RESUMEN

ABSTRACT Objective: To perform a systematic literature review to analyze existing data on the neurological effects of coronavirus on newborns. Data sources: We followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P), and searched the PubMed and Embase platforms for the keywords [brain damage OR pregnancy OR developmental outcomes] and [coronavirus OR SARS-CoV-2 OR SARS-CoV OR MERS-CoV] between January 1, 2000 and June 1, 2020. Data synthesis: Twenty-three reports described the course of pregnant women exposed to SARS-CoV-2, SARS-CoV, or MERS-CoV during the gestational period, eight to SARS-CoV-2, eight to SARS-CoV, and seven to MERS-CoV. No data were found on abnormalities in brain development or on a direct link between the virus and neurological abnormalities in the human embryo, fetus, or children. Spontaneous miscarriage, stillbirth, and termination of pregnancy were some complications connected with SARS/MERS-CoV infection. SARS-CoV-2 is not currently associated with complications in the gestational period. Conclusions: The literature has no data associating exposure to coronavirus during pregnancy with brain malformations and neurodevelopmental disorders. However, despite the lack of reports, monitoring the development of children exposed to SARS-CoV-2 is essential given the risk of complications in pregnant women and the potential neuroinvasive and neurotropic properties found in previous strains.


RESUMO Objetivo: Realizar uma revisão sistemática da literatura para analisar os dados existentes sobre os efeitos neurológicos do coronavírus em recém-nascidos. Fontes de dados: Esta revisão seguiu as diretrizes dos Principais Itens para Relatar Revisões Sistemáticas e Meta-Análises (Preferred Reported Items for Systematic Review - PRISMA) e dos Protocolos dos Principais Itens para Relatar Revisões Sistemáticas e Meta-Análises (Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols - PRISMA-P), pesquisando as plataformas PubMed e Embase pelas palavras-chave [brain damage (dano cerebral) OU pregnancy (gravidez) OU developmental outcomes (alterações de desenvolvimento)] e [coronavirus (coronavírus) OU SARS-CoV-2 OU SARS-CoV OU MERS-CoV] entre 1º de janeiro de 2000 e 1º de junho de 2020. Síntese dos dados: Vinte e três relatos descreveram a evolução de mulheres grávidas expostas ao SARS-CoV-2, SARS-CoV ou MERS-CoV durante o período gestacional, oito ao SARS-CoV-2, oito ao SARS-CoV e sete ao MERS-CoV. Não foram encontrados dados sobre anormalidades no desenvolvimento cerebral ou sobre uma ligação direta entre o vírus e alterações neurológicas no embrião, feto ou crianças. Abortamento espontâneo, morte fetal e interrupção da gravidez foram algumas das complicações relacionadas à infecção por SARS/MERS-CoV. Até o momento, o SARS-CoV-2 não está associado a complicações no período gestacional. Conclusões: Não há dados na literatura que associem a exposição ao coronavírus durante a gravidez com malformações cerebrais e distúrbios do neurodesenvolvimento. No entanto, apesar da falta de relatos, o monitoramento do desenvolvimento de crianças expostas ao SARS-CoV-2 é essencial devido ao risco de complicações em gestantes e às potenciais propriedades neuroinvasivas e neurotrópicas encontradas em cepas anteriores.

RESUMEN

IMPORTANCE: Congenital Zika syndrome virus infection is said to interfere in children's development. OBJECTIVE: evaluate gross motor trajectories and the frequency of cerebral palsy in children with congenital Zika syndrome. DESIGN: Cohort study applying the Alberta Infant Motor Scale (AIMS) and the Bayley III Scales in infants from 6 to 18 months of age. SETTING: The SARAH network, Rio de Janeiro. PARTICIPANTS: Thirty-nine infants whose diagnoses were established through clinical history, serology tests, and neuroimaging findings. Main outcomes and measures: Congenital Zika syndrome is associated with severe motor delays and is a risk factor to the diagnosis of cerebral palsy. RESULTS: The Alberta Infant Motor Scale mean raw score at 6 months was 9.74 (SD 4.80) or equivalent to 2 to 3 months of motor developmental age. At the age of 12 months, 14.13 (SD 11.90), corresponding to 3 to 4 months of motor development age; the Bayley III Scales results correlated to the Alberta Infant Motor Scale ( P < .001) at this age. At 18 months, 15.77 (SD 13.80) or a motor development equivalent to 4 to 5 months of age. Thirty-five of 39 children (89.7%) met criteria for the diagnosis of cerebral palsy. Conclusions and relevance: Gross motor development marginally progresses from 6 to 18 months of age. These individuals also displayed a high frequency of cerebral palsy.

RESUMEN

The recent alarming statements concerning the newborn ZIKV-induced microcephaly epidemics in the Northeast of Brazil, released by the Brazilian Ministry of Health, as well as important international health agencies, such as the World Health Organization and the Pan American Health Organization, raised many "why and how" questions so far, that will hopefully be scientifically answered, as more researches in that regard come up in the long term. In this paper, we describe another potentially ZIKV-induced central nervous system and musculoskeletal disorder that has accompanied microcephaly in these children: atrhogryposis multiplex congenita. The goal is to bring up some hypotheses for possible underlying molecular mechanisms based on published data taken from animal models, such as ovine and cattle, which once infected by other types of arboviroses and viruses that also belong to the Flaviviridae family, presented, too, with the full-blown CNS spectrum of malformations at birth.

