BACKGROUND: Pregnant women at high risk of preterm delivery receive glucocorticoids to accelerate fetal lung maturation and surfactant synthesis. However, the effect of antenatal steroids on the developing diaphragm remains unclear. We hypothesized that maternal betamethasone impairs the fetal diaphragm, and the magnitude of the detrimental effect increases with longer duration of exposure. We aimed to determine how different durations of fetal exposure to maternal betamethasone treatment influence the fetal diaphragm at the functional and molecular levels...

Haemangiomas are most common non-malignant vascular tumours of infancy. Here, we describe an antenatally detected mass over the neck causing compressive respiratory compromise at birth requiring resuscitative measures at birth. The mass showed increased vascularity on Contrast Enhanced Computed Tomography (CECT) with extension upto superior mediastinum. Surgical excision was required following failure to medical measures with steroids and propranolol. Histopathology confirmed it to be a venous haemangioma. This case highlights that these benign lesions may reach large sizes and antenatal detection may help in planning effective delivery and resuscitative measures...

BACKGROUND: To examine variation in quality report viewing and assess correlation between provider report viewing and neonatal intensive care unit (NICU) quality. METHODS: Variation in report viewing sessions for 129 California Perinatal Quality Care Collaborative NICUs was examined. NICUs were stratified into tertiles based on their antenatal steroid (ANS) use and hospital-acquired infection (HAI) rates to compare report viewing session counts. RESULTS: The number of report viewing sessions initiated by providers varied widely over a 2-year period (median=11; mean=25...

PURPOSE OF REVIEW: Bronchopulmonary dysplasia (BPD) or chronic lung disease of infancy BPD was originally described 50 years ago, in 1967 by Northway et al. This article possesses two fundamental objectives to provide: a brief historical perspective on BPD; and an update relative to current notions of epidemiology, pathophysiology, evaluation, and clinical management of BPD complicated by vascular disease. The review highlights areas of consensus and ongoing uncertainty. RECENT FINDINGS: The clinical cause and presentation of infants with BPD has evolved over the past several decades...

Developmental programming studies indicate that glucocorticoids modify fetal development. We hypothesized that administration of the synthetic glucocorticoid (sGC) betamethasone to pregnant baboons at doses and stages of fetal life equivalent to human obstetric practice to decrease premature offspring morbidity and mortality, programs lipid metabolism. In 10-year-old male baboons (human equivalent 40) exposed in fetal life to betamethasone or saline, we quantified pericardial fat and hepatic lipid content with magnetic resonance imaging and spectroscopy...

BACKGROUND: Respiratory morbidity including respiratory distress syndrome (RDS) is a serious complication of preterm birth and the primary cause of early neonatal mortality and disability. While researching the effects of the steroid dexamethasone on premature parturition in fetal sheep in 1969, Liggins found that there was some inflation of the lungs of lambs born at gestations at which the lungs would be expected to be airless. Liggins and Howie published the first randomised controlled trial in humans in 1972 and many others followed...

Antenatal corticosteroids have been shown consistently to improve respiratory and other outcomes for infants born preterm (Roberts D et al. Cochrane database of systematic reviews. 2006(3):CD004454). Since Liggins and Howie we know that timing of corticosteroid administration influences the likelihood of benefit (Liggins GC et al. Pediatrics. 1972;50(4):515-525; Ring AM et al. Am J Obstet Gynecol. 2007;196(5):457 e451-456). In fact, the lack of benefit after seven days in their trial led to numerous studies evaluating serial administration of steroids...

BACKGROUND: While there are good data to describe changing trends in mortality and morbidity rates for preterm populations, there is very little information on the specific causes and pattern of death in terms of age of vulnerability. It is well established that mortality increases with decreasing gestational age but there are limited data on the specific causes that account for this increased mortality. The aim of this study was to establish the common causes of hospital mortality in a regional preterm population admitted to a neonatal intensive care unit (NICU)...

In the pathogenesis of neonatal intraventricular hemorrhage (IVH) in preterm infants, an important role is played by changes in venous and arterial cerebral flows. It has been shown that the ability of autoregulation of cerebral flows in response to variations in arterial blood pressure in preterm infants is impaired. This impaired autoregulation causes an increased risk of germinal matrix rupture and IVH occurrence. We examined three polymorphisms of genes, related to regulation of blood flow, for an association with IVH in 100 preterm infants born from singleton pregnancy, before 32 + 0 weeks of gestation, exposed to antenatal steroids therapy, and without congenital abnormalities...

BACKGROUND: Postnatal adaptation requires liquid clearance and lung aeration. However, their relative contribution to the expansion of functional residual capacity (FRC) has not been fully investigated. We studied evolution of lung liquid removal and lung aeration after birth in preterm lambs. METHODS: Lung liquid content and lung volume were assessed at birth and every 30 minutes over 2 hours using MRI in 3 groups of lambs delivered by cesarean: preterm, late preterm, and late preterm with antenatal steroids...

AIMS: The use of antenatal glucocorticoids in women with preterm labor has dramatically improved outcomes for premature infants. The most commonly used antenatal glucocorticoids are betamethasone and dexamethasone. Glucocorticoids accelerate fetal lung growth by several mechanisms, including the maturation of type II pneumocytes enabling surfactant production. Furthermore, the lipids in the lung share similarity with those in the skin. Therefore, antenatal administration of glucocorticoids may have effects on the structure and function of the developing epidermal barrier in fetuses and neonates...
