Unexpected diagnosis: Some medical tests may be harmful to your health

Everyone’s heard a story: Someone got an MRI for a sports injury or dizziness and the radiologist found a tumor, just in the nick of time. Or maybe it was an aneurysm, just about to burst. Lives were saved. It was great luck.

Some of the stories are dramatic. Joan Rachlin of Boston got what seemed to be a routine Pap smear 27 years ago. Like most Pap smears, it was deemed normal. “I got a call something like seven months later from a gynecological pathologist at Brigham and Women’s Hospital in Boston,” Rachlin told NBC News.

“He was doing research on Pap smear tissue and he had come across mine. He discovered that my Pap smear had been misread and that, in fact, I had a cancerous lesion.”

It’s what’s called an incidental finding — the researcher, who Rachlin says does not wish to be named, was studying something else and in fact had to go to some trouble to match the sample to a real person. “He thought my Pap smear had really been so poorly interpreted that my life was in danger,” said Rachlin, who is executive director of Public Responsibility in Medicine and Research. “I am alive today because a very, very conscientious researcher had read my Pap and decided to break the code and find me.”

Joan Rachlin found out she had cancer 27 years ago, purely by accident. There were no guidelines at the time for telling her.

Joan Rachlin found out she had cancer 27 years ago, purely by accident. There were no guidelines at the time for telling her.
There were no guidelines — the researcher just went rogue. More checks showed Rachlin did indeed have cancer, but it was early stage and surgery took care of it.

Today whole industries are building up around the possibility that a test will find a medical problem that was just about to kill you. The latest entry — whole genome tests that promise to detail your medical future in a drop of spit.

But it’s starting to become clear that not all these findings are lifesaving, and some can be downright harmful. Take the case of the elderly woman whose chest lung X-ray showed what looked like lung tumors. She had a biopsy done — a tricky procedure that involves poking a long needle through the chest wall, or sending a bronchoscope down into the delicate lungs. Her lung collapsed and she died. The tumor, it turned out, was harmless. Were it not for the scan, she would have still been alive.

Her case is outlined in a report issued last month by the Presidential Commission for the Study of Bioethical Issues.

As more and more tests become available and standard, from MRIs to CT scans, to genetic tests and ultrasounds, these issues will come up more often. There’s even a name for these often harmless tumors that get discovered — they’re called incidentalomas.

For instance, 10 percent of brain scans and more than 30 percent of abdominal CT scans turn up something that doctors weren’t looking for and that may need more tests, says Dr. Stephen Hauser, who heads the neurology department at the University of California, San Francisco and who helped lead the Bioethics Commission panel in its report on the issue.

Parents’ attitude linked to kids’ chronic pain

Adolescents whose parents suffer from chronic pain may be more likely to develop ongoing pain too – especially if the parent tends to ‘catastrophize’ pain, according to new research.

“Children are careful observers of everything that we do as parents, and how we respond to our pain and to their pain is no different,” said Anna Wilson, a psychologist at Oregon Health & Science University who led the study.

Sometimes acting worried or repeatedly asking how a child is feeling can lead them to worry that the problem they are having is serious, even if it isn’t, Wilson said.

“Unfortunately, we know from many research studies that this (misplaced) worry tends to make pain worse,” she told Reuters Health.

In the study, 178 kids between the ages of 11 and 14 were recruited through their schools. They filled out questionnaires asking about ongoing physical issues such as backaches, stomach pain and headaches, as well as how much the pain interfered with their everyday lives. The adolescents’ parents answered similar questions about their own pain.

Both kids and parents also filled out surveys focused on how they coped with the child’s pain, such as whether parent or child felt helpless about the condition or blew the pain out of proportion.

About one-fourth of adolescents and two-thirds of parents in the study reported having chronic pain, and parental pain was significantly linked to the likelihood of that parent’s child having pain.

Having a parent with pain and having a parent who magnified the significance of pain boosted the risk that a child would also put more emphasis on the pain’s importance, the team reports in the Journal of Pediatric Psychology.

