BACKGROUND Peripheral intravenous catheter (PIV) insertion is a common, painful experience for many children in the pediatric emergency department. Although local anesthetics such as injected buffered lidocaine have been shown to be effective at reducing pain and anxiety associated with PIV insertion, they are not routinely used. ELA-Max, a topical local anesthetic, has the advantage of needle-...

Filamentous phage f1 encodes protein IV (pIV), a protein essential for phage morphogenesis that localizes to the outer membrane of Escherichia coli, where it is found as a multimer of 10 to 12 subunits. Introduction of internal His or Strep affinity tags at different sites in pIV interfered with its function to a variable extent. A spontaneous second-site suppressor mutation in gene IV allowed ...

PURPOSE To assess the proximal humerus intraosseous (PHIO) catheter placement as a preferred method for venous access over conventional methods, including peripheral intravenous (PIV) and central venous catheters (CVCs), during emergency room resuscitation. METHODS In phase 1, conventional methods for venous access (PIV and CVC) were assessed for all patients presenting to the emergency depar...

The reaction of LnCl3·6H2O (Ln = Dy(3+), Tb(3+) and Ho(3+)) with the multisite coordinating ligand N'-(2-hydroxy-3-(hydroxymethyl)-5-methylbenzylidene)acetohydrazide (LH3) in the presence of pivalic acid (PivH) leads to the formation of three isostructural homometallic pentanuclear complexes, [Dy5(LH)4(η(1)-Piv)(η(2)-Piv)3(μ2-η(2)η(1)Piv)2(H2O)]·Cl·9·5H2O·5MeOH (1), [Tb5(LH)4(η(1)-Piv)(η(2)-Piv...

We designed a prospective study to describe the clinical impact of the parainfluenza viruse (PIV) types detected in hospitalized children with respiratory tract infections from September 2008 to August 2010 in Spain. PIV infections were a significant proportion of viral respiratory detections (11.8% of cases). PIV types 3 and 4 were most commonly detected. There were clinical differences betwee...

OBJECTIVES Peripheral intravenous catheter (PIV) placement is a common, painful, and frequently difficult procedure in children. The VeinViewer is a device that delineates subcutaneous veins using near-infrared light and video technology. To the best of our knowledge, the benefit of this device for PIV placement in children in the emergency department (ED) has not been studied. METHODS The au...
