Hands On Learning Solutions, a business in Gig Harbor, Washington, evaluates and treats children for learning disabilities and claims to identify the underlying causes and help eliminate the symptoms. Much of what they do is questionable, and at least one of their methods is clearly bogus. Their program is reminiscent of the Brain Balance program that I wrote about in 2010. I’ll describe one child’s encounter with Hands On Learning Solutions and let you decide for yourself whether it sounds like a legitimate, helpful service.
Billy (not his real name) is an 11-year-old boy who is in the fifth grade at a Catholic school. He didn’t learn to talk until age 3, but he got speech therapy and is currently doing well in school, with a GPA of 86%. On his last report card, the section on “Successful Learner” rated him above average on working cooperatively with others, and satisfactory in all other categories, such as organizational skills, using time well, listening attentively, following directions, and completing work on time. His mother took him to Hands On Learning Solutions on the recommendation of a friend. On the intake questionnaire she expressed concerns about his written/oral expression, organization, study skills, attention focus, and motivation/behavior. She did not check the boxes for concerns about reading, spelling, comprehension, letter reversals, graphomotor skills, math, memory, poor grades, or slow work. (more…)
NOTE: I get a lot of emails asking me whether treatment X is evidence-based or a scam. This one was different. Zachary Hoffman had done his homework and had already answered the question for himself (at least, as well as it could be answered with the existing published evidence). I asked him to write up his findings as a guest post for SBM. This is a great example of how a layman can figure things out for himself using little more than google-fu and critical thinking skills. I hope it will be an inspiration to others who may not have thought they were qualified to do what we do on SBM.
Recently a friend alerted me to something called “Whole-Body Cryotherapy” which has been making the rounds on Facebook and is being promoted by many athletes and celebrities. I had only heard of cryotherapy in the context of freezing off a wart, but I was about to find out there was so much more. She explained that subjecting your entire body to extreme cold (-200˚F!) for a few minutes a day was a virtual panacea, with weight-loss, tissue repair, and beauty treatments as the target market. My limited background in biology hadn’t quite prepared me for understanding why subjecting oneself to cold air could possibly help treat any illness.
For instance, up here in Boston, I ride my bike all winter long, and on a particularly cold day, after a 5 degree ride, no one has commented that I seem particularly trim, or that my face is looking unusually beautiful. Unfortunately, a few days ago while riding my bike, I took a spill and mushed my hand pretty good. However, the cold winter air hasn’t done much to alleviate that pain or stop my right hand from being twice the size of the left. In any case, it seemed to me that I’d have to give this a closer look before I made any comments.
A quick search on Google led me to a website, Cryohealthcare, Inc. The website is aesthetically pleasing and has plenty of information about how this treatment can transform your life. To top it off, there are lots of endorsements from professional teams and athletes. It appears that for about $65 a pop you can subject yourself to unfathomably low temperatures and enjoy a whole-body tingle when you step out (when I was younger I used to jump in the snow and then get into a hot tub, so I get the appeal). A quick scroll down and we see indications for injury recovery, pain mitigation, and athletic performance, among others, followed nicely by the FDA quack Miranda warning. (more…)
The statin hypothesis is that statins reduce cardiac risk more than can be explained by the reduction in LDL cholesterol. That hypothesis has been overturned by a new study.
The consensus of mainstream medicine is that a high blood level of LDL cholesterol is a major risk factor for cardiovascular disease and that lowering high levels can help with prevention and treatment. Statins have been proven effective for lowering cholesterol levels and for decreasing cardiovascular and all-cause mortality. I recently wrote about the new guidelines for statin therapy.
Currently half of American men between the ages of 65 and 74 are taking statins, and 71 percent of adults with heart disease and 54 percent of adults with high cholesterol take a cholesterol-lowering drug.
There is still a fringe group of a few maverick “cholesterol skeptics” who think lowering cholesterol is useless or counterproductive, but the evidence shows they are wrong.
You can lead a true believer to facts, but can you make him think?
I got an e-mail with a link to a video featuring “Dr.” Leonard Coldwell, a naturopath who has been characterized on RationalWiki as a scammer and all-round mountebank. Here are just a few examples of his claims in that video:
- Every cancer can be cured in 2-16 weeks.
