OAK BROOK, Ill. -- November 23, 2009 -- In the November issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE), a study out of Stanford University found that Barrett's esophagus was detected in six percent of asymptomatic women undergoing endoscopic screening.
HOUSTON - (Nov. 20, 2009) -- The addition of a "genetic sonogram" maximizes the accuracy of non-invasive testing for Down syndrome, said a Baylor College of Medicine researcher who was lead author of a landmark study in the current issue of Obstetrics and Gynecology.
Spot blood pressure readings in children with chronic kidney disease often fail to detect hypertension -- even during doctor's office visits -- increasing a child's risk for serious heart problems, according to research from Johns Hopkins Children's Center and other institutions. A report of the findings appears online in the Journal of American Society of Nephrology.
To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins.
New Mayo Clinic research studied the association between prostate-specific antigen (PSA) levels and prostate size and found that routine annual evaluation of prostate growth is not necessarily a predi
When a fetus is smaller than expected for the number of weeks of pregnancy, due to associated problems like a poorly developed heart, health concerns as severe as brain damage can result.
New Rochelle, NY, November 5, 2009 -- The American Thyroid Association has released new, revised Management Guidelines for the diagnosis and treatment of patients with thyroid nodules and thyroid c
Longer toes and a unique ankle structure provide sprinters with the burst of acceleration that separates them from other runners, according to biomechanists.
BERKELEY, CA -- Ultrasound and underwater sonar devices could "see" a big improvement thanks to development of the world's first acoustic hyperlens. Created by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), the acoustic hyperlens provides an eightfold boost in the magnification power of sound-based imaging technologies.
AUGUSTA, Ga. -- Thyroid surgery is safe for older patients, say physicians who found only slight differences in rates of complications and hospital readmissions in a multi-year study.
Clinical researchers at Princess Margaret Hospital (PMH) can now answer the question that baffles many clinicians -- why do some men with elevated prostate specific antigen (PSA) levels who are carefully monitored and undergo repeated negative biopsies still develop aggressive prostate cancer?
Chaotic behavior is the rule, not the exception, in the world we experience through our senses, the world governed by the laws of classical physics.
Even tiny, easily overlooked events can completely change the behavior of a complex system, to the point where there is no apparent order to most natural systems we deal with in everyday life.
The National Institute of Standards and Technology (NIST) has unveiled a method for calibrating entire waveforms -- graphical shapes showing how electrical signals vary over time -- rather than just parts of waveforms as is current practice.
Newport Beach, Calif. -- October 5, 2009 -- A special report published in the October issue of the Journal of the American College of Surgeons indicates that an alarming 35% of initial diagnostic breast biopsies in the United States are still being done using unnecessary open surgical techniques.
SAN FRANCISCO, CA -- SEPTEMBER 24, 2009 -- Late-breaking results from the PROSPECT clinical trial shed new light on the types of vulnerable plaque that are most likely to cause sudden, unexpected adverse cardiac events, and on the ability to identify them through imaging techniques before they occur.
