RESUMEN
The resurgence of syphilis and subsequent risk for newborns has been described worldwide; however, European data on this congenital infection is lacking. We report the activity of a multidisciplinary specialized unit assisting a large area in the Southern Italy. A retrospective cohort study has been conducted at the Perinatal and Pediatric Infectious Diseases Units of the Federico II University of Naples, enrolling all newborns and children referred from January 2010 to June 2022 exposed to Treponema pallidum in utero and/or congenitally infected. A total of 323 patients were included in the analysis. Twenty (6.2%) received a diagnosis of confirmed congenital syphilis (CS) and one died. Fifteen CS cases had typical clinical features. Since 2017, the number of referred neonates tripled while the rate of late maternal diagnoses did not significantly differ. When compared with mothers of exposed infants, mothers of CS cases were younger (25 ± 7.2 vs 29.9 ± 6 years, p = 0.041), had less previous pregnancies (0.64 vs 1.11, p = 0.044), and received a diagnosis of syphilis at a later stage of pregnancy (86% vs 20%, from third trimester or later on; p < 0.001). Appropriate maternal therapy was protective against vertical transmission (- 1.2; - 1.4, - 1 95% CI; p < 0.001). Paternal syphilis status was known in 36% of cases. CONCLUSION: CS has still a significant impact. Prevention should be implemented towards specific maternal risk profiles. A specialized unit is the preferable model to improve surveillance and healthcare for this neglected population. WHAT IS KNOWN: ⢠The resurgence of syphilis and subsequent risk for newborns has been described worldwide. ⢠European data on this congenital infection is lacking. WHAT IS NEW: ⢠Congenital syphilis has a significant impact still in Europe and prevention should be implemented towards specific maternal risk profiles. ⢠A specialized unit is the preferable model to improve surveillance and healthcare for this neglected population.

OBJECTIVE: Prenatal diagnosis of the Ectrodactyly-Ectodermal dysplasia-clefting (EEC) syndrome has been based upon the detection of ectrodactyly, in association with facial clefting and/or positive family history. Our aim is to describe other ultrasonographic features indicating the presuntive diagnosis, regardless of genetic diagnosis, especially in cases of negative family history. MATERIALS AND METHODS: A case report and a review of the literature was assessed. RESULTS: Our case report showed a singleton foetus "lobster claw" deformities of hands and feet. Paternal history revealed bilateral agenesia of two fingers. Through literature, 15 case reports of prenatal diagnosis of EEC syndrome were found, 14 of which were eligible for our systematic review. The 33% of cases (5/15) had a familiar history of EEC, thus, we found one case of consanguinity of parents. Anomalies EEC-related were recognized in the 40% of cases (6/15). An association with genitourinary anomalies was found in 30% (5/15) of them. CONCLUSIONS: A strong suspicion of final diagnosis of EEC may be done in the presence of ectrodactyly, facial clefting and urinary malformation especially in cases of negative family history. More attention should be given to a genetic counseling, especially to understand a possible relation to other genetic syndromes.
RESUMEN
BACKGROUND: Heterozygous mutations of the ACAN gene are a major cause of different evolutive growth defects in the pediatric population, but were never described as a cause of fetal skeletal dysplasia. CASE PRESENTATION: A G1 at 21w + 3d came to our institution for the second-trimester ultrasound and a skeletal dysplasia with prevalent involvement of limb's rhizomelic tracts was suspected. Amniocentesis followed by CGH-array was performed, with normal results. An examination by NGS of some genes associated with skeletal dysplasias showed a novel pathogenic variant of the ACAN gene: c.2677delG. CONCLUSION: Sequence variations of ACAN were never described as a possible cause of fetal skeletal anomalies to date. In this case report, we describe the first prenatal diagnosis of skeletal dysplasia associated with a pathogenic variant of ACAN.

