By the end of this session, you will
Review new data that will change your practice about common medical
problemsReconsider what you might assume
is the “standard of care” Remain skeptical of how the medical
literature influences the news, your patients, and someone’s income
Which of the following is a result of Chronic PPI Use?
1. ↑ Hip Fracture2. ↑ Community Acquired Pneumonia3. ↑ Rates C. difficile4. No Improvement in Asthma Control
5. ALL OF THE ABOVE
PPIs & Hip FracturePPI -> Hypochlorhydria -> ↓ Calcium Absorption Review of 1.8 Million Brits aged >/= 50 yrs13,556 Hip Fractures; After adjusting for cofounders Relative Risk of Hip Fracture among PPIs (> 12
months) = 1.6 [CI: 1.41-1.89]Risk Increased w/ duration of Tx & with ↑ dosesUse of H2 RAs were analyzed; NO ↑ Risk

Asthma & GERD 700 patients: inhaled corticosteroids treated with
Nexium 40 mg bid or placebo Divided into 3 Groups:1. One group had nocturnal asthma and no GERD, 2. One had GERD and no nocturnal asthma, 3. and one had both GERD and nocturnal asthma.
***Nexium did NOT improve any clinically significant Sx: morning PEF, use of rescue inhalers, or quality-of-life scores in any subgroup

3. Drugs: Show of Hands“How many times in the past year have
you used an illegal drug or used a prescription
drug for non-medical reasons?”
~400 patientsGold Standard: DAST-10 + Oral Fluid
Testing
Sensitivity: ~100%Specificity: ~75%
Arch Intern Med 2010: 170(13): 1155-60
Sources of Drugs: You & Me
Diversion: Unintended use of medication for unlawful
purposesUsing Pseudophedrine for Crystal MethUsing lawfully prescribed medications
(narcotics, anxiolytics, amphetamines) for illegal purposes
Diversion Perspective$8 Oxycontin sells for >$100.00 on street
Drug FactPrescription Opioids cause more
drug overdose deaths than cocaine and heroin combined.
40% of teens and an almost equal number of their parents think abusing prescription painkillers is safer than abusing "street" drugs
CDC/FDA 2008
30 Deaths/Day
Prevalence of STI’s: 14-19 Females838 females who completed a National Health
& Nutrition Examination Survey 2003-04Specimens (urine, self obtained vaginal
swabs) GC, Chlamyida, Trichomonas, HS II, ↑ Risk
HPV24% were + for at least 1
HPV: 18.3% Chlamydia: 3.9%Trich: 2.5% HSV: 1.9%GC: 1.3%
Pediat 2009; 124: 1505-12
4. DiabetesUpdate on the ACCORD Trial
Gluc: A1C-- lower is not better
BP: 120 not better than 140 to prevent Endpoints: Non-fatal MI, CVA or CHD Death
Lipids: adding fibrate to statin did not decrease end points and may, in women,
increase adverse outcomes
NEJM; 2010: 362(17): 1628
Landing on the U-Shaped CurveWhere is the Ideal A1C ???
2 cohort studies, ~28,000 T2DM >/= 50 Yrs Compared Mean A1C and All Cause Mortality
A1C Hazard Ratio for Death
6.4% 1.5210.4% 1.79Insulin based vs. oral agents 1.49
Conclusion: Ideal A1C Level was 7.5%
NEJM 2010: 362(17): 1563
Editorial: Glycemic Control in Type 2 Diabetes: “Time for an
Evidence-Based About Face”“Tight glycemic control burdens patients with complex
treatment programs, hypoglycemia, weight gain, and costs, and offers uncertain benefits in return.
“Glycemic control efforts should individualize A1C targets so that those targets and the actions necessary
to achieve them reflect patients’ personal and clinical context and their informed values and
preferences”
Montori; Ann of Intern Med 2009; 150: 803-808
American Diabetes AssociationAmerican College of Cardiology Foundation
American Heart AssociationJoint Position Statement
“intensive vs. standard glycemic control have not shown a significant reduction of CVD outcomes”
Tx Goals: “Blood pressure control, Lipid Lowering w/Statin, ASA & Lifestyle modification”
AND:
A1C < 7.0: “w/o Hx hypoglycemia, short duration of DM, long life expectancy, no CVD”
A1C > 7.0: “w/ Hx hypoglycemia, limited life expectancy, advanced micro or macrovascular complications, extensive co-morbidities, or long standing DM in whom the general goal is difficult to attain…”
Diabetes Care 2009; 31(1): 187-192
Aspirin Recommendation for DM?
AHA, ACC, ADA Position Statement on Primary Prevention in Diabetes
Meta Analysis of 9 RCTs of Aspirin1. Low Dose ASA is “reasonable” for Pt with 10
Yr CVD risk > 10% & no risk for bleeding2. ASA should NOT be recommended for men <
50 or women < 60 Yrs with no other CHD RF3. ASA MIGHT be acceptable in the 5-10% risk
Diabetes Care 2010; 33: 1395

5. GoutLow Dose Colchicine
RCT of 1.8 mg in 1 hour (1.2 onset, 0.6 in 1 Hr) vs
4.8 mg in 6 Hr (1.2 onset, then 0.6-1.2 per hour)
Outcome was >50% reduction pain @ 24 Hr and Adverse Event
Pain AE (D, SD, V)

