RESUMO

In most cases an ectopic ureter is associated with a duplicated renal collecting system while in only a few single systems is found. Bilateral single system ureteral ectopia is even rarer. A 9-year-old girl presented with urinary incontinence. Investigations pointed towards bilateral single system ectopic ureters with ectopic openings into vagina with a hypoplastic bladder. The left ureteric system was tortuous with malrotated and hypoplastic left kidney. A 4 × 2 cm hard calculus was found in the vagina. Right Ureteric reimplantation with left to right uretero-ureterostomy was done with satisfactory postoperative day time continence at 6 months without the need for bladder reconstruction or urinary diversion.

RESUMO

Several recurrent malformation associations affecting the development of the embryo have been described in which a genetic etiology has not been found, including LBWC, MURCS, OAVS, OEIS, POC, VACTERL, referred to here as "recurrent constellations of embryonic malformations" (RCEM). All are characterized by an excess of reported monozygotic discordant twins and lack of familial recurrence. We performed a comprehensive review of published twin data across all six phenotypes to allow a more robust assessment of the association with twinning and potential embryologic timing of a disruptive event. We recorded the type of twinning, any overlapping features of another RCEM, maternal characteristics, and the use of ART. Statistically significant associations included an excess of monozygotic twins and 80% discordance rate for the phenotype across all twins. There was an 18.5% rate of ART and no consistently reported maternal adverse events during pregnancy. We found 24 instances of co-occurrence of two RCEM, suggesting a shared pathogenesis across all RCEM phenotypes. We hypothesize the following timing for RCEM phenotypes from the earliest perturbation in development to the latest: LBWC, POC, OEIS, VACTERL, OAVS, then MURCS. The RCEM group of conditions should be considered a spectrum that could be studied as a group.

RESUMO

The presence of body wall closing defects (abdominoschisis and thoracoabdominoschisis) in combination with other congenital malformations was studied in the pig (Sus scrofa domesticus). After clinical examination and literature review, body wall defects with multiple congenital anomalies in eight pigs were described, and classified using anatomical and embryological criteria. Several BSA presentations were identified and classified as follows: (a) BSA Type I: fetus with spinal and UC defects, thoracoabdominoschisis, anal atresia and/or other internal organs structural defects, and structural limb defects; (b) BSA Type II: fetus with spinal and UC defects, thoracoabdominoschisis, anal atresia and/or other internal organs structural defects, and nonstructural limb defects; (c) BSA Type III: fetus with spinal and UC defects, abdominoschisis, anal atresia and/or other internal organs structural defects, and structural limb defects; and (d) BSA Type IV: fetus with spinal and UC defects, abdominoschisis, anal atresia and/or other internal organs structural defects, and nonstructural limb defects. Two types of LBWC were differentiated: LBWC Type I: characterized by thoracoabdominoschisis and structural limb defects, and LBWC Type II: characterized by abdominoschisis and structural limb defects, corresponding to BSA type I and type III. This is the first report on BSA and LBWC in the pig.

RESUMO

Chromosome 16 is one of the most gene-rich chromosomes of our genome, and 10% of its sequence consists of segmental duplications, which give instability and predisposition to rearrangement by the recurrent mechanism of non-allelic homologous recombination. Microarray technologies have allowed for the analysis of copy number variations (CNVs) that can contribute to the risk of developing complex diseases. By array comparative genomic hybridization (CGH) screening of 1476 patients, we detected 27 cases with CNVs on chromosome 16. We identified four smallest regions of overlapping (SROs): one at 16p13.11 was found in seven patients; one at 16p12.2 was found in four patients; two close SROs at 16p11.2 were found in twelve patients; finally, six patients were found with atypical rearrangements. Although phenotypic variability was observed, we identified a male bias for Childhood Apraxia of Speech associated to 16p11.2 microdeletions. We also reported an elevated frequency of second-site genomic alterations, supporting the model of the second hit to explain the clinical variability associated with CNV syndromes. Our goal was to contribute to the building of a chromosome 16 disease-map based on disease susceptibility regions. The role of the CNVs of chromosome 16 was increasingly made clear in the determination of developmental delay. We also found that in some cases a second-site CNV could explain the phenotypic heterogeneity by a simple additive effect or a pejorative synergistic effect.

