Children with Hirschsprung's disease have high morbidity in the first 5 years of life.

BACKGROUND: Hirschsprung's disease is a rare congenital anomaly of the colon with absence of the ganglionic nerve cells. The treatment of the anomaly is surgical. METHODS: This population-based data-linkage cohort study was part of the EUROlinkCAT project and investigated mortality and morbidity for the first 5 years of life for European children diagnosed with Hirschsprung's disease. Nine population-based registries in five countries from the European surveillance of congenital anomalies network (EUROCAT) participated. Data on children born 1995-2014 and diagnosed with Hirschsprung's disease were linked to hospital databases. All analyses were adjusted for region and length of follow-up, which differed by registry. RESULTS: The study included 680 children with Hirschsprung's disease. One-year survival was 97.7% (95% CI: 96.4-98.7). Overall, 85% (82-87) had a code for a specified intestinal surgery within the first year increasing to 92% (90-94) before age 5 years. The median age at the first intestinal surgery up to 5 years was 28 days (11-46) and the median number of intestinal surgical procedures was 3.5 (3.1-3.9). Thirty days mortality after neonatal surgery (within 28 days after birth) was 0.9% (0.2-2.5) for children with a code for intestinal surgery within the first 28 days after birth and there were no deaths for children with a code for stoma surgery in the neonatal period. CONCLUSION: Children with Hirschsprung's disease have a high morbidity in the first 5 years of life requiring more surgical procedures in addition to the initial surgery. Mortality after neonatal surgery is low.

The Association of Prenatal Diagnoses with Mortality and Long-Term Morbidity in Children with Specific Isolated Congenital Anomalies: A European Register-Based Cohort Study.

OBJECTIVES: To compare 5-year survival rate and morbidity in children with spina bifida, transposition of great arteries (TGA), congenital diaphragmatic hernia (CDH) or gastroschisis diagnosed prenatally with those diagnosed postnatally. METHODS: Population-based registers' data were linked to hospital and mortality databases. RESULTS: Children whose anomaly was diagnosed prenatally (n = 1088) had a lower mean gestational age than those diagnosed postnatally (n = 1698) ranging from 8 days for CDH to 4 days for TGA. Children with CDH had the highest infant mortality rate with a significant difference (p < 0.001) between those prenatally (359/1,000 births) and postnatally (116/1,000) diagnosed. For all four anomalies, the median length of hospital stay was significantly greater in children with a prenatal diagnosis than those postnatally diagnosed. Children with prenatally diagnosed spina bifida (79% vs 60%; p = 0.002) were more likely to have surgery in the first week of life, with an indication that this also occurred in children with CDH (79% vs 69%; p = 0.06). CONCLUSIONS: Our findings do not show improved outcomes for prenatally diagnosed infants. For conditions where prenatal diagnoses were associated with greater mortality and morbidity, the findings might be attributed to increased detection of more severe anomalies. The increased mortality and morbidity in those diagnosed prenatally may be related to the lower mean gestational age (GA) at birth, leading to insufficient surfactant for respiratory effort. This is especially important for these four groups of children as they have to undergo anaesthesia and surgery shortly after birth. Appropriate prenatal counselling about the time and mode of delivery is needed.

Higher risk of cerebral palsy, seizures/epilepsy, visual- and hearing impairments, cancer, injury and child abuse in children with congenital anomalies: Data from the EUROlinkCAT study.

AIM: The aim is to examine the risk of cerebral palsy, seizures/epilepsy, visual- and hearing impairments, cancer, injury/poisoning and child abuse in children with and without a congenital anomaly up to age 5 and 10 years. METHODS: This is a population-based data linkage cohort study linking information from the European Surveillance of Congenital Anomalies network (EUROCAT) and birth registries to hospital discharge databases. We included 91 504 live born children with major congenital anomalies born from 1995 to 2014 from nine EUROCAT registries in five countries and 1 960 727 live born children without congenital anomalies (reference children). Prevalence and relative risk (RR) were estimated for each of the co-morbidities using Kaplan-Meier survival estimates. RESULTS: Children with congenital anomalies had higher risks of the co-morbidities than reference children. The prevalences in the reference children were generally very low. The RR was 13.8 (95% CI 12.5-15.1) for cerebral palsy, 2.5 (95% CI 2.4-2.6) for seizures/epilepsy, 40.8 (95% CI 33.2-50.2) for visual impairments, 10.0 (95% CI 9.2-10.9) for hearing loss, 3.6 (95% CI 3.2-4.2) for cancer, 1.5 (95% CI 1.4-1.5) for injuries/poisoning and 2.4 (95% CI 1.7-3.4) for child abuse. CONCLUSION: Children with congenital anomalies were more likely to be diagnosed with the specified co-morbidities compared to reference children.

