Acute recurrent polyhydramnios: a combination of amniocenteses and NSAID may be curative rather than palliative.

Acute recurrent polyhydramnios is a rare occurrence characterized by a poor fetal outcome. This is a case report describing a 34-year-old woman presenting with acute recurrent polyhydramnios. Treatment with non-steroidal anti-inflammatory drugs (NSAID) and therapeutic amniocenteses was initiated immediately and resulted in a decreased amniotic fluid production from 30 weeks' gestation. Even after the discontinuation of NSAID treatment, the amniotic fluid production normalized, and the woman delivered a healthy boy at 39 weeks 2 days' gestation. Amniotic prolactin was measured at three occasions using an enzyme-linked immunosorbent assay. As in normal pregnancies, amniotic prolactin levels decreased by 80% from highest to lowest value in this case of resolving acute recurrent polyhydramnios.

[Elective Caesarean section team--an organizational innovation].

INTRODUCTION: The increasing rate of delivery by caesarean section demands more effective use of resources in obstetrical departments and anaesthesiological departments. At the Danish State Hospital, Rigshospitalet, in 2002, we decided to optimise the cooperation between the various professionals involved, by softening the professional boundaries, and by performing most planned caesarean sections on the same day, carried out by the same team, the "elective caesarean section team" (EST). In 2003 a similar structure was established at Hvidovre Hospital. This paper describes the process of establishing EST, the organisational implications, and the results of an evaluation of EST by the users. MATERIALS AND METHODS: The case records of all caesarean sections performed by the EST-team at Rigshospitalet and Hvidovre Hospital in 2004, were examined. All users in a two-month period evaluated the EST by questionnaires at planned discharge. RESULTS: Most users (60.5%) were discharged after two days. The user evaluation showed a high level of satisfaction. CONCLUSION: The introduction of EST has increased the efficiency within the organisation for carrying out planned caesarean sections. It has generated a high level of satisfaction among users, and a high educational value for the staff.

[Complications of elective Caesarean section performed by a special section team].

INTRODUCTION: Two Danish hospitals have introduced a new organizing structure according to which planned caesarean sections are performed by a team. Caesareans are normally carried out without complications, and this makes it possible to evaluate complications to the surgery isolatedly. The object of this article was to describe the medical complications in mother and child of planned caesarean section performed in team. MATERIALS AND METHODS: A total of 534 caesarean sections were performed in team in 2004. Information on complications to caesarean sections was obtained from medical records. RESULTS: The most frequent complication was blood loss of more than 1000 millilitres occurring in 2,2%. Other complications occurred with frequencies of about or less than 1%. 7% of the patients experienced a complication to caesarean performed in team. Respiratory morbidity occurred in 3.2% of the infants. CONCLUSION: Concerning the short-term consequences, there is a low rate of fetal and maternal complications in these women in the low-risk group. Long-term consequences are not expected.

Spontaneous preterm delivery in primiparous women at low risk in Denmark: population based study.

OBJECTIVES: To analyse trends in preterm delivery and the factors contributing to preterm delivery in Denmark. To construct a standard population at low risk (white European, 20-40 years of age, with a singleton spontaneous pregnancy) and describe the changes in this population so that time trends can be compared internationally. DESIGN: Population based study. PARTICIPANTS: 99.8% of all deliveries in Denmark, 1995-2004. MAIN OUTCOME MEASURES: Proportion of babies born at less than 37 weeks' completed gestation for each year in the overall population and in a standard population at low risk. RESULTS: Overall, the proportion of preterm deliveries increased by 22% from 1995 to 2004. During the same period, known risk factors for preterm delivery such as in vitro fertilisation, multiple pregnancies, and elective deliveries also increased, and logistic regression analyses showed that these factors were associated with an increased risk of preterm delivery. Spontaneous preterm deliveries in primiparous women at low risk rose 51% (from 3.8% to 5.7%) during this time compared with 20% (2.7% to 3.2%) in multiparous women at low risk. CONCLUSIONS: The overall proportion of preterm deliveries increased significantly from 1995 to 2004 and primiparity and multiple birth were the most important contributing factors. The rise in spontaneous preterm deliveries in the standard population of primiparous women at low risk was greater than in the total population.

The relation of breech presentation at term to epilepsy in childhood.

