Self-Collection for Primary HPV Testing: Acceptability in a Large Urban Emergency Department.

Study Objective: Overdue cervical cancer screening increases the risk of invasive cervical cancer. It is important to identify settings where self-collection for primary human papillomavirus (HPV) testing can be implemented to have high effect on cervical cancer screening among hard-to-reach women with overdue screening. Herein, we examined the acceptability of HPV self-collection, including completion rates, attitudes, and experiences among women seeking noncritical care at a high-volume urban safety-net hospital emergency department (ED) in Houston, Texas, United States.

Hyperkalemia and Electrocardiogram Manifestations in End-Stage Renal Disease.

Hyperkalemia is one of the more common acute life-threatening metabolic emergencies. The aim of our study is to determine the correlation and accuracy of abnormal ECG parameters as a function of serum potassium concentration in the end-stage renal disease (ESRD) population. We performed a retrospective chart review of emergency department patients presenting with ESRD and receiving emergent hemodialysis treatment.

Diagnosing and managing acute heart failure in the emergency department.

Heart failure is a clinical syndrome that results from the impairment of ventricular filling or ejection of blood and affects millions of people worldwide. Diagnosis may not be straightforward and at times may be difficult in an undifferentiated patient. However, rapid evaluation and diagnosis is important for the optimal management of acute heart failure.

Special Considerations in Trauma Patients.

The emergent management of a traumatic injury can be an extremely intense situation. These assessments can be even more difficult when patients have an underlying psychiatric condition. After a protocoled evaluation of the traumatic injuries, the psychological manifestation of diseases can be addressed.

Asymmetric Weakness and West Nile Virus Infection.

Background: Weakness is a common presentation in the emergency department (ED). Asymmetric weakness or weakness that appears not to follow an anatomical pattern is a less common occurrence. Acute flaccid paralysis with no signs of meningoencephalitis is one of the more uncommon presentations of West Nile virus (WNV).

Elevated lipase without pancreatitis in infectious colitis.

Background: An elevated lipase typically confirms the diagnosis of pancreatitis. Elevated lipase may be associated with other disorders, typically with some influence on the pancreas. The differential is more limited than elevated amylase secondary to the mostly unique production of lipase in pancreatic acinar cells.

Disorders of sodium and water balance.

Dysnatremias occur simultaneously with disorders in water balance. The first priority is to correct dehydration; once the patient is euvolemic, the sodium level can be reassessed. In unstable patients with hyponatremia, the clinician should rapidly administer hypertonic saline.

Emergency physician ability to predict methicillin-resistant Staphylococcus aureus skin and soft tissue infections.

Methicillin-resistant Staphylococcus aureus (MRSA) has a high prevalence in Emergency Departments (EDs). The objective of this study was to determine the ability of emergency physicians to predict MRSA infection in purulent wounds. A prospective observational study was conducted in an urban, tertiary academic center in ED patients presenting with purulent wounds and abscesses that received wound culture.

Brain natriuretic peptide (BNP) testing in the emergency department.

In the past decade a large amount of attention has been focused on brain natriuretic peptide (BNP) testing in the evaluation of patients with acute dyspnea as well as the screening of patients for congestive heart failure (CHF). Because BNP is secreted by myocytes in response to ventricular stretch, it has long been thought that BNP could become a biochemical marker for CHF. Rapid assays have been developed and BNP testing has been studied in detection of CHF and predictive outcomes in a large variety of settings.

Environmental insults: smoke inhalation, submersion, diving, and high altitude.

In the expanding search for recreation, we spend more and more of our time in various environments. Whether the air is thin or compressed or smoke-filled or there is no air at all, emergency physicians continue to meet and treat the various pulmonary emergencies that the environment may create. The authors present the background, diagnosis, and management of a few of the more common pulmonary emergencies that the environment may produce.
