A Clinical Study Of 31 Individuals With Midline Facial Defects With Hypertelorism And A Guideline For Follow-up.

In order to contribute to clinical delineation of midline facial defects with hypertelorism (MFDH) and to etiologic diagnosis of the isolated form, 31 patients with MFDH unaffected by known syndromic associations were evaluated. Group A included patients personally examined by the authors, while Group B included those previously evaluated by other geneticists. Among the 14 patients from Group A, there were 7 with distinct pictures of multiple congenital anomalies. In Group B, 5 of the 17 patients also exhibited a distinct pattern of defects. Among isolated MFDH, there was association with anomalies of the skull and facial bones (13/14), otorhinologic (11/16), central nervous system (9/16), and ocular (6/7), and audiologic (3/16); 1/3 of the cases had a relevant gestational intercurrences. Isolated FNM may have involvement of environmental components in some cases; the possibility of a syndromic picture should be extensive investigated. Follow-up of such patients must include the examinations herein performed.65396-40

Craniofacial anomalies: description and evaluation of treatment under the Brazilian Unified Health System

The first initiative for treating craniofacial anomalies under the Brazilian Unified Health System was in 1993. An important step was the creation of the Reference Network for Craniofacial Treatment. There are now 29 services listed in this Network. The current study aimed to describe and assess the general characteristics of healthcare in this Network. Data were colleted by a questionnaire, sent to the centers. Response rate was 86.2%. The results showed an increase in services in Southeast Brazil, in universities, and in relation to cleft lip and palate; public financing was prevalent; team composition was largely in accordance with North American standards; routine care occurred in 90%; and 70% used clinical protocols. The Network's name does not appear to entirely reflect its scope. The results show the need to review the Network's definition, aims, and achievements and the standards for inclusion of craniofacial centers.A primeira iniciativa para incluir a atenção às anomalias craniofaciais no SUS ocorreu em 1993. Um importante avanço foi a criação da Rede de Referência no Tratamento de Deformidades Craniofaciais (RRTDCF), atualmente com 29 centros credenciados. Os objetivos deste estudo foram descrever e avaliar as características gerais da atenção às anomalias craniofaciais nos centros que integram a referida rede. Foi utilizado questionário semi-estruturado, remetido por correio. Obteve-se 86,2% de respostas. Os resultados demonstram agregação de centros no Sudeste, em universidades e na área de fissuras labiopalatais; financiamento predominantemente público; equipes constituídas principalmente de acordo com parâmetros norte-americanos; atendimento de rotina em cerca de 90% e utilização de protocolos em cerca de 70% dos centros. A denominação da RRTDCF não parece corresponder à sua abrangência. Os achados sugerem necessidade de revisão da definição, objetivos e abrangência da RRTDCF e dos critérios de credenciamento de centros.91392

Developmental aspects of oral language in craniosynostosis

BACKGROUND: aspects of language development in craniosynostosis. Craniosynostosis (premature fusion of the cranial sutures) has an incidence of 0.4 to 1/1.000 newborns. Etiology for this congenital anomaly includes environmental and genetic factors. Regarding the form of presentation, it can occur in its isolated form or associated to other congenital anomalies. For this last group, acrocephalosyndactilies are observed. These are genetically determined conditions which present phenotypic similarity, including the following syndromes: Saethre-Chotzen, Apert, Crouzon e Pfeiffer. As all of these conditions affect the craniofacial development, it is possible to find anatomic and functional interferences which determine language delays and/or deficits. AIM: to revise the literature concerning aspects related to normal verbal language development and to describe the main characteristics associated to this condition in children who present Apert, Crouzon, Pfeiffer and Saethre-Chotzen syndromes. A systematic review on syndromic craniosynostosis and oral language was performed, consulting Medline, Lilacs and other important references on this theme. CONCLUSION: several manifestations related to hearing and language have been detected in individuals with syndromic craniosynostosis. The most important are alterations in the sound conduction system, leading to hearing losses, and consequently interfering in language acquisition and development. For this reason, speech-language diagnosis and early intervention are recommended in order to eliminate or minimize damages in language acquisition and development.TEMA: aspectos sobre o desenvolvimento de linguagem oral em craniossinostoses sindrômicas. As craniossinostoses (fusão precoce das suturas cranianas) apresentam incidência em torno de 0,4 a 1/1.000 nativivos. Estas podem ocorrer devido a fatores ambientais ou genéticos. Com relação à forma de apresentação, estas podem ocorrer de maneira isolada ou associada a outros defeitos congênitos. Neste último grupo, destacam-se as acrocefalossindactilias, condições geneticamente determinadas, que apresentam similaridade fenotípica, sendo estas as síndromes de Saethre-Chotzen, Apert, Crouzon e Pfeiffer. Diante destas condições complexas que envolvem o arcabouço craniofacial, é possível encontrar interferências anatômicas e funcionais que determinem atrasos e/ou desvios de linguagem. OBJETIVO: revisar a literatura acerca dos aspectos fonoaudiológicos relacionados ao desenvolvimento normal da linguagem oral e descrever as principais características associadas a ela apresentadas por crianças com síndromes de Apert, Crouzon, Pfeiffer e Saethre-Chotzen. Foi realizada revisão sistemática de estudos sobre as craniossinostoses sindrômicas e dados referentes a linguagem oral nestes casos. Para isso, utilizou-se pesquisa na base de dados Medline e Lilacs, assim como outras publicações importantes para a conclusão do artigo. CONCLUSÃO: diversas manifestações relacionadas à audição e linguagem podem estar presentes em craniossinostoses sindrômicas. Destacam-se as alterações do sistema de condução do som, levando à perda auditiva, o que conseqüentemente prejudica a aquisição e desenvolvimento pleno da linguagem. Deste modo, recomenda-se o diagnóstico e tratamento fonoaudiológico adequados e precoces, eliminando ou minimizando os prejuízos para a aquisição e desenvolvimento da linguagem oral.21322

