Severe post-partum hemorrhage (PPH) is a major cause of maternal mortality worldwide. Recombinant activated factor VII (rFVIIa) has recently been approved by the European Medicines Agency for the treatment of severe PPH if uterotonics fail to achieve hemostasis. Although large randomized controlled trials are lacking, accumulated evidence from smaller studies and international registries supports the efficacy of rFVIIa alongside extended standard treatment to control severe PPH. Because rFVIIa neither substitutes the activity of a missing coagulation factor nor bypasses a coagulation defect in this population, it is not immediately evident how it exerts its beneficial effect. Here, we discuss possible mechanistic explanations for the efficacy of rFVIIa and the published evidence in patients with severe PPH. Recombinant FVIIa may not primarily increase systemic thrombin generation, but may promote local thrombin generation through binding to activated platelets at the site of vascular wall injury. This explanation may also address safety concerns that have been raised over the administration of a procoagulant molecule in a background of increased thromboembolic risk due to both pregnancy-related hemostatic changes and the hemorrhagic state. However, the available safety data for this and other indications are reassuring and the rates of thromboembolic events do not appear to be increased in women with severe PPH treated with rFVIIa. We recommend that the administration of rFVIIa be considered before dilutional coagulopathy develops and used to support the current standard treatment in certain patients with severe PPH.

Purpose: The contraceptive pill is an effective and safe method of preventing pregnancy. The progestins used for contraception either are components of a combined hormonal contraceptive (tablets, patches or vaginal rings) or are used alone in progestin-only formulations. Progestin-only contraceptives are available as daily oral preparations, subcutaneous or intramuscular injectables (every 1-3 months), subdermal implants (every 3-5 years) and intrauterine systems (every 3-5 years). Long-acting progestins are highly effective in typical use and have a very low risk profile and few contraindications.Material and Methods: A new progestin-only, oestrogen-free contraceptive, drospirenone, in a dosage of 4 mg/day in a 24/4 regimen, has received regulatory approval in the USA and the EU. The molecule has antigonadotropic, antimineralocorticoid, antiestrogenic and antiandrogenic properties.Results: The regimen was chosen to improve the bleeding profile; maintain plasma oestradiol levels at those of the early follicular phase, to avoid hypoestrogenism; and preserve efficacy even with a missed pill, as drospirenone has a half-life of 30-34 h.Conclusions: Clinical studies have shown good efficacy, very low cardiovascular side effects and a favourable bleeding pattern, as well as maintenance of ovulation inhibition after scheduled 24 h delays in pill intake.

The objective of the study was to estimate the association of pregnant women with varicose veins of lower extremities (VVLE) and the possible risk for adverse birth outcomes and among them different congenital abnormalities (CAs) in their children. Prospectively and medically recorded VVLE were evaluated in 332 pregnant women who delivered infants with CA (case group) and 566 pregnant women with VVLE who delivered infants without CA (control group) and matched to cases were compared in the population-based data set of the Hungarian Case-Control Surveillance System of Congenital Abnormalities, 1980-1996. About one-quarter of pregnant women had chronic VVLE while new onset VVLE occurred in the rest of pregnant women. There was no higher risk for adverse birth outcomes of pregnant women with VVLE, in fact the rate of preterm birth and low birth weight was somewhat lower than in the newborns of pregnant women without VVLE. The comparison of VVLE occurrence in pregnant women who had offspring with 21 different CA groups and in pregnant women who later delivered babies without CA showed a higher risk only for pectus excavatum, a mild CA. In conclusion, VVLE in pregnant women does not associate with obvious hazard for their fetuses.

BACKGROUND: Maternal cervical incompetence in pregnancy (CIP) showed an association with a higher rate of preterm births. The objective of this study was to determine the prevalence of CIP in Hungarian pregnant women, to determine the rate of preterm birth, and to check the preventive efficacy of preterm births due to CIP by therapeutic cerclage or bed rest alone. METHODS: Analysis of the population-based large data set of 38,151 newborns (without any defects) of the Hungarian Case-Control Surveillance System of Congenital Abnormalities (HCCSCA), born during 1980-1996, i.e. 1.8% of Hungarian newborns. Prospective cohort analysis based on medically recorded variables of CIP, birth weight and gestational age. RESULTS: A total of 2,795 (7.33%) newborns born to mothers with CIP. The newborns of mothers with CIP had a shorter gestational age at delivery (39.0 wk) and higher rate of preterm birth (11.1%) than the Hungarian reference sample without CIP (39.4 wk and 9.0%). Of 2,795 pregnant women with CIP 1,112 were treated by cerclage, while 1,683 with bed rest alone. The mean gestational age was shorter both after therapeutic cerclage (39.2 wk) and particularly bed rest alone (38.9 wk). The rate of preterm births was 9.1% and 12.7% after therapeutic cerclage and bed rest alone. CONCLUSIONS: CIP is very frequent in Hungary probably due the extremely high number of previous induced abortion performed by dilatation and curettage method. CIP associates with an increased risk for preterm births; however, this increased risk was reduced by bed rest alone and mainly by therapeutic cerclage.

OBJECTIVE: To study the association between common cold during pregnancy and pregnancy complications and delivery outcomes: gestational age/birth weight, in addition preterm birth and low birthweight. METHOD: In the population-based large data set of the Hungarian Case-Control Surveillance System of Congenital Abnormalities (HCCSCA), 1980-1996, controls without congenital abnormalities were analysed. RESULTS: Of 38,151 newborn infants, 5,475 (14.4%) had mothers with common cold. The prevalence of threatened preterm delivery, placental disorders and severe nausea and vomiting was lower while the occurrence of anemia was higher in pregnant mothers with common cold than in mothers without common cold. Mothers with common cold in pregnancy had 0.1 week shorter gestational age, thus the proportion of preterm births (9.8% vs 9.1%) was somewhat larger. However, mean birth weight was somewhat larger (3,305 vs 3,271 g) and the proportion of low birthweight newborns (4.2% vs 5.9%) was smaller. CONCLUSION: Common cold during pregnancy does not increase the occurrence of pregnancy complications except anemia, while delivery outcomes showed minor but opposite (higher rate of preterm birth and lower rate of low birthweight) changes.
