(Press-News.org) Multidrug-resistant pathogens are becoming more frequent, and the few "last resort" treatments available for infections with these bacteria have also shown an increase in use in recent years, according to a study published May 16 in the open access journal PLoS ONE.
The authors, led by Makoto Jones of the Veterans Affairs Salt Lake City Health Care System, investigated the use of two such antibiotics, polymyxins and tigecycline, in 127 Veterans Affairs medical centers between 2005 and 2010. They found that the overall use of these treatments was quite low, but that it did increase over the course of the study period. While this is the first study assessing use of these drugs in the United States on a large scale the trend is almost certainly not limited to the VA.
They also found that just eight facilities accounted for three quarters of all polymyxin use, and 26 facilities accounted for three quarters of all tigecycline use. Dr. Jones commented "The use of polymyxins, a class of relatively toxic antibiotics, has been increasing over time and appears to be a marker of very resistant bacteria. To address this potential harbinger of a growing epidemic, a clear strategy of infection control, antibiotic development, and antibiotic stewardship will be necessary."

Modeling neurological damage of a traumatic brain injury survivor
2012-05-17
In 1848, railroad worker Phineas Gage survived a severe brain injury when a tamping rod shot through his skull, resulting in significant behavioral changes. In a new study, reported May 16 in the open access journal PLoS ONE, researchers have used CT images of his skull in conjunction with MRI and connectomic brain imaging data of living subjects to reconstruct the injury and investigate which regions of the brain were affected to result in the behavioral changes.
The research team, led by John Van Horn of University of California Los Angeles, found that considerable ...

Johns Hopkins experts say psychiatry's diagnostic manual needs overhaul
2012-05-17
The Diagnostic and Statistical Manual of Mental Disorders (DSM), long the master reference work in psychiatry, is seriously flawed and needs radical change from its current "field guide" form, according to an essay by two Johns Hopkins psychiatrists published in the May 17 issue of the New England Journal of Medicine.
"A generation ago it served useful purposes, but now it needs clear alterations," says Paul R. McHugh, M.D., a professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine and co-author of the paper with Phillip R. Slavney, ...

Finnish researchers identified the cause for LGL leukemia
2012-05-17
LGL leukemia is a relatively rare, malignant blood disease of the mature T-cells and, in many cases, it is related to autoimmune diseases such as rheumatoid arthritis. The pathogenetic mechanism of the disease has been unknown and it has previously been unclear if the disease is an overreaction of the normal defense system or a malignant hematological disease.
One of the key symptoms of LGL disease is a low count of white blood cells (neutrophils), which may predispose the patients to life-threatening infections.
It was discovered that patients suffering from LGL leukemia ...
