Study Notes
Introduction to Pathophysiology
- Pathophysiology explores functional changes linked to specific diseases.
- Health encompasses physical, mental, and social well-being; diseases represent deviations from normal homeostasis.
Key Terms in Pathophysiology
- Pathology: The study of disease, indicating suffering.
- Pathogenesis: The developmental stages of a disease.
- Health: Achieved through following guidelines; alterations indicate disease presence.
- Homeostasis: A state of normal bodily functions, influenced by factors like age, gender, and time.
Structure of Pathophysiology
- General Pathophysiology: Analyzes overall pathological processes affecting multiple diseases (e.g., inflammation, shock).
- Special Pathophysiology: Focuses on specific organs/systems (e.g., cardiovascular, neurological disorders).
Morphological Changes
- Structural alterations in cells affect disease diagnosis.
- Changes can be macroscopical (visible) or microscopical (observed with a microscope).
Disease Terminology
- Etiology: The cause of a disease.
- Idiopathic: Unknown cause of disease.
- Iatrogenic: Disease resulting from medical intervention.
- Congenital Disease: Present at birth.
- Exacerbation: Worsening of symptoms.
- Remission: Disappearance of symptoms.
- Convalescence: Recovery phase post-disease.
- Complications: Additional problems arising from a primary disease.
- Prognosis: Expected outcomes (e.g., recovery, death).
- Therapy: Measures for promoting recovery.
Disease Stages and Clinical Course
- Risk Factors: Elements leading to disease onset.
- Latency Period: Time between exposure and disease onset.
- Prodromal Phase: Initial changes without symptoms.
- Clinical Onset: Presence of signs and symptoms; can be acute or chronic.
Clinical Manifestations
- Signs: Objective indicators (e.g., measured by a doctor).
- Symptoms: Subjective experiences (e.g., reported by the patient).
- Asymptomatic conditions may be detected through screening tests.
Risk and Precipitating Factors
- Risk Factors: Influencers on disease likelihood; can be modifiable (e.g., lifestyle) or non-modifiable (e.g., genetics).
- Precipitating Factors: Trigger disease exacerbation (e.g., cold weather).
Importance for Medical Students
- Understanding pathophysiology aids in diagnosing and treating diseases.
- Enables inquiry into disease causes, progression mechanisms, and symptom development.
Functions of Cell Organelles
- Nucleus: Stores DNA.
- Mitochondria: Energy production.
- Smooth Endoplasmic Reticulum (SER): Lipid production and detoxification.
- Rough Endoplasmic Reticulum (RER): Protein production for export.
- Golgi Apparatus: Protein modification and export.
- Peroxisome: Destroys lipids via oxidative enzymes.
- Lysosome: Responsible for protein degradation.
