Alcohol consumption during pregnancy by women from southern Brazil: a cross-sectional study.

BACKGROUND: Some maternal characteristics are related to alcohol intake during pregnancy, which irreversibly compromises the maternal-fetal binomial integrity. OBJECTIVES: To identify the frequency, impact, and factors associated with alcohol consumption during pregnancy. DESIGN AND SETTING: A cross-sectional study was performed at the Hospital Materno Infantil Presidente Vargas (HMIPV) in Porto Alegre/RS between March and December 2016. METHODS: A structured questionnaire was administered along with a medical records review. They refer to the maternal sociodemographic and gestational status, alcohol consumption patterns, and characteristics of the fetus/newborn. In the statistical analysis, P values < 0.05 were considered significant. RESULTS: The frequency of alcohol intake was 37.3%; this was characterized by the consumption of fermented beverages (89.3%), especially during the first trimester (79.6%). Risky consumption (high and/or early) occurred for 30.2% of participants. Risk factors associated with maternal alcohol consumption during pregnancy were tobacco use (P < 0.001) and abortion attempt (P = 0.023). Living with a partner (P = 0.002) and planning pregnancy (P = 0.009) were protective factors. Risky consumption was related to all of the aforementioned variables as well as threatened abortion (P = 0.023). CONCLUSIONS: Alcohol intake during pregnancy is common and affects nearly one-third of pregnant women. Knowledge of the population at risk and protective factors is essential for the development of campaigns that seek to reduce consumption and, therefore, its consequences for the mother and fetus.

Patients' prognosis with congenital heart disease followed by ten years: survival and associated factors / Prognóstico de pacientes com cardiopatia congênita seguidos por dez anos: sobrevida e fatores associados

ABSTRACT Objective: To evaluate the prognosis and influence of associated factors in patients with congenital heart disease admitted for the first time to the Intensive Care Unit of the Hospital da Criança Santo Antônio/Irmandade da Santa Casa de Misericórdia de Porto Alegre, especially those factors associated with death. Methods: Patients were prospectively and consecutively allocated over a period of one year (August 2005 to July 2006). Now, 15 years after the initial selection, we collected data from these patients in the database of the Cytogenetics Laboratory of the Universidade Federal de Ciências da Saúde de Porto Alegre and in the medical records of the hospital. Results: Of the 96 patients, 11 died and 85 were alive until 20 years old. Four patients died in the Intensive Care Unit. The survival probability up to 365 days of life was 95.8%. The survival assessment identified that the deaths occurred mainly before the patients completed one thousand days of life. We found that complex heart disease was independently associated with an odds ratio of 5.19 (95% confidence interval — CI:1.09-24.71; p=0.038) for death. Conclusions: Knowledge about the factors that interfere with the prognosis can be crucial in care practice planning, especially considering that congenital heart disease is an important cause of mortality in the first year of life.

RESUMO Objetivo: Avaliar o prognóstico e a influência de fatores associados em pacientes com cardiopatia congênita internados pela primeira vez na Unidade de Terapia Intensiva do Hospital da Criança Santo Antônio/Irmandade da Santa Casa de Misericórdia de Porto Alegre, principalmente aqueles fatores associados ao óbito. Métodos: Os pacientes foram alocados prospectiva e consecutivamente por um período de um ano (agosto de 2005 a julho de 2006). Agora, 15 anos após a seleção inicial, coletamos dados desses pacientes no banco de dados do Laboratório de Citogenética da Universidade Federal de Ciências da Saúde de Porto Alegre e nos prontuários do hospital. Resultados: Dos 96 pacientes, 11 faleceram e 85 permaneceram vivos até completar 20 anos. Quatro pacientes morreram na Unidade de Terapia Intensiva. A probabilidade de sobrevida até 365 dias de vida foi de 95,8%. A avaliação da sobrevida identificou que os óbitos ocorreram principalmente antes de os pacientes completarem mil dias de vida. Verificamos que a doença cardíaca complexa foi independentemente associada a um odds ratio de 5,19 (intervalo de confiança — IC95% 1,09-24,71; p=0,038) para morte. Conclusões: O conhecimento dos fatores que interferem no prognóstico pode ser fundamental no planejamento da prática assistencial, principalmente considerando-se que as cardiopatias congênitas são importante causa de mortalidade no primeiro ano de vida.

