Questions With Complete Solutions
iatrogenic disease
a condition that is caused by a medical treatment. E.g. someone
develops a blood clot after a bowel resection.
Acquired Infections
Herpes Zoster Oticus (Chicken Pox)
Mumps
Syphilis. Note: hospital acquired infections are also termed
nosocomial infections. These terms can be used interchangeably.
Idiopathic infection
It mean "unknown" cause. E.g. A patient with pulmonary
fibrosis with a unknown cause. A patient diagnosed with
pancreatitis but can not find the cause. This is called Idiopathic.
nosocomial infection
A disease acquired in a hospital or clinical setting. For e.g. A
hospitalized patient contracts respiratory MRSA. This is also
called an acquired infection.
Sensitivity, Specificity
In medical diagnosis, test sensitivity is the ability of a test to
correctly identify those with the disease (true positive rate),
, whereas test specificity is the ability of the test to correctly
identify those without the disease (true negative rate). See
picture
predictive value positive
The probability that a person with a positive test result has the
disease in question. I am 98% positive that my positive strep test
is accurate.
predictive value negative
The probability that a person with a negative test result does not
have the disease in question. I am 90% positive my
mammogram was an accurate negative (normal) results. There is
a 10% chance I could have an abnormal mammogram.
incidence rate
The number of people contracting a disease during a time
period. E.g. What is the risk of my friend contracting diabetes at
any given time.
prevelance rate
The number of individuals/unit who have disease at any one
time. The total number of cases. E.g. How many cases of
diabetes are there in the United States. That is the prevelance.
