INTRODUCTION: French health professionals are now required to provide relevant information on the test screening for Down syndrome and its possible implications when making the test available to pregnant women. A questionnaire was designed to assess prescription modalities, explanation of results, opinion on the information received when test was offered and test results were given, and likely decision after screening. RESULTS: The response rate was 39% (1473 questionnaires analyzed). In 90.5% of the answers, women declared that an interview had preceded test prescription. 61.2% of women were satisfied with both the clarity and quantity of explanations provided and 57.6% considered that the information had helped them decide to undergo or refuse screening. 54.1% were satisfied with the explanations of test results. Amniocentesis was proposed to 125 women, 79.2% of which decided to undergo the procedure. Their opinion concerning explanations of test results was similar to that of women who refused amniocentesis or had not yet made up their minds. CONCLUSION: Such results demonstrate the necessity to improve and adapt the information delivered by health professionals, keeping in mind that in this type of situation, decision making requires the rapid integration of complex information.

Microcephalic osteodysplastic primordial dwarfism Taybi-Linder type: report of four cases and review of the literature.

Microcephalic and osteodysplastic primordial dwarfism (MODP) types I, II, and III were defined by Majewski et al. in 1982. This group of syndromes was characterized by intrauterine growth retardation, microcephaly, and typical facial appearance with prominent nose and micrognathia. Type II was clearly different, both clinically and radiologically, whereas types I and III shared manifestations. Distinction between the latter two was established on the basis of subtle radiological differences. In 1967, Taybi and Linder described another syndrome with microcephalic congenital dwarfism. There is a consensus that MODP type I and III and Taybi-Linder cephaloskeletal dysplasia represent the same disorder. We report on four patients with MODP type Taybi-Linder syndromes, two of whom were born to unrelated but consanguineous parents, while the other two were sibs. Second-trimester prenatal detection by ultrasonography was possible in one case. Consanguinity in two cases and recurrence among sibs are consistent with autosomal recessive inheritance.

Neonatal death in Marshall-Smith syndrome.

Marshall-Smith syndrome is characterized by accelerated skeletal maturation, failure to thrive and dysmorphic features. Since 1971, twenty cases of MSS have been reported. We describe another patient with a very early death demonstrating the clinical variability of the syndrome and the importance of systematic X rays of the skeleton for determining the causes of fetal or neonatal death.

Distribution of single organ malformations in European populations. EUROCAT Working Group.

The aim of this study was to evaluate the prevalence of congenital anomalies in 19 areas from 13 European countries. A total of 291,126 births were surveyed. On average most of the anomalies were recorded in livebirths. The total prevalence of congenital anomalies was 21.8 per 10,000 births. Four groups of congenital anomalies were of particular note in the consideration of geographic variations: neural tube defects, cleft lip, limb reduction defect and Down syndrome. For neural tube defects, 24 cases per 10,000 were recorded in the British Isles whereas only 9.6 cases per 10,000 were registered in Continental Europe. Cleft lip had a much higher prevalence in Groningen (The Netherlands) and in Odense (Denmark) than in the other European countries under study. The prevalence of limb reduction defect was high in Bilbao (Spain), in Odense, in Strasbourg (France) and in Groningen. In the study population the prevalence of Down syndrome ranged from 5.6 to 21.3 per 10,000 livebirths.

Maternal occupational exposure and congenital malformations.

A case-referent study was conducted to assess the risk of congenital malformations in relation to maternal occupational exposure before and during pregnancy. Three hundred and twenty-five cases of major malformations and 325 normal (at birth) referents identified in 15 maternity hospitals were included in the study. The occupational history obtained from an interview of the mother was blindly reviewed by an industrial hygienist who assessed the presence of chemical exposure and the probability of exposure. The results suggested that mothers of the case children with oral clefts were more often exposed to solvents during pregnancy [odds ratio (OR) 7.9, 90% confidence interval (90% CI) 1.8-44.9] and worked more often as cleaners (four cases, no referents). Digestive anomalies (OR 11.9, 90% CI 2.0-149) and multiple anomalies (OR 4.5, 90% CI 1.4-16.9) were also associated with occupational exposure to solvents at work. These results were not modified when differences in maternal age, area of residence, and socioeconomic status were taken into account.

Kabuki make-up (Niikawa-Kuroki) syndrome: a study of 16 non-Japanese cases.

Kabuki make-up (Niikawa-Kuroki) syndrome has been described mainly in Japanese patients. In this paper we report sixteen new cases from Europe and North America, suggesting that Kabuki make-up syndrome may be more common outside of Japan than supposed. Their features are compared with those of the Japanese patients and most of our findings are similar to those previously reported. The facial phenotype is specific and easily recognizable, regardless of ethnic origin. Postnatal growth retardation and mild mental retardation are confirmed to be cardinal manifestations of the syndrome. Skeletal anomalies were present in all cases but most of the radiological changes were non-specific. The specificity of metacarpophalangeal pattern profile is not confirmed. Conversely, dermatoglyphic analysis is helpful in the diagnosis of this condition. Two differences have emerged between the Japanese patients and those in this study. Firstly, two-thirds of the patients in this series had significant neurological dysfunction other than mental retardation. Secondly, joint hypermobility appears more common in non-Japanese patients. Confirmation of these findings requires further studies.

Heterogeneity of neural tube defects in Europe: the significance of site of defect and presence of other major anomalies in relation to geographic differences in prevalence.

