Question 34

ASO titer

Answer 34

Antistreptolysin O (ASO) titer is a blood test to measure antibodies against streptolysin O, a substance produced by group A streptococcus bacteria. Antibodies are proteins our bodies produce when they detect harmful substances, such as bacteria

you may need to repeat the ASO titer 2 weeks after your first blood sample

Positive ASO test confirms past infection; thus it’s useful to support the diagnosis of the poststreptococcal illness when it’s suspected, like poststreptococcal glomerulonephritis, pediatric autoimmune neuropsychiatric disorders associated with streptococcus (PANDAS), and rheumatic fever

test value below 200 is considered normal. In children under the age of 5, the test value should be less than 100

Question 43

Child with pharyngititis during abd examination became pale and hypotensive

Answer 43

Splenic rupture is a rare but life-threatening complication of Epstein-Barr Virus (EBV)-induced infectious mononucleosis (IM). It occurs in less than 0.5% of cases, with as many as 86% of those cases occurring spontaneously or atraumatically. It is the most frequent cause of death in IM.

Mononucleosis may cause enlargement of the spleen. The mechanism of splenic rupture secondary to infectious mononucleosis has been controversial. It is commonly believed that it is caused by an increase in intra-abdominal pressure or contraction of the diaphragm with vigorous cough, vomiting and defecation, leading to a compression of the spleen.

Question 44

Why does the flu vaccine have to change every year?

Answer 44

It’s because new strains of the virus are constantly appearing and evolving, so the vaccine must change along with them. Located around the world are influenza surveillance centers that annually monitor the most common strains, collecting data and identifying new and evolving strains

Influenza viruses constantly change through a process called antigenic drift. This is the random accumulation of mutations in the haemagglutinin (HA), and to a lesser extent neuraminidase (NA) genes, recognized by the immune system. It is most pronounced in influenza A viruses

Question 45

Erysipelas

Answer 45
