a diagnosis of IUGR. Results A total of 119 women met study inclusion criteria; 97 fetuses had no growth restriction, whereas 22 fetuses had IUGR. The latter group had decreased liver volume (57.85 ± 29.71 mL vs 86.99 ± 31.24 mL; P=0.010) and increased vascular indices (vascularization index, 47.92 ± 34.44 versus 22.46 ± 18.95; flow index, 71.39 ± 42.01 versus 41.11 ± 23.24; vascularization flow index, 47.94 ± 47.96 versus 13.67 ± 22.38; P=0.003 for all comparisons)., Conclusion: Liver volume was decreased and liver vascular indices values were increased in fetuses with IUGR. These findings imply that evaluation of hepatic vascularization with three-dimensional hepatic Doppler could be useful in the diagnosis of IUGR., (© 2018 International Federation of Gynecology and Obstetrics.)

- Abstract
Objectives: The purpose of this study was to establish intracranial translucency reference values in healthy fetuses from a Latin American population., Methods: This work was a cross-sectional retrospective correlational study. A review of sonographic reports from women between gestational ages of 11 weeks and 13 weeks 6 days at 2 health institutes in Bogota, Colombia, whose fetuses had a crown-rump length of 45 to 84 mm was conducted between January 1, 2010, and December 31, 2012. Women with multiple fetuses or with a deceased fetus were excluded., Results: Data corresponding to 1520 obstetric sonographic examinations were included in the statistical analysis. The crown-rump length was between 45 and 84 mm, with a median of 65 mm (interquartile range, 58-73 mm). The median intracranial translucency was 1.7 mm (interquartile range, 1.4-2.2 mm). Different percentiles (1st, 5th, 10th, 25th, 50th, 75th, 90th, 95th, and 99th) were established for each crown-rump length value. A correlation between crown-rump length and intracranial translucency was found, which seemed to be linear. The intracranial translucency value was not significantly correlated with the frontomaxillary angle but was correlated with nuchal translucency, nasal bone length, and metopic suture length., Conclusions: We present normal intracranial translucency values in the first trimester of single gestations with live fetuses in a Latin American population. These values are similar to those described in other populations. The intracranial translucency value was linearly correlated with crown-rump length in fetuses between gestational ages of 11 weeks and 13 weeks 6 days, which is consistent with previous publications, although these data cannot be interpreted independently.

- Abstract
Objective: To establish the prevalence of congenital malformations diagnosed in Maternal-Fetal Medicine Unit of Hospital de San José, Bogotá-Colombia and comparing them to national and international reports., Materials and Methods: Retrospective, descriptive observational where the quantification of all malformed fetuses diagnosed in Maternal-Fetal Medicine Unit from June 2010 to June 2013 was performed., Results: 236 malformed fetuses, a total of 11,914 births, for a prevalence of 1.98% were included at a mean gestational age at diagnosis of 26.7 weeks (SD 7.1 weeks). The most common congenital malformations were at the level of Central Nervous System (CNS) 88 (37%) in total and within them, the most prevalent was ventriculomegaly 16 (7%). Of the 236 malformed fetuses, 165 fetuses (70.2%) had only one affected system 29 (12.3%) 2 compromised systems and 42 (17.5%) over 3 affected systems. Karyotyping was offered to all antenatal patients, however, accepted only 63 (26.7%), and 39 (62%) with normal results and the other aneuploidies were found, having Trisomy 21 as the most common. It was possible to establish a concordance of 86% between the antenatal and postnatal diagnosis. The perinatal mortality found in this study was 34.7%, mainly in fetuses with congenital diaphragmatic hernia 16 cases (88.8%), fetal non-immune hydrops 8 cases (80%), cardiovascular abnormalities 31 cases (46.2%) genitourinary and 13 cases (24%), and fetuses with CNS malformations such as sequence acranea-anencefalia, holoprosencephaly and encephalocele mortality occurred in 100%., Conclusion: In this study the prevalence of congenital anomalies was found comparable to that reported at local and global levels, which were diagnosed and adequately characterized by more than two-thirds by obstetrical ultrasound performed by trained personnel in prenatal diagnosis. Perinatal morbidity and mortality remain high thoracic, cardiovascular, renal and non-immune hydrops congenital anomalies.

- Abstract
Objective: To characterize patients with atypical preeclampsia (PE), in relation to socio-demographic characteristics, clinical presentation, maternal complications and perinatal outcome., Materials and Methods: Between July 1, 2011 and November 30, 2013, a cohort was created of women attended at a Obstetric High-dependency Unit who met criteria for atypical PE: gestational hypertension with severe hypertension or symptoms or laboratory signs suggestive of microangiopathy/hemolysis; normotensive proteinuria with the presence of symptoms or laboratory signs suggestive of microangiopathy/hemolysis; presence of PE or eclampsia or HELLP syndrome appearing after 48 h postpartum, and, PE or eclampsia appearing before 20 weeks of pregnancy., Results: A total of 200 women fulfilling criteria for atypical PE, were included: 61.5% corresponded to non-proteinuric gestational hypertension, 35.5% to normotensive proteinuria and 3% to PE/eclampsia in late postpartum. Criteria for severe maternal morbidity were present in 12% of the cases and there were no maternal deaths. There were 6 perinatal deaths., Conclusion: Atypical preeclampsia is a type of preeclampsia not fully recognized that is associated with maternal and neonatal morbidity, mainly related to smallness-for-gestational-age and low birth weight. Vasospasm symptoms are a key element to detect this condition.

- Abstract
Background: Stillbirth remains a problem; therefore requires delving analyzed to assess their causes and strategies that prevent or decrease., Objective: To establish the frequency, describe the sociodemographic and medical characteristics, and factors associated with fetal death in a high complexity hospital in Bogotá, Colombia., Materials and Methods: A cross-sectional study quantifying stillbirth and associated factors was conducted in the period from January 1, 2010 to December 31, 2013., Results: There were 112 fetal deaths, from a total of 15408 births, for a fetal mortality rate of 7.3 per 1000 live births. The average age of the patients was 27.9 years (SD 7.7), 70.5 % of fetal deaths occurred in mothers aged 20-35 years, in primigravidae (33%), between 20 and 28 weeks gestational age (42.9%), in fetuses with weights between 500 and 1000 gr (47.8%). The most frequent medical history was hypothyroidism (5.4%) and chronic hypertension (4.5%). The most common diseases associated with pregnancy were oligohydramnios (21.4%), hypertensive disorders of pregnancy (17%), intrauterine growth restriction (IUGR) (17%), and polyhydramnios (16.9%). The most frequently altered test for evaluation of fetal wellbeing was the absent or decreased fetal movements (44.6%), autopsy was performed in 45.5% of cases being the main reported causes of death, chorioamnionitis (21.5%) and placental insufficiency (15.6%)., Conclusion: Stillbirth remains a prevalent problem, our findings suggest the need to develop methods to implement the fetal surveillance in patients with risk factors in order to make timely decisions.
