Study Notes
Cyto Technology
- Involves studying human cells to detect diseases such as cancer using microscopy.
- Samples can be taken from the uterine cervix, lungs, gastrointestinal tract, or body cavities.
- Individual cells reflect normal and abnormal morphology of their tissue origins.
Factors Affecting Cell Appearance
- Technique used and level of cell maturation at collection time.
- The nature of the parent tissue: soft tissue, cysts, or solid organs.
- Sample medium, time between staining and collection, and type of fixative/stain influence results.
Basic Cell Structure
- Cells are membrane-bound structures essential for life and biological function.
- An adult human consists of approximately 10-100 trillion cells.
Tissues
- Tissues are aggregates of similar cells with specific structures and functions.
- Major types include epithelial, connective, muscle, haematopoietic, and nervous tissues.
Epithelia
- Composed of tightly cohesive sheets covering internal and external surfaces.
- Classification is based on cell shape and arrangement; includes simple and stratified types.
Early Cytology Origins
- The microscope, crucial for cytology, was advanced by pioneers like Antonie van Leeuwenhoek and Robert Hooke.
Development of Cytology
- Q Papanicolaou innovated the "Pap smear" for early uterine cancer detection and developed staining techniques.
- His work focused on the female genital tract, influencing the clinical adoption of cytology.
Key Terminologies
- Smear: Specimen spread on a slide for microscopic examination.
- Pap test: A cervical smear test named after Papanicolaou.
- Biopsy: Tissue sample removal for microscopic analysis.
- Cervical cytology: Examines cells from the cervix surface.
Cervical Neoplasia
- Cervical intraepithelial neoplasia (CIN): Precancerous changes in cervical epithelium, categorized as CIN 1, CIN 2, and CIN 3.
Diagnostic Procedures
- Liquid-based cytology: Harvested cervical cells placed in a transport solution before laboratory examination.
- LLETZ: A treatment for removing abnormal cervical tissue, using a wire electrode.
Exfoliative Cytology
- Involves examining cells shed from epithelial surfaces or collected by physical means.
- Common collection sites include the skin, urinary tract, cervix, and bodily fluids.
Advantages of Cytopathology
- Offers rapid, inexpensive diagnoses and is effective in assessing infectious diseases.
- Allows for repeated sampling without tissue injury and monitors therapy progress.
Disadvantages of Cytopathology
- Relies on individual cell observation, which can limit diagnosis accuracy.
- Final diagnosis may require confirmation through histopathological examination.
Techniques in Exfoliative Cytology
- Studies involve direct smears and concentrated materials via centrifugation or filtration.
- Concentration techniques are vital for analyzing watery and dilute body fluids.
Fine Needle Aspiration Cytology
- A technique for acquiring cells from non-shedding organs, useful in various diagnostic scenarios.
