Class 1 Flashcards
(32 cards)
Pathophysiology
study of changes in body physiology which occur with disease & injury
Nosocomial Infection
Hospital acquired infection
Morbidity
illness
Mortality
death
Etiology
Study of the causes of disease
Idiopathic
unknown cause of disease
Iatrogenic
Adverse reaction caused by a health care professional.
Epidemiology
Study of patterns of disease in large groups of people.
Predisposing/Risk Factors
Heredity, age, gender, race, lifestyle, stress, environment.
Prevalence
Proportion of population found to have a condition.
Incidence
the probability of developing a particular disease during a given period of time
Prognosis
Predicting the outcome of a condition, likelihood of recovery
Sequelae
pathological condition resulting from a disease, injury, or other trauma.
Precipitating Factor
The catalyst for development or progression of a condition.
Aneuploidy
Chromosomal abnormalities.
- Increases as a women’s age increases
- Most common cause of miscarriages
- The result of nondisjunction
Turner Syndrome
Missing an X chromosome (monosomy), feminine appearance but no ovaries therefore sterile, heart defects
Down Syndrome (Trisomy 21)
Extra chromosome, low IQ, distinct facial features, predisposed to leukemia & alzheimers
Teratogen
Any drug or mechanism that interferes with the development of a fetus.
Mutation
Any inherited alteration of generation material.
Frameshift Mutation
Addition or deletion of one base pair.
Base pair substitution
One base pair is substituted for another
Nondisjunction Mechanism
Homologous chromosomes fail to separate normally during meiosis or mitosis.
Single Gene Disorders
Caused by a single gene that is defective or mutated.
-Include autosomal recessive, autosomal dominant & X-linked.
Autosomal Recessive
2 recessive genes are required for the disease to occur. 25% of the kids will have it
Ex: Cystic Fibrosis
