RESUMEN
Iatrogenic acute aortic regurgitation (AR) is an uncommon condition, and its presentation as severe AR following coronary angiography or percutaneous coronary intervention (PCI) is exceedingly rare. We report a case of iatrogenic severe AR resulting from aortic valve injury caused by manipulation of the guiding catheter during PCI.
RESUMEN
A giant coronary artery aneurysm with arteriovenous fistula is a unique pathology having few surgical reports. An 82-year-old woman presented with a symptomatic giant left circumflex artery aneurysm with a fistula to the coronary sinus. The left coronary artery was dilated, and an aneurysmal change was visible from the left main trunk to the fistula. Surgery was performed to close the fistula and seclude all parts of the aneurysmal coronary artery. All coronary branches emerging from the aneurysm required bypass grafting. Herein, we present the history of this unusual case and our successful surgical strategy.

Antimicrobial activity of hinokitiol (beta-thujaplicin), which is a major component of the essential oil of Chamaecyparis obtuse, against Legionella pneumophila was investigated experimentally. The quantitative antibacterial assay of hinokitiol was carried out by the disk-diffusion method. The test concentrations of hinokitiol were 0.39 to 25.0 micrograms/disk, and the lowest concentrations of hinokitiol that showed growth inhibition against L. pneumophila were 1.56 micrograms/disk on B-SYE agar and 0.39 microgram/disk on B-SYE agar without iron.
