Study Notes

Histopathology

The study of diseases in tissues by examining samples under a microscope.
Crucial for diagnosing diseases like cancer, infections, and inflammatory conditions.
Pathologists analyze tissue structure to identify abnormal cells, infections, and tumors, providing vital information for clinical treatment.

Key Processes in Histopathology

Biopsy and Tissue Sampling: Collection of tissue samples from patients.
Tissue Processing: Involves fixation, embedding in paraffin, and cutting thin sections for staining.
Staining Methods: Common stains like Hematoxylin and Eosin (H&E) differentiate tissue structures.
Microscopic Examination: Tissue sections are examined under a microscope to detect abnormalities.

Laboratory Safety Procedures

General Safety Guidelines:
- No food or drinks in laboratory refrigerators.
- No shorts, sandals, or open-toed shoes in the laboratory.
- Minors or personal pets are not permitted in the laboratory.
- Secure any dangling jewelry, restrain loose clothing, and tie back long hair.
- Use of cell phones and music headphones should be avoided while working in the lab.
Equipment and Supplies:
- Instruments should meet electrical safety specifications and have written instructions.
- Eye wash station, safety shower, and first aid kits are standard facilities in a laboratory.
- Fire extinguishers and first aid must be checked monthly.
- Chemical material should be stored and safely secured.
- Acids and bases must be stored separately.
- All chemical material must be labeled with the name, characteristics, danger level, and precautionary measures.
Personal Protective Equipment (PPE):
- Laboratories must have available appropriate protective gears for all individuals: safety devices, goggles, gloves, lab coats, and face shields.
Laboratory Safety Guidelines:
- Method for disposal of hazardous wastes.
- Avoid handling sharp ends of instruments.
- Use forceps or other tools to remove sharp instruments from baskets and autoclaves.
- Workers should use appropriate hand protection when exposed to hazards.
- Laboratory accidents must be documented and investigated.
- Obtain medical advice immediately if major exposure occurs.
General Safety Precautions:
- Protect hands and forearms by wearing gloves and a lab coat or suitable long gloves.
- Wash hands frequently.
- Procedures involving toxic substances should be conducted in a fume hood or other suitable containment device.
- Laboratory workplace should be well-ventilated, clean, and organized.
- Smoking, sleeping, eating, and drinking are prohibited in the laboratory.

Applications of Histopathology

Cancer Diagnosis: Grading and staging tumors.
Infectious Disease: Detecting bacteria, fungi, or viruses in tissues.
Inflammatory Diseases: Assessing the nature and severity of inflammation.
Genetic Disorders: Identifying abnormal tissue structure linked to inherited diseases.
