Relationship between Duffy Genotype/Phenotype and Prevalence of Infection: A Systematic Review.

The Duffy protein, a transmembrane molecule, functions as a receptor for various chemokines and facilitates attachment between the reticulocyte and the Duffy antigen-binding protein. Duffy expression correlates with the Duffy receptor gene for the chemokine, located on chromosome 1, and exhibits geographical variability worldwide. Traditionally, researchers have described the Duffy negative genotype as a protective factor against infection.

[Pituitary apoplexy in pediatric patients: systematic review].

Introduction: Necrosis or hemorrhage associated with pituitary tumors is an infrequent complication. The term pituitary apoplexy is related to the development of an inflammatory process that leads to irritation of the meningeal and periselar areas. Regardless of the mechanism (hemorrhage or infarction), the extent of the hemorrhage and necrosis will produce an increase in intraselar pressure which, in turn, will lead to a more or less pronounced compression of neighboring structures, thus explaining the broad spectrum clinical.
