Task-related social behavior in children with Down syndrome.

The specificity and stability of task-related social behaviors in children ages 5 to 12 was examined. Social behaviors during solvable and unsolvable puzzles were compared among children with Down syndrome, children with mental retardation, and typically developing children matched on mental age (MA). Compared to children without Down syndrome, those with the disorder looked to an adult and requested help more frequently. They also took longer to complete the tasks. These findings suggest that the overuse of social behaviors observed in young children with Down syndrome remains stable over the early school years and are specific to children with Down syndrome.

Emotion recognition by children with Down syndrome.

In three studies, children with Down syndrome were presented with emotion recognition tasks designed to tap their knowledge of simple emotions, their ability to label emotions, and their understanding of emotions from simple, story-based contexts. Results indicate that young children with Down syndrome perform similarly to typical controls matched on MAs of approximately 3 years. However, by developmental age of 4 years, children with Down syndrome performed worse than both MA-matched typical children and children with non-Down syndrome types of mental retardation. Although the MAs of children with Down syndrome increased over 2-years, their emotion recognition abilities did not. Taken together, findings suggest both etiological and developmental differences in the emotion recognition abilities of children with Down syndrome.

Linking variation in the structure and process of bedside glucose testing programs with patient outcomes.

OBJECTIVE: The objective of this study was to determine if variation in compliance to standards listed in Ancillary (Bedside) Blood Glucose Testing in Acute and Chronic Care Facilities (ABBGT) was linked to variation in patient outcomes. DESIGN AND SETTING: A retrospective analysis examined 450 hospitalized patients with a diagnosis of diabetes from three hospitals with high, medium, and low assessment scores for compliance with ABBGT guidelines. Patients with a diagnosis of diabetes without surgical interventions or intensive care unit stays were selected for the study. MAIN OUTCOMES MEASURED: percent bedside glucose tests that were out of normal range and length of stay. RESULTS: Compliance with ABBGT guidelines explained the variation for out of range bedside glucose tests---1.4% and length CONCLUSION: Within a narrow range and high level of compliance with ABBGT guidelines, the compliance scores had a small effect upon the selected outcomes. The hypothesis that following ABBGT guidelines improves patient outcomes was neither proven nor disproven with this study.

Atypical cutaneous lymphocytic infiltrate and a role for quantitative immunohistochemistry and gene rearrangement studies.

AIM: To help clarify the significance of the T-cell receptor (TCR) gene rearrangement and its relationship to the immunophenotyping of histologically atypical cutaneous T-cell lymphoid infiltrates (ACLIs). MATERIALS AND METHODS: One hundred and twenty-four patients presented with lesions clinically suspicious for cutaneous T-cell lymphoma (CTCL). The average age was 55.8 years with a mean follow-up duration of 26.2 months. Cases were classified as malignant (64 cases), inflammatory dermatosis (28 cases), and indeterminate (32 cases), based on follow-up data and histopathology. Quantitative immunophenotyping with computer-assisted imaging was performed using immunohistochemical stains of anti-CD3, CD4, CD5, CD7, CD8, CD20, CD30, CD56, CD68, Bcl-2, p53, and proliferating cell nuclear antigen (PCNA). RESULTS: Abnormal immunophenotypic expression in 87.5% of the malignant cases, including CD4 or CD8 predominance (67%), deletion of pan-T-cell antigens (16.1%), and activation of antigen/oncogene expression (47%), was observed. In addition, 36 clinically malignant cases displayed rearranged bands by polymerase chain reaction (PCR) with TCR beta and gamma. Two benign cases displayed abnormal immunophenotype and two others showed rearranged bands. All of these patients responded to topical steroid therapy with complete resolution. Nineteen indeterminate cases displayed either rearranged bands or immunophenotypic abnormalities, 15 of which were reclassified as malignant. All but three patients improved after CTCL treatment. CONCLUSION: Quantitative immunophenotyping and gene rearrangement analysis can provide detailed information for classifying ACLIs with 91% diagnostic sensitivity and 87% specificity.

Parental perspectives on inclusion: effects of autism and Down syndrome.

This study examined the effects of the child's diagnosis (autism vs. Down syndrome), age, and current educational placement on parental perceptions toward inclusion for their child with disabilities. Parents of children with autism and with Down syndrome completed surveys regarding their opinions on their child's current educational placement, their desire for changing the current placement, and their views on inclusive education. Results indicated that diagnosis, age, and current placement influenced parental opinion on the ideal educational placement for their child. Parents of children with Down syndrome were significantly more likely to endorse inclusion (full-time placement in general education) as the ideal educational program for their child whereas parents of children with autism were more likely to endorse mainstreaming (consistent part-time placement with general education students). Parents of younger children and parents whose children were already placed in general education programs were more positive towards inclusion than parents of older children or students currently in special education. Findings are discussed in terms of child characteristics and prevailing educational practices.
