A randomised controlled trial of a psychoeducational intervention for women at increased risk of breast cancer.

This study aimed to compare the impact of two versions of a psychoeducational written intervention on cancer worry and objective knowledge of breast cancer risk-related topics in women who had been living with an increased risk of familial breast cancer for several years. Participants were randomised to three conditions: scientific and psychosocial information pack (Group 1), scientific information pack only (Group 2) or standard care control (Group 3). They completed postal questionnaires at baseline (n=163) and 4 weeks (n=151). As predicted, there was a significant decrease in cancer worry for Group 1, but not Group 2. Objective knowledge significantly improved for both Group 1 and Group 2 as expected, but not Group 3. However, there was an unpredicted decline in cancer worry for Group 3. This study supports the value of a scientific and psychosocial information pack in providing up-to-date information related to familial risk of breast cancer for long-term attendees of a familial breast cancer clinic. Further research is warranted to determine how the information pack could be incorporated into the existing clinical service, thus providing these women with the type of ongoing psychosocial support that many familial breast cancer clinics are currently lacking.

Three new European cases of urofacial (Ochoa) syndrome.

We report on three European cases of urofacial (Ochoa) syndrome. This entity was originally described in Colombian patients and very few cases have been reported from other countries. It is likely that they may be missed because of variability of the urinary problems and failure to recognize the characteristic facial grimacing. Establishing an early diagnosis has important consequences for the management and prognosis of urinary problems in these patients.

Further case of aminopterin syndrome sine aminopterin in a Spanish child.

We report on a Spanish child with clinical manifestations suggestive of aminopterin syndrome sine aminopterin (ASSA), having unusual hair pattern, syndactyly of fingers and toes, low-set thumbs, high-arched palate, and mild developmental delay. However, he does not show other characteristic features of ASSA such as ossification defects of the cranium, microcephaly, hypertelorism, cryptorchidism, or growth retardation. Differences from and similarities with Juberg-Hayward syndrome are discussed. Because few patients have been reported so far it is difficult to distinguish between these two conditions, and it may be that they are variants of the same nosological entity. Consanguinity of parents in this family supports autosomal recessive inheritance of ASSA.

Mutation analysis and embryonic expression of the HLXB9 Currarino syndrome gene.

The HLXB9 homeobox gene was recently identified as a locus for autosomal dominant Currarino syndrome, also known as hereditary sacral agenesis (HSA). This gene specifies a 403-amino acid protein containing a homeodomain preceded by a very highly conserved 82-amino acid domain of unknown function; the remainder of the protein is not well conserved. Here we report an extensive mutation survey that has identified mutations in the HLXB9 gene in 20 of 21 patients tested with familial Currarino syndrome. Mutations were also detected in two of seven sporadic Currarino syndrome patients; the remainder could be explained by undetected mosaicism for an HLXB9 mutation or by genetic heterogeneity in the sporadic patients. Of the mutations identified in the 22 index patients, 19 were intragenic and included 11 mutations that could lead to the introduction of a premature termination codon. The other eight mutations were missense mutations that were significantly clustered in the homeodomain, resulting, in each patient, in nonconservative substitution of a highly conserved amino acid. All of the intragenic mutations were associated with comparable phenotypes. The only genotype-phenotype correlation appeared to be the occurrence of developmental delay in the case of three patients with microdeletions. HLXB9 expression was analyzed during early human development in a period spanning Carnegie stages 12-21. Signal was detected in the basal plate of the spinal cord and hindbrain and in the pharynx, esophagus, stomach, and pancreas. Significant spatial and temporal expression differences were evident when compared with expression of the mouse Hlxb9 gene, which may partly explain the significant human-mouse differences in mutant phenotype.

Evaluation of the prenatal diagnosis of neural tube defects by fetal ultrasonographic examination in different centres across Europe.

OBJECTIVE: Evaluation of prenatal diagnosis of neural tube defects by ultrasound examination in unselected populations across Europe. SETTING: Prenatal ultrasound units in areas that report to contributing congenital malformation registers. METHODS: All cases with a suspected or confirmed neural tube defect and delivered within the 30 month study period were identified from 18 Congenital Malformation Registers from 11 European countries. Data on the pregnancy, prenatal scans, outcome of pregnancy, and information on different screening policies for each country were analysed. RESULTS: 670766 deliveries occurred in the area covered by the registers during the study period. A neural tube defect was diagnosed at delivery in 542 cases. In 84% of these, the lesion was isolated (166 anencephaly, 252 spina bifida, 35 encephalocele). Of the 166 isolated cases with anencephaly, 96% were correctly identified prenatally; one was missed on scan, two were wrongly diagnosed, and four were not scanned (sensitivity 98%). 84% of the prenatal diagnoses were made before 24 weeks' gestation; 86% of isolated anencephalic pregnancies were terminated. Of the 252 cases of isolated spina bifida, 171 (68%) were correctly identified prenatally; 66% of these before 24 weeks' gestation. The diagnosis was missed on scan in 60 cases and 21 were not scanned (sensitivity 75%). The mean reduction in birth prevalence because of termination of pregnancy for spina bifida was 49% (range 6-100%). There was a wide variation between centres in prenatal detection rate (33-100%), termination of pregnancy of prenatally diagnosed cases (17-100%), and gestation both at diagnosis and termination of pregnancy. CONCLUSION: A high prenatal detection rate for anencephaly was reported by all registers. There is a large variation in prenatal detection and termination rates for spina bifida between centres, reflecting differences both in policy and culture.

A study on limb reduction defects in six European regions.

Limb reduction defects (LRD) gained special attention after the thalidomide tragedy in 1962. LRD are common congenital malformations which present as obvious congenital anomalies recognized at birth. Therefore it might be assumed that they are well documented. However classification of LRDs is disputed as the identification of the exact site of the reduction(s) is hindered by imprecise information. This study was undertaken in 6 European countries to evaluate the use of the new classification proposed by EUROCAT for the epidemiologic and genetic study of LRD. The total number of births including livebirths, still-births and terminations, surveyed during 7 years by the 6 registries of congenital anomalies participating to this study was 611.150. The total prevalence of LRD was 7.06 per 10.000 births including the following categories prevalence : terminal transverse, 3.97, longitudinal, 1.75, proximal-intercalary, 0.10, split hand/foot 0.54 and multiple types 0.70. The prevalence of LRD was statistically higher in Basque Country, Odense, Strasbourg and Groningen than in Belfast and Emilia Romagna. Six per cent of the cases were chromosomal anomalies, including 15 trisomies 18 out of 26 cases, 49.5% (201 cases) were isolated LRD and 50.5% (206 cases) had other major non LRD associated malformations. Sex ratio and maternal age were not statistically different between regions and from the normal population. Multiply malformed with LRD had statistically significantly lower birthweight and lower gestational age than isolated cases with LRD, where available prenatal detection of LRD was higher in multiple malformed children with LRD than in isolated cases, 19.9% and 4.8% respectively. The precurrence risk was 1 in 37.

A distinct syndrome of familial cleft lip and palate with prominent eyes and characteristic facies in two unrelated families.

A variable degree of facial and oral clefting segregating with the characteristic facies, wide set prominent eyes, a broad nasal tip, and protruding external ears is described in several individuals spread over four generations in a British family and over two generations in a Spanish family. None of the affected individuals have any other developmental anomaly. The occurrence of oral and facial clefting associated with prominent eyes and characteristic facies probably indicates the existence of a distinct autosomal dominant syndrome.
