Format of medical order sheet improves security of antibiotics prescription: The experience of an intensive care unit.

OBJECTIVE: To assess whether formatting the medical order sheet has an effect on the accuracy and security of antibiotics prescription. DESIGN: Prospective assessment of antibiotics prescription over time, before and after the intervention, in comparison with a control ward. SETTING: The medical and surgical intensive care unit (ICU) of a university hospital. PATIENTS: All patients hospitalized in the medical or surgical ICU between February 1 and April 30, 1997, and July 1 and August 31, 2000, for whom antibiotics were prescribed. INTERVENTION: Formatting of the medical order sheet in the surgical ICU in 1998. MEASUREMENTS AND MAIN RESULTS: Compliance with the American Society of Hospital Pharmacists' criteria for prescription safety was measured. The proportion of safe orders increased in both units, but the increase was 4.6 times greater in the surgical ICU (66% vs. 74% in the medical ICU and 48% vs. 74% in the surgical ICU). For unsafe orders, the proportion of ambiguous orders decreased by half in the medical ICU (9% vs. 17%) and nearly disappeared in the surgical ICU (1% vs. 30%). The only missing criterion remaining in the surgical ICU was the drug dose unit, which could not be preformatted. The aim of antibiotics prescription (either prophylactic or therapeutic) was indicated only in 51% of the order sheets. CONCLUSIONS: Formatting of the order sheet markedly increased security of antibiotics prescription. These findings must be confirmed in other settings and with different drug classes. Formatting the medical order sheet decreases the potential for prescribing errors before full computerized prescription is available.

Neutralization of Macrophage Migration Inhibitory Factor (MIF) by Fully Human Antibodies Correlates with Their Specificity for the β-Sheet Structure of MIF.

The macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine that recently emerged as an attractive therapeutic target for a variety of diseases. A diverse panel of fully human anti-MIF antibodies was generated by selection from a phage display library and extensively analyzed in vitro. Epitope mapping studies identified antibodies specific for linear as well as structural epitopes. Experimental animal studies revealed that only those antibodies binding epitopes within amino acids 50-68 or 86-102 of the MIF molecule exerted protective effects in models of sepsis or contact hypersensitivity. Within the MIF protein, these two binding regions form a β-sheet structure that includes the MIF oxidoreductase motif. We therefore conclude that this β-sheet structure is a crucial region for MIF activity and a promising target for anti-MIF antibody therapy.

Evanescent vaso-occlusive choroidal pseudo-tumor with acute painful onset: a presumed vortex vein occlusion.

PURPOSE: The aim of our study was to describe the clinical presentation of an unusual evanescent, exudative, choroidal pseudo-tumor with acute painful onset, and propose a pathogenesis. METHODS: We carried out a retrospective, observational study using the case series of three patients presenting with an evanescent, exudative, choroidal pseudo-tumor with acute painful onset. Ultra-widefield fluorescein and indocyanine green angiography (ICGA) using the Heidelberg Retina Angiograph and the Staurenghi 230 SLO Retina Lens were used to propose a pathogenesis of this unusual entity. RESULTS: In all three cases, acute ocular pain led to discovery of an exudative, partially hemorrhagic choroidal mass (thickness 2.4 mm-4.1 mm on ultrasound) that quickly regressed within weeks. In the subacute phase, all patients showed choroidal circulation abnormalities on dynamic wide-field ICGA in the affected quadrant, with delayed arterio-venous filling in two patients, and a poorly-defined vortex vein in the third. The choroidal circulation abnormalities resolved within 8-12 weeks, simultaneously with the spontaneous resolution of the choroidal pseudo-tumor. The findings evoked a self-resolving vortex vein occlusion in the corresponding quadrants with acute, painful choroidal exudation. CONCLUSIONS: An evanescent, exudative, hemorragic choroidal pseudo-tumor with acute painful onset may be caused by a vortex vein occlusion. Future patients need to be studied with ICGA in the acute phase to confirm this hypothesis.
