Welcome to another edition of factual Fridays. The leading health stories in the news are about polio concerns in China, more health concerns for those who have diabetes, new disease discovered, and a new FDA warning.

Outbreak Alert…There were 10 confirmed cases of poliomyelitis in China this week.  Polio, a viral infection that can lead to paralysis, was once a global epidemic. Due to a worldwide effort in the 1980s to get vaccines out, the disease was eradicated in most of the world, and several countries, including China and the U.S., were declared completely polio-free.  More at CNN.

Risk Increase…Diabetes, which has been known to increase the risk of heart attack or stroke, can add another disease to its resume.  A new study conducted in Japan found that diabetes’ patients were more than twice as likely to develop Alzheimer’s disease as control patients.  More at CNN.

New Disease Discovered…Ticks, already infamous for their role in Lyme disease, have been linked to a new illness.  Caused by Borrelia miyamotoi, the symptoms are similar to Lyme, and some speculate this may be the true culprit of chronic Lyme disease.  More at NYT.

Beauty Blunder…The Brazilian Blowout, (also called Brazilian Keratin), a common smoothing hair treatment that women get to straighten curly or wavy hair, has just been given an FDA warning.  The treatment is known to contain dangerously high levels of formaldehyde, a well-known carcinogen, and companies have been ordered to reduce the amount of chemicals or pull the product from the market altogether.   Formaldehyde is considered a hazard at levels above 0.1%, and Brazilian blowouts contain between 8.7% and 10.4% of the carcinogen.  More at WebMD
