The aim of this study was to evaluate the effect of periodontal inflammation on the approximal plaque pH after a sucrose rinse. Thirty-two periodontitis patients (aged 38-72 years; 9M/23F) were included. All patients were in need of periodontal surgery. Two non-adjacent interdental spaces, one healthy (no bleeding on probing [BoP] and probing pocket depth [PPD] < 4 mm) and one periodontally diseased (BoP and PPD ≥5 mm) were selected. Before and after surgery, the approximal plaque pH was measured before and after 2, 5 and 10 min after a 1-min rinse with sucrose solution. In periodontally diseased interdental spaces, a significant pH drop was seen 5 min after rinsing. In healthy spaces and after surgery, a significant pH drop was seen after 2 min. A multilevel regression analysis showed that greater probing pocket depths were significantly associated with pH change measured 5 min after rinsing ( < .05). Further on, the approximal pH drop after a sucrose rinse tended to be delayed in dentitions with ≥10% of PPD ≥5 mm ( = .052). The results suggest that an ongoing periodontal inflammation could temporarily neutralize acidic metabolic products after a sugar challenge. This may further suggest that plaque pH measured after a sugar rinse might be used to identify an ongoing periodontal disease.

Studies using genetic disruption of HPK1 function show enhanced T-cell signaling, cytokine production, and in vivo tumor growth inhibition. This profile of enhanced immune response highlights small molecule inhibition of HPK1 as an attractive approach for the immunotherapy of cancer.Areas covered This article summarizes the biological rationale for the inhibition of HPK1 as a potential adjunct to the current immuno-oncology (IO) therapies. The article primarily discloses the current state of development of HPK1 inhibitors.Expert Opinion The rapid increase in the identification of small molecule inhibitors of HPK1 should translate into a fuller understanding of the role of HPK1 inhibition in the IO setting. This understanding will be of huge importance in determining whether HPK1 inhibition alone will be sufficient for tumor growth inhibition or if combination with current IO therapies will be required. Injury to vascular structures such as the internal carotid artery (ICA) is a rare but catastrophic complication of minimally invasive transsphenoidal surgery. Thorough preoperative planning, and knowledge of anatomical landmarks, such as the intercarotid distance (ICD) reduce this risk. Numerous anatomical studies have been conducted regarding the transsphenoidal approach, but none have taken racial disparities into account. Since differences of the cranium, especially of the skull base exist, we sought to analyze anatomical differences of the sellar region in thin sliced T2-weighted MRI scans of 187 (87 male and 100 female) Asian, African American and Caucasian patients provided by the 'Human Connectome Project' (HCP). We found significant differences in the ICD between males and females across all races. Furthermore, we found that the ICD was up to 2.4 mm smaller in the Caucasian cohort compared to the African American/Asian cohort. These findings indicate that racial disparities regarding the sellar anatomy should be considered in patients undergoing pituitary surgery.