In the period 1980-1987, neural tube defects were two to three times more prevalent in populations covered by EUROCAT registries in the United Kingdom and Ireland (UKI) than in Continental Europe and Malta (CEM). 1864 NTD cases in a total population of 580,000 births in UKI and 455 cases in a population of 380,000 births in CEM were analysed to find if there were differences in the ratio of prevalence rates between UKI and CEM according to site of the defect and association with non-central nervous system (CNS) anomalies. The prevalence rate ratio was high for anencephaly with accompanying spina bifida, iniencephaly, and upper spina bifida, and low for encephalocele, lower spina bifida, and anencephaly without other neural tube defects. There was a greater female excess for anencephaly with accompanying spina bifida, iniencephaly, and upper spina bifida than for other defects in both geographic areas. There was a female excess for encephalocele in UKI but a male excess in CEM. Certain sites (anencephaly with accompanying spina bifida, iniencephaly, and encephalocele) were more likely to have accompanying non-CNS anomalies. The prevalence rate ratio of multiply malformed NTD was in general lower than for isolated NTD but showed the same pattern by site. The prevalence rate ratio was high for multiply malformed anencephaly with accompanying spina bifida, iniencephaly, and upper spina bifida. The sex ratio was similar between isolated and multiply malformed cases when site of the defect is taken into account. It is concluded that the geographic prevalence pattern and sex ratio differ according to site of NTD but do not differ substantially according to whether NTD is isolated or associated with non-CNS anomalies.

Epidemiological study of congenital diaphragmatic defects with special reference to aetiology.

Congenital diaphragmatic defects (CDD) are easily accessible to ultrasonographic diagnosis. In spite of progress in the management of prenatally detected cases, the mortality rate for CDD remains high. The prognosis depends mainly on the severity of fetal lung hypoplasia but is also linked to the associated malformations. We report on 77 cases of CDD ascertained between 1982 and 1988 from 136,161 consecutive births in the Bouches du Rhône area. The spontaneous perinatal mortality rate was 61% with 28 early post-natal deaths and 14 stillbirths. Eight pregnancies were terminated after prenatal diagnosis. The diaphragmatic defect was associated with other congenital anomalies in 33 cases, more often among stillborn (92.8%) than liveborn infants (23.6%). A chromosomal abnormality was present in 9 cases representing 11.6% of all CDD and in 27.2% of cases with other anomalies. A Mendelian disorder was present in 9 cases (eight Fryns syndrome and one Fraser syndrome). This study underlines the necessity of a systematic work up of prenatally diagnosed cases, including fetal karyotyping and analysis of associated malformations in order to adapt the management of the pregnancy and delivery to the prognosis.

Socio-cultural inequities in access to prenatal diagnosis: the role of insurance coverage and regulatory policies.

The article presents the results of a 4-month-period survey by questionnaire among all women attending the Marseille Centre for Prenatal Diagnosis for amniocentesis. Socio-cultural status of women getting access to amniocentesis is significantly higher than in the general population of pregnant women in the same geographic area of south-eastern France. Socio-cultural status is also higher among women who have to cover costs of procedure to get access to amniocentesis than among those who benefit from it free-of-charge according to French Social Security regulations. In contrast, risk perception and attitudes toward termination of pregnancy are similar in these two groups. A total of 24.4 per cent of respondents declared that they got access to amniocentesis 'on their own initiative', the remaining 75.6 per cent declaring that they 'were following medical advice'. Multidimensional analysis shows that the women who do not benefit from free-of-charge amniocentesis, and who have a high level of education and no antecedents of fetal and perinatal deaths, are more likely to perceive themselves as 'self-referring'. The study indicates that institutional coverage may be effective in reducing socio-cultural inequities in access to prenatal diagnosis. But such a policy may conflict with the respect of women's individual autonomy in the amniocentesis decision.

[Retrospective study on abortions of malformed fetuses carried out during a 5-year period in the department of Bouches-du-Rhône].

The authors report a retrospective study of therapeutic abortions for antenatally diagnosed abnormalities, 146 fetuses are concerned during a five years period, an anatomo-pathological examination have been performed in all cases, malformations of central nervous system are the most frequent (62). 26 urologic abnormalities are especially detailed. There are 10 isolated urologic abnormalities, and 16 abnormalities multiples. All fetuses had renal lesions which could justified an intervention but the declaration at registration of congenital birth defects is not obligatory. A multidisciplinary approach to prenatal diagnosis and congenital birth must still developed for a better understanding.

[Cost-benefit analysis of amniocentesis in the prenatal diagnosis of chromosome abnormalities].

The article presents a cost-benefit analysis of amniocentesis for detection of chromosomal anomalies based on data (1985/87) collected in the Marseille area. In this geographic area, it is possible to confront, in an exhaustive manner, pregnant women's access to amniocentesis and incidence of fetal anomalies due to chromosomal aberrations. Results show that prenatal diagnosis is highly cost-beneficial, the average cost of one "avoided" case of Down's syndrome being lower than the lifelong costs of care for such a child. However, the study emphasizes that the cost-benefit ratio is highly sensitive to the implicit value society affects to the loss of "normal" fetuses through spontaneous abortions provoked by amniocentesis and because of terminations of pregnancy following diagnosis of minor fetal anomalies. The study also shows that lowering maternal age limit for access to free-of-charge amniocentesis from the current 38 years of age to 35 would have been cost-beneficial. Such lowering of the maternal age limit is discussed and compared with other indications which might be used for systematic access to amniocentesis.
