Practice procedures in models of primary care collaboration for children with ADHD.

Introduction: With nationwide movement toward an integrated medical home, evidence to support, compare, and specify effective models for collaboration between primary care and behavioral health professionals is essential. This study compared 2 models of primary care with behavioral health integration on American Academy of Pediatrics guideline adherence for attention-deficit/hyperactivity disorder (ADHD) assessment and treatment.

Method: We conducted a retrospective chart review of a random sample of children aged 6-13 years, seen for ADHD services in 2 primary care offices, 1 fully integrated model and 1 co-located service only model, comparing ADHD assessment and treatment practices.

Platelets and smooth muscle cells affecting the differentiation of monocytes.

Background: Atherosclerosis is characterised by the formation of plaques. Monocytes play a pivotal role in plaque development as they differentiate into foam cells, a component of the lipid core whilst smooth muscle cells (SMC) are the principal cell identified in the cap. Recently, the ability of monocytes to differentiate into a myriad of other cell types has been reported.

Advancing genetic testing for deafness with genomic technology.

Background: Non-syndromic hearing loss (NSHL) is the most common sensory impairment in humans. Until recently its extreme genetic heterogeneity precluded comprehensive genetic testing. Using a platform that couples targeted genomic enrichment (TGE) and massively parallel sequencing (MPS) to sequence all exons of all genes implicated in NSHL, we tested 100 persons with presumed genetic NSHL and in so doing established sequencing requirements for maximum sensitivity and defined MPS quality score metrics that obviate Sanger validation of variants.

Pre-capture multiplexing improves efficiency and cost-effectiveness of targeted genomic enrichment.

Background: Targeted genomic enrichment (TGE) is a widely used method for isolating and enriching specific genomic regions prior to massively parallel sequencing. To make effective use of sequencer output, barcoding and sample pooling (multiplexing) after TGE and prior to sequencing (post-capture multiplexing) has become routine. While previous reports have indicated that multiplexing prior to capture (pre-capture multiplexing) is feasible, no thorough examination of the effect of this method has been completed on a large number of samples.

Are fibrocytes present in pediatric burn wounds?

Objective of the study is to investigate for the presence of fibrocytes, a leucocyte found at sites of injury with fibroblast-like properties, within pediatric burn wounds. Seventy 3 mm punch biopsies were taken from 53 burn wounds in 33 children between 7 months and 15 years of age at the time of planned operative debridement and grafting. After fixation and sectioning, immunohistochemistry (IHC) staining was performed for CD34, pro-collagen I, alpha smooth muscle actin, transforming growth factor beta1 and Leucocyte Specific Protein-1 (LSP-1).
