TESTE DEIN WISSEN

Incidence Vs. Prevalence

Lösung anzeigen
TESTE DEIN WISSEN


The incidence represents the number of new cases arising in a population over a given time period, and prevalence is the total number of cases (new and existing cases) of the disease in a given population.

TESTE DEIN WISSEN


. Most broadly, the disease may be defined as the pattern of the response of living organisms to injury. When cells fail to adapt to the injury or the adaptive mechanism itself becomes harmful, disease results.

difference between cirrhosis and fibrosis?

Lösung anzeigen
TESTE DEIN WISSEN

“Anything that damages the liver over many years can lead the liver to form scar tissue. Fibrosis is the first stage of liver scarring. When scar tissue builds up and takes over most of the liver, this is a more serious problem called cirrhosis.

cardiovascular disease:

TESTE DEIN WISSEN

A type of disease that affects the heart or blood vessels. The risk of certain cardiovascular diseases may be increased by smoking, high blood pressure, high cholesterol, unhealthy diet, lack of exercise, and obesity.

difference: Morbidity and Mortality

Lösung anzeigen
TESTE DEIN WISSEN


Morbidity: illness that impairs the well-being / normal functioning of a patient (living with disease).

 • Mortality: illness causing the death of a patient (death from disease).

TESTE DEIN WISSEN

 

: the cause of a disease process (eg biological agents, chemical agents, or physical forces).

ie - hepatic cirrhosis - Cirrhosis is a late-stage liver disease in which healthy liver tissue is replaced with scar tissue and the liver is permanently damaged.  impaired liver function caused by the formation of scar tissue known as fibrosis due to damage caused by liver disease - caused by viruses, alcohol and storage disorders

cerebrovascular disease:

Lösung anzeigen
TESTE DEIN WISSEN

The term cerebrovascular disease includes all disorders in which an area of ​​the brain is temporarily or permanently affected by ischemia (restriction of blood flow thus oxygen as well) or bleeding and one or more of the cerebral blood vessels are involved in the pathological process. 

i.e Stroke

pathogenesis:

TESTE DEIN WISSEN

the reason for whatever is happening.


the development of a given disease; the sequence of cellular events that take place from the time of initial contact with the etiologic agent until the expression of the disease; the mechanism or how the disease process evolves

Pathological and the morphological manifestation

TESTE DEIN WISSEN


the changes in structure and function of tissues, organs and systems. Morphologic changes are described as both the gross anatomic and microscopic changes that are characteristic of disease.

Ischemia vs. Infarction

Lösung anzeigen
TESTE DEIN WISSEN

 Ischemia denotes the diminished volume of perfusion ( passage or a bloodstream) , while infarction is the cellular response to lack of perfusion.

TESTE DEIN WISSEN

difference between signs and symptoms?

Lösung anzeigen
TESTE DEIN WISSEN


signs - those signs that can be objectively observed or measured by a physician, eg fever, a swollen ankle, an abnormal heartbeat or the alteration of some physiological, biochemical or morphological parameter, and

clinical symptoms - subjective complaints described by the patient, eg pain, dizziness, nausea. In many cases though, these changes appear late in the disease process, long after a disease is present and has been acting at the cellular level.
