(Press-News.org) First large prospective study to analyze rate of adverse events
No risk of serious adverse events, less than 1 percent minor problems
Fillers, neurotoxins, laser, energy device procedures exceedingly safe
Minimally invasive cosmetic procedures can be mixed to give significant cosmetic boost
CHICAGO --- Minimally invasive cosmetic procedures, including fillers, neurotoxins and laser and energy device procedures are exceedingly safe and have essentially no risk of serious adverse events, reports a new Northwestern Medicine® study that analyzed more than 20,000 procedures around the country.
This is believed to be the first large, multi-center study that prospectively analyzed the rate of adverse events among tens of thousands of cosmetic procedures done at many centers around the United States by experienced dermatologists. These procedures are used to decrease the visible facial signs of aging.
When side effects -- such as bruising, redness, swelling, bumpiness or skin darkening – occur, they are usually minor and go away on their own, the authors report. Such minor adverse events occurred in fewer than 1 percent of patients.
For many years, there was a perception that minimally invasive cosmetic procedures are safer than larger, more invasive cosmetic procedures. However, there was little evidence to back up this belief.
The new study, published in JAMA Dermatology Nov. 5, was led by Murad Alam, M.D., professor of dermatology at Northwestern University Feinberg School of Medicine and a physician at Northwestern Memorial Hospital.
"The message for patients is that if you are thinking of getting one of these procedures, you are not indulging in something drastic or high risk," Alam said. "The take home is these procedures are very safe and can be mixed and matched to give the individual a significant cosmetic benefit, rather than getting one big cosmetic procedure that might be risky."
Previous studies have been small (typically one physician looking at his or her own data) and retrospective, in which practitioners are asked to look back over the last year or years to determine complications. That approach tends to result in underestimates because physicians can't remember and have a natural bias to not remember bad things even if they are trying to be accurate, Alam said. In addition, the critical data may not be available on the chart.
The Northwestern study looked at results of 20,399 procedures performed by 23 board-certified dermatologists at eight centers (private and institutional dermatology out-patient clinics) around the country prospectively during a three-month period per center, staggered over nine months to adjust for seasonal variation.
Physicians were asked to enter information into a central computer database on a daily basis. They entered how many procedures they performed each day, the type of procedure, whether a procedure had any complications and the nature of those complications.
Then the authors divided up the data by type of procedure to get the separate complication rate for each type of filler, laser or energy device and neurotoxin.
While all the adverse rates were low, the rates for fillers -- .52 percent -- were slightly higher than those for energy devices and neurotoxins. However, this is to be expected, the authors said, because in the world of non-invasive and minimally invasive procedures, fillers are slightly more invasive than lasers and neurotoxins.

Few adverse events found in noninvasive, minimally invasive cosmetic procedures
2014-11-05
A tiny fraction of adverse events occurred after dermatologists performed more than 20,000 noninvasive and minimally invasive cosmetic procedures, according to a study published online by JAMA Dermatology.
Cosmetic dermatology is a well-developed field and data suggest the procedures are associated with a low rate of adverse events, according to background information in the study.
Researcher Murad Alam, M.D., M.S.C.I., of the Feinberg School of Medicine at Northwestern University, Chicago, and co-authors characterized the incidence of adverse events associated with ...
Analyzing heat waves -- new index allows predicting their magnitude
2014-11-05
JRC scientists have developed a new index to measure the magnitude of heat waves, in cooperation with colleagues from five research organisations. According to the index projections, under the worst climate scenario of temperature rise nearing 4.8⁰C, extreme heat waves will become the norm by the end of the century. Heat waves like the one that hit Russia in summer 2010, the strongest on record in recent decades, will occur as often as every two years in southern Europe, North and South America, Africa and Indonesia.
The Heat Wave Magnitude Index is the first to ...
