Molecules that contain bonds whose length significantly deviates from the average are of interest in the context of understanding the nature and limits of the chemical bonds. However, it is difficult to disentangle the individual contributions of the multiple factors that give rise to such bond-length deviations as reports on such molecules remain scarce. In the present study, we have succeeded in synthesizing hexafluorodihalocubanes of the type CFX () (X = Cl (), Br (), I ()), which represent a new series of molecules with unusual C(sp)-halogen bonds.

Background: Eagle syndrome is a rare disorder whereby an elongated styloid process (ESP) causes not only some otolaryngological symptoms, but also cerebrovascular events caused by compression of the carotid artery. In recent years a syndrome, denominated as Eagle jugular syndrome, involving internal jugular vein (IJV) compression caused by an ESP has been proposed as a variation of Eagle syndrome. Clinical impact of the Eagle jugular syndrome on neurosurgical procedures has not been reported yet.

Cardiac involvement has been reported in patients with coronavirus disease 2019 (COVID-19). We herein report a 41-year-old man who presented with recurrent paroxysmal atrioventricular block without showing significant cardiac injuries or comorbidities. The patient was diagnosed with COVID-19 and admitted to our hospital, where he was noted to have paroxysmal atrioventricular block.

Article Synopsis
  • The study is the first of its kind in Japan, surveying antimicrobial susceptibility in 246 samples from patients with various odontogenic infections, revealing high positivity rates for bacterial growth across four infection groups.
  • Streptococcus spp. and anaerobic bacteria were the main isolates, with notable resistance in Prevotella spp. to certain antibiotics due to β-lactamase production, though no resistance was found against carbapenems or metronidazole.
  • Sensitivity testing indicated that while penicillins and cephems were generally effective, Prevotella spp. required combination therapy involving β-lactamase inhibitors for better treatment outcomes.

We performed infarct exclusion repair of ventricular septal perforation(VSP) in a 63-year-old woman who was diagnosed with acute myocardial infarction(AMI) of the inferior wall. As VSP existed behind a fragile posterior papillary muscle, we excised the papillary muscle and sutured a bovine pericardial patch to exclude the infarct area of the whole septum and a part of the inferior wall. Mitral valve replacement and coronary artery bypass were also performed.
