Objective: To evaluate the quality indicators of cervical cytopathology tests carried out by the Brazilian Unified Health System [Sistema Único de Saúde (SUS)]. Method: Cross-sectional study based on the results of cervical cytopathology tests conducted in the municipality of Cascavel, Paraná, Brazil, from January 2012 to December 2018. The study included 141,191 tests and the following variables were analyzed: sample suitability, cervical cytopathology tests result, and internal quality monitoring indicators recommended by the Brazilian Ministry of Health. Results: The percentage of unsatisfactory tests did not exceed 0.97%. The representation of the squamocolumnar junction ranged from 63% to 67.4%. The percentage of altered exams among the satisfactory samples ranged from 0.46% to 6.44%. The positivity index ranged from 0.46% to 6.44%, while the high-grade squamous intraepithelial lesion/satisfactory indicator ranged from 0.21% to 1.06%, atypical squamous cells of undetermined significance/altered ranged from 22.47% to 49.93%, atypical squamous cells of undetermined significance/satisfactory ranged from 0.1% to 2.57%: and atypical squamous cells of undetermined significance/squamous intraepithelial lesions ranged from 0.31 to 1.02. Conclusion: In 2012 and 2013, the high-grade squamous intraepithelial lesion/satisfactory and the positivity index indicators were below the recommended parameters, and in the remaining years, these indicators were within the parameters recommended. Consequently, a greater number of truly cancer precursor lesions were identified, demonstrating the importance of internal quality control in the prevention of cervical cancer.","PeriodicalId":35397,"journal":{"name":"Jornal Brasileiro de Patologia e Medicina Laboratorial","volume":"56 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71116875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chromogranin A ( CHGA ) has been used as maker in cardiovascular disease. Therefore, evaluating the polymorphism and verifying its association with this pathology is very important to better understand this disease. Objective: The aim of this study was to identify the association between coding region polymorphism in -264 position of the CHGA gene ( Glu264Asp ) and hemorrhagic stroke (HS)/aneurysm in the Federal District, Brazil. Methods: This is a population-based case-control, involving 45 cases with HS and/or aneurysm. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method is used for genotyping these samples. A significance level of 5% was adopted. Results: The absence of the CC genotype the Glu264Asp CHGA polymorphism in the study participants and the significant presence of the GC heterozygote genotype were observed in this study. However, the distribution of genotypes did not differ statistically in the groups. Conclusion: The Glu264Asp CHGA polymorphism does not seem to contribute to the genesis of the CHGA protein expression in this patients group, but to understand whether or not there is a possible association of the pathology in question and whether the mutation will contribute in the gene therapy and thus to improve patients’ quality of life.","PeriodicalId":35397,"journal":{"name":"Jornal Brasileiro de Patologia e Medicina Laboratorial","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71116071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We evaluated a series of 232 cases of pure DCIS and DCIS associated with ICNST from a total of 399 breast carcinomas from a population consisting by women diagnosed with breast cancer and submitted to breast surgery from 2011 to 2015. Results: DCIS presented a mixed architectural pattern in most cases (56%); the solid subtype was the most common morphology (30%). High-grade DCIS was identified in 84/221 cases (38%), and comedonecrosis was present in 106/221 cases (48%). High-grade was more common in the solid subtype (61/155 cases, 39%, p < 0.001). Tumor size was greater in the presence of comedonecrosis than in the absence (mean 27 vs 20 mm, p = 0.009). Estrogen receptor (ER) was positive in 81% of cases with a cribriform pattern (p = 0.013). Greater locoregional recurrence was found in the comedonecrosis (15%) and micropapillary (19%) subtypes in DCIS associated with ICNST. Conclusion: We observed a greater relationship of ER with the low nuclear grade, while Ki-67 was related to the high-grade. DCIS presented a higher nuclear grade compared to ICNST. The less common pure pattern was the micropapillary, and the most common, the solid. Comedonecrosis was more frequent in the solid pattern. Our results showed that high-grade was more common in the solid and comedo subtype, and low-grade was more frequent in the cribriform.","PeriodicalId":35397,"journal":{"name":"Jornal Brasileiro de Patologia e Medicina Laboratorial","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71116378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
