Esta revisión permitió dar a conocer un nuevo caso de la patología, relacionar las manifestaciones clínicas de la paciente con la literatura y describir nuevos hallazgos que pueden correlacionarse con el síndrome.

Abstract Ellis Van Creveld syndrome is an autosomal recessive disorder, characterized by mutations of the genes ECV and ECV2, which are very important in the osteochondral development. Worldwide, there have been reported around 300 cases that are commonly evidenced in populations where endogamy is typical. It is clinically characterized by bone dystrophies, ectodermal dysplasias, and congenital heart defects; the diagnosis can be confirmed by molecular tests. In the lines below, a case of a patient that suffers from this syndrome, and that was examined in an interdisciplinary way will be presented. This review allows us to show a new case of this pathology, to relate the clinical symptoms of the patient with the existing literature, and to describe new findings that can be correlated with the Ellis Van Creveld condition.

Genética clínica comunitaria: exploración de patología genética en Boyacá, Colombia / Clinical community genetics: exploring genetic disorders in Boyacá, Colombia

RESUMEN Objetivo Explorar la presencia de patología genética sindrómica en el Departamento de Boyacá, mediante un acercamiento de medicina genética comunitaria. Materiales y Métodos Un grupo conformado por genetistas, neurólogo pediátrico y genetista bioquímico, llevó a cabo jornadas clínicas en las cuales se evaluaron pacientes con sospecha de enfermedad genética. Se obtuvieron datos demográficos, epidemiológicos y clínicos y se realizó el cálculo de frecuencias de los mismos. En los centros de referencia visitados se realizaron actividades de capacitación al personal médico. Resultados Se encontraron dos agrupamientos genéticos: MPSIII y Síndrome de Ellis Van Creveld, con incidencias mayores a lo reportado en la literatura, además una alta frecuencia de patologías de herencia autosómica recesiva, así como sospecha de síndromes de microdeleción-microduplicación. Conclusiones Se deben establecer mecanismos no convencionales de atención médica para facilitar el acceso a las comunidades a un diagnóstico y tratamiento adecuados en genética. Se espera que el apoyo brindado a los pacientes, familias y personal asistencial de los hospitales a través de las jornadas clínicas y la capacitación, permitan alcanzar este objetivo y a la vez sea un punto de inicio de procesos de prevención primaria y secundaria.(AU)

ABSTRACT Objectives To explore the incidence of syndromic genetic pathologies in Boyacá, Colombia, through a community genetics approach. Materials and Methods A group made up by different medical specialists (geneticists, a pediatric neurologist, and a biochemical geneticist) developed clinical campaigns, in which patients with clinical suspicion of genetic diseases were involved. Demographic, epidemiological and clinical data were collected, and frequency calculations were made based on the collected data. Several training workshops for health personnel were done in each center visited. Results Two genetic clusters were found: mucopolysaccharidosis type III, and Ellis-Van Creveld Syndrome, both of them with higher incidences than those found in the literature. Also, a high frequency of autosomal recessive diseases was found, as well as microdeletion/microduplication syndromes. Conclusions Conventional mechanisms of medical attention must be established, in order to facilitate the access to an appropriate diagnosis and treatment. This work intended to provide support to patients, families and health care services personnel through the workshops and clinical campaigns, and to become a starting point to develop primary and secondary prevention processes.(AU)

El objetivo es presentar un caso clínico de la forma letal de DTA, enfatizando en el mal pronóstico de la falla respiratoria y la patología asociada.

Ellis-van Creveld syndrome in adulthood: extending the clinical spectrum

Ellis-van Creveld (EvC) syndrome is a rare autosomal recessive malformation disorder. Cardiac defects are observed in about 50% of EvC cases. Surgical data is lacking on the prognosis and life expectancy of EvC patients. Herein, we report the case of a 38-year-old man with EvC syndrome who underwent two surgical corrections for cardiac anomalies. This report supplements the available information on the clinical course of EvC syndrome in older patients.

