ThoelkeIn today’s era of managed care, most physicians have fewer inpatients, and that makes it hard for many to justify spending time at the hospital with those patients. Mark S. Thoelke, M.D., clinical director of the hospitalist service at Barnes-Jewish Hospital and assistant professor of medicine at Washington University School of Medicine in St. Louis, says because hospitalist physicians do not maintain outpatient practices, they can spend all of their time in the hospital and are available to treat a wide range of patients. That also allows for improvements in outpatient care because with their inpatients cared for by hospitalists, primary care physicians can focus even more of their time on the needs of the outpatients who make up the vast majority of their practices.

Sometimes two shots are better than one. Washington University pediatrician, Robert M. Kennedy, M.D., professor of pediatrics, and other Emergency Department researchers at St. Louis Children’s Hospital, have developed an “ouchless” IV technique. Before inserting a big IV needle into the hand of a child, the physicians first apply numbing gel. Then, they use a tiny needle to inject a local anesthetic into the area before they finally introduce the bigger IV needle. By the time an IV is started, the injection site is numb, and patients who already are in an emergency department, don’t have to face even more pain.

Sophisticated brain imaging reveals that several brain regions can become overactivated when people with Tourette Syndrome perform tasks related to memory.Neuroscience researchers at Washington University School of Medicine in St. Louis are studying the brains of patients with Tourette Syndrome (TS) to see whether they can use sophisticated imaging techniques to identify differences in the dopamine system of people with the tics that characterize TS. A team of researchers, led by Kevin J. Black, M.D., assistant professor of psychiatry, neurology and radiology at Washington University School of Medicine, is using PET imaging to see what the brain does in response to levodopa, a natural amino acid that has been used for many years to treat movement disorders, such as Parkinson’s disease. With PET imaging, the researchers can measure the boost in the brain’s dopamine levels in response to the drug both in people with Tourette Syndrome and in those who do not have tics. By identifying differences, they hope to isolate the causes of tics and to help people with TS control or eliminate them.

Illustration from a Hans Christian Andersen story.What is “children’s literature?” As we pause between the perfect, all-ages storms of Harry Potter and the Order of the Phoenix and the upcoming Lord of the Rings: Return of the King film adaptation, the answer seems less clear than ever. In the current issue of Belle Lettres, a bi-monthly publication of Washington University’s International Writers Center in Arts & Sciences, a culture critic and a director of teacher education explain that the genre, always hard to define, remains poorly understood and frequently underestimated.

Next time you think “oil spill,” remember that the vegetable oils used to make Freedom fries also can create an environmental mess.

Older workers enrolled in a computer training class.Some economists predict that by 2030, the United States could experience a labor shortage of 35 million workers. Many businesses, including retail giants such as Wal-Mart and McDonalds, have responded to a looming labor shortage by encouraging older workers to remain in the workforce. But a recent study issued by the U.S. General Accounting Office finds that many of the government’s existing employment assistance programs are not providing computer training and other high-tech skills to workers over the age of 55, a demographic that may soon constitute roughly one-third of the entire American workforce. Nancy Morrow-Howell, Ph.D., a professor of social work at Washington University in St. Louis and a leader in the emerging field of productive aging research, contends that America’s economic future may well hinge on our ability to help older adults continue making contributions to society.

That’s a theory proposed by Erik Herzog, Ph.D. assistant professor of biology in Arts & Sciences at Washington University in St. Louis. Herzog has found that the biological clocks of rats and mice respond directly to temperature changes.

The discovery is completely unexpected and challenges the way evolutionary biologists think of evolution.

O’SullivanAn electrical engineer at Washington University in St. Louis has devised a theory that sets the limits for the amount of data that can be hidden in a system and then provides guidelines for how to store data and decode it. Contrarily, the theory also provides guidelines for how an adversary would disrupt the hidden information. The theory will have a major impact on homeland security applications.

Experimental economics — a fast-growing branch of economics that involves the creation of a microeconomic environment in a laboratory — is being widely used at the John M. Olin School of Business. Applications of the experimental research have multiplied, spanning many industries and producing results that have impacted everything from how airlines price their tickets to how companies manage their employees. Ronald R. King, Ph.D., is helping to lead the burgeoning new area of research at the business school.
