Scientific studies are not meant to be amusing, but I laughed out loud when I heard about this one. After all the concern about possible adverse health effects from cell phone use, this study tells us cell phone use can prevent Alzheimer’s, treat Alzheimer’s, and even improve cognitive function in healthy users.
They studied transgenic mice programmed by their genes to develop Alzheimer’s-like cognitive impairment; they used a group of non-transgenic littermates as controls. For an hour twice daily over several months they exposed the entire mouse cage to EMF comparable to what is emitted by cell phones. They tested cognitive function with maze tests and other tasks that are thought to measure the same things as human tests of cognitive function. The authors claim to have found striking evidence for both protective and disease-reversing effects. (more…)
Faith healing is based on belief and is about as far as you can get from science-based medicine, but it is not exempt from science. If it really worked, science would be able to document its cures and would be the only reliable way to validate its effectiveness. Miraculous cures continue to be reported on a regular basis: what are we to make of them? In the Healing Rooms Ministry of Bethel Church in Redding, California, people regularly claim to be healed of cancer, broken bones, multiple sclerosis and many other ailments. Page after page of testimonials of cures are listed on their website. Are these cures real? If not, what is going on?
Amanda Winters, a journalist doing a series of articles on Bethel Church, interviewed me for a scientific view of these faith healings. She asked me some very incisive questions and understood my answers. She wrote what I thought was a balanced article, quoting me fairly and at more length than reporters usually allow.
Her article features a patient who believed his flat feet would be healed (bones would crack and form an arch). Healers poked him, blew a shofar at his feet, and covered him with a blanket when he collapsed on the floor. When he got up, his feet were unchanged. But
his faith was not shaken, he said, because he felt so loved and maybe the physical healing was secondary to the spiritual experience he had. (more…)
A correspondent wrote:
I hear all day long on my local radio station commercials for The Water Cure, which was created by a Dr. Batmangelli (I have no idea how to spell his name) promising wonderful cures by eliminating caffeine and alcohol and drinking water and sprinkling sea salt on your food. If you REALLY want to get cured even faster, swim in the ocean everyday.
That’s Dr. Fereydoon Batmanghelidj. His Big Idea was that dehydration is the main cause of disease. It was untenable to begin with, is supported by no evidence, was debunked on Quackwatch several years ago, and Dr. Batmanghelidj died in 2004, so I was surprised to hear it was still being vigorously promoted. But not very surprised. After all, homeopathy is still around.
The Water Cure is another in a long list of alleged miracle cures discovered by “lone geniuses” who are allegedly persecuted by a resistant medical establishment. These stories follow a pattern, and I think it is worthwhile looking at this prime example to understand something of the psychology of self-deception that is involved. (more…)
A recent story on NPR accused the drug manufacturer Merck of inventing a disease, osteopenia, in order to sell its drug Fosamax. It showed how the definition of what constitutes a disease evolves, and the role that drug companies can play in that evolution.
Osteoporosis is a reduction in bone mineral density that leads to fractures. The most serious are hip fractures, which require surgery, have complications like blood clots, and carry a high mortality. Many of those who survive never walk again. Vertebral fractures are common in the osteoporotic elderly and are responsible for dowager’s hump and loss of height. There is also an increased risk of wrist and rib fractures.
Bone density tends to decrease with age. Postmenopausal women are particularly susceptible to osteoporosis when their production of estrogen declines. The risk is increased in people taking corticosteroids and in people with certain diseases like rheumatoid arthritis. Other risk factors are European or Asian ancestry, smoking, excess alcohol, a family history of fractures, vitamin D deficiency, too much or too little exercise, malnutrition, and low body weight.
When a measurement like bone density varies widely in a population and decreases with age, how can we decide where to draw the line and call it abnormal? When does it become a disease requiring treatment? (more…)
The Graston Technique® is a modification of traditional hands-on soft tissue mobilization that uses specifically designed instruments to allow the therapist to introduce a controlled amount of microtrauma into an area of excessive scar and/or soft tissue fibrosis. The hope is that this will invoke an inflammatory response that will augment the healing process. It is also intended to reduce the stress on the therapist’s hands.
Microtrauma? Hurting people to make them better? I know sometimes an improperly healed bone must be re-broken so it can re-heal in proper alignment, but this is different. It bothers me that they are further injuring already damaged soft tissues and hoping (1) that the new injury will heal, (2) that that will help the older injury heal, and (3) that it can somehow avoid stimulating the deposition of just that much more scar tissue and fibrosis.