Timing of Cardiac Surgical Interventions and Postoperative Mortality in Children With Severe Congenital Heart Defects Across Europe: Data From the EUROlinkCAT Study.

BACKGROUND: The purpose of this study was to evaluate the timing of the first cardiac surgery, the number of cardiac surgeries performed, and 30-day postoperative mortality rate for children with severe congenital heart defects (sCHDs) in their first 5 years of life. METHODS AND RESULTS: This was a population-based data linkage cohort study linking information from 9 European congenital anomaly registries to vital statistics and hospital databases. Data were extracted for 5693 children with sCHDs born from 1995 to 2004. Subgroup analyses were performed for specific types of sCHD. Children with sCHDs underwent their first surgical intervention at a median age of 3.6 (95% CI, 2.6-4.5) weeks. The timing of the first surgery for most subtypes of sCHD was consistent across Europe. In the first 5 years of life, children with hypoplastic left heart underwent the most cardiac surgeries, with a median of 4.4 (95% CI, 3.1-5.6). The 30-day postoperative mortality rate in children aged <1 year ranged from 1.1% (95% CI, 0.5%-2.1%) for tetralogy of Fallot to 23% (95% CI, 12%-37%) for Ebstein anomaly. The 30-day postoperative mortality rate was highest for children undergoing surgery in the first month of life. Overall 5-year survival for sCHD was <90% for all sCHDs, except transposition of the great arteries, tetralogy of Fallot, and coarctation of the aorta. CONCLUSIONS: There were no major differences among the 9 regions in the timing, 30-day postoperative mortality rate, and number of operations performed for sCHD. Despite an overall good prognosis for most congenital heart defects, some lesions were still associated with substantial postoperative death.

The burden of disease for children born alive with Turner syndrome-A European cohort study.

BACKGROUND: Turner syndrome is a rare congenital anomaly caused by complete or partial X chromosome monosomy that may affect mortality and morbidity in childhood. METHODS: This population-based data-linkage cohort study, as part of the EUROlinkCAT project, investigated mortality and morbidity for the first 5 years of life for liveborn European children diagnosed with Turner syndrome. Thirteen population-based registries in 10 countries from the European surveillance of congenital anomalies (EUROCAT) network participated. Data on children born 1995-2014 and diagnosed with Turner syndrome were linked to mortality, hospital and prescription records. Children with any congenital anomaly and children without a congenital anomaly were included for comparison on morbidity. RESULTS: Out of a population of 5.8 million livebirths 404 were diagnosed with Turner syndrome prenatally or in infancy and 95.5% survived to their fifth birthday. During the first year of life 72.3% (95% CI 59.5;81.6) of children with Turner syndrome were hospitalized, the median length of stay was 5.6 days (95% CI 3.5;7.7) and 18.7% (95% CI 13.9;23.9) underwent surgery. After the first year of life hospitalizations and length of stay decreased but more children underwent surgery (30.8% [95% CI 17.6;44.7]). In the first 5 years the percentage of children with Turner syndrome having a prescription for antibiotics was 12%-20% per year and increased with the age of child. CONCLUSIONS: In the first year of life, the burden of disease was relatively high for children with Turner syndrome. The outlook is more positive beyond the first year, though overall morbidity still exceeded that of children without congenital anomalies.

Survival, hospitalisation and surgery in children born with Pierre Robin sequence: a European population-based cohort study.

