Vitiligo. These are more illustrations of fairly extensive cases of vitiligo. The condition tends to progress and may even become universal. A variety of treatment modalities are commonly employed, with varying degrees of success. The patient and family should be made aware of the sophisticated cover-up cosmetics that are now available. The use of broad-spectrum sunscreen lotions during the summer months minimizes the con- trast between normal and involved skin. For some patients, the application of topical corticosteroids alone or with brief natural sunlight exposure early in the course of the disease may induce repigmentation. Narrowband UUB is also an effective treatment. Varying combinations of topical or oral psoralens and ultraviolet A light (PUVA) are used in the treatment of vitiligo.
Varicella Chickenpox. Varicella Chickenpox is caused by a virus of the herpes group. The disease is highly contagious and is spread by droplet or direct contact. The incubation period for chickenpox ranges from 11 to 21 days. Prodromal symptoms consist of low-grade fever, headache, anorexia, and malaise. On the following day, the characteristic rash begins to appear. The lesions evolve from erythematous macules to form small papules. Quickly, a clear vesicle arises on this erythematous base. The classic lesion of chickenpox has been poetically described as a “dewdrop on a rose petal.” Over the next several days, the vesicles rupture and then crust. The rash begins on the chest and back and spreads centrifugally to involve the face, scalp, and the extremities. New lesions of chickenpox arise in crops over a period of several days.
