To investigate possible effects of implantation on apoptosis, we examined the cleavage of DNA in human chorionic villi and decidua in intrauterine and ectopic pregnancy. Very limited but detectable cleavage of DNA was recognized in the chorionic villi and decidua in normal pregnancy. A ladder pattern, characteristic of the apoptotic breakdown of DNA, was present in the villi in tubal pregnancy....

A woman, fitted with a Mirena intrauterine system (IUS), presented with a positive pregnancy test and a 5-day history of per vaginam bleeding and left iliac fossa pain. Beta-hCG level was raised at 1815 IU/l and a pelvic ultrasound scan showed a normal empty uterus. An abdominal x-ray showed that the IUS was in the left hypochondrium. At laparoscopy, an ectopic pregnancy was discovered in the l...

Heterotopic triplet pregnancy is an exceptionally rare medical condition. The broad use of assisted reproductive technologies has contributed to the increase of ectopic and subsequently heterotopic pregnancy rate, masking a life-threatening condition for the gravid and the intrauterine pregnancy. We describe a case of a woman with heterotopic triplets at 9(+4) gestational week following transfe...

Embryo implantation is a major prerequisite for the successful establishment of pregnancy. Ectopic implantation outside the intrauterine cavity and the development of ectopic pregnancy (EP) is a major cause of maternal morbidity and occasionally mortality during the first trimester. EP may be induced by failure of tubal transport and/or increased tubal receptivity. Activins, their type II recep...

Normal trophoblast growth is one of the more important stages of early pregnancy that has a deciding factor on its later development and normal outcome. Identifying pregnant women who have a high risk of complications connected to hypertension during pregnancy is currently one of the most important tasks of perinatal medicine. Abnormal placentation is related not only to the appearance of preec...

INTRODUCTION Heterotopic pregnancy is a life-threatening complication of pregnancy defined as coexistent intrauterine and ectopic gestation. Its diagnosis is frequently overlooked and delayed. CASE OUTLINE A 28-year-old woman experienced acute abdominal pain in pregnancy achieved by in vitro fertilization. Since all previous checkups indicated a normal course of pregnancy, the ectopic pregnan...

BACKGROUND Hypertensive disorders of pregnancy and intrauterine growth restriction (IUGR) are leading causes of maternal and perinatal morbidity and mortality. Failure to detect intrauterine growth restriction in women at high risk has been highlighted as a significant avoidable cause of serious fetal outcome. In this observational study we compare fetal flow using Doppler ultrasonography with ...

Leucocytes at the ectopic implantation site in 10 cases of early tubal pregnancy were characterised with a series of monoclonal antibodies using an indirect immunoperoxidase technique on cryostat sections. Most were HLA-DR positive macrophages, and there were a small number of mature T lymphocytes (UCHT1 and Dako-T1 positive cells). These results were compared with those reported in normal firs...

INTRODUCTION Complications of copper load intrauterine devices, including ectopic pregnancies are well reported. Rates of ectopic pregnancy are 0.6 to 1.1% per year. However, the levonorgestrel intrauterine device has been described as more protective against ectopic pregnancies due to the addition of the hormone levonorgestrel. The hormone released from the intrauterine device causes some syst...
