Oculo-facio-cardio-dental syndrome caused by BCOR gene mutations: a case report / 中国当代儿科杂志

A full-term female infant was admitted at 5 hours after birth due to heart malformations found during the fetal period and cyanosis once after birth. Mmultiple malformations of eyes, face, limbs, and heart were noted. The whole-exome sequencing revealed a pathogenic heterozygous mutation, c.2428C>T(p.Arg810*), in the BCOR gene. The infant was then diagnosed with oculo-facio-cardio-dental syndrome. He received assisted ventilation to improve oxygenation and nutritional support during hospitalization. Right ventricular double outlet correction was performed 1 month after birth. Ocular lesions were followed up and scheduled for elective surgery. The possibility of oculo-facio-cardio-dental syndrome should be considered for neonates with multiple malformations of eyes, face, and heart, and genetic testing should be performed as early as possible to confirm the diagnosis; meanwhile, active ophthalmic and cardiovascular symptomatic treatment should be given to improve the prognosis.

Anomalías congénitas y comorbilidad en neonatos con Síndrome de Down / Congenital anomalies and comorbidities in neonates with Down Syndrome

INTRODUCCIÓN: El Síndrome de Down se presenta en 2,5 de 1.000 recién nacidos vivos chilenos. Presentan más anomalías congénitas y comorbilidades que la población general, aumentando su tasa de hospitalización. OBJETIVO: Describir las anomalías congénitas y comorbilidades de neonatos con Síndrome de Down nacidos y/u hospitalizados en la década 2008-2018. PACIENTES Y MÉTODO: Retrospectiva mente se revisaron registros de los pacientes nacidos y/u hospitalizados dentro de sus 28 días de vida entre el 1 de enero de 2008 y el 31 de diciembre de 2018. Para cada paciente se consignó: edad materna, antecedentes familiares de Síndrome de Down, antecedentes pre y perinatales y resultado de estudio genético. Se consignó la edad al ingreso, el motivo principal de ingreso, comorbilidades, días de hospitalización y fallecimiento. Se excluyeron dos pacientes con más del 50% de ficha in completa. Se exploraron asociaciones entre morbilidades, anomalías y fallecimiento. RESULTADOS: 140 de 79.506 (0,2%) recién nacidos vivos fueron diagnosticados con Síndrome de Down en el período neonatal. 24,7% fueron prematuros y 26,4% tuvieron bajo peso para su edad gestacional. Los porcentajes de morbilidad y hospitalización fueron 83,6% y 90%. La principal causa de ingreso fue la poliglobulia, y la más frecuente hiperbilirrubinemia. Fallecieron 4 pacientes (2,9%) y 70,7% presentó alguna una anomalía congénita, principalmente cardíaca. La mediana de edad materna fue de 36 años y 57,1% tenía 35 años o más. CONCLUSIONES: Esta investigación aporta información relevante para optimizar el manejo perinatal y el seguimiento de los pacientes con Síndrome de Down.

INTRODUCTION: In Chile, Down syndrome has a prevalence of 2.5 in 1,000 live births. These patients present more congenital anomalies and comorbidities than the general population, increasing their hospitaliza tion rate. OBJECTIVE: To describe congenital anomalies and comorbidities of neonates with Down syndrome born and/or hospitalized between 2008 and 2018. PATIENTS AND METHOD: We conducted a retrospective review of patient's medical records born and/or hospitalized during their first 28 days of life between January 1st, 2008, and December 31st, 2018. For each patient, we recorded maternal age, familiar cases of Down Syndrome, pre and perinatal history, genetic study result, as well as age at admission, reason for hospitalization, comorbidities, length of stay, and death. Two patients that had more than 50% of incomplete medical records were excluded. We studied the associations between comorbidities, congenital anomalies, and death. RESULTS: 140 in 79,506 newborns (0.2%) were diagnosed at our center with Down Syndrome in their neonatal period. 24.7% were born preterm and 26.4% had low birth weight for gestational age. Morbidities and hospitalizations were present in 83.6% and 90%, of the study population, respectively. The main reason for hospitalization was polycythemia and the most frequent was hyperbilirubinemia. Four patients died (2.9%) and 70.7% presented at least one congenital anomaly, mainly heart disease. Median maternal age was 36 years and 57.1% of mothers were aged 35 or older. CONCLUSIONS: This cohort of patients with Down Syndrome provides important information for the optimization of their perinatal management and follow-up.