Risk factors and characteristics of the birth of patients with craniofacial microsomia, a case-control study.

BACKGROUND: Craniofacial microsomia (CM) is characterized by changes in the first and second branchial arches. It is a clinical condition whose etiology is still uncertain, but studies have shown that genetic, nutritional, and environmental factors can result in disorders of blastogenesis of the branchial arches. This study evaluates gestational aspects, focusing on possible risk factors associated with CM. METHODS: This is a case-control study conducted with patients monitored at a medical genetics service and compared to a control group of patients without evidence of malformations, born in a mother and child hospital, both located in Porto Alegre, Southern Brazil. Mothers' data were obtained using questionnaires and by reviewing medical records. The sample consisted of 43 patients with CM (cases) and 129 patients without evidence of malformations (controls), paired by sex, totaling three controls for each case. Data analysis was performed using the two-tailed Fisher's exact test, Pearson's chi-square test, and the t-test. RESULTS: We identified several factors associated with the development of CM, including the use of abortion methods by the mothers of these babies (p = .001), maternal diabetes (p = .009), advanced maternal age (p = .035), and a history of vaginal bleeding (p < .001). Furthermore, these patients exhibited a tendency to be born prematurely (p = .027), with low birth weight (p = .007), and lower Apgar scores (p = .003) when compared to healthy infants. Using a multivariate model, the use of abortion methods (p = .003) and vaginal bleeding (p = .032) remained independently associated with craniofacial microsomia. CONCLUSIONS: We have identified several risk factors for the development of CM, including a propensity for premature birth, low birth weight, and respiratory difficulties. Additionally, women of advanced maternal age and/or those who used abortion methods and/or have diabetes have a higher risk of giving birth to a baby with CM. This information can be valuable in clinical practice, especially for the prevention of future cases.

PDGFRA, KIT, and KDR Gene Amplification in Glioblastoma: Heterogeneity and Clinical Significance.

Glioblastoma (GBM) is the most frequent tumor of the central nervous system, and its heterogeneity is a challenge in treatment. This study examined tumoral heterogeneity involving PDGFRA, KIT, and KDR gene amplification (GA) in 4q12 and its association with clinical parameters. Specimens from 22 GBM cases with GA for the 4q12 amplicon detected by FISH were investigated for homogeneous or heterogeneous coamplification patterns, diffuse or focal distribution of cells harboring GA throughout tumor sections, and pattern of clustering of fluorescence signals. Sixteen cases had homogenously amplification for all three genes (45.5%), for PDGFRA and KDR (22.7%), or only for PDGFRA (4.6%); six cases had heterogeneous GA patterns, with subpopulations including GA for all three genes and for two genes - PDGFRA and KDR (13.6%), or GA for all three and for only one gene - PDGFRA (9.1%) or KIT (4.6%). In 6 tumors (27.3%), GA was observed in focal tumor areas, while in the remaining 16 tumors (72.7%) it was diffusely distributed throughout the pathological specimen. Amplification was universally expressed as double minutes and homogenously stained regions. Coamplification of all three genes PDGFRA, KIT, and KDR, age ≥ 60 years, and total tumor resection were statistically associated with poor prognosis. FISH proved effective for detailed interpretation of molecular heterogeneity. The study uncovered an even more diverse range of amplification patterns involving the 4q12 oncogenes in GBM than previously described, thus highlighting a complex tumoral heterogeneity to be considered when devising more effective therapies.