RESUMO

Oesophageal atresia causes a dysplasia of the oesophagus with or without a connection to the adjoining trachea. Prenatal ultrasound results are not specific enough to confirm a suspected diagnosis. In addition to polyhydramnios and a small or absent stomach, the so-called "pouch sign" reinforces the suspected diagnosis. An MRI increases the prenatal detection rate. Due to the lack of reliable sonografic markers, ultrasonic testing is advised during pregnancy. Particularly, further causes for the polyhydramnios should be categorically excluded. Postnatally, children present with classic symptoms. Surgical treatment results in a very high quality of life and a very good prognosis. Nevertheless lifelong monitoring and follow-up of the patient is required.

RESUMO

Background Silver-Russell syndrome (SRS) is characterized by growth retardation and variable features including macrocephaly, body asymmetry, and genital manifestations such as cryptorchidism in 46,XY patients. Case presentation The patient was born at 39 weeks with a birth weight of 1344 g. Subtle clitoromegaly warranted a thorough evaluation, which disclosed 46,XY karyotype, bilateral undescended testes, and a rudimentary uterus. Because of severe under-virilization, the patient was assigned as female. Failure to thrive, macrocephaly, and body asymmetry led to the diagnosis of SRS, confirmed by marked hypomethylation of H19/IGF2 intergenic differentially methylated region (IG-DMR). From age 9 years, progressive virilization occurred, which necessitated luteinizing hormone-releasing hormone analog (LHRHa) treatment. Gonadal resection at 15 years revealed immature testes with mostly Sertoli-cell-only tubules. Panel analysis for 46,XY-differences of sex development (DSD) failed to detect any pathogenic variants. Conclusions This is the second reported case of molecularly proven 46,XY SRS accompanied by severe under-virilization. SRS should be included in the differential diagnosis of 46,XY-DSD.

RESUMO

Nablus syndrome was first described by the late Ahmad Teebi in 2000, and 13 individuals have been reported to date. Nablus syndrome can be clinically diagnosed based on striking facial features, including tight glistening skin with reduced facial expression, blepharophimosis, telecanthus, bulky nasal tip, abnormal external ear architecture, upswept frontal hairline, and sparse eyebrows. However, the precise genetic etiology for this rare condition remains elusive. Comparative microarray analyses of individuals with Nablus syndrome (including two mother-son pairs) reveal an overlapping 8q22.1 microdeletion, with a minimal critical region of 1.84 Mb (94.43-96.27 Mb). Whereas this deletion is present in all affected individuals, 13 individuals without Nablus syndrome (including two mother-child pairs) also have the 8q22.1 microdeletion that partially or fully overlaps the minimal critical region. Thus, the 8q22.1 microdeletion is necessary but not sufficient to cause the clinical features characteristic of Nablus syndrome. We discuss possible explanations for Nablus syndrome, including one-locus, two-locus, epigenetic, and environmental mechanisms. We performed exome sequencing for five individuals with Nablus syndrome. Although we failed to identify any deleterious rare coding variants in the critical region that were shared between individuals, we did identify one common SNP in an intronic region that was shared. Clearly, unraveling the genetic mechanism(s) of Nablus syndrome will require additional investigation, including genomic and RNA sequencing of a larger cohort of affected individuals. If successful, it will provide important insights into fundamental concepts such as variable expressivity, incomplete penetrance, and complex disease relevant to both Mendelian and non-Mendelian disorders.

RESUMO

BACK GROUND: Lung agenesis is a rare congenital anomaly. The main etiology of the disease is unknown whereas genetic, iatrogenic and viral factors as well as vitamin A deficiency during early pregnancy may result in developmental failure of primitive lung bud causing unilateral pulmonary agenesis. Affected patients usually present with variable respiratory symptoms and recurrent chest infection at any age. Plain film demonstrates opaque unilateral lung while chest CT scan can definitely diagnosis the disease. The anomaly has three types. Type I is pulmonary agenesis, type II is called pulmonary aplasia and type III is pulmonary hypoplasia. CASES' PRESENTATION: Six patients with main complaint of dyspnea underwent contrast enhanced chest CT in radiology department of French Medical Institute for Mothers and children, Kabul and were diagnosed lung agenesis. Three patients were categorized as type II pulmonary agenesis (aplasia). Two patients, three months old boy and a seven year- old girl demonstrated right lung aplasia. Another patient boy of eighteen years old presented with left lung aplasia. Two boys of four and seven months of age were classified as type I pulmonary agenesis (agenesis). A boy of one year old was diagnosed pulmonary agenesis type III, right lung hypoplasia. CONCLUSION: Six patients were diagnosed with pulmonary agenesis by Chest CT scan. The clinicians should consider possibility of congenital pulmonary agenesis in dyspneic patients with opaque unilateral hemithorax in plain film.

