We report a case of fatal necrotizing soft tissue infection (NSTI) due to Clostridium perfringens (CP) in a neutropenic patient with diabetes mellitus. As in many cases, by the time a diagnosis was made, the condition had rapidly progressed to its late stages, resulting in a fatal outcome. The emergency physician should be aware of NSTI as a complication when patients present with pain out of proportion to physical findings and/or signs of soft tissue compromise. Negative prognostic factors for survival are diabetes mellitus, immunosuppression, age, and toxic shock syndrome...

OBJECTIVES: Physical examination can identify palpable splenomegaly easily, but evaluating lesser degrees of splenomegaly is problematic. Hand-carried ultrasound allows rapid bedside assessment of patients. We conducted this study to determine whether hand-carried ultrasound can reliably assess spleen size. METHODS: Patients with varying degrees of splenomegaly were studied. Two sonographers blindly measured spleen size in each patient using either a hand-carried or conventional ultrasound device in random order...

BACKGROUND: Lung ultrasound has been shown to identify in real-time, various pathologies of the lung such as pneumonia, viral pneumonia, and acute respiratory distress syndrome (ARDS). Lung ultrasound maybe a first-line alternative to chest X-ray and CT scan in critically ill patients with respiratory failure. We describe the use of lung ultrasound imaging and findings in two cases of severe respiratory failure from avian influenza A (H7N9) infection. METHODS: Serial lung ultrasound images and video from two cases of H7N9 respiratory failure requiring mechanical ventilation and extracorporeal membrane oxygenation in a tertiary care intensive care unit were analyzed for characteristic lung ultrasound findings described previously for respiratory failure and infection...

BACKGROUND: Necrotizing fasciitis (NF) is a rare but deadly disease. Diagnosis of necrotizing soft tissue infections can be challenging for a variety of reasons. Point-of-care (POC) ultrasound (US) has been described as a diagnostic tool to help the acute care clinician make the early diagnosis that is imperative to optimize outcomes. OBJECTIVE: To report a case of Group A Streptococcus NF recognized with POC US, and subsequent negative findings on computed tomography (CT) and magnetic resonance imaging (MRI)...

The early diagnosis of necrotizing fasciitis is often ambiguous. Computed tomography and magnetic resonance imaging, while sensitive and specific modalities, are often time consuming or unavailable. We present a case of necrotizing fasciitis that was rapidly diagnosed using bedside ultrasound evaluating for subcutaneous thickening, air, and fascial fluid (STAFF). We propose the STAFF ultrasound exam may be beneficial in the rapid evaluation of unstable patients with consideration of necrotizing fasciitis, in a similar fashion to the current use of a focused assessment with sonography for trauma exam in the setting of trauma...

Currently, infectious mononucleosis (IM) is a clinically diagnosed condition. According to the American Family Physician criteria for IM, splenomegaly is the key factor that distinguishes IM from other causes of sore throat. Though heterophile antibody tests are often ordered to confirm diagnosis of IM, this test has a high false-negative rate early in the course of the disease. This case report provides an example of how the use of ultrasound to diagnose splenomegaly and subsequently mononucleosis increases diagnostic accuracy...
