Although a decline in overall fatal drowning deaths among children has been noted, national trends and disparities in pediatric drowning hospitalizations have not been reported.\n\nMETHODS: To describe trends in pediatric
drowning in the United States and provide national benchmarks for state and regional comparisons, we analyzed existing data (1993-2008) from the Nationwide Inpatient Sample, the largest, longitudinal, all-payer inpatient care database in the United States. Children aged 0 to 19 years were included. Annual rates of drowning-related hospitalizations were determined, stratified by age, gender, and outcome.\n\nRESULTS: From 1993 to 2008, selleck chemical the estimated annual incidence rate of pediatric hospitalizations associated with drowning declined 49% from 4.7 to 2.4 per 100 000 (P < .001). The rates declined for all age groups and for STAT inhibitor both males and females. The hospitalization rate for males remained consistently greater than for females at each point in time. Rates of fatal drowning hospitalization declined from 0.5 (95% confidence interval,
0.4-0.7) deaths per 100 000 in 1993-1994 to 0.3 (95% confidence interval, 0.2-0.4) in 2007-2008 (P < .01). No difference was observed in the mean hospital length of stay over time.\n\nCONCLUSIONS: Pediatric hospitalization rates for drowning have decreased over the past 16 years. Our study provides national estimates of pediatric drowning hospitalization that can be used as benchmarks to target and assess prevention strategies. Pediatrics 2012;129:275-281″
“Background: The suture bridge (SB) transosseous-equivalent rotator cuff repair reduces re-tear rates compared with single-row or other double-row constructs. However, failure rates continue to be high, especially in large and massive tears. The aim of this study was to assess the biomechanical performance of a new SB repair with use of a medial grasping suture compared with RSL3 nmr the traditional SB repair. Methods: Seven
matched pairs of sheep infraspinatus tendons were randomly assigned to either SB or suture bridge with grasping suture (SBGS) repair. Each construct was subjected to cyclic loading and then loaded until failure under displacement control in a materials testing machine. Footprint displacement, ultimate load to failure, and mode of failure were assessed. Results: The rotator cuff footprint displacement was less during tensile loading with the addition of the medial grasping suture. The ultimate load to failure was significantly greater for the SBGS repair group than for the SB repair group (334.0 N vs 79.8 N). The mode of failure was the tendon pulling off the footprint in all cases (type 1 tear). There were no failures in which the tendon tore at the medial row of anchors, leaving part of the tendon still on the footprint (type 2 tear).
