For nearly 51 million persons in the United States who lack health care insurance, the emergency department (ED) functions as a safety net where no patient is denied care based on ability to pay, and much public rhetoric has characterized ED utilization by uninsured patients. We estimated national ED utilization by uninsured patients and compared uninsured and insured ED patients in terms of demographics, diagnostic testing, disposition and final diagnoses. ⋯ Uninsured patients account for approximately 20 million or 1 in 6 ED visits annually in the United States and have differences in demographics, diagnoses, and ED utilization patterns from those with insurance.

Case Reports
Early onset of cooling catheter-related right atrial thrombus following cardiac arrest.
Catheter-related right atrial thrombus (RAT) is an uncommon life-threatening complication. Few cases of endovascular cooling catheter–related complications have been reported. We report the first case of endovascular cooling catheter–related RAT. ⋯ Anticoagulation with enoxaparin for 2 weeks completely resolved the RAT, and he was consequently treated with radiofrequency ablation and received an implanted cardiac defibrillator. This case report highlights the occurrence of endovascular cooling catheter–related RAT early after the placement of a catheter. Physicians should monitor whether RAT occurs during and following therapeutic hypothermia with a cooling catheter.

Case Reports
Severe blood loss anemia in a Jehovah's Witness treated with adjunctive hyperbaric oxygen therapy.
We describe the case of a 39-year-old African-American woman who developed sudden onset, near-term placental abruption with severe blood loss anemia whose religious beliefs precluded her from receiving any blood products. The patient had lost most of her blood volume, with a reported hemoglobin level of 1.9 g/dL, developed multisystem failure, and disseminated intravascular coagulation with bilateral deep venous thrombosis. Adjunctive hyperbaric oxygenation (HBO) therapy was considered, and the patient was referred for treatment. ⋯ She was discharged to a rehabilitation facility on hospital day 29 and then to home, soon thereafter. The patient had no evidence of sustained physical or cognitive impairment at time of discharge, and there were no reported complications associated with HBO therapy. Adjunctive HBO therapy should be considered in the management of patients with exceptional severe blood loss anemia who refuse the use of blood products.

Transient ischemic attack or ischemic stroke in hereditary hemorrhagic telangiectasia (HHT), a rare genetic disease, is frequent in clinical practice and often associated to pulmonary arteriovenous malformations (PAVMs), potentially determining paradoxical cerebral embolism. We describe the case of a 53-year-old woman with a previous history of recurrent epistaxis, admitted to our unit for a transient episode of diplopia and unbalance. ⋯ Secondary cerebrovascular prevention with antithrombotic therapy was early stopped for the worsening of epistaxis. Neurologic symptoms are common in HHT, and saline contrast transcranial Doppler can be a reliable alternative to echocardiography for detection of right to left shunt commonly related to underlying PAVMs.

Plasmodium vivax malaria is typically characterized by a mild and benign clinical course. Organ dysfunction is rarely seen, whereas acute lung injury has been found to occur after starting antimalarial treatment. We present an unusual case of severe sepsis and septic shock due to Plasmodium vivax monoinfection.
