RESUMO
BACKGROUND AND PURPOSE: Studies in women with epilepsy (WWE) regarding pregnancy and labour complications have disclosed contradictory results. Our purpose was to investigate whether WWE have a higher risk of acute caesarean section (CS) or pregnancy complications than women without epilepsy or women with other chronic diseases and, if we found a higher risk, to explore potential explanations. METHODS: The study used prospectively registered obstetric data from the Oppland Perinatal Database in the period 2001-2011, containing information on 18 244 births, including 110 singleton pregnancies in mothers with validated epilepsy. Data regarding epilepsy were collected retrospectively from medical records. RESULTS: Epilepsy was a significant risk factor for acute CS, breech presentation and low birth weight in offspring [odds ratio (OR), 1.93, 95% confidence interval (CI), 1.2-3.1; OR, 2.29, 95% CI, 1.2-4.6 and OR, 2.10, 95% CI, 1.0-4.2, respectively]. In multivariate logistic regression analysis, antiepileptic drug exposure was an independent risk factor for acute CS (OR, 2.00; 95% CI, 1.06-3.77) and polytherapy was a significant risk factor for breech presentation (OR, 5.37; 95% CI, 1.13-25.57). Seizure frequency during pregnancy had no influence on the complication rate. CONCLUSIONS: We found that WWE using antiepileptic drugs during pregnancy had increased rates of acute CS, breech presentation and low birth weight, and that seizure frequency during pregnancy did not influence the complication rate.

The purpose of this study was to investigate the impact of hospital type determined at primary treatment and find possible predictors of survival in a cohort of patients with advanced epithelial ovarian cancer (EOC) who recurred twice and received three lines of treatment during eight-year follow-up. Using the Norwegian Cancer Registry, the authors identified 174 women with FIGO Stage IIIC EOC diagnosed in 2002. First-line treatment consisted of up-front debulking surgery and chemotherapy, received in either a teaching hospital (TH, n = 84) or a non-teaching hospital (NTH, n = 90). After recurrence all patients in Norway are equally consulted at TH. Survival determined for three time intervals (TI): TI-1, from end date of first-line treatment to first recurrence or death, TI-2, from beginning of second-line treatment until second recurrence or death, and TI-3, from beginning of third-line treatment to death or end of follow-up. Extensive surgery carried out in TH followed by at least six cycles of platinol-taxan chemotherapy resulted in longer survival in the TH group during TI-1. Altogether, the majority of those who receive treatment for recurrences were primary better debulked with following platinol-taxane chemotherapy. Survival in TI-2 was influenced by platinol-sensitivity. During TI-3 the majority (96%) had good performance status and their mean age at primary diagnosis at either hospital type was 57 years. Extensive primary surgery at TH, platinol sensitivity, age, and performance status were predictors of survival in this cohort.

OBJECTIVE: To confirm the results from two previous evaluations of term prediction models, including two sample-based models and one population-based model, in a third population. METHODS: In a study population of 23,020 second-trimester ultrasound examinations, data were prospectively collected and registered over the period 1988-2009. Three different models for ultrasonically estimated date of delivery were applied to the measurements of fetal biparietal diameter (BPD) and two models were applied to the femur length (FL) measurements; the resulting term estimations were compared with the actual time of delivery. The difference between the actual and the predicted dates of delivery (the median bias) was calculated for each of the models, for three BPD/FL-measurement subgroups and for the study population as a whole. RESULTS: For the population-based model, the median bias was + 0.4 days for the BPD-based predictions and - 0.4 days for the FL-based predictions, and the biases were stable over the inclusion ranges. The biases of the two traditional models varied with the size of the fetus at examination; median biases were - 0.87 and + 2.2 days, respectively, with extremes - 4.2 and + 4.8 days for the BPD-based predictions, and the median bias was + 1.72 days with range - 0.8 to + 4.5 days for FL-based predictions. The disagreement between the two sample-based models was never less than 2 days for the BPD-based predictions. CONCLUSION: This study confirms the results from previous studies; median biases were negligible with term predictions from the population-based model, while those from the traditional models varied substantially. The biases, which have clinical implications, seem inevitable with the sample-based models, which, even if overall biases were removed, will perform unsatisfactorily.

STUDY OBJECTIVE: Evaluation of the precision of routine ultrasound term prediction. DESIGN: Population based follow-up without intervention. SETTING: Ultrasound screening in routine clinical practice. MATERIAL: 1650 women residing in one Norwegian county giving birth during a 12-month period. All pregnancies were singleton with spontaneous onset of labor, all records contained a term predicted with routine ultrasound in the second trimester. OUTCOME MEASURE: Difference between actual and predicted day of delivery, and difference between ultrasound predicted term and term calculated from last menstrual period. MAIN RESULTS: More women delivered within two weeks of ultrasound term than two weeks of term calculated from the last menstrual period (87.5% and 79.3%, p < 0.001). Deliveries were significantly closer to the ultrasound predicted term than the term calculated from the last menstrual period, with the exception of deliveries in the 39th week after LMP where no significant difference was found between ultrasound term and LMP-term. No difference was found in the mean performance of 14 different ultrasound operators. CONCLUSIONS: In a population representative of deliveries in one county, routine ultrasound term prediction performed in three medium sized hospitals more accurately predicted day of delivery than term calculated from the date of last menstrual period.

