Estimation of the reference values and decision limits for growth hormone in newborns using dried blood spots.

OBJECTIVES: Severe deficiency of growth hormone (GHD) of the newborn is a rare but potentially life-threatening disease. GH measured during the first week of life, using dried blood spots (DBS), may offer several advantages. Aim of the study was to estimate the reference values for GH in newborns by a new analytical method using DBS. METHODS: Using a new developed analytical method, GH was estimated from DBS of 1,036 healthy newborns attending the Neonatology Unit of Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico of Milan in the period July-October 2021. Reference values for GH deficiency were estimated by the Harrell-Davis bootstrap method, with 90 %CI calculated by the bias-corrected and accelerated bootstrap method. RESULTS: All GH measurements required 33 analytical sessions (8 months) with a CV% for calibration curve slopes equal to 6.9 %. Intermediate precision evaluated by measurement of low (3 µg/L) and high (10 µg/L) quality controls was, respectively, 14 and 6.5 %. GH reference values, estimated at percentiles 1.0st, 2.5th and 5.0th, and their 90 %CI, were, respectively, 4.5 µg/L (90 %CI 3.8-5.1), 5.9 µg/L (90 %CI 5.4-6.4) and 7.0 µg/L (90 %CI 6.7-7.3). GH levels were not associated with sex, standard deviation scores, birth weight, gestational age, type of delivery or mother's variables (age, smoking habit, gestational diabetes). CONCLUSIONS: Validation data suggest that this method can be used to measured GH in newborns using DBS. The reference values estimated in this study are in accordance with previous published works using ELISA and may help confirming the clinical suspicion of neonatal GHD.

Newborns' perception of approach and withdrawal from biological movement: A closeness story.

Since birth, infants discriminate the biological motion (BM) revealed by point-light displays (PLDs). To date, no studies have explored whether newborns differentiate BM that approaches rather than withdraws from them. Yet, approach and withdrawal are two fundamental motivations in the socio-emotional world, key to developing empathy and prosocial behavior. Through a looking-behavior paradigm, we demonstrated that a few hours after birth, a human figure approaching attracted more visual attention than a human figure receding, showing that newborns are attuned to PLDs of others moving toward rather than walking away from them. Further, a withdrawing body appears to be less attractive than withdrawing scrambled points. Altogether, these observations support the existence of an early predisposition toward social closeness that might have its roots in an evolutionary perspective.

Application of a portable instrument for rapid and reliable detection of SARS-CoV-2 infection in any environment.

The ongoing outbreak of the novel coronavirus (SARS-CoV-2) infection is creating serious challenges for health laboratories that seek to identify viral infections as early as possible, optimally at the earliest appearance of symptom. Indeed, there is urgent need to develop and deploy robust diagnostic methodologies not only to use in health laboratory environments but also directly in places where humans circulate and spread the virus such as airports, trains, boats, and any public aggregation places. The success of a reliable and sensitive asymptomatic diagnosis relies on the identification and measurement of informative biomarkers from human host and virus in a rapid, sensitive, and inexpensive manner. The objective of this article is to describe an innovative multidisciplinary approach to develop an efficient, inexpensive, and easy-to-use portable instrument (bCUBE® by Hyris Ltd) that can be employed as a surveillance system for the emergency caused by SARS-CoV-2. A solution for Coronavirus testing, compliant with CDC guidelines, is scheduled to be released in the next weeks. In addition, we will describe a workflow and path of an integrated multi-omic approach that will lead to host and pathogen biomarker discovery in order to train the instrument to provide reliable results based on a specific biomarker's fingerprint of SARS-CoV-2 infection.

Spontaneous Coronary Artery Dissection in Clinical Practice: Pathophysiology and Therapeutic Approaches.

