of the body that connect the structures of the body together).
o It is presented by the inflammation of the joints (arthritis)
o It may be infective or non-infective.
o In most cases, all signs of inflammation are present (swollen joints,
hot, tender and red) and there is limitation of movements.
STEP 3: Common Types of Connective Tissue Diseases ( 5 minutes)
o Osteomalacia
o Osteoporosis
STEP 4: Common Connective Tissue Diseases (35 minutes)
|Activity: Small Group Discussion ( 15 minutes) |
| |
|DIVIDE students into small manageable groups |
| |
|ASK students to discuss on the following question |
|What are the common of connective tissue diseases? |
| |
|ALLOW students to discuss for 15 minutes |
| |
|ALLOW few groups to present and the rest to add points not mentioned |
| |
|CLARIFY and SUMMARIZE by using the contents below |
o This is the infection of the joints by pus-producing bacteria
o It is caused by any pyrogenic bacteria like staphylococci.
o The infection may start suddenly without any obvious cause or may occur
from other septic focus nearby like osteomyelitis
o The patients complain of pain, swelling and reduced movement of the joint
o This is arthritis due to congenital abnormality of uric acid metabolism,
leading to abnormal high uric acid in the blood.
o Uric acid is deposited in joints and also around the joints and in the
ear cartilages.
o The kidney may be damaged and kidney stones may form in them.
o The disease is commonest in men over 40 years.
o The acute episodes may be precipitated by alcohol excess, surgery,
infections or treatment with thiazide diuretics which raise serum uric
acid even in normal people.
o Patients experience irritability and malaise a day or two before acute
attack of gout and sudden severe pain starts in one joint especially that
of big toe.