- The second you are alkaline, the cancer already stops. A pH of 7.36 is ideal; 7.5 is best during the healing phase. [We are all alkaline. Normal pH is 7.35-7.45.]
- IV vitamin C makes tumors disappear in a couple of days.
- Very often table salt is 1/3 glass, 1/3 sand, and 1/3 salt. The glass and sand scratch the lining of the arteries, they bleed, and cholesterol is deposited there to stop the bleeding.
- Patients in burn units get 20-25 hard-boiled eggs a day because only cholesterol can rebuild healthy cells; 87% of a cell is built on cholesterol.
- Medical doctors have the shortest lifespan: 56. [Actually they live longer than average.]
My correspondent recognized that this video was dangerous charlatanism that could lead to harm for vulnerable patients. He called it a “train wreck, with fantasy piled upon idiocy.” His question was about the best way to convince someone that it was insane. He said, “If you could rely on someone to follow and understand basic information about the relevant claims, it would be a gimme. But to the casual disinterested observer, who can interpret the whole video as ‘Well, he just wants people to eat right,’ pointing out the individual bits of lunacy just looks like so much negativity.”
He asked, “How do I best represent what’s happening to someone who is either a) emotionally invested in this and/or b) casually approving of it? … I just want to be patient, not shout anyone down, not make anyone defensive, and then win. Very surprised I don’t already know how. But I feel like I don’t. What is the psychologically sophisticated approach to this?” (more…)
A chiropractor in Illinois named Jeff Winternheimer claims to have discovered an effective way to heal herniated discs by rehydrating them. He calls it Functional Disc Rehydration and he offers it through a network of four offices in the Chicago area called the Illinois Back Clinic. He has lots of testimonials and one sorry amateurish attempt at a scientific study that claimed to show 100% improvement; but there is no published evidence, no controlled observations, and no comparison of his methods with other methods.
Degenerative disc disease
Between the spinal vertebrae there are soft, jelly-like compressible discs that act as shock absorbers. They are “corralled” by a fibrous annulus. As we get older, the disc material loses water and becomes less flexible; the disc thins, and the space between the vertebrae narrows, so in old age we are not quite as tall as we once were. Cracks in the annulus develop with age or with trauma, allowing the disc material to bulge out or rupture. Herniated discs don’t necessarily cause pain; disc degeneration can be seen on MRI in 37% of asymptomatic people over the age of 60.
We’re all going to die, but we don’t like to think about it. I’ll reach the proverbial threescore years and ten next month, so I’ve been thinking more about it, wishing I knew some reliable way to ensure that I would live many more years and remain fully functional until I suddenly collapsed like the Deacon’s wonderful one-hoss shay. There are myriad “longevity clinics” and “anti-aging” formulas, and every centenarian has an explanation that is the direct opposite of some other centenarian’s explanation. But what does the scientific evidence say? In his new book Spring Chicken: Stay Young Forever (Or Die Trying), Bill Gifford has done us a great service by investigating the latest scientific evidence about aging and presenting his findings in an engaging narrative form. He interviews some of the major players and introduces us to health fanatics who are convinced they can prolong their lives by doing things like monitoring their own blood cholesterol levels on a weekly basis, exercising obsessively, severely restricting their calorie intake, fasting intermittently, deliberately exposing themselves to stress like swimming in icy water, competing in extreme athletics, taking boatloads of hormones and supplements, experimenting on themselves with investigational drugs, and doing other questionable and sometimes bizarre things.
Are there limits to human life expectancy?
There is no documented case of anyone living longer than Jeanne Calment of France, who died at the age of 122. Jay Olshansky thinks biological forces limit how long we can live. Aubrey de Grey thinks some people alive today will live to be a thousand years old. Gifford explains the controversy and the reasoning behind both sides. Will we someday be able to re-engineer human biology to overcome the limits? The jury is still out. (more…)
In the news: a woman in Fort Wayne, Indiana is suing the Arbonne International company in Allen Superior Court, claiming that its product contained toxic levels of green tea extracts, causing her to develop acute liver failure.
