Pathogenesis
30
structural alteration
Either
- characteristic of a disease or
- diagnostic of an etiologic process
MORPHOLOGICAL CHANGES
31
signs and symptoms, clinical course, outcome, clinicopathologic relations
FUNCTIONAL DERANGEMENTS AND CLINICAL MANIFESTATIONS
32
information from patient’s history to identify the condition causing the disease.
Also refers to the name given to the disease
i.e. Diabetes, multiple sclerosis
DIAGNOSIS
33
predicting the likely or expected development of a disease
Improve of worsen
PROGNOSIS
34
Evidence of disease perceived by patients
i.e. pain, lump, diarrhea
SYMPTOMS
35
-Physical observations made by the person who examines the patient
i.e tenderness, a mass, abnormal heart sounds
-Elicited and observed during the physical
examination
Signs
36
Observations made by the application of tests or special procedures
-X-rays, blood counts, biopsies
Laboratory findings
37
Characteristic changes in tissues and cells produced by disease
LESIONS
38
Agents causing injury acting from outside the body
Exogenous disease
39
Acting from within the body
ENDOGENOUS DISEASE
40
WHY of disease
Etiology
41
Abnormalities of structure, function, or body metabolism that are present at birth.
Congenital defects
42
Caused by abnormalities in the genetic makeup at the chromosomal or genetic (gene) level (inherited from parents)
GENETIC DISORDERS
43
Usually classified by the type of offending organism
Bacteria
Fungi
Protozoa
Viruses
BIOLOGIC AGENTS
44
Caused by aberrations to the immune system
Immunologic disease
45
- exaggerated immune response to an antigen
Hypersensitivity reaction
46
deficiency of a component of the immune system
Immunodeficiency
47
abnormal (exaggerated) immune reaction against the self antigens of the host.
Autoimmunity
48
Disorders that stem from a deficiency in the activity of an enzyme involved in the synthesis or breakdown of intermediates
METABOLIC DERANGEMENTS
49
cause the body to injure itself by means of the inflammatory process
DEGENERATIVE AND INFLAMMATORY DISEASE
50
Progress is extremely rapid and generally threatening or resulting in death within a short time.
MALIGNANCY
51
Heat and cold
Electricity
Atmospheric Pressure changes
Radiation (electromagnetic and particulate)
PHYSICAL FORCES/AGENTS
52
-Subdivided into the manner of injury
-Poisoning (accidental, homicidal, or suicidal)
-Drug Reactions
Chemical injuries
53
They may include deficiencies or excesses in the diet, obesity and eating disorders, and
chronic diseases
NUTRITIONAL EXCESSES OR DEFICITS
54
cause of disease is unknown
Idiopathic
55
treatment, a procedure or an error may cause a disease
Iatrogenic
56
diseases that are caused by drugs that cross the placental barrier and harm the fetus
Teratogenic
57
transmitted by direct, intimate or by skin contact
Contagious
58
transmitted by sexual contact
Venereal
59
caused by pathogenic microorganisms
INFECTIOUS
60
transmitted by agents, fomites, vector or carrier
Communicable
61
– sudden and obvious onset; rapid cours
ACUTE
62
– acute fatal disease
FULMINATING
63
– slow onset, long duration
CHRONIC
64
– gradual progression with only vague or very mild signs; e.g. hepatitis
INSIDIOUS
65
– occurs during the course of another disease
INTERCURRENT
66
Duration acute
Short term, develops quicky
67
Duration chronic
Long time, milder
68
course of a disease in an individual, from onset to resolution, in the absence of intervention.
Natural history of disease
69
Disease has not developed, but risk factors are present.
Risk factors and disease in population
Stage of Susceptibility
70
promote development of a disease in an individual; indicates a high risk for the disease but not certain development
Predisposing factors –
71
– a condition that triggers an acute episode
Precipitating factor
72
- pathologic changes, no obvious manifestations
- rely on laboratory or screening methods
- brief as seconds OR long as decades
stage of pre-symptomatic disease
sub-clinical
73
- incubation period
- infectious disease
74
latency period
- chronic disease
75
Sufficient end-organ changes have occurred, so there are recognizable signs and symptoms to disease
Subclinical
76
Comprises the time in the early development of a disease when one is aware of a change in the body, but the signs are nonspecific
THE PRODROMAL PERIOD
77
Sufficient end-organ changes have occurred, so there are recognizable signs and symptoms to disease
STAGE OF CLINICAL DISEASE
78
Some diseases run their course and then resolve completely with or without treatment.
STAGE OF RECOVERY, DISABILITY, DEATH
79
any temporary or long-term reduction of a person’s activity as a result of an acute or chronic condition; note emphasis on loss of function rather than on structural defect
Disability –
80
– manifestations of disease subside
Remissions
81
– sudden increase in the severity or seriousness of the signs and symptoms during the course of disease
Exacerbation
82
– unfavorable conditions that arise during the course of a disease; new or secondary additional problems that arise after the original disease begins, e.g. congestive heart failure after a heart attack
Complications
83
– remote after effects produced by a disease; the potential unwanted outcomes of the primary condition, e.g. paralysis following recovery from stroke
Sequelae
84
– period of recovery and return to the normal healthy state; may last for several days or months
Convalescence or rehabilitation
85
the cessation of life; permanent cessation of vital functions
Death
