Hello world!By Temporary | May 5th, 2008 Welcome to WordPress. This is your first post. Edit or delete it, then start blogging! ------------------------------ Spread the Word: ------------------------------ Healing EverythingBy Dr. Richard G. Petty, M.D. | April 23rd, 2008
I get a huge number of requests for more information about my philosophy of health and healing; where it came from, and why people believe that my approach is the medicine of the future: hence the amusing title of “The Future Doc.” My belief in an “integrated” approach to health and healing, that engages the physical, psychological, social, subtle and spiritual aspects of life is not confined to the treatment and personal growth of individuals. It also encompasses ecology, sociology and business practices. In many respects I have followed a similar path to Ken Wilber, but while he has been the theorist par excellence, whose ideas are now being test-driven in a multitude of different applications, I started from personal perception and clinical practice. I talk about some of the origins of my work in Healing, Meaning and Purpose. It is well-known that I had the privilege of working with the Prince’s Foundation for Integrated Medicine, which is now the Foundation for Integrated Health, and I recently came across this statement by His Royal Highness The Prince of Wales in the magazine Temenos that beautifully summarizes the philosophy that underlies the entire approach.
Prince Charles has also said that,
Our lives depend on it. ------------------------------ Spread the Word: ------------------------------ An Extraordinary New BookBy Dr. Richard G. Petty, M.D. | April 8th, 2008
Regular readers will know that I sometimes review books at Amazon. I only review around 10% of the books that I read, and they are ones that I think are consistent with my aims of improving the quality and quantity of our lives. I belong to the “If you cannot say something nice, say nothing” school, so I don’t review a book unless it is special and brings something new to the table. Unless somebody has written something that is just plain wrong! A few months ago I was at a meeting in New York and met a man named Kurek Ashley. I have met more than my fair share of people from every continent, and it is not often than someone impresses me: Kurek did. Not because he was a larger than life person, but because of his heart and soul. I asked to have a look at his book, which at that stage was not published. It really surprised me, and I read it twice in once weekend while shuffling to and from the West Coast. The book is published today as How Would Love Respond?: Imagine If You Were Given a Gift So Powerful That You Knew You Had to Share It with the World, and I was so impressed that I helped with the launch. Here is what I had to say in my review,
As part of the celebration of the launch, experts from all over the world who have read and been moved by the book have contributed gifts and bonuses. They are all interesting, and many will likely to of value to anyone reading this. I have offered two eBooks and a set of audios. This is a bit of blurb that was written about my piece:

Although textbooks and pharmaceutical company literature often claim that the biological component of depression has been clearly defined, the fact is that we still have no certain knowledge about the molecular and biochemical disturbances in depressive disorders. Furthermore, our theories of how antidepressants are constantly being revised, and it is now thought likely that these drugs have several mechanisms of action. There is an interesting study from the University of Illinois at Chicago College of Medicine and Maryland Psychiatric Research Center in Baltimore in today’s issue of the Journal of Neuroscience. They have discovered that a change in the location of a protein in the brain could serve as a biomarker for depression. This is exceptionally important, since it may give us a simple and rapid laboratory test to identify patients with depression and, more importantly, to predict clinical response to specific antidepressants. Over the last few years this same team of researchers, and others around the globe, have been examining a protein named Gs alpha that activates adenylyl cyclase. Adenylyl cyclase is a link in signal transduction that is in part responsible for the action of neurotransmitters including serotonin. Instead of just looking at the biochemical properties of the protein, they have also been looking at the way that it moves in the cell membrane, which in turn impacts the way in which neurotransmitters act on cells. In both rats and cultured brain cells, Gs alpha changes its location in response to antidepressants, moving out of lipid “rafts” in the cell membrane, to areas of the membrane that allow more efficient communication among membrane components responsible for the action of neurotransmitters. Both antidepressant and antipsychotic drugs have been shown to concentrate in these lipid rafts. In this new study, brain samples from depressed people who had committed suicide were compared with controls who had no history of psychiatric disorders. Although the total amount of Gs alpha was the same in the depressed and non-depressed, in people with depression, Gs alpha was stuck in these lipid “rafts.” Therefore the protein is unable to do its job of mediating the action of neurotransmitters. Antidepressants have the opposite effect, moving it to regions of the membrane where it can do its work. The localization of other G proteins was not different. This is such a robust finding, that identifying the location of Gs alpha in the cell membrane may provide an objective diagnosis of depression and second, whether someone is responding to the chosen antidepressant therapy. The senior author in this research is Mark Rasenick, who is distinguished university professor of physiology and biophysics and psychiatry at the University of Illinois. He described the lipid “rafts” and the importance of the findings like this:
------------------------------ Spread the Word: ------------------------------ The Price of a PlaceboBy Dr. Richard G. Petty, M.D. | March 7th, 2008
Placebos can be powerful things, whether they come wrapped in a nicely colored box, or take the form of an enthusiastic clinician. Dan Ariely, a behavioral economist at Duke University, and author of the excellent new book Predictably Irrational has written a letter in this week’s issue of the Journal of the American Medical Association in which he suggests that pill costing ten cents is not as effective at preventing pain as a $2.50 pill, even when they are identical placebos. Ariely and a team of collaborators at the Massachusetts Institute of Technology recruited 82 people to participate in a study in which light electric shocks were administered to participants’ wrists to measure their subjective rating of pain. The 82 study subjects were tested before getting the placebo and after. Half the participants were given a brochure describing the pill as a newly approved painkiller that cost $2.50 per dose. The other half was given a brochure describing it as marked down to 10 cents, without saying why.
