1. Mycosis fungoides and Sézary syndrome: focus on the current treatment scenario
Abstract Cutaneous T-cell lymphomas are a heterogeneous group of lymphoproliferative disorders, characterized by infiltration of the skin by mature malignant T cells. Mycosis fungoides is the most common form of cutaneous T-cell lymphoma, accounting for more than 60% of cases. Mycosis fungoides in the early-stage is generally an indolent disease, progressing

4. Programa de controle da qualidade dosimétrico, validado com auxílio de filme radiocrômico, aplicado à radioterapia estereotáxica / Dosimetric quality assurance with the help of the radiochromic film, applied to stereotactic radiotherapy.
Radiation therapy of brain lesions near critical structures requires a highly accurate location and dose. The accuracy in dose delivery should be accompanied by an accurate quality control in devices involving the practice. The commissioning of the planning system is to ascertain and confirm the calculations performed by the system, but even with all quality

8. Desenvolvimento e caracterização de um dosímetro de cintilação para controle de qualidade em radioterapia / Development and characteriation of a scintillation dosimeter for quality control in radiotherapy
O tratamento radioterápico é um procedimento capaz de matar células tumorais, expondo elas a doses pré-calculadas de radiação ionizante. A precisão na entrega da dose é fundamental para se obter um tratamento seguro e eficaz. Com o intuito de minimizar as incertezas referentes ao tratamento, é de extrema importância a implementação de procediment

9. Efeito da clorexidina e flúor na resistência coesiva da estrutura dental irradiada e não irradiada
Radiation therapy significantly reduces the resistance of the tooth structure and the damage is potentially higher in the organic matrix. The use of products that promote the stabilization of collagen and / or agents to intensify the cross-links may provide less damage to the resistance of teeth irradiated. This study aimed analyze the effect of the use of c