Sindrome de Marshall- Smith en mujer adulta: nuevos retos en anticoncepción / Marshall-Smith syndrome in an adult woman: new challenges in contraception

Se presenta el caso de una mujer de 38 años con Síndrome de Marshall-Smith. Se trata de una enfermedad rara de etiología desconocida, cuyas características incluyen anomalías craneofaciales, maduración ósea acelerada, alteraciones en el desarrollo neurológico y en las vías respiratorias con compromiso de la vía aérea y escasa supervivencia a largo plazo debido a problemas respiratorios. Sin embargo, los avances en el soporte respiratorio han permitido que algunos pacientes lleguen a la etapa adulta. Nuestra paciente, sin retraso intelectual ni psicomotor, solicita método anticonceptivo. Los pacientes con enfermedades raras necesitan ser atendidos con especial dedicación intentando reducir al mínimo la transmisión genética de dichas entidades, y mejorando al máximo su calidad de vida. Se ofrece un método anticonceptivo reversible de larga duración, sin riesgos para la evolución de su patología respiratoria, y atendiendo a los criterios medicos de elegibilidad de método anticonceptivo de la OMS, se indica la utilización de un implante subdérmico de etonogestrel. Con un perfil de seguridad y farmacocinética equivalente a los métodos de solo gestágeno y mayor comodidad.

A 38-year-old female patient with a history of Marshall-Smith syndrome is reported. It is a rare congenital disorder of unknown aetiology, which features include craneo facial dysmorphism, accelerated bone maturation, neurodevelopmental abnormalities, and upper and lower airways compromise. Long term survival is a problem due to respiratory complications, but it has decreased since airway support has improved, and that allows survival into adulthood. Our patient has neither intelectual nor psychomotor delay, so she asks for contraception method. As a rare genetic condition it needs to be attended with special consideration in order to reduce the disorder's transmission and to increase the life's quality of patients. A secure contraception method should be offered with no risk at all, attending to medical elegibility criteria for contraception use. We considered progestogen-only options and the patient's choice was etonogestrel subcutaneous implant.

CRIANÇAS COM MÚLTIPLAS MALFORMAÇÕES CONGÊNITAS: QUAIS SÃO OS LIMITES ENTRE OBSTINAÇÃO TERAPÊUTICA E TRATAMENTO DE BENEFÍCIO DUVIDOSO? / CHILDREN WITH MULTIPLE CONGENITAL DEFECTS: WHAT ARE THE LIMITS BETWEEN THERAPEUTIC OBSTINACY AND THE TREATMENT OF UNCERTAIN BENEFIT?

RESUMO Objetivo: A abordagem terapêutica de crianças com múltiplas malformações inclui muitos dilemas, tornando difícil diferenciar um tratamento de benefício duvidoso da obstinação terapêutica. O objetivo deste artigo foi destacar as possíveis fontes de incerteza no processo de tomada de decisão para esse grupo de crianças. Descrição do caso: Lactente de 11 meses de idade, que nasceu com múltiplas malformações congênitas e foi abandonado por seus pais, nunca recebeu alta hospitalar. Ele tem cardiopatia congênita cianótica, estenose do brônquio fonte esquerdo e imperfuração anal. Passou por muitos procedimentos cirúrgicos e permanece sob suporte tecnológico. A correção total do defeito cardíaco parece improvável, e todas as tentativas de desmame do ventilador falharam. Comentários: As duas principais fontes de incerteza no processo de tomada de decisão para crianças com múltiplos defeitos congênitos estão relacionadas ao prognóstico incerto. Dados empíricos escassos são por conta das múltiplas possibilidades de envolvimento (anatômico ou funcional) de órgãos, com poucos casos semelhantes descritos na literatura. O prognóstico é também imprevisível para a evolução da capacidade cognitiva e para o desenvolvimento de outros órgãos. Outra fonte de incertezas é como qualificar uma vida como valendo a pena ser vivida, ponderando custos e benefícios. A quarta fonte de incerteza é quem tem a decisão: os médicos ou os pais? Finalmente, se um tratamento é definido como fútil, então, como limitar o suporte? Na ausência de um método universal para essa tomada de decisão, ficamos com a responsabilidade dos médicos em desenvolver suas habilidades de percepção das necessidades dos pacientes e dos valores familiares.

