Septicemia (Jun Jie's group)
How? Surviving Sepsis Campaign (SSC)
The Surviving Sepsis Campaign (SSC) is a global initiative to bring together professional organizations in reducing mortality from sepsis. The purpose of the SSC is to create an international collaborative effort to improve the treatment of sepsis and reduce the high mortality rate associated with the condition. The Surviving Sepsis Campaign and the Institute for Healthcare Improvement have teamed up to achieve a 25 percent reduction in sepsis mortality by 2009.
How? treatment
Treatments for Septicemia
The list of treatments mentioned in various sources for Septicemia includes the following list. Always seek professional medical advice about any treatment or change in treatment plans.
Hospitalization
Antibiotics - often in large doses
Intravenous antibiotics
Broad-spectrum antibiotics
Specific antibiotics - one the causative agent has been identified.
Intensive care
Life support measures
Treatment of any underlying condition
Supportive therapy
Antibiotics
Fluids
How does this affect the blood component?
Decrease or increase in white blood cells.
Positive blood culture (presence of foreign microorganism).
Platelet count drops.
Blood pressure increases
Heart beat elevates
Alternative Treatments for Septicemia
Alternative treatments or home remedies that have been listed as possibly helpful for Septicemia may include:
Anthracinum homeopathic remedy
Pyrogenium homeopathic remedy
Arsenicum homeopathic remedy
Carbo vegetabilis homeopathic remedy
Crotalus horridus homeopathic remedy
Why?
Why are there so many diseases with "sepsis," "septic," "septicemia," or "blood poisoning" in their name?
Unfortunately, both medical personnel and laypeople have used these terms interchangeably and then linked them to either a particular organism (usually bacterial) that can cause sepsis or to a site in the body in which an infection originates that leads to sepsis as described above. For example, meningococcal sepsis, meningococcal septicemia, septic meningitis, and meningococcal blood poisoning can refer to the same entity; an infection of the patient by the bacteria Neisseria meningitidis that has spread from the meninges (brain membranes) to the bloodstream, resulting in the patient having at least two of the four criteria outlined above for sepsis. Common examples of a body site used in the same way are puerperal sepsis, puerperal septicemia, puerperal or childbirth blood poisoning, and maternal septicemia postpartum. All four terms represent infection of the female reproductive system that leads to sepsis criteria for the patient. The infectious agent is not described when the body site is linked to "sepsis" or the other terms. The following is a short partial list of both organism and organ system (and organ-related) terms that are seen in both the lay and medical literature:
MRSA sepsis: sepsis caused by methicillin-resistant Staphylococcus aureus bacteria
VRE sepsis: sepsis caused by vancomycin-resistant Enterococcus species of bacteria
urosepsis: sepsis originating from a urinary tract infection
wound sepsis: sepsis originating from an infection of a wound
neonatal sepsis or septicemia: sepsis seen in newborns, usually in the first four weeks after birth
septic abortion: an abortion due to infection with sepsis in the mother
There are many more examples of linking terms to sepsis (for example, AIDS, tattoo, spider bite). Occasionally, terms like hemorrhagic septicemia are used to describe a symptom (internal bleeding) that occurs with sepsis. The trend in medicine currently is to decrease the use of the terms septicemia and blood poisoning in favor of the terms sepsis or septic, because sepsis is defined most concisely.
What? function of the blood component/ structure in circulatory system?
White blood cells - Involve in the production of Antibodies or Phagocytosis.
Platelet - Play a role in the clotting of blood.
Blood pressure and heart beat (speed) - Bring oxygen and food materials to the cells at a normal rate.

Leukopenia (Sean Phua's Group)
Leukopenia
i. What is the cause of the disease?
Ans: The reduction of white blood cells in the human body can be caused by cancer treatment like chemotherapy or radiation therapy as malignant cells overwhelm the bone marrow. Some illness like influenza or Hodgkin's lyphoma (a type of cancer that originates from lymphocytes) can also cause the reduction of white blood cells. Some medications like immunosuppresive drugs, such as sirolimus, mycophenolate mofetil, tacrolimus, and cyclosporine can also cause leukopenia. Leukopenia increases the chance of the patient getting an infection.
ii. How does the component of blood/ blood vessel affected in the disease?
Pseudoleukopenia can develop upon the onset of infection. The leukocytes are marginalized in the blood vessels so that they can scan for the site of infection. This means that even though there is increased white blood cell production, it will appear as though the white blood cell count is low from a blood sample, since the blood sample is of core blood and does not include the marginalized leukocytes.
iii. What is the function of the blood component/ structure in circulatory system?
White blood cells, or leukocytes, are cells of the immune system that defend the body against both infectious disease and foreign materials.
v. How will the absence of the blood component / structure affect the health of the patient?
With the decrease of white blood cells, the immune system becomes weak. With a weakened immune system, a person becomes much more vulnerable to even relatively minor infections.
Thrombocytopenia Groupwork
6)Corticosteroids: used to increase platelet production.
7)Lithium carbonate or folate: used to stimulate the bone marrow production of platelets
8)Platelet transfusions: used to stop episodic abnormal bleeding caused by a low platelet count
(if platelet destruction results from an immune disorder, platelet infusions may have only a minimal effect and may be reserved for life-threatening bleeding.)
9)Splenectomy: may be necessary to correct thrombocytopenia caused by platelet destruction (A splenectomy should significantly reduce platelet destruction because the spleen acts as the primary site of platelet removal and antibody production.)
10)(Patients with idiopathic thrombocytopenic purpura (ITP) may require high-dose intravenous immunoglobulin. Patients with thrombotic thrombocytopenic purpura (TTP) will probably require large-volume plasmapheresis (plasma exchange).)

1. Spend some time to think of the following questions using Questioning Techniques after watching the video:
i. What is the cause of the disease?
ii. How does the component of blood/ blood vessel affected in the disease?
iii. What is the function of the blood component/ structure in circulatory system?
iv. How does this blood component/ structure differ from the rest in the circulatory system?
v. How will the absence of the blood component / structure affect the health of the patient?
vi. How technology is used to facilitate the analysis of one’s state of health and improve one’s lifestyle?
vii. How technology is used to save lives with respect to the disease investigated?
We will be discussing the following diseases in the next lesson (Friday): Leukopenia, Thrombocytopenia, Coronary Heart Disease & Septicemia. You can do some research and read in advance to facilitate the discussion :) You can use the above questions to guide your research and readings.
