ongue piercing can lead to a damaging habit that causes a gap to appear between the upper front teeth, which could cost thousands of dollars to fix, a case study suggests.

The patient was a 26-year-old woman who came to the University at Buffalo School of Dental Medicine’s orthodontic clinic because a large space had developed between her upper front teeth. She also had a tongue piercing that held a barbell-shaped stud.

The woman did not have a gap in her teeth before she had her tongue pierced seven years before. But she developed a habit in which she repeatedly pushed the stud against her upper front teeth, which created the gap, the study authors noted.

“The barbell is never removed because the tongue is so vascular that leaving the stud out can result in healing of the opening in the tongue, so it makes perfect sense that constant pushing of the stud against the teeth — every day with no break — will move them or drive them apart,” study author Sawsan Tabbaa, an assistant professor of orthodontics, said in a university news release.

The woman was treated with braces to close the gap between her front teeth, according to the case study published in the July issue of the Journal of Clinical Orthodontics.

Tabbaa noted that tongue piercing can also cause chipped and fractured teeth, gum trauma, infection, hemorrhage and even brain abscess.

“The best way to protect your health, your teeth and your money is to avoid tongue piercing,” Tabbaa said.

Paging script-writers: Pumping on a patient’s chest during CPR while a stretcher careens down a hospital hallway works just fine, Chinese researchers have found.

By straddling patients on the stretcher — think “ER,” the American TV drama — paramedics can get them faster to and from the ambulance while still doing cardiopulmonary resuscitation (CPR).

What hadn’t been clear was how that precarious position would affect the quality of chest compression done by people without the balance of a bull rider.

So the researchers, led by Dr. Zhou Yaxiong at West China Hospital of Sichuan University in Chengdu, had 20 medical students do chest compressions on a resuscitation dummy that measured the quality of their work. They would do compressions for one minute, both on the floor and on a moving stretcher.

When the researchers examined the data from the dummy, they found no difference in compression rate, depth or efficacy between the two positions. However, the students were able to start CPR about seven seconds earlier when they didn’t have to mount the stretcher, and they said it was comfortable sitting on the floor.

In the report, the researchers thank the students for their “enthusiastic collaboration” and note that none of them fell off the stretcher.

In clinical terms: “Paramedics do not necessarily need to stop transporting the victims while external chest compression is in progress but can perform straddling external chest compression on a moving stretcher instead,” they write in the journal Resuscitation.

“By doing so, time for transporting victims to the emergency department to get advanced life support may be shortened.”

Dr. Dana Edelson, associate chair of the CPR Committee at the University of Chicago, said the results were surprising.

“It goes against conventional wisdom that moving on a stretcher you would do CPR of the same quality as when you are on the floor,” she told Reuters Health, adding that more research was needed to confirm the findings.

She stressed that it wasn’t clear at this point that getting to the hospital sooner meant a better outcome. And the larger size of most Americans compared with Chinese might also make straddling patients a tougher job in the U.S.

“The general recommendation is still as far as possible to continue doing CPR at the scene and focus on doing the best CPR you can muster,” she said.

In case you were wondering: Doing CPR while walking alongside a moving stretcher, instead of straddling the patient, doesn’t work as well, according to previous studies.

It appears that mouth-to-mouth resuscitation - shown to be of limited value in another study last week - while straddling dummies on a moving stretcher has not yet been studied.

If you’re considering starting hormone treatments to ease the hot and bothersome symptoms of menopause, keep in mind that you could suffer even more if you ever stop the therapy, new research says.

The findings of the study, part of the large-scale Women’s Health Initiative (WHI), may give postmenopausal women pause before starting replacement of their body’s declining levels of estrogen.

“Evidence seems to suggest that 25 percent or more of women who start hormones might find it very difficult to stop them — ever,” study co-author Marcia Stefanick, a chair of the WHI’s executive committee, told Reuters Health by email.

Researchers randomly assigned more than 10,000 postmenopausal women who had undergone a hysterectomy - removal of the uterus — to take either estrogen therapy or a hormone-free placebo pill. All women then reported their symptoms before starting the therapy and again one year later.