ABSTRACT Objective: Therapeutic approach of children with multiple malformations poses many dilemmas, making it difficult to build a line between the treatment of uncertain benefit and therapeutic obstinacy. The aim of this paper was to highlight possible sources of uncertainty in the decision-making process, for this group of children. Case description: An 11-month-old boy, born with multiple birth defects and abandoned by his parents, has never been discharged home. He has complex congenital heart disease, main left bronchus stenosis and imperforate anus. He is under technological support and has gone through many surgical procedures. The complete correction of the cardiac defect seems unlikely, and every attempt to wean the ventilator has failed. Comments: The first two main sources of uncertainty in the management of children with multiple birth defects are related to an uncertain prognosis. There is a lack of empirical data, due to the multiple possibilities of anatomic or functional organ involvement, with few similar cases described. Prognosis is also unpredictable for neuro-developmental evolution, as well as the capacity for the development and regeneration of other organs. Another source of uncertainty is how to qualify the present and future life as worth living, by weighing the costs and benefits. The fourth source of uncertainty is who has the decision: physicians or parents? Finally, if a treatment is defined futile then, how to limit support? No single framework exists to help these delicate decision-making processes. We propose, then, that physicians should be committed to develop their own perception skills in order to understand patient’s manifestations of needs and family values.

Síndrome de hipoplasia femoral y facies inusual: reporte de un caso / Femoral hypoplasia-unusual facies syndrome: A case report

Introducción: El síndrome de hipoplasia femoral y facies inusual es una enfermedad rara con expresividad hereditaria variable, aunque se han reportado casos con un patrón autosómico dominante. Afecta particularmente las estructuras de la cara asociado a hipoplasia de fémur. Si bien su etiología no ha sido bien identificada, se ha asociado con diabetes materna, exposición a drogas, infecciones virales, radiaciones y oligohidramnios. Objetivo: Presentar el caso de una recién nacida con este síndrome. Caso clínico: Recién nacida de 41 semanas de gestación con nariz pequeña, labio superior delgado, micrognatia, filtrum largo, implantación baja de orejas, epicanto, cadera displásica con flexión y aducción de miembro inferior derecho y acortamiento del mismo a expensas del muslo. En la imagen radiográfica se encontró hipoplasia de fémur derecho con techo acetabular ipsilateral displásico. Se realizó una evaluación completa por distintos especialistas que descartaron otras malformaciones asociadas. Se programó el alargamiento quirúrgico de miembros inferiores a la edad de 5 meses con la finalidad de que deambule con sus propios pies; paralelamente se inició apoyo con kinesiterapia. Conclusiones: El síndrome de hipoplasia femoral y facies inusual es un padecimiento poco frecuente, que implica la participación de un equipo médico multidisciplinario para su manejo.

Introduction: Femoral hypoplasia-unusual facies syndrome is a rare disease with variable expressivity, although cases have been reported with an autosomal dominant pattern. It particularly affects the structures of the face associated with hypoplasia of the femur. Its aetiology is relatively unknown. However, this syndrome has been associated with maternal diabetes, drug exposure, viral infections, radiation, and oligohydramnios. Objective: The case of a newborn with this syndrome is presented. Clinical case: Newborn of 41 weeks gestation with small nose, thin upper lip, micrognathia, long philtrum, low set ears, epicanthal folds, dysplastic hips showing flexion, and adduction of the right leg, and shortening at the expense of the thigh. X-ray images revealed femoral hypoplasia and dysplastic acetabular roof. Different physicians from other specialties who excluded other associated malformations performed a complete evaluation. Surgical bone lengthening of lower limb is scheduled at 5 months of age, with the purpose that she walks with her own feet; at the same time she began management with kinesiotherapy. Conclusions: Femoral hypoplasia-unusual facies syndrome is a rare condition. A multidisciplinary health care team must treat individuals with femoral hypoplasia-unusual facies syndrome.

