1. Immune System Conditions -by MariyaDemidovich

2. Allergy A hypersensitivity disorder of the immune system Major reaction is the inflammation response an allergen (an antigen that acts as an allergy reactant) Type I hypersensitivity (acute) disorder due to its immediate onset

3. Symptoms Itchiness Runny nose Red, watery eyes Hives Throat swelling This is particularly dangerous anaphylactic shock, where the throat closes due to swelling and the person goes into shock, can lead to death.

4. Common Types of Allergies Environmental Hay fever Mold Food Peanuts, shellfish Lactose intolerance Latex Contact dermatitis

5. Reaction/Onset An allergen that the individual has a particular sensitivity for comes in contact Antibodies (IgE) respond to this reactant Eventually through a positive feedback and a chemical cascade of events histamine and other chemicals are released Histamine creates an inflammatory response in the individual

6. Diagnosis Scratch Test The skin is scratched with small needles that each contain a small amount of different kinds of allergens After some time an inflammatory response is measured to see if the patient is sensitive to a certain allergen http://www.healthierchoices.ca/images /mri/tests_and_procedures_0.jpg

7. Diagnosis Blood Test The amount of IgE antibodies is measured in the patient’s blood. A high amount of IgE shows a sensitivity for possible allergic reactions

8. Treatment Usually pharmacological in nature. Antihistamines such as Singular and Advair are used to treat the allergic response.

10. Cancer of lymphatic tissues which is found in the lymph nodeshttp://www.oncologychannel.com/onc/Images/region_lymphnodes_head_neck.gif http://healthkut.com/blog/wp-content/uploads/2010/01/lymphnodes-axilla.jpg

11. Risk Factors Genetics Weak Immune System Prolonged use of growth hormone

12. Symptoms Swollen lymph nodes Night Sweat Fatigue

13. Treatment Chemotherapy Radiation

14. Sarcoidosis Immune system disease that affects different and often multiple body organs There are no known causes to date Fibrous lesions are found on different organs such as the lymph nodes, liver, lungs, eyes, etc. http://www.aafp.org/afp/2002/0415/afp20020415p1581-f5.jpg http://www.natural-holistic-health.com/wp-content/uploads/2010/01/sarcoidosis4-300x248.jpg

15. Symptoms Fatigue Weight Loss Dry Eyes Dry Cough Blurry Vision

16. Diagnosis Biopsies Chest x-rays PET Scans

17. Treatment Since the disease can spontaneously become chronic or remit many patients do not need continuous, intensive treatment. For more severe symptoms corticosteroid and steroids are used to treat the disorder