RESUMEN

BACKGROUND: Autism Spectrum Disorders (ASD) now encompass a broad heterogeneous group of people who present in the early developmental years with a wide range of social and communication deficits, which are typically also associated with complex repetitive behaviors and circumscribed interests. The target goal is to heighten readers' perception into the trend to personalize the distinct autistic and related developmental conditions encompassing the 12p region. CASE PRESENTATION: This is a case-report of a 4-year-old male who presented the core signs of ASD, which were thought to be related to a rare 12p13.2 deletion.  We further reviewed the literature in order to outline the related developmental conditions in the 12p region. Aside from this patient reported here, we found an additional number of 43 cases described in the medical literature since 1974, that have been related to deletions in the 12p region. However, to the best of our knowledge, none of the previous had been specifically linked to the 12p13.2 band. CONCLUSIONS: The 12p deletion spectrum is rarely described as part of the selective genotypes thought to be related to ASD. Even inside of a small piece of the puzzle, there might be ample variation in the behavioral and clinical phenotypes of children and adults presenting with this particular genetic profile. In that regard, the particular 12p13.2 distal deletion presentation is one of the possible genotypes encompassed by the "12p deletion spectrum syndrome", that might be potentially connected to the diagnosis of ASD and related developmental disorders.

RESUMEN

BACKGROUND: Global developmental delay, lack of speech, and severe epilepsy are the characteristic hallmarks of Angelman syndrome (AS). The purpose of this study was to explore the utility of brain magnetic resonance imaging (MRI) as an ancillary tool for the diagnosis of AS. MATERIAL AND METHODS: Brain MRI images of nine laboratory-confirmed patients with AS from a neurorehabilitation center in Rio de Janeiro were reviewed. Each MRI was assessed by a set of two experienced neuroradiologists following a predefined protocol. RESULTS: The main neuroimaging findings revealed in our study were: Thinning of the corpus callosum in five patients; enlargement of lateral ventricles in four patients; and, cerebral atrophy with frontal and temporal predominance in one patient. All patients presented with an increased signal intensity in T2-weighted images and fluid-attenuated inversion recovery (FLAIR) sequences. CONCLUSION: The lack of specific changes in the brain MRI of children with AS observed in this case series rendered brain MRI a less helpful complementary test. Thus, a definitive diagnosis of AS could only be established on molecular biology that was undertaken based on the clinical suspicion of AS.

RESUMEN

Angelman syndrome is a neurogenetic disorder that severely affects global neurodevelopment due to modifications in the structure or functioning of UBE3A gene. Its prevalence ranges from 1:10,000 to 1:40,000. There are four main genetic types of AS transmission. A maternal deletion in 15q11.2-q13 is the most common type. There are three well-established electroencephalogram (EEG) patterns used as an ancillary tool for AS diagnosis. The main objectives are to scrutinize the EEG patterns in Angelman syndrome, their correlation to different types of seizures and to review the role of the EEG as an ancillary screening tool in the diagnosis of clinically suspected patients. Forty-three patients' charts and their previously recorded EEGs were reviewed. A set of 34 patients with deletion type, paternal uniparental disomy type and imprint defect type AS were enrolled. AS diagnosis was confirmed either by fluorescent in situ hybridization test or Methylation Specific-Multiplex Ligation Probe Amplification test. Sequencing of UBE3A was not available. Frequencies and Chi-square tests were used for statistic analysis. Pattern I type EEG was observed in 22 (64.7 %) individuals. Pattern II accounted for 6 (17.6 %); Pattern III was evident in 11 (32.4 %). The three distinguished EEG patterns, more frequently Pattern I, when observed in the appropriate clinical setting, may heighten the index of suspicion for selecting patients who will need a molecular biology test to confirm the diagnosis of AS.

RESUMEN

Duchenne and Becker muscular dystrophies (DMD/DMB) are neuromuscular diseases linked to chromosome X and affect mainly male individuals. Duchenne muscular dystrophy is the most severe form of the disease, leading to a decreased patient survival compared with individuals with Becker type and female carriers of the mutated gene. In this paper we present the case of a female adolescent whose clinical picture and disease course closely resembled male individuals.

RESUMEN

OBJECTIVE: To describe the etiologies of West syndrome (WS) among children followed in a rehabilitation center. METHOD: Retrospective study with emphasis in the following items: gender, age at the diagnosis of WS and its etiology. The etiologies were divided into three categories: symptomatic, cryptogenic and idiopathic. Symptomatic cases were classified as follows: pre, post and perinatal. RESULTS: Ninety-five patients were included. Fifty-nine were boys (62%). Mean age at the diagnosis was 4.9 (+/- 5.0) months. There were 25 cryptogenic (26.3%), one idiopathic (1.1%) and 69 (72.6%) symptomatic cases, most of them of perinatal origin. CONCLUSION: Our findings are in agreement with the literature. In the future, as our knowledge in the field of WS and its diagnostic methods increase, there will be a small number of cryptogenic and idiopathic cases.

RESUMEN

OBJETIVO: Descrever as etiologias da síndrome de West (SW) em um grupo de crianças atendidas no ambiente de um centro de reabilitação. MÉTODO: Análise retrospectiva, avaliando-se os seguintes itens: gênero, idade por ocasião da definição do diagnóstico da SW e sua etiologia. Esta foi dividida em três categorias: sintomática, criptogênica e idiopática. Os casos sintomáticos foram divididos em pré, peri e pós-natais. RESULTADOS: Noventa e cinco pacientes foram incluídos, sendo 59 do gênero masculino (62 por cento). A idade do diagnóstico variou entre 1 e 24 meses, com média de 4,9 (±5,0) meses. Vinte e cinco casos foram considerados criptogênicos (26,3 por cento) e apenas um idiopático (1,1 por cento). Os demais foram classificados com sintomáticos (72,6 por cento), sendo predominantemente casos perinatais. CONCLUSÃO: Nossos achados se assemelham aos da literatura. Conforme se ampliam o conhecimento acerca da SW e os métodos complementares de diagnóstico, haverá tendência à diminuição dos casos hoje considerados criptogênicos ou idiopáticos.
