Trichomonas vaginalis (T. vaginalis), which causes urogenital system infections in humans, develops symptomatically and asymptomatically. T. vaginalis in females is diagnosed using direct microscopy, Giemsa staining, and cultivation methods for examination of samples derived from the vaginal posterior fornix. Serologic methods can also be employed. In cytological diagnosis, the ectocervical sme...
OBJECTIVE A modified liquid-based techniques known as the "LiquiPrep (LP) system" requires neither expensive equipment nor complicated specimen preparation. The aim of this study was to assess the applicability of the LP for use in a developing country. METHODS Cervical cytology specimens were collected from 777 women, using the Cervex-Brush. The brush was first smeared on a glass side for co...
Conventional Pap Smear and Liquid Based Cytology for Cervical Cancer Screening – A Comparative Study
The study was undertaken to evaluate liquid based cytology (Pap spin) and to compare the sensitivity of Pap spin with conventional Pap smear. Pap smears were taken from 160 patients with gynaecologic complaints with Ayre’s spatula and endocervical cytobrush and slides prepared. The residual material on both the spatula and cytobrush were rinsed in Pap spin collection fluid and centrifuged. Dire...
Introduction: Fine-needle aspiration (FNA) cytology is a cost-effective technique of obtaining cellular specimens for diagnosis. It has many advantages over large needle core biopsies that make it quite suitable for out-patient departments and institutions without facilities for histopathologic diagnosis. Any site of the body can be sampled with FNA technique. Methods: Patients with liver disea...
OBJECTIVE The aim of this study was to determine the adequacy of archived and fresh fine needle aspiration (FNA) specimens from metastatic head and neck squamous cell carcinoma (SCC) for the molecular detection and genotyping of high-risk (HR) HPV. STUDY DESIGN Thirty-seven specimens from 26 patients diagnosed by FNA with metastatic SCC were included as retrospective specimens [19 slides stai...
OBJECTIVE We performed a prospective study to evaluate the diagnostic accuracy of cytologic examination in basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs), in order to assess its clinical value. Study design Samples were taken by the "scraping" technique which involves scraping with a scalpel blade directly over the skin tumor surface, smearing the cells onto several glass slid...
Qualitative and quantitative exfoliative cytology of normal oral mucosa in type 2 diabetic patients.
OBJECTIVE The main purpose of this study is to emphasize the relevance of exfoliative cytology as an additional tool to aid in the diagnosis of diabetes mellitus. MATERIALS & METHODS This is a comparative cross-sectional study. Oral smears were obtained from 10 diabetic patients and 10 healthy individuals. These smears were stained with Papanicolaou stain. The nuclear (NA) and cytoplasmic (CA...
Background: Cytological analyses of effusions or body fluids play an important role in the diagnosis of various lesions. Most importantly it gives a significant contribution in cancer research and staging of various tumors. Most commonly analysed fluids are pleural, ascitic, pericardial and occasionally peritoneal fluid/wash. Materials and Methods: A retrospective study for one year duration fr...
The presence of endometrial cells is considered an alarming finding in the gynecological smears of women in the second half of the menstrual cycle or women aged ≥ 45 years. In the case of postmenopausal women, the presence of atypical endometrial cells may represent endometrial abnormality and requires careful evaluation. We report a case of a 77 year-old postmenopausal woman, who presented abn...