Angular Analysis Of Corpus Callosum In 18 Patients With Frontonasal Dysplasia.

Considering the rarity of the frontonasal dysplasia (FD) and the few reports about it in a large casuistry using magnetic resonance image (MRI), we describe the results of the angular analysis of the corpus callosum of 18 individuals with FD (7 male, 11 female), using an easily-reproductive method. Group I had 12 individuals with isolated form and Group II had 6 individuals with FD syndromic with unknown etiology. The results are presented in set. Comparing with the control group, patients with FD presented alpha angle increase and beta and gamma angles reduction (p<0.05). Alpha and gamma angles express the relationship between the anterior portion of corpus callosum and the floor of 4th ventricle. Considering the embryonary development, these findings would occur secondarily to failure during the development of nasal capsula. Thus, angular anomaly in corpus callosum would be a usual finding, and not fortuitous in patients with FD.62195-

O Grupo I foi formado por 12 indivíduos com DF isolada e o Grupo II, por 6 portadores de DF sindrômica de etiologia desconhecida. Não houve diferença entre os grupos, e os dados são apresentados em conjunto. Comparando com o grupo controle, houve aumento significativo do ângulo alfa e redução dos ângulos beta e gama (p<0,05) Os ângulos alfa e gama expressam a relação entre a porção anterior do corpo caloso e do piso do 4º ventrículo. Esses achados radiológicos poderiam ocorrer secundariamente à falência do desenvolvimento da cápsula nasal. Assim, as anomalias angulares no corpo caloso poderiam ser um achado usual, e não fortuito, na DF.19519

Cranial nerve cavernous malformations causing trigeminal neuralgia and chiasmal apoplexy: report of 2 cases and review of literature

Objective: To verify whether fluorescence in situ hybridization (FISH) of cells from the buccal epithelium could be employed to detect cryptomosaicism with a 45,X lineage in 46,XY patients. Subjects and methods: Samples of nineteen 46,XY healthy young men and five patients with disorders of sex development (DSD), four 45,X/46,XY and one 46,XY were used. FISH analysis with X and Y specific probes on interphase nuclei from blood lymphocytes and buccal epithelium were analyzed to investigate the proportion of nuclei containing only the signal of the X chromosome. Results: The frequency of nuclei containing only the X signal in the two tissues of healthy men did not differ (p = 0.69). In all patients with DSD this frequency was significantly higher, and there was no difference between the two tissues (p = 0.38), either. Conclusions: Investigation of mosaicism with a 45,X cell line in patients with 46,XY DSD or sterility can be done by FISH directly using cells from the buccal epithelium.Objetivo: Verificar se a hibridização in situ por fluorescência (FISH) em células de mucosa oral poderia ser empregada para detectar criptomosaicismo com linhagem 45,X em pacientes 46,XY. Sujeitos e métodos: Amostra de 19 jovens saudáveis 46,XY e cinco pacientes com distúrbios da diferenciação do sexo (DDS), quatro 45,X/46,XY e um 46,XY. FISH com sondas específicas para X e Y em núcleos interfásicos de linfócitos e mucosa oral para investigar a proporção de núcleos contendo apenas o sinal do cromossomo X. Resultados: A frequência de núcleos contendo apenas o sinal do X nos dois tecidos dos homens saudáveis não diferiu (p = 0,69). Em todos os pacientes com DDS essa frequência foi significativamente maior, e também não houve diferença entre os dois tecidos (p = 0,38). Conclusões: A investigação de mosaicismo com linhagem 45,X em pacientes com DDS 46,XY ou esterilidade pode ser feita por FISH diretamente em células de mucosa oral

