Flashcards in Chapter 1 Deck (35):
1

Disease

impaired health as a result of injury

2

Pathology

study of changes in bodily structure and function that occur as a result of disease

3

Etiology

cause of disease

4

Idiopathic

unknown

5

Iatrogenic

happened due to medical treatment

6

Nosocomial

hospital-born diseases

7

Lesion

structural abnormality produced by injury

8

Pathogenesis

history and development (ex. smoking and lung cancer)

9

Pathophysiology

Functional changes

10

Prevalence

number of TOTAL cases at a given time

11

Incidence

number of NEW cases at a given time

12

Mortality Rate

rate of death from disease

13

Morbidity

degree of disability

14

Survival Rate

% of people who survive disease within a given time period after diagnosed

15

Age-Dependent Disease

diseases that are inevitable to occur with age (sight reduction)

16

Age-Related Disease

diseases MORE LIKELY to occur with age

17

Symptom

reported by patient, subjective

18

Sign

measurable, objective

19

Syndrome

collection of clinical signs and symptoms

20

Prognosis

predicted course and outcome of disease
(chances of complete recovery, survivability probability)

21

Remission

signs and symptoms subside

22

Exacerbation

increases the severity of signs/symptoms

23

Relapse

disease returns after its apparent cessation

24

Complication

abnormal state that develops in person already suffering from a disease

25

Acute Disease

sudden and rapid onset
decreases with age
ex. the flu

26

Chronic Disease

long term
managed vs. cured
increases with age
ex. cancer

27

Autopsy

gross examination of a dead person

28

Biopsy

microscopic examination of living tissue, cells, etc.

29

Sickness/Health

presence/absence of disease

signs and symptoms not included

30

Diagnostic Test

analysis of patient

31

Diagnostic Procedure

manipulation of patient

32

Validity

measuring what we want it to measure

33

Sensitivity

probability of test to be positive in the PRESENCE of disease

99% sensitive = positive that 99 out of 100 have disease

34

Specificity

probability of a test to be negative in the ABSENCE of disease

35

Palliative

treatments designed to relieve and manage symptoms

ex. cutting out tumor in throat to make it easier to swallow