The take-home point, according to Wilson, is that the most helpful way to approach ongoing pain in a child – such as repeated headaches or muscle aches – probably differs from the way a parent might act when the child has a short-term illness like stomach flu or a sprained ankle.

For that reason, it can be helpful for parents with chronic pain to seek outside help to pinpoint their own strengths, and to assist their kids in developing healthy ways to cope with pain and discomfort.

“Being a parent is hard; pain just makes it harder,” Wilson said.

“If you are a parent who has chronic pain and you are worried about how it might be impacting your child, talk with your own doctor, a pain psychologist or your child’s doctor,” she said.

Mediterranean diet linked to lower risk of Type 2 diabetes

Even without weight loss, adhering to a diet rich in fresh produce, chicken, fish and olive oil is 40% more effective in heading off the development of Type 2 diabetes than following a low-fat diet, a new study has found.

The research suggests that for the nation’s 78 million obese adults, a diet that minimizes red meat and sweets but incorporates plant-based fats may be a sustainable way to improve health — even if permanent weight reduction proves elusive.

The findings add to mounting research that suggests a traditional Mediterranean diet may be easier to adhere to and more likely to improve health than more restrictive regimens.
Compared with those on a low-fat diet, trial participants whose Mediterranean-style diet was supplemented with a daily dose of tree nuts — almonds, walnuts and hazelnuts — were 18% less likely to develop Type 2 diabetes. The researchers called that a positive trend but acknowledged that the difference fell short of demonstrating beyond doubt the superiority of such a diet over a standard low-fat diet.

Published Monday in the Annals of Internal Medicine, the latest entry in the diet fray followed for more than four years a group of 3,541 older Spaniards who were at high risk of developing cardiovascular disease. They were a subgroup of a larger clinical trial that demonstrated the effectiveness of the Mediterranean diet in reducing the risk of heart attacks and strokes.

Anti-smoking efforts have saved 8 million American lives

Anti-tobacco efforts have saved 8 million lives in the 50 years since the publication of a landmark Surgeon General report, “Smoking and Health,” a new analysis shows.

The 1964 report, which concluded that tobacco causes lung cancer, led to a sea change in American attitudes toward smoking. Smoking rates have plunged 59% since then, falling from 42% of adults in 1964 to 18% in 2012, according to the Centers for Disease Control and Prevention.

By avoiding tobacco or quitting the habit, people have gained nearly two decades of life, according to the analysis, published Tuesday in the Journal of the American Medical Association.

An American man’s life expectancy at age 40 has increased by an average of nearly eight years, and a woman’s by nearly 5½ years, since 1964. About one-third of those gains come from decreased tobacco use, the analysis says.

“Tobacco control has been described, accurately, as one of the great public health successes of the 20th century,” CDC director Thomas Frieden writes in an accompanying editorial.

Twenty-six states and Washington, D.C., now ban smoking in indoor public places. As smoking rates have declined, so have the incidence rates of many cancers. About 40% of the decline in men’s overall cancer death rates, in fact, is due to the drop in tobacco use, according to the American Cancer Society.

Tobacco damages virtually every part of the body, Frieden says, causing one-third of heart attacks. Smoking increases the risk of 14 kinds of cancer, including acute myeloid leukemia and tumors of the mouth, esophagus, stomach and pancreas, according to the American Cancer Society. About 443,000 Americans die from smoking-related illnesses every year.

Nearly 18 million Americans have died from tobacco just since the Surgeon General report was published, according to the new analysis, led by Theodore Holford of the Yale University School of Public Health.

Tobacco killed 100 million people worldwide in the 20th century, according to the Campaign for Tobacco-Free Kids. If current trends continue, tobacco will kill an additional 1 billion in the 21st century, the group estimates.

Frieden notes that smoking remains a major health challenge. Nearly one-third of non-smokers are still exposed to secondhand smoke, either at home or at work. Images of smoking are still common on TV and in movies. Tobacco taxes are too low in many parts of the country, making cigarettes affordable for both adults and kids. And although most smokers say they want to quit, few of them receive proven treatment, such as counseling and medication, which together can double their odds of kicking the habit, he writes.