OBJECTIVE: To evaluate survival, hospitalisations and surgical procedures for children born with Pierre Robin sequence (PRS) across Europe. DESIGN: Multicentre population-based cohort study. SETTING: Data on 463 live births with PRS from a population of 4 984 793 from 12 EUROCAT congenital anomaly registries. METHODS: Data on children with PRS born 1995-2014 were linked electronically to data on mortality, hospitalisations and surgical procedures up to 10 years of age. Each registry applied a common data model to standardise the linked data and ran common syntax scripts to produce aggregate tables. Results from each registry were pooled using random-effect meta-analyses. MAIN OUTCOME MEASURES: Probability of survival, proportion of children hospitalised and undergoing surgery, and median length of hospital stay. RESULTS: The majority of deaths occurred in the first year of life with a survival rate of 96.0% (95% CI 93.5% to 98.5%); 95.1% (95% CI 92.7% to 97.7%) survived to age 10. In the first year of life, 99.2% (95% CI 95.0% to 99.9%) of children were hospitalised with a median stay of 21.4 days (95% CI 15.6 to 27.2), and 67.6% (95% CI 46.6% to 81.8%) underwent surgery. In the first 5 years of life, 99.2% of children underwent a median of two surgical procedures. Between ages 5 and 9, 58.3% (95% CI 44.7% to 69.7%) were hospitalised with a median annual stay of 0.3 days. CONCLUSIONS: Children with PRS had high mortality and morbidity with long hospital stays in the first year of life, and almost all had surgery before 5 years of age. Survival improved after infancy with fewer hospitalisations after age 5. This study provides reliable estimates of the survival and morbidity of children with PRS for families and healthcare providers.

Hospital Length of Stay and Surgery among European Children with Rare Structural Congenital Anomalies-A Population-Based Data Linkage Study.

Little is known about morbidity for children with rare structural congenital anomalies. This European, population-based data-linkage cohort study analysed data on hospitalisations and surgical procedures for 5948 children born 1995-2014 with 18 rare structural congenital anomalies from nine EUROCAT registries in five countries. In the first year of life, the median length of stay (LOS) ranged from 3.5 days (anotia) to 53.8 days (atresia of bile ducts). Generally, children with gastrointestinal anomalies, bladder anomalies and Prune-Belly had the longest LOS. At ages 1-4, the median LOS per year was ≤3 days for most anomalies. The proportion of children having surgery before age 5 years ranged from 40% to 100%. The median number of surgical procedures for those under 5 years was two or more for 14 of the 18 anomalies and the highest for children with Prune-Belly at 7.4 (95% CI 2.5-12.3). The median age at first surgery for children with atresia of bile ducts was 8.4 weeks (95% CI 7.6-9.2) which is older than international recommendations. Results from the subset of registries with data up to 10 years of age showed that the need for hospitalisations and surgery continued. The burden of disease in early childhood is high for children with rare structural congenital anomalies.

European study showed that children with congenital anomalies often underwent multiple surgical procedures at different ages across Europe.

AIM: Children with congenital anomalies often require surgery but data on the burden of surgery for these children are limited. METHODS: A population-based record-linkage study in Finland, Wales and regions of Denmark, England, Italy and Spain. A total of 91 504 children with congenital anomalies born in 1995-2014 were followed to their tenth birthday or the end of 2015. Electronic linkage to hospital databases provided data on inpatient surgical procedures and meta-analyses of surgical procedures were performed by age groups. RESULTS: The percentage of children having surgery in the first year was 38% with some differences across regions and 14% also underwent surgery at age 1-4 years. Regional differences in age at the time of their first surgical procedure were observed for children with cleft palate, hydronephrosis, hypospadias, clubfoot and craniosynostosis. The children had a median of 2.0 (95% CI 1.98, 2.02) surgical procedures before age 5 years with children with oesophageal atresia having the highest median number of procedures (4.5; 95% CI 3.3, 5.8). CONCLUSION: A third of children with congenital anomalies required surgery during infancy and often more than one procedure was needed before age 5 years. There was no European consensus on the preferred age for surgery for some anomalies.

