Prominent examples for exfoliative cytology are the aforementioned Pap smear, where cells are scraped from the cervix with a cervical spatula, or cells that are harvested from bodily fluids such as blood and urine, pleural and pericardial effusion, or ascites from the peritoneum. samples [8], which are taken for Pap staining test. Cytology samples can be collected from solid lesions by several techniques including: Aspiration cytology – fine needle aspiration (FNA): Ideal for cutaneous or subcutaneous masses since it avoids surface contamination. Adequate follow up cytology within a one year and a two year period revealed that 18/130 (14%) and 26/130 (20%) of patients had ASC or SIL respectively. These preluded the genesis of liquid-based cytology.14 rcame the limitations of the conventional procedure. All cases were received as liquid‐based samples and processed as ThinPreps (Hologic, Marlborough, MA). Of the unsatisfactory cases, 116 (89%) were co‐tested for HR‐HPV DNA.

This technique has opened several ways for working in health area, with favorable results and has been enhanced with some of the currently available technology programs, also allowing tabulating and analyzing informa-tion quickly and easily [9]. These cells can be recovered either from natural secretions such as urine, sputum and vaginal or prostate fluids or by artificial means such as paracentesis or lavage. Exfoliative cytology may act as an important diagnostic aid in early oral carcinomas with ulcerated surfaces, even in some clinically unsuspected cases malignancy can be detected. Exfoliative cytology is based on the monitoring the exfoliated cells or cells flake off the mucosa wither through natural or artificial means. Working off-campus?

Co‐testing for HR‐HPV DNA was performed using Hybrid Capture 2® (Qiagen, Germantown, MD) in the majority of patients. The cells may be obtained by such procedures as aspiration, washing, smear, and scraping, and the technique may also be applied to secretions such as sputum, urine, abdominal fluid, prostatic … Samples are usually collected using thin hollow needles of about 23-25 gauge. A retrospective review of anal cytology testing performed at the Cleveland Clinic between 01/01/2001 and 12/31/2015 was performed. By Kristina Dujmić. A sample of 1744 self-selected, mostly asymptomatic women was used to evaluate exfoliative cytology of nipple secretions as a screening technique for breast atypias. 77% of patients were HIV positive. Prompt repeat cytology and/or HR‐HPV DNA is recommended for high risk patients with non‐diagnostic cytology. respiratory,urinary, oral cavity/ gastrointestinal tracts, general application of exfoliative cytology, carcinoma that breaches basement membrane, -desquamated cells from epithelial suface. indications of exfoliative cytology mainly used for staging of cancer, indication of exfoliative cytology using cervicovaginal/ Pap smear, indication of exfoliative cytology in case of sterility. A variant of exfoliative cytology are swabs that look for the presence of bacteria. Exfoliative cytopathology (often referred to as non-gynaecological cytology) is an important part of the workload of all diagnostic pathology departments. 85% were males. assessment female hormonal status achieved by: where to get smears for determination of MI/ maturation index, conglomeration; XX ; buccal or vaginal mucosa. Hence, this study aims to assess the diagnostic accuracy of a new, cheaper sample collection tool in the field of oral exfoliative cytology through comparison with histopathology. The COP in non‐gynaecological cytology includes a document on exfoliative cytology presented here and another on fine needle aspiration (FNA), which will follow in a forthcoming issue of Cytopathology. Number of times cited according to CrossRef: Comparison of nylon‐flocked swab and Dacron swab cytology for anal HSIL detection in transgender women and gay, bisexual, and other men who have sex with men. 85% were males. Of those, 40 patients (34%) had a simultaneous positive HR‐HPV DNA. Unsatisfactory exfoliative anal cytology samples, 15-year experience with histologic, cytologic, and molecular follow-up. Exfoliative cytology screening of selected high risk patients is performed in many centers. For example, if a doctor suspects a patient has strep throat , he or she may take a swab of the back of the throat, deposit the results in a Petri dish , and recheck the dish in 24 hours to see if strep bacteria has grown.

Liver function Tests; Oligo-astheno-teratospermia. L. exfoliativus ] Microscopic examination of shed cells from body surfaces or cell harvested by rubbing or brushing a lesional tissue surface . It is implemented a prediagnostic tool in potentially malignant disorders like leukoplakia and oral cancers chiefly oral squamous cell carcinoma. It clearly has a role in the diagnosis of neoplastic disease but its role in establishing non-neoplastic diagnoses should also be recognised. Exfoliative cytology, for example, is widely employed as an aid in the continuous assessment of urinary tract tumors, and aspiration cytology in the diagnosis of thyroid dis eases.
