Introduction to Pathology - Cell Injury - A New Pathology Series

Medicosis Perfectionalis2 minutes read

Pathology is the study of diseases, their causes, and risk factors, with biopsy being the gold standard for examination. Cell injury can result from various factors like hypoxia, chemical agents, and infections, leading to reversible damage.

Insights

  • Biopsy is the gold standard for examining diseases, involving both gross and microscopic assessments of organ tissues.
  • Cell injury, a reversible process distinct from cell death, can be caused by various factors such as hypoxia, chemical agents, physical agents, free radicals, inflammatory conditions, immunological diseases, microbiological agents, genetic conditions, and nutritional deficiencies, leading to a range of pathological conditions.

  • What is pathology?

    The study of diseases, their causes, and risk factors.

  • How is cell injury different from cell death?

    Cell injury is reversible, while cell death is not.

  • What are some causes of cell injury?

    Causes include hypoxia, chemical agents, physical agents, free radicals, inflammatory, immunological, microbiological, genetic, metabolic, and nutritional factors.

  • What can result from lung or heart diseases?

    Hypoxia or anoxia, leading to cell injury.

  • Can infections be a cause of cell injury?

    Yes, infections like abscesses, cellulitis, carbuncles can lead to cell injury.

Understanding Cell Injury and Disease Pathology

  • Pathology is the study of diseases, their causes, and risk factors, with biopsy being the gold standard for examination.
  • Examination involves gross examination of the organ's appearance and microscopic examination of tissue under a microscope.
  • Medicine encompasses over 10,000 conditions, starting with cell injury, which differs from cell death in being reversible.
  • Causes of cell injury include hypoxia, chemical agents, physical agents, free radicals, inflammatory, immunological, microbiological, genetic, metabolic, and nutritional factors.
  • Hypoxia or anoxia can result from lung or heart diseases, leading to cell injury.
  • Chemical factors like polycyclic hydrocarbons, alcohols, medications, heavy metals, and physical agents can cause cell injury.
  • Free radicals, inflammatory conditions, immunological diseases, microbiological agents, genetic conditions, and nutritional deficiencies can also lead to cell injury.
  • Intracellular accumulation of external or internal substances, aging, and senescence can contribute to cell injury.
  • Examples include cyanosis for hypoxia, alcohol toxicity, acetaminophen metabolism, heavy metal poisoning, and cellulitis from microbial infections.
  • Phenylketonuria, protein energy malnutrition like kwashiorkor, and edema due to low protein levels are further examples of cell injury causes and effects.

Cell injury and hypoxia: causes and treatments

  • Cell injury can be caused by various factors, including abscesses, cellulitis, carbuncles, and infections treated with antibiotics. Myocardial infarction can result in hypoxia leading to cell injury.