OBJECTIVE: To investigate the relation between breech at term and epilepsy in childhood, and identify risk factors for epilepsy in term breech infants. STUDY DESIGN: Register-based study of all (n = 7514) singleton term infants without malformations, born between 1980 and 1994 and hospitalised with epilepsy until year 1996. For each case delivered in breech presentation (n = 290), the two subsequent deliveries of non-malformed, singleton infants delivered in breech presentation at term at the same hospital were selected as controls (n = 580). RESULTS: Breech presentation was a risk factor for epilepsy (OR: 1.2 [95% CI: 1.1, 1.3]). Breech infants with epilepsy were more often small for gestational age (9.7%) than breech infants without epilepsy (4.7%). Vaginal delivery was associated with low Apgar score, but mode of delivery and low Apgar score were not related to epilepsy. CONCLUSION: The increased risk of epilepsy in term breech infants is not related to intrapartum events, but to growth restriction in pregnancy.

Eclampsia in Scandinavia: incidence, substandard care, and potentially preventable cases.

BACKGROUND: Description of incidence, clinical signs, symptoms, and consequences of eclampsia in Scandinavia, and assessment of substandard care and potential preventability. METHODS: A descriptive cohort study including all women giving birth in a 2-year period (mid-1998-mid-2000) in Scandinavia. Notifications of eclampsia cases were obtained from all obstetric units at 3-monthly intervals. All patient files were reviewed, and systematic audit was performed to identify potentially preventable cases by using predefined criteria. MAIN OUTCOME MEASURES: Signs and symptoms preceding the eclamptic seizure, the standard of medical care, maternal and perinatal morbidity, and mortality were all recorded. Potentially preventable cases through improved care and cases eligible for primary prophylactic magnesium sulfate (MgSO4) were estimated. RESULTS: The incidence of eclampsia was 5.0/10,000 maternities (CI = 4.3-5.7/10,000). Eighty-six percent had a diagnosis of pre-eclampsia before the seizure. Nine of 10 had at least one physical complaint before the first seizure, severe headache being the most common symptom, occurring in two-thirds. Most seizures (90%) occurred after admission to hospital. By audit, 89 cases (42%) were classified as having received substandard care. Prophylactic use of magnesium sulfate might have reduced the number of eclampsia cases by 35 (17%). CONCLUSIONS: Eclampsia occurred mainly in hospital and the majority of women had symptoms heralding the seizure. In retrospect, nearly half of the cases were found potentially preventable by timely intervention, improved medical care, and systematic use of prophylactic treatment with MgSO4.

Placenta percreta treated using a new surgical technique.

Placenta percreta is still a life threatening condition due to the risk of excessive bleeding. Furthermore, it confers a considerable risk of the patient losing her uterus. An improved diagnosis including assessment of the depth of myometrial and serosal invasion is now available by color Doppler imaging, making the planning of elective caesarean section possible. We have designed a new operating technique, by which we successfully have achieved haemostasis of the areas containing the uterine arteries as well as the area between the bladder and the uterine cervix.

Inherited thrombophilias and adverse pregnancy outcome: screening and management.

Inherited thrombophilias are a heterogenous group of conditions which have been implicated in a variety of pregnancy complications. Evidence is mounting that implicates these inherited disorders in a range of pregnancy outcomes, including recurrent miscarriage, late fetal loss, preeclampsia, abruptio placentae, and intrauterine growth restriction. The most commonly identified inherited thrombophilias consist of Factor V Leiden and the prothrombin gene mutation G20210A. Rarer inherited thrombophilic conditions include deficiencies of protein S, C and antithrombin. More recently, deficiency of protein Z has been linked to pregnancy complications, including preterm delivery. Clinical manifestations often are associated with the presence of more than one inherited thrombophilia, consistent with their multigenic nature. Some, but not all, studies investigating the use of heparin to prevent adverse pregnancy outcome have demonstrated a benefit. However, an adequate randomized trial is required to definitively determine whether heparin anticoagulation is the best prevention option in patients who harbor one or more inherited thrombophilias and are at risk for adverse pregnancy outcome. This review will summarize the association of thrombophilic conditions and obstetrical complications.

Regional quality assessment in perinatal care.