Young patients with newly diagnosed colorectal cancer anticipated to nearly double by 2030
2014-11-05
November 5, 2014 – In the next 15 years, more than one in 10 colon cancers and nearly one in four rectal cancers will be diagnosed in patients younger than the traditional screening age, according to researchers at The University of Texas MD Anderson Cancer Center. This growing public health problem is underscored by data trends among 20- to 34-year-olds in the U.S., among whom the incidence of colon and rectal cancer (CRC) is expected to increase by 90% and 124.2%, respectively, by 2030.
Published in the current issue of JAMA Surgery, the findings build on prior ...
The female nose always knows: Do women have more olfactory neurons?
2014-11-05
Rio de Janeiro, Brazil -Individuals show great diversity in their ability to identify scents and odors. More importantly, males and females greatly differ in their perceptual evaluation of odors, with women outperforming men on many kinds of smell tests.
Sex differences in olfactory detection may play a role in differentiated social behaviors and may be connected to one's perception of smell, which is naturally linked to associated experiences and emotions. Thus, women's olfactory superiority has been suggested to be cognitive or emotional, rather than perceptual. ...
Allina Health heart procedure complications reduced with simple tool
2014-11-05
MINNEAPOLIS – (November 5, 2014) – Every year in the U.S., 600,000 heart procedures are performed by threading thin tubes through patients' arteries to access their hearts. Percutaneous coronary intervention – or PCI – is an alternative to open heart surgery for many common heart problems.
But bleeding from the insertion site from blood thinners used during the procedure is a common complication of PCI, occurring two to six percent of the time.
"That might not sound serious, but bleeding is associated with adverse events, including death," said ...
Having a Y chromosome doesn't affect women's response to sexual images, brain study shows
2014-11-05
Women born with a rare condition that gives them a Y chromosome don't only look like women physically, they also have the same brain responses to visual sexual stimuli, a new study shows.
The journal Hormones and Behavior published the results of the first brain imaging study of women with complete androgen insensitivity, or CAIS, led by psychologists at Emory.
"Our findings clearly rule out a direct effect of the Y chromosome in producing masculine patterns of response," says Kim Wallen, an Emory professor of psychology and behavioral neuroendocrinology. "It's further ...
Mosquitofish genitalia change rapidly due to human impacts

The road that connects also divides.
This dichotomy – half-century-old roads connecting portions of Bahamian islands while fragmenting the tidal waters below – leads to rapid and interesting changes in the fish living in those fragmented sections, according to a new study from North Carolina State University.
NC State Ph.D. student Justa Heinen-Kay and assistant professor of biological sciences R. Brian Langerhans show, in a paper published in the journal Evolutionary Applications, that the male genitalia of three different species of Bahamian mosquitofish ...
'Direct writing' of diamond patterns from graphite a potential technological leap
2014-11-05
WEST LAFAYETTE, Ind. – What began as research into a method to strengthen metals has led to the discovery of a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips.
"The biggest advantage is that you can selectively deposit nanodiamond on rigid surfaces without the high temperatures and pressures normally needed to produce synthetic diamond," said Gary Cheng, an associate professor of industrial engineering at Purdue University. "We do this at room temperature ...
Piglet brain atlas new tool in understanding human infant brain development
2014-11-05
URBANA, Ill. – A new online tool developed by researchers at the University of Illinois will further aid studies into postnatal brain growth in human infants based on the similarities seen in the development of the piglet brain, said Rod Johnson, a U of I professor of animal sciences.
Through a cooperative effort between researchers in animal sciences, bioengineering, and U of I's Beckman Institute, Johnson and colleagues Ryan Dilger and Brad Sutton have developed a magnetic resonance imaging (MRI) based brain atlas for the four-week old piglet that offers a three-dimensional ...
Expansion of gambling does not lead to more problem gamblers, study finds
2014-11-05
BUFFALO, N.Y. – In the past decade, online gambling has exploded and several states, including New York, have approved measures to legalize various types of gambling. So, it's only natural that the number of people with gambling problems has also increased, right?
Wrong, say researchers at the University at Buffalo Research Institute on Addictions (RIA).
"We compared results from two nationwide telephone surveys, conducted a decade apart. We found no significant increase in the rates of problem gambling in the U.S., despite a nationwide increase in gambling opportunities," ...