BACKGROUND: Gallbladder duplication is a rare anatomic anomaly characterized by the presence of an accessory gallbladder. OBJECTIVE: To appraise the prevalence and significance of prenatal diagnosis of duplication of gallbladder in a multicenter study. METHODS: This was a multicenter case series with literature review. Clinical records of all consecutive pregnant women with a prenatal diagnosis of duplication of gallbladder, who were referred to our Centers were included in this study. The diagnosis of duplication of gallbladder was based on the evidence of double gallbladder in the standard abdominal circumference plane using grey scale. Postnatal magnetic resonance cholangiopancreatography (MRCP) 3D and postnatal neonatal abdominal ultrasound scan were offered soon after birth to confirm the diagnosis of double gallbladder. The systematic review was conducted using electronic databases from inception of each database through December 2019. RESULTS: Five studies, including a total of seven cases, were identified as relevant and included in the systematic review. Gestational age at diagnosis ranged from 20 to 32 weeks of gestation. Associated findings were reported in only one case, where the fetus presented with a left-sided gallbladder, and bilateral renal agenesis with Potter sequence. None of the included cases reported abnormal karyotype. Our cases series included nine cases (0.03%) of double gallbladder with postnatal confirmation, with an overall incidence of this anomaly of 0.03%.Associated findings were reported in only two cases, one with IUGR and omphalocele, that opted for I-TOP, and one with single umbilical artery. Except for the I-TOP, neonatal outcome was favorable in all cases. CONCLUSIONS: Duplication of the gallbladder is a very rare malformation with only seven cases reported in the literature diagnosed prenatally. This anomaly is not associated with abnormal karyotype, and the neonatal outcome is favorable if there are no other associated abnormalities.

Introduction: Vein of Galen malformations (VGMs) account for less than 1% of all intracranial vascular malformations. However, in fetal and pediatric populations, they represent the most common vascular malformation of the brain. For the effective management of this condition, an optimal knowledge of its prenatal and postnatal clinical features is mandatory. Methods: Articles published between 1 January 2003 and 31 January 2024, reported in PubMed and EMBASE, were evaluated for a systematic review analyzing the prenatal and postnatal features and management of fetal VGMs. Results: Thirty-one papers reporting information on 51 prenatally diagnosed VGMs were included. The most common prenatal features were fetal hydrocephalus (39%) and cardiomegaly (56%). Postnatal data for 43 VGM cases are described. The overall mortality was 58.14%. In total, 77.78% of the survivors had normal development. Conclusions: Close follow-up and a multidisciplinary approach are mandatory to manage this condition. Our study aimed to provide a guide for gynecologists, neonatologists, cardiologists, and neuroradiologists.
RESUMEN
Short-rib thoracic dysplasia 3 with or without polydactyly (OMIM # 613091) represents a clinical spectrum encompassing a heterogeneous group of skeletal dysplasias associated with homozygous or compound heterozygous mutations of DYNC2H1. We describe the case of a couple with two consecutive therapeutic abortions due to a diagnosis of short-rib thoracic dysplasia mutations. In the first pregnancy, the diagnosis has been made at 21 weeks. In the second one, an accurate and early ultrasound examination allowed a diagnosis at 12 weeks. DYNC2H1 mutations were confirmed in both cases. In this report, we underline the importance of an ultrasound evaluation at the end of the first trimester of pregnancy in the detection of early signs of skeletal dysplasias. An early prenatal diagnosis of a short-rib skeletal dysplasia, such as for other severe skeletal dysplasias, is critical to offer a couple the chance of a weighted, informed, and less traumatic decision about the continuation of the pregnancy.

INTRODUCTION: A congenital intrathoracic kidney (ITK) is a rare anomaly that is recognized to have four causes: renal ectopia with an intact diaphragm, diaphragmatic eventration, diaphragmatic hernia, and traumatic diaphragmatic rupture. We report a case of a prenatal-diagnosed ITK related to a congenital diaphragmatic hernia (CDH) and conducted a systematic review of all cases of the prenatal diagnosis of this association. CASE PRESENTATION: A fetal ultrasound scan at 22 gestational weeks showed left CDH and ITK, hyperechoic left lung parenchyma, and mediastinal shift. The fetal echocardiography and karyotype were normal. Magnetic resonance imaging at 30 gestational weeks confirmed the ultrasound suspicion of left CDH in association with bowel and left kidney herniation. The fetal growth, amniotic fluid, and Doppler indices remained within the normal range over time. The woman delivered the newborn via an at-term spontaneous vaginal delivery. The newborn was stabilized and underwent non-urgent surgical correction; the postoperative course was uneventful. CONCLUSIONS: CDH is the rarest cause of ITK; we found only eleven cases describing this association. The mean gestational age at diagnosis was 29 ± 4 weeks and 4 days. There were seven cases of right and four cases of left CDH. There were associated anomalies in only three fetuses. All women delivered live babies, the herniated kidneys showed no functional damage after their surgical correction, and the prognosis was favorable after surgical repair. The prenatal diagnosis and counseling of this condition are important in planning adequate prenatal and postnatal management in order to improve neonatal outcomes.
