Fever during pregnancy, especially during embryogenesis, has also been associated with congenital malformations in human offspring. The purpose of this large cohort study of clinically recognized pregnancies was to investigate whether fever during first trimester was associated with an increased risk of congenital malformations in the offspring. The mother’s consumption of alcohol during pregnancy can cause a continuum of various permanent birth defects: cranofacial abnormalities, brain damage, intellectual disability, heart disease, kidney abnormality, skeletal anomalies, ocular abnormalities. The prevalence of children affected is estimated at least 1% in U.S. as well in Canada.

Very few studies have investigated the links between paternal alcohol use and offspring health. Congenital anomalies of the kidney and urinary tract (CAKUT) also encompass a spectrum of abnormalities in renal parenchymal development, renal migration, and the developing collecting system. Most of these anomalies are diagnosed in the antenatal or postnatal period, and if clinically significant they are often corrected during infancy. Dengue virus infection during pregnancy increased the risk for any neurologic congenital anomaly in the infant by roughly 50% and for other congenital malformations of brain 4-fold. Congenital CMV and Birth Defects.

Cytomegalovirus, or CMV, is a very common member of the herpes family of viruses. By age 40, half of the adult population has been infected with CMV. Risks, and Treatment A molar pregnancy is an abnormality of the placenta, caused by a problem when the egg and sperm join together at fertilization.

Also. Zika virus infection during pregnancy can lead to congenital Zika syndrome and other birth defects. This webpage describes these outcomes and how healthcare providers can monitor infants for these findings. RESULTS: Of the 68 studies that met our inclusion criteria, 46 had an unexposed comparison group; of those, 30 performed statistical tests to measure associations between maternal opioid use during pregnancy and congenital malformations. Seventeen of these (10 of 12 case-control and 7 of 18 cohort studies) documented statistically significant positive associations.

Serious pre-existing disorders which can reduce a woman’s physical ability to survive pregnancy include a range of congenital defects (that is, conditions with which the woman herself was born, for example, those of the heart or reproductive organs, some of which are listed above) and diseases acquired at any time during the woman’s life. Congenital abnormalities and birth defects affect 2-3% of all pregnancies, with most of these being minor. A small minority of babies have major birth defects.

Although some congenital conditions can be inherited, the vast majority of birth defects are random events that affect people who had thought they were low risk. Diabetes mellitus or phenylketonuria, a rare genetic disease, during pregnancy also increases your risk for having a baby with congenital brain defects. Any type of trauma to the unborn child, such.

The risk of adverse outcome is increased if there is microcephaly, intracranial calcification, ventriculomegaly or evidence of a cerebral migration disorder (Ch. 40.8), and in these situations termination of pregnancy should be discussed.
