Campanha de prevenção ao câncer de pele no Sul do Brasil: uma coorte retrospectiva / Skin cancer awareness campaign in Southern Brazil: A retrospective cohort study

Introdução: o prognóstico do câncer de pele está diretamente relacionado ao diagnóstico precoce. As campanhas nacionais de prevenção ao câncer de pele (CNPCPs) consistem em um importante veículo de prevenção e detecção das lesões malignas de pele. Objetivos: investigar a incidência do câncer de pele e a acurácia da dermatoscopia em pacientes atendidos na CNPCP. Métodos: um estudo de coorte retrospectiva foi realizado utilizando diretamente os dados coletados da população atendida no dia da CNPCP dos anos de 2016, 2017 e 2018 no Centro Clínico da Universidade de Caxias do Sul (CECLIN-UCS). Resultados: dos 634 pacientes incluídos no estudo, 105 foram encaminhados para realização de biópsia com estudo histopatológico da lesão. A dermatoscopia foi sugestiva de lesão maligna em 55 casos. A biópsia diagnosticou lesões malignas em 43 pacientes e lesões benignas em 32 pacientes. Sendo assim, no estudo, a sensibilidade e a especificidade do exame foram de, respectivamente, 86 e 50%. Pode-se concluir que a acurácia da dermatoscopia na identificação de lesões malignas ao longo dos três anos de campanha foi de cerca de 70%. Conclusões: a dermatoscopia nas CNPCPs apresenta um bom nível de sensibilidade e especificidade quando correlacionada aos resultados finais de exame histopatológico

Introduction: Skin cancer is the most frequent malignant neoplasm in Brazil. Its prognosis is directly related to early diagnosis and institution of adequate treatment. The Skin Cancer National Awareness Campaign (SCNAC) is an essential tool to prevent and detect malignant skin lesions. Objectives: To investigate the incidence of skin cancer and the accuracy of dermoscopy in patients assessed at the SCNAC. Methods: We conducted a retrospective cohort study using directly the data collected from the population assisted at the SCNAC day in 2016, 2017, and 2018 at Clinical Center of the Universidade de Caxias do Sul (CECLIN-UCS). Results: Of the 634 patients included, 105 were referred for biopsy with histopathological study of the lesion. Dermoscopy was suggestive of a malignant lesion in 55 cases. Biopsy diagnosed malignant lesions in 43 patients and benign lesions in 32 patients. Thus, the sensitivity and specificity of the test were 86% and 50%, respectively. The accuracy of dermoscopy in identifying malignant lesions over the three years of the campaign was around 70%. Conclusions: Dermoscopy in SCNAC has a good level of sensitivity and specificity when correlated with final histopathological results

Publication rate of abstracts presented at the annual meetings of the AANS/CNS Section on Disorders of the Spine and Peripheral Nerves.

OBJECTIVE: The objective of this study was to determine the publication rate of abstracts presented at the annual meetings of the AANS/CNS Section on Disorders of the Spine and Peripheral Nerves (Spine Summit). METHODS: The authors used a search algorithm in PubMed to determine the publication rate of abstracts presented at the Spine Summit from 2007 to 2012. The variables assessed were presentation modality, topic, meeting year, publication year, destiny journal and its 5-year impact factor (IF), country, and citation count (retrieved from the Scopus database). RESULTS: One thousand four hundred thirty-six abstracts were analyzed; 502 were oral presentations and 934 were digital poster presentations. The publication rate was 53.97% (775/1436). The mean time from presentation to publication was 1.35 ± 1.97 years (95% CI 1.21-1.49 years). The mean citation count of published articles was 40.55 ± 55.21 (95% CI 36.66-44.44). Oral presentations had a higher publication rate (71.51%, 359/502) than digital posters (44.54%, 416/934; OR 3.13, 95% CI 2.48-3.95, p < 0.001). Oral presentations had a higher number of citations (55.51 ± 69.00, 95% CI 48.35-62.67) than digital posters (27.64 ± 34.88, 95% CI 24.28-31.00, p < 0.001). The mean IF of published articles was 3.48 ± 2.91 (95% CI 3.27-3.70). JNS: Spine (191/775, 24.64%), Spine (103/775, 13.29%), and Neurosurgery (56/775, 7.23%) had the greatest number of published articles. The US represented the highest number of published articles (616/775, 79.48%). CONCLUSIONS: The publication rate of the Spine Summit is among the highest compared to other spine meetings. Many of the abstracts initially presented at the meeting are further published in high-IF journals and had a high citation count. Therefore, the Spine Summit maintains its high standards of scientific papers, which reflects the high quality of the research performed in the spine surgery field in North America.
