This technique involves collecting cells in a liquid fixative and preparing and evaluating them.Aim: This study aims to investigate cervical smears prepared using the Ezi-Prep LBC method and analyze the positivity rate for cervical cancer and assess the diagnostic accuracy of LBC in detecting cervical abnormalities among females with abnormal vaginal conditions attending a tertiary care center.Materials and methods: The present diagnostic study was performed in a tertiary care hospital over a period of 1 year (April 1, 2021-November 30, 2021). A total of 230 women, aged 21-70 years, presented at the gynecology outpatient department for either routine cervical screening or with complaints of vaginal bleeding, discharge, or pelvic pain. Cervical smears were prepared using the Ezi-Prep method and stained with ULTRA-PAP stain.Results: LBC smears are monolayer smears and are without nuclear overlapping with spread over a diameter of 16 mm. Minimum cellular overlapping and crowding were observed in LBC smears. The mean age of the participants was 35.5 ± 5.1 years. The smears were studied by using nine morphological parameters.Conclusion: The majority of the smears were inflammatory smears. A total of 16 cases and three cases were found to be bacterial vaginosis and candidiasis, respectively. In an 8-month study, HSIL was found in two cases, whereas LSIL was found in only one case.

This study aims to evaluate the effect of combining cell findings to assess urine cytology.Materials and methods: Thirty cell findings found in high-grade urothelial carcinoma (HGUC) were selected for morphological abnormalities, each with detailed definitions. All 66 HGUC and 30 benign cases were examined for morphological abnormalities. The number of cases with at least one abnormal cell finding deviating from normal cells was used. The HGUC and benign cases were compared using significance difference tests. Using the cell findings extracted by the exact tests, discriminant analysis was performed to determine the valid cell findings for HGUC diagnosis.Results: There was a difference in the detection rate of abnormal findings between HGUC and benign cases. Additionally, 20 cell findings were detected significantly more frequently in patients with HGUC. Furthermore, the discriminant analysis revealed that six cellular findings (high nucleus-to-cytoplasm ratio, hyperchromasia, eccentric nuclei, nuclear protrusion, unevenly distributed chromatin, and irregular nuclear shape) showed high accuracy in confirming the diagnosis of HGUC.Conclusions: Five- to six-cell findings were individually valid; however, the combination of cell findings is crucial for an objective and accurate diagnosis of HGUC.","PeriodicalId":50217,"journal":{"name":"Journal of Cytology","volume":"41 4","pages":"183-191"},"PeriodicalIF":1.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11676093/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142903847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have shown that the disagreement between observers, especially in the Bethesda III and IV diagnostic categories, is not insignificant at 10%-40%. In the TBSRTC 2023 version, some definitions were removed and simplified, and molecular pathology was proposed as a complement to cytopathology. The current availability of molecular tests is limited because they can be performed in a few centers and are expensive. Therefore, our study investigated intra- and inter-observer agreement according to TBSRTC 2023 using only immunohistochemically BRAFV600E antibodies.Materials and methods: The study included 173 cases with aspiration cytology evaluated between 2019 and 2022. The immunohistochemical procedure applied BRAFV600E (RM8) monoclonal antibody to cell block sections. All slides were assessed and categorized by three different observers. Data were interpreted using Cohen's kappa and Fleiss's kappa test in the Statistical Package for Social Sciences Windows 2021 program.Results: For the applied RM8 antibody, sensitivity was 64.71% and specificity was 87.27%.

They are suitable candidates for squash smear cytology (SSC) owing to their gelatinous consistency and destructive nature. SSC is an important tool for making a quick intra-operative preliminary diagnosis and taking real-time surgical and further management decisions. This study aimed to evaluate the diagnostic accuracy of SSC for chordoma cases.Materials and methods: This retrospective study conducted in a North Indian tertiary care center enrolled chordoma cases histopathologically diagnosed between 01.01.2013 and 31.07.2023, for which SSC was also performed. SSC smears and their corresponding histopathology slides (±immunohistochemistry [IHC] slides) were retrieved. Histo-cytological correlation was performed.Results: In total, 13 such cases were retrieved. The mean age was 34.4 + 5.6 years. The male-female ratio was 1:1.6. The most common location was the spheno-occipital region (10 cases), followed by sacro-coccygeal (two cases) and vertebral regions (1 case). The SSC was positive for chordoma in 10/13 cases. Thus, the calculated accuracy of SSC in chordoma diagnosis was 76.9%. A total of 3/13 (23.1%) cases where SSC was inconclusive for chordoma were difficult to diagnose cases, requiring IHC for ultimate diagnosis. Cytological features such as abundant myxoid matrix and physaliphorous cells help in correct diagnosis of chordoma on SSC.Conclusions: We found the diagnostic accuracy of SSC in chordoma diagnosis to be 76.9%. Features such as abundant myxoid matrix and physaliphorous cells are helpful in correct diagnosis on SSC. Thus, even though chordomas are rare, one should consider them among the differential diagnoses in cases presenting with appropriate clinico-radiological features and characteristic cytological findings.","PeriodicalId":50217,"journal":{"name":"Journal of Cytology","volume":"41 4","pages":"214-220"},"PeriodicalIF":1.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11676092/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142903928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All nondiagnostic cases and cases diagnosed as RCC were excluded from the study, so 57 cases of renal tumors were reviewed along with the cell blocks and ancillary studies.Results: Out of the 57 cases, 35 cases were primary renal neoplasms, which included renal oncocytoma (3.5%), angiomyolipoma (3.5%), rhabdoid tumor (1.8%), Wilms tumor (28.0%), Ewing sarcoma (3.5%), urothelial carcinoma (8.8%), and small round cell tumor unclassified (12.3%).

This study was done to evaluate the micronucleated cell count, metanuclear abnormalities, and genotoxic factor in exfoliated buccal mucosal cell among the COVID-19 suspected patients. This cross-sectional study was conducted at AIIMS, Mangalagiri, between August and October 2022. One hundred COVID-19 suspected patients were recruited for this study after obtaining informed and written consent; buccal smear was obtained and stained for papanicolaou test (PAP). The PAP-stained slides were analyzed for micronuclei (MN), pyknotic, karyolytic, and karyorrhexic cell count, respectively. Based on their reverse transcription-polymerase chain reaction (RT-PCR) report, the patients were grouped into COVID-19 positive and negative groups. The genotoxicity factor was calculated using the micronucleated cell count from both the groups using mean and standard deviation. The MN, micronucleated cell, pyknotic, karyolitic, and karyorrhexic cell count in COVID-19 positive patients were 24.12, 15.24, 3.08, 2.88 and 4.40, respectively, than COVID-19 negative patients 5.69, 8.17, 1.08, 1.00 and 2.43, respectively. The genotoxicity factor for SARS-CoV-2 was 2.68 which is a positive genotoxic effect on buccal mucosal cells. SARS-CoV-2 increases the expression of micronucleated cells, pyknotic cells, karyolytic cells, and karyorhexic cells and concludes SARS-CoV-2 is having cytogenotoxic effect on the buccal mucosal cells.
