Douwe Rienstra, MD Educational Activities2006 | 2005 | 2004 | 2003 | 2002 | 2000 - 2001 | 1988 - 1999 Most recent courses are listed first. Note - most of the talks from the University of Washington and the Virginia-Mason Medical Center are presented at Jefferson General Hospital by teleconference. December 16, 2004 - David Relman, MD of Stanford University, spoke at the University of Washington about the many kinds of bacteria that infect humans. He showed DNA evidence that there are many more bacteria and other microorganisms in nature than are in the usual lists and textbooks. Some of these infect humans. Often our tests do not identify the infecting organism, but fortunately our antibiotics are effective. December 10, 2004 - Matt Lee, MD of the Virginia Mason Sleep Disorders Center, pointed out that people slept about ten hours a night before the electric light was developed. Even people sleeping six to eight hours a night have impaired function after just a couple of weeks. After an eighteen to twenty hour work shift, people's work performance is equivalent to what it would be with a blood alcohol of 0.08%. December 3,
2004 - William Lutin, MD from the Medical College of
Georgia, discussed treatment of heart defects in infants and children.
New technology is reducing mortality among these children greatly. June
11, 2004 - Drs O Lin and P Sicuro of Virginia Mason
Clinic, discussed prevention and early detection of colon cancer, the
third leading type of cancer in the US. Eighty percent of cases occur
in people who have no risk factors. Risk factors include family history,
previous colon polyp, inflammatory bowel disease, and the metabolic
syndrome (weight gain, high blood pressure, abnormal cholesterol profile,
elevated blood sugar). The standard recommendation is colonscopy, in
which the colon can be examined and any pre-cancerous polyps removed.
The risk of colon cancer is reduced by exercise May
7, 2004 - Frank Lewis, MD, Executive Director of the
American Board of Surgery, was scheduled to speak about how organized
medicine is losing touch with the American public. This promised to
be an interesting talk, but he announced to his 7:30 a.m. audience that
he had a more pressing topic on his mind. He discussed residency training
of surgeons. (Medical training comprises four years of medical school,
then three to twelve years of residency training to cement the practical
skills. The word "resident" survives from the days that
these physicians lived in the hospital where they trained. They
still spend many nights in the training hospitals working or, when possible,
sleeping. New rules are reducing the work hours for residents to 80
hours per week. Many physicians believe such limits on working
hours will produce less skilled physicians.) Lewis points out that current training programs are not just too
long, they are poorly organized and frequently fail to provide
the education a surgeon needs. The result is that about
30% of physicians will fail their first attempt at passing their
examinations for certification by the American Board of Surgery. As Dr Lewis concluded "We have gotten a lot of mileage out
of a surgical training system developed in the late 1800's. It
is time to change." April 16, 2004 - Paul Mystkowski, MD of Virginia Mason Medical Center, discussed the adrenal gland, which makes cortisol, adrenaline, DHEA, and aldosterone (a hormone thta regulates salt balance and blood pressure). He addresses cortisol in detail, deficiency of which can produce subtle symptoms. We perform adrenal testing in our office and, while familiar with treatment of this condition, did learn some useful wrinkles from Dr Mystkowski's talk. April 9th, 2004 - Drs Kathryn McGonigle and Christina Isacson of the Virginia Mason Clinic, reviewed newer techniques of screening for cancer of the cervic. Or, in plain English, the Pap smear. Pap smear technology is now more expensive on a per-test basis, but is more accurate at detecting cervical cancer and cancer risk. So, women with normal pap smears can be screened less frequently, and women with abnormal pap smears can be evaluated in a less expensive fashion. We have been using the new pap smear technology (called the "thin-prep") for several years. This new technique includes testing for high-risk forms of human papilloma virus, or HPV, which are part of the cause of cervical cancer. March 11th, 2004 - Gary Firestein, MD of UCLA, spoke at the University of Washington about rheumatoid arthritis. He notes that bone changes from this illness have been found in ancient skeletons in the Americas, but not in Europe. In fact, rheumatoid arthritis did not appear in Europe until the 1600's. The significance of this clue is still unknown, as work progresses on the ultimate cause of this terrible illness. February
26th, 2004 - David Schwartz, MD from Duke University,
studies the genes associated with certain lung diseases. Environmental
factors interact with our genetic makeup to produce disease. Schwartz
and other workers are identifying those genes and their varient forms
and working to see why some people with those genes become ill when
exposed to an environmental stimulus, and others with the same genetic
