OnabotulinumtoxinA for Bladder Problems; Older Cancer Patients Not Getting Full Treatment; Vitamin B Reduces Diabetic Neuropathy

OnabotulinumtoxinA is thought of mostly as a treatment for facial wrinkles, but it's also approved for other medical conditions, including cervical dystonia; chronic migraine; and now, overactive bladder (OAB), a condition in which the bladder squeezes too often or without warning. OnabotulinumtoxinA, injected into the bladder, blocks the transmission of nerve impulses to the bladder muscle, calming contractions, which helps increase the bladder's storage capacity. It also reduces episodes of urinary incontinence.
