Cutaneous manifestations are common in patients infected with HIV and tend to be more frequent as immunodeficiency progresses. It remains, however, unclear which or how many with HIV-1 infection will develop skin disease. This paper presents and describes the commonly reported skin diseases occurring in people with HIV-1 infection. Observed infections include herpes zoster, herpes simplex, chancroid, syphilis, condylomata acuminata, oral hairy leukoplakia, molluscum contagiosum, candidiasis, bacterial infections, dermatophytosis, and scabies. Noninfective conditions such as pruritic papular eruption, seborrhoeic dermatitis, psoriasis, and others may also present. Regarding disease etiology, a transient maculopapular rash may present in the initial stage of HIV infection. Seborrhoeic dermatitis, persistent genital ulcer disease, pruritic papular eruption, and/or a variety of scaling dermatoses may then be observed during the otherwise asymptomatic phase. Kaposi's sarcoma is the most frequent skin tumor associated with HIV disease. It is also observed that skin manifestations of adverse reactions to drugs occur more frequently in patients with HIV disease than in immunocompetent patients. In closing, most skin diseases associated with HIV disease respond well to standard treatment regimens. Relapses and/or recurrences are, however, frequent among these patients.

This retrospective case review sought to report the findings of a health screening of 100 international adoptees. Included were the 1st 100 children who attended the Outpatient Inter-Country Adoption Clinic at the Royal Children's Hospital in Melbourne. A medical history was taken and a thorough physical examination and series of screening investigations were performed on all children. The children range in age from 2 months-16 years (median=5 months; mean=2.8 years). The countries most represented were Korea with 36 children and India with 21. 30 children fell below the 3rd Australian centile for both height and weight. Abnormalities on physical examination included hepatosplenomegaly (13 children), scabies (6), and severe dental caries (6). Parasitic infestation of the stools was found in 23 children, a positive Mantoux test result in 9 (3 with active tuberculosis), anemia in 12, elevated hepatic transaminase levels in 9, and positive hepatitis B surface antigen and e antigen in 2. I child had acquired syphilis. Screening for human immunodeficiency virus antibody gave negative results in all children. These international adoptees constitute a special pediatric subgroup which require assessment and screening as soon as possible after arrival in their adoptive country.

Crusted (Norwegian) scabies, a rare variant of ordinary scabies, is a highly contagious infection in which the skin is infested with thousands to millions of mites. The infection is frequently overlooked because of its atypical presentations. Patients with cognitive deficiency or an immunodeficiency disorder (including immunosuppressive therapy) are predisposed to developing crusted scabies. The infection often presents as generalized dermatitis with crusted hyperkeratosis on the palms and soles. Diagnosis is made by examining skin scrapings from the crusted lesions. Lindane is the scabicide most widely used in the treatment of crusted scabies. Eradication frequently requires repeated applications, and care must be taken to avoid lindane toxicity. Permethrin cream is as efficacious as lindane in the treatment of ordinary scabies. Because of its wider margin of safety, permethrin may become the preferred treatment for crusted scabies.

A case of crusted (Norwegian) scabies in a patient with the acquired immunodeficiency syndrome (AIDS) is described and seven previous reports of this association are reviewed. Injury to epidermal Langerhans' cells by the human immunodeficiency virus or cytotoxic cells may explain the appearance of this unusual form of scabies in patients with AIDS.

Lice and mites are highly contagious obligate parasites of humans and are spread by close, direct contact. Head, body, and pubic lice produce severely pruritic eruptions in their respective locations. Diagnosis is readily made by finding lice or nits on hair shafts, except in the case of body lice, which are found on the seams of clothing. Scabies often presents as a more generalized pruritic rash. Diagnosis is confirmed by finding the mite in a characteristic skin burrow. Crusted (Norwegian) scabies, a rare variant consisting of infestation by thousands of mites, occurs in patients with neurologic or immunodeficiency disorders. Secondary bacterial infections and eczematous changes may complicate both pediculosis and scabies. Infestations are easily treated with use of an appropriate pediculicide or scabicide and environmental-control measures.