Ellis van Creveld: reporte de caso / Ellis van Creveld: Case report

Introduction: Ellis-van Creveld (EVC) (OMIM # 225500) syndrome is a rare skeletal dysplasia disorder transmitted by autosomal recessive inheritance. The diagnosis is made based on phenotypic characteristics such as chondrodysplasia, heart defects and polydactyly. The prognosis depends mainly on the severity of the disease, diagnosis and comprehensive management of the condition. Objective: To describe a patient diagnosed with EVC syndrome. Case report: Newborn diagnosed with EVC syndrome who presented dysmorphic facies, shortened long bones, rhizomelic shortening, small hands, brachydactyly, single transverse palmar crease, postaxial polydactyly in the upper limbs, bilateral preaxial polysyndactyly in lower limbs and hypoplastic nails, complex heart defects and narrow thorax. The evolution was unfavorable; the patient died 8 weeks after birth from complications due to heart defects. Conclusions: EVC syndrome is rare and unknown; therefore, it is important to spread its characteristics within the pediatric community, emphasizing that it affects multiple organ systems and requires a multidisciplinary approach to treat individually each patient, to provide genetic and reproductive counseling to couples and to give information regarding child development expectations.

Introducción: El síndrome Ellis-van Creveld (EVC) (OMIM #225500) es una displasia esquelética rara de herencia autosómica recesiva, cuyo diagnóstico se realiza por sus características fenotípicas como la condrodisplasia, cardiopatía y polidactilia. El pronóstico depende fundamentalmente de la severidad de la cardiopatía, al igual que del diagnóstico y manejo integral oportunos. Objetivo: Caracterizar un paciente con diagnóstico clínico de Síndrome de EVC, cuya baja frecuencia dificulta el correcto diagnóstico en pediatría. Caso clínico: Recién nacido con facies dismórfica, extremidades con huesos largos cortos, acortamiento rizomélico, manos pequeñas, braquidactilia, pliegue palmar único, polidactilia post axial en miembros superiores, polisin-dactilia preaxial bilateral en miembros inferiores y uñas hipoplásicas, cardiopatía compleja y tórax estrecho, en el que se concluyó un diagnóstico clínico de EVC. La evolución fue desfavorable, falleciendo a las 8 semanas de nacimiento por complicaciones secundarias a la cardiopatía. Conclusiones: El síndrome de EVC es de baja frecuencia y poco conocido, por lo que es importante difundir sus características en la comunidad pediátrica, haciendo énfasis en que al afectar múltiples sistemas y órganos, requiere un manejo multidisciplinario con el objetivo de intervenir en la patología individualizando cada paciente; además de consejería genética y reproductiva a las parejas, e información de las expectativas del desarrollo del niño.

It is characterized by short-limbed dwarfism, bilateral postaxial hand polydactyl, chondrodysplasia of long bones and ectodermic dysplasia affecting fingernails and teeth. The knowledge of it is essential for early diagnosis and appropriate multidisciplinary management that allows a better quality of life for these patients.

Defecto del canal auriculoventricular, aurícula única y atresia tricuspídea como parte de un caso de síndrome de Ellis-Van Creveld / Atrioventricular canal defect, single atrium and tricuspid atresia as part of a case of Ellis-Van Creveld syndrome

El síndrome de Ellis-Van Creveld (SEVC) o displasia condroectodérmica se debe a una mutación de transmisión autosómica recesiva en el brazo corto del cromosoma 4 y afecta múltiples órganos. Descrito como una tétrada clásica de condrodisplasia, displasia ectodérmica, polidactilia y defectos cardíacos congénitos, sólo se conoce a partir de informes y series de casos. Se describe el caso de un varón de 3 meses, sin antecedentes familiares de importancia, que presentó un cuadro de condrodisplasia, labio superior fusionado al paladar, simpolidactilia posaxial bilateral en las manos, displasia del desarrollo de las caderas, tórax estrecho con costillas cortas y compromiso cardíaco. El presente caso sería la primera comunicación del SEVC en el Perú.

Ellis-Van Creveld Syndrome or chondrectodermal dysplasia is produced by an autosomal recessive inheritance secondary to mutation in the short arm of chromosome 4. The syndrome affects multiple organs. It is described as a clinical tetrad that involves chondrodysplasia, ectodermal dysplasia, polydactyly and congenital heart defects. It is only known from reports and case series. We present a three months old male, without relevant family history, who presented chondrodysplasia, upper lip merged to palate, bilateral sinpolydactyly in the hands, developmental dysplasia of the hip, narrow chest with short ribs, and heart defects. This case is the first report of EVC in Peruvian literature.