RESUMO

Epidermal nevi are hamartomatous lesions derived from the epidermis and/or adnexal structures of the skin; they have traditionally been classified according to their morphology. New variants have been described in recent years and advances in genetics have contributed to better characterization of these lesions and an improved understanding of their relationship with certain extracutaneous manifestations. In the first part of this review article, we will look at nevi derived specifically from the epidermis and associated syndromes.

RESUMO

BACKGROUND: Vascular anomalies are a diagnostic and therapeutic challenge. They require dedicated interdisciplinary management. Optimal patient care relies on integral medical evaluation and a classification system established by experts in the field, to provide a better understanding of these complex vascular entities. METHOD: A dedicated classification system according to the International Society for the Study of Vascular Anomalies (ISSVA) and the German Interdisciplinary Society of Vascular Anomalies (DiGGefA) is presented. The vast spectrum of diagnostic modalities, ranging from ultrasound with color Doppler, conventional X-ray, CT with 4 D imaging and MRI as well as catheter angiography for appropriate assessment is discussed. RESULTS: Congenital vascular anomalies are comprised of vascular tumors, based on endothelial cell proliferation and vascular malformations with underlying mesenchymal and angiogenetic disorder. Vascular tumors tend to regress with patient's age, vascular malformations increase in size and are subdivided into capillary, venous, lymphatic, arterio-venous and combined malformations, depending on their dominant vasculature. According to their appearance, venous malformations are the most common representative of vascular anomalies (70 %), followed by lymphatic malformations (12 %), arterio-venous malformations (8 %), combined malformation syndromes (6 %) and capillary malformations (4 %). CONCLUSION: The aim is to provide an overview of the current classification system and diagnostic characterization of vascular anomalies in order to facilitate interdisciplinary management of vascular anomalies. KEY POINTS: · Vascular anomalies are comprised of vascular tumors and vascular malformations, both considered to be rare diseases.. · Appropriate treatment depends on correct classification and diagnosis of vascular anomalies, which is based on established national and international classification systems, recommendations and guidelines.. · In the classification, diagnosis and treatment of congenital vascular anomalies, radiology plays an integral part in patient management..

RESUMO

OBJECTIVES: The aim of this report is to describe the orofacial manifestations and dental management of a girl with Sanjad-Sakati syndrome. CLINICAL PRESENTATION AND INTERVENTION: The facial features included microcephaly, thin lips, beaked nose, low set ears, and a retrognathic mandible. An oral examination revealed oligodontia/hypodontia, small dental arches, a high arched palate, and a deep overbite and increased overjet. Oral rehabilitation involved full coverage prosthetic crowns on the upper central incisors, stainless steel crowns on the lower molars, and removable partial prostheses to replace missing teeth. CONCLUSION: Recognition of orofacial features might help in the diagnosis of Sanjad-Sakati syndrome. Dental management of affected patients might be complicated by intellectual, neurological, and endocrine abnormalities.

RESUMO

Brainstem dysgenesis designates all those patients with congenital dysfunction of cranial nerves and muscle tone due to prenatal lesions or malformations of the brainstem. This generic term has the advantage over the eponyms Moebius 'expanded' or 'unrestricted', Robin, Cogan or Carey-Fineman-Ziter syndromes in that it has a less restrictive view and provides a frame work that enables a systematic approach to diagnosis and research of most developmental disorders involving the brainstem. The review of the literature and our experience shows that infants with a predominant rombencephalic involvement are due to brainstem prenatal disruptive vascular accidents, while cases with midbrain and cerebellar involvement and widespread malformative syndromes have most likely an underlying genetic cause. Due to phenotypic heterogeneity associated with brainstem dysgenesis, it is crucial to evaluate each case individually and to establish a specific therapeutic plan. Intervention programs should start soon after diagnosis and directed to improve functions needed for daily life activities. Even though the prognosis of patients with brainstem dysgenesis due to prenatal destructive lesions depends on the magnitude of the vascular territory involved, in most patients with brainstem dysgenesis, the prognosis is better than the initial clinical manifestations would indicate.


