Periventricular Leucomalacia

This study presents a rare case of unilateral slipped capital femoral epiphysis treated surgically in a 5-year-old boy with cerebral palsy who was born at 27 weeks' gestation and developed grade III intraventricular haemorrhage and periventricular leucomalacia and was on antiepileptic drugs, including valproic acid and levetiracetam for >3 years. The patient had no history of endocrine, renal, and significant familial diseases.

OBJECTIVE: To explore associations between perinatal activity and survival in infants born at 22 and 23 weeks of gestation in Sweden. DESIGN/SETTING: Data on all births at 22 and 23 weeks' gestational age (GA) were prospectively collected in 2004-2007 (T1) or obtained from national registers in 2014-2016 (T2) and 2017-2019 (T3). Infants were assigned perinatal activity scores based on 3 key obstetric and 4 neonatal interventions. MAIN OUTCOME: One-year survival and survival without major neonatal morbidities (MNM): intraventricular haemorrhage grade 3-4, cystic periventricular leucomalacia, surgical necrotising enterocolitis, retinopathy of prematurity stage 3-5 or severe bronchopulmonary dysplasia...

BACKGROUND: Objective: To identify and examine neural reorganization of the sensory network in terms of lesion type, somatotopic organization of the primary somatosensory area, and functional connectivity in relation to sensory function in children and young adults with cerebral palsy (CP). METHODS: Design: systematic review, Prospero registration ID 342570. Data sources: PubMed; Cochrane; Web of Science; Embase; CINAHL and PEDro from inception to March 13, 2021...

OBJECTIVE: To investigate whether effects of antenatal corticosteroids on neonatal outcomes in preterm infants with very low birth weight were different by plurality. DESIGN: Nationwide prospective cohort study. PATIENTS: Twins and singletons with very low birth weight (<1500 g) who were born between 23+0 and 33+6 weeks of gestation and registered in the Korean Neonatal Network from January 2014 to December 2019. MAIN OUTCOME MEASURES: Morbidity and mortality before discharge from neonatal intensive care unit...

INTRODUCTION: Spastic cerebral palsy (CP) is the commonest physiological type according to literature which comes mainly from the developed countries where prematurity is a common cause for cerebral palsy. In developing countries like India, the leading causes of cerebral palsy are birth asphyxia, infections, and hyperbilirubinemia and, hence, the physiological type of CP is likely to be different. However, the data from our country is scant. METHODS: 103 consecutive treatment-naive CP patients attending pediatric neurology clinic were evaluated in detail using an objective tool, hypertonia assessment tool (HAT) over a period of 6months...

BACKGROUND: Worldwide, nifedipine and atosiban are the two most commonly used tocolytic agents for the treatment of threatened preterm birth. The aim of this study was to evaluate the effectiveness of nifedipine and atosiban in an individual participant data meta-analysis (IPDMA). METHODS: We investigated the occurrence of adverse neonatal outcomes in women with threatened preterm birth by performing an IPDMA, and sought to identify possible subgroups in which one treatment may be preferred...

IMPORTANCE: Animal and observational human studies report that delivery of excessive tidal volume (VT ) at birth is associated with lung and brain injury. Using a respiratory function monitor (RFM) to guide VT delivery might reduce injury and improve outcomes. OBJECTIVE: To determine whether use of an RFM in addition to clinical assessment versus clinical assessment alone during mask ventilation in the delivery room reduces in-hospital mortality and morbidity of infants <37 weeks' gestation...

Advances in neonatal-perinatal medicine have resulted in increased survival at lower gestations. Although the incidence of germinal matrix haemorrhage-intraventricular haemorrhage and cystic periventricular leucomalacia is reducing, a new phenotype of preterm brain injury has emerged consisting of a combination of destructive and dysmaturational effects. Consequently, severe neurological disability is reported at a lower rate than previously, but the overall morbidity associated with premature birth continues to present a large global burden and contributes significantly to increased financial costs to health systems and families...

Periventricular leukomalacia (PVL) is a common magnetic resonance imaging (MRI) finding in cases of hypoxic ischemic encephalopathy. PVL, in MRI, is identified by the increased signal intensity of periventricular white matter on T2-weighted sequences which is more conspicuous in the posterior cortex. It occurs because of perinatal damage to the cerebral cortex. This insult is in the form of hypoxia, metabolic insults, prematurity, seizures, or infection. Periventricular area is most prone to damage owing to its immaturity and vascular supply...

BACKGROUND/AIM: Chronic cerebral hypoperfusion affects early and mature neurons in the subventricular zone (SVZ) and cerebral cortex. Herein, we investigated the effects of insulin-like growth factor-1 (IGF-1), a neurogenesis-promoting agent, on neurons in these regions in periventricular leucomalacia (PVL) model rats. MATERIALS AND METHODS: Following right carotid artery ligation, the rats were placed in a hypoxia chamber and injected with recombinant IGF-1 (0...

