[Darier's erythema annulare centrifugum of neonatal onset with a 15 years' follow-up. Efficacy of interferon and role of cytokines]. / Erythème annulaire centrifuge de darier à ddebut néonatal avec 15 ans de suivi. Efficacité de l'interféron et rôle de cytokines.

INTRODUCTION: Darier's erythema annulare centrifugum (EAC) is a disease of unknown etiology. Some observations of EAC in infancy suggest a better prognosis for early EA. The observations presented herein gives different information regarding prognosis and pathogenesis. OBSERVATION: A child presents with typical lesions of EAC from early infancy up to the age of 15 years. Laboratory data are normal. Similar lesions were locally reproduced by intradermal injection by candidine but antifungal drugs were unsuccessful. Many antiinflammatory treatments failed to improve the disease. Because of the improvement during hyperthermic episodes, a treatment by subcutaneous interferon alpha (2 millions U 3 times a week) was given for six months with a dramatic success (with seric increase of TNF alpha and IL2) DISCUSSION: The long term duration of EAC suggests that EA of infancy may represent the early beginning of Darier's EAC. The efficacy of interferon suggests that cytokines are involved in the pathogenesis of EAC.

A study of familial lupus erythematosus-like disease and hereditary angio-oedema treated with danazol.

Immunological and genetic studies were performed in a family in which the mother and five siblings had hereditary angio-oedema (HAE). LE cells, antinuclear factors, antibodies to double-stranded DNA and positive direct Coombs' test were not found in any of the subjects. One female sibling had a lupus erythematosus-like illness with skin lesions of the face which responded to danazol treatment. Laboratory evidence of HAE was obtained in the entire kindred and all the siblings shared HLA haplotype AIB7 inherited from the deceased mother.

[Antiperinuclear factors in psoriasis. Correlation with other serological abnormalities in 90 patients]. / Anticorps anti-périnucléaires dans le psoriasis. Recherche d'une corrélation avec les autres anomalies sérologiques chez 90 malades.

Antiperinuclear factors (APF), studied in 90 patients suffering from psoriasis, were found in psoriasis without arthritis, in psoriasis with psoriatic arthritis and in psoriasis with true rheumatoid arthritis (RA): respectively 57, 36 and 43 p. 100. Patients with APF did not differ from patients without APF apart form rheumatoid factors detected by indirect immunofluorescence. They were much more frequent in psoriasis with APF. These results are compared with those of RA. They lead to look for other auto-antibodies in psoriasis.

[Accidental localized vaccinia. A report of six recent cases (author's transl)]. / La vaccine accidentelle localisée. A propos de six observations récentes.

Vaccination against smallpox should be discontinued in all countries except for individuals with a high risk of exposure (WHO, 1980). Since this vaccination is performed less and less often, one must expect complications to occur, the etiology of which may not be recognized. This course of events leads the authors to point out the difficulties in diagnosis and therapy of localized accidental vaccinia encountered in six patients hospitalized in Brest (1971-1979). Diagnosis is considered if the patient himself, or a person he came in contact with, was recently vaccinated. Diagnosis should always be established by virology. Such accidents can be avoided by a faultless vaccination technique and by giving sufficient information to the inoculated subject or to his relatives.

[Acquired ichtyosis and bronchial cancer; report on two cases (author's transl)]. / Ichtyose acquise et cancer bronchique. A propos de deux nouvelles observations.

Acquired ichtyosis appears to be a rather rare paraneoplasic syndrome, mainly observed during the course of Hodgkin's disease, but also accompanying visceral cancers. Two cases of generalised ichtyosis in patients with bronchial carcinoma are reported, emphasis being placed on the need for systematic investigations to determine this possible aetiology. Diagnostic problems are discussed, as well as hypotheses concerning the pathogenicity of these affections, which is still obscure, emphasis being placed on the secretory potential of these tumours and the role of immunological phenomena.

[Two cases of skin pigmentation in association with minocycline therapy (author's transl)]. / Deux cas de pigmentation cutanée au cours de traitements par la minocycline.

Report of two cases of skin pigmentation during minocycline therapy. Examination showed confluent blue-gray oval patches on the anterior part of the legs, occurring after ingestion of respectively 12 g and 100 g of minocycline. Microscopic examination of each case was identical and showed two lesions: increase in the amount of melanine deposition in the basal layer of the epidermis; presence of brown-black pigment at all the level of the dermis but specially near the sweet glands. This pigment was strongly positive with Perls' stain. Electron microscopic examination showed a finely granular pigment exclusively intracellular in dermis fibroblast and macrophage. This pigment seemed to contain mainly hemodiderine.
