We report the case of a 20-year-old homosexual man with HIV-1 infection presenting with AIDS. An erythemato-squamous, papulo-crustous, non-itching dermatosis of 4 months duration was finally diagnosed as Norwegian scabies in the immunosuppressed. For clinical and epidemiological reasons the high contagiosity of this rare entity requires an appropriate therapy without delay.

Pruritus is usually caused by a primary disorder of the skin, but can also be caused by a systemic disease (Table 1). Some dermatologic conditions that cause pruritus can be inconspicuous or nonspecific (Table 2), while others are usually apparent on physical examination (Table 3). Classification of pruritus as localized (Fig. 1) vs. generalized (Fig. 3) can be helpful in arriving at a correct diagnosis. The history and physical examination are the most important diagnostic tools, though laboratory testing for systemic disease may be necessary. In refractory cases, one should consider occult systemic disease (such as malignancy), psychiatric disease (especially depression), and HIV infection. Subsequent referral to a dermatologist may be indicted. When treatment of the underlying cause of pruritus is not possible, antihistamines and topical agents (menthol, phenol, and/or pramoxine) can be helpful.

A report from Kampala, Uganda, compares the situation in 1991 to the state of chaos 10 years earlier when the regime of Idi Amin had been overthrown by Milton Obote's soldiers with the help of Tanzanian troops. Soldiers went on looting sprees, and 1 victim of their marauding became a 12-year old boy who got shot for refusing to part with his bike. In contrast, in 1991 things were much more peaceful; however, the AIDS epidemic was the new threat. The government radio transmits hourly warnings on HIV. Since President Museveni came to power, economy and security have improved radically. Shops and markets are open until late at night; public transport is reliable, and small scale industry flourished. There would be optimism about the future, if AIDS was not here. There is no doubt that the economy will soon be affected. According to the Kampala blood bank, 40% of the healthy population is already seropositive. In the hospitals the majority of admissions suffer from AIDS with diarrhea and an itching dermatitis; there is more cancer of the cervix and lymphoma; appendicitis is on the increase; and tuberculous lymph nodes are now quite common. Many of these patients have clinical AIDS. The government is frank about the situation and is active in preventive measures and education. Private charities and foreign aid organizations contribute. But the epidemic is so overwhelming, that some Western organizations might soon lose interest owning to meager returns on their efforts. A 6-year-old boy has grossly swollen lymph nodes around his neck, both parotids are painfully swollen, pus pours from the ears. A nonspecific cough and mild diarrhea are also present with an itching and sore herpes zoster on his left chest. the mother is frightened of losing him, and demurs at the hint of AIDS, since for her, AIDS means sexual promiscuity.

The number of people travelling of the tropical countries is in constant progression and today represents about 5% of the population of the developed countries. Mortality is mainly accidental. Morbidity essentially concerns transmissible diseases. Diarrhoeal symptoms occur in 20-55% of travellers, are bacterial in 2 cases out of 3, and can be prevented. Cholera should soon have an efficient oral vaccine. Hepatitis A is frequent in some travellers (2-3%) and can be prevented by vaccination. Hepatitis E is beginning to be observed. Strongyloidiasis can in some cases evolve to serious complications; it may be latent, so should be sought systematically after any visit to the tropics. Most affections on returning to the industrialised world concern paludism of the Plasmodium falciparum type, leading to a still high mortality rate of 400 per year in Europe, while the preventive and curative means available are sufficient. Any fever should therefore be suspected and suitable treatment given. Other causes of fever are acute viral hepatitis, typhoid fever, the arboviroses, and numerous other conditions. Dermatoses represent the third reason for consultation on returning. These mainly concern pruriginous symptoms with filariases and abnormal hosts being evidenced. Furunculous lesions indicate a diagnosis of cutaneous leishmaniosis or myases. Any form of pruritus should suggest a diagnosis of HIV infection, or pruritus should suggest a diagnosis of HIV infection, or particularly trypanosomiasis. The risk of sexually transmissible disease is overall 6-fold higher in tropical travellers; advice before travelling is therefore of paramount importance. Should a seropositive subject travel to the tropics?(ABSTRACT TRUNCATED AT 250 WORDS)

Cutaneous reactions, including acne, pruritus, urticaria, and nail dyschromia, have been associated with zidovudine use. Cutaneous leukocytoclastic vasculitis is characterized by distinctive patterns of dermal perivascular inflammation without visceral involvement. We treated two cases of cutaneous leukocytoclastic vasculitis associated with fever in patients with severe human immunodeficiency virus-related immunodeficiency in which symptoms resolved on withdrawal of zidovudine therapy and recurred after rechallenge with the drug. This unusual hypersensitivity reaction to zidovudine is probably related to the immune dysregulation and the propensity toward allergic phenomena found in human immunodeficiency virus infection.

