Ovarian and tubal torsion: imaging findings on US, CT, and MRI.

Accurate diagnosis of adnexal torsion is often challenging, as clinical presentation is nonspecific and the differential for pelvic pain is broad. However, prompt diagnosis and treatment is critical to good clinical outcomes and preservation of the ovary and/or fallopian tube. Ultrasound (US) imaging is most frequently used to assess torsion.

Comparison of sudden cardiac arrest resuscitation performance data obtained from in-hospital incident chart review and in situ high-fidelity medical simulation.

Introduction: High-fidelity medical simulation of sudden cardiac arrest (SCA) presents an opportunity for systematic probing of in-hospital resuscitation systems. Investigators developed and implemented the SimCode program to evaluate simulation's ability to generate meaningful data for system safety analysis and determine concordance of observed results with institutional quality data.

Methods: Resuscitation response performance data were collected during in situ SCA simulations on hospital medical floors.

High-fidelity medical simulation as an assessment tool for radiology residents' acute contrast reaction management skills.

Purpose: The aims of this study were to use medical simulation as an assessment tool for the evaluation of radiology residents' compliance with contrast reaction treatment protocols and to gauge their perceptions of the simulation experience.

Methods: A prospective, observational study of postgraduate year 2 and 3 radiology residents' management of simulated life-threatening contrast reactions was designed. After standard didactic teaching on departmental contrast reaction protocols, residents participated individually in high-fidelity medical simulations of acute contrast reactions.

Does 16-detector computed tomography improve detection of non-traumatic subarachnoid hemorrhage in the Emergency Department?

The diagnosis of subarachnoid hemorrhage remains difficult to establish, yet the sensitivity of increasingly available 16-detector computed tomography (CT) has not been evaluated. The objective of this study was to estimate the sensitivity of 16-detector CT for the diagnosis of non-traumatic subarachnoid hemorrhage in the Emergency Department (ED). A retrospective review was performed in an academic tertiary care hospital.

Myocardial preconditioning factors evoke mesenteric ischemic tolerance via opioid receptors and K(ATP) channels.

We have shown that a reverse-phase concentrate generated from the effluent of preconditioned (PC) rabbit hearts evokes a cardioprotective effect in virgin acceptor hearts. With the use of a model of sustained (1 h) simulated ischemia in isolated, spontaneously contracting rabbit jejunum, our current aims were to 1) determine whether protective factor(s) released from PC hearts can improve ischemic tolerance in noncardiac tissue; and 2) obtain preliminary insight into the mediator(s) involved in triggering and eliciting this remote protection. Recovery of contractile force following reoxygenation (our index of ischemic tolerance) was enhanced in jejunal segments pretreated with concentrate generated from PC hearts (33 +/- 3% of baseline, P < 0.

Delta opiates increase ischemic tolerance in isolated rabbit jejunum.

Unlabelled: Mammalian hibernation is mediated by humoral agonists of the delta opioid receptor (DOR). Moreover, transfer of either humoral or synthetic DOR agonists to non-hibernators reportedly induces a state of improved myocardial ischemic tolerance.

Objective: To determine whether the DOR agonist D-Ala 2, D-Leu 5, enkephalin (DADLE) similarly elicits protection in noncardiac-i.
