- Abstract
BACKGROUND: Fetal fibronectin (FFN) in cervical secretion is one of the most effective markers of pre-term and term delivery. The presence of FFN in cervicovaginal secretions has recently been shown to reflect cervical state and an uncomplicated induction of labor at term. This study was designed to determine whether FFN could be a biochemical marker to predict the response to prostaglandins in early mid-trimester abortion. METHODS: The presence of cervical FFN was evaluated by means of qualitative rapid immunoassay in 270 patients, who required second trimester termination of pregnancy at the Department of Gynecology and Obstetrics, University of Naples 'Federico II'. According to the standard protocol of our unit, women received 1.0 mg of gemeprost intravaginally at 3-hr intervals up to a maximum of five suppositories. The induction-to-abortion interval and the percentage of successful abortions within 24 hr in women in the positive FFN group (n=19) were compared with those in the negative FFN group (n=251). RESULTS: FFN in the cervical secretions was present in seven women (10.2%) at 16-weeks gestation, in seven women (7.5%) at 17-weeks gestation, and in five women (4.5%) at 18-week gestation. Final termination rates were 13 (68.4%) in the fibronectin-positive group and 177 (70.5%) in the fibronectin-negative group. The median abortion interval was similar (14.7 versus 15.1 hr) in both groups. CONCLUSIONS: A positive cervical fetal fibronectin test does not predict a successful medical termination of pregnancy in second trimester abortion. In this setting, the role of fetal cervical fibronectin in cervical ripening is, therefore, questionable.

The detailed study of the fetal cardiac anatomy in the first trimester of pregnancy by means of ultrasound is feasible whether using a transvaginal or a transabdominal approach. There is nowadays enough evidence that ultrasound in the first trimester of pregnancy is a safe procedure provided thermal and mechanical indices are taken into account. The best timing for successful imaging of the four chambers and great arteries in early gestation appears to be between around 13 to 14 weeks rather than 11 to 12 weeks. In experienced hands, first-trimester fetal echocardiography is quite sensitive for the detection of major structural cardiac abnormalities. Besides the nasal bone, markers for first trimester screening of chromosomal abnormalities such as nuchal translucency thickness, the flow in the ductus venosus and the flow through the tricuspid valve constitute also markers for cardiac abnormalities. The finding of an increased nuchal translucency, an abnormal flow in the ductus venosus or a tricuspid regurgitation constitutes an indication for more detailed fetal cardiac assessment. Other indication for a detailed cardiac assessment is the finding of an aberrant right subclavian artery and vascular anomalies. The emerging importance of these markers has caused renewed interest in the early study of the fetal heart.

Pentalogy of Cantrell is a rare congenital anomaly consisting of the following features: 1) midline supraumbilical abdominal wall defects; 2) deficiency of the anterior diaphragm; 3) defects in the diaphragmatic pericardium; 4) defects of the lower sternum; 5) congenital intracardiac defects. We report 3 cases of pentalogy of Cantrell diagnosed respectively at 13, 18 and 24 weeks of gestation. In case 1 Cantrell's pentalogy was diagnosed during the 1(st) trimester. Case 2 revealed the coexistence of cystic hygroma. Case 3 showed an association with dysplastic left kidney and mild pyelectasis of the right kidney. Our results confirm the possibility of an early detection of Cantrell's pentalogy and reveal the possibility of associations with other pathological findings.

Objectives To compare prospectively maternal acceptance of fetal and neonatal virtuopsy with that of conventional autopsy and to determine the confidence with which magnetic resonance (MR) virtuopsy can be used to diagnose normality/abnormality of various fetal anatomical structures. Methods MR and/or computed tomography virtuopsy and conventional autopsy were offered to 96 women (102 fetuses/neonates) following termination of pregnancy (TOP), intrauterine fetal death (IUFD) or neonatal death. Multivariable logistic regression analysis was used to investigate the effect on maternal acceptance of virtuopsy and/or conventional autopsy of the age of the mother, gestational age at TOP or delivery after IUFD, order of pregnancy, parity, religion, type of caregiver obtaining consent and reason for death. When parents consented to both MR virtuopsy and conventional autopsy of fetuses = 20 weeks of gestation or neonates, the confidence with which MR virtuopsy could be used to diagnose normality/abnormality of variousanatomical structures was determined on a scale in which conventional autopsy was considered gold standard. On autopsy we classified fetuses/neonates as having either normal or abnormal anatomical structures; these groups were analyzed separately. At virtuopsy, we indicated confidence of diagnosis of normality/abnormality of every anatomical structure in each of these two groups defined at autopsy, using a scale from 0 (definitely abnormal) to 100 (definitely normal). Results Of the 96 women, 99% (n = 95) consented to virtuopsy and 61.5% (n = 59) to both conventional autopsy and virtuopsy; i.e. 36 (37.5%) consented to virtuopsy alone. Maternal acceptance of conventional autopsy was independently positively related to singleton pregnancy, non-Moslem mother, earlier gestation at TOP or delivery afer IUFD and a maternalfetal medicine specialist obtaining consent. Thirty-three fetuses = 20 weeks of gestation had both conventional autopsy and MR virtuopsy, of which 19 had a full autopsy including the brain. In fetuses with normal anatomical structures at conventional autopsy, MR virtuopsy was associated with high diagnostic confidence (scores > 80) for the brain, skeleton, thoracic organs except the heart, abdominal organs except the pancreas, ureters, bladder and genitals. In fetuses with abnormal anatomical structures at autopsy, MR virtuopsy detected the anomalies with high confidence (scores

