Malignant hyperthermia (MH) is a potentially lethal disorder of skeletal muscle triggered by anesthetic agents. A histomorphological examination of diseased muscle may provide insight into MH pathophysiology, but it is not a routine part of standard-of-care practice for the identification of MH-susceptibility. In this study, we investigated muscle histomorphology in a large cohort of MH-susceptible (MHS) patients and examined its relationship to genotype and phenotype. ⋯ Despite the inability of the histomorphological examination to identify consistent features in MHS patients, histology may serve as a potential adjunct to CHCT and aid in the identification of other myopathies. Nevertheless, the specifics of its utility ought to be assessed in other studies and by way of formal cost-effectiveness analysis.

Previous studies discussing the risk of medical misconduct amongst anesthesiologists differ in their conclusions. In Canada, there is a paucity of data regarding demographic information, disciplinary findings, and penalties received by anesthesiologists. The aim of this study was to identify potential characteristics for discipline within the specialty of anesthesiology by ascertaining disciplinary findings and types of penalties received by anesthesiologists and comparing these with cases of disciplinary action against other Canadian physicians. ⋯ Anesthesiologists in Canada have been subject to low rates of disciplinary action. Specifically, there have been low rates of sexual misconduct and unprofessional behaviour. Interventions to reduce disciplinary findings in anesthesiology could be directed toward bolstering education relating to standard of care issues, prescribing practices, and fraudulent behaviour.

Determining epidural catheter placement and accurately depositing corticosteroids at the site of the pathology in adults with chronic back pain can be challenging. Fluoroscopy is considered the standard of care for guiding epidural catheter positioning and subsequent injection in patients receiving epidural corticosteroids, but the technique has some limitations. We hypothesized that electrophysiological stimulation using the Tsui test is feasible for determining the appropriate epidural catheter position in adults with chronic back pain receiving epidural corticosteroids. ⋯ This study demonstrated that electrophysiological stimulation using the Tsui technique is feasible for epidural catheter positioning in adults with chronic back pain. It may optimize epidural steroid injection in this population.
