The study of multiple gestations in older mothers has been furthered by the analyses of large data sets published in recent years. These initial analyses are counterintuitive in that the obstetric and neonatal outcomes of the older mothers (>40 years) are better than those of their younger counterparts (aged 25-29). Currently, it is not clear if older(More)
Triplet pregnancies are by nature rare. Assisted reproductive technologies have multiplied their rate of occurrence in the last two decades. Whether spontaneous or induced, triplet pregnancies present obstetric and neonatal-and then often lifelong-medical problems severalfold more often than singletons, or even twins. The major cause of problems for triplet(More)
It is generally accepted that menopausal symptoms can be controlled by HRT. As additional (putative) benefits of HRT were discovered, it was claimed that such uses were also important. Soon, trials were instituted to test these assertions, some of them quite large and projected to last a long time (> or = 5 years). The most instructive for medical practice(More)
Advances in neonatal care improved the survival of many preterm infants, but also increased the incidence of retinopathy of prematurity (ROP). Numerous risk factors have been associated with the development of ROP, the most important of which are: low birth weight, early gestational age at delivery, and duration of oxygen therapy. Screening premature(More)
OBJECTIVE To more precisely understand the changes in triplet births in recent years. STUDY DESIGN Analysis of recent government and medical publications pertaining to triplets. RESULTS Triplet births are at much greater risk than singletons of poor birth outcomes. More than 9 of 10 triplet births are born preterm (< 37 completed weeks of gestation) as(More)
Breast cancer is an equal opportunity killer in that as many as 60%-70% of breast cancer patients have no obvious risk factor(s). Thus, the continued reliance on the importance of risk factors to initiate screening programs may inhibit further inquiry into better diagnostic and prognostic indicators. An extensive review of past and recent literature reveals(More)
