ABSTRACT BACKGROUND: Managing cervical intraepithelial neoplasia grade 2 (CIN2) is challenging, considering the CIN2 regression rate, perinatal risks associated with excisional procedures, and insufficient well-established risk factors to predict progression. OBJECTIVES: To determine the ability of p16INK4a and Ki-67 staining in biopsies diagnosed with CIN2 to identify patients with higher-grade lesions (CIN3 or carcinoma). DESIGN AND SETTING: Cross-sectional study conducted at a referral center for treating uterine cervical lesions. METHODS: In 79 women, we analyzed the correlation of p16INK4a and Ki-67 expression in CIN2 biopsies with the presence of a higher-grade lesions, as determined via histopathology in surgical specimens from treated women or via two colposcopies and two cytological tests during follow-up for untreated women with at least a 6-month interval. The expression of these two biomarkers was verified by at least two independent pathologists and quantified using digital algorithms. RESULTS: Thirteen (16.8%) women with CIN2 biopsy exhibited higher-grade lesions on the surgical excision specimen or during follow-up. p16INK4a expression positively and negatively predicted the presence of higher-grade lesions in 17.19% and 86.67% patients, respectively. Ki-67 expression positively and negatively predicted the presence of higher-grade lesions in 40% and 88.24% patients, respectively. CONCLUSIONS: Negative p16INK4a and Ki67 immunohistochemical staining can assure absence of a higher-grade lesion in more than 85% of patients with CIN2 biopsies and can be used to prevent overtreatment of these patients. Positive IHC staining for p16INK4a and Ki-67 did not predict CIN3 in patients with CIN2 biopsies.

ABSTRACT The Medical Malacology Collection (Fiocruz-CMM) was inaugurated in 1993 and is located at the René Rachou Institute in Fiocruz (Belo Horizonte, MG, Brazil). The collection has about 16,000 limnic mollusks of medical and veterinary importance. Information about each specimen is stored in an electronic Microsoft Excel spreadsheet and is available on the Centro de Referência em Informação Ambiental (CRIA) webpage. A QR Code system was implemented for convenience: it can be printed in reduced format with flexible representation on different surfaces and has a low cost of implantation. A script in PHP language was developed to load the spreadsheet in XLS format using an open-license library, PHP-ExcelReader. A PHP script was created to read and process this spreadsheet line by line and generate individual HTML pages, which were formatted with the Bootstrap tool. Then, the PHP QR code was used to create the images of the QR codes corresponding to each specimen. The QR codes were printed and affixed to the lids of the bottles containing each specimen. Using a device with a camera and internet access, the QR code redirects to the file with the information for each mollusk. The use of QR codes at Fiocruz-CMM facilitates the organization of the collection and allows quick and easy access to information about each specimen.

Resumo OBJETIVO: caracterizar os materiais educativos impressos sobre esquistossomose produzidos no Brasil, nos níveis federal, estadual e municipal. MÉTODOS: os materiais foram caracterizados considerando-se as categorias 'formato', 'parasito e hospedeiro intermediário', 'hospedeiro definitivo' (doente) e 'doença'. RESULTADOS: dos 60 materiais avaliados, três não traziam informação sobre as atividades de risco e 41 indicavam mais de um nome popular para a doença, possibilitando maior alcance do público-alvo nas diversas áreas endêmicas; em 53 materiais, o ciclo biológico estava ausente ou incorreto; o molusco, hospedeiro intermediário, estava retratado incorretamente, com imagens estereotipadas em 39 materiais, e ausente em um; o diagnóstico foi mencionado em 36 materiais. CONCLUSÃO: os materiais educativos impressos avaliados mostraram incorreções que podem comprometer o trabalho de educação em saúde; ademais, o diagnóstico da esquistossomose foi pouco abordado.

Abstract OBJECTIVE: to characterize printed educational materials about schistosomiasis produced at federal, state and municipal levels in Brazil. METHODS: the educational materials were characterized considering the following categories: 'format', 'parasite and intermediate host', 'definitive host (ill)' and 'disease'. RESULTS: 60 materials were assessed, three had no information about risk activities and 41 indicated more than one popular name for the disease, thus allowing greater reach among the target audience in diverse endemic areas; the biological cycle was missing or incorrect in 53 materials; the intermediate host (snail) was incorrectly illustrated, with use of stereotyped images in 39 and no image in one material; diagnosis was mentioned in 36 materials. CONCLUSION: the printed educational materials assessed had incorrect content which may compromise health education efforts; little attention was paid to schistosomiasis diagnosis.

Resumen OBJETIVO: evaluar materiales educativos impresos (MEIs) sobre esquistosomiasis producidos en Brasil a nivel Federal, Estatal y Municipal. MÉTODOS: los MEIs fueron sometidos a una evaluación de contenidos teniendo en cuenta las categorías: formato, parásito y hospedero intermediario, hospedero definitivo y enfermedad. RESULTADOS: de los 60 MEIs evaluados, tres no tenían información sobre actividades de riesgo y 41 daban más de un nombre popular a la enfermedad, permitiendo un mayor alcance de público objetivo en diferentes zonas endémicas; en 53 MEIs el ciclo de vida no era mencionado o era incorrectoo; el molusco, hospedero intermediario, era retratado incorrectamente, con imágenes estereotipadas em 39 MEIs y ausente en uno; se daba poca importancia al diagnóstico, siendo mencionado en apenas 36 de ellos. CONCLUSIÓN: los MEIs mostraron inexactitudes que podrían comprometer el trabajo de educación de la salud.
