Diagnosed by Reversibility: Unmasking Propofol-Related Infusion Syndrome in a Critically-Ill Elderly Male.

Propofol-related infusion syndrome (PRIS) is an uncommon complication resulting from prolonged propofol use. Common clinical presentations include metabolic acidosis, cardiac arrhythmias, and renal complications. The mortality rate is high if it is not recognized in time.

Stress Test-Induced Left Bundle Branch Block.

Left bundle branch block (LBBB) is an uncommon complication of myocardial perfusion imaging using Regadenoson, a vasodilatory agent. The mechanism is poorly understood at this time but could be related to ongoing ischemia. The use of a Regadenoson with the subsequent occurrence of LBBB could be a predictor of coronary artery disease or conduction abnormalities and should be understood by the physician to diagnose and risk stratify patients undergoing myocardial perfusion imaging properly.

Faraday waves in soft elastic solids.

Recent experiments have observed the emergence of standing waves at the free surface of elastic bodies attached to a rigid oscillating substrate and subjected to critical values of forcing frequency and amplitude. This phenomenon, known as Faraday instability, is now well understood for viscous fluids but surprisingly eluded any theoretical explanation for soft solids. Here, we characterize Faraday waves in soft incompressible slabs using the Floquet theory to study the onset of harmonic and subharmonic resonance eigenmodes.

Effects of efforts to increase response rates on a workplace chronic condition screening survey.

Objective: Expanded health risk appraisal (HRA) surveys can help employers target chronic conditions for outreach or disease management interventions by providing data on the prevalences of conditions and their effects on work performance. However, concerns exist about the accuracy of this data because most HRAs have low response rates. We evaluated these concerns by examining the prevalences and work impairments associated with chronic conditions across four HRA subsamples that differed in intensity of recruitment effort.

The role of trauma debriefing in occupational medicine at an airline.

Most airlines now have formally established Critical Incident Management Programs. The critical incident stress debriefing (CISD) is a tool designed to relieve and prevent event-related stress. The author focuses on the use of CISD to assist victims of smaller traumas, such as assault, bomb threats, and severe turbulence, and shares the results of an American Airlines CIS program for flight attendants.
