Accuracy of Prehospital Services' Estimated Time to Arrival for Ground Transport to the Emergency Department.
Emergency medical services (EMS) transporting patients to the emergency department (ED) typically call ahead to provide an estimated time to arrival (ETA). Accurate ETA facilitates ED preparation and resource allotment in anticipation of patient arrival. ⋯ Our data demonstrate that prehospital providers underestimate time to ED arrival in most ground transports; however, the median difference between estimated and actual time to arrival is small.

Emergency patients are frequently assigned nonspecific diagnoses. Nonspecific diagnoses describe observations or symptoms and are found in chapters R and Z of the International Classification of Diseases, 10th edition (ICD-10). Patients with such diagnoses have relatively low mortality, but due to patient volume, the absolute number of deaths is substantial. However, information on cause of short-term mortality is limited. ⋯ More than half of ambulance patients released within 24 h from the ED with nonspecific diagnoses, and who subsequently died within 30 days, died unexpectedly. One-fourth died from a pre-existing terminal illness. Patients dying unexpectedly were old, treated with polypharmacy, and often life-threateningly sick at arrival.

Serotonin toxicity is a well-described phenomenon that is commonly attributed to a variety of drug-drug combinations. Some unregulated herbal supplements have been implicated in the onset of serotonin toxicity, however, there is currently minimal literature available on the potential for black cohosh to contribute to rhabdomyolysis and serotonin toxicity, in spite of its known serotonergic properties. ⋯ A middle-aged woman presented to the emergency department with serotonin toxicity and rhabdomyolysis shortly after taking black cohosh supplements in the setting of long-term dual antidepressant use. The serotonin toxicity and rhabdomyolysis resolved with IV fluids, benzodiazepines, and discontinuation of the offending drugs. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Patients are sometimes not aware of how over-the-counter supplements might interact with their prescription medications. Female patients taking black cohosh to manage hot flashes and menopausal symptoms could be at risk for developing rhabdomyolysis and serotonin toxicity if they are also taking other serotonergic agents.

Association Between Frailty and Head Impact Location After Ground-Level Fall in Older Adults.
Mild traumatic brain injuries (TBIs) are highly prevalent in older adults, and ground-level falls are the most frequent mechanism of injury. ⋯ This study found an association between the level of frailty and the head impact location in older patients who sustained a ground-level fall. Our results suggest that head impact location after a fall can help physicians identify frail patients. Although not statistically significant, the prevalence of intracranial hemorrhage seems to increase with the level of frailty.

Timely diagnosis of acute intestinal necrosis (AIN) is lifesaving, but challenging due to unclear clinical presentation. D-lactate has been proposed as an AIN biomarker. ⋯ D-lactate showed low sensitivity for AIN in both average-risk and high-risk patients. Moreover, lipemic interference precluded valid spectrophotometric assessment of D-lactate in half of the patients, further disqualifying the clinical utility of D-lactate as a diagnostic marker for AIN.