A spokesman for R.J. Reynolds Tobacco Company declined to comment.

David Sylvia, a spokesman for Altria, the parent company of tobacco giant Philip Morris USA, says his company’s goal today is simply to make current smokers aware of its brands, and it has no interest in attracting new smokers.

“Adults should have the ability to choose to purchase a legal product,” Sylvia says. “We want to make sure that when adult, current smokers are choosing their brand, they think about our brand.”

Hepatitis E Outbreak in Uganda

Health Minister Christine Ondoa has expressed concern over the rising prevalence of Hepatitis B in eastern Uganda, despite efforts to contain the deadly disease.

“Ministry and district health officers are working tirelessly to see that we solve this problem; we call upon all people to embrace preventive measures because it is better than cure,” Ondoa said in Soroti last week,

Like HIV, Hepatitis B spreads through sex, mother-to-child transmission, sharing of sharp objects and blood transfusion. But it is 15 times more infectious than HIV/Aids.

The disease is incurable and difficult to detect, and causes liver cancer and chronic liver failure.

“The government has already introduced medicine for children below one year,” Ondoa said, as the government launched a programme to distribute 21 million nets. “This is the vaccine they get below the left thigh when they are six weeks; parents immunize your children against Hepatitis B.”

Hepatitis B virus infection is highly endemic in Uganda, with transmission occurring in childhood and adulthood. Some 1.4 million adults are chronically infected and some communities disproportionately affected.

New lung cancer screening guidelines approved for older smokers

Guidelines recommending annual low-dose CT lung cancer screening for older smokers have been approved by the US Preventive Services Task Force. The recommendations apply to individuals aged between 55 and 80 who are at high risk for lung cancer as a result of heavy smoking.

The guidelines are published in the journal Annals of Internal Medicine.

According to the American Cancer Society, approximately 228,190 new cases of lung cancer will have been diagnosed during 2013, with 159,480 deaths from the disease. This accounts for around 27% of all cancer deaths.

Background information from the guidelines states that around 85% of all cases of lung cancer are caused by smoking, and the risk of lung cancer increases with age, particularly for those aged over 55.

Dr. Michael LeFevre, co-vice chair of the US Preventive Services Task Force (USPSTF), says these factors suggest that the longer a person smokes, the higher their risk is for developing lung cancer.

Dr. Michael LeFevre, co-vice chair of the US Preventive Services Task Force (USPSTF), says these factors suggest that the longer a person smokes, the higher their risk is for developing lung cancer.

He adds:

“When clinicians are determining who would most benefit from screening, they need to look at a person’s age, overall health, how much the person has smoked, and whether the person is still smoking or how many years it has been since the person quit.”

Low-dose CT scanning ‘more accurate’
The 2004 lung cancer screening recommendation from the USPSTF stated that the “evidence was insufficient to recommend for or against screening for lung cancer in asymptomatic persons with LDCT (low-dose computed tomography), chest radiography, sputum cytologic evaluation or a combination of these tests.”

With the aim of updating these recommendations, a panel from the USPSTF reviewed more than 33 studies involving current or former smokers who were at average or high risk for developing lung cancer.

The analysis included a study of more than 50,000 people who were a part of the National Lung Screening Trial.

From their research, the panel found that low-dose computed tomography (CT) lung cancer screening was more accurate in identifying the disease in its early stages, compared with alternative screening tests.

Their findings have led the USPSTF to “recommend annual screening for lung cancer with low-dose computed tomography in adults aged 55 to 80 years who have a 30 pack-year smoking history and currently smoke or have quit within the past 15 years.”

A 30-pack year is the equivalent to one pack a day for 30 years, or two packs a day for 15 years.

Screening not recommended when smoking ceased for 15 years
However, they note that screening should be stopped once a person has not smoked for 15 years or develops a health problem that shortens life expectancy or the willingness or ability to undergo potential lung surgery.

Dr. Virginia Moyer, chair of USPSTF emphasizes that it is important to assess a patient’s overall health to determine whether screening is appropriate.

