Usability Evaluation and User Acceptance of Mobile Applications for Saudi Autistic Children

<p class="Body">The evolution of mobile technologies in learning, has been increased the requirements for developing appropriate usability model to fall into the same line with mobile learning applications. Usability of mobile learning applications is a topic that is into research, this paper focuses a tailored designed model called (M-UTUAT) mobile usability model that combines People at the Centre of Mobile Application Development (PACMAD) and the unified theory of acceptance and use of technology (UTAUT) to form a more robust model. As an addition to the usability research, an application (ICT) was developed for children with speech delays and children diagnosed with autism spectrum. The application is a mobile/tablet-based application that developed according to mobile usability measures to get the maximum learning skills and abilities to help autistic children. It has been designed according to the needs of the children specific to their category and skills. The autism spectrum is a broad spectrum with high and low disabilities. The application consists of both visual and audio aids to help children feel comfortable and associate objects more easily with their original meaning and connections. (PECS) is one of the most common techniques that have been clinically proven to be effective in such cases. This application helped an individual with autism spectrum as well as children with speech delays or disabilities to communicate and correlate faster and easily. The application can help so many families by constructing a more communicative path for people with disabilities. The application is innovative that it developed in the Arabic language to serve Arabic learners as most of the autistic applications available serve English learners. Results gathered after questionnaire highlight the usability issues with the (ICT) application. We developed an app to overcome usability issues.</p>

А clinical case of WAGRO syndrome

WAGRO syndrome is a rare genetic syndrome that includes Wilms tumor, aniridia, genitourinary system abnormalities, mental retardation, and obesity. The syndrome is associated with deletions of the short arm of chromosome 11 (11p), where the PAX6 and WT1 genes are located. We present the clinical case of a 7-year-old boy with aniridia, polar cataract, and concomitant neuromotor, psychomotor, and speech delays. Evaluation of the childs karyotype followed by confirmation using multiplex ligation-dependent probe amplification showed the presence of a deletion including in the 11p13-p14 region.

Optimization of Speaking Ability in Early Childhood

abstract :Speech ability is a person's ability to express, convey, express and say something that is in someone's thoughts and feelings. The ability to speak has an important role in the success of socializing someone, because through speaking skills one can communicate and interact with people around him. This study aims to minimize speech delays in early childhood by optimizing learning in early childhood by stimulating children through learning media and adding literature to improve speaking skills in early childhood.

Utility of Magnetic Resonance Imaging (MRI) in Children With Strabismus

Purpose: Magnetic resonance imaging (MRI) of the brain can provide valuable information about structural abnormalities in strabismus. The aim of this study was to evaluate the utility of MRI in this regard and to identify risk factors for abnormal MRI results in children with strabismus. Methods: A retrospective analysis of children <18 years of age presenting with strabismus, who underwent brain MRI at Pusan National University Hospital (Busan, Korea) between January 2012 and March 2017, was performed. Clinical characteristics, MRI results, and ophthalmologic findings were reviewed. Findings were classified as normal or abnormal according to MRI results. Additionally, patients were divided according to age to compare characteristics of infantile and childhood strabismus. Results: A total of 90 patients (47 [52.2%] male, 43 [47.8%] female; mean age, 2.19 ± 0.53 years) were enrolled. Of those, 64 (71.1%) presented with normal and 26 (28.9%) with abnormal MRI results. The age at presentation was lower and abnormal findings on fundus examination were more common in the abnormal MRI group ( P = .002 and P = .008, respectively). Among the patients, 46 (51.1%) had infantile strabismus and 44 (48.9%) had childhood strabismus. Global developmental delays, speech delays, and MRI abnormalities were more common in patients with infantile than in those with childhood strabismus. Ptosis and headaches were more common in patients with childhood strabismus ( P = .025, P = .025, respectively). Conclusion: Brain MRI was helpful for accurate diagnosis and treatment of strabismus in younger children, those with abnormal findings on fundus examination, and infants with developmental, especially speech, delays.
