ABSTRACTobjectIve. This systematic review sought to conduct a general analysis of the Brazilian scientific output on autism spectrum disorders (ASD) published between 2002 and 2009. Methods. A literature search was conducted in the scientific databases PubMed, SciELO, and LILACS and in the CAPES portal, using keywords such as "autism" and "pervasive developmental disorders". results. A total of 93 articles were identified, most of which were authored by researchers from Southeast Brazil and affiliated with public universities. Approximately one-third of all articles were published in journals with an impact factor ranging from 0.441 to 3.211; most were based on small sample sizes. Furthermore, 140 theses and dissertations were identified, 82.1% of which were master's theses. Interventions for ASD were the predominant research topic. conclusIon. Brazilian researchers are clearly interested in the topic of ASD; however, a substantial portion of their scientific output is limited to doctoral dissertations or master's theses. A minority of articles was published in journals with a high impact factor. These findings suggest the need for studies with larger sample sizes, which could produce higher-impact findings and thus increase visibility of the Brazilian scientific output in the field of ASD research.
ResumoOs transtornos globais do desenvolvimento (TGD) são caracterizados por anormalidades qualitativas e abrangentes em três domínios do desenvolvimento: interação social recíproca, comunicação e presença de um repertório comportamental de interesses restritos, repetitivo e estereotipado. Estudos genéticos têm identificado a recorrência de TGD numa mesma família. O presente estudo teve por objetivo rastrear a ocorrência de sinais e sintomas de TGD em irmãos de indivíduos com esse diagnóstico. Participaram do estudo 25 sujeitos provenientes de 19 famílias. A coleta de dados foi realizada mediante a utilização da versão brasileira do Autism Screening Questionnaire (ASQ), ou Questionário de Comportamento e Comunicação Social. Foram confirmados dois casos de irmãos com TGD (10,52% dos casos), sendo um irmão gêmeo monozigótico e um irmão de um probando com diagnóstico de síndrome de Asperger. Os dados apontam para taxas mais elevadas do que aquelas descritas na literatura (2-6%) e se aproximam dos achados que relatam 10% de recorrência familiar em gêmeos dizigóticos. Esse resultado fornece evidências de possíveis fatores neurogenéticos para explicar a ocorrência de TGD nos familiares dos probandos estudados e salienta a necessidade de efetuar o rastreamento desse transtorno não só na criança avaliada, mas também em seus irmãos. Descritores: Irmãos, genética, transtornos do espectro do autismo. AbstractPervasive developmental disorders (PDD) are characterized by comprehensive and qualitative abnormalities affecting three areas of development: reciprocal social interaction, communication, and a repetitive, stereotyped behavioral repertoire, of limited interests. Genetic studies have identified the recurrence of PDD in the same family. The present study aimed to trace the occurrence of signs and symptoms of PDD in the siblings of patients with this diagnosis. The study included 25 subjects from 19 families. Data collection was performed using the Brazilian version of the Autism Screening Questionnaire (ASQ). Two cases of PDD in siblings were confirmed (10.52% of cases): a monozygotic twin brother and the brother of a proband with a diagnosis of Asperger syndrome. Our data indicate higher rates of PDD in siblings than described in the literature (2-6%), close to the findings that suggest a 10% rate of familial recurrence in dizygotic twins. This result provides evidence of possible neurogenetic factors to explain the occurrence of PDD in relatives of the probands assessed and underscores the need to screen not only the child under evaluation, but also their siblings.
This article is focused on problems in the area of Developmental Psychology, regarding the understanding of the implications of the use of social networks by children in physical, psychosocial and cognitive development, in second and third childhood. The theme was addressed through an integrative bibliographical review, through which it was possible to understand aspects of human development, how children access social networks and how this implies development. According to the studies carried out, it was found that more and more children are present in the digital world, being exposed to different ways of expressing themselves, relating, communicating and interacting with different themes. In terms of access to social networks, it was found that the most accessed by this age group are Youtube, WhatsApp, Youtube Kids and Netflix. During the research, it was noticed impacts on the development of motor skills, physical imbalance, synesthetic experiences, melatonin production, identity construction, self-esteem, communication, control of emotions, learning process, memory and language development. Finally, in view of the different possible impacts on the child's development, recommendations were found for the time of exposure to screens in different age groups and also the need for guardians to monitor children's access to the digital environment.
