You may have heard about the study “Bone Density Testing Interval and Transition to Osteoporosis in Older Women” (Gourlay et. al., NEJM, Jan 19, 2012) which analyzed post-menopausal women enrolled in SOF (Study of Osteoporotic Fractures). This study concluded that estimated BMD testing intervals can be as long as 17 years for those with normal BMD or “mild osteopenia” (defined in this article as a T-score of less than -1.0 and greater than -1.5) and 5 years for “moderate osteopenia” (T-score of less than or equal to -1.5 and greater than -2.0). The article has generated a great deal of interest in the lay press and medical wire services.

Response to Canadian Task Force Recommendations…
To Our Patients,
You are probably aware of the LATEST controversy regarding screening mammography. At the end of the day, each patient is going to make a decision that she feels is the best for her. However, before you take the latest Canadian Task Force recommendations seriously and stop having regular mammograms, remember that if there is one thing we know about breast cancers (if not all cancers) it is that “BIG IS BAD”, “BIGGER IS WORSE” and “SMALL IS ALWAYS BETTER THAN BIG”!, and remember these FACTS that no amount of scientific scrutiny or statistical manipulation can refute.
ACR-SBI Statement on Mammography Radiation
Some Americans have expressed concern, due to an erroneous media report, that the small amount of radiation a patient receives from a mammogram may significantly increase the likelihood of developing thyroid cancer. This concern simply is not supported in scientific literature.
Subs for Seniors Fundraiser returns for its best year yet
When Mr. Sub owners Spiros and Dimos Vovos wanted to give back to their community, no one -not even the brothers – knew that their Subs for Seniors day would become an annual event that raises thousands of dollars for seniors at the local nursing home. In two years, thanks to the generosity of their sponsors and the support of their customers, the brothers have raised $7,800 for the residents’ Fund at Community Nursing Home Port Perry and the Vovos boys are hoping Wednesday, June 1, will be their best event yet.
“It just keeps getting bigger!” said Spiros, who now has 13 sponsors and more clamouring to get in on the fun. “We’re hoping to raise $5,000 this year.”
The Vovos brothers will donate one dollar for every 12-inch sub and fifty cents for every six-inch sub sold that day to the local nursing home to enrich the lives of seniors living there. The Vovos brothers will also hold a donation draw on June 10. A minimum $5 donation will get customers in on the draw for some fabulous prizes: a pair of Blue Jays tickets donated by Port Perry resident Steven Fox; a pair of Jays tickets for the June 12 game against Boston donated by Mr. Sub Port Perry, a Nescafe Dolce Gusto Coffee Machine donated by Krups, a Broadstone six-man dome tent donated by Canadian Tire Port Perry and a Sony Blue Ray Player donated by Mr. Sub Port Perry.
Just some of the events that residents were able to enjoy last year thanks to the Subs for Seniors donation include visits from Zoo to You and the Super Dogs, a trip to WindReach Farm, a spin with the Blue Nights Motorcycle Derby, a carnival fun fair with Bellybutton the Clown and an outdoor movie night in the parking lot featuring The Sound of Music.
According to program aid Brenda Carberry, monies raised through Subs for Seniors this year will pay for a field trip in August for 25 lucky residents to Eaglewood, wheelchair accessible lodge in Pefferlaw, complete with horses and pigs, fishing pond, campfire and an accessible tractor ride through the bush.
Residents journeyed to the lodge last year with some staying for the day and others bunking out for two nights.
“The residents wanted to go out for dinner so we took them to a fancy restaurant in Pefferlaw,” said Brenda and they loved sitting outdoors around the campfire roasting marshmallows and dipping them in Bailey’s Irish Cream! We even made the wish of one who has since passed away come true. He wanted get on a horse again and we got him riding.”
The money from Subs for Seniors allows the nursing home to offer more “community based programs,” said Program Director Leisa Saunders. “Sometimes our budgets don’t allow us to do what we really want to do with our residents and this fundraising helps to offset the costs so we can develop more programs for more people. We’ve had a big turnout to many of the events, with residents, families, staff and volunteers all coming out to enjoy the entertainment. Because it’s affordable we can take a much broader approach to our activity programming.”
And for Spiros, that’s what it’s all about.
