History – Sexual History
In young adults, adolescents Check for STD risk factors Promiscuity Unprotected sexual intercourse and history of venereal infection Individuals should receive screening about safe sex practices and benefits of barrier-protection contraception ? MSM Women < 25 years should undergo screening for chlamydial infection Periodic HIV testing and syphilis screening should be offered to those at risk
5
History -Depression Screening
SIG E CAPS Sleep, Interest, Guilt, Energy, Concentration, Appetite, Affect, Psychomotor agitation, Suicide Two questions: "Over the past two weeks, have you felt down, depressed, or hopeless?" "Over the past two weeks, have you felt little interest or pleasure in doing things?"

History – Tobacco Use In the year 2000, smoking was attributed to 5 million premature deaths worldwide In the U.S., smoking is attributed to 400,000 deaths a year Most deaths due to CAD, COPD, Lung cancer The incidence of cigarette smoking is increasing worldwide – estimated > 5 trillion cigarettes smoked annually However, prevalence in US is DECREASING Annual cost of smoking in US is >90 billion dollars a year
8
Smoking Cessation The 5 “A’s” for smoking cessation
Ask: Systematically identify all tobacco users at every visit Advise: Strongly urge all tobacco users to quit Assess: Determine a patient’s willingness to attempt to quit Assist: Aid the patient in quitting. Includes counseling, pharmacotherapy, social support Arrange: Schedule follow-up contact.
9
Smoking Cessation Pharmacotherapy Nicotine Replacement
Design to ameliorate symptoms of nicotine withdrawal: anxiety, dysphoria or depressive symptoms, insomnia, increased appetite/weight gain, Includes: Polacrilax (gum) – increases quiting 2-fold Transdermal (patches) – delivers 40-50% of what a smoker at 1 ½ packs a day receives Nasal Spray – has increased tendency for prolonged nicotine dependence Inhaler – caution: may cause bronchospasm
10
Smoking Cessation Pharmacotherapy (cont.) Bupropion (Zyban)
Enhance noradrenergic, dopaminergic function Also used as an anti-depressant (Wellbutrin) Has been shown to significantly increase rate of smoking cessation (especially when used in combination with nicotine replacement). Caution in anorexic/bulemics (increased rate of seizures) Varenicline Is a partial agonist of nicotine acetylcholine receptor Has been shown to increase rate of quitting (may even be better than bupropion)
11
Smoking Cessation Every tobacco user should be offered counseling and nicotine replacement or other pharmacotherapy at every visit. Counseling should focus on: Establishing a quit date Emphasizing abstinence Using other family members Avoiding alcohol and other drugs. Only possible exceptions… Ulcerative Colitis – quitting smoking associated with UC exacerbations. Schizophrenia – those who smoke have better attention and memory
12
Routine Physical Examination
Blood Pressure Monitor every 2 years Goal Blood pressure: 140/90 in most patients 130/80 in patients with Diabetes or Renal Disease Should be measured on 3 separate occassions before diagnosing hypertension. JNC 7 Guidelines: Category Systolic Blood Pressure (mmHg) Diastolic Blood Pressure mmHG Normal <120 < 80 Prehypertension 80-89 Stage 1 Hypertension 90-99 Stage 2 Hypertension ≥160 ≥100
13
Routine Physical Examination
Height/Weight Periodically Body Mass Index BMI = body weight (in kg) ÷ stature (height, in meters) squared If > 30, should receive obesity counseling Healthy diet, with emphasis on limited intake of saturated fat and adequate intake of fruits, vegetables and whole grains Regular physical activity
14
Routine Labs Lipid profile Glucose
Check Fasting lipid profile in patients 20 years or older. If normal, check every 5 years. Glucose Begin at age 45 years (or earlier if cardiac risk factors, hyperplipidemia, family history) Diabetes Mellitus Definition: Fasting glucose ≥ 126 on two separate occasions Random glucose ≥ 200 on two occasions (with symptoms of diabetes
15
Routine Labs (cont.) TSH
Controversial whether or not to check regularly Some guidelines recommend periodic checking in : Postmenopausal women Postpartum women Diabetes Down’s Syndrome Elderly
16
Additional Screening Exams
Osteoporosis Bone mineral density exam (DEXA scan) Women age ≥ 65 years At-risk women ages 60-64/ At-risk men Risk factors include: prolonged hyperthyroidism, celiac sprue, anorexia nervosa, hypogonadism, early menopause, history of androgen-deprivation, long-term corticosteroid therapy, a family history of osteoporosis, low body weight, personal history of fracture. Calcium/Vitamin D supplementation Start calcium at age 30
17
Additional Screening Exams
Abdominal Aortic Aneurysm Men aged years of age who have ever smoked One time screening for abdominal aortic aneurysm by ultrasound
18
Special Pregnancy Recommendations
Folic acid supplementation In all women beginning at preconception and continuing until pregnancy HIV testing Recommended in all pregnant women
19
Cancer Screening Cervical Cancer Pap Smear
Beginning when patient becomes sexually active until age 65 (or until total hysterectomy) At least every 3 years. Insufficient evidence to screen routinely for human papillomavirus (HPV) HPV-DNA testing as follow-up if low-grade atypia or other abnormalities found..
20
Cancer Screening Breast Cancer Mammogram Breast exam
Once every 1 to 2 years age years Annual mammogram for age ≥ 50 Breast exam Either performed by patient or provider, has not been found to have any effect on outcome.
21
Cancer Screening Colon Cancer Beginning at age ≥ 50
Colonoscopy, flexible sigmoidoscopy, fecal occult blood testing, barium enema used alone or in combination are equally effective. If family history of colon cancer in first degree relative, first colonoscopy 10 years prior to his/her age at diagnosis.
22
Cancer Screening – not yet routinely recommended
Prostate Cancer USPSTF has not found evidence supporting the routine use of PSA. Skin Cancer Routine screening for skin cancer using a total body skin exam not recommended. Ovarian Cancer Does not recommend vaginal ultrasound or CA-125 measurement Lung Cancer No established guidelines yet for the use of screening CT of the chest
23
Immunizations Influenza Vaccine Yearly for all adults ≥ 65 years
Younger adults with risk factors CHD, COPD, asthma, Diabetes, renal dysfunction, hemoglobinopathies, immunosuppression Pregnancy Occupational risk (health care workers, employees of long-term care facilities)