As Dr. Ariely says,
Would it help if prescription medications offer cues from packaging, rather than coming in indistinguishable brown bottles? Is there a way of giving people cheaper or generic medications without them thinking they will not work? As Dr Ariely says,
“It requires a great deal of faith for a man to be cured by his own placebos.” “Your thoughts are like the seeds you plant in your garden. Your beliefs are like the soil in which you plant these seeds.” “Change your beliefs and you change your destiny.” ------------------------------ Spread the Word: ------------------------------ Testing for Diabetes in ChildrenBy Dr. Richard G. Petty, M.D. | March 7th, 2008
Diabetes mellitus can be a devastating illness, especially when it comes on suddenly in a child or adolescent. In young people it is usually so-called Type 1, or insulin-dependent diabetes, an autoimmune disease in which the immune system attacks the insulin-producing beta cells in the pancreas. The disease can have a major impact on the whole family, and sometimes people forget the way in which it can affect siblings whose needs often need to be subordinated to the needs of the newly diagnosed young person. And here is an important point: even when it appears suddenly, the disease process may have been going on for some time before the clinical symptoms appear. By the time that blood glucose levels begin to rise, it usually implies that the damage to the insulin-producing cells in the pancreas has reached a critical point, and the chance of recovery is low. Anything that we can do to prevent the disease from progressing to the point of producing symptoms would be immensely helpful, and that starts with early recognition before the pancreatic damage has reached critical. Although we now understand a great deal about the interplay of genetic, environmental and immunological factors that may lead to the illness, this knowledge has so far not helped us very much. There has been a tremendous need to try and identify the early stages of the disease, but that goal has been elusive. In a study published in the Journal of Immunology researchers from the University of Queensland’s Diamantina Institute for Cancer, Immunology and Metabolic Medicine, are developing a simple test that may predict whether a child will develop Type 1 diabetes. They have identified a cellular pathway known as NF-kappa B that is activated in certain blood cells – monocytes and dendritic cells – of people with Type 1 diabetes. In healthy people monocytes remain quiescent unless they are activated by an infection or other stressor. Then the NF-kappa B pathway gets activated. In people with Type 1 diabetes things work the other way round: monocyte NF-kappa B was already activated in the blood, and when exposed to infection the pathway shut down. This tells us that there is a problem of immune control that may cause diabetes to develop in children. It is this monocyte abnormality that will hopefully form the basis of a diagnostic test. This work is assuming more urgency since there are several trials of diabetes vaccines underway, and if successful, it may become possible to identify and intervene in children at risk of Type 1 diabetes before it occurs. In addition, understanding why the immune system loses control before the disease starts should open up a number of new options for prevention and treatment. ------------------------------ Spread the Word: ------------------------------ A New Treatment for ToxoplasmosisBy Dr. Richard G. Petty, M.D. | March 6th, 2008
I have talked at some length about the possible link between toxoplasmosis and some forms of mental illness, but there is also another side to toxoplasmosis: the Toxoplasma gondii parasite infects nearly one-third of all humans: more than two billion people worldwide. In the United States alone, congenital toxoplasmosis occurs in an estimated 1 per 5,000 births a year and can cause severe vision loss, brain damage and even death. The human cost is incalculable, and in dollars and cents, it has been estimated that the annual cost of caring for these children may exceed $1 billion. Toxoplasma gondii is carried by some cats and it is said that an infected cat can excrete up to 20 million oocysts over a period of two weeks, and every single oocyst is infectious. They are tenacious and can remain infectious in water for up to six months and in warm moist soil for a year of more. Toxoplasma infects humans through three main routes:
