While aspiration pneumonia constitutes the majority of pneumonia cases in the elderly, it remains highly underdiagnosed. We experienced a case of recurrent pneumonia and chronic cough that was later diagnosed as aspiration pneumonia and diffuse aspiration bronchiolitis (DAB) due to recurrent hemorrhaging from an intramedullary cavernous malformation. The patient was finally diagnosed when life-threatening respiratory depression caused emergency attention. This is the first report of hemorrhaging from an intramedullary cavernous malformation diagnosed due to aspiration pneumonia and DAB. These findings highlight the importance of considering aspiration in cases with recurrent pneumonia or chronic chough. The underlying cause may be a life-threatening condition.

We report the preparation of new C3- and CS-symmetrical molecules constructed on a triazine (TAZ) template. Anti-herpes simplex virus type 1 (anti-HSV-1) and cytotoxic activities against Vero cells of synthesized TAZ derivatives were evaluated. The results suggested that the presence of an electron-donating group(s) on the benzene ring in benzylamine groups on the TAZ template is an important structural factor for expressing a high level of anti-HSV-1 activity and low cytotoxicity for these C3 types of TAZ derivatives. Among the tested TAZ derivatives, compounds 4f and 7h showed the highest anti HSV-1 activities (EC50=0.98 and 1.23 µM, respectively) and low cytotoxic activities to Vero cells (50% cytotoxic concentration (CC50)=292.2 and >200 µM, respectively).
