Causes of death

Examples of Causes of death in the following topics:

• Autopsy

  • An autopsy or post-mortem examination is a specialized surgical procedure to determine cause of death.
  • A forensic autopsy is carried out when the cause of death may be a criminal matter, while a clinical or academic autopsy is performed to find the medical cause of death and is used in cases of unknown or uncertain death, or for research purposes.
  • For example, a forensic autopsy is carried out when the cause of death may be a criminal matter, while a clinical or academic autopsy is performed to find the medical cause of death and is used in cases of unknown or uncertain death or for research purposes.
  • A forensic autopsy is used to determine the cause of death.
  • The internal examination consists of inspecting the internal organs of the body for evidence of trauma or other indications of the cause of death..

• Effects of Smoking

  • Smoking is one of the leading causes of preventable death globally.
  • Smoking is one of the leading causes of preventable death globally.
  • The risk of dying from lung cancer before age 85 is 22.1% for a male smoker and 11.9% for a female current smoker in the absence of competing causes of death.
  • Tobacco is the single greatest cause of preventable death globally.
  • Also, environmental tobacco smoke, or second hand smoke, has been shown to cause adverse health effects in people of all ages.

• Infectious Diseases Today and in the Developing World

  • Malaria is the second leading cause of death in Africa, after HIV/AIDS and is the fifth leading cause of death from infectious diseases worldwide.
  • These pathogens are the cause of disease epidemics, in the sense that without the pathogen, no infectious epidemic occurs.
  • Said to be one of the world's oldest diseases, malaria is caused by one of four protozoans within the genus Plasmodium.
  • It is the second leading cause of death in Africa, after HIV/AIDS, and is the fifth leading cause of death from infectious diseases worldwide.
  • Said to be one of the world's oldest diseases, malaria is caused by one of four protozoans within the genus Plasmodium.

• Pressure Ulcers

  • Pressure ulcers, or bedsores, are lesions cause by unrelieved pressure that blocks blood flow to the skin, causing severe illness or death.
  • Decubitus ulcers have many causes such as unrelieved pressure, friction, humidity, shearing forces, temperature, age, incontinence, and medication.
  • Bedsores typically affect the elderly and individuals who are restricted to a prone position for long periods of time.
  • Bedsores are often fatal and are one of the leading iatrogenic causes of death reported in developed countries.
  • The most important care for a patient with bedsores is the relief of pressure.

• Sudden Infant Death Syndrome (SIDS)

  • Sudden infant death syndrome (SIDS) is marked by the sudden death of an infant that is not predicted by medical history.
  • The cause of SIDS is unknown, but some characteristics associated with the syndrome have been identified.
  • The unique signature characteristic of SIDS is its log-normal age distribution that spares infants shortly after birth — the time of maximal risk for almost all other causes of non-trauma infant death.
  • Supporting evidence for an X-linkage is found by examining other causes of infant respiratory death, such as suffocation by inhalation of food or other foreign objects.
  • It should only be applied to an infant whose death is sudden and unexpected, and which remains unexplained after the performance of an adequate postmortem investigation, including: an autopsy, investigation of the death scene and circumstances of the death and exploration of the medical history of the infant and family.

• Mortality

  • Mortality rate measures the number of deaths in a population over a given period of time.
  • If you have a tank of one thousand goldfish and 100 die in the first year, they exhibit a mortality rate, or crude death rate, of 100 deaths/1000 members of the population, or 10%.
  • Mortality rate is a measure of the number of deaths (in general, or due to a specific cause) in a particular population, scaled to the size of that population, per unit of time.
  • Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 (out of 1,000) in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total.
  • The causes of death also tend to vary between countries.

• The Final Ledger of Deaths

  • Compiling or estimating the numbers of deaths caused during wars and other violent conflicts is a controversial subject and historians note that available statistics are often unreliable.
  • Civilian casualties include deaths caused by strategic bombing, Holocaust victims, German war crimes, Japanese war crimes, population transfers in the Soviet Union, other war crimes, and deaths due to war related famine and disease.
  • For nations that suffered huge losses, such as the U.S.S.R., China, Poland, Germany, and Yugoslavia, sources often give only the total estimated population loss caused by the war and a rough estimate of the breakdown of deaths caused by military activity, crimes against humanity, and war-related famine.
  • Many of these deaths were caused by war crimes committed by German and Japanese forces in occupied territories.

• Rigor Mortis

  • Rigor mortis is the stiffening of all muscles of the body following death.
  • Rigor mortis is the stiffening of all muscles in the body following death.
  • After death, cellular respiration in organisms ceases to occur, depleting the corpse of oxygen used in the making of adenosine triphosphate (ATP).
  • This release of calcium is caused by the loss of ATP-mediated function of calcium pumps of the sarcoplasmic reticulum, due to ATP depletion in the absence of cellular respiration.
  • When activated they slide over the myosin bundles causing shortening of the cell walls.

• The Black Death

  • The masks were designed to protect them from putrid air, which was seen as the cause of infection.
  • Its theme was the universality of death, expressing the common wisdom of the time that no matter one's station in life, the dance of death united all.
  • This was met with varying success depending on the amount of rebellion it inspired; such a law was one of the causes of the 1381 Peasants' Revolt in England.
  • Severe depopulation and migration of people from village to cities caused an acute shortage of agricultural laborers.
  • Our apologies to Gwen's fans, but it's for the cause of education!

• Programmed Cell Death

  • Programmed cell death describes the death of a cell through a highly regulated process, and serves many functions in an organism.
  • Programmed cell-death (or PCD) is death of a cell in any form, mediated by an intracellular program.
  • Necrosis is the death of a cell caused by external factors such as trauma or infection and occurs in several different forms.
  • This video describes the process of apoptosis, or programmed cell death.
  • Explain the importance of programmed cell death, including apoptosis and autophagy
