Objectives: Although lower-extremity muscle strength is associated with physical function, there are challenges in assessing the muscle strength of patients after hip surgery due to pain or limited cognitive function. The number of teeth is a characteristic that can be easily examined. Although the relationship between the number of teeth and physical function has been reported in recent years, there are no reports examining the relationship with prognosis in patients with hip fractures.

- 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 report a case of endotracheal tube malfunction, in which the inner surface of the tube peeled off during anesthesia. The patient, a 7-year-old boy, was under general anesthesia for the treatment of multiple dental caries. The damaged tube could have caused respiratory failure, putting the patient's life at risk.

Methods: We screened 343 surgical samples from 236 patients who had oral SCC, carcinoma in situ (CIS), or epithelial dysplasia, and we followed up their clinical outcomes for at least 5 years.