New Trends: Rx that Reinvent Colchicine:
Generic: 30 Pills $25Colcrys 30 Pills $170
Acetic Acid/Hydrocortisone OticGeneric 15 ml $8Brand Name 15 ml $210.00
Doxepin (Sinequan)Generic 10 mg $19/90Brand 3, 6 mg $118/30Pill Cutter $ 2.00
6. Low Back PainWhat Predicts Chronic Low Back Pain
SR of 20 studies (10,000+ Patients) to see what predicts Chronic LBP at 1 Year
Median LRNon-Organic Signs 3.0Mal-adapative Coping Behav. 2.5Functional Impairment 2.1Psychiatric Co-morbidities 2.2Low Health Status 1.8
JAMA 2010; 303(13): 1295
Opioid Use & Acute LBP Early opioid Rx & subsequent disability from back
injuries “Receipt of opioids for >6 days doubled odds of
disability”Spine 2008:15;33(2):199-204.
Relationship between early opioid prescribing for acute occupational low back pain and disability duration
8000+ Workers Comp Cohort Pts who received Opioids disabled 69 days longer than not.
“CONCLUSION: Given the negative association between receipt of early opioids for acute LBP and outcomes, it is
suggested that the use of opioids for the management of acute LBP may be counterproductive to recovery.”
Spine 2007; 32(19):2127-32
7. Pain ReliefRunning Hot or Cold
RCT of 60 adults w/Acute Neck or Back pain400 mg Ibuprofen + Ice or Heat Pack x 30
Min“no difference in pain severity in Cold or Heat groups before or after treatment” or in
need for additional medication80% would use same approach for next injury
Acad Emerg Med 2010; 17(5): 484
Osteoarthritis and the KneeRCT of ~225 patients with OA of Knee Usual Care (home exercise, NSAIDs, PT)
vsSpa Therapy (18 days “hydrojet Tx,
massage under mineral water, mineral mud & mineral pool exercises) + Usual Care
At 6 months: 50% of Spa vs 36% of Usual Care had “Minimal Clinically Important Improvement”
Ann Rheum Dis 2010; 69: 660
Migraine: Aspirin, really??SR of 13 studies; 4000+ASA (1000 mg + 10
metoclopramide) vs others agents (Sumatriptan 50 or 100 mg)
“Sumatriptan 50 mg did not differ from ASA alone at 2 Hr Pain Free & HA relief”
Sumatriptan 100 mg was better than ASA+Meto At 2 hour Pain Free, BUT NOT HEADACHE RELIEF & had > Side Effects
Cochrane DSR 2010
Acetaminophen & NSAIDs Together, again
SR 21 studies, 1900 patients for Pain ControlParacetamol vs. NSAID vs Para+NSAID“Combination of Para. And NSAID was more
effective than Para. Or NSAID alone in 85% and 64% of relevant studies, respectively”
“Current evidence suggests that a combination of Para. And an NSAID may offer superior analgesia compared to either drug alone.
NO increase in adverse events from combination
Anesth Analges 2010; 110: 1170
8. Food and DrugsGrapefruit Juice & Statins
Grapefruit Juice inhibits intestinal C P-450 3A4
Can inhibit first pass metabolism and may result in ↑ serum concentrations of some
drugs.Can reduce P-450 by ~45%
Clinically: 1 case report of a 40 y/o woman on 80mg Simvastatin, daily exercise,
skydiving, and eating 1 grapefruit/day x 2 weeks
Use Pravstatin or rosuvastatin
Nutrit Journal 2007; 6:33Am Fam Phys 2006; 74:605
Why be on a Statin???Meta Analysis of 65,000 “intermediate to high risk individuals without history of CVD”
and Statin use and All Cause Mortality
“Use of statins in this high risk population was NOT associated with a statistically
significant reduction in All Cause Mortality”
Arch Intern Med 2010: 170(12): 1024
Warfarin and FoodHigh vitamin K intake can ↓effectiveness of
warfarinLarge amounts: ~14 oz of high Vit. K vegetablesTypical servings (4 oz) have little impact on INR.2005 Dietary Guidelines for Americans
recommends: 3 cups/week of dark-green vegetables (contain
~100-570 microg/serving) of vitamin K1. Nutr Rev. 2005 Mar;63(3):91-7.
Cranberry Juice: Ancedotal reports of interaction“Moderate consumption does not affect
anticoagulation”Am J Med 2010 123(5): 384
9. AHRQ: Update on PreventionGradeA. Folic Acid for Pregnancy: 0.4-0.8 mg/day
B. Mammography (50-74) BiennialB. Obesity: start Age 6 YearsB. Screen Adolescents for Depression
C. Mammography < 50 yearsI. Screening for Hyperbilirubinemia for
infants
www.ahrq.gov
Summing the data
Man screened is 48 times more likely to be harmed than saved at 9 years after diagnosis;
Harms: Impotence, Incontinence, mental anguish, and “even death”
Screening doubles risk of Dx but does not significantly decrease risk of dying
1985: 8.7% risk of Dx; 2.5% risk of death2005: 17% risk of Dx; 3% risk of deathIs it really worth it?
Boyle & Brawley Conclusion“Testing has been based on blind faith in early
detection as opposed to being based on evidence of a decrease mortality”
“Prostate Cancer screening and treatment of early disease is also a profitable industry”
“If we are to stem the spiraling costs of health care, we must move toward the use of evidence based, rather
than faith based or profit based practice of medicine.”“The collective data clearly cannot justify mass screening and indeed appear to justify support for a
recommendation against mass screening.”“Shared decision making.. should include discussion of
the quantified risks and benefits.”CA: 59 (4): 215 - 275