“We’re helping to bring entertainment to seniors who can’t get out on their own to enjoy things anymore,” said Spiros, who was invited to the home for the Zoo to You event in July. “The sunroom was packed with residents and family members and children. It was priceless to see how excited and happy people were. The buzz in the building was electric.”
Thyroid Shields – CCO Response
Recent American media reports (e.g. Dr. Oz) have highlighted the use of thyroid shields/collars during
routine mammography as a means to minimize exposure to radiation during the procedure. This has
raised concerns amongst Ontario Breast Screening Program (OBSP) clients.
Research indicates that the risk of thyroid cancer due to medical diagnostic x-rays, if any, is very small.
Risk decreases markedly with age.
According to the OBSP Mammography Quality Control X-Ray Safety Policy and Procedures (2004): “X-ray
shielding devices are not required for patient protection; however, they can be used to allay fear of
The use of thyroid shields is not indicated for mammography. The dose to the thyroid from
mammography is negligible and there is no scientific reason to supply thyroid collars for this

The ‘Dr. Oz Show’ and thyroid shields: the saga continues…
What’s a woman to do? Should she believe one of the most trusted cardiologists in North America or expert radiologists specializing in breast imaging? You may have been left with such questions if you watched the “Dr. Oz Show” episode on thyroid shielding that aired April 14.
The program was dedicated to clarifying whether individuals should wear thyroid shields when having radiation-based procedures such as mammograms and dental x-rays. While radiology advocates believe the shields are unnecessary for mammography, women across the U.S. have been asking for the protection after an email went viral in March based on advice Dr. Mehmet Oz gave in a show that originally aired last year.
This week’s episode was ostensibly intended to set the record straight, with Oz, the cardiothoracic surgeon who hosts the show, inviting experts from dentistry and radiology to comment on the email controversy and the pros and cons of thyroid shielding. But a combative Oz defended his original advice, and ultimately turned the show into a lecture for health professionals on the necessity of listening to their patients.
Rising thyroid cancer rate
The backstory for the controversy is the rising incidence of thyroid cancer, which has increased fourfold since the 1970s. The original episode in 2010 said that some of the increase could be due to radiation exposure from dental x-rays and mammograms, and advised the use of thyroid shields to reduce risk — advice that prompted statements of opposition from imaging organizations.
Appearing on this week’s show to represent healthcare professionals were luminaries from radiology and dentistry, including the following:
Dr. Daniel Kopans, director of breast imaging at Massachusetts General Hospital
Dr. Phil Evans, director of the University of Texas Southwestern Center for Breast Care
Dr. Jocelyn Rapelyea, associate director of breast imaging at the Breast Imaging and Intervention Center of George Washington University
The show exuded the atmosphere of a pep rally, with Oz pointing out that many doctors did not agree with his recommendation for women to wear a thyroid shield when having a mammogram. “I’m taking on my critics,” he stated emphatically, and from that point on he barely let the invited radiologists get an informative word in edgewise.
“My warnings sparked a firestorm,” Oz said. “You turned the medical community upside down by demanding thyroid guards while getting x-rays. I want you to have the power. It’s about your right to control your care.”
The invited guests pointed out the impracticality of Oz’s advice, indicating that the radiation dose exposure to the thyroid gland after 40 years of annual mammograms would be less than the background radiation received by sitting in a television studio for 60 minutes.
In addition, using thyroid shielding could affect the diagnostic quality of a mammogram, and images might be compromised altogether, requiring a retake and doubling the amount of radiation exposure to the breast.

The image on the left is a mediolateral oblique view demonstrating the thyroid shield obscuring the upper posterior breast along with a degraded image. The image on the right was repeated without the shield and shows normal breast tissue. All images courtesy of Dr. Phil Evans.
When Kopans commented to Oz that “if you are going to promote thyroid shields for mammograms, your audience should be wearing them now” to protect the thyroid gland from normal background radiation levels that cumulatively are much greater, Oz interrupted him. Oz stated that the protection was for a dose that a thyroid gland was receiving in one second rather than spread over 30 minutes, and why not protect oneself during that one second?
Kopans’ comment that radiation dose was cumulative, and if Oz wanted his audience to protect their thyroids they should wear a thyroid shield 24 hours a day, was ignored by the television host and appeared to fly over the heads of his studio audience.