TITLE: Disgenesia troncoencefalica: mas alla del sindrome de Moebius.El termino 'disgenesia troncoencefalica' se aplica a los pacientes que presentan afectacion congenita de multiples pares craneales, hipotonia muscular y signos leves de afectacion de la via piramidal. Este termino es ventajoso respecto al uso de eponimos tales como Moebius, Robin, Cogan y Carey-Fineman-Ziter, ya que es menos restrictivo y ofrece un nuevo enfoque para comprender las causas y su patogenia, asi como para mejorar el tratamiento de este grupo de alteraciones del desarrollo que afectan exclusiva o predominantemente al tronco del encefalo. La revision de la bibliografia y nuestra experiencia muestran que la mayoria de los casos con afectacion selectiva del rombencefalo se deben a lesiones disruptivas prenatales, mientras que en los casos con afectacion del mesencefalo y el cerebelo, asi como en los sindromes polimalformativos con afectacion destacada del troncoencefalo, la topografia de las lesiones es mas difusa y menos especifica, y la causa hereditaria, mas probable. Debido a la amplia heterogeneidad fenotipica asociada a la disgenesia troncoencefalica, es esencial realizar una evaluacion individualizada y establecer un plan de tratamiento especifico. Los programas de rehabilitacion deben comenzar poco despues del diagnostico y centrarse en mejorar las habilidades motoras, dotando al paciente de las herramientas necesarias para afrontar las necesidades diarias en funcion de la morbilidad asociada. Aunque el pronostico de la disgenesia troncoencefalica secundaria a lesiones disruptivas depende de la localizacion y la extension del territorio vascular afectado, en general, el pronostico de los pacientes con disgenesia troncoencefalica es mejor de lo que las manifestaciones clinicas iniciales harian suponer.

RESUMO

INTRODUCTION: Craniofacial clefts belong to the most disfiguring and rare congenital malformations of the face and among these, orbito-facial clefts constitute approximately 0.22 % of the cases with Tessier cleft number 5 being the least common. Our aim was to define the phenotypic spectrum for this subgroup to improve clinical management. METHODS: Our study group consisted of four patients which were treated at two different cleft centers. Retrospective chart review and anatomical analysis were conducted for each patient based on clinical evaluation and imaging studies. Morphological anomalies including soft tissue, bone and oral components were recorded. RESULTS: Based on our analysis and literature review, we could define two subtypes of Tessier facial cleft number 5. (1) Medial clefts are the more severe subtype, creating a significant soft tissue and bone defect that runs vertically, through the eyelid, infraorbital rim, maxillary sinus and cheek. They have the poorer esthetic and functional prognosis, due to orbital dystopia and absence of lower eyelid. (2) Lateral clefts are a less severe subtype characterized by the presence of a vertical furrow of the cheek running laterally to the maxillary sinus. CONCLUSIONS: We identified two subtypes of facial cleft number 5 which require an individualized surgical management.

RESUMO

STUDY DESIGN: This is a retrospective cohort study. BACKGROUND: Hemimetameric segmental shift (HMMS) is defined as a hemivertebral deformation in which 2 or more hemivertebrae exist on both sides of the spine and are separated by at least 1 normal vertebra. Reports of HMMS are rare and based on simple anterior x-ray images. No reports have used 3-dimensional computed tomography (3D-CT) to analyze both the anterior and posterior elements. The objective of this study was to analyze the morphology and clinical features of HMMS 3 dimensionally. METHODS: HMMS was confirmed in 32 (6.6%, 16 males and 16 females) of 483 patients diagnosed with congenital scoliosis at the study institution between 1998 and 2013. The average age at the first visit was 6 years and 3 months. 3D-CT imaging was performed for 30 patients older than 2 years (average age: 9 y and 8 mo) and used to classify cases according to posterior elements. RESULTS: With regard to the number of hemivertebrae present, 21 patients had 2 hemivertebrae, 7 patients had 3 hemivertebrae, and 2 patients had 4 hemivertebrae. Patients with 2 hemivertebrae predominantly had hemivertebrae in the thoracolumbar spine. Patients were classified into 2 categories: malformation existing at an equal level in anterior and posterior sides (unison HMMS) and malformation existing at nonequal levels (discordant HMMS). Nine patients had unison HMMS and all of them had 2 hemivertebrae (average: 4.6 vertebrae). Twenty-one patients had discordant HMMS, with 12 having 2 hemivertebrae, 7 having 3 hemivertebrae, and 2 having 4 hemivertebrae. CONCLUSIONS: Through 3D-CT analysis, HMMS was categorized as unison or discordant. Discordant HMMS was observed in 21 of 30 (70%) patients and in all patients with >3 hemivertebrae. Diagnosing HMMS, whether unison or discordant, is clinically important and should be done with careful analysis of bone models and/or radiologic images to determine the correct spinal levels. LEVEL OF EVIDENCE: Level IV-diagnostic study.