“The benefit of screening may be significantly less in people with serious medical problems and there is no benefit in screening someone for whom treatment is not an option,” she says.

“In these people, screening may lead to unintended harms such as unnecessary tests and invasive procedures.”

She also adds that although screening for lung cancer is beneficial, it should not be seen as an alternative to giving up smoking.

Kidney stones: this pain is ‘Worse than childbirth’

One of the most common presentations is the flank pain on one side. It sometimes radiates down into the stomach, and it can actually radiate down into the genital area. That type of pain is pretty commonly seen in stone patients.

Sometimes there’s nausea and vomiting. Those type of symptoms are something that gives us a clue that this may be a stone.

The CAT scan is the gold standard for imaging for kidney stones. That’s usually the way to diagnose it. You can’t do it from a blood test or anything else.

Why do people say that they are so painful?
It blocks the flow of urine in the kidney, and it causes backup. And it’s an excruciating pain. A lot of people do describe it as worse than childbirth.

When the system is trying to push urine out, what happens is: your kidney and your ureter — they have this muscle propagation that goes down the kidney into the ureter — when it’s trying to push and the stone is blocking it, you get these intense pains. That’s why we call it colicky, it comes and goes and it’s extremely painful and the main reason for the pain is the backup of urine.

What’s happening exactly?
Usually, if they have two kidneys, they urinate fine, because you’re getting urine on the other side. The problem is, that kidney is producing urine but it can’t get pushed down.

If you take a pipe and you clog it off and somehow you’re still getting fluid into the other end … if it’s a pipe that can expand, it starts expanding.

The backup is like that. It causes a great deal of pain because you’re expanding your system. You don’t have any pop-off valve. Once it starts expanding, it’s expanding unnaturally.

It’s called hydronephrosis, and it’s basically backup of urine into the kidney.
What to do for kidney stones

Are there particular risk factors?
There are certain diseases associated with kidney stones, things like hypoparathyroidism, or some bowel diseases where your absorption isn’t normal.

Things like obesity and diabetes are associated with kidney stones. The main dietary factors are low water intake and high salt intake and animal protein — anything you killed to eat. If you have high amounts of those intakes, it causes your urine to acidify and then it becomes more prone to having stones.

It just depends on the person. If you have a family history, you’re more apt to get a stone.

What is the treatment?
If the stones are small enough, they usually pass on their own. Sometimes it can be an uneventful passage, or sometimes it’s just an excruciating passage, but we can help them out with pain medicine and some other medicines.
We say greater than 5 mm we start watching them closely. They have a higher chance of requiring surgery to pass the stone.
So it’s possible that with pain medicine, it could go away on its own?

Yep, they can pass it. As long as it’s small enough, and there’s nothing abnormal in their system that prevents it from moving through, if it’s small enough people can pass the stones by themselves.

How long does that take?
It can take a few days. Depending on where the stone is and how small it is. Sometimes we monitor up to six weeks, but if the stone isn’t progressing, we’ll go ahead and take care of it.

If the pain is so much that they can’t endure it, then we will go ahead and treat. If their pain is coming and going, and well-controlled with things like ibuprofen or other pain medicine, sometimes we just wait and let them try and pass it.

Sales of diet sodas are going flat

After surging in popularity for decades, diet sodas are beginning to lose their fizz.

Concerns over chemicals they contain as well as doubts that they actually aid in weight loss are giving drinkers a new taste for water.

At the Mid City Gym in Manhattan, Ben Roman is closing in on his fourth mile on the treadmill. And he’s ready for a drink, but not the kind he used to crave.

“I don’t drink soda at all now. More water now,” Roman says.

“I advise people should really start drinking water, and if possible, good-quality water, filtered water.”

More than ever before, plain old H2O is muscling in on the $61 billion-a-year soda industry.

Over the past year, sales of non-diet sodas have declined 2.2 percent, while diet sodas have declined 6.8 percent.

“There has been a negative attitude about artificial sweeteners in this country that has been growing over the years. It’s not all of a sudden,” says Harry Balzer, who analyzes eating trends for the NPD Group, a global market research company.

