In 1996, approximately one quarter of the AIDS prevention budget of the CDC was allocated to HIV testing, predominantly for low-risk populations.1 It was their single biggest HIV prevention expenditure.

When should buried stitches be used in closing a laceration? Which tools are best for removing a popcorn kernel lodged in a 2-year-old's nose? How do you determine the appropriate site for a shoulder injection? These are just some of the questions that will be answered in our new feature, "Primary Care Procedures: A Photo Guide," which launches in this issue on page 1035.

A comatose 82-year-old woman is brought to the emergency department. Her husband reports that after dinner she began to have difficulty in speaking, lost consciousness, and fell to the floor. He tried to rouse her, but was unsuccessful and called for an ambulance.

In a previously published Practical Pointer (CONSULTANT, August 2005), D. Brady Pregerson, MD, of Los Angeles proposed a method for tightening loose stitches after the clinician has finished suturing.

At the end of her Guest Commentary, "The Virtual Patient" (CONSULTANT, July 2007), Dr Faith Fitzgerald asks: "How shall my students experience the things that cannot be taught but only learned through the sometimes inconvenient, potentially time-consuming, emotionally disquieting, and generally non-remunerative interactions with real patients?"

When you need to jot down the name of a medicine, condition, or specialist for a patient and you're in a hurry, just grab a tongue depressor.

Within the past 7 years, the incidence of methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile infections has significantly increased. Risk factors for MRSA infection include previous antibiotic therapy and living arrangements such as prisons or military barracks that involve close, frequent contact with infected persons. Treat stable patients with MRSA skin infections with oral antibiotics in addition to incision and drainage; hospitalization and intravenous antibiotics are recommended for patients whose condition is unstable or who are unlikely to adhere to an oral regimen. A new strain of C difficile, BI/NAP1, has been associated with recurrent infection; more severe disease that mandates urgent colectomy; and dramatically higher mortality in vulnerable populations, such as older adults. Although oral metronidazole has been the mainstay of treatment of C difficile infection, oral vancomycin may be slightly more effective in patients with severe disease.

An 89-year-old man reported that this lesion began developing on his left forearm 11 days earlier. It is a keratoacanthoma, a rapidly growing but benign neoplasm that occurs predominantly on the extensor surfaces of the hands and forearms of white men over age 50.

Although many lacerations are treated in the emergency department, primary care clinicians still see their share of such wounds. Most lacerations are incurred on the face and head (as a result of falls or altercations) or on the hand or lower arm (caused by tools, broken glass, or other sharp objects).

SALT LAKE CITY -- Forecasts that physician-assisted suicide and euthanasia would be practiced disproportionately on vulnerable groups, such as the poor, the elderly, and women, did not prove accurate, according to researchers here.
