[French adaptation of a new score for global assessment of psoriasis severity: The Simplified Psoriasis Index (SPI)]. / Adaptation française d'un nouveau score destiné à l'évaluation globale de la sévérité du psoriasis : l'Indice Simplifié du Psoriasis (Simplified Psoriasis Index, SPI).

OBJECTIVE: Although several scores exist to assess psoriasis severity, most have marked limitations that rule out their use in routine clinical practice. A new score, the Simplified Psoriasis Index (SPI), has recently been developed and validated in adults in Britain for such use. It has separate components for current severity (SPI-s), psychosocial impact (SPI-p) and past history and interventions (SPI-p), and it is suitable for either professional assessment or patient self-assessment. The aim of this work was to produce a validated translation of SPI into French (as spoken in France). METHODS: The index was translated and validated using a strict methodology comprising respectively five and eight phases for the professional (proSPI) and self-administered instruments (saSPI). Translation of the saSPI instrument also involved a cognitive debriefing with five psoriasis patients. RESULTS: Linguistic discrepancies and subtle differences of meaning arising during the process were closely examined. The developer of the instrument ensured conceptual accuracy. A panel of health experts guaranteed that medical terms were correctly translated. Five patients with plaque psoriasis (two female and three male of median age 45 years [range: 31-78]) tested the SPI-p version during cognitive interviews and found the questionnaire clear and easy to understand. CONCLUSION: Validated French translations of both SPI instruments are now available for use in routine clinical practice. Further investigations are currently underway to validate the psychometric properties of the instrument.

Topical vitamin D analogues alone or in association with topical steroids for psoriasis: a systematic review.

OBJECTIVE: The objective of this systematic review was to prepare for evidence-based recommendations on the use of vitamin D analogues, and their combination with topical steroids in psoriasis. METHODS: Literature systematic review performed in May 2011. The Cochrane, PubMed and Embase databases were systematically searched with different combinations: including Psoriasis AND calcipotriol expanded to all vitamin D analogues. To assess efficacy across studies, we used two predefined criteria to account for the numerous endpoints found in the literature, 'Treatment success' corresponding to 90% improvement in severity and 'Satisfactory response' corresponding to 75% improvement. We conducted a meta-analysis comparing the efficacy of vitamin D analogues plus topical steroids (VDS) vs. vitamin D analogues alone (VD). To determine the relative cost-efficacy of the topical drugs available on the market, cost/efficacy ratios were calculated for each product according to the approved therapeutic regimen. RESULTS: 51 articles were selected. The application duration varied between three to 52 weeks across studies. VD as monotherapy had a satisfactory response rate between 22% to 96% and a treatment success rate ranging from 4% to 40%. VDS had a satisfactory response rate between 35% to 86% and a treatment success rate ranging from 27% to 53%. A meta-analysis found a probability of success twice higher with VDS than with VD in adult plaque psoriasis. The cost/efficacy ratio was evaluated as 1.2-1.8 times higher for VDS than for VD. CONCLUSION: VDS is twice more effective than VD and displays a better cost per success. Additional studies are needed to clarify maintenance treatment, impact on quality of life, treatment of non-plaque psoriasis. It will be important to harmonize outcome measures in future studies with topical agents in psoriasis to better appraise their efficacy.

Assessment of risk of psoriatic arthritis in patients with plaque psoriasis: a systematic review of the literature.

OBJECTIVE: The aim of this study was to determine the prevalence of psoriatic arthritis (PsA) in the patients with plaque psoriasis and to give recommendation for the diagnosis of PsA for dermatologists. METHODS: A systematic search was performed in Pubmed, Cochrane and Embase databases. The key-words used from the Medical Searching Heading (MeSH) were: 'Psoriasis', 'Arthritis, Psoriatic', 'Uveitis' and 'Dactylitis'. We selected cross-sectional epidemiological studies written in English or French between January 1980 and October 2009. RESULTS: The initial literature search identified 2171 references. Based on abstract reading and exclusion of studies not written in English or French, and without control group, the final selection included 20 epidemiological studies. With the eight studies using rheumatologically validated criteria, the prevalence of PsA among psoriasis patient spanned a wide range from 7% to 26%. CONCLUSION: Psoriasis arthritis may affect up to 24% of psoriasis patients. Dermatologist should be aware of main clinical sign of PsA to promote earlier recognition and treatment of PsA.

[Incidence and management of condylomata acuminata by French general physicians]. / Incidence et prise en charge des condylomes acuminés externes en médecine générale.

OBJECTIVES: Condylomata acuminata (or genital warts) are sexually transmitted diseases caused by human papillomavirus. Until now, there has been no available epidemiologic data about this disease in France. We conducted a prospective study among French general practitioners (GPs) to estimate the incidence of consultations for external condylomata acuminata in general practice. We also assessed the management of patients with external condylomata acuminata by French GP's. DESIGN: A panel of French general practitioners, members of the Sentinel network, had to fill-in prospectively a questionnaire for each patient with condylomata acuminata diagnosed between July and November 2000. RESULTS: The annual number of consultations for external condylomata acuminata with French GP's was estimated at 23,000 (CI (95 p. 100) 21,000-25,000) including 15,000 new cases (CI (95 p. 100) 13,000-17,000). Taking into account the estimations we made at the same time in office-based private dermatologists, we estimated the annual incidence of external condylomata acuminata in France at 107/100 000 inhabitants. The management of patients with external condylomata acuminata by French GP's was in accordance with the European guidelines in 54 to 78 p. 100 of cases. French GP's mostly prescribed chemical treatment. DISCUSSION: A proportion of cases of condylomata acuminata may have not been diagnosed. Similarly, some lesions may have been wrongly diagnosed as condylomata acuminata, but these proportions of false positive and false negative remain unknown. The incidence of external condylomata acuminata in France is similar to those estimated in others developed countries.
