Answer to Question 1

ANS: C
Abnormalities in red cell membrane skeletal proteins are present in hereditary spherocytosis.

Answer to Question 2

ANS: D
The reticulocyte count is elevated in all hemolytic anemias at the time of hemolysis (unless an aplastic crisis is present). Of the other procedures listed only flow cytometry is sensitive enough to be useful for the diagnosis of paroxysmal nocturnal hemoglobinuria. The sucrose hemolysis and Ham tests have been replaced by flow cytometry.

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.
