Monochorionic-diamniotic twin pregnancy complicated by spontaneous septostomy and cord entanglement. a systematic review, evaluation of complication rates and presentation of an additional case

Background: Our purpose is to describe the ultrasound findings, both with bi-dimensional and three-dimensional imaging, suggestive of spontaneous septostomy in monochorionic-diamniotic twin pregnancies. Methods: PubMed, Medline and reference lists were searched using “Spontaneous septostomy and twin pregnancy” as keywords. Seventeen articles reporting a total of 25 cases, adding our own, were included in the systematic review. Only English full text articles, the main purpose of which was to describe spontaneous septostomy in twin pregnancies, were included. Results: In our sample the major ultrasound sign arousing suspicion of spontaneous septostomy was found to be an absent or disrupted inter-twin membrane (79% of cases). Twins close to each-other were described in 33% of cases, while cord entanglement was suspected only in 27% of cases. We reported a lower antenatal detection of entanglement when compared with intrapartum evaluation (27% vs 59%). Adverse fetal outcomes occurred in 12% of cases, while 88% of cases were born alive. Conclusions: Spontaneous septostomy represents a diagnostic and clinical challenge for obstetrics providers. Clinicians must focus on ultrasound findings to close surveil fetal wellness and reduce both fetal and neonatal impairment

Use of deferoxamine (DFO) in transfusion-dependent β-thalassemia during pregnancy: A retrospective study.

Objective: To report cases of use of chelation therapy during pregnancy which resulted in favorable outcomes for the babies. Materials and methods: In this retrospective cohort study, we described the evolution and outcome of 9 pregnancies in Italian thalassemic women who received deferoxamine (DFO) inadvertently during early pregnancy. Results: The use of deferoxamine during first trimester did not lead to adverse effects on the fetus or cause major complications for the gestation, although an increase in iron burden was observed after suspending chelation therapy. Conclusion: In our experience, iron-chelation therapy might be administrated in pregnancy where the benefits to the mother outweigh the potential risks to the baby.

Echocardiographic features and outcome of restrictive foramen ovale in fetuses with and without cardiac malformations. literature review

Foramen ovale is a small communication between the left and the right atrium and its restriction is a rare congenital heart anomaly. There is no consensus on diagnosis and management of fetal restrictive foramen ovale (RFO). In our paper we included 11 studies about fetuses affected by isolated RFO, RFO with D-Transposition of the Great Arteries (dTGA) and RFO with hypoplastic left heart syndrome (HLHS). While fetuses affected from HLHS and dTGA with RFO have a poor prognosis, premature RFO in an otherwise structurally normal heart, if found in later gestation, have an overall good outcome

Risk factors associated with adverse fetal outcomes in pregnancies affected by Coronavirus disease 2019 (COVID-19): a secondary analysis of the WAPM study on COVID-19.

Objectives To evaluate the strength of association between maternal and pregnancy characteristics and the risk of adverse perinatal outcomes in pregnancies with laboratory confirmed COVID-19. Methods Secondary analysis of a multinational, cohort study on all consecutive pregnant women with laboratory-confirmed COVID-19 from February 1, 2020 to April 30, 2020 from 73 centers from 22 different countries. A confirmed case of COVID-19 was defined as a positive result on real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens. The primary outcome was a composite adverse fetal outcome, defined as the presence of either abortion (pregnancy loss before 22 weeks of gestations), stillbirth (intrauterine fetal death after 22 weeks of gestation), neonatal death (death of a live-born infant within the first 28 days of life), and perinatal death (either stillbirth or neonatal death). Logistic regression analysis was performed to evaluate parameters independently associated with the primary outcome. Logistic regression was reported as odds ratio (OR) with 95% confidence interval (CI). Results Mean gestational age at diagnosis was 30.6+/-9.5 weeks, with 8.0% of women being diagnosed in the first, 22.2% in the second and 69.8% in the third trimester of pregnancy. There were six miscarriage (2.3%), six intrauterine device (IUD) (2.3) and 5 (2.0%) neonatal deaths, with an overall rate of perinatal death of 4.2% (11/265), thus resulting into 17 cases experiencing and 226 not experiencing composite adverse fetal outcome. Neither stillbirths nor neonatal deaths had congenital anomalies found at antenatal or postnatal evaluation. Furthermore, none of the cases experiencing IUD had signs of impending demise at arterial or venous Doppler. Neonatal deaths were all considered as prematurity-related adverse events. Of the 250 live-born neonates, one (0.4%) was found positive at RT-PCR pharyngeal swabs performed after delivery. The mother was tested positive during the third trimester of pregnancy. The newborn was asymptomatic and had negative RT-PCR test after 14 days of life. At logistic regression analysis, gestational age at diagnosis (OR: 0.85, 95% CI 0.8-0.9 per week increase; pPeer reviewe