Quality assessment is essential in every sector of health care and, in modern regionalized perinatal care, continuous data should be collected at all levels to give a stable basis for this activity. The discussion of definitions and choice of indicators is in itself an activity that will increase awareness of quality. Modern computer facilities will simplify data storage and analysis, but do not change the need to use a limited number of well-validated and appropriate variables.

Neonatal outcome in a Danish national cohort of 3438 IVF/ICSI and 10,362 non-IVF/ICSI twins born between 1995 and 2000.

BACKGROUND: In Denmark, one-third of twin pregnancies are the result of IVF/ICSI treatment. Limited data on neonatal outcome in IVF/ICSI twins are available in the literature. METHODS: A register study was conducted on neonatal morbidity and mortality in a complete national twin cohort including all 3438 (3393 live-born) IVF/ICSI and 10,362 (10,239 live-born) non-IVF/ICSI twins born between 1995 and 2000. Twins were identified in the National Medical Birth Registry and dichotomized into IVF/ICSI and non-IVF/ICSI by cross-reference with the Danish IVF Registry. Data on neonatal morbidity and mortality were retrieved from the Danish Patient Registry and the Danish Registry of Causes of Deaths. In order to exclude monozygotic twins, sub-analyses on unlike-sex twins were conducted. RESULTS: A birth weight discordance of >20% was observed in 20.6% of IVF/ICSI versus 15.7% of control twin pairs (P < 0.001). The risk of discordant birth weight >20% was OR 1.29 (95% CI 1.04-1.58) in unlike-sex IVF/ICSI twins versus control twins. The risk of delivery at <37 completed weeks and birth weight <2500 g was similar in the two cohorts; however, in unlike-sex IVF/ICSI versus control twins the risk of delivery at <37 weeks and birth weight <2500 g was OR 1.22 (95% CI 1.09-1.38) and OR 1.25 (1.11-1.40) respectively. After stratification for maternal age and parity, these risks disappeared. IVF/ICSI twins carried a higher risk of admittance to a neonatal intensive care unit (NICU) than control twins (OR 1.18, 95% CI 1.09-1.27), and this was even more pronounced in unlike-sex twins [OR 1.34 (95% CI 1.19-1.51)]. No differences were observed in malformation or mortality rates between the two cohorts. CONCLUSIONS: Despite higher birth weight discordance and more NICU admissions among IVF/ICSI twins, neonatal outcome in IVF/ICSI twins seems to be comparable with that of non-IVF/ICSI twins, when only dizygotic twins were considered in the comparisons.

Multiple birth and cerebral palsy in Europe: a multicenter study.

BACKGROUND: A European multicenter study (Surveillance of Cerebral Palsy in Europe, SCPE) was used to describe changes over time in multiple birth rates and cerebral palsy (CP) rates among multiple born infants, to compare CP rates and clinical types between multiples and singletons, and to analyse the influence of birth order in twins. METHODS: Data were collected from 12 European population-based CP registers on 6613 children born in 1975-90, as well as demographic data. RESULTS: The rate of multiple birth in the populations increased from 1.9% in 1980 to 2.4% in 1990, and the proportion of multiples among CP infants increased from 4.6% in 1976 to 10% in 1990. Multiples have a four times higher rate of CP than singletons [7.6 vs. 1.8 per 1000 live births, relative risk (RR) 4.36; 95% confidence interval (CI) 3.76-4.97] overall. The risk is marginally higher in multiples with birthweight > 2500 g (RR 1.60; 95% CI 0.95-2.28) and born at term (RR 1.65; 95% CI 0.91-2.40), and there is no difference in the risk for the low-birthweight and preterm groups. Correcting for differences in gestational age and birthweight, the clinical type of CP was the same in multiples and singletons. Twin CP infants are more often second than first born (56% vs. 44%, p < 0.05). CONCLUSIONS: Multiple born infants have a four times higher risk of developing cerebral palsy than singletons, mainly related to the higher risk of preterm birth in multiples. As the rate of multiples doubled through the 1980s, cerebral palsy cases in multiples increased in the same period.

A history of sexual abuse and health: a Nordic multicentre study.