Spontaneous coronary artery dissection (SCAD) is a cause of myocardial infarction without obstructive coronary artery disease (MINOCA). It is determined by a coronary artery wall layers separation, which occurs regardless of traumatic or iatrogenic injuries. Even if it is often a missed diagnosis, its incidence is growing along with the improvement of intracoronary imaging techniques that allow for better detection. The main angiographical classification distinguishes three different forms, with slightly different prognoses at long-term follow up. SCAD is a recurrent condition, severely hampering the life quality of affected patients. The predominantly young age of patients with SCAD and the high prevalence of females among them have made the topic increasingly important, especially regarding therapeutic strategies. According to the data, the most recommended treatment is conservative, based on the use of antiplatelet agents and supportive anti-ischemic therapy. However, there are conflicting opinions concerning the need for dual antiplatelet therapy and its duration. In the case of invasive treatment, the choice between percutaneous coronary intervention and coronary artery bypass graft depends on the patient's clinical stability and the interested vessel. The purpose of the current review is to revise the pathophysiological mechanisms underlying SCAD and the current knowledge of its treatment.

Epstein-Barr virus and malaria upregulate AID and APOBEC3 enzymes, but only AID seems to play a major mutagenic role in Burkitt lymphoma.

Endemic Burkitt lymphoma (eBL) is characterized by an oncogenic IGH/c-MYC translocation and Epstein-Barr virus (EBV) positivity, and is epidemiologically linked to Plasmodium falciparum malaria. Both EBV and malaria are thought to contribute to eBL by inducing the expression of activation-induced cytidine deaminase (AID), an enzyme involved in the IGH/c-MYC translocation. AID/apolipoprotein B mRNA editing catalytic polypeptide-like (AID/APOBEC) family enzymes have recently emerged as potent mutagenic sources in a variety of cancers, but apart from AID, their involvement in eBL and their regulation by EBV and P. falciparum is unknown. Here, we show that upon inoculation with EBV, human B cells strongly upregulate the expression of enzymatically active APOBEC3B and APOBEC3G. In addition, we found significantly increased levels of APOBEC3A in B cells of malaria patients, which correlated with parasite load. Interestingly, despite the fact that APOBEC3A, APOBEC3B, and APOBEC3G caused c-MYC mutations when overexpressed in HEK293T cells, a mutational enrichment in eBL tumors was only detected in AID motifs. This suggests that even though the EBV- and P. falciparum-directed immune response triggers the expression and activity of several AID/APOBEC members, only the upregulation of AID has oncogenic consequences, while the induction of the APOBEC3 subfamily may primarily have immunoprotective functions.

Congenital diaphragmatic hernia in Coffin Siris syndrome: Further evidence from two cases.

Coffin-Siris Syndrome (CSS) is a rare multi-system dominant condition with a variable clinical presentation mainly characterized by hypoplasia/aplasia of the nail and/or distal phalanx of the fifth digit, coarse facies, hirsutism/hypertrichosis, developmental delay and intellectual disability of variable degree and growth impairment. Congenital anomalies may include cardiac, genitourinary and central nervous system malformations whereas congenital diaphragmatic hernia (CDH) is rarely reported. The genes usually involved in CSS pathogenesis are ARID1B (most frequently), SMARCA4, SMARCB1, ARID1A, SMARCE1, DPF2, and PHF6. Here, we present two cases of CSS presenting with CDH, for whom Whole Exome Sequencing (WES) identified two distinct de novo heterozygous causative variants, one in ARID1B (case 1) and one in SMARCA4 (case 2). Due to the rarity of CDH in CSS, in both cases the occurrence of CDH did not represent a predictive sign of CSS but, on the other hand, prompted genetic testing before (case 1) or independently (case 2) from the clinical hypothesis of CSS. We provide further evidence of the association between CSS and CDH, reviewed previous cases from literature and discuss possible functional links to related conditions.

Newborns' early attuning to hand-to-mouth coordinated actions.

