A Woman Grows Bones Out of Her Eyes After Stem Cell Face-Lift
Plus: Lubricant study shows higher STD risk; Amoxicillin not effective; and more health headlines.
A woman gets a $20,000 “stem cell face-lift” in Beverly Hills. Three months later, bones are growing out of her eyes. The¬†mesenchymal stem cells used in the face-lift can turn into bone, cartilage, or fat, among other tissues. It was mixed with her own fat and injected back into her face, especially around her eyes.¬†Her doctors also injected some dermal filler, used safely for more than 20 years to reduce the appearance of wrinkles. The main component of the fillers is calcium hydroxylapatite, a mineral with which can turn mesenchymal stem cells to turn into bone‚ÄĒa fact that escaped the woman’s clinicians.¬†It took six and a half hours of surgery to get the bone growth¬†out¬†of her eyes. You can’t make this stuff up. [Scientific American]
Personal lubricant study shows that lubricants can increase risk for diseases like herpes and chlamydia.¬†After examining mouse vaginal cells, the researchers discovered that when the mice were exposed to high-osmolality (a¬†parameter describing the overall concentration of molecular ingredients in a product) lubricants followed by herpes simplex virus, the rodents were more susceptible to infection.¬†For example, K-Y Warming Jelly, which has an osmolality more than 30 times the body‚Äôs own fluid, increased herpes transmission more than ninefold in rodents.¬†And women everywhere sigh in disbelief.

Amoxicillin¬†is not effective in treating sinus infections when tested against a placebo, according to a new study published in The Lancet. We’ve all taken this¬†antibiotic¬†countless times. Researchers recruited 2,061 patients 18 years and older (across a dozen European countries)¬†who went to their doctor for a lower-respiratory infection. Half were given Amoxicillin and half a placebo.¬†The severity and length of the symptoms were the same for both groups. [Scientific¬†American]
HIV is still a serious¬†health problem, and about 47,500 people were newly infected with the virus in the U.S. in 2010, according to the CDC. In a new report, two trends stood out: A decrease in new HIV infections among black women (21 percent decrease between 2008 and 2010),¬†and an increase in new infections among young gay and bisexual men (22 percent increase¬†over the same time period). It is troubling that with everything we know about prevention this is still a major issue. According to the report, about 50,000 new cases of HIV are diagnosed yearly since the¬†mid-1990s. [CDC]
The FDA is¬†recommending¬†new¬†rules to regulate¬†compounding¬†pharmacies after the¬†outbreak of fungal meningitis that infected 620 people and killed 39.¬†FDA officials held a meeting this week to discuss how to better regulate pharmacies.¬†A category of ‚Äėnontraditional‚Äôcompounding has evolved in the last decade that the FDA believes requires additional oversight. Included in that group is the¬†New England Compounding Center in Framingham, the pharmacy at the¬†center of the outbreak. It was¬†licensed as a compounding pharmacy, which means it was supposed to mix and distribute drugs only on an individual, prescription-by-prescription basis. But¬†investigations have shown it worked on a much larger scale. [NBC News]
