The present study sought to assess the time trends of spina bifida on the basis of cases identified by the Liaoning Birth Defects Registry in 14 cities from 2006 to 2015. We calculated the prevalence of spina bifida, percent and average change of time trends, and contribution rates of each city. Poisson regression model was used to find the line of best fit for spina bifida prevalence by year, ...

SETTING Canada as a whole and 4 main regions (West, Ontario, Quebec and Atlantic). SUBJECTS All live births from 1930 to 1990. OUTCOME MEASURES Sex ratio (expressed as the proportion of total live birt...

Introduction: Congenital gastrointestinal (GI) malformation occurs due to mal development of GI organs. The diagnosis is based on clinical exam and radiography. The aim of this study was to determine prevalence of gastrointestinal anomalies in Imam Reza hospital deliveries Mashhad, Iran. Materials and Methods: In retrospective descriptive study for one year since 1.8.1391 all deliveries in...

Background: Oral clefts (OCs) are common human birth defects. Children with OCs in underdeveloped regions are more likely to suffer from poverty and hardship in their future lives. Here, we attempted to estimate the prevalence of OCs among live births in Gansu Province in 2008 to understand the epidemiologic pattern of the disease. Methods: A cross-sectional study was conducted from January 200...

“Countries with intermediate levels of mortality should aim to achieve by the year 2005 a maternal mortality rate below 100 per 100,000 live births and by the year 2015 a maternal mortality rate below 60 per 100,000 live births. Countries with the highest levels of mortality should aim to achieve by 2005 a maternal mortality rate below 125 per 100,000 live births and by 2015 a maternal mortalit...

The incidence of neonatal meningitis is difficult to accurately determine because of testing limitations. The incidence of bacterial meningitis is approximately 0.3 per 1000 live births in industrialized countries (Davies & Rudd, 1994). A recent study of neonatal infections in Asia (collecting data from China, Hong Kong, India, Iran, Kuwait, and Thailand), reported estimated incidence of neonat...

During an eight month prospective study, 8240 newborns were examined for detection of congenital dislocation of the hip from Oct. 23, 1991 to June 22, 1992. On fIrst examination we found 1302 neonates (158/1000 live births) to have abnormal hips 1063 (81.6%) were prone to subluxation (subluxatable), 218 (16.81 %) prone to dislocation (dislocatable), 17 (1.3%) were dislocated and 4 (0.3%) w...

METHODS The databases of the Live Birth Information System and the Civil Registry of the Brazilian Institute of Geography and Statistics, from the second and third trimesters of 2006 in Sergipe state (Northeastern Brazil) were paired by deterministic linkage based on the number of the Live Birth Declar...
