Anais brasileiros de dermatologia最新文献

The month of January 1925 marks the birth of the Annaes Brasileiros de Dermatologia e Syphilografia and currently, 100 years later, with great merit, we celebrate its evolution into Anais Brasileiros de Dermatologia (ABD). Indeed, those few brilliant pioneers never dreamed of the strength of the Brazilian Society of Dermatology nowadays. However, perhaps they envisioned a relevant role for ABD, with a natural space for dermatoses of infectious etiology, always prevalent in tropical and subtropical regions. And thus, it was established for decades. Currently, Brazilian Dermatology and ABD are plural and open to the different facets of Dermatology. However, both the specialty, Dermatology, and its official body, ABD, value and pay homage to history, and cannot forget or stray from it. Numerous challenges have been faced over the past 100 years. Many other challenges still remain, but it is up to us, as a gift to the 100^th anniversary of the Anais Brasileiros de Dermatologia, to learn about them and reflect on them. The following text provides a summary of the history of ABD over the years. We invite national and international readers to celebrate with us.

Exosomes are extracellular nanovesicles secreted by several cells in the human and animal body. Consisting of a lipid membrane and encapsulated proteins, they contain biologically active substances such as proteins, DNA, RNA, transcription factors, and metabolites. Discovered in the 1980s, exosomes play an important role in cell-to-cell communication and immune function. They vary in size, content, and function depending on the cell of origin. Exosomes have attracted interest in the field of Dermatology due to their potential applications in the treatment of scars, skin rejuvenation, hair regeneration, and other dermatological conditions. However, further clinical studies are needed to prove their efficacy and safety. Regulatory issues also need to be considered, as the use of exosomes in cosmetics and medical treatments is not yet fully approved in some countries. Moreover, it is important to understand the risks and side effects associated with the use of exosomes before their clinical use. Although promising, more research is needed to explore the full potential of exosomes in Medicine and Dermatology.

Background: Skin cancer is the most common neoplasm among Brazilians, accounting for 31.3% of all cancer cases in the country.

Objectives: To analyze the longitudinal morbimortality of skin cancer and compare it with the latitude and the prevalence of white skin color in each federative unit of the country.

Methods: An ecological observational study was carried out using data from the Hospital Information System (SIH) and the Mortality Information System (SIM).

Results: In Brazil, morbidity rates (per 100,000 inhabitants) increased from 14.88 to 27.69 (p < 0.05) when comparing the years 2012 and 2022, whereas the mortality rates (per 100,000 inhabitants) increased from 0.35 to 0.54 (p < 0.05) during the same period. Furthermore, most states showed an increase in morbimortality rates. Concerning race/ethnicity, individuals with white skin had the highest morbimortality rates. Regarding the age groups, individuals over 50 years old had the highest morbidity rates, while patients over 80 years old had the highest mortality rates, at 23.29%. Finally, the latitude showed a negative correlation, meaning that lower latitudes presented higher rates of morbidity and mortality from skin cancer.

Study limitations: Self-reporting of skin color by participants, which may not fully correspond to phototypes. Data was analyzed exclusively from hospitalizations through the Unified Health System (SUS) and severe cases of the disease, as this study focused on hospitalizations and mortality, considering that the main treatment for skin cancer is carried out on an outpatient basis.

Conclusions: The majority of Brazilian states showed rising morbimortality rates during the period, with the white-skinned population being the most affected. Additionally, a negative correlation with latitude was observed.
