Thus, early detection remains the major cornerstone for the successful treatment of pulmonary malignancies. Bronchoalveolar lavage in detection of occupational lung diseases 4. • Intraoral exfoliative cytology, originally developed by Silverman and Sandler, although eliminates many of the disadvantages of the biopsy, by no means supplants the usual biopsy study. The utilization of exfoliative cytology as a diagnostic tool is dependent in part upon the decreased adherence of malignant cells to each other, and to well-defined cytostructure indications of malignancy. The principal indications for exfoliative cytology of the respiratory tract are as follows: Workup of a solitary pulmonary nodule detected on diagnostic or screening CT, Workup of a pulmonary nodule detected on CT in patients with a prior malignancy, Workup of pulmonary infiltrates to exclude infectious etiology. Procedure: This technique involves examination of exfoliated cells scraped from suspected oral lesions. Gonçalves JS, Vannucchi CI, Braga FC, Paula-Lopes FF, Milazzotto MP, Assumpção ME, Visintin JA.

Changes in anti-Müllerian hormone concentrations in bitches throughout the oestrous cycle. The exfoliated cells reflect the hormonal, in particular the oestrogenic state, of the bitch. The oestrus is characterised by a high cell number, initially superficial cells with pyknotic nuclei, later anucleated squamous cells that are located in cell nests. This may leave an unnecessary deposit on the tissues. Infections without inflammation (AIDS): cells of the superficial squamous epithelium in a dirty background which contains many different types of infectious agents, such as bacteria, fungi, etc.  |  NLM 1. Technic and indications]. However, sputum cytology is not recommended for screening lung cancer. [Phase contrast microscopic study of vaginal exfoliative cytology. 4.

Screening for oral cancer and its precursor lesions may be performed by dentists, dental surgeons, and other health care professionals. de Gier J, Beijerink NJ, Kooistra HS, Okkens AC. During early prooestrus, single parabasal cells are identified among erythrocytes and intermediate cells. Bernstein ML, Miller RL. This has given rise to a growing demand for pathologists experienced in cytological diagnosis. Exfoliative cytology is a rapid, non‐invasive procedure for assessing dysplastic change within the oral epithelium.

The diagnostic sensitivity of BAL for organisms in immunosuppressed people is 82 % for. A post-bronchoscopic sputum may be examined when the expectorated sputum is negative. Due to the oestrogenic influence, an increase in cell layers, keratinisation and exfoliation is observed in the follicular phase during prooestrus, such that the 3-4 layered epithelium in anoestrus becomes 20-layered during oestrus. A survey regarding oral exfoliative cytology was completed by 132 dentists in Virginia who were randomly chosen from a mailing list.

The examination isnotuncomfortable for the patient and can be repeated many times. The overall sensitivity increases with a combined use of different sampling modalities. Vaginal cytology has many practical applications in the evaluation of both the normal and abnormal bitch. The principal indications for exfoliative cytology of the respiratory tract are as follows: 1. Both bronchial brushing and bronchial wash can detect infectious and neoplastic lesions. The indications for repeat bronchial cytology specimens are poorly formulated, but include initial negative bronchial cytology associated with positive sputum cytology, and It is valuable for the detection of opportunistic infections, and since it samples multiple bronchi, it is also suitable for sampling diffuse lesions such as adenocarcinoma with a lepidic growth pattern. Carcinomas, both of the small cell and non-small cell types, are by far the most common malignancy of the respiratory tract. Residual material can be rinsed in collection medium and used to process additional LBP for special stains, immunostains, or cell block preparation, especially if tissue fragments are noted. Exfoliative vaginal cytology as an essential part of the gynaecological examination is a simple, non-invasive method for the determination of the phases of the oestrous cycle (anoestrus, prooestrus/oestrus, metoestrus) and is additionally applied in cases of silent heat, or suspected ovarian cysts, ovarian remnant syndrome, postpartal disturbances in the endometrial involution or Sticker … , Christopher VandenBussche2 and Syed A. Hoda3, Department of Pathology, Johns Hopkins University Department of Pathology, Baltimore, MD, USA, New York Presbyterian Hospital Weill Cornell Medical College, New York, NY, USA.

Vaginal cytology can be performed in any practice due to its simplicity and the limited equipment necessary (speculum, cotton wool wad, slide, staining and microscope). Exfoliative Cytology. The upper airway extends from the sinonasal tract to the larynx, and the lower tract extends from the trachea to the lungs. Diagnostic sensitivity of sputum cytology is directly proportional to the number of samples examined, and its accuracy approaches 95 % when five (5) sequential samples are examined. Thus, cytology can aid in age estimation of an individual by visualizing the cellular morphology. Exfoliative cytology is a rapid, non‐invasive procedure for assessing dysplastic change within the oral epithelium. The slides can be fixed in 95 % ethanol for Pap staining or air-dried for Romanowsky staining (e.g., Diff-Quik stain). Oral exfoliative cytology. conventional exfoliative cytology sample collection 3. At the time of diagnosis, 25 % of patients have regional metastasis, and 55 % of patients have distant spread of disease. The examination of exfoliative respiratory cytology is an efficient and cost-effective method for diagnosing respiratory tract lesions. Because the results are rapidly available, it is a useful addition to gynaecological examination to differentiate the stage of the cycle (anoestrus, prooestrus/oestrus, metoestrus) and to diagnose infectious, inflammatory and tumorous conditions in the bitch. The cytological examination of a spontaneously expectorated sputum is a noninvasive technique and can be used for the detection of infectious lesions and large centrally located tumors.