A portion of the participants also filled out surveys before and after stopping the pills. One out of every three women noted troubling symptoms at the start of the study, with fewer complaints among older women.

After the first year, women on estrogen pills experienced about half as many hot flashes, 40 percent fewer night sweats and 20 percent less vaginal dryness compared to those taking the placebo.

However, the active therapy also led to significantly more breast tenderness, report the researchers in the journal Menopause.

Other problems appeared when the study ended. About 7 percent of women who did not report hot flashes before starting estrogen therapy experienced them after stopping about 7 years later, compared to less than 2 percent of women on the placebo.

The team also saw more joint pain and stiffness among estrogen users following the end of the study, whether or not the women had those symptoms when they enrolled.

The study is a companion to another WHI analysis, which concluded that a combination therapy of estrogen plus progestin could cause more harm than good in postmenopausal women who had not had a hysterectomy. After stopping therapy, five times as many women taking the hormones complained of menopausal symptoms compared to those assigned the placebo.

Further, hormone-treated women developed more breast cancers, and had more heart attacks and other events related to clogged arteries.

Based on that trial, doctors are now discouraged from prescribing hormone therapy only to prevent chronic diseases. The authors - one of 11 of whom reports having been funded by drug companies that make hormone replacement therapy — note that the new analysis adds support to the recommendation not to start hormone therapy for women without menopausal symptoms. The exception is the prevention of the bone-thinning disease osteoporosis.

Fortunately, as both WHI trials demonstrated, menopause symptoms usually subside on their own without the help of a pill. “The hot flashes would have stopped within 3 to 5 years for a substantial proportion of these women had they never started hormones in the first place,” said Stefanick.

Midriff-revealing uniforms are linked to a higher risk of eating disorders among college cheerleaders, new research shows.

Toni Torres-McGehee, an assistant professor of athletic training at the University of South Carolina, studied 136 college cheerleaders in Division I and Division II, trying to determine if there were links between their team positions, their clothing requirements (full or midriff uniforms, for example), body image and prevalence of eating disorders.

One-third of the cheerleaders appeared to be at risk of developing eating disorders, and those on teams with uniforms that bared the midriff were at highest risk. They were also most likely to have body-image issues.

“Maladaptive body image and eating behaviors can form during youth and last a lifetime,” Torres-McGehee said in a news release. “Teams and coaches should consider the long-term effects of requiring cheerleaders to wear revealing uniforms simply for aesthetic reasons.”

The study also found that the cheerleaders were most worried about failing to meet the expectations of their coaches regarding their bodies.

“The point of collegiate cheerleading is to create camaraderie and team spirit and to keep girls active and healthy,” Torres-McGehee said. “Cheer coaches should keep these ideals in mind and try to reinforce self-esteem among their team members.”

The findings were presented Wednesday at the annual meeting of the American College of Sports Medicine in Baltimore.

Medicines used to treat Parkinson’s disease may increase the risk of impulse control disorders, such as problem gambling, compulsive shopping and binge eating, researchers warn.

In a new study that included 3,090 patients being treated for Parkinson’s at 46 movement disorder centers in the United States and Canada, the researchers found that 13.6 percent of the patients had impulse control disorders. These impulse disorders included gambling (5 percent), compulsive sexual behavior (3.5 percent), compulsive shopping (5.7 percent) and binge eating (4.3 percent), and nearly 4 percent of the patients had two or more of these disorders.

Impulse control disorders were more common among patients taking dopamine agonist medications (17.1 percent) than in those not taking the drugs (6.9 percent), the study authors found. Other factors associated with impulse control disorders were: use of levodopa (another treatment for Parkinson’s); living in the United States; being younger or unmarried; smoking cigarettes; and having a family history of gambling problems.

“Dopamine agonist treatment in Parkinson’s disease is associated with 2- to 3.5-fold increased odds of having an impulse control disorder,” wrote Dr. Daniel Weintraub, of the University of Pennsylvania, Philadelphia, and Philadelphia VA Medical Center, and colleagues. “This association represents a drug class relationship across impulse control disorders. The association of other demographic and clinical variables with impulse control disorders suggests a complex relationship that requires additional investigation to optimize prevention and treatment strategies.”

