Media Examines U.S. Government's Steps To Lift HIV Travel Ban
The New York Daily News on Friday examined the federal government"s recent actions to remove HIV from the list of diseases that can bar foreign residents from entry into the U.S. According to the Daily News, "The current regulations took effect in 1987, at the height of the worldwide AIDS scare," but, "[n]ow, with the backing of the Obama administration, the ban could be lifted by the end of the year." Martin Cetron, director of the CDC"s Division of Global Migration and Quarantine, said, "We"re trying to end the stigma and the discriminatory practice for a disease that doesn"t warrant exclusion for coming into this country." MSNBC.com reports that "immigration critics say they"re leery of the proposal that could allow an average of 4,275 HIV-infected people into the country annually, with a lifetime medical cost of about $94 million for those admitted during the first year, according to CDC estimates published this month in the Federal Register" (Aleccia, 7/17). Through Aug. 17, CDC is seeking public comment on the proposed rule to remove HIV from the list of diseases that can bar entry into the U.S. (Miller, 7/17).

Researchers Develop New And Efficient Breast Biopsy Technique

Researchers have developed a new breast biopsy technique that could lead to decreased procedure times and reduced patient discomfort and morbidity, according to a study performed at Roberts Research Institute, the University of Western Ontario and London Health Sciences Centre, London, ON, Canada. The new technique uses a mechanical arm to guide the needle for the biopsy and has a braking system to allow for accurate placement of the needle and to avoid needle motion. Breast biopsy procedures, using both methods, were performed on phantoms during the study. "Our results showed that biopsy success rates were greater when using our new guidance system," said Aaron Fenster, MD, lead author of the study. "We also showed that experienced and inexperienced radiologists performed a biopsy significantly faster when using our needle guidance system," said Dr. Fenster. The success rate using the needle guidance system was 95.9% compared to a success rate of 91.3% using the freehand technique. Using the freehand technique, experienced radiologists had a procedure time of approximately 31 seconds. Using the needle guidance system, experienced radiologists had a procedure time of approximately 10 seconds. "Techniques for improving biopsy procedures are needed to make the procedures more efficient and reduce the variability due to physician experience and size of the target lesion. Breast biopsy using the developed needle guidance system is feasible and I believe it will enable physicians to diagnose early-stage carcinomas more efficiently and accurately, thus decreasing patient morbidity," said Dr. Fenster. "The system we designed is a prototype and is required to be redesigned for routine clinical use. Tests with human subjects are planned for the fall of 2009," he said. This study appears in the June issue of the American Journal of Roentgenology. About ARRS The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Rē¶entgen, who discovered the x-ray in 1895. American Roentgen Ray Society
