- Case Report: Treatment of Chromoblastomycosis with Combinations including Acitretin: A Report of Two Cases(2020) JR, Walter Belda; CRIADO, Paulo Ricardo; PASSERO, Luiz Felipe DominguesChromoblastomycosis is a cutaneous fungal infection caused by dematiaceous fungi that belong to the order Chaetothyriales and family Herpotrichiellaceae. This infection is prevalent in tropical and subtropical areas and has been designated as a neglected tropical disease according to the WHO. Chromoblastomycosis infection is difficult to treat, and there are limited therapeutic options, making urgent the characterization of new medicines or approaches to treat such infection. In the present case report, two patients with extensive chromoblastomycosis lesions were treated with the combination of itraconazole, acitretin, and imiquimod. In the fourth month of treatment, both patients showed improvement of verrucous plates, suggesting that acitretin combined with drugs already used in chromoblastomycosis therapy can decrease the time of treatment, improving patient's quality of life.

M2 subtype promotes angiogenesis, remodeling, and tissue repair (tumor proliferation). In contrast, M1 produces toxic mediators and presents antigens, destroying microorganisms and tumor cells. The microenvironment of most aggressive forms of basal cell carcinoma (BCC) shows an increase in macrophages due to M2 phenotype compared to noninvasive forms. The treatment of nodular BCC by Mohs micrographic surgery (MMS) provides high cure rates, but relapses can occur. AimsTo compare the total population of macrophages and their subpopulations M1 and M2 in cases of recurrent and nonrecurrent nodular BCC after excision by MMS. Materials & MethodsHistological sections obtained from paraffin blocks of nine cases of recurrent nodular BCC after MMS and 18 cases of nonrecurrent nodular BCC operated by MMS were immunostained for iNOS, CD204, CD163, and CD68. The expression of these markers was analyzed by image analysis. ResultsNo significant differences were found between the groups in relation to the average percentage of M1 cells, M2 cells, and total cells. Discussion and ConclusionA relationship was not seen between tumor-associated macrophages (TAM) and tumor recurrence.

- First report of cutaneous mycetoma by Paecilomyces variotii and the successful treatment with combined itraconazole and terbinafine along with resection surgeries(2021) CRIADO, Paulo Ricardo; BELDA JUNIOR, Walter; MATTA, Vania Lucia Ribeiro daMycetoma is a progressively mutilating infectious disease of the subcutaneous tissue that affects the skin and deep structures, which is poorly responsive to chemotherapy. Here, we report a skin mycetoma caused by Paecilomyces variotii, an uncommon fungus of human infections, and the therapeutic approach that resulted in a complete cure of the patient.
- Skin cancer prevention campaign in childhood: survey based on 3676 children in Brazil(2018) CRIADO, P. R.; OCAMPO-GARZA, J.; BRASIL, A. L. D.; BELDA JUNIOR, W.; CHIACCHIO, N. Di; MORAES, A. M. de; PARADA, M. B.; RABAY, F. O.; MORAES JUNIOR, O.; RIOS, R. S.; SILVA, C. S. da; FERREIRA, F. C. S.; MANDELBAUM, S. H.; VASCONCELLOS, C.Background and objectivesPrimary skin cancer prevention campaigns are essential and more effective among children, not only because of the importance of sun exposure effects during this period, but also because this age is when individuals are developing behaviours. The Brazilian Society of Dermatology - Regional State of Sao Paulo developed and conducted the programme named The Sun, Friend of Childhood', a school health education and disease prevention project for children and parents. Our objective was to evaluate the cognitive and behavioural effects of the children and parents before and after an education model-based intervention of sun protection. MethodsWe carried out a study on a school population of Social Service of Industry - Regional State of SAo Paulo, from the first to the fifth years of the regular course (6-10 years). Our educational project was planned to be based on two children's learning tools (comic magazine and a DVD cartoon). Questionnaires in relation to habits and knowledge in sun exposure were applied to the children (3776) before and (2748) after the intervention. A questionnaire was applied to 3663 parents regarding personal details and habits of their children. ResultsAccording to the McNemar's statistical test, all changes in the children in acquiring new knowledge about good practices for sun exposure were statistically significant. ConclusionsEducative sun exposure programmes in childhood are a relevant tool to modify the history of life for next generations, to concern the skin cancer and good health practices.