Experiência de profissionais de saúde da família com pessoas com fendas orofaciais no Brasil

INTRODUCTION: Orofacial clefts are among the most prevalent birth defects worldwide. Specialized treatment and surveillance of basic health needs are critical. Few studies have investigated primary care practitioners' experience in caring for individuals with clefts. OBJECTIVE: It was to describe experience and current interest of family care practitioners on the management of individuals with clefts. METHODS: Observational cohort of 104 practitioners from Maceió (AL) e Campinas (SP). Demographic, academic and professional characteristics, didactic experience and desire in continuing education on clefts were assessed using a questionnaire RESULTS:Seventy-four practitioners were located in Maceió and 30 in Campinas. Female gender and low academic qualification were predominant. Physicians and nurses prevailed over dentists, 78 (75%) participants had clinical experience with clefts. Use of protocols was mentioned by 3/104 (2.9%), provision of information on clefts by 58/104 (56%) and referrals to the Brazilian Reference Network by 7/104 (6.7%). Almost 50% reported didactic experience and 94%, desire on continuing education in this field CONCLUSION: Results corroborate the literature and reinforce the need of improving family care practitioners' skills to manage individuals with clefts. Education and strengthen ties between primary level of the health system and specialized teams must be focused. Some strategies are presented in this regard.INTRODUÇÃO: As fendas orofaciais estão entre os mais prevalentes defeitos congênitos em todo o mundo.

Antropometria e composição de massa corporal sugerem achado intrínseco da síndrome de Williams-Beuren

OBJECTIVE:Although considered a well-known condition, there is only one study describing the body composition among individuals with Williams-Beuren syndrome. The aim was to characterize the nutritional status in Brazilian individuals with this condition. METHODS: Cross-sectional study was designed to evaluate clinical and nutritional data of 17 Brazilian patients. Z-scores for height, weight, body mass index, triceps and subscapular skinfold thickness, arm circumference, arm muscle area, arm fat area were calculated. Wilcoxon's test was used to investigate differences between the z-scores of the anthropometrical measures and zero. RESULTS: Four children were considered stunted and two severely malnourished. The z-score mean value for height was -1.14 ± 1.00 (p-value = 0.004), for weight, -0.67 ± 1.19 (p-value = 0.0443), for arm circumference, -0.94 ± 1.14 (p-value = 0.0222), for triceps skinfold thickness, -0.59 ± 0.63 (p-value = 0.0042) and for arm fat area -0.67 ± 0.67 (p-value = 0.0061). CONCLUSION: Short stature seen in this series confirms a previous study describing this feature in a German population, which would suggest it as an intrinsic feature in Williams-Beuren syndrome. In addition, skinfold thickness measures have not been previously performed in this syndrome and detected abnormalities in fat stores in this sample. Considering this method a fast and low-cost way to evaluate body composition, similar studies could be performed in other populations in order to better characterize this issue. Morbidity related with this genetics condition and information for clinical investigation and clinical follow-up are also discussed.OBJETIVO: Embora a síndrome de Williams-Beuren seja bem conhecida, há apenas um estudo descrevendo a composição corporal nesses pacientes. O objetivo foi caracterizar o estado nutricional de brasileiros com síndrome de Williams. MÉTODOS: Utilizou-se um estudo transversal com a avaliação de dados clínicos e nutricionais de 17 pacientes. Foram calculados os escores-z do peso, estatura, índice de massa corpórea, dobras cutâneas, circunferência do braço e áreas muscular e adiposa do braço. Para verificar diferenças, foi utilizado o teste de Wilcoxon, sendo considerado significativo p < 0,05. RESULTADOS: Os valores médios dos escores-z foram: -1,14 ± 1,00 (p = 0,004) para estatura, -0,67 ± 1,19 (p = 0,0443) para peso, -0,94 ± 1,14 (p = 0,0222) para a circunferência do braço, -0,59 ± 0,63 (p = 0,0042) para dobra cutânea do tríceps e -0,67 ± 0,67 (p = 0,0061) para a área gordurosa do braço. Foi observada desnutrição pregressa em quatro pacientes e crônica, em dois. CONCLUSÃO: A baixa estatura, semelhante à descrita na população alemã, parece ser intrínseca à síndrome. Esse foi o primeiro estudo que avaliou a composição corporal, utilizando as dobras cutâneas, e detectou anormalidades nas reservas de gordura. O método aqui utilizado é simples, rápido e de baixo custo, facilitando estudos similares em outras populações. Isso poderia melhor caracterizar esses aspectos na síndrome de Williams. Morbidade relacionada a essa doença e informações para investigação e seguimento clinico são discutidas.68168