Epidemiology of aplasia cutis congenita: A population-based study in Europe.

BACKGROUND: Aplasia cutis congenita (ACC) is a rare congenital anomaly characterized by localized or widespread absence of skin at birth, mainly affecting the scalp. Most information about ACC exists as individual case reports and medium-sized studies. OBJECTIVES: This study aimed to investigate the epidemiology of ACC, using data from a large European network of population-based registries for congenital anomalies (EUROCAT). METHODS: Twenty-eight EUROCAT population-based registries in 16 European countries were involved. Poisson regression models were exploited to estimate the overall and live birth prevalence, to test time trends in prevalence between four 5-year periods and to evaluate the impact of the change of coding for ACC from the unspecific ICD9-BPA code to the specific ICD10 code. Proportions of ACC cases associated with other anomalies were reported. RESULTS: Five hundred cases were identified in the period 1998-2017 (prevalence: 5.10 per 100,000 births). Prevalence across 5-year periods did not differ significantly and no significant differences were evident due to the change from ICD9 to ICD10 in ACC coding. Heterogeneity in prevalence was observed across registries. The scalp was the most common site for ACC (96.4%) and associated congenital anomalies were present in 33.8% of cases. Patau and Adams-Oliver syndromes were the most frequent among the associated chromosomal anomalies (88.3%) and the associated genetic syndromes (57.7%), respectively. 16% of cases were associated with limb anomalies and 15.4% with congenital heart defects. A family history of ACC was found in 2% of cases. CONCLUSION: To our knowledge, this is the only population-based study on ACC. The EUROCAT methodologies provide reliable prevalence estimates and proportions of associated anomalies.

Information needs of parents of children with congenital anomalies across Europe: a EUROlinkCAT survey.

BACKGROUND: Parents of children who have a congenital anomaly can experience significant worry about their child's health. Access to clear, helpful, and trustworthy information can provide a valuable source of support. In this study the aim was to explore the information needs of parents/carers of children with congenital anomalies across Europe. METHOD: A cross-sectional online survey was developed in nine languages to measure parents' information needs, including: (1) the 'helpfulness'/'trustworthiness' of information received from eight relevant sources, and (2) overall satisfaction with information received. Parents/carers of children (0-10 years) with cleft lip, spina bifida, congenital heart defect [CHD] requiring surgery, and/or Down syndrome were recruited online via relevant organisations in 10 European countries from March-July 2021. Quantitative analyses using multivariable logistic regressions were performed. RESULTS: One thousand seventy parents/carers of children with a cleft lip (n = 247), spina bifida (n = 118), CHD (n = 366), Down syndrome (n = 281), and Down syndrome with CHD (n = 58) were recruited in Poland (n = 476), the UK (n = 120), Germany (n = 97), the Netherlands/Belgium (n = 74), Croatia (n = 68), Italy (n = 59), other European countries (n = 92), and not specified/non-European countries (n = 84). Most participants were mothers (92%) and aged 31-40 years (71%). Participants were most likely to rate support groups (63%), patient organisations (60%), specialist doctors/nurses (58%), and social media (57%) as 'very helpful' information sources. 'Very trustworthy' ratings remained high for specialist doctors/nurses (61%), however, they declined for support groups (47%), patient organisations (48%), and social media (35%). Germany had the highest proportion of participants who were 'very satisfied' (44%, 95% CI = 34%-54%) with information, whereas this percentage was lowest in Croatia (11%, 95% CI = 3%-19%) and Poland (15%, 95% CI = 11%-18%). Parents of children with Down syndrome had significantly lower satisfaction ratings than parents of children with CHD; 13% (95% CI = 8%-18%) reported being 'very satisfied' compared to 28% (95% CI = 23%-33%) in the CHD group. CONCLUSIONS: Findings suggest that informal sources of information (e.g. support groups) are of value to parents, however, they are not deemed as trustworthy as specialist medical sources. Satisfaction ratings differed across countries and by anomaly, and were particularly low in Croatia and Poland, as well as for parents of children with Down syndrome, which warrants further investigation.

Gastrostomy and congenital anomalies: a European population-based study.