Relato de caso: anestesia em paciente portador de distrofia torácica asfixiante: Síndrome de Jeune / Case report: anesthesia in patients with asphyxiating thoracic dystrophy: Jeune Syndrome / Relato de caso: anestesia en paciente portador de distrofia torácica asfixiante: Síndrome de Jeune

JUSTIFICATIVA E OBJETIVOS: Síndrome de Jeune, ou Distrofia Torácica Asfixiante, é uma doença autossômica recessiva. Esta síndrome é caracterizada por uma displasia óssea com variadas anormalidades: torácica, pancreática, cardíaca, hepática, renal e da retina. A idade em que o quadro clínico dos pacientes se apresenta está correlacionada com a gravidade da doença. Esses pacientes apresentam policondrodistrofia com costelas largas, curtas, horizontais e junções costocondrais irregulares levando a uma caixa torácica rígida e reduzida com grau de injúria respiratória variado. RELATO DO CASO: Paciente do sexo masculino, 4 meses, 7 kg, portador de Distrofia Torácica Asfixiante. Apresentava-se intubado e com caixa torácica reduzida. Ecocardiograma: hipertensão pulmonar leve. Tomografia de tórax: hipoplasia pulmonar. Submetido à toracoplastia bilateral e toracotomia sob anestesia geral. Manutenção da anestesia: infusão contínua de sufentanil e sevoflurano. Parâmetros ventilatórios: ventilação mecânica ciclada à pressão. Com a abertura do tórax, houve melhora dos parâmetros ventilatórios e, após o posicionamento da prótese torácica, observou-se limitação ventilatória. Decidiu-se pela diminuição da prótese torácica com consequente melhora da ventilação. CONCLUSÕES: É imprescindível o diagnóstico de todas as anormalidades presentes para o correto manejo anestésico. Foi necessária observação para adequar ventilação pré- e pós-toracotomia/toracoplastia e para manter o paciente hemodinamicamente estável. A forma mais adequada para ventilação mecânica é a ciclada à pressão para vencer a barreira mecânica. No intraoperatório, é desejável manter o pico de pressão inspiratória o mais baixo possível para minimizar o risco de barotrauma, de impedimento do retorno venoso e diminuição do débito cardíaco.

BACKGROUND AND OBJECTIVES: Jeune Syndrome or Asphyxiating Thoracic Dystrophy is a recessive autosomal disease. This syndrome is characterized by a bone dysplasia with varied abnormalities: thoracic, pancreatic, cardiac, hepatic, renal and retinal. Patients' age when the clinical condition is experienced correlates with the disease severity. These patients experience polychondrodystrophy with large, short, horizontal ribs and irregular costochondral junctions resulting in a rigid and reduced thoracic cage with varied respiratory injury level. CASE REPORT: Male patient, 4 months-old, 7 kg, suffering with Asphyxiating Thoracic Dystrophy, intubated and presented with reduced thoracic cage. Echocardiogram: mild pulmonary hypertension. Chest tomography: pulmonary hypoplasia. Patient submitted to bilateral thoracoplasty and thoracotomy with general anesthesia. Anesthesia maintenance: sufentanil e sevoflurane continuous infusion. Ventilation parameters: pressure-cycled mechanical ventilation. Thorax opening provided improvement of the ventilation parameters, but after thoracic prosthesis placement, ventilation was limited. Reduction of the thoracic prosthesis was considered with consequent improvement of ventilation. CONCLUSIONS: Diagnosis of all present abnormalities is essential for the correct anesthetic management. Observation was necessary to adequate pre- and post-thoracotomy/thoracoplasty ventilation and to maintain patient hemodynamically stable. Pressure-cycled mechanical ventilation is the most adequate type of ventilation to overcome the mechanical barrier. In the intraoperative setting, the ideal is to maintain the inspiratory pressure peak as low as possible to minimize the risk of barotrauma, venous return impairment and reduced cardiac output.

