1. Fibroblast morphology, growth rate and gene expression in facial melasma
Abstract Background: In addition to melanocytic hyperfunction, changes are observed in the upper dermis of melasma, and fibroblasts play a central role in collagen synthesis and pigmentation induction. Objective: To explore the morphology, growth rate, and gene expression profile of fibroblasts from the skin with melasma in comparison to fibroblasts from t

3. Expression of OPN3 in fibroblasts, melanocytes, and keratinocytes of skin with facial melasma in comparison with unaffected adjacent skin
Abstract Sporotrichosis is a subcutaneous mycosis that affects humans and animals, with a typically subacute or chronic evolution, caused by Sporothrix spp., a dimorphic fungus. Although the cutaneous form is the most frequent presentation, the ocular involvement has been more frequently diagnosed in endemic areas, affecting mainly children and the elderly.

4. Evaluation of ex vivo melanogenic response to UVB, UVA, and visible light in facial melasma and unaffected adjacent skin,
Abstract Background: The independent role of solar radiation in the differential melanogenesis between melasma and adjacent skin is unknown. Objectives: To assess the melanogenic responses of skin with facial melasma and of the adjacent skin to UVB, UVA, and visible light, in an ex vivo model. Methods: This was a quasi-experimental study involving 22 pati

5. The Anti-melanogenesis Activities of Some Selected Brown Macroalgae from Northern Coasts of the Persian Gulf
Abstract Melanogenesis is a biological process which led to the synthesis of melanin pigment. Abnormal melanin production results in melasma, solar lentigo, post inflammatory melanoderma, etc. In this study, we examined the potential inhibitory effects of 17 brown macroalgae from Persian Gulf on melanogenesis. The effects of various concentrations (100, 250

6. Development and validation of a multidimensional questionnaire for evaluating quality of life in melasma (HRQ-melasma)
Abstract: BACKGROUND: Melasma has a major impact on quality of life. MELASQoL is the only validated specific psychometric instrument to evaluate melasma QoL. OBJECTIVE: To develop and validate a multidimensional questionnaire for evaluating quality of life related to facial melasma. METHODS: Cross-sectional study performed in 2 institutions (public and pr

8. Tretinoin peel: a critical view
Abstract The tretinoin peel, also known as retinoic acid peel, is a superficial peeling often performed in dermatological clinics in Brazil. The first study on this was published in 2001, by Cuce et al., as a treatment option for melasma. Since then, other studies have reported its applicability with reasonable methodology, although without a consistent scie

9. Incidence of skin diseases diagnosed in a public institution: comparison between 2003 and 2014
Abstract Epidemiology of diseases is influenced by population socio-demographic circumstances. Therefore it can be modified along the time. There are no studies exploring epidemiological transition in dermatology. This study investigated the incidence of dermatoses in new patients from a Brazilian country town public service in 2003 and 2014. There was a sig

10. Psychometrican analysis and dimensional structure of the Brazilian version of melasma quality of life scale (MELASQoL-BP)
Abstract: Background: Although asymptomatic, melasma inflicts significant impact on quality of life. MELASQoL is the main instrument used to assess quality of life associated with melasma, it has been validated in several languages, but its latent dimensional structure and psychometric properties haven´t been fully explored. Objectives: To evaluate psycho