RESUMEN
BACKGROUND AND OBJECTIVES: The present study aims to provide prenatal 2-dimensional ultrasonographic (2D-US) nomograms of the normal cerebellar area. MATERIALS AND METHODS: This is a prospective cross-sectional analysis of 252 normal singleton pregnancies, ranging from 13 to 39 weeks of gestation. The operator performed measurements of the fetal cerebellar area in the transverse plane using 2D-US. The relationship between cerebellar area and gestational age (GA) was determined through regression equations. RESULTS: A significant, strong positive correlation was investigated between the cerebellar area with GA (r-value = 0.89), and a positive correlation indicates that with increasing GA, the cerebellar area increased in all the participants of the study. Several 2D-US nomograms of the normal cerebellar area were provided, and an increase of 0.4% in the cerebellar area each week of GA was reported. CONCLUSIONS: We presented information on the typical dimensions of the fetal cerebellar area throughout gestation. In future studies, it could be evaluated how the cerebellar area changes with cerebellar abnormalities. It should be established if calculating the cerebellar area in addition to the routine transverse cerebellar diameter may help in discriminating posterior fossa anomalies or even help to identify anomalies that would otherwise remain undetected.
RESUMEN
Enteric duplication cysts are rare congenital malformations of the gastrointestinal tract. Prenatal diagnosis can be achieved through ultrasound, which may reveal a cystic mass, though the differential diagnosis is broad. We report a case in which the prenatal ultrasound detection of an abdominal cystic mass prompted postnatal magnetic resonance imaging, leading to the diagnosis of an enteric duplication cyst. At 6 weeks of age, the infant developed an obstruction of the small bowel, requiring urgent surgical intervention. This case underscores the difficulties in differentiating abdominal cysts prenatally. Thorough prenatal and neonatal follow-up is crucial, and postnatal magnetic resonance imaging is sometimes essential for accurate diagnosis. The clinical course can be unpredictable, and complications that may arise could necessitate urgent surgical treatment.
RESUMEN
BACKGROUND: Valacyclovir is the only treatment demonstrated to be effective for the prevention of vertical transmission of cytomegalovirus within a clinical randomized, placebo-controlled trial and has been reimbursed by the Italian National Health System since December 2020. OBJECTIVE: This study reported the results of a real-life Italian multicenter observational study on cytomegalovirus infection in pregnancy evaluating the effect of the introduction of valacyclovir in the clinical practice for the prevention of vertical transmission of cytomegalovirus. STUDY DESIGN: The outcomes of women who received valacyclovir treatment and their fetuses or newborns were compared with those of a retrospective cohort observed between 2010 and 2020 who did not receive the antiviral treatment. The inclusion criterion was the diagnosis of cytomegalovirus primary infection occurring in the periconceptional period or up to 24 weeks of gestation. The primary outcome was the transmission by the time of amniocentesis. The secondary outcomes were termination of pregnancy, transmission at birth, symptomatic infection at birth, and a composite outcome (termination of pregnancy or transmission at birth). RESULTS: A total of 447 pregnant women from 10 centers were enrolled, 205 women treated with valacyclovir (called the valacyclovir group, including 1 twin pregnancy) and 242 women not treated with valacyclovir (called the no-valacyclovir group, including 2 twin pregnancies). Valacyclovir treatment was significantly associated with a reduction of the diagnosis of congenital cytomegalovirus infection by the