Community MRSA is re-emergence of 1950's pandemic
This "re-equipping and re-emergence" of a clone that caused a pandemic 40-50 years ago could mean that community acquired MRSA will spread faster and be more widespread than previously expected, warns an international team of researchers who have been studying the bacteria.  more

Advanced prostate cancer previously considered inoperable may be operable, curable

Two-part blood pressure control suggests new approach to hypertension therapy
The kidneys have long been known to play a major role in many cases of high blood pressure, but a new study by researchers at Duke University Medical Center reveals that the body's control of blood pressure depends as much on other organs in the body. The researchers said the findings about a "two-part system" may lead to improved methods for treating high blood pressure, which affects nearly one in three American adults.  more

Vaccine means bye-bye to Pseudomonas aeruginosa in the lung

It is therefore important to develop a vaccine against this pathogen. Appearing online on 1 April 2005 in advance of print publication of the May issue of The Journal of Clinical Investigation, Ronald Crystal and colleagues from Cornell University use a novel strategy to create a genetic vaccine against P. aeruginosa.  more

Non surgical cryoablation, "male lumpectomy" preserves function
A new nonsurgical treatment for prostate cancer preserves urinary and sexual function in a majority of men and offers an effective treatment, according to a study presented today at the Society of Interventional Radiology’s 30th Annual Scientific Meeting. The “male lumpectomy” uses focal cryoablation — freezing the tissue with extremely cold gas — to target only the tumor itself, which spares the healthy tissue in the prostate gland and associated anatomy, rather than destroying all of it as all traditional approaches do.  more
