The aims of the study were to describe temporal trends in the number, proportion, and per capita use of diabetes-related emergency department (ED) visits and to examine any racial/ethnic disparity in ED use for diabetes-related reasons. ⋯ Despite a marked increase in number and proportion of diabetes-related ED visits during the study period, the per capita use of ED services for diabetes-related visits among the diabetic population remained stable.

The aim of this study was to describe a case of a large traumatic pneumothorax (>55%) that resolved completely without intervention. A pneumothorax is the accumulation of air between the visceral and parietal pleura. It can occur spontaneously or be traumatic. ⋯ She was not treated at another facility during that time. This is a typical manifestation of a traumatic pneumothorax but with an atypical course and outcome. It raises the question of whether, even in the case of traumatic pneumothorax, the threshold for placement of chest tubes could be reconsidered in stable patients.

Ebstein anomaly in an adult presenting with wide QRS tachycardia: diagnostic and therapeutic dilemmas.
A 51-year-old man presented to the emergency department with sustained hemodynamically unstable wide QRS tachycardia and was revived successfully by immediate direct current (DC) cardioversion. There was evidence of previous open heart surgery, possibly atrial septal defect closure. Transthoracic echocardiography showed severe Ebstein anomaly with severe tricuspid regurgitation, no residual atrial septal defect, but with severe right ventricular dysfunction. ⋯ The cause of wide QRS tachycardia in this patient may be WPW related or ventricular tachycardia. This case illustrates the diagnostic and therapeutic dilemmas in patients with wide QRS tachycardia and suspected WPW syndrome. In addition, this case demonstrates that unoperated Ebstein anomaly can present in late adult life with tachyarrhythmias.

The aim of this study was to investigate if the electrocardiographic (ECG) abnormalities assessed early in the emergency department (ED) are associated with the in-hospital mortality of the patients with spontaneous subarachnoid hemorrhage (SAH). ⋯ The occurrence of NSSTTC and prolonged QTc assessed early in the ED are independently associated with the in-hospital mortality in adult patients with spontaneous SAH.

The objective of this study is to investigate the role of sympathovagal balance in predicting inhospital mortality by assessing power spectral analysis of heart rate variability (HRV) among patients with nontraumatic subarachnoid hemorrhage (SAH) in an emergency department (ED). ⋯ Power spectral analysis of the HRV is able to predict inhospital mortality for patients after SAH in an ED. A tilt in the sympathovagal balance toward depressed sympathovagal balance, as indicated by HRV analysis, might contribute to the poor outcome among these patients.
