Autistic spectrum disorders : practical strategies for teachers and other professionals.

El espectro autista, a veces también se conoce como trastorno generalizado del desarrollo, se caracteriza por presentar la persona déficit en la interacción social, la comunicación y en la restricción de actividades e intereses. Se han identificado seis áreas principales en las que los niños con este trastorno tienen más dificultad en las escuelas: comportamiento, aprendizaje y pensamiento, conversación, experiencias sensoriales y motoras, lenguaje y comunicación y habilidades sociales. Este manual ofrece ayuda a los adultos interesados en identificar, comprender la razón de esta conducta particular y da consejos prácticos para cambiar, moderar o administrar estas dificultades dentro de escuelas normales.

Differences between the gut microflora of children with autistic spectrum disorders and that of healthy children

Children with autistic spectrum disorders (ASDs) tend to suffer from severe gastrointestinal problems. Such symptoms may be due to a disruption of the indigenous gut flora promoting the overgrowth of potentially pathogenic micro-organisms. The faecal flora of patients with ASDs was studied and compared with those of two control groups (healthy siblings and unrelated healthy children). Faecal bacterial populations were assessed through the use of a culture-independent technique, fluorescence in situ hybridization, using oligonucleotide probes targeting predominant components of the gut flora. The faecal flora of ASD patients contained a higher incidence of the Clostridium histolyticum group (Clostridium clusters I and 11) of bacteria than that of healthy children. However, the non-autistic sibling group had an intermediate level of the C. histolyticum group, which was not significantly different from either of the other subject groups. Members of the C. histolyticum group are recognized toxin-producers and may contribute towards gut dysfunction, with their metabolic products also exerting systemic effects. Strategies to reduce clostridial population levels harboured by ASD patients or to improve their gut microflora profile through dietary modulation may help to alleviate gut disorders common in such patients.

Mothers' attributions following their child's diagnosis of autistic spectrum disorder: exploring links with maternal levels of stress, depression and expectations about their child's future

Although the impact of autism spectrum disorders (ASDs) on the family is well recognized, the way mothers attempt to make sense of the diagnosis is largely unexplored. However, in other disabilities, attributions have been shown to predict a variety of outcomes including maternal wellbeing and engagement in treatment. Using Weiner's (198S) three-dimensional model, 16 mothers were interviewed to examine the nature and impact of their beliefs about their child's ASD using semi-structured interviews and measures of depression, parenting stress and expectations for their child's future. The findings suggested that mothers made a diverse and complex range of attributions that were consistent with Weiner's dimensions of locus of cause, stability and controllability. The nature of their attributions reflected particular difficulties associated with ASDs, such as uncertainties regarding cause and prognosis. Taking account of mothers' search for meaning will better enable professionals to support families following diagnosis.

Efficacy of three screening instruments in the identification of autistic-spectrum disorders

Background Screening instruments for autistic-spectrum disorders have not been compared in the same sample. Aims To compare the Social Communication Questionnaire (SCQ), the Social Responsiveness Scale (SRS) and the Children's Communication Checklist (CCC). Method Screen and diagnostic assessments on 119 children between 9 and 13 years of age with special educational needs with and without autistic-spectrum disorders were weighted to estimate screen characteristics for a realistic target population. Results The SCQ performed best (area under receiver operating characteristic curve (AUC)=0.90; sensitivity. 6; specificity 0.78). The SRS had a lower AUC (0.77) with high sensitivity (0.78) and moderate specificity (0.67). The CCC had a high sensitivity but lower specificity (AUC=0.79; sensitivity 0.93; specificity 0.46). The AUC of the SRS and CCC was lower for children with IQ < 70. Behaviour problems reduced specificity for all three instruments. Conclusions The SCQ, SRS and CCC showed strong to moderate ability to identify autistic-spectrum disorder in this at-risk sample of school-age children with special educational needs.

A double-blind, placebo-controlled, crossover-designed probiotic feeding study in children diagnosed with autistic spectrum disorders

There is growing interest in the role of gastrointestinal (GI) pathology and clinical expression of autism. Recent studies have demonstrated differences in the faecal clostridial populations harboured by autistic and non-autistic children. The potential of Lactobacillus plantarum WCSF1 (a probiotic) to modulate the gut microbiota of autistic subjects was investigated during a double-blind, placebo-controlled, crossover-designed feeding study. The faecal microbiota, gut function and behaviour scores of subjects were examined throughout the 12-week study. Lactobacillus plantarum WCFS1 feeding significantly increased Lab158 counts (lactobacilli and enterococci group) and significantly reduced Erec482 counts (Clostridium cluster XIVa) compared to placebo. Probiotic feeding also resulted in significant differences in the stool consistency compared to placebo and behaviour scores (total score and scores for some subscales) compared to baseline. The major finding of this work was the importance of study protocol in relation to the specific considerations of this subject population, with an extremely high dropout rate seen (predominantly during the baseline period). Furthermore, the relatively high inter-individual variability observed suggests that subsequent studies should use defined subgroups of autistic spectrum disorders, such as regressive or late-onset autism. In summary, the current study has highlighted the potential benefit of L. plantarum WCFS1 probiotic feeding in autistic individuals.

Securing provision for children with autistic spectrum disorders: the views of parents

An original questionnaire was designed to seek the perspectives of parents about the process of securing appropriate educational provision for their child with autism spectrum disorder. In total, 738 responses were analysed using both quantative and qualitative data. Although a broad range of opinion was evidenced and a clear majority of families were happy with the end decision of placement, most families were significantly less happy with the process to determine that provision. Most families found this process difficult to navigate and frustrating. This caused a high level of stress for a significant proportion of families. Implications for practice are discussed.

Trabalho e atividade: categorias de análise na psicologia histórico-cultural do desenvolvimento

Este artigo é resultado de estudos teóricos e pretende apresentar algumas contribuições ao estudo da psicologia histórico-cultural do desenvolvimento, mais especificamente no que se refere à relação existente entre as categorias de trabalho e atividade. Estudos desta natureza são importantes para psicólogos, pedagogos e demais profissionais envolvidos direta ou indiretamente com a prática educativa, na busca por compreender o problema da periodização do desenvolvimento em uma perspectiva não naturalizante. Nesta direção, a categoria de atividade principal mostra-se central como força motriz do processo de desenvolvimento humano, portanto encontra-se estreitamente ligada ao lugar que cada indivíduo ocupa na sociedade de classes bem como às condições objetivas de sua existência material. O estudo do desenvolvimento coincide com o estudo da pessoa concreta, imersa numa trama de relações sociais e num sistema político e econômico; enfim, outra coisa não é senão o estudo da história objetivada em cada indivíduo particular.

Contribuições da psicologia histórico-cultural para a pedagogia histórico-crítica

This article aims to show elements based on historical-cultural psychology, which are reiterative of historically systematized scientific knowledge transmission as condition of human development and essential function of school education. In that way, it points the sign appropriation as decisive mark in the natural psychic basis overcoming towards to culturally established psychophysical properties formation, characterizing the psychism as an interfuncional system answerable for the constitution of the subjective image of objective reality. In the face of such presuppositions, it firms the role of school education in the mentioned image formation, highlighting the qualitative differences resultant of education based to quotidian and spontaneous concepts, as well as scientific ones. It pleads that the defense of sign quality offered to appropriation by school education is the main intersection point between the historical-cultural psychology and the historical-critical pedagogy.