Already inside the womb, fetuses frequently bring their hands to the mouth, anticipating hand-to-mouth contact by opening the mouth. Here, we explored whether 2-day-old newborns discriminate between hand actions directed towards different targets of the face-that is, a thumb that reaches the mouth and a thumb that reaches the chin. Newborns looked longer towards the thumb-to-mouth compared to the thumb-to-chin action only in the presence, and not absence, of anticipatory mouth opening movements, preceding the thumb arrival. Overall, our results show that newborns are sensitive to hand-to-face coordinated actions, being capable to discriminate between body-related actions directed towards different targets of the face, but only when a salient visual cue that anticipates the target of the action is present. The role of newborns' sensorimotor experience with hand-to-mouth gestures in driving this capacity is discussed.

The hidden universe of human milk microbiome: origin, composition, determinants, role, and future perspectives.

Although traditionally considered sterile, human milk is currently recognized as an alive ecosystem that harbors not only bacteria, but also viruses, fungi and yeasts, and minor genera, collectively known as the human milk microbiome (HMM). The seeding of HMM is a complex phenomenon whose dynamics are still a matter of research. Many factors contribute to its determination, both maternal, neonatal, environmental, and related to human milk itself. The transmission of microorganisms to the infant through breastfeeding may impact its present and future health, mainly shaping the GI tract microbiome and immune system. The existence and persistence of HMM as a conserved feature among different species may also have an evolutionary meaning, which will become apparent only in evolutionary times. CONCLUSION: The complexities of HMM warrant further research in order to deepen our knowledge on its origin, determinants, and impact on infants' health. The practical and translational implications of research on HMM (e.g., reconstitution of donor human milk through inoculation of infant's own mother milk, modulation of HMM through maternal dietary supplementation) should not be overlooked. WHAT IS KNOWN: • Human milk harbors a wide variety of microorganisms, ranging from bacteria to viruses, fungi and yeasts, and minor genera. • Human milk microbiome is shaped over time by many factors: maternal, neonatal, environmental, and related to human milk itself. • The transmission of microorganisms through breastfeeding may impact the infant's present and future health. WHAT IS NEW: • We provide an overview on human milk microbiome, hopefully encouraging physicians to consider it among the other better-known breastfeeding benefits. • Further studies, with standardized and rigorous study designs to enhance accuracy and reproducibility of the results, are needed to deepen our knowledge of the human milk microbiota and its role in newborn and infant's health.

Achillea moschata Wulfen: From Ethnobotany to Phytochemistry, Morphology, and Biological Activity.

A multidisciplinary investigation on Achillea moschata Wulfen (Asteraceae) is outlined herein. This work, part of the European Interreg Italy-Switzerland B-ICE project, originated from an ethnobotanical survey performed in Chiesa in Valmalenco (Sondrio, Lombardy, Northern Italy) in 2019-2021 which highlighted this species' relevance of use in folk medicine to treat gastrointestinal diseases. In addition, this contribution included analyses of the: (a) phytochemical profile of the aqueous and methanolic extracts of the dried flower heads using LC-MS/MS; (b) morpho-anatomy and histochemistry of the vegetative and reproductive organs through Light, Fluorescence, and Scanning Electron Microscopy; (c) biological activity of the aqueous extract concerning the antioxidant and anti-inflammatory potential through cell-based in vitro models. A total of 31 compounds (5 phenolic acids, 13 flavonols, and 13 flavones) were detected, 28 of which included in both extracts. Covering and secreting trichomes were observed: the biseriate 10-celled glandular trichomes prevailing on the inflorescences represented the main sites of synthesis of the polyphenols and flavonoids detected in the extracts, along with volatile terpenoids. Finally, significant antioxidant and anti-inflammatory activities of the aqueous extract were documented, even at very low concentrations; for the first time, the in vitro tests allowed us to formulate hypotheses about the mechanism of action. This work brings an element of novelty due to the faithful reproduction of the traditional aqueous preparation and the combination of phytochemical and micromorphological research approaches.

From dyad to triad: a survey on fathers' knowledge and attitudes toward breastfeeding.

