Necrotizing fasciitis is an uncommon and life-threatening soft tissue infection with high mortality. Though early aggressive surgical intervention is important for improving survival, the impact of mortality from different microorganisms remains uncertain. Our study aims to identify the association of mortality and different microorganisms, and the positive and negative predictors of mortality in patients with necrotizing fasciitis. ⋯ Aeromonas infection, Vibrio infection, cancer, hypotension, and band form white blood cell count greater than 10% are independent positive predictors of mortality in patients with necrotizing fasciitis. Streptococcal and staphylococcal infections, in contrast, are not predictors of mortality. The presence of hemorrhagic bullae is an independent negative predictor of mortality. Further study should focus on the accuracy of these factors.

Out-of-hospital clinical experience with noninvasive bilevel positive airway pressure (BiPAP) ventilation is extremely limited compared to inhospital management. The aims of this study were to assess the feasibility of out-of-hospital BiPAP ventilation in patients with acute respiratory distress of various origins, and to look for specific factors associated with failure of this respiratory support. ⋯ The failure rate of BiPAP initiated out-of-hospital was no different from previous reports for inhospital failure rates. Failure was attributable to similar causes.

Case Reports
Painless aortic dissection masquerading as brainstem stroke with catastrophic anticoagulant use.
Painless aortic dissection with only focal neurological symptoms and signs can be a great challenge to the emergency physician. Inadvertently and erroneous treatment of stroke may threaten patient's life. We present a patient with painless aortic dissection (DeBakey I), which was initially misdiagnosed as brainstem stroke with catastrophic anticoagulant use. Finally, the patient died of multiorgan failure after surgical intervention.
