Bullous pemphigoid in Liguria: a 2-year survey.

BACKGROUND: The epidemiology of bullous pemphigoid (BP) is not clear because of the heterogeneity of the disease, and its possible association with internal malignancies has been under debate for many years. We report the findings of a 2-year study on incident BP cases in the Liguria region of Italy. SUBJECTS AND METHODS: Thirty-two patients with BP were collected over the 2-year period. Diagnosis was made based on clinical findings and confirmed by histology, direct immunofluorescence (DIF) and indirect immunofluorescence (IIF) with salt-split skin and monkey oesophagus, and immunoblotting (IB). All patients were thoroughly investigated for possible malignancies and all were followed up for 6 months to monitor the response to treatment. RESULTS: DIF showed linear deposits at the dermoepidermal junction in all but one patient. IIF gave positive findings for 15 sera tested with monkey oesophagus and 20 tested with salt-split skin. IB gave positive findings in 19 cases. There was a malignancy in six cases, but no clinical or immunological features that could be considered to predict this occurrence. CONCLUSIONS: The findings of this study are in accordance with most of the data found in the literature, including the fact that IgG serum levels did not predict the course of the disease. Contrary to previous indications, IgE levels were not indicative of disease course either. Mucosal lesions, erythema multiform-like lesions, negative IIF findings and antibodies to AgPB2 were not a prediction for the development of malignancy.

Papular-purpuric gloves and socks syndrome in HIV-positive patients.

Three HIV-positive women showed clinical signs of papular-purpuric gloves and socks syndrome and serologic evidence of acute Parvovirus B19 infection. The course of the disease was complicated by anemia and persistent skin lesions, probably related to inadequate immune response. Because anemia in AIDS patients may be due to many causes, the history of recent Parvovirus B19 infection is helpful in suggesting the etiologic diagnosis.

[Lichen planus and thymoma. A case].

INTRODUCTION: Lichen planus is a chronic inflammatory disease of the skin, rarely associated with a thymoma. CASE REPORT: A 72-year-old woman with erosive buccal lichen, hypertrophic lichen planus of the lower limbs, severe myasthenia and acquired hypogammaglobulinaemia associated with thymoma. CD8 lymphocyte count was increased. In the months following surgical ablation of the thymoma, the clinical examination and laboratory findings progressively returned to normal. Two years later, the patient was in good health. DISCUSSION: To our knowledge, this is the first report of favourable outcome after surgical treatment despite the aggressive symptomatology. The particular outcome allow confirmation that the thymoma plays a causal role in this syndrome and emphasizes the effects a thymoma can have on the immune system.

[The parenteral administration of essential amino acids in patients on periodic hemodialysis treatment. A pilot study].

In an attempt to improve the nutritional status of seven hemodialysed patients, 500 ml of a 5.5% nephrological essential amino acid solution (EAA) were administered during each dialysis session for 2 months. At the end of this treatment, a significant increase in albuminemia was found (p < 0.05). These results are an encouragement to continue this therapy, especially if it is kept in mind that the half-life of albumin is much shorter than the period of EAA administration.

Cutaneous cryptococcosis resembling molluscum contagiosum in a homosexual man with AIDS. Report of a case and review of the literature.

A 43-year-old homosexual man with the Acquired Immunodeficiency Syndrome (AIDS) developed cutaneous molluscum contagiosum-like lesions on face, ears, neck, hands and feet. He was admitted to our unit with fever, malaise and headache. Cytologic examination of skin brushing revealed numerous encapsulated budding yeasts, identified as Cryptococcus neoformans. Such a finding calls for a cytologic examination of skin lesions in patient with AIDS who present with fever and headache, in order to rule out a potentially life-threatening fungal infection.

[Mibelli's porokeratosis after bone marrow transplantation].

A 24-year old male patient developed, on both legs, lesions typical of Mibelli's porokeratosis 22 months after bone marrow transplantation, under treatment with cyclosporin A. He denied any family history. Mibelli's porokeratosis seldom develops after an immunosuppressive treatment, and to our knowledge it has exceptionally been described after bone marrow transplantation. A possible complication of Mibelli's porokeratosis is the development of Bowen's disease, basal or squamous cell carcinomas. Immunosuppressive treatment might facilitate the degeneration. For this reason, these subjects should be periodically and carefully examined.

Anti-SL-Ki antibody in a patient with fatal connective tissue overlap disease.

A patient with photosensitivity is described who presented with an overlap syndrome combining features of systemic lupus erythematosus with a mild polymyositis and scleroderma and with symptoms of the sicca syndrome. In addition, he was anti-SSA/Ro positive and had a constellation of antibodies directed to ENA including the anti-SL-Ki antibody. The condition was fatal and he died from heart failure and respiratory insufficiency.

Generalized eruptive histiocytoma in children.

Generalized eruptive histiocytoma is a papular, non-X, nonlipidic, self-healing histiocytosis affecting mainly adults. This article describes the clinical, histologic, ultrastructural, and immunologic findings in four children, aged 10 months to 4 years, who were suffering from this disease. Generalized eruptive histiocytoma of children differs from generalized eruptive histiocytoma of adults only in that the lesions are not symmetrically distributed, they do not affect the mucous membranes, and they may become xanthomatous.
