For chronic pain sufferers, such as people who develop back pain after a car accident, avoiding the harmful effects of stress may be key to managing their condition. This is particularly important for people with a smaller-than-average hippocampus, as these individuals seem to be particularly vulnerable to stress. These are the findings of a study by Dr. Pierre Rainville, PhD in Neuropsychology, Researcher at the Research Centre of the Institut universitaire de griatrie de Montral (IUGM) and Professor in the Faculty of Dentistry at Universit de Montral, along with tienne Vachon-Presseau, a PhD student in Neuropsychology. The study appeared in Brain, a journal published by Oxford University Press.
"Cortisol, a hormone produced by the adrenal glands, is sometimes called the 'stress hormone' as it is activated in reaction to stress. Our study shows that a small hippocampal volume is associated with higher cortisol levels, which lead to increased vulnerability to pain and could increase the risk of developing pain chronicity," explained tienne Vachon-Presseau.
As Dr. Pierre Rainville described, "Our research sheds more light on the neurobiological mechanisms of this important relationship between stress and pain. Whether the result of an accident, illness or surgery, pain is often associated with high levels of stress Our findings are useful in that they open up avenues for people who suffer from pain to find treatments that may decrease its impact and perhaps even prevent chronicity. To complement their medical treatment, pain sufferers can also work on their stress management and fear of pain by getting help from a psychologist and trying relaxation or meditation techniques."
Research summary
This study included 16 patients with chronic back pain and a control group of 18 healthy subjects. The goal was to analyze the relationships between four factors: 1) cortisol levels, which were determined with saliva samples; 2) the assessment of clinical pain reported by patients prior to their brain scan (self-perception of pain); 3) hippocampal volumes measured with anatomical magnetic resonance imaging (MRI); and 4) brain activations assessed with functional MRI (fMRI) following thermal pain stimulations. The results showed that patients with chronic pain generally have higher cortisol levels than healthy individuals.
Data analysis revealed that patients with a smaller hippocampus have higher cortisol levels and stronger responses to acute pain in a brain region involved in anticipatory anxiety in relation to pain. The response of the brain to the painful procedure during the scan partly reflected the intensity of the patient's current clinical pain condition. These findings support the chronic pain vulnerability model in which people with a smaller hippocampus develop a stronger stress response, which in turn increases their pain and perhaps their risk of suffering from chronic pain. This study also supports stress management interventions as a treatment option for chronic pain sufferers.

Cross-dressing teen told he can?t wear chic red dress, pumps and wig to prom
In the latest high school prom-related kerfuffle to make a national splash, a cross-dressing Texas high school student is at odds with school officials because he wants to wear a red dress, black heels and a blond wig to the big dance.
The student, senior Tony Zamazal, says he feels more comfortable wearing women?s clothing. He wants to make a dashing debut on Spring High School?s biggest stage, reports KHOU, the local CBS affiliate.
However, Zamazal says, the assistant principal at the high school in the suburbs of Houston quickly put the kibosh on the idea.
?He told me it just wasn?t in the dress code. [He said] women wore dresses, and men wore tuxedos,? Zamazal the CBS affiliate.
A school district representative was unable to verify that the school actually has such a dress code. However, the official told the station that Zamazal can appeal the assistant principal?s denial to the principal.
It?s not clear if Zamazal has made such an appeal.
?If I do get to go as a woman, I will be ecstatic,? the senior told KHOU. ?If I don?t, it would be devastating, because I put myself out there.?
?It?s not okay to just tell people, they can?t be the way that they are,? he added.
This case of cross-dressing is at least the third prom-related brouhaha to surface in the United States in the last few weeks.
A group of parents and students in rural Sullivan, Indiana made news for their attempt to raise money for a private prom which would exclude gay students.
Diana Medley, a teacher at a nearby school who was involved in that effort, was suspended from her job for telling a local television station that gays have no purpose in life.
The superintendent of a tiny school district in southeast Missouri said the local high school would yield to a gay male student?s request to bring his boyfriend to the prom after the Southern Poverty Law Center threatened legal action.

MIT on lockdown after reports of armed gunman
BOSTON (AP) ? The Massachusetts Institute of Technology says a man carrying a long rifle and wearing body armor was spotted in a campus building, and the school is on lockdown.
MIT said in a statement Saturday that several law enforcement agencies have responded, and a photo that appears to have been tweeted from near campus shows a road blocked to traffic.
The school advises students and workers to stay indoors and report suspicious activity to campus police.
More details were not immediately available.

