The list of reasons you shouldn’t smoke has gotten longer. Researchers at Washington University School of Medicine in St. Louis are reporting that smoking interferes with ligament healing. Each year in the United States there are more than 20 million reported ligament injuries, and MCL injuries—which affect a ligament supporting the knee joint—are the most common. Studying mice with MCL injuries, the team discovered cigarette smoking impairs the recruitment of cells to the injury site and delays healing following ligament repair surgery.

An X-ray of a case of scoliosis.Physicians have recognized scoliosis, the abnormal curvature of the spine, since the time of Hippocrates, but its causes have remained a mystery — until now. Researchers at Washington University School of Medicine in St. Louis and collaborating institutions have discovered a gene that underlies the condition, which affects about three percent of all children. The finding lays the groundwork for determining how the genetic defect leads to the C- and S-shaped curves that characterize scoliosis.

Scientists revealed in November 2006 that stress increases production in mice of a brain peptide critical to Alzheimer’s disease. Now the same group has shown that blocking a different brain peptide slows the stress-induced increase, opening a new door to treatment. Researchers from the School of Medicine report the results online this week in the Proceedings of the National Academy of Sciences.

The School of Medicine has received a $2.5 million grant to provide medical care to low-income and underserved adults living with HIV. The five-year grant, from the U.S. Department of Health and Human Services, was awarded through the Ryan White HIV/AIDS Treatment Modernization Act.

A simple personality test could help doctors more quickly detect dementia with Lewy bodies, a form of dementia often confused with Alzheimer’s disease, according to a study led by researchers at the School of Medicine. Dementia with Lewy bodies is the second most common neurodegenerative cause of dementia. It shares many characteristics with both Alzheimer’s and Parkinson’s disease.
