The possible role of the cerebellum in autism/PDD: disruption of a multisensory feedback loop.

Autism and pervasive developmental disorder (PDD) are characterized by impairments in socialization and communication, and by restricted and stereotypic patterns of behavior. Associated symptoms or features of autism/PDD include problems with attention and orientation, and an odd response to the environment and sensory stimuli. Persons with autism/PDD can over or under respond or react to sensation. Evidence suggests that there is aberrant brain structure in this disorder, particularly in the cerebellum. This paper will attempt to show a possible relationship between the pathology in the cerebellum and the symptomatology seen in autism/PDD with an emphasis on the sensory issues.

Development and implementation of computerized clinical guidelines: barriers and solutions.

Research indicates that computerized decision support systems (CDSSs) can improve clinical performance and patient outcomes, and yet CDSSs are not in widespread use. Physician guidelines, in general, face barriers in implementation. Guidelines in a computerized format can overcome some of the barriers to conventional text-form guidelines; however, computerized programs have novel aspects that have to be considered, aspects such as technical problems/support and user interface issues that can act as barriers. Though the literature points out that human, organizational, and technical issues can act as barriers in the implementation of CDSSs, studies clearly indicate that there are methods that can overcome these barriers and improve CDSS acceptance and use. These methods come from lessons learned from a variety of CDSS implementation ventures. Notably, most of the methods that improve acceptance and use of a CDSS require feedback and involvement of end-users. Measuring and addressing physician or user attitudes toward the computerized support system has been shown to be important in the successful implementation of a CDSS. This article discusses: 1) the barriers of implementation of guidelines in general and of CDSSs; 2) the importance of the physician's role in development, implementation, and adherence; 3) methods that can improve CDSS acceptance and use; and 4) the types of tools needed to obtain end-user feedback.

Effectiveness of N,N-dimethylglycine in autism and pervasive developmental disorder.

N,N-dimethylglycine, a dietary supplement, has been reported to be beneficial in children with autism and pervasive developmental disorder. We examined the effectiveness of dimethylglycine in children with autism and pervasive developmental disorder in a double-blind, placebo-controlled study. Thirty-seven children between 3 and 11 years of age with a diagnosis of autism and/or pervasive developmental disorder were gender and age matched and randomly assigned to receive either placebo or dimethylglycine for 4 weeks. All children were assessed before and after treatment on two behavioral measures, the Vineland Maladaptive Behavior Domain and the Aberrant Behavior Checklist. Standardized neurologic examinations before and after treatment on 33 children showed no change. An overall improvement on all behavioral measures was observed for both the placebo and the dimethylglycine groups. However, the improvement among the children who received dimethylglycine was not statistically different from the improvement observed among the children who received the placebo. The children who participated in this study were a heterogeneous group, and their apparent responses to the dimethylglycine varied. Some children appeared to respond positively to the dimethylglycine, and there was a smaller proportion of negative changes in the dimethylglycine group, but the quantitative changes in the dimethylglycine behavioral assessments were not significantly different from what was observed among children who received placebo.

Computerizing medication algorithms and decision support systems for major psychiatric disorders.

In this article, the authors discuss the rationale for the use of computerized medication algorithms and decision support systems in the treatment of major psychiatric disorders. The field of psychopharmacology has advanced tremendously in the last two decades, with the resulting vast array of new information yielding a marked disparity between actual practice and what is commonly called "best practice." As a remedy, clinical practice guidelines and algorithms have been widely developed. These algorithms are used to disseminate up-to-date information, effect change in physician behavior, and reduce untoward variation in care. Review of the literature reveals advantages and limitations in trying to implement these paper and pencil guidelines and algorithms. Available research also suggests that computerized decision support systems have the potential to overcome such limitations, increase the use of treatment guidelines and algorithms, and improve physician adherence to recommended practices. The advantages of computerized medication algorithms and decision support systems are discussed. Finally, the computer platform elements that are necessary to make such systems effective and user-friendly are described.