Fathers are known to impact breastfeeding outcomes. We aimed to explore paternal knowledge and attitude toward breastfeeding, and possible association with breastfeeding rates at discharge. In this cross-sectional study, we enrolled 200 fathers of healthy term neonates. At discharge, fathers were asked to rate their degree of agreement to 12 items on a 5-point Likert scale. A total score was obtained from their answers. Univariate binary logistic regression analysis was used to verify if the total score was predictive of exclusive breastfeeding at discharge. A multivariable logistic regression model was then used to adjust for possible confounders. ROC analysis was performed, and a Youden's total score cut-off value was determined to define total score's performance in predicting exclusive breastfeeding at discharge. Fathers showed a solid knowledge of maternal (87%) and neonatal (98%) benefits of breastfeeding, skin-to-skin (99.5%), rooming-in (79%), and responsive feeding (67.5%); conversely, only 51% knew about the recommended use of pacifiers. Fathers felt personally involved in babies' feeding in 79% of cases. An association was found between total score and exclusive breastfeeding at discharge at univariate (OR: 1.07, p = 0.04) but not at multivariable analysis (OR: 1.07, p = 0.067). ROC analysis was not statistically significant (AUC 0.58, p = 0.083).Conclusion: By using a novel instrument aimed at quantifying fathers' knowledge and overall attitude toward breastfeeding, this study underlines the importance of including fathers in the promotion of breastfeeding. Expanding the classic mother-baby dyad to a more modern mother-father-baby triad may impact breastfeeding outcomes at discharge. What is known: • Social support plays a major role in improving breastfeeding outcomes. • Fathers may greatly influence initiation and duration of breastfeeding; the more they know, the more helpful they can be. What is new: • A multidisciplinary team created a structured questionnaire aimed at quantifying fathers' knowledge and attitude toward breastfeeding. • The association between a higher questionnaire total score and exclusive breastfeeding rates at discharge highlights the importance of including fathers in the promotion of breastfeeding, as part of the breastfeeding team.

Heart-rate agreement between ECG and a new, wireless device during early skin-to-skin contact.

AIM: To assess the agreement of heart rate (HR) between the new device - a fabric jacket for neonates, with integrated sensors detecting ECG signals and a Bluetooth connection to a computer (ComfTech, HOWDY) - and the clinical reference, ECG, during the skin-to-skin contact (SSC) in the first 2 h after birth, for the potential use of early detection of Sudden and Unexpected Postnatal Collapse (SUPC). METHODS: We enrolled newborns ≥35+0  weeks of gestation, with Apgar score >8 at 5 min in a prospective, observational study in the delivery room, excluding infants with need for resuscitation, clinical instability or major malformations. We assessed HR within 20 min after birth by both devices simultaneously: the index test ComfTech HOWDY and the standard ECG (Vita Guard VG 3100, Getemed). We compared HR between the two methods at 0, 15, 30, 45, 60, 90 and 120 min by the Bland-Altman plot. RESULTS: We included 60 infants. The mean difference between the methods was -1.3 bpm, 95%LoA -12.4 to 9.7 bpm. Spearman rank correlation coefficient ρ = -0.06. CONCLUSION: ComfTech HOWDY presents reliable agreement with the ECG and might assist in identifying infants at risk for SUPC.

Knowledge and attitude of health staff towards breastfeeding in NICU setting: are we there yet? An Italian survey.

