his left knee. He has a history of repeated infections with Candida, Staphylococcus,
and Klebsiella since the age of 14 months. Laboratory studies show an abnormal

result from the nitroblue tetrazolium reduction test. Cultures of the fluid from the
boil grow Staphylococcus aureus.

Q. A 10-year-old male presents with a history of recurrent infections, easy
bruising, and light sensitivity. On physical examination, he is noted to have

granules in peripheral blood cells. Genetic testing confirms a mutation in
the LYST gene. Which of the following normal cellular processes is most

Q. A 24-year-old caucasian woman presented to her primary care physician for
evaluation of new coffee - coloured urine noticed intermittently over the past five
days. Her last menstrual cycle was two weeks ago, and they have been occurring
regularly. There is no history of fever, melena, or hemoptysis. Her vital signs were
unremarkable. On initial evaluation, CBC, urinalysis, and renal ultrasound were
normal and urine pregnancy test was negative. A few days later, she developed
jaundice with abdominal pain. Repeat testing at that time showed the following: WBC
count 3600/mm3, hemoglobin 4g/dl, platelet count 189,000/mm3, MCV 75 fl, RDW 28,
reticulocyte count 10.9 %, total serum bilirubin 7.5 mg/dl, indirect bilirubin 5.5 mg/dl.
The urinalysis showed hemoglobinuria. Flow cytometry of peripheral blood showed
absent expression of CD55 and CD59 on 78% of red blood cells. Based on the flow
cytometry results, what do you think is most appropriate drug to use in this condition
a. Rituximab
