Case 1:

JB is a 75 year old male who has had long-standing atrial fibrillation. His other medical problems include hypertension and diet-controlled diabetes mellitus. He has been prescribed Warfarin for stroke-prevention and has been well controlled on this medication for 5 years. He has always been strictly adherent to his medication regimen. He presents to your office for an urgent visit, telling you that he “gets bruised if I just touch something”. He has not complained of this in the past.

On chart review you noted that his medication regimen has been unchanged for nearly 2 years:

1. Warfarin, 5 mg orally at bedtime
2. HCTZ, 25 mg orally each day

On physical examination, you note that the patient has some ecchymoses on his forearms bilaterally. Further history taking elicits that he has noted significant bleeding of his gums during tooth brushing. You question JB closely regarding his medication regimen. He denies any changes. Then, you remember that JB complained of some mild bilateral knee joint pain during his last scheduled visit, as well as symptoms of an upper respiratory tract infection.
