Hypertension Treatment
A 25-year-old woman is evaluated in the urgent care department because of the recent onset of heel pain that is especially severe when jogging. She has been taking ibuprofen for the past 7 days. Her only additional medications are a low-dose oral contraceptive that she has been taking for the past 5 years and a multivitamin. She does not smoke cigarettes. She is otherwise healthy and has no history of hypertension.
On physical examination, blood pressure is 162/102 mm Hg and pulse rate is 90/min. BMI is 24. The remainder of the examination, including cardiopulmonary, funduscopic, and neurologic examinations, is normal.
Laboratory studies, including blood urea nitrogen, serum creatinine, and urinalysis, are normal.

A 63-year-old man is evaluated during a follow-up appointment. One month ago, he had a transient ischemic attack. Carotid ultrasound revealed a 60% left internal carotid artery stenosis, and transthoracic echocardiogram revealed left ventricular hypertrophy. He is currently asymptomatic. He has hypertension and quit smoking 10 years ago. He has no history of coronary artery disease and no family history of premature coronary artery disease. Current medications are hydrochlorothiazide and aspirin. An LDL cholesterol level 6 months ago was 138 mg/dL (3.57 mmol/L), and he has been compliant with recommended lifestyle modifications, including diet and exercise. On physical examination, blood pressure is 132/84 mm Hg. There are no focal neurologic abnormalities. Fasting lipid levels are as follows: total cholesterol 206, HDL 50, LDL 132, triglycerides 144

If myalgia present and statin must be used, add coenzyme Q10 to help resolve symptoms.
A 51-year-old woman is evaluated during a routine physical examination. She has no history of hypertension and has never used tobacco. There is no family history of heart disease. Her only medication is daily oral conjugated estrogens combined with medroxyprogesterone acetate for intolerable hot flushes. Physical examination is normal. BMI is 31.

A 56-year-old woman is evaluated for hot flushes that have been interfering with her sleep and causing discomfort while at work.

Menopause
• Dx: Clinical. – Only check FSH if occurring in younger patients or
unsure of diagnosis• Vasomotor symptoms:– Tx: low dose estrogen (add progesterone if still has
uterus); SSRI, clonidine, venlafaxine, gabapentin• Vaginal dryness – Tx: estrogen cream
Estrogen Estrogen + Progesterone
Breast Cancer
Endometrial Cancer
Ovarian Cancer
Colorectal Cancer

VTE, Heart Disease, Stroke
Hormone Replacement Therapy
**Estrogen alone causes endometrial hyperplasia and increase risk of endometrial cancer- must use combination estrogen progesterone in women with a uterus
HRT is NOT recommended for prevention of chronic disease after menopause.
AVOID HRT in smokers, CAD, history of breast cancer, high risk of thromboembolic disease, undiagnosed vaginal bleeding or who are well past menopause.
A 40-year-old woman presents with a history of heavy painless menstrual bleeding for the past 4 days. Her last period was 20 days ago, but before that, her periods had become more irregular over the previous 2 years, with lighter than usual bleeding. She has been sexually active with her husband, but had a tubal ligation after the birth of her fourth child 6 years ago.
On physical examination, the vital signs are normal. There is no evidence of hypovolemia or conjunctival pallor. The skin examination is negative for ecchymoses and petechiae. The bimanual pelvic examination reveals a nontender, normal-sized, and regular uterus. Speculum examination reveals a normal-appearing cervix with dark blood in the cervical os but no other abnormalities. A Pap smear is performed. A urine pregnancy test is negative.

A 24-year-old woman is evaluated for a 2-week history of vaginal itch and a discharge. She has tried douching and an over-the-counter vaginal cream without success. She and her partner have been together for 2 years, and they have been considering getting pregnant. Current medications are a vaginal benzocaine cream and an oral contraceptive. On speculum examination, she has a cloudy, thin discharge coating the vaginal walls with a fishy odor to the discharge when potassium hydroxide is applied. The cervix appears normal. A bimanual examination is normal. The vaginal discharge has a pH level of 5.0. Clue cells are seen on wet mount. Which of the following is the most appropriate management option for this patient?

Vaginitis
Contraception• OCP:
– Increased risk of MI, but reduced estrogen has improved this– May increase risk of hypertension– Increased risk of stroke (small)– Increased risk of venous thromboembolic disease **especially for smokers– Reduced risk of ovarian and endometrial cancer (opposite of HRT)– Increased risk of cervical cancer– Conflicting data with breast cancer
• IUDs: increase risk of PID• Male and Female condoms: help with prevention of STDs (not HIV)• Sterilization: in women who become pregnant with tubal ligations, rate of ectopic
pregnancies is high• Emergency contraception:
– Oral levonorgestel- take 2 doses within 5 days of intercourse– Oral mifepristone- only approved for termination of pregnancy– Copper IUD- most effective; insert within 5 days of intercourse and can be kept in place
for up to 10 years
A 49-year-old woman is evaluated after noticing a small lump in her right breast 3 weeks ago. It is painless and has not changed in size. She has no other pertinent medical history and did not use oral contraceptives. She had menarche at age 12 years and is still menstruating. Her last menstrual period was 2 weeks ago. She has two children, the first at age 25 years and the second at age 30 years. Her mother had breast cancer at age 55 years; there is no other family history of cancer. On physical examination, vital signs are normal. There is a 1.0 cm × 1.5 cm firm, discrete, mobile mass in the upper outer quadrant of the right breast. There is no lymphadenopathy or other abnormalities on examination. A mammogram done 18 months ago was normal.

Evaluation of a Breast Mass
A 64-year-old man is evaluated for a 1-year history of slow urinary stream, urinary hesitancy, and postvoid dribbling. Previously, he got up once a night to urinate, but in the past 2 months, his nocturia has increased to three times per night. His American Urological Association prostate symptom score is 9 (score >7 indicates moderately severe symptoms).
On physical examination, temperature is normal, blood pressure is 146/80 mm Hg, and pulse rate is 74/min. Abdominal examination is normal without tenderness or masses or evidence of a distended bladder. Digital rectal examination reveals a slightly enlarged prostate without discrete nodules or tenderness. Routine laboratory studies and urinalysis are normal. Prostate-specific antigen level is 1.0 ng/mL (1.0 µg/L). A urine culture shows no growth.

A 19-year-old man is evaluated for increasing pain in the left testicular region for 2 days. It is tender when he palpates the scrotum or moves. He has had some mild dysuria but has not noted any urethral discharge. He is taking no medications, has not had any procedures or trauma to the region, and has no history of similar symptoms. He feels generally ill today with some mild nausea and a poor appetite but no vomiting.
On physical examination, temperature is 38.4 °C (101.2 °F) and other vital signs are normal. There is mild erythema overlying the left side of the scrotum. There is no edema of the scrotum. An area superior and posterior to the left testicle is moderately tender to palpation, with mild fullness and bogginess. The left testicle is nontender, similar in size to the right testicle, and sits lower in the scrotum than the right testicle. The cremasteric reflex is intact bilaterally. The penis and right testicle are normal.

He experiences occasional exertional chest pain after quickly walking six to eight blocks or three flights of stairs, but has no chest pain at rest or with usual activities and no dyspnea. This symptom has been stable for the past few years, and he has not used any nitroglycerin for it. He has hypertension. He has no history of myocardial infarction or diabetes mellitus. He does not smoke or drink alcohol. Current medications are aspirin, metoprolol, atorvastatin, and enalapril.
