A 23-year-old woman is evaluated for chronic migraine headaches. She is experiencing five migraine headaches per month, which are negatively affecting her quality of life. She wants to start a prophylactic medication regimen but has responded poorly to β-blockers and amitriptyline in the past. She wonders whether gabapentin medication is likely to help her. The remainder of the patient's history and physical examination is normal. Which of the following sources of information is most likely to provide reliable information for answering this patient's clinical question? A Randomized clinical trial B Case report C Case-controlled studies D Systematic review E Drug information inserts

Clinical Studies • RCT: Randomization, blinding, and placebo maximize validity. • Limitations: Generalizability, feasibility. Ex: Pap Smear • Cohort studies • Large with long follow-up. Try to control for patient variables. • Case–control : Hypothesis-Generating • Systematic Reviews: Inclusion criteria. Combine effects to maximize power.
A 53-year-old man with chronic obstructive pulmonary disease and cor pulmonale has recently transferred his medical care to the city in which his daughter lives. His current medications include albuterol and corticosteroid inhalers, hydrochlorothiazide, digoxin, and supplemental oxygen. After considering whether to discontinue the digoxin, the physician reads a systematic review on the use of digoxin in heart failure. Which of the following best guards against the inclusion of biased information in the review? A Calculating the number needed to harm B Calculating the number needed to treat C Specifying criteria for selection of reviewed articles D Grading the quality of evidence

A 54-year-old woman is evaluated for a 4-day history of an acute headache that has been gradually worsening and is located diffusely on the left side of her head. The patient is nauseous but does not have photophobia, fever, chills, history of tick exposures, trauma, stiff neck, muscle weakness, parasthesias, or bowel or bladder problems. She awakens with the headache and it gradually worsens during the day, and she experiences slight relief with acetaminophen and ibuprofen. She has a family history of migraines and, as a teenager and in her mid-30s, had a few migraine headaches that were more severe than her current episode and were associated with photophobia and severe fatigue. However, since those episodes, she had been headache free until now. Her medical history includes hypertension, diabetes mellitus, breast cancer for which she underwent lumpectomy 4 years ago, and osteoarthritis. Current medications include atenolol, metformin, tamoxifen, and enteric-coated aspirin. On physical examination, the patient appears to be in mild distress, but vital signs are normal. The neurologic evaluation is significant for decreased vibratory and monofilament perception in the bilateral lower extremities in a stocking distribution.

A 44-year-old obese man is evaluated at a follow-up of chronic medical problems. He has been trying to follow a restricted-calorie Mediterranean-style diet for the past year after being unable to comply with a low-carbohydrate, high-protein diet the year before. He has been on sibutramine to lose weight for the past 2 years and has attended a medically supervised weight loss clinic. The patient initially lost 4.5 kg (10 lb) but gained 2.3 kg (5 lb) back.

On physical examination, temperature is normal, blood pressure is 144/78 mm Hg, pulse rate is 70/min, and respiration rate is 14/min. BMI is 43. Hemoglobin A1c is 8.2%, and random plasma glucose is 186 mg/dL (10.32 mmol/L). Laboratory results, including complete blood count, hepatic enzymes, and serum chemistry studies, are otherwise normal.
Which of the following is the most appropriate management option for this patient? A . Bariatric surgery B. Begin a very-low-calorie diet (800 kcal/d) C. Continue sibutramine D. Discontinue sibutramine and prescribe orlistat