OBJECTIVES: South Africa has a double burden of high neonatal mortality and maternal HIV prevalence. Common to both is a proinflammatory in utero and perinatal milieu. The aim of this study was to determine cytokine profiles in HIV exposed (HE) and HIV unexposed (HU) very low birthweight (VLBW) infants and to determine whether these were associated with predischarge outcomes. DESIGN: Single-centre, prospective cohort study conducted from 1 June 2017 to 31 January 2019...

Intra- and periventricular haemorrhage, cystic and diffuse periventricular leucomalacia, post-haemorrhagic ventriculomegali, and cerebral atrophy are "visible" forms of brain injury and explain one third of neurodevelopmental impairment in preterm infants. We have not been successful in proving the benefits of specific preventive measures after birth. The risk of brain injury, however, has decreased over the years, possibly because understanding of the pathophysiology has led to more precisely adapted support of vital functions...

Despite tremendous advances in neonatal intensive care over the past 20 years, prematurity carries a high burden of neurological morbidity lasting lifelong. The term encephalopathy of prematurity (EoP) coined by Volpe in 2009 encompasses all aspects of the now known effects of prematurity on the immature brain, including altered and disturbed development as well as specific lesional hallmarks. Understanding the way cells are damaged is crucial to design brain protective strategies, and in this purpose, preclinical models largely contribute to improve the comprehension of the cell death mechanisms...

BACKGROUND: Cerebral Visual Impairment (CVI) is very common yet often unrecognised visual dysfunction in children with Cerebral Palsy (CP). Magnetic Resonance Imaging (MRI) is the diagnostic tool in the investigation of brain lesions in children with CP and CVI. AIM: The aim of this systematic review is to evaluate the relationship between brain structure and CVI, as determined by MRI in children with CP. METHODS AND PROCEDURES: A comprehensive search of 5 database (PubMed, EMBASE, SCOPUS, CINAHL and Cochrane Database) was undertaken up until June 2019...

OBJECTIVE: To evaluate outcomes of preterm infants <26 weeks gestational age (GA) following postdelivery extensive cardiopulmonary resuscitation (ECPR) compared with airway and breathing support (ABS). STUDY DESIGN: Retrospective review of Canadian Neonatal Network data during January 2010 to December 2016. The primary outcome was death or severe morbidity (intraventricular hemorrhage ≥grade 3 or periventricular leucomalacia, retinopathy of prematurity ≥stage 3, bronchopulmonary dysplasia, or necrotizing enterocolitis)...

OBJECTIVE: To measure prospectively apparent diffusion coefficient (ADC) values between 28 and 32 weeks of gestation in different cerebral territories of fetuses with estimated fetal weight (EFW) ≤ 5th centile, and analyze their association with adverse perinatal outcome. METHODS: This was a prospective study involving six tertiary-level perinatal centers. In the period 22 November 2016 to 11 September 2017, we included singleton, small-for-gestational-age (SGA) fetuses with EFW ≤ 5th percentile, between 28 and 32 weeks of gestation, regardless of the umbilical artery Doppler and maternal uterine artery Doppler findings...

OBJECTIVES: To investigate the effectiveness of routine ultrasonography in the third trimester in reducing adverse perinatal outcomes in low risk pregnancies compared with usual care and the effect of this policy on maternal outcomes and obstetric interventions. DESIGN: Pragmatic, multicentre, stepped wedge cluster randomised trial. SETTING: 60 midwifery practices in the Netherlands. PARTICIPANTS: 13 046 women aged 16 years or older with a low risk singleton pregnancy...

BACKGROUND: The increased potential for negative pregnancy outcomes in both extremes of reproductive age is a well-debated argument. The aim of this study was to analyze the prevalence and the outcome of pregnancies conceived at extreme maternal ages. METHODS: This retrospective study considered all single consecutive pregnancies delivered in a tertiary referral center between 2001 and 2014. Patients were categorized into 4 groups according to maternal age at delivery (< 17 years; 18-28 years; 29-39 years; > 40 years)...

Background : Poor postnatal weight gain has been associated with low serum IGF-1, a key factor in the pathogenesis of retinopathy of prematurity (ROP). Aim : To investigate an association between relative weight gain (RWG) and severe ROP in very low-birthweight (VLBW) Thai infants. Methods : The medical records of VLBW infants who were admitted to the neonatal intensive care unit in Chiang Mai University Hospital from June 2014 to December 2016 and screened for ROP were reviewed. RWG and total calorie intake (TCI) in the 2nd, 4rth and 6th week of age were calculated and those with no ROP/mild ROP and severe ROP requiring laser treatment were compared...

OBJECTIVE: To compare the risk of mortality and morbidity between outborn and propensity score-matched inborn extremely preterm neonates. SETTING: Multiple neonatal intensive care units (NICU) across the USA. PATIENTS: Singleton neonates born at 22-29 weeks' gestation with no major anomalies who were admitted to a NICU and discharged between 2000 and 2014. Outborn neonates were restricted to those who transferred into a NICU on the day of birth...
