Epidemiological profile of rosacea in dermatology outpatient clinics in Brazil: an observational report from the Brazilian study group on rosacea.

BACKGROUND: Rosacea prevalence varies worldwide and there is a lack of information in Brazil. OBJECTIVES: To describe the epidemiological profile of rosacea in subjects who consulted in dermatological outpatient clinics in Brazil. MATERIALS & METHODS: A cross-sectional study was conducted in 13 dermatological outpatient clinics across the country. Patients with rosacea diagnosis were eligible for the study according to the investigator's clinical assessment. Clinical, social and demographic data were collected. The overall and regional rosacea prevalence was calculated, and association with baseline characteristics was analysed. RESULTS: A total of 3,184 subjects were enrolled, and rosacea prevalence was 12.7%. The southern region of Brazil presented a higher prevalence, followed by the southeast. The subjects in the rosacea group were older than those without rosacea (52.5 ±14.9 vs. 47.5 ±17.5; p<0.001). Moreover, the rosacea group was associated with Fitzpatrick's phototypes I and II, Caucasian ethnicity, a family history of rosacea, and facial erythema, however, no association with gender was found. The most prevalent clinical sign and clinical subtype in rosacea patients were erythema and erythematotelangiectatic, respectively. CONCLUSION: Rosacea is highly prevalent in Brazil, mostly in the southern region, associated with phototypes I and II and a family history.

Efficacy of a topical serum containing L-ascorbic acid, neohesperidin, pycnogenol, tocopherol, and hyaluronic acid in relation to skin aging signs.

BACKGROUND: Skin aging is a process regulated by chronological aging and amplified by exposome factors including chronic UV exposure and pollution, which both induce reactive oxygen species. Topical antioxidants have the potential to counteract this process and to improve skin aging signs, including wrinkles and hyperpigmentation. OBJECTIVE: To evaluate the efficacy of a topical antioxidant serum containing 15% L-ascorbic acid, neohesperidin, Pinus pinaster bark, tocopherol, and hyaluronic acid (HA) ex vivo on air pollution-induced pigmentation and gene expression, as well as in vivo on skin aging signs in Brazilian volunteers, after 90 days of use. METHODS: Ex vivo human skin samples were repetitively exposed to Diesel Exhaust Particles (DEP) and subsequently analyzed for changes in pigmentation and gene expression. Clinical efficacy was evaluated in 40 healthy adult females with phototype II to IV and visible photoaging signs, including facial hyperpigmentation, through dermatological evaluation and instrumental analysis including Reflectance Confocal Microscopy. RESULTS: Ex vivo, the topical antioxidant serum significantly reduced DEP-induced skin pigmentation and expression of proinflammatory genes. A significant improvement of skin aging signs was observed after 90 days. Local tolerance was good. CONCLUSION: The tested serum is effective in protecting human skin ex vivo against air pollution-induced skin pigmentation/aging and reduced in vivo skin aging signs, with a good safety profile after 90 days of daily use.

Over the Counter Products for Acne Treatment and Maintenance in Latin America: A Review of Current Clinical Practice.

BACKGROUND: The prevalence and clinical presentation of acne vulgaris in Latin America are comparable to that in Europe and the United States. This review aims at insight into the role of Over the Counter (OTC) products in acne treatment and maintenance in Latin America. METHODS: A panel of dermatologists from Latin America employed an online procedure to answer questions on this topic: What is used, by whom, when, how, and why? Before the meeting, a survey was completed by dermatologists from Latin America on OTC products for acne recommended by the panel in their clinical practice. The survey information and a literature review on Latin American acne guidelines and clinical studies were used to address this topic. RESULTS: The survey responders' choices on OTC products for monotherapy comprised alpha-hydroxy acid and beta-hydroxy acid-containing serum, ceramides-containing foaming cleanser, a soap-free exfoliating cleanser, adapalene, and benzoyl peroxide-containing products. The clinicians recommended OTC cleansing products mainly for younger patients at a starter level and for women with adult acne. The use of these OTC products is similar to practice described in therapeutic acne guidelines and algorithms for Latin American countries, Spain and Portugal, Europe, and the United States. CONCLUSIONS: Advisors agreed that OTC products and skincare recommendations, in addition to the use of prescription medications, are a crucial part of successful acne therapy. Participants noted that the use of quality OTC products could improve acne symptomatology and severity.

Cardiomiopatia hipertrófica: atualizaçäo e relato de 6 casos na forma apical / Hypertrophic cardiomyopathy: update and present of 6 cases on apycal form

A entidade conhecida como Cardiomiopatia Hipertrófica continua, nos dias atuais, sendo objeto de exaustivos estudos pelos pesquisadores. Desde a descriçäo inicial da cardiopatia feita por Brock em 1957, uma ampla variedade de indagaçöes permanece em discussäo. O objetivo deste trabalho é proceder uma revisäo da Cardiomiopatia Hipertrófica e apresentar seis casos na sua forma apical, onde, ao contrário daqueles inicialmente descritos, näo säo pacientes descendentes de japoneses

Cardiomiopatia hipertrófica: atualizaçäo e relato de 5 casos na forma apical / Hypertrophic cardiomyopathy: update and presents of 5 cases on its apical form

Na análise de 56 pacientes portadores de cardiomiopatia hipertrófica, detectou-se a presença de 5 (8,9 por cento) na forma apical, näo descendentes de orientais. O envolvimento apical na cardiopatia hipertrófica foi originariamente descrito por autores japoneses, perfazendo um percentual de até 25 por cento da populaçäo de hipertróficos em algumas séries daquele país. Concordante com os relatos daquele país, observou-se um caráter evolutivamente benigno da enfermidade, näo tendo ocorrido óbito nesse grupo.
