Now that baby boomers have reached the age of Medicare eligibility, joint replacements are on the rise. Because patients who undergo hip or knee arthroplasty require anticoagulation, primary care physicians have a key role in the care of these persons- before as well as after surgery.

It can be difficult to determine whether unusual, paroxysmal behavior represents a seizure or a nonepileptic event. Patients with sudden flailing movements or unresponsive staring may, in fact, be experiencing psychogenic events. Other types of pathological spells, such as syncope and migraine, can also be mistaken for epileptic seizures.

African Kaposi Sarcoma

A 46-year-old man with AIDS (CD4+ cell count, 150/μL) presented with a painful nodular lesion on the plantar surface of his right foot. The lesion had appeared 1 month earlier as a painless, 1-cm, raised, reddish purple nodule and had progressively enlarged to 5 cm. Six months earlier, the patient had cryosurgery to remove a similar, larger lesion on the posterior aspect of his right midcalf.

A 49-year-old man presented to the emergency department (ED) with substernal chest pain that had started an hour earlier.

After a family argument, an 83-year-old woman experienced chest pain, a "racing heart," and a choking sensation and was brought to the emergency department. The chest pain lasted 10 to 15 minutes; was sharp, substernal, and nonradiating; and was associated with dyspnea and a bout of emesis. A sublingual nitroglycerin tablet partially alleviated the pain, but the patient felt syncopal. Her symptoms persisted despite the administration of supplemental oxygen and a second sublingual nitroglycerin tablet. The patient had a history of gastroesophageal reflux disease, allergic rhinitis, and osteoarthritis. Her oral medications included esomeprazole (40 mg/d), aspirin (81 mg/d), and fluticasone nasal spray. She had discontinued valdecoxib 3 weeks earlier.

I recommend obtaining an ECG in any older patient whose heart rate is more than 100 beats per minute on several occasions. Although it is easy to chalk up such findings to "nerves," "white coat phenomenon," or a morning cup of coffee, I have caught a few cases of asymptomatic atrial fibrillation this way.

How effective is upper airway surgery in treating obstructive sleep apnea? The fallout from the growing obesity epidemic includes obstructive sleep apnea (OSA) syndrome. Although OSA may be considered a "specialty disease" (managed by pulmonologists, sleep specialists, otolaryngologists, and bariatric surgeons), the primary care physician bears the brunt of providing ongoing care.