OBJECTIVE: To report and compare the proportion of children with and without congenital anomalies undergoing gastrostomy for tube feeding in their first 5 years. METHODS: A European, population-based data-linkage cohort study (EUROlinkCAT). Children up to 5 years of age registered in nine EUROCAT registries (national and regional) in six countries and children without congenital anomalies (reference children) living in the same geographical areas were included. Data on hospitalisation and surgical procedures for all children were obtained by electronic linkage to hospital databases. RESULTS: The study included 91 504 EUROCAT children and 1 960 272 reference children. Overall, 1200 (1.3%, 95% CI 1.2% to 1.6%) EUROCAT children and 374 (0.016%, 95% CI 0.009% to 0.026%) reference children had a surgical code for gastrostomy within the first 5 years of life. There were geographical variations across Europe with higher rates in Northern Europe compared with Southern Europe. Around one in four children with Cornelia de Lange syndrome and Wolf-Hirschhorn syndrome had a gastrostomy. Among children with structural anomalies, those with oesophageal atresia had the highest proportion of gastrostomy (15.9%). CONCLUSIONS: This study including almost 2 million reference children in Europe found that only 0.016% of these children had a surgery code for gastrostomy before age 5 years. The children with congenital anomalies were on average 80 times more likely to need a gastrostomy before age 5 years than children without congenital anomalies. More than two-thirds of gastrostomy procedures performed within the first 5 years of life were in children with congenital anomalies.

Prescription of cardiovascular medication in children with congenital heart defects across six European Regions from 2000 to 2014: data from the EUROlinkCAT population-based cohort study.

OBJECTIVES: Advances in surgical management strategies have substantially reduced fatality from congenital heart defects (CHD). Decreased infant mortality might be expected, consequentially to result in greater morbidity in older children due to complications later in childhood and adolescence. This study aims to evaluate the use of cardiovascular medication (CVM) as an indicator of disease burden in children born with CHD in the first 10 years of life. DESIGN: Population-based cohort study. SETTING: Six population-based registries from the European Surveillance of Congenital Anomalies (EUROCAT) network participated. Data from live born children with major congenital anomalies (CA) born from 2000 to 2014 were linked to prescription databases. Four groups of children were analysed: CA, CHD, severe CHD (sCHD) and ventricular septal defect (VSD) without sCHD. Live born children without CA were included as reference group. PARTICIPANTS: We obtained data on 61 038 children born with a CA, including 19 678 with CHD, 3392 with sCHD, 12 728 children with VSD without sCHD, and 1 725 496 reference children. RESULTS: Children born with sCHD were the most likely to receive a CVM prescription (42.9%, 95% CI, 26.3 to 58.5) in the first year of life compared with 13.3% (6.7 to 22.0) of children with any CHD, 5.9% (3.7 to 8.7) of children with any CA and 0.1% (0.0 to 0.1) of reference children. Medication was less likely to be prescribed after the first year of life for sCHD; 18.8% (14.8 to 23.1) for children 1-4 years and 15.8% (12.0 to 20.1) 5-9 years. Children with sCHD were most likely to receive a diuretic (36.4%, 18.6 to 54.5), an antihypertensive (6.9%, 3.7 to 11.3) or a beta-blocker (5.5%, 2.9 to9.2). CONCLUSION: Almost half of all children with sCHD were prescribed CVM in their first year of life. For all four groups of children with anomalies, the proportion of children with a CVM prescription decreased with age.

The Voice of Parents of Children With a Congenital Anomaly - A EUROlinkCAT Study.

EUROlinkCAT aims to investigate the health and educational outcomes of children with congenital anomalies for the first 10 years of their lives. We also aim to facilitate the development of a more reciprocal relationship between families with children with congenital anomalies, health and social care professionals, and researchers by conducting focus groups. The aim of the focus groups and parent interviews was to investigate parental experiences of having a child with a heart defect requiring surgery, cleft lip, spina bifida or Down Syndrome and to identify their research priorities. In total, seven interviews with 12 parents and eight focus groups with 58 parents and two caregivers were conducted in four European countries. We found that parents request more positive information with a focus on quality of life and what the children can achieve rather than solely on the negative aspects and limitations of the congenital anomaly. Some parents also highlighted discrepancies between the family's need for support and the lack of support received from the local authority. Finally, it was challenging for the parents to address specific research priorities. Future research should therefore focus on the potential of a child with a congenital anomaly.

