Achados audiológicos na síndrome de Rubinstein-Taybi: revisão sistemática / Audiological findings in Rubinstein-Taybi syndrome: literature review

Objetivo: Verificar os achados audiológicos em sujeitos portadores da Síndrome de Rubinstein-Taybi (SRT) através de uma busca sistemática na literatura. Métodos: Foram utilizados os descritores "Rubinstein Taybi Syndrome" AND "Hearing" nas principais bases de dados. O levantamento limitou-se a publicações realizadas até junho de 2020, sem limitação de idioma. Foram incluídos todos os estudos que envolvessem avaliações auditivas realizadas em sujeitos portadores da SRT. Foram excluídos da análise, estudos que envolvessem população não portadora de SRT, cartas ao editor e estudos nos quais não foram encontrados os artigos originais. Resultados: A pesquisa resultou na seleção de cinco artigos que evidenciaram que não há uma padronização nos testes audiológicos devido à heterogeneidade das características encontradas na SRT. A perda auditiva do tipo condutiva foi amplamente relatada, porém não foi possível verificar se há um perfil audiológico nesta população. Conclusão: Verificou-se que poucos estudos avaliaram a audição dos portadores de SRT. Além disso, foi possível observar que ainda não são padronizados os testes audiológicos. Recomenda-se que sejam realizados mais estudos com amostras maiores a fim de conhecer quais são as alterações audiológicas mais comuns de modo que se indique precocemente a intervenção terapêutica mais adequada.

New progress in diagnosis and treatment of Rubinstein-Taybi syndrome / 中华实用儿科临床杂志

Rubinstein-Taybi syndrome (RSTS) is a rare congenital neurodevelopmental retardation disease involving multiple organ and system abnormalities.The main manifestations include broad thumbs and big toes, specific facial characteristics, developmental and mental retardation.In addition, it is also manifested as ocular abnormalities, hearing loss, repeated respiratory infection and dyspnea, gastrointestinal disorders, urogenital system disorders and severe constipation.It can be classified into 2 types: RSTS1 (OMIM#180849) caused by the CREBBP gene mutation and RSTS2 (OMIM#613684) caused by the EP300 gene mutation, and most of them are found in the de novo truncated variation.Up to now, a clear diagnosis criterion for RSTS is lacked, which is mainly based on the comprehensive analysis of clinical and genetic results.The main treatment of RSTS is symptomatic and individualized treatment, while early intervention is helpful to improve the prognosis and the quality of life.This study aims to introduce the disease comprehensively, thus enhancing the recognition in RSTS.

Multiple pilomatricomas in twins with Rubinstein-Taybi syndrome

Abstract Pilomatricomas are benign tumors originating from the capillary matrix, which may present as solitary lesions or, less commonly, multiple. Myotonic dystrophy and familial adenomatous polyposis are the most frequently associated disorders with multiple pilomatricomas. There are few reports relating these tumors to other genetic syndromes. Rubinstein-Taybi syndrome is a rare autosomal dominant disorder characterized by intellectual disability and typical dysmorphic characteristics. There are five case reports relating to multiple pilomatricoma to Rubinstein-Taybi syndrome, an association that needs to be clarified. For this reason, we report the first case of multiple pilomatricoma in monozygotic twins with typical Rubinstein-Taybi syndrome.

A Case of Respiratory Arrest after Tonsillectomy and Adenoidectomy Surgery in a Patient with Rubinstein-Taybi Syndrome / 대한이비인후과학회지

Rubinstein-Taybi syndrome (RTS) is a rare autosomal dominant disorder characterized by mental and growth retardation, craniofacial, vertebral, ocular and cardiac anomalies, gastro-esophageal reflux, and difficult airway management. Patients with this syndrome can also experience upper airway obstruction during sleep, which is caused by hypotonia and the abnormal anatomy of the oropharynx and airways, and become susceptible to obstructive sleep apnea. In our case, respiratory arrest developed in an RTS patient who had undergone Tonsillectomy and Adenoidectomy (T&A) surgery. It is the first report of respiratory arrest after T&A surgery in a young child with RTS.

Multiple supernumerary teeth in a child with Rubinstein-Taybi syndrome: a rare feature

Rubinstein-Taybi syndrome is a multiple anomalies congenital disorder characterised by broad thumb and halluces, facial dysmorphism with mental and growth retardation. Oral features include small mouth, retro and micronagthic jaws, highly arched and narrow palate. Dental anomalies such as teeth with talon cusps and screwdriver shaped permanent incisors together with crowded teeth are common features in these patients. Although hyperdontia is said to be one of the features of this condition, nevertheless, presence of multiple supernumerary teeth has never been documented. This report highlighted a case of an eleven-year-old boy with Rubinstein-Taybi syndrome referred for unerupted permanent incisors who exhibited multiple supernumerary teeth radiographically.

