TBI surveillance using the common data elements for traumatic brain injury: a population study.

Background: To characterize the patterns of presentation of adults with head injury to the Emergency Department.

Methods: This is a cohort study that sought to collect injury and outcome variables with the goal of characterizing the very early natural history of traumatic brain injury in adults. This IRB-approved project was conducted in collaboration with our Institution's Center for Translational Science Institute.

Aortic dissection and thrombosis diagnosed by emergency ultrasound in a patient with leg pain and paralysis.

The authors present a case of aortic dissection and abdominal aortic aneurysm thrombosis in a 78-year-old male who presented to the emergency department (ED) complaining of lower extremity and paralysis for the past 1.5 hours. The initial vital signs in the ED were as follows: blood pressure (BP) 132/88 mmHg, heart rate (HR) 96, respiratory rate (RR) 14, and an oxygen saturation of 94% at room air.

Trimethoprim-sulfamethoxazole-induced hyperkalemia in a patient with normal renal function.

The authors present a case of Trimethoprim-sulfamethoxazole-induced hyperkalemia in a patient with normal renal function. While toxicity of this drug has been reported in patients with renal insufficiency, this case highlights the toxicity associated with normal kidney function. Due to its popularity in the medical field and to the largely unrecognized effect of hyperkalemia, it is important to consider such adverse effects when prescribing TMX-SMX.

Role of bedside ultrasound in CMV retinitis: a case report.

We present a case of retinal detachment diagnosed by emergency department bedside ultrasonography in a patient with CMV retinitis. The indications and findings of ocular ultrasonography are discussed.

The Triglyceride Paradox in Stroke Survivors: A Prospective Study.

Objective. The purpose of our study was to understand the association between serum triglycerides and outcomes in acute ischemic stroke (AIS) patients. Methods.

Fibroelastoma as a culprit of syncope.

We present a case of a valvular mass diagnosed by emergency department bedside ultrasonography in a young patient with syncope. Bedside ultrasound has become a valuable tool in the evaluation of patients with syncope in the emergency department. This patient was believed to have a fibroelastoma on ultrasound that was confirmed by magnetic resonance and ultimately by postsurgical pathological evaluation.

Posterior reversible encephalopathy syndrome (PRES) and CT perfusion changes.

Posterior reversible encephalopathy syndrome (PRES) can present with focal neurologic deficits, mimicking a stroke and can often represent a diagnostic challenge when presenting atypically. A high degree of suspicion is required in the clinical setting in order to yield the diagnosis. Cerebral CT perfusion (CTP) is utilized in many institutions as the first line in acute stroke imaging.

The impact of blood pressure hemodynamics in acute ischemic stroke: a prospective cohort study.

Objective: To assess relationships between blood pressure hemodynamic measures and outcomes after acute ischemic stroke, including stroke severity, disability and death.

Methods: The study cohort consisted of 189 patients who presented to our emergency department with ischemic stroke of less than 24 hours onset who had hemodynamic parameters recorded and available for review. Blood pressure (BP) was non-invasively measured at 5 minute intervals for the length of the patient's emergency department stay.

Cardioembolic but not other stroke subtypes predict mortality independent of stroke severity at presentation.

Introduction. Etiology of acute ischemic stroke (AIS) is known to significantly influence management, prognosis, and risk of recurrence. Objective.

Abdominal trauma: never underestimate it.

Introduction. We present a case of a sports injury. The initial presentation and clinical examination belied serious intra-abdominal injuries.

Altered mental status and a not-so-benign rash.

Introduction. The authors are presenting a case of Thrombotic Thrombocytopenic Purpura (TTP) that presented with complaints of altered mental status and found to have petechiae. Case Presentation.

Seizures in pregnancy/eclampsia.

The physical and emotional stress of pregnancy can precipitate new-onset seizures in a woman. In these cases, emergency department evaluations must rule out underlying pathology. Careful consideration of antiepileptic drug use must be considered in the first trimester as all antiepileptic drugs have been linked to some teratogenic effect.