Let’s try a few cases… A 46-year old female comes to your office for a physical examination. She has no history of medical problems, but has not been to a doctor in 5 years. She stopped having periods 2 years ago. She also admits to a broken wrist 9 months ago, for which she wore a cast for 8 weeks. She has a family history of hypertension in her mother, and colon cancer in her father at age 55. She denies any tobacco, alcohol use. States her moods been “great” and she and her husband have been taking a yoga class together.

Case #1 Physical Exam: 142/85, 72, Ht: 4’ 11” Wt: 209#
Gen: Alert, oriented, in NAD CV: RRR Resp: LCTA bilaterally Abd: soft, nontender, NABS Ext.: No lower extremity edema Skin: multiple ecchymoses on proximal arms and back in various stages of healing.
31
Case # 1 What additional lifestyle screening do you want to perform in this patient? What labs would you order? What screening studies might you perform? What immunizations, if any, might you give? Would you automatically recommend any medications in this patient?
32
Case #2 A 69-year old male with a history of hypertension presents for follow-up. He states that he’s been very good about his preventative care – he had a colonoscopy last year, and got his pneumonia shot and flu shots this year. He does continue to smoke 2 packs a day, and his wife whispers that the number of tequila shots he takes at night seem a bit excessive.
33
Case #2 What additional lifestyle screening questions do you want to ask? What labs do you want to make sure are up to date in this patient? What other screening studies, if any, do you want to perform?
34
Case # 3 A 24-year old female comes to your clinic for a physical exam. She hasn’t seen a doctor in 4 years. She states that she think she may want to get pregnant soon, but isn’t sure which of her boyfriends is going to be the lucky man. She admits to smoking a couple of cigarettes a day, and has a few beers during the week. She states that her mother didn’t believe in shots growing up, so she’s never gotten any.
35
Case # 3 What testing do you want to perform in this patient?
What medications should she be taking? What immunizations should she receive?
