Insights

Immunocytochemistry (ICC) aids in diagnosing pleural effusions by analyzing atypical cells. Standardizing ICC methods for effusions is crucial for reliable diagnostic insights.

Area of Science:

  • Cytopathology
  • Immunohistochemistry

Background:

  • Cytology is vital for diagnosing pleural effusions, often requiring immunocytochemistry (ICC) to identify atypical cell origins.
  • Pleural effusions present unique challenges for ICC, with a lack of standardized protocols in cytology.
  • Current methods lack standardization, hindering consistent diagnostic accuracy.

Purpose of the Study:

  • To review common cytologic preparations, fixatives, and antibodies for effusion ICC.
  • To highlight methods for optimizing ICC in effusion cytology.

Main Methods:

  • Review of commonly used cytologic preparations for effusions.
  • Analysis of fixatives and antibodies employed in effusion ICC.
  • Evaluation of cell block preparations for ICC.

Main Results:

  • Cell block preparations combined with appropriate antibody panels can replicate surgical pathology ICC conditions.
  • This approach allows for more accurate differential diagnoses in effusion cytology.
  • Standardization of ICC is achievable through specific preparation and antibody selection.

Conclusions:

  • Immunocytochemistry offers valuable diagnostic information for pleural effusion cytology.
  • Adherence to laboratory standardization practices is essential for reliable ICC results.
  • Optimized ICC protocols can overcome diagnostic challenges in effusion cytology.

Flow Cytometry

The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

Immunofluorescence Microscopy01:12

Immunofluorescence Microscopy

A fluorescence microscope uses fluorescent chromophores called fluorochromes, which can absorb energy from a light source and then emit this energy as visible light. Fluorochromes include naturally fluorescent substances (such as chlorophylls) and fluorescent stains that are added to the specimen to create contrast. Dyes such as Texas red and FITC are examples of fluorochromes. Other examples include the nucleic acid dyes 4’,6’-diamidino-2-phenylindole (DAPI), and acridine orange.

Immunocytochemistry and Immunohistochemistry

Immunocytochemistry (ICC) and immunohistochemistry (IHC) are techniques that use antibodies to check for specific proteins or antigens in a sample. The technique was first published by Albert Coons in 1941 to detect the presence of pneumococcal antigen in tissue sections from mice infected with Pneumococcus. Immunocytochemistry helps localization of proteins or antigens in individual cells like blood cells, stem cells, etc., while immunohistochemistry does the same for tissue samples.

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