The benefits of human milk in preterm infants, a population at high risk for developing adverse outcomes for which breast milk is a protective factor, are widely acknowledged. However, preterms' admission in a neonatal intensive care unit (NICU) and newborn's clinical conditions have been described as significant barriers, leading to lower rates of breastfeeding initiation and duration. Healthcare workers play a crucial role in encouraging breastfeeding. We conducted a cross-sectional survey among nurses working in six Italian NICUs, exploring their knowledge and attitude towards breastfeeding. Although the majority of nurses had a specific breastfeeding education, our results show still some variations among answers regarding aspects of breastfeeding support in this setting. Specifically, family-centered care, transition feeding to the breast, and skin-to-skin practice, despite being extensively addressed by the Neo Baby-Friendly Hospital Initiative, are the items that highlighted a range of answers that could result in conflicting information to mothers.Conclusion: By underlining the gaps of knowledge and attitude towards breastfeeding of nurses working in NICUs, this study provides an insight into what needs to be improved, with the aim of promoting higher rates of breastfeeding in the preterm population. What is Known: • Breastfeeding is particularly challenging in the preterm population, despite its universally recognized health benefits. • Improving healthcare professionals' knowledge and attitude towards breastfeeding has been shown to be crucial for promoting breastfeeding in NICUs. What is New: • Our results provide useful insight into nurses' knowledge and attitude towards breastfeeding in NICU settings. • By acknowledging strengths and weaknesses highlighted by this study, tailored strategies could be developed to improve health staff breastfeeding education and support to parents in NICU settings.

Using Medicinal Plants in Valmalenco (Italian Alps): From Tradition to Scientific Approaches.

This ethnobotanical survey was carried out in Caspoggio (Valmalenco, SO, Italy) with the purpose of investigating the traditional uses of medicinal plants. Moreover, a bibliographic research meant to validate or refute the uses, focusing on the potentially responsible compounds, was performed. Fifty-nine species, attributable to 30 families (Asteraceae, Pinaceae, Malvaceae, and Lamiaceae the most cited), were mentioned. Arnica montana, anti-inflammatory for traumas and musculoskeletal pains; Pinus mugo, expectorant; Malva sylvestris, anti-inflammatory and soothing; Achillea moschata, digestive. The compounds, responsible for the therapeutic activities, are often polyphenols and terpenoids: helenanin in A. montana, α-pinene, δ-3-carene, and limonene in P. mugo, gossypin and malvin in M. sylvestris, luteolin and apigenin in A. moschata. Scientific evidence for at least one of the traditional activities described was found for 50 species but only in 26 out of 196 works consulted, it is possible to make a comparison between investigated extracts and traditional preparations. This study is thus a stimulus to new phytochemical investigations, mimicking as much as possible the traditional preparations. This work is part of the European Interreg Italy-Switzerland B-ICE project, aimed at creating a management model for the ongoing climate change and searching for new sources of territory valorization as attractions for tourists.

High purity high yield tandem B and T helper cell isolation for qRT-PCR analysis suitable for basically equipped laboratories.

BACKGROUND: Malaria is still a major health problem in sub-Saharan Africa and south-east Asia, but research on malaria in low-income countries can be a challenge due to the lack of laboratory equipment. In addition, severe malaria mainly affects very young children, which limits the amount of blood available for research purposes. Thus, there is a need for protocols that yield a maximum of information from a minimum amount of blood, which are operable in basically equipped laboratories. RESULTS: A protocol for tandem B and T helper (Th) cell isolation directly from whole blood, and a freezer-independent sample preservation method compatible with the warm and humid climate of malaria regions was established and validated. The protocol thereby circumvents the need of high-technology centrifuges and unimpeachable power supply for peripheral blood mononuclear cell isolation. Both purity and yield are excellent. Depending on the expression level of the genes of interest, between 2 and 5 ml of blood are adequate for reliable qRT-PCR results from both B and Th cells of healthy paediatric donors as well as paediatric malaria patients. CONCLUSION: This protocol for high purity high yield B cell and Th cell isolation and sample storage for subsequent qRT-PCR analysis from a minimal amount of blood is contrivable with basic equipment and independent of continuous power supply. Thus, it is likely to be of avail for many scientists performing malaria research in rural institutes or hospitals, and thus in countries where malaria is most prevalent.

Serum creatinine during physiological perinatal dehydration may estimate individual nephron endowment.

