Study Notes
Pathology Overview
- Pathology studies diseases causing organ system abnormalities.
- Disease describes the body’s response to injury, leading to deviations from normalcy.
- Categories of disease: hereditary, traumatic, infectious, vascular, metabolic.
- Signs are objective, measurable manifestations of disease; asymptomatic individuals show no visible signs.
- Iatrogenic diseases result from medical treatment.
- Diagnosis involves identifying specific diseases, while etiology explores the underlying causes.
- Idiopathic diseases have unknown causes; prognosis predicts the expected disease outcome.
- A syndrome is characterized by a group of signs and symptoms; nosocomial infections occur in healthcare settings, contrasted with community-acquired infections from outside.
Respiratory System Conditions
- Conditions reflecting relative attenuation of X-rays include:
- Additive (Increased Attenuation): Acromegaly, Hydrocephalus, Sclerosis, Gout, among others.
- Destructive (Decreased Attenuation): Active osteomyelitis, Aseptic necrosis, Emphysema, Pulmonary conditions such as pneumonia, and pneumothorax.
Circulatory System Issues
- Additive conditions leading to increased attenuation:
- Aortic aneurysm, Ascites, Cirrhosis of the liver, Enlarged heart.
- Treatment includes broad-spectrum empiric intravenous antibiotics and removing indwelling catheters.
Inflammation and Hematology
- Inflammation is the initial response of tissue to injury.
- Permeable membranes allow fluid and cells to migrate between tissues.
- Granulation tissue replaces destroyed tissue following injury.
- Phagocytosis is the cellular process of engulfing and digesting particles or pathogens.
- Key steps in the inflammatory response:
- Blood flow alterations and changes in vascular permeability.
- White blood cells migrate to injured tissue.
- Phagocytosis and subsequent tissue repair occur.
Edema
- Edema is the abnormal accumulation of fluid in intercellular spaces or body cavities caused by an imbalance between hydrostatic and oncotic pressures.
- Anasarca is a severe, generalized form of edema.
- Elephantiasis results from localized lymphatic obstruction.
- Common causes include heart failure, renal failure, cirrhosis, and pregnancy.
Ischemia, Infarct, and Hemorrhage
- Ischemia is the interference of blood supply to an organ, depriving cells of oxygen.
- Infarct refers to localized ischemic necrosis due to arterial or venous blockages.
- Hemorrhage describes the rupture of a blood vessel, while a hematoma is a localized accumulation of blood within body tissues.
Background on Intracranial Conditions
- Intracerebral (intraparenchymal) hemorrhage occurs within functional brain tissue, leading to disrupted blood flow and neuronal death.
- Associated conditions include cerebral venous sinus thrombosis, arteriovenous malformations, and Moyamoya disease.
