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.
A 75-year-old man, who had a history of coronary dissection after percutaneous coronary intervention in left anterior descending coronary artery, underwent coronary magnetic resonance. Magnetic resonance demonstrated coronary dissection in the distal portion of the left anterior descending artery. Both the true lumen with thick vessel wall and the false lumen with thin vessel wall were demonstrated in the cross-sectional images using T1-weighed black blood technique and T2-weighed black blood technique.

Apparent conductance changes observed in sequential measurements suggest the existence of bond fluctuation among the adsorption sites.

The aim of this study was to determine if low-intensity pulsed ultrasound would accelerate callus maturation when applied after distraction to limbs treated with opening-wedge high tibial osteotomy by hemicallotasis.
Methods: Twenty-one patients with symmetric grades of osteoarthritis and similar degrees of varus deformity in the two knees underwent bilateral one-stage opening-wedge high tibial osteotomy by hemicallotasis.
