Randomized Controlled Trial
Intranasal Topical Application of Tranexamic Acid in Atraumatic Anterior Epistaxis: A Double-Blind Randomized Clinical Trial.
To determine the effectiveness of intranasal topical application of tranexamic acid in reducing the need for anterior nasal packing and determine the number of episodes of rebleeding in adult patients presenting with spontaneous atraumatic anterior epistaxis. ⋯ Intranasal topical application of tranexamic acid is associated with a lower rate of need for anterior nasal packing and a shortened stay in the ED; it may be considered a part of the treatment for atraumatic anterior epistaxis.

The synthetic cathinone 3-methylmethcathinone (3-MMC, or metaphedrone) has recently gained popularity. We studied the numbers of 3-MMC poisonings over time and the clinical effects following poisonings with 3-MMC. ⋯ The number of 3-MMC poisonings reported to the DPIC has increased over time. Most poisonings with 3-MMC resulted in moderate toxicity and involved sympathomimetic effects, while severe effects were observed in 5 cases.

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.
