Identification of Foramen Ovale With H-Figure Fluoroscopic Landmark Improves Treatment Outcomes in Idiopathic Trigeminal Neuralgia.
Because it is traditionally difficult and time-consuming to identify the foramen ovale (FO) with fluoroscopy, we recently developed the H-figure method to acquire fluoroscopic view of FO with shorter procedure time and less radiation. However, the impact of such an H-figure approach on the clinical outcomes of trigeminal ganglion radiofrequency thermocoagulation (RFT) in treating idiopathic trigeminal neuralgia (ITN) remains unclear. ⋯ RFT of the trigeminal ganglion using the H-figure approach is associated with superior longer term clinical pain relief than the classic approach in treating ITN.

Outcomes and Disposition of Patients After Case Cancellation on Day of Surgery for Reasons Attributed to Medical or Anesthetic Care: A Retrospective Cohort Analysis.
Many day-of-surgery cancellations are avoidable, and different strategies are used to prevent these costly adverse events. Despite these past analyses and evaluations of positive interventions, studies have not examined the final disposition of patients whose cases were canceled in this late manner. This study sought to determine whether surgical procedures canceled for medical or anesthetic reasons were ultimately rescheduled, and the time elapsed between cancellation and completion. In addition, the resolution of the underlying issue leading to cancellation was examined. ⋯ Nearly a fifth of cases that are canceled on the date of surgery are never rescheduled and, if they are rescheduled, the delay can be substantial. Although the majority of patients whose procedure are canceled for reasons related to medical or anesthetic care have resolved the underlying issue that led to initial postponement, a significant portion of patients have no change in their status before the ultimate completion of their surgical procedure.

Postoperative cognitive dysfunction and delirium are undesirable consequences of surgery and anesthesia that regrettably do not have consistent predictive markers. Nor do they have reliable prophylactic or treatment methodologies. In an effort to better understand how anesthetic drugs alter the rate of postoperative delirium, Chang et al explore how patients with preoperative cognitive impairment respond to the influence of intraoperative ketamine. ⋯ Is it possible that ketamine and other drugs could be used as agents to stratify cognitive risk? Should we definitively avoid such drugs as potentiators of cognitive dysfunction? A variety of contextual limitations must be entertained when interpreting the results of this study as summarized in this infographic. These are also elaborated in greater detail in both the primary article as well as its attendant editorial. The reader is encouraged to review both in their entirety for an in-depth scope of understanding.

A Call to Action: A Specialty-Specific Course to Support the Next Generation of Clinician Scientists in Anesthesiology.
Clinical production pressure is a significant problem for faculty of anesthesiology departments who seek to remain involved in research. Lack of protected time to dedicate to research and insufficient external funding add to this long-standing issue. Recent trends in funding to the departments of anesthesiology and their academic output validate these concerns. ⋯ Directed toward early career academic anesthesiologists who wish to gain competency specifically in the fundamentals of clinical research and receive mentorship to develop an investigative project, the yearlong course will provide participants with the skills necessary to design research initiatives, ethically direct research teams, successfully communicate ideas with data analysts, and write and submit scientific articles. Additionally, the course, articulated in a series of interactive lectures, mentored activities, and workshops, will teach participants to review articles submitted for publication to medical journals and to critically appraise evidence in published research. It is our hope that this initiative will be of interest to junior faculty of academic anesthesiology departments nationally and internationally.

Reactive Oxygen Species Contributes to Type 2 Diabetic Neuropathic Pain via the Thioredoxin-Interacting Protein-NOD-Like Receptor Protein 3-N-Methyl-D-Aspartic Acid Receptor 2B Pathway.
The number of patients with diabetic neuropathic pain (DNP) continues to increase, but available treatments are limited. This study aimed to examine the influence of reactive oxygen species (ROS)-thioredoxin-interacting protein (TXNIP)-NOD-like receptor protein 3 (NLRP3)- N -methyl-D-aspartic acid receptor 2B (NR2B) pathway on type 2 DNP. ⋯ Our findings suggest that spinal ROS can contribute to type 2 DNP through TXNIP-NLRP3-NR2B pathway.
