[Tertiary obstetric care: the aims of the planning decree on perinatal care of 2001 have not yet been achieved]. / Derdelijns verloskundige zorg: doelstellingen van het 'planningsbesluit bijzondere perinatologische zorg' uit 2001 nog niet gehaald.

OBJECTIVE: To compare the actual situation in tertiary perinatal care in the Netherlands with the objectives laid down in the 2001 decree on perinatal care by the Dutch Ministry of Health, Welfare and Sport. DESIGN: Descriptive, retrospective. METHOD: Data on tertiary perinatal care, the transfer or refusal of women with very endangered pregnancies and the personnel of obstetric high care (OHC) units in 2006 were compared with the targets laid down in the planning decree on perinatal care and in a report by the Dutch Health Council from 2000. Parameters of tertiary perinatal care output were the number of admissions, and the number of beds in OHC units and neonatal intensive care units (NICU). RESULTS: In 2006, 128 of the 250 beds intended for OHC had been obtained. The degree of capacity utilisation was 94%, while the norm is 80%. 312 women were transferred due to lack of capacity of OHC units and NICU. The number of staff, specialised physicians as well as nurses, was considerably lower than the planned capacity. But training for obstetric perinatologists and OHC nurses was given. CONCLUSION: The targets for the number of beds for tertiary obstetric care and associated medical personnel have not been achieved as yet. As a consequence, the number of transfers is still too high. The funding of OHC units is not attuned to the complexity of tertiary perinatal care. Closer supervision of the execution of the planning decree and an adequate financing system are needed to achieve the objectives of the planning decree in the next 3 years.

The association between hypertensive disorders of pregnancy and abnormal second-trimester maternal serum levels of hCG and alpha-fetoprotein.

OBJECTIVE: To examine the association between hypertensive disorders of pregnancy and second-trimester maternal serum alpha-fetoprotein (MSAFP) and hCG levels. METHODS: The proportions of abnormal second-trimester MSAFP and hCG levels in the serum samples from 65 women with true pregnancy-induced hypertension or preeclampsia (cases) were compared to the proportions of abnormal levels in all 1943 women without this disorder in the same cohort in a hospital setting. Maternal serum alpha-fetoprotein and hCG levels of the 65 cases also were compared to those of 325 completely uncomplicated matched control pregnancies, selected from the same cohort. Fisher exact test and Student t test were used for statistical analysis and P < .05 was considered statistically significant. RESULTS: An MSAFP level at least 2.5 multiples of the median (MoM) was found in two of 65 cases (3.1%) and in 27 of 1943 women (1.4%) in the rest of the cohort, a nonsignificant difference (relative risk [RR] = 2.2; P = .24). The statistical power to identify a significant difference for this RR was .27. An hCG level of at least 2.5 MoM was found in six cases (9.2%) and in 89 (4.6%) of women in the rest of the cohort, also a nonsignificant difference (RR = 2.0; P = .12). The statistical power to identify a significant difference for this RR was .38. The mean (+/-standard deviation) logarithms of the MSAFP and hCG MoMs in the 65 cases (0.039 +/- 0.191 and 0.048 +/- 0.265, respectively) were not significantly different from those in the 325 matched controls (0.006 +/- 0.148 and -0.010 +/- 0.244, respectively; P = .12 and .08, respectively). CONCLUSION: Although a weak association cannot be excluded, this study found no clinically important increase in risk of developing subsequent hypertensive disorders of pregnancy among women with abnormal second-trimester levels of MSAFP or hCG.

Connections between primary vaginismus and procreation: some observations from clinical practice.

So far, the literature on vaginismus has mainly been contemplative. Quantitative data are scarce, while fertility and obstetrical aspects are almost never considered. In this article, these two aspects are addressed. A cohort of patients received a questionnaire, developed to obtain information about possible connections between the vaginistic reaction, the patient's treatment goals and, if relevant, obstetrical characteristics. Our data reveal that the desire to have a child is not a negative predictor for treatment outcome in terms of consummation. In some instances, however, self-insemination, as a bedroom procedure, is an effective treatment option to enable the couple to reach their fertility goal. Some women will conceive without intercourse experience; according to our data, delivery in this group is hardly more problematic than in a group of women who, after treatment for vaginismus, conceived by sexual intercourse. Having delivered a child may have a slightly positive effect on the capability to have intercourse, but only in a minority. Obstetricians should be aware that not infrequently, women give birth who suffer from severe penetration phobias.