Introduction: The objective of the study was to provide more detailed data about fetal isolated upward rotation of the cerebellar vermis rotation (Blake’s pouch cyst) in particular regarding pregnancy outcome. Methods: This is a retrospective study of all cases of fetal isolated upward rotation of the cerebellar vermis (URCV) diagnosed in 3 referral centers in Italy from January 2009 to November 2019. Whenever possible, prenatal magnetic resonance imaging (MRI) was performed and a fetal karyotype was obtained. A detailed follow-up was obtained by consultation of medical records, interview with the parents, and the pediatricians. Results: Our study population included 111 patients with a prenatal diagnosis of isolated URCV made at a median gestational age of 21 weeks +3 days (interquartile range (IQR) 21 + 0–22 + 2). The median brain stem-vermis (BV) angle was 27° (IQR 24–29°). In 37.9% of the cases, a regression of the finding with restoration of normal anatomy was noted at a follow-up scan or at postnatal checks. A BV angle of 25° or less predicted regression with a probability in excess of 90%. MRI was performed in utero or at birth in 101 patients and always confirmed sonographic diagnosis. Fetal CGH array and/or karyotype was available in 97 cases and was always normal, but in 1 case. A postnatal follow-up was available in 102 infants (mean 7 months, range 0–10 years of age) and documented a normal neurologic development in all the cases. Conclusions: Isolated URCV is most likely a normal variant of fetal anatomy without clinical consequences, at least at an early follow-up. A BV angle of 25° or less predicts intrauterine regression of the finding, but the outcome is good in all the cases. When a confident sonographic diagnosis is made, MRI is not mandatory. The risk of a chromosomal anomaly in these cases is probably low.

Impairment of the immune response and aberrant expression of microRNAs are emerging hallmarks of tumour initiation/progression, in addition to driver gene mutations and epigenetic modifications. We performed a preliminary survey of independent adenoma and colorectal cancer (CRC) miRnoma data sets and, among the most dysregulated miRNAs, we selected miR-27a and disclosed that it is already upregulated in adenoma and further increases during the evolution to adenocarcinoma. To identify novel genes and pathways regulated by this miRNA, we employed a differential 2DE-DIGE proteome analysis. We showed that miR-27a modulates a group of proteins involved in MHC class I cell surface exposure and, mechanistically, demonstrated that calreticulin is a miR-27a direct target responsible for most downstream effects in epistasis experiments. In vitro miR-27a affected cell proliferation and angiogenesis; mouse xenografts of human CRC cell lines expressing different miR-27a levels confirmed the protein variations and recapitulated the cell growth and apoptosis effects. In vivo miR-27a inversely correlated with MHC class I molecules and calreticulin expression, CD8+ T cells infiltration and cytotoxic activity (LAMP-1 exposure and perforin release). Tumours with high miR-27a, low calreticulin and CD8+ T cells' infiltration were associated with distant metastasis and poor prognosis. Our data demonstrate that miR-27a acts as an oncomiRNA, represses MHC class I expression through calreticulin downregulation and affects tumour progression. These results may pave the way for better diagnosis, patient stratification and novel therapeutic approaches.

The study objective was to assess the feasibility and the efficacy of bilateral uterine artery embolization (BUAE) for the treatment of cervical pregnancy. The design was a series of 3 cases of viable cervical pregnancy diagnosed by transvaginal ultrasonography and treated by means of BUAE and subsequent uterine curettage. Three women with viable cervical pregnancy underwent BUAE and subsequent uterine curettage in the department of obstetrics and gynecology, High Risk Pregnancy Center, University "Federico II" of Naples. Measurements included surgical outcomes and preservation of fertility. The treatment was effective in all cases. Two patients resumed normal menstruation about 1 month after the procedure, whereas 1 patient underwent a hysterectomy 2 weeks after embolization because of acute ischemic degeneration of a concomitant myoma. The conservative management of cervical pregnancy with angiographic BUAE is a feasible and effective option, even if subsequent hysterectomy may be required. Counseling is necessary.

Multiple lines of evidence indicate that Wnt/β-catenin signaling plays a fundamental role in colorectal cancer (CRC) initiation and progression. Recent genome-wide data have confirmed that in CRC this pathway is one of the most frequently modified by genetic or epigenetic alterations affecting almost 90% of Wnt/β-catenin gene members. A major challenge is thus learning how the corrupted coordination of this pathway is tied to other signalings to enhance cell growth. Peroxisome proliferator activated receptor γ (PPARγ) is emerging as a growth-limiting and differentiation-promoting factor. In tumorigenesis it exerts a tumor suppressor role and is potentially linked with the Wnt/β-catenin pathway. Based on these results, the identification of new selective PPARγ modulators with inhibitory effects on the Wnt/β-catenin pathway is becoming an interesting perspective. Should, in fact, these molecules display such properties, new research avenues would be opened aimed at developing new molecular targeted drugs. Herein, we review the basic principles and present new hypotheses underlying the crosstalk between Wnt/β-catenin and PPARγ signaling. Furthermore, we discuss the advances in our understanding as to how their altered regulation can culminate in colon cancer and the efforts aimed at designing novel PPARγ agonists endowed with Wnt/β-catenin inhibitory effects to be used as therapeutic and/or preventive agents.
