In order to determine the role of the coupling interval of a premature ventricular contraction (PVC) in the development of paroxysmal ventricular tachycardia (PVT) during the early phase of acute myocardial infarction in man, 52 male patients with documented acute myocardial infarction had 24-hour Holter monitoring commenced within 24 hours of the onset of prolonged chest pain. Review of the ta...

In premature infants without respiratory distress syndrome (RDS), AOP may occur on the first day of life, but it may not present for several days in infants with RDS. Many perinatal and postnatal complications increase the infant’s risk of developing AOP, including central nervous system insult or injury, respiratory insult or injury, metabolic disease, sepsis, congenital defects, inborn errors...

AIM OF THE STUDY Newborns from multiple pregnancies are increasing in number and demonstrate a higher perinatal morbidity and mortality compared to singletons. Prematurity is the main reason for most neonatal diseases in twins, but other variables may play a role and their prenatal evaluation may improve the overall outcome. MAIN FINDINGS Prematurity is six times more frequent in twins and th...

At one time kernicterus was most commonly associated with haemolytic disease of the newborn. With the introduction of adequate exchange transfusions this complication, whether due to Rh or to ABO incompatibility, has been virtually eliminated. In 1950 two groups of workers, Aidin, Corner and Tovey in this country and Zuelzer and Mudgett in America, independently drew attention to the fact that ...

PURPOSE Anemia of prematurity is frequent in preterm infants, for which red blood cell (RBC) transfusion remains the treatment of choice. In this study, we attempted to evaluate the characteristics and risk factors of anemia of prematurity, and suggest ways to reduce anemia and the need for multiple transfusions. MATERIALS AND METHODS Preterm infants weighing less than 1500 g (May 2008-May 20...

PURPOSE To compare infant and retinopathy of prematurity (ROP) characteristics from 3 clinical studies conducted over a 27-year period in the United States. DESIGN Secondary analysis of results of 3 clinical studies. PARTICIPANTS Infants with birth weight (BW) <1251 g. METHODS Analysis of data from the Cryotherapy for Retinopathy of Prematurity (CRYO-ROP) and Early Treatment for Retinopat...

High negative reactivity in early childhood interferes with later academic and behavioral adjustment. Thus, investigating the origins of high negative affectivity in early childhood is of high relevance for understanding emotional morbidity after preterm birth. The present work explored (1) direct prematurity-related consequences for negative reactivity, (2) self-regulatory deficits as a mechan...

PURPOSE To investigate the refractive status and optical components of premature babies with or without retinopathy of prematurity (ROP) at 3-4 years old, and to explore the influence of prematurity and ROP on the refractive status and optical components. METHODS Premature babies receiving fundus examination were recruited into ROP group and non-ROP group, with age-matched full-term babies as...

PURPOSE Fibrovascular contraction and tractional retinal detachment (TRD) are recognized complications associated with the use of anti-vascular endothelial growth factor agents in vasoproliferative vitreoretinopathies. The authors characterize TRDs that developed after intravitreal bevacizumab or ranibizumab therapy for vascularly active retinopathy of prematurity. METHODS This is an internat...

OBJECTIVE To review the literature that addresses the relationship between prematurity, birth weight, and development of language in Brazilian children. SOURCES A systematic review of studies published between 2003 and 2012 in English and Portuguese and indexed in PubMed, LILACS, and SciELO. The following key words were used in the searches: Prematuro, Prematuridade, Linguagem, Prematurity, L...