time of amniocentesis (weighted odds ratio, 0.39; 90% confidence interval, 0.22-0.68; P=.005; relative reduction of 61%), termination of pregnancy (weighted odds ratio, 0.36; 90% confidence interval, 0.17-0.75; P=.0021; relative reduction of 64%), symptomatic congenital cytomegalovirus infection at birth (weighted odds ratio, 0.17; 90% confidence interval, 0.06-0.49; P=.006; relative reduction of 83%). The treatment had no significant effect on the rate of diagnosis of congenital cytomegalovirus infection at birth (weighted odds ratio, 0.85; 90% confidence interval, 0.57-1.26; P=.500), but the composite outcome (termination of pregnancy or diagnosis of congenital cytomegalovirus infection at birth) occurred more frequently in the no-valacyclovir group (weighted odds ratio, 0.62; 90% confidence interval, 0.44-0.88; P=.024). Of note, the only symptomatic newborns with congenital cytomegalovirus infection in the valacyclovir group (n=3) were among those with positive amniocentesis. Moreover, 19 women (9.3%) reported an adverse reaction to valacyclovir treatment, classified as mild in 17 cases and moderate in 2 cases. Lastly, 4 women (1.9%) presented renal toxicity with a slight increase in creatinine level, which was reversible after treatment suspension. CONCLUSION: Our real-life data confirm that valacyclovir significantly reduces the rate of congenital cytomegalovirus diagnosis at the time of amniocentesis with a good tolerability profile and show that the treatment is associated with a reduction of termination of pregnancy and symptomatic congenital cytomegalovirus infection at birth.
RESUMEN
INTRODUCTION: The aim of this study was to evaluate the incidence of toxoplasmosis infection during pregnancy and to describe the characteristics of the serological status, management, follow-up and treatment. MATERIAL AND METHODS: This is a population-based cohort study of women referred for suspected toxoplasmosis during pregnancy from January, 2001 to December, 2012. Suspected toxoplasmosis was defined as positive IgM antibody during pregnancy. Women with suspected toxoplasmosis during pregnancy were classified into three groups: seroconversion, suspected infection, or no infection in pregnancy. Women in the first and second group were treated according to local protocol, and amniocentesis with toxoplasmosis PCR detection and serial detailed ultrasound scans were offered. Neonates were investigated for congenital toxoplasmosis at birth and were monitored for at least one year after birth. RESULTS: During the study period, there were 738,588 deliveries in Campania. Of them 1159 (0.2%) were referred to our Institution for suspected toxoplasmosis during pregnancy: 183 (15.8%) women were classified as seroconversion, 381 (32.9%) were suspected infection, and 595 (51.3%) were not infected in pregnancy. Neonatal outcome was available for 476 pregnancies, including 479 neonates (3 twins, 473 singletons), out of the 564 pregnancies with seroconversion or suspected infection. 384 (80.2%) babies were not infected at birth and at follow-up, 67 (14.0%) had congenital toxoplasmosis, 10 (2.1%) were voluntary induced termination of pregnancy, 15 (3.1%) were spontaneous miscarriage, and 4 (0.8%) were stillbirth (of which one counted already in the infected cohort). Considering cases of congenital toxoplasmosis, the transmission rate in women with seroconversion was 32.9% (52/158), and in women with suspected infection was 4.7% (15/321). CONCLUSIONS: Toxoplasmosis is uncommon in pregnancy with overall incidence of seroconversion and suspected infection in pregnancy of 0.8 per 1000 live births and incidence of congenital toxoplasmosis 0.1 per 1000 live births when applying a strict protocol of screening, follow-up, and treatment. 51.3% (595/1159) of women referred to our center for suspected infection were actually considered not infected.

