Choanal bleeding due to nasopharyngitis.

Twenty-two patients with bleeding from the nasopharynx which due to secondary changes in acute nasopharyngitis were treated at the Fujisaki Hospital. The titers of IgG, IgM and IgA of the viral capsid antigen (VCA), IgG and IgA of the early antigen (EA), and EB nuclear antigen (EBNA) were measured. There was no correlation between season of coryza or changes in season and the onset of nasopharyngitis, except for a slightly greater occurrence during mid summer and mid winter. One of three patients with severe bleeding, underwent posterior nasal packing using a rolled 10 X 10 cm gauze sponge. The majority of cases of bleeding from the nasopharynx were most satisfactorily treated by administration of the ranitidine hydrochloride (Zantac) of a selective antagonist for the H2-receptor of histamine.