Epidemiology of Dandy-Walker Malformation in Europe: A EUROCAT Population-Based Registry Study.

BACKGROUND: Dandy-Walker (DW) malformation is a rare and severe congenital anomaly of the posterior fossa affecting the development of the cerebellum and the fourth ventricle. OBJECTIVE: The aim of this study was to investigate the epidemiology of DW malformation, using data from the European population-based registries of congenital anomalies in the European Surveillance of Congenital Anomalies network. METHODS: Anonymous individual data on cases of DW malformation diagnosed in 2002-2015 from 28 registries in 17 countries were included. Prevalence, prenatal detection rate, proportions and types of associated anomalies were estimated. Cases of DW variant were considered and analysed separately. RESULTS: Out of 8,028,454 surveyed births we identified a total of 734 cases, including 562 DW malformation cases and 172 DW variant cases. The overall prevalence of DW malformation was 6.79 per 100,000 births (95% CI 5.79-7.96) with 39.2% livebirths, 4.3% foetal deaths from 20 weeks gestational age, and 56.5% terminations of pregnancy after prenatal diagnosis of foetal anomaly at any gestation (TOPFA). The livebirth prevalence was 2.74 per 100,000 births (95% CI 2.08-3.61). The prenatal detection rate was 87.6%. Two-hundred and seventy-three cases (48.6%) had an isolated cerebral anomaly and 24.2, 19.2 and 5.5% cases were associated with other structural non-cerebral anomalies, chromosomal anomalies and genetic syndromes respectively. The prevalence of DW variant was 2.08 per 100,000 (95% CI 1.39-3.13). CONCLUSIONS: This European population-based study provides the epidemiological profile of DW malformation. All birth outcomes were analysed and TOPFA represented more than half of the cases. About 50% of the cases of DW malformation were associated with other non-cerebral anomalies. Large populations and all birth outcomes are essential in epidemiological studies of rare and severe congenital anomalies.

Epidemiology of achondroplasia: A population-based study in Europe.

Achondroplasia is a rare genetic disorder resulting in short-limb skeletal dysplasia. We present the largest European population-based epidemiological study to date using data provided by the European Surveillance of Congenital Anomalies (EUROCAT) network. All cases of achondroplasia notified to 28 EUROCAT registries (1991-2015) were included in the study. Prevalence, birth outcomes, prenatal diagnosis, associated anomalies, and the impact of paternal and maternal age on de novo achondroplasia were presented. The study population consisted of 434 achondroplasia cases with a prevalence of 3.72 per 100,000 births (95%CIs: 3.14-4.39). There were 350 live births, 82 terminations of pregnancy after prenatal diagnosis, and two fetal deaths. The prenatal detection rate was significantly higher in recent years (71% in 2011-2015 vs. 36% in 1991-1995). Major associated congenital anomalies were present in 10% of cases. About 20% of cases were familial. After adjusting for maternal age, fathers >34 years had a significantly higher risk of having infants with de novo achondroplasia than younger fathers. Prevalence was stable over time, but regional differences were observed. All pregnancy outcomes were included in the prevalence estimate with 80.6% being live born. The study confirmed the increased risk for older fathers of having infants with de novo achondroplasia.

[Wilson disease: The look of medical staff, patients and family members]. / La enfermedad de Wilson: las diversas perspectivas del profesional sanitario, afectado y familiar.

