Summary:
In younger patients, the estimated radiation risks associated with abdominal and pelvic computed tomography scans are twice those of older patients, according to a new study.

In younger patients, the estimated radiation risks associated with abdominal and pelvic computed tomography (CT) scans are twice those of older patients, according to a study to be presented at the American Roentgen Ray Society 2010 Annual Meeting in San Diego, CA.

"Estimating the risks associated with ionizing radiation is complex," said James Koonce, MD, lead author of the study. "Many variables such as patient size, age, and the region of the body being imaged all effect the total risk. Our study looked at how the overall risks associated with abdominal/pelvic CT scans depend on patient sex and age," said Koonce.

The study, performed at the Medical University of South Carolina in Charleston, SC, included 51 patients who underwent routine contrast-enhanced abdominal and pelvic CT examinations. "We found that the estimated radiation risk for a 31 year old (0.91 per 1,000) was about double that for a 74 year old (0.47 per 1,000). The median radiation risk to 25 males was 0.61 per 1,000 and for 26 females was 0.74 per 1,000," said Koonce.

"Clinicians ordering imaging tests must use their best clinical judgment to select patients with a reasonable pre-test probability that the diagnosis afforded by CT will give valuable information to effect patient management," he said.

"Knowing the risk involved with radiation exposure to a patient during an abdominal/pelvic CT allows for more accurate risk benefit evaluation when a physician is deciding whether or not to order an exam," said Koonce.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
