Tracheal intubation is necessary in the setting of pediatric/neonatal critical care transport but information regarding usefulness and efficiency of a confirmatory postintubation chest radiograph is limited. We hypothesize that routine postintubation chest radiograph to confirm tracheal tube position is not informative and can be eliminated to improve efficiency without compromising safety in transport. This was a prospective observational study. The primary study outcome was the rate of tracheal tube repositioning after postintubation chest radiograph and the secondary outcome was the on-scene time. Additional data obtained included the initial accuracy of tracheal tube depth based on Pediatric Advanced Life Support and Neonatal Resuscitation Program guidelines. A children's hospital-based pediatric/neonatal critical care transport team in northeastern Ohio. All pediatric/neonatal patients intubated by the transport team during the 18-month study period (January 2009-July 2010). There were 77 patients enrolled (43 pediatric, 34 neonatal). A postintubation chest radiograph was obtained 85.7% of the time and showed tracheal tube malposition in 47% of cases. No difference was seen in the rate of malpositioned tracheal tubes in the neonatal group compared with pediatric group (51.7% vs. 43.2%, p = 0.54). The calculated tracheal tube depth based on the Neonatal Resuscitation Program and Pediatric Advanced Life Support guidelines was correct in 50% of the neonates and 41.9% of the pediatric patients. In patients with appropriate initial tracheal tube depth by calculations, the tracheal tube was repositioned at similar rates after postintubation chest radiograph in both neonatal and pediatric patients (50% vs. 41.9%, p = 0.48). When comparing mean onscene times for patients with/without a postintubation chest radiograph, the neonatal patients saved 33 minutes on average when no chest radiograph was obtained (mean ± sd: 60.6 ± 35.8 min vs. 93.8 ± 23.8 min, p = 0.01). There was no statistical difference in on-scene time for pediatric patients whether they did or did not receive a postintubation chest radiograph. Although postintubation chest radiographs may extend the overall on-scene transport times in select patients, our data show that the postintubation chest radiographs remain informative in pediatric/neonatal critical care specialty transport and should be obtained when feasible.

We performed a genome-wide association study (GWAS) of Kawasaki disease in Japanese subjects using data from 428 individuals with Kawasaki disease (cases) and 3,379 controls genotyped at 473,803 SNPs. We validated the association results in two independent replication panels totaling 754 cases and 947 controls. We observed significant associations in the FAM167A-BLK region at 8p22-23 (rs2254546, P = 8.2 × 10 -21), in the human leukocyte antigen (HLA) region at 6p21.3 (rs2857151, P = 4.6 × 10 -11) and in the CD40 region at 20q13 (rs4813003, P = 4.8 × 10 -8). We also replicated the association of a functional SNP of FCGR2A (rs1801274, P = 1.6 × 10 -6) identified in a recently reported GWAS of Kawasaki disease. Our findings provide new insights into the pathogenesis and pathophysiology of Kawasaki disease. © 2012 Nature America, Inc. All rights reserved.

Kawasaki disease is a systemic vasculitis of unknown etiology, with clinical observations suggesting a substantial genetic contribution to disease susceptibility. We conducted a genome-wide association study and replication analysis in 2,173 individuals with Kawasaki disease and 9,383 controls from five independent sample collections. Two loci exceeded the formal threshold for genome-wide significance. The first locus is a functional polymorphism in the IgG receptor gene FCGR2A (encoding an H131R substitution) (rs1801274; P = 7.35 × 10 -11, odds ratio (OR) = 1.32), with the A allele (coding for histadine) conferring elevated disease risk. The second locus is at 19q13, (P = 2.51 × 10 -9, OR = 1.42 for the rs2233152 SNP near MIA and RAB4B; P = 1.68 × 10 -12, OR = 1.52 for rs28493229 in ITPKC), which confirms previous findings. The involvement of the FCGR2A locus may have implications for understanding immune activation in Kawasaki disease pathogenesis and the mechanism of response to intravenous immunoglobulin, the only proven therapy for this disease. © 2011 Nature America, Inc.
