Mercury poisoning is an uncommon diagnosis in the United States, but it is a differential diagnosis that physicians should consider because it can lead to potentially fatal complications if untreated. Due to the nonspecific presentation of mercury poisoning, which includes symptoms such as fever, nausea, vomiting, and abdominal pain, misdiagnosis may occur unless a proper history is taken. ⋯ In the present case, a white female patient was misdiagnosed repeatedly with a viral illness and sent home from the local hospital. The patient presented with a diffuse full-body rash, fever, myalgias, headache, peripheral neuropathy, oral paresthesias, and tender cervical posterior lymphadenopathy. After obtaining a thorough history, it was discovered that the patient and her family were exposed to mercury through a spill of elemental mercury in their home. Blood mercury levels in the patient were 170 ng/mL. The patient was treated with a course of dimercaprol. Her symptoms improved and she was discharged on hospital day 5. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Ultimately, mercury poisoning is a treatable condition, but if exposure continues and the patient is not treated, it may lead to complications such as severe pneumonitis, renal tubular necrosis, and neurological dysfunction. In some instances, neurological symptoms may persist even if the source of exposure is removed. For these reasons, recognition and prompt treatment after a suspected exposure is important.

Randomized Controlled Trial
Intranasal Sufentanil Versus Intravenous Morphine for Acute Pain in the Emergency Department: A Randomized Pilot Trial.
Patients in the United States frequently seek medical attention in the emergency department (ED) to address their pain. The intranasal (i.n.) route provides a safe, effective, and painless alternative method of drug administration. Sufentanil is an inexpensive synthetic opioid with a high therapeutic index and rapid onset of action, making it an attractive agent for management of acute pain in the ED. ⋯ The use of i.n. sufentanil at 0.7 μg/kg/dose resulted in rapid and safe analgesia with comparable efficacy to i.v. morphine for up to 30 min in patients who presented with acute pain in the ED.

Case Reports
Cerebral Venous Thrombosis: An Uncommon Cause of Papilledema on Bedside Ocular Ultrasound.
Cerebral venous thrombosis (CVT) is a rare, difficult-to-diagnose form of venous thromboembolic disease and is considered a type of stroke. Its presentation is highly variable and may be easily confused for more common and less debilitating or life-threatening diagnoses such as migraine, seizure, or idiopathic intracranial hypertension. ⋯ A 25-year-old woman presented with a complaint of bifrontal throbbing headache and blurry vision. A bedside ultrasound of the orbit suggested increased intracranial pressure. A subsequent computed tomography venogram demonstrated a left transverse sinus thrombosis. The patient was started on enoxaparin and admitted for bridging to warfarin and evaluation for hypercoagulable state. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: CVT is a rare form of stroke that carries a high rate of mortality and morbidity and masquerades as more common and benign diagnoses. Emergency department bedside ultrasound of the orbit may make the diagnosis of CVT more attainable by identifying patients with increased intracranial pressure.

Bodybuilding is a demanding sport, which requires high-volume, high-resistance weight training and augmented nutritional intake, toward an increase of overall body muscle mass accompanied by an overall decrease of body fat percentage and mass. Among bodybuilders, the use of various legal and illegal supplements is common. These supplements may be naturally occurring or man-made. ⋯ We discuss the case of a 30-year-old male bodybuilder presenting with coma due to severe hypoglycemia from unknown cause, necessitating iterative glucose infusions, which was subsequently found to be related to cryptic insulin injections. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In strength athletes, especially amateurs, the recourse to performance-enhancement drugs (e.g., insulin) is frequent. Beyond the specificity of care required for surreptitious insulin intoxication, emergency physicians should be alert to the possibility that exogenous insulin has been injected for use as an ergogenic aid by bodybuilders and others seeking to increase their body muscle mass when they encounter a patient with a decreased level of consciousness and treatment-refractory hypoglycemia. Moreover, in case of suspicion of such intoxication, the use of other illegal supplements should be screened, due to potentially associated risks of complication.

Freestanding emergency departments (FSEDs), EDs not attached to acute care hospitals, are expanding. One key question is whether FSEDs are more similar to higher-cost hospital-based EDs or to lower-cost urgent care centers (UCCs). ⋯ After three UCCs converted to FSEDs, patient volume decreased and reimbursement per visit increased, despite no change in patient characteristics and little change in conditions managed. These case studies suggest that some FSEDs are similar to UCCs in patient mix and conditions treated.