Características clínicas e fonoaudiológicas de neonatos hospitalizados em uma Unidade de Tratamento Intensivo neonatal com suspeita de doença genética / Clinical and speech-language pathology characteristics of neonates hospitalized in a neonatal Intensive Care Unit with suspected genetic disease / Características clínicas y de patología del habla y lenguaje de neonatos hospitalizados en una Unidad de Cuidados Intensivos neonatales con sospecha de enfermedad genética

Introdução: A prematuridade é um fator de risco para o crescimento e o desenvolvimento dos neonatos. Objetivo: Analisar as características clinicas e fonoaudiológicas de neonatos hospitalizados na unidade de tratamento intensivo (UTI) neonatal com suspeita de doença genética. Material e Método:Estudo transversal descritivo, conduzido em um hospital na região sul do Brasil com coleta de dados entre novembro de 2020 e setembro de 2021. Todos os neonatos que se encontravam internados na UTI, atendidos pelo Sistema Único de Saúde e que apresentavam suspeita de etiologias genéticas foram acompanhados pela equipe de Fonoaudiologia. Foram analisados todos os prontuários dos recém-nascidos com suspeita de alteração genética, extraindo-se os dados médicos e fonoaudiológicos. Resultados:A amostra foi constituída por 14 neonatos prematuros com média de idade gestacional de 36 semanas e 5 dias e uma média de tempo de nascimento, no momento da avaliação fonoaudiológica, de 14,6 dias de vida. No que se refere às comorbidades, 71,4% dos recém-nascidos apresentavam alguma malformação, sendo múltiplas na maior parte dos casos (64,29%). Todos os neonatos estavam fazendo uso de via enteral de alimentação durante a avaliação fonoaudiológica. Na avaliação de reflexos orais, observou-se que houve um predomínio de pacientes com reflexo de procura débil, sendo que a maior parte apresentava reflexo de sucção presente. Conclusões: Pode-se afirmar que, neste estudo, a amostra foi composta por pacientes principalmente prematuros que apresentavam malformações múltiplas e que todos faziam uso de via alternativa de alimentação sugerindo, assim, a necessidade de atendimento fonoaudiológico como parte da assistência multidisciplinar desses neonatos.

Introduction: Prematurity is a risk factor for the growth and development of neonates. Objective: To analyze clinical and speech therapy characteristics of neonates hospitalized in the neonatal intensive care unit with suspected genetic disease. Method: Descriptive cross-sectional study conducted in a hospital in southern Brazil with data collection between November 2020 and September 2021. All neonates who were hospitalized in the ICU attended by the public health system and who were suspected of having genetic etiologies were followed up by the Speech-Language Pathology team. All newborn`s medical records with suspected genetic alterations were analyzed and the medical and the speech-language pathology data were analyzed. Results: The sample consisted of 14 premature neonates with a mean gestational age of 36 weeks and 5 days and a mean time of birth, at the time of the speech-language pathology assessment, of 14.6 days of life. Regarding to comorbidities, 71.4% of newborns had some malformation, being multiple in most cases (64.29%). All neonates were using enteral feeding at the time of the speech-language evaluation. At the oral reflexes evaluation it was observed that there was a predominance of patients with a weak rooting reflex and most of them had a present sucking reflex. Conclusions: In this study the sample consisted of mainly premature patients who had multiple malformations and all of them used an alternative feeding route, thus suggesting the demand for speech therapy as part of the multidisciplinary care of these neonates.

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.

Chromosomal abnormalities detected by karyotyping among patients with secondary amenorrhea: a retrospective study

ABSTRACT BACKGROUND: Chromosomal abnormalities (CAs) have been described in patients with secondary amenorrhea (SA). However, studies on this association are scarce. OBJECTIVES: To evaluate the frequency and types of CAs detected by karyotyping in patients with SA. DESIGN AND SETTING: This retrospective study was performed in a reference clinical genetic service in South Brazil. METHODS: Data were obtained from the medical records of patients with SA who were evaluated between 1975 and 2022. Fisher's bicaudate exact test and Student's t-test were used, and P < 0.05 was considered significant. RESULTS: Among 43 patients with SA, 14 (32.6%) had CAs, namely del (Xq) (n = 3), 45,X (n = 2), 46,X,r(X)/45,X (n = 2), 46,XX/45,X (n = 1), 46,X,i(q10)/45,X (n = 1), 47,XXX (n = 1), 46,XX/47,XXX (n = 1), 46,XX/47,XX,+mar (n = 1), 45,XX,trob(13;14)(q10;q10)/46,XXX,trob(13;14)(q10;q10) (n = 1), and 46,XX,t(2;21)(q23;q11.2) (n = 1). Additional findings were observed mostly among patients with CA compared with those without CA (P = 0.0021). No difference in the mean age was observed between the patients with SA with or without CAs (P = 0.268025). CONCLUSIONS: CAs are common among patients with SA, especially those with short stature and additional findings. They are predominantly structural, involve the X chromosome in a mosaic, and are compatible with the Turner syndrome. Patients with SA, even if isolated, may have CAs, particularly del (Xq) and triple X.