A technologist positioned for a mammogram with the thyroid shield in place. Part of the thyroid shield is underneath the compression paddle and would cause a portion of the breast to be obscured on the mammogram. Evans and Rapelyea both stressed that thyroid shields, however well intentioned, could compromise a mammogram and require that it be performed again. Evans showed examples of such images. Rapelyea explained that a patient’s body shape and mobility might prevent her from wearing a thyroid shield due to positioning requirements. She explained that in the past week, as patients at her center were demanding thyroid shields, approximately 20% of screening mammograms had to be repeated.
Oz acknowledged that this could be a problem, along with the concern raised by Evans that fear of radiation could scare many women away from having mammograms. He told his audience members to get their mammograms because they save lives, and to listen to breast imaging specialists if they say that for specific reasons an individual cannot wear a thyroid shield and have a successful mammogram.
But his concluding remarks to the television audience fit the tenor of the show:
“Mammography makes a ton of sense, but you have the right to ask for a thyroid guard,” he said. “This is only going to happen if you make it happen. If you don’t ask those tough questions, there isn’t going to be any change. But if you do ask them, you have the power to make us doctors adjust to you and customize your care.”
Nuclear Medicine Grand Opening

PORT PERRY — After a ribbon-cutting ceremony, Jason Truong, a nuclear medicine technologist, left, gave a demonstration of the new nuclear medicine camera, on February 15, with Mayor Chuck Mercier volunteering as a patient. The diagnostic camera is housed in Port Perry Imaging in the Medical Associates building on Old Simcoe Road. February 15, 2011
Port Perry Imaging to showcase modern medicine
Located in the basement of the Medical Associates of Port Perry building, Port Perry Imaging offers a wide range of services to the community, from X-rays and ultrasounds to mammograms and echocardiograms. However, perhaps the least understood, and most valuable, tools at the clinic’s disposal is its nuclear medicine services, says Dr. Al Ismail. ”Our focus is to fulfill unmet needs in the community and nuclear medicine is one of the pieces that was missing,” he said. Port Perry Imaging began offering nuclear medicine services in July, but there were a number of hurdles to overcome before the first patient could be seen, explained Dr. Ismail. It took nearly three years before the Scugog clinic could offer the service, with securing a licence from the Canadian Nuclear Safety Commission taking the bulk of the time, he noted. Other challenges, such as special room for radioisotopes, purchasing specialized equipment, and hiring a nuclear medicine technician, also had to be overcome. ”It’s quite a bit more than just a regular X-ray,” said Dr. Ismail. But the benefits to the community, and the physicians who care for them, were worth the work, he stressed. Nuclear medicine can be used in a variety of ways, from bone scans and diagnosing abnormalities in thyroids and infections to cardiac studies. A very small amount of radioactive materials are entered into the patient’s body, such as through an intravenous line, and they go directly to the organ or area of the body where there is a concern. From there, the materials are detected by special types of cameras that work with computers to provide precise pictures and details. In Port Perry, one main focus of the nuclear medicine services is cardiac patients. In those cases, a tracer — a special radioactive chemical that has an affinity for the heart — would make its way into a patient through an IV line. The clinic would then take pictures of a patient’s heart and ask them to return the following day. At that time, another tracer would be inserted and the patient would be asked to carry out a stress test, most commonly a series of exercises on a treadmill. That work would paint a before-and-after picture of a patient’s heart and help determine any problems, explained Dr. Farah Nasser-Sharif. She’s one of the supervising physicians at the nuclear lab and a full-time internist for Port Perry. ”Defects would show up in the area and it would tell us which vessel is narrowed and if the patient is at risk of a heart attack if it’s not fixed,” she said.As for concerns about radiation, Dr. Ismail stresses that patients absorb more radiation through a CT scan. And, when presented with all the options most patients are agreeable to the service, added Dr. Nasser-Sharif. “They’re open to it, they realize we wouldn’t order the test if we weren’t looking for something significant,” she said. “We’re not doing it because we like ordering tests — we’re doing it because we’re looking for evidence of a disease. Our patients are quite open and quite willing to do it.” Those looking to take advantage of the nuclear medicine services must have a referral from their family physician or specialist. Most patients can be accommodated in about a week’s time.
Port Perry Imaging, 462 Paxton St., is open Monday to Friday, from 8 a.m. to 5 p.m.
