In this study, we aimed to identify risk factors that predict the postoperative need for advanced or prolonged airway management in patients with severe odontogenic deep neck infections (DNIs). This retrospective case-control study included patients of both sexes aged ≥ 18 years who had undergone surgical drainage including debridement of necrotic tissues of odontogenic deep neck abscesses and necrotizing soft tissue infection under general anesthesia between April 2016 and September 2023 at a single center. The patients' characteristics, laboratory tests, and computed tomography (CT) findings were analyzed and compared between the difficult postoperative airway group, which required prolonged intubation or tracheostomy, and the short-term intubation group.

Purpose: This study aims to evaluate the image quality of computed tomography (CT) angiograms obtained using a virtual contrast augmentation technique, adding an iodine map to the contrast-enhanced images, obtained through a digital subtraction technique, reducing the dose of intravenous iodinated contrast medium compared to the conventional institutional standard technique.

Methods: This prospective investigation enrolled patients previously diagnosed with abdominal aortic aneurysms, who underwent two successive computed tomography angiographies (CTAs) of the aorta. One CTA was performed employing the virtual contrast enhancement boost technique with a 40% decrease in the intravenous contrast medium dose, while the other adhered to the conventional protocol without any reduction in contrast medium volume.

Article Synopsis
  • The study aimed to develop guidelines for antibiotic use during tooth extractions in cancer patients on denosumab, as there's a risk of medication-related osteonecrosis of the jaw (MRONJ).
  • It analyzed 68 cancer patients' antibiotic administration practices and their correlation with MRONJ after tooth extractions over a 10-year period.
  • Results showed a lot of inconsistency in antibiotic usage among hospitals, with amoxicillin being the most common; however, no significant link between MRONJ occurrence and the dosage or duration of amoxicillin was identified, suggesting a single preoperative dose may be sufficient.

Article Synopsis
  • Maintenance avelumab is recommended for patients with metastatic urothelial carcinoma (mUC) who have stable disease after first-line chemotherapy, while pembrolizumab offers an alternative option.
  • In a study of 626 patients, those transitioning from first-line chemotherapy to pembrolizumab had better outcomes in terms of response and progression-free survival compared to those moving to avelumab, especially if they had a partial response.
  • Overall survival rates were similar for both treatment options, highlighting that while pembrolizumab may provide better short-term efficacy, long-term survival outcomes remained unchanged.

In recent years, the association between neuroinflammatory markers and dementia, especially Alzheimer's disease (AD), has attracted much attention. However, the evidence for the relationship between serum-hs-CRP and dementia including AD are inconsistent. Therefore, the relationships of serum high-sensitivity CRP (hs-CRP) with dementia including AD and with regions of interest of brain MRI were investigated.

  • This study explored how Broca's area in the brain is linked to creativity, particularly during spontaneous improvisation with a guitar.
  • Twenty guitarists performed both improvised and formulaic music while their brain activity was measured, revealing significant responses in Broca's area only during improvisation.
  • The findings suggest that activity in Broca's area (BA45) is a common neural response related to creative improvisation, functioning similarly to how the brain plans and executes speech.

Joint go and no-go effects (joint Simon effects; JSEs) are considered to have a stimulus-response compatibility effect on joint reaction time tasks (joint Simon task) caused by the presence of other people. Additionally, JSEs are known to be associated with various social factors and are therefore a potential clinical marker for communicative function; however, the relationship with the personality that is associated with communication skills remains unclear. In this study, we focused on the association between JSE and personality traits.

Background/purpose: The incidence of medication-related osteonecrosis of the jaw is increasing worldwide, mostly due to the use of antiresorptive agents (ARAs) such as bisphosphonate (BP) and denosumab (Dmab). However, the proportion of BP-related osteonecrosis of the jaw (BRONJ) and Dmab-related osteonecrosis of the jaw (DRONJ) among all ARA-related osteonecrosis of the jaw (ARONJ) cases is not clear; this hinders appropriate treatment, recurrence-prevention planning, and avoidance of unnecessary Dmab withdrawal. Moreover, the causative drug administered at each disease stage remains unknown.
