PATHOPHYSIOLOGY

• ETIOLOGY
• GENETIC
• CONGENITAL
• ACQUIRED
• INFECTIOUS
• AUTO-IMMUNE
• NUTRITIONAL
• TRAUMA

3
SIGNS

• OBJECTIVE MEASUREMENTS
• temperature
• pulse
• blood pressure

4
SYMPTOMS

• SUBJECTIVE INDICATIONS OF DISEASE
• pain
• fatigue

5
DISEASE, DISORDER, SYNDROME

• SYNDROME
• characteristic combination of signs and symptoms
  associated with a particular disease
• example acquired immune deficiency syndrome

6
PATHOGENESIS

• pattern of development of a disease

7
terms

• Acute conditions
• example - influenza
• Chronic disease
• example- arthritis
• local conditions
• inflammation around a splinter
• systemic
• fever

8
note

• some disorders and diseases can have both local
  and systemic affects. For example a bee sting,
  causes localized inflammation and systemic
  affects like increased blood pressure

9
Medical intervention changes disease progression

• signs and symptoms of disease
• medical assessment
• diagnosis
• therapy
• etiologic agent inactivated or symptomatic
  treatment
• analysis of therapy effects
• prognosis

10
medical intervention

• enhances the bodies capacity for self healing
• kills pathogenic agents
• treats symptoms of disease or disorder
• controls pain
• nutritional therapy supplies necessary nutrients

11
infectious diseases

• etiologic agent
• pathogen
• fungi, bacteria, protozoan, virus

12
infectious diseases

• incubation period
• time from exposure to time first signs and
  symptoms occur
• infectious period
• time that the sick person can transmit disease
  pathogens to other persons

13
Infectious

• disease- illness
• recovery or convalescent period
• or death

14
MECHANISMS OF DISEASE

• DISTURBANCES TO HOMEOSTASIS
• damage to cells
• damage to tissues
• changes in pH
• changes in production of biochemicals
• imbalances in gas, electrolytes, and fluids
• changes in structural components

15
types of diseases

• genetic diseases
• infectious ( caused by pathogens)
• pathogens- viruses, bacteria, fungi, protozoan
• tumors and cancers ( neoplasms )
• physical and chemical agents
• malnutrition
• degenerative

16
immune diseases

• autoimmune
• inflammation
• allergies
• immunodeficiencies