Green tea accounts for 20% of tea consumption worldwide. It has become more and more popular because of its many reported health benefits; the consumption of green tea in the US has risen by 40% just since 2000. A less-processed form of tea, green tea contains higher levels of antioxidants and polyphenols than other teas. It was traditionally used to control bleeding, heal wounds, aid digestion, improve heart and mental health and regulate body temperature. More recently, research has suggested that it has many health benefits.
The evidence for health benefits
The University of Maryland Medical Center has a helpful webpage that summarizes all the relevant research and provides a long list of references. Green tea may reduce the risk of heart disease (but the FDA prohibits that claim on labels; they concluded there was no credible evidence to support it). Green tea lowers total cholesterol and raises HDL. Population studies suggest that it may help protect against several kinds of cancer, but the evidence is mixed: other studies suggest that it may actually increase the risk of some cancers, and it may interfere with cancer chemotherapy. It may help in inflammatory bowel disease, diabetes, liver disease, and weight loss. There is even preliminary evidence that it might prevent dental cavities, might be useful in arthritis, might help treat genital warts, and might even prevent symptoms of colds and flu. Studies show that drinking green tea is associated with reduced risk of dying from any cause. At first glance, it might sound like a panacea, but the evidence is still questionable. Much of it is from small, preliminary studies that have not been replicated or that contradict each other. (more…)
Ron Rosedale, MD has devised a “powerful program based on the new science of leptin.” “Finally — the ultimate diet for fast, safe weight loss, lifelong health, and longer life…” He suggests it will prevent or improve high blood pressure, diabetes, heart disease, osteoporosis, arthritis, and a host of other ills. He repeats the CAM canard that “doctors only treat symptoms” and claims that his diet corrects the underlying cause of obesity, premature aging, and many diseases. That underlying cause is hormone (leptin) dysfunction. His is essentially just another low carb diet, only with more fat and less protein than other versions. His recommendations are ridiculously elaborate and are not supported by good evidence. His diet extrapolates from basic science, is based on speculative hypotheses, and has never been tested to see whether it works and is safe, much less whether it is superior to other diets.
If this sounds vaguely familiar, it should. He is doing what so many proponents of fad diets have done in the past, and he does it poorly. His book is a puerile effort compared to Gary Taubes‘ Good Calories, Bad Calories; Taubes at least marshaled an impressive mass of scientific data, presented a cogent argument, and ultimately acknowledged that more studies would be needed to test his recommendations.

Flowers of the bloodroot plant, Sanguinaria canadensis. You’re welcome, I could have used a very different image (warning: gross bordering on horrifying; click on image to see it).
Cervical dysplasia is a precancerous condition picked up by Pap smears. It is most often caused by human papillomavirus (HPV) infection. Mild cases may resolve spontaneously and can be followed by observation with frequent Pap smears, but cervical dysplasia can progress to cancer. The standard treatment is to remove the abnormal cells with a cone biopsy (using a knife) or a Loop Electrosurgical Excision Procedure (LEEP) using a wire loop heated by electricity. Those procedures not only treat the disease, but they provide a pathology specimen that can be examined to rule out more serious or invasive disease. Both LEEP and cone biopsy are 85-90% effective in removing all the abnormal cells. If cancer is suspected, a cone biopsy is preferable because LEEP may damage the edges of the specimen and make it more difficult to interpret. Otherwise, LEEP is often preferred because it is less expensive and doesn’t require anesthesia or an operating room. I have discussed misguided attempts by alternative medicine practitioners to treat cervical dysplasia before.
Surgery is often perceived as scary and not “natural,” so it’s not surprising that a “natural” treatment has been devised to replace surgery. Escharotics are corrosive salves that get their name from the thick dry scab that they can produce called an eschar. The “natural” escharotic treatment alternative for cervical dysplasia involves applying a solution of bloodroot (Sanguinaria canadensis) and zinc chloride. They claim that the solution selectively kills abnormal cells of the cervix while leaving healthy cells unaffected. That claim is almost certainly false, and the efficacy and safety of escharotic treatment has not been properly tested or compared to conventional treatment. (more…)