OBJECTIVE: Wilson disease (WD) is a rare congenital disease that causes hepatic, neurological or lenticular degeneration due to the accumulation of copper. Sometimes it is incapacitating with implications in the quality of life of those affected and their families. The objective of this work was to identify the needs of medical staff and the social and emotional needs of patients with WD and their families. METHODS: A qualitative research was developed in the Valencian Region during 2015-2016, five interviews with medical staff and two focus groups were made, one with family members and another with patients using a script divided into: diagnosis, treatment, health care and quality of life. The information was collected in audio/video and transcribed. An analysis of discourse (professional vs family/affected) determining needs was made. RESULTS: Medical staff need more knowledge about this pathology. Better educational training for them would facilitate the diagnosis. Families and patients need more information about the guidelines for the treatment's administration and foods that should be excluded from the diet. The correct administration of the treatment will allow those affected to improve their quality of life with a total or partial recovery of their symptoms.. CONCLUSIONS: Peru has made significant progress in reducing chronic malnutrition in children, but it still represents a health problem due to high prevalence in the sierra and expansion to jungles districts in 2016. Policies and programs should continue and enhance to avoid the high burden of disease that generates malnutrition in the development of children.

OBJETIVO: La Enfermedad de Wilson (EW) es una patología rara congénita y hereditaria que se produce por acumulación de cobre en el organismo, degeneración crónica hepática, neurológica o lenticular. En ocasiones es incapacitante por lo que influye en la calidad de vida de afectados y familiares. El objetivo de este trabajo fue identificar las necesidades médicas, sociales y emocionales de pacientes y familiares. METODOS: Con metodología cualitativa se realizaron en la Comunitat Valenciana (CV), en 2015-2016, 5 entrevistas a profesionales sanitarios y 2 grupos de discusión, uno con familiares y otro con afectados. Se elaboró un guión estructurado en: diagnóstico, tratamiento, atención sanitaria y calidad de vida. La información se recogió en audio/video, previa autorización y se transcribió literalmente. Se realizó un análisis del discurso (profesionales vs. familiares/afectados) determinando necesidades y demandas concretas. RESULTADOS: Los profesionales se mostraron emocionalmente distantes de las necesidades emocionales de afectados y familiares y consideraron necesario disponer de mayor información para facilitar el diagnóstico precoz. Las familias expresaron preocupación sobre la adherencia al tratamiento, especialmente en adolescentes, y confusión sobre la importancia de seguir una dieta baja en cobre. Los afectados reconocieron tener dudas sobre la funcionalidad de la medicación. Los afectados neurológicamente se sintieron estigmatizados por las secuelas físicas de la enfermedad. CONCLUSIONES: Los sanitarios consideran que tener un mayor conocimiento sobre esta enfermedad facilitaría una detección precoz. Familiares y afectados necesitan indicaciones claras y especificadas sobre las pautas de administración del tratamiento y sobre los alimentos que deben excluir de la dieta.

Epidemiology of septo-optic dysplasia with focus on prevalence and maternal age - A EUROCAT study.

Septo-optic nerve dysplasia is a rare congenital anomaly with optic nerve hypoplasia, pituitary hormone deficiencies and midline developmental defects of the brain. The clinical findings are visual impairment, hypopituitarism and developmental delays. The aim of this study was to report prevalence, associated anomalies, maternal age and other epidemiological factors from a large European population based network of congenital anomaly registries (EUROCAT). Data from 29 full member registries for the years 2005-2014 were included, covering 6.4 million births. There were 99 cases with a diagnosis of septo-optic dysplasia. The prevalence of septo-optic dysplasia in Europe was calculated to lie between 1.9 and 2.5 per 100,000 births after adjusting for potential under-reporting in some registries. The prevalence was highest in babies of mothers aged 20-24 years of age and was significantly higher in UK registries compared with other EUROCAT registries (P = 0.021 in the multilevel model) and the additional risk for younger mothers was significantly greater in the UK compared to the rest of Europe (P = 0.027). The majority of septo-optic dysplasia cases were classified as an isolated cerebral anomaly (N = 76, 77%). Forty percent of diagnoses occurred in fetuses with a prenatal diagnosis. The anomaly may not be visible at birth, which is reflected in that 57% of the postnatal diagnoses occurred over 1 month after birth. This is the first population based study to describe the prevalence of septo-optic dysplasia in Europe. Septo-optic dysplasia shares epidemiological patterns with gastroschisis and this strengthens the hypothesis of vascular disruption being an aetiological factor for septo-optic dysplasia.

