Therapeutic Eyecare
The therapeutic care of chronic disease should be and will be a major element of both patient care and revenue for the eyecare practice in the next decade.
J. James Thimons, OD, FAAO.May 2005.
Principles of Integrative Medicine
A partnership between patient and practitioner in the healing process Appropriate use of conventional and alternative methods to facilitate the body's innate healing response A philosophy that neither rejects conventional medicine nor accepts alternative therapies uncritically Use of natural, effective, less-invasive interventions whenever possible
Naturopath (ND)
First, do no harmEmploy the healing power of natureIdentify and Tx the causeTreat the whole personThe physician is a teacherPrevention is the best cureEstablish health and wellness

Expedient “Symptom” or Disease CareHighlights – Michael T Murray, ND
US is #1 in %GDP spent on health.We use 40 % of all worldwide medications.700,000 US physicians @ estimated $60,000 per year in marketing per physician.1992 average senior used 19.6 Rx / year.2005 average senior used 34.4 Rx / year.Simple measures:
Example - Vitamin C, D and Fish oil ignored.
What is Integrative Medicine?Integrative medicine is a healing-oriented medicine that takes account of the whole person (body, mind, and spirit), including all aspects of lifestyle. It emphasizes the therapeutic relationship and makes use of all appropriate therapies, both conventional and alternative. AKA: CAM (complimentary and alternative medicine).Integrative Optometry follows these same principles.
What is a Nutraceutical?Nutraceutical can be defined as, "a food (or part of a food)
that provides medical or health benefits, including the prevention and/or treatment of a disease."
However, the term nutraceutical as commonly used in marketing has no regulatory definition.
* “Prescription drugs are approved through the rigorous new drug application process (NDA). In contrast, dietary supplements are regulated as foods and the FDA must determine that a dietary supplement ingredient poses a "significant or unreasonable risk of illness or injury"•About $7 billion spent on vitamins & $31 Billion spent annually on dietary supplements, herbal foods and products.
RDA = Recommended Daily Allowance-”prevent 97% of deficiencies”RDI = Recommended Dietary Intake

Many senior Americans don’t develop sufficient antibodies after flu shots because of poor nutrition.
Heartburn HCL hydrochloric acid and pancreatic enzyme are secreted less with advancing age; replace with supplements; if symptoms persist try mastic gum, aloe vera
Heartburn drugs may cause osteoporosis due to loss of vitamin D and fatigue due to vitamin B12 depletion.
Chronic headache
Our first remedy is to thin the blood as increased viscosity is a primary cause in our experience; garlic oil, magnesium, fish oil, bromelain, turmeric, ginkgo, ginger, ginseng, cayenne pepper, feverfew, nattokinase
See a health professional if symptoms persist.

“It is a distortion of priorities for much of the world's population to have an inadequate intake of vitamins or
minerals—at great cost to health—when a year's supply of a daily
multivitamin/mineral pill costs less than a few packs of cigarettes. The poor, in general, have the worst diets and have the most to gain from improving their
multivitamin and mineral supplementation and diet,” says Dr. Ames. [European Molecular Biology Organization) Journal (6, S20–S24,
2005]
RDAs needs to be updated to reflect new scientific studies
RDA for vitamin C was based on flawed data (half life of vitamin C was never calculated). Virtually all humans on the planet are vitamin C deficient.Vitamin D is not toxic at relatively high doses and major segments of the US population are suffering from diseases related to vitamin D deficiency (cancer, autoimmune disease, hypertension, bone loss). Fortification of foods with vitamin D would likely cause cancer rates to decline by as much as 30%. 40% of adults over age 50 experience signs of vitamin B12 deficiency (short-term memory loss, fatigue, nerve tingling) because of a decline in the production of stomach acid.

Increasing Rx Pharmaceutical & OTC Safety Concerns
• In 2007, Americans spent around $300 Billion on FDA approved prescription & OTC drugs• 700,000 ER visits for overdoses & allergic rxns each year • (2005) 15,000+ died from drug reactions compared to 5,519 people in 1998• fatalities linked to generic pain pills (oxycodone, fentanyl,
morphine & acetaminophen or Tylenol)• (2005) 89,482 serious side effects to the FDA• 2.5 X the 34,966 reported in 1998• More than half of all approved drugs (like Vioxx) produce serious side effects not detected prior to approval. [Journal American Medical Assn. 279: 1571-73, 1998] • only 3% of prescription medicines have been withdrawn from the American market for safety reasons over the last 20 years.'
Drug Induced- Nutrient Interactions(examples)
Chronic use of proton pump inhibitors for dyspepsia and gastroesophageal reflex disease (GERD) can induce vitamin B12 deficiency, which may cause secondary effects on optic nerve function.
Chronic or high dose acetaminophen use may induce glutathione deficiency, which accelerates cataract formation and yields myriad effects on ocular tissues.
Overuse of steroids, such as dexamethasone and prednisolone, can induce deficiencies of vitamins C and D, folic acid, zinc, potassium, magnesium and selenium.
COQ10 Depleters--- statins, beta blockers, metformin
Even OTC Pharmaceuticals can induce nutritional deficiencies which are often treated
with additional pharmaceuticals

