The risk of high-grade squamous intraepithelial lesions in women with low serum levels of vitamin A.

BACKGROUND: The progression of the cervical squamous intraepithelial lesion (SIL) is associated with many cofactors, and nutritional aspects are gradually assuming an important role in understanding the physiopathogenesis. OBJECTIVE: To assess the serum levels of retinol in women from a poor region of Brazil with a histological diagnosis of cervical high-grade SIL (HSIL). METHODS: A cross-sectional study was conducted in 62 women aged 14-48 years who had a cervical biopsy and were treated at the Federal University of Ceara in Fortaleza, Brazil. Serum retinol levels were measured in peripheral blood by a spectrophotometry technique. Values were categorized as subnormal (<20 µg/dl) or normal (≥20 µg/dl). Multivariate logistic regression was used to determine the association between serum levels of retinol and HSIL for a confidence interval of 95%. RESULTS: Twenty-six out of 62 women (42%) had a negative histopathological result for SIL and 36 (58%) were diagnosed with SIL (20 low SIL and 16 high SIL). The level of retinol was more frequently low in women with HSIL, but there was no statistical significance [p = 0.409, OR: 2.26 (0.33-15.59)]. CONCLUSION: There was no association between high SIL and low levels of retinol in peripheral blood.

[Vaginal discharge in pregnant women: comparison between syndromic approach and examination of clinical nursing practice]. / Corrimentos vaginais em gestantes: comparação da abordagem sindrômica com exames da prática clínica da enfermagem.

This is a study for assessment of a quantitative approach in pregnant women (N=104), in which findings of vaginal infection were compared. The findings were obtained by two means, flowchart of vaginal discharge, and typical examinations in the clinical nursing practice. Data were collected from January to July 2011 through interviews and gynecological examinations. The flowchart showed no efficacy to identify candidiasis and trichomoniasis. Furthermore, it showed low sensitivity (0.0%; 50%) and positive predictive value (0.0%; 3.6%) for both infections, and low specificity for trichomoniasis (46%). The flowchart was shown to be satisfactory for bacterial vaginosis, with high sensitivity (100%), negative predictive value (100%), and accuracy (74%). We conclude that use of the flowchart should be reassessed, as it was not able to identify important infections in pregnant women. A continuous effort must be directed for development of effective tests in order to prevent the spread of infection and reduce the number of unnecessary treatments.

Atypical Squamous Cells: Cytopathological Findings and Correlation with HPV Genotype and Histopathology.

OBJECTIVE: We aimed to assess potential associations between atypical squamous cell (ASC) subgroups: ASC-US (undetermined significance) and ASC-H (cannot exclude high-grade squamous intraepithelial lesion), regarding cytomorphological features, high-risk (HR) human papillomavirus (HPV) testing, and histological outcomes in a sample of Brazilian women. STUDY DESIGN: Cross-sectional study which evaluated 1,346 liquid-based cytologies between January 2010 and July 2016 with ASC results. ASC-US and ASC-H were analyzed for frequency, diagnostic criteria, and cytological findings and compared with HR-HPV tests and histological outcomes. RESULTS: Enlarged nucleus was the most frequent ASC-US criterion, but alternative criteria were present in 20% of the total cases. No ASC-US criteria were associated with histological outcomes or HR-HPV positivity. Parakeratosis, corneal pearl, giant cells, and binucleation were strongly associated with ASC-US while hyperkeratosis was associated with high-grade squamous intraepithelial lesions (HSIL) or a superior outcome. HR-HPV was positive in 64.39% of ASC-US and 65.38% of ASC-H. HSIL or superior outcomes also occurred in 13.33% of ASC-US and 64.71% of ASC-H cases. CONCLUSION: Alternative criteria for ASC-US were relatively frequent. Reactive cellular changes suggestive of atypias were more abundant in ASC-US. Although ASC-H is associated with worse histological outcomes, no differences in HPV positivity were found in comparison to ASC-US.

Corrimentos vaginais em gestantes: comparacao da abordagem sindromica com exames da pratica clinica da enfermagem / Flujo vaginal en gestantes: comparacion entre el abordaje sindromico y las pruebas en la practica clinica de enfermeria / Vaginal discharge in pregnant women: comparison between syndromic approach and examination of clinical nursing practice

Estudo avaliativo de abordagem quantitativa, com amostra de 104 gestantes, com o objetivo de comparar os achados de infecções vaginais em gestantes obtidos por meio do fluxograma de corrimento vaginal com exames presentes na prática clínica da Enfermagem. Os dados foram coletados por meio de entrevista e exame ginecológico realizados de janeiro a julho de 2011. O fluxograma não se mostrou eficaz na identificação de candidíase e tricomoníase, apresentou baixa sensibilidade (0,0%; 50%) e valor preditivo positivo (0,0%; 3,6%) para as duas infecções e baixa especificidade para tricomoníase (46%). Mostrou-se satisfatório para vaginose bacteriana, com alta sensibilidade (100%), valor preditivo negativo (100%) e acurácia (74%). Conclui-se que o emprego do fluxograma precisa ser reavaliado, visto que não foi eficaz em identificar infecções importantes em gestantes. Os esforços para o desenvolvimento de testes eficazes devem ser contínuos, com intuito de prevenir a disseminação de infecções e reduzir tratamentos desnecessários.

Estudio evaluativo con enfoque cuantitativo, con una muestra de 104 gestantes, cuyo objetivo fue comparar los resultados de infecciones vaginales en las gestantes, obtenidos a partir del diagrama de flujo vaginal y las pruebas presentes en la práctica clínica de enfermería. Los datos fueron recolectados por entrevista y examen ginecológico, realizados de enero a julio del 2011. El diagrama de flujo no fue eficaz en la identificación de candidiasis y tricomoniasis, presentando baja sensibilidad (0,0%; 50%) y valor predictivo positivo (0,0%; 3,6%), para las dos infecciones y baja especificidad para tricomoniasis (46%). Para vaginosis bacteriana, se mostró satisfactoria, con alta sensibilidad (100%), valor predictivo negativo (100%) y precisión (74%). Se concluye que el uso del diagrama necesita ser revisado, ya que no fue eficaz en la identificación de infecciones importantes en las gestantes. Los esfuerzos para desarrollar pruebas efectivas deben ser continuos, con el objetivo de prevenir la propagación de infecciones y reducir tratamientos innecesarios.
