INTRODUCTION: Lower plasma levels of vitamins may result in hyperhomocysteinemia, a known risk factor in pregnancy. As smoking may alter nutrition, we were interested in its effect on folate and Vitamin B(12) in pregnancy. MATERIALS AND METHODS: A cross-sectional study of 62 smoking and 76 non-smoking healthy pregnant women. Serum folic acid, Vitamin B(12) and homocysteine were measured at four points in pregnancy: 0-10, 11-20, 21-30 and 31-40 weeks. RESULTS: Folate concentrations of the smoking women decreased continuously during pregnancy, and were significantly lower than those of non-smoking women during the last 30 weeks. Vitamin B(12) levels decreased significantly in both groups. The homocysteine levels were higher in the smoking group during the second-half of pregnancy. DISCUSSION: Smoking women have lower and decreasing folate levels during pregnancy, possibly as a result of lower intake of these nutrients. Lower folate levels can lead to hyperhomocysteinemia, a known risk factor for several complications in pregnancy. This is an other important reason to convince pregnant women to refrain from smoking.

In this report we present the prenatal ultrasonic and postmortem data of a male fetus of 25 weeks' gestational age with a lethal multiple pterygium syndrome. The importance of precise etiologic diagnosis in a midtrimester fetus with generalized edema and nuchal hygroma is emphasized.

We report an unusual case of unilateral ureteral obstruction with secondary urinary extravasation by forniceal rupture as a complication of the Burch colposuspension procedure. Surprisingly, this complication has never been described before.

13 patients suspected of intra-uterine growth retardation (IUGR) were treated with a combination of heparin and dipyridamole. The effect of this anticoagulant therapy on platelet count, clot retraction, fibrinogen degradation products, antithrombin III (AT-III), plasminogen, fibrinogen and platelet aggregation induced by epinephrine, ADP, collagen and ristocetin has been examined. All parameters were measured both before and after treatment with heparin-dipyridamole. The results were compared with the results from a control group consisting of pregnant women of the same gestational age using no medication and not suspected of IUGR (n = 17). A significant decrease in the clot retraction was observed in patients with IUGR as compared to pregnant controls (p less than 0.05). A significant decrease in the AT-III level (p less than 0.01) and a significant increase (p less than 0.01) in the fibrinogen level were observed after heparin-dipyridamole treatment of patients suspected of IUGR. We conclude that the combination of a high fibrinogen and a low AT-III level will cause an increased risk for the development of thrombosis upon termination of treatment. We also observed that heparin clearance is increased during pregnancy.
