etiology

Examples of etiology in the following topics:

• The Science of Epidemiology

  • Epidemiological studies include disease etiology, disease surveillance and screening, biomonitoring, and clinical trials.
  • Major areas of epidemiological study include disease etiology, outbreak investigation, disease surveillance and screening, biomonitoring, and comparisons of treatment effects such as in clinical trials.

• Chronic Fatigue Syndrome

  • Biological, genetic, infectious and psychological mechanisms have been proposed for the development and persistence of symptoms but the etiology of CFS is not understood and may have multiple causes.
  • It is unclear if these symptoms represent co-morbid conditions or are produced by an underlying etiology of CFS.

• Teratogens

  • The vast majority of recognized etiologies are genetic, with only 10% being attributed to environmental etiologies such as maternal health, infection, and toxicants.

• Depressive Disorders

  • A depressive disorder can be classified as substance-induced if its etiology can be traced to the direct physiologic effects of a psychoactive drug or other chemical substance, or if the development of the depressive disorder occurred alongside substance intoxication or withdrawal.
  • The etiology and treatment of persistent depressive disorders is much the same as that of MDD.
  • Little is known about its course or etiology.
  • Summarize the similarities and differences in diagnostic criteria, etiology, and treatment options among the depressive disorders

• Koch's Postulates

  • Koch applied the postulates to establish the etiology of anthrax and tuberculosis, but they have been generalized to other diseases.

• Regulation of H+ by the Lungs

  • The process that causes the imbalance is classified based on the etiology of the disturbance (respiratory or metabolic) and the direction of change in pH (acidosis or alkalosis).

• Coryza and Influenza

  • Coryza may not always have an infectious or allergenic etiology and can be due to something as innocuous as a cold wind, spicy food, or tender points in the muscles of the neck such as the sternocleidomastoid.
  • Treatment of coryza depends on etiology.

• Factitious Disorders

  • Though the etiology of factitious disorders is not well understood, risk factors for developing the disorder include childhood traumas, growing up with parents/caretakers who were emotionally unavailable due to illness or emotional problems, a serious illness as a child, history of working in healthcare and/or failed aspirations to work in the medical field, personality disorders, and low self-esteem.
  • Summarize the diagnostic criteria, etiology, and treatment of the two types of factitious disorder

• Specific Learning Disorder

  • Summarize the diagnostic criteria, etiology, and treatment of common learning disorders

• Technology and New Infectious Agents

  • Such time frames have been decreased to weeks or months by the use of powerful molecular techniques, as seen with the identification of severe acute respiratory syndrome coronavirus (SARS-CoV) within weeks of the first cases reported, the discovery of a new hantavirus in North America in 1993, and the detection of bacteria as etiological pathogens of human infections such as Ehrlichia chaffeensis and Anaplasma phagocytophilum in human monocytotropic ehrlichiosis and human granulocytotropic anaplasmosis, respectively.
