‘Love hormone’ may reduce autism symptoms

NEW YORK (UPI) — The "love hormone," released at childbirth and during sex, is being used in a U.S. trial of young adults with Autistic Spectrum Disorders, researchers say.
Dr. Eric Hollander, the center’s advisory board chairman and chairman of the psychiatry at the Mt. Sinai School of Medicine at the Albert Einstein College of Medicine, says giving oxytocin may improve social functioning and repetitive behaviors — irrespective of the age of the patient.
"For the first time, certain core systems of autism may respond to treatment," Hollander says in a statement.
In the trial, autistic patients age 18 and older, who were given oxytocin nasally for 12 weeks significantly reduced their repetitive behavior, and were better able to recognize anger or happiness in the tone of a speaker’s voice.
Upbeat results were also provided in a similar age group who took the peptide intravenously, the study said.
Autistic Spectrum Disorders refers to a group of symptoms, like a profound inability to communicate and other developmental disorders.

Study: Soap superior to hand sanitizers

OTTAWA (UPI) — A University of Ottawa researcher has found liquid and foam hand sanitizers are inefficient if not backed up with regular soap-and-water hand-washing.
Microbiologist Jason Tetro conducted a test on schoolchildren at the request of the Canadian Broadcasting Corp. in which swabs of their hands for bacterial culture were taken before they used hand sanitizer and then after they had used it.
He said while many sanitizers claim to kill 99.9 percent of germs, results seen using three brands ranged from 46 percent fewer bacteria to 60.4 percent.
"It was very obvious which ones were washing their hands and which ones weren’t. You could see, practically, the dirt and oil buildup on their hands," Tetro told the Ottawa Citizen. "The caveat to all that is that you should be washing your hands eight to 12 times a day," or the sanitizer won’t work well."
He noted the test found the students who play sports and got dirty outdoors were more likely to wash their hands with soap than the more sedentary students, the report said.
