Congenital CMV infection (cCMV) is the most prevalent congenital infection, main non-genetic cause of sensorineural hearing loss (SNHL) and major cause of neurological disability. Despite the burden of cCMV, no Public Health body recommends universal serology screening in pregnancy. This was explained by gaps in knowledge of epidemiology, diagnosis, prognosis and the absence of any validated treatment. Read More

Introduction: The majority of early pregnancy losses are due to chromosomal abnormalities, which can be evaluated by testing the products of conception (POCs). Traditionally, a dilation and curettage (D&C) is recommended to patients to obtain suitable tissue for analysis. This case series sought to determine whether patients with first-trimester pregnancy losses can successfully obtain analysis of POCs if they pass tissue with expectant management or misoprostol, rather than D&C.

Eccentrically located intracavitary pregnancies, which include pregnancies traditionally termed as cornual and/or angular, have long presented complex diagnostic and management challenges given their inherent relationship to interstitial ectopic pregnancies. This review uses the existing literature to discriminate among interstitial, cornual, and angular pregnancies. Current arguments propose the outright abandonment of the terms cornual and angular may be justified in favor of the singular term, eccentric pregnancy. Read More

Background: Although spontaneous miscarriage is the most common complication of human pregnancy, potential contributing factors are not fully understood. Advanced maternal age has long been recognised as a major risk factor for miscarriage, being strongly related with fetal chromosomal abnormalities. The relation between paternal age and the risk of miscarriage is less evident, yet it is biologically plausible that an increasing number of genetic and epigenetic sperm abnormalities in older males may contribute to miscarriage.

Division of Family Planning, Department of Obstetrics and Gynecology, Hospital of the University of Pennsylvania, Philadelphia, PA.

Background: Early pregnancy loss is a common event in the first trimester, occurring in 15%-20% of confirmed pregnancies. A common evidence-based medical regimen for early pregnancy loss uses misoprostol, a prostaglandin E1 analog, with a dosage of 800 μg, self-administered vaginally. The clinical utility of this regimen is limited by suboptimal effectiveness in patients with a closed cervical os, with 29% of patients experiencing early pregnancy loss requiring a second dose after 3 days and 16% of patients eventually requiring a uterine aspiration procedure.

Recurrent pregnancy loss (RPL) is a clinically challenging scenario for patients and providers since an evidence-based approach to evaluation results in no explanation at least 50% of the time. The most common cause of first trimester clinical miscarriage is chromosome imbalance in the embryo or aneuploidy and the incidence of aneuploidy increases with age and diminished ovarian reserve (DOR). Currently, no professional societies recommend ovarian reserve testing in RPL patients, but some research shows a higher rate of DOR in miscarriage patients. Read More