In the human immunodeficiency virus (HIV) infected patient, skin infections caused by S aureus are extremely common. Impetigo, ecthyma, and folliculitis are all seen. Recurrences are common due to a nasal carriage rate of 50%. Dermatophytosis usually manifests as tinea pedis or unguium and is caused by Trichophyton rubrum. Oral candidiasis may be the initial evidence of HIV infection, and is predictive of more rapid progression to acquired immune deficiency syndrome (AIDS). Topical agents are usually effective for oral lesions, but involvement of the esophagus requires oral imidazole therapy. Systemic fungal infections are most commonly caused by cryptococcosis or histoplasmosis. The finding of either of these infectious agents in the skin is pathognomonic of disseminated infection. Cryptococcus presents as umbilicated papules resembling molluscum or as large ulcerations. Histoplasmosis has no specific cutaneous morphology. Scabies is very common in HIV-infected persons, and once the helper T-cell count is less than 200, it may present atypically. Permethrin is the recommended treatment in this setting.

Scabies is a common infestation for patients of all ages throughout the world. One of the standard therapies for scabies is 1% lindane lotion. Lindane has been associated with neurotoxic reactions, specifically seizures. We describe a case of a middle-aged adult man with human immunodeficiency virus (HIV) infection who was found to have typical scabies and was treated with a single topical application of lindane. Two hours after the application, the patient experienced a new-onset generalized seizure. We believe that the triad of HIV infection, medications that reduce seizure thresholds, and percutaneous absorption factors, in the aggregate, induced the seizure. We believe that lindane should not be prescribed for patients with HIV infection.

Bacillary angiomatosis (BA) presents most commonly as a cutaneous disease and is caused by two organisms. Bartonella (Rochalimaea) henselae and Bartonella (Rochalimaea) quintana. Biopsy confirmation of cutaneous BA is essential because lesions can mimic nodular Kaposi's sarcoma in appearance. Although the vast majority of human immunodeficiency virus (HIV)-infected patients with BA have CD4 lymphocyte counts of less than 100 cells per mm3, the disease responds well to antimicrobial therapy. Staphylococcus aureus is the most common bacterial skin pathogen affecting HIV-infected patients. The prevalence of skin disease due to S. aureus may be explained by high nasal carriage rates for the organism ( > or = 50%) and altered immune function in conjunction with an impaired cutaneous barrier. Herpes simplex virus causes mucocutaneous disease early in the course HIV infection and ulcerative lesions at any site in advanced HIV infection. Herpes zoster is common early in the course of HIV infection; recurrent and disseminated herpes zoster infections are characteristic of patients with advanced HIV disease. Acyclovir resistance is usually seen in patients with large, untreated, ulcerative lesions of herpes simplex virus and in patients with chronic, verrucous lesions of varicella-zoster virus. Cutaneous cryptococcosis, histoplasmosis, and coccidiomycosis are markers of disseminated disease and require biopsy confirmation. Scabies is easily diagnosed but may be atypical in presentation and difficult to eradicate in advanced HIV disease.

The addition of permethrin as a scabicide with low toxicity adds significantly to our therapeutic options for typical and special forms of scabies. Detailed specific management suggestions, as well as a scabies instruction sheet, are included. The management of crusted (Norwegian) scabies and scabies in human immunodeficiency virus-acquired immune deficiency syndrome (HIV/AIDS) is more difficult and may require, particularly in those intensely immunosuppressed, repeated treatment with scabicides and sometimes sequential use of several agents. Tolerance (resistance) to lindane was suggested in Central America but also in South America, Haiti, Egypt, and in clusters in the United States.

Crusted (Norwegian) scabies in AIDS patients can be manifested in both typical and atypical forms. Although the classic, hyperkeratotic, nonpruritic lesions are most common, reported cases have ranged in spectrum from crusting with pruritus to a pruritic, papular dermatitis to those resembling Darier's disease or psoriasis. We report two additional cases of crusted scabies in AIDS patients, one with typical crusted, hyperkeratotic though pruritic lesions and one with severe pruritus and rare papules, initially misdiagnosed as "pruritus of AIDS." Because of the extremely contagious nature of crusted scabies, as well as its potential for complete cure with appropriate therapy, a high degree of suspicion for this disorder should be maintained in AIDS patients, even when the lesions do not have the classical appearance. The discovery of crusted scabies, whether in its common or its atypical form should prompt testing for the human immunodeficiency virus (HIV).