Beckwith Wiedemann syndrome: A population-based study on prevalence, prenatal diagnosis, associated anomalies and survival in Europe.

Beckwith Wiedemann syndrome is a complex developmental disorder characterized by somatic overgrowth, macroglossia, abdominal wall defects, neonatal hypoglycemia, and predisposition to embryonal tumors. We present epidemiological and clinical aspects of patients with Beckwith Wiedemann syndrome diagnosed prenatally or in the early years of life, using data from EUROCAT (European Surveillance of Congenital Anomalies) registries. The study population consisted of 371 cases identified between January 1990 and December 2015 in 34 registries from 16 European countries. There were 15 (4.0%) terminations of pregnancy after prenatal detection of severe anomaly/anomalies, 10 fetal deaths (2.7%), and 346 (93.3%) live-births. Twelve (3.6%) of the 330 live-births with available information on survival died in the first week of life, of those eleven (91.6%) were preterm. First-year survival rate was 90.9%. Prematurity was present in 40.6% of males and 33.9% of females. Macrosomia was found in 49.2% and 43.3% of preterm males and females, respectively. Of term newborns, 41.1% of males and 24% of females were macrosomic. Out of 353 cases with known time of diagnosis, 39.9% were suspected prenatally, 36.3% at birth, 7.6% were diagnosed in the first week of life, and 16.2% in the first year of life. The mean gestational age at prenatal diagnosis by obstetric ultrasound was 19.8 ±â€¯6.2 (11-39) gestational weeks. The mean prenatal diagnosis of cases where parents opted for termination of pregnancy was 15.3 ±â€¯2.4 (11-22) gestational weeks, and the mean gestational age at termination was 19.3 ±â€¯4.1 (13-26) gestational weeks. The prenatal detection rate was 64.1% (141/220) with no significant change over time. There were 12.7% of familial cases. The study confirmed the association of assisted reproductive technologies with Beckwith Wiedemann syndrome, as 7.2% (13/181) of patients were conceived by one of the methods of assisted reproductive technologies, which was three times higher compared to the general population of the countries included in the study. Twin pregnancies of undetermined zygosity were recorded in 5.7% (21/365) cases, and were on average three to four times more common than in European countries that participated in the study. The estimated mean prevalence of classical Beckwith Wiedemann syndrome in Europe was 3.8 per 100,000 births or 1:26,000 births.

Beta-Blocker Use in Pregnancy and Risk of Specific Congenital Anomalies: A European Case-Malformed Control Study.

INTRODUCTION: The prevalence of chronic hypertension is increasing in pregnant women. Beta-blockers are among the most prevalent anti-hypertensive agents used in early pregnancy. OBJECTIVE: The objective of this study was to investigate whether first-trimester use of beta-blockers increases the risk of specific congenital anomalies in offspring. METHODS: A population-based case-malformed control study was conducted in 117,122 registrations of congenital anomalies from 17 European Concerted Action on Congenital Anomalies and Twins (EUROCAT) registries participating in EUROmediCAT with data for all or part of the period between 1995 and 2013. Associations previously reported in the literature (signals) were tested and an exploratory analysis was performed to identify new signals. Odds ratios of exposure to any beta-blocker or to a beta-blocker subgroup were calculated for each signal anomaly compared with two control groups (non-chromosomal, non-signal anomalies and chromosomal anomalies). The exploratory analyses were performed for each non-signal anomaly compared with all the other non-signal anomalies. RESULTS: The signals from the literature (congenital heart defects, oral clefts, neural tube defects and hypospadias) were not confirmed. Our exploratory analysis revealed that multi-cystic renal dysplasia had significantly increased odds of occurring after maternal exposure to combined alpha- and beta-blockers (adjusted odds ratio 3.8; 95% confidence interval 1.3-11.0). CONCLUSION: Beta-blocker use in the first trimester of pregnancy was not found to be associated with a higher risk of specific congenital anomalies in the offspring, but a new signal between alpha- and beta-blockers and multi-cystic renal dysplasia was found. Future large epidemiological studies are needed to confirm or refute our findings.
