Abstract
BACKGROUND The 22q11.2 deletion syndrome is the most common microdeletion syndrome and is frequently associated with congenital heart disease. Prenatal diagnosis of 22q11.2 deletion syndrome is increasingly offered. It is unknown whether there is a clinical benefit to prenatal detection as compared with postnatal diagnosis. OBJECTIVE This study aimed to determine differences in perinatal and infant outcomes between patients with prenatal and postnatal diagnosis of 22q11.2 deletion syndrome. STUDY DESIGN This was a retrospective cohort study across multiple international centers (30 sites, 4 continents) from 2006 to 2019. Participants were fetuses, neonates, or infants with a genetic diagnosis of 22q11.2 deletion syndrome by 1 year of age with or without congenital heart disease; those with prenatal diagnosis or suspicion (suggestive ultrasound findings and/or high-risk cell-free fetal DNA screen for 22q11.2 deletion syndrome with postnatal confirmation) were compared with those with postnatal diagnosis. Perinatal management, cardiac and noncardiac morbidity, and mortality by 1 year were assessed. Outcomes were adjusted for presence of critical congenital heart disease, gestational age at birth, and site. RESULTS A total of 625 fetuses, neonates, or infants with 22q11.2 deletion syndrome (53.4% male) were included: 259 fetuses were prenatally diagnosed (156 [60.2%] were live-born) and 122 neonates were prenatally suspected with postnatal confirmation, whereas 244 infants were postnatally diagnosed. In the live-born cohort (n=522), 1-year mortality was 5.9%, which did not differ between groups but differed by the presence of critical congenital heart disease (hazard ratio, 4.18; 95% confidence interval, 1.56-11.18; P<.001) and gestational age at birth (hazard ratio, 0.78 per week; 95% confidence interval, 0.69-0.89; P<.001). Adjusting for critical congenital heart disease and gestational age at birth, the prenatal cohort was less likely to deliver at a local community hospital (5.1% vs 38.2%; odds ratio, 0.11; 95% confidence interval, 0.06-0.23; P<.001), experience neonatal cardiac decompensation (1.3% vs 5.0%; odds ratio, 0.11; 95% confidence interval, 0.03-0.49; P=.004), or have failure to thrive by 1 year (43.4% vs 50.3%; odds ratio, 0.58; 95% confidence interval, 0.36-0.91; P=.019). CONCLUSION Prenatal detection of 22q11.2 deletion syndrome was associated with improved delivery management and less cardiac and noncardiac morbidity, but not mortality, compared with postnatal detection.

Abstract
BACKGROUND Cordocentesis is used in clinical situations in which lower-risk diagnostic procedures do not deliver the desired results. The aim of this study was to evaluate the risk for procedure-related complications and fetal loss in correlation to maternal risk factors. METHODS This is a multicenter retrospective study investigating the complications, risk factors and perinatal outcome of diagnostic cordocentesis between 1998 and 2019 in three different centers. RESULTS A total of 1806 cordocenteses were performed and procedure-related complications (IUFD within 48 h, contractions, bradycardia, unsuccessful puncture, chorioamniotic separation) were noted in 1.6% of cases. Fetuses with chromosomal aberrations, intrauterine growth restriction and hydropic fetuses had a significantly higher rate of fetal loss compared to other indications. Fetal blood sampling (FBS) performed before 17+0 weeks of gestation was associated with a higher risk of procedure-related complications. Maternal BMI ≥ 40 increased the risk for fetal loss, whereas maternal age, number of previous miscarriages, number of previous abortions, history of vaginal bleeding or nicotine abuse did not affect the risk for complications or overall fetal loss rate. CONCLUSIONS In the hands of experienced operators, FBS is a safe way to further fetal diagnostics, and the risk of complications is low.

Abstract
OBJECTIVE We aimed to investigate how the presence of fetal anomalies and different X chromosome variants influences Cell-free DNA (cfDNA) screening results for monosomy X. METHODS From a multicenter retrospective survey on 673 pregnancies with prenatally suspected or confirmed Turner syndrome, we analyzed the subgroup for which prenatal cfDNA screening and karyotype results were available. A cfDNA screening result was defined as true positive (TP) when confirmatory testing showed 45,X or an X-chromosome variant. RESULTS We had cfDNA results, karyotype, and phenotype data for 55 pregnancies. cfDNA results were high risk for monosomy X in 48/55, of which 23 were TP and 25 were false positive (FP). 32/48 high-risk cfDNA cases did not show fetal anomalies. Of these, 7 were TP. All were X-chromosome variants. All 16 fetuses with high-risk cfDNA result and ultrasound anomalies were TP. Of fetuses with abnormalities, those with 45,X more often had fetal hydrops/cystic hygroma, whereas those with "variant" karyotypes had different anomalies. CONCLUSION Both, 45,X or X-chromosome variants can be detected after a high-risk cfDNA result for monosomy X. When there are fetal anomalies, the result is more likely a TP. In the absence of fetal anomalies, it is most often an FP or X-chromosome variant.

