01 - Intro to Pathophys Flashcards
Regarding pathophsyiology describe “normal”
There is no “model” human being so our concept of “normal” is a range of presentations and we are looking for signs/symptoms that are out of that range to identify disease
How does genetics contribute to variations in normal?
Especially phenotypically, many varieties of “normal.” Genotypically, may be predisposed to conditions or diseases; family history.
How does culture contribute to variations in normal?
What is normal to one culture may not be normal to another (eg diet, number of children, rituals). These can also be potential predisposing factors to disease.
How does age contribute to variations in normal?
Different challenges face different age groups based on immune function, growth, bone/muscle wear and tear, ability to get around, etc.
How does sex contribute to variations in normal?
Gender: Self identity, doesn’t have much to do with our risk for disease.
Sex: Organs born with more often determine what at risk for.
How does stress contribute to variations in normal?
Different groups face different physical, mental, emotion, and psychosocial stresses. Prolonged increased stress can suppress the immune system.
How does lifestyle contribute to variations in normal?
Usually choices. Kids don’t have as much power over lifestyle. Behaviors such as exercise, sleep, recreastion, substance use can vary in what’s normal and what puts an individual at risk for health concerns.
How does environment contribute to variations in normal?
Housing, school, state, regional, national identification can change what’s considered normal. These can also potentially pose exposure concerns that can predispose an individual.
Define epidemiology and describe its role in disease states
The study of causes, patterns, and effects of disease and health conditions in a given population. Allows for research of different conditions with the goal of developing preventative methods and identifying risk factors for the condition.
Define pathophysiology
How disease processes work to cause dysfunction to the body
Define pathogenesis
Mechanism that causes the disease
Define etiology
Cause of a disease
Describe congenital etiologic cause of disease
Something you are born with; present when born (eg Down syndrome, birthmark)
Describe metabolic etiologic cause of disease
Our body processes. Partly impacted by the food we eat, genetics, ethnicity.
Describe degenerative/drug induced etiologic cause of disease
Degenerative: Changes as we age. Drug induced: Could be caused by recreational drugs or drugs taken under the provision of a provider.
Describe neoplastic etiologic cause of disease
Uncontrolled growth of an abnormal cell line. May be benign or malignant.
Describe immunologic/autoimmune etiologic cause of disease
Hypersensitivity: Over reaction. Immune deficiency: Under reaction (eg AIDS). Autoimmune: Destruction of one’s tissues by antibodies produced by one’s immune system.
Describe infectious/inflammatory etiologic cause of disease
Diseases that are usually secondary to a primary disease (eg infection, autoimmune disease).
Describe nutritional etiologic cause of disease
Malnutrition - not enough resources for the body - can create disease. Eg, protein deficiency = reduced osmotic pressure, decreased healing and antibody production; vitamin deficiency = interference in tissue integrity, biochemical reactions of metabolism.
Describe traumatic etiologic cause of disease
Physical force that mechanically disrupts the structure of the body which can disrupt function (eg injury).
