Age-specific birth rates in women with epilepsy: a population-based study.

Objective: The aim of this study was to investigate birth rates and use of hormonal contraception in different age groups among women with epilepsy (WWE) in comparison to women without epilepsy.

Materials And Methods: Demographic data and medical information on more than 25,000 pregnant women (40,000 births), representing 95% of all pregnancies in Oppland County, Norway, were registered in the Oppland Perinatal Database in the period 1989-2011. Data were analyzed with respect to epilepsy diagnoses, and 176 women with a validated epilepsy diagnosis (303 pregnancies) were identified.

Intrauterine growth retardation in foetuses of women with epilepsy.

Purpose: Various factors may affect intrauterine foetal growth, amongst which conditions such as epilepsy and the use of anti-epileptic drugs (AED) may play a role. This study investigated intrauterine growth of foetuses in women with epilepsy, as compared with controls, and explored whether intrauterine growth was affected by prenatal exposure to AED.

Method: Data were obtained from prospectively registered data regarding pregnancy and prenatal and perinatal factors in women in Oppland County in Norway.

Possible relation between maternal consumption of added sugar and sugar-sweetened beverages and birth weight--time trends in a population.

Background: High birth weight (BW) is a risk factor for later obesity. In Norway, mean BW and proportion of large newborns increased from 1989 to 2000 and subsequently decreased to the 1989 level by 2010. The purpose of the study was to explore causes of this temporary increase.

A 12-week randomised study comparing intravenous iron sucrose versus oral ferrous sulphate for treatment of postpartum anemia.

Objective: To analyze the effect of intravenous ferrous sucrose compared with oral ferrous sulphate on hematological parameters and quality of life in women with postpartum anemia.

Design: Open randomised controlled trial.

Setting: Multicentre study comprising five obstetrical departments in Norway.

Pregnancy risk increases from 41 weeks of gestation.

Background: The aim of this study was to evaluate the mortality and morbidity of conservatively managed post-term pregnancies (gestation 294 days and beyond).

Materials And Methods: This is a population-based prospective study. The sample was comprised of all women (N=17,493) with a singleton pregnancy in one Norwegian county from 1989 to 1999, with a second-trimester ultrasound examination and delivery after 37 completed gestational weeks.

Term prediction with ultrasound: evaluation of a new dating curve for biparietal diameter measurements.

Background: In Norway, routine ultrasound examination with assessment of gestational age was included in the standard antenatal care program in 1985. Until presently, a dating chart introduced in 1983 has been used throughout the country. New national normal values are now developed.

Routine ultrasound screening and detection of congenital anomalies outside a university setting.

Background: To assess the sensitivity for detecting fetal congenital anomalies by a routine ultrasound examination program at midtrimester performed in an unselected population by midwives and specialists in obstetrics and gynecology.

Methods: Six hundred seventy-six of the pregnancies had the midtrimester ultrasound examinations performed outside the county. Three hundred seventeen of the women had midtrimester ultrasound examinations performed in the county, but delivered outside the county.

The biologic error in gestational length related to the use of the first day of last menstrual period as a proxy for the start of pregnancy.

Objective: In a large unselected population of normal spontaneous pregnancies, to estimate the biologic variation of the interval from the first day of the last menstrual period to start of pregnancy, and the biologic variation of gestational length to delivery; and to estimate the random error of routine ultrasound assessment of gestational age in mid-second trimester.

Study Design: Cohort study of 11,238 singleton pregnancies, with spontaneous onset of labour and reliable last menstrual period. The day of delivery was predicted with two independent methods: According to the rule of Nägele and based on ultrasound examination in gestational weeks 17-19.

[Ultrasonography in primary health care--experiences within obstetrics 1983-99].

Background: In 1983 ultrasound for obstetric purposes was introduced in a rural general practice in south-eastern Norway. We wanted to evaluate its systematic use in terms of pregnancy management and birth outcome.

Material And Methods: Four sets of data were analysed: All obstetric ultrasound examinations done at the Sel Municipality Health Centre from 1 January 1998 to 28 February 1999; the database at the county hospital covering all obstetric patients and births in its catchment area, including those from the Sel community; all Medical Birth Registry reports on women from Sel from 1983 to 2000; a local register of pregnancy management and events in Sel from 1983 to 2000, organised by the local general practitioner.

Adverse obstetric outcome in fetuses that are smaller than expected at second trimester routine ultrasound examination.

Background: Adverse obstetric outcome in fetuses that are smaller than expected at second trimester routine ultrasound examination.

Aim: To assess the obstetric outcome when the interval between the estimated date of delivery by last menstrual period and the estimated date of delivery by second trimester ultrasound exceeds 14 days.

Materials And Methods: Population-based prospective cohort study.
