Is it Bell's palsy or a stroke? Emergency physicians have the answer

26.07.2013
Emergency physicians correctly identified nearly 100 percent of patients with Bell's palsy, the symptoms of which are nearly identical to potentially life-threatening diseases such as stroke and brain tumors.

The results of a study of 6 years of California patient records were published online yesterday in Annals of Emergency Medicine ("Potential Misdiagnoses of Bell's Palsy in the Emergency Department").

"Even lacking established guidelines for diagnosing Bell's palsy, which is the most common cause of paralysis of one side of the face, emergency physicians make the right call nearly every time," said lead study author Jahan Fahimi, MD, MPH, of Alameda County Medical Center in Oakland, Calif. and the University of California, San Francisco.

"The dramatic and distressing nature of facial paralysis often brings patients to the ER for evaluation, often with a concern that they are having a stroke. The combination of thorough history-taking and detailed physical exam allows emergency physicians to determine which patients have a dangerous condition and which can safely be discharged home. While there may be a role for imaging, such as CT or MRI, the overwhelming majority of patients can be evaluated without advanced diagnostic tests."

Researchers analyzed 43,979 records for patients discharged from California emergency departments with a diagnosis of Bell's palsy. At 90-day follow up, 0.8 percent of those patients received an alternate diagnosis, such as stroke, brain bleed, brain tumor, central nervous system infection, Guillain-Barre syndrome, Lyme disease, ear infection or herpes zoster. When restricted to only life-threatening alternative diagnoses associated with central facial paralysis, only 0.3 percent were misdiagnosed.

Patients with Bell's palsy commonly manifest partial or complete weakness of the muscles of half of the face, resulting in an inability to raise one eyebrow, wrinkle their foreheads or close one eyelid. Symptoms often progress fairly rapidly and strongly mimic the symptoms of certain types of stroke. It affects approximately 15 people out of 100,000 every year.

Annals of Emergency Medicine is the peer-reviewed scientific journal for the American College of Emergency Physicians, the national medical society representing emergency medicine. ACEP is committed to advancing emergency care through continuing education, research, and public education. Headquartered in Dallas, Texas, ACEP has 53 chapters representing each state, as well as Puerto Rico and the District of Columbia. A Government Services Chapter represents emergency physicians employed by military branches and other government agencies. For more information, visit http://www.acep.org.

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