makeup do not become ill. February 6th, 2004 - Kathleen Neuzil, MD and Janet Englund, MD of the University of Washington, spoke at Virginia Mason Clinic about epidemic influenza. The influenza epidemic of 1918 killed more people than the First World War. This could happen again. The best defense is surveillance of poultry in Asia, and immunization. February 5th, 2004 - William Young, MD of the Mayo Clinic, spoke at the University of Washington on the hormonal causes of hypertension. That is, high blood pressure can be the result of tumors in the pituitary gland (cushings syndrome and acromegaly), the adrenal gland (pheochromocytoma and aldosterone-secreting tumor) and so forth. These types of hypertension repond much better to surgery than they do to medication. February 2nd, 2004- Dr Jak Nikomborirak gave an overview of sleep disorders, then focused on sleep apnea. Althouogh a sleep study costs $2000, many times he will give a patient a trial of treatment without it. This is often successful and saves the cash-paying patient a good deal of expense. I had an opportunity at this presentation to experience using the new generation of respirator and was impressed with the comfort of the mask and the ease of using the machine. January 29th to 31st, 2004 - The Tacoma College of Medical Education sponsored an update on general treatment and prevention topics at Whistler, BC. The first speaker, Timothy Schubert, MD, pointed out that screening for colon cancer prevented more mortality per dollar spent than many other prevention strategies. He did not address adequately, in my opinion, the importance of folic acid. Folic acid and other nutrients can, over time, reduce the risk of colon cancer by up to 50%. As well, newer laboratory tests can detect colon cancer in many, but not all people. Richard Schneider, MD, gave one of the best presentations I have heard on the diagnosis and treatment of mood disorders. Mood disorders include anxiety, depression, and bipolar disorder. There are three elements of our mood. One is our background mood - are we generally happy, sad, or what? Second is our "trip-wire" for unpleasant emotionss - do we become depressed with some minor set-back, or does it take a major disaster? Third is the "volume control" - when the "wire is tripped", how bad do we feel? Do we experience a minor case of the blues, or do we commit suicide? People with an anger-management problem are having trouble with this "volume control." Because we all have variations in our neurochemistry, one antidepressant may work better for one person than another. I have been using a system from a Virginia Mason psychiatrist to help me choose the most effective drug for each person based on their symptoms. Dr Schneider presented an elegant scheme based on neurochemistry to choose the best drug to try next, without wasting time on drugs that are unlikely to work when the first one didn't. Bruce Snell, physical therapist, discussed prevention of anterior cruciate ligament (ACL) tears. Female athletes tear their ACL up to eight times more frequently than males. This is because they usually plant their feet and bend the knee in a slightly different way. Training can change these habits. A pilot study looked at girls competing in over 100,000 games of soccer, and found that those girls who had training to improve their knee mechanics had only 10% of the ACL tears of a control group in the first year of the study, and only 25% the tear rate in the second year. Rod Graf, MD, pointed out that the current obesity epidemic is leading to an avalanche of new cases of type 2 diabetes (DM2). (As opposed to type 1 diabetes, which usually starts in childhood, requires insulin always, and is due to destruction of the insulin-producing tissue in the pancreas in children with a particular nutritional and genetic makeup.) Given the current situation, a child born today has about a one in three chance of developing diabetes in his or her lifetime. That means that the child faces a one in three chance of developing the complications of diabetes as well, which include heart disease (including sudden cardiac death), kidney failure, blindness, impotence and infertility, amputation, painful feet, and others. Can the development of DM2 be prevented? Yes, a 2002 study showed that vigorous attention to diet and exercise delays the onset of DM2 even better than the best available pharmacologic agent, metformin. Statin drugs can reduce the frequency of heart disease dramatically. Aggressive treatment of high blood pressure also reduces the risk of cardiac disease. Suzanne Meyer, MS, RD, from Bastyre University gave an overview of her favorite nutrition strategies, strategies that I think all our patients become familiar with. David Heller, MD, a radiologist gave an intensive tutorial on CT colonograpy, a procedure also called "virtual colonoscopy." He disagrees with this term, because the word colonoscopy means to visualize the colon. As practiced, the operator has also the option to biopsy and remove certain lesions, and can determine other illnesses by seeing the color, texture, and pattern of the mucosal lining of the colon. "Virtual colonoscopy" provides none of these things, and is better described as CT colonography, meaning to produce a picture by means of Xrays. To condense his talk, the radiation required to provide optimal images is about two/fifths of the maximum allowable annual exposure allowed in industrial workers, and is equivalent to about 40 chest Xrays. To obtain the best study, a patient still has to put up with a fair amount of pain with laxatives prior to the procedure, with painful inflation of the colon with air, and