Cardiopatias congênitas e malformações extracardíacas / Congenital heart defects and extracardiac malformations / Cardiopatías congénitas y malformaciones extracardiacas

OBJETIVO: Revisar a associação entre cardiopatias congênitas e malformações extracardíacas. FONTES DE DADOS: A pesquisa incluiu artigos científicos presentes nos portais Medline, Lilacs e SciELO, utilizando-se os descritores "congenital heart disease", "congenital heart defects", "congenital cardiac malformations", "extracardiac defects" e "extracardiac malformations". Foram incluídos os artigos de séries de casos que exploravam especificamente a associação entre cardiopatias congênitas e malformações extracardíacas. SÍNTESE DOS DADOS: A cardiopatia congênita é responsável por cerca de 40% dos defeitos congênitos, sendo uma das malformações mais frequentes e a de maior morbimortalidade. Malformações extracardíacas são observadas em 7 a 50% dos pacientes com cardiopatia congênita, trazendo um risco ainda maior de comorbidade e mortalidade e tornando a cirurgia cardíaca mais arriscada. Diferentes estudos têm tentado avaliar a presença de anormalidades extracardíacas em pacientes portadores de cardiopatia congênita. Dentre as alterações descritas, destacam-se aquelas do trato urinário. Contudo, não houve um estudo que tenha avaliado do mesmo modo todos os pacientes. CONCLUSÕES: Anormalidades extracardíacas são frequentes em pacientes com cardiopatia congênita, sendo que os portadores de tais alterações podem apresentar um risco maior de morbimortalidade. Consequentemente, alguns autores vêm discutindo a importância e o custo-benefício da triagem destas crianças à procura de outras malformações por meio de exames complementares.

OBJECTIVE: To review the association between congenital heart defects and extracardiac malformations. DATA SOURCES: Scientific articles were searched in the Medline, Lilacs, and SciELO databases, using the descriptors "congenital heart disease," "congenital heart defects," "congenital cardiac malformations," "extracardiac defects," and "extracardiac malformations." All case series that specifically explored the association between congenital heart defects and extracardiac malformations were included. DATA SYNTHESIS: Congenital heart diseases are responsible for about 40% of birth defects, being one of the most common and severe malformations. Extracardiac malformations are observed in 7 to 50% of the patients with congenital heart disease, bringing a greater risk of comorbidity and mortality and increasing the risks related to heart surgery. Different studies have attempted to assess the presence of extracardiac abnormalities in patients with congenital heart disease. Among the changes described, those of the urinary tract are more often reported. However, no study has evaluated all patients in the same way. CONCLUSIONS: Extracardiac abnormalities are frequent among patients with congenital heart disease, and patients with these alterations may present an increased risk of morbimortality. Therefore, some authors have been discussing the importance and cost-effectiveness of screening these children for other malformations by complementary exams.

OBJETIVO: Revisar la asociación entre cardiopatías congénitas y malformaciones extracardiacas. FUENTES DE DATOS: Se investigaron artículos científicos presentes en los portales Medline, Lilacs y SciELO, utilizándose los descriptores «congenital heart disease¼, «congenital heart defects¼, «congenital cardiac malformations¼, «extracardiac defects¼ y «extracardiac malformations¼. Se incluyeron todos los artículos de casos que exploraban específicamente la asociación entre cardiopatías congénitas y malformaciones extracardiacas. SÍNTESIS DE LOS DATOS: La cardiopatía congénita es responsable por un 40% de los defectos congénitos, siendo una de las malformaciones más frecuentes y la de mayor morbimortalidad. Malformaciones extracardiacas se observan en 7 a 50% de los pacientes con cardiopatía congénita, trayendo un riesgo todavía más grande de comorbilidad y mortalidad y haciendo la cirugía cardíaca más arriesgada. Distintos estudios vienen intentando evaluar la presencia de anormalidades extracardiacas en pacientes portadores de cardiopatía congénita. Entre las alteraciones descriptas, se destacan aquellas del sistema urinario. Sin embargo, no hubo estudio que haya evaluado del mismo modo a todos los pacientes. CONCLUSIONES: Anormalidades extracardiacas son frecuentes en pacientes con cardiopatía congénita, siendo que los portadores de estas alteraciones pueden presentar un riesgo mayor de morbimortalidad. Por consiguiente, algunos autores vienen discutiendo la importancia y el costo-beneficio de la selección de estos niños en búsqueda de otras malformaciones por medio de exámenes complementares.

Multicystic dysplastic kidney - A need for conservative and long term approach.

