Use of sensors to quantify procedural idle time: Validity evidence for a new mastery metric.

Background: Quantification of mastery is the first step in using objective metrics for teaching. We hypothesized that during orotracheal intubation, top tier performers have less idle time compared to lower tier performers.

Methods: At the Anesthesiology 2018 Annual Meeting, 82 participants intubated a normal airway simulator and a burnt airway simulator.

Enriching Stem/Progenitor Cells from Dental Pulp Cells by Low-density Culturing.

Background/aim: Clonogenicity is a key feature of stem/progenitor cells. The present study aimed to enrich stem/progenitor cells from dental pulp cells by means of culturing the cells at a low clonal density with spatial separation and the evaluate differentiation potential of the surviving cells.

Materials And Methods: Pulp cells derived from wisdom teeth were seeded into wells of a 96-plate at a mean density of 1 cell/well and cultured for 2 weeks.

Accuracy of Bone Measurements in the Vicinity of Titanium Implants in CBCT Data Sets: A Comparison of Radiological and Histological Findings in Minipigs.

Purpose: The aim of this animal study was the determination of accuracy of bone measurements in CBCT (cone-beam computed tomography) in close proximity to titanium implants.

Material And Methods: Titanium implants were inserted in eight Göttingen minipigs. 60 implants were evaluated histologically in ground section specimen and radiologically in CBCT in regard to thickness of the buccal bone.

Postoperative bleeding risk for oral surgery under continued rivaroxaban anticoagulant therapy.

Objectives: The purpose of this study was to assess the risk of postoperative bleeding complications after oral procedures performed under continued mono or dual anticoagulation therapy with rivaroxaban (and aspirin).

Methods: This retrospective single-center observational study included 52 oral procedures performed under continued oral anticoagulant therapy with rivaroxaban (20 mg/day). Among them, two procedures were performed under continued dual therapy with aspirin (100 mg/day) added to the regimen.

Increased Postoperative Bleeding Risk among Patients with Local Flap Surgery under Continued Clopidogrel Therapy.

Purpose: The purpose of the study was to evaluate the influence of a continued antiplatelet therapy with clopidogrel on postoperative bleeding risk in patients undergoing skin tumor resection and reconstruction with local flaps or skin grafts under outpatient conditions.

Patients And Methods: The authors designed and implemented a retrospective clinical cohort study at the General Hospital Balingen. The primary endpoint was the bleeding ratio in patients with clopidogrel treatment in comparison to patients without any anticoagulant or antiplatelet therapy.