Trisomy 21 and Ebstein Anomaly: Diagnosis and Prognosis of a Rare Association.

Trisomy 21 is considered the most common chromosomal aneuploidy, and congenital heart disease (CHD) is highly prevalent and relevant to the morbidity and mortality of these patients. Ebstein anomaly (EA) is a rare CHD characterized by tricuspid valve dysplasia with inferior septal leaflet displacement. Herein, we described a patient with trisomy 21 who presented with EA and discuss the association between the two conditions based on a literature review. We conclude that the concomitant occurrence of both conditions is considered to be rare. These individuals are most frequently diagnosed during birth and childhood, and they usually have a good prognosis, as observed with our patient and is typical for EA patients in general. However, it is important to be aware that electrophysiologic anomalies may also be present.

Clinical and cytogenetic characteristics of patients diagnosed with Turner syndrome in a clinical genetics service: cross-sectional retrospective study

ABSTRACT BACKGROUND: Turner syndrome (TS) is a rare genetic disease. Understanding its clinical findings contributes to better management of clinical conditions. OBJECTIVE: To investigate the clinical and karyotypic characteristics of patients diagnosed with TS at two reference services for clinical genetics in southern Brazil. DESIGN AND SETTING: Retrospective cross-sectional study conducted in two clinical genetics services in Porto Alegre (RS), Brazil. METHODS: The sample consisted of 59 patients with TS diagnosed from 1993 to 2019. A review of their medical records was performed and a standard protocol was filled out. RESULTS: The average age of the patients at diagnosis was 15.9 years, and 40.7% were over 13 years old. The largest proportion of them (42.4%) had been referred from an endocrinology department and their constitution was 45,X (40.7%). The most common clinical findings were short stature (85.7%), hypoplastic/ hyperconvex nails (61.2%), low posterior hairline (52.1%) and cubitus valgus (45.8%). There was no difference regarding the presence of short stature (P = 0.5943), number of dysmorphia (P = 0.143), anatomical regions affected and malformations identified through imaging examinations (P = 1.0000), regarding the presence or absence of 45,X constitution. Only 6% of the patients had used growth hormone and 43%, estrogen. CONCLUSION: We found that, in general, patients with TS were being diagnosed late. This has important implications for their treatment. In addition, only a small proportion of the patients were undergoing further examination or evaluation, which appeared to be leading to underdiagnosis of many abnormalities.

Unusual Characteristics and Variable Expressivity in a Brazilian Family with Cherubism.

Cherubism is a rare genetic condition characterized by a bone nonneoplastic disease. We aimed to report a 6-year-old girl with cherubism presenting similar cases in the maternal family. However, her mother and grandmother seemed to be asymptomatic. The patient had an enlarged and asymmetric jaw with multiple enlarged cervical lymph nodes that increased in size with time. Sanger sequencing revealed a heterozygous mutation in exon 9 of SH3BP2 not only in the patient but also in her mother. Thus, we observed a variable expression and a probably reduced penetrance within the family, as well as unusual characteristics of the patient (in this case, the asymmetrical involvement of the jaw).

