ABSTRACT

Background: Facial expressions transmit information about emotional state, facilitating communication and regulation in interpersonal relationships. Their acute recognition is essential in social adaptation and lacks among children suffering from autism spectrum disorders. The aim of our study was to validate the "Recognition of Facial Emotions: Tunisian Test for Children" among Tunisian children in order to assess facial emotion recognition in children with autism spectrum disorders (ASD). Methods: We conducted a cross-sectional study among neurotypical children from the general population. The final version of or test consisted of a static subtest of 114 photographs and a dynamic subtest of 36 videos expressing the six basic emotions (happiness, anger, sadness, disgust, fear and surprise), presented by actors of different ages and genders. The test items were coded according to Ekman's "Facial Action Coding System" method. The validation study focused on the validity of the content, the validity of the construct and the reliability. Results: We included 116 neurotypical children, from 7 to 12 years old. Our population was made up of 54 boys and 62 girls. The reliability's study showed good internal consistency for each subtest: the Cronbach coefficient was 0.88 for the static subtest and 0.85 for the dynamic subtest. The study of the internal structure through the exploratory factor analysis of the items of emotions and those of intensity showed that the distribution of the items in sub-domains was similar to their theoretical distribution. Age was significantly correlated to the mean of the overall score for both subtests (p < 10-3). Gender was no significantly correlated to the overall score (p = 0.15). High intensity photographs were better recognized. The emotion of happiness was the most recognized in both subtests. A significant difference between the overall score of the static and dynamic subtest, in favor of the dynamic one, was identified (p < 10-3). Conclusion: This work provides clinicians with a reliable tool to assess recognition of facial emotions in typically developing children.

ABSTRACT

BACKGROUND: In order to better understand the deployment of the theory of mind (ToM) in Tunisian neurotypical children, we have developed a new tool of assessment of the ToM called the "Tunisian Social Situations Instrument" (TSSI). We opted for the creation of this test in view of the intercultural differences in the development of social skills. Our purpose was to validate this tool in general pediatric population. METHODS: It was a cross-sectional evaluative study that aimed to validate the TSSI in the general pediatric population. We initially conducted a beta test and a pre-validation study before taking the initial version of the TSSI on 123 neurotypical children. Then, we followed the typical validation procedure: appearance validity, content validity, construct validity, and reliability study. RESULTS: Regarding the validity of appearance, the TSSI was comprehensible and adapted to the Tunisian pediatric population. About content validity, the exploratory factor analysis extracted 6 factors that explain 69.3% of the total variance. These factors were respectively social clumsiness types 1 and 2, intention attribution, emotional ToM, epistemic ToM, and simple comprehension questions. The subdomains of social clumsiness (types 1 and 2) and emotional ToM had a Cronbach alpha higher than 0.8. This factor structure as well as the significant inter-correlation between subdomains and the global score were in favor of a good construct validity. The internal consistency study showed good reliability of the final version of the TSSI (alpha of Cronbach at 0,809). Regarding the performance of children at the TSSI, we have noticed a significant association between the global score, age, and verbal intelligence. CONCLUSION: This work offers valuable insights about ToM and provides clinicians with a reliable tool to assess social clumsiness and emotional ToM in typically developing children.

ABSTRACT

BACKGROUND: Based on the recognized principles of assessment of autistic disorders, the child and adolescent psychiatry department in Razi Hospital developed, in coordination with the department of neurology of Razi Hospital and the department of genetics of Charles Nicolle's Hospital an assessment unit for autism spectrum disorders. OBJECTIVE: To describe the clinical characteristics in terms of severity and comorbidities of children assessed for autism spectrum disorders. METHODS: We compiled data about clinical examination of autistic symptoms using the Autism Diagnostic Interview Revised (ADI-R) and the Childhood autism Rating Scale (CARS). Each child developmental age was determined using the Psycho Educative Profile (PEP-R). Neurological examination completed with electroencephalography and genetics testing (caryoptype and X fragile) were performed. RESULTS: Fifty-two children were included in our study. The mean age was 6.6 years with a sex ratio of 6.5. The severity of the clinical presentations was assessed through the following score means: CARS 35, ADI-B: 20, ADI-C: 13, ADI-D: 7, functional developmental age: 2.4 years. Comorbidity with epilepsy was present in 7% of cases and an intellectual disability was found in 80% of them. Genetic tests were normal. CONCLUSION: Our results will be discussed in the light of international recommendations.

