BACKGROUND Gregg identified the teratogenic effect of maternal rubella infection in 1941 and since then there has been a focus on risk factors for birth defects. In nearly 70% of all birth defects, there is still no known risk factor and close to 30% of all pregnancies end in a foetal loss or spontaneous abortion, often because of a defect in the foetus. A large percentage of the workforce cons...

Almost nothing is known about why pigmented birthmarks (moles or nevi) occur in particular locations of the skin. The causes of most birth defects are also unknown. About 35% of children who claim to remember previous lives have birthmarks and/or birth defects that they (or adult informants) attribute to wounds on a person whose life the child remembers. The cases of 210 such children have been...

BACKGROUND The reasons for increased birth defect prevalence following in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) are largely unknown. Classification of birth defects by pathology rather than organ system, and examination of the role of embryo freezing and thawing may provide clues to the mechanisms involved. This study aimed to investigate these two factors. MET...

BACKGROUND With >1% of US births occurring following use of assisted reproductive technology (ART), it is critical to examine whether ART is associated with birth defects. METHODS We analyzed data from the National Birth Defects Prevention Study, a population-based, multicenter, case-control study of birth defects. We included mothers of fetuses or live-born infants with a major birth defect ...

BACKGROUND Nearly all women shower or take baths during early pregnancy; however, bathing habits (i.e., shower and bath length and frequency) may be related to the risk of maternal hyperthermia and exposure to water disinfection byproducts, both of which are suspected to increase risk for multiple types of birth defects. Thus, we assessed the relationships between bathing habits during pregnanc...

This study examined the effect of prenatal diagnosis and elective termination on the prevalence of neural tube defects, oral clefts, abdominal wall defects, and chromosomal anomalies in Hawaii by using actively ascertained surveillance data collected between 1987 and 1996 by the Hawaii Birth Defects Program. Because the Program has nearly universal access to prenatal diagnostic information and ...

Background Approximately 6.3 million live births and fetal deaths occurred during the ascertainment period in the California Birth Defects Monitoring Program registry. American-Indian and non-Hispanic white women delivered 40,268 and 2,044,118 births, respectively. While much information has been published about non-Hispanic white infants, little is known regarding the risks of birth defects am...

ADVANCES IN HUMAN GENETIC RESEARCH With the relentless progress of the Human Genome Project, by the year 2001, most-if not all-of the estimated 100,000 human genes will have been found (Collins, '98). Close to 10,000 genes have already been cataloged (Online Mendelian Inheritance in Man, '98), and tests for more than 700 genes are already available in medical practice (Pagon, '98). The genes id...