“Prescription drugs have an intended effect on the body but they may be reducing vital nutrients in your cells causing all sorts of annoying and dangerous side effects. For example, cholesterol-lowering statin drugs mug you of Coenzyme Q10, which powers your heart beat and keeps you from becoming weak, or developing leg cramps. Estrogen-containing drugs mug you of certain nutrients, leaving you hypothyroid, depressed and tired. Diabetic medications mug a certain B vitamin that protects you from stroke & heart attack. There are hundreds of medications included as well as drug-food interactions (like grapefruit, oatmeal and cheese interactions that could harm you)... “

“20 cherries reduces inflammation in a similar manner as aspirin or Cox-2 inhibiting drugs without the lethal side effects of gastric bleeding or vitamin depletion associated with these drugs” The molecules in cherries, called anthocyanins, work to reduce inflammation at ten times less dosage than aspirin. [Journal Natural Products 1999 Feb; 62(2): 294–6]

Cherrios – 12 May 2009FDA questions General Mills' Cheerios marketingTriangle Business Journal - by Joey Peters Minneapolis/St. Paul Business JournalThe FDA told General Mills to stop promoting Cheerios, the country’s best-selling cereal, as a product that can lower cholesterol levels, reduce heart disease and reduce the risk of cancer. The agency said that claiming the cereal can lower cholesterol levels by 4 percent in six weeks amounts to marketing it as a drug and violates the federal Food, Drug and Cosmetic Act. In a prepared statement, General Mills (NYSE: GIS) said the complaint doesn’t question whether the cereal actually lowers cholesterol levelsand said the dispute is over language, not science.“The scientific body of evidence supporting the heart health claim was the basis for FDA’s approval of the heart health claim, and the clinical study supporting Cheerios’ cholesterol-lowering benefit is very strong,”. “We look forward to discussing this with FDA and to reaching a resolution.”Cheerios boxes say that two, one-and-a-half-cup servings of the cereal every day have been clinically proven to lower cholesterol. The message has been on the box for more than two years.
BRITAIN: Tea Council under fire
Sept 26, 2007 - The UK Tea Council has been criticized for exaggerating the benefits of tea and banned from making further claims about the drinks antioxidant potential after running a series of adverts.
The group came under fire after five people complained to the Advertising Standards Authority (ASA) about a media campaign which recommended drinking four cups a day as part of a healthy diet.
……despite the UK Tea Council (UKTC) submitting nearly 100 scientific studies backing up tea's health potential, the ASA said it had not seen evidence to "firmly substantiate" any health benefit in drinking four cups of tea per day and said the campaign "exaggerated" the health benefits.
…..under regulation (EC) No 1924/2006, which came into force in the UK from 1 July 2007, any food product claiming to have a health benefit must meet a list of European Commission approved wording and be supported by scientific evidence.
Patients need better nutrition and higher doses of vitamins as they age *Mal-absorption including gastric hypo-chlorhydria occurs with age, disease and use of acid blockers.As we age, the ubiquitin system (Nobel Prize 2004) becomes less efficient due to free radical attack and glycosylation.We have accumulated more free radical DNA hits with less efficient repair.We become increasingly cross-linked and rigid due to carbonyl and glycosylation end products.

Taking an aspirin every day is nearly as risky as working as a firefighter.
For 50-y/o men, taking a daily aspirin (which many do to help prevent heart disease and strokes) increases the risk of death by the equivalent of 10.4 deaths per 100,000 men per year. Similar to the added risk that professional firefighters face. Firefighters have an added risk of 10.6 deaths per 100,000 people per year, compared to 3.9 for all occupations and 0.4 foroffice workers.In comparison, drugs that have been withdrawn from the market, such as the painkiller Vioxx and the multiple sclerosis drug Tysabri, increased the risk of death by 76 deaths per 100,000 people per year and 65 deaths per 100,000 people per year, respectively. Tysabri may be reintroduced to the market if the FDA deems it worth using despite the risks.Adverse drug events harm more than 1.5 million people and kill several thousand a year, costing at least $3.5 billion annually.

Discriminately READ Scientific StudiesTypes of Studies – don’t discount multiple
observations, but look at Power CalculationBias – “follow the $”* Absolute Risk - pay close attention to this oneRelative Risk – “ where’s the beef ”Odds Ratios - look for statistical significanceSignificance - is p = 0.06 worthy of our attention?Meta-analysis – was there selective inclusion ?
Bias is still possibleDo conclusions understate or overstate the data ?“Made in America” bias
Is academic medicine for sale ?“No, the current owner is very happy
with it”
1.Why are you prescribing this drug? 2.Are there older & safer less
expensive drugs ?3.Is a drug needed at all for this mild
case? Marcia Angell, MD former Chief Editor , NEJM "The Truth About the Drug Companies: How TheyDeceive Us and What to Do About It" (Random House, 2004).
How do we avoid “Disease Mongering” ?includes turning ordinary ailments into medical problems, seeing mild symptoms as serious, treating personal
problems as medical, seeing risks as diseases & framing prevalence estimates to maximize potential markets.
A recent report in the Columbia Journalism Review of the news media’s complicity in drug marketing http://www.cjr.org/issues/2005/4/lieberman.asp notes that noted medical journalists chose not to warn the American public of the potential dangers posed by Vioxx because pharmaceutical advertising is now a primary source of income for television and newspapers.