RESUMO

BACKGROUND: It is estimated that 20 to 30% of infants with birth defects have two or more birth defects. Among these infants with multiple congenital anomalies (MCA), co-occurring anomalies may represent either chance (i.e., unrelated etiologies) or pathogenically associated patterns of anomalies. While some MCA patterns have been recognized and described (e.g., known syndromes), others have not been identified or characterized. Elucidating these patterns may result in a better understanding of the etiologies of these MCAs. METHODS: This article reviews the literature with regard to analytic methods that have been used to evaluate patterns of MCAs, in particular those using birth defect registry data. RESULTS: A popular method for MCA assessment involves a comparison of the observed to expected ratio for a given combination of MCAs, or one of several modified versions of this comparison. Other methods include use of numerical taxonomy or other clustering techniques, multiple regression analysis, and log-linear analysis. Advantages and disadvantages of these approaches, as well as specific applications, were outlined. CONCLUSION: Despite the availability of multiple analytic approaches, relatively few MCA combinations have been assessed. The availability of large birth defects registries and computing resources that allow for automated, big data strategies for prioritizing MCA patterns may provide for new avenues for better understanding co-occurrence of birth defects. Thus, the selection of an analytic approach may depend on several considerations. Birth Defects Research 110:5-11, 2018. © 2017 Wiley Periodicals, Inc.

RESUMO

INTRODUCTION: The term 'RASopathies' covers a series of diseases that present mutations in the genes that code for the proteins of the RAS/MAPK pathway. These diseases include neurofibromatosis type 1, Noonan syndrome, Legius syndrome, LEOPARD syndrome, Costello syndrome and cardiofaciocutaneous syndrome. Involvement of the RAS/MAPK pathway not only increases predisposition to develop tumours, but also determines the presence of phenotypic anomalies and alterations in learning processes. AIM: To review the use of therapeutic strategies with mechanisms that have a selective action on RASopathies. DEVELOPMENT: The fact that the RAS pathway is involved in a third of all neoplasms has led to the development and study of different drugs at this level. Some of these pharmaceutical agents have been tested in RASopathies, mainly in neurofibromatosis type 1. Here we analyse the use of different antitarget treatments: drugs that act on the membrane receptors, such as tyrosine kinase inhibitors, in the mTOR pathway or MEK inhibitors. These latter have shown potential benefits in recent studies conducted on different RASopathies. CONCLUSIONS: Today, thanks to the results from the first studies conducted with MEK inhibitor based mainly on animal models, a number of promising clinical trials are being carried out.


TITLE: Actualizacion del tratamiento de las rasopatias.Introduccion. El termino 'rasopatias' agrupa una serie de enfermedades que presentan mutaciones en genes que codifican las proteinas de la via RAS/MAPK. Estas enfermedades incluyen la neurofibromatosis de tipo 1, el sindrome de Noonan, el sindrome de Legius, el sindrome LEOPARD, el sindrome de Costello y el sindrome cardiofaciocutaneo. La afectacion de la via RAS/MAPK no solo aumenta la predisposicion a desarrollar tumores, sino que tambien determina la presencia de anomalias fenotipicas y alteraciones en los procesos de aprendizaje. Objetivo. Revisar el papel del uso de estrategias terapeuticas con mecanismos de accion selectivo en las rasopatias. Desarrollo. El hecho de que la via RAS participe en un tercio de las neoplasias ha motivado el desarrollo y el estudio de distintos farmacos a este nivel. Algunos de estos farmacos han sido probados en las rasopatias, principalmente en la neurofibromatosis de tipo 1. Analizamos el uso de distintos tratamientos antidiana: farmacos que actuan en los receptores de membrana, como los inhibidores de la tirosincinasa, en la via mTOR o los inhibidores de MEK. Existe un potencial beneficio de estos ultimos en estudios recientes realizados en distintas rasopatias. Conclusiones. Actualmente, gracias a los resultados de los primeros trabajos desarrollados con inhibidor de MEK basados principalmente en modelos animales, se estan realizando multiples ensayos clinicos prometedores.