Diagnósticos de enfermagem na síndrome de Turner / Nursing diagnoses in Turner syndrome

A síndrome de Turner é uma doença genética rara e possui repercussão importante na assistência em saúde destas pacientes. Apesar da ST não ser incomum, ainda existem lacunas na literatura acerca da assistência de enfermagem. O objetivo do trabalho foi inferir diagnósticos de enfermagem a partir das condições clínicas apresentadas pelas pacientes com síndrome de Turner (ST), conforme a taxonomia II NANDA-I. Trata-se de um estudo transversal e retrospectivo, de abordagem quantitativa. A amostra foi constituída por 59 pacientes com ST, diagnosticadas no período de 1993 a 2019. Os dados foram extraídos dos seus prontuários e submetidos à inferência diagnóstica pautados na taxonomia II NANDA-I. O julgamento clínico ocorreu com as principais dismorfias descritas entre as pacientes. No que tange aos resultados, a constituição cromossômica mais frequente foi a monossomia do cromossomo X (40,7%) e a média de idade do diagnóstico das pacientes foi de 15,9 anos (variou de 1 mês a 34 anos). As principais dismorfias descritas foram: baixa estatura, cúbito valgo, pectus excavatum e palato ogival. Os diagnósticos inferidos para a população estudada foram isolamento social, mobilidade física prejudicada, deglutição prejudicada, baixa autoestima situacional e padrão respiratório ineficaz. Concluiu-se que a proposição de diagnósticos de enfermagem possibilita qualificar a assistência destas pacientes, a partir de evidências no cuidado à pacientes com doenças raras.

Turner's syndrome (TS) is a rare genetic disease and has an important impact on the health care of these patients. Although TS is not uncommon, there are still gaps in the literature about nursing care. The objective of the study was to infer nursing diagnoses from the clinical conditions presented by patients with Turner syndrome, according to NANDA-I taxonomy II. This is a cross-sectional and retrospective study, with a quantitative approach. The sample consisted of 59 patients with TS, diagnosed from 1993 to 2019. The data were extracted from their medical records and submitted to diagnostic inference based on the NANDA-I taxonomy II. The clinical judgment occurred with the main dysmorphias described among the patients. Regarding the results, the most common chromosomal constitution was X chromosome monosomy (40.7%) and the mean age of the patients at diagnosis was 15.9 years (ranged from 1 month to 34 years). The main dysmorphias described were: short stature, ulna valgus, pectus excavatum, and ogival palate. The diagnoses inferred for the studied population were social isolation, impaired physical mobility, impaired swallowing, low situational self-esteem, and ineffective breathing patterns. It was concluded that the proposal of nursing diagnoses makes it possible improve the assistance of these patients, based on evidence in the care of patients with rare diseases.

Candidate genes of oculo-auriculo-vertebral spectrum in 22q region: A systematic review.

Oculo-auriculo-vertebral spectrum (hemifacial microsomia/OAVS, OMIM #164210) is a heterogenous and congenital condition caused by a morphogenesis defect of the first and second pharyngeal arches. Etiology includes unknown genetic, environmental factors and chromosomal alterations, which 22q11.2 region is the most frequently reported. Several candidate genes for OAVS have been proposed; however, none has been confirmed as causative of the phenotype. This review aims to sum up all clinical and molecular findings in 22q region of individuals diagnosed with OAVS and to investigate genes that may be involved in the development of the spectrum. A search was performed in PubMed using all entry terms to OAVS and Chromosome 22q11. After screening, 11 papers were eligible for review. Deletions and duplications in the q11.2 region were the most frequent (18/22) alterations reported and a total of 68 genes were described. Our systematic review reinforces the hypothesis that 22q11 region is a candidate locus for OAVS as well as CLTCL1, GSC2, HIRA, MAPK1, TBX1, and YPEL1 as potential candidates genes for genotype-phenotype correlation. Complementary studies regarding genes interaction involved in the 22q11 region are still necessary in the search for a genotype-phenotype association, since the diagnosis of OAVS is a constant medical challenge.

Visual loss as first clinical manifestation of X-linked adrenoleukodystrophy / Perda visual como primeira manifestação clínica de adrenoleucodistrofia ligada ao X

Abstract X-linked adrenoleukodystrophy (X-ALD) represents a group of diseases characterized by the accumulation of very long chain fattyacids (VLCFAs) in the tissues. Its clinical manifestations are usually manifold. Visual changes may be present, but they often appear later in the disease. We describe here the case of a 9-year-old boy with X-ALD, whose first symptom was visual loss, which began at 8 years of age. His ophthalmologic evaluation revealed no alterations. Shortly thereafter, he suffered a head injury. The magnetic resonance imaging of brain revealed findings that led to the suspicion of X-ALD. The plasma VLCFA dosage confirmed this diagnosis. This report aims toshow that in cases of visual loss with a normal ophthalmic examination, a high index of suspicion should be given for conditions suchas X-ALD, since it affects the cortical routes related to vision. Fundoscopy findings appear late in X-ALD.

