Boston surgeons who have successfully transplanted donor faces and hands onto badly disfigured patients are now evaluating several amputees for leg transplants, a highly experimental operation believed to have been done just twice around the world, and never in the United States.

Brigham and Women’s Hospital approved the leg transplant protocol in February. Surgeons initially would perform double-leg transplants only.

Brigham surgeons already had started screening candidates for the transplants when the April 15 Boston Marathon bombing sadly created another group of badly injured patients. The bombs tore off the legs of 16 spectators; two of them lost both legs.

Dr. Matthew Carty, surgical leader of the Brigham program, said some of the Marathon victims could eventually be considered for the procedure.

A warning to parents and health care providers in Massachusetts from a poison control specialist in Colorado: As the use of medical marijuana becomes more prevalent, so too do reports of young children inadvertently ingesting the drug and ending up in the hospital.

When the number of people approved to purchase marijuana for medical use increased sharply in Colorado in 2009 officials witnessed a jump in the number of calls to poison control centers about children inadvertently eating marijuana-laced products, such as brownies, cookies, and candies, according to a study published online Monday by JAMA Pediatrics.

Marijuana-infused products have become popular for patients who are unable, or do not want, to smoke the drug.