Abstract
OBJECTIVE Omphalocele is known to be associated with genetic anomalies like trisomy 13, 18 and Beckwith-Wiedemann syndrome, but not with Turner syndrome (TS). Our aim was to assess the incidence of omphalocele in fetuses with TS, the phenotype of this association with other anomalies, their karyotype, and the fetal outcomes. METHOD Retrospective multicenter study of fetuses with confirmed diagnosis of TS. Data were extracted from a detailed questionnaire sent to specialists in prenatal ultrasound. RESULTS 680 fetuses with TS were included in this analysis. Incidence of small omphalocele in fetuses diagnosed ≥12 weeks was 3.1%. Including fetuses diagnosed before 12 weeks, it was 5.1%. 97.1% (34/35) of the affected fetuses had one or more associated anomalies including increased nuchal translucency (≥3 mm) and/or cystic hygroma (94.3%), hydrops/skin edema (71.1%), and cardiac anomalies (40%). The karyotype was 45,X in all fetuses. Fetal outcomes were poor with only 1 fetus born alive. CONCLUSION TS with 45,X karyotype but not with X chromosome variants is associated with small omphalocele. Most of these fetuses have associated anomalies and a poor prognosis. Our data suggest an association of TS with omphalocele, which is evident from the first trimester.

Abstract
PURPOSE To establish the prevalence of chromosomal aberrations in fetuses with an apparently isolated agenesis of the corpus callosum (ACC) on prenatal ultrasound. MATERIALS & METHODS This was a retrospective study of complete isolated ACC at the time of ultrasound evaluation with respect to karyotype information. Within this group, a subgroup with non-malformation minor abnormalities, such as a single umbilical artery (SUA), polyhydramnios or fetal growth restriction (FGR), was investigated. RESULTS Complete ACC was diagnosed in 343 cases. Of them, 143 (41.6 %) were isolated, with 16 fetuses showing additional minor findings. In 76.2 % (109/143) karyotyping was performed. Additional array CGH analysis was performed in 7.7 % (11/143). Chromosomal aberrations were found in 4.6 % (5/109) overall, in 3.1 % (3/98) of those without any additional sonographic findings (all represented mosaic trisomy 8) and in 18.2 % (2/11) of those with minor abnormalities. The prevalence of pathogenic submicroscopic copy number variant (CNV) was 9 % (1/11). CONCLUSION Fetal karyotyping is recommended in ACC, as trisomy 8 mosaicism should be considered despite otherwise unremarkable ultrasound. The role of novel techniques such as array CGH and its implication has to be explored in prospective studies.

Abstract
Type 1 diabetes (T1D) during pregnancy possibly affects the development of the thymus and the maturation of the immune system in the offspring. The aim of the ImmunDiabRisk study was to investigate thymus growth and maternal and fetal immune responses in pregnancies with and without T1D. The thymus circumferences of the fetuses of pregnant women with T1D (n=49) and without diabetes (n=59) were measured using ultrasound around the 29th gestational week and standardized for gestational age. Simultaneously, the frequencies and total numbers of cell markers were analyzed by flow cytometry in maternal peripheral blood, and at birth in umbilical cord blood. The standardized circumference of the thymus was similar in fetuses of mothers with and without T1D (p=0.26). We observed higher numbers of FOXP3 Tregs, memory Tregs, erythrocytes, and lymphocytes in the cord blood from T1D pregnancies (p=0.01, p=0.002, p=0.002 and p=0.02, respectively). The frequencies of CD4+/CD8+ T cells correlated positively in maternal blood and umbilical cord blood of mother-child pairs, as did the levels of neutrophils (Spearman's correlation coefficient r=0.43, p=0.02 for CD4+/CD8+ cells; r=0.46, p=0.03 for neutrophils), while no significant correlations were observed between thymus circumference and any cell markers in the child. Parts of the prenatal immune system seem to develop differently in the offspring of mothers with and without T1D. The correlation of Tregs between maternal blood and cord blood may indicate a significant cross-talk between the maternal and fetal immune system.