It is well known that the nephron endowment of healthy subjects is highly variable and that individual nephron mass has potentially important implications both in health and disease. However, nephron count is technically impossible in living subjects. Based on the observation of an increase in serum creatinine (sCr) in otherwise healthy newborns with solitary kidney during the physiological perinatal dehydration, we hypothesized that perinatal sCr might be helpful in identifying healthy subjects with a reduced nephron mass. In the framework of a study on blood pressure in babies (NeoNeph), sCr of normal Caucasian neonates was determined 48-96 h after birth and their association with a family history of arterial hypertension (AH) was analyzed. SCr was determined in 182 normal newborns (90 males) at a mean of 61 ± 8 h after birth (range 46-82). Newborns with paternal AH had a higher mean sCr (0.97 + 0.28 mg/dL) then newborns without paternal AH (0.73 + 0.28 mg/dL; p = 0.006). No differences in mean sCr were found in relation with mother or grandparent's history of AH. CONCLUSION: The association between parental AH and high sCr during perinatal dehydration supports the hypothesis that the latter is a promising tool for identifying normal subjects with a reduced nephron mass with potential important implications in prevention and in understanding the individual outcome of renal and extrarenal diseases (including AH). What is Known: • Nephron endowment of healthy subjects is highly variable and individual nephron mass has potentially important implications both in health and disease however nephron count is not feasible in living subjects. What is New: • Serum creatinine during perinatal dehydration is a possible biomarker for identifying normal subjects with a reduced nephron mass.

Sequence variants identification at the KCNQ1OT1:TSS differentially Methylated region in isolated omphalocele cases.

BACKGROUND: Omphalocele is a congenital midline ventral body wall defect that can exist as isolated malformation or as part of a syndrome. It can be considered one of the major and most frequent clinical manifestation of Beckwith-Wiedemann Syndrome (BWS) in case of loss of methylation at KCNQ1OT1: Transcription Star Site-Differentially Methylated Region (TSS-DMR) or in presence of CDKN1C mutations. The isolated form of the omphalocele accounts approximately for about the 14% of the total cases and its molecular etiology has never been fully elucidated. METHODS: Given the tight relationship with BWS, we hypothesized that the isolated form of the omphalocele could belong to the heterogeneous spectrum of the BWS associated features, representing an endophenotype with a clear genetic connection. We therefore investigated genetic and epigenetic changes affecting BWS imprinted locus at 11p15.5 imprinted region, focusing in particular on the KCNQ1OT1:TSS DMR. RESULTS: We studied 21 cases of isolated omphalocele detected during pregnancy or at birth and identified the following rare maternally inherited variants: i) the non-coding variant G > A at nucleotide 687 (NR_002728.3) at KCNQ1OT1:TSS-DMR, which alters the methylation pattern of the imprinted allele, in one patient; ii) the deletion c.624-629delGGCCCC at exon 1 of CDKN1C, with unknown clinical significance, in two unrelated cases. CONCLUSIONS: Taken together, these findings suggest that KCNQ1OT1:TSS-DMR could be a susceptibility locus for the isolated omphalocele.

STAR syndrome plus: The first description of a female patient with the lethal form.

The STAR syndrome is a rare X-linked dominant developmental disorder caused by point mutations in the single FAM58A gene or deletions involving FAM58A and its flanking genes. The STAR phenotype is characterized by a rather homogeneous constellation of facial dysmorphisms and malformations summarized by its acronym, Syndactyly, Telecanthus, Anogenital, and Renal malformations. Here we describe a female patient with STAR syndrome and a 130 kb deletion at Xq28, including the FAM58A gene. She presented with cleft lip palate, omphalocele, and cerebral malformations not previously considered part of the phenotypic spectrum of this syndrome. She died at 6 weeks from respiratory failure.

Intracrine sex steroid synthesis and signaling in human epidermal keratinocytes and dermal fibroblasts.

