Surgery and other treatments offer viable options for adult scoliosis

For years, spine surgeons have debated the best methods for treating scoliosis in adults. Spinal curvature often results in more back pain, leg pain and other symptoms for adults than teens because adults also can have degeneration in the discs between vertebrae, and spinal stenosis -- a narrowing of the opening for the spinal nerves.

Researcher explore why some patients recover quickly after surgery while others don't

Why do some patients recover quickly after surgery, while others don't? That is an important question when treating older frail patients suffering from aortic stenosis. Lead author Dae Hyun Kim, M.D., M.P.H., Sc.D., and principle investigator Director Lewis A. Lipsitz in the Marcus Institute for Aging Research at Hebrew SeniorLife explore this question in a paper published today in the Journal of the American Medical Association Internal Medicine.

Gerontologists assess change in patients' functional status after valve replacement procedure

Affecting an estimated one in eight people older than 75, aortic valve stenosis - a narrowing of the heart's main artery - makes the heart work harder to supply the body with blood, potentially limiting patient's activity levels an quality of life. Ultimately, aortic stenosis can lead to stroke, arrhythmia, heart failure and death.

Most patients who underwent transcatheter valve replacement experience prosthesis-patient mismatch

In the largest multi-institutional study to date, led by researchers from Penn Medicine, the team found that among patients who underwent a transcatheter aortic valve replacement, a high number experienced severe and moderate cases of prosthesis-patient mismatch--meaning the implanted heart valve is too small for the patient which can lead to inadequate blood flow.
