RESUMO
Cocaine has been associated with a number of cutaneous manifestations, and most reports in the literature have described cocaine-induced vasculitis. However, not all reactive patterns secondary to cocaine use are vasculitic in nature. Recently, there has been a disturbing trend of "cutting" cocaine with pharmacologically active substances, the most common being levamisole. This agent is known to cause serious adverse effects including agranulocytosis and cutaneous eruptions. The authors describe a 52-year-old woman who acutely developed an extensive bullous rash in the lower extremities after she snorted cocaine. The clinical, hematological and serological findings were suggestive of levamisole-induced vasculitis, but histopathology of the skin showed thrombogenic vasculopathy with no inflammatory infiltrate. A skin biopsy is an essential component in the diagnosis of cocaine-related syndromes and can aid in the distinction from true autoimmune vasculitis.

We report a case of disseminated human papillomavirus infection that developed in a patient while receiving efalizumab for the treatment of psoriasis. This infection progressed for several months after efalizumab treatment had been stopped. All human papillomavirus lesions completely resolved after 10 weeks of therapy with a combination of pegylated interferon and ribavirin.

In addition to its U.S. Food and Drug Administration (FDA) approved conditions, immune globulin intravenous (IGIV) is now being used to treat a vast array of autoimmune disorders. Some of the reasons for this overall increase in the use of IGIV include its effectiveness and safety. Despite many years of safe use, side effects and adverse reactions still occur. Common and mild side effects associated with IGIV include: headache, malaise, nausea, low-grade fever, urticaria, arthralgias, and myalgia. These symptoms typically resolve within a few days after their onset. Although rare, the serious and potentially fatal side effects include: anaphylactic reactions, aseptic meningitis, acute renal failure, stroke, myocardial infarction, and other thrombotic complications. Many of these side effects have occurred in patients who have significant, underlying risk factors for the development of the event. Thus, it is vitally important that a thorough and comprehensive medical evaluation be performed on every patient who is being evaluated for potential IGIV therapy. This evaluation can, to some extent, significantly minimize the risk of these side effects. Careful, constant, and close monitoring by trained personnel during the infusion can also result in early detection of such events. Physicians should thoroughly discuss the risks and benefits of IGIV with patients who are being considered for this therapy.
