Cutaneous malignant melanoma (CMM) is a skin neoplasm with increasing incidence in the recent decades, and Santa Catarina is the state with the highest incidence in the entire country. Objective: To evaluate the location, size and depth of CMM lesions in a pathology reference laboratory in southern Santa Catarina between 2007 and 2017. Methodology: A retrospective cross-sectional documentary study was carried out, consisting of the anatomopathological reports of patients whose skin biopsies were sent to the laboratory studied in the period between 2007 and 2017. Patients whose report confirmed the diagnosis of cutaneous malignant melanoma in the period between 2007 and 2017 were included. Results: We analyzed 232 cases of CCM. The highest prevalence occurred in the 50 to 69 age group. There was a linear increase in the number of occurrences in the period studied. A statistically significant association was found between the Breslow index, the presence of ulceration and the number of tumor mitoses (p<0.001). Conclusion: The data found showed a significant association between the Breslow index, the presence of ulceration and the number of tumor mitoses. [ABSTRACT FROM AUTHOR]

Historically, the conflict of interests between employers and workers obliged the State to assume the role of regulating this relationship, instituting laws and overseeing the application of health and safety standards at work. The Accident Prevention Factor (FAP) is one of these guidelines. This article aims to analyze the correlations between the FAP and the risk rate for occupational accidents in Brazil in the period between 2006 and 2016. Ecological study, which analyzed the occupational accidents, registered in the Brazilian Social Security database in the period between 2006 and 2016. The analysis included the calculation of accident risk rates according to the Brazilian regions, divisions of the CNAE, reason/situation, ICD-10 chapters, sex and age. The comparison between results from the two periods was performed using the average risk rates from the two periods using Student t test, Spearman correlation and beta value. Basically, all rate series analyzed had a strong downward trend in the FAP period, contrary to what occurred in the immediately previous period. [ABSTRACT FROM AUTHOR]