Maternal and perinatal outcomes of pregnant women with SARS-CoV-2 infection

Objectives To evaluate the maternal and perinatal outcomes of pregnancies affected by SARS-CoV-2 infection. Methods This was a multinational retrospective cohort study including women with a singleton pregnancy and laboratory-confirmed SARS-CoV-2 infection, conducted in 72 centers in 22 different countries in Europe, the USA, South America, Asia and Australia, between 1 February 2020 and 30 April 2020. Confirmed SARS-CoV-2 infection was defined as a positive result on real-time reverse-transcription polymerase chain reaction (RT-PCR) assay of nasopharyngeal swab specimens. The primary outcome was a composite measure of maternal mortality and morbidity, including admission to the intensive care unit (ICU), use of mechanical ventilation and death. Results In total, 388 women with a singleton pregnancy tested positive for SARS-CoV-2 on RT-PCR of a nasopharyngeal swab and were included in the study. Composite adverse maternal outcome was observed in 47/388 (12.1%) women; 43 (11.1%) women were admitted to the ICU, 36 (9.3%) required mechanical ventilation and three (0.8%) died. Of the 388 women included in the study, 122 (31.4%) were still pregnant at the time of data analysis. Among the other 266 women, six (19.4% of the 31 women with first-trimester infection) had miscarriage, three (1.1%) had termination of pregnancy, six (2.3%) had stillbirth and 251 (94.4%) delivered a liveborn infant. The rate of preterm birth before 37 weeks' gestation was 26.3% (70/266). Of the 251 liveborn infants, 69/251(27.5%) were admitted to the neonatal ICU, and there were five (2.0%) neonatal deaths. The overall rate of perinatal death was 4.1% (11/266). Only one (1/251, 0.4%) infant, born to a mother who tested positive during the third trimester, was found to be positive for SARS-CoV-2 on RT-PCR. Conclusions SARS-CoV-2 infection in pregnant women is associated with a 0.8% rate of maternal mortality, but an 11.1% rate of admission to the ICU. The risk of vertical transmission seems to be negligible. (C) 2020 International Society of Ultrasound in Obstetrics and Gynecology.Peer reviewe

Redundancy of the foramen ovale flap may mimic aortic coarctation in the fetus.

Objective: Aim of this study is to assess the relationships between a redundant foramen ovale flap (RFOF) - in the absence of a clearly restrictive foramen ovale - and ventricular disproportion in three group of foetuses: 1) foetuses with a final diagnosis of aortic coarctation (CoA); 2) foetuses referred for a suspicion of ventricular disproportion and/or CoA who did not develop CoA postnatally; 3) normal foetuses. Methods: This is a retrospective study including 73 fetuses, allotted to three groups: 1) foetuses with a final diagnosis of isolated CoA (12 cases); 2) foetuses referred for a suspicion of ventricular disproportion and/or CoA who did not develop CoA postnatally (30 cases); 3) normal foetuses (31 cases). Four-dimensional volume datasets and clips were assessed offline. Diameters of the flap valve, left and right atrium, left and right ventricle and, where available, aortic isthmus and arterial duct were measured; areas of the flap valve, left and right atria and ventricles were measured, too. The left/right ratios for all segments of the heart as well as the ratio between flap diameter / left atrium diameter (FOFD/LAD ratio) and flap area / left atrium area were calculated. Regression analysis was performed to assess the relationships between FOF redundancy and ventricular disproportion. Means were compared with the ANOVA test. Results: Repeatability was fair, with all variables showing an ICC > 83%. In the pooled group of of normals or ventricular disproportion (61 cases), there was a linear correlation between prominence of the FOF and degree of ventricular disproportion (p < 0.01 and p < 0.05 for diameters' and areas' ratios, respectively). Categorising the FOF prominence, cases with FOFd/LAd ratio ≥ 0.65 were highly associated with ventricular disproportion (p = 0.006) Based on the degree of FOF prominence, 4 categories were described, ranging from no prominence/no ventricular disproportion (Stage 0) to severe prominence/ventricular disproportion + transient obstruction of the foramen ovale or mitral orifice. Then, comparing cases with FOFd/LAd ratio ≥ 0.65 vs those with neonatal evidence of coarctation, there was no statistically significant difference in degree of ventricular disproportion nor in the z-score of the aortic isthmus. Conclusions: This study demonstrates that: 1) there is an association between RFOF and ventricular disproportion, independently of the association with a restrictive foramen ovale, and 2) the presence of a RFOF may fully simulate CoA. In fact, it determines both ventricular disproportion and a significant reduction in the diameter of the aortic isthmus, associated in some cases also with reverse isthmic flow. Future prospective studies are needed to evaluate whether focusing the sonologist's attention on the aspect of the FOV may reduce the rate of false positive diagnoses for CoA

Diagnosis & management of imported malaria in pregnant women in non-endemic countries

Malaria in pregnancy is an important cause of maternal and foetal morbidity and is a potentially life-threatening infection. With ever-growing global exchanges, imported malaria in pregnancy is becoming an issue of concern in non-endemic countries where women, because of low immunity, have higher risk of severe diseases and death. Malaria in pregnancy is a dangerous condition which can be associated with important consequences for both mother and child such as stillbirth, low birth weight, maternal anaemia. In non-endemic-countries it is more frequent in its severe form which can lead to maternal death if not treated adequately. Specific anti-malarial interventions such as the use of repellents and insecticide treated bed nets in addition to chemoprophylaxis should be used by pregnant women if they are travelling to endemic areas. In cases of confirmed infection, specific treatment regimens vary according to gestational age and the presence of complications. Malaria should be considered a global health problem, increasingly involving western countries. Clinicians all over the world need to be prepared for this emerging disease both in terms of prevention and therapy

Bartholin gland cancer

INTRODUCTION: Bartholin gland carcinoma is an extremely rare condition. Because of its, phase III trials have not been carried out, there exists no unanimous consensus on treatment and guidelines are missing. METHODS: All studies reporting cases of Bartholin cancer were collected and screened for the evaluations. Baseline characteristics of studies were extracted and were queried in a database. RESULTS: A total number of 133 manuscripts collected were available for the review process, representing a total number of 275 reported cases. The histological type of Bartholin gland cancer was specified in 90.4% cases: 30.7% cases were squamous cell carcinoma, 29.6% adenoid cystic carcinoma, 25% adenocarcinomas. At multivariate analysis adenocarcinoma histotype and positive lymph node were statistical correlated with worse prognosis. CONCLUSION: Bartholin gland cancer remains a challenge for gynecologic oncologists. To better understand and treat this disease, centralization to referral centers and design of multi institutional trials is crucial
