Decision-making factors for the long-term topical treatment of mild-to-moderate plaque psoriasis: TEPPSO, a case-vignette study on clinical practice.

OBJECTIVES: Topical maintenance therapy strategy with regard to patients with mild-to-moderate plaque psoriasis (PP) continues to be heterogeneous and insufficiently investigated in real-life clinical practice. The objective of this study was to describe the initiation of long-term maintenance treatment and to identify clinical parameters influencing the therapeutic decision. METHODS: TEPPSO was a French and Belgian multicentre cross-sectional study based on completion of questionnaires and assessment of credible clinical scenarios of mild-to-moderate PP by physicians using the validated case-vignette method. RESULTS: Maintenance therapy was recommended by dermatologists (Ds) and by general practitioners (GPs) in 79.1% and 76.8% of cases, respectively. GPs recommended the use of a fixed-dose combination of corticosteroid and vitamin D analogues in only 14.8% of cases, whereas this therapy was recommended by French and Belgian Ds in 54.8% and 39.8% of cases, respectively. In a multivariate analysis, significant determinants of the therapeutic decision were skin lesions impacting quality of life (OR 1.9 [95% CI: 1.1; 3.2] P=0.01) for Ds, and patient corticophobia (OR 1.7 [95% CI: 1.1; 2.7] P=0.03) or the presence of skin pruritus (OR 1.8 [95% CI: 1.2; 1.8] P=0.004) for GPs, respectively. CONCLUSIONS: Maintenance treatment with topical agents in patients with mild-to-moderate PP was considered in more than two thirds of cases. Heterogeneity in the choice of topical agents was evidenced particularly between Ds and GPs. Our study is the first to identify significant clinical determinants affecting the therapeutic decision. Updated and validated clinical practice guidelines are needed to ensure uniform therapeutic choices.

[Cutaneous plasmacytoma: review of the literature apropos of a case]. / Plasmocytomes cutanés: revue de la littérature à propos d'une observation.

Extramedullary plasmocytomas are ubiquitous plasmocytic tumours which are principally located in bones and mucosae but rarely found on the skin. Clinically, they present as purplish-blue cutaneous nodules or, less frequently, as papular or urticarial eruptions. The diagnosis rests on histology and immunostaining. Cutaneous plasmocytomas are usually divided into two types: (1) primary plamocytomas which occur in the absence of myeloma, present as solitary or multiple skin tumours, accompanied or not by monoclonal gammopathy, and have an imperfectly known course and prognosis; (2) secondary plasmocytomas--a case of which is reported here--which appear in the course of a large tumoral mass myeloma and have a very poor prognosis.

Distal phalangeal metastasis of a chondrosarcoma presenting initially as bilateral onycholysis.

Onycholysis is the detachment of a nail plate from its distolateral attachments. There are numerous aetiologies: congenital, traumatic, microbial, toxic, dermatological, systemic and benign or malignant tumours. We report a case with onycholysis of the ring-fingers of both hands whose symmetrical and bilateral characteristics temporarily confused the diagnosis.

Dermatitis herpetiformis associated with ulcerative colitis.

Over the past 20-years, it has been shown that the majority of patients with dermatitis herpetiformis (D.H.) suffer from coeliac disease of varying intensity. Dermatitis herpetiformis may also be associated with other autoimmune diseases but only exceptionally with chronic ulcerative colitis (U.C.).