OBJECTIVES: To determine if a history of sexual abuse is associated with objective and subjective indicators of health and if certain abusive incidents had a stronger impact on health than others. DESIGN: A cross-sectional, multicentre study. SETTING: Five gynaecological departments in the five Nordic countries. SAMPLE: Three thousand five hundred and thirty-nine gynaecology patients. METHODS: The NorVold Abuse Questionnaire (NorAQ) on abuse history and current health was mailed to all patients who consented to participate. MAIN OUTCOME MEASURES: Reason for index visit at the gynaeocological clinic as well as several questions on health were recorded. General health status was measured as self-estimated health, psychosomatic symptoms (headache, abdominal pain, muscle, weakness, dizziness), number of health care visits and number of periods on sick leave. RESULT: A history of sexual abuse was reported by 20.7% of respondents. A history of sexual abuse was significantly associated with chronic pelvic pain as reason for index visit (P < 0.01), laparoscopic surgery (P < 0.01), psychosomatic symptoms (P < 0.01), self-estimated poor health (P < 0.01), many health care visits (P < 0.01) and high incidence of sick leave (P < 0.01). Several subgroups within the group of sexually abused women were more likely to report poor health: women abused as both children and adults, women who experienced additional emotional and/or physical abuse and women abused by a person they knew. CONCLUSION: Sexual abuse has a profound impact on women's health. Taking a history of sexual abuse seems particularly warranted when the patient presents with chronic pelvic pain or symptoms of a vague and diffuse nature.

Maternal risks and perinatal outcome in a Danish national cohort of 1005 twin pregnancies: the role of in vitro fertilization.

BACKGROUND: Twin pregnancies constitute 25% of all in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) pregnancies. There is a lack of knowledge on maternal risks and perinatal outcome of IVF/ICSI twin pregnancies. METHODS: National survey by questionnaire (n = 1769). The study population consisted of all IVF/ICSI twin mothers (n = 266) and the two control groups of all IVF/ICSI singleton mothers (n = 764) and non-IVF/ICSI twin mothers (n = 739) who delivered in Denmark in 1997. The response rate was 89% among IVF twin mothers and overall 81%. RESULTS: In terms of maternal risks and perinatal outcome no significant differences were observed between IVF/ICSI twin and non-IVF/ICSI twin pregnancies after stratification for maternal age and parity. Nevertheless, IVF/ICSI twin mothers were more frequently on sick leave (OR 2.5, 95% CI 1.5-4.0) and hospitalized (OR 1.9, 95% CI 1.3-2.8) during pregnancy. Compared with IVF/ICSI singleton pregnancies, IVF/ICSI twin pregnancies were characterized by a higher incidence of preeclampsia (OR 2.4, 95% CI 1.5-4.2) and a higher frequency of sick leave (OR 6.8, 95% CI 4.4-10.5) and hospitalizations during pregnancy (OR 3.5, (95% CI 2.5-4.9); moreover, mean birthweight (p < 0.001) and gestational age (p < 0.001) were lower. No differences were observed in the incidence of pregnancy-induced hypertension and gestational diabetes between IVF/ICSI twin and singleton pregnancies. CONCLUSION: Although this population study indicates that maternal risks in IVF/ICSI twin pregnancies are comparable with non-IVF/ICSI twin pregnancies, the IVF/ICSI twin mothers were more likely to be on sick leave or hospitalized during pregnancy. Furthermore, maternal risks were higher and obstetric outcome poorer in IVF/ICSI twin vs. IVF/ICSI singleton pregnancies.

Indicators of fetal and infant health outcomes.

OBJECTIVE: To assess the ability of the member states of the European Union to produce the indicators recommended by the PERISTAT project on perinatal health indicators and to provide an overview of fetal and infant health outcomes for these countries according to the information now available. METHODS: We used data from the PERISTAT survey of data providers to compute PERISTAT indicators of fetal and infant health. RESULTS: National data on fetal mortality are available for all countries, but vary in their definitions. To adjust for these differences in definition, PERISTAT recommends presenting rates by gestational age and birth weight. Not all countries can provide neonatal mortality data by gestational age, birth weight or plurality, as recommended by PERISTAT. Few countries in Europe can report infant mortality rates by birth weight and gestational age. The other recommended indicators are available to varying degrees. CONCLUSIONS: This overview, which shows that Europe can produce a variety of indicators for monitoring the health of its new-borns, indicates that some key dimensions of perinatal health cannot now be measured with routine health statistics and reveals important disparities in health outcomes throughout Europe. For most indicators, the highest values are between 50 and 100% higher than the lowest values. The reasons for these variations and their importance for the surveillance of perinatal health are discussed.
