"It has come to our attention that a phishing email is being circulated on mock Health and Human Services Departmental letterhead under the signature of OCR's director, Jocelyn Samuels," said OCR in the alert. "This email appears to be an official government communication, and targets employees of HIPAA-covered entities and their business associates.
"The email prompts recipients to click a link regarding possible inclusion in the Health Insurance Portability and Accountability Act Privacy, Security, and Breach Rules Audit Program," the alert continued. "The link directs individuals to a non-governmental website marketing a firm's cybersecurity services. In no way is this firm associated with the U.S. Department of Health and Human Services or the Office for Civil Rights."
OCR urged organizations or individuals with questions about official agency communications regarding HIPAA audits to contact the office via email at OSOCRAudit@hhs.gov.
For more information about phishing scams, the Federal Trade Commission website has a resources page here and also has a page with tips for consumers.
The ADA Center for Professional Success also has tips to help ADA member dentists safeguard their practice from hackers.

When I was younger, I used to love to snow ski. Back in the good old days before age set in, I would fly down the slopes with little concern for personal safety. Maybe that’s why I got a couple of concussions along the way…
Of course, back then all I had on my head was a hat which wasn’t too good at providing protection when I fell. The last time I hit the slopes, a couple of years ago, everyone was in helmets, myself included.
Protecting yourself is important, but think about the risk that is taken by professional Olympic skiers.
They are skiing at ridiculous speeds and when they fall, it’s just like a motorcycle crash on hard packed snow. Needless to say, the art of protection needs to evolve to protect all of us, and now it has.
The Giro folks have created a fascinating helmet that isn’t just a padded lining in a very hard shell.
Take a look at the video above.
Then if you want more info on Giro gear, head to the website.

Ancient', 'green', or 'borrowed from other people' aren't descriptors many of us would want used to describe our pearly whites.
But all three are apt for a set of dentures unearthed from a chapel in Italy, which could date back to the time of Leonardo Da Vinci.
Archaeologists believe the prosthesis, which is made from a string of human teeth and a strip of metal, could date back as far as the 14th century - making them one of the only sets from the Renaissance period to be found.

According to English language Italian news website, The Local, the dentures were uncovered during a dig in Lucca in Italy, in the bottom layers of a tomb.
A team from the University of Pisa unearthed the Renaissance false teeth while excavating a family tomb in 2010 where hundreds of skeletons are buried in the chapel of San Francesco.
The site was the tomb for the Guinigi family, an aristocratic group of powerful bankers and traders who governed the city, with generations of Guinigi's buried atop one another.
Dental implants have been recorded as far back as the ancient Egyptians, with Romans and Etruscans also showing signs of having dental work done to fill the gaps.
The first porcelain dentures didn't arrive until the late 18th century, so animal teeth, human teeth, bone, ivory and other tough surfaces were trialled.

E-cigarettes and flavorings induce inflammatory and pro-senescence responses in oral epithelial cells and periodontal fibroblasts
Electronic-cigarettes (e-cigs) represent a significant and increasing proportion of tobacco product consumption, which may pose an oral health concern. Oxidative/carbonyl stress via protein carbonylation is an important factor in causing inflammation and DNA damage. This results in stress-induced premature senescence (a state of irreversible growth arrest which re-enforces chronic inflammation) in gingival epithelium, which may contribute to the pathogenesis of oral diseases. We show that e-cigs with flavorings cause increased oxidative/carbonyl stress and inflammatory cytokine release in human periodontal ligament fibroblasts, Human Gingival Epithelium Progenitors pooled (HGEPp), and epigingival 3D epithelium. We further show increased levels of prostaglandin-E2 and cycloxygenase-2 are associated with upregulation of the receptor for advanced glycation end products (RAGE) by e-cig exposure-mediated carbonyl stress in gingival epithelium/tissue. Further, e-cigs cause increased oxidative/carbonyl and inflammatory responses, and DNA damage along with histone deacetylase 2 (HDAC2) reduction via RAGE-dependent mechanisms in gingival epithelium. A greater response is elicited by flavored e-cigs. Increased oxidative stress, pro-inflammatory and pro-senescence responses (DNA damage and HDAC2 reduction) can result in dysregulated repair due to proinflammatory and pro-senescence responses in periodontal cells. These data highlight the pathologic role of e-cig aerosol and its flavoring to cells and tissues of the oral cavity in compromised oral health.
