“…Placental calcification was seen significantly more frequently in primigravidas as cited by Russel J G B, Fielden P same results were observed in this study. Similar results are cited by Spirit B A, Cohen W N, Weinstein H M. [26,27] In PIH and in abruption of placentae APH mean number of calcified areas on gross as well as on microscopy seen were more than in normal placenta. In the study conducted by Majumandar S in Kolkkata and by Sarkar M in Mahattma Gandhi institute of medical science Sew gram India they have observed similar findings.…”

“…Calcification of the placenta in particular is common, and is associated with both normal pregnancies and a range of pathological conditions. Placental calcifications occur in most pregnancies after week 33 (>50%) and are universal in post-date pregnancies (Tindall and Scott, 1965; Spirt et al, 1982). Chorioamnionitis, a potentially fatal infection in which urogenital bacteria gain access to the amniotic membranes and placenta (Redline and Frcpa, 2007), can also result in marked tissue calcification.…”

Pregnancy complications are poorly represented in the archeological record, despite their importance in contemporary and ancient societies. While excavating a Byzantine cemetery in Troy, we discovered calcified abscesses among a woman’s remains. Scanning electron microscopy of the tissue revealed ‘ghost cells’, resulting from dystrophic calcification, which preserved ancient maternal, fetal and bacterial DNA of a severe infection, likely chorioamnionitis. Gardnerella vaginalis and Staphylococcus saprophyticus dominated the abscesses. Phylogenomic analyses of ancient, historical, and contemporary data showed that G. vaginalis Troy fell within contemporary genetic diversity, whereas S. saprophyticus Troy belongs to a lineage that does not appear to be commonly associated with human disease today. We speculate that the ecology of S. saprophyticus infection may have differed in the ancient world as a result of close contacts between humans and domesticated animals. These results highlight the complex and dynamic interactions with our microbial milieu that underlie severe maternal infections.DOI: http://dx.doi.org/10.7554/eLife.20983.001

“…Since amniotic fluid is produced by fetal urination and consumed by fetal swallowing and gastrointestinal tract resorption, abnormally high or low fluid volume should prompt careful sonographic evaluation of these fetal organ systems (133,134). Disparity of amniotic fluid volume between the two gestational sacs in a twin gestation is an important observation, the relationship between placental calcification and lung maturity (125)(126)(127), and placental grading has been largely abandoned.…”

During the past century, imaging of the pregnant patient has been performed with radiography, scintigraphy, computed tomography, magnetic resonance imaging, and ultrasonography (US). US imaging has emerged as the primary imaging modality, because it provides real-time images at relatively low cost without the use of ionizing radiation. This review begins with a discussion of the history and current status of imaging modalities other than US for the pregnant patient. The discussion then turns to an in-depth description of how US technology advanced to become such a valuable diagnostic tool in the obstetric patient. Finally, the broad range of diagnostic uses of US in these patients is presented, including its uses for distinguishing an intrauterine pregnancy from a failed or ectopic pregnancy in the first trimester; assigning gestational age and assessing fetal weight; evaluating the fetus for anomalies and aneuploidy; examining the uterus, cervix, placenta, and amniotic fluid; and guiding obstetric interventional procedures.