[The practice guideline 'Pregnancy and puerperium' (first revision) from the Dutch College of General Practitioners; a response from the perspective of gynaecology]. / De standaard 'Zwangerschap en kraamperiode' (eerste herziening) van het Nederlands Huisartsen Genootschap; reactie vanuit de gynaecologie.

The major benefit of the revised version of the Dutch College of General Practitioners' practice guideline about pregnancy and puerperium is the formal starting point of professional equality of midwives and general practitioners as care providers in antenatal and postpartum care. This thorough evidence-based practice guideline is behind the most recent developments in this field. Scientific evidence on vertical HIV transmission favours screening all pregnant women and not just the selective procedure proposed in this guideline. The restrictive attitude towards routine ultrasound screening during pregnancy hardly seems in line with scientific evidence and the public demand. On the other hand the guideline is very progressive as far as the care of women with thyroid disorders is concerned even though evidence on this subject is meagre. Most importantly the transition of antenatal care from the current almost conveyor belt-like procedure to an efficient but individually-adapted care process was not addressed.

[Women's opinion concerning oocyte donation for pre-embryonic studies]. / Meningen van vrouwen over eiceldonatie voor pre-embryo-onderzoek.

For the benefit of pre-embryonal research, women requesting sterilization may be asked whether they are prepared to donate egg cells. Recently, a questionnaire was sent to 144 women who had given birth to their second or third child at the University Hospital Groningen, asking them how they felt about egg cell donation: 68 (47%) of the questionnaires was returned. Of the respondents 45 (66%) felt that a request for donation could be made to women who were admitted to hospital for sterilization. 22 (32%) of the respondents said they would be willing to donate an egg cell themselves. Of these women, 10 said they would be willing to use hormone preparations for this purpose.

[Pregnancy after liver transplantation in Groningen: benign course for mothers and children]. / Zwangerschappen na levertransplantatie in Groningen: gunstig beloop voor moeder en kind.

OBJECTIVE: Analysing the course and outcome of pregnancies in liver transplant recipients. DESIGN: Retrospective and descriptive. METHOD: Since 1979 liver transplantations have been performed in the University Hospital Groningen, the Netherlands. Seven female patients conceived 12 times after transplantation. These pregnancies were managed by a team of liver transplantation specialists and obstetricians. Hypertensive disorders, foetal growth, liver function tests and infective disorders were monitored specially. The course and outcome of the pregnancies were determined. RESULTS: The incidence of complications was much lower than in published patient series. The differences in premature deliveries (9 versus 40%) and caesarean births (18 versus 57%) are largely explained by the difference of incidence of hypertensive disorders (18 versus 35%). One woman developed a liver function disorder during pregnancy (9 versus 38%). In the long term the function of the donor liver appeared not to be disturbed; this finding is in accordance with data from other reports. Ten of the 12 pregnancies resulted in the birth of a healthy child. All children were born in good condition and all of them were alive at the completion of the study (minimal follow-up: 10 months). CONCLUSION: After liver transplantation there is no need to advise against pregnancy.

The Tulip classification of perinatal mortality: introduction and multidisciplinary inter-rater agreement.

OBJECTIVE: To introduce the pathophysiological Tulip classification system for underlying cause and mechanism of perinatal mortality based on clinical and pathological findings for the purpose of counselling and prevention. DESIGN: Descriptive. SETTING: Tertiary referral teaching hospital. POPULATION: Perinatally related deaths. METHODS: A classification consisting of groups of cause and mechanism of death was drawn up by a panel through the causal analysis of the events related to death. Individual classification of cause and mechanism was performed by assessors. Panel discussions were held for cases without consensus. MAIN OUTCOME MEASURES: Inter-rater agreement for cause and mechanism of death. RESULTS: The classification consists of six main causes with subclassifications: (1) congenital anomaly (chromosomal, syndrome and single- or multiple-organ system), (2) placenta (placental bed, placental pathology, umbilical cord complication and not otherwise specified [NOS]), (3) prematurity (preterm prelabour rupture of membranes, preterm labour, cervical dysfunction, iatrogenous and NOS), (4) infection (transplacental, ascending, neonatal and NOS), (5) other (fetal hydrops of unknown origin, maternal disease, trauma and out of the ordinary) and (6) unknown. Overall kappa coefficient for agreement for cause was 0.81 (95% CI 0.80-0.83). Six mechanisms were drawn up: cardio/circulatory insufficiency, multi-organ failure, respiratory insufficiency, cerebral insufficiency, placental insufficiency and unknown. Overall kappa for mechanism was 0.72 (95% CI 0.70-0.74). CONCLUSIONS: Classifying perinatal mortality to compare performance over time and between centres is useful and necessary. Interpretation of classifications demands consistency. The Tulip classification allows unambiguous classification of underlying cause and mechanism of perinatal mortality, gives a good inter-rater agreement, with a low percentage of unknown causes, and is easily applicable in a team of clinicians when guidelines are followed.