Type 1 diabetes in a patient with Ellis-van Creveld syndrome / Diabetes tipo 1 em um paciente com a síndrome de Ellis-van Creveld

CONTEXT: Ellis-van Creveld (EVC) syndrome is a rare autosomal recessive disease characterized by disproportionate short stature, narrow thorax, postaxial polydactyly, nail and tooth abnormalities and congenital heart disease. CASE REPORT: The patient was a 22-year-old Caucasian man, the third child of consanguineous parents. He received the diagnosis of insulin-dependent diabetes mellitus (DM) at 16 years of age, and around one year later, he underwent surgery to correct a partial atrioventricular septal defect. Upon physical examination, at 22 years of age, he presented stature of 145.5 cm (P3), weight of 49 kg (P3), head circumference of 54 cm (P2-50), high palate, absence of one of the lower lateral incisor teeth, narrow shoulders, narrowing of the upper thorax, scoliosis, rhizomelic shortening of the upper limbs, brachydactyly, postaxial polydactyly and clinodactyly of the second and third fingers. The lower limbs showed rhizomelic shortening with significant genu valgum (knock-knee deformity), small feet with postaxial polydactyly, syndactyly between the second and third toes and hallux valgus. Multiple melanocytic nevi were evident on the face, thorax and limbs. At that time, he was using neutral protamine Hagedorn (NPH) insulin, with poorly controlled DM. The clinical findings presented led to the diagnosis of EVC syndrome. Only one case of this syndrome has been described with DM so far. Attention is drawn to the fact that the genes associated with this syndrome are located close to those of the Wolfram syndrome, a condition that leads to early-onset diabetes.

CONTEXTO: A síndrome de Ellis-van Creveld (EVC) é uma doença autossômica recessiva rara, caracterizada por baixa estatura desproporcionada, tórax estreito, polidactilia pós-axial, anormalidades em unhas e dentes e cardiopatia congênita. RELATO DO CASO: O paciente é um rapaz caucasiano de 22 anos, o terceiro filho de pais consanguíneos. Recebeu diagnóstico de diabetes melito (DM) insulino-dependente aos 16 anos, sendo que, cerca de um ano depois, foi submetido a cirurgia cardíaca de correção de defeito de septo atrioventricular parcial. Ao exame físico, aos 22 anos, ele apresentava estatura de 145,5 cm (P3), peso de 49 kg (P3), perímetro cefálico de 54 cm (P2-50), palato alto, ausência de um dos dentes incisivos inferiores laterais, ombros estreitos, estreitamento do tórax superior, escoliose, encurtamento rizomélico dos membros superiores, braquidactilia, polidactilia pós-axial e clinodactilia dos segundo e terceiro dedos. Nos membros inferiores, observava-se encurtamento rizomélico com importante geno valgo (deformidade dos joelhos-batidos), pés pequenos com polidactlia pós-axial, sindactilia entre segundo e terceiro dedos, e háluces valgos. Múltiplos nevos melanocíticos eram evidentes na face, tórax e membros. Neste momento ele está em uso de insulina NPH (neutral protamine Hagedorn), com um controle inadequado do DM. Seus achados clínicos levaram ao diagnóstico de síndrome de EVC. Apenas um caso desta síndrome foi descrito com DM até o momento, sendo que chama a atenção o fato de que os genes associados à síndrome se localizam próximo ao da síndrome de Wolfram, uma condição que cursa com diabetes de início precoce.

Introduction: Ellis van Creveld (EVC) syndrome is a rare genetic disorder which is characterized by a person having short limbs, polydactylia and heart defects; it can be detected prenatally by ultrasound. A case is presented here so that its characteristics, possible differential diagnoses and prognosis can be discussed. Materials and methods: this article presents a case of prenatal diagnosis of EVC by ultrasound which was confirmed shortly after birth. A bibliographic search was made of the Medline via PubMed database; 15 of the 579 articles which were found were reviewed due to their pertinence and topicality. Conclusions: EVC syndrome is a condition which is susceptible to prenatal diagnosis. It should be suspected in cases of mesomelia, polydactyly and cardiac defects. Prognosis mainly depends on the type of cardiac malformation.

Oral abnormalities in the Ellis-van Creveld syndrome.

Ellis-van Creveld (EvC) syndrome is an autosomal recessive disorder, mainly affecting the ectodermal components such as, enamel, nail, and hair. The gene for EvC syndrome is located on chromosome 4p16. Patients with EvC syndrome characteristically presents with congenitally missing teeth, abnormal frenal attachment, microdontia, and hexadactyly.