with some pain after the procedure. Dr Heller reported that he had undergone both colonoscopy and CT colonography and thinks that the former is less distressing. Finally, MRI colonography is coming down the pike, offering much better images with no radiation exposure. In any case, as per the first talk, attention to prevention and early detection of colon cancer can save your life. Janes Cook, MD, a cardiologist, discussed prevention of heart disease, hitting all the current notes of obesity, high cholesterol, and high blood pressure, discussing details of treatment as applicable to different kinds of people. January 25th, 2004 - Jeffrey Bland, PhD gave a talk on nutritional methods of influencing genetic disorders. Bottom line, many conditions such as heart disease, arthritis, cancer, and hormonal disturbances occur because our genetic makeup fares poorly in our particular environment. Genetic tests to help detect this kind of predisposition are becoming more cost-effective. Once identified, you can take steps to prevent or ameliorate these and other disorders. January
23rd, 2004 - Members of the Stroke Team at Virginia
Mason Clinic made several important points. I'll spare you the details,
as the techniques are developing rapidly. The summary is that if you
can reach a major stroke center within a couple of hours, and they know
you are coming, then you may qualify for rapid diagnostic procedures
that can lead to early interventions that lessen the risk of death and
disability. January 21st, 2004 - Richard Thirlby, MD of Virginia Mason Clinic, described his experience as a surgeon treating obesity. Over fifteen years ago he began performing gastric reduction surgery at a time when the procedure was still new. He finds that the roux-en-Y gastric bypass is most effective. Most surgeons limit this surgery to people with a Body Mass Index (BMI) over 40, or BMI greater than 35 if the person has two or more conditions that should improve with weight loss, such as diabetes or high blood pressure. He has seen diabetes resolve in many patients within days of this surgery. Currently over 99% of his patients survive this surgery, compared to the national average of over 95%. On the average, people lose weight rapidly after surgery, then stabilize at about 130% of their ideal body weight. So far, he has been tracking these patients about ten yeaars, and their weight tends to remain stable.
January 16th, 2004 - Fred Govier, MD of Virginia Mason Clinic, spoke about erectile dysfunction, its causes and treatment. There are several causes and treatments, but most of his talk was on sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra). Users of these drugs have a lower heart attack rate than placebo users. Tadalafil has a longer duration of action. Sildenafil will not work as well when taken with a fatty meal. All cost about the same. January 15th, 2004 - Alan Chait, MD of the University of Washington, discussed C-reactive protein and its role in heart disease. Blood tests for C-reactive protein can give a more accurate estimate of heart disease risk than do other tests. We provide this test. January 9th, 2004 - Linda Mihalov, MD from Virginia Mason Clinic, discussed the Women's Health Initiative Study on hormone replacement in women. She covered some of the points we have addressed in our newsletters on this subject. She mentioned black cohosh and said, "it may be beneficial, but there are no long term studies on safety." Of vitamin E, she said, "the studies are all small, the dose is 800 milligrams, and the studies conflict as to whether it is helpful or not. Watch out for bleeding with vitamin E, especially if low in vitamin K." She stated, "I will not address natural hormones as there is little research on long term safety." She discussed raloxifene, bisphosponates, selective-serotonin re-uptake inhibitors, and numerous forms of synthetic estrogen and progesterone. My comments: black cohosh is very helpful for many women, and much less likely to cause long-term problems than a synthetic agent. Vitamin E is more effective for menopausal symptoms at a dose of 1400 units a day. It may help, may not, and is very unlikely to cause bleeding. Regarding natural hormones, it is very nice to be concerned with long-term effects of natural estrogen and progesterone, but there is no reason to believe that anyone will step forward to spend millions of dollars to study this. For many years there has been evidence that estrogen from mares has an unusually stimalating effect on the human breast. And the Women's Health Initiative Study showed that indeed, this form of estrogen conbined with synthetic progesterone did increase the risk of breast cancer. So, what do you choose, something we suspected was bad and has been shown to be so? Or something we have reason to believe is more benign? Women who have their ovaries removed in their thirties have less breast cancer. This leads to two conclusions.
January 8th, 2004 - Doug Merrill, MD from Virginia Mason Clinic, spoke on the physiology and treatment of chronic pain. I learned a new benefit of tylenol and the new COX-2 inhibitors, which is that they cross the blood brain barrier and provided benefits that aspirin, Advil, Aleve, etc. do not. Specifically, COX-2 inhibitors and tylenol calm receptors for pain in the brain that cannot be reachced by ordinary NSAIDs.
People who have real pain and take pain medication do not get addicted. |
