Community-acquired methicillin-resistant Staphylococcus aureus (MRSA) is the most common cause of purulent skin and soft-tissue infections (SSTIs) in the Unites States. Little is known regarding health care provider management strategies for abscesses in the emergency department (ED). Understanding variability in practice patterns could be an important step in implementing evidence-based guidelines. ⋯ Practice patterns vary significantly, especially antibiotic overuse, at least in this urban academic ED. Further study should be undertaken to evaluate factors that influence management strategies for SSTI.

This study was designed to determine whether the mainstream end-tidal carbon dioxide (ETCO2) measurement can accurately predict the partial arterial carbon dioxide (Paco2) level of patients presented to emergency department (ED) with acute dyspnea. ⋯ Mainstream ETCO2 measurement accurately predicts the arterial Paco2 of patients presented to ED with acute dyspnea. Further studies comparing mainstream and sidestream methods in these patients are required.

The aim of this study was to evaluate the diagnostic efficacy of multiple tests-heart-type fatty acid-binding protein (H-FABP), cardiac troponin I (cTnI), creatine kinase-MB, and myoglobin-for the early detection of acute myocardial infarction among patients who present to the emergency department with chest pain. ⋯ Testing both H-FABP and cTnI using the Cardiac Array proved to be both a reliable diagnostic tool for the early diagnosis of myocardial infarction/acute coronary syndrome and also a valuable rule-out test for patients presenting at 3 to 6 hours after chest pain onset.

Comparative Study
A comparison of different diagnostic tests in the bedside evaluation of pleuritic pain in the ED.
Bedside lung ultrasound (LUS) is useful in detecting radio-occult pleural-pulmonary lesions. The aim of our study is to compare the value of LUS with other conventional routine diagnostic tools in the emergency department (ED) evaluation of patients with pleuritic pain and silent chest radiography (CXR). ⋯ Chest radiography and blood tests may be inadequate in the diagnostic process of pleuritic pain. In case of silent CXR, LUS is critical for identifying patients with pleural-pulmonary radio-occult conditions at bedside and cannot be safely replaced by other conventional methods.