Tratamiento percutáneo de cardiopatías congénitas en el síndrome de Rubinstein-Taybi / Percutaneous Treatment of Congenital Heart Defects in the Rubinstein-Taybi Syndrome

El síndrome de Rubinstein-Taybi es producido por una anomalía genética y se caracteriza por una facies típica, anomalías de manos y pies, microcefalia y retraso mental. Alrededor del 30% de los individuos afectados tienen defectos cardíacos congénitos asociados. En esta presentación se describen los casos de dos pacientes con diagnóstico de síndrome de Rubinstein-Taybi asociado con alteraciones cardíacas congénitas. Uno de ellos, de 25 años, presentaba coartación de la aorta nativa, localizada en la región yuxtaductal, y el otro, de 11 meses de edad, mostraba un conducto arterioso permeable de tamaño grande. Ambos pacientes recibieron tratamiento intervencionista percutáneo exitoso, con evolución alejada satisfactoria.

The Rubinstein-Taybi syndrome is a genetic disorder charac-terized by distinctive facial features, anomalies in hands and feet, microcephaly and mental disability. Approximately 30% of subjects affected with this syndrome have associated congenital cardiac defects. This presentation describes two cases of Rubistein-Taybi syndrome with congenital cardiac disorder: a 25-year old patient with native juxtaductal coarctation of the aorta and an 11-month old infant, with large patent ductus arteriosus. Both patients underwent successful percutaneous intervention, with satisfactory long-term outcome.

Pulmonary hypertension due to obstructive sleep apnea in a child with Rubinstein-Taybi syndrome / 소아과

Rubinstein-Taybi syndrome (RTS) is characterized by peculiar facies, mental retardation, broad thumbs, and great toes. Approximately one-third of the affected individuals have a variety of congenital heart diseases. They can also have upper airway obstruction during sleep, due to hypotonia and the anatomy of the oropharynx and airway, which make these patients susceptible to obstructive sleep apnea (OSA). In our case, pulmonary hypertension was caused, successively, by congenital heart defects (a large patent ductus arteriosus and arch hypoplasia) and obstructive sleep apnea during early infancy. The congenital heart defects were surgically corrected, but persistent pulmonary hypertension was identified 2 months after the operation. This pulmonary hypertension was due to OSA, and it was relieved by nasal continuous positive airway pressure. This case is the first report of pulmonary hypertension from OSA in a young infant with RTS.

A Case of Rubinstein-Taybi Syndrome with Optic Disc Coloboma and Chorioretinal Coloboma

PURPOSE: The authors report a case of Rubinstein-Taybi syndrome with optic disc coloboma and chorioretinal coloboma. CASE SUMMARY: A 17-month-old female infant was brought to our clinic presenting exodeviation in the right eye. On cycloplegic refraction, her refractive power was -5.50 D sph -2.50 D cyl axis 180degrees in the right eye and +0.50 D sph in the left eye. On ophthalmologic examination, exotropia of 60 prism diopters with no limitation of ocular movement was observed. Fundus examination showed optic disc coloboma and chorioretinal coloboma in the right eye. The patient's physical characteristics were downward slanted palpebral fissures, long eyelashes, low set ears, and the thumb and the big toe were disproportionately broad. The patient also demonstrated delayed gait abilities. The clinical diagnosis of Rubinstein-Taybi syndrome was given. CONCLUSIONS: The authors report a child with Rubinstein-Taybi syndrome with optic disc coloboma and chorioretinal coloboma, the first to be reported in Korea.

Evaluation of the immune humoral response of Brazilian patients with Rubinstein-Taybi syndrome

Rubinstein-Taybi syndrome (RTS) is a rare developmental disorder characterized by craniofacial dysmorphisms, broad thumbs and toes, mental and growth deficiency, and recurrent respiratory infections. RTS has been associated with CREBBP gene mutations, but EP300 gene mutations have recently been reported in 6 individuals. In the present study, the humoral immune response in 16 RTS patients with recurrent respiratory infections of possible bacterial etiology was evaluated. No significant differences between patients and 16 healthy controls were detected to explain the high susceptibility to respiratory infections: normal or elevated serum immunoglobulin levels, normal salivary IgA levels, and a good antibody response to both polysaccharide and protein antigens were observed. However, most patients presented high serum IgM levels, a high number of total B cell and B subsets, and also high percentiles of apoptosis, suggesting that they could present B dysregulation. The CREBBP/p300 family gene is extremely important for B-cell regulation, and RTS may represent an interesting human model for studying the molecular mechanisms involved in B-cell development.

A case of Rubinstein-Taybi Syndrome with a CREBbinding protein gene mutation / 소아과

Rubinstein-Taybi syndrome (RTS) is a congenital disorder characterized by typical facial features, broad thumbs and toes, with mental retardation. Additionally, tumors, keloids and various congenital anomalies including congenital heart defects have been reported in RTS patients. In about 50% of the patients, mutations in the CREB binding protein (CREBBP) have been found, which are understood to be associated with cell growth and proliferation. Here, we describe a typical RTS patient with Arnold-Chiari malformation. A mutation in the CREBBP gene, c.4944_4945insC, was identified by mutational analysis.