Resumo A adrenoleucodistrofia ligada ao X (X-ALD) representa um grupo de doenças caracterizadas pelo acúmulo de ácidos graxos de cadeia muito longa (VLCFAs) nos tecidos. Suas manifestações clínicas costumam ser múltiplas. Alterações visuais podem estar presentes, contudo costumam surgir mais tardiamente na doença. Descrevemos aqui o caso de um menino de 9 anos com X-ALD, cujo primeiro sintoma foi perda visual, iniciada aos 8 anos de idade. A sua avaliação oftalmológica não revelou alterações. Pouco tempo depois, ele sofreu um traumatismo craniano. A imagem de ressonância magnética de encéfalo revelou achados que levaram a suspeita de X-ALD. A dosagem dos VLCFAs no plasma confirmou este diagnóstico. Este relato tem como objetivo mostrar que em casos de perda visual com um exame oftalmológico normal, deve-se ter um alto índice de suspeita para condições como a X-ALD, pois a mesma afeta as vias corticais relacionadas à visão. Nessa doença, os achados da fundoscopia aparecem mais tardiamente.

WAGRO syndrome: a rare genetic condition associated with aniridia and additional ophthalmologic abnormalities / Síndrome WAGRO: uma condição genética rara associada à aniridia e a anormalidades oftalmológicas adicionais

ABSTRACT Aniridia is a congenital eye disorder with a variable degree of hypoplasia or absence of iris tissue. It is caused by loss of function of the PAX6 gene and may be an isolated ocular abnormality or part of a syndrome. WAGRO refers to a rare genetic condition leading to Wilms tumor, aniridia, genitourinary anomalies, mental retardation, and obesity and is caused by a deletion of the short arm of chromosome 11 (11p), where the PAX6 gene is located. Here, we report on an 8-year-old boy with aniridia, polar cataract, and lens subluxation along with neuropsychomotor and speech delays. Karyotype evaluation showed an interstitial deletion including region 11p13-p14, confirming the diagnosis of WAGRO syndrome. In cases of aniridia, a diagnosis of WAGRO syndrome should be considered.

RESUMO A aniridia é uma doença ocular congênita com grau variável de hipoplasia ou ausência do tecido da íris. É causada pela perda de função do gene PAX6 e pode ser uma anormalidade ocular isolada ou parte de uma síndrome. WAGRO refere-se a uma condição genética rara que leva ao tumor de Wilms, aniridia, anomalias geniturinárias, déficit intelectual e obesidade e é causada por uma deleção do braço curto do cromossomo 11 (11p), onde o gene PAX6 está localizado. Aqui, nós relatamos um menino de 8 anos de idade com aniridia, catarata polar e subluxação do cristalino, além de retardo neuropsicomotor e de fala. A avaliação cariotípica revelou uma deleção intersticial envolvendo a região 11p13-p14, confirmando o diagnóstico da síndrome WAGRO. Em casos de aniridia, um diagnóstico de síndrome de WAGRO deve ser considerado.

Clinical and Molecular Characterization of Adult Glioblastomas in Southern Brazil.