Relative risk or “Sleight of Hand”(i.e. Headline “Cholesterol-lowering statin drugs lower the risk
for a heart attack by 30%”)A naïve reader would get the false impression that these drugs will result in 30 fewer heart attacks per 100 statin drug users Let’s say heart attacks occur among 3% of 1000 patients over 5 years -- that would amount to 30 heart attacks. A 30% relative risk reduction of 30 would be 9 less heart attacks (21 total over 5 years). That’s 2 heart attacks that were prevented every year among 1000 statin drug users, or just 0.2% difference (2/10ths of one percent) between users and non-users of statin drugs.Some 1,825,000 statin pills would be consumed to prevent 9 heart attacks –but not 9 lives saved. 4 statin drug trials 67 of 7065 (0.948%- 9/10ths of one-percent) statin drug users died
102 of 7054 (1.446% - nearly 1½ of one percent) who did not take the drug*An absolute difference of 0.498% (1/2 of one percent, absolute difference). [British Medical Journal 323: 1-5, 2000]

JAMA 293:1338-47, 200519 studies, 135,000 people“400 IU increased risk of dying by 4%”What researchers claimed was that high-dose vitamin E increased the risk of heart failure by a whopping absolute 1% risk among people who took three drugs that induce heart failure (diuretics, statin drugs and beta blockers). The vitamin E got blamed for the problem & worse yet the researchers eliminated studies where there were no deaths and 2 studies with 2000 IU that showed a decrease!12% reduction in death in AREDS34% reduction in MIs & 49% reduction for high risk females over age 65 in the Womens Health Study, JAMA 294: 56-65, 2005

Beta Carotene
High dose Vitamin A and Acutane® should be avoided by women who might become pregnant, patients with liver disease and those who drink heavily.
However vitamin A from B Carotene is produced on an “as needed” basis.
Consider the issue of competition with D, another fat soluble vitamin, when talking about the bone mineralization issue.

The predictive power of coronary artery CA++ scores
Among subjects whose coronary artery CA++ scorewas zero, the risk for any adverse coronary event was only about one-half of 1% (0.0044), or less than 1 in 200.
Those with a coronary CA++ score over 300, about 8.0% experienced an adverse event involving coronary arteries (0.0804), or about 8 in 100, an 18-fold difference (1800% !), over the 3.8 year period.

200 ug Selenium & increased risk of DM IIN=1202; self report of DMNational Prevention of CA trialThe claim is that, after 7.7 years of use, a 200 microgram selenium supplement increased the risk for diabetes by 50%.A large long-term study reported in
1994 that the same dose of selenium resulted in a dramatic decline in cancer incidence Mechanism: There is animal data showing that selenium, which helps to produce an antioxidant enzyme called glutathione peroxidase, may trigger over-expression of this enzyme which could possibly increase the inability of insulin to enter cells (called insulin resistance).

Fish oil & Coagulation StatusWarfarin is an oral anticoagulant used to control and prevent thromboembolic disorders. The dose is adjusted to maintain
the patient's prothrombin time (PT) international normalized ratio (INR) within a recommended therapeutic range.
CASE REPORT Ann Pharmacother. 2004 Jan;38(1):50-2. Omega-3 fatty acids may lower thromboxane A(2) supplies within the platelet as well as decrease factor VII levels. Although controversial, this case report illustrates that fish oil can provide additive anticoagulant effects when given with warfarin. CONCLUSIONS: This case reveals a significant rise in INR (2.8 to 4.3) after the dose of concomitant fish oil was doubled (1 g to 2g) . Patients undergoing anticoagulation therapy with warfarin should be educated about and monitored for possible drug-herb interactions.
STUDY: J Thromb Thrombolysis. 1998 Jul;5(3):257-261.Effects of Marine Fish Oils on the Anticoagulation Status of Patients Receiving Chronic Warfarin Therapy….. “Fish oil supplementation in doses of 3-6 grams per day does not seem to create a statistically significant effect on the anticoagulation status of patients receiving chronic warfarin therapy”.

Intellectual Morons
1. Admit they read only 4 journals 1. (i.e NEJM, AMA, Annals Inter Med, Lancet)
2. Don’t have time to research material that would improve a patient's care
3. Would be so obstinate and filled with so much self-importance they would allow a patient to die rather than try something that had strong clinical evidence of benefit without any complications
