Brazilian consensus on photoprotection

Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of non-melanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection.

Penectomia em equino com carcinoma de células escamosas

The presence of increased volume in penis and prepuce of horses can be of neoplastic or non-neoplastic origin. Squamous cell carcinoma (SCC), papilloma, fibropapiloma, melanoma and sarcoidorigin. Squamous cell carcinoma (SCC), papilloma, fibropapilloma, melanoma and sarcoid are detached as neoplastic causes. The non-neoplastic causes can be parasitic as habronemiasis and pythiosis, or inflammation, resulting in the formation of exuberant granulation tissue. The penile disorders can be easily confused with each other because they have similar clinical signs. Among epithelial neoplasms affecting penis and prepuce, squamous cell carcinoma is the most common in horses. Thus, it was aimed to report a case of squamous cell carcinoma in a horse and describe the main differential diagnosis for this disease. The additional tests to obtain an accurate diagnosis and the institution of appropriate treatment are essential for the satisfactory repair of penile neoplasms in this species.