Chrome Pixel: Google Unveils Premium Touchscreen Laptop
? ?
The Chromebook Pixel, a slim laptop with a 12-inch, 2560 x 1700 pixel touchscreen, features just 2GB of RAM, a 32GB sold-state hard drive and an Intel (NASDAQ:INTC) Core i5 chip. Pricing for the?Pixel begins at $1,300, ABC News notes.
With the a limited amount of hard drive space, Google is offering 1TB of free cloud-based storage to Chromebook Pixel buyers. Additional cloud-storage can be purchased, if needed. A Chromebook Pixel with built-in LTE connectivity will be offered for $1,449.
A number of othe companies, including Hewlett-Packard (NYSE:HPQ) and Samsung already make Chrome-based laptops, most priced under $500. Google is betting that consumers will be attracted to the Pixel?s high resolution screen.
Some experts aren?t so sure. An analyst at Reticle Research told ABC News that many consumers would likely find it hard to justify such a high price for a laptop that could not serve as their primary computer.
Shares of Google rose fractionally in pre-market trading on Friday.

Red Sox prospects romp against Boston College
FORT MYERS, Fla. ? An ensemble of Red Sox minor leaguers that included some of the top prospects in the organization cruised to an 11-1 seven-inning victory over Boston College.
Catcher Dan Butler blasted a two-run homer over the 40-feet high wall in JetBlue Park as part of an eight-run third inning that also included an RBI double by Jackie Bradley Jr., a two-run double by Jonathan Diaz and a two-run single by Mauro Gomez.
Gomez paced the offense by going 3-for-3 with a double while driving in two runs. Bradley had an opportunity to display his all-fields approach, lining out to center on a 2-2 pitch in his first at-bat, launching a 1-0 fastball off the base of the fence in left-center in his second plate appearance and lining out to left field in his third at-bat. Outfielder Shannon Wilkerson later added a two-run homer to left.
Xander Bogaerts went 1-for-4 (dribbler to third, lineout to center, liner to deep left that required a nice leaping catch by the Boston College left fielder, and a double to left-center), and more notably, had a successful first game at third base, handling both groundballs that were hit to him including a nice play on a grounder to his left. Still, the novelty of the hot corner was apparent, as he sought advice from the dugout to help position him.
An ensemble of Red Sox relievers limited Boston College to one run on three hits. Koji Uehara worked around a pair of first-inning singles to record a scoreless first, while Andrew Bailey recorded a shutout second inning before Junichi Tazawa gave up the lone run of the game in the third. Oscar Villareal, Jose De La Torre and BC alum Terry Doyle all contributed with scoreless frames before Brock Huntzinger closed it out.
The Sox now have a short workout on Friday before they commence official Grapefruit League play on Saturday against the Rays.
Here?s video of Bogaerts? double:

NBA Trade Deadline Watch: Counting Down to 3 p.m. with the Still-Middling Sixers
Feb 21, 2013 12:00pm
By Nick Menta, (email)
The700Level.com
The NBA trade deadline is set for 3 p.m. this afternoon.
This, typically, is one of my favorite days of the year, because there's nothing I love more than professional basketball teams trading troubled baggage.
Remember 2009 ? when Raef LaFrentz's $13 million expiring contract was the most valuable asset on the market? That's the kind of world I want to live in all the time.
Dealings have been slow thus far, with only the Houston Rockets, Sacramento Kings and Phoenix Suns getting together to (in order) acquire the No. 5 selection in last year's draft, shed some salary and reunite the Philly-born Morris twins for the price of a second-round pick.
And so, with mere hours to go, which of your Philadelphia 76ers is on the trade block? Kind of the whole team aside from Jrue Holiday. Grantland's Chris Ryan wants to restart the Andre Iguodala era with this fictional offer for Danny Granger.
Then again, no one would be surprised if the Sixers held steady until 3 p.m. As of last night, the team's phones were "pretty quiet."? As Adrian Wojnarowski just put it:
Either way, just for fun, here are five potential candidates to get shipped:
Nick Young: Swaggy is on a one-year, $6 million deal and has seemingly matured enough under Doug Collins that a team in need of scoring depth could want him to play for his fourth team in the last two seasons.Really, unless they're called with something tempting, the Sixers are probably better off holding onto their own EC's to generate their own cap space.Dorell Wright: A similar circumstance. Dorell's $4 million comes off the books this summer and he's been less and less a factor for the Sixers as the season has gone on. Wright remains highly versatile and its unclear as to why he falls in and out of favor with head coach Doug Collins, but he's certainly not the first to have that happen. Wright is a cheap enough option with upside for the next few months.
Spencer Hawes: Teams are always in need of functional bigs, and Hawes is wrapped up in a neat little two-year deal that will pay him $6.5 million this year and next. Hawes isn't anyone's savior, but he's young and he's shown enough in flashes to entice some playoff-bound teams in need of short-term, cost-effective help in their frontcourt.
Royal Ivey/Damian Wilkins: Expiring throw-ins.
The elephant in the room here is obviously Andrew Bynum, but his fate will be decided this summer and not this afternoon. The most likely scenario remains the Sixers staying put, continuing to wait for Bynum, and hoping they learn something from watching him play with this roster for a even a handful of games.
If the Sixers don't do anything today, they'll have almost $29 million (including Bynum) coming off the books this summer.
That sounds like good news, but here's the real question: Do you trust the Sixers, assuming they do not reach a new agreement with Bynum, with that kind of cap space?