The researchers noted that dopamine agonists are increasingly being used to treat other conditions, such as fibromyalgia and restless legs syndrome.

“Larger . . . studies in these other populations are needed to examine the possible relationships between dopamine agonist treatment, other clinical features and impulse control disorders,” the authors concluded.

The study is published in the May issue of the journal Archives of Neurology.

People who’ve had a stent implanted to keep a coronary artery open face an increased risk for heart complications and death if they have non-cardiac surgery in subsequent weeks, a new Scottish study has found.

“We looked at the risks connected to four and six weeks after surgery,” said study author Nicholas L.M. Cruden, a former cardiology lecturer at the University of Edinburgh and now a consultant for the National Health Service in Scotland. “Most of the risk was in the first six weeks. Between six weeks and one year, the risk was somewhat reduced, but still higher than expected.”

The study, published online May 4 in Circulation: Cardiovascular Interventions, found that 42 percent of people undergoing non-cardiac surgery within six weeks of stent implantation were more likely to have such complications as decreased blood flow to the heart and heart attacks or to die. These outcomes were found in just 13 percent of those whose surgery was done more than six weeks after stent implantation.

The risk of heart problems after non-cardiac surgery was even greater for the 65 percent of people whose stents were inserted because of a recent heart attack, compared with those had stable but chronic heart disease when they were given stents, the study found.

There are no formal British guidelines about surgery after stent implantation, Cruden said, but in France, he said, guidelines recommend that such surgery be postponed at least for a year.

Guidelines issued by the American Heart Association and other organizations in the United States recommend delaying surgery for at least a year after a stent implant, said Dr. Charles W. Hogue Jr., associate professor of anesthesiology at Johns Hopkins University School of Medicine.

The pros and cons of using clot-preventing drugs such as Plavix after stent implants have been debated for years, Hogue said. “The guidelines set antiplatelet therapy for a year or maybe indefinitely,” he said. “If you stop, you run the risk of stenosis [artery blockage]. But what happens if you have a tendency to bleed? That can cause all kinds of problems, particularly for the brain or the eye.”

Use of clot-preventing medication has to be decided patient by patient, Hogue said. “You have to judge risk vs. benefit on an individual basis,” he said. “This is a big public health issue because a lot of stents are being implanted.”

About 1.3 million artery-opening procedures are performed annually in the United States, Hogue said.

The Scottish study is the largest done to date on the effects of surgery after stent implants, Cruden said. The study shows a 50 percent increase in the risk for bleeding in such cases but no impact on surgical mortality, he said.

Poor people are more likely to die within five to 10 years after heart surgery than more affluent people, U.S. researchers report.

They followed 15,156 white men, 6,932 white women, 678 black men and 564 black women who had heart bypass or valve surgery between 1995 and 2005 and found that the poorest patients were 19 to 26 percent more likely to die within five years of surgery than the wealthiest patients, regardless of race or gender.

“We were surprised that consistently and pervasively, through every way of looking at the data, it turns out this isn’t about skin color or gender. It’s about being poor,” study author Colleen G. Koch, a cardiac anesthesiologist and vice chair for research and education in the department of cardiothoracic anesthesia at the Cleveland Clinic, said in a news release.

However, the researchers did find that poor patients were significantly more likely to be black and female.

Koch and colleagues also found that poorer patients had more atherosclerosis, serious cardiovascular disease, prior heart attacks, left ventricular dysfunction, heart failure, high blood pressure, prior stroke, peripheral artery disease, treated diabetes, and chronic obstructive pulmonary disease. They were also more likely to be smokers.

The study appears in the current issue of the journal Circulation: Cardiovascular Quality and Outcomes.

Poorer patients didn’t have a significantly higher death rate while in hospital immediately after surgery. Factors such as financial problems, educational barriers, and lack of referrals to cardiac rehabilitation programs may contribute to increased risk of death among poor patients in the years after heart surgery, Koch said.

Their survival rates might increase through improved access to primary prevention, earlier identification of risk factors, better access to long-term interventions, and enrollment in cardiac rehab programs, Koch said. Cardiac rehab typically includes monitored exercise, nutritional counseling, emotional support, and education.

