Brief Report: Early VEPs to Pattern-Reversal in Adolescents and Adults with Autism.

Autism spectrum disorder (ASD) is characterized by atypical visual perception both in the social and nonsocial domain. In order to measure a reliable visual response, visual evoked potentials were recorded during a passive pattern-reversal stimulation in adolescents and adults with and without ASD. While the present results show the same age-related changes in both autistic and non-autistic groups, they reveal a smaller P100 amplitude in the ASD group compared to controls. These results confirm that early visual responses are affected in ASD even with a simple, non social and passive stimulation and suggest that they should be considered in order to better understand higher-level processes.

[Theoretical and practical aspects of cognitive remediation in intellectual disabilities: Relevance of the Cognitive Remediation Therapy program (CRT)]. / Aspects théoriques et pratiques de la remédiation cognitive dans la déficience intellectuelle du jeune adulte : La « Cognitive Remediation Therapy ¼ (CRT) peut-elle être adaptée ?

INTRODUCTION: Teenagers and adults with intellectual disabilities are nowadays "over-handicapped", often due to lack of care in self-sufficiency and continued learning, two essential domains for living in a community. Their cognitive limits, particularly on the executive functions, could be an obstacle to their involvement in the daily life activities, through their difficulties to plan, anticipate, shift and maintain information in working memory. These high level mental functions can be taught with the CRT program (Cognitive Remediation Therapy - Wykes and Reader 2005) developed in other pathologies and providing an adaptation regarding the developmental level of the person. METHODS: Firstly, it is essential to determine cognitive developmental levels of the teenager or the adult, using standard tools, such as Wechsler scales. Secondly, functional and/or adaptative levels have to be assessed using specific tools, such as the Vineland Adaptative Behavior Scale 2nd Edition (VABS-II, Sparrow et al., 2005) and the Functional Intervention Scale (EFI, Willaye et al., 2005). Finally, in order to clearly distinguish what are the preserved and impaired cognitive domains, standard tools assessing executive functions such as the Wisconsin Card Sorting Test, the Tower of London, Stroop Test and BADS are used if possible for the patient. The setting of cognitive remediation programs, previously developed for schizophrenic patients, requires adaptation for teenagers and adults with intellectual disabilities, taking into account the limitation of their cognitive abilities. In this paper, we will show that the CRT method for cognitive remediation is particularly relevant for subjects with intellectual disabilities. This method is hence focused on strategies and exercises to improve working memory, categorization and moreover executive functions. Of course this method might need adaptations, with examples based on simplification of the different tasks, notably for verbal materials, and with variations of the media used. These sessions will be part of a wider individualized caring project, allowing the person to transfer the cognitive acquisitions to his/her daily life. CONCLUSION: The use of cognitive programs adapted to people with intellectual disabilities can provide benefits in the development of autonomy and daily life activities, leading to a better quality of life and self-esteem.

The prevalence of sensitization to lupin flour in France and Belgium: a prospective study in 5,366 patients, by the Allergy Vigilance Network.

OBJECTIVES: To determine the prevalence of sensitization to lupin flour in patients consulting allergists, in order to evaluate the risk of primary and secondary allergies to lupin. METHODS: A prospective study carried out by members of the Allergy Vigilance Network, using prick-tests with a commercial lupin flour extract in patients with various allergic symptoms. The study design classified patients into four groups: peanut allergy, current atopic disease, latent atopy, no atopy. Data were collected and analysed by Network coordinators. RESULTS: Over a two-month period, 88 French and Belgian allergists tested 5,366 patients: 2,680 children and 2,686 adults aged over 16 years. Of the 2,680 children, 11.15% presented with peanut allergy. The frequency of cross-reactivity with lupin was 17.1% for patients with peanut allergy, 2.5% for children with current atopic disease and 1.7% for healthy children with latent atopy. In the 2,686 adults, peanut allergy was diagnosed in 1.86% of patients with cross-reactivity to lupin in 14.6%. Sensitization to lupin was detected in 3.7% of patients with current atopic disease and in 1.8% of those with latent atopy. CONCLUSION: The relative frequency of latent sensitisation to lupin in patients of all ages presenting with atopic disease is a new factor indicating the likelihood of an increase in primary food allergies to lupin flour. This justifies the recent decision requiring mandatory labelling of lupin, and shows the need to inform consumers who may be unaware that this ingredient is being used increasingly. Sensitization to lupin should be searched by prick-tests in any case of peanut allergy. Prick-test to lupin may be valuable whenever a food allergy is suspected when no current food allergens have been identified.
