Children with a bacterial musculoskeletal infection (MSKI) require prompt identification and treatment. In Lyme disease endemic areas, children with an MSKI can present similarly to those with Lyme arthritis. Our goal was to derive a clinical prediction rule to accurately identify children at a low risk for an MSKI. ⋯ A novel clinical decision rule that includes PCT, CRP, and a first-tier Lyme EIA was highly sensitive for MSKIs. Although broader external validation is required, the application of this rule may safely reduce invasive testing, procedures, and treatment for low risk children.

Association Between the First-Hour Intravenous Fluid Volume and Mortality in Pediatric Septic Shock.
To determine whether the receipt of more than or equal to 30 mL/kg of intravenous fluid in the first hour after emergency department (ED) arrival is associated with sepsis-attributable mortality among children with hypotensive septic shock. ⋯ Of the 1,982 subjects who had hypotensive septic shock and received a first fluid bolus within 1 hour of arrival at the ED, 1,204 subjects were propensity matched. In the matched patients receiving more than or equal to 30 mL/kg of fluid, 26 (4.3%) of 602 subjects had 30-day sepsis-attributable mortality compared with 25 (4.2%) of 602 receiving less than 30 mL/kg (odds ratio 1.04, 95% confidence interval 0.59 to 1.83). Among the patients with suspected sepsis regardless of blood pressure, 30-day sepsis-attributable mortality was 3.0% in those receiving more than or equal to 30 mL/kg versus 2.0% in those receiving less than 30 ml/kg (odds ratio 1.52, 95% confidence interval 0.95 to 2.44.) CONCLUSION: In children with hypotensive septic shock receiving a timely first fluid bolus within the first hour of ED care, receiving more than or equal to 30 mL/kg of bolus intravenous fluids in the first hour after arrival at the ED was not associated with mortality compared with receiving less than 30 mL/kg.
