Glossary
- myocardial infarction
- Myocardial infarction
- Myocardial infarction is necrosis of myocardial tissue which occurs as a result of a deprivation of blood supply, and thus oxygen, to the heart tissue. Blockage of blood supply to the myocardium is caused by occlusion of a coronary artery.
- 410 grams
- A normal heart weighs 300 grams (range: 270 to 360 grams).
- atherosclerotic narrowing
- Atherosclerosis is the deposition of lipid into the intima of arteries, resulting in narrowing of the vessel lumen.
- occlusion
- An occlusion is a blockage.
- thrombus
- A thrombus is a solid mass resulting from the aggregation of blood constituents within the vascular system.
- palliative surgery
- Palliative surgery provides alleviation but is not curative.
- 15,256 cells/cm²
- A normal white blood cell count is 4000-11,000 cells/cm².
- infiltrates
- infiltrate
- An infiltrate is an accumulation of cells in the lung parenchyma--this is a sign of pneumonia.
- consolidated
- Consolidation is the filling of lung air spaces with exudate--this is a sign of pneumonia.
- abscesses
- abscess
- An abscess is a collection of pus (white blood cells) within a cavity formed by disintegrated tissue.
- oral candidiasis
- Candidiasis is an infection by the fungus Candida in the oral cavity.
- hematuria
- Hematuria is the presence of blood in the urine.
- pyuria
- Pyuria is the presence of white blood cells (pus) in the urine.
- septic
- Sepsis is the presence and persistence of pathogenic microorganisms and their toxins in the blood.
- disseminated intravascular coagulation
- DIC is the development of small thrombi within the microcirculation throughout the body.
- acid fast bacilli
- Acid fast bacilli are not easily decolorized by acid during staining. This is characteristic of mycobacteria.
- 620 grams
- A normal left lung weighs 375 grams (range: 325 to 480 grams).
- 1230 grams
- A normal right lung weighs 450 grams (range: 360 to 570 grams.
- congestion
- Pulmonary congestion is the engorgement of pulmonary vessels with blood. The increased pressure caused by this engorgement leads to transudation of fluid through the capillary walls and into the alveolar and interstitial spaces.
- edema
- Pulmonary edema refers to the accumulation of fluid in the pulmonary alveolar and tissue spaces as a result of changes in capillary permeability and/or increases in capillary hydrostatic pressure.
- disseminated tuberculosis
- miliary tuberculosis
- Disseminated tuberculosis refers to the hematogenous spread of tuberculous lesions throughout the body. It is also known as miliary tuberculosis (which is so-called because the lesions resemble millet).
- tuberculosis granulomas
- A tuberculosis granuloma is a focus of granulomatous inflammation caused by CHRONIC tuberculosis infection. The granuloma consists of epithelioid cells (activated macrophages) surrounded by lymphocytes, plasma cells, and fibroblasts.
- anthracotic pigment
- Anthracotic pigment is coal dust deposited in the lungs--it is seen in coal miners, city-dwellers, and smokers.
- caseous
- "Caseous" means "cheesy."
- prostatic carcinoma
- Prostatic carcinoma is a highly metastatic form of cancer.
- significant pain and discomfort
- Back pain resulting from vertebral metastases of prostatic carcinoma is not uncommonly the presenting symptom which leads to the discovery of the carcinoma. Pain occurs late in the metastatic process and is an indicator of a poor outlook for a patient.
- peripheral region of the prostate gland
- Most commonly, prostatic carcinoma arises in the peripheral region of the gland.
- corpora amylacea
- Corpora amylacea are small hyaline masses of degenerated cells and inspissated secretions. They are so named because they resemble (but are categorically not) amyloid deposits.