Psychotherapy helps cut the incidence of psychological woes in patients with lupus who have high levels of daily stress, a new study finds.

The treatment also helps these patients improve and maintain their quality of life, according to a new Spanish study.

The research included 45 patients randomly assigned to a control group or to a therapy group. Each received 10 weekly sessions of cognitive behavioral therapy (CBT).

By the end of the study, the patients in the therapy group had significantly reduced levels of depression, anxiety and daily stress — along with significant improvement in quality of life — compared to those in the control group.

However, the patients in the therapy group didn’t show any significant reduction in lupus disease activity, said the Spanish researchers.

The study was led by N. Navarrete-Navarrete of the University Hospital Virgen de Las Nieves, and was recently published in the journal Psychotherapy and Psychosomatics.

Babies of women who take antidepressants during the latter part of pregnancy are slower in reaching some developmental milestones, new research shows.

Using data on more than 81,000 babies born in Denmark, researchers found that children whose mothers took antidepressants during the second or third trimester sat without support later and walked later than children of depressed mothers who did not take medication. This was especially true for boys.

Despite the delays, the children’s progress was still well within the bounds of normal development, the researchers noted. Children whose mothers took antidepressants sat about 16 days later and walked nearly a month later than the children of mothers who didn’t take the drugs.

According to the paper, researchers said they did not know if the changes were permanent or only temporary.

By 19 months, they found no differences in motor skills between kids exposed and not exposed to antidepressants.

But the 19-month-old children whose mothers had taken antidepressants were less able to occupy themselves for more than 15 minutes than toddlers whose mothers hadn’t taken antidepressants.

No other delays in any of the other 14 developmental milestones mothers were asked about, including language development, social development or other motor skills such as head control or rolling from back to belly, were noted among exposed children.

The study is published in the March issue of Pediatrics.

Despite some concerns, Dr. Diane Ashton, deputy medical director of the March of Dimes and an ob-gyn, urged women not to make any hasty decisions about discontinuing the drugs and to consult with their doctors first.

“For the most part, we feel it’s important for women to be adequately treated for depression during pregnancy,” Ashton said. “Depending on the severity of the symptoms, you may not have a choice. If the mother is depressed or suicidal to the point of hurting herself, she needs treatment.”

About 904 women in the study were depressed; of those, 415 women took antidepressants. Most took serotonin reuptake inhibitors (SSRIs), such as fluoxetine (Prozac), sertraline (Zoloft and Lustral), citalopram (Celexa) and paroxetine (Paxil). Some took an older class of drugs, tricyclic antidepressants or other types of antidepressants, including venlafaxine (Effexor). Some took more than one.

While the study isn’t the first to show that antidepressants may impact fetal development, it is among the first to look at the child’s development after birth, Ashton said.

A 2009 study in the British Medical Journal, also by the Danish researchers, found women who take certain antidepressants during the first three months of pregnancy were at a slightly increased risk of giving birth to babies with septal heart defects, or malformations in the wall separating the right side of the heart from the left. The risks were seen in sertraline and in citalopram.

Other research, however, about the risks of congenital abnormalities has been inconclusive.

So what should women do?

Discontinuing antidepressants is an option, but it has risks, especially if the mother’s depression is severe, said David Blackburn, a clinical psychologist and assistant professor of psychiatry and behavioral science at Scott & White Memorial Hospital in Temple, Texas.

Untreated depression may lead women to miss prenatal appointments, eat poorly — either too much or too little — and sleep poorly. Some people who are depressed also become socially isolated, or self-medicate with drugs or alcohol. Depression is also a risk for suicide or other self-destructive behaviors.

“Whether women continue with antidepressants has to be decided on an individual basis,” Blackburn said. “You have to weigh the risk of the depression with the slight risks of taking the antidepressants.”

In the United States, about one in five women have symptoms of depression while pregnant, according to the March of Dimes.

The U.S. Food and Drug Administration and the American College of Obstetricians and Gynecologists (ACOG) have issued warnings about an increased risk of heart defects associated with the use of the Paxil during pregnancy.

Blackburn urged women who don’t want to take medications during pregnancy not to try to go it alone and instead consider psychological counseling or support groups.
