Birth defects are associated with multiple modifiable and nonmodifiable risk factors. Obstetrics providers should work with patients to minimize their risk of birth defects if modifiable risk factors are present and to appropriately counsel patients when nonmodifiable risk factors are present.
Importance Since 2013, the United States has seen a rise in cases of congenital syphilis, culminating in a relative increase of 153% from 2013 to 2017 and 918 reported cases in 2017. In all, 50% to 80% of pregnant women with syphilis experience an adverse pregnancy outcome including stillbirth or spontaneous abortion. Objective This article aims to review the current evidence and recommendations for management of syphilis in pregnancy. Evidence Acquisition Original research articles, review articles, and guidelines on syphilis were reviewed. Results In pregnancy, routine screening for syphilis is recommended on initiation of prenatal care. In high-risk populations, repeat testing is recommended in the early third trimester and at delivery. Penicillin remains the recommended treatment in pregnancy. After treatment, nontreponemal titers should be repeated at minimum during the early third trimester and at delivery to assess for serologic response. In high-risk populations, titers should be repeated monthly. Conclusion and Relevance Routine screening in pregnancy is essential for identification of syphilis infection and prevention of congenital syphilis. Subsequent adequate treatment with penicillin therapy more than 30 days before delivery and at the correct dosages depending on the stage of infection should be incorporated into clinical practice. Target Audience Obstetricians and gynecologists, family physicians Learning Objectives After completion of this educational activity, the obstetrician/gynecologist should be better able to summarize current knowledge of how syphilis impacts maternal and neonatal outcomes; describe the recommended screening and diagnostic tests for syphilis; and outline the treatment regimens and follow-up recommendations for management of syphilis in pregnancy.
Women with cervical dysplasia are at an increased baseline risk of preterm birth, and surgical excision confers additional risk. Pregnant patients with advanced cervical dysplasia or a history of surgical excision should be considered high-risk pregnancies.
The incidence of congenital heart disease is most commonly reported in 8 per 1000 live births. Situs anomalies are among the least common forms of congenital heart disease. This study defines situs and describes the variations of fetal situs anomalies. Situs refers to the arrangement of the viscera, atria, and vessels within the body. Situs solitus describes the normal arrangement; situs inversus describes inverted arrangement of the viscera and atria; and situs ambiguous (also referred to as heterotaxy) describes disturbances in arrangements that can neither be identified as solitus nor inversus. This review will concentrate on heterotaxy, as it is the most complicated situs abnormality to define, classify, and study. Prognosis of heterotaxy is variable but most correlated with cardiac anatomy. Management is concentrated on numerous cardiac operations and requires a multidisciplinary approach to address coexisting congenital anomalies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
