Background and purpose: The gold standards for diagnosis of thyroid nodules are cytology (FNA) and pathology. However, the role of ultrasonography is rising in detection and characterization of malignant and benign thyroid nodules. This study compared these two diagnostic methods to establish a complementary role for ultrasonography. Materials and methods: This cross-sectional study was perfor...
PURPOSE The role of peritoneal washing cytology in determining further treatment strategies after surgery for gastric cancer remains unclear. One reason for this is the fact that optimal procedures to increase the accuracy of predicting peritoneal metastasis have not been established. The aim of this study was to evaluate the efficacy of cytology using samples harvested from two different abdom...
PURPOSE To evaluate the prognostic impact of peritoneal washing cytology in patients with endometrial and ovarian cancers. MATERIALS AND METHODS We retrospectively identified 86 individuals with ovarian carcinomas, ovarian borderline tumors and endometrial adenocarcinomas. The patients had been treated at Shahid Sadoughi Hospital and Ramazanzadeh Radiotherapy Center, Yazd, Iran between 2004 a...
Purpose To assess the sensitivity of cervical cytology to cancer by pooling individual patient cytology results from cancers diagnosed in studies that assessed cervical screening in low- and middle-income countries. Methods Two authors reviewed studies identified through PubMed and Embase databases. We included studies that reported cervical cytology in which at least one woman was diagnosed ...
این تحقیق درصدد است قابلیت حالت دمایی یک روز در پیش بینی حالت بارشی روز بعد را بر اساس روش احتمال شرطی مورد بررسی قرار دهد. برای دستیابی به این هدف دادههای شبکهای با تفکیک زمانی روزانه، از 01/01/1340 تا 11/10/1383 و با تفکیک مکانی (یاخته های) 15 15 کیلومتر، مورد استفاده قرار گرفت. براساس توزیع احتمال مربوط به دمای هر یاخته و هر روز، صدک های 25 و 75 توزیع فراوانی دمای روزانۀ هر یاخته ب...
Background and purpose: Practical use of cytology in diagnosis of skin cancers is limited due to lack of information regarding its reliability and accuracy. This study assessed the diagnostic value of scraping cytology in superficial skin cancers. Materials and methods: We compared papanicolaou stained glass slides of scraped samples of 60 suspicious skin lesions to H and E stained histologic ...
Performing frozen section is a common intraoperative consult with the goal of determining the lesion as benign or malignant. Since frozen section needs specific technical requirements and costs a lot therefore, in some studies cytology is used as an alternative method. Most of these studies have been done on specific organs and a few of them on all organs of the body. Therefore, we ...
Numerous tools and techniques such as vital stain, autofluorescence, exfoliative cytology, histomorphometry, etc. were explored in the detection of dysplasia, but have variable sensitivity specificity. The present study evaluated effect toluidine blue increasing accuracy histomorphometry analysis dysplasia OPMDs on cytology. An experimental, observational, cross-sectional research was performed...
BACKGROUND Northern Thailand is a region with a high cervical cancer incidence. Combined high-risk HPV (hrHPV) DNA testing and cytology (co-testing) has increasingly gained acceptance for cervical cancer screening. However, to our knowledge, data from a population-based screening using co-testing have not been available in this region. This study therefore aimed to evaluate the performance of c...
OBJECTIVE The clinical management of patients with thyroid nodules that are biopsied by fine-needle aspiration cytology and yield indeterminate results remains unsettled. The BRAF V600E mutation has dubious diagnostic value due to its low sensitivity. Novel strategies are urgently needed to distinguish thyroid malignancies from thyroid nodules. DESIGN This prospective study included 504 thyro...
