The Great Prostate Mistake
Posted On: Monday, March 15, 2010 - 08:14 by Beverly Murphy

The inventor of the PSA test for prostate cancer screening Prof Richard Ablin, in a very recent op-ed in the NY Times, today regrets his invention and rues how it has led to a multi-billion dollar profit driven public health disaster in the USA . He writes - I never dreamed that my discovery four decades ago would lead to such a profit-driven public health disaster. The medical community must confront reality and stop the inappropriate use of P.S.A. screening. Doing so would save billions of dollars and rescue millions of men from unnecessary, debilitating treatments.

Posted On: Thursday, February 11, 2010 - 12:10 by Beverly Murphy

The definition, diagnosis and recommended treatment for some medical disorders are in the process of revision. After 16 years, the American Psychiatric Association wants to update the bible of psychiatry, the Diagnostic and Statistical Manual of Mental Disorders universally known as the DSM.

The new draft of DSM-V includes important changes to bipolar disorder, binged eating, autism and substance abuse, changes that affect not only mental health professionals and their patients but the insurance companies that also use the DSM as a guide.

Over the years, the DSM has generated controversy and criticism for what it defines as a medical disorder and what it doesn't.

New AHRQ Study Finds Failure to Order Needed Tests a Leading Cause of Diagnostic Errors
Posted On: Wednesday, January 20, 2010 - 10:17 by Beverly Murphy

AHRQ researchers found that failure to order tests, report results to patients, or follow up with abnormal test findings are leading types of diagnostic errors. Results were based on a survey issued to nearly 300 primary care and specialist physicians who reported 583 cases of diagnosis error, the largest-ever study of diagnostic errors in medicine. Researchers also found that tests were overlooked because clinicians often failed to consider the diagnosis, leading to delays in ordering the tests or making the correct diagnosis. The most common missed or delayed diagnoses include pulmonary embolism, drug reactions or overdose, lung cancer, colorectal cancer, acute coronary syndrome, including heart attack, breast cancer and stroke.

The study, led by Gordon Schiff, M.D.,... MORE

JAMA focuses on fallout over Breast Cancer Screen Recommendations
Posted On: Wednesday, January 13, 2010 - 08:48 by Beverly Murphy

Several commentaries in this week's JAMA (january 13, 2010) focus on the controversial 2009 U.S. Preventive Services Task Force recommendations on breast cancer screening. In one, a former member of the task force reminds readers that the organization does not represent the government. He faults the recommendation's "poor wording" as one cause of the controversy and observes that it was "unwise" for the task force not to plan for the inevitable political fallout. In another brief essay, two experts in health outcomes research examine the real harms of overdiagnosis and decry the politicization of healthcare. "Promoting screening irrespective of the evidence may garner votes," they write, "but will not create healthier voters." There are... MORE

Free tool helps calculate return on investment from better asthma care

Antidepressant Drug Effects and Depression Severity
A Patient-Level Meta-analysis

Jay C. Fournier, MA; Robert J. DeRubeis, PhD; Steven D. Hollon, PhD; Sona Dimidjian, PhD; Jay D. Amsterdam, MD; Richard C. Shelton, MD; Jan Fawcett, MD
JAMA. 2010;303(1):47-53.

This meta-analysis looks at six large trials, three of Paxil and three of imipramine, and shows that the effectiveness of the drugs varies according to the level of severity of depression. While the drugs are effective for severe depression, they offer little to no benefit over placebo for mild to moderate depression.