ABSTRACT

OBJECTIVES: To investigate the link between pain sensitivity in autism spectrum disorders (ASD) and self-aggressive behavior. METHODS: we performed a cross-sectional study which involved 50 children fulfilling DSM-V criteria for ASD; confirmed by the Autism Diagnostic Interview Revised. The severity of autism was determined using the Childhood Autism Rating Scale (CARS).The psycho-educational profile (PEP-R) was used to assess the age of development and perception.  Sensitivity to pain was assessed with item IX of the CARS. Self-aggressive behavior was assessed by the Behavior Problems Inventory. RESULTS: Pain sensitivity was lowered in 40% and elevated in 4% of children. In the univariate analysis, no statistically significant association was found between normal sensitivity or hyper sensitivity to pain and the presence of auto-aggressiveness. A significant association was found between the presence of hypo-sensitivity to pain and the following variables: auto-aggression (p = 0.007, OR = 5.8, 95% CI = 1.5-21) , frequency of self-aggression (p = 0.001), intensity of self-aggression (p = 0.05), location of auto-aggressiveness at head and (P = 0.007, OR = 7.6, 95% CI = 1.8-14), higher score at CARS, and lower perception score at PEP-R (p = 0.012). Multiple-varied analysis identified risk factors for hypo-sensitivity to pain: lower perceptual score (p = 0.003, adjusted OR = 4.3, 95% CI = 1.9-54) and location of self-aggression at head and hands (p = 0.001, adjusted OR = 1.09, 95% CI = 1.02-1.09). CONCLUSION: It would be interesting to develop tools allowing a fine and precise evaluation of the painful sensation.

ABSTRACT

Background - Based on the recognized principles of assessment of autistic disorders, the child and adolescent psychiatry department in Razi Hospital developed an assessment unit with diagnostic as well as therapeutic roles. The aim of this work was to examine its functioning and to analyze the parents' perceptions about the unit services. Methods - We gathered the parental satisfaction about the unit by the means of a hetero-questionnaire. Results - Fifty-two parents of children evaluated within the unit were included.  Patients had received the diagnosis of Autistic Disorder, Pervasive Developmental Disorders Not Otherwise Specified and Asperger Syndrome in accordance with DSM IV criteria, and than that of Autism Spectrum Disorder after DSM 5 publication. The overall satisfaction rate was 63%. Most parents (84.6%) rated the Psycho Educative Profile examination positively, 75% appreciated the neurological examination and the final report steps, 55.8% appreciated step of the Autism Diagnostic Interview revised and 42.3% the genetic exploration. 67% of the parents reported an improvement of their child following the evaluation. This improvement was attributed to the unit in 57.7% of cases. Parents whose children did not have associated disorders such as intellectual disability (p = 0.02), aggressive behavior (p = 0.04), affective disorder (p = 0.01) and sleep-related disorders (p = 0.03) were the most satisfied. Parents of children with epilepsy comorbidity were the least satisfied (p <10-3). 96% of parents suggested repeating the assessment once a year. Conclusion - Assessment units are based on international recommendations. However, it would be interesting to adapt assessments and orientation to the parents' expectations.

ABSTRACT

Simpson-Golabi-Behmel syndrome (SGBS) is an X-linked condition characterized by pre and post natal overgrowth, facial malformations, and visceral, skeletal, and neurological anomalies. The physical characteristics of SGBS have been well documented; however there is a lack of description regarding the behavioral phenotype. We report the case of a 6-year-old boy, with confirmed deletion of 6-8 exons of the glypican-3 gene (GPC3) who presents three distinctive findings: the persistence of the craniopharyngeal canal, an immune-allergic specificity, and a scarcely behavioral phenotype consisting in the association of Austim Spectrum Disorder with accompanying mild intellectual disability and language impairments. He also fulfilled the criteria of Attention Deficit Hyperactivity Disorder and Oppositional Defiant Disorder according to DSM 5 criteria. The specificities of the case are discussed in the light of recent pathophysiological data.