Objective. We retrospectively studied our cases of Multicystic Dysplastic Kidney (MCDK). The review was aimed at identifying the pattern of the disease in Indian Scenario and the required management thereof. Methods. We studied the clinical, radiological and nuclear scan findings of 22 patients with unilateral MCDK. They were diagnosed and/or treated in our unit from 1999 to 2007. The diagnosis was achieved by Ultrasound and further confirmed by DMSA scans. Other ancillary investigations like Micturating cystourethrogram were done if indicated. These patients were followed and followup investigations consisted of renal ultrasound, blood pressure measurement, and urinalysis and blood biochemistry. Results. A total of 22 patients (18 boys and 4 girls) with unilateral MCDK were investigated and followed for a mean period of 41 months. MCDK was detected on antenatal ultrasound only in 12(55%) and postnatally in 10(45%) babies. Mean age for postnatal diagnosis was 20 months. Follow up ultrasound revealed complete involution of MCDK in 3 patients and partial regression in 11 patients. The size of dysplastic kidney was unchanged in 4 patients and a further 4 patients underwent nephrectomy. Indications of nephrectomy were parental anxiety in 2, hypertension in 1 and palpable mass in 1. Conclusion. Large proportion (45%) of patients in presented series are diagnosed post natally contrary to western world where more than 80% are diagnosed antenatally. Uncomplicated isolated MCDK carry good prognosis with nephrectomy required in only a few patients. Association with other urological anomalies in ipsilateral/contralateral genitourinary tract is important to identify as they have worse outcome in terms of ultimate renal function. All patients with simple/complex unilateral MCDK should be advised long term follow up for the possible development of hypertension and/or hyper infiltration injury.

Síndrome de regresión caudal: caso clínico extremo y revisión de la literatura / Caudal regression syndrome: a severe case report and review of literature

Caudal regression syndrome (SRC) is a disruption of development of distal spinal segments, which affects in most cases, the development of lumbar vertebrae and sacrum. The exact etiology is still unknown; however, it has been related to pre and maternal diabetes, genetics factors and diminished vascular supply. At this time, we present an extreme case of SRC; 4 months old boy, his mother is diabetic, poorly controled, who presents SRC with spinal cord to T2.

El síndrome de regresión caudal (SRC), es una alteración del desarrollo de los segmentos espinales distales, que afecta en la mayoría de los casos el desarrollo del sacro y vértebras lumbares. La etiología exacta aun no esta precisada, sin embargo, se ha relacionado con la diabetes previa y gestacional, factores genéticos y la hipoperfusión vascular. En esta ocasión, se presenta el caso de regresión caudal extrema de un paciente masculino, de 4 meses de edad a la fecha, hijo de madre diabética, mal controlada en embarazo, que presenta SRC con presencia de médula espinal hasta T2.

Gastrosquisis asociada a múltiples malformaciones intestinales congénitas / Multiple intestinal congenital malformations associated to gastroschisis. A case report

Introducción. La asociación de gastrosquisis y múltiples atresias de intestino, suboclusión duodenal por bandas de Ladd y malrotación intestinal es un evento extraordinariamente raro y de consecuencias casi siempre fatales. Caso clínico. Se reporta el caso de una recién nacida con gastrosquisis, 7 atresias intestinales localizadas en yeyuno-íleon, suboclusión duodenal extrínseca por bandas de Ladd y malrotación intestinal. En una primera intervención quirúrgica se efectuó enterolisis duodenal, duodenoplastia simple, yeyunostomía a nivel del primer segmento de atresia, introducción de asas intestinales y cierre de pared en 2 planos. En una segunda intervención quirúrgicas, 17 días después, se efectuó: desprendimiento de yeyunostomía, 5 anastomosis T-T en un plano, gastrostomía tipo Stamm, dejando una sonda en estómago para drenaje y otra sonda de silastic en yeyuno para alimentación. Se implementaron medidas generales de apoyo, ventilación asistida, alimentación parenteral periférica y dieta elemental, seguida de una fórmula con hidrolizado de proteínas, triglicéridos de cadena media y enriquecido con hierro. La ablactación se inició a los 5 meses de edad en forma progresiva y actualmente a los 5 años 10 meses de edad, tiene una dieta y un tránsito intestinal normales, así como un desarrollo pondestatural y psicomotriz de acuerdo a su edad cronológica. Conclusiones. En la revisión de la literatura no se encontró un caso similar, considerándose éste el primer reporte de sobrevida mayor de 1 año. Por lo tanto el manejo instituido en esta paciente pudiera ser sugerido como el adecuado en casos de esta compleja patología
