Adult hospitals overuse CT for appendicitis in kids
By Abraham Kim
Children with suspected appendicitis were nearly three times as likely to undergo a CT exam at a nonpediatric facility than at a pediatric hospital in recent study, published online in the Journal of Surgical Research. Ultrasound might have provided a radiation-free alternative to CT, the researchers noted.

Earlier colon screening saves lives -- but at what cost?
By Abraham Kim
Lowering the starting age for colorectal cancer screening from 50 to 45 is a cost-effective strategy to reduce cancer deaths, but improving uptake among those currently eligible would provide even greater benefits, according to U.S. researchers who used a math model to project the outcomes in a study published March 28 in Gastroenterology.

Cancer death rates decline, but economic gap remains
By Kate Madden Yee
The overall cancer death rate in the U.S. dropped by 27% over the past 25 years, but more needs to be done to reduce deaths among Americans of lower socioeconomic status, according to a report from the American Cancer Society published online January 7 in CA: A Cancer Journal for Clinicians.
