Is maxillary mucosal cyst a manifestation of rhinosinusitis : results of a prospective three-dimensional CT study of ophthalmic patients?
Maxillary mucosal cysts are prevalent in nonrhinitic patients and do not reflect sinus or dental disease. Their presence should not be an indication for sinus surgery.
NoV epidemics resulted from the global spread of GII.4 strains that evolved under the influence of population immunity. Lineages show notable (and currently unexplained) differences in geographic prevalence. Establishing a global NoV network by which data on strains with the potential to cause pandemics can be rapidly exchanged may lead to improved prevention and intervention strategies.