Abstract
OBJECTIVE To assess the types and numbers of cases, gestational age at specific prenatal diagnosis and diagnostic accuracy of the diagnosis of skeletal dysplasias in a prenatal population from a single tertiary center. METHODS This was a retrospective database review of type, prenatal and definitive postnatal diagnoses and gestational age at specific prenatal diagnosis of all cases of skeletal dysplasias from a mixed referral and screening population between 1985 and 2007. Prenatal diagnoses were grouped into 'correct ultrasound diagnosis' (complete concordance with postnatal pediatric or pathological findings) or 'partially correct ultrasound diagnosis' (skeletal dysplasias found postnatally to be a different one from that diagnosed prenatally). RESULTS We included 178 fetuses in this study, of which 176 had a prenatal ultrasound diagnosis of 'skeletal dysplasia'. In 160 cases the prenatal diagnosis of a skeletal dysplasia was confirmed; two cases with skeletal dysplasias identified postnatally had not been diagnosed prenatally, giving 162 fetuses with skeletal dysplasias in total. There were 23 different classifiable types of skeletal dysplasia. The specific diagnoses based on prenatal ultrasound examination alone were correct in 110/162 (67.9%) cases and partially correct in 50/162 (30.9%) cases, (160/162 overall, 98.8%). In 16 cases, skeletal dysplasia was diagnosed prenatally, but was not confirmed postnatally (n = 12 false positives) or the case was lost to follow-up (n = 4). The following skeletal dysplasias were recorded: thanatophoric dysplasia (35 diagnosed correctly prenatally of 40 overall), osteogenesis imperfecta (lethal and non-lethal, 31/35), short-rib dysplasias (5/10), chondroectodermal dysplasia Ellis-van Creveld (4/9), achondroplasia (7/9), achondrogenesis (7/8), campomelic dysplasia (6/8), asphyxiating thoracic dysplasia Jeune (3/7), hypochondrogenesis (1/6), diastrophic dysplasia (2/5), chondrodysplasia punctata (2/2), hypophosphatasia (0/2) as well as a further 7/21 cases with rare or unclassifiable skeletal dysplasias. CONCLUSION Prenatal diagnosis of skeletal dysplasias can present a considerable diagnostic challenge. However, a meticulous sonographic examination yields high overall detection. In the two most common disorders, thanatophoric dysplasia and osteogenesis imperfecta (25% and 22% of all cases, respectively), typical sonomorphology accounts for the high rates of completely correct prenatal diagnosis (88% and 89%, respectively) at the first diagnostic examination.

Abstract
The diagnosis, management, and outcome of six consecutive heterokaryotypic monochorionic twins were evaluated. All suspected cases, based on discordant ultrasound findings, underwent amniocentesis of both sacs. Two cases also had chorionic villous sampling (CVS). Dual amniocentesis was superior to CVS in diagnosing heterokaryotypic monochorionic twins. In four cases, the X-chromosome was involved and autosomal aneuploidy was noted in the others. In five cases, the anomalous twin was selectively reduced by cord coagulation. All pregnancies ended with a phenotypically normal liveborn and all children are developing normally at 1-7 years of age.

Abstract
OBJECTIVE To compare the sonographic findings of the nasal bone in fetuses with trisomy 21 with pathomorphological findings to determine whether the bone is truly absent. METHODS Seventeen first-trimester fetuses with trisomy 21 were identified; the median gestational age was 12 weeks (range, 11-14) and the median maternal age was 38 (range, 27-47) years. Transabdominal ultrasound examination, preceding transabdominal chorionic villus sampling (TA-CVS) for karyotyping, included assessment of the fetal nose. The nasal bone was determined to be 'hypoplastic' or 'absent' and its length was measured. All pregnancies underwent termination after diagnosis. Serial sagittal sectioning with hematoxylin and eosin-staining of formalin fixed tissue was performed. RESULTS Of the 17 cases, the nasal bone was sonographically evident, but with severe hypoplasia in 10 cases, absent in six, and in the remaining case it was not able to be assessed due to fetal position. Histomorphologically, in 16 cases a nasal bone was present, detectable by the evidence of an ossification center, and in one case the ossification structure was not clearly visualized. Retrospective review of ultrasound images could identify nasal bones in five of the six cases in which they were initially reported as being absent on ultrasound examination. These were visible, but less distinct and had decreased echogenicity, hence misinterpretation led to the false finding of an absent nasal bone when it was in fact present but hypoplastic. CONCLUSION Sonographic assessment of the fetal nasal bone should not distinguish between 'present' and 'absent', but instead between 'normal' and 'hypoplastic'. For reproducible results it is necessary to standardize the sonographic examination. The sonographic landmarks of the fetal nose are: the nasal bone, the skin above and the cartilaginous tip of the nose.

