Tenecteplase utility in acute ischemic stroke patients: A clinical review of current evidence.
Acute ischemic stroke is a leading cause of disability in the United States. Treatment is aimed at reducing impact of cerebral clot burden and life-long disability. Traditional fibrinolytic treatment with recombinant tissue plasminogen activator (tPA) has shown to be effective but at high risk of major bleeding. Multiple studies have evaluated tenecteplase as an alternative to tPA. ⋯ Recent emerging literature and limited recommendation guidance from governing medical societies leave many emergency medicine providers to weigh benefit versus risk of fibrinolytic therapy and tenecteplase's place in therapy. This review evaluates the available literature regarding tenecteplase and its utility in the treatment of acute ischemic stroke patients.

Pericardial tamponade is neither a clinical nor an echocardiographic diagnosis alone. The echocardiogram carries diagnostic value and should be performed when there is suspicion for tamponade based on the history and physical exam. A pericardial effusion uncovered on point-of-care ultrasound (POCUS) may be mistaken for tamponade and thereby lead to inappropriate and invasive management with pericardiocentesis. ⋯ The emergency physician must recognize and understand the core echocardiographic findings and associated pathophysiology that suggest pericardial tamponade. Together with the history and clinical exam, these findings can help make the overall diagnosis and determine management.

Review Case Reports
Mesenteric venous thrombosis presenting as gastrointestinal bleeding, a challenging diagnosis.
Acute mesenteric venous thrombosis (MVT) is an uncommon cause of intestinal ischemia and is associated with high morbidity and mortality. Patients with acute MVT often present with gastrointestinal (GI) bleeding and other unspecific findings making the diagnosis challenging. This condition requires emergent treatment. ⋯ Physicians should suspect acute MVT in patients with GI bleed while also considering other factors such as, a past medical history of pro-thrombotic conditions, past surgical history of splenectomy, symptoms of nausea, vomiting, abdominal pain, physical exam findings of abdominal tenderness and abdominal distention and a laboratory workup indicating leukocytosis and an increased plasma lactic acid level. An increase in the yield of accurate diagnosis of acute MVT is possible if physicians in the ED accurately interpret all these findings. The authors herein present a case of acute MVT in a patient whose initial complaint was GI bleeding and provide a thorough review of the literature of cases of acute MVT presenting with GI bleed.

Meta Analysis
Interleukin-6 as a diagnostic marker for infection in critically ill patients: A systematic review and meta-analysis.
The ability of blood levels of interleukin (IL)-6 to differentiate between infection and non-infection in critically ill patients with suspected infection is unclear. We assessed the diagnostic accuracy of serum IL-6 levels for the diagnosis of infection in critically ill patients. ⋯ Blood levels of IL-6 have a moderate diagnostic value and a potential clinical utility to differentiate infection in critically ill patients with suspected infection.

Acute liver failure (ALF) remains a high-risk clinical presentation, and many patients require emergency department (ED) management for complications and stabilization. ⋯ ALF remains a rare clinical presentation, but has significant morbidity and mortality. Physicians must rapidly diagnose these patients while evaluating for other diseases and complications. Early consultation with a transplantation center is imperative, as is identifying the underlying etiology and initiating symptomatic care.
