Reflectance confocal microscopy - Consensus terminology glossary in Brazilian Portuguese for normal skin, melanocytic and non-melanocytic lesions

Abstract Background: Currently, there is no uniform and official terminology in Portuguese for reflectance confocal microscopy analysis, despite the increasing number of Brazilian dermatologists using this new tool. Objective: To present the terminology in Brazilian Portuguese for the description of reflectance confocal microscopy and establish the first Brazilian consensus on terms related to normal skin and cutaneous tumors. Methods: 10 Brazilian specialists from different institutions and states of Brazil were selected to evaluate the best corresponding terms in Portuguese for normal skin, melanocytic and non-melanocytic tumors. The terms used were translated from international consensuses in the English language. The modified Delphi method was used to create the consensus in 3 steps. Results: The terms considered the most appropriate in the Portuguese language to describe the findings of normal skin, melanocytic and non-melanocytic lesions in the reflectance confocal microscopy analysis were presented. Study limitations: The limitations of the present study include the number of participants and limited regional representation (only two of the five Brazilian regions were represented). Conclusion: This Brazilian consensus represents an opportunity for dermatologists and physicians specializing in cutaneous oncology to become familiar with reflectance confocal microscopy, propagating the technique in clinical and research environments to stimulate national and international publications on this subject.

Management of dermatologic adverse events from cancer therapies: recommendations of an expert panel

Abstract With the development of new cancer therapies, systemic toxicity profile and effects on survival achieved an important improvement. However, a constellation of toxicities has emerged, even more remarkably, cutaneous adverse events. This report, developed by a board of Brazilian experts in oncodermatology, aims to establish a guideline for the dermatological care of oncologic patients. When possible, evidence-based recommendations were made, but in many cases, when strong evidence was not available, a consensus was reached, based on some data supporting therapies combined with personal experiences.

Avaliação crítica do uso da reação em cadeia da polimerase e exames complementares no diagnóstico da tuberculose cutânea e micobacteriose atípica / The role of polymerase chain reaction and panel exams in the diagnosis of cutaneous tuberculosis and atypical mycobacteria skin infection compared to clinical evaluation

Realizou-se estudo comparando o uso da reação em cadeia da polimerase à evolução clínica e painel de exames tradicionais para diagnóstico em pacientes com suspeita clínica de tuberculose cutânea e micobacteriose atípica. Observou-se sensibilidade da reação em cadeia da polimerase de 88 por cento, especificidade de 83 por cento, valor preditivo positivo de 82 por cento, valor preditivo negativo de 88 por cento e acurácia de 85 por cento com concordância pelo teste de McNemar (p= 0,655). Os exames do painel de maior acurácia / A study was performed comparing the polymerase chain reaction and the traditional panel of exams for the diagnosis in patients with a clinical suspicion of cutaneous tuberculosis and atypical mycobacteria infection to the clinical evaluation. It was observed that the sensitivity of the PCR was 88 per cent, the specificity was 83 per cent, the positive predictive value was 82 per cent, the negative predictive value was 88 per cent and the accuracy was 85 per cent in agreement with the McNemar test (p=0.655). The panel exams of second highest accuracy...