To stop the sliding sales, the beverage industry is looking at replacing artificial sweeteners such as aspartame and saccharine with those derived naturally from the stevia plant.

“Twenty years ago, it was all about avoiding harmful substances, avoiding calories, avoiding sugar, avoiding fat, avoiding cholesterol,” Balzer says. “This generation looks at health as, ‘What can you add to my diet? Where is the whole grains, where are the antioxidants, where is the dietary fiber?’ ”

Natural foods in general have increased in popularity. Ten years ago, diet and non-diet soft drinks were the second most popular food item. Today, they’ve fallen to fourth place, behind sandwiches, fruit and vegetables.

Back at the gym, Andre Giulino drinks a toast to that trend every day. His company is about to launch a new bottle design – for water.

cancer fighting nanorobot may be able to target tumors

Could nanorobots be the next big cancer-fighting tool? Researchers from Chonnam National University in Gwangju, South Korea have created so-called “Bacteriobot,” a genetically-modified non-toxic salmonella bacteria that delivers cancer treatments that target tumors.

The bacteria is attracted to chemicals released by cancer cells. The Bacteriobot then goes directly to the tumors and releases the medication stored inside, attacking the problem areas. Traditional cancer treatments often wreak havoc on healthy tissues and other internal organs, so any treatment that can target just the tumors while sparing other tissue is highly sought after.

“First of all, the main feature of Bacteriobot is that the robot has a sensing function to diagnose the cancer, and it’s attacking the cancer itself as it uses the bacteria’s brain while moving toward the tumor region with its flagella,” Park Jong-Oh, director of robot research initiative at Chonnam National University, told Reuters.

Nanorobots in medicine isn’t an entirely new approach. CNET reported that Duke researchers were able to create a nanorobot called a “DNA nanocage” that could hold and release a biomolecule as well.

5 Natural Beauty Cheats You’ve Probably Never Heard Of.

Whiten Teeth With Activated Charcoal

It seems counter-intuitive that activated charcoal – a black substance that stains everything – would help to whiten teeth, but it really is very effective.

Simply dip a wet toothbrush in some activated charcoal and brush for two minutes before rinsing the mouth with water. The activated charcoal will pull toxins out of the teeth and remove stains.

Treat Acne & Other Skin Conditions With Banana Peels

This is a great little trick for treating acne, warts, stopping the itch from bug bites and poison ivy and reducing the appearance of fine lines and wrinkles with an ingredient you’d normally throw in the trash.

Simply rubbing the inside of a banana peel on your face helps all of the above. Banana peels are rich in antioxidants, vitamins and nutrients which are absorbed into the skin.

Reduce Wrinkles, Cellulite & Stretch Marks With Gelatin

According to Mommypotamus.com, eating gelatin increases collagen production which are the building blocks of the skin.

A diet high in gelatin helps to:

Reduce wrinkles
Reduce cellulite
Reduce stretch marks
Grow strong hair and nails
Balance hormones

Naturally Conceal Gray Hair With A Herbal Hair Rinse

Some women look to conceal their gray hair using chemical dyes and other harmful products – instead try this homemade sage and rosemary hair rinse and gradually cover gray hair naturally.

Bring one cup of water to the boil, remove from the heat and add a quarter of a cup of dried rosemary and a quarter of a cup of dried sage. Allow to steep for 30 minutes. Using a coffee filter, strain the mixture so you are left only with the infused herbal water.

To Use: Position your head over a bowl and rinse the liquid through a number of times, massaging it all through the hair.

Gradually gray hair will fade and the natural color will return. Many report seeing noticeable differences after just one month.

Use Rosehip Seed Oil

“A study at the University of Santiago in 1983 was the first significant research to reveal the incredible anti-aging properties of rosehip seed oil. 180 individuals with deep wrinkles, premature aging, UV damage, facial scarring, acne and other skin related problems were treated using rosehip seed oil. The results showed that the treatment helped to regenerate the skin, reduce scars and wrinkles and help skin to regain its natural color and tone.”