Ellis van Creveld syndrome with unusual association of essential infantile esotropia

Ellis-van Creveld syndrome is a rare short-limbed disproportionate dwarfism characterized by postaxial polydactyly, several skeletal, oral mucosal and dental anomalies, nail dysplasia and in 50-60% cases of congenital cardiac defects. It is an autosomal recessive disorder with mutations of the EVC1 and EVC2 genes located on chromosome 4p16. Patients with this syndrome usually have a high mortality in early life due to cardiorespiratory problems. We present the case of a six-month-old female infant with Elis-van Creveld syndrome - essential infantile esotropia, which has been infrequently documented in the literature

Ellis-van Creveld syndrome with facial dysmorphic features in an Egyptian child

Ellis-van Creveld syndrome [EVC] is a chondroectodermal dysplasia. The tetrad of cardinal features includes disproportionate dwarfism, bilateral postaxial polydactyl of hands, hidrotic ectodermal dysplasia, and congenital cardiac malformations. This rare condition is inherited as an autosomal recessive trait with variable expression. Mutations of the EVC1 and EVC2 genes, located in a head to head configuration on chromosome 4p16, have been identified as causative. We report a patient with the typical features of the syndrome but with facial dysmorphic features [upward slant of eyes, megalocornea and high forehead], for the first time in the literature

Intraoperative airway obstruction related to tracheostomy tube malposition in a patient with achondroplasia and Jeune's syndrome

A 14 year-old adolescent with achondroplasia and Jeune's syndrome [asphyxiating thoracic dystrophy] presented for cervical spine surgery in the prone position. Due to the need for home mechanical ventilation at night, the patient had a tracheostomy in place. With the first surgical procedure, the cuffed tracheostomy tube was left in place during prone positioning. Difficulties encountered with ventilation through the cuffed tracheostomy tube in the prone position necessitated aborting the case. During three subsequent surgeries, the tracheostomy tube was removed and an armored endotracheal tube was placed through the tracheostomy stoma prior to prone positioning. No further difficulties with ventilation were noted with the subsequent cases. There are currently no guidelines in the medical literature regarding perioperative management of patients with a tracheostomy requiring prone positioning for surgery. The management of such patients is reviewed and possible problems with tracheostomy positioning during prone positioning are explored. Given such issues, we would suggest removal of the tracheostomy tube and placement of an armored endotracheal tube through the stoma during surgical procedures in the prone position

Ellis van creveld syndrome: report of a case and brief literature review

Ellis van Creveld syndrome [EvCS] is a rare autosomal recessive [AR] disorder first described in 1940. The syndrome manifests with several skeletal, oral mucosal and dental anomalies, congenital cardiac defects and nail dysplasia. EvCs should be differentiated from other chondrodystrophies such as achondroplasia and Morquio's syndrome. A nine-year old girl was referred with short stature. In physical examination her height was 105 cm. She had normal intelligence, small teeth, abnormal crown and adontia in mandibular incisors. Other findings included bilateral postaxial polydactyly in hands, narrow thorax, hypoplastic nails in hands and feet and genu valgum. Ellis van Creveld syndrome is a rare autosmal disorder with a high mortality in early life. As the condition is easily diagnosed at birth, early treatment can prevent patients from various complications and undue psychological trauma

Ellis Van Creveld syndrome.

Ellis Van Creveld syndrome is a rare disorder and is a form of short-limbed dwarfism. It is an autosomal recessive disorder characterized by tetrad of disproportionate dwarfism, post-axial polydactyly, ectodermal dysplasia and heart defects. This case report presents a classical case of a seven-year-old boy with Ellis Van Creveld syndrome presented with discrete clinical findings.

Chondroectodermal dysplasia (Ellis van Creveld syndrome): a report of three cases with review of literature.

Chondroectodermal dysplasia is a rare mesenchymal - ectodermal dysplasia first described in 1940 by Richard W.B. Ellis and Simon van Creveld now known as Ellis van Creveld syndrome. It is also known as Mesvectodermal dysplasia. Majority of cases were characteristically seen in one particular inbred population from the Amish community of Lancaster County, Pennsylvania, U.S.A. The syndrome manifests with several skeletal anomalies, oral mucosal and dental anomalies, congenital cardiac defects and nail dysplasia. Ellis van Creveld syndrome may be differentiated from other chondrodystrophies like achondroplasia, chondroplasia punctata, asphyxiating thorasic dystrophy and Morquio's syndrome. The presence of oral mucosal and dental alterations like notching of the lower alveolar process, fusion of the upper lip with gingival mucosal margin, occasional presence of neonatal teeth, oligodontia and conical shape of anterior teeth will confirm the diagnosis of Ellis van Creveld syndrome and hence its importance to dentists.