For instance, Graston is often recommended for a kind of knee tendonitis, IT band syndrome. Even if ilitobial band syndrome really is caused by fibrosis/adhesions — which is not a safe assumption — it seems like Graston technique might be just as likely to make it worse as better!
Graston seems to violate the “primum non nocere” principle. It is unpalatable. Of course that wouldn’t matter if the evidence showed it was effective. Does it? (more…)
Warning: If you are offended by humor that depends on psychiatric and medical diagnoses, read no further.
Disclaimer: Before anyone complains (and in this age of exaggerated political correctness, someone surely will), let me make it clear that I mean no disrespect to people suffering from the illnesses mentioned below. I have the greatest empathy for sick people, and I have encountered several of these conditions in my own family and have actually experienced four of them myself. Humor about them doesn’t offend me, and I hope it will not offend you. Also, my mention of Christmas and Hanukkah songs is not intended to endorse any religious belief.
After a year of serious talk about mostly discouraging things, I thought it was time for a totally frivolous post to cheer us up with a little holiday humor. A friend sent me a list of “Christmas Carols for the Psych Ward.” I thought they were funny, and I’ve copied the best of them below. I’ve added a few of my own for other medical diagnoses, and then I added several about complementary and alternative medicine. (more…)
An article written by 3 chiropractors and a PhD in physical education and published on December 2, 2009 in the journal Chiropractic and Osteopathy may have sounded the death knell for chiropractic.
The chiropractic subluxation is the essential basis of chiropractic theory. A true subluxation is a partial dislocation: chiropractors originally believed bones were actually out of place. When x-rays proved this was not true, they were forced to re-define the chiropractic subluxation as “a complex of functional and/or structural and/or pathological articular changes that compromise neural integrity and may influence organ system function and general health.” Yet most chiropractors are still telling patients their spine is out of alignment and they are going to fix it. Early chiropractors believed that 100% of disease was caused by subluxation. Today most chiropractors still claim that subluxations cause interference with the nervous system, leading to suboptimal health and causing disease.
What’s the evidence? In the 114 years since chiropractic began, the existence of chiropractic subluxations has never been objectively demonstrated. They have never been shown to cause interference with the nervous system. They have never been shown to cause disease. Critics of chiropractic have been pointing this out for decades, but now chiropractors themselves have come to the same conclusion. (more…)
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a somewhat nebulous diagnosis with unknown etiology and no effective treatment. To make the diagnosis, bacterial infection must be excluded and the symptoms must last at least 3 months. Symptoms include pain in various locations (between rectum and testicle, in the testicles, at the tip of the penis, in the lower back, in the abdomen over the pubic or bladder area), pain or burning with urination, frequent urination, pain or discomfort during or after sexual climax. There are also systemic features like decreased libido, myalgias, and fatigue, and there is a higher incidence of chronic fatigue syndrome in these patients. The connection to the prostate is uncertain; in one study, women with chronic pelvic pain reported more of these symptoms than men did. Diagnosis is based on self-reported symptoms; there are no objective diagnostic markers. Somewhere between 2 and 10% of the male population are reported to suffer from this syndrome.
Since there is no effective mainstream treatment for this disorder, why not try acupuncture? Two randomized, placebo-controlled studies have reported positive results from acupuncture treatment. Is this enough evidence for us to recommend it to patients? (more…)
Nasal irrigation with salt water is recommended by 87% of family doctors as an adjunctive treatment to relieve the symptoms of nasal congestion and sinusitis. The simplest method is to hold salt water in your cupped hand, block one nostril while you inhale the water into the other nostril, then blow your nose. The high-tech version is to use a Neti pot, a little jug with a spout. You pour the salt solution from the Neti pot into one nostril and it drains out the other nostril. The technique is described here.
The Neti pot originated in India in Ayurvedic medicine. Neti is Sanskrit for “nasal cleansing.” Other related ancient techniques that have not been adopted by scientific medicine include using a string instead of water and a yoga technique where you close one nostril, pour the solution into the other nostril and allow it to run out of the mouth.
Nasal irrigation provides short-term symptomatic relief and may improve nasal mucociliary clearance. It removes mucus not only from the nose but also from the maxillary and ethmoid sinuses. (more…)
