EXCERPTED SCRIPT

"The Threat of Artemisinin-Resistant Malaria", a PERSPECTIVE article by Arjen Dondorp, from Mahidol University, Bangkok, Thailand
Since the 1970's when Chinese researchers demonstrated the artemisinins antimalarial potency, artesiminin based combination therapy has become key to malaria control. But reduced susceptibility of Plasmodium falciparum to artemisinin derivatives has been documented in the Cambodia–Thailand border region.  Although most P. falciparum infections still eventually clear after treatment with artemisinin-based combination therapies, resistant parasites take 3 or 4 days to do so, as compared with less than 2 days for artemisinin-sensitive parasites. This delayed clearance could be a step toward high-level resistance and frank treatment failure. Since the artemisinins have very short half-lives, this loss of potency also renders the more slowly eliminated drugs that are part of combination therapies vulnerable to development of resistance. The gravity of this threat has been recognized, and an ambitious program to contain artemisinin resistance has been launched under the guidance of the World Health Organization. Still, several critically important questions about artemisinin resistance and containment merit urgent attention. The artemisinins have been crucial to recent successes in reducing the malaria burden, and artemisinin-based combination therapies are essential to all plans for malaria elimination. Losing artemisinins to resistance will not only jeopardize the goal of malaria eradication, but will also result in large increases in African childhood mortality.

ABRIDGED SCRIPT

"Breast-cancer screening",
a Clinical Practice article by Ellen Warner from University of Toronto, Canada.
Mortality from breast cancer in industrialized countries has been decreasing at the rate of approximately 2.2% per year. In the United States, this decline has been attributed both to advances in adjuvant therapy and to increasing use of screening mammography. Nevertheless, the 2009 recommendations of the U.S. Preventive Services Task Force support a reduction in the use of screening mammography. This revision resulted in considerable confusion and controversy. The two most disputed changes were the reclassification of screening for women between the ages of 40 and 49 years from a B recommendation (based on moderately strong evidence) to a C recommendation (“the decision should be an individual one and take into account patient context, including the patient's values regarding specific benefits and harms”), and the recommendation that the frequency of screening be reduced from every 1 to 2 years to every 2 years. This article focuses on the updated evidence and recommendations for screening women who are at average risk for breast cancer. The most important benefits of screening are a reduction in the risk of death and the number of life-years gained. Costs include the financial costs and other costs of the screening regimen itself (radiation risk, pain, inconvenience, and anxiety), the ensuing diagnostic workup in the case of false positive results, and overdiagnosis. The ratio of benefit to cost varies significantly with the patient's age. An audio version of this article is available at NEJM.org.

"The Art of Doing Nothing"

A perspective article by Lisa Rosenbaum, a cardiology fellow at New York–Presbyterian/Weill Cornell Medical Center, New York.
Near the end of medical school, Dr Rosenbaum injured her knee running a marathon.  What began as classic “runner's knee” during training worsened when she ran the race anyway. A month later, she still couldn't run comfortably.Then one day, she felt an odd, round mass protruding from the most tender area. Was it a tear? An infection? A tumor? The only logical solution seemed to be an MRI and a referral to an orthopedist. Her primary care physician, Dr. B eyed her lump.  “It's just a simple tendon cyst, a ganglion,” he told her. “You don't need an MRI; you just need to rest.” When she faced Dr. B. again, she informed him of the expert opinion of her distant cousin, an orthopedist. “He says I need an MRI,” she said “I might have a torn meniscus or something.”
Three weeks later, she got an MRI. Dr. B. called with the results. “You have something called `lateral compression syndrome'.” She pushed her knee to the point where, on imaging, it looked like someone had repeatedly whacked her with a club. Dr. B. said he suspected the orthopedist would recommend surgery.“But Dr. B.,” Dr Rosenbaum said, “don't you think I just need to rest?” Of course, in the end Dr. B. had been right all along; proper rest was all she ever needed.
Dr Rosenbaum writes: What a culture values may be constantly in flux, but it is still up to us to determine. We may choose to value an MRI more than the wisdom and experience of our physicians, but this does not mean that an MRI is inherently more beneficial to our health.
