Maternal exposure to tobacco and alcohol is a known cause, among others, for fetal growth restriction (FGR). Clinically, FGR can be subclassified into two forms: intrauterine growth restriction (IUGR) and small for gestational age (SGA), based on the severity of the growth retardation, and abnormal uterine artery Doppler or cerebro-placental ratio. This study aimed at investigating any differential correlation between maternal exposures to these toxins with the two clinical forms of FGR. Therefore, a case-control study was conducted in Barcelona, Spain...

Thyroid hormones are vital for the proper functioning of the female reproductive system, since they modulate the metabolism and development of ovarian, uterine and placental tissues. Therefore, hypo- and hyperthyroidism may result in subfertility or infertility in both women and animals. Other well-documented sequelae of maternal thyroid dysfunctions include menstrual/estral irregularity, anovulation, abortion, preterm delivery, preeclampsia, intrauterine growth restriction, postpartum thyroiditis, and mental retardation in children...

Prenatal exposure to tobacco smoke is a significant risk-factor for airway disease development. Furthermore, the high prevalence of pregnant smoking women requires the establishment of strategies for offspring lung protection. Therefore, we here aimed to understand the molecular mechanism of how prenatal smoke exposure affects fetal lung development. We used a mouse model recapitulating clinical findings of prenatally exposed children, where pregnant mice were exposed to smoke until c-section or spontaneous delivery, and offspring weight development and lung function was monitored...

Exposure of pregnant women to fine particulate matter<2.5μm in diameter (PM2.5 ) is responsible for low birthweight (LBW) and intellectual disabilities, as expressed by a lower intelligence quotient (IQ). We estimated the attributable cost due to PM2.5 of healthcare at birth and cognitive retardation of children with LBW in metropolitan France in 2012. The cost of specific care of the 8300 (range, 3100-13,300) children born every year in France with a LBW attributable to PM2.5 exposure is estimated at €25 million (range, € 9...

Recent advances in epigenetics have made a tremendous impact on our knowledge of biological phenomena and the environmental stressors on complex diseases. Understanding the mechanism of epigenetic reprogramming during the occurrence of pulmonary hypertension (PH) is important for advanced studies and clinical therapy. In this article, we review the discovery of novel epigenetic mechanisms associated with PH including DNA methylation, histone modification, and noncoding RNA interference. In addition, we highlight the role of epigenetic mechanisms in adult PAH resulting from undesirable perinatal environments-Extrauterine growth restriction (EUGR) and Intrauterine growth retardation (IUGR)...

Short stature, which is defined as height below 2 standard deviations of the mean height for the age and sex, is one of the most frequent reasons for medical consultations in children. Short stature may occur due to a constitutional delay in growth, familial short stature or chronic diseases, including many genetic syndromes, metabolic and endocrine disorders. In this article the authors provide a mini-review of the most frequent genetic syndromes associated with short stature that should be taken into account in the differential diagnosis process...

Prenatal hypoxia causes intrauterine growth retardation. It is unclear whether/how hypoxia affects the bone in fetal and offspring life. This study showed that prenatal hypoxia retarded fetal skeletal growth in rats, inhibited extracellular matrix (ECM) synthesis and down-regulated of insulin-like growth factor 1 (IGF1) signaling in fetal growth plate chondrocytes in vivo and in vitro. In addition, ovariectomized (OVX) was used for study of postmenopausal osteoporosis. Compared with the control, OVX offspring in prenatal hypoxic group showed an enhanced osteoporosis in the femurs, associated with reduced proteoglycan and IGF1 signaling...

Autophagy plays a vital role in embryonic development and cell differentiation. Our previous study demonstrated that prenatal ethanol exposure (PEE) resulted in intrauterine growth retardation (IUGR) and adrenal developmental toxicities in rat offspring. The present study focused on PEE-induced autophagy as an underlying mechanism and its biological significance in female fetal rats. Female fetuses in the PEE group exhibited lower body weights and suffered adrenal structural abnormalities compared to the controls...

With fewer than 200 reported cases, Cushing's syndrome (CS) in pregnancy remains a diagnostic and therapeutic challenge. In normal pregnancies, misleading signs may be observed such as striae or hypokalemia, while plasma cortisol and urinary free cortisol may rise up to 2- to 3-fold. While the dexamethasone suppression test is difficult to use, reference values for salivary cortisol appear valid. Apart from gestational hypertension, differential diagnosis includes pheochromocytoma and primary aldosteronism...

BACKGROUND: Since 2010, array-CGH (aCGH) has been the first-tier test in the diagnostic approach of children with neurodevelopmental disorders (NDD) or multiple congenital anomalies (MCA) of unknown origin. Its broad application led to the detection of numerous variants of uncertain clinical significance (VOUS). How to appropriately interpret aCGH results represents a challenge for the clinician. METHOD: We present a retrospective study on 293 patients with age range 1 month - 29 years (median 7 years) with NDD and/or MCA and/or dysmorphisms, investigated through aCGH between 2005 and 2016...
