External Causes of Disease - 21 Flashcards
What are the 6 climactic factors
- Wind,
- cold,
- summer heat,
- dampness,
- dryness, and
- fire
Climate becomes a cause of diease only when it is either _________ or ___________
excessive or unseasonable
Each climactic factor is related to a yin organ. List them
- Wind - LV,
- cold - KI,
- summer heat - HE,
- dampness - SP,
- dryness - LU, and
- fire - HE
What does Chinese medicine see bacteria and viruses as systemically
caused by exterior climactic factors
What are the 6 stages (Shang Han)
- Tai yang,
- Yang Ming,
- Shao Yang,
- Tai Yin,
- Shao Yin,
- Jue yin
True or false Wind heat has a strong tendency to turn into interior heat rapidly
True
characterized by fever, pathogenic enters through mouth or nose
Wind heat
Once on the interior, the Heat tends to injure ____ rather quickly
Yin
What are the 4 levels of change resulting from an invasion of wind heat in a warm disease
- Defensive Qi - Wei;
- Qi;
- Nutritive Qi - Ying;
- Blood - Xue
Originally diseases from exterior pathogenic factors were considered to be caused only by _______
cold
What are some examples of warm diseases
influenza, mononucleosis, measles - rubella, meningitis, polio, encephalitis and SARS
A person has symptoms of sore throat, sneezing, aversion to cold, fever, slight sweating, toncillitis, thirst and a floating rapid pulse
exterior invasion of wind heat
What are some of the climates as causes of disease
- air-conditioning,
- refrigerated storerooms,
- hot kitchens,
- steel plants
What can cause an interior pattern of yin deficiency
Overwork or excessive sexual activity
How does an exterior pattern become and interior pattern
it penetrates into the interior
When a pathogenic factor is considered - invasion of external pathogen, where is this
Cou Li
signs and symptoms: arise suddenly and change rapidly, pain from joint to joint
Exterior wind
signs and symptoms: contraction, intense pain and watery discharges,
cold
Signs and symptoms: invasion of the body gradually and causes turbid, sticky discharges, feeling of heaviness in the joints and body, swelling
Damp
Signs and symptoms: dried body fluids
dryness
signs and symptoms: heat, thirst, and mental restessness
Heat and fire
What are the two major symptoms of exterior pathogenic factors
aversion to cold and fever occurring simultaneaously
What are the 4 degrees of aversion to cold, in ascending order of severity
aversion to wind, fear of cold, aversion to cold, shivers
Fever - explain what that means physiologically
emission of heat, not necessarily a raised temperature: patients forehead, dorsum of hands hot to touch
What are the three possibly degrees of fever
- Strong pathogenic factor and strong Zheng Qi: high fever
- Strong pathogenic factor with weak Zheng Qi, or visa versa: med fever
- Weak pathogenic factor and weak Zheng Qi: low fever or no fever
What is fever due to
the struggle between the bodies Qi and exterior pathogenic factors
The intensity of the fever is directly proportional to what
both the intensity of the pathogenic factors and the strength of the bodies Qi
Invasion of exterior pathogenic factors resulting from and exterior pattern, what would this look like
Exterior pattern, location exterior - dermis, simultaneous aversion to cold and fever
Invasion of exterior pathogenic factors without an exterior pattern
Exterior cold penetrated organs directly without development of exterior pattern with aversion to cold and fever.
Invasions of exterior pathogenic factors resulting in obstruction of muscles and channels
invade the muscles, sinews and channels causing obstruction of Wei Qi in Luo and sinew channels = joint pain. Bi syndrome - painful obstruction syndrome
Bi syndrome
painful obstruction syndrome
What are the primary causes of Bi syndrome
wind, cold, and dampness in its initial stages
consequences of invasions of external pathogenic factors without exterior pattern
Cold invades:
- ST causing acute epigastric pain and vomiting.
- Intestines causing acute diarrhea and abd. pain.
- Uterus causing acute dysmenorrhoea.
Patient will not go through aversion of cold fever.
