Physical changes that occur in aging skin (eg, dryness and thinning) can result in pruritus and cause patients to rub, scratch, and pick at their skin. These activities produce various dermatoses and reactive changes in the skin, such as postinflammatory pigmentary alteration. Lichen simplex chronicus (LSC) develops as a physiological cutaneous response to repetitive scratching or rubbing. First-line treatment consists of topical corticosteroids and application of ice to reduce the sensation of itching. Like LSC, prurigo nodularis results from rubbing and scratching the skin. Treatment is similar; however, intralesional corticosteroids and UV therapy play more of a role because prurigo nodularis is more intensely pruritic than LSC.

What is the role of the primary care practitioner in the care of patients with HIV infection?Although the treatment of human immunodeficiency virus type 1 (HIV-1) infection is usually directed by subspecialists, many patients who are taking highly active antiretroviral therapy (HAART) continue to see their primary care physician.

The Bwindi Forest is also home to more than half of the world’s 650 mountain gorillas.

A documented anti–varicella-zoster virus (VZV) titer is generally accepted as evidence of protection against VZV infection, and a known case of shingles, such as that described in the Photoclinic case of an older man with ophthalmic zoster (Tran KT, Qualm AS, Shannon MA. CONSULTANT, December 2009, page 767), might reasonably be expected to boost anti-VZV titers in the affected patient. Why then would administration of the zoster vaccine be included in this patient’s treatment plan?