Peripheral intracrine sex steroid synthesis from adrenal precursors dehydroepiandrosterone (DHEA) and DHEA-sulfate has evolved in humans. We sought to establish if there are differences in intracrine, paracrine, and endocrine regulation of sex steroids by primary cultures of human skin epidermal keratinocytes and dermal fibroblasts. Microarray analysis identified multifunctional genes modulated by steroids, quantitative RT-PCR (qRT-PCR) mRNA expression, enzymatic assay aromatase activity, scratch assay cell migration, immunocytochemistry α-smooth muscle actin (α-SMA), and collagen gel fibroblast contraction. All steroidogenic components were present, although only keratinocytes expressed the organic anion organic anion transporter protein (OATP) 2B1 transporter. Both expressed the G-protein-coupled estrogen receptor (GPER1). Steroids modulated multifunctional genes, up-regulating genes important in repair and aging [angiopoietin-like 4 (ANGPTL4), chemokine (C-X-C motif) ligand 1 (CXCL1), lamin B1 (LMNB1), and thioredoxin interacting protein (TXNIP)]. DHEA-sulfate (DHEA-S), DHEA, and 17ß-estradiol stimulated keratinocyte and fibroblast migration at early (4 h) and late (24-48 h) time points, suggesting involvement of genomic and nongenomic signaling. Migration was blocked by aromatase and steroid sulfatase (STS) inhibitors confirming intracrine synthesis to estrogen. Testosterone had little effect, implying it is not an intermediate. Steroids stimulated fibroblast contraction but not α-SMA expression. Mechanical wounding reduced fibroblast aromatase activity but increased keratinocyte activity, amplifying the bioavailability of intracellular estrogen. Cultured fibroblasts and keratinocytes provide a biologically relevant model system to investigate the complex pathways of sex steroid intracrinology in human skin.

Prenatal ultrasound factors and genetic disorders in pregnancies complicated by polyhydramnios.

OBJECTIVE: The objective of the study is to examine the incidence of chromosomal or genetic abnormalities in pregnancies complicated by polyhydramnios and to assess the value of prenatal ultrasound findings in the prediction of cases associated with such disorders. METHODS: We searched the prenatal records of all patients delivered in our hospital with a diagnosis of polyhydramnios during pregnancy. For each case, maternal characteristics, ultrasound findings, and genetic testing results were recorded. A postnatal follow-up program of at least 6 months, including a clinical assessment by a clinical geneticist, was carried out in all cases. RESULTS: On a total of 195 cases, genetic testing and clinical examination identified a chromosomal or genetic disease in 26 (13.3%) cases. Multivariate analysis demonstrated that significant predictors of a genetic disorder were a deepest vertical pocket of amniotic fluid of ≥13.0 cm (OR 4.306, 95%CI: 1.535-12.079) and reduced fetal movements (OR 25.084, 95%CI: 4.577-137.461), but not the presence of a structural defect. CONCLUSION: A postnatal clinical follow-up program can reveal chromosomal or genetic disorders in about 13% of neonates with a prenatal diagnosis of polyhydramnios. The severity of polyhydramnios and the reduction of fetal movements are independently associated with the presence of such diseases. © 2016 John Wiley & Sons, Ltd.

Unusual prenatal presentation of Rubinstein-Taybi syndrome: a case report.

Rubinstein-Taybi syndrome (RTS) is a rare multiple congenital anomalies-intellectual disability syndrome. The diagnosis is made after birth and based on the detection of signs such as growth and developmental delay, minor facial anomalies, and broad thumbs and halluces. It is rare to suspect RTS during the prenatal period. We report here the approach to a patient with RTS whose pregnancy was complicated by multiple congenital anomalies. However, in the presence of the broad thumb and facial anomalies, we were able to suggest the correct diagnosis. The RTS was confirmed at birth and the molecular analysis of the major causative gene revealed a previously unreported heterozygous truncating mutation of CREBBP. This report provides new knowledge of the fetal phenotype of RTS.