OBJECTIVE: To analyse the effectiveness of antenatal care as a screening for nonsymptomatic disease and obstetrical risk conditions. DESIGN: Programme evaluation of antenatal care in a geographically based cohort. SETTING: Routine clinical practice in primary and specialist level of health care without intervention. SUBJECTS: One thousand nine hundred and eight women residing in one Norwegian county giving birth during a 12 month period, 1988 to 1989. OUTCOME MEASURES: The detection rates at the time of delivery, for women with five conditions: twin pregnancies, placenta praevia, breech presentation, small for gestational age (SGA) and pre-eclampsia. RESULTS: Two hundred and ninety-two women had one or more of the actual conditions, 124 (42%) had been diagnosed at the time of the delivery. The detection rate for SGA was remarkably low (14%). The detection rates for pre-eclampsia (75%), breech presentation (69%), placenta praevia (57%) and twin pregnancies (94%) were in the same range as results reported in the literature. The number of false positive antenatal diagnosis was insignificant. CONCLUSIONS: Assessing the effectiveness of antenatal diagnosis of growth retardation is connected with major unsolved methodological problems. Clinical management of such cases may be better than indicated by the results based on the ultimate SGA classification. For important obstetrical conditions this study describes an applicable method for practical evaluation of the effectiveness of antenatal care. Areas where care could be improved are demonstrated.

BACKGROUND: The community midwife services in Oppland county are under review. Many pregnant women live far from hospital. This is a study of the occurrence of deliveries during transport to hospital. MATERIAL AND METHODS: We used hospital records to identify women who had given birth during transport in Oppland county in the period 1989-97. We mailed a questionnaire to these and to 100 women who had given birth shortly after arrival at Lillehammer hospital in 1996-97. RESULTS: 133 women gave birth to 133 children during transport in Oppland 1989-97. This amounts to 0.69% of all births in the county. One child died during birth. A midwife assisted 71% of the women. However, only one third of these midwives had been on call at the time. Most women gave birth at night, and had their second child. INTERPRETATION: Deliveries during transport are inevitable and mostly uncomplicated. Midwives on call may provide qualified assistance during transport when the delivery is imminent.

BACKGROUND: We wanted to study a possible association between smoking during pregnancy and preterm birth. METHODS: A population based prospective study was performed among 7,236 consecutive pregnancies over seven years delivered at one birth clinic. Smoking habits were obtained at a routine ultrasound examination around 18 gestational weeks, and preterm birth was defined as delivery of a child between 24 and 37 gestational weeks. We estimated relative risk (odds ratio) between smoking, possible confounding variables and preterm birth using multiple logistic regression analysis. RESULTS: Overall, 1,769 (25%) women said that they smoked every day during their pregnancy. The smoking women had an increased risk of preterm delivery compared with non-smokers (odds ratio 1.53, 95% confidence interval 1.24, 1.89). However, this association was only demonstrated among the multiparous women (odds ratio 1.88, 95% confidence interval 1.39, 2.54). The association was statistically significant after adjusting for maternal age, diabetes, cervical conization, preeclampsia, placental abruption and placenta previa in a multivariate analysis, and we observed a dose-response effect of maternal smoking on preterm birth among multiparous women. CONCLUSION: For multiparous women smoking during pregnancy increases the risk of preterm delivery, and there seems to be a dose-response effect of smoking.

AIMS: To investigate the smoking prevalence the last three months before pregnancy and at 18 weeks of gestation among women in Norway and to evaluate the impact of pre-pregnancy smoking habits, maternal age, level of education, civil status and parity on smoking cessation. MATERIAL AND METHODS: A prospective, multicenter survey. The study population included 4 766 pregnant women who attended a routine ultrasound examination at 18 weeks of pregnancy in six Norwegian hospitals during the period from September 1994 to March 1995. Smoking habits before and during pregnancy were recorded. RESULTS: The point prevalence of self-reported daily smoking among the women three months before the pregnancy was 34%. At 18 weeks of pregnancy, 21% of the women reported smoking daily (p<0.001). A multiple logistic regression analysis revealed that a low number of cigarettes smoked per day during the last three months before pregnancy was the best predictor for smoking cessation. Educational level, maternal age, parity and civil status were also statistically significant contributors to smoking cessation. Eighty percent of the women who were unable to stop smoking, reported a reduction in cigarette consumption. The mean number of cigarettes per day was reduced from 13.9 before pregnancy to 7.3 at 18 weeks of pregnancy (p<0.001). CONCLUSION: In a national survey, 21% of the pregnant women reported smoking daily in the second trimester. Thirty-eight percent of the women who were daily smokers before the pregnancy stopped smoking in early pregnancy. A low cigarette consumption prior to the pregnancy was the best predictor for smoking cessation.
