1 Intro to Patho Flashcards
4 interrelated topics of pathophysiology
1 etiology
2 pathogenesis
3 clinical manifestations
4 treatments
etiology
- study of CAUSES or REASONS for phenomena
- ID’s casual factors that, acting in concert, provoke a particular disease
Idiopathic
cause for phenomena is UNKNOWN
Iatrogenic
cause results from UNINTENDED or UNWANTED medical treatment
Risk Factor
a factor that when present increases the likelihood of a disease
clinical manifestations
sings, symptoms, + syndromes
signs
objective/observed manifestation of disease
symptoms
subjective feeling of abnormality in the body
syndrome
etiology of signs + sympt has not yet been determined
stages/clinical course
latent period prodromal period subclinical stage acute clinical course chronic clinical course
latent period
time bw exposure of tissue to injurious agent + first appearance of signs/sympt
- also refers to a period during an illness when signs/sympt temporarily become mild or silent or disappear
- aka incubation time
remission
decrease in severity, signs, sympt
-may indicate disease is cured
prodromal period
time during which first signs/sympt appear indicating onset of disease
subclinical stage
patient functions normally; disease process are well established
acute clinical course
short-lived
-may have severe manifestation
chronic clinical course
- may last months to years
- sometimes following acute course
exacerbation
sudden increase in severity of disease, sings, or sympt
convalescence
stage of recovery after a disease, injury, or surgical procedure
sequela
subsequent pathologic condition resulting from an illness
treatment application
understanding the etiology, pathogenesis, and clinical consequences of a particular disorder/disease/illness may determine which treatments could be helpful
statistical normality in health and disease
estimate of diseases in a normal population, based on bell-shaped curve
sensitivity
probability that a test will be POSITIVE when applied to a person w a particular condition
specificity
probability that a test will be NEGATIVE when applied to a person without a particular condition
epidemiology
study of the patterns of disease involving populations
-examining the occurrence, incidence, prevalence, transmission, + distribution of diseases in large groups of population
endemic disease
native to a local region
epidemic disease
spread to many people at the same time
pandemic disease
spread to large geographic areas
