Study Notes

Dysfunction, Disease, and Pathology

Dysfunction refers to an abnormality or impairment in the operation of a specified bodily organ or system.
Disease is the study of the patient's condition, focusing on the scientific study of suffering (pathos).

Why Study Disease?

To gain a better understanding of diseases and their causes.
For effective prevention and treatment.

How to Study Disease

Through the study of functional and structural (morphological) changes in disease.
Without pathology, the practice of medicine would still rely on myths and folklore.

History of Pathology

Follows the evolution of what was deemed to be the cause of disease.
Early thoughts on disease causes:
- Animism: supernatural forces or punishment for wrongdoing.
- Abnormality in humour: excess or deficiency in phlegm, black bile, yellow bile, or blood.
- Spontaneous generation: occurring spontaneously without a defined cause.

Advances in Pathology

Morbid anatomy:
- Internal examination of organs to identify visible changes caused by disease.
- Autopsies, necropsies, and post-mortem examinations first recorded as early as 300 BC.
- Giovanni Morgagni published De Sedibus et Causis Morborum per Anatomem Indagatis in 1761.
Microscopic and cellular pathology:
- Before the microscope, disease was thought to be caused by 'spontaneous generation'.
- List discovered germs, radiation, and chemicals as causes of disease.

Approach to Studying Disease

Study the pathology of a disease to gain insight and knowledge for a meaningful approach to solving clinical problems.
One disease can cause several symptoms and signs, and a specific clinical picture can have several underlying diagnoses.

How to Study Disease in this Module

Systematic approach: general pathology and specific pathology.
General pathology: mechanisms and characteristics of basic disease processes (e.g., inflammation, tumours, degenerative diseases).
Specific pathology: description of specific diseases as they occur in specific organs or organ systems (e.g., appendicitis, lung cancer, atherosclerosis).

Components of Learning about Disease

The Language: pathology of disease has its own vocabulary, which is the basis of clinical medicine.
The Process: logical and orderly way of thinking about diseases, including:
- How common is it and who is mostly affected?
- What causes the disease?
- What happens in the body when you have the disease?
- How does the disease manifest?
- Are there any complications and/or consequences due to the disease?
- What is likely to happen or what is the outcome going to be with treatment?
- What tests can or should we do to help us make a diagnosis?
- What is the treatment?
