Explanation

A 17 y.o. patient complains of acute pain in the knee joint and t0– 380C. He was ill with angina 3 weeks ago. Objectively: deformation and swelling of the knee joints with skin hyperemia.Small movement causes an acute pain in the joints.Which diagnose is the most correct?Rheumatic fever is caused by group A streptococcus Beta hemolytic. It is an inflammatory disease that can involve the heart, joints (polyarthritis), skin, and brain. Rheumatic fever may occur following an infection of the throat (angina). The underlying mechanism is believed to involve the production of antibodies against a person's own tissues. Treating people who have strep throat with antibiotics, such as penicillin, decreases the risk of developing rheumatic fever.