RESUMO

Conotruncal heart defects (CTDs) are severe malformations of outflow tract with heterogeneous morphology. Several missense variants of CITED2 have been identified to cause CTDs in recent researches. In this study, we screened the coding regions of CITED2 in 605 Chinese children with CTDs and found two possible pathogenic mutant sites: p.Q117L and p.T257A, both located in the conserved regions of CITED2. Then, we investigated the biological and functional alterations of them. Western blotting showed low level of protein expression of mutant Q117 and T257A compared with wild-type CITED2. Dual-luciferase reporter assay demonstrated that mutant Q117 and T257A decreased the ability of CITED2 to modulate the expression of paired-like homeodomain transcription factor 2 gamma (PITX2C), which are closely related to cardiac growth and left-right patterning. Meanwhile, T257A also exhibited impaired ability to mediate vascular endothelial growth factor expression, another gene closely associated with the normal development of cardiovascular system. Three-dimensional molecular conformation showed reduced hydrogen bond between Asp254 and mutant Thr257, indicating the weakened stability and binding ability of CITED2. All these results suggest that CITED2 mutations in conserved regions lead to disease-causing biological and functional changes and may contribute to the occurrence of CTDs.

RESUMO

Importance: CHARGE syndrome refers to a syndrome involving coloboma, heart defects, atresia choanae, retardation of growth and development, genitourinary disorders, and ear anomalies. However, Verloes revised the characteristics of CHARGE syndrome in 2005 to define this syndrome more broadly. Deficiency of the semicircular canals is now a major criterion for CHARGE syndrome. Objective: To characterize patients with CHARGE syndrome at our center using Verloes' criteria and to reevaluate the nomenclature for this condition. Design, Setting, and Participants: We performed a medical chart review of patients with CHARGE syndrome and reviewed their temporal bone imaging studies at a tertiary care children's hospital affiliated with Washington University in St Louis. Two authors independently reviewed each imaging study (A.W. and K.H.). Radiologic studies, physical findings, genetic tests, and other diagnostic tests were included. Patients with no temporal bone imaging studies were excluded. Results: Eighteen children were included in this study; 13 children (72%) were male, and the mean (median; range) age of patients at the time of inner ear imaging studies was 2 years (4.5 years; 8 months to 8 years). Coloboma was present in 13 patients (72%) and choanal atresia in 5 (28%); semicircular canal anomalies were present in all patients. Additionally, 13 patients (72%) were diagnosed as having hindbrain anomalies, 17 (94%) as having endocrine disorders, 17 (94%) as having mediastinal organ malformations, and all as having middle or external ear abnormalities and development delay. Cleft lip and cleft palate were found in 6 of 14 patients (43%) who did not have choanal atresia. We tested 16 patients for mutations in the CHD7 gene; 10 were positive (63%) for mutations, 4 (25%) were negative, and 2 (13%) were inconclusive. Conclusions and Relevance: Semicircular canal anomalies were the most consistent finding in our patients with CHARGE syndrome. Given the high prevalence of semicircular canal hypoplasia and importance of imaging for diagnosing CHARGE syndrome, we propose changing the term CHARGE syndrome to 3C syndrome to emphasize the importance of the semicircular canals and to recall the 3 major criteria for diagnosis: coloboma, choanal atresia, and semicircular canal anomaly. The nomenclature would also reference the 3 semicircular canals in each ear. This new name for CHARGE syndrome would provide a mnemonic and focus the disease on the most important clinical criteria for diagnosis.

RESUMO

INTRODUCTION: The WHO has launched a common classification for disabilities in children, the International Classification of Functioning, Disability and Health, Child and Youth Version (ICF-CY). We wanted to determine whether cat-egories of the environmental (e) and the body functions (b) components of the classification could address environmental needs in children with different disorders and various disability severities. METHODS: A set of 16 e categories and 47 b categories were selected and worded to best enable parents to describe children's everyday support needs and environmental influences through interviews in their own homes. RESULTS: Of the 367 invited parents, 332 (90.5%) participated, providing data on children with spina bifida, spinal muscular atrophy, muscular disorders, cerebral palsy, visual impairments, hearing impairments, mental disability and disabilities following brain tumour treatment. The mean age of children across disabilities was 9.4 years (range: 1.0-15.9). The mean e code score was 35.7 (range: 4.0-64.0), and the mean b code score was 32.2 (range: 0.0-159.0). The most urgent needs as detected by qualifier 4 environmental categories scores were common among children with complex disorders and issues related to health professionals, legal services and health services. CONCLUSIONS: Parents understand the environmental and body function components in a meaningful manner and the codes seem to be valid. Special emphasis should be given to environmental issues for children with more complex disabilities. There was no correlation between the severity of a disability and environmental issues, indicating that each child's needs were basically met, irrespective of disability severity.