Antenatal care; current practice in debate.

The antenatal screening practice of 67 teaching hospitals in the European Community was assessed by use of a written questionnaire. There were minor differences in mean numbers of tests performed in different countries, but only limited agreement was found on the selection of tests that were performed. There was no unity of practice within the countries. No correlations were found between the number of screening tests performed and the size of the units, or the composition of the attending staff.

The influence of serum screening on the amniocentesis rate in women of advanced maternal age.

We investigated the effect of maternal serum screening on the amniocentesis (AC) rate in women of advanced maternal age. The AC rate after maternal serum screening was compared in two groups of women with a singleton pregnancy, 855 women of 30-35 years and 98 of 36 years and older. In our population, 34.1 per cent of the women of 36 years or older were 'screen-positive' for Down syndrome. Only 41.2 per cent of these women chose to undergo AC as opposed to 88.2 per cent in the younger age group. Within the older age group, the tendency to avoid AC increased with increasing age. Maternal serum screening led to a significant decrease in the AC rate in the older women. In this group, a comparison between the 'a priori' and the calculated risk might have had more influence on the decision to undergo AC than being screen-positive or screen-negative as such. We conclude that maternal serum screening had a major effect on the AC rate in women of advanced maternal age. This is of importance in a society in which the average maternal age is steadily increasing.

Nuchal translucency cannot be used as a screening test for chromosomal abnormalities in the first trimester of pregnancy in a routine ultrasound practice.

We decided to assess the practicability of introducing nuchal translucency (NT) measurements as a screening programme for fetal Down's syndrome in the first trimester of pregnancy, within the population of women who receive ultrasound examinations in our department. Over a 1-year period, measurements were made in 923 fetuses at < or = 13 weeks' gestation. Fifty-two per cent of the mothers were 36 years or older or had a past history of a chromosomally abnormal fetus or child. Measurements were only successful 58 per cent of the time; this improved to 74 per cent if the fetus was > or = 10 weeks' gestation. Inter-observer variability did not cause a major problem. There were 36 fetuses with an NT > or = 3 mm. Two of these fetuses had a chromosomal abnormality (both trisomy 21). The translucency in these two cases was so large that they would have been detected and offered prenatal diagnosis even prior to this study. There was a total of ten aneuploidies in the study group. Only two of these fetuses were detected by this screening method; five had an NT measurement < 3 mm and in three fetuses (all trisomy 21), measurements were not successful. We outline the practical problems that could be expected by introducing ultrasound screening in a routine setting. Although the efficacy of the test in a research setting may seem good, the effectiveness in everyday usage appears much less impressive, making its uptake as a screening technique in a general ultrasound practice at this stage imprudent.

The HELLP syndrome: its association with unexplained elevation of MSAFP and MShCG in the second trimester.

In this study, we examined the relationship between concentrations of maternal serum alpha-fetoprotein (MSAFP) and maternal serum human chorionic gonadotropin (MShCG) in the second trimester and the haemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome. The concentrations of both serum markers, expressed in multiples of the median (MOM), in 16 women with the HELLP syndrome were compared with those in 10443 women without this syndrome who were screened for Down's syndrome and neural tube defects. All the women with a singleton pregnancy and a known pregnancy outcome were included in this study. At a cut-off level of 2.5 MOM, 37.5 per cent of the pregnancies with the HELLP syndrome had an elevated MShCG level, compared with 4.8 per cent in the whole population (P < 0.0001). 12.5 per cent of the women with the HELLP syndrome had an elevated MSAFP level, compared with 1.3 per cent in the whole population (P < 0.025). Women with a combined elevation of MSAFP and MShCG levels (0.3 per cent of the screened population) had a 47 time greater risk of developing the HELLP syndrome than the others (P < 0.01). The HELLP syndrome should be taken into account in the case of unexplained elevated levels of MShCG and MSAFP, especially in the rare event of combined elevation of both markers.
