Study Notes
Introduction to Disease
- Pathology is the study of disease
- Clinical pathology is the application of pathology to solve clinical problems
- Pathogenesis is the development of unhealthy conditions or disease
- Etiology is the study of the cause of disease
Key Terms
- Signs are objective evidence of disease observed on physical exam
- Symptoms are indications of disease perceived by the patient
- Homeostasis is a state of balance between opposing pressures operating in and around the cell or tissue
- Steady state is when an equilibrium between cells and environment is achieved and maintained
- Disease is a pathologic condition of the body in response to an alteration in homeostasis
Causes of Disease
- Direct results of trauma, physical agents, poisons
- Indirect results of genetic abnormalities, metabolic disorders, and nutritional disturbances
- May be temporary, permanent, or progressive
Cellular Response to Injury
- Cell injury can be reversible or irreversible
- Causes of cell injury include:
- Hypoxia (reduced oxygen availability)
- Anoxia (complete lack of oxygen)
- Toxic substances
- Microbial pathogens
- Genetic/metabolic disturbances
- Mediators of inflammatory and immune reactions
International Classification of Functioning, Disability and Health (ICF)
- ICF is a bio-psycho-social model that integrates abilities and disabilities
- Provides a common language for health professionals for documentation and communication
- Focuses on function (activity) in daily lives rather than disease
ICF Model
- Consists of two parts:
- Functioning and Disability (Body Functions and Structures, Activities, and Participation)
- Contextual Factors (Environmental Factors and Personal Factors)
- Impairment of Body Function: loss or abnormality of psychological, physiologic function of body systems
- Impairment of Body Structure: readily apparent during observation
- Primary and secondary impairments
- Activity Limitations: difficulty executing or inability to perform tasks or actions of daily life
- Participation Restrictions: problems a person experiences in life situations as measured against social standards
Categories of Disease
- Congenital: diseases present at birth (genetic mutation, chromosomal, multifactorial)
- Acquired: infection, injury, degeneration, dietary deficiencies/excesses, idiopathic, iatrogenic
Diagnostic Procedures
- Blood Chemistry:
- Complete Blood Count (CBC)
- Glucose levels
- Arterial Blood Gases (ABG): assess gas exchanges of oxygen and carbon dioxide in the lungs
- Urinalysis: calcium, protein, steroids, drug testing
- Radiology:
- Conventional radiography
- Computerized Tomography (CT scan)
- Bone Scan
- Magnetic Resonance Imaging (MRI)
- Myelogram
- Positron Emission Tomography (PET)
- Heart/Electrical:
- Echocardiogram
- Electrocardiogram (ECG/EKG)
- Cardiac catheterization
- Angiogram/arteriogram/arthrogram
- Doppler ultrasonography
- Electroencephalography (EEG)
- Electromyography (EMG)
- Other tests:
- Pulmonary function tests (PFT)
- Stress Tests (Graded Exercise Test)
- Lumbar Puncture
- Bronchoscopy
- Laparoscopy
- Oximetry
