Keratinocyte T6 antigen expression after PUVA therapy.
We report T6 antigen expression on keratinocytes in 11 cutaneous T lymphomas treated by PUVA therapy. This staining was absent before treatment. T6 reactivity was strictly limited to cell membrane. The nature of this expression is discussed, and it is suggested that it could be attributed to a passive diffusion from Langerhans's cells.

Cutaneous immunological studies in diagnosis of acute graft-versus-host disease.
A comparative study of the healthy skin of patients who had undergone bone marrow grafting and not developed graft-versus-host disease (GVHD) and of patients with cutaneous lesions of acute GVHD has been carried out. The aim of this study was to assess the diagnostic value of cutaneous immunopathology in the diagnosis of acute GVHD. A double-labelling immunofluorescence technique was used with a panel of monoclonal antibodies. The results showed a lack of specificity for GVHD in the distribution of Langerhans cells, but confirmed the diagnostic value of HLA-DR staining of epidermal keratinocytes. Cellular polymorphism of the T cell infiltrate in the dermis was observed (T helpers 40% and T suppressors 20%). The expression of the 55-57 Kd keratin polypeptide and of bullous pemphigoid antigen showed modification during acute GVHD while that of pemphigus antigen remained unchanged.

[Value of correlated immunofluorescence and immunoperoxidase study of monoclonal markers in 2 adult cases of histiocytosis X].
Two cases of adult histiocytosis X have been studied using monoclonal antibodies on skin sections by two techniques: indirect immunofluorescence and immunoperoxidase. This study confirm: --that histiocytosis X express two specific antigens Ia and T6, --the relations between Langerhans cell and histiocytosis X. Especially, it suggests that histiocytosis X cell would be a dedifferentiated cell with receptors OKT4 and OKT10.

[Results of a French nationwide survey of cutaneous side effects of ketoprofen gel reported between September 1996 and August 2000].
A French nation-wide pharmacovigilance survey of ketoprofen topic collated, from September 1996 to August 2000, 770 cutaneous side-effects. The frequency varies from 0.013@1000 to 0.028@1000 according to the commercial gel. Analysis concerns spontaneous notifications of French nation-wide pharmacovigilance. Sex ratio is well distributed, population is young. Treatment lasted about 12 days, the side-effects appearing after about 13 days, 25 per cent of cases are delayed to discontinuance of treatment, mainly after exposure to sunlight. Co-administered drugs are in most cases systemic or topical NSAIDs and/or fibrates and then increase the seriousness of the iatrogenic pathology. 75 per cent of cutaneous side-effects appear in summer, 50 per cent have been reported as "photosensitivity". Reactions are severe in 30 per cent of the cases. More than 80 per cent of cases present an extension beyond the site of application. The course is usually favourable and neither topical nor systemic corticosteroid treatment influence the duration of evolution. Photopatchtests testing in 23 per cent of cases show evidence of photoallergy to ketoprofen and crossed photoallergy with tiaprofenic acid, fenofibrate, oxybenzone and benzophenone. These results confirm that photoallergy is due to the common benzoylketone structure but not to their arylpropionic function. Some cases of persistent or recurrent photosensitivity must be more explored. The results lead to request a modification of marketing authorizations.

[Cutaneous side effects of ketoprofen gels: results of a study based on 337 cases].
Ketoprofen gels, since their introduction on the French market (1989), have been responsible for various cutaneous side-effects (essentially photosensitization and contact eczemas). A study conducted by the French drug surveillance system detected 337 cases. Analysis showed that the frequency of cutaneous adverse events was from 0.008/1000 to 0.023/1000 according to the commercial gel. The sex ratio was well distributed, and the population was young (30-40 years) and athletic. Treatment lasted about 7 days, and the appearance of the side-effect was sometimes quite delayed relative to discontinuance of treatment. Reactions were severe in 40 per cent of cases. The factors favourable to side-effects were essentially exposure to the sun (one-third of cases) and occlusive dressing. No particular predisposing conditions were noted, although 2.6 per cent and 8.5 per cent of cases respectively involved earlier sensitization by a topical NSAID. The side-effect lasted about 16 days. The course was usually favourable but hospitalization was required in about 10 per cent of cases. Photoallergological testing indicated photosensitization to ketoprofen. These results led the National Commission of the French drug surveillance system to request a modification in the indications for the prescription of the ketoprofen gels.
