QTc dispersion in the electrocardiogram (ECG) is a new important prognostic factor for many diseases, but its role in intracerebral hemorrhage (ICH) is not clear. This study was performed to investigate the prognostic significance of QTc dispersion in the acute ICH patients. We studied the differences of QTc dispersion from the initial ECG in the ED between the survival to discharge and nonsurvival patients retrospectively. ⋯ The QTc dispersion and GCS were the statistically significant independent predictors in the multiple logistic analyses. Increased QTc dispersion in the initial ED electrocardiograph is an important prognostic factor for ICH patients. More attention to the disposition and intensive care should be given for these patients.

The objectives of this study were to review variable factors influencing outcomes in hanging and to identify prognostic factors related to outcomes. Forty-seven patients presented to our department. Eleven patients survived and 36 died. ⋯ In survivors, eight patients had a GCS greater than 3. A significant difference in outcome existed between patients with a GCS of 3 and those with a GCS greater than 3. Hanging time, presence of CPA at the scene and on arrival, and GCS on arrival represented prognostic factors of outcome in hanging.

Correctly identifying and appropriately triaging patients who present to the ED with the broad range of symptoms suggestive of acute cardiac ischemia (ACI: unstable angina pectoris [UAP] and acute myocardial infarction [AMI]) remains one of the greatest challenges in EM. Although a number of diagnostic technologies have been described to aid in this triage process, each of these tests or technologies has limitations. We report a case series in which either the use of adjuncts with unknown performance or tests with known but not considered limitations could have contributed to the failure to appropriately triage and treat patients with ACI. ⋯ The limitations of a negative exercise electrocardiographic stress test (ETT) are illustrated in the second case. Finally, the limitations of a negative coronary angiogram, the "gold standard" test for symptomatic coronary artery disease, are discussed. We review the literature on technologies to aid in the evaluation of patients who present to the ED with symptoms suggestive of ACI.

Hepatic portal venous gas (HPVG) is a rare radiographic finding of significance. Most cases with HPVG are related to mesenteric ischemia that have been associated with extended bowel necrosis and fatal outcome. With the help of computed tomography (CT) in early diagnosis of HPVG, the clinical outcome of patients with mesenteric ischemia has improved. ⋯ Patients with radiographic diagnosis of HPVG should receive a detailed history review and physical examination. The patient's underlying condition should be determined to provide a solid ground for exploratory laparotomy. A flow chart is presented for facilitating the management of patients with HPVG in the ED.