We investigated 113 adult Brazilian patients with glioblastoma (GBM) for comparison with patients from distinct geographical areas and evaluation of suitability for novel targeted therapies. Patients were assessed for clinical features and tumor genomic characteristics such as ROS1 and NTRK1 rearrangements, KIT, PDGFRA, and KDR amplification, and RB1 deletion using multicolor fluorescence in situ hybridization. The majority of patients were male (53%), over 40 years (94%), with tumor located in single site (64%), in the right cerebral hemisphere (60%), and underwent partial resection (71%); 14% presented complications after surgery. The main clinical sign at diagnosis was focal abnormality (57%); frontal (31%); and temporal (20%) regions were most commonly affected. Median hospitalization time was 20 days, median survival was 175 days. One tumor was positive for rearrangement in NTRK1 and another in ROS1 (0.9% each). PDGFRA was amplified in 20% of cases, often co-amplified with KDR (>90%) and KIT (>60%). RB1 was deleted in 16% of patients. There was no association between these molecular abnormalities and patient survival. However, older age, complications after surgery, and right-sided tumors were independent variables associated with patient survival. This study contributes information on the molecular profile of glioblastomas in Latin America possibly supporting new target therapies.

SIBLINGS AFFECTED BY ECTRODACTYLY-ECTODERMAL DYSPLASIA AND CLEFT LIP/PALATE (EEC) SYNDROME PRESENTING NORMAL PARENTS: GERMLINE MOSAICISM? / IRMÃOS AFETADOS PELA SÍNDROME DE ECTRODACTILIA, DISPLASIA ECTODÉRMICA E FISSURA LABIOPALATAL (EEC) COM PAIS HÍGIDOS: MOSAICISMO GERMINATIVO?

OBJECTIVE: EEC is an acronym for an autosomal dominant syndrome clinically characterized by ectrodactyly (E), ectodermal dysplasia (E) and cleft lip/palate (C). Our aim was to describe a rare case of siblings affected by ectrodactyly, ectodermal dysplasia and cleft lip/palate (EEC) syndrome presenting normal parents. CASE DESCRIPTION: The patient was the third son of young and healthy parents. The parents did not present any minor or major anomaly of hands, feet or skin, hair and teeth. The couple had a previous history of two children with hands and feet malformations similar to the present patient. The first was a stillborn, and the second one a preterm infant that died in the first days after birth due to the consequences of prematurity. After birth, the patient presented respiratory distress with need of endotracheal intubation and mechanic ventilation. At physical examination, there were cleft lip/palate, hands and feet ectrodactyly, with absence of the second and third fingers in both hands, and reduction defects affecting mainly the second toes. The child presented pneumothorax and cardiorespiratory arrest and died at 1 month and 26 days. COMMENTS: Herein we described a case of siblings with EEC syndrome, indicative of a germline mosaicism. In the literature review, there was the description of only three similar reports. The present case strengthens the possibility that germline mosaicism may be a more common inheritance mechanism than previously thought in cases of EEC syndrome.

OBJETIVO: EEC é um acrônimo para uma síndrome autossômica dominante caracterizada clinicamente por ectrodactilia (E), displasia ectodérmica efissura labiopalatal (C). Nosso objetivo foi relatar um caso raro de irmãos afetados pela síndrome de ectrodactilia, displasia ectodérmica efissura labiopalatal (EEC) com pais hígidos. DESCRIÇÃO DO CASO: O paciente era o terceiro filho de pais jovens e hígidos, os quais não apresentavam nenhuma anomalia menor ou maior de mãos e pés ou anomalias de pele, cabelos e dentes. O casal tinha história prévia de duas crianças com malformação de mãos e pés, similar à do paciente. O primeiro foi natimorto e o segundo, prematuro, falecendo nos primeiros dias de vida, pelas consequências da prematuridade. Após o nascimento, o paciente apresentou desconforto respiratório, com necessidade de intubação orotraqueal e ventilação mecânica. No exame físico, verificaram-se a presença de fissura labiopalatal e ectrodactilia de mãos e pés, com ausência do segundo e terceiro dedos em ambas as mãos e defeitos de redução acometendo principalmente o segundo dedo dos pés. A criança apresentou pneumotórax e parada cardiorrespiratória, morrendo com 1 mês e 26 dias de vida. COMENTÁRIOS: Descrevemos aqui um caso de irmãos com síndrome EEC, indicativo de mosaicismo germinativo. Na revisão da literatura, observaram-se apenas três relatos similares. Este caso reforça a possibilidade do mosaicismo germinativo ser um mecanismo de herança mais comum do que se acreditava previamente para casos da síndrome EEC.