It is even possible for people with normal immune systems to suffer major organ damage from chronic infections. Eye disease leading to loss of sight can be caused both a primary infection and as a result of infection transmitted from mother to child. Damage to other organs has recently caused deaths among otherwise healthy young people during epidemics in Surinam and French Guiana. The parasites that cause malaria are related to Toxoplasma gondii, and a new drug that will soon enter clinical trials for the treatment of malaria also appears to be 10 times more effective than the current gold-standard treatment of toxoplasmosis, a combination of the drugs pyrimethamine and sulfadiazine. In the March issue of PLoS Neglected Tropical Diseases, a research team based at the University of Chicago Medical Center reports that the drug, known as JPC-2056, is extremely effective against Toxoplasma gondii, both in cell culture and in mice, and apparently without the toxicity associated with the current standard treatment. The drug works inhibiting the action of the from of the enzyme dihydrofolate reductase (DHFR) that is produced by the family of parasites that includes those that cause toxoplasmosis and malaria, and in cell culture studies, the drug appears actually to kill the parasite, rather than simply preventing its replication. This is very important: not only do most of the current medications have a good many side effects, they have little effect on Toxoplasma during certain phases of its life cycle. It can hunker down in the quiescent cystic phase and wait until the antibiotics are gone. Rima McLeod, professor of ophthalmology and specialist in infectious diseases at the University of Chicago said,
------------------------------ Spread the Word: ------------------------------ Career ContentmentBy Dr. Richard G. Petty, M.D. | March 4th, 2008
As you will see from my review, I just love the book, and it is amazing how Jeff’s work and mine fit together. We are going to be having a panel discussion about the book on www.Business.VoiceAmerica.com on Thursday March 6th at 3PM Eastern, which is noon Pacific time. The discussion is also going to be archived for people in other time zones. I plan to put up a link as soon as it is available. There is a nice press release here. I hope that you can listen in: I think that you will get a lot of food for thought! “Contentment is natural wealth, luxury is artificial poverty.” ------------------------------ Spread the Word: ------------------------------ Men, Women and ForgivenessBy Dr. Richard G. Petty, M.D. | March 4th, 2008
We recently discussed the importance of forgiveness on health. Over the years studies have shown that men tend to be more vengeful than women, presumably because they have been taught from childhood to empathize with others and build relationships. Though there could yet be a biological basis for this difference. New data from Case Western Reserve University, Florida State University, Arizona State and Hope College published in the Journal of Personality and Social Psychology suggests that forgiveness does not come naturally for both sexes. Psychologist Julie Juola Exline’s research indicates that men have a harder time forgiving than women do. However that can change if men develop empathy toward an offender by seeing they may also be capable of similar actions. That empathy closes the gender gap and men become less vengeful. The authors conducted seven forgiveness-related studies (1,2,3,4,5,6,7) between 1998 and 2005 that involved more than1,400 college students: Gender differences have been a robust finding. The studies used hypothetical situations, actual recalled offenses, individual and group situations and surveys to study the ability to forgive. When men were asked to recall offenses they had committed themselves, they became less vengeful toward people who had offended them. Women started at a lower baseline for vengeance, but thinking about their own transgressions had no effect on levels of unforgiving. When women were asked to recall a similar offense in relation to the other’s offense, women felt guilty and tended to magnify the other’s offense. The researchers found that people of both genders are more forgiving when they see themselves as capable of committing a similar action; it tends to make the offense seem smaller and increases empathic understanding of the offense. Therefore people similar to the offenders and therefore more forgiving attitudes. The ability to identify with the offender and forgive also happens in intergroup conflicts. In a study on forgiveness of the 9/11 terrorists Exline comments that, “When people could envision their own government committing acts similar to those of the terrorists, they were less vengeful. For example, they were less likely to believe that perpetrators should be killed on the spot or given the death penalty, and they were more supportive of negotiations and economic aid.” It is not difficult to see that prosecution and defense attorneys are going to study this data carefully. It will likely come into play during jury selection processes. And I am going to think about it the next time that I am called upon to serve on a medical school interview board. “An eye for an eye will only serve to make the whole world blind.” “And be ye kind one to another, tenderhearted, forgiving one another, even as God, for Christ’s sake, hath forgiven you.” “Everyone and everything I see will lean toward me and bless me. I will recognize in everyone my dearest friend. What could there be to fear in a world that I have forgiven, that has forgiven me?” ------------------------------ Spread the Word: ------------------------------ A Stunning VideoBy Dr. Richard G.
