Background Hemoperitoneum is a life-threatening surgical emergency. Diagnosis of the cause is often difficult, in particular, during pregnancy when it may be either obstetric or nonobstetric. Case We report the case of a hemoperitoneum caused by the backflow of blood through a uterine tube, due to placental abruption. Conclusion Hemoperitoneum in pregnant women with no other signs can reveal pl...

The incidence of placental attachment disorders continues to increase with rising caesarean section rates. Antenatal diagnosis helps in the planning of location, timing and staffing of delivery. In at-risk women grey-scale ultrasound is quite sensitive, although colour ultrasound is the most predictive. Magnetic resonance imaging can add information in some limited instances. Patients who have ...

Placental transfusion has been cornpared in premature and full-term infants. Blood volume measurements showed that the 5-minute transfusion was similar in full-term and premature infants (47% and 50% increase in blood volume from birth) . A larger proportion of the 5-minute transfusion occurred by 1 minute in full-term ( 76%) than in premature infants (56%). Placental transfusion, by increasing...

In this article, I describe several benefits of using the World Wide Web (Web) for instructional purposes, and Ioffer 8 general tips on how to create and maintain an educational Web site. Most of these tips are easy to implement ifreaders have a basic grasp ofhypertext markup language (HTML, the language most Web pages are writ­ ten in). For readers who do not yet have experience with HTML, I p...

BACKGROUND AND PURPOSE The ubiquitous use of the Internet by the public in an attempt to better understand their health care requires the on-line resources written at an appropriate level to maximize comprehension for the average user. The National Institutes of Health and the American Medical Association recommend on-line patient education resources written at a third-to-seventh grade level. W...

Human papillomavirus (HPV) is an epitheliotropic virus typically infecting keratinocytes but also possibly epithelial trophoblastic placental cells. In the present study, we set out to investigate whether HPV can be recovered from transabdominally obtained placental cells to avoid any confounding contamination by HPV-infected cervical cells. Thirty-five placental samples from women undergoing t...

AIMS To study the localisation of the endothelial nitric oxide synthase (eNOS) in the normal placenta, with special emphasis on the implantation site in the first trimester of pregnancy, and in the different subtypes of trophoblastic cells in gestational trophoblastic disease. METHODS The immunoperoxidase technique with an antibody directed against eNOS was applied to paraffin sections from f...

Th e aim of the present study was to evaluate the eff ect of ovine placenta extract, obtained by affi nity chromatography on immobilized wheat germ lectin, on mammogenesis, lactogenesis, and galactopoiesis in pregnant and lactating sheep. Placental extract (100 μg/mL protein concentration) was subcutaneously injected to pregnant sheep in days 1, 4, 7, 10, and 13 of the experiment (totally 10 mL...

That endogenous retrovirus (ERV) is present within the placenta of humans and other mammals has been known for the past 25 years, but the significance of this observation is still not fully understood. Much molecular biological data have emerged in recent years to support the earlier electron microscopic data on the presence of placental ERV. The evidence for ERV in animal and human placental t...
