We investigate the relationship between maternal exposure to benzene and birth weight outcomes for resident births in the United States in 1996 and 1999, taking advantage of a natural experiment afforded by the regulation of benzene content of gasoline in various American cities. Regression results show that a unit increase (μg/m(3)) in maternal exposure to benzene reduces birth weight by 16.5 ...

introduction: one of the common problems in neonatal period is jaundice that occurs in the first week of birth in 60% of term and 80% of preterm neonates. in preterm newborn hyperbilirubinaemia is higher, persistent, longer, and more likely to be associated with neurological injury than term neonates. the purpose of this study was to determine prophylactic effect of zinc sulphate on hyperbiliru...

INTRODUCTION The current cohort study was conducted to determine the frequency and compare the mortality rate with associated characteristics among low birth weight and normal birth weight infants during the neonatal period at a tertiary healthcare facility, Karachi. METHODOLOGY Close-ended structured questionnaires were used to collect information from the parents of 500 registered neonates ...

objective: to compare the maternal and umbilical cord serum selenium concentrations in low and normal birth weight neonates. materials and methods: a case-control study was carried out in vali-asr and akbarabadi hospitals (jan. to dec. 2013). two groups; case group; 91 mothers who delivered a low birth weight (lbw) neonate and control group; 86 subjects who delivered a normal birth weight neona...

OBJECTIVE The aim of the present study was to compare the beginning of eruption of the first deciduous tooth in preterm infants (<38 weeks) with full-term infants (38 and 42 weeks) of normal birth weight ((3)2.500g), low birth weight (< 2.500g) and very low birth weight (<1.500g), in order to evaluate if premature birth and low birth weight would affect tooth eruption. METHODS The neonatal re...

Background: Intraventricular hemorrhage (IVH) in preterm neonates is a serious problem in neonatal intensive care units (NICU) worldwide. IVH is reported in approximately 60-70% of very-low-birth-weight (VLBW) neonates. The present study aimed to assess the association of IVH with neonatal characteristics and serum markers, such as serum Interleukin-6 (IL-6) level, in preterm neonates in an aca...

OBJECTIVE The present study is a literature review to identify the effects of a very low birth weight newborn on family. This is an important instrument to clarify epidemiological issues and to suggest the directions for health policy efforts. METHOD A three-step review was carried out using databases of journals indexed for Medline/Lilacs/ Scielo/Cochrane published between 1966 and 2005 usin...

background: low birth weight (lbw) is one of the major determinants of neonatal survival as well as postnatal morbidity. objective: the main objective of the present study was to determine neonatal mortality rate (nmr) in lbw infants in yazd, iran. materials and methods: in a prospective-cohort study, all births in the maternity hospitals of yazd, iran in 2004 were evaluated and mortality rate ...

STUDY OBJECTIVE To determine the influence of children born to immigrant mothers on the total proportions of low birth weight and preterm deliveries in Oslo and to explain the increases in the proportions of children with low birth weight and low gestational age since 1980-1982. DESIGN This was a cross sectional study based on Norwegian Medical Birth Registry data and information on mothers' ...