Abstract
Among 1547 patients undergoing first-trimester prenatal diagnosis, 100 fetal chromosome aberrations were detected. Thirteen of these involved chromosome 18. In two structural abnormalities of chromosome 18, the aberration could be excluded in amniotic fluid cells and two healthy infants were born. Trisomy 18 was not confirmed in amniotic fluid cells in three trisomy 18 mosaics. In eight non-mosaic trisomy 18 first-trimester diagnoses, the diagnosis was excluded by amniotic fluid cells or fetal cultures in four, and confirmed in the remaining four. Diagnosis of chromosome 18 aberrations in the direct preparation should be confirmed in the long-term culture of the chorionic villus sample or by amniotic fluid cultures.

Abstract
Fetal tissues from 16 spontaneous abortions, two terminations, and one perinatal death, 18 of which were associated with maternal human parvovirus B19 infection, were examined for B19 infection by histology and in situ hybridization using a digoxigenin-labeled B19-DNA probe. In 15 spontaneous abortions and one termination, erythroblasts with intranuclear inclusions (lantern cells) reacted with B19-DNA by in situ hybridization. No internal or external fetal malformations were observed. Because 13 (86.7%) spontaneous abortions with lantern cells occurred between the 20th and 28th weeks of gestation, it is postulated that B19 infection may be a particular threat to the fetus during this stage of gestation.

Abstract
The infection with parvovirus B19 during pregnancy causes in 1/3 of the cases an aplastic crisis in the fetus and consecutively generalized fetal hydrops as a result of severe anemia. Some cases of fetal hydrops and intrauterine death are reported. In our two cases, the fetal therapy by intrauterine intravasal transfusion was successful and the children developed normal. The techniques and indications for fetal blood sampling and the method of intrauterine intravasal transfusion are explained.

Abstract
Clostridium perfringens infections in the puerperal period are rare. A 22-year old patient, after caesarean section at another hospital, was admitted to our clinic showing clinical signs of haemolysis, slight uraemia, a crepitation of tissue and sonographical signs of air bubble formation in the uterus. Since clostridium perfringens infections show a high mortality rate, early operative measures under high-dose Penicillin treatment are indicated. In this case, hysterectomy and salpingectomy were performed. Both ovaries were unaffected and could be conserved. In addition, a peritoneal lavage was done. Our patient was discharged as cured after a postoperative course without any complications. There is no evidence in the literature for the efficacy of either antitoxin treatment or a high oxygen therapy.

Abstract
The authors report on prenatal ultrasonic diagnosis of foetal liver cysts with a massively thickened and cystic placenta in the twenty-third week of pregnancy. Karyotyping and serological examination of foetal blood samples of the umbilical vein gave normal results. The liver cysts were tapped twice subsequently, because they displaced other foetal abdominal and thoracic organs. In the thirty-fifth week of pregnancy the foetus died due to malnutrition resulting from the changes of the placenta, the origin of which remained unclear.

Abstract
We report about the diagnostic reliability of a new commercially available human chorionic gonadotropin (hCG) test, a simple hemagglutination test (discriminatory value: 75 U/I), which can be easily performed in any laboratory (Neo-Pregnosticon). Urine samples of 457 patients with unexplained lower abdominal pain and/or abnormal bleeding were analysed. The diagnostic sensitivity and specificity of the test gave values of 0.993 and 1.0, respectively. The predictive value for positive results was 1.0, and for negative results 0.997. By means of this test, we could determine hCG in urine of 40 out of 41 patients with ectopic pregnancy, in contrast to the currently used urine test (Pregnosticon, discriminatory value: 1000 U/I) which was positive in only about 50% of the cases. Due to its accuracy, this simple test will probably replace in the future the more laborious radioimmunological methods for determination of hCG.
