RESUMO
BACKGROUND: Therapeutic decisions in psoriasis are influenced by disease factors (e.g., severity or location), comorbidity, and demographic and clinical features. OBJECTIVE: We aimed to assess the reliability of a mobile telephone application (MDi-Psoriasis) designed to help the dermatologist make decisions on how to treat patients with moderate to severe psoriasis. METHOD: We analyzed interobserver agreement between the advice given by an expert panel and the recommendations of the MDi-Psoriasis application in 10 complex cases of moderate to severe psoriasis. The experts were asked their opinion on which treatments were most appropriate, possible, or inappropriate. Data from the same 10 cases were entered into the MDi-Psoriasis application. Agreement was analyzed in 3 ways: paired interobserver concordance (Cohen's κ), multiple interobserver concordance (Fleiss's κ), and percent agreement between recommendations. RESULTS: The mean percent agreement between the total of 1210 observations was 51.3% (95% CI, 48.5-54.1%). Cohen's κ statistic was 0.29 and Fleiss's κ was 0.28. Mean agreement between pairs of human observers only, excluding the MDi-Psoriasis recommendations, was 50.5% (95% CI, 47.6-53.5%). Paired agreement between the recommendations of the MDi-Psoriasis tool and the majority opinion of the expert panel (Cohen's κ) was 0.44 (68.2% agreement). CONCLUSIONS: The MDi-Psoriasis tool can generate recommendations that are comparable to those of experts in psoriasis.

BACKGROUND: Current guidelines call for baseline imaging only for very high-risk (T4b) primary cutaneous melanomas. OBJECTIVES: To estimate the frequency of computed tomography (CT) at baseline staging of primary cutaneous melanoma and the diagnostic yield of CT; and to describe the types and frequencies of incidentaloma findings. MATERIAL AND METHODS: Cross-sectional study of cutaneous melanoma cases (tumor classifications Tis to T4bN0M0) attended between 2008 and 2014 in a specialized melanoma unit. Reports of CT scans performed during baseline staging were reviewed to determine the frequency of positive scan results, incidentaloma findings, unit cost for detection of metastasis, and factors associated with the decision to order CT. RESULTS: CT results were available for 310 of the 419 patients included (73.99%). The tumor classifications were as follows: Tis, 17; T1, 137; T2, 71; T3, 48; and T4, 37. The CT results were negative in 81.61%, and incidentalomas were found in 18.06%. Additional primary tumors were found in 2 patients (0.64%), and metastasis was identified in one patient (0.32%). The cost of finding the case of metastasis was 71,234.90. A T2 tumor classification (odds ratio [OR], 8.73) and age under 70 years (OR, 3.53) were associated with greater likelihood of CT being ordered. Excision of the primary tumor in the melanoma unit (OR, 0.08) was associated with less likelihood of ordering CT. CONCLUSIONS: The results for this patient series support current recommendations restricting CT at baseline to cases where there is high risk of metastasis (stagesiiC-iii).