The papular eruption (PE) associated with human immunodeficiency virus infection, although described as a distinctive clinicopathologic entity, has shown a wide range of histologic findings ranging from eosinophilic folliculitis to granuloma annulare. We examined 48 cases of the PE in order to define the histologic spectrum of these lesions, and to correlate these findings with clinical presentations. The most distinctive clinical features are the frequency of these lesions in this population, the large number of lesions, pruritus, and the chronic nature of the lesions. Histologically, the distinctive features are the prominent perivascular factor XIIIa-positive dermal dendritic cells, atypical vascular proliferation, and dermal fibrosis sometimes associated with diffuse necrobiotic changes.

HIV-positive Patients often suffer from the symptoms of accompanying diseases. Palliative radiation therapy of associated tumors leads to an improvement of the patient's condition. Particularly skin tumors, which give rise to pronounced itching and ulcerating, are eliminated fast and safe by radiation therapy. Between 1984 and 1988, 6 HIV patients with Kaposi's sarcoma at different sites, and one HIV-patient with non-Hodgkin's lymphoma were treated by radiation therapy. Depending on tumor site, photons or fast electrons were used. Cosmetic results were satisfying or even excellent in all patients. With one exception complete local tumor control was obtained. Side effects leading to a peace of treatment did not occur.

To evaluate the consequences of receiving human immunodeficiency virus type 1 (HIV-1)-seropositive blood, 90 HIV-1-seronegative recipients of HIV-1-seropositive blood (case patients) and 90 HIV-1-seronegative recipients of HIV-1-seronegative blood, matched for age, sex, number of transfusions, diagnosis, and severity of illness (controls), were followed for 12 months after transfusion at Mama Yemo Hospital in Kinshasa, Zaire. Of case patients and controls, 72% were children transfused for anemia caused by malaria. Of the 46 case patients case patients alive 6 months after transfusion and for whom HIV-1 serologic results were obtained, 44 (96%) had seroconverted. Significantly more case patients (47%) than controls (16%) died within 1 year after transfusion (P less than .001). In the first 3 months after transfusion, fatigue, diarrhea, fever, cough, pruritus, pallor, oral candidiasis, polyadenopathy, hepatosplenomegaly, and rhinorrhea were observed more often among seroconverters than controls (P less than .04). Six percent of case patients and no controls had developed clinical AIDS after 12 months of follow-up. These findings underscore the urgent need for appropriate HIV screening facilities in transfusion centers worldwide.

Twenty-one immunodeficiency virus 1 (HIV 1)-positive hemophilic patients were treated with Azidothymidine (AZT) for symptomatic HIV infection. The median observation period was 20.5 months. At 25 months the probability of survival was 82%, the probability of progression of disease from CDC III or IV C2 to IV C1 (AIDS) was 20% in patients on continuous AZT treatment and 50% in patients with interruption of treatment. Three patients developed severe leukopenia and 3 patients severe anemia during AZT treatment. In 1 patient a dose-dependent striking increase of transaminases during AZT treatment was observed. In 7 patients treatment was interrupted, in 1 patient because of anemia, in 1 because of pruritus and in 5 patients because of non-compliance. No significant changes in the consumption of clotting factor concentrates and number of bleeding episodes before and during AZT treatment were noted. We conclude, that both hematological and non-hematological side effects of AZT in HIV 1-infected hemophilic patients are comparable to those seen in other risk groups. AZT does not increase the bleeding tendency in this patient group.

Bullous pemphigoid (BP)-type autoantibodies were found by Western blot (WB) analysis of epidermal extracts in the serum of 38% of HIV-seropositive patients compared with 21% of HIV-seronegative patients with chronic pruritus and 76% of patients with BP. They were further identified as BP autoantibodies (BPab) by immunoprecipitation and immunoelectron microscopy. Their incidence increased from 21% in HIV infection stage II to 37% and 43% in stages III and IV, respectively. Of the patients suffering from HIV-related chronic pruritic papulovesicular eruption. 75% showed circulating BPab as compared with 29% in those without skin problems (P = 0.0066) and, among them, 30% met the diagnostic criteria for BP when histology, WB, immunofluorescence and immunoelectron microscopy techniques were used. In conclusion, this study identifies an autoimmune skin reaction that may account for, or be related to, the distressing pruritic eruptions occurring in HIV-infected patients.
