Disease
A condition of (abnormal function) involving anatomic structures or body systems
Pathology
The study of disease
Syndrome
Group of signs and symptoms that occur together and characterize a particular condition, suggest an underlying disease, or increase the risk of disease development
Diagnosis
Bonus: what is a differential diagnosis
Process of identifying a particular disease and includes evaluation of signs and symptoms, medical history, physical examination, laboratory test, and other procedures
Bonus: distinguishing a particular disease from others that possess similar signs and symptoms
Prognosis
A prediction of how the disease will progress and the chances of recovery based on the persons condition and the usual course of the disease as observed in similar situations
Signs
Objective evidence obvious to someone other than the affected individual
- observed and measured
Symptoms
Bonus: if disease occurs w/o symptoms, it’s called ___?
Subjective evidence perceived by an individual
Bonus: asymptomatic
Clinical manifestations
Collective term used to describe both signs and symptoms
Acute disease
When signs and symptoms have an abrupt onset, last a short time (less than 3 months), and then resolve (or bring death)
Hippocrates famous quote
Father of western medicine “do no harm”
Chronic disease
Diseases that have an insidious onset, with a gradual increase in signs and symptoms, and last for a long time
Subacute diseases
Refers to diseases with characteristics somewhere between acute and chronic diseases
Local disease
Affects only one area of the body
Ex. Athletes foot
Systemic disease
Distributed throughout the body rather than isolated to one area
Ex. Lupus erythematosus
Etiology
Causes or origins of disease
Etiologic Agents
essentially, what you can blame the disease on Includes pathogens, such as viruses or bacteria, congenital defects, inherited or genetic disorders, immunologic dysfunctions, metabolic derangements, degenerative changes, malignancies, nutrient deficiencies, and trauma
Idiopathic disease
A disease that does not have a known cause
Risk factors
Factors that increase, or decrease the chances of getting a particular disease
Non-modifiable risk factors
Ruiz factors that cannot be changed such as a persons age, family, history, or race
Modifiable risk factors
Ones that can be changed, such as lifestyle choices and environmental factors, including smoking diet, and levels of physical activity
Bonus: medical term for high blood pressure?
Hypertension
Complications of the disease
Conditions that arise as a disease progresses. Examples of complications are a person who develops congestive heart failure after experiencing a heart attack or a person diagnosed with diabetes, who develops cataracts and skin ulcers.
Epidemiology
Study of occurrence, distribution, and transmission of diseases in human populations
Endemic disease
One that is found regularly in people within local geographic regions or specific races of people
Epidemic Disease
Reported occurrences of disease that affect a large number of people at the same time within a geographic region, but, unlike endemic, epidemics eventually subside
Morbidity
Indicates the number of individuals affected by a particular disease within a certain population or geographic region
Comorbudities
A person can have several morbidities
Mortality
Includes the number of deaths within a certain population or a geographic region
Incidence
The number of new cases in a particular population during a specific period, usually a calendar year
Prevalence
Refers to the number of all existing cases (new and old) of a disease within a particular population
Hygiene
Used in relation to personal cleanliness
Sanitation
Used when referring to cleaning equipment, supplies, and the massage space
Autoimmune diseases
the body mistakenly attacks and destroys healthy tissue
Disorder
Disruption of normal body function, that may or may not involve a structural change
Cancer
Characterized by growth of abnormal cells that possess uncontrolled cell division, lack programmed cell death, and can accumulate into masses or tumors.
Deficiency disease
the individuals inability to digest and absorb a particular nutrient properly
Remissions
Periods when signs and symptoms of disease disappear, or diminish significantly
Exacerbation
Bonus what are they also known as
Periods when signs and symptoms of disease worsen or become more severe (example: fatigue, swelling, pain, fever).
Bonus- flareups or relapses.
Metastasize
Ability to invade other tissues
Degenerative diseases
Involved tissue breakdown caused by overuse or occur naturally as a result of the aging process
Genetic diseases
Caused by an abnormality in the genetic code
Bonus: osteoporosis vs osteoarthritis
Osteoporosis - BONE degeneration
Osteoarthritis- JOINT degeneration
Metabolic disease
Occur when the metabolism process fails, which causes the body to have too much or too little of an essential substance, such as hormones
What are Infectious diseases caused by?
Caused by pathogens, such as bacteria, fungi, viruses, protozoa, and pathogenic animals
Nosocomial Infection
Infections that occur or were acquired while in a hospital or medical facility
Congenital Disorders
Are present at birth. These disorders may be caused by genetic abnormalities, by maternal diet deficient in nutrients, exposure to radiation, poisons, certain medication’s, and disease causing organisms, such as rubella, or oxygen deprivation of the baby before or during birth
Traumatic disorder
Involve injury to body tissues, and are often caused by violence or accidents
Pathogen
Biologic agent capable of causing infectious diseases (viruses, bacteria, fungi, Protozoa, prions, and pathogenic animals)
Viruses
Nonliving entities that depend on a host cell for growth in replication.
Bacteria
Single-cell organisms; they can be spherical, spiral, or rod shaped; and appear singly or in chains. Most bacteria are not pathogenic and do not require living tissue for survival.
