The objective of this study was to describe the characteristics of patients presenting to the emergency department with cardiac symptoms subsequently diagnosed to have systemic lupus erythematosus (SLE). ⋯ Patients presenting to the emergency department with cardiac symptoms without a history of cardiopulmonary disease or traditional cardiovascular disease risk factors should be assessed for an underlying cause of cardiac decompensation. If the patients exhibit extracardiac manifestations or their illnesses involve multiple-organ systems, screening tests for autoimmune diseases such as SLE are mandatory.

Law enforcement restraint-related death is frequently associated with excited delirium syndrome (ExDS). Because such deaths are rare, the pathophysiology underlying ExDS deaths remains unknown, making identification of high-risk situations challenging. This study describes the medical conditions and situations surrounding restraint of individuals identified by law enforcement to be experiencing ExDS. ⋯ Officer-identified cases of ExDS infrequently involved individuals requiring extensive restraint or with medical conditions that objectively placed them at high risk for sudden death. The low specificity of this syndrome in predicting risk of sudden death may present a challenge to law enforcement and emergency physicians.

Emergency department (ED) visits increase during the influenza seasons. It is essential to identify statistically significant correlates in order to develop an accurate forecasting model for ED visits. Forecasting influenza-like-illness (ILI)-related ED visits can significantly help in developing robust resource management strategies at the EDs. ⋯ Google Flu Trends data statistically improve the performance of predicting ILI-related ED visits in Douglas County, and this result can be generalized to other communities. Timely and accurate estimates of ED volume during the influenza season, as well as during pandemic outbreaks, can help hospitals plan their ED resources accordingly and lower their costs by optimizing supplies and staffing and can improve service quality by decreasing ED wait times and overcrowding.

Multiple shocks of the implantable cardioverter/defibrillator (ICD) can cause myocardial injury, contributing to the progression of underlying heart disease. The aim was to evaluate if the elevation of troponin I after multiple ICD shocks has impact on the prognostic of these patients. ⋯ A large proportion of patients with multiple ICD shocks have troponin I elevation, and these patients have a higher risk of death or hospitalization due to heart failure.