INTRODUCTION: Congenital absence of the ductus venosus (ADV) is a rare vascular anomaly often associated with fetal cardiac and extracardiac anomalies, aneuploidies, and hydrops. The prognosis depends on the patterns of abnormal venous circulation, on the associated malformations and on chromosomal aberrations. METHODS: We performed a retrospective audit of all consecutive cases with ADV referred in our centres and analysed the outcomes. RESULTS: A total of six cases with prenatally diagnosed ADV were identified. The gestational age at diagnosis ranged from 15 to 35 weeks. Karyotyping was performed in all cases. Normal karyotype was found in five out of the six cases. Overall, four neonates survived at 28 days follow-up. The other two died 48 h after delivery: both of them had extrahepatic ADV. DISCUSSION: Absence of the ductus venosus may be compatible with normal fetal development without relevant disturbance of circulation and oxygenation independently from type of abnormal venous circulation.

OBJECTIVE: To evaluate pregnancy outcome in preeclampsia (PE), according to the timing of onset of proteinuria and hypertension. METHODS: Preeclamptic women were retrospectively divided into proteinuria-onset and hypertension-onset PE according to the first symptom. Maternal and perinatal outcome were assessed in both the groups. RESULTS: One hundred and ninety five single pregnancies complicated by PE were included. According to the first symptom, they were divided into two groups: proteinuria-onset PE (n = 49, 25.1%) and hypertension-onset PE (n = 146, 74.9%). Pregnancy and neonatal outcome was significantly worse in proteinuria-onset PE. CONCLUSION: Proteinuria-onset PE is associated with an increased risk of adverse pregnancy outcome than hypertension-onset PE.

OBJECTIVE: the purpose of this paper is to report the first case of megaurethra in a fetus with Meckel syndrome and in a fetus with femal pseudoermaphroditism. RESULTS: the former case refers to a fetus of 13 weeks gestation with the three following prominent anomalies, observed by transonic scan and confirmed by autopsy: congenital megaurethra, anal atresia, single umbelical artery. The latter case refers to a fetus of 18 weeks gestation. Autopsy confirmed penile malformation and revealed ovaries in the abdomen. The karyotype was 46,XX with normal molecular karytype. The megaurethra was discovered by sonography at 18 weeks gestation. Autopsy confirmed penile malformation and revealed ovaries in the abdomen. The karyotype was 46,XX with normal molecular karyotype (Array-CGH, 1 Mb of resolution). METHODS: transonic scan, autopsy, karyotype, array-CGH. CONCLUSIONS: the first prenatal cases of two genetic syndromes with megaurethra have been reported, concening respectively a fetus with Meckel syndrome and a fetus with femal pseudoermaphroditism. The latter was confirmed by both autopsy and the normal female 46,XX karyotype.
RESUMEN
OBJECTIVE: Women with chronic kidney disease have an increased risk of developing preeclampsia and its severe complications. Currently, there are no assessments available in order to quantify such risk. The aim of the study is to establish the incidence of superimposed preeclampsia in women with chronic kidney disease according to Serum creatinine (SCr) level. METHODS: Pregnant women with chronic kidney disease were retrospectively identified from January 2000 to July 2010. We defined two groups according to SCr: Group 1: SCr ≤ 125 µmol/l; Group 2: SCr > 125 µmol/l. Incidence of preeclampsia, early preeclampsia (delivery <34 weeks), gestational age (GA) at diagnosis and delivery outcome were assessed. RESULTS: Ninety-three nephropatic women were considered for the analysis. Group 2 (n = 14) compared with Group 1 (n = 79) had an increased incidence of preeclampsia (78.6% vs. 25.3%; p < 0.0001), an increased rate of pregnancy complications as early preeclampsia (82% vs. 38%; p < 0.03), a lower GA at diagnosis (29 ± 2 vs. 33 ± 1 weeks; p < 0.04) and a lower GA at delivery (30 ± 2 weeks vs. 34 ± 1; p < 0.04). CONCLUSION: Women with chronic kidney disease and an increased creatinine threshold have a high risk of developing preeclampsia and delivering preterm.

In the past, pregnancy was contraindicated in patients with spinal muscular atrophy. Recently, more cases are occurring because of improvement in survival and functional status. The goals for anesthetic management of these patients include satisfactory anesthesia during surgery and excellent postoperative analgesia with minimal compromise of respiratory function. Spinal anesthesia may be considered contraindicated due to spinal deformities, but successful spinal anesthesia was performed in a 37 year old parturient following magnetic resonance imaging of the spine.
