Study Notes

Data Privacy

The right of an individual to control the collection, access, and use of personal information about them.
This applies to information held by the government and private sectors.

Data Privacy in the Health and Hospitals sector

Healthcare services heavily rely on information sharing between patients, healthcare workers, and institutions.
When patients feel confident about the safety and security of their information, they are more likely to provide complete and accurate data.

Key Data Privacy Act Actors

National Privacy Commission (NPC): The independent body responsible for administering and implementing the Data Privacy Act (DPA).

Tissue Processing

A process that prepares tissue samples for microscopic examination.
Methods improve tissue quality, reduce shrinkage, and enhance visualization.

Tissue Processor Methods

Traditional Tissue Processor:
- Utilizes vacuum and heat for faster processing and improved filtration of denser tissues.
- Uses a retort chamber for tissue processing with sequential reagent changes.
- Advantage: Can adjust processing time, temperature, and pressure.
Microwave Tissue Processor:
- Utilizes microwaves, vacuum infiltration, and proprietary reagents for processing.
- Advantages: Faster turnaround times, environmentally friendly reagents, and less nucleic acid denaturation.
Automated Tissue Processor:
- Uses automated systems with robotic arms to move tissue cassettes through stations containing different reagents.
- Advantages: Shorter processing time, increased efficiency, and greater profitability.

Tissue Embedding

The process of surrounding tissue with a solidifying medium to create a block for sectioning.
Aims to support the tissue and preserve it for archival purposes.

Tissue Embedding Systems

Tissue-Tek System:
- A combination of a paraffin dispenser, a metal plate for block creation, and a cold plate to solidify the paraffin.

Microtome

A mechanical instrument that cuts biological specimens into thin sections for microscopic examination.
Types: Manual, semi-automatic, and automatic.

Cryostat

A machine containing a microtome in a freezer.
Allows for cutting tissue sections at low temperatures (-10 to -40 °C).
First cryostat introduced in 1954.

Laser Microtome

Utilizes laser technology for precise cutting.
Enables non-contact slicing without causing thermal damage.
Can cut slices with thicknesses ranging from 10-100 µm.

Water Bath

Used to float tissue sections after cutting.
Maintains a temperature 10°C below the melting point of the embedded paraffin.
Typically kept at 40-50°C.

Drying

Removes excess water from slides after sectioning.
Electrothermal slide drying benches apply heat to further flatten the tissue.
Automated stainers often have drying ovens integrated.

Autostainer

Automated equipment for staining tissue sections.
Two types:
- Dips Slides into Stain (Linear Design): One slide at a time, moved through a series of staining solutions.
- Applies Stain to Slides (Batch/Carousel Design): Multiple slides moved through baths of staining solutions.

Staining Techniques

Capillary Gap Stainer: Force or draws stain between specimen slide and another surface.
Centrifugal Stainer: Sprays stain as the slides rotates past the spray nozzle.
Flat Stainer: Drops stain onto a flat slide.
Common staining practices include: PAP, AFB, Hematology, and IHC techniques.

Cover Slipping

The final stage of tissue processing where a coverslip is placed over the stained tissue section.
Protects the slide and enhances microscopic observation.